  The present invention relates to an extruding device for extruding a container.

  BACKGROUND ART Conventionally, there is known an extruding device for extruding a container housed in a housing member by a pushing member from the housing member in multiple steps. For example, in Patent Document 1, a tubular main body (hereinafter, referred to as “housing member”) that houses a fluid material (hereinafter, referred to as “housing member”) and a housing member are divided into a plurality of times from the housing member. A plunger for pushing out (hereinafter, referred to as "extruding member") is disclosed.

  The accommodating member has a cylindrical accommodating portion that accommodates the accommodating body, and a discharge portion that discharges the accommodating body. The pushing member has a cylindrical outer sleeve having an inner diameter larger than the outer diameter of the accommodating portion, and a pressing structure that is connected to the inner side of the outer sleeve and pushes out the accommodating body. When the outer sleeve is inserted into the outer side of the accommodating portion and the outer sleeve is pushed in, the pressing structure pushes the accommodating body in the accommodating portion toward the ejecting portion, whereby the accommodating body is ejected from the ejecting portion. .. The container is discharged so as to adhere to the inner surface of the toilet bowl, for example.

  The accommodating portion is formed with a plurality of click slots arranged along the central axis direction of the accommodating portion. The outer sleeve is formed with a plurality of notch tabs arranged along the central axis direction of the outer sleeve. Each notch tab is provided with a click pin protruding inward in the radial direction from the inner peripheral surface of the notch tab and having a shape engageable with the click slot. Engagement of the click pin and the click slot defines one pushing operation of the pushing member.

  An extruding member of an extruding device described in Patent Document 1 includes a pressing structure for extruding a container housed in a housing portion, and an outer sleeve having a click pin for defining one pushing operation of the extruding member. Since the outer sleeve and the outer sleeve overlap each other in the radial direction, the structure of the extrusion member is complicated.

  It is an object of the present invention to provide an extruding device capable of extruding a container in a plurality of times with a simple structure.

  As a means for solving the above-mentioned problems, the present invention is an extruding device capable of extruding a container in a plurality of times and capable of accommodating the container and discharging the container. A housing member, and an extruding member for extruding the housing body from the housing member in a plurality of steps, wherein the pushing member has a cylindrical outer peripheral surface and extrudes the housing body from the housing member. A plurality of push shafts having a possible shape, and a plurality of push shafts that are connected to parts of the push shaft portion that are separated from each other in the central axis direction of the push shaft portion and that can specify the pushing position of the push shaft portion with respect to the housing member. And a push position defining portion, each push position defining portion having a shape that bulges outward in a direction orthogonal to an axis orthogonal to the central axis of the extrusion shaft portion from the outer peripheral surface of the extrusion shaft portion. The accommodating member includes a bulge portion and has a shape that can be flexibly deformed to allow the bulge portion to be displaced inward in the direction orthogonal to the axis, and the accommodating member allows insertion of the extrusion shaft portion. A housing portion having a tubular inner peripheral surface for housing the housing body, and one end side of the housing portion in the central axis direction of the housing portion, the one end side of the housing portion from the other end side. A restriction portion that restricts the displacement of the extrusion shaft portion in the extrusion direction by contacting the bulging portion while allowing the insertion of the extrusion shaft portion when the extrusion shaft portion is displaced along the extrusion direction. And a discharge part that is connected to the other end side of the containing part in the central axis direction of the containing part and discharges the containing body, wherein the restricting part is in contact with the restricting part with the bulging part. With the relative displacement of the regulating portion and the pushing shaft portion from the state described above, the outer end portion of the bulging portion in the direction orthogonal to the axis is located until the inner side of the regulating portion in the axis orthogonal direction. There is provided an extruding instrument having a bulging portion pressing portion having a shape capable of pressing the bulging portion toward the inner side in the direction orthogonal to the axis.

  In the present invention, when the pushing shaft portion is pushed into the holding member along the pushing direction, the bulging portion of the pushing position defining portion connected to the pushing shaft portion comes into contact with the regulating portion and is pushed from the discharging portion. The body is exhaled. This completes one pushing operation. Then, with the relative displacement of the restricting portion and the pushing shaft portion from the state in which the bulging portion is in contact with the restricting portion, the bulging portion pressing portion is such that the outer end portion of the bulging portion in the direction orthogonal to the axis is more Also pushes the bulging portion toward the inside in the direction orthogonal to the axis until it is positioned inside the direction orthogonal to the axis, so that the next pushing operation of the pushing member becomes possible. By repeating the pushing operation in this manner, the container is pushed out of the ejection portion in a plurality of times. As described above, in the present extruding device, the push-in position defining portion capable of defining one push-in operation is connected to the push-out shaft portion for pushing out the container, and the restricting portion defines the push-in position defining portion in the direction orthogonal to the axis. Since the bulging portion pressing portion having a shape capable of being pressed inward in the direction is included, it is possible to push out the container in multiple times while simplifying the structure of the pushing member.

  In this case, each push-in position defining portion connects the bulging portion and the push-out shaft portion and is flexibly deformed so as to allow the bulging portion to be displaced inward in the axial orthogonal direction. Each of the bending pieces has an end on one side in the circumferential direction of the extruding shaft portion of the bending piece connected to the extruding shaft portion, and in the bending direction of the extruding shaft portion of the bending piece. The other end of the bending piece has a shape that is connected to the bulging portion, and the circumferential dimension of the pushing shaft portion of each bending piece is larger than the dimension of the pushing shaft portion of the bending piece in the central axis direction. Is also preferably set large.

  By doing this, while avoiding a significant increase in the size of the extrusion shaft portion in the central axis direction, disposing a plurality of bulging portions along the central axis direction of the extrusion shaft portion and It is possible to reduce the force required to press inward in the direction orthogonal to the axis. Specifically, since the circumferential dimension of each bending piece is set to be larger than the dimension of the bending piece in the central axis direction, when a plurality of bulging portions are arranged along the central axis direction, It is possible to avoid increasing the size of the extrusion shaft portion in the central axis direction, and since each bending piece has a shape that is connected to the extrusion shaft portion at one end side in the circumferential direction, each bending piece has one end in the central axis direction. As compared with the case where the flexible piece has a shape connected to the extrusion shaft portion, the dimension of the bending piece in the direction (circumferential direction) connecting the extrusion shaft portion and the bulge portion is secured to be large, that is, each bulge portion is It is possible to reduce the force required to displace inward in the direction orthogonal to the axis.

  Further, in this case, the bulge portion is connected to a tip end portion of the bending piece opposite to the base end portion on the side where the bending piece and the extrusion shaft portion are connected in the longitudinal direction of the bending piece. And a second projecting portion connected to a portion of the bending piece between the base end portion and the distal end portion, the extruding shaft portion of the first projecting portion. The amount of protrusion from the outer peripheral surface of the second protrusion is set to be greater than the amount of protrusion from the outer peripheral surface of the extrusion shaft portion of the second protrusion, and the bulging portion pressing portion is configured to have the first protrusion in the axial orthogonal direction. It is preferable that the protrusion has a shape capable of pressing the second protrusion toward the inside in the axis orthogonal direction until the outer end of the protrusion is located inside the regulation portion in the axis orthogonal direction.

  With this configuration, the pushing position can be effectively defined while suppressing the bending of the bending piece, that is, the increase of the bending stress generated at the boundary between the bending piece and the extrusion shaft portion. Specifically, a first protrusion having a relatively large amount of protrusion is formed at the distal end portion of the bending piece, that is, at a portion of the bending piece having the largest bending, and the first protrusion portion having a relatively large amount of protrusion is formed between the base end portion and the tip end portion of the bending piece. Since the second projecting portion having a relatively small projecting amount is formed at the portion of the bending piece, that is, the portion of the bending piece having less bending than the tip end portion, the entire bulging portion is formed in the direction orthogonal to the axial direction with respect to the restricting portion. While suppressing an increase in the bending of the bending piece necessary for displacing the inside of the ridge, the push-in position is ensured by effectively ensuring the contact area between the bulging part and the regulating part when the extrusion shaft part is displaced in the extrusion direction. Can be effectively defined.

  Specifically, the dimension of the bulging portion pressing portion in the push-out direction is set to a rear end portion of the push-out direction in the specific first protrusion and one rear side of the specific first protrusion in the push-out direction. It is set to be shorter than the distance between the first projecting portion located and the tip end portion in the extrusion direction, and the restriction portion is configured to move the extrusion shaft portion in the extrusion direction to cause the specific first portion to move. It is preferable to have a shape that retracts in the axial orthogonal direction from the specific first protrusion when the first protrusion that is one behind the protrusion contacts the regulation portion.

  With this configuration, the pressing of the specific first protruding portion by the bulging portion pressing portion is released before the first protruding portion located one rear of the specific first protruding portion contacts the regulation portion. Moreover, since the bending deformation of the bending piece is released when the first protruding portion located one rearward of the specific first protruding portion contacts the bulging portion, the bending piece after the pushing operation is completed. The creep deformation of is suppressed.

  Further, in the present invention, when the pushing shaft portion is displaced in a direction opposite to the pushing direction, an outer end portion of the first projecting portion in the direction orthogonal to the axis is more axial than the regulating portion. It is preferable to have a first protruding portion pressing portion having a shape capable of pressing the first protruding portion toward the inner side in the axis orthogonal direction until it is positioned inside the orthogonal direction.

  With this configuration, the pull-out operation for pulling the push-out member from the accommodating member becomes easy. Specifically, when the push-out shaft portion is pulled out from the inside of the accommodating portion in the direction opposite to the push-out direction, the first protruding portion pressing portion presses the first protruding portion inward in the axis orthogonal direction, so that the bending piece is deformed. It is flexibly deformed, whereby the first protruding portion is displaced to the inside of the regulating portion. Therefore, by pulling out the pushing member in the direction opposite to the pushing direction, the pushing member is pulled out.

  Specifically, each first protrusion preferably has a shape in which the amount of protrusion from the outer peripheral surface of the extrusion shaft gradually increases in the extrusion direction.

  By doing so, it becomes possible to more easily pull out the pushing member from the housing member. Specifically, each of the first protrusions has a shape in which the amount of protrusion from the outer peripheral surface of the extrusion shaft gradually increases in the extrusion direction. Therefore, when the extrusion member is pulled out from the accommodation member, the extrusion shaft The first protruding portion is gradually pressed by the first protruding portion pressing portion inward in the direction orthogonal to the axis as is displaced in the direction opposite to the pushing direction. That is, since the bending (drawing resistance) of the bending piece gradually increases as the pushing shaft portion is displaced in the direction opposite to the pushing direction, the pulling operation of the pushing member from the housing member becomes easy.

  In this case, it is preferable that each of the first protrusions has a shape in which the amount of protrusion from the outer peripheral surface of the extrusion shaft portion gradually decreases from one end side in the circumferential direction of the extrusion shaft portion toward the other end side. ..

  With this configuration, the contact area between the first protruding portion and the first protruding portion pressing portion at the time of the pulling-out operation of the pushing member is reduced, so that the pushing member can be pulled out from the housing member more easily.

  Further, in the present invention, the first protruding portion pressing portion gradually increases an inward displacement amount of the first protruding portion in the axial orthogonal direction as the pushing shaft portion is displaced in a direction opposite to the pushing direction. Therefore, it is preferable that the first protrusion has a shape capable of being pressed inward in the direction orthogonal to the axis.

  With this configuration, since the bending (drawing resistance) of the bending piece gradually increases as the pushing shaft portion is displaced in the direction opposite to the pushing direction, the pulling operation of the pushing member from the housing member becomes easy. ..

  Further, in the present invention, the pushing member includes a blocking portion that blocks an outer end portion of the first protruding portion in the axis orthogonal direction from reaching an inner side in the axis orthogonal direction with respect to an outer peripheral surface of the pushing shaft portion. It is preferable to further have.

  With this configuration, it is possible to suppress the breakage of the bending piece and increase the dimension of the bending piece in the longitudinal direction (the direction connecting the pushing shaft portion and the first protruding portion) to pull out the pushing member from the housing member. The pullout resistance can be reduced. Specifically, since the blocking portion prevents the first protruding portion from being completely recessed inward of the outer peripheral surface of the extrusion shaft portion in the direction orthogonal to the axis, this is the case when the longitudinal dimension of the bending piece is increased. However, the bending of the bending piece, that is, the increase of the bending stress generated at the boundary between the bending piece and the extrusion shaft portion is suppressed. Therefore, both the reduction of the pull-out resistance by increasing the longitudinal dimension of the bending piece and the suppression of the breakage of the bending piece by suppressing the increase of the bending stress generated at the boundary between the bending piece and the extrusion shaft portion are compatible. be able to.

  Further, in the present invention, the extruding member further has a raised portion having a shape projecting from an outer peripheral surface of the extruding shaft portion toward an outer side in the axial orthogonal direction, and the restricting portion is fitted with the raised portion. The protrusion has a recess having a shape capable of fitting, and the protrusion has a shape extending along the extrusion direction so as to continue to be fitted in the recess when the extrusion shaft is displaced in the extrusion direction. Is preferred.

  With this configuration, the pushing member is pushed along the pushing direction with the raised portion fitted in the concave portion, so that the pushing posture of the pushing member is stable.

  Further, in the present invention, of the plurality of bulging portions, the bulging portion located closest to the tip end in the pushing direction and the bulging portion located one rear side of the bulging portion in the pushing direction It is preferable that the distance is set to be larger than the distance in the extrusion direction between the other bulging portions of the plurality of bulging portions excluding the bulging portion located closest to the tip end side.

  By doing so, the amount of the container pushed out from the containing member by the first pushing operation becomes larger than the amount of the containing body pushed out from the containing member by the pushing operation after the first pushing operation, so that It is possible to prevent the amount of extrusion by the first (first) pushing operation from becoming smaller than the amount of extrusion by the second and subsequent pushing operations due to a slight variation in the filling amount of the container. Therefore, the pushing amount of the container at each pushing operation is ensured to be a predetermined amount or more.

The housing member 100 has a shape capable of housing the housing 400 (see FIG. 21) and discharging the housing 400. The push-out member 200 has a shape that allows the container 400 housed in the housing member 100 to be pushed out of the housing member 100 in multiple steps.

  In this embodiment, the accommodating member 100 is accommodated in the accommodating member 100 as the accommodating body 400, which is fluid and adheres to the adherend surface S (see FIGS. 21 and 22) such as the inner surface of the toilet bowl. There is. Specifically, the pressure-sensitive adhesive body 400 has gel strength capable of adhering to the inner surface of the toilet bowl (preferably about 200 to 2000 mN at 25° C.). The gel strength is measured by a constant depth measuring method using a rheometer (CR-500DX, manufactured by Sun Kagaku Co., Ltd., RHEO DATA ANALYZER for win as data analysis software). As a measuring method, the diameter of the adapter is 20 mm, the penetration speed is 60 mm/min, the set distance (penetration depth) is 20 mm, and 50 g of the sample is put in a mayonnaise bottle (M-70 manufactured by Kashiwa Glass Co., Ltd.). It is measured after 24 hours. The maximum load measured at this time is the gel strength. The adhesive body 400 contains a chemical containing an aroma component, a cleaning component, and the like. However, the accommodation member 100 may accommodate, as the accommodation body 400, something different from the adhesive body 400 such as food or cosmetics.

  FIG. 2 shows the adhesive cartridge 20. The adhesive body cartridge 20 includes a housing member 100, a housing body 400 (adhesive body 400) housed in the housing member 100, and a cap 500 detachably attachable to the housing member 100. .. In addition, in FIG. 2, the illustration of the container 400 is omitted.

  In this pushing tool, when all the containing bodies 400 have been pushed out from the housing member 100 by the pushing member 200, the housing member 100 is discarded, but the pushing member 200 can be reused. That is, after the use of the pressure-sensitive adhesive body cartridge 20 including the containing body 400 and the containing member 100 is completed (after the whole containing body 400 is pushed out from the containing member 100), the push-out member 200 is used when another adhesive body cartridge 20 is used. Can be used. In addition, as shown in FIG. 3, the present extruding device can be stored upright on the mounting table 300 during use.

  The housing member 100 has a housing portion 110, a regulating portion 120, a discharge portion 160, and a plug member 180.

  The housing portion 110 houses the housing body 400. In the present embodiment, the housing section 110 is formed in a cylindrical shape. The accommodating portion 110 has a connecting portion 111 that is formed on one end side (upper side in FIG. 4) in the central axis direction (upward and downward direction in FIG. 4) of the accommodating portion 110 and that connects the restricting portion 120. .. The connection part 111 is formed in a shape projecting to the one end side from a part other than the connection part 111 of the part on the one end side of the housing part 110.

  The restriction part 120 restricts (limits) the insertion posture of the pushing member 200 into the accommodation part 110. The restriction part 120 is connected to the connection part 111 of the housing part 110. Details of the restriction unit 120 will be described later.

  The ejection part 160 is a part for ejecting the container 400 housed in the housing part 110. The discharge part 160 is connected to a part of the accommodation part 110 on the other end side (lower side in FIG. 4) in the central axis direction of the accommodation part 110. The ejection unit 160 is various as an adhering member 450 (see FIG. 23) formed by adhering the container 400 ejected from the ejecting unit 160 to the adherend surface S (see FIGS. 21 and 22). It has a shape that enables the formation of objects having different outer shapes. The ejection unit 160 has a shape that ejects the container 400 extruded along the extrusion direction along the ejection direction when the ejection unit 160 is in contact with the adherend surface S. Here, the pushing direction refers to a direction (downward in FIG. 4) from the one end side to the other end side of the accommodating section 110 with respect to the central axis direction of the accommodating section 110, and the ejection direction is the position inside the ejecting section 160. The containing body 400 indicates the direction on the adherend surface S toward the outside of the ejection portion 160. As shown in FIGS. 7 to 9, the discharge section 160 has a partition section 161, a connecting section 162, and a plurality of gap forming sections 163.

  The partition part 161 partitions the outlet for allowing the container 400 to flow out toward the attached surface S along the extrusion direction. Specifically, the partition portion 161 has an inner peripheral surface that surrounds the outflow port. In the present embodiment, the inner diameter of this inner peripheral surface is set smaller than the inner diameter of the housing portion 110.

  The connecting portion 162 connects the distal end portion of the housing portion 110 in the pushing direction and the partition portion 161. As shown in FIG. 9, the connecting portion 162 is formed in a shape in which the diameter of the inner peripheral surface of the connecting portion 162 gradually decreases in the pushing direction.

  The plurality of gap forming portions 163 are connected to the tip end portion of the connecting portion 162 in the extrusion direction. As shown in FIG. 8, the plurality of gap forming portions 163 are arranged so as to be arranged intermittently along a circumferential direction centered on an axis O (an axis passing through the center of the partition 161) parallel to the extrusion direction. ing. In this embodiment, the six gap forming portions 163 are arranged at equal intervals along the circumferential direction. However, the number of gap forming portions 163 is not limited to this. Each gap forming portion 163 has a shape extending from the tip end portion of the connecting portion 162 in the pushing direction toward the pushing direction.

  When the container 400 is discharged on the adhered surface S along the ejection direction, the extruded tips 164 of the plurality of gap forming portions 163 are brought into contact with the adhered surface S. That is, in the present embodiment, the tip 164 of each gap forming portion 163 constitutes the “contact portion 164” that abuts on the adherend surface S. More specifically, the tip end 164 of each gap forming portion 163 is a flat surface capable of making surface contact with the adherend surface S, and constitutes a “contact surface”. As shown in FIGS. 21 and 22, these contact surfaces are formed on the same plane. These gap forming portions 163 are in contact with each other between the gap forming portions 163 that are adjacent to each other in the circumferential direction, and the contact portion 164 (contact surface) that is the tip of the gap forming portion 163 is in contact with the adherend surface S. In this state, the container 400 extruded from the accommodating portion 110 along the pushing direction is ejected so as to spread on the adherend surface S along the ejection direction outward from the contact portion 164 (contact surface). It has a shape that forms a gap C having a shape that allows it to be crushed.

  Each gap forming portion 163 has an inner side surface 163a formed inside the direction parallel to the ejection direction (direction connecting the axis O and the gap forming portion 163 in FIG. 8) and an outside formed outside the same direction. It has a side surface 163b and a facing surface 163c that faces the gap forming portion 163 that is adjacent in the circumferential direction.

  The inner side surface 163a is set in a curved shape so as to be convex in a direction opposite to the ejection direction.

  As shown in FIGS. 4 and 7, the outer side surface 163b has a shape that inclines so as to gradually move inward (in a direction opposite to the ejection direction) toward the adherend surface S in the contact state. ing. A rear end portion of the outer side surface 163b in the pushing direction is smoothly connected to a tip end portion of the outer peripheral surface of the connecting portion 162 in the pushing direction.

  As shown in FIG. 8, the facing surface 163c has a shape such that the circumferential dimension of the gap C increases in the discharge direction. In the present embodiment, the facing surface 163c is set to have a shape in which the dimension of the gap C in the circumferential direction is larger than the tangent line L that passes through the axis O and is in contact with the inner side surface 163a in the discharge direction.

  A portion of the tip of the connecting portion 162 in the extruding direction, which is located between the gap forming portions 163, constitutes a defining surface 165 that faces the adhered surface S in the contact state. The defining surface 165 defines the gap C at a position where the defining surface 165 faces the attached surface S with a gap C in the abutting state and contacts the container 400 passing through the gap C. Both ends of the defining surface 165 in the circumferential direction are connected to the facing surface 163c. The defining surface 165 has a shape that inclines so as to gradually approach the adherend surface S in the abutting state toward the ejection direction. As shown in FIG. 9, the defining surface 165 has a shape that gradually inclines toward the opposite direction to the extruding direction as it is separated from the facing surface 163c of the gap forming portion 163 in the circumferential direction.

  As shown in FIG. 4, the plug member 180 has a shape capable of sealing the opening on the one end side of the housing portion 110 in the central axis direction of the housing portion 110. In the present embodiment, the plug member 180 is arranged inside the housing portion 110. The plug member 180 has a shape that allows the outer peripheral surface of the plug member 180 to be in close contact with the inner peripheral surface of the accommodating portion 110 while being relatively displaceable with respect to the accommodating portion 110 along the extrusion direction. The plug member 180 is pressed by the pushing member 200 in the pushing direction to push the containing body 400 along the pushing direction while being relatively displaced with respect to the housing portion 110. That is, the plug member 180 also functions as the “container pressing member 180” that presses the container 400 in the pushing direction. Specifically, the plug member 180 has a contact portion 181, a fitting portion 182, and a container pressing portion 183.

  The close contact portion 181 is formed in a cylindrical shape and has an outer peripheral surface that can be in close contact with the inner peripheral surface of the housing portion 110.

  The fitting portion 182 has a shape capable of fitting with the tip portion 211 of the pushing member 200. The fitting portion 182 is formed in a cylindrical shape having an outer diameter smaller than the inner diameter of the contact portion 181. The fitting portion 182 is connected to the contact portion 181 at a position where the central axis of the fitting portion 182 and the central axis of the contact portion 181 coincide with each other.

  The container pressing portion 183 is connected to the distal end portions of the contact portion 181 and the fitting portion 182 in the pushing direction, and has a shape that closes the opening of the contact portion 181 in the pushing direction over the entire area.

  The push-out member 200 has a rotation operation (an operation of rotating the push-out member 200 around the central axis of the push-out member 200 with respect to the housing member 100) and a pushing operation (moving the push-out member 200 with respect to the housing member 100 along the pushing direction). This is a member for pushing out the container 400 from the containing member 100 in a plurality of times by alternately repeating (pushing operation). In the present embodiment, the rotation direction of the rotation operation is set clockwise in plan view. As shown in FIG. 1, FIG. 4, FIG. 10, etc., the pushing member 200 has a grip portion 210, a pushing shaft portion 220, a plurality of pushing position defining portions 230, and a blocking portion 240.

  The grip 210 is a part for the operator to grip. The grip portion 210 is formed in a cylindrical shape whose outer diameter gradually decreases in the pushing direction. This shape improves the ease of gripping the grip 210 by the operator.

  The push-out shaft portion 220 has a shape extending along the push-out direction from the tip end portion of the grip portion 210 in the push-out direction. The pushing shaft portion 220 is formed in a tubular shape, and has a shape capable of pushing out the housing body 400 in the housing portion 110. In the present embodiment, the extrusion shaft portion 220 is formed in a cylindrical shape. The outer diameter of the extrusion shaft portion 220 is set smaller than the inner diameter of the housing portion 110. As shown in FIGS. 3 and 11, the extrusion shaft portion 220 is formed with a plurality of openings 222. In this embodiment, eight openings 222 are formed in the extrusion shaft portion 220. Each opening 222 has a shape that penetrates the extrusion shaft portion 220 in the radial direction (thickness direction) of the extrusion shaft portion 220. The plurality of openings 222 are provided at positions separated from each other in the central axis direction of the extrusion shaft portion 220 and separated from each other in the circumferential direction of the extrusion shaft portion 220. Specifically, the four openings 222 out of the eight openings 222 are spaced from each other in the central axis direction of the extrusion shaft portion 220 and are provided at the same position in the circumferential direction of the extrusion shaft portion 220. The remaining four openings 222 out of the eight openings 222 are provided at positions separated from the four openings 222 by 180 degrees in the circumferential direction of the extrusion shaft portion 220 and apart from each other in the central axis direction of the extrusion shaft portion 220. There is.

  As shown in FIG. 4, the tip end portion 221 of the extrusion shaft portion 220 is formed in a shape that can be fitted into the fitting portion 182 of the plug member 180. In this embodiment, the tip portion 221 of the extrusion shaft portion 220 is formed in a cylindrical shape.

Accordingly, it has a shape in which the amount of protrusion from the outer peripheral surface of the extrusion shaft portion 220 gradually increases.

  The leg portion 270 is a portion for specifying the angular relationship between the pushing shaft portion 220 and the regulating portion 120 when the pushing member 200 is mounted on the housing member 100. The leg portion 270 is formed in a portion of the extrusion shaft portion 220 that is separated from the second raised portion 262 in the extrusion direction. Specifically, the leg portion 270 is formed in a cantilever shape extending from the portion along the extrusion direction.

Have. As shown in FIG. 14, the leg portion 270 has a shape that can pass through the avoidance portion 141 along the extrusion direction.

  Next, a method of using the present extrusion tool will be described. When the present extrusion tool is used, first, the extrusion member 200 is attached to the housing member 100. Then, by repeating the rotating operation and the pushing operation alternately, the containing body 400 is pushed out from the containing member 100 in a plurality of times. Specifically, the pushing of the container 400 is achieved by one rotation operation and one push operation. When a plurality of push-outs are completed (when all the containing bodies 400 in the containing member 100 are pushed out), the pushing member 200 is pulled out from the containing member 100, and the containing member 100 is discarded. Hereinafter, description will be made in order from the mounting of the pushing member 200 to the housing member 100.

(1) Mounting of Extruding Member 200 on Housing Member 100 First, the pushing member 200 is mounted on the housing member 100. Specifically, in the state where the angle relationship between the extrusion shaft portion 220 and the restriction portion 120 is the angle relationship (angle relationship in FIGS. 12 to 14) in which the leg portion 270 is located inside the avoidance portion 141, the extrusion shaft portion 220 is It inserts in the accommodation member 100 along an extrusion direction. At this time, as shown in FIG. 14, after the start of insertion of the tip end portion 221 of the extrusion shaft portion 220 into the regulation portion 120, the four pressure contact portions 250 that are separated from each other at 90 degree intervals in the circumferential direction are the regulation portion 120. The inner peripheral surface 127a is continuously pressed at the same time. Therefore, the displacement (rattle) of the pushing member 200 in the direction orthogonal to the axis with respect to the housing member 100 and the inclination of the central axis of the pushing shaft portion 220 with respect to the central axis of the housing portion 110 are suppressed. Therefore, the insertion posture of the pushing member 200 with respect to the housing member 100 at the time of mounting, which tends to be particularly unstable, is stable.

  In addition, in the present embodiment, since the inner peripheral surface of the housing portion 110 has a shape that is separated from each pressure contact portion 250 in the axis orthogonal direction while the extrusion shaft portion 220 is displaced along the extrusion direction, a plurality of pressure contact portions is formed. 250 is simultaneously pressed against the inner peripheral surface 127a of the regulating portion 120 while passing through the regulating portion 120 during the mounting, and at the time of a pushing operation after passing through the regulating portion 120, the inner periphery of the housing portion 110 is Do not press the surfaces at the same time. Therefore, the insertion posture of the pushing member 200 with respect to the housing member 100 at the time of mounting is stable, and the pushing member 200 is inserted into the housing portion 110 at the time of a pushing operation after each pressure contact portion 250 passes through the restriction portion 120. The increase in resistance is suppressed.

  Then, the most distal bulging portion 232f comes into contact with the lower stage receiving portion 123 to restrict further pushing operation of the pushing member 200, whereby the mounting is completed. At this time, the bulging portion 232 positioned one rearward of the most distal bulging portion 232f in the pushing direction (the bulging portion 232 located closest to the tip end in the pushing direction in the second bulging portion group) is It does not come into contact with the upper receiving portion 124. In the present embodiment, the respective pressure contact portions 250 continue to be in pressure contact with the inner peripheral surface 127a of the restriction portion 120 at the same time until the most distal bulging portion 232f contacts the lower stage receiving portion 123. Further, the tip end portion of the first raised portion 261 also comes into pressure contact with the inner peripheral surface 127 a of the lower stage side surrounding portion 128.

  Here, when the mounting is completed (see FIG. 15 ), the most distal bulging portion 232f, that is, both the protrusion 233 and the overhanging portion 234 contact the lower stage receiving portion 123, and thus contact the lower stage receiving portion 123. The area of the part is sufficiently secured. Therefore, it is possible to effectively prevent the pushing member 200 from being erroneously pushed in after the mounting is completed, and reduce the reaction force that the projection 233 receives from the lower stage receiving portion 123 when the mounting is completed, so that the projection 233 is damaged. Is also suppressed. Although FIG. 15 does not show the time when the mounting is completed, the positional relationship between the bulging portion 232 and the receiving portion 122 is the same as that when the mounting is completed.

  Further, when the mounting is completed, the tip end portion 221 of the push-out shaft portion 220 fits into the fitting portion 182 of the plug member 180.

  Then, the cap 500 is removed. The cap 500 may be removed before the mounting.

(2) Pushing out of the container 400 (2-1) First rotation operation to the push-in position After the mounting, the most distal bulging portion 232f is in contact with the lower receiving portion 123. From this state, the pushing member 200 is rotated (the pushing member 200 is displaced relative to the housing member 100 in the circumferential direction). In the present embodiment, the pushing member 200 is rotated in the forward rotation direction (clockwise in plan view), that is, in the direction in which the most distal bulging portion 232f approaches the avoidance portion 141. During this rotation operation, the raised portion 260 continues to be in pressure contact with the inner peripheral surface 127a of the restriction portion 120. Specifically, during the rotating operation, the first raised portion 261 continues to be in pressure contact with the inner peripheral surface 127a of the lower stage surrounding portion 128, and the second raised portion 262 is in pressure contact with the inner peripheral surface 127a of the upper stage side surrounding portion 129. Keep doing. Then, when a portion of the overhanging portion 234 on the front end side in the forward rotation direction comes into contact with the boundary between the first step portion 125 and the upper step side enclosing portion 129, the boundary is stretched during the subsequent rotating operation of the pushing member 200. The protrusion 234 is continuously pressed inward in the radial direction. That is, in the present embodiment, the boundary between the first step portion 125 and the upper step side surrounding portion 129 presses the bulging portion 232 inward in the radial direction “bulging portion pressing portion 142 (bulging portion pressing portion 142)”. To make up. The dimension of the bulging portion pressing portion 142 in the pushing direction is set to be equal to or less than the dimension in the central axis direction between the protrusions 233. In the present embodiment, after the contact of the overhanging portion 234 with the bulging portion pressing portion 142, the bending of the bending piece 231 (the amount of displacement of the protrusion 233 inward in the radial direction) is accompanied by the rotation operation of the pushing member 200. It gets bigger and bigger.

  Then, the protrusion 233 (primary insertion protrusion 233a) of the most distal bulging portion 232f abuts on the first step portion 125, and further rotation operation of the extrusion member 200 in the forward rotation direction is restricted, and thereby the rotation is performed. The operation is completed. At this time, as shown in FIGS. 16 to 18, the primary insertion protrusion 233a fits inside the avoidance portion 141. Therefore, the pushing operation of the pushing member 200 in the pushing direction becomes possible. As described above, in the present extrusion device, the push-in position defining portion 230 capable of defining one push-in operation is connected to the push-out shaft portion 220 for pushing out the container 400, and the regulating portion 120 is the push-in position defining portion. Since the bulging portion pressing portion 142 having a shape capable of pressing 230 toward the inner side in the direction orthogonal to the axis is included, it is possible to push out the container 400 in a plurality of times while simplifying the structure of the pushing member 200. Is possible.

  In the present embodiment, when the rotation operation is completed, the raised portions 261 and 262 fit into the recesses 143 and 144, so that the operator is given a so-called click feeling. Specifically, the push-out member 200 is rotationally operated from the state where the primary insertion protrusion 233a is in contact with the lower stage receiving portion 123 (the state where the mounting is completed) until the primary insertion protrusion 233a fits inside the avoidance portion 141. During this time, since the respective raised portions 261 and 262 continue to be pressed against the inner peripheral surface 127a of the restriction portion 120, the operator feels resistance to the rotation operation during this time, while the primary insertion protrusion 233a is set inside the avoidance portion 141. Since the raised portions 261 and 262 fit into the recesses 143 and 144 (when the pushing operation becomes possible), the resistance is reduced. The change (reduction) in resistance during the rotating operation is transmitted to the operator as a click feeling. Therefore, the operator can clearly recognize that the pushing operation of the pushing member 200 is possible.

  In addition, in the present embodiment, each of the raised portions 261 and 262 has a shape in which the amount of protrusion from the outer peripheral surface of the extrusion shaft portion 220 gradually increases in the direction opposite to the forward rotation direction. The resistance when rotating the pushing member 200 in the direction opposite to the forward rotation direction is more than the resistance when rotating the pushing member 200 in the forward rotation direction from the state in which 262 is fitted in the recesses 143 and 144. Will grow. Therefore, it is possible to prevent the pushing member 200 from being rotated in the opposite direction from the state in which the raised portions 261 and 262 are fitted into the recessed portions 143 and 144.

  Further, in the present embodiment, the protrusion amount of the protrusion 233 from the outer peripheral surface of the extrusion shaft portion 220 is set to be larger than that of the overhang portion 234, so that the bending of the bending piece 231, that is, the bending piece 231 The pushing position can be effectively defined while suppressing an increase in bending stress generated at the boundary with the extrusion shaft portion 220. Specifically, the protrusion 233 having a relatively large protrusion amount is connected to the tip end portion (end portion on the free end side) of the bending piece 231, that is, the portion of the bending piece 231 having the largest bending, and A protruding portion 234 having a relatively small protrusion amount is provided at a portion between the base end portion (end portion on the fixed end side) and the distal end portion, that is, a portion of the bending piece 231 having a smaller bending than the distal end. Since they are connected, the extrusion shaft portion is suppressed while suppressing an increase in the bending of the bending piece 231 necessary to displace the entire bulging portion 232 inward of the inner edge portion 121 of the regulating portion 120 in the axis orthogonal direction. By effectively ensuring the contact area between the bulging portion 232 and the receiving portion 122 when the 220 is displaced in the pushing direction, the pushing position can be effectively defined.

  In the present embodiment, when the rotation operation is completed, the secondary insertion protrusion 233b overlaps the lower receiving portion 123 in the pushing direction, and the tertiary insertion protrusion 233c overlaps the upper receiving portion 124 in the pushing direction.

  Then, the contact portion 164 of the ejection portion 160 is brought into contact with the adherend surface S. At this time, all the contact portions 164 simultaneously contact the adhered surface S, so that the posture of the extrusion device when the contact portions 164 are contacted with the adhered surface S is stable. More specifically, since the contact surface, which is the tip of each gap forming portion 163, is formed into a flat surface capable of making surface contact with the adhered surface S, the contact surface and the adhered surface S are The contact area of is secured. Therefore, the posture of the pushing tool when the contact surfaces are brought into contact with the adherend surface S is stable. In this state, a discharge region capable of discharging the container 400 (adhesive body 400) is formed outside the contact portion 164 of the adherend surface S. The contact of the contact portion 164 with the adherend surface S may be performed before the rotation operation or during the rotation operation.

(2-2) First Pushing Operation At the end of the rotating operation, the primary insertion protrusion 233a is contained in the avoiding portion 141. In this state, the pushing operation of the pushing member 200 (the pushing operation of the pushing member 200 along the pushing direction) is performed. Then, the pushing shaft portion 220 presses the plug member 180 along the pushing direction, and thereby the container 400 is discharged from the discharging portion 160 to the discharging region. Specifically, the housing body 400 in the housing portion 110 flows out from the outlet in the partition portion 161 along the extrusion direction, and then contacts the area inside the contact portion 164 of the adhered surface S. If the pushing member 200 is continuously pushed in after that, the container 400 moves in the circumferential direction toward the ejection area formed outside the contact portion 164 of the adherend surface S, as shown in FIG. It is radially discharged only from the plurality of gaps C arranged intermittently. In detail, in the area where each gap forming portion 163 exists, the adhesive body 400 is blocked from flowing on the attached surface S toward the outside of the contact portion 164, while the gap C is formed. In the region, it is allowed to flow outward along the adhered surface S through the gap C. More specifically, in the area where each gap forming portion 163 is present, the adhesive body 400 faces the both gaps C formed on both sides in the circumferential direction of the gap forming portion 163 by the inner side surface 163a of the gap forming portion 163. In the area in which the gap C is formed by being guided by the inside of the contact portion 164, the area flowing toward the clearance C from the area inside the contact portion 164 and the area guided by the inner side surfaces 163a on both sides of the clearance C into the clearance C. While merging with each other, they flow so as to spread outward along the adhered surface S through the gap C. Note that FIG. 21 shows only the container 400 discharged from the single gap C for the sake of explanation.

  As the pushing operation of the pushing member 200 is continued, the adhesive body 400 that has flowed out to the outside of the contact portion 164 through each of the gaps C becomes the adherend surface S on the discharge area as shown in FIG. It has a shape that rises from the adherend S while flowing further outward along the surface. Note that, also in FIG. 22, only the container 400 discharged from the single gap C is shown.

  While this pushing operation is performed, the plug member 180 is relatively displaced with respect to the housing portion 110 along the extrusion direction while the outer peripheral surface of the contact portion 181 is brought into close contact with the inner peripheral surface of the housing portion 110. Therefore, by pushing the stopper member 180 with the pushing member 200 along the pushing direction without removing the stopper member 180 from the housing portion 110, the container 400 can be pushed out while maintaining the sealed state in the housing portion 110. ..

  Further, while the pushing operation is being performed, the pushing shaft portion 220 is supported by the housing member 100 at two positions of the pushing shaft portion 220 which are separated from each other in the pushing direction, so that the pushing member 200 during the pushing operation is pressed. The posture is stable. Specifically, the tip end portion 221 of the extrusion shaft portion 220 is in close contact with the housing portion 110 via the fitting portion 182 and the contact portion 181 of the plug member 180, and a part of the other portion of the extrusion shaft portion 220 is Since the restricting portion 120 is in contact with the inner peripheral surface 127a, displacement of the pushing member 200 in the radial direction (axis orthogonal direction) with respect to the housing member 100 and inclination of the central axis of the pushing shaft portion 220 with respect to the central axis of the housing portion 110 are suppressed. To be done.

  Further, during this pushing operation, the state in which the raised portions 261 and 262 are fitted into the recessed portions 143 and 144 is maintained, so that the pushing posture of the pushing member is further stabilized.

  Then, the protrusion 233 of the most distal bulge portion 232f passes through the avoidance portion 141, and the bulge portion including the primary insertion protrusion 233a (the protrusion 233 located closest to the tip end side in the extrusion direction of the second bulge portion group). The bulging portion 232 is in contact with the lower stage receiving portion 123 and includes the secondary insertion protrusion 233b (the protrusion 233 located one rear in the pushing direction from the most distal bulging portion 232f in the first bulging portion group). Is pressed against the upper-stage receiving portion 124, further pushing operation of the pushing member 200 is restricted, whereby the pushing operation is completed. At this time, the bulging portion 232 including the primary insertion protrusion 233a is received by the lower stage receiving portion 123, and the bulging portion 232 including the secondary insertion protrusion 233b is received by the upper stage receiving portion 124. As compared with the case where only the most distal bulging portion 232f is received by the lower receiving portion 123, the reaction force that the bulging portion 232 receives from the receiving portion 122 when each bulging portion 232 contacts the receiving portion 122 is reduced. It Therefore, damage to each bulged portion 232 (protrusion 233) is suppressed.

  Further, at the end of the pushing operation, as shown in FIGS. 4 and 19, the bending piece 231 elastically returns to the steady state in which no external force acts on the bending piece 231. Specifically, in the present embodiment, the dimension of the bulging portion pressing portion 142 in the pushing direction is set to be equal to or less than the dimension in the central axis direction between the protrusions 233, and moreover, the second inclined portion 132 and the arc portion 133. Has a shape that is radially separated from the projection 233, so that after the pushing operation is finished, the pressing of the most distal bulging portion 232f by the bulging portion pressing portion 142 is released, and the bending piece 231 elastically returns to the steady state. .. Therefore, the creep deformation of the bending piece 231 after the pushing operation is completed is suppressed.

  Further, in the present embodiment, since the arrangement of the bulging portions 232 is set such that the stroke of the first pushing operation is longer than the stroke of the pushing operation of the second time and thereafter, the bulging portions 232 are accommodated by the first pushing operation. The amount of the container 400 pushed out of the member 100 becomes larger than the amount of the container 400 pushed out of the container member 100 by the second and subsequent pushing operations. Therefore, it is possible to prevent the amount of extrusion by the first pushing operation from being smaller than the amount of extrusion by the second and subsequent pushing operations due to a slight variation in the filling amount of the housing body 400 in the housing portion 110. Therefore, the pushing amount of the container 400 at each pushing operation is ensured to be a predetermined amount or more.

  Then, when the pushing operation is completed, a shape (for example, petals) extending in a direction parallel to the ejection direction is formed at a plurality of locations (six locations in the present embodiment) in the ejection area outside the contact portion 164 of the adherend surface S. Adhesive body 400 adheres to the shape.

  Here, in the state shown in FIGS. 21 and 22, the container 400 discharged outward from the two adjacent gaps C along the attached surface S has a gap formation located between the gaps C. By flowing so as to wrap around the outside of the portion 163, it contacts the outside surface 163b of the gap forming portion 163. From this state, when the discharge section 160 is displaced from the adherend surface S by displacing the discharge section 160 in the direction opposite to the extrusion direction (upward in FIG. 22), as shown in FIG. The adherent 450 is formed on the adhering surface S. In this embodiment, the adhering body 450 is formed in a shape simulating a flower. At this time, when the present extrusion tool is stored, it is erected on the mounting table 300 as shown in FIG.

  As described above, in the present extruding device, the ejection area is formed outside the abutting portion 164 of the adherend surface S, so that the size of the accommodating body in the orthogonal direction to the extruding direction does not need to be increased. A discharge area capable of discharging 400 is ensured in a discharge region outside the contact portion 164, and further, the container 400 is provided with a gap C toward the discharge region, that is, along the discharge direction. Since the fluid flows so as to spread upward, by adjusting the pushing amount of the pushing member 200 (the discharge amount of the container 400), the container 400 is changed into various shapes in the discharge region outside the contact portion 164. It becomes possible. In other words, the ejection area is formed outside the contact portion 164 of the adhered surface S, and is housed outward along the adhered surface S so as to be directed to the ejection area via the gap C. By ejecting the body 400, it is possible to avoid both the increase in size in the direction orthogonal to the axis and the flexible change of the outer shape of the attachment body 450.

  In addition, in the present extrusion device, the container 400 that flows so as to spread outward on the adherend surface S through the gap C contacts the defining surface 165. In the present embodiment, the defining surface 165 has a shape that inclines so as to approach the adherend surface S toward the outside in the abutting state, so that the container 400 that spreads outward through the gap C is The regulation surface 165 receives the guidance such that the surface 165 is pressed toward the adherend surface S. Therefore, the frictional resistance received from the adhered surface S by the container 400 flowing so as to spread on the adhered surface S along the ejection direction is increased. Therefore, the adhesiveness of the container 400 to the adherend surface S is improved. Further, the container 400, which flows so as to spread outward on the adhered surface S through the gap C, contacts the defining surface 165 and simultaneously contacts the facing surface 163c. In the present embodiment, the facing surface 163c is set to have a shape in which the gap C gradually increases from the inner side to the outer side in the direction parallel to the ejection direction. Along with this, the volume of the container 400 discharged to the outside of the contact portion 164 increases. Therefore, the contact area between the container 400 and the surface S to be attached is increased, so that the adhesion of the container 400 to the surface S to be attached is further improved.

  Further, when the discharge section 160 is separated from the adhered surface S, shear resistance acts on the container 400 along the outer side surface 163b of the gap forming section 163. More specifically, the shear resistance acts along a surface that includes each outer surface 163b and that is continuous over the entire area in the circumferential direction. Therefore, in the attached body 450, in addition to the portion in contact with the outer side surface 163b of the gap forming portion 163, the attached surface S is also attached to the portion located between the outer side surfaces 163b adjacent to each other in the circumferential direction. The inner side surface is formed so as to gradually face inward as it goes. Therefore, for example, even when the adhering material 450 is formed on the inner surface of the toilet bowl and the water flow collides with the adhering material 450, the water flow collides with the inner surface of the adhering material 450 so that the inner surface is separated from the water flow. Since the resistance to be received is suppressed, the detachment of the adhering body 450 existing on the downstream side from the inner side surface from the inner surface (adhered surface S) of the toilet bowl is suppressed.

  Further, in the present embodiment, since the gap forming portion 163 has the inner side surface 163a that is curved so as to be convex toward the inner side, the inner surface 163a of each gap forming portion 163 is contacted with the adherend surface S and then touched. The container 400 heading to the ejection region outside the contact portion 164 is smoothly guided by the inner side surface 163a of the gap forming portion 163 to the gap C on both sides in the circumferential direction of the inner side surface 163a.

(2-3) Rotation operation after pushing operation (rotation operation after the second time)
Here, only the contents different from the contents explained in the above (2-1) will be explained, and the contents similar to the above (2-1) will be omitted.

  From the end of the pushing operation (the same state as the relationship between the protrusion 233 and the regulating portion 120 shown in FIGS. 3 and 19), the pushing member 200 is rotated 180 degrees in the forward rotation direction.

  At the time of this rotation operation, the protrusion 233 that has passed through the avoidance portion 141 rotates inside the second inclined portion 132 and the arc portion 133 about the central axis of the extrusion shaft portion 220. In the present embodiment, the second inclined portion 132 and the arc portion 133 are radially retracted from the locus drawn by the protrusion 233 while the extrusion shaft portion 220 rotates about the central axis (while the extrusion member 200 is rotationally operated). Since the protrusion 233 has such a shape that the protrusion 233 comes into contact with the restriction portion 120 during this rotation operation (see FIG. 20 ). Therefore, since the bending deformation of the bending piece 231 is maintained while the pushing member is rotated 180 degrees in the forward rotation direction after completion of the pressing operation until the next pressing operation becomes possible. The creep deformation of is reliably suppressed.

(3) Withdrawal operation of the extruding member 200 In the present extruding device, when the container 400 in the accommodating portion 110 is completely extruded by alternately repeating the rotating operation and the pushing operation as described above, that is, eight extruding operations. Then, the adhesive cartridge 20 is used.

  Then, the pushing member 200 is pulled out of the housing member 100 in a direction opposite to the pushing direction. Here, since each protrusion 233 is connected to the bending piece 231, and the restricting portion 120 has a protrusion pressing portion (each inclined portion 131, 132), the pushing member 200 can be easily removed from the housing member 100. It is possible to pull it out. Specifically, when the push-out shaft portion 220 is pulled out from the accommodation portion 110 in the direction opposite to the push-out direction, the protrusion pressing portion pushes the protrusion 233 inward in the radial direction, whereby the bending piece 231 is bent and deformed, As a result, the protrusion 233 is displaced to the inside of the inner peripheral surface 127a (inner edge 121) of the surrounding portion 127. Therefore, regardless of the angular relationship between the restricting portion 120 and the pushing shaft portion 220, the pushing member 200 is pulled out by pulling the pushing member 200 in the direction opposite to the pushing direction.

  Further, each bending piece 231 has a shape extending from the extruding shaft portion 220 along the circumferential direction, and the dimension of each bending piece 231 in the circumferential direction is set to be larger than the dimension of the bending piece 231 in the central axis direction. Has been done. Therefore, it is necessary to arrange a plurality of protrusions 233 along the central axis direction of the extrusion shaft portion 220 while avoiding a significant increase in the size of the extrusion shaft portion 220 in the central axis direction, and for the pulling operation of the extrusion member 200. It is possible to reduce the required force. Specifically, since the circumferential dimension of each bending piece 231 is set to be larger than the dimension of the bending piece 231 in the central axis direction, when a plurality of protrusions 233 are arranged along the central axis direction. It is possible to avoid increasing the size of the extruding shaft portion 220 in the central axis direction. Further, since each bending piece 231 has a shape connected to the extruding shaft portion 220 at one end side in the circumferential direction, each bending piece 231 is As compared with the case of having a shape in which one end side in the central axis direction is connected to the extrusion shaft portion 220, to secure a large dimension in the direction (circumferential direction) connecting the extrusion shaft portion 220 and the protrusion 233 in each bending piece 231, that is, It is possible to reduce the force required to displace each protrusion 233 inward in the radial direction.

  Further, since each protrusion 233 has a shape in which the amount of protrusion from the outer peripheral surface of the extrusion shaft portion 220 gradually increases in the extrusion direction, it is possible to more easily pull out the extrusion member 200 from the housing member 100. . Specifically, during the pulling operation of pulling out the pushing member 200 from the housing member 100, as the pushing shaft portion 220 is displaced in the direction opposite to the pushing direction, the protrusion 233 is radially moved by the protrusion pressing portion (each inclined portion 131, 132). Is gradually pressed inward, that is, the bending (drawing resistance) of the bending piece 231 gradually increases, so that the pushing operation of the pushing member 200 from the housing member 100 is facilitated.

  Furthermore, since each protrusion 233 has a shape in which the amount of protrusion from the outer peripheral surface of the extrusion shaft portion 220 gradually decreases from the fixed end side of the bending piece 231 toward the free end side (in the direction opposite to the normal rotation direction). The contact area between the protrusion 233 and the protrusion pressing portion during the pull-out operation of the pushing member 200 is reduced. Therefore, the pushing member 200 can be more easily pulled out from the housing member 100.

  Further, in the present embodiment, the protrusion pressing portion has a shape that gradually inclines toward the inner side in the radial direction as it goes in the direction opposite to the pushing direction. Therefore, as the pushing shaft portion 220 is displaced in the direction opposite to the pushing direction, the protrusion 233 is gradually pressed inward in the radial direction by the protrusion pressing portion, that is, the bending of the bending piece 231 (pulling resistance). Is gradually increased, so that the operation of pulling out the pushing member 200 from the housing member 100 is further facilitated. Further, since the protrusion pressing portion has a shape that is continuously connected in the circumferential direction except for the avoiding portion 141, the pulling-out operation of the pushing member 200 can be easily performed regardless of the angular relationship between the regulating portion 120 and the pushing shaft portion 220. Become.

  In addition, in the present embodiment, since the blocking portion 240 is connected to the inner peripheral surface of the extrusion shaft portion 220, the bending piece 231 is prevented from being damaged during the pulling operation, and the longitudinal direction of the bending piece 231 (extrusion shaft) is suppressed. By increasing the dimension in the direction (connecting the portion 220 and the protrusion 233), the pullout resistance when pulling out the pushing member 200 from the housing member 100 can be reduced. Specifically, as shown in FIG. 18, the rear end portion of the protrusion 233 in the forward rotation direction contacts the blocking portion 240 so that the protrusion 233 is completely inward in the radial direction with respect to the outer peripheral surface of the extrusion shaft portion 220. Therefore, even when the size of the bending piece 231 in the longitudinal direction is increased, the bending of the bending piece 231, that is, the bending stress generated at the boundary between the bending piece 231 and the extrusion shaft portion 220 is prevented. Is suppressed. Therefore, the pullout resistance is reduced by increasing the size of the bending piece 231 in the longitudinal direction, and the breakage of the bending piece 231 is suppressed by suppressing the increase of the bending stress generated at the boundary between the bending piece 231 and the extrusion shaft portion 220. , Can be compatible.

  In addition, each bending piece 231 has a rear end portion and a rear end side facing portion 224 in the pushing direction of the bending piece 231 more than a gap h1 between the tip end portion in the pushing direction of the bending piece 231 and the leading end side facing portion 223. It has a shape that reduces the gap h2. Therefore, when the protrusion 233 comes into contact with the receiving portion 122 by the pushing operation of the pushing member 200, further pushing of the pushing member 200 is effectively suppressed, and the pushing member 200 is pulled out when the pushing member 200 is pulled out from the housing member 100. The resistance is effectively reduced. Specifically, the gap h2 between the rear end portion of the bending piece 231 in the pushing direction and the rear end side facing portion 224 is smaller than the gap h1 between the tip end portion of the bending piece 231 in the pushing direction and the leading end side facing portion 223. Therefore, as compared with the case where the sizes of both gaps are the same, a direction opposite to the pushing direction of the bending piece 231 when the projection 233 receives the reaction force from the receiving section 122 when the projection 233 contacts the receiving section 122. The amount of displacement in the pushing direction is small, and a large amount of displacement (bending) in the pushing direction of the bending piece 231 when the pushing member 200 is pulled out from the housing member 100 is secured.

  Then, after the push-out operation of the pushing member 200, the housing member 100 and the cap 500 are discarded. On the other hand, the pushing member 200 and the mounting table 300 can be reused when another adhesive cartridge 20 is used.

  It should be understood that the above-described embodiments disclosed this time are exemplifications in all respects and not restrictive. The scope of the present invention is shown not by the above description of the embodiments but by the scope of claims for patent, and includes meanings equivalent to the scope of claims for patent and all modifications within the scope.

  For example, the rotation operation may be omitted in the operation of pushing out the container 400 from the housing member 100. Specifically, the primary insertion protrusion 233a passes through the regulation portion 120 by further pushing the pushing member 200 in the pushing direction from the state where the primary insertion protrusion 233a is in contact with the regulation portion 120 without performing a rotating operation. You may. In this case, the inner edge portion 121 of the restriction portion 120 constitutes a “bulging portion pressing portion”. Specifically, the inner edge portion 121 (bulging portion pressing portion) is configured such that the extrusion shaft portion 220 is linear along the extrusion direction with respect to the regulation portion 120 from the state where the primary insertion protrusion 233a is in contact with the regulation portion 120. The bulging portion 232 is pressed toward the inner side in the direction orthogonal to the axis in accordance with the relative displacement in the shape.

  Further, the structure of the housing member 100 is not limited to the example of the above embodiment. For example, the regulation part 120 may be omitted, the upper end of the accommodation part 110 may constitute a “regulation part”, and the inner edge of the upper end of the accommodation part 110 may constitute a “bulging part pressing part”.
