  By the way, in order to advance and retract the sliding shaft in the axial direction by relative rotation between the container body and the cartridge body, the sliding shaft that is housed in the container body so as to be able to advance and retract in the axial direction is rotated integrally with the cartridge body. There is a need. In the cosmetic container shown in Patent Document 1, when the knurled teeth that mesh with the knurled teeth are provided on the sliding shaft side as well as the knurled teeth are provided on the sliding shaft side, The knurled teeth on the sliding shaft and the knurled teeth on the sliding shaft side are meshed so that the cartridge body and the sliding shaft rotate integrally. In this case, when the cartridge body is assembled into the container body, It is necessary to align the knurling teeth and the knurling teeth on the sliding shaft side (meshing), and when the cartridge body is inserted from the opening of the container body, the knurling teeth do not mesh well. It is necessary to shift the container body slightly in the rotational direction and then insert it again. In poor operability, there is a problem that the present invention solves cents here.

The present invention has been devised in order to solve the above-mentioned problems. The invention of claim 1 is a cylindrical filling case filled with cosmetics, and is movable in the axial direction in the filling case. A cartridge body having an extrusion piece for moving cosmetics is incorporated into the container body so that the cartridge body can be freely inserted into and removed from the container body, and the extrusion bar built in the container body allows relative rotation of the cartridge body with respect to the container body. In the cartridge-type cosmetic container configured to move the extruding piece together by moving the screw in the axial direction based on the movement of the cosmetic, the extruding rod is in the direction around the axis with respect to the container main body. A claw portion provided on the cartridge body side in the screw groove engraved on the outer periphery of the push rod between the push rod and the cartridge body. Screw engaging means for engaging and disengaging the container body and moving the push rod in the axial direction by relative rotation between the container body and the cartridge body, and the push piece relative to the push rod The cartridge-type cosmetic container is provided with engaging means that can freely engage and disengage so as to move integrally in the axial direction.
The invention according to claim 2 is the cartridge type cosmetic container according to claim 1, wherein the integral movement in the retraction direction of the pushing piece by the pushing bar of the engaging means is temporarily released and then released. is there.

According to the first aspect of the present invention, when the cartridge body is assembled into the container body, the claw portion provided on the cartridge body side is inserted into the container body in the axial direction of the container body so that the screw groove is formed on the outer periphery of the push rod As a result, the push rod moves in the axial direction by the relative rotation of the claw portion with respect to the screw groove. For this reason, it is necessary to perform a complicated operation of aligning the knurled teeth so that the knurled teeth are engaged with each other, such as a structure in which the cartridge body and the push rod are integrally rotated in the axial direction by engaging the knurled teeth. As a result, the cartridge body can be easily incorporated into the container body.
By incorporating the cartridge body into the container main body according to the second aspect of the invention, the cartridge body is inserted in the container body axial direction and then rotated in a direction in which the cartridge body is slightly extended relative to the container main body. The claw portion engages with the screw groove and the pushing piece engages with the pushing rod, so that the cartridge body can be easily assembled into the container body, but the pushing rod is locked to the cartridge body. Thus, it is possible to obtain a cosmetic container in which the push-out rod moves forward and backward more stably.

However, the neck portion 10c and the trunk portion 10d are formed from the trunk portion 10d to the neck portion with the lower end opened. It has a hollow shape up to 10c, and at its upper end, an extrusion rod abutting portion 10e with which the leading portion 6a of the aforementioned extrusion rod 6 abuts is formed. On the outer peripheral surface of the boundary portion between the neck portion 10c and the body portion 10d, a sliding contact portion 10f that protrudes in a bowl shape toward the outer diameter side and has the same diameter as the lower end portion of the head portion 10a is formed. The slidable contact portion 10 f moves while being in slidable contact with the inner peripheral surface of the filling case 7. A space portion 10g is formed on the outer peripheral surface of the neck portion 10a, and an engagement projection piece 11d of the slider 11 described later moves in the space portion 10g in the axial direction.

  On the outer peripheral surface of the sliding contact portion 10f, a notch portion 10h that engages with an engaging claw 11c formed on the slider 11 is formed at a position facing each other in the circumferential direction. A tongue piece 10i that is cut out in a tongue-like shape (冂 -shape) is formed at the position of the body portion 10d immediately below the notch 10h, and on the inner peripheral surface side of the tongue piece 10i, The push rod engaging protrusion 10j that engages with the protrusion engaging groove 6b formed on the push rod 6 described above is formed, and is positioned slightly above the formation position of the push rod engaging protrusion 10j on the outer peripheral surface side. A sliding contact projection 10k is formed in sliding contact with the inner peripheral surface side of the slider 11.

The lower portion of the slider 11 is an annular body 11a. A ring groove 11b for mounting the second O-ring 13 is formed on the outer surface of the annular body 11a. Are formed with an inclined surface 11e and a small-diameter portion 11f for pressing the sliding contact projection 10k formed on the pushing piece 10. An engaging projection piece 11d formed with an engaging claw 11c for loosely engaging with the above-described notch 10h is located upward at positions facing each other on the upper surface of the annular body 11a. Protrusions are formed. The engaging claw 11c protrudes symmetrically outward in the circumferential direction of the annular body.
Since it is formed in this way, in a state where the slider 11 is attached to the pushing piece 10, the engaging claw 11 c is engaged with the notch 10 h in a loose-fitting manner, and the slider 11 is pushed out by the pushing piece 10. On the other hand, the engaging claw 11c is configured to be movable within a range in which the space portion 10g moves in the axial direction.

  Reference numeral 14 denotes a cap that covers the container body 1 and the cartridge body 5 in a hermetically sealed manner, which prevents the cosmetic from drying by covering the cap and prevents the entry of dust and the like. .

In the embodiment of the present invention configured as described, the process of assembling the cartridge body 5 filled with the cosmetic A will be described with reference to FIGS. Incidentally, since FIGS. 9 and 10 are filled with liquid cosmetics, they are illustrated as being upside down unlike other drawings.
The filling case 7 is filled with the cosmetic A. The cosmetic A to be filled here has a slightly larger amount of cosmetic than the prescribed amount in order to prevent the cosmetic A from being filled below the prescribed amount due to measurement error or the like. A is filled.

  As shown in FIG. 9A, first, the filling case 7 is filled with the cosmetic A in a state where the discharge hole 7ca is sealed by the sealing member 15. The filled case 7 is inserted from the opening side end of the filling case 7 into the middle cylinder 8 in which the operation claw body 9, the pushing piece 10, the slider 11, the first O-ring 12 and the second O-ring 13 are assembled together. Assemble the cartridge body 5. In this case, the operating claw body 9 has the leg portion 9c in a vertical state, the sliding projection 9d is separated from the large diameter portion 8e of the middle cylinder 8, and the middle cylinder 8 and the slider 11 are The upper end portion of the convex rib 8b of the cylinder 8 is in contact with the lower surface (upper surface in this figure) of the annular body 11a of the slider 11.

Then, as shown in FIG. 9B or FIG. 10A, when the middle cylinder 8 is inserted into the filling case 7, the tip of the extrusion piece 10 is immersed in the cosmetic A filled in the filling case 7. However, at this time, the first O-ring 12 is opposed to the large-diameter portion 7g with a gap, and as a result, at the beginning of inserting the middle cylinder 8, the cosmetic in the filling case As shown by an arrow X, the air at the top of A passes through the stepped portion 7f of the filling case 7, the gap and the groove 8c, and the space 10g side formed on the outer peripheral surface of the neck portion 10c of the pushing piece 10 It flows out to the.
Further, as shown in FIG. 9C or FIG. 10B, the pushing piece 10 is inserted into the filling case, and the first O-ring 12 is inserted until it is close to the stepped portion 7f. In the stage, all the air in the filling case flows out into the space portion 10g through the arrow X, and then a part of the cosmetic A further leaks out into the space portion 10g through the arrow X.

From this point, as shown in FIG. 9D or FIG. 10C, the first O-ring 12 passes over the stepped portion 7f to reach the small diameter portion 7h, and the upper end portion 8g of the middle cylinder 8 becomes the stepped portion 7f. When the middle cylinder 8 is inserted until it comes into contact with the first O-ring 12, the first O-ring 12 is elastically brought into contact with the small diameter portion 7 h and deformed, whereby the first O-ring 12 seals the filled cosmetic A. Adhere closely.
Here, the cosmetic material A leaked into the space portion 10g is the cosmetic material in the space portion 10g because the second O-ring 13 attached to the slider 11 is in close contact with the inner peripheral surface of the middle cylinder 8. A does not leak into the container body.

Next, the process of mounting the cartridge body 5 filled with the cosmetic A as described above to the container body 1 will be described.
First, as shown in FIG. 11, the push rod 6 has been moved (dropped) to the bottom 2a of the outer cylinder 2, and in this state, the cartridge case 5 is grasped by grasping the filling case 7 constituting the cartridge body 5. Is inserted toward the opening of the container body 1.
At this time, in the pushing piece 10, the lower surface of the head portion 10 a is in contact with the engaging claw 11 c of the slider 11, and the annular body 11 a of the slider 11 is in contact with the convex rib 8 b of the middle cylinder 8. The operating claw body 9 is in a state in which the leg portion 9c hangs down and the sliding projection 9d and the large diameter portion 8e of the middle cylinder 8 are separated from each other.

When the cartridge body 5 is inserted into the container body 1 in such a state, first, the lower end portion of the leg portion 9c of the operating claw body 9 comes into contact with the edge portion 3b as shown in FIG. Thus, the insertion of the operating claw body 9 beyond this is restricted. At this time, since the claw portion 9e of the operating claw body 9 has the lower tapered surface 9g, it is elastic to exceed the crest portion 6g of the spiral groove 6d formed in the push rod 6 by insertion. Deform. Due to this elastic deformation, the push rod 6 receives a force that pushes it downward. As a result, the bottom surface 6m of the push rod 6 bends toward the bottom surface 2a of the barrel 2, and this bend is the push rod as a bullet. It works as a force that lifts up. As a result, an upward force is generated in the spiral groove 6d due to a reaction force caused by a slight downward movement of the push rod, and the claw portion 9e can easily cross the crest 9e. To the valley 6h. And when the lower end part of the leg part 9c contact | abuts to the edge part 3b, it is the state which the nail | claw part 9e screwed together in the spiral groove 6d.
Incidentally, the function of the leg portion 6k as an ammunition can also be implemented by using an ammunition such as a coil spring or a leaf spring. Any device that can be easily matched can be used, and is not particularly limited to the present embodiment.

When further inserted from here, as shown in FIG. 12 (B), as described above, the movement of the actuating claw body 9 is restricted to the edge portion 3b, while the inner cylinder 8, the pushing piece 10, and the slider 11 are further When the lower end 8i of the middle cylinder 8 is inserted into the inner side of the container body and abuts against the stopper 3a, the insertion of the middle cylinder 8 in the container body axial direction is also restricted, and the container of the cartridge body 5 Further insertion into the main body 1 becomes impossible. In this state, the small-diameter portion 8d of the middle cylinder 8 presses the sliding projection 9d of the operating claw body 9 toward the pushing rod 6 side, and this is an embodiment of the screw locking means of the present invention. However, the claw portion 9e is in a state where it cannot be removed from the screwing of the spiral groove 6d.
Further, the leading portion 6a of the push rod 6 is in contact with the push rod abutting portion 10e of the push piece 10 so as to be slidable in the axial direction and integrally moved in the axial direction. By comprising, it becomes embodiment of the engaging means of this invention. From this state, further cartridge body 5 cannot be inserted, and thereby, care is taken so that the cartridge body is not excessively inserted into the container body.

  Then, as shown in FIG. 13 (A) from the state of FIG. 12 (B), when the cartridge body 5 is rotated with respect to the container main body 1 in a rotatable direction, the leg portion 9c is relative to the spiral groove 6d. The push rod 6 whose rotation is restricted in the circumferential direction by the groove 3c so as to move only in the axial direction with respect to the container main body 1 is rotated upward with respect to the container main body 1 together with the push piece 10. It will be. At this time, the push rod 6 and the push piece 10 are relatively rotated in the direction around the axis. Since the engaging claw 11c is movable in the vertical direction only during the space 10g of the pushing piece 10, the slider 11 remains without moving. As a result, the pushing piece 10 is moved. The sliding contact projection 10k, which is moved upward relative to the slider 11 and faces the inclined surface 11e, slides upward on the inclined surface 11e and moves to the position of the small diameter portion 11f.

Then, the push rod engaging projection 10j is pressed by the small diameter portion 11f, and the tongue piece 10i is elastically deformed inward, and as a result, as shown in FIG. The formed push rod engaging protrusion 10j is engaged with an engagement groove 6b formed in the push rod 6, whereby the push rod 6 and the push piece 10 are integrated.
Further, when the cartridge body 5 is rotated in the rotation direction with respect to the container body 1, the integrated push rod 6 and push piece 10 together with the slider 11 of the filling case 7 as shown in FIG. The liquid cosmetic A is discharged from the discharge hole 7c by moving toward the upper end portion 7a.

Next, the first removal process when the cartridge body 5 is forcibly removed (forced removal) from the state in which the cartridge body 5 is mounted on the container body 1 will be described.
When the cartridge body 5 is forcibly pulled out of the container body 1 from the state shown in FIG. 14A (the drawing in the same state as FIG. 13B), as shown in FIG. The relative movement of the pushing piece 10 and the slider 11 and the disengagement between the pushing bar 6 and the pushing piece 10 are thereby performed. That is, the slider 11 and the middle cylinder 8 move together with the filling case 7, but the pushing piece 10 is engaged with the slider 11 in a loose-fitting manner, so that the engaging claw 11c of the slider 11 pushes out. It does not move until it comes into contact with the lower surface of the head of the piece 10. At this time, the pushing piece 10 moves downward relative to the filling case 7, and the air Y flows in from the discharge hole 7c by the amount of the downward movement. Since the pushing piece 10 and the pushing bar 6 do not move with respect to the upward movement of the slider 11, the sliding contact protrusion 10k formed on the pushing piece 10 is inclined from the small diameter portion 11f formed on the slider 11 to the inclined surface 11e. Thus, the engagement with the engaging groove 6b of the push bar engaging projection 10j is released.

  On the other hand, since the operation claw body 9 is engaged with the spiral groove 6d, the movement claw is restricted and does not move together with the middle cylinder 8. Therefore, the middle cylinder 8 moves in a direction in which it rises with respect to the operation claw body 9. I will do it. As a result, the contact of the sliding projection 9d formed on the operating claw body 9 with the middle cylinder 8 moves from the small diameter portion 8d to the large diameter portion 8e via the inclined portion 8f. Expansion is possible, and the engagement of the claw portion 9e with the spiral groove 6d is released.

  When the cartridge body 5 is further pulled out from the container main body 1 from this state, since the push rod engaging projection 10j is separated from the engagement groove 6b, the engagement between the push rod 6 and the push piece 10 is released halfway. Although it is in a state, it is still in a partially caught state, so that the push rod 6 also moves upward following the upward movement of the push piece 10 and the slider 11. Further, the pressing state of the claw portion 9e against the spiral groove 6d is also released, and the engagement between the push rod 6 and the operating claw body 9 is also half released here, but it is still partially clawed. The part 9e is caught in the spiral groove 6d, and the push rod 6 is also moved upward as the operating claw body 9 moves upward.

  However, when the cartridge body 5 is pulled further upward, the upward movement of the push rod 6 is further increased by the flange portion 6f formed on the push rod 6 coming into contact with the stop portion 3a of the body tube 3. (See FIG. 15A), the cartridge body 5 and the push bar 6 are completely disengaged here. As a result, the push bar 6 falls toward the bottom surface 2a of the outer cylinder 2, and thus the cartridge body 5 is removed from the container body 1 (see FIG. 15B).

Next, a process for returning the cartridge body 5 to the container body 1 will be described.
When the cartridge body 5 is moved back with respect to the container body 1, the cartridge body 5 is mounted on the container body 1 as shown in FIG. 16A (showing the same state as FIG. 14A). Then, the cartridge body 5 is rotated in the direction of rewinding the container body 1.
Then, the pusher bar 6 and the pusher piece 10 engaged with the pusher bar 6 move downward, the sliding contact portion 10f of the pusher piece 10 abuts on the annular body 11a of the slider 11, and the pusher piece Ten further downward movements are restricted. At the same time, the sliding protrusion 10k of the pushing piece 10 moves from the small diameter portion 11f of the slider 11 to the inclined surface 11e, thereby releasing the engagement of the push bar engaging protrusion 10j with the engaging groove 6b ( FIG. 16B).

  When the operation is further repeated from this point, since the engagement of the push bar engaging projection 10j with the engagement groove 6b is released, the push bar 6 moves away from the push piece 10, but the claw of the operating claw body 9 Since the engagement of the portion 9e with the spiral groove 6d has not been released yet, only the push rod 6 moves downward by the relative rotation of the container body 1 with respect to the cartridge body 5 (see FIG. 17A), and the flange When the portion 6f comes into contact with the bottom surface 2a of the outer cylinder 2, further retreat is restricted (see FIG. 17B).

Furthermore, a process in the case where the cartridge body 5 that has been used and the cosmetic is less than the initial filling amount is attached to the container body will be described.
As shown in FIG. 18A, the used cartridge body 5 is in a state in which the pushing piece 10 and the operating claw body 9 are separated from each other. A is filled, and the space S is formed in the lower part and is located in the middle part of the filling case 7.
When such a cartridge body 5 is attached to the container body 1, as shown in FIG. 18 (B), the lower end portion of the leg portion 9c of the operating claw body 9 first comes into contact with the edge portion 3b. 9, the further insertion of the cartridge body 5 is restricted, and the lower end portion 8i of the middle cylinder 8 comes into contact with the stopper 3a of the body cylinder 3, so that the further insertion of the cartridge body 5 is restricted. At this time, since the claw portion 9e of the operating claw body 9 is the lower tapered surface 9g, the claw portion 9e is screwed into the spiral groove 6d formed in the push rod 6 when inserted. As shown in FIG. 12, it is the same as the case where the cartridge body 5 is mounted on the container body 1.
Then, when the operation claw body 9 engages with the push bar 6, the push bar 6 moves upward by the relative rotation of the container body 1 and the cartridge body 5, and is positioned at the intermediate portion of the filling case 7. The feeding is performed until the leading portion 6a of the pushing piece 6 abuts against the pushing rod abutting portion 10e of the pushing piece 10 (see FIGS. 19A and 19B).

  Here, until the top portion 6a of the push bar 6 comes into contact with the push bar abutting portion 10e of the push piece 10, there is no resistance to the moving operation by the feed, but when the push bar 6 comes into contact with the push piece 10, the feed is made. The user feels sliding resistance in the operation, and the user is made aware of it as a different sensation. Further, when the feeding operation is further performed from here, the tip end portion 6a of the pushing bar 6 pushes the pushing bar abutting portion 10e of the pushing piece 10, and the engaging claw 11c of the slider 11 is pushed by the pushing piece 10 accordingly. When the space portion 10g is relatively moved downward and comes into contact with the sliding contact portion 10f, the sliding contact projection 10k of the pushing piece 10 moves from the small diameter portion 11f of the slider 11 to the inclined surface 11e to push the pushing rod engaging projection 10j. Engages with the engaging groove 6 b of the push rod 6. This state is the same as FIG.

Thus, according to the present invention, when the cartridge body 5 is filled with the cosmetic, the air mixed in the filling case 7 can be extracted from the cosmetic filling portion and discharged from the discharge hole 7c. The cosmetic can be made into a high-quality liquid cosmetic that does not contain air, and a cosmetic container that provides such a liquid cosmetic.
Moreover, in order to extract air reliably, the liquid cosmetic is configured to leak a little from the cosmetic filling portion, but the extracted cosmetic is configured not to flow out to the container body. Therefore, the cosmetic material does not leak into the container body and harden, or when the cartridge body 5 is removed, the cosmetic material does not scatter and stain the surroundings.

  Further, when the cosmetic stored in the cartridge body 5 is liquid, but the cosmetic is used, the cartridge body 5 is pulled out from the container body opening toward the container body axial direction. Can be exchanged. At that time, the container body 1 and the cartridge body 5 are engaged by the engagement of the push rod 6 and the push piece 10 and the engagement of the operation claw body 9 and the push rod 6 at two locations. By releasing the engagement at the two locations, the push-out rod falls toward the bottom surface of the outer cylinder 2, so that it is not necessary to return the push-out rod to the lowest position when the cartridge body 5 is replaced.

  Further, when the cartridge body 5 is exchanged during use, the cartridge body 5 can be exchanged in a state where the pushing piece 10 incorporated in the cartridge body 5 is left in the position at the time of exchange. After the attachment, the first feeding until the pushing bar 6 comes into contact with the pushing piece 10 has nothing to come into contact with the leading portion 6a of the pushing bar 6, so there is no resistance to the feeding operation. After the stick 6 comes into contact with the pushing piece 10, the user feels a different sliding resistance, and the user may be aware that the cosmetic will soon be discharged from the discharge port 7c. it can. Accordingly, it is not necessary to carefully perform the feeding operation from the beginning, and it is only necessary to be aware of the discharge of the cosmetic material after feeling the sliding resistance, and the operability is excellent.

  In addition, according to the present invention, the container body is incorporated into the cartridge body by simply inserting the cartridge body in the container body axial direction so that the claw portion provided on the cartridge body side is formed in the screw groove formed on the outer periphery of the push rod. Since the push rod moves in the axial direction by the relative rotation of the claw portion with respect to the screw groove, the knurled teeth are engaged with each other so that the cartridge body and the push rod are integrated in the axial direction. There is no need to perform the complicated operation of aligning (tooth alignment) in order to mesh the knurled teeth like those configured to rotate, and the cartridge body can be easily incorporated into the container body. I can do it.

  Further, when assembling the cartridge body into the container body, the claw portion is inserted into the screw groove by inserting the cartridge body in the container body axial direction and then rotating the cartridge body slightly with respect to the container body. At the same time, the pushing piece engages with the pushing rod, so that the locking of the pushing rod with respect to the cartridge body becomes stable, and the forward and backward movement of the pushing rod becomes more stable.

  INDUSTRIAL APPLICABILITY The present invention can be used in the field of cartridge-type cosmetic storage containers for storing cosmetics such as lipsticks, nail polishes, and foundations.
