本開示は、レフィル容器に関する。 The present disclosure relates to a refill container.

従来、クリーム状等の内容物のレフィル（付け替え）等の目的で用いられる内容器と、内容器を収容する外容器とを有するレフィル容器が知られている。このようなレフィル容器は、内容器を外容器に着脱可能とするための構成を有している。例えば特許文献１では、レフィル容器は、外容器に回動可能に取り付けられる肩カバーを有しており、当該肩カバーを外容器に対して回動させることによって内容器を外容器から取り外せるように構成されている。 Conventionally, a refill container having an inner container used for the purpose of refilling (replacement) contents such as cream and an outer container for accommodating the inner container is known. Such a refill container has a configuration for making the inner container removable from the outer container. For example, in Patent Document 1, the refill container has a shoulder cover that is rotatably attached to the outer container, and the inner container can be removed from the outer container by rotating the shoulder cover with respect to the outer container. It is configured.

本実施形態に係るレフィル容器１は、例えば以下の要領によって、内容器２を外容器３から取り外すことができる。蓋４を取り外した状態で、使用者は、内容器２を外容器３から取り外すために、まず、内容器２のフランジ６の外縁を下方に押圧する。このとき、使用者が、図７に示すように、フランジ６の外縁における上凸部９側部分（すなわち、周方向において上凸部９が形成されている部分）を押圧した場合には、内周壁５の中心軸線を挟んだ当該押圧部の対向部分には嵌合凸部１０がないため、当該対向部分における内周壁５の下部が外周壁１１に近づくように内容器２が傾かせられて、嵌合部１５と５個の嵌合凸部１０との嵌合が解け、前記対向部分におけるフランジ６が浮き上がり、この浮き上がったフランジ６と外周壁１１の上端面１６との間の隙間が拡大する。したがって、図８に示すように、内容器２を容易に摘み上げることができる。一方、使用者が、図９に示すように、フランジ６の外縁における非上凸部９側部分（すなわち、周方向において上凸部９が形成されていない部分）を押圧した場合には、当該押圧部には上凸部９がないため、当該押圧部における内周壁５の上部が外周壁１１に近づくように内容器２が傾かせられて、嵌合部１５と５個の嵌合凸部１０との嵌合が解け、内周壁５の中心軸線を挟んだ当該押圧部の対向部分におけるフランジ６が浮き上がり、この浮き上がったフランジ６と外周壁１１の上端面１６との間の隙間が拡大する。したがって、図１０に示すように、内容器２を容易に摘み上げることができる。 In the refill container 1 according to the present embodiment, theinner container 2 can be removed from the outer container 3 by the following procedure, for example. With the lid 4 removed, the user first presses the outer edge of theflange 6 of theinner container 2 downward in order to remove theinner container 2 from the outer container 3. At this time, as shown in FIG. 7, when the user presses the upperconvex portion 9 side portion (that is, the portion where the upperconvex portion 9 is formed in the circumferential direction) on the outer edge of theflange 6, the inner portion is formed. Since there is no fittingconvex portion 10 in the facing portion of the pressing portion sandwiching the central axis of theperipheral wall 5, theinner container 2 is tilted so that the lower portion of the innerperipheral wall 5 in the facing portion approaches the outerperipheral wall 11. , Thefitting portion 15 and the five fittingconvex portions 10 are disengaged, theflange 6 at the facing portion is lifted, and the gap between the raisedflange 6 and theupper end surface 16 of the outerperipheral wall 11 is expanded. do. Therefore, as shown in FIG. 8, theinner container 2 can be easily picked up. On the other hand, when the user presses the non-upperconvex portion 9 side portion (that is, the portion where the upperconvex portion 9 is not formed in the circumferential direction) on the outer edge of theflange 6, as shown in FIG. Since the pressing portion does not have the upperconvex portion 9, theinner container 2 is tilted so that the upper portion of the innerperipheral wall 5 in the pressing portion approaches the outerperipheral wall 11, and thefitting portion 15 and the five fitting convex portions are tilted. The fitting with 10 is released, theflange 6 at the portion facing the pressing portion sandwiching the central axis of the innerperipheral wall 5 is lifted, and the gap between the raisedflange 6 and theupper end surface 16 of the outerperipheral wall 11 is expanded. .. Therefore, as shown in FIG. 10, theinner container 2 can be easily picked up.

特に、本実施形態では、５個の上凸部９がフランジ６と内周壁５との連結部に設けられているので、フランジ６の外縁を押圧したときに内容器２を容易に傾かせることができる。また、本実施形態では、５個の上凸部９が環状凸部１６ａに当接可能であるので、フランジ６と外周壁１１の上端面１６との間の隙間を確保し易く、もって、内容器２の取り外しを容易にすることができる。 In particular, in the present embodiment, since the five upperconvex portions 9 are provided at the connecting portion between theflange 6 and the innerperipheral wall 5, theinner container 2 can be easily tilted when the outer edge of theflange 6 is pressed. Can be done. Further, in the present embodiment, since the five upperconvex portions 9 can come into contact with the annularconvex portions 16a, it is easy to secure a gap between theflange 6 and theupper end surface 16 of the outerperipheral wall 11, and thus the contents. Thevessel 2 can be easily removed.

前記の説明は、本発明の一実施形態を示したものにすぎず、特許請求の範囲を限定するものではない。前記の実施形態は、本開示の基礎的事項に基づいて、例えば以下のような、種々の変更が可能である。 The above description merely shows one embodiment of the present invention, and does not limit the scope of claims. Based on the basic matters of the present disclosure, the above-described embodiment can be modified in various ways, for example, as follows.

前記の実施形態では、５個の上凸部９は、フランジ６と内周壁５との連結部に設けられている。しかし、５個の上凸部９は、フランジ６の下面、又は内周壁５の外周面に設けてもよい。また、前記の実施形態では、５個の上凸部９は、外周壁１１の上端面１６に設けられた環状凸部１６ａに当接可能に設けられている。しかし、５個の上凸部９は、環状凸部１６ａを有さない外周壁１１の上端面１６に当接可能に設けてもよい。 In the above embodiment, the five upperconvex portions 9 are provided at the connecting portion between theflange 6 and the innerperipheral wall 5. However, the five upperconvex portions 9 may be provided on the lower surface of theflange 6 or the outer peripheral surface of the innerperipheral wall 5. Further, in the above-described embodiment, the five upperconvex portions 9 are provided so as to be able to come into contact with the annularconvex portions 16a provided on theupper end surface 16 of the outerperipheral wall 11. However, the five upperconvex portions 9 may be provided so as to be able to come into contact with theupper end surface 16 of the outerperipheral wall 11 that does not have the annularconvex portion 16a.

また、前記の実施形態では、５個の上凸部９及び５個の嵌合凸部１０は、内容器２の内壁８に設けられている。しかし、５個の上凸部９及び５個の嵌合凸部１０は、外容器３の外周壁１１に設けてもよい。この場合、例えば、外周壁１１は、上端面１６において周方向に全周に亘って等間隔で並ぶとともに、フランジ６の外縁より内側で内壁８（フランジ６）と上下方向に当接可能な凸状をなす、奇数個の上凸部と、外周壁１１の内周面において、当該奇数個の上凸部の下方で当該奇数個の上凸部と位置を揃えて周方向に並ぶとともに、内壁８に設けられた環状の嵌合部と嵌合可能な凸状をなす、奇数個の嵌合凸部と、を有する構成とすることができる。 Further, in the above embodiment, the five upperconvex portions 9 and the five fittingconvex portions 10 are provided on theinner wall 8 of theinner container 2. However, the five upperconvex portions 9 and the five fittingconvex portions 10 may be provided on the outerperipheral wall 11 of the outer container 3. In this case, for example, the outerperipheral wall 11 is arranged on theupper end surface 16 at equal intervals over the entire circumference in the circumferential direction, and is convex so as to be in contact with the inner wall 8 (flange 6) in the vertical direction inside the outer edge of theflange 6. On the inner peripheral surface of the odd-numbered upper convex portions and the outerperipheral wall 11, the odd-numbered upper convex portions are aligned with the odd-numbered upper convex portions below the odd-numbered upper convex portions and are aligned in the circumferential direction, and the inner wall is aligned. It is possible to have a configuration having an odd number of fitting convex portions forming a convex shape that can be fitted with the annular fitting portion provided in 8.
