本発明は、横断面視多角形状の外容器内に内容器を強固に保持できるとともに、内容器の取り外し時においては、内容器を容易に取り外することができる操作性に優れた二重容器を提供することを目的とする。 The present invention provides a double container excellent in operability in which the inner container can be firmly held in the outer container having a polygonal shape in cross-sectional view, and the inner container can be easily removed when the inner container is removed. The purpose is to provide.

上記課題を解決するために、本発明は以下の手段を提案している。
本発明に係る二重容器は、内容物が収容される内容器と、該内容器を着脱自在に収納する横断面視多角形状の外容器と、前記外容器の下端部に着脱自在に装着され、該外容器の下端開口を閉塞して前記内容器を前記外容器との間に保持する底蓋と、を備え、前記底蓋は、前記下端開口内に挿入された横断面視多角形状の枠体と、前記枠体の内側に前記外容器の容器軸回りに回転可能に配設された回転部材と、を備え、前記外容器の前記下端部には、前記容器軸回りの周方向に沿って間隔をあけて複数の係合部が形成され、前記回転部材には、前記係合部に前記容器軸方向に沿う前記外容器の内側から各別に係合する複数の被係合部が形成され、前記回転部材は、前記被係合部が前記係合部に係合し、前記容器軸方向に沿う前記底蓋の移動を規制する規制位置と、前記係合部及び前記被係合部が周方向に互いに離間し、前記容器軸方向に沿う前記底蓋の移動の規制を解除する解除位置と、の間を前記容器軸回りに回転可能に配設されていることを特徴としている。 In order to solve the above problems, the present invention proposes the following means.
A double container according to the present invention is detachably attached to an inner container in which contents are stored, an outer container having a polygonal shape in cross-sectional view for detachably storing the inner container, and a lower end portion of the outer container. A bottom cover that closes a lower end opening of the outer container and holds the inner container between the outer container and the bottom cover having a polygonal shape in a cross-sectional view inserted into the lower end opening. And a rotating member disposed inside the frame so as to be rotatable around the container axis of the outer container, and the lower end portion of the outer container has a circumferential direction around the container axis. A plurality of engaging portions are formed at intervals along the rotating member, and the rotating member has a plurality of engaged portions that are engaged with the engaging portions separately from the inside of the outer container along the container axial direction. The rotating member is formed so that the engaged portion engages with the engaging portion and restricts the movement of the bottom lid along the container axial direction. Between the restriction position to be released and the release position at which the engagement portion and the engaged portion are spaced apart from each other in the circumferential direction to release the restriction on the movement of the bottom lid along the container axial direction. It is characterized by being arranged rotatably.

このような特徴により、回転部材が上述の規制位置に位置しているときには、被係合部が係合部に係合するため、底蓋の、容器軸方向に沿う外容器の外側に向けた移動の規制が解除されるのを抑制できる。
一方で、底蓋の取り外し時においては、枠体に対して回転部材を回転させ、回転部材を上述した解除位置に位置させることで、係合部と被係合部との係合が解除されるため、底蓋の、容器軸方向に沿う外容器の外側に向けた移動の規制を解除できる。
この場合、係合部及び被係合部がそれぞれ複数ずつ設けられているので、底蓋を外容器に対して大きく回転移動させなくても、上述の規制位置と解除位置とを切り替えることが可能になり、底蓋を外容器に着脱する際の操作性を向上させることができる。また、係合部と被係合部とがアンダーカット嵌合ではなく回転部材を容器軸回りに回転移動させることにより互いに係合するので、例えば係合部及び被係合部のうち少なくとも一方の突出量を高くする等して互いの係合代を大きくしても、これらを互いに容易に係合させることができる。
以上により、横断面視多角形状の外容器内に内容器を強固に保持できるとともに、内容器の取り外し時においては、内容器を容易に取り外すことができる操作性に優れた二重容器を提供できる。 Due to such a feature, when the rotating member is located at the above-described restriction position, the engaged portion engages with the engaging portion, and therefore, the bottom lid is directed to the outside of the outer container along the container axial direction. It can suppress that the restriction | limiting of a movement is cancelled | released.
On the other hand, when the bottom lid is removed, the engagement between the engaging portion and the engaged portion is released by rotating the rotating member with respect to the frame and positioning the rotating member at the release position described above. Therefore, the restriction | limiting of the movement toward the outer side of the outer container along a container axial direction of a bottom cover can be cancelled | released.
In this case, a plurality of engaging portions and engaged portions are provided, so that the restriction position and the release position can be switched without greatly rotating the bottom lid with respect to the outer container. Thus, the operability when the bottom lid is attached to and detached from the outer container can be improved. Further, since the engaging portion and the engaged portion are engaged with each other by rotating the rotating member around the container axis instead of undercut fitting, for example, at least one of the engaging portion and the engaged portion These can be easily engaged with each other even if the engagement amount is increased by increasing the protrusion amount or the like.
As described above, the inner container can be firmly held in the outer container having a polygonal shape in cross section, and at the time of removing the inner container, it is possible to provide a double container excellent in operability in which the inner container can be easily removed. .

また、前記枠体には、前記被係合部における周方向の一端部に当接して前記回転部材を前記規制位置に位置決めする位置決め部が形成されていてもよい。 The frame body may be formed with a positioning portion that contacts the one end portion in the circumferential direction of the engaged portion to position the rotating member at the restriction position.

この場合、規制位置において、回転部材の周方向の一端側への移動が規制されるため、被係合部を係合部に容易、かつ確実に係合させることができる。 In this case, since the movement of the rotating member toward one end in the circumferential direction is restricted at the restriction position, the engaged portion can be easily and reliably engaged with the engaging portion.

また、前記回転部材の底壁部のうち、外周部分よりも前記容器軸に直交する径方向の内側に位置する部分に、径方向の外側から内側に向かうに従い前記容器軸方向に沿う前記外容器の内側に向けて窪むドーム部が形成されるとともに、前記ドーム部に前記容器軸方向に沿う前記外容器の外側に向けて摘み片が突設され、前記摘み片における前記容器軸方向に沿う前記外容器の外側の端部が、前記外周部分に対して前記容器軸方向に沿う同位置、または前記外周部分よりも前記容器軸方向に沿う前記外容器の内側に位置していてもよい。 Further, the outer container along the container axial direction as it goes from the outer side in the radial direction toward the inner side in the portion located on the inner side in the radial direction perpendicular to the container axis than the outer peripheral part of the bottom wall portion of the rotating member A dome part recessed toward the inside of the container is formed, and a knob piece projects from the dome part toward the outer side of the outer container along the container axial direction. The outer end of the outer container may be located at the same position along the container axial direction with respect to the outer peripheral part, or at the inner side of the outer container along the container axial direction with respect to the outer peripheral part.

この場合、摘み片を摘んで回転部材を操作できるため、操作性を向上させることができる。また、摘み片における容器軸方向に沿う外容器の外側の端部が、外周部分に対して容器軸方向に沿う同位置、または外周部分よりも容器軸方向に沿う外容器の内側に位置しているため、摘み片が外容器よりも容器軸方向に沿う外側に突出することがなく、二重容器を安定して接地させることができる。 In this case, since the rotary member can be operated by picking the knob, the operability can be improved. In addition, the outer end of the outer container along the container axial direction in the pick piece is located at the same position along the container axial direction with respect to the outer peripheral part, or inside the outer container along the container axial direction with respect to the outer peripheral part. Therefore, the knob piece does not protrude outward along the container axial direction from the outer container, and the double container can be stably grounded.

また、前記外容器は、前記内容器の肩部を覆うとともに、その内側に前記内容器の口部が挿入された肩カバーを備えていてもよい。 The outer container may include a shoulder cover that covers the shoulder of the inner container and into which the mouth of the inner container is inserted.

この場合、外容器のうち容器軸方向に沿う下端部とは反対側（肩カバー側）への内容器の移動を規制できるので、外容器内に内容器を確実に保持できる。 In this case, since the movement of the inner container to the opposite side (shoulder cover side) of the outer container along the container axial direction can be restricted, the inner container can be reliably held in the outer container.

本発明に係る二重容器によれば、横断面視多角形状の外容器内に内容器を強固に保持できるとともに、内容器の取り外し時においては、内容器を容易に取り外すことができる操作性に優れた二重容器を提供できる。 According to the double container according to the present invention, the inner container can be firmly held in the outer container having a polygonal shape in cross section, and the inner container can be easily removed when the inner container is removed. An excellent double container can be provided.

A plurality of projecting portions 78 projecting outward in the radial direction are formed on the outer surface of the peripheral wall portion 74 at intervals in the circumferential direction. The projecting portions 78 are undercut fitted to the projecting portions 72 of the frame body 61 described above, so that the rotating member 62 is held rotatably around the container axis O with respect to the frame body 61. In addition, as long as at least one of the protrusions 72 and 78 is formed over the entire circumference, the other may be intermittently formed in the circumferential direction. Moreover, as long as the stable mutual rotation is possible, both the protrusion parts 72 and 78 may be formed intermittently.

周壁部７４の上端縁には、径方向の外側に向けて突出するフランジ部８１が周壁部７４の全周に亘って形成されている。このフランジ部８１は、上述した枠体６１における内筒部７１の上方を跨ぐように延び、外周縁が内筒部７１よりも径方向の外側に位置している。
囲繞筒７５は、上述したフランジ部８１の外周縁から下方に向けて延設されている。囲繞筒７５は、図２に示すように、枠体６１の内筒部７１と、ガイド壁６９または外筒部６５と、の間に位置している。 At the upper end edge of the peripheral wall portion 74, a flange portion 81 that protrudes outward in the radial direction is formed over the entire periphery of the peripheral wall portion 74. The flange portion 81 extends so as to straddle the upper portion of the inner cylinder portion 71 in the frame body 61 described above, and the outer peripheral edge is located on the outer side in the radial direction with respect to the inner cylinder portion 71.
The surrounding cylinder 75 extends downward from the outer peripheral edge of the flange portion 81 described above. As shown in FIG. 2, the surrounding cylinder 75 is located between the inner cylinder portion 71 of the frame body 61 and the guide wall 69 or the outer cylinder portion 65.

ここで、図１〜３に示すように、囲繞筒７５の外面には、径方向の外側に向けて突出する被係合部８２が周方向に間隔をあけて複数形成されている。これら被係合部８２は、容器軸Ｏ方向に沿う縦断面視において、径方向の外側に向かうに従い先細る台形状に形成され、周方向に沿って延在している。また、被係合部８２のうち径方向の外側に位置する外周面は円弧状に形成されている。 Here, as shown in FIGS. 1 to 3, a plurality of engaged portions 82 protruding outward in the radial direction are formed on the outer surface of the surrounding cylinder 75 at intervals in the circumferential direction. These engaged portions 82 are formed in a trapezoidal shape that tapers toward the outside in the radial direction in the longitudinal sectional view along the container axis O direction, and extends along the circumferential direction. Moreover, the outer peripheral surface located in the radial direction outer side among the to-be-engaged parts 82 is formed in circular arc shape.

各被係合部８２は、上述した切欠き部６８内に配設され、切欠き部６８内で、外容器３の係合部２３に係合部２３の上方から各別に当接している。具体的に、各被係合部８２は、容器軸Ｏ方向から見て係合部２３及び切欠き部６８と重なる位置に配設され、底蓋４の外容器３に対する下方への移動が規制されている。本実施形態では、各被係合部８２は、各係合部２３と同数形成されるとともに、上述した各係合部２３にそれぞれ対応する位置に配設されている。図示の例では、囲繞筒７５において周方向に沿う９０度ごとの４箇所に被係合部８２が形成されている。 Each engaged portion 82 is disposed in the above-described notch portion 68, and in contact with the engaging portion 23 of the outer container 3 from above the engaging portion 23 in the notch portion 68. Specifically, each engaged portion 82 is disposed at a position overlapping the engaging portion 23 and the notch portion 68 when viewed from the container axis O direction, and the downward movement of the bottom lid 4 with respect to the outer container 3 is restricted. Has been. In the present embodiment, each engaged portion 82 is formed in the same number as each engaging portion 23, and is disposed at a position corresponding to each engaging portion 23 described above. In the example shown in the figure, engaged portions 82 are formed at four positions every 90 degrees along the circumferential direction in the surrounding cylinder 75.

各被係合部８２における周方向の中心を通り容器軸Ｏ方向に延びる被係合部８２の中心線は、上述した各主壁部６６の中心線に一致している。また、被係合部８２は、切欠き部６８内における周方向の一端側寄りに配置され、上述した切欠き部６８の上述した一端側の側縁部６８ａに近接または当接している。 The center line of the engaged portion 82 extending in the container axis O direction through the center in the circumferential direction of each engaged portion 82 coincides with the center line of each main wall portion 66 described above. Further, the engaged portion 82 is disposed closer to one end side in the circumferential direction in the notch portion 68, and is close to or abuts on the side edge portion 68 a on the one end side of the notch portion 68 described above.

そして、本実施形態の回転部材６２は、各被係合部８２が係合部２３に係合し、底蓋４の下方への移動を規制する規制位置と、被係合部８２及び係合部２３が周方向に互いに離間し、底蓋４の下方への移動の規制を解除する解除位置（図４〜６参照）と、の間を容器軸Ｏ回りに回転可能に配設されている。なお、図６（ｂ）に示す例では、解除位置において、各被係合部８２が切欠き部６８から退避して各角部１３，６７と径方向で対向している。
また、回転部材６２は、上述した規制位置において、被係合部８２における周方向に沿う一端部が、上述した切欠き部６８内で上述した一端側の側縁部６８ａに当接することで、それ以上の周方向に沿う一端側への回転移動が規制されている。一方、回転部材６２は、上述した解除位置において、被係合部８２における周方向に沿う他端部が、図６（ｂ）に示すように、周方向で隣り合う他の切欠き部６８における一端側の側縁部６８ａから延びるガイド壁６９の外側端部に当接することで、回転部材６２のそれ以上の周方向に沿う他端側への回転移動が規制されている。したがって、回転部材６２は、切欠き部６８における一端側の側縁部６８ａと、周方向で隣り合う他の切欠き部６８における一端側の側縁部６８ａから延びるガイド壁６９の外側端部と、の間の角度範囲で回転可能に構成されている。 The rotating member 62 according to the present embodiment includes a restriction position in which each engaged portion 82 engages with the engaging portion 23 and restricts the downward movement of the bottom lid 4, the engaged portion 82 and the engagement. The portions 23 are spaced apart from each other in the circumferential direction, and are disposed so as to be rotatable around the container axis O between a release position (see FIGS. 4 to 6) that releases the restriction of the downward movement of the bottom lid 4. . In the example shown in FIG. 6B, each engaged portion 82 is retracted from the notch 68 and opposed to each corner 13, 67 in the radial direction at the release position.
In addition, the rotating member 62 has one end portion along the circumferential direction of the engaged portion 82 in contact with the side edge portion 68a on the one end side in the above-described notch portion 68 at the above-described restriction position. Further rotational movement to the one end side along the circumferential direction is restricted. On the other hand, the rotating member 62 has the other end portion along the circumferential direction of the engaged portion 82 in the other notch portion 68 adjacent in the circumferential direction, as shown in FIG. By abutting the outer end of the guide wall 69 extending from the side edge 68a on the one end side, the rotational movement of the rotating member 62 toward the other end along the further circumferential direction is restricted. Therefore, the rotating member 62 includes a side edge 68a on one end side in the notch 68 and an outer end of the guide wall 69 extending from the side edge 68a on one end in the other notch 68 adjacent in the circumferential direction. It is configured to be rotatable in an angle range between.

また、オーバーキャップ５は、ポンプヘッド４６及び外容器３の肩カバー１５を覆うように配設されており、その下端縁が外容器３における縦筒部１７に外嵌されている。 The overcap 5 is disposed so as to cover the pump head 46 and the shoulder cover 15 of the outer container 3, and the lower end edge of the overcap 5 is externally fitted to the vertical cylinder portion 17 in the outer container 3.

次に、上述した二重容器１の作用について説明する。なお、以下の説明では、主として底蓋４の取り付け方法及び取り外し方法について説明する。
まず、外容器３内に内容器６を下方から挿入する。具体的に、内容器６の肩部３３が外容器３の肩カバー１５に下方から近接するように内容器６を挿入することで、内容器６の口部３７が外容器３の頂部開口１９内に挿入されるとともに、内容器６の胴部３２が外容器３の胴部１２内に嵌合される。 Next, the effect | action of the double container 1 mentioned above is demonstrated. In the following description, a method for attaching and removing the bottom lid 4 will be mainly described.
First, the inner container 6 is inserted into the outer container 3 from below. Specifically, by inserting the inner container 6 so that the shoulder 33 of the inner container 6 is close to the shoulder cover 15 of the outer container 3 from below, the mouth 37 of the inner container 6 is the top opening 19 of the outer container 3. The body 32 of the inner container 6 is fitted into the body 12 of the outer container 3 while being inserted into the body.

次に、内容器６の口部３７に吐出器３１を装着する。具体的に、吐出器３１のポンプ本体５２及び吸上筒５４を口部３７内に挿入するとともに、取付キャップ４４の装着筒４５を内容器６の口部３７に螺着する。これにより、取付キャップ４４の外装筒４８と、内容器６の肩部３３と、の間で外容器３の肩カバー１５を容器軸Ｏ方向に挟んだ状態で、カートリッジ体２が外容器３にセットされる。このとき、外装筒４８の下端縁が外容器３の上段部１８に容器軸Ｏ方向で対向しているため、カートリッジ体２の外容器３に対する下方移動を規制して、カートリッジ体２が下端開口２４から抜けてしまうのを防ぐことができる。 Next, the discharger 31 is attached to the mouth 37 of the inner container 6. Specifically, the pump body 52 and the suction cylinder 54 of the discharger 31 are inserted into the mouth part 37, and the mounting cylinder 45 of the mounting cap 44 is screwed to the mouth part 37 of the inner container 6. Thereby, the cartridge body 2 is attached to the outer container 3 in a state where the shoulder cover 15 of the outer container 3 is sandwiched between the outer cylinder 48 of the mounting cap 44 and the shoulder portion 33 of the inner container 6 in the container axis O direction. Set. At this time, since the lower end edge of the outer cylinder 48 faces the upper step portion 18 of the outer container 3 in the container axis O direction, the cartridge body 2 is restricted from moving downward relative to the outer container 3 so that the cartridge body 2 is opened at the lower end. It can be prevented from coming out of 24.

続いて、底蓋４を外容器３に装着する。具体的には、図４に示すように、枠体６１に対して回転部材６２を容器軸Ｏ回りに回転させ、上述した解除位置に位置させる。すなわち、解除位置において、被係合部８２は切欠き部６８内から退避した位置に配置される。そして、底蓋４と外容器３との間で、角部１３，６７同士、及び主壁部１４，６６同士の周方向の位置を合わせた状態で、底蓋４を下方から外容器３内に挿入する（図５参照）。 Subsequently, the bottom lid 4 is attached to the outer container 3. Specifically, as shown in FIG. 4, the rotating member 62 is rotated around the container axis O with respect to the frame body 61 and is positioned at the release position described above. That is, at the release position, the engaged portion 82 is disposed at a position retracted from the notch 68. And in the state which match | combined the circumferential position of corner parts 13 and 67 and main wall parts 14 and 66 between the bottom cover 4 and the outer container 3, the bottom cover 4 is put in the outer container 3 from the downward direction. (See FIG. 5).

図６に示すように、底蓋４を外容器３内に挿入すると、枠体６１における外筒部６５の上端縁が外容器３の段差部２１に近接または当接するとともに、各切欠き部６８内に外容器３の係合部２３が収容される。
続いて、枠体６１に対して回転部材６２を容器軸Ｏ回りに回転させ、被係合部８２が係合部２３に係合する規制位置に位置させる。具体的には、摘み片７７を摘んだ状態で回転部材６２を回転させると、回転部材６２の被係合部８２が切欠き部６８内における周方向の他端側から進入する。そして、被係合部８２は、切欠き部６８内における周方向の一端側において、係合部２３と容器軸Ｏ方向で重なる。これにより、被係合部８２が、切欠き部６８内で外容器３の係合部２３に係合部２３の上方から当接して、底蓋４の下方への移動が規制される。
以上により、底蓋４の取り付けが完了する。なお、規制位置において、被係合部８２は、周方向に沿う一端部が側縁部６８ａに当接することで、回転部材６２のそれ以上の周方向に沿う一端側への回転移動が規制されている。 As shown in FIG. 6, when the bottom lid 4 is inserted into the outer container 3, the upper end edge of the outer cylinder portion 65 in the frame body 61 comes close to or abuts on the stepped portion 21 of the outer container 3 and each notch portion 68. The engaging portion 23 of the outer container 3 is accommodated inside.
Subsequently, the rotating member 62 is rotated around the container axis O with respect to the frame body 61, and the engaged portion 82 is positioned at a restriction position where the engaged portion 82 is engaged with the engaging portion 23. Specifically, when the rotary member 62 is rotated in a state where the knob piece 77 is picked, the engaged portion 82 of the rotary member 62 enters from the other end side in the circumferential direction in the notch portion 68. The engaged portion 82 overlaps with the engaging portion 23 in the container axis O direction at one end side in the circumferential direction in the notch portion 68. As a result, the engaged portion 82 comes into contact with the engaging portion 23 of the outer container 3 from above the engaging portion 23 in the notch portion 68, and the downward movement of the bottom lid 4 is restricted.
Thus, the attachment of the bottom cover 4 is completed. At the restricting position, the engaged portion 82 has its one end along the circumferential direction abutting against the side edge 68a, so that the rotational movement of the rotating member 62 toward the one end along the further circumferential direction is restricted. ing.

次に、カートリッジ体２を外容器３から取り外す際は、まず、枠体６１に対して回転部材６２を容器軸Ｏ回りに回転させ、上述した解除位置に位置させる。これにより、被係合部８２及び係合部２３が周方向に互いに離間するとともに、切欠き部６８から退避することで、被係合部８２の下方への移動の規制が解除される。
次に、底蓋４を下方に向けて引き抜く。すると、外容器３の係合部２３が切欠き部６８から退避して、底蓋４が外容器３から取り外される。
その後、内容器６の口部３７から吐出器３１（取付キャップ４４）を取り外した後、内容器６を外容器３から引き抜く。そして、新しい内容器６を外容器３内に挿入するとともに、吐出器３１を装着した後、上述した方法により底蓋４を外容器３に再度取り付けることで、カートリッジ体２の交換作業が完了する。 Next, when removing the cartridge body 2 from the outer container 3, first, the rotating member 62 is rotated around the container axis O with respect to the frame body 61 and positioned at the release position described above. As a result, the engaged portion 82 and the engaging portion 23 are separated from each other in the circumferential direction and retracted from the notch portion 68, whereby the restriction on the downward movement of the engaged portion 82 is released.
Next, the bottom lid 4 is pulled out downward. Then, the engaging part 23 of the outer container 3 is retracted from the notch part 68, and the bottom cover 4 is removed from the outer container 3.
Thereafter, the discharger 31 (mounting cap 44) is removed from the mouth portion 37 of the inner container 6, and then the inner container 6 is pulled out from the outer container 3. Then, after the new inner container 6 is inserted into the outer container 3 and the discharge device 31 is mounted, the bottom lid 4 is reattached to the outer container 3 by the method described above, whereby the replacement operation of the cartridge body 2 is completed. .

このように、本実施形態の二重容器１によれば、回転部材６２が規制位置に位置しているときには、被係合部８２が係合部２３に係合するため、底蓋４の、下方への移動の規制が解除されるのを抑制できる。
一方で、底蓋４の取り外し時においては、枠体６１に対して回転部材６２を回転させ、回転部材６２を上述した解除位置に位置させることで、係合部２３と被係合部８２との係合が解除されるため、底蓋４の、下方への移動の規制を解除できる。
この場合、係合部２３及び被係合部８２がそれぞれ複数ずつ設けられているので、底蓋４を外容器３に対して大きく回転移動させなくても、上述の規制位置と解除位置とを切り替えることが可能になり、底蓋４を外容器３に着脱する際の操作性を向上させることができる。また、係合部２３と被係合部８２とがアンダーカット嵌合ではなく回転部材６２を容器軸Ｏ回りに回転移動させることにより互いに係合するので、例えば係合部２３及び被係合部８２のうち少なくとも一方の突出量を高くする等して互いの係合代を大きくしても、これらを互いに容易に係合させることができる。
以上により、横断面視多角形状の外容器３内にカートリッジ体２を強固に保持できるとともに、カートリッジ体２の取り外し時においては、カートリッジ体２を容易に取り外すことができる操作性に優れた二重容器１を提供できる。 Thus, according to the double container 1 of the present embodiment, when the rotating member 62 is located at the restricting position, the engaged portion 82 engages with the engaging portion 23, so It is possible to prevent the downward movement restriction from being released.
On the other hand, when removing the bottom lid 4, the rotating member 62 is rotated with respect to the frame body 61, and the rotating member 62 is positioned at the release position described above. Since the engagement is released, the restriction on the downward movement of the bottom lid 4 can be released.
In this case, since a plurality of engaging portions 23 and a plurality of engaged portions 82 are provided, the above-described restriction position and release position can be achieved without the bottom cover 4 being rotated and moved greatly with respect to the outer container 3. It becomes possible to switch, and the operativity at the time of attaching / detaching the bottom cover 4 to the outer container 3 can be improved. Further, since the engaging portion 23 and the engaged portion 82 are engaged with each other by rotating the rotating member 62 around the container axis O instead of undercut fitting, for example, the engaging portion 23 and the engaged portion Even if the amount of mutual engagement is increased by increasing the amount of protrusion of at least one of 82, these can be easily engaged with each other.
As described above, the cartridge body 2 can be firmly held in the outer container 3 having a polygonal shape in cross section, and the cartridge body 2 can be easily detached when the cartridge body 2 is removed. A container 1 can be provided.

また、被係合部８２のうち周方向の一端部に当接して回転部材６２を規制位置に位置決めする位置決め部（切欠き部６８の一端側の側縁部６８ａ）が形成されているため、規制位置において、回転部材６２の周方向の一端側への移動を規制できる。そのため、被係合部８２を係合部２３に容易、かつ確実に係合させることができる。 In addition, a positioning portion (a side edge portion 68a on one end side of the notch portion 68) that contacts the one end portion in the circumferential direction of the engaged portion 82 and positions the rotating member 62 at the restriction position is formed. In the restricting position, the movement of the rotating member 62 toward one end side in the circumferential direction can be restricted. Therefore, the engaged portion 82 can be easily and reliably engaged with the engaging portion 23.

さらに、摘み片７７を摘んで回転部材６２を操作できるため、操作性を向上させることができる。また、摘み片７７の下面が、底壁部７３の外周部分７３ａに対して面一に配置されているため、摘み片７７が外容器３よりも下方に突出することがなく、二重容器１を安定して接地させることができる。
また、外容器３が、内容器６の肩部３３を覆うとともに、その内側に内容器６の口部３７が挿入された肩カバー１５を備えているため、上方への内容器６の移動を規制でき、外容器３内に内容器６を確実に保持できる。 Further, since the rotary member 62 can be operated by picking the knob 77, the operability can be improved.
