  However, in the above device, there is a possibility that the filling material filled in the filling region and the air mixed in the filling material expand due to a change in temperature or a change in atmospheric pressure, and the filling material naturally leaks to the outside. is there.

  The present invention has been made to solve such problems, and an object of the present invention is to provide a filler extrusion container in which the leakage of the filler is prevented and the quality is improved.

The filling material extruding container according to the present invention extrudes the filling material filled in the filling region in the container as the moving body disposed in the container moves forward and emerges from the opening at the tip of the container. The container includes a front portion of the container and a rear portion of the container that is rotatable relative to the front portion of the container. The container includes a first threaded portion and a second threaded portion, and the container front portion. When the container and the rear part of the container are relatively rotated in one direction, the screwing action of the first screwing part and the second screwing part works together to move the moving body forward and screw the first screwing part. When a predetermined amount of work is applied, the screwing of the first screwing part is released, and when the relative rotation is further performed in one direction, only the screwing action of the second screwing part works to advance the moving body, When the container front and the container rear portion are relatively rotated in the other direction in the opposite direction of the one direction, the meshing operation of the first engagement portion and a second engagement portion When working moving body is retreat Shi certain amount retracted back to, it is characterized in that the meshing operation of the first engagement portion is to stop further relative rotation of the stop and the other direction.

  According to such a filling product extruding container, when the container front part and the container rear part are relatively rotated in one direction, the moving body moves forward, and the filling material filled in the container is pushed out from the opening at the tip of the container. While appearing and in use, when the container front part and the container rear part are rotated relative to each other in the other direction, which is the opposite direction of one direction, the moving body at an arbitrary advanced position moves backward. . For this reason, after use, even if a predetermined space is formed inside the opening at the front end of the container and the filling material and air mixed in the filling expand due to a change in temperature or pressure, the opening at the front end of the container The predetermined space provided on the inner side of the part prevents the filling material from leaking from the opening, and the quality is improved. Further, when the container front part and the container rear part are rotated relative to each other in the other direction, the moving body at an arbitrary position advanced advances and stops by a certain amount, in other words, it does not retract beyond a certain amount, It is possible to prevent the moving body from returning too much, so that the filling material does not readily appear from the opening at the next use, and usability (ease of use) is improved.

  Here, as a configuration of the filling extrusion container that preferably exhibits the above-described operation, specifically, the container front part is configured by a filling member and a main body cylinder, the container rear part is configured by an operation cylinder, and the moving body is Further, there is a configuration that can be rotated synchronously with the operation cylinder and can move in the axial direction, and moves forward / backward by relative rotation of the filling member and the main body cylinder and the operation cylinder.

  In addition, as a configuration of the filling extrusion container that preferably exhibits the above action, specifically, the front part of the container has a locking member on the rear end side of the rotating member that is rotatably disposed in the rear part of the container. A structure is also possible in which the movable body is connected to the stop portion so as to be able to rotate synchronously, and the movable body can be rotated synchronously with the rear portion of the container and can move in the axial direction.

Further, as a configuration of the filling extrusion container that preferably exhibits the above-described operation, specifically , the first screwing portion is formed by screwing the operation tube and the moving screw tube, and the second screwing portion. Is configured by screwing a moving screw cylinder and a moving body. The moving screw cylinder can be rotated synchronously with the main body cylinder and can be moved in the axial direction. The moving body can be rotated synchronously with the operation cylinder and can be moved in the axial direction. When the container front part and the container rear part are relatively rotated in one direction, the screwing action of the first screwing part and the second screwing part works together to move the moving body forward, When the screwing action of the screwing part works for a predetermined amount, the screwing of the first screwing part is released, and when it is further rotated relative to one direction, only the screwing action of the second screwing part works. A configuration in which the moving body moves forward is mentioned.

Further, as a configuration of the filling extrusion container that preferably exhibits the above-described operation, specifically , the first screwing portion is formed by screwing the main body cylinder on the container rear side and the moving screw cylinder, The threaded portion is configured by screwing the moving screw cylinder and the moving body, and the rotating member is connected to the front of the container so as to be able to rotate synchronously, and the moving screw cylinder is connected to be able to rotate synchronously and move in the axial direction. The movable body can rotate synchronously with the rear portion of the container and can move in the axial direction. When the front portion of the container and the rear portion of the container are relatively rotated in one direction, the first screwed portion and the second screwed portion. When the moving body moves forward with a predetermined amount of screwing action of the first screwing part and the screwing action of the first screwing part works for a predetermined amount, the screwing of the first screwing part is released and further rotated in one direction. Then, the structure which only the screwing effect | action of a 2nd screwing part works | functions and a moving body advances is also mentioned.

  Here, it is preferable to include a biasing means for biasing the first screwing portion so that the screwing of the first screwing portion is released when the first screwing portion is released. When such a configuration is adopted, when the screwing of the first screwing part is released, the first screwing part is screwed back by the biasing force of the biasing means, and accordingly, the container front part and When the rear portion of the container is relatively rotated in the other direction, the screwing action of the first screwing portion works without trouble and the moving body moves backward. In addition, when the relative rotation in one direction is continued, the screwing release of the first screwing portion and the screwing return by the urging means are repeated, thereby causing a click feeling and the relative rotation in one direction. And the degree of movement of the moving body are perceived by the user.

  The moving body has one of the second screwing portions, and the other of the second screwing portions is urged by the urging means in the screwing return direction of the first screwing portion. When a piston for sliding the inside of the filling area and pushing out the filling material is attached to the tip of the cylinder, a sliding resistance is generated between the piston attached to the moving body and the filling area. The resistance becomes the resistance of the urging force of the urging means acting on the movable body via the second screwing part when the first screwing part is screwed back by the urging force of the urging means. There is a possibility that the first screwing part may not be screwed back by the biasing force of the biasing means. Therefore, it is preferable that the movable body is movable by a predetermined amount in the axial direction with respect to the piston. When such a configuration is adopted, the moving body is moved by a predetermined amount in the axial direction by the urging force of the urging means without receiving the sliding resistance between the piston and the filling region, and thereby the first screw is moved. The mating part is smoothly and satisfactorily screwed back.

  Further, it is preferable that the lead of the first screwing portion is made larger than the lead of the second screwing portion. When such a configuration is adopted, when the container front portion and the container rear portion are relatively rotated in one direction, the moving body quickly moves forward according to the large (coarse) lead of the first screwing portion and the predetermined space is Is immediately removed, and when the relative rotation in one direction is continued and the first screwing portion is released, the moving body slowly advances in accordance with the small (fine) lead of the second screwing portion. Then, when the filling material appears appropriately from the opening at the tip of the container and is put into use, and the container front part and the container rear part are rotated relative to each other in the other direction after use, the moving body is moved to the first threaded part. The predetermined space is immediately formed by quickly retreating according to a large lead. As a result, usability (ease of use) is further improved. Here, the lead is a distance that advances in the axial direction when the screw is rotated once.

  As described above, according to the filled product extruding container according to the present invention, leakage of the filled material to the outside is prevented and the quality is improved, and the usability is improved because the filled material is not easily appeared.

In this state, a predetermined space for the moving screw cylinder 5 to move forward is provided between the rear end surface of the filling member 1 and the tip end surface of the spring portion 5b of the moving screw cylinder 5. Note that this predetermined space may be omitted. As shown in FIG. 1, a cap 10 is detachably attached to the filling member 1.

  Next, an example of the assembly procedure of the filling extrusion container 100 having such a configuration will be described with reference to FIG. First, the screw cylinder 4 is attached to the operation cylinder 3, then the O-ring 15 is attached to the operation cylinder 3, and then the main body cylinder 2 is attached to the operation cylinder 3 to obtain an operation cylinder assembly. On the other hand, the moving screw cylinder 5 is screwed into the moving body 6. In this case, the moving screw cylinder 5 is not screwed to the end, and the screwing is completed at the position where the moving body 6 has moved by the rotation when the moving screw cylinder 5 is screwed to the screw cylinder 4 to the end. To do. In order to leave this amount of movement, it is preferable to position the moving screw cylinder 5 in the axial direction using a jig. Then, the piston 7 is attached to the moving body 6 to obtain a moving body assembly.

  Next, the movable body assembly is inserted from the opening side of the main body cylinder 2 of the operation cylinder assembly, and the protrusion 6f of the movable body 6 is engaged between the protrusions 3g and 3g of the shaft body 3y of the operation cylinder 3. The moving body 6 is extrapolated to the shaft body 3y, and the moving screw cylinder 5 is engaged with the rear half of the knurling 2a of the main body cylinder 2 in the rotational direction while the moving screw cylinder 5 is engaged with the main body cylinder. 2 while urging the tip (open end) of the spring part 5b of the moving screw cylinder 5 in a direction (right side in FIG. 29) against the urging force of the spring part 5b by a cylindrical jig. Then, the operation cylinder 3 is rotated in the rewinding direction to the position where it stops. By the rotation of the operation cylinder 3 in the rewinding direction, the first screwing portion 8 is screwed and a screwing action works, and by the cooperation with the rotation preventing portion 60 of the moving screw cylinder 5, the moving screw cylinder 5 is While being screwed into the screw cylinder 4 to the end, the screwing action of the second screwing portion 9 works, and by cooperation with the rotation preventing portion 50 of the moving body 6, the moving screw cylinder 5 to the end. The moving body 6 that is not screwed is screwed from the middle position to the end, and the main assembly 40 is obtained.

  As another example of the assembling procedure of the main assembly 40, the moving screw cylinder 5 is screwed into the moving body 6 to the end to obtain the moving body assembly. Then, the moving body assembly is similar to the above. And inserting the movable body 6 into the shaft body 3y of the operating cylinder 3 and inserting the moving screw cylinder 5 into the main body cylinder 2 from the opening side of the main cylinder 2 of the operation cylinder assembly. While urging the tip of the spring part 5b of the moving screw cylinder 5 in a direction against the urging force of the spring part 5b by a cylindrical jig, the operation cylinder 3 is temporarily rotated in the feeding direction, and the operation cylinder 3 By rotating in the feed-out direction, the screwing action of the second screwing part 9 is exerted, and the moving body 6 is advanced with respect to the moving screw cylinder 5 in cooperation with the rotation preventing part 50 of the moving body 6. The same amount of movement of the moving body 6 in the rewinding direction is secured, and then the operation cylinder 3 is rotated in the rewinding direction and stopped. Rotated to a position, it may be obtained a body side assembly 40.

  On the other hand, in the filling member 1, the discharge port 1 c is closed with the seal 12 and inverted, and the filling region 1 x is filled with a predetermined amount of the filling material L and there is no space in the tip of the filling member 1. And Then, with respect to the filling member 1 filled with the filling L, the front end side of the main assembly 40 is extrapolated from above and the piston 7 is inserted into the filling member 1 while the filling member 1 is inserted into the main body cylinder 2. Installing.

  At this time, the inner circumferential surface of the filling member 1 is engaged with the main body cylinder 3 while being in sliding contact with the annular protrusion 7 c for ensuring the watertightness of the piston 7. At the time of this engagement, as shown in FIG. 1, the air vent groove 1i on the inner peripheral surface of the filling member 1 is positioned so as to cross the annular projection 7c of the piston 7 in the axial direction. Through 1i, the air on the filling side is extracted to the rear side satisfactorily.

  When the mounting of the filling member 1 is completed, as shown in FIG. 1, there is a slight space A between the filling L filled in the filling member 1 and the piston 7 inserted in the filling member 1. It is left. Here, the space A is formed on the front side of the entire surface of the piston 7. The space A is formed in such a structure that the filling member 1 filled with the filling L is assembled to the main assembly 40 and the piston 7 is inserted into the filling member 1. This is because if the gap between the first and second members is set to zero, the filler L may be pushed out by the piston 7 and appear from the filling member 1. In this embodiment, in order to avoid this, a space is used. A is provided.

  And finally, if the seal | sticker 12 is peeled off, the filling extrusion container 100 of the initial state shown in FIG. 1 will be obtained. The seal 12 is hygienic when peeled off after purchase by a user (consumer). In the initial state of the filler extruding container 100, the filling member 1 and the piston 7 are in sliding contact with each other and the piston 7 is pushed backward during the assembly, so that the positional relationship between the piston 7 and the moving body 6 is as shown in FIG. It is in the state shown in

  According to the filling extrusion container 100 configured as described above, as shown in FIG. 29, the filling member 1 filled with the filling L is inserted and attached to the front end side of the main assembly 40. Therefore, it is easy to assemble the filling material L after filling the filling member 1, and the filling material L is a filling region 1x between the inner side of the front end of the filling member 1 and the piston 7 of the main assembly 40. Fully satisfied.

  1, when the cap 10 is removed by the user and the main body cylinder 2 and the operation cylinder 3 are relatively rotated in the feeding direction which is the one direction described above. Then, the screwing action of the first screwing portion 8 constituted by the screwing projection 5e of the moving screw tube 5 and the female screw 4d of the screw tube 4 is activated, and the latter half part of the knurling 2a of the main body tube 2 and the moving screw tube. The moving screw cylinder 5 moves forward by cooperation with the rotation preventing portion 60 of the moving screw cylinder 5 constituted by the five protrusions 5c. At the same time, the screwing action of the second screwing portion 9 constituted by the female screw 5d of the moving screw cylinder 5 and the male screw 6b of the moving body 6 is activated, and the protrusion 3g of the shaft 3y of the operation cylinder 3 is actuated. And the moving body 6 advances by cooperation with the rotation prevention part 50 of the moving body 6 comprised from the protrusion 6f of the moving body 6. FIG. In other words, the moving body 6 advances along with the moving screw cylinder 5 and simultaneously advances alone.

  At this time, since the lead of the first screwing portion 8 is made larger than the lead of the second screwing portion 9, the moving screw cylinder 5 advances greatly, and the moving body 6 itself advances small. Therefore, the moving body 6 moves forward from the initial state position shown in FIG. 1 by the amount that the moving body 6 itself adds a small advance amount to the large advance amount of the moving screw cylinder 5, as shown in FIG. Further, since the lead of the first screwing portion 8 is made larger than the lead of the second screwing portion 9 in this way, the moving screw cylinder 5 follows the large lead of the first screwing portion 8. Move forward quickly.

  Then, when the piston 7 moves forward by a predetermined amount while sliding inside the filling member 1 from the initial state shown in FIG. 1, that is, the state in which the air vent groove 1 i opens air to release the air in the space A, the air in the space A As shown in FIG. 2, the space A is immediately lost, the ventilation of the air vent groove 1 i is closed, and the piston 7 and the filler L are placed inside the filler member 1. It is in the state which touched airtightly. If the space A remains, the piston 7 moves forward and compresses the air, which may cause a delay in the appearance of the filling L from the tip. However, in the present embodiment, as described above, The space A is immediately lost by the advance.

  Then, when the moving screw cylinder 5 quickly advances in this way, as shown in FIG. 2, the front end surface of the spring portion 5b of the moving screw cylinder 5 comes into contact with the rear end surface of the filling member 1, and the main body cylinder 2 and the operation cylinder 3 As the compression spring 5f of the spring portion 5b of the moving screw cylinder 5 is compressed and accumulates the urging force, the main body portion 5a of the moving screw cylinder 5 advances and the screw of the moving screw cylinder 5 moves forward. The mating protrusion 5e is disengaged from the tip 4f (see FIG. 13) of the female screw 4d of the screw cylinder 4, and the screwing of the first screwing portion 8 is released.

  In the unscrewed state, the main body portion 5a of the moving screw cylinder 5 is urged rearward by the urging force of the compression spring 5f of the moving screw cylinder 5. Accordingly, when the relative rotation of the main body cylinder 2 and the operation cylinder 3 in the feeding direction is further continued, the screwing protrusion 5e of the main body portion 5a of the moving screw cylinder 5 biased rearward is connected to the female cylinder 4 in the screw cylinder 4. The screw 4d enters the tip 4f adjacent to the rotation direction, and the first screwing portion 8 is screwed back. When the relative rotation of the main body cylinder 2 and the operation cylinder 3 in the extending direction is further continued, the main body portion 5a of the moving screw cylinder 5 moves forward while the compression spring 5f of the moving screw cylinder 5 is compressed, and the moving screw The threaded projection 5e of the cylinder 5 is disengaged from the tip 4f of the female thread 4d of the threaded cylinder 4 and the threading is released, and the threading is restored by the relative rotation in the same direction. The screw release and screw return of the part 8 are repeated.

  Here, a sliding resistance is generated between the piston 7 attached to the moving body 6 and the filling region 1x (inner peripheral surface of the filling member 1), and this sliding resistance compresses the moving screw cylinder 5. When the first screwing portion 8 is screwed back by the biasing force of the spring 5f, it becomes a resistance of the biasing force of the compression spring 5f acting on the moving body 6 via the second screwing portion 9, and in some cases, Although the first screwing portion 8 may not be screwed back by the urging force of the compression spring 5f, in the present embodiment, as described above, the moving body 6 moves in the axial direction with respect to the piston 7 by a predetermined amount. It is possible.

  That is, the moving body 6 is urged rearward from the position shown in FIG. 20 via the second screwing portion 9 by releasing the screwing of the first screwing portion 8 and the biasing force of the compression spring 5f. Then, as shown in FIG. 21, it moves rearward with respect to the piston 7 without receiving the sliding resistance between the piston 7 and the filling region 1x, and the tip surface of the annular groove 6d of the moving body 6 is moved to the piston 7. The first screwing portion 8 is screwed back at a position where it comes into contact with the root on the tip side of the annular protrusion 7b. When the main body portion 5a of the moving screw cylinder 5 moves forward while the compression spring 5f of the moving screw cylinder 5 is compressed by the further relative rotation of the main body cylinder 2 and the operation cylinder 3 in the extending direction, the second screwing portion The moving body 5 moves forward through 9 and is brought into a state shown in FIG. 20, and the screwing of the first screwing portion 8 is released. In this way, the moving body 6 moves back and forth within a short range in the predetermined axial direction shown in FIGS. 20 and 21 with respect to the piston 7 without receiving sliding resistance between the piston 7 and the filling region 1x. The first screwing part 8 is screwed and released, and the screwing is returned and the first screwing part 8 is smoothly and satisfactorily returned.

  Then, the screwing action of the first screwing portion 8 works in this way, the moving screw cylinder 5 moves forward by a predetermined amount and reaches the forward limit, and the relative rotation of the main body cylinder 2 and the operation cylinder 3 in the feeding direction is performed. In a state where the screw release and screw return of the first screwing part 8 are repeated (the screwing action of the first screwing part 8 is not substantially activated). Only the screwing action of the second screwing part 9 works, and only the moving body 6 moves forward as shown in FIG. 3 by cooperation with the rotation preventing part 50 of the moving body 6. When the moving body 6 alone moves forward, as described above, the moving body 6 is short in the predetermined axial direction by repeatedly releasing the screwing of the first screwing portion 8 and returning the screwing. Move forward and back repeatedly within the range.

  Here, in a state where the moving screw cylinder 5 reaches the advance limit and only the moving body 6 moves forward, as described above, the first screwing is performed by the relative rotation of the main body cylinder 2 and the operation cylinder 3 in the extending direction. Since the screw release and the screw return of the part 8 are repeated, this causes a click feeling, and the degree of relative rotation in the feed-out direction and the moving condition of the moving body 6 are suitably sensed by the user.

  Then, only the moving body 6 moves forward by the relative rotation accompanied by a click feeling in the feeding direction of the main body cylinder 2 and the operation cylinder 3, and the filler L is pushed out by the piston 7 at the tip and appears through the discharge port 1c.

  At this time, since the lead of the second screwing portion 9 is made smaller than the lead of the first screwing portion 8, the moving body 6 is slowly extended according to the small lead of the second screwing portion 9. The filled material L is appropriately discharged from the discharge port 1c of the filling member 1 and put into use.

  Further, as described above, due to the quick advancement of the moving screw cylinder 5, the space A is eliminated as shown in FIG. 2, and the space between the inside of the tip of the filling member 1 and the piston 7 as shown in FIG. Since the filling region 1x is filled with the filling material L without a gap, the filling material L is immediately discharged from the discharge port 1c by the advancement of only the moving body 6.

  Then, after the use, when the main body cylinder 2 and the operation cylinder 3 are relatively rotated in the retraction direction (the opposite direction to the extension direction) which is the other direction, the moving screw cylinder 5 urged rearward. The threaded projection 5e enters the tip 4f (see FIG. 13) of the female thread 4d of the threaded cylinder 4, and the first threaded part 8 is threaded and returned, so that the main body cylinder 2 and the operating cylinder 3 are moved back. When the relative rotation continues further, the screwing action of the first screwing part 8 operates without any trouble, and the moving screw cylinder 5 moves backward by cooperation with the rotation preventing part 60 of the moving screw cylinder 5. At the same time, the screwing action of the second screwing portion 9 is activated, and the moving body 6 moves backward by cooperation with the rotation preventing portion 50 of the moving body 6. In other words, the moving body 6 is retracted along with the moving screw cylinder 5 and is also retracted alone.

  At this time, since the lead of the first screwing portion 8 is made larger than the lead of the second screwing portion 9, the moving screw cylinder 5 is largely retracted, and the moving body 6 itself is retracted small. Therefore, the movable body 6 moves backward from the position shown in FIG. 3 by adding a small backward movement amount of the movable body 6 itself to the large backward movement amount of the moving screw cylinder 5. Further, since the lead of the first screwing portion 8 is made larger than the lead of the second screwing portion 9 in this way, the moving screw cylinder 5 follows the large lead of the first screwing portion 8. The mobile body 6 moves backward quickly, and the moving body 6 also moves backward with the moving screw cylinder 5.

  Due to the quick retreat of the moving screw cylinder 5 and the moving body 6 (piston 7), the filling material L is sucked into the filling region 1x from the discharge port 1c of the filling member 1, and as shown in FIG. A predetermined space B is immediately formed inside the discharge port 1c. Therefore, the filling L remaining on the outer surface 1a at the front end of the filling member 1 is reduced, which is economical.

  Then, due to the relative rotation of the main body cylinder 2 and the operation cylinder 3 in the retraction direction, the moving screw cylinder 5 is retracted by a predetermined amount (the moving screw cylinder 5 is retracted by the same amount as the advance amount), and the moving screw cylinder 5 The screw projection 5e reaches the rear end of the female screw 4d of the screw tube 4, and the rear end surface 5g of the spring portion 5b of the moving screw tube 5 is on the front end surface 4f of the screw tube 4 and the front end surface 3j of the main body portion 3x of the operation tube 3. When it comes into contact and reaches the retreat limit (see FIG. 1), the screwing action of the first screwing portion 8 stops and further relative rotation of the main body tube 2 and the operation tube 3 in the retraction direction stops. . That is, the main body cylinder 2 and the operation cylinder 3 cannot be further rotated relative to each other in the retraction direction, and the backward movement of the movable body 6 is also stopped.

  As described above, the movable body 6 at an arbitrary position advanced by a certain amount or more from the retreat limit by the relative rotation of the main body tube 2 and the operation tube 3 in the retraction direction does not retreat beyond a certain amount. Specifically, the moving body 6 has a small retraction amount of the moving body 6 itself when the moving screw cylinder 5 is retracted from the advancing limit to the retreating limit. It will not retreat beyond the amount added. Therefore, the relative rotation of the main body cylinder 2 and the operation cylinder 3 in the retraction direction prevents the movable body 6 from returning too much.

  Note that, for example, when the moving screw cylinder 5 at the forward limit is not retracted to the retreat limit due to the relative rotation of the main body cylinder 2 and the operation cylinder 3 in the retraction direction, specifically, in the state shown in FIG. In the case where the main body cylinder 2 and the operation cylinder 3 are not relatively rotated in the retraction direction by the user's operation, the moving body 6 is retracted by less than a certain amount (within a range not reaching the certain amount). In addition, a predetermined space B is similarly formed on the inner side of the discharge port 1c of the filling member 1, and the movable body 6 is retracted within a range not reaching a certain amount and does not return too much.

  When the movable body 6 at an arbitrary position advanced by the relative rotation of the main body cylinder 2 and the operation cylinder 3 in the retraction direction is retracted, the filling material filled in the filling region 1x Even if the air mixed in L and the filling L expands due to a change in temperature or pressure, leakage of the filling L from the discharge port 1c is caused by the predetermined space B provided inside the discharge port 1c. Is prevented.

  When the main body cylinder 2 and the operation cylinder 3 are rotated relative to each other in the extension direction again by the user in order to make the filler L into a use state from the state where the movable screw cylinder 5 and the movable body 6 are retreated in this state. In the same manner as described above, the screwing action of the first screwing portion 8 is activated, and the moving screw cylinder 5 moves forward by the cooperation with the rotation preventing portion 60 of the moving screw cylinder 5, and the second The screwing action of the screwing part 9 is activated, and the moving body 6 moves forward by cooperation with the rotation preventing part 50 of the moving body 6.

  At this time, the moving screw cylinder 5 quickly moves forward in accordance with the large lead of the first screwing portion 8, and the moving body 6 also moves quickly with the rapid advancement of the moving screw cylinder 5, so that the predetermined space B is immediately formed. Be lost. Moreover, since the returning of the moving body 6 is prevented as described above, it is prevented that the filling material L does not readily appear from the discharge port 1c. Thereafter, the same operation as described above is performed, and such an operation is repeated.

  Further, as shown in FIG. 5, when the piston 7 moves forward to the maximum by the relative rotation of the main body cylinder 2 and the operation cylinder 3 in the extending direction, the piston 7 comes into contact with the inner surface 1 b of the front end portion of the filling member 1. The filling L in the filling area 1x is almost used up.

  As described above, according to the filler extruding container 100 of this embodiment, when the main body cylinder 2 and the operation cylinder 3 are relatively rotated in the feeding direction which is one direction, the moving body 6 moves forward and is filled in the container. The filled material L is pushed out and emerges from the discharge port 1c, which is the opening at the tip of the container, and is in a use state. After use, the main body tube 2 and the operation tube 3 are in the other direction opposite to one direction. When the relative rotation is performed in a certain rewinding direction, the movable body 6 at an arbitrary position moved forward moves backward. For this reason, after use, even if the predetermined space B is formed inside the discharge port 1c at the front end of the container and the filler L and the air mixed into the filler L expand due to temperature change or pressure change, the container The predetermined space B provided on the inner side of the discharge port 1c at the front end prevents the filler L from leaking from the discharge port 1c, and the quality is improved. Further, when the main body cylinder 2 and the operation cylinder 3 are rotated relative to each other in the retraction direction, the movable body 6 at an arbitrary position advanced moves backward by a certain amount and stops, in other words, moves backward beyond a certain amount. Therefore, it is possible to prevent the mobile body 6 from returning too much and prevent the filling L from appearing from the discharge port 1c at the next use, thereby improving usability (ease of use).

  Further, when the main body cylinder 2 and the operation cylinder 3 are relatively rotated in the pay-out direction and the screwing of the first screwing part 8 is released, the first screwing part 8 is moved by the urging force of the compression spring 5f. Since it is configured to be screwed back, when the main body cylinder 2 and the operation cylinder 3 are relatively rotated in the retraction direction, the screwing action of the first screwing portion 8 works without hindrance and the moving body 6 moves backward. It is like that. Further, when the relative rotation in the feeding direction is continued, the screw release of the first screwing portion 8 and the screwing return by the compression spring 5f are repeated. The degree of relative rotation and the degree of movement of the moving body 6 are perceived by the user.

  Further, the movable body 6 has a male screw 6b which is one of the second screwing portions 9, and the female screw 5d of the moving screw cylinder 5 which is the other of the second screwing portions 9 is urged. The compression spring 5f is urged in the screwing return direction of the first screwing portion 8, and a piston 7 for sliding the inside of the filling region 1x and pushing out the filling material L is provided at the tip of the moving body 6. Since the movable body 6 is mounted and movable in the axial direction with respect to the piston 7 by a predetermined amount, the movable body 6 is filled with the piston 7 when the first screwing portion 8 is unscrewed. A predetermined amount is moved in the axial direction by the biasing force of the compression spring 5f without receiving a sliding resistance with respect to the region 1x, whereby the first screwing portion 8 is smoothly and satisfactorily returned to the screwing state. ing.

  Further, since the lead of the first screwing portion 8 is made larger than the lead of the second screwing portion 9, if the main body cylinder 2 and the operation cylinder 3 are relatively rotated in the feeding direction, the movement The body 6 quickly advances in accordance with the large (coarse) lead of the first threaded portion 8 and the predetermined space A and space B are immediately eliminated, and the relative rotation in the feeding direction is continued, so that the first threaded portion 8 When the screwing is released, the moving body 6 advances slowly according to the small (fine) lead of the second screwing part 9 and the filling material L appears from the discharge port 1c at the tip of the container. When the main body cylinder 2 and the operation cylinder 3 are rotated relative to each other in the retraction direction after use, the movable body 6 quickly retreats according to the large lead of the first screwing portion 8 so that the predetermined space B is formed. It is formed immediately, and as a result, usability (ease of use) is further improved.

  In addition, by making the lead of the first screwing portion 8 larger than the lead of the second screwing portion 9 in this way, the moving body 6 brought along with the moving screw cylinder 5 can be rapidly advanced and retracted. The discharge of the filler L by the advancement of only the moving body 6 is made moderately slow, but the lead of the first screwing portion 8 and the lead of the second screwing portion 9 are the same, Furthermore, the lead of the first screwing portion 8 can be made smaller than the lead of the second screwing portion 9.

  Further, when the mounting of the filling member 1 to the main assembly 40 is completed, there is a configuration in which there is a space A between the filling L filled in the filling member 1 and the piston 7 inserted into the filling member 1. The filling L does not appear reliably from the filling member 1.

  Moreover, since the air vent groove 1i which is a ventilation | gas_flowing part is provided in the filling member 1, the air of the said space A is escaped favorably through the air vent groove 1i.

  Moreover, in this embodiment, since it is the double spiral structure by the 1st, 2nd screwing parts 8 and 9, the advantage that a filling area | region length can be ensured, saving the axial direction length of the filling extrusion container 100. There is also.

  In addition, by making the filling member 1 transparent, it is possible to check the color of the filling L through the flange 1d of the filling member 1 with the cap 10 at the tip.

  30 to 34 are respective longitudinal sectional views showing states of the filling material extruding container according to the second embodiment of the present invention, FIG. 35 is a cutaway perspective view showing a main body cylinder, and FIGS. 36 and 37 are intermediate views. FIGS. 38 and 39 are diagrams showing a moving body, FIGS. 40 and 41 are diagrams showing a moving screw cylinder, and FIGS. 42 and 43 are diagrams showing a rotating member. 44 and 45 are each a diagram showing a screw cylinder, and FIG. 46 is a vertical perspective view showing a filling member.

  As shown in FIG. 30, a filling extrusion container 200 includes a cylindrical filling member 101 having both ends opened, a filling L filled in a filling region 101z inside the filling member 101, and a front portion thereof. A main body cylinder (main body) 103 that interpolates the rear portion of the filling member 101 and connects the filling member 101 so as to be relatively rotatable and cannot be detached in the axial direction is provided as an outer configuration, and the container front portion is constituted by the filling member 101. In addition, the main body cylinder 103 constitutes the rear portion of the container.

  The filling material extruding container 200 is internally connected to a screw cylinder 104 that can be rotated synchronously with the main body cylinder 103 and cannot be detached in the axial direction, and can be synchronously rotated with the filling member 101 and cannot be detached in the axial direction. The rotating member 110 is connected to the main body cylinder 103 so as to be synchronously rotatable and cannot be detached in the axial direction, and the rotating member 110 is elastically pressed in the axial direction and cannot be detached in the axial direction. A filling member 101 constituting the container front part and an operation cylinder 103 constituting the container rear part are engaged with the screw cylinder 104 via the first screwing part 108 and engaged with the screw cylinder 104 so as to be rotatable and axially movable. When it is relatively rotated in the one-way feeding direction, it moves forward, and when it moves forward to a predetermined forward limit, the forward movement stops, and the filling member 101 and the main body cylinder 103 move in the other direction opposite to one direction. The moving screw cylinder 105 is engaged with the main body cylinder 103 so as to be able to rotate synchronously and move in the axial direction while moving backward and retreating to a predetermined retreat limit. When the filling member 101 and the main body cylinder 103 are rotated relative to each other in one direction, they move forward along with the moving screw cylinder 105 and simultaneously move forward alone to move the moving screw. When the cylinder 105 reaches the forward limit and the filling member 101 and the main body cylinder 103 are further rotated relative to each other in the same direction, the cylinder 105 advances alone, and when the filling member 101 and the main body cylinder 103 are rotated relative to each other in the other direction, a moving screw cylinder. At the same time as retreating along with the moving body 105, the moving body 106 also retreats alone, and when the moving screw cylinder 105 reaches the retreating limit, the moving body 106 stops retreating together with the moving screw cylinder 105, and is attached to the distal end portion of the moving body 106. A piston (extrusion section) 7 to slide is inserted into the filling member 101 includes schematically a.

  As shown in FIG. 35, the main body cylinder 103 includes a main body portion 103x configured in a bottomed cylindrical shape, and a shaft body 103y erected at the center of the bottom portion of the main body portion 103x so as to face the front end side. It is set as the structure provided.

  The main body portion 103x is provided with an annular convex recess 103a for engaging the intermediate member 111 in the axial direction on the inner peripheral surface of the distal end portion thereof (with the convex concave portions aligned in the axial direction) 103a. A knurl 103b provided with a large number of uneven portions in the circumferential direction on the inner peripheral surface on the rear side and extending in a predetermined length in the axial direction is provided for engaging the intermediate member 111 in the rotational direction. Yes. Further, the main body 103x has a plurality of protrusions 103c arranged in parallel along the circumferential direction on the inner peripheral surface on the bottom side and extending from the bottom toward the tip side, and engages the screw cylinder 104 in the rotation direction.

  As shown in FIG. 30, the filling member 101 is inserted between the rotating member 110 and the piston 7 and the intermediate member 111 from the rear side, and the rear end surface is in contact with the flange portion 110 c of the rotating member 110, The portion 101b engages with the annular convex recess 110d of the rotating member 110 in the axial direction, and the protrusion 110e of the rotating member 110 engages with the knurl 101c in the rotating direction. It is mounted so that it cannot be detached, and is integrated with the rotating member 110. As described above, the rotating member 110 is prevented from being detached to the front side in the axial direction by the spring portion 111y of the intermediate member 111 integrated with the main body cylinder 103, and can be rotated synchronously with the moving screw cylinder 105. The moving screw cylinder 105 is screwed to the moving body 106 via the second screwing portion 109, and the moving body 106 can be rotated synchronously with the main body cylinder 103. It is attached to the cylinder 103 so that it can rotate and cannot be removed in the axial direction. Further, the piston 7 is inserted into the rear end portion of the filling member 101 so as to be in close contact with the filling member 101.

  The filling member 101 is protected by the cap 112 by detachably attaching the cap 112 to the intermediate member 111.

  Next, an example of an assembly procedure of the filling material extruding container 200 having such a configuration will be described with reference to FIG. First, the moving screw cylinder 105 is screwed into the moving body 106 to the initial position. Alternatively, it is forced to get over the thread and push it to the initial position. Next, the rotating member 110 is extrapolated to the moving screw cylinder 105 so that the protrusion 105 b of the moving screw cylinder 105 is engaged between the protrusions 110 f and 110 f of the rotating member 110, and then the piston 7 is attached to the moving body 106. Furthermore, the outer diameter large diameter portion 105 y of the moving screw cylinder 105 is inserted from the large diameter portion 104 x of the screw cylinder 104, and the female screw on the inner peripheral surface of the screw cylinder 104 is inserted into the screw projection 105 e of the outer peripheral surface of the moving screw cylinder 105. 104d is screwed and rotated to a position where it stops in the rewinding direction to obtain a temporary assembly.

  Next, the temporary assembly is inserted from the opening side of the main body cylinder 103, and the movable body 106 is engaged with the shaft 106d of the shaft body 103y of the main body cylinder 103 while engaging the protrusion 106f of the movable body 106 with the shaft body. The screw cylinder 104 is inserted into the main body cylinder 103 while the protrusion 104a of the screw cylinder 104 is engaged between the protrusions 103c and 103c of the main body cylinder 103. Next, the intermediate member 111 is inserted and attached to the main body cylinder 103, and the intermediate member 111 makes the screw member 104 unremovable to the front side in the axial direction through the rotating member 110 and the rotating member 110, thereby obtaining a main body side assembly. It is done.

  On the other hand, in the filling member 101, the filling member 101 is filled and filled with a predetermined amount of the filling material L in a state where the discharge port 101a at the tip is closed with a seal similar to that of the first embodiment and inverted. It is assumed that there is no space in the tip. Then, with respect to the filling member 101 filled with the filling material L, the front end side of the assembly on the main body side is extrapolated from above, and the piston 7 is inserted into the filling member 101 while being inserted into the main body cylinder 103 (intermediate member 111). The filling member 101 is attached. At this time, the inner circumferential surface of the filling member 101 is engaged with the main body cylinder 103 while being in sliding contact with the annular protrusion 7 c for ensuring the watertightness of the piston 7.

  At the completion of the mounting of the filling member 101, the air vent groove 101i on the inner peripheral surface of the filler member 101 is positioned so as to cross the annular protrusion 7c of the piston 7 in the axial direction, so that the air vent groove 101i passes through the air vent groove 101i. The air on the filling side is extracted well to the rear side.

  When the mounting of the filling member 101 is completed, as shown in FIG. 30, there is a slight space Y between the filling L filled in the filling member 101 and the piston 7 inserted into the filling member 101. It is left. Here, in the second embodiment, the space Y is formed only on the front side of the peripheral edge of the piston 7 because the air on the center front side of the piston 7 is removed. Such a space Y is formed, as in the first embodiment, in which the filling member 101 filled with the filling material L is assembled to the main assembly and the piston 7 is inserted into the filling member 101. This is because if the gap between the filling L and the piston 7 is set to 0, the filling L may be pushed out by the piston 7 and appear from the filling member 101.

  Then, when the seal is removed from the filler extrusion container obtained in this way, as shown in FIG. 30, an initial state of the filler extrusion container 200 having no space in the tip of the filling member 101 is obtained.

  30, when the cap 112 is removed by the user and the filling member 101 and the main body cylinder 103 are rotated relative to each other in the feeding direction, the first screw screw container 200 shown in FIG. The screwing action of the mating portion 108 is activated, and the moving screw cylinder 105 moves forward in cooperation with the rotation preventing portion 150. At the same time, the screwing action of the second screwing part 109 is activated, and the moving body 106 moves forward by cooperation with the rotation preventing part 150. That is, the moving body 106 advances along with the moving screw cylinder 105 and simultaneously advances alone.

  At this time, since the lead of the first screwing portion 108 is made larger than the lead of the second screwing portion 109, the moving screw cylinder 105 advances greatly, and the moving body 106 itself advances small. Accordingly, the moving body 106 moves forward from the initial position shown in FIG. 30 by adding a small advance amount of the moving body 106 itself to the large advance amount of the moving screw cylinder 105. Further, since the lead of the first screwing portion 108 is made larger than the lead of the second screwing portion 109 in this way, the moving screw cylinder 105 follows the lead of the first screwing portion 108. Move forward quickly.

  Then, from the initial state shown in FIG. 30, that is, the state where the air vent groove 101 i is opened to release the air in the space Y, the piston 7 moves forward by a predetermined amount while sliding inside the filling member 101 as described above. As shown in FIG. 31, the air in the space Y is released to the rear side through the air vent groove 101i, and the space Y is immediately eliminated, and the ventilation of the air vent groove 101i is closed. Is in an airtight state in the filling member 101.

  When the moving screw cylinder 105 quickly advances in this manner, the flange 105a of the moving screw cylinder 105 comes into contact with the rear end surface of the spring part 110y of the rotating member 110, and the filling member 101 and the main body cylinder 103 are moved in the feeding direction. According to the relative rotation, the spring portion 110y of the rotating member 110 is compressed and accumulates an urging force, and the moving screw cylinder 105 moves forward, and the screwing protrusion 105e of the moving screw cylinder 105 is disengaged from the tip of the female screw 104d of the screw cylinder 104. The screwing of the first screwing part 108 is released.

  In this unscrewed state, the moving screw cylinder 105 is urged rearward by the urging force of the spring portion 110y of the rotating member 110. Therefore, when the relative rotation of the filling member 101 and the main body cylinder 103 in the feeding direction is further continued, the screwing projection 105e of the moving screw cylinder 105 biased rearward is connected to the female screw 104d in the screw cylinder 104. The first screwing portion 108 is screwed and returned to the tip adjacent to the rotation direction. When the relative rotation of the filling member 101 and the main body cylinder 103 in the feeding direction is further continued, the moving screw cylinder 105 moves forward while the spring portion 110y of the rotating member 110 is compressed, and the moving screw cylinder 105 is screwed. The protrusion 105e is disengaged from the tip of the female screw 104d of the screw cylinder 104, and the screwing is released. Then, the screw 105 is restored by relative rotation in the same direction, and the screwing of the first screwing part 108 is released. And screwing return is repeated.

  Here, a sliding resistance is generated between the piston 7 attached to the moving body 106 and the inner peripheral surface of the filling member 101, and this sliding resistance is caused by the biasing force of the spring portion 110 y of the rotating member 110. When the first screwing part 108 is screwed back, it becomes a resistance of the urging force of the spring part 110y acting on the moving body 106 via the second screwing part 109, and in some cases, the spring part of the rotating member 110 Although the first screwing portion 108 may not be screwed back with the urging force of 110y, in this embodiment, as described above, the moving body 106 can move a predetermined amount in the axial direction with respect to the piston 7. Has been.

  That is, the moving body 106 is urged rearward via the second screwing portion 109 by the urging force of the spring portion 110y of the rotating member 110 when the screwing of the first screwing portion 108 is released. It moves rearward with respect to the piston 7 without receiving a sliding resistance between the piston 7 and the inner peripheral surface of the filling member 101, and the tip surface of the annular groove 106 d of the moving body 106 is formed on the annular protrusion 7 b of the piston 7. The first screwing portion 108 is screwed back at a position where it abuts on the base on the tip side. When the moving screw cylinder 105 moves forward while the spring portion 110y of the rotating member 110 is compressed by the further relative rotation of the filling member 101 and the main body cylinder 103 in the feeding direction, it moves through the second screwing portion 109. The body 106 moves forward and the screwing of the first screwing part 108 is released. As described above, the mobile body 106 does not receive the sliding resistance between the piston 7 and the inner peripheral surface of the filling member 101, and the mobile body 106 has a short range in the predetermined axial direction relative to the piston 7 (the annular groove portion of the mobile body 106. 106d), the first screwing portion 108 is smoothly and satisfactorily returned by screwing, and the first screwing portion 108 is repeatedly unscrewed and returned.

  Then, the screwing action of the first screwing part 108 works in this way, the moving screw cylinder 105 moves forward by a predetermined amount and reaches the advance limit, and the relative rotation of the filling member 101 and the main body cylinder 103 in the feeding direction is performed. In a state where the screw release and screw return of the first screwing portion 108 are repeated (the screwing action of the first screwing portion 108 is not substantially activated). Only the screwing action of the second screwing portion 109 works, and only the moving body 106 moves forward as shown in FIG. 32 by cooperation with the rotation preventing portion 150 of the moving body 106. When the moving body 106 alone moves forward, as described above, the moving body 106 is short in the predetermined axial direction by repeatedly releasing the screwing of the first screwing portion 108 and returning the screwing. Move forward and back repeatedly within the range.

  Here, in the state where the moving screw cylinder 105 reaches the advance limit and only the moving body 106 moves forward, as described above, the first screwing is performed by the relative rotation of the filling member 101 and the main body cylinder 103 in the feeding direction. Since the screw release and screw return of the portion 108 are repeated, this causes a click feeling, and the degree of relative rotation in the feeding direction and the moving state of the moving body 106 are suitably detected by the user.

  Then, only the moving body 106 moves forward by the relative rotation accompanied by a click feeling in the feeding direction of the filling member 101 and the main body cylinder 103, and the filling material L is pushed out by the piston 7 at the tip and appears through the discharge port 101a.

  At this time, since the lead of the second screwing portion 109 is made smaller than the lead of the first screwing portion 108, the moving body 106 is slowly extended according to the small lead of the second screwing portion 109. The filled material L appropriately emerges from the discharge port 101a of the filling member 101 and is put into use.

  In addition, there is no space in the tip of the filling member 101 in the initial state, and the space Y is immediately lost as shown in FIG. Immediately emerges from the discharge port 101a.

  In the case of using from the initial state, the filler L appears through the discharge port 101a even if the moving screw cylinder 105 does not reach the forward limit.

  Then, after use, when the filling member 101 and the main body cylinder 103 are relatively rotated in the retraction direction, the screwing protrusion 105e of the moving screw cylinder 105 biased rearward is the female thread 104d of the screw cylinder 104. When the first screwing portion 108 is screwed back and the relative rotation of the filling member 101 and the operation tube 103 in the rewinding direction is further continued, the first screwing portion 108 is screwed. The operation is performed without any hindrance, and the moving screw cylinder 105 is moved backward by cooperation with the rotation preventing portion 150 of the moving body 106. At the same time, the screwing action of the second screwing part 109 is activated, and the moving body 106 moves backward by cooperation with the rotation preventing part 150 of the moving body 106.

  At this time, since the lead of the first screwing portion 108 is made larger than the lead of the second screwing portion 109, the moving screw cylinder 105 is largely retracted, and the moving body 106 is retracted small. Accordingly, the moving body 106 moves backward by an amount obtained by adding a small retraction amount of the moving body 106 itself to a large retraction amount of the moving screw cylinder 105. Further, since the lead of the first screwing portion 108 is made larger than the lead of the second screwing portion 109 in this way, the moving screw cylinder 105 follows the lead of the first screwing portion 108. The moving body 106 moves backward quickly, and the moving body 106 also moves back quickly with the moving screw cylinder 105.

  Due to the quick retraction of the moving screw cylinder 105 and the moving body 106 (piston 7), the filling material L is sucked into the filling region 101z from the discharge port 101c of the filling member 101 as shown in FIG. A predetermined space B1 is immediately formed inside the discharge port 101a.

  Then, the relative rotation of the filling member 101 and the main body cylinder 103 in the retraction direction causes the moving screw cylinder 105 to move backward by a predetermined amount (the moving screw cylinder 105 moves backward by the same amount as the forward movement amount). The screw projection 105e reaches the rear end of the female screw 104d of the screw tube 104, and the flange portion 105a of the moving screw tube 105 is an inner circumferential step surface between the large diameter portion 104x and the small diameter portion 104y of the screw tube 104 (see FIG. 45). When it comes into contact with 104e and reaches the retreat limit, the screwing action of the first screwing portion 108 stops, and further relative rotation of the filling member 101 and the main body cylinder 103 in the retraction direction stops. That is, the filling member 101 and the main body cylinder 103 cannot be further rotated relative to each other in the retraction direction, and the backward movement of the moving body 106 is also stopped. Thus, since the screwing action of the first screwing part 108 stops and the relative rotation stops, the rotational force is interfered by the screwing part 108, and even if it rotates further in the retraction direction and a large torque is applied. Torque is not applied to the relatively thin shaft body 103y and the shaft body 103y is not twisted.

  As described above, the relative movement of the filling member 101 and the main body cylinder 103 in the retraction direction causes the moving body 106 at an arbitrary position advanced by a certain amount or more from the retreat limit to not retreat beyond a certain amount. Specifically, the moving body 106 has a small retraction amount of the moving body 106 itself when the moving screw cylinder 105 retreats from the advance limit to the retreat limit to a predetermined amount that the move screw cylinder 105 retreats from the advance limit to the retreat limit. It will not retreat beyond the amount added. Therefore, the relative rotation of the filling member 101 and the main body cylinder 103 in the retraction direction prevents the moving body 106 from being returned too much.

  Note that, for example, when the moving screw cylinder 105 at the forward limit is not retracted to the backward limit due to the relative rotation of the filling member 101 and the main body cylinder 103 in the retraction direction, specifically, the filling member 101 and the main body cylinder 103 are Even if the moving body 106 is moved backward by less than a certain amount (within a range not reaching the certain amount), the moving body 106 is kept at a certain amount. It is retreating within the range not reached and not returning too much.

  When the movable body 106 at an arbitrary position advanced by the relative rotation of the filling member 101 and the main body cylinder 103 in the retraction direction is retracted, the filling material filled in the filling region 101z. Even if the air mixed in L and the filling L expands due to a change in temperature or pressure, leakage of the filling L from the discharge port 101a is caused by a predetermined space B1 provided inside the discharge port 101a. Is prevented.

  In this state, that is, from the state where the moving screw cylinder 105 and the moving body 106 are fed back, when the user again rotates the filling member 101 and the main body cylinder 103 relative to each other in the feeding direction in order to put the filling L into a use state. In the same manner as described above, the screwing action of the first screwing portion 108 is activated, and the moving screw cylinder 105 moves forward by the cooperation with the rotation preventing portion 150 of the moving screw cylinder 105, and the second The screwing action of the screwing part 109 is activated, and the moving body 106 moves forward by cooperation with the rotation preventing part 150 of the moving body 106.

  At this time, the moving screw cylinder 105 quickly moves forward according to the large lead of the first screwing portion 108, and the moving body 106 also moves quickly with the rapid advancement of the moving screw cylinder 105, so that the predetermined space B1 is immediately formed. Be lost. Moreover, since the mobile body 106 is prevented from returning too much as described above, it is possible to prevent the filling material L from appearing from the discharge port 101a. Thereafter, the same operation as described above is performed, and such an operation is repeated.

  Further, as shown in FIG. 34, when the piston 7 moves forward to the maximum by the relative rotation of the filling member 101 and the main body cylinder 103 in the extending direction, the piston 7 comes into contact with the inner surface 101 g of the front end portion of the filling member 101. The filling L in the filling area 101z is almost used up.

  Even if it exists in such a filler extrusion container 200 of 2nd embodiment, the effect similar to the filler extrusion container 100 of 1st embodiment can be acquired.

  Incidentally, in this second embodiment, even if the cap 112 and the main body cylinder 103 are relatively rotated with the cap 112 mounted, the moving body 106 does not advance and the filling material L does not leak. .

  In the first and second embodiments, the outer surfaces 1a and 101f of the tip portion of the filling member 1 and 101 are used as application portions. However, the tip portions (outer surfaces) 1a and 101f of the filling member 1 and 101 are, for example, A porous material such as urethane foam or a fine net-like material may be provided, which may be used as an application part, or fine hairs may be provided on the outer surfaces 1a and 101f as an application part, and the taper is tapered. A brush formed by bundling polyester fibers may be attached and this may be used as an application part, or an elastic body such as silicon rubber or thermoplastic elastomer may be used as an application part.

  By the way, when the above-mentioned filling material is a rod-shaped material, a container capable of feeding / rewinding this rod-shaped material is known. However, in such a filling material extrusion container, the same problem as described above, that is, The rod-shaped object is returned too much, and the rod-shaped object does not readily appear from the opening at the next use, and there is a problem that the usability is poor.

  Therefore, in the next third embodiment, a filler extrusion container in which such a problem is solved will be described with reference to FIGS. 47 to 51. 47 to 50 are longitudinal sectional views showing states of the filling material extruding container according to the third embodiment of the present invention, and FIG. 51 is a longitudinal perspective view showing the filling member.

  The filler extrusion container 300 of the third embodiment is different from the filler extrusion container 200 of the second embodiment in that the filler is a rod-like object M as described above, and the filling member 201 is replaced with the filling member 101. The other configuration is the same as that of the second embodiment.

  In addition, the rod-like material referred to herein includes various stick-shaped cosmetics including lipstick, lip gloss, eyeliner, eye color, eyebrow, lip liner, cheek color, concealer, beauty stick, hair color, etc. This refers to a rod-shaped core or the like for writing instruments, and includes relatively hard rods and rods that are very soft (semi-solid, soft-solid, soft, jelly, or gel). Moreover, a thin core with an outer diameter of 1 mm or less or a thick core with a diameter of 10 mm or more may be used.

  As shown in FIGS. 47 and 51, the filling member 201 of the third embodiment is provided with an opening 201a in which the cylindrical hole of the filling member 101 of the second embodiment is opened at the tip. Accordingly, the large-diameter portion on the front side of the filling member 201 is a large-diameter portion 201x having an opening 201a at which the rod-like object M protrudes and disappears from the container. The other configuration of the filling member 201 is the same as that of the filling member 101 of the second embodiment, and the material, color, and the like are the same as those described in the second embodiment.

  And when filling the rod-like object M into the filling member 201 having such a configuration, a predetermined amount of the molten rod-like object is filled inside with the opening 201a at the tip of the filling member 201 closed and sealed up. What is necessary is just to cool and solidify in the state where there is no space in the front-end | tip of the filling member 201 by discharging from a nozzle and filling in the middle from the front-end | tip of the filling member 201 to a rear end. In addition, the internal shape of the cap 112 can be changed and can also be used as a seal member.

  The assembly procedure of the container is the same as that of the second embodiment. In the obtained filler extrusion container 300, the rod-like object M filled in the filling member 201 and the piston 7 inserted in the filling member 201 are used. Between these, a space Z similar to that of the first embodiment is formed. This space Z is used to prevent the stick M from being pushed out by the piston 7 and appearing from the filling member 201 when the filling member 201 filled with the stick M is attached to the main assembly. Needless to say, it is provided.

  Next, the operation of the filler extrusion container 300 will be briefly described. 47, when the cap 112 is removed by the user and the filling member 201 and the main body cylinder 103 are relatively rotated in the feeding direction, the first threaded portion 108 is operated, and the moving screw cylinder 105 is advanced largely (rapidly) in cooperation with the rotation stopper 150, and at the same time, the screwing action of the second screw 109 is operated, Due to the cooperation with the rotation stopper 150, the moving body 106 advances small (slowly).

  Then, from the initial state shown in FIG. 47, that is, the state where the air vent groove 101i is opened to release the air in the space Z, the piston 7 moves forward by a predetermined amount while sliding inside the filling member 201 as described above. As shown in FIG. 48, the air in the space Z is released to the rear side through the air vent groove 101i, and the space Z is immediately eliminated and the ventilation of the air vent groove 101i is closed, so that the filling region 201z of the filling member 201 is closed. The rod-like object M filled in the piston 7 and the piston 7 are in an airtight state in the filling member 201.

  Thereafter, when the relative rotation of the filling member 201 and the main body cylinder 103 in the feeding direction is continued, the moving body 106 and the moving screw cylinder 105 advance, and the moving screw cylinder 105 reaches the forward limit. The unscrewing and unscrewing operation of one screwing portion 108 and the reciprocating operation within a short axial range with respect to the piston 7 of the moving body 106 are the same as in the second embodiment. Then, when the relative rotation is continued in a state where the moving screw cylinder 105 reaches the advance limit, only the second screwing portion 109 is engaged, and only the moving body 106 moves forward slowly. Similar to the embodiment, a click feeling is generated by repeatedly releasing the screwing and screwing of the first screwing portion 108, and the rod-like object M is slowly pushed out by the piston 7 at the tip by the relative rotation accompanied by the clicking feeling. Appropriately appears through 201a and is put into use.

  Then, after use, when the filling member 201 and the main body cylinder 103 are relatively rotated in the rewinding direction, the first screwing portion 108 is screwed and returned as in the second embodiment. The screwing action of the screwing part 108 is activated and the screw cylinder 105 is quickly retracted. At the same time, the screwing action of the second screwing part 9 is actuated and the moving body 106 is slowly retracted (see FIG. 49). ).

  When the moving screw cylinder 5 and the moving body 6 retreat in this way, as described above, the space Z is eliminated, and the piston 7 and the rod-like object M are in an airtight contact state in the filling member 201. The rod-like object M is pulled back and retracted in the filling member 201 as the piston 7 is retracted by the pressure reducing action (the action of maintaining a sealed state) in the filling member 201. In addition, when the rod-like object M is a soft or gel-like rod-like object, for example, the rod-like object M is easily brought into close contact with the filling member 201, which is convenient for moving the rod-like object M backward.

  Then, the relative rotation of the filling member 201 and the main body cylinder 103 in the retraction direction causes the moving screw cylinder 105 to move backward by a predetermined amount (the moving screw cylinder 105 moves backward by the same amount as the forward movement amount). Is reached, the screwing action of the first screwing portion 108 stops, and further relative rotation between the filling member 201 and the main body cylinder 103 in the retraction direction stops, and the filling member 201 and the main body The cylinder 103 can no longer be relatively rotated in the retraction direction, and the backward movement of the moving body 106 is also stopped.

  That is, due to the relative rotation of the filling member 201 and the main body cylinder 103 in the retraction direction, the moving body 106 at an arbitrary position advanced by a certain amount or more from the retreat limit does not retreat beyond the certain amount, and the moving body 106 is prevented from returning too much.

  From this state, when the user again rotates the filling member 201 and the main body cylinder 103 in the feeding direction in order to put the rod-like object M into a use state, the first screwing is performed as described above. The screwing action of the portion 108 is activated, and the moving screw cylinder 105 is quickly advanced by the cooperation with the rotation preventing portion 150, and the screwing action of the second screwing portion 109 is activated to As a result, the moving body 106 moves forward slowly.

  At this time, as described above, since the moving body 106 is prevented from returning too much, it is prevented that the rod-like object M does not readily appear from the opening 201a. Thereafter, the same operation as described above is performed, and such an operation is repeated.

  As shown in FIG. 50, when the piston 7 advances to the maximum by the relative rotation of the filling member 201 and the main body cylinder 103 in the feed-out direction, the rod-like object M is almost used up.

  Even in such a filling extrusion container 300 of the third embodiment, the piston 7 is retreated by relative rotation in the retraction direction after use, and a predetermined space B1 is formed inside the container front end. Except for the effect that the leakage of the filler is prevented, the same effect as the filler extrusion container 200 of the second embodiment can be obtained.

  In addition, according to the third embodiment, since only the cylindrical filling member 201 is filled with the rod-like object M, the thickness of the filling member 201 is relatively uniform and the radial thickness of the rod-like object M is the axis. The temperature condition is constant along the direction, and it is possible to stabilize the temperature conditions from filling the molten rod-like material to solidifying.

  In addition, according to the third embodiment, since the filling member 201 filled with the rod-like material M is assembled to the main assembly, the soft semi-solid rod-like material, the thin and brittle rod-like material, the soft or gel-like material are used. Even if it is a rod-shaped object, the filling member 201 can be safely protected.

  The configuration of the third embodiment, that is, the configuration using the filling member 201 filled with the rod-like material M as the rod-like material M is the same as that of the filler extrusion container 100 of the first embodiment. Applicable to.

  Incidentally, the inner circumferential surface of the filling member 201 is gradually tapered (tapered shape) as it goes to the distal end side, or the opening 201a at the distal end of the filling member 201 is formed in the rear cylindrical hole (the tubular hole of the filling member 201). If it is made narrower, a particularly soft rod-shaped object can be held, and even if there is an external impact during storage, the rod-shaped object M is prevented from falling off and is safely held. Further, when the opening 201a at the tip of the filling member 201 is narrowed in this way, the solidified rod-like object M is pushed out by the piston 7 while narrowing the narrow opening 201a, so that the composition collapses and becomes soft, and a moderate usability. It becomes.

  The present invention has been specifically described above based on the embodiment. However, the present invention is not limited to the above embodiment. For example, in the above embodiment, the compression springs 5f and 110y are used as the urging means. However, for example, it is possible to use a tension spring by changing the arrangement, and it is also possible to use a biasing means other than the spring.

  Further, the structure for releasing the air in the spaces A, Y, Z is not limited to the air vent grooves 1i, 101i provided in the filling members 1, 101, 201. Any ventilation section for releasing the Z air may be used. As such a ventilation part, for example, an air vent hole that connects the inside and the outside of the filling members 1, 101, 201, an air vent groove provided outside the piston 7, and the packing L, M side of the piston 7 May be an air vent hole or the like that communicates with the moving body 6, 106 side, or a simple step inside the filling members 1, 101, 201 (the inner peripheral surface on the rear end side from the inner peripheral surface on the front end side). It is also possible to escape air by increasing the level).

  Further, the spaces A, Y, and Z formed between the piston 7 and the fillers L and M when the mounting of the filling members 1, 101, and 201 are completed are the entire surfaces of the piston 7 as in the first and third embodiments. May be formed only on the front side of the peripheral edge of the piston 7 as in the second embodiment. Further, when the mounting of the filling members 1, 101, 201 is completed, there is a case where all of the air escapes through the ventilation portion and the spaces A, Y, Z are not formed.

  In the first to third embodiments, as described above, the relative rotation operation in which the piston 7 is moved forward by a predetermined amount to release the air in the spaces A, Y, and Z to eliminate the spaces A, Y, and Z is performed by the user. May be performed after purchase, or may be performed at the factory after the assembly of the filling extrusion containers 100, 200, and 300.

  Further, in the above-described embodiment, the male screw and the female screw may function in the same manner as the screw thread, such as a group of protrusions arranged intermittently or a group of protrusions arranged spirally and intermittently. Also, the screw projection may be a continuous screw thread.
