以下、図１〜図５を参照して、本発明の一実施形態に係る二重容器１について詳細に例示説明する。なお、本明細書において、上下方向とは、内容器１０及び外容器２０の中心軸線Ｏに沿う方向を意味し、上方とは内容器１０の内容物収容部１１の開口部１２が位置する側（例えば、図１における上方）、下方とは内容物収容部１１の底壁部１４が位置する側（例えば、図１における下方）を意味するものとする。   Hereinafter, with reference to FIGS. 1-5, the double container 1 which concerns on one Embodiment of this invention is illustrated and demonstrated in detail. In the present specification, the vertical direction means a direction along the center axis O of the inner container 10 and the outer container 20, and the upper side is the side where the opening 12 of the content container 11 of the inner container 10 is located. (For example, the upper side in FIG. 1) and the lower side mean the side (for example, the lower side in FIG. 1) on which the bottom wall portion 14 of the content container 11 is located.

図１に示すように、本実施形態に係る二重容器１は、レフィル用の内容器１０と、外容器２０と、回動部材３０と、外容器キャップ４０とを備えている。   As shown in FIG. 1, the double container 1 according to the present embodiment includes an inner container 10 for refilling, an outer container 20, a rotating member 30, and an outer container cap 40.

内容器１０は、軸線Ｏを中心とする有底筒状の内容物収容部１１を備えている。すなわち、内容物収容部１１は、その上部に開口部１２を形成すると共に、周壁部１３及び底壁部１４とを有する。周壁部１３の外周面上部には、環状の外向き凸部１５（嵌合部）が設けられている。また、周壁部１３の上端部には、径方向外側に延びる円環状のフランジ部１６が設けられている。さらに周壁部１３の外周面には、雄ねじ部１７が設けられており、雄ねじ部１７の下方には上下方向に延びる縦リブ１８（凸部）が突設されている。本実施形態において縦リブ１８は、周壁部１３の周方向に間隔をあけて４箇所に均等配置されているが、これに限られるものではない。   The inner container 10 includes a bottomed cylindrical content storage portion 11 centering on the axis O. That is, the content accommodating part 11 forms the opening part 12 in the upper part, and has the surrounding wall part 13 and the bottom wall part 14. As shown in FIG. An annular outward convex part 15 (fitting part) is provided on the outer peripheral surface upper part of the peripheral wall part 13. Further, an annular flange portion 16 extending radially outward is provided at the upper end portion of the peripheral wall portion 13. Further, a male screw portion 17 is provided on the outer peripheral surface of the peripheral wall portion 13, and a vertical rib 18 (convex portion) extending in the vertical direction is projected below the male screw portion 17. In the present embodiment, the vertical ribs 18 are evenly arranged at four locations at intervals in the circumferential direction of the peripheral wall portion 13, but are not limited thereto.

また、内容器１０は、未使用の状態では、図２（ａ）に示すように、内容器キャップ５０が装着されることで内容物収容部１１の開口部１２が閉塞され、クリーム等の内容物Ｃの品質が維持されるようになっている。内容器キャップ５０は、円板状の天壁部５１と、天壁部５１の外縁部から垂下する円筒状の外壁部５２とを備えている。また、内容器キャップ５０は、外壁部５２の内側で天壁部５１の下面から垂下して周壁部１３の内周面に当接する封止筒５３を備えている。外壁部５２の内周面には、内容器１０のフランジ部１６に嵌合する環状凸部５４が設けられている。また、外壁部５２の下端部には、外側に延びるフランジ５５が設けられている。なお、内容器キャップ５０の構成は、特に限定されるものではなく、開口部１２を塞いでクリーム等の内容物Ｃの品質が維持されるようになっていれば任意の構造のキャップを用いることができ、図２（ｂ）に示すように、周壁部１３の上面にシール部材５６を剥離可能に貼着した構成とすることも可能である。   Further, when the inner container 10 is not used, as shown in FIG. 2A, the inner container cap 50 is attached to close the opening 12 of the content container 11 and the contents such as cream. The quality of the object C is maintained. The inner container cap 50 includes a disk-shaped top wall 51 and a cylindrical outer wall 52 that hangs down from the outer edge of the top wall 51. Further, the inner container cap 50 includes a sealing cylinder 53 that hangs down from the lower surface of the top wall portion 51 inside the outer wall portion 52 and contacts the inner peripheral surface of the peripheral wall portion 13. On the inner peripheral surface of the outer wall portion 52, an annular convex portion 54 that fits into the flange portion 16 of the inner container 10 is provided. Further, a flange 55 extending outward is provided at the lower end of the outer wall portion 52. The configuration of the inner container cap 50 is not particularly limited, and a cap having an arbitrary structure is used as long as the quality of the content C such as cream is maintained by closing the opening 12. As shown in FIG. 2B, it is possible to adopt a configuration in which the seal member 56 is detachably attached to the upper surface of the peripheral wall portion 13.

外容器２０は、図１に示すように、内容器１０を収納可能な軸線Ｏを中心とする有底筒状の内容器収納部２１を備えている。すなわち、内容器収納部２１は、その上部に開口部２２を形成すると共に、側壁部２３及び底壁部２４とを有する。側壁部２３の上端部には、外周面に雄ねじ２５を設けた口部２６が設けられている。口部２６は、その外径が口部２６の下方の側壁部２３よりも小さく、その内径は大きくなるよう形成されている。口部２６の上方には、さらに外径が小さい上端筒部２７が設けられ、上端筒部２７の外周面には、外向き凸部２８（嵌合保持部）が設けられている。側壁部２３の内周面には、縦リブ１８（凸部）が嵌り込むことで外容器２０に対する内容器１０の回動を防止する縦溝２９（凹部）が設けられている。すなわち、内容器１０は、外容器２０に対して中心軸線Ｏの周りで回動不能に取付けられる構成とされている。   As shown in FIG. 1, the outer container 20 includes a bottomed cylindrical inner container storage portion 21 centering on an axis O that can store the inner container 10. That is, the inner container storage portion 21 has an opening 22 at the top thereof, and has a side wall portion 23 and a bottom wall portion 24. At the upper end portion of the side wall portion 23, a mouth portion 26 having an external thread 25 on the outer peripheral surface is provided. The mouth portion 26 is formed so that its outer diameter is smaller than the side wall portion 23 below the mouth portion 26 and its inner diameter is larger. An upper end cylindrical portion 27 having a smaller outer diameter is provided above the mouth portion 26, and an outward convex portion 28 (fitting holding portion) is provided on the outer peripheral surface of the upper end cylindrical portion 27. A longitudinal groove 29 (concave portion) is provided on the inner peripheral surface of the side wall portion 23 to prevent the inner container 10 from rotating relative to the outer container 20 by fitting the longitudinal rib 18 (convex portion). That is, the inner container 10 is configured to be non-rotatable around the central axis O with respect to the outer container 20.

回動部材３０は、内容器収納部２１における側壁部２３の上端部に、中心軸線Ｏの周りで回動可能に取付けられている。回動部材３０は環状（リング状）に形成され、口部２６及び上端筒部２７の内側に配置される円筒状の筒状壁３１と、筒状壁３１の上端部から径方向外側に延びる円環状のフランジ部３２と、フランジ部３２の外周縁から垂下する外周壁３３とを有する。筒状壁３１の内周面には、内容器１０の雄ねじ部１７に係合する雌ねじ部３４が設けられている。なお、雄ねじ部１７及び雌ねじ部３４は多条ねじとすることが好ましいが、これに限定されず、一条ねじ等とすることも可能である。雌ねじ部３４の上方には、外向き凸部１５（嵌合部）と嵌合して、内容器１０の抜け出しを妨げる内向き凸部３５（嵌合部）が設けられている。また、外周壁３３の内周面には、外向き凸部２８（嵌合保持部）に嵌合する内向き凸部３６（嵌合保持部）が設けられており、外容器２０からの回動部材３０の抜け出しを防止している。また、フランジ部３２の下面には、回動部材３０を回動させた際に上端筒部２７の上面２７ａに摺接する第１突起部３２ａが設けられている。さらに、外周壁３３の下面には、回動部材３０を回動させた際に口部２６の上面２６ａに摺接する第２突起部３３ａが設けられている。なお、本実施形態においては、第１突起部３２ａが上端筒部２７の上面２７ａに当接し、また、第２突起部３３ａが口部２６の上面２６ａに当接することで回動部材３０が外容器２０に下方から支持される構成としているが、これに限られるものではなく、少なくとも筒状壁３１、フランジ部３２、外周壁３３の何れかの下面が外容器２０によって下方から支持されていればよい。   The rotating member 30 is attached to the upper end portion of the side wall portion 23 of the inner container storage portion 21 so as to be rotatable around the central axis O. The rotating member 30 is formed in an annular shape (ring shape), and has a cylindrical tubular wall 31 disposed inside the mouth portion 26 and the upper end tubular portion 27, and extends radially outward from the upper end portion of the tubular wall 31. An annular flange portion 32 and an outer peripheral wall 33 depending from the outer peripheral edge of the flange portion 32 are provided. On the inner peripheral surface of the cylindrical wall 31, a female screw portion 34 that engages with the male screw portion 17 of the inner container 10 is provided. In addition, although it is preferable that the external thread part 17 and the internal thread part 34 are a multi-thread, it is not limited to this, A single thread etc. can also be used. Above the female screw portion 34, an inward convex portion 35 (fitting portion) that is fitted to the outward convex portion 15 (fitting portion) and prevents the inner container 10 from coming out is provided. Further, the inner peripheral surface of the outer peripheral wall 33 is provided with an inward convex portion 36 (fitting holding portion) that is fitted to the outward convex portion 28 (fitting holding portion). The moving member 30 is prevented from coming out. Further, the lower surface of the flange portion 32 is provided with a first protrusion portion 32a that is in sliding contact with the upper surface 27a of the upper end cylindrical portion 27 when the rotating member 30 is rotated. Further, a second protrusion 33 a that slides on the upper surface 26 a of the mouth portion 26 when the rotating member 30 is rotated is provided on the lower surface of the outer peripheral wall 33. In the present embodiment, the first projecting portion 32 a contacts the upper surface 27 a of the upper end cylindrical portion 27, and the second projecting portion 33 a contacts the upper surface 26 a of the mouth portion 26, so that the rotating member 30 is removed. Although it is configured to be supported by the container 20 from below, it is not limited to this, and at least the lower surface of the cylindrical wall 31, the flange portion 32, or the outer peripheral wall 33 is supported from below by the outer container 20. That's fine.

ここで、図３（ａ）は、図１に示す状態の二重容器１から外容器キャップ４０を取外した状態を表す平面図であり、図３（ｂ）は、一部断面側面図である。外周壁３３の外周面３３ｂは、図３（ａ）に示すように、平面視で正２０角形となるように形成されており、単純な円筒状の外周面に比べて、回動部材３０を回動させる際に把持し易く、滑り難くなっている。なお、外周壁３３の外周面３３ｂの形状は特に限定されるものではないが、上記の理由から平面視で多角形状とすることが好ましい。   Here, FIG. 3A is a plan view showing a state in which the outer container cap 40 is removed from the double container 1 in the state shown in FIG. 1, and FIG. 3B is a partial cross-sectional side view. . As shown in FIG. 3A, the outer peripheral surface 33b of the outer peripheral wall 33 is formed to be a regular decagon in a plan view, and the rotating member 30 is formed in comparison with a simple cylindrical outer peripheral surface. It is easy to grip when turning and is difficult to slip. Although the shape of the outer peripheral surface 33b of the outer peripheral wall 33 is not particularly limited, it is preferably a polygonal shape in plan view for the above reasons.

外容器キャップ４０は、図１に示すように、円筒状の外壁部４１と、外壁部４１の上端部を閉塞するドーム状の天壁部４２とを備えている。外壁部４１の内周面には、前述した雄ねじ２５と螺合する雌ねじ４３が設けられている。天壁部４２の下面には、円板状のパッキン４４が貼着されており、内容器１０のフランジ部１６の上面に形成された円環状のシール突起１６ａとパッキン４４とが密接することで、内容物収容部１１が密封されるようになっている。なお、天壁部４２はドーム状に限らず、平面状又は凹面状など、任意の形状であってもよい。また、本実施例ではパッキン４４を貼着にて組付けているが、これに限られるものではなく、外容器キャップ４０の外壁部４１内周面に凸部を設け、乗越えることで組付けるなど、パッキン４４が脱落しない程度に組付けられていればよく、その組付け方法は適宜選択可能である。   As shown in FIG. 1, the outer container cap 40 includes a cylindrical outer wall portion 41 and a dome-shaped top wall portion 42 that closes the upper end portion of the outer wall portion 41. On the inner peripheral surface of the outer wall portion 41, a female screw 43 that is screwed with the male screw 25 described above is provided. A disc-shaped packing 44 is attached to the lower surface of the top wall portion 42, and the annular seal protrusion 16 a formed on the upper surface of the flange portion 16 of the inner container 10 and the packing 44 are brought into close contact with each other. The content container 11 is sealed. The top wall portion 42 is not limited to a dome shape, and may have an arbitrary shape such as a flat shape or a concave shape. Further, in this embodiment, the packing 44 is assembled by sticking, but the present invention is not limited to this, and a convex portion is provided on the inner peripheral surface of the outer wall 41 of the outer container cap 40 and is assembled by getting over. As long as the packing 44 is assembled to such an extent that it does not fall off, the assembling method can be appropriately selected.

かかる構成になる二重容器１によれば、内容物Ｃを使い切った際などに、以下の要領で内容器１０を新たな内容器１０と交換することができる。すなわち、まず、図１に示す状態から外容器キャップ４０を取外し、次いで図３（ｂ）に示すように、回動部材３０を外容器２０に対して中心軸線Ｏの周りで一方側に回動させる。内容器１０は外容器２０に対して回動不能とされているため、回動部材３０のみが回動し、内容器１０の雄ねじ部１７と回動部材３０の雌ねじ部３４が係合することにより、内容器１０と回動部材３０との間には、上下方向に相互に離間する方向の力が作用する。回動部材３０は外容器２０に支持されて下方への移動を規制されているため、内容器１０が上方に移動する。この時、外向き凸部１５と内向き凸部３５との嵌合が解除されるため、あとは図４（ａ）に示すように、上方へ移動した内容器１０をさらに引き出すだけで、内容器１０を外容器２０から取り出し、そのままの状態で破棄することができる。図４（ｂ）は、内容器１０を取外した状態を示している。このようにして内容器１０を取り出した後は、図２（ａ）、（ｂ）に示したような新たな内容器１０から、内容器キャップ５０またはシール部材５６を取外し、図５（ａ）に示すように、新たな内容器１０を外容器２０の内容器収納部２１に挿入していく。新たな内容器１０を押し込んでいくと、内容器１０の雄ねじ部１７と回動部材３０の雌ねじ部３４が係合し、内容器１０を取外す場合と逆側（他方側）に回動部材３０が外容器２０に対して回動する。図５（ｂ）に示す状態まで内容器１０を押し込むことで、内容器１０の交換が完了する。この時、外向き凸部１５と内向き凸部３５とが互いに乗り越え嵌合することで内容器１０の抜け出しを妨げることができる。なお、新たな内容器１０を取り付ける方法としては、内容器１０を押し込まずに、回動部材３０の回動操作によって内容器１０を下方移動させてもよい。すなわち、内容器収納部２１に新たな内容器１０を置いた状態で、回動部材３０を外容器２０に対して他方側に回動させることにより、雄ねじ部１７と雌ねじ部３４を係合させて内容器１０を下方に移動させ、内容器１０を図５（ｂ）に示す状態まで挿入することも可能である。   According to the double container 1 having such a configuration, when the contents C are used up, the inner container 10 can be replaced with a new inner container 10 in the following manner. That is, first, the outer container cap 40 is removed from the state shown in FIG. 1, and then the rotating member 30 is rotated to one side around the central axis O with respect to the outer container 20, as shown in FIG. Let Since the inner container 10 is not rotatable with respect to the outer container 20, only the rotating member 30 is rotated, and the male screw portion 17 of the inner container 10 and the female screw portion 34 of the rotating member 30 are engaged. As a result, a force in a direction away from each other in the vertical direction acts between the inner container 10 and the rotating member 30. Since the rotation member 30 is supported by the outer container 20 and restricted from moving downward, the inner container 10 moves upward. At this time, since the fitting between the outward convex portion 15 and the inward convex portion 35 is released, the content can be simply extracted by further pulling the inner container 10 moved upward as shown in FIG. The container 10 can be taken out of the outer container 20 and discarded as it is. FIG. 4B shows a state where the inner container 10 is removed. After taking out the inner container 10 in this way, the inner container cap 50 or the seal member 56 is removed from the new inner container 10 as shown in FIGS. 2A and 2B, and FIG. As shown, the new inner container 10 is inserted into the inner container storage portion 21 of the outer container 20. When the new inner container 10 is pushed in, the male threaded portion 17 of the inner container 10 and the female threaded portion 34 of the rotating member 30 are engaged, and the rotating member 30 is on the opposite side (the other side) from the case where the inner container 10 is removed. Rotates relative to the outer container 20. By pushing the inner container 10 to the state shown in FIG. 5B, the replacement of the inner container 10 is completed. At this time, the outward convex portion 15 and the inward convex portion 35 get over and fit with each other, thereby preventing the inner container 10 from coming out. In addition, as a method of attaching a new inner container 10, the inner container 10 may be moved downward by rotating the rotating member 30 without pushing the inner container 10 in. That is, with the new inner container 10 placed in the inner container storage portion 21, the male screw portion 17 and the female screw portion 34 are engaged by rotating the rotating member 30 to the other side with respect to the outer container 20. It is also possible to move the inner container 10 downward and insert the inner container 10 to the state shown in FIG.

以上説明したように、本実施形態に係る二重容器１は、外容器２０の内容器収納部２１の上端部に設けた回動部材３０を一方側に回動させると、回動部材３０の雌ねじ部３４が内容器１０の雄ねじ部１７と係合して、内容器１０を上方へ移動させる構成となっている。したがって、内容器１０の交換に際し、比較的小さな力で内容器１０を容易に取外すことができる。また、使用済みの内容器１０を取外した後は、新たな内容器１０を外容器２０の内容器収納部２１に押し込む操作、あるいは回動部材３０の回動操作のみで内容器１０の取付けが完了するため、容易に新たな内容器１０を取付けることができる。   As described above, the double container 1 according to the present embodiment allows the rotating member 30 of the outer container 20 to rotate to the one side when the rotating member 30 provided at the upper end of the inner container storage unit 21 is rotated to one side. The internal thread portion 34 is engaged with the external thread portion 17 of the inner container 10 to move the inner container 10 upward. Therefore, when replacing the inner container 10, the inner container 10 can be easily removed with a relatively small force. In addition, after the used inner container 10 is removed, the inner container 10 can be attached only by an operation of pushing a new inner container 10 into the inner container storage portion 21 of the outer container 20 or a rotating operation of the rotating member 30. Since it is completed, a new inner container 10 can be easily attached.

また、内容器１０を取外すために、内容器１０を押圧するための貫通孔や切欠き部を外容器２０に設ける必要もない。したがって、本実施形態によれば、内容器１０の交換を容易化すると共に容器の外観設計の自由度を向上することができる。   Further, it is not necessary to provide the outer container 20 with a through hole or a notch for pressing the inner container 10 in order to remove the inner container 10. Therefore, according to the present embodiment, the exchange of the inner container 10 can be facilitated and the degree of freedom in designing the appearance of the container can be improved.

また、本実施形態に係る二重容器１では、内容器１０に設けた外向き凸部１５と回動部材３０に設けた内向き凸部３５とが、内容器１０を回動部材３０の内側に挿入した際に互いに乗り越え嵌合して、内容器１０の抜け出しを妨げる構成により、外容器キャップ４０を外した状態（図３（ｂ）の状態）において内容器１０が脱落することを防止することができる。   Further, in the double container 1 according to the present embodiment, the outward convex portion 15 provided in the inner container 10 and the inward convex portion 35 provided in the rotating member 30 make the inner container 10 inside the rotating member 30. The inner container 10 is prevented from falling off when the outer container cap 40 is removed (the state shown in FIG. 3 (b)) by preventing the inner container 10 from slipping out by fitting over each other when inserted into the container. be able to.

また、本実施形態に係る二重容器１では、雄ねじ部１７と雌ねじ部３４を多条ねじとしたことにより、一条ねじとした場合に比べて、内容器１０を上方に移動させる際の回動部材３０の回動距離を小さくすることができる。すなわち、回動部材３０を少し回動させるだけで、内容器１０を取外すことが可能となるため、内容器１０の取外しがさらに容易となる。また、雄ねじ部１７と雌ねじ部３４を多条ねじとしたことにより、新たな内容器１０を取付ける際の回動部材３０の回動距離が小さくなるため、内容器１０の取付けも容易となる。   Moreover, in the double container 1 which concerns on this embodiment, since the external thread part 17 and the internal thread part 34 were made into the multi-thread screw, compared with the case where it is set as a single thread thread, the rotation at the time of moving the inner container 10 upwards The rotation distance of the member 30 can be reduced. That is, since the inner container 10 can be removed by slightly rotating the rotating member 30, the inner container 10 can be removed more easily. In addition, since the male screw portion 17 and the female screw portion 34 are multi-threaded screws, the rotation distance of the rotation member 30 when the new inner container 10 is attached is reduced, so that the inner container 10 can be easily attached.

また、本実施形態の二重容器１では、フランジ部３２の下面に設けた第１突起部３２ａの先端が上端筒部２７の上面２７ａに当接し、外周壁３３の第２突起部３３ａの先端が口部２６の上面２６ａに当接することで、回動部材３０が外容器２０に下方から支持される構成としている。これにより、回動部材３０を回転させた際の摺動抵抗が低減されるため、内容器１０の取外し及び取付けがさらに容易となる。   In the double container 1 of the present embodiment, the tip of the first protrusion 32 a provided on the lower surface of the flange portion 32 abuts on the upper surface 27 a of the upper end cylindrical portion 27, and the tip of the second protrusion 33 a of the outer peripheral wall 33. Is in contact with the upper surface 26a of the mouth portion 26, so that the rotating member 30 is supported by the outer container 20 from below. Thereby, since the sliding resistance at the time of rotating the rotation member 30 is reduced, the removal and attachment of the inner container 10 are further facilitated.

前述したところは、本発明の一実施形態を示したにすぎず、特許請求の範囲において、種々の変更を加えることができる。例えば、先の実施形態では外容器２０と外容器キャップ４０とがねじ係合する構成としたが、これに限定されず、着脱可能にアンダーカット係合する構成とすることも可能である。   The above description shows only one embodiment of the present invention, and various modifications can be made within the scope of the claims. For example, in the previous embodiment, the outer container 20 and the outer container cap 40 are configured to be screw-engaged. However, the present invention is not limited to this, and a configuration in which the undercut engagement is detachable is also possible.
