  In the extrusion tool as described in Patent Document 1, it is difficult to stabilize the insertion posture of the extrusion member with respect to the accommodation member due to the rattling of the extrusion member with respect to the accommodation member, particularly when the extrusion member is attached to the accommodation member. It may become. Specifically, since the outer diameter of the extruded shaft portion is set to be smaller than the inner diameter of the housing portion, the shaft orthogonal to the central axis of the housing portion with respect to the housing portion of the extruded shaft portion when the push member is attached to the housing member The displacement in the orthogonal direction and the inclination of the central axis of the extruded shaft portion with respect to the central axis of the housing portion are likely to occur, and this makes the insertion posture of the extruded shaft portion with respect to the housing member at the time of mounting unstable.

  An object of the present invention is to provide an extrusion device capable of easily attaching an extrusion member to a housing member.

  In order to solve the above-mentioned problem, it is conceivable to set the inner diameter of the accommodating portion equal to the outer diameter of the extruded shaft portion. However, in such a case, the contact area between the housing portion and the extruded shaft portion at the time of mounting is increased, so that the resistance when the extruded shaft portion is inserted into the housing portion is remarkably increased, and the mounting is difficult. There is a fear.

  Then, this invention is an extrusion instrument which can extrude a container, Comprising: The housing member which can accommodate the said housing body and can discharge the said housing body, and pushes out the said housing body from the said housing member An extruding member, and the accommodating member has a cylindrical inner peripheral surface, accommodates the accommodating body, and is disposed at one end of the accommodating portion with respect to the central axis direction of the accommodating portion. A receiving portion having an inner peripheral surface that is connected and capable of receiving the pushing member, a discharge portion that is connected to the other end side of the receiving portion and discharges the receiving body in the central axis direction of the receiving portion; The pushing member has a cylindrical outer peripheral surface that can be inserted into the housing portion via the receiving portion along an extrusion direction from one end side to the other end side of the housing portion. And having a shape that allows the container to be extruded. The extrusion shaft portion and each of the outer circumferential surfaces of the extrusion shaft portion protrude outward from an area separated from each other in the circumferential direction of the extrusion shaft portion in an axis orthogonal direction perpendicular to the central axis direction of the extrusion shaft portion. A plurality of press contact portions that can be press-contacted to the inner peripheral surface of the receiving portion, and each press contact portion has a distal end portion of the extrusion shaft portion in the extrusion direction along the extrusion direction in the reception portion. An extrusion device is provided that has a shape that continues to be pressed against the inner peripheral surface of the receiving portion simultaneously while the tip portion is inserted for a predetermined stroke after being inserted.

  In the present invention, when the extrusion member is attached to the housing member, that is, while the tip end portion of the extrusion shaft portion is inserted into the receiving portion along the extrusion direction, Since each press contact part continues to press simultaneously with the inner peripheral surface of the receiving part at a plurality of locations in the entire circumference, while suppressing a significant increase in resistance when the push member is attached to the storage member, Displacement (rattle) of the pushing member in the direction perpendicular to the axis and inclination of the center axis of the pushing shaft portion with respect to the center axis of the housing portion can be suppressed. Therefore, the insertion posture of the pushing member with respect to the housing member at the time of mounting that is particularly likely to be unstable is stabilized.

  In this case, the plurality of press contact portions have three or more press contact portions, and each press contact portion is a portion of the extrusion shaft portion that is spaced apart from each other at an interval of less than 180 degrees in the circumferential direction of the extrusion shaft portion. It is preferable to be provided.

  If it does in this way, the insertion attitude | position of the extrusion member with respect to the accommodating member at the time of the said mounting will be stabilized further.

  Specifically, it is preferable that each pressure contact portion is provided in a portion of the extruded shaft portion that is spaced apart from each other at equal intervals in the circumferential direction of the extruded shaft portion.

  If it does in this way, the insertion attitude | position of the extrusion member with respect to the accommodating member at the time of the said mounting | wearing will further be stabilized.

  In the present invention, the dimension in the extrusion direction of each press contact portion is set to be larger than the dimension in the extrusion direction of the inner peripheral surface of the receiving portion, and the inner peripheral surface of the housing portion is the extrusion shaft. It is preferable to have a shape that is spaced apart from each press contact portion in the direction perpendicular to the axis while the portion is displaced along the extrusion direction.

  In this way, the insertion posture of the pushing member relative to the housing member at the time of mounting is stabilized, and the insertion resistance at the time of pushing operation of the pushing member along the pushing direction of each pushing member after the respective press contact portions pass through the receiving portion. The increase can be suppressed. Specifically, the dimension in the extrusion direction of each press-contact portion is set to be larger than that of the inner peripheral surface of the receiving portion, and the inner peripheral surface of the housing portion is between the displacement of the extrusion shaft portion along the extrusion direction. The plurality of press contact portions are simultaneously pressed against the inner peripheral surface of the receiving portion while passing through the receiving portion at the time of mounting. At the time of pushing operation after passing through, the inner circumferential surface of the housing portion is not pressed simultaneously. Therefore, the insertion posture of the pushing member with respect to the housing member at the time of mounting is stable, and an increase in insertion resistance of the pushing member into the housing portion at the time of pushing operation after each press contact portion passes through the receiving portion is suppressed. .

  In this case, the housing member further includes a housing body pressing member that is disposed in the housing portion and is capable of pressing the housing body in the extrusion direction by being pressed by the extrusion shaft portion in the extrusion direction, The container pressing member is connected to the close contact portion having an outer peripheral surface that keeps in close contact with the inner peripheral surface of the storage portion while being pressed by the extrusion shaft portion along the extrusion direction, and the close contact portion. It is preferable to have the fitting part which has a shape which can be fitted with the front-end | tip part of an extrusion shaft part.

  If it does in this way, at the time of pushing operation of the extruding member after the tip part of the extruding shaft part fits into the fitting part, the extruding member is separated from each other in the extruding direction among the extruding member by the accommodating member. Since it is supported, the attitude | position of the extrusion member at the time of pushing-in operation is stabilized. Specifically, at the time of pushing operation of the pushing member after the leading end portion of the pushing shaft portion is fitted to the fitting portion, the leading end portion of the pushing shaft portion is accommodated via the fitting portion and the close contact portion of the container pressing member. Since the other part of the extruded shaft portion is in close contact with the receiving portion and is in contact with the receiving portion, the displacement of the extruded member relative to the housing member in the direction perpendicular to the axis or the center of the housing portion of the central shaft of the extruded shaft portion Tilt with respect to the axis is suppressed.

  Furthermore, in this case, the container pressing member is disposed at a position where the distal end portion of the container pressing member in the pushing direction comes into contact with the container in the container, and each press contact portion is formed by the extrusion shaft portion. It is preferable to have a shape that continues to be pressed against the inner peripheral surface of the receiving portion at the same time until the tip portion in the pushing direction is fitted into the fitting portion.

  If it does in this way, the insertion attitude | position with respect to the accommodating member of the extrusion member after the front-end | tip part of an extrusion shaft part is inserted in a receiving part until it fits in the fitting part of a container press member is stabilized.

  As described above, according to the present invention, it is possible to provide an extrusion device capable of easily attaching the extrusion member to the housing member.

It is set smaller than the distance. For this reason, the protrusion 233 located in the accommodating portion 110 among the plurality of protrusions 233 comes into contact with the inclined portions 131 and 132 when the pushing shaft portion 220 is displaced in the direction opposite to the pushing direction. In other words, each of the inclined portions 131 and 132 has a shape capable of pressing the protrusion 233 toward the radially inner side of the extrusion shaft portion 220 when the extrusion shaft portion 220 is displaced in the direction opposite to the extrusion direction. (1st protrusion part press part) "is comprised. Further, the inner diameter of the surrounding portion 127 is set smaller than the outer diameter of the contact portion 181 of the plug member 180. For this reason, the restricting portion 120 also has a function of restricting displacement (detachment from the accommodating portion 110) in the direction opposite to the pushing direction 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 from the central axis of the push shaft 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 retracted in the radial direction from the locus drawn by the protrusion 233 while the push-out shaft portion 220 rotates around the central axis (while the push-out member 200 is rotated). Have a shape to

  In the present embodiment, the pushing member 200 further includes a plurality of press contact portions 250, a raised portion 260, and leg portions 270.

  Each press-contact portion 250 presses against the inner peripheral surface 127 a of the restricting portion 120 when the push-out member 200 is attached to the housing member 100. The plurality of press contact portions 250 protrude outward in the radial direction (axial orthogonal direction) of the extruded shaft portion 220 from a portion of the outer peripheral surface of the extruded shaft portion 220 that is separated from each other in the circumferential direction of the extruded shaft portion 220. It has a shape that can be pressed against the inner peripheral surface 127 a of the portion 120. The dimension from the central axis of the extruded shaft portion 220 to the radially outer end portion of each press contact portion 250 is set to be smaller than the radius of the accommodating portion 110.

  As shown in FIG. 14, each press-contact portion 250 is regulated while the tip 221 of the extrusion shaft portion 220 is inserted into the regulation portion 120 along the extrusion direction and the tip 221 is inserted for a predetermined stroke. It has a shape that continues to press against the inner peripheral surface 127a of the portion 120 simultaneously. As shown in FIGS. 1, 12, and 13, the two press contact portions 250 adjacent to each other among the four press contact portions 250 have the bending pieces 231 that connect the most advanced bulge portion 232 f and the extrusion shaft portion 220. It has a shape extending along the extrusion direction from a portion surrounding the positioned opening 222. The remaining two pressure contact portions 250 of the four pressure contact portions 250 are formed of a bent piece 231 that connects the bulging portion 232 located on the most distal side in the extrusion direction and the extrusion shaft portion 220 in the second bulge portion group. It has a shape extending along the extrusion direction from a portion surrounding the positioned opening 222. That is, in this embodiment, each press contact portion 250 has the foremost bulged portion 232f abutting against the lower receiving portion 123 after the distal end portion 221 of the extruded shaft portion 220 is inserted into the restricting portion 120 along the extruding direction. Until the inner circumferential surface 127a of the restricting portion 120 is continuously pressed.

  The raised portion 260 has a shape that protrudes (projects) radially outward from the outer peripheral surface of the extruded shaft portion 220. The raised portion 260 has a shape extending along the central axis direction of the extruded shaft portion 220. The raised portion 260 is provided at a portion between the first bulge portion group and the second bulge portion group on the outer peripheral surface of the extruded shaft portion 220. In the present 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 includes the rear end portion of the first bulge portion group and the second bulge portion group in the clockwise direction in plan view on the outer peripheral surface of the extruded shaft portion 220. It is connected to the part between the front-end | tip part. 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 distal end portion 221 side of the extrusion shaft portion 220 than the most advanced bulge portion 232f. Has a shape extending along the extrusion direction. For this reason, the front-end | tip part of the extrusion direction among the 1st protruding parts 261 overlaps with each press-contact part 250 in the circumferential direction of the extrusion shaft part 220. That is, in the present embodiment, the distal end portion of the first raised portion 261 also functions as a “pressure contact portion” when the pushing member 200 is attached to the housing member 100.

  As shown in FIG. 13, the second bulging portion 262 includes a distal end portion of the first bulge portion group and a second bulge portion group in the clockwise direction in a plan view on the outer peripheral surface of the extruded shaft portion 220. It is connected to a portion between the rear end portion. The second raised portion 262 extends in the extrusion direction from the rear end portion (upper end portion in FIG. 10) of the extrusion shaft portion 220 to the position spaced in the circumferential direction from the distal end portion in the extrusion direction of the most advanced bulge portion 232f. It has the shape extended along.

  In the present embodiment, the lower-side surrounding portion 128 and the upper-side surrounding portion 129 are formed with recesses 143 and 144 that can be engaged with the raised portions 261 and 262, respectively. Each recessed part 143,144 has a shape which becomes depressed toward the outer side of the said radial direction from parts other than the said recessed part 143,144 among the internal peripheral surfaces 127a of the surrounding part 127. FIG. The concave portion 143 has a shape extending continuously along the central axis direction so as to reach the other end of the lower-side surrounding portion 128 in the central axis direction of the surrounding portion 127, and the concave portion 144 is formed of the surrounding portion 127. It has a shape that continuously extends along the central axis direction so as to extend from one end to the other end of the upper-side surrounding portion 129 in the central axis direction. Each of the recesses 143 and 144 has a protrusion in the radial direction when the primary insertion protrusion 233a and the restricting portion 120 are in the specific angular relationship (when the primary insertion protrusion 233a and the avoiding portion 141 are aligned in the radial direction). It is formed at a position facing the parts 261 and 262.

  Each of the raised portions 261 and 262 presses radially outward against a portion other than the recesses 143 and 144 and the avoiding portion 141 in the inner peripheral surface 127a (inner edge portion 121) of the surrounding portion 127, and is primary. The insertion protrusion 233a and the avoidance portion 141 have a shape that fits into the recesses 143 and 144 when they are aligned in the radial direction. In the present embodiment, the raised portions 261 and 262 are in a state in which the primary insertion protrusion 233a and the restriction portion 120 have the specific angular relationship from the state in which the primary insertion protrusion 233a is in contact with the lower receiving portion 123 (1 Until the next insertion protrusion 233a and the avoiding portion 141 are aligned in the radial direction), the pushing member 200 is directed in the opposite direction to the forward rotation direction (clockwise direction in plan view) in which the pushing member 200 is rotated about the central axis of the pushing shaft portion 220. Accordingly, the protruding amount from the outer peripheral surface of the extruded shaft portion 220 gradually increases.

  The leg part 270 is a part for specifying the angular relationship between the pushing shaft part 220 and the restricting part 120 when the pushing member 200 is attached to the housing member 100. The leg portion 270 is formed in a portion of the extruded 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. The leg portion 270 has a shape that allows the distal end portion (end portion on the free end side) in the extrusion direction to be displaced inward in the radial direction with the rear end portion (end portion on the fixed end side) in the extrusion direction as a fulcrum. Have As FIG. 14 shows, the leg part 270 has a shape which can pass the inside of the avoidance part 141 along an extrusion direction.

  Next, the usage method of this extrusion tool is demonstrated. When the present extrusion device is used, first, the extrusion member 200 is attached to the housing member 100. Then, by alternately repeating the rotation operation and the pushing operation, the container 400 is pushed out from the housing member 100 in a plurality of times. Specifically, the container 400 is pushed out by one rotation operation and one push operation. When the extrusion is completed a plurality of times (when all of the housing body 400 in the housing member 100 is pushed out), the pushing member 200 is pulled out from the housing member 100, and the housing member 100 is discarded. Hereinafter, it demonstrates in order from mounting | wearing to the accommodating member 100 of the extrusion member 200. FIG.

(1) Mounting of the pushing member 200 to the housing member 100 First, the pushing member 200 is mounted to the housing member 100. Specifically, when the angular relationship between the extruded shaft portion 220 and the restricting portion 120 is such that the leg portion 270 is positioned in the avoiding portion 141 (the angular relationship in FIGS. 12 to 14), the extruded shaft portion 220 is It inserts in the accommodating member 100 along an extrusion direction. At this time, as shown in FIG. 14, after the start of insertion of the tip 221 of the extrusion shaft portion 220 into the restriction portion 120, the four pressure contact portions 250 that are separated from each other at intervals of 90 degrees in the circumferential direction. Are continuously pressed against the inner peripheral surface 127a. Therefore, the displacement (rattle) of the pushing member 200 with respect to the housing member 100 in the axis orthogonal direction and the inclination of the center axis of the pushing shaft portion 220 with respect to the center 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 that is particularly likely to become unstable is stabilized.

  Further, in the present embodiment, the inner peripheral surface of the accommodating portion 110 has a shape that is spaced apart 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 is simultaneously pressed against the inner peripheral surface 127a of the restriction portion 120 while passing through the restriction portion 120 at the time of mounting, while 250 is the inner periphery of the accommodating portion 110 during a pushing operation after passing through the restriction portion 120. Do not press against the surface 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 pushing operation after each press contact portion 250 passes through the restricting portion 120. Increase in resistance is suppressed.

  Further, when the foremost bulged portion 232f comes into contact with the lower stage receiving portion 123, the further pushing operation of the pushing member 200 is restricted, whereby the mounting is completed. At this time, the bulging portion 232 located behind one of the most advanced bulging portions 232f in the extrusion direction (the bulging portion 232 located on the most distal side in the extrusion 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 restricting portion 120 at the same time until the most advanced bulge portion 232f contacts the lower stage receiving portion 123. In addition, the tip portion of the first raised portion 261 is also in pressure contact with the inner peripheral surface 127a of the lower-side surrounding portion 128.

  Here, when the mounting is completed (see FIG. 15), the foremost bulged portion 232f, that is, both the protrusion 233 and the overhang portion 234 abut against the lower tier receiving portion 123, and therefore abut against the lower tier receiving portion 123. The area of the part is sufficiently secured. For this reason, it is possible to effectively prevent the pushing member 200 from being accidentally pushed in after the mounting is completed, and the reaction force received by the projection 233 from the lower receiving portion 123 when the mounting is completed is reduced. Is also suppressed. Note that FIG. 15 does not show the completion of the mounting, but the positional relationship between the bulging portion 232 and the receiving portion 122 is the same as that at the completion of the mounting.

  Further, when the mounting is completed, the distal end portion 221 of the extruded shaft portion 220 is fitted 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) Extrusion of the container 400 (2-1) Rotation operation to the first pushing position After the mounting, the most advanced bulging portion 232f is in contact with the lower receiving portion 123. The pushing member 200 is rotated from this state (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 normal rotation direction (clockwise in a plan view), that is, in the direction in which the foremost bulged portion 232f approaches the avoiding 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 come into pressure contact with the inner peripheral surface 127a of the lower-stage surrounding portion 128, and the second raised portion 262 comes into pressure contact with the inner peripheral surface 127a of the upper-stage surrounding portion 129. Keep doing. When the 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-stage surrounding portion 129, the boundary is stretched during the subsequent rotation operation of the pushing member 200. The protruding portion 234 is continuously pressed inward in the radial direction. In other words, in the present embodiment, the boundary between the first step portion 125 and the upper-side surrounding portion 129 presses the bulging portion 232 inward in the radial direction “the bulging portion pressing portion 142 (the protruding portion pressing portion 142). Is configured. In addition, the dimension in the extrusion direction of the bulging part pressing part 142 is set to be equal to or less than the dimension in the central axis direction between the protrusions 233. In this embodiment, after the contact of the overhang 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 grows gradually.

  Further, when the protrusion 233 (primary insertion protrusion 233a) of the foremost bulged portion 232f abuts on the first step portion 125, further rotation operation of the push-out member 200 in the normal rotation direction is restricted, thereby rotating The operation is complete. At this time, as shown in FIGS. 16 to 18, the primary insertion protrusion 233 a is accommodated in the avoidance portion 141. For this reason, the pushing-in operation to the extrusion direction of the extrusion member 200 is attained. As described above, in the present extrusion device, the pushing position defining portion 230 capable of defining one pushing operation is connected to the pushing shaft portion 220 for pushing out the container 400, and the restricting portion 120 serves as the pushing position defining portion. 230 includes a bulging portion pressing portion 142 having a shape capable of pressing 230 toward the inner side in the direction perpendicular to the axis, so that the structure 400 of the pushing member 200 is simplified and the container 400 is pushed out in a plurality of times. Is possible.

  In the present embodiment, since the raised portions 261 and 262 are fitted into the recesses 143 and 144 when the rotation operation is completed, a so-called click feeling is given to the operator. Specifically, the push-out 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 mounting is completed) until the primary insertion protrusion 233a is within the avoidance portion 141. In the meantime, the raised portions 261 and 262 are kept in pressure contact with the inner peripheral surface 127a of the restricting portion 120, so that the operator feels resistance to the rotation operation during this time, while the primary insertion protrusion 233a is within the avoidance portion 141. Since the raised portions 261 and 262 are fitted into the recessed portions 143 and 144 (when the pushing operation becomes possible), the resistance is reduced. This change (reduction) in resistance during the 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 possible.

  Moreover, in this embodiment, since each protruding part 261,262 has a shape where the protrusion amount from the outer peripheral surface of the extrusion shaft part 220 increases gradually toward the reverse direction to the normal rotation direction, each protruding part 261, The resistance when rotating the push-out member 200 in the direction opposite to the forward rotation direction than the resistance when turning the push-out member 200 in the forward rotation direction from the state in which the H.262 is fitted in each of the recesses 143 and 144 Becomes larger. For this reason, it is suppressed that the pushing member 200 is rotated in the reverse direction from the state in which the raised portions 261 and 262 are fitted in the recessed portions 143 and 144.

  In the present embodiment, since 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, the bending of the bending piece 231, that is, the bending piece 231 and The pushing position can be effectively defined while suppressing an increase in bending stress generated at the boundary with the extruded shaft portion 220. Specifically, a protrusion 233 having a relatively large protruding amount is connected to the tip end portion (the end portion on the free end side) of the bending piece 231, that is, the bending portion 231 having the largest bending amount. A protruding portion 234 having a relatively small protruding amount is formed at a portion between a base end portion (an end portion on the fixed end side) and the distal end portion, that is, a portion of the bending piece 231 that is less bent than the distal end portion. While being connected, the extrusion shaft portion is suppressed while suppressing an increase in the deflection of the bending piece 231 required to displace the entire bulging portion 232 inward in the direction perpendicular to the axis from the inner edge portion 121 of the restriction portion 120. By effectively securing the contact area between the bulging portion 232 and the receiving portion 122 when 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 with the lower receiving portion 123 in the pushing direction, and the tertiary insertion protrusion 233c overlaps with the upper receiving portion 124 in the pushing direction.

  Then, the contact portion 164 of the discharge unit 160 is brought into contact with the adherend surface S. At this time, since all the abutting portions 164 abut against the adherend surface S at the same time, the posture of the extrusion device when the abutment portions 164 are abutted against the adherend surface S is stabilized. More specifically, since the contact surface that is the tip of each gap forming portion 163 is formed in a plane that can come into surface contact with the adherend surface S, each contact surface and the adherend surface S The contact area is ensured. Therefore, the posture of the extrusion tool when these contact surfaces are brought into contact with the adherend surface S is stabilized. In this state, a discharge area in which the container 400 (adhesive body 400) can be discharged is formed outside the contact portion 164 in the adherend surface S. Note that 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 within the avoidance portion 141. 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. If it does so, the plug member 180 will be pressed by the extrusion shaft part 220 along an extrusion direction, and, thereby, the container 400 will be discharged from the discharge part 160 to a discharge area | region. Specifically, the container 400 in the container 110 comes out of the outlet in the partition 161 along the extruding direction, and then comes into contact with the region inside the contact portion 164 in the adherend surface S. When the pushing member 200 continues to be pushed thereafter, the container 400 moves in the circumferential direction toward the discharge region formed outside the contact portion 164 of the adherend surface S as shown in FIG. It is discharged radially only from a plurality of gaps C intermittently arranged. Specifically, the adhesive body 400 is blocked from flowing on the adherend surface S toward the outside of the contact portion 164 in the region where each gap forming portion 163 exists, while the gap C is formed. In the region, it is allowed to flow outward along the adherend surface S through the gap C. More specifically, in the region where each gap forming portion 163 exists, the adhesive body 400 is directed toward both gaps C formed on both sides in the circumferential direction of the gap forming portion 163 by the inner surface 163a of the gap forming portion 163. In the region where the gap C is formed, the one that flows from the inner region of the contact portion 164 toward the gap C and the one that is guided to the gap C by the inner side surfaces 163a on both sides of the gap C. And the fluid flow so as to spread outward along the adherend surface S through the gap C. In FIG. 21, only the container 400 discharged from the single gap C is shown for explanation.

  When the pushing operation of the pushing member 200 is continued, the adhesive 400 that has flowed out to the outside of the contact portion 164 through each gap C has the surface to be adhered S on the discharge area as shown in FIG. It becomes the shape which protrudes from the to-be-adhered surface S, flowing further outward along it. In FIG. 22, only the container 400 discharged from the single gap C is shown.

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

  In addition, while the pushing operation is being performed, the extrusion shaft portion 220 is supported by the housing member 100 at two locations that are separated from each other in the extrusion direction of the extrusion shaft portion 220. Posture is stable. Specifically, the distal end portion 221 of the extruded shaft portion 220 is in close contact with the accommodating portion 110 via the fitting portion 182 and the close contact portion 181 of the plug member 180, and a part of other portions of the extruded shaft portion 220 is Since it contacts the inner peripheral surface 127a of the restricting portion 120, the radial displacement (axial orthogonal direction) of the pushing member 200 relative 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. Is done.

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

  And the protrusion 233 of the most advanced bulge part 232f passes the avoidance part 141, and the bulge part containing the primary insertion protrusion 233a (protrusion 233 located in the front end side of the extrusion direction most among 2nd bulge part groups). 232 comes into contact with the lower receiving portion 123 and includes a bulging portion 232 including a secondary insertion protrusion 233b (protrusion 233 located one rearward in the pushing direction from the most advanced bulging portion 232f in the first bulging portion group). Is in contact with the upper receiving portion 124, further pushing operation of the pushing member 200 is restricted, and thus the pushing operation is completed. At this time, the bulging portion 232 including the primary insertion protrusion 233a is received by the lower receiving portion 123 and the bulging portion 232 including the secondary insertion protrusion 233b is received by the upper receiving portion 124. Compared with the case where only the most advanced bulging portion 232 f 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 comes into contact with the receiving portion 122 is reduced. The Therefore, damage to each bulging part 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 a steady state where no external force is applied to the bending piece 231. Specifically, in the present embodiment, the dimension in the pushing direction of the bulging portion pressing portion 142 is set to be equal to or smaller than the size in the central axis direction between the protrusions 233, and the second inclined portion 132 and the arc portion 133 are set. Has a shape that is radially separated from the protrusion 233, so that after the pushing operation is finished, the pressing of the bulging portion 232f by the bulging portion pressing portion 142 is released, and the bending piece 231 is elastically returned to a steady state. . Therefore, the creep deformation of the bending piece 231 after the end of the pushing operation is suppressed.

  In the present embodiment, the arrangement of the bulging portions 232 is set so that the stroke of the first pressing operation is longer than the strokes of the second and subsequent pressing operations. The amount of the container 400 pushed out from the member 100 becomes larger than the amount of the container 400 pushed out from the container member 100 by the second and subsequent pushing operations. Therefore, it is suppressed that the amount of extrusion by the first pushing operation is less than the amount of pushing by the second and subsequent pushing operations due to slight variations in the filling amount of the container 400 into the housing unit 110. For this reason, the pushing amount of the container 400 at the time of each pushing operation is ensured to be a predetermined amount or more.

  When the pushing operation is completed, a shape (for example, a petal) extending in a direction parallel to the discharge direction at a plurality of locations (six locations in the present embodiment) in the discharge area outside the contact portion 164 of the adherend surface S. The adhesive body 400 adheres to the shape.

  Here, in the state shown in FIG. 21 and FIG. 22, the container 400 discharged toward the outside along the adherend surface S from the two adjacent gaps C forms a gap that is located between the gaps C. By flowing so as to wrap around the outside of the part 163, the outer surface 163 b of the gap forming part 163 is contacted. From this state, when the discharge section 160 is moved away 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. An attachment body 450 is formed on the attachment surface S. In the present embodiment, the attachment 450 is formed in a shape simulating a flower. In addition, when storing this extrusion instrument at this time, as FIG. 3 shows, it stands on the mounting base 300. As shown in FIG.

  As described above, in the present extrusion device, since the discharge region is formed outside the contact portion 164 in the adherend surface S, the container body can be obtained without increasing the size in the axis orthogonal direction orthogonal to the extrusion direction. A discharge area capable of discharging 400 is ensured in the discharge region outside the contact portion 164, and the container 400 is attached to the surface S to be attached to the discharge region via the gap C toward the discharge region, that is, along the discharge direction. Since the fluid flows so as to spread, the container 400 is changed into various shapes in the discharge region outside the contact portion 164 by adjusting the pushing amount of the push-out member 200 (discharge amount of the container 400). It becomes possible. In other words, the discharge area is formed outside the contact portion 164 of the adherend surface S, and is accommodated outward along the adherend surface S so as to go to the discharge area via the gap C. By discharging the body 400, both avoidance of enlargement in the direction perpendicular to the axis and flexible change of the outer shape of the attachment body 450 are achieved.

  Further, in the present extrusion tool, 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 regulation surface 165 has a shape that is inclined so as to approach the adherend surface S toward the outside in the abutting state. The guidance is such that the regulation surface 165 is pressed toward the adherend surface S. For this reason, the frictional resistance which the container 400 which flows so that it may spread on the adherend surface S along the said discharge direction receives from the adherend surface S becomes large. Therefore, the adhesion to the adherend surface S of the container 400 is improved. In addition, the container 400 that flows so as to spread outward on the adherend surface S through the gap C contacts the defining surface 165 and also contacts the opposing surface 163c. In the present embodiment, the facing surface 163c is set to have a shape that gradually increases the gap C in the direction parallel to the ejection direction from the inside to the outside. The volume of the container 400 that is discharged to the outside of the contact portion 164 increases. Therefore, since the contact area between the container 400 and the adherend surface S is increased, the adhesion of the container 400 to the adherend surface S is further improved.

  Further, when the discharge part 160 is separated from the adherend surface S, shear resistance acts on the container 400 along the outer side 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 region in the circumferential direction. Therefore, in addition to the portion that has been 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 that are adjacent to each other in the circumferential direction. An inner surface having a shape gradually inward as it goes is formed. Therefore, for example, even when the adherent 450 is formed on the inner surface of the toilet and the water flow collides with the adherent 450, the inner surface is separated from the water flow by the collision of the water flow with the inner surface of the adherent 450. Since the resistance received is suppressed, detachment from the inner surface (attached surface S) of the toilet bowl of the adhering body 450 that is present downstream from the inner surface is suppressed.

  Further, in the present embodiment, the gap forming portion 163 has an inner surface 163a that is curved so as to be convex inward, so that the contact portion S is contacted inside the gap forming portion 163 after contacting the adherend surface S. The container 400 toward the discharge region outside the contact portion 164 is smoothly guided to the gap C on both sides in the circumferential direction of the inner side surface 163a by the inner side surface 163a of the gap forming portion 163.

(2-3) Rotation operation after pushing operation (second and subsequent rotation operations)
Here, only the content different from the content described in the above (2-1) will be described, and the content 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 restricting portion 120 shown in FIG. 3, FIG. 19, etc.), the pushing member 200 is rotated 180 degrees in the forward rotation direction.

  During this rotation operation, the protrusion 233 that has passed through the avoiding portion 141 rotates around the central axis of the push-out shaft portion 220 inside the second inclined portion 132 and the arc portion 133. In the present embodiment, the second inclined portion 132 and the arc portion 133 are retracted in the radial direction from the locus drawn by the protrusion 233 while the push-out shaft portion 220 rotates around the central axis (while the push-out member 200 is rotated). Therefore, the contact of the protrusion 233 with the restricting portion 120 is avoided during the rotation operation (see FIG. 20). Therefore, since the pushing member is rotated 180 degrees in the forward rotation direction until the next pushing operation becomes possible after the pushing operation is finished, the released state of the bending deformation of the bending piece 231 is maintained. Creep deformation of is more reliably suppressed.

(3) Pulling-out operation of pushing member 200 In this pushing tool, when the container 400 in the container part 110 is pushed out by repeating the rotation operation and the pushing operation alternately in the above manner, that is, the pushing operation is performed eight times. Is performed, the adhesive cartridge 20 is used.

  Thereafter, 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 bending piece 231, and the restricting portion 120 has a protrusion pressing portion (inclined portions 131 and 132), so that the pushing member 200 can be easily removed from the housing member 100. It can be pulled out. Specifically, when the extrusion shaft portion 220 is pulled out from the accommodating portion 110 in the direction opposite to the extrusion direction, the bending piece 231 is bent and deformed by the protrusion pressing portion pressing the protrusion 233 toward the inside in the radial direction, Thereby, the protrusion 233 is displaced to the inner side of the inner peripheral surface 127a (inner edge portion 121) of the surrounding portion 127. Therefore, regardless of the angular relationship between the restricting portion 120 and the extrusion shaft portion 220, the extrusion member 200 is pulled out by pulling out the extrusion member 200 in the direction opposite to the extrusion direction.

  In addition, each bending piece 231 has a shape extending in the circumferential direction from the extrusion shaft portion 220, and the dimension in the circumferential direction of each bending piece 231 is set larger than the dimension in the central axis direction of the bending piece 231. Has been. Therefore, it is necessary for the plurality of protrusions 233 to be disposed along the central axis direction of the extrusion shaft portion 220 and for the pulling operation of the extrusion member 200 while avoiding a significant increase in the size of the extrusion shaft portion 220 in the central axis direction. It is possible to reduce the necessary force. Specifically, since the dimension in the circumferential direction of each flexible piece 231 is set larger than the dimension in the central axis direction of the flexible piece 231, when arranging a plurality of protrusions 233 along the central axis direction. The extrusion shaft portion 220 is prevented from being enlarged in the central axis direction, and each bending piece 231 has a shape connected to the extrusion shaft portion 220 at one end side in the circumferential direction. Compared to the case of having a shape connected to the extrusion shaft portion 220 on one end side in the central axis direction, it is possible to ensure a large dimension in the direction (circumferential direction) connecting the extrusion shaft portion 220 and the protrusion 233 among the bending pieces 231. The force required to displace each projection 233 radially inward can be reduced.

  Further, each protrusion 233 has a shape in which the protruding amount from the outer peripheral surface of the extrusion shaft portion 220 gradually increases as it goes in the extrusion direction, so that the extrusion member 200 can be more easily pulled out from the housing member 100. . Specifically, at the time of the pulling operation for pulling out the push member 200 from the housing member 100, the protrusion 233 is radially moved by the protrusion pressing portion (the inclined portions 131 and 132) as the push shaft 220 is displaced in the direction opposite to the push direction. Is gradually pressed inward, that is, the bending (extraction resistance) of the bending piece 231 is gradually increased, so that the operation of pulling out the pushing member 200 from the housing member 100 is facilitated.

  Further, each protrusion 233 has a shape in which the protrusion amount from the outer peripheral surface of the extruded 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). In addition, the contact area between the protrusion 233 and the protrusion pressing portion when the push-out member 200 is pulled out is reduced. Therefore, the pushing member 200 can be more easily pulled out from the housing member 100.

  Moreover, in this embodiment, the protrusion pressing part has a shape which inclines so that it may go to inner side of radial direction gradually as it goes to the opposite direction to an extrusion direction. For this reason, the protrusion 233 is gradually pressed inward in the radial direction by the protrusion pressing portion as the extrusion shaft portion 220 is displaced in the direction opposite to the extrusion direction, that is, the bending of the bending piece 231 (extraction resistance). Therefore, 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 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 restricting portion 120 and the pushing shaft portion 220. Become.

  In the present embodiment, since the blocking portion 240 is connected to the inner peripheral surface of the extrusion shaft portion 220, the longitudinal direction of the bending piece 231 (extrusion shaft) while suppressing damage to the bending piece 231 during the pulling operation. By increasing the dimension in the direction connecting the portion 220 and the protrusion 233, the pulling resistance when pulling out the pushing member 200 from the housing member 100 can be reduced. Specifically, as shown in FIG. 18, when the rear end portion of the protrusion 233 in the forward rotation direction comes into contact with the blocking portion 240, the protrusion 233 is completely inward in the radial direction from the outer peripheral surface of the extrusion shaft portion 220. Therefore, even if the longitudinal dimension of the flexure piece 231 is increased, the flexure of the flexure piece 231, that is, the bending stress generated at the boundary between the flexure piece 231 and the extrusion shaft portion 220 is prevented. Increase is suppressed. Therefore, the pulling resistance is reduced by increasing the longitudinal dimension of the bending piece 231, and the breakage of the bending piece 231 is suppressed by suppressing the increase in bending stress generated at the boundary between the bending piece 231 and the extruded 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 rather than a gap h1 between the leading end portion in the pushing direction of the bending piece 231 and the leading end facing portion 223. It has a shape that reduces the gap h2. Accordingly, 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 pulling when the pushing member 200 is pulled from the housing member 100 is pulled out. Resistance is effectively reduced. Specifically, the gap h2 between the rear end portion and the rear end side facing portion 224 in the pushing direction of the bending piece 231 is smaller than the gap h1 between the front end portion and the front side facing portion 223 of the bending piece 231 in the pushing direction. Therefore, compared with the case where the size of both the gaps is the same, the direction opposite to the pushing direction of the bending piece 231 when the projection 233 receives a reaction force from the receiving portion 122 when the projection 233 contacts the receiving portion 122. And the displacement amount (deflection) in the pushing direction of the bending piece 231 when the pushing member 200 is pulled out from the housing member 100 is ensured to be large.

  Then, after the pulling 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 pressure-sensitive adhesive cartridge 20 is used.

  In addition, it should be thought that the said embodiment disclosed this time is an illustration and restrictive at no points. 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 further includes all modifications within the meaning and scope equivalent to the scope of claims for patent.

  Moreover, the structure of the receiving part 122 is not restricted to the example of the said embodiment. For example, the upper receiving portion 124 of the receiving portion 122 may be omitted, and the receiving portion 122 may be configured by only the lower receiving portion 123.

  Further, the structure of the housing member 100 is not limited to the example of the above embodiment. For example, the restriction part 120 (receiving part 120) may be omitted, and the upper end part of the accommodating part 110 may constitute a “receiving part”. In this case, each pressure contact portion 250 has a predetermined end portion 221 in the accommodating portion 110 after the distal end portion 221 of the extruded shaft portion 220 is inserted into the upper end portion (receiving portion) of the accommodating portion 110 along the extruding direction. While the stroke is inserted, the shape is set so as to continuously press against the inner peripheral surface of the receiving portion.

If it is a site | part to do, it can be provided in arbitrary sites.

  Moreover, the shape of the extrusion shaft part 220 and the accommodating part 110 is not restricted to a cylindrical shape.
