That is, each of the inclined portions 131 and 132 has a shape capable of pressing the protrusion 233 radially inward of the push shaft portion 220 when the push shaft portion 220 is displaced in the direction opposite to the push direction. (first projecting portion pressing portion)”. In addition, the inner diameter of the surrounding portion 127 is set smaller than the outer diameter of the outer peripheral surface 181 of the plug member 180 .

The distance from the center of the surrounding portion 127 to the radially outer end of the second inclined portion 132 (the radius of the arc portion 133) is the distance from the central axis of the extrusion shaft portion 220 to the radially outer end of the protrusion 233. It is set larger than the distance. In the present embodiment, the second inclined portion 132 and the arc portion 133 are radially retracted from the trajectory drawn by the projection 233 while the extrusion shaft portion 220 rotates around the central axis (while the extrusion member 200 is rotated). It has a shape that

As shown in FIG. 14 , each pressure contact portion 250 is regulated during a period in which the tip portion 221 of the extrusion shaft portion 220 is inserted into the regulation portion 120 along the extrusion direction and the tip portion 221 is inserted by a predetermined stroke. It has a shape that continues to press against the inner peripheral surface 127a of the portion 120 at the same time. As shown in FIGS. 1, 12, and 13, of the four pressure contact portions 250, two adjacent pressure contact portions 250 have flexible pieces 231 connecting the distal end swelling portion 232f and the pushing shaft portion 220.

The raised portion 260 has a shape that protrudes (protrudes) radially outward from the outer peripheral surface of the extrusion shaft portion 220 . The raised portion 260 has a shape extending along the central axis direction of the extrusion shaft portion 220 . The raised portion 260 is provided on the outer peripheral surface of the extrusion shaft portion 220 at a portion between the first bulging portion group and the second bulging portion group. In this embodiment, the raised portion 260 has a first raised portion 261 and a second raised portion 262 .

As shown in FIG. 10 , the first raised portion 261 is formed on the outer peripheral surface of the push shaft portion 220 so that the rear end portion of the first raised portion group and the second raised portion group extend in the clockwise direction in plan view. is connected to the site between the tip of the The first raised portion 261 extends from the rear end portion (upper end portion in FIG. 10) of the extrusion shaft portion 220 in the extrusion direction to a portion closer to the tip portion 221 side of the extrusion shaft portion 220 than the most distal swelling portion 232f. It has a shape extending along the extrusion direction. Therefore, the tip portion of the first protruding portion 261 in the extrusion direction overlaps with each pressure contact portion 250 in the circumferential direction of the extrusion shaft portion 220 . That is, in the present embodiment, the tip portion of the first raised portion 261 also functions as a “pressure contact portion” when the pushing member 200 is attached to the accommodating member 100 .

As shown in FIG. 13 , the second raised portion 262 is formed on the outer peripheral surface of the push shaft portion 220 so as to extend between the distal end portion of the first raised portion group and the second raised portion group in the clockwise direction in plan view.

The second protrusion 262 extends from the rear end (the upper end in FIG. 10) of the extrusion shaft 220 in the extrusion direction to a position spaced apart in the circumferential direction from the distal end of the distalmost bulging portion 232f in the extrusion direction. It has a shape extending along the

In this embodiment, the lower enclosing part 128 and the upper enclosing part 129 are formed with recesses 143 and 144 that can be engaged with the protuberances 261 and 262, respectively. Each of the recesses 143 and 144 has a shape that is recessed outward in the radial direction from a portion of the inner peripheral surface 127a of the enclosing portion 127 other than the recesses 143 and 144 .

It has a shape that extends continuously along the central axis direction from one end to the other end of the upper enclosing part 129 in the central axis direction. When the primary insertion projection 233a and the restricting portion 120 are in the specific angular relationship (when the primary insertion projection 233a and the avoidance portion 141 are aligned in the radial direction), the recesses 143 and 144 are radially protuberant. It is formed at a position facing the portions 261 and 262 .

Each protruding portion 261, 262 presses outward in the radial direction against a portion of the inner peripheral surface 127a (inner edge portion 121) of the enclosing portion 127 other than the recessed portions 143, 144 and the avoiding portion 141, and It has a shape that fits into the recesses 143 and 144 when the insertion projection 233a and the avoidance portion 141 are arranged in the radial direction. In the present embodiment, each protuberance 261, 262 changes from the state in which the primary insertion projection 233a contacts the lower receiving portion 123 to the state in which the primary insertion projection 233a and the restricting portion 120 are in the specific angular relationship (1 The pushing member 200 rotates around the central axis of the pushing shaft portion 220 until the next insertion protrusion 233a and the avoiding portion 141 are aligned in the radial direction), and the direction is opposite to the forward rotation direction (clockwise direction in plan view).

The leg portion 270 is formed at a portion of the extrusion shaft portion 220 spaced apart 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. The leg portion 270 has a shape that allows the distal end portion (free end side) in the extrusion direction to be displaced radially inward with the rear end portion (fixed end side end portion) in the extrusion direction as a fulcrum. have As shown in FIG. 14, the leg portion 270 has a shape that allows it to pass through the avoidance portion 141 along the extrusion direction.

<3. How to use the extrusion tool>
Next, a method for using the pushing tool 700 will be described. When using the pushing tool 700 , first, the pushing member 200 is attached to the housing member 100 . By alternately repeating the rotating operation and the pushing operation, the contents 400 are pushed out from the containing member 100 in a plurality of times. Specifically, the extrusion of the content 400 is achieved by one rotation operation and one push operation. After a plurality of times of pushing out (when all the contents 400 in the containing member 100 have been pushed out), the pushing member 200 is pulled out from the containing member 100, and the containing member 100 is discarded. The mounting of the pushing member 200 to the housing member 100 will be described below.

<3-1. Mounting of Extruded Member to Accommodating Member>
First, the pushing member 200 is attached to the housing member 100 . Specifically, when the angular relationship between the pushing shaft portion 220 and the restricting portion 120 is such that the leg portion 270 is positioned within the avoiding portion 141 (the angular relations shown in FIGS. 12 to 14), the pushing shaft portion 220 is inserted into the housing member 100 along the extrusion direction. At this time, as shown in FIG. 14, after the start of insertion of the distal end portion 221 of the extrusion shaft portion 220 into the restricting portion 120, four pressure contact portions 250 spaced apart from each other at intervals of 90 degrees in the circumferential direction are formed in the restricting portion 120. continue to press against the inner peripheral surface 127a of the . Therefore, the displacement (rattling) of the pushing member 200 relative to the housing member 100 in the direction orthogonal to the axis 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 push-out member 200 with respect to the housing member 100, which tends to be unstable, is stabilized.

In addition, in the present embodiment, the inner peripheral surface of the accommodating portion 110 has a shape that separates from each pressure contact portion 250 in the direction perpendicular to the axis while the extrusion shaft portion 220 is displaced along the extrusion direction. 250 simultaneously presses against the inner peripheral surface 127a of the restricting portion 120 while passing through the restricting portion 120 at the time of attachment, and presses against the inner peripheral surface 127a of the accommodating portion 110 after passing through the restricting portion 120. Do not apply pressure to both surfaces at the same time. Therefore, the insertion posture of the push-out member 200 with respect to the housing member 100 is stabilized at the time of attachment, and the push-out member 200 can be inserted into the housing portion 110 during the pushing operation after each pressure contact portion 250 has passed through the restricting portion 120. An increase in resistance is suppressed.

Further, pushing operation of the push-out member 200 is regulated by the contact of the distal end bulging portion 232f with the lower stage receiving portion 123, thereby completing the attachment. In addition, at this time, the bulging portion 232 positioned one behind the most distal bulging portion 232f in the extrusion direction (the bulging portion 232 positioned most distally in the extrusion direction in the second bulging portion group) is It does not come into contact with the upper stage receiving portion 124 . In this embodiment, the pressure contact portions 250 continue to press against the inner peripheral surface 127a of the restricting portion 120 until the distal end bulging portion 232f contacts the lower receiving portion 123 at the same time. Also, the tip portion of the first raised portion 261 is also pressed against the inner peripheral surface 127 a of the lower enclosing portion 128 .

Here, when the attachment is completed (see FIG. 15), the distalmost bulging portion 232f, that is, both the projection 233 and the bulging portion 234 come into contact with the lower receiving portion 123. area is sufficiently secured. Therefore, it is effectively suppressed that the push-out member 200 is erroneously pushed in as it is after the mounting is completed, and the reaction force that the projection 233 receives from the lower stage receiving portion 123 when the mounting is completed is reduced, so that the projection 233 is damaged. is also suppressed. Although FIG. 15 does not show the completed attachment, the positional relationship between the bulging portion 232 and the receiving portion 122 is the same as that of the completed attachment.

Further, when the attachment is completed, the tip portion 221 of the pushing shaft portion 220 fits into the fitting portion 182 of the plug member 180 . Then, the cap 500 is removed. Note that the cap 500 may be removed before installation.

<3-2. Extrusion of contents>
<3-2-1. Rotational operation to the first push-in position>
After mounting, the distal end swelling portion 232f is in contact with the lower receiving portion 123. As shown in FIG. From this state, the pushing member 200 is rotated (the pushing member 200 is relatively displaced in the circumferential direction with respect to the housing member 100). 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 distalmost bulging portion 232f approaches the avoidance portion 141 . During this rotation operation, the raised portion 260 continues to press against the inner peripheral surface 127a of the restricting portion 120 . Specifically, during the rotation operation, the first raised portion 261 continues to press against the inner peripheral surface 127a of the lower enclosing portion 128, and the second raised portion 262 presses against the inner peripheral surface 127a of the upper enclosing portion 129. keep doing Then, when the portion of the projecting portion 234 on the tip side in the forward rotation direction abuts the boundary between the first stepped portion 125 and the upper stage side enclosing portion 129, the boundary projects when the pushing member 200 is subsequently rotated. Continue to push portion 234 radially inward. That is, in the present embodiment, the boundary between the first step portion 125 and the upper enclosing portion 129 presses the bulging portion 232 radially inward. ” constitutes. The dimension of the bulging portion pressing portion 142 in the direction of extrusion is set to be equal to or less than the dimension in the central axis direction between the projections 233 . In the present embodiment, after the projecting portion 234 abuts against the bulging portion pressing portion 142, the deflection of the flexible piece 231 (displacement amount of the protrusion 233 inward in the radial direction) is increased as the pushing member 200 is rotated. gradually grow larger.

Then, the projection 233 (primary insertion projection 233a) of the distalmost bulging portion 232f comes into contact with the first stepped portion 125, thereby restricting further rotation of the pushing member 200 in the forward rotation direction. Operation completes. At this time, as shown in FIGS. 16 to 18, the primary insertion projection 233a is accommodated within the avoidance portion 141. As shown in FIG. Therefore, it is possible to push the pushing member 200 in the pushing direction. As described above, in this push-out tool 700, the push-in position regulating portion 230 capable of regulating one pushing operation is connected to the push-in shaft portion 220 for pushing out the contents 400, and the regulating portion 120 regulates the push-in position. Since the expanded portion pressing portion 142 has a shape capable of pressing the portion 230 inward in the direction perpendicular to the axis, the structure of the pushing member 200 is simplified and the contents 400 are pushed out in multiple steps. becomes possible.

In this embodiment, when the rotation operation is completed, the raised portions 261 and 262 fit into the recessed portions 143 and 144, so that the operator is given a so-called click feeling. Specifically, the pushing member 200 is rotated from the state in which the primary insertion protrusion 233a is in contact with the lower receiving portion 123 (the state in which the attachment is completed) until the primary insertion protrusion 233a is accommodated in the avoiding portion 141. During this time, the protuberances 261 and 262 continue to press against the inner peripheral surface 127a of the restricting portion 120, so the operator feels resistance to the rotating operation during this time. (When the pushing operation becomes possible), the raised portions 261 and 262 fit into the recessed portions 143 and 144, so the resistance is reduced. The change (decrease) in resistance during this rotation 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 enabled.

Further, 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 forward rotation direction and the opposite direction. 262 is fitted in each of the recesses 143 and 144, the resistance when rotating the ejecting member 200 in the forward rotating direction is greater than the resistance when rotating the ejecting member 200 in the forward rotating direction and the reverse direction. becomes larger. Therefore, the pushing member 200 is prevented from being rotated in the opposite direction from the state in which the projections 261 and 262 are fitted into the recesses 143 and 144 .

Further, in the present embodiment, the protrusion 233 projects from the outer peripheral surface of the pushing shaft portion 220 by a larger amount than that of the projecting portion 234. It is possible to effectively define the push-in position while suppressing an increase in bending stress generated at the boundary with the push-out shaft portion 220 . Specifically, a protrusion 233 having a relatively large amount of protrusion is connected to the distal end (the end on the free end side) of the flexible piece 231 , that is, the portion of the flexible piece 231 that bends the most. A protruding portion 234 having a relatively small amount of protrusion is formed at a portion between the base end portion (the end portion on the fixed end side) and the tip portion, that is, a portion of the flexible piece 231 that bends less than the tip portion. Therefore, while suppressing an increase in the bending of the bending piece 231 necessary for displacing the entire bulging portion 232 inward of the inner edge portion 121 of the restricting portion 120 in the direction perpendicular to the axis, the pushing shaft portion By effectively securing 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 this 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 discharge portion 160 is brought into contact with the surface S to be adhered. At this time, since all the contact portions 164 are in contact with the adherend surface S at the same time, the posture of the pushing tool 700 when these contact portions 164 are in contact with the adherend surface S is stabilized. More specifically, the abutment surface, which is the tip of each gap forming portion 163, is formed in a flat surface that can come into surface contact with the adherend surface S, so that each abutment surface and the adherend surface S contact area is ensured. Therefore, the posture of the pushing tool 700 when these contact surfaces are brought into contact with the adhered surface S is stabilized. In this state, an ejection region is formed outside the contact portion 164 of the attachment surface S, where the content 400 (viscous body 400) can be ejected. The abutment of the abutting portion 164 to the adhered surface S may be performed before or during the rotating operation.

<3-2-2. First pushing operation>
The primary insertion projection 233a is housed within the avoidance portion 141 at the end of the rotating operation. In this state, the pushing operation of the pushing member 200 (the pushing operation of pushing the pushing member 200 along the pushing direction) is performed. As a result, the plug member 180 is pushed along the extrusion direction by the push shaft portion 220 , thereby discharging the contents 400 from the discharge portion 160 into the discharge area. Specifically, the contents 400 in the accommodating portion 110 come into contact with a region of the attachment surface S inside the contact portion 164 after flowing out from the outlet in the partition portion 161 along the extrusion direction. When the pushing member 200 is continued to be pushed in after that, the content 400 is pushed in the circumferential direction toward the ejection area formed outside the contact portion 164 on the attachment surface S, as shown in FIG. The liquid is discharged radially only from the intermittently arranged gaps C. Specifically, in the area where each gap forming part 163 exists, the adhesive body 400 is blocked from flowing on the adherend surface S toward the outside of the contact part 164, while the gap C is formed. In the region, the liquid is allowed to flow outward along the adhered surface S through the gap C. As shown in FIG. More specifically, in the region where each gap forming portion 163 exists, the viscous body 400 is directed toward both gaps C formed on both sides of the gap forming portion 163 in the circumferential direction by the inner side surfaces 163a of the gap forming portion 163. In the area where the gap C is formed, the part that flows from the area inside the contact part 164 toward the gap C and the part that is guided to the gap C by the inner side surfaces 163a on both sides of the gap C flows along the surface S to be adhered through the gap C so as to spread outward. In addition, in FIG. 21, only the content 400 ejected from the single gap C is shown for explanation.

As the pushing operation of the pushing member 200 is continued, the viscid substance 400 flowing out of the contact portion 164 through the gaps C spreads over the ejection region onto the adherend surface S as shown in FIG. It becomes the shape which protrudes from the to-be-adhered surface S, flowing further outward along. Note that FIG. 22 also shows only the content 400 ejected from a single gap C. As shown in FIG.

While this pushing operation is being performed, the plug member 180 is relatively displaced with respect to the accommodating portion 110 along the pushing direction while keeping the outer peripheral surface of the outer peripheral surface 181 in close contact with the inner peripheral surface of the accommodating portion 110 . Therefore, by pushing the plug member 180 along the extrusion direction with the pushing member 200 without removing the plug member 180 from the storage section 110, the contents 400 can be pushed out while maintaining the sealed state inside the storage section 110. .

In addition, while the pushing operation is being performed, the pushing shaft portion 220 is supported by the housing member 100 at two locations separated from each other in the pushing direction. Posture stabilizes. Specifically, the distal end portion 221 of the push shaft portion 220 is in close contact with the housing portion 110 via the fitting portion 182 and the outer peripheral surface 181 of the plug member 180, and part of the other portion of the push shaft portion 220 is Since it is in contact with the inner peripheral surface 127a of the restricting portion 120, the displacement of the pushing member 200 in the radial direction (direction orthogonal to the axis) with respect to the accommodating member 100 and the inclination of the central axis of the pushing shaft portion 220 with respect to the central axis of the accommodating portion 110 are suppressed. be done.

Furthermore, during this pushing operation, the protrusions 261 and 262 are kept fitted in the recesses 143 and 144, so that the pushing posture of the pushing member is further stabilized.

Then, the projection 233 of the distalmost swelling portion 232f passes through the avoiding portion 141, and the swelling portion including the primary insertion projection 233a (the projection 233 located on the distal end side of the second swelling portion group in the extrusion direction). 232 abuts on the lower receiving portion 123 and includes a secondary insertion projection 233b (a projection 233 positioned one rearward in the extrusion direction from the most distal swelling portion 232f in the first swelling portion group). abuts against the upper receiving portion 124, the push-in operation of the push-out member 200 is regulated, thereby completing the push-in operation. At this time, the swelling portion 232 including the primary insertion protrusion 233a is received by the lower receiving portion 123 and the swelling portion 232 including the secondary insertion protrusion 233b is received by the upper receiving portion 124. Compared to the case where only the leading end swelling portion 232f is received by the lower stage receiving portion 123, the reaction force that the swelling portion 232 receives from the receiving portion 122 when each swelling portion 232 comes into contact with the receiving portion 122 is reduced. be. Therefore, breakage of each bulging portion 232 (projection 233) is suppressed.

4 and 19, the flexible piece 231 elastically returns to a normal state where no external force acts on the flexible piece 231 when the pushing operation is completed. Specifically, in the present embodiment, the dimension of the bulging portion pressing portion 142 in the extrusion direction is set to be equal to or less than the dimension in the central axis direction between the projections 233, and the second inclined portion 132 and the arc portion 133 has a shape radially spaced apart from the projection 233, after the pushing operation is completed, the pressure of the distalmost bulging portion 232f by the bulging portion pressing portion 142 is released, and the flexible piece 231 elastically returns to its normal state. . Therefore, creep deformation of the flexible piece 231 after the pushing operation is completed is suppressed.

In addition, in the present embodiment, since the arrangement of each bulging portion 232 is set so that the stroke of the first pressing operation is longer than the stroke of the second and subsequent pressing operations, the first pressing operation accommodates the bulging portion 232 . The amount of contents 400 pushed out from member 100 becomes larger than the amount of contents 400 pushed out from accommodating member 100 by the second and subsequent pushing operations. Therefore, it is possible to prevent the amount of pushing out by the first pushing operation from becoming smaller than the amount of pushing out by the pushing operation for the second and subsequent times due to slight variations in the filling amount of the contents 400 in the storage portion 110 . Therefore, it is ensured that the content 400 is pushed out by a predetermined amount or more during each push-in operation.

By the end of the pressing operation, a shape extending in a direction parallel to the ejection direction (e.g., a petal shape) is formed at a plurality of locations (six locations in this embodiment) in the ejection region outside the contact portion 164 of the attachment surface S. The sticky substance 400 adheres to the shape).

Here, in the state shown in FIGS. 21 and 22, the content 400 ejected outward along the adhering surface S from two gaps C adjacent to each other forms a gap positioned between both gaps C. It contacts the outer surface 163 b of the gap forming portion 163 by flowing around the outside of the portion 163 . From this state, when the ejection part 160 is displaced in a direction opposite to the extrusion direction (upward in FIG. 22) to separate the ejection part 160 from the adhered surface S, as shown in FIG. An attachment body 450 is formed on the attachment surface S. As shown in FIG. In this embodiment, the adhering body 450 is formed in a shape resembling a flower. In addition, when the present pusher 700 is stored at this time, it is erected with a cap 500 as shown in FIG.

As described above, in the extrusion device 700, the ejection region is formed outside the contact portion 164 of the attachment surface S, so that the content can be obtained without increasing the dimension in the direction orthogonal to the extrusion direction. A discharge area capable of discharging the substance 400 is ensured in the discharge region outside the contact portion 164, and the content 400 is adhered to the adhered surface through the gap C toward the discharge region, that is, along the discharge direction. Since the content 400 flows so as to spread over the S, the content 400 can be changed into various shapes in the ejection region outside the contact portion 164 by adjusting the pushing amount of the pushing member 200 (discharge amount of the content 400). It is possible to In other words, the ejection area is formed outside the contact portion 164 on the attachment surface S, and the content is directed outward along the attachment surface S so as to go to the ejection area through the gap C. By ejecting the substance 400, both avoidance of enlargement in the direction orthogonal to the axis and flexible change of the outer shape of the adhering body 450 are achieved.

In addition, in the pusher 700 , the content 400 flowing outward on the adherend surface S through the gap C contacts the regulating surface 165 . In the present embodiment, the defining surface 165 has a shape that inclines toward the outside toward the adherend surface S in the contact state, so that the content 400 that spreads outward through the gap C is It is guided by the regulating surface 165 so as to be pressed toward the surface S to be adhered. For this reason, the content 400 flowing on the adherend surface S so as to spread along the ejection direction receives from the adherend surface S a greater frictional resistance. Therefore, the adherence of the contents 400 to the adherend surface S is improved. Further, the content 400 flowing outward on the attachment surface S through the gap C contacts the defining surface 165 and also contacts the opposing surface 163c. In the present embodiment, the opposing surface 163c is set to a shape in which the gap C is gradually increased from the inner side to the outer side in the direction parallel to the ejection direction. The volume of the content 400 discharged to the outside of the contact portion 164 increases along the line. Therefore, the contact area between the content 400 and the adherend surface S is increased, so that the adherence of the content 400 to the adherend surface S is further improved.

Further, when the ejection part 160 is separated from the attachment surface S, shear resistance acts on the content 400 along the outer surface 163 b of the gap forming part 163 . More specifically, the shear resistance acts along a surface that includes each outer surface 163b and is continuous over the entire circumferential direction. Therefore, in addition to the portion in contact with the outer side surface 163b of the gap forming portion 163, the attached body 450 also has a portion located between the outer side surfaces 163b adjacent to each other in the circumferential direction. An inner surface is formed in a shape that gradually goes inward as it goes. Therefore, for example, even if the adhered body 450 is formed on the inner surface of the toilet bowl and the water stream collides with the adhered body 450, the inner surface of the attached body 450 will be separated from the water flow by the collision of the water stream with the inner surface of the attached body 450. Since the resistance received is suppressed, separation from the inner surface of the toilet bowl (attachment surface S) of the attached body 450 existing downstream from the inner surface is suppressed.

In addition, in the present embodiment, since the gap forming portion 163 has an inner side surface 163a that is curved to be convex toward the inside, the inner side surface 163a of each gap forming portion 163 contacts the surface S to be adhered. The content 400 directed toward the discharge area outside the contact portion 164 is smoothly guided to the gaps C on both sides of the inner side surface 163a in the circumferential direction by the inner side surface 163a of the gap forming portion 163 .

<3-2-3. Rotating operation after pushing operation (second and subsequent rotating operations)>
Here, only contents different from the contents described in the above <3-2-1> will be described, and contents similar to the above <3-2-1> will be omitted.

At the end of the pushing operation (the same state as the relationship between the projection 233 and the restricting portion 120 shown in FIGS. 3, 19, etc.), the pushing member 200 is rotated 180 degrees in the normal direction.

During 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 around the central axis of the push shaft portion 220 . In the present embodiment, the second inclined portion 132 and the arc portion 133 are radially retracted from the trajectory drawn by the projection 233 while the extrusion shaft portion 220 rotates around the central axis (while the extrusion member 200 is rotated). 20, contact of the projection 233 with the restricting portion 120 is avoided during this rotating operation. Therefore, while the pushing member is rotated by 180 degrees in the forward rotation direction after the pushing operation is finished until the next pushing operation is possible, the bending deformation of the flexible piece 231 is maintained in the released state. creep deformation is suppressed more reliably.

<3-3. Pulling out operation of extruded member>
In the push-out device 700, when the contents 400 in the container 110 are all pushed out by alternately repeating the rotation operation and the push-in operation in the manner described above, that is, when the push-out is performed eight times, the sticky substance cartridge 20 are used.

After that, the pushing member 200 is pulled out from the housing member 100 in the direction opposite to the pushing direction. Here, each protrusion 233 is connected to the flexible piece 231, and the restricting portion 120 has a protrusion pressing portion (each of the inclined portions 131 and 132), so that the push-out member 200 can be easily pushed out from the accommodating member 100. It can be pulled out. Specifically, when the pushing shaft portion 220 is pulled out from the accommodating portion 110 in the direction opposite to the pushing direction, the projection pressing portion presses the projection 233 radially inward, thereby bending the flexible piece 231 and deforming it. As a result, the protrusion 233 is displaced to the inside of the inner peripheral surface 127a (the inner edge portion 121) of the enclosing portion 127. As shown in FIG. 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 out the pushing member 200 in the direction opposite to the pushing direction.

Each flexible piece 231 has a shape extending in the circumferential direction from the extrusion shaft portion 220, and the dimension of each flexible piece 231 in the circumferential direction is set larger than the dimension of the flexible piece 231 in the central axis direction. It is Therefore, it is necessary to arrange a plurality of projections 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 direction of the central axis, and to pull out the extrusion member 200. It is possible to reduce the force. Specifically, since the dimension of each flexible piece 231 in the circumferential direction is set larger than the dimension of the flexible piece 231 in the direction of the central axis, when arranging the plurality of protrusions 233 along the direction of the central axis, is avoided, and each flexible piece 231 has a shape that connects to the extrusion shaft portion 220 at one end side in the circumferential direction. Securing a larger dimension in the direction (circumferential direction) connecting the extrusion shaft portion 220 and the protrusion 233 of each flexible piece 231 than in the case of having a shape connected to the extrusion shaft portion 220 at one end side in the central axis direction, that is, , the force required to displace each protrusion 233 radially inward can be reduced.

In addition, since each projection 233 has a shape in which the amount of protrusion from the outer peripheral surface of the pushing shaft portion 220 gradually increases in the pushing direction, the pushing member 200 can be pulled out more easily from the accommodating member 100. . Specifically, when the pushing member 200 is pulled out from the accommodating member 100, the projection 233 is pushed radially by the projection pressing portion (the inclined portions 131 and 132) as the pushing shaft portion 220 is displaced in the direction opposite to the pushing direction. is gradually pressed inward, that is, the bending (pull-out resistance) of the flexible piece 231 gradually increases, so that the push-out member 200 can be easily pulled out from the housing member 100 .

Furthermore, each protrusion 233 has a shape in which the amount of protrusion from the outer peripheral surface of the push shaft portion 220 gradually decreases as it goes from the fixed end side of the flexible piece 231 toward the free end side (in the direction opposite to the forward rotation direction). , the contact area between the projection 233 and the projection pressing portion during the pulling operation of the pushing member 200 becomes smaller. Therefore, the pushing member 200 can be pulled out from the housing member 100 more easily.

Further, in the present embodiment, the projection pressing portion has a shape that gradually inclines toward the inside in the radial direction as it goes in the direction opposite to the extrusion direction. Therefore, as the pushing shaft portion 220 is displaced in the direction opposite to the pushing direction, the projection 233 is gradually pushed inward in the radial direction by the projection pushing portion. is gradually increased, the operation of pulling out the pushing member 200 from the accommodating member 100 becomes easier. In addition, since the projection pressing portion has a shape that is continuously connected in the circumferential direction except for the avoiding portion 141, regardless of the angular relationship between the restricting portion 120 and the pushing shaft portion 220, the pulling operation of the pushing member 200 is facilitated. Become.

In addition, in the present embodiment, since the blocking portion 240 is connected to the inner peripheral surface of the push shaft portion 220, the breakage of the bend piece 231 during the pulling operation is suppressed, and the lengthwise direction of the bend piece 231 (the push shaft By increasing the dimension of the direction connecting the portion 220 and the protrusion 233 , the pull-out resistance when the push-out member 200 is pulled out from the housing member 100 can be reduced. Specifically, as shown in FIG. 18 , the rear end portion of the projection 233 in the forward rotation direction contacts the blocking portion 240 so that the projection 233 is fully radially inwardly of the outer peripheral surface of the extrusion shaft portion 220 . Therefore, even if the lengthwise dimension of the flexible piece 231 is increased, the bending stress generated at the boundary between the flexible piece 231 and the pushing shaft portion 220 is bent. increase is suppressed. Therefore, by increasing the longitudinal dimension of the flexible piece 231, the pull-out resistance is reduced, and by suppressing an increase in the bending stress generated at the boundary between the flexible piece 231 and the extrusion shaft portion 220, breakage of the flexible piece 231 is suppressed. , can be compatible.

In addition, each flexible piece 231 is arranged such that the distance between the rear end portion of the flexible piece 231 in the pushing direction and the rear end side facing portion 224 is greater than the gap h1 between the front end portion of the bending piece 231 in the pushing direction and the front end side facing portion 223 . It has a shape that reduces the gap h2. Therefore, when the protrusion 233 abuts against the receiving portion 122 due to 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 from the accommodating member 100. 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 pushing direction tip portion of the bending piece 231 and the front end side facing portion 223. Therefore, compared to the case where the sizes of both gaps are the same, the direction opposite to the push-out direction of the flexible piece 231 when the projection 233 receives the reaction force from the receiving portion 122 when the projection 233 contacts the receiving portion 122 Further, a large amount of displacement (bending) of the bending piece 231 in the pushing direction when the pushing member 200 is pulled out from the housing member 100 is ensured.

After the pushing member 200 is pulled out, the housing member 100 and the cap 500 are discarded. On the other hand, the pushing member 200 and the cap 500 can be reused when another adhesive cartridge 20 is used.

<4. Features>
The following effects can be obtained with the pushing tool 700 according to the present embodiment.
(1) As described above, the pushing member 200 is configured to push out the contents while rotating by 180 degrees. Since the shape of is circular in plan view, when the pushing member is rotated, there are cases where it is difficult to know how much it has been rotated. Therefore, in the present embodiment, since the grasping portion 210 is formed in a disc shape, the shape in plan view becomes linear (see FIG. 25). can be easily visually recognized.

(2) Since the recessed portion 212 is formed in the grip portion 210, fingers can be easily fitted into the grip portion 210, and the grip portion 210 can be firmly gripped.

In addition, as shown in FIG. 24, in the cross section perpendicular to each surface on which the recess 212 is formed in the grip portion 210, the surface from each surface to the flange portion 215 passing through the neck portion 214 is an arc-shaped concave surface. Since it is formed, there is an advantage that the finger can be easily fitted to this portion. In other words, the surface from the neck portion 214 to the flange portion 215 is a curved surface that is convex toward the rotating shaft side. Further, as shown in FIG. 25, the neck portion 214 has an elliptical cross section in plan view, whereas the flange portion 215 has a circular shape. There is an advantage that it is easy to apply force to the flange portion 215 when performing. In other words, the grip portion 210 of the present embodiment can make it possible to easily visually recognize how far it is rotated, and to improve the easiness of gripping and pushing during operation.

(3) Since the pushing member 200 is made of a flexible resin material, the gripping portion 210 can be torsionally deformed when the gripping portion 210 is gripped and rotated. As a result, part of the force acting on the gripping portion 210 can be absorbed, and it is possible to prevent the force from concentrating on the connecting portion between the gripping portion 210 and the extrusion shaft portion 220 to cause breakage.

In addition, since the maximum outer peripheral length of the neck portion 214 around the rotation axis is smaller than the maximum outer peripheral length of the grip portion 210, the neck portion 214 can be more easily deformed. Furthermore, although the flange portion 215 is formed below the neck portion 214, since the flange portion 215 is difficult to deform, the force acting on the grip portion 212 can be made to act on the neck portion 214 easily. 214 can be made more deformable. Further, the hollowness of neck 214 makes neck 214 more susceptible to deformation. As the neck 214 deforms, the energy is absorbed by the neck 214, so that the force applied to the pusher shaft 220 tends to be reduced.

<5. Variation>
Although one embodiment of the present invention has been described above, the present invention is not limited to the above-described embodiment, and various modifications are possible without departing from the scope of the invention. For example, the following changes are possible. Also, the gist of the following modified examples can be combined as appropriate.

(1) As shown in FIG. 26, a projection 216 can be formed in the recess 212 of the grip portion 210 . As a result, it plays a role as a non-slip when a finger comes into contact with it. However, the shape and number of protrusions 216 are not particularly limited, and various modes are possible. For example, as the protrusion 216, characters indicating a product name can be employed, and the characters can be formed in a convex shape to prevent slippage.

(2) The shape of the grip portion 210 is not particularly limited. First, the grip portion 210 may have a shape other than a circular shape when viewed from the front, and may have various shapes such as an elliptical shape, a polygonal shape, and an irregular shape. Moreover, the cross-sectional shape of the grip part 210 does not have to be a plate-like shape as in the above embodiment, and may be any shape other than a circular shape so that the rotational position when rotated can be roughly recognized. For example, as shown in FIG. 27(a), the distance from the rotation axis X of the pushing member 200 to the first point A on the outer edge of the grip portion 210 and the distance from the rotation axis X to the second point B are different. It is good if there is The second point B is different from the first point A, and is located, for example, at a position shifted by 90 degrees from the first point. Such a shape includes an ellipse, but other shapes may be used. For example, a shape in which narrow portions 219 protrude from both sides of a central portion 218 of a cross-sectional shape as shown in FIG. 27(b). may be

(3) In the above embodiment, the neck portion 214 and the flange portion 215 are hollow, but at least one of them may be solid.

(4) The configuration of the pushing tool 700 other than the grip part 210 is not particularly limited, and the pushing operation is performed while rotating the pushing member 200 by a predetermined angle, so that the contents can be discharged by a predetermined amount. If there is, it is not particularly limited.
