Description

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

  DESCRIPTION OF RELATED ART Conventionally, the extrusion apparatus for extruding the accommodating body accommodated in the accommodating member from the accommodating member by a pushing member is known. For example, Patent Document 1 discloses a drug cartridge device (extrusion device) including a cylinder for containing a fluid adhesive drug (container), a slider disposed in the cylinder, and a pressing tool for pressing the slider. Is disclosed.

  The cylinder is formed in a cylindrical shape and has a housing portion for housing the housing body, and a diverging portion connected to the outer peripheral surface of the housing portion. A discharge port for discharging the container toward the adherend surface (the inner surface of the toilet, etc.) is formed at an end of one side of the container. The diverging portion has a shape surrounding the discharge port. The distal end portion of the diverging portion abuts on the surface to be attached, whereby a space is formed between the surface to be attached and the housing portion.

  The slider is inserted into the housing portion from the opening of the housing portion opposite to the discharge port. The slider can push the container toward the discharge port.

  The pusher is connected to the slider and pushes the slider toward the discharge port along the axial direction of the housing.

  At the time of use of the extrusion device, the pushing tool is pushed by the user into the accommodation portion along the axial direction of the accommodation portion in a state where the distal end portion of the diverging portion abuts on the attachment surface. Then, the slider pushes the container in the housing portion toward the discharge port, and the container is discharged onto the adherend surface through the discharge port in the space defined by the housing portion and the diverging portion. As a result, the container adheres to the portion of the adherend surface surrounded by the divergent portion.

  In the extrusion device as described in Patent Document 1, there is a concern that the slider and the pusher may be separated from the cylinder due to the vibration applied to the extrusion device during transport of the extrusion device or the like.

  Therefore, it is conceivable to provide a protrusion for removal (for example, a protrusion having a shape projecting inward from the storage portion in the radial direction of the storage portion) at the end of the storage portion opposite to the discharge port. . However, when such a projecting portion is provided, when inserting the slider, that is, the extrusion portion capable of extruding the storage body toward the discharge port into the storage portion, the outer peripheral surface of the extrusion portion It may be damaged, which may result in inadequate sealing of the receptacle by the pusher.

  An object of the present invention is to provide an extrusion device capable of suppressing the detachment of the extrusion member from the accommodation member while avoiding damage to the outer peripheral surface of the extrusion part.

  As means for solving the above problems, the present invention is an extrusion device capable of extruding a container, the container member capable of containing the container and discharging the container, and And a pushing member for pushing out the holding body from the holding member, wherein the holding member is formed in a tubular shape and has a holding portion for holding the holding body, and the holding portion is a portion of the holding portion. It has a discharge port formed on one end side for discharging the container, and the pushing member is inserted into the container from the other end of the container with respect to the central axis direction of the container. , And the central axis in the storage unit is maintained while in a state of being in contact with the inner peripheral surface of the storage unit so that the storage unit stored in the storage unit is pushed out toward the discharge port. Be displaced along the direction An accommodating unit, and an operating unit connected to the pushing unit and capable of being operated by the operator so that the pushing unit is displaced toward the discharge port; The locking member has a locking portion for locking the pushing member so as to prevent the pushing member from being detached from the holding portion in a state where the pushing portion is positioned in the holding portion, and the pushing member The locking portion has a locking portion engaged with the locking portion, and the locking portion is outwardly recessed in an axial orthogonal direction which is a direction orthogonal to the central axis direction from the inner peripheral surface of the housing portion. The engaged portion has a shape projecting outward beyond the inner peripheral surface of the accommodation portion in the axial orthogonal direction when no external force is applied to the engaged portion, and the engaged portion When an inward external force acts on the stop in the direction orthogonal to the axis, the axis Elastically deformed inwardly the direction, to provide an extrusion device.

  In the present extrusion device, since the locking portion has a shape which is recessed outward from the inner circumferential surface of the storage portion in the direction orthogonal to the axial direction, the locking portion is the extrusion portion when inserted into the storage portion of the extrusion portion. Damage to the outer peripheral surface is avoided. Furthermore, when the push-out portion is inserted into the storage portion, the locked portion receives the external force inward in the direction orthogonal to the axis from the inner peripheral surface of the storage portion until it reaches the locking portion. It is elastically deformed, and when it reaches the locking portion, the locking portion is engaged by resiliently returning. Therefore, detachment of the push-out member from the housing member due to vibration at the time of transportation or the like of the push-out device is suppressed.

  Further, the engagement portion is gradually directed in the direction away from the extrusion portion in the central axis direction as it goes outward in the axial orthogonal direction, and on the side where the extrusion portion is positioned in the central axis direction It is preferable to have a shape that is curved so as to be convex.

  In this way, when the push-out member is displaced toward the discharge port, the engaged portion is easily elastically deformed, and the push-out member is accommodated in the state where the engaged portion is engaged with the engagement portion. When an external force in the direction of detachment is applied to the push-out member, the engaged portion is less likely to be elastically deformed. Therefore, the insertion of the push-out portion into the storage portion and the operation of pressing the operation portion from the state where the locked portion is engaged with the lock portion become easy, and the detachment of the push-out member from the storage portion is effective. It is regulated.

  In addition, the extrusion member further includes a convex portion provided on a side opposite to the side where the extrusion portion is positioned in the locked portion in the central axis direction, and the convex portion is the extrusion It is preferable that when an external force acts on the member in a direction in which the push-out member separates from the accommodating portion, the portion to be engaged elastically abuts against the inner circumferential surface of the accommodating portion.

  According to this configuration, when an external force acts on the push-out member in a direction in which the push-out member separates from the storage portion, the projection is elastically deformed so as to increase the curvature radius thereof. Since it abuts on the inner circumferential surface of the housing portion, further elastic deformation of the locked portion is suppressed. Thus, the detachment of the pushing member from the housing portion is more reliably suppressed.

  As described above, according to the present invention, it is possible to provide an extrusion device capable of suppressing the detachment of the extrusion member from the accommodation member while avoiding damage to the outer peripheral surface of the extrusion portion.

Is also set large. In the present embodiment, the dimension d1 is 3.7 mm, and the dimension d2 is 1.6 mm. The abutting end portion 123 may be divided into two or more portions separated from each other in the axial orthogonal direction. In this case, the dimension d1 means the dimension from the part closest to the discharge port 115 to the part farthest from the discharge port 115 among the two or more parts.

  The adhesion suppression unit 130 suppresses adhesion of the container 10 to the outer surface of the bottom wall 114. As shown in FIGS. 3 and 4, the adhesion suppressing portion 130 has a plurality of wall portions 131 to 135 connected to a portion of the outer surface of the bottom wall 114 around the discharge port 115.

The wall portions 131 to 135 are arranged at positions mutually separated in the axial orthogonal direction (the radial direction of the bottom wall 114). For example, the dimension between the wall portions is set to about 2 mm.

  As shown in FIG. 3, the dimension of the second wall 132 in the same direction is larger than the dimension of the first wall 131 in the central axis direction. Similarly, the dimension of the third wall 133 in the same direction is larger than the dimension of the second wall 132 in the central axis direction.

In other words, each gap forming portion 122 connects the third wall portion 133 and the fourth wall portion 134. Further, the dimension d1 of each abutting end portion 123 is set to be equal to or larger than the dimension between the wall portions (the third wall portion 133 and the fourth wall portion 134 in this embodiment) adjacent to each other in the axial orthogonal direction. .

  The pushing member 200 has a pushing unit 210 and an operation unit 230.

  The pushing portion 210 keeps the inside of the housing portion 110 in the central axis direction while maintaining the state in which the housing 10 housed in the housing portion 110 is in contact with the inner peripheral surface of the peripheral wall 112 so as to be pushed out toward the discharge port 115. It is possible to displace along The push-out portion 210 can be inserted into the peripheral wall 112 from the other end (upper end in FIG. 2) of the peripheral wall 112 in the central axis direction of the peripheral wall 112. Specifically, the extrusion unit 210 has an outer cylindrical portion 212, a pressing wall 214, and an inner cylindrical portion 216.

  The outer cylindrical portion 212 is formed in a cylindrical shape (hollow shape) and has an outer peripheral surface having a shape along the inner peripheral surface of the peripheral wall 112. As shown in FIG. 7, an annular protrusion 213 is provided on the outer peripheral surface of the outer cylindrical portion 212. The annular protrusion 213 is in close contact with the inner circumferential surface of the peripheral wall 112 when the pushing portion 210 is inserted into the peripheral wall 112.

  The pressing wall 214 has a shape that closes the opening of the outer cylindrical portion 212. The pressing wall 214 is connected to the lower end portion of the outer cylindrical portion 212.

  The inner cylindrical portion 216 is formed in a cylindrical shape having a diameter smaller than the diameter of the outer cylindrical portion 212. The diameter of the inner cylindrical portion 216 is set larger than the diameter of the discharge port 115. The inner cylindrical portion 216 is connected to the upper surface of the pressing wall 214. The inner cylindrical portion 216 has a holding portion 217 that holds the operation portion 230.

  The operation unit 230 is connected to the extrusion unit 210, and is a portion for the operator to operate so that the extrusion unit 210 is displaced toward the discharge port 115. As shown in FIG. 5, the operation unit 230 includes a knob 232, a finger receiver 236, an extension 238, a connected portion 240, a proximity portion 246, a locked portion 248, and a protrusion 250. And.

  The knob 232 is a part for the user to pinch. As shown in FIGS. 5 and 6, the knob portion 232 has a knob body 233 and a non-slip portion 234. The knob main body 233 is formed in a flat plate shape. The non-slip portion 234 has a shape that protrudes from the surface of the knob body 233 and extends linearly along the surface of the knob body 233.

  The finger receiver 236 is connected to the knob 232 and is a part that receives the user's finger. The finger receiving portion 236 has a shape protruding from the surface of the knob main body 233 in a direction orthogonal to the central axis direction (direction orthogonal to the knob main body 233). Specifically, the finger receiving portion 236 has a shape that is curved so as to be convex toward the extrusion portion 210 (downward in FIG. 6) in the central axis direction. As shown in FIG. 6, an end (a lower end of FIG. 6) of the finger receiving part 236 on the side where the extrusion part 210 is located in the central axis direction (the lower end of FIG. 6) The upper end portion of the finger receiving portion 236 from the end portion (upper end portion in FIG. 6) of the knob main body 233 on the opposite side to the side where the extrusion portion 210 is positioned in the central axis direction The dimension h2 up to is larger. In the present embodiment, the dimension h1 is 5.2 mm, and the dimension h2 is 12.2 mm.

  The extension portion 238 has a shape extending downward from the knob portion 232 along the central axis direction. The dimension of the extension portion 238 in the central axis direction is set to an extent that the knob portion 232 is exposed from the housing portion 110 in a state where the pressing wall 214 abuts on the bottom wall 114.

  The connected portion 240 is a portion connected to the inner cylindrical portion 216. As shown in FIGS. 5, 7 and 8, the connected portion 240 has a held portion 242 and an opposing portion 244. The held portion 242 is a portion held by the holding portion 217 of the inner cylindrical portion 216. The held portion 242 is formed in a disk shape. The holding portion 217 holds the held portion 242 from both sides in the central axis direction. The shape of the holding portion 217 and the outside of the annular projection 213 are set such that the holding force of the held portion 242 by the holding portion 217 is larger than the frictional force generated between the pushing portion 210 and the inner circumferential surface of the peripheral wall 112. The amount of protrusion from the outer peripheral surface of the cylindrical portion 212 is set. For this reason, when the external force in the direction in which the operating unit 230 moves away from the pushing unit 210 along the central axis direction acts on the operating unit 230, detachment of the operating unit 230 from the pushing unit 210 is suppressed. The facing portion 244 is provided at a position separated from the held portion 242 in the central axis direction. In the present embodiment, the facing portion 244 is provided above the held portion 242. The facing portion 244 is formed in a disk shape. The outer end portion of the facing portion 244 in the radial direction of the facing portion 244 abuts on the inner circumferential surface of the inner cylindrical portion 216 or places a predetermined gap (for example, about 0.1 mm) with the inner circumferential surface. Are facing each other. That is, in the inner cylindrical portion 216, a portion in contact with the outer end of the facing portion 244 or facing the outer end with a predetermined gap is a position where the operating portion is away from the holding portion 217 in the central axis direction. It corresponds to the "receiving part 218" which receives 230.

  The proximity portion 246 keeps in contact (sliding contact) with the inner peripheral surface of the peripheral wall 112 while the push-out portion 210 is displaced toward the discharge port 115 or has a predetermined gap (for example, about 0.1 mm) with the inner peripheral surface. It is a part that leaves and keeps on facing. The proximity portion 246 has a shape protruding from the extension portion 238 in the axial orthogonal direction (the same direction as the direction in which the finger receiving portion 236 protrudes from the knob main body 233). As shown in FIGS. 5 and 8, in the present embodiment, the proximity portion 246 includes a first overhang portion 246 a projecting from the extension portion 238 to one side in the axial orthogonal direction, and a second overhang portion projecting to the other side. And an overhang portion 246 b. The outer end portions of the projecting portions 246 a and 246 b in the direction orthogonal to the axis are formed in a shape along the inner peripheral surface of the peripheral wall 112. Each overhang portion 246a, 246b is formed in a flat plate shape.

  The locked portion 248 is a portion engaged with the locking portion 113 of the peripheral wall 112. The locked portion 248 has a shape that protrudes from the extension portion 238 in the axial orthogonal direction. In the present embodiment, the to-be-locked portion 248 is a first arm portion 248 a that protrudes to one side from the extension portion 238 in a direction orthogonal to the direction connecting the first overhang portion 246 a and the second overhang portion 246 b; And a second arm 248 b protruding to the other side. As shown in FIG. 7, when no external force is applied to the arms 248 a and 248 b, the arms 248 a and 248 b are outside the inner circumferential surface of the peripheral wall 112 in the axial orthogonal direction (the radial direction). It has an overhanging shape. FIG. 7 shows a state in which the locked portion 248 is engaged with the locking portion 113. The arms 248a and 248b elastically deform inward in the axis orthogonal direction when an inward external force acts on the arm parts 248a and 248b in the axis orthogonal direction. In the present embodiment, the arms 248a and 248b gradually move upward (in the direction of the central axis toward the knobs 232) toward the outer side in the axis orthogonal direction and toward the lower side (in the central axis direction). Is curved so as to be convex on the side where the connected portion 240 is located.

  The convex portion 250 is provided on the upper surface of each of the arm portions 248 a and 248 b of the locked portion 248. When the external force in the direction (upward in FIG. 2) in which the push-out member 200 separates from the storage portion 110 acts on the push-out member 200, the convex portion 250 is elastically deformed when the engaged portion 248 is elastically deformed. Contact the inner surface.

  The cap 300 is detachably attachable to the housing member 100 and has a shape that covers the discharge port 115. As shown in FIG. 2, the cap 300 has a shape that covers the plurality of gap forming portions 122, and is detachably engageable with the outer surface of the fifth wall portion 135.

  Next, how to assemble the extrusion device 1 described above will be described.

  First, the operation unit 230 is attached to the extrusion unit 210. Concretely, the to-be-connected part 240 of the operation part 230 is inserted in the inner cylinder part 216 of the extrusion part 210 (press-fit). As a result, the held portion 242 is held by the holding portion 217, and the opposing portion 244 abuts or faces the receiving portion 218 with a gap. Thus, the extrusion member 200 is assembled.

  Then, the pushing member 200 is inserted into the housing portion 110. Specifically, the pushing portion 210 is inserted (press-fit) into the peripheral wall 112 through the upper opening of the peripheral wall 112. In the present embodiment, since the locking portion 113 has a shape that is recessed outward from the inner circumferential surface of the peripheral wall 112 in the direction orthogonal to the axial direction, locking is performed when the extrusion portion 210 is inserted into the housing portion 110 It is avoided that the part 113 damages the outer peripheral surface of the outer cylinder part 212 of the extrusion part 210. The portion to be locked 248 is elastically deformed in the same direction by receiving an inward external force in the radial direction from the inner circumferential surface of the peripheral wall 112 until the locking portion 113 is reached. When it is reached, the locking portion 113 is engaged by elastic return. Thus, the assembly of the pressing member 200 to the housing member 100 is completed. In the present embodiment, the locked portion 248 is engaged with the locking portion 113 in a state where the assembling of the pressing member 200 to the housing member 100 is completed. Thus, detachment of the pushing member 200 from the housing member 100 is suppressed.

  Further, in a state in which the locked portion 248 is engaged with the locking portion 113 (a state in which the assembling of the pressing member 200 into the housing member 100 is completed), the pushing member 200 is moved from the housing portion 110 to the pushing member 200. Even when the external force in the disengaging direction (upward in FIG. 2) acts to cause the engaged portion 248 to elastically deform so as to increase the radius of curvature, the convex portion 250 abuts on the inner circumferential surface of the peripheral wall 112 By this, further elastic deformation of the locked portion 248 is suppressed. Accordingly, the detachment of the pushing member 200 from the housing portion 110 is suppressed.

  Then, the usage method of the extrusion tool 1 assembled as mentioned above is demonstrated.

  First, the user of the extrusion device 1 removes the cap 300 and brings the contact end 123 of each gap forming portion 122 into contact with the surface S to which the container 10 is to be attached. In the present embodiment, the dimension d1 of each abutting end 123 in the axial orthogonal direction is set to be equal to or larger than the dimension between the third wall 133 and the fourth wall 134 adjacent to each other in the axial orthogonal direction. . Thus, since the length of the contact end 123 in the axial orthogonal direction is secured, in other words, the contact area between the contact end 123 and the attachment surface S is secured. It is suppressed that the contact end 123 slips on the surface S to be attached.

  Then, the user pushes the operation portion 230 along the central axis direction in a state where each contact end 123 is in contact with the attachment surface S. Then, the entire push-out member 200 is displaced toward the discharge port 115 along the central axis direction in a state in which the engaged portion 248 is elastically deformed. At this time, even if an external force that causes the central axis of the push-out member 200 to incline with respect to the central axis direction acts on the push-out member 200, the push-out member 200 pushes against the inner circumferential surface of the peripheral wall 112. And the proximity portions 246, that is, contact at two places separated from each other in the central axis direction, so that the pushing member 200 is pushed toward the discharge port 115 along the central axis direction. It is suppressed that the extrusion member 200 rattles with respect to the accommodating part 110 so that a central axis direction may incline with respect to the central axis direction of the surrounding wall 112. In addition, since the operation unit 230 abuts on the holding unit 242 and the opposing unit 244 with respect to the pushing unit 210, that is, at two places separated from each other in the central axis direction, the central axial direction of the operation unit 230 is the pushing unit It is also suppressed that the operation part 230 rattles with respect to the extrusion part 210 so that it may incline with respect to the central axis direction of 210.

  Furthermore, since the finger holding the pick portion 232 is received by the finger receiving portion 236 at the time of the pushing operation of the pushing member 200, the pushing failure of the pushing member 200 is suppressed.

  Then, when the user pushes the push-out member 200 as it is, the container 10 is discharged onto the adherend surface S. At this time, as shown in FIG. 9, the container 10 discharged from the discharge port 115 has a tip (lower end portion) of each of the wall portions 131 to 135 such that a space is formed between the wall portions 131 to 135. And flows on the surface S to be adhered while contacting with. In other words, the wall portions 131 to 135 restrict the container 10 discharged from the discharge port 115 from adhering to the outer surface (lower surface) of the bottom wall 114. Thus, the area of the container 10 discharged from the discharge port 115 in contact with the container member 100 is reduced, so that the container 10 remaining on the side of the container member 100 when the extrusion device 1 is separated from the attachment surface S. The amount of is reduced.

  Further, the container 10 discharged from the discharge port 115 radially radiates outward beyond the gap forming portion 122 through the gap formed between the gap forming portions 122 along the direction perpendicular to the axis on the attachment surface S. Flow to spread. That is, since a region to which the container 10 is attached is formed outside the gap forming portion 122 in the adherend surface S in the axial orthogonal direction, the enlargement of the extrusion device 1 in the axial orthogonal direction is avoided. However, it is possible to increase the outer shape of the container 10 attached to the adherend surface S and the contact area between the container 10 and the adherend surface S.

  It should be understood that the above-disclosed embodiments disclosed herein are illustrative and non-restrictive in every respect. The scope of the present invention is indicated not by the description of the embodiments described above but by the claims, and further includes all modifications within the meaning and scope equivalent to the claims.

  For example, the peripheral wall 112 and the outer cylinder portion are not limited to the cylindrical shape. The peripheral wall 112 and the outer cylinder portion 212 may be formed in a polygonal cylinder shape.

  Further, the locked portion 248 may be provided on the pushing portion 210 (the upper end portion of the outer cylindrical portion 212, etc.). In that case, the operation unit 230 may be omitted, and the pushing member 200 may be configured only by the pushing unit 210. In this case, the extrusion unit 210 is pressed by a thumb or the like.

  Further, the locking portion 113 is a first notch groove extending from the upper end of the peripheral wall 112 along the central axis direction, and a second notch groove extending from the lower end of the first notch groove along the circumferential direction. And the to-be-locked portion 248 may have a shape movable in each notch groove. In this case, the push-out member 200 is pushed into the peripheral wall 112 along the central axis direction so that the locked portion 248 moves in the first notch groove, and thereafter, the locked portion 248 is the second notch When the push-out member 200 is rotated to move in the groove, the locked portion 248 engages with the locking portion 113 (the assembly of the pressing member 200 to the housing member 100 is completed). Even in this case, detachment of the pushing member 200 from the housing member 100 is suppressed. Further, in this case, when the user uses the extrusion device 1, the operating portion 230 is housed in the housing portion 110 with the locked portion 248 engaged with the locking portion 113 as in the above embodiment. Push into Thereby, the push-out member 200 is pushed into the housing portion 110 while the engaged portion 248 is deformed.

  In addition, each of the wall portions 131 to 135 may have a polygonal cylindrical shape instead of a cylindrical shape. Furthermore, each of the wall portions 131 to 135 may be interrupted at a part in the circumferential direction without being connected in an annular shape.

  Further, as shown in FIG. 10, the operation unit 230 and the extrusion unit 210 may be integrally formed.

  Further, as shown in FIG. 11 and FIG. 12, the extrusion part 210 may have an elastically deformable part 211 which can be elastically deformed in the radial direction instead of the annular protrusion 213. The elastic deformation portion 211 has a shape projecting outward beyond the inner peripheral surface of the peripheral wall 112 in the radial direction when no external force is applied to the elastic deformation portion 211, and the elastic deformation portion 211 performs the radial direction. When an inward external force is applied, it elastically deforms inward in the radial direction. For this reason, when the extrusion part 210 is inserted in the surrounding wall 112, the upper opening of the surrounding wall 112 is sealed.

  Further, as shown in FIG. 13, the housing portion 110 may further include a standing wall 116. The upstanding wall 116 has a shape that stands up from a portion around the discharge port 115 in the inner surface (upper surface) of the bottom wall 114 and is annularly connected around the discharge port 115. Specifically, the inner circumferential surface of the upstanding wall 116, the portion of the bottom wall 114 surrounding the discharge port 115, and the inner circumferential surface of the first wall portion 131 are continuously and smoothly connected. In this aspect, even if water separation occurs from the container 10, the water separation is accumulated in the space defined by the inner peripheral surface of the peripheral wall 112 and the outer peripheral surface of the upstanding wall 116 on the bottom wall 114. That is, in this aspect, the water separation receiving portion that receives water separation by the upper surface of the bottom wall 114, the outer peripheral surface of the rising wall 116, and the portion of the inner peripheral surface of the peripheral wall 112 facing the rising wall 116 in the radial direction. Is formed. Therefore, even if syneresis occurs from the container 10 at the time of storage of the extrusion device 1 or the like, leakage of the syneresis from the discharge port 115 is suppressed.

  Further, when the housing portion 110 has the water separation receiving portion, the pressing wall 214 of the pushing portion 210 pushes the container 10 present inside the water separation receiving portion (outside the upstanding wall 116) toward the discharge port 115. It has an outer pressing portion 220, an inner pressing portion 222 for pushing out the container 10 present in the upstanding wall 116 from the discharge port 115, and a connecting portion 224 connecting the outer pressing portion 220 and the inner pressing portion 222. Is preferred.

  The outer pressing portion 220 has an annularly continuous shape on the outer side of the upstanding wall 116 in the radial direction. The outer pressing portion 220 is connected to the lower end portion of the outer cylindrical portion 212. The lower end surface of the outer pressing portion 220 and the upper surface of the bottom wall 114 are both formed flat.

  The inner pressing portion 222 is located lower than the upper end of the rising wall 116 in a state where the outer pressing portion 220 abuts on the upper surface of the bottom wall 114 (the state shown in FIG. 13). Therefore, the inner pressing portion 222 pushes the container 10 present inside the upstanding wall 116 toward the discharge port 115 when the outer pressing portion 220 is in contact with the upper surface of the bottom wall 114. The lower end surface of the inner pressing portion 222 is formed flat. The lower end surface of the inner pressing portion 222 is disposed above the lower end surface of the outer pressing portion 220. However, the lower end surface of the inner pressing portion 222 may be disposed below the lower end surface of the outer pressing portion 220.

  The connecting portion 224 has a shape for connecting the outer pressing portion 220 and the inner pressing portion 222 while avoiding interference with the rising wall 116 in a state where the outer pressing portion 220 abuts on the upper surface of the bottom wall 114. Specifically, in the state where the outer pressing portion 220 abuts on the upper surface of the bottom wall 114, the connecting portion 224 is a portion of the inner peripheral surface of the inner cylindrical portion 216 above the portion overlapping the rising wall 116 in the radial direction. And protrudes inward in the radial direction, and has a shape connected to the outer end of the inner pressing portion 222.

  In this embodiment, the pushing member 200 is pushed until the outer pressing portion 220 abuts on the upper surface of the bottom wall 114, whereby the inside of the housing 10 and the inside of the standing wall 116 present in the outer side of the standing wall 116 (in the water receiving portion). The container 10 present in the container is discharged from the discharge port 115. Therefore, both suppression of leaked water from the discharge port 115 and reduction of the amount of the container 10 remaining in the container portion 110 are achieved.
