Description

本発明は、収容体を押し出すための押出器具に関する。 The present invention relates to an extruder for extruding an inclusion body.

従来、収容部材に収容された収容体を押出部材によって収容部材から押し出すための押出器具が知られている。例えば、特許文献１には、流動性付着性薬剤（収容体）を収容するシリンダと、シリンダ内に配置されたスライダと、スライダを押圧する押し具と、を備える薬剤用カートリッジ装置（押出器具）が開示されている。 Conventionally, an extruder for extruding an accommodating body accommodated in an accommodating member from the accommodating member by an extruding member is known. For example, Patent Document 1 includes a drug cartridge device (extruder) including a cylinder for accommodating a fluid adhesive agent (accommodating body), a slider arranged in the cylinder, and a pusher for pressing the slider. Is disclosed.

シリンダは、円筒状に形成されており収容体を収容する収容部と、収容部の外周面に接続された末広部と、を有している。収容部の一方側の端部には、収容体を被付着面（便器の内面等）に向けて吐出するための吐出口が形成されている。末広部は、吐出口を包囲する形状を有している。末広部の先端部が被付着面に当接することにより、被付着面と収容部との間に空間が形成される。 The cylinder is formed in a cylindrical shape and has an accommodating portion for accommodating the accommodating body and a divergent portion connected to the outer peripheral surface of the accommodating portion. At one end of the accommodating portion, a discharge port for ejecting the accommodating body toward the adhered surface (inner surface of the toilet bowl, etc.) is formed. The suehiro portion has a shape that surrounds the discharge port. When the tip of the divergent portion abuts on the adhered surface, a space is formed between the adhered surface and the accommodating portion.

スライダは、収容部のうち吐出口とは反対側の開口から収容部内に挿入される。スライダは、収容体を吐出口に向けて押し出すことが可能である。 The slider is inserted into the accommodating portion through the opening of the accommodating portion on the side opposite to the discharge port. The slider can push the containment body toward the discharge port.

押し具は、スライダに接続されており、スライダを収容部の軸方向に沿って吐出口に向けて押し出す。 The pusher is connected to the slider and pushes the slider toward the discharge port along the axial direction of the accommodating portion.

この押出器具の使用時には、末広部の先端部が被付着面に当接した状態で使用者によって押し具が収容部の軸方向に沿って収容部内に向けて押し込まれる。そうすると、スライダが収容部内の収容体を吐出口に向けて押し込むので、収容部と末広部とで区画される空間に吐出口を通じて被付着面に収容体が吐出される。これにより、被付着面のうち末広部に囲まれた部位に収容体が付着する。 When this extruder is used, the pusher is pushed into the accommodating portion along the axial direction of the accommodating portion by the user with the tip end portion of the divergent portion abutting on the surface to be adhered. Then, since the slider pushes the accommodating body in the accommodating portion toward the discharge port, the accommodating body is ejected to the adhered surface through the ejection port in the space partitioned by the accommodating portion and the divergent portion. As a result, the accommodation body adheres to the portion of the adhered surface surrounded by the divergent portion.

特許文献１に記載されるような押出器具では、押出器具の輸送時等における振動が当該押出器具に加わることに起因して、シリンダからスライダ及び押し具が離脱する懸念がある。 In an extruder as described in Patent Document 1, there is a concern that the slider and the pusher may be detached from the cylinder due to vibration applied to the extruder during transportation of the extruder.

そこで、収容部のうち吐出口とは反対側の端部に、抜け止め用の突出部（収容部の径方向について収容部から内向きに突出する形状を有する突起等）を設けることが考えられる。しかしながら、そのような突出部を設けた場合、スライダ、つまり、収容体を吐出口に向けて押し出すことが可能な押出部を収容部内に挿入する際に、その突出部によって押出部の外周面が損傷し、これにより、押出部による収容部の密閉が不十分になるおそれがある。 Therefore, it is conceivable to provide a protrusion for preventing the retaining portion (a protrusion having a shape that protrudes inward from the housing portion in the radial direction of the housing portion, etc.) at the end of the housing portion on the opposite side of the discharge port. .. However, when such a protrusion is provided, when a slider, that is, an extrusion capable of pushing the accommodating body toward the discharge port, is inserted into the accommodating portion, the protrusion causes the outer peripheral surface of the extrusion portion to be raised. It can be damaged, which can result in inadequate sealing of the containment by the extruder.

本発明の目的は、押出部の外周面の損傷を回避しつつ収容部材からの押出部材の離脱を抑制することが可能な押出器具を提供することである。 An object of the present invention is to provide an extruder capable of suppressing the detachment of an extrusion member from an accommodating member while avoiding damage to the outer peripheral surface of the extrusion portion.

前記課題を解決するための手段として、本発明は、収容体を押し出すことが可能な押出器具であって、前記収容体を収容するとともに当該収容体を吐出することが可能な収容部材と、前記収容部材から前記収容体を押し出すための押出部材と、を備え、前記収容部材は、筒状に形成されており前記収容体を収容する収容部を有し、前記収容部は、当該収容部の一端側に形成されており前記収容体を吐出するための吐出口を有し、前記押出部材は、前記収容部の中心軸方向について当該収容部の他端部から前記収容部内に挿入されることが可能で、かつ、前記収容部に収容されている前記収容体が前記吐出口に向けて押し出されるように前記収容部の内周面に接触した状態を維持しながら前記収容部内を前記中心軸方向に沿って変位することが可能な押出部と、前記押出部に接続されており、前記押出部が前記吐出口に向かって変位するように操作者によって操作されることが可能な操作部と、を有し、前記収容部は、前記押出部が当該収容部内に位置する状態において前記押出部材が当該収容部から離脱するのを阻止するように前記押出部材を係止する係止部を有し、前記押出部材は、前記係止部に係合する被係止部と、前記中心軸方向について前記被係止部のうち前記押出部が位置する側とは反対側の部位に設けられた凸部と、を有し、前記係止部は、前記収容部の内周面から前記中心軸方向と直交する方向である軸直交方向ついて外向きに窪む形状を有し、前記被係止部は、当該被係止部に外力が作用していないときに前記軸直交方向について前記収容部の内周面よりも外側に張り出す形状を有するとともに、当該被係止部に前記軸直交方向について内向きの外力が作用したときに前記軸直交方向について内向きに弾性変形する、押出器具を提供する。前記被係止部は、前記軸直交方向について外側に向かうにしたがって次第に前記中心軸方向について前記押出部から離間する方向に向かい、かつ、前記中心軸方向について前記押出部が位置する側に凸となるように湾曲する形状を有している。前記凸部は、前記押出部材に対して当該押出部材が前記収容部から離脱する方向の外力が作用することによって前記被係止部が弾性変形した際に前記収容部の内周面に当接する。 As a means for solving the above-mentioned problems, the present invention comprises an extruder capable of extruding an accommodating body, the accommodating member capable of accommodating the accommodating body and discharging the accommodating body, and the above-mentioned accommodating member. The accommodating member includes an extruding member for extruding the accommodating body from the accommodating member, and the accommodating member is formed in a tubular shape and has an accommodating portion for accommodating the accommodating body. The extruded member is formed on one end side and has a discharge port for discharging the accommodating body, and the extruded member is inserted into the accommodating portion from the other end of the accommodating portion in the direction of the central axis of the accommodating portion. And while maintaining a state of being in contact with the inner peripheral surface of the accommodating portion so that the accommodating body accommodated in the accommodating portion is pushed out toward the discharge port, the inside of the accommodating portion is centered on the central axis. An extruded portion that can be displaced along the direction and an operating portion that is connected to the extruded portion and can be operated by an operator so that the extruded portion is displaced toward the discharge port. The accommodating portion has a locking portion for locking the extruded member so as to prevent the extruded member from detaching from the accommodating portion in a state where the extruded portion is located in the accommodating portion. The extruded member is provided at a locked portion that engages with the locked portion and a portion of the locked portion that is opposite to the side where the extruded portion is located in the central axis direction. The locking portion has a convex portion, and the locking portion has a shape of being recessed outward in an axis orthogonal direction which is a direction orthogonal to the central axis direction from the inner peripheral surface of the accommodating portion, and is locked. The portion has a shape that projects outward from the inner peripheral surface of the accommodating portion in the direction orthogonal to the axis when no external force is applied to the locked portion, and the portion is orthogonal to the axis in the locked portion. Provided is an extruder that elastically deforms inward in the direction orthogonal to the axis when an inward external force is applied to the extruder. The locked portion gradually moves outward in the direction orthogonal to the axis toward the direction away from the extruded portion in the central axis direction, and is convex toward the side where the extruded portion is located in the central axis direction. It has a shape that curves so as to become. The convex portion abuts on the inner peripheral surface of the accommodating portion when the locked portion is elastically deformed due to an external force acting on the extruded member in a direction in which the extruded member separates from the accommodating portion. ..

本押出器具では、係止部が収容部の内周面から前記軸直交方向について外向きに窪む形状を有しているので、押出部の収容部内への挿入時に係止部が押出部の外周面を損傷させることが回避される。さらに、押出部の収容部内への挿入時、被係止部は、係止部に至るまでの間は収容部の内周面から前記軸直交方向について内向きの外力を受けることによって同向きに弾性変形しており、係止部に至ったときに弾性復帰することによって係止部に係合する。よって、押出器具の輸送時等における振動に起因して押出部材が収容部材から離脱することが抑制される。 In this extruder, the locking portion has a shape that is recessed outward from the inner peripheral surface of the accommodating portion in the direction orthogonal to the axis. Damage to the outer peripheral surface is avoided. Further, when the extruded portion is inserted into the accommodating portion, the locked portion receives an inward external force from the inner peripheral surface of the accommodating portion in the direction orthogonal to the axis until the locked portion reaches the locked portion. It is elastically deformed and engages with the locking portion by elastically returning when it reaches the locking portion. Therefore, it is possible to prevent the extruder member from detaching from the accommodating member due to vibration during transportation of the extruder.

また、押出部材が吐出口へ向かって変位する際に被係止部が弾性変形しやすくなり、かつ、被係止部が係止部に係合した状態から押出部材を収容部から離脱させる方向の外力が当該押出部材に作用したときに被係止部が弾性変形しにくくなる。よって、押出部の収容部内への挿入や、被係止部が係止部に係合した状態から操作部を押圧する操作が容易になり、かつ、押出部材の収容部からの離脱が有効に規制される。 Further , when the extruded member is displaced toward the discharge port, the locked portion is likely to be elastically deformed, and the extruded member is disengaged from the accommodating portion from the state where the locked portion is engaged with the locked portion. When the external force of the above acts on the extruded member, the locked portion is less likely to be elastically deformed. Therefore, it is easy to insert the extruded portion into the accommodating portion and to press the operation portion from the state where the locked portion is engaged with the locking portion, and it is effective to release the extruded member from the accommodating portion. Be regulated.

また、押出部材に対して当該押出部材が収容部から離脱する方向の外力が作用することによって被係止部がその曲率半径を大きくするように弾性変形した場合に、凸部が収容部の内周面に当接するので、被係止部のそれ以上の弾性変形が抑制される。よって、押出部材の収容部からの離脱がより確実に抑制される。 Further , when the locked portion is elastically deformed so as to increase the radius of curvature of the locked portion due to an external force acting on the extruded member in the direction in which the extruded member is separated from the accommodating portion, the convex portion is inside the accommodating portion. Since it comes into contact with the peripheral surface, further elastic deformation of the locked portion is suppressed. Therefore, the extruded member is more reliably suppressed from being separated from the accommodating portion.

以上のように、本発明によれば、押出部の外周面の損傷を回避しつつ収容部材からの押出部材の離脱を抑制することが可能な押出器具を提供することができる。 As described above, according to the present invention, it is possible to provide an extruder capable of suppressing the detachment of the extrusion member from the accommodating member while avoiding damage to the outer peripheral surface of the extrusion portion.

The peripheral wall 112 locks the extruded member 200 so as to prevent the extruded member 200 from detaching from the peripheral wall 112 when a part of the extruded member 200 (extruded portion 210 described later) is located in the peripheral wall 112. It has a locking portion 113. As shown in FIGS. 2 and 7, the locking portion 113 has a shape of being recessed outward from the inner peripheral surface of the peripheral wall 112 in the radial direction of the peripheral wall 112.

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

付着抑制部１３０は、底壁１１４の外面に収容体１０が付着するのを抑制する。図３及び図４に示されるように、付着抑制部１３０は、底壁１１４の外面のうち吐出口１１５の周囲の部位に接続された複数の壁部１３１～１３５を有する。本実施形態では、複数の壁部１３１～１３５は、第１壁部１３１と、第２壁部１３２と、第３壁部１３３と、第４壁部１３４と、第５壁部１３５と、を有している。各壁部１３１～１３５は、底壁１１４の外面から下向きに延びる形状を有している。本実施形態では、各壁部１３１～１３５は、吐出口１１５の周囲において円環状につながる形状を有している。第１壁部１３１は、当該第１壁部１３１の内周面が底壁１１４のうち吐出口１１５を取り囲む部位とつながる位置に配置されている。各壁部１３１～１３５は、前記軸直交方向（底壁１１４の径方向）に互いに離間した位置に配置されている。例えば、各壁部間の寸法は、２ｍｍ程度に設定される。 The adhesion suppressing portion 130 suppresses the attachment of the housing 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 separated from each other in the direction orthogonal to the axis (diametrical direction of the bottom wall 114). For example, the dimension between each wall portion is set to about 2 mm.

図３に示されるように、前記中心軸方向についての第１壁部１３１の寸法よりも同方向についての第２壁部１３２の寸法の方が大きい。同様に、前記中心軸方向についての第２壁部１３２の寸法よりも同方向についての第３壁部１３３の寸法の方が大きい。前記中心軸方向についての第４壁部１３４の寸法及び第５壁部１３５の寸法は、同方向についての第３壁部１３３の寸法と同じである。本実施形態では、第１壁部１３１の前記寸法は１ｍｍに設定されており、第２壁部１３２の前記寸法は３ｍｍに設定されており、第３壁部１３３～第５壁部１３５の前記寸法は５ｍｍに設定されている。 As shown in FIG. 3, the dimension of the second wall portion 132 in the same direction is larger than the dimension of the first wall portion 131 in the central axis direction. Similarly, the dimension of the third wall portion 133 in the same direction is larger than the dimension of the second wall portion 132 in the central axis direction. The dimensions of the fourth wall portion 134 and the dimensions of the fifth wall portion 135 in the central axis direction are the same as the dimensions of the third wall portion 133 in the same direction.

The dimension of the extension portion 238 in the central axis direction is set so that the grip portion 232 is exposed from the accommodating portion 110 in a state where the pressing wall 214 is in contact with the bottom wall 114.

被接続部２４０は、内筒部２１６に接続される部位である。図５、図７及び図８に示されるように、被接続部２４０は、被保持部２４２と、対向部２４４と、を有する。被保持部２４２は、内筒部２１６の保持部２１７に保持される部位である。被保持部２４２は、円板状に形成されている。保持部２１７は、この被保持部２４２を前記中心軸方向の両側から挟持する。この保持部２１７による被保持部２４２の挟持力の方が押出部２１０と周壁１１２の内周面との間に生じる摩擦力よりも大きくなるように、保持部２１７の形状と環状突起２１３の外筒部２１２の外周面から突出量とが設定されている。このため、前記中心軸方向に沿って操作部２３０が押出部２１０から離間する向きの外力が当該操作部２３０に作用した場合における操作部２３０の押出部２１０からの離脱が抑制される。対向部２４４は、前記中心軸方向について被保持部２４２から離間した位置に設けられている。本実施形態では、対向部２４４は、被保持部２４２の上方に設けられている。対向部２４４は、円板状に形成されている。対向部２４４の径方向についての当該対向部２４４の外端部は、内筒部２１６の内周面に当接、あるいは、前記内周面と所定の隙間（例えば０．１ｍｍ程度）を置いて対向している。つまり、内筒部２１６のうち対向部２４４の外端部と当接するあるいは前記外端部と所定の隙間を置いて対向する部位が、前記中心軸方向について保持部２１７から離間した位置で操作部２３０を受ける「受け部２１８」に相当する。 The connected portion 240 is a portion connected to the inner cylinder portion 216. As shown in FIGS. 5, 7 and 8, the connected portion 240 has a held portion 242 and a facing portion 244. The held portion 242 is a portion held by the holding portion 217 of the inner cylinder portion 216. The held portion 242 is formed in a disk shape. The holding portion 217 sandwiches the held portion 242 from both sides in the central axial direction. The shape of the holding portion 217 and the outside of the annular protrusion 213 so that the holding force of the held portion 242 by the holding portion 217 is larger than the frictional force generated between the extruded portion 210 and the inner peripheral surface of the peripheral wall 112. The amount of protrusion from the outer peripheral surface of the tubular portion 212 is set. Therefore, when an external force in a direction in which the operation unit 230 is separated from the extrusion unit 210 along the central axis direction acts on the operation unit 230, the operation unit 230 is suppressed from being separated from the extrusion unit 210. The facing portion 244 is provided at a position separated from the held portion 242 in the central axial 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 peripheral surface of the inner cylinder portion 216, or a predetermined gap (for example, about 0.1 mm) is provided between the inner peripheral surface and the inner peripheral surface. Facing each other. That is, the operation unit is located at a position where the portion of the inner cylinder portion 216 that abuts on the outer end portion of the facing portion 244 or faces the outer end portion with a predetermined gap is separated from the holding portion 217 in the central axial direction. Corresponds to the "receiver 218" that receives 230.

近接部２４６は、押出部２１０が吐出口１１５に向かって変位する間に周壁１１２の内周面に当接し続ける（摺接する）あるいは前記内周面と所定の隙間（例えば０．１ｍｍ程度）を置いて対向し続ける部位である。近接部２４６は、延長部２３８から前記軸直交方向（指受け部２３６が摘み本体２３３から突出する方向と同じ方向）に張り出す形状を有している。図５及び図８に示されるように、本実施形態では、近接部２４６は、前記軸直交方向について延長部２３８から一方側に張り出す第１張出部２４６ａと、他方側に張り出す第２張出部２４６ｂと、を有する。前記軸直交方向についての各張出部２４６ａ，２４６ｂの外端部は、周壁１１２の内周面に沿う形状に形成されている。各張出部２４６ａ，２４６ｂは、平板状に形成されている。 The proximity portion 246 continues to abut (sliding) with the inner peripheral surface of the peripheral wall 112 while the extruded 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 keeps facing each other. The proximity portion 246 has a shape that projects from the extension portion 238 in the direction orthogonal to the axis (the same direction as the direction in which the finger receiving portion 236 protrudes from the picking body 233). As shown in FIGS. 5 and 8, in the present embodiment, the proximity portion 246 has a first overhanging portion 246a projecting from the extension portion 238 to one side and a second projecting portion 246a extending to the other side in the direction orthogonal to the axis.

被係止部２４８は、周壁１１２の係止部１１３に係合する部位である。被係止部２４８は、延長部２３８から前記軸直交方向に突出する形状を有している。本実施形態では、被係止部２４８は、第１張出部２４６ａと第２張出部２４６ｂとを結ぶ方向と直交する方向について延長部２３８から一方側に突出する第１腕部２４８ａと、他方側に突出する第２腕部２４８ｂと、を有する。図７に示されるように、各腕部２４８ａ，２４８ｂは、当該腕部２４８ａ，２４８ｂに外力が作用していないときに前記軸直交方向（前記径方向）について周壁１１２の内周面よりも外側に張り出す形状を有する。なお、図７は、被係止部２４８が係止部１１３に係合した状態を示している。また、各腕部２４８ａ，２４８ｂは、当該腕部２４８ａ，２４８ｂに前記軸直交方向について内向きの外力が作用したときに前記軸直交方向について内向きに弾性変形する。本実施形態では、各腕部２４８ａ，２４８ｂは、前記軸直交方向について外側に向かうにしたがって次第に上方（前記中心軸方向について摘み部２３２に近付く方向）に向かい、かつ、下側（前記中心軸方向について被接続部２４０が位置する側）に凸となるように湾曲する形状を有する。 The locked portion 248 is a portion that engages with the locking portion 113 of the peripheral wall 112. The locked portion 248 has a shape protruding from the extension portion 238 in the direction orthogonal to the axis. In the present embodiment, the locked portion 248 includes a first arm portion 248a projecting unilaterally from the extension portion 238 in a direction orthogonal to the direction connecting the first overhanging portion 246a and the second overhanging portion 246b. It has a second arm portion 248b protruding to the other side. As shown in FIG. 7, each arm portion 248a, 248b is outside the inner peripheral surface of the peripheral wall 112 in the axial orthogonal direction (the radial direction) when no external force is applied to the arm portions 248a, 248b. It has a shape that overhangs. Note that FIG. 7 shows a state in which the locked portion 248 is engaged with the locking portion 113. Further, the arm portions 248a and 248b are elastically deformed inward in the axial orthogonal direction when an inward external force is applied to the arm portions 248a and 248b in the axial orthogonal direction. In the present embodiment, the arm portions 248a and 248b gradually move upward (direction approaching the knob portion 232 in the central axis direction) and downward (the central axis direction) toward the outside in the direction orthogonal to the axis. It has a shape that curves so as to be convex toward the side on which the connected portion 240 is located.

凸部２５０は、被係止部２４８の各腕部２４８ａ，２４８ｂの上面に設けられている。凸部２５０は、押出部材２００に対して当該押出部材２００が収容部１１０から離脱する方向（図２における上向き）の外力が作用することによって被係止部２４８が弾性変形した際に周壁１１２の内周面に当接する。 The convex portion 250 is provided on the upper surface of each arm portion 248a, 248b of the locked portion 248. The convex portion 250 has a peripheral wall 112 when the locked portion 248 is elastically deformed by an external force acting on the extruded member 200 in the direction in which the extruded member 200 is separated from the accommodating portion 110 (upward in FIG. 2). It abuts on the inner peripheral surface.

As shown in FIG. 2, the cap 300 has a shape that covers the plurality of gap forming portions 122, and can be detachably engaged with the outer surface of the fifth wall portion 135.

次に、以上に説明した押出器具１の組立て方について説明する。 Next, a method of assembling the extruder 1 described above will be described.

まず、押出部２１０に操作部２３０が装着される。具体的に、押出部２１０の内筒部２１６に操作部２３０の被接続部２４０が挿入（圧入）される。これにより、被保持部２４２が保持部２１７に保持され、対向部２４４が受け部２１８に当接あるいは隙間を置いて対向する。このようにして押出部材２００が組立てられる。 First, the operation unit 230 is attached to the extrusion unit 210. Specifically, the connected portion 240 of the operation portion 230 is inserted (press-fitted) into the inner cylinder portion 216 of the extrusion portion 210. As a result, the held portion 242 is held by the holding portion 217, and the facing portion 244 abuts or faces the receiving portion 218 with a gap. The extrusion member 200 is assembled in this way.

そして、その押出部材２００が収容部１１０内に挿入される。具体的に、周壁１１２の上側の開口を通じて周壁１１２内に押出部２１０が挿入（圧入）される。本実施形態では、係止部１１３は、周壁１１２の内周面から前記軸直交方向について外向きに窪む形状を有しているので、押出部２１０の収容部１１０内への挿入時に係止部１１３が押出部２１０の外筒部２１２の外周面を損傷させることが回避される。そして、被係止部２４８は、係止部１１３に至るまでの間は周壁１１２の内周面から前記径方向について内向きの外力を受けることによって同向きに弾性変形し、係止部１１３に至ったときに弾性復帰することによって係止部１１３に係合する。これにより、押圧部材２００の収容部材１００への組み付けが完了する。本実施形態では、押圧部材２００の収容部材１００への組み付けが完了した状態において、被係止部２４８が係止部１１３に係合しているので、押出器具１の輸送時等における振動に起因して押出部材２００が収容部材１００から離脱することが抑制される。 Then, the extruded member 200 is inserted into the accommodating portion 110. Specifically, the extruded portion 210 is inserted (press-fitted) into the peripheral wall 112 through the opening on the upper side of the peripheral wall 112. In the present embodiment, since the locking portion 113 has a shape of being recessed outward from the inner peripheral surface of the peripheral wall 112 in the direction orthogonal to the axis, the locking portion 113 is locked when the extruded portion 210 is inserted into the accommodating portion 110. It is avoided that the portion 113 damages the outer peripheral surface of the outer cylinder portion 212 of the extrusion portion 210. Then, the locked portion 248 elastically deforms in the same direction by receiving an inward external force in the radial direction from the inner peripheral surface of the peripheral wall 112 until it reaches the locking portion 113, and becomes the locking portion 113. When it reaches the limit, it elastically returns to engage with the locking portion 113. This completes the assembly of the pressing member 200 to the accommodating member 100. In the present embodiment, in the state where the pressing member 200 is assembled to the accommodating member 100, the locked portion 248 is engaged with the locking portion 113, which is caused by vibration during transportation of the extruder 1. As a result, the extrusion member 200 is prevented from being separated from the accommodating member 100.

また、被係止部２４８が係止部１１３に係合した状態（押圧部材２００の収容部材１００への組み付けが完了した状態）において、押出部材２００に対して当該押出部材２００が収容部１１０から離脱する方向（図２の上向き）の外力が作用することによって被係止部２４８がその曲率半径を大きくするように弾性変形したとしても、凸部２５０が周壁１１２の内周面に当接することによって被係止部２４８のそれ以上の弾性変形が抑制される。よって、押出部材２００の収容部１１０からの離脱が抑制される。 Further, in a state where the locked portion 248 is engaged with the locking portion 113 (a state in which the pressing member 200 is assembled to the accommodating member 100), the extruded member 200 is attached to the extruded member 200 from the accommodating portion 110. Even if the locked portion 248 is elastically deformed so as to increase its radius of curvature due to the action of an external force in the direction of disengagement (upward in FIG. 2), the convex portion 250 abuts on the inner peripheral surface of the peripheral wall 112. Further elastic deformation of the locked portion 248 is suppressed. Therefore, the extruded member 200 is suppressed from being detached from the accommodating portion 110.

続いて、以上のようにして組立てられた押出器具１の使用方法について説明する。 Subsequently, a method of using the extruder 1 assembled as described above will be described.

まず、押出器具１の使用者は、キャップ３００を取り外し、収容体１０を付着させたい被付着面Ｓに各隙間形成部１２２の当接端部１２３を当接させる。本実施形態では、各当接端部１２３の前記軸直交方向についての寸法ｄ１は、前記軸直交方向に互いに隣接する第３壁部１３３及び第４壁部１３４間の寸法以上に設定されている。このように、前記軸直交方向についての当接端部１２３の長さが確保されているので、換言すれば、当接端部１２３と被付着面Ｓとの接触面積が確保されているので、当接端部１２３が被付着面Ｓに対して滑ることが抑制される。 First, the user of the extruder 1 removes the cap 300 and brings the contact end portion 123 of each gap forming portion 122 into contact with the adhered surface S to which the accommodating body 10 is to be adhered. In the present embodiment, the dimension d1 of each contact end portion 123 in the direction orthogonal to the axis is set to be equal to or larger than the dimension between the third wall portion 133 and the fourth wall portion 134 adjacent to each other in the orthogonal direction to the axis. .. In this way, since the length of the contact end portion 123 in the direction orthogonal to the axis is secured, in other words, the contact area between the contact end portion 123 and the adhered surface S is secured. The contact end portion 123 is prevented from slipping with respect to the adhered surface S.

そして、使用者は、各当接端部１２３が被付着面Ｓに当接している状態において操作部２３０を前記中心軸方向に沿って押し込む。そうすると、被係止部２４８が弾性変形した状態で押出部材２００全体が前記中心軸方向に沿って吐出口１１５に向かって変位する。このとき、押出部材２００の中心軸を前記中心軸方向に対して傾かせるような外力が当該押出部材２００に作用したとしても、押出部材２００は、周壁１１２の内周面に対し、押出部２１０及び近接部２４６、つまり、前記中心軸方向に互いに離間した２か所で当接するので、前記中心軸方向に沿って押出部材２００が吐出口１１５に向けて押込操作される間、押出部材２００の中心軸方向が周壁１１２の中心軸方向に対して傾斜するように押出部材２００が収容部１１０に対してがたつくことが抑制される。また、操作部２３０は、押出部２１０に対し、被保持部２４２及び対向部２４４、つまり、前記中心軸方向に互いに離間した２か所で当接するので、操作部２３０の中心軸方向が押出部２１０の中心軸方向に対して傾斜するように操作部２３０が押出部２１０に対してがたつくことも抑制される。 Then, the user pushes the operation unit 230 along the central axis direction in a state where each contact end portion 123 is in contact with the adhered surface S. Then, the entire extruded member 200 is displaced toward the discharge port 115 along the central axis direction in a state where the locked portion 248 is elastically deformed. At this time, even if an external force that tilts the central axis of the extruded member 200 with respect to the central axis direction acts on the extruded member 200, the extruded member 200 has the extruded portion 210 with respect to the inner peripheral surface of the peripheral wall 112. And the proximity portion 246, that is, the extruded member 200 abuts at two locations separated from each other in the central axial direction, so that the extruded member 200 is pushed toward the discharge port 115 along the central axial direction. The extrusion member 200 is prevented from rattling with respect to the accommodating portion 110 so that the central axial direction is inclined with respect to the central axial direction of the peripheral wall 112. Further, since the operation unit 230 abuts on the extrusion unit 210 at the held portion 242 and the facing portion 244, that is, at two locations separated from each other in the central axis direction, the central axis direction of the operation unit 230 is the extrusion unit. It is also possible to prevent the operation unit 230 from rattling with respect to the extrusion unit 210 so as to be inclined with respect to the central axis direction of the 210.

さらに、押出部材２００の押込操作時に摘み部２３２を摘まんでいる指が指受け部２３６で受けられるので、押出部材２００の押込み損ねが抑制される。 Further, since the finger holding the grip portion 232 is received by the finger receiving portion 236 during the pushing operation of the extrusion member 200, the pushing failure of the extrusion member 200 is suppressed.

そして、使用者が押出部材２００をそのまま押し込むと、収容体１０が被付着面Ｓに吐出される。このとき、図９に示されるように、吐出口１１５から吐出された収容体１０は、各壁部１３１～１３５間に空間が形成されるように各壁部１３１～１３５の先端部（下端部）に接触しながら被付着面Ｓ上を広がるように流動する。換言すれば、各壁部１３１～１３５は、吐出口１１５から吐出された収容体１０が底壁１１４の外面（下面）に付着するのを規制する。よって、吐出口１１５から吐出された収容体１０が収容部材１００に接触する面積が低減されるので、当該押出器具１を被付着面Ｓから離間させた際に収容部材１００側に残る収容体１０の量が低減される。 Then, when the user pushes the extruded member 200 as it is, the accommodating body 10 is discharged to the adhered surface S. At this time, as shown in FIG. 9, the accommodating body 10 discharged from the discharge port 115 has a tip portion (lower end portion) of each wall portion 131 to 135 so that a space is formed between the wall portions 131 to 135. ), It flows so as to spread on the adhered surface S. In other words, each wall portion 131 to 135 regulates that the accommodating body 10 discharged from the discharge port 115 adheres to the outer surface (lower surface) of the bottom wall 114. Therefore, since the area where the accommodating body 10 discharged from the discharge port 115 comes into contact with the accommodating member 100 is reduced, the accommodating body 10 remaining on the accommodating member 100 side when the extruder 1 is separated from the adhered surface S. The amount of is reduced.

また、吐出口１１５から吐出された収容体１０は、被付着面Ｓ上を前記軸直交方向に沿って隙間形成部１２２間に形成される隙間を通じて隙間形成部１２２よりも外側に向かって放射状に広がるように流動する。すなわち、前記軸直交方向について被付着面Ｓのうち隙間形成部１２２よりも外側に収容体１０が付着する領域が形成されるので、当該押出器具１の前記軸直交方向への大型化を回避しながら、被付着面Ｓに付着した収容体１０の外形や当該収容体１０と被付着面Ｓとの接触面積を大きくすることが可能となる。 Further, the accommodating body 10 discharged from the discharge port 115 radiates outward from the gap forming portion 122 through the gap formed between the gap forming portions 122 along the axis orthogonal direction on the adhered surface S. It flows to spread. That is, since the region to which the accommodating body 10 adheres is formed outside the gap forming portion 122 of the adhered surface S in the direction orthogonal to the axis, it is possible to avoid increasing the size of the extruder 1 in the direction orthogonal to the axis. However, it is possible to increase the outer shape of the housing 10 attached to the adhered surface S and the contact area between the housing 10 and the adhered surface S.

なお、今回開示された上記実施形態は、すべての点で例示であって制限的なものではないと考えられるべきである。本発明の範囲は、上記した実施形態の説明ではなく特許請求の範囲によって示され、さらに特許請求の範囲と均等の意味および範囲内でのすべての変更が含まれる。 It should be noted that the above-described embodiment disclosed this time is exemplary in all respects and is not considered to be restrictive. The scope of the present invention is shown by the scope of claims rather than the description of the embodiment described above, and further includes all modifications within the meaning and scope equivalent to the scope of claims.

例えば、周壁１１２及び外筒部は、円筒状に限られない。これら周壁１１２及び外筒部２１２は、多角筒状に形成されてもよい。 For example, the peripheral wall 112 and the outer cylinder portion are not limited to a cylindrical shape. The peripheral wall 112 and the outer cylinder portion 212 may be formed in a polygonal cylinder shape.

また、被係止部２４８は、押出部２１０（外筒部２１２の上端部等）に設けられていてもよい。その場合、操作部２３０が省略され、押出部材２００が押出部２１０のみで構成されてもよい。この場合、押出部２１０は、親指等で押圧される。 Further, the locked portion 248 may be provided on the extruded portion 210 (the upper end portion of the outer cylinder portion 212 or the like). In that case, the operation unit 230 may be omitted, and the extrusion member 200 may be composed of only the extrusion unit 210. In this case, the extruded portion 210 is pressed by a thumb or the like.

また、係止部１１３は、周壁１１２の上端部から前記中心軸方向に沿って延びる第１切欠き溝と、第１切欠き溝の下端部から前記周方向に沿って延びる第２切欠き溝と、を有し、被係止部２４８は、各切欠き溝内を移動可能な形状を有していてもよい。この場合、被係止部２４８が第１切欠き溝内を移動するように前記中心軸方向に沿って押出部材２００が周壁１１２内に押し込まれ、その後、被係止部２４８が第２切欠き溝内を移動するように押出部材２００が回転されることによって被係止部２４８が係止部１１３と係合する（押圧部材２００の収容部材１００への組み付けが完了する）。このようにしても、押出部材２００が収容部材１００から離脱することが抑制される。また、この場合において、使用者がこの押出器具１を使用する際は、上記実施形態と同様、被係止部２４８が係止部１１３に係合した状態のまま操作部２３０を収容部１１０内に押し込む。これにより、被係止部２４８が変形しながら押出部材２００が収容部１１０内に押し込まれる。 Further, the locking portion 113 includes a first notch groove extending along the central axis direction from the upper end portion of the peripheral wall 112 and a second notch groove extending along the circumferential direction from the lower end portion of the first notch groove. And, the locked portion 248 may have a shape that can move in each notch groove. In this case, the extruded member 200 is pushed into the peripheral wall 112 along the central axial direction so that the locked portion 248 moves in the first notch groove, and then the locked portion 248 is notched in the second notch. By rotating the extrusion member 200 so as to move in the groove, the locked portion 248 engages with the locking portion 113 (the assembly of the pressing member 200 to the accommodating member 100 is completed). Even in this way, it is possible to prevent the extruded member 200 from being separated from the accommodating member 100. Further, in this case, when the user uses the extruder 1, the operating portion 230 is housed in the accommodating portion 110 with the locked portion 248 engaged with the locking portion 113, as in the above embodiment. Push into. As a result, the extruded member 200 is pushed into the accommodating portion 110 while the locked portion 248 is deformed.

また、各壁部１３１～１３５は、円筒状でなく多角筒状でもよい。さらに、各壁部１３１～１３５は、環状につながることなく周方向の一部で途切れていてもよい。 Further, each wall portion 131 to 135 may have a polygonal tubular shape instead of a cylindrical shape. Further, each wall portion 131 to 135 may be interrupted at a part in the circumferential direction without being connected to an annular shape.

また、図１０に示されるように、操作部２３０と押出部２１０とが一体的に形成されてもよい。 Further, as shown in FIG. 10, the operation unit 230 and the extrusion unit 210 may be integrally formed.

また、図１１及び図１２に示されるように、押出部２１０は、環状突起２１３の代わりに、前記径方向に弾性変形可能な弾性変形部２１１を有していてもよい。弾性変形部２１１は、当該弾性変形部２１１に外力が作用していないときに前記径方向について周壁１１２の内周面よりも外側に張り出す形状を有するとともに、当該弾性変形部２１１に前記径方向について内向きの外力が作用したときに前記径方向について内向きに弾性変形する。このため、押出部２１０が周壁１１２内に挿入されることにより、周壁１１２の上側の開口が密閉される。 Further, as shown in FIGS. 11 and 12, the extruded portion 210 may have an elastically deformable portion 211 elastically deformable in the radial direction instead of the annular projection 213. The elastically deformed portion 211 has a shape that projects outward from the inner peripheral surface of the peripheral wall 112 in the radial direction when no external force is applied to the elastically deformed portion 211, and the elastically deformed portion 211 has the radial direction. When an inward external force is applied to the material, it elastically deforms inward in the radial direction. Therefore, by inserting the extruded portion 210 into the peripheral wall 112, the opening on the upper side of the peripheral wall 112 is sealed.

また、図１３に示されるように、収容部１１０は、起立壁１１６をさらに有していてもよい。起立壁１１６は、底壁１１４の内面（上面）うち吐出口１１５の周囲の部位から起立するとともに吐出口１１５の周囲において環状につながる形状を有する。具体的に、起立壁１１６の内周面、底壁１１４のうち吐出口１１５を取り囲む部位及び第１壁部１３１の内周面は、連続的に滑らかにつながっている。この態様では、収容体１０から離水が生じたとしても、その離水は、底壁１１４上のうち周壁１１２の内周面と起立壁１１６の外周面とで区画される空間に溜まる。つまり、この態様では、底壁１１４の上面と、起立壁１１６の外周面と、周壁１１２の内周面のうち起立壁１１６と前記径方向に対向する部位と、により、離水を受ける離水受け部が形成される。よって、押出器具１の保管時等に収容体１０から離水が生じたとしても、その離水が吐出口１１５から漏出することが抑制される。 Further, as shown in FIG. 13, the accommodating portion 110 may further have an upright wall 116. The upright wall 116 has a shape that stands up from a portion of the inner surface (upper surface) of the bottom wall 114 around the discharge port 115 and is connected in an annular shape around the discharge port 115. Specifically, the inner peripheral surface of the upright wall 116, the portion of the bottom wall 114 that surrounds the discharge port 115, and the inner peripheral surface of the first wall portion 131 are continuously and smoothly connected. In this aspect, even if water is separated from the housing 10, the water separation is accumulated in the space on the bottom wall 114 which is divided by the inner peripheral surface of the peripheral wall 112 and the outer peripheral surface of the upright wall 116. 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 upright wall 116, and the portion of the inner peripheral surface of the peripheral wall 112 that faces the upright wall 116 in the radial direction. Is formed. Therefore, even if water is separated from the accommodating body 10 during storage of the extruder 1, the water separation is suppressed from leaking from the discharge port 115.

また、収容部１１０が前記離水受け部を有する場合、押出部２１０の押圧壁２１４は、前記離水受け部内（起立壁１１６の外側）に存在する収容体１０を吐出口１１５に向けて押し出すための外側押圧部２２０と、起立壁１１６内に存在する収容体１０を吐出口１１５から押し出すための内側押圧部２２２と、外側押圧部２２０と内側押圧部２２２とを連結する連結部２２４と、を有することが好ましい。 Further, when the accommodating portion 110 has the water separation receiving portion, the pressing wall 214 of the extrusion portion 210 pushes the accommodating body 10 existing in the water separation receiving portion (outside of the standing wall 116) toward the discharge port 115. It has an outer pressing portion 220, an inner pressing portion 222 for pushing out the accommodating body 10 existing in the upright wall 116 from the discharge port 115, and a connecting portion 224 for connecting the outer pressing portion 220 and the inner pressing portion 222. Is preferable.

外側押圧部２２０は、前記径方向について起立壁１１６の外側において環状につながる形状を有する。外側押圧部２２０は、外筒部２１２の下端部に接続されている。外側押圧部２２０の下端面及び底壁１１４の上面は、ともに平坦に形成されている。 The outer pressing portion 220 has a shape connected in an annular shape on the outside of the upright wall 116 in the radial direction. The outer pressing portion 220 is connected to the lower end portion of the outer cylinder portion 212. Both the lower end surface of the outer pressing portion 220 and the upper surface of the bottom wall 114 are formed flat.

内側押圧部２２２は、外側押圧部２２０が底壁１１４の上面に当接した状態（図１３に示される状態）において、起立壁１１６の上端部よりも下側に位置する。このため、内側押圧部２２２は、外側押圧部２２０が底壁１１４の上面に当接した状態のときに起立壁１１６の内側に存在する収容体１０を吐出口１１５に向けて押し出す。内側押圧部２２２の下端面は、平坦に形成されている。この内側押圧部２２２の下端面は、外側押圧部２２０の下端面よりも上方に配置されている。ただし、内側押圧部２２２の下端面は、外側押圧部２２０の下端面よりも下方に配置されてもよい。 The inner pressing portion 222 is located below the upper end portion of the upright wall 116 in a state where the outer pressing portion 220 is in contact with the upper surface of the bottom wall 114 (the state shown in FIG. 13). Therefore, the inner pressing portion 222 pushes out the housing 10 existing inside the standing 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 arranged above the lower end surface of the outer pressing portion 220. However, the lower end surface of the inner pressing portion 222 may be arranged below the lower end surface of the outer pressing portion 220.

連結部２２４は、外側押圧部２２０が底壁１１４の上面に当接した状態において、起立壁１１６と干渉するのを回避しながら外側押圧部２２０と内側押圧部２２２とを連結する形状を有する。具体的に、連結部２２４は、外側押圧部２２０が底壁１１４の上面に当接した状態において内筒部２１６の内周面のうち前記径方向について起立壁１１６と重なる部位よりも上側の部位から前記径方向の内向きに張り出すとともに、内側押圧部２２２の外端部につながる形状を有する。 The connecting portion 224 has a shape that connects the outer pressing portion 220 and the inner pressing portion 222 while avoiding interference with the upright wall 116 in a state where the outer pressing portion 220 is in contact with the upper surface of the bottom wall 114. Specifically, the connecting portion 224 is a portion of the inner peripheral surface of the inner cylinder portion 216 above the portion overlapping the upright wall 116 in the radial direction in a state where the outer pressing portion 220 is in contact with the upper surface of the bottom wall 114. It has a shape that projects inward in the radial direction from the above and is connected to the outer end portion of the inner pressing portion 222.

この態様では、外側押圧部２２０が底壁１１４の上面に当接するまで押出部材２００が押し込まれることにより、起立壁１１６の外側（前記離水受け部内）に存在する収容体１０及び起立壁１１６の内側に存在する収容体１０が吐出口１１５から吐出される。よって、離水が吐出口１１５から漏出するのを抑制することと、収容部１１０内に残る収容体１０の量を低減することと、の双方が達成される。 In this embodiment, the extrusion member 200 is pushed until the outer pressing portion 220 abuts on the upper surface of the bottom wall 114, so that the inside of the housing 10 and the upright wall 116 existing on the outside of the upright wall 116 (inside the water separation receiving portion). The accommodating body 10 existing in the above is discharged from the discharge port 115. Therefore, both suppressing the leakage of water from the discharge port 115 and reducing the amount of the accommodating body 10 remaining in the accommodating portion 110 are achieved.
