しかしながら、前記従来の吐出器では、前記カバー体が吐出器本体から外れ易く、しかも外された後に再度装着されると、カバー体が外れたことがあるか否かの判別が困難であり、前述の要望に対応し難いという問題があった。   However, in the conventional discharger, it is difficult to determine whether or not the cover body has been removed when the cover body is easily detached from the main body of the discharger and is attached again after being removed. There was a problem that it was difficult to respond to the request.

この発明は、このような事情を考慮してなされたもので、販売前の流通、保管時あるいは販売陳列時等に、他人により意図的にあるいは不意に外力が加えられてもカバー体が吐出器本体から外れるのを防ぐことができるとともに、カバー体が吐出器本体から外されたことがあるか否かを容易に判別することが可能で、さらに購入者自身が内容物の使用を開始した後も、不意に加えられた外力により内容物が吐出されてしまうのを防ぐことができる吐出器を提供することを目的とする。   The present invention has been made in consideration of such circumstances, and the cover body is a discharge device even if an external force is intentionally or unexpectedly applied by another person during distribution, storage, or sales display before sales. It is possible to prevent the cover body from being detached from the main body, and it is possible to easily determine whether or not the cover body has been removed from the main body of the dispenser. Another object of the present invention is to provide a discharger that can prevent the contents from being discharged due to an external force applied unexpectedly.

上記課題を解決して、このような目的を達成するために、本発明の吐出器は、内容物が収容された容器体の口部に装着される有頂筒状の装着キャップと、この装着キャップに上方付勢状態で下方移動可能に貫設されたステムを有するポンプと、前記ステムの上端に装着されるとともに吐出孔が形成された押下ヘッドと、を備え、前記押下ヘッドを押下して前記ステムを下方に移動させ前記ポンプを作動させることにより、容器体内の内容物が移送されて前記吐出孔から吐出される吐出器本体を有する吐出器であって、前記吐出器本体のうち前記装着キャップの天壁部よりも上方に位置する部分を覆うカバー体を備え、このカバー体は、前記吐出器本体において前記装着キャップの天壁部と前記押下ヘッドとの間に位置し、かつ前記押下ヘッドの外径よりも小径の中間部分に離脱可能に外嵌されるとともに、下端が前記装着キャップの天壁部上に配置された下筒部と、この下筒部と一体に形成されるとともに前記押下ヘッドを覆う上筒部と、を備え、前記下筒部は、上下方向における全長にわたって延びる開口部を有し上面視C字状に形成され、前記カバー体および吐出器本体の径方向に沿った相対的な進退移動に伴い、前記中間部分が前記開口部を径方向に通過することで前記下筒部内に対して嵌合および離脱され、前記上筒部は、前記押下ヘッドを径方向の外側から覆う周壁部を備え、この周壁部は、それぞれが上面視C字状に形成された第1周壁体および第2周壁体を備え、これらの第1周壁体および第2周壁体それぞれにおける両周端部のうちの一方の周端部同士がヒンジ部により連結されて該ヒンジ部回りに回転自在に構成されるとともに、他方の周端部同士が破断可能な連結部材により連結され、前記第1周壁体の下端部が前記下筒部の上端部に接続され、前記押下ヘッドは、頂壁部とこの頂壁部から下方に向けて延設された筒体とを備え、前記下筒部の上端は、前記筒体の下端に下側から近接若しくは当接していることを特徴とする。 In order to solve the above-mentioned problems and achieve such an object, a discharger according to the present invention includes a top cylindrical mounting cap mounted on the mouth of a container body containing the contents, and this mounting A pump having a stem penetrating the cap so as to be movable downward in an upwardly biased state, and a pressing head mounted on the upper end of the stem and having a discharge hole formed therein, and pressing the pressing head A discharger having a discharger main body in which the contents in the container are transferred and discharged from the discharge hole by moving the stem downward and operating the pump, wherein the mounting is included in the discharger main body. A cover body covering a portion located above the top wall portion of the cap; the cover body is located between the top wall portion of the mounting cap and the pressing head in the main body of the discharger; head The outer cylinder is detachably fitted to an intermediate part having a smaller diameter than the outer diameter, and the lower cylinder part is disposed on the top wall part of the mounting cap, and the lower cylinder part is formed integrally with the lower cylinder part and the press An upper cylindrical portion covering the head, and the lower cylindrical portion has an opening extending over the entire length in the vertical direction and is formed in a C-shape when viewed from above, along the radial direction of the cover body and the discharger body Along with the relative advance and retreat movement, the intermediate portion is fitted and detached from the inside of the lower cylinder portion by passing through the opening portion in the radial direction, and the upper cylinder portion moves the pressing head outward in the radial direction. The peripheral wall portion includes a first peripheral wall body and a second peripheral wall body, each of which is formed in a C shape in a top view, and both the circumferences of the first peripheral wall body and the second peripheral wall body, respectively. One of the end parts is the hinge part The other peripheral end portions are connected by a breakable connecting member, and the lower end portion of the first peripheral wall body is connected to the upper end portion of the lower cylinder portion. And the pressing head includes a top wall portion and a cylindrical body extending downward from the top wall portion, and an upper end of the lower cylindrical portion is adjacent to a lower end of the cylindrical body from below or It is characterized by abutting .

この発明によれば、上筒部の連結部材が破断される前には、上筒部の周壁部が押下ヘッドを径方向の外側から覆っているので、カバー体の吐出器本体に対する径方向の移動が規制され、また、下筒部内に押下ヘッドの外径より小径の前記中間部分が嵌合されているので、下筒部の上端が押下ヘッドの下端に当接することで、カバー体の吐出器本体に対する上方に向けた移動も規制されることとなる。したがって、販売前の流通、保管時あるいは販売陳列時等に、他人により意図的にあるいは不意に外力が加えられてもカバー体が吐出器本体から外れるのを防ぐことができる。   According to this invention, before the connecting member of the upper cylinder part is broken, the peripheral wall part of the upper cylinder part covers the pressing head from the outside in the radial direction. Since the movement is restricted and the intermediate portion having a diameter smaller than the outer diameter of the pressing head is fitted in the lower cylinder portion, the upper end of the lower cylinder portion comes into contact with the lower end of the pressing head, thereby discharging the cover body. The upward movement with respect to the main body is also restricted. Therefore, it is possible to prevent the cover body from being detached from the main body of the dispenser even if an external force is intentionally or unexpectedly applied by another person during distribution, storage or sales display before sales.

また、カバー体を吐出器本体から外すには、第1周壁体および第2周壁体を、それぞれの他方の周端部同士が互いに離間する方向に前記ヒンジ部回りに回転させて前記連結部材を破断させ、その後、カバー体および吐出器本体を相対的に径方向に沿って離間移動させることで、吐出器本体の前記中間部分を下筒部の開口部を径方向に通過させて下筒部内から離脱させる。
このように、カバー体を吐出器本体から外すためには、上筒部の連結部材を破断しなければならず、連結部材を破断した後は、第2周壁体が第1周壁体に対して不安定で初期姿勢に復元不能となり、購入者にカバー体が吐出器本体から外されたことがあるか否かを容易に判別させることができる。
Further, in order to remove the cover body from the discharger main body, the first peripheral wall body and the second peripheral wall body are rotated around the hinge portion in a direction in which the other peripheral end portions are separated from each other. Then, the cover body and the discharger body are moved relatively apart from each other in the radial direction so that the intermediate part of the discharger body passes through the opening of the lower cylinder part in the radial direction, and the inside of the lower cylinder part To leave.
Thus, in order to remove the cover body from the main body of the discharger, the connecting member of the upper tube portion must be broken, and after the breaking of the connecting member, the second peripheral wall body is against the first peripheral wall body. It is unstable and cannot be restored to the initial posture, and the purchaser can easily determine whether or not the cover body has been removed from the dispenser body.

そして、購入者において内容物の使用後に保管する際には、下筒部の開口部と、吐出器本体の前記中間部分と、を径方向で互いに対向させた状態で、カバー体と吐出器本体とを相対的に径方向に接近移動させることにより、吐出器本体の前記中間部分を下筒部の開口部を径方向に通過させて下筒部内に嵌合させ、カバー体を吐出器本体に装着する。これにより、押下ヘッドは、径方向の外側から上筒部の第1周壁体により覆われ、また下筒部の下端は、装着キャップの天壁部上に配置され、さらに下筒部の上端と押下ヘッドの下端とが上下方向で対向若しくは当接する。   When the purchaser stores the contents after use, the cover body and the discharger main body with the opening of the lower cylinder part and the intermediate part of the discharger main body facing each other in the radial direction. Is moved relatively close in the radial direction, the intermediate portion of the discharger body is passed through the opening of the lower cylinder part in the radial direction and fitted into the lower cylinder part, and the cover body is attached to the discharger body. Installing. Thereby, the pressing head is covered with the first peripheral wall body of the upper cylindrical portion from the outside in the radial direction, and the lower end of the lower cylindrical portion is disposed on the top wall portion of the mounting cap, and further, the upper end of the lower cylindrical portion is The lower end of the pressing head faces or abuts in the vertical direction.

以上のように、販売前の流通、保管時あるいは販売陳列時、さらには購入者による内容物の使用後の保管時の別を問わず、カバー体を吐出器本体に装着した状態では、下筒部の下端が装着キャップの天壁部上に配置されるとともに、下筒部の上端と押下ヘッドの下端とが上下方向で対向若しくは当接しているので、吐出器に押下ヘッドおよびステムを下方に移動させる外力が加えられても、その力が、下筒部を介して装着キャップに伝達されて容器体により受け止められることとなり、押下ヘッドおよびステムの下方への移動を防止することができる。
したがって、販売前の流通、保管時あるいは販売陳列時、さらには購入者による内容物の使用後の保管時の別を問わず、カバー体が吐出器本体に装着されているときには、他人により意図的にあるいは不意に加えられた外力によって内容物が吐出されてしまうのを防ぐことができる。
さらに、下筒部の上端が、押下ヘッドの筒体の下端に下側から近接若しくは当接しているので、販売前の流通、保管時あるいは販売陳列時、さらには購入者による内容物の使用後の保管時の別を問わず、カバー体が吐出器本体に装着されているときには、他人により意図的にあるいは不意に加えられた外力によって、押下ヘッドが押し下げられるのをより一層確実に防ぐことができる。
As described above, when the cover body is attached to the main body of the dispenser, regardless of whether it is in distribution before storage, storage or sales display, or storage after the purchaser uses the contents, the lower cylinder The lower end of the part is disposed on the top wall of the mounting cap, and the upper end of the lower cylinder part and the lower end of the pressing head are opposed to or in contact with each other in the vertical direction. Even when an external force to be moved is applied, the force is transmitted to the mounting cap via the lower cylinder portion and is received by the container body, and the downward movement of the pressing head and the stem can be prevented.
Therefore, when the cover body is attached to the main body of the dispenser, whether it is distributed before storage, at the time of storage or at the time of display, or at the time of storage after use of the contents by the purchaser, it is intentional by others. It is possible to prevent the contents from being discharged due to an external force applied to the user.
Furthermore, since the upper end of the lower cylinder part is close to or in contact with the lower end of the cylinder of the pressing head from the lower side, during distribution before storage, storage or sales display, and after use of the contents by the purchaser Regardless of the storage time, when the cover body is attached to the main body of the dispenser, it is possible to more reliably prevent the pressing head from being pushed down by an external force applied intentionally or unexpectedly by another person. it can.

ここで、前記押下ヘッドの外周面には、先端に前記吐出孔が形成された吐出筒が径方向の外側に向けて突設され、前記上筒部の第1周壁体における周方向の中央部には、内部に前記吐出筒が収納される先端閉塞の収納体が径方向の外側に向けて突設されてもよい。   Here, on the outer peripheral surface of the pressing head, a discharge cylinder having the discharge hole formed at the tip thereof protrudes outward in the radial direction, and a central portion in the circumferential direction of the first peripheral wall body of the upper cylinder portion Alternatively, a container with a closed end, in which the discharge cylinder is accommodated, may be provided so as to protrude outward in the radial direction.

この場合、収納体が、上筒部の第1周壁体における周方向の中央部に径方向の外側に向けて突設されているので、内容物の使用後に、カバー体を再度吐出器本体に装着するために、下筒部の開口部と、吐出器本体の前記中間部分と、を径方向で互いに対向させたときに、吐出筒の先端と収納体の内部とを径方向で互いに対向させることも可能になる。これにより、カバー体と吐出器本体とを相対的に径方向に接近移動させたときに、吐出筒を収納体の内部に進入させながら、下筒部内に吐出器本体の前記中間部分を嵌合することが可能になり、カバー体を吐出器本体に容易に装着することができる。   In this case, since the storage body protrudes radially outward at the central portion in the circumferential direction of the first peripheral wall body of the upper cylindrical portion, the cover body is again attached to the discharger body after use of the contents. For mounting, when the opening of the lower cylinder and the intermediate portion of the discharger body are opposed to each other in the radial direction, the tip of the discharge cylinder and the inside of the storage body are opposed to each other in the radial direction. It becomes possible. As a result, when the cover body and the discharger body are moved relatively close to each other in the radial direction, the intermediate part of the discharger body is fitted into the lower tube part while the discharge tube is inserted into the housing body. The cover body can be easily attached to the discharger body.

また、前記第2周壁体の内周面における曲率半径は、前記押下ヘッドの外周面における曲率半径よりも大きくなってもよい。   The radius of curvature of the inner peripheral surface of the second peripheral wall body may be larger than the radius of curvature of the outer peripheral surface of the pressing head.

この場合、第2周壁体の内周面における曲率半径が、押下ヘッドの外周面における曲率半径よりも大きくなっているので、連結部材を破断した後は、第2周壁体を押下ヘッドに外嵌させて固定することができなくなる。したがって、第2周壁体が第1周壁体のみならず押下ヘッドに対しても不安定となり、第2周壁体の初期姿勢を確実に復元不能にすることが可能になり、購入者にカバー体が吐出器本体から外されたことがあるか否かをより一層容易に判別させることができる。   In this case, since the curvature radius on the inner peripheral surface of the second peripheral wall body is larger than the curvature radius on the outer peripheral surface of the pressing head, the second peripheral wall body is externally fitted to the pressing head after the connecting member is broken. Can not be fixed. Therefore, the second peripheral wall body becomes unstable not only with respect to the first peripheral wall body but also with respect to the pressing head, and the initial posture of the second peripheral wall body can be surely made unrecoverable. It can be determined even more easily whether or not it has been removed from the discharger body.

この発明によれば、販売前の流通、保管時あるいは販売陳列時等に、他人により意図的にあるいは不意に外力が加えられてもカバー体が吐出器本体から外れるのを防ぐことができるとともに、カバー体が吐出器本体から外されたことがあるか否かを容易に判別することが可能で、さらに購入者自身が内容物の使用を開始した後も、不意に加えられた外力により内容物が吐出されてしまうのを防ぐことができる。   According to the present invention, it is possible to prevent the cover body from being detached from the main body of the dispenser even when external force is intentionally or unexpectedly applied by another person during distribution, storage or sales display before sales, etc. It is possible to easily determine whether or not the cover body has been removed from the main body of the dispenser, and even after the purchaser has started using the contents, the contents are unexpectedly applied by the external force. Can be prevented from being discharged.

In the illustrated example, the upper end portion of the guide tube portion 22 is always located in the surrounding tube portion 28 regardless of whether the press head 14 is pressed or not pressed.

以上の構成において、押下ヘッド14を押下すると、まずステム12が下方に向けて移動させられる。このステム12の移動に追従して、前記ピストン部材がシリンダ23の内周面に摺接しつつ下方に移動する。これにより、シリンダ23内の内容物が圧縮され、この圧縮されたシリンダ23内の内容物が、ステム12内に進入してこのステム12内を上方に向けて移動する。
その後、押下ヘッド14の押下を解除すると、前記ピストン部材が前記付勢部材の上方付勢力によりシリンダ23の内周面に摺接しつつ上方に向けて復元移動する。これにより、シリンダ23内が減圧され、容器体2内に収容されている内容物がパイプ25を通してシリンダ23内に吸い上げられる。
In the above configuration, when the pressing head 14 is pressed, the stem 12 is first moved downward. Following the movement of the stem 12, the piston member moves downward while being in sliding contact with the inner peripheral surface of the cylinder 23. As a result, the contents in the cylinder 23 are compressed, and the compressed contents in the cylinder 23 enter the stem 12 and move upward in the stem 12.
Thereafter, when the pressing of the pressing head 14 is released, the piston member is restored and moved upward while being in sliding contact with the inner peripheral surface of the cylinder 23 by the upward biasing force of the biasing member. As a result, the inside of the cylinder 23 is depressurized, and the contents stored in the container body 2 are sucked into the cylinder 23 through the pipe 25.

そして本実施形態では、カバー体18は、図1から図6に示されるように、吐出器本体16において装着キャップ11の天壁部17と押下ヘッド14との間に位置する装着キャップ11の案内筒部22に離脱可能に外嵌された下筒部30と、この下筒部30と一体に形成されるとともに押下ヘッド14を覆う上筒部31と、を備えている。   In the present embodiment, as shown in FIGS. 1 to 6, the cover body 18 guides the mounting cap 11 located between the top wall portion 17 of the mounting cap 11 and the pressing head 14 in the discharger body 16.

As shown in FIG. 5, the through-hole 34 f includes a small-diameter portion 34 d located on the front surface side in contact with the second plate-like body 35 a in the first plate-like body 34 a and a large diameter located on the back surface side opposite to the front surface. And a diameter portion 34e. In the present embodiment, the connecting member is a protrusion 37 projecting from the surface of the second plate 35a that contacts the first plate 34a. The protrusion 37 includes a breakable connecting portion 37a connected to the surface of the second plate-like body 35a, and a locking portion 37b provided at the tip of the connecting portion 37a. The outer diameter of the locking portion 37b is gradually reduced from the proximal end side on the connection portion 37a side toward the distal end side, and the outer diameter at the proximal end portion is larger than the outer diameter of the connection portion 37a. .

これにより、図5に示す状態から、第1周壁体34および第2周壁体35を、それぞれの他方の周端部同士を接近させるようにヒンジ部36回りに回転させると、突起体37の係止部37bが、貫通孔34fの小径部34dの内周面に摺接しつつ、この小径部34dを通過して大径部34eに進入する。この際、図4に示されるように、第1板状体34aおよび第2板状体35aの各表面が互いに重ね合わされ、かつ突起体37の係止部37bにおける基端側の端面37cが、大径部34eの内面に引っ掛かる。なお、突起体37の接続部37aは、貫通孔34fの小径部34d内に位置している。   Accordingly, when the first peripheral wall body 34 and the second peripheral wall body 35 are rotated around the hinge portion 36 so as to bring the other peripheral end portions closer to each other from the state shown in FIG. The stop portion 37b passes through the small diameter portion 34d and enters the large diameter portion 34e while being in sliding contact with the inner peripheral surface of the small diameter portion 34d of the through hole 34f. At this time, as shown in FIG. 4, the surfaces of the first plate 34 a and the second plate 35 a are overlapped with each other, and the end surface 37 c on the proximal end side of the locking portion 37 b of the protrusion 37 is It catches on the inner surface of the large diameter portion 34e. The connecting portion 37a of the protrusion 37 is located in the small diameter portion 34d of the through hole 34f.

そして、第1周壁体34および第2周壁体35を、それぞれの他方の周端部同士を離間させるようにヒンジ部36回りに回転させると、突起体37の係止部37bにおける基端側の端面37cが貫通孔34fの大径部34eの内面に引っ掛かることで、突起体37の接続部37aが破断させられる。   And if the 1st surrounding wall body 34 and the 2nd surrounding wall body 35 are rotated around the hinge part 36 so that each other surrounding edge part may space apart, the base end side in the latching | locking part 37b of the protrusion 37 will be demonstrated. When the end surface 37c is hooked on the inner surface of the large diameter portion 34e of the through hole 34f, the connection portion 37a of the protrusion 37 is broken.

ここで、第1周壁体34の下端部は、その周方向における中央部と下筒部30の周方向における中央部とが互いに一致させられた状態で、下筒部30の上端部に接続されている。これにより、第1周壁体34および下筒部30と、第2周壁体35と、がヒンジ部36回りに相対的に回転自在になっている。

Here, the lower end portion of the first peripheral wall body 34 is connected to the upper end portion of the lower cylindrical portion 30 in a state where the central portion in the circumferential direction and the central portion in the circumferential direction of the lower cylindrical portion 30 are aligned with each other. ing. Thereby, the 1st surrounding wall body 34 and the lower cylinder part 30, and the 2nd surrounding wall body 35 are relatively rotatable around the hinge part 36. As shown in FIG.
Further, in the present embodiment, at the center portion in the circumferential direction of the first peripheral wall body 34, a storage body 38 with a closed end, in which the discharge cylinder 29 of the pressing head 14 is stored, protrudes outward in the radial direction. ing. A gap is provided between the inner surface of the storage body 38 and the outer surface of the discharge cylinder 29.

さらに本実施形態では、第1周壁体34は、押下ヘッド14の囲繞筒部28における上部28aを覆う大径部34bと、囲繞筒部28の下部28bを覆う小径部34cと、を備えている。第2周壁体35の上端縁は、頂部32よりも下方に離れていて、この第2周壁体35は、押下ヘッド14の囲繞筒部28のうち下部28bのみを覆い、上部28aは露出させている。また、囲繞筒部28の上部28aの外周面は、下方から上方に向かうに従い漸次、第1周壁体34の小径部34cにおける上端縁、および第2周壁体35の上端開口縁から径方向の外側に張り出している。さらに、第2周壁体35は、第1周壁体34の小径部34cよりも上下方向の大きさが短くなっており、この第2周壁体35の下端縁は、第1周壁体34の下端縁よりも上方に位置している。
また本実施形態では、第2周壁体35の内周面における曲率半径は、押下ヘッド14の囲繞筒部28における下部28bの外周面における曲率半径よりも大きくなっている。
Furthermore, in the present embodiment, the first peripheral wall body 34 includes a large-diameter portion 34b that covers the upper portion 28a of the surrounding tube portion 28 of the pressing head 14 and a small-diameter portion 34c that covers the lower portion 28b of the surrounding tube portion 28. . The upper end edge of the second peripheral wall body 35 is separated below the top portion 32. The second peripheral wall body 35 covers only the lower portion 28b of the surrounding cylinder portion 28 of the pressing head 14, and the upper portion 28a is exposed. Yes. Further, the outer peripheral surface of the upper part 28a of the surrounding cylinder part 28 gradually increases from the lower side to the upper side in the radial direction from the upper end edge of the small diameter part 34c of the first peripheral wall body 34 and the upper end opening edge of the second peripheral wall body 35. Overhangs. Further, the second peripheral wall 35 is shorter in the vertical direction than the small diameter portion 34 c of the first peripheral wall 34, and the lower end edge of the second peripheral wall 35 is the lower end edge of the first peripheral wall 34. It is located above.
In the present embodiment, the radius of curvature of the inner peripheral surface of the second peripheral wall 35 is larger than the radius of curvature of the outer peripheral surface of the lower portion 28 b of the surrounding cylinder portion 28 of the pressing head 14.

以上の構成において、カバー体18を吐出器本体18から外すには、まず、第1周壁体34および第2周壁体35を、それぞれの他方の周端部同士が互いに離間する方向にヒンジ部36回りに回転させて突起体37の接続部37aを破断させる。そして、カバー体18および吐出器本体16を相対的に径方向に沿って離間移動させることで、装着キャップ11の案内筒部22を下筒部30の開口部30aを径方向に通過させて下筒部30内から離脱させる。   In the above configuration, in order to remove the cover body 18 from the discharger main body 18, first, the first peripheral wall body 34 and the second peripheral wall body 35 are hinged in the direction in which the other peripheral end portions are separated from each other. The connecting portion 37a of the protrusion 37 is broken by rotating around. Then, by moving the cover body 18 and the discharger main body 16 relatively away from each other along the radial direction, the guide cylinder portion 22 of the mounting cap 11 is passed through the opening 30a of the lower cylinder portion 30 in the radial direction. It is made to detach | leave from the cylinder part 30 inside.

そして、購入者において内容物の使用後に保管する際には、下筒部30の開口部30aと、装着キャップ11の案内筒部22と、を径方向で互いに対向させた状態で、カバー体18と吐出器本体16とを相対的に径方向に接近移動させることにより、案内筒部22を下筒部30の開口部30aを径方向に通過させて下筒部30内に嵌合させ、カバー体18を吐出器本体16に装着する。これにより、押下ヘッド14は、上方から上筒部31の頂部32により覆われるとともに、径方向の外側から上筒部31の第1周壁体34により覆われ、また下筒部30の下端は、装着キャップ11の天壁部17上に配置され、さらに下筒部30の上端と押下ヘッド14の囲繞筒部28の下端開口縁とが上下方向で対向若しくは当接する。   When the purchaser stores the contents after use, the cover body 18 in a state where the opening 30a of the lower cylinder part 30 and the guide cylinder part 22 of the mounting cap 11 face each other in the radial direction. And the discharger body 16 are moved relatively close to each other in the radial direction so that the guide tube portion 22 is fitted in the lower tube portion 30 by passing through the opening 30a of the lower tube portion 30 in the radial direction. The body 18 is attached to the dispenser body 16. Thereby, the pressing head 14 is covered by the top portion 32 of the upper cylindrical portion 31 from above, and is covered by the first peripheral wall body 34 of the upper cylindrical portion 31 from the outside in the radial direction, and the lower end of the lower cylindrical portion 30 is It is arranged on the top wall portion 17 of the mounting cap 11, and the upper end of the lower cylinder portion 30 and the lower end opening edge of the surrounding cylinder portion 28 of the pressing head 14 are opposed or abutted in the vertical direction.

以上説明したように、本実施形態による吐出器1によれば、カバー体18の上筒部31の突起体37が破断される前には、上筒部31の周壁部33が押下ヘッド14を径方向の外側から覆っているので、カバー体18の吐出器本体16に対する径方向の移動が規制され、また、下筒部30内に装着キャップ11の案内筒部22が嵌合されているので、下筒部30の上端が押下ヘッド14の囲繞筒部28の下端開口縁に当接することで、カバー体18の吐出器本体16に対する上方に向けた移動も規制されることとなる。   As described above, according to the dispenser 1 according to the present embodiment, the peripheral wall portion 33 of the upper cylindrical portion 31 causes the pressing head 14 to move before the projection 37 of the upper cylindrical portion 31 of the cover body 18 is broken. Since the cover body 18 is covered from the outside in the radial direction, the movement of the cover body 18 in the radial direction with respect to the discharger body 16 is restricted, and the guide cylinder portion 22 of the mounting cap 11 is fitted in the lower cylinder portion 30. Since the upper end of the lower cylinder part 30 abuts on the lower end opening edge of the surrounding cylinder part 28 of the pressing head 14, the upward movement of the cover body 18 relative to the discharger body 16 is also restricted.

したがって、販売前の流通、保管時あるいは販売陳列時等に、他人により意図的にあるいは不意に外力が加えられてもカバー体18が吐出器本体16から外れるのを防ぐことができる。
また、カバー体18を吐出器本体16から外すためには、上筒部31の突起体37を破断しなければならず、突起体37を破断した後は、第2周壁体35が第1周壁体34に対して不安定で初期姿勢に復元不能となり、購入者にカバー体18が吐出器本体16から外されたことがあるか否かを容易に判別させることができる。
Therefore, it is possible to prevent the cover body 18 from being detached from the discharger main body 16 even if an external force is intentionally or unexpectedly applied by another person during distribution, storage or sales display before sales.
Further, in order to remove the cover body 18 from the discharger main body 16, the protrusion 37 of the upper cylinder portion 31 must be broken, and after the protrusion 37 is broken, the second peripheral wall 35 becomes the first peripheral wall. It is unstable with respect to the body 34 and cannot be restored to the initial posture, and the purchaser can easily determine whether or not the cover body 18 has been removed from the discharger body 16.

さらに、販売前の流通、保管時あるいは販売陳列時、さらには購入者による内容物の使用後の保管時の別を問わず、カバー体18を吐出器本体16に装着した状態では、下筒部30の下端が装着キャップ11の天壁部17上に配置されるとともに、下筒部30の上端と押下ヘッド14の囲繞筒部28の下端開口縁とが上下方向で対向若しくは当接しているので、吐出器1に押下ヘッド14およびステム12を下方に移動させる外力が加えられても、その力が、下筒部30を介して装着キャップ11に伝達されて容器体2により受け止められることとなり、押下ヘッド14およびステム12の下方への移動を防止することができる。
したがって、販売前の流通、保管時あるいは販売陳列時、さらには購入者による内容物の使用後の保管時の別を問わず、カバー体18が吐出器本体16に装着されているときには、他人により意図的にあるいは不意に加えられた外力によって内容物が吐出されてしまうのを防ぐことができる。
さらに本実施形態では、押下ヘッド14が、上方からも上筒部31の頂部32により覆われているので、内容物の予期しない吐出を確実に防ぐことができる。
Further, in the state where the cover body 18 is mounted on the discharger main body 16 regardless of whether it is in distribution before storage, storage or sales display, or storage after use of the contents by the purchaser, the lower cylinder portion Since the lower end of 30 is disposed on the top wall portion 17 of the mounting cap 11, the upper end of the lower cylinder portion 30 and the lower end opening edge of the surrounding cylinder portion 28 of the pressing head 14 are opposed or abutted in the vertical direction. Even if an external force that moves the pressing head 14 and the stem 12 downward is applied to the ejector 1, the force is transmitted to the mounting cap 11 via the lower cylindrical portion 30 and is received by the container body 2, The downward movement of the pressing head 14 and the stem 12 can be prevented.
Therefore, when the cover body 18 is attached to the discharger main body 16 regardless of whether it is distributed before storage, during storage or at the time of sales display, or even after storage by the purchaser, the cover body 18 is attached by the other person. The contents can be prevented from being discharged by an external force applied intentionally or unexpectedly.
Furthermore, in this embodiment, since the pressing head 14 is covered with the top part 32 of the upper cylinder part 31 also from the upper part, the unexpected discharge of the content can be prevented reliably.

また本実施形態では、収納体38が、上筒部31の第1周壁体34における周方向の中央部に径方向の外側に向けて突設されているので、内容物の使用後に、カバー体18を再度吐出器本体16に装着するために、下筒部30の開口部30aと、装着キャップ11の案内筒部22と、を径方向で互いに対向させたときに、吐出筒29の先端と収納体38の内部とを径方向で互いに対向させることも可能になる。これにより、カバー体18と吐出器本体16とを相対的に径方向に接近移動させたときに、吐出筒29を収納体38の内部に進入させながら、下筒部30内に案内筒部22を嵌合することが可能になり、カバー体18を吐出器本体16に容易に装着することができる。   Moreover, in this embodiment, since the storage body 38 is projected toward the outer side in the radial direction at the central portion in the circumferential direction of the first peripheral wall body 34 of the upper cylindrical portion 31, the cover body is used after the contents are used. When the opening portion 30a of the lower tube portion 30 and the guide tube portion 22 of the mounting cap 11 are opposed to each other in the radial direction in order to mount the 18 to the discharger body 16 again, the tip of the discharge tube 29 It is also possible to make the inside of the storage body 38 face each other in the radial direction. As a result, when the cover body 18 and the discharger main body 16 are moved relatively close to each other in the radial direction, the guide tube portion 22 is inserted into the lower tube portion 30 while the discharge tube 29 enters the inside of the storage body 38. So that the cover body 18 can be easily attached to the discharger body 16.

さらに本実施形態では、第2周壁体35の内周面における曲率半径が、押下ヘッド14の囲繞筒部28における下部28bの外周面における曲率半径よりも大きくなっているので、突起体37を破断した後は、第2周壁体35を押下ヘッド14の囲繞筒部28における下部28bに外嵌させて固定することができなくなる。したがって、第2周壁体35が第1周壁体34のみならず押下ヘッド14に対しても不安定となり、第2周壁体35の初期姿勢を確実に復元不能にすることが可能になり、購入者にカバー体18が吐出器本体16から外されたことがあるか否かをより一層容易に判別させることができる。   Furthermore, in this embodiment, since the radius of curvature of the inner peripheral surface of the second peripheral wall 35 is larger than the radius of curvature of the outer peripheral surface of the lower portion 28b of the surrounding cylinder portion 28 of the pressing head 14, the protrusion 37 is broken. After that, the second peripheral wall body 35 cannot be fitted and fixed to the lower portion 28b of the surrounding cylinder portion 28 of the pressing head 14. Accordingly, the second peripheral wall body 35 becomes unstable not only with respect to the first peripheral wall body 34 but also with the pressing head 14, and the initial posture of the second peripheral wall body 35 can be reliably made unrecoverable. Thus, it can be more easily determined whether or not the cover body 18 has been removed from the discharger body 16.

また本実施形態では、下筒部30の上端が、押下ヘッド14の囲繞筒部28の下端開口縁に下側から近接若しくは当接しているので、販売前の流通、保管時あるいは販売陳列時、さらには購入者による内容物の使用後の保管時の別を問わず、カバー体18が吐出器本体16に装着されているときには、他人により意図的にあるいは不意に加えられた外力によって、押下ヘッド14が押し下げられるのをより一層確実に防ぐことができる。   Further, in the present embodiment, the upper end of the lower cylinder part 30 is close to or abuts the lower end opening edge of the surrounding cylinder part 28 of the pressing head 14 from the lower side, so that it can be distributed, stored or sold before sales. Furthermore, when the cover body 18 is attached to the discharger main body 16, regardless of whether the purchaser stores the contents after use, the pressing head is caused by an external force intentionally or unexpectedly applied by another person. It can prevent still more reliably that 14 is pushed down.

さらに本実施形態では、第1周壁体34が、囲繞筒部28の上部28aを覆う大径部34bと、囲繞筒部28の下部28bを覆う小径部34cと、を備え、囲繞筒部28の上部28aの外周面が、下方から上方に向かうに従い漸次、第1周壁体34の小径部34cにおける上端縁から径方向の外側に張り出しているので、カバー体18および吐出器本体16を相対的に径方向に接近移動させて、カバー体18を吐出器本体16に装着する際に、囲繞筒部28の上部28aの外周面を、第1周壁体34における小径部34cの上端部により下側から支持させることが可能になり、両者18、16の上下方向に沿った相対的な位置がずれるのを抑制することができる。   Furthermore, in the present embodiment, the first peripheral wall body 34 includes a large-diameter portion 34b that covers the upper portion 28a of the surrounding tube portion 28 and a small-diameter portion 34c that covers the lower portion 28b of the surrounding tube portion 28. Since the outer peripheral surface of the upper portion 28a gradually protrudes outward in the radial direction from the upper end edge of the small diameter portion 34c of the first peripheral wall body 34 as it goes from the lower side to the upper side, the cover body 18 and the discharger body 16 are relatively moved. When the cover body 18 is attached to the discharger main body 16 by moving close to the radial direction, the outer peripheral surface of the upper portion 28a of the surrounding cylinder portion 28 is moved from the lower side by the upper end portion of the small diameter portion 34c of the first peripheral wall body 34. It becomes possible to support, and it can suppress that the relative position along the up-down direction of both 18 and 16 shifts | deviates.
