まず、図２に示す二重容器１０において、前記案内凸部２０ｃが外装容器１５の上端部外周面に形成された案内溝２１のうち第２溝２１ｂおよび連結溝２１ｃをこの順に沿って移動するように、カバー部２０を前記中心軸線Ｏ回りに回転させて、このカバー部２０とともに注出部１６を取り外す。 Next, a method of removing the used interior container 14 in the above double container 10 will be described.
First, in the double container 10 shown in FIG. 2, the guide convex portion 20 c moves along the second groove 21 b and the connecting groove 21 c in this order among the guide grooves 21 formed on the outer peripheral surface of the upper end portion of the outer container 15. Thus, the cover part 20 is rotated around the central axis O, and the extraction part 16 is removed together with the cover part 20.

このようにカバー部２０を回転させる過程において、第１、第２噛合部２０ｂ、１９ｄが互いに噛み合っているので、カバー部２０に付与した回転トルクが可動筒部１９に伝達する。このとき、内装容器１４のフランジ部１７に設けられた位置決め係合凸部１７ａと、外装容器１５の上端開口面１５ｂに形成された位置決め係合凹部１５ｃとが係合しているので、可動筒部１９に伝達した回転トルクによる固定筒部１８の前記中心軸線Ｏ回りの回転移動が規制される。   Thus, in the process of rotating the cover part 20, the first and second meshing parts 20 b and 19 d are meshed with each other, so that the rotational torque applied to the cover part 20 is transmitted to the movable cylinder part 19. At this time, the positioning engagement convex portion 17a provided on the flange portion 17 of the inner container 14 and the positioning engagement concave portion 15c formed on the upper end opening surface 15b of the outer container 15 are engaged with each other. The rotational movement around the central axis O of the fixed cylindrical portion 18 by the rotational torque transmitted to the portion 19 is restricted.

以上より、前記回転トルクによって内装容器１４において可動筒部１９のみが前記中心軸線Ｏ回りに回転させられて、固定筒部１８の内周面に形成された連通溝１８ａと可動筒部１９の貫通孔１９ｃとの連通が遮断される。
その後、案内凸部２０ｃが案内溝２１の第１溝２１ａに沿って移動するように、カバー部２０を前記中心軸線Ｏ方向の上方に引き上げ、案内凸部２０ｃを第１溝２１ａの上端に到達させて、カバー部２０を注出部１６とともに外装容器１５から取り外す。
さらにその後、内装容器１４を上方に持ち上げて、位置決め係合凸部１７ａと位置決め係合凹部１５ｃとの係合を解除するとともに、外装容器１５から取り出す。
以上より、二重容器１０が、注出部１６と内装容器１４と外装容器１５とに分解される。 As described above, only the movable cylindrical portion 19 is rotated around the central axis O in the interior container 14 by the rotational torque, and the communication groove 18 a formed on the inner peripheral surface of the fixed cylindrical portion 18 and the movable cylindrical portion 19 penetrate. Communication with the hole 19c is blocked.
Thereafter, the cover portion 20 is pulled upward in the direction of the central axis O so that the guide convex portion 20c moves along the first groove 21a of the guide groove 21, and the guide convex portion 20c reaches the upper end of the first groove 21a. Then, the cover part 20 is removed from the outer container 15 together with the extraction part 16.
Thereafter, the interior container 14 is lifted upward to release the engagement between the positioning engagement convex portion 17a and the positioning engagement concave portion 15c and take out from the exterior container 15.
As described above, the double container 10 is disassembled into the extraction part 16, the interior container 14, and the exterior container 15.

次に、このように分解された状態から、内容器１１に内容物が充填された新しい内装容器１４を組付ける方法について説明する。
まず、この内装容器１４の位置決め係合凸部１７ａを、外装容器１５の上端開口面１５ｂに形成された位置決め係合凹部１５ｃに係合した状態で、内容器１１を外装容器１５内に挿入する。これにより、外装容器１５に対する内装容器１４の前記中心軸線Ｏ回りの位置が決定されて、この内装容器１４に形成された前記第２噛合部１９ｄの外装容器１５に対する前記中心軸線Ｏ回りの位置が決定されるとともに、外装容器１５に対する固定筒部１８の前記中心軸線Ｏ回りの回転移動が規制される。 Next, a method of assembling a new interior container 14 filled with contents in the inner container 11 from the state of being disassembled in this way will be described.
First, the inner container 11 is inserted into the outer container 15 in a state where the positioning engagement convex part 17 a of the inner container 14 is engaged with the positioning engagement concave part 15 c formed on the upper end opening surface 15 b of the outer container 15. . Thereby, the position around the central axis O of the inner container 14 relative to the outer container 15 is determined, and the position around the central axis O relative to the outer container 15 of the second meshing portion 19d formed in the inner container 14 is determined. At the same time, the rotational movement of the fixed cylinder portion 18 around the central axis O with respect to the outer container 15 is restricted.

次に、このように内装容器１４を外装容器１５に内装した状態で、注出部１６に設けられたカバー部２０の案内凸部２０ｃを、外装容器１５の上端部外周面に形成された案内溝２１のうち前記上端開口面１５ｂに開口する第１溝２１ａに、前記中心軸線Ｏ方向の上方から係合する。これにより、外装容器１５に対する噛合筒部２０ａおよびカバー部２０の前記中心軸線Ｏ回りの各位置がそれぞれ決定されて、噛合筒部２０ａに形成された第１噛合部２０ｂの前記中心軸線Ｏ回りの位置が決定される。
その後、カバー部２０を下方に押込み、案内凸部２０ｃをさらに第１溝２１ａに沿って下方に移動させることにより、この第１噛合部２０ｂと内装容器１４に形成された前記第２噛合部１９ｄとを互いに噛み合わせる。 Next, in the state in which the inner container 14 is housed in the outer container 15 as described above, the guide convex portion 20c of the cover portion 20 provided in the extraction portion 16 is formed on the outer peripheral surface of the upper end portion of the outer container 15. The groove 21 is engaged with the first groove 21a opened on the upper end opening surface 15b from above in the direction of the central axis O. Thereby, each position of the meshing cylinder part 20a and the cover part 20 around the central axis O with respect to the outer container 15 is determined, and the first meshing part 20b formed in the meshing cylinder part 20a around the central axis O is determined. The position is determined.
Thereafter, the cover portion 20 is pushed downward, and the guide convex portion 20c is further moved downward along the first groove 21a, whereby the first meshing portion 20b and the second meshing portion 19d formed in the interior container 14 are moved. And mesh with each other.

そしてさらに、カバー部２０を、案内凸部２０ｃが連結溝２１ｃおよび第２溝２１ｂをこの順に沿って移動するように、前記中心軸線Ｏ回りに回転させることにより、カバー部２０内に外装容器１５の上端部外周面をねじ込んで、外装容器１５の上端部外周面をカバー部２０の内周面に嵌合させるとともに、注出部１６のシリンダ１６ｃを可動筒部１９内に挿入する。   Further, the cover part 20 is rotated around the central axis O so that the guide convex part 20c moves along the connecting groove 21c and the second groove 21b in this order. The outer peripheral surface of the upper end portion of the outer container 15 is screwed to fit the outer peripheral surface of the outer container 15 into the inner peripheral surface of the cover portion 20, and the cylinder 16 c of the extraction portion 16 is inserted into the movable cylinder portion 19.

このようにカバー部２０を外装容器１５の上端部外周面に嵌合させる過程において、前記第１、第２噛合部２０ｂ、１９ｄが噛み合っていることにより、カバー部２０に付与した前記中心軸線Ｏ回りの回転トルクが可動筒部１９に伝達する。この際、内装容器１４のフランジ部１７に設けられた位置決め係合凸部１７ａと、外装容器１５の上端開口面１５ｂに形成された位置決め係合凹部１５ｃとが係合しているので、可動筒部１９に伝達した回転トルクによる固定筒部１８の前記中心軸線Ｏ回りの回転移動が規制される。これにより、可動筒部１９を固定筒部１８に対して前記中心軸線Ｏ回りに回転させ、可動筒部１９の貫通孔１９ｃと固定筒部１８の連通溝１８ａとを連通させることにより、内容器１１の内部と注出円筒部１３の内部とを連通させた状態で、注出部１６を内装容器１４の注出円筒部１３に取り付ける。   In the process of fitting the cover portion 20 to the outer peripheral surface of the upper end portion of the outer container 15 as described above, the central axis O applied to the cover portion 20 due to the engagement of the first and second engagement portions 20b and 19d. Rotational torque is transmitted to the movable cylinder portion 19. At this time, the positioning engagement convex portion 17a provided on the flange portion 17 of the inner container 14 and the positioning engagement concave portion 15c formed on the upper end opening surface 15b of the outer container 15 are engaged with each other. The rotational movement around the central axis O of the fixed cylindrical portion 18 by the rotational torque transmitted to the portion 19 is restricted. As a result, the movable tube portion 19 is rotated around the central axis O with respect to the fixed tube portion 18, and the through hole 19 c of the movable tube portion 19 and the communication groove 18 a of the fixed tube portion 18 are communicated with each other. 11 is attached to the extraction cylindrical portion 13 of the inner container 14 in a state where the inside of the extraction cylindrical portion 13 communicates with the inside of the extraction cylindrical portion 13.

以上説明したように本実施形態に係る二重容器１０によれば、注出円筒部１３のフランジ部１７に位置決め係合凸部１７ａが設けられるとともに、外装容器１５の上端開口面１５ｂに位置決め係合凹部１５ｃが形成されているので、新しい内装容器１４に交換するに際し、注出部１６を注出円筒部１３に取り付ける前に、まず、内装容器１４を外装容器１５に内装し、その後、この状態で内容器１１の内部と注出円筒部１３の内部とを連通させながら、注出部１６を注出円筒部１３の上端開口部に取り付けることが可能になり、この交換に要する手間を低減させることができる。   As described above, according to the double container 10 according to the present embodiment, the positioning engagement convex portion 17a is provided on the flange portion 17 of the extraction cylindrical portion 13, and the positioning member is provided on the upper end opening surface 15b of the outer container 15. Since the joint recess 15c is formed, before replacing the pouring part 16 with the pouring cylindrical part 13 when replacing with a new interior container 14, the interior container 14 is first installed in the exterior container 15, and then this In this state, it is possible to attach the pouring portion 16 to the upper end opening of the pouring cylindrical portion 13 while communicating the inside of the inner container 11 and the inside of the pouring cylindrical portion 13, thereby reducing the labor required for this replacement.

By engaging with the engaging recess 15c, the position around the central axis O of the inner container 14 relative to the outer container 15 is determined, and the position around the central axis O of the second meshing part 19d relative to the outer container 15 is determined. It is determined.

以上より、案内凸部２０ｃを第１溝２１ａに沿って前記中心軸線Ｏの下方に向けて移動させたときに、第１、第２噛合部２０ｂ、１９ｄを互いに噛み合わせることが可能になる。したがって、需要者において、内装容器１４を交換するために注出部１６、内装容器１４および外装容器１５を再度組付ける際、これら１４〜１６の前記中心軸線Ｏ回りの周方向位置を互いに微調整する手間を低減させることが可能になる。   As described above, when the guide convex portion 20c is moved along the first groove 21a toward the lower side of the central axis O, the first and second engaging portions 20b and 19d can be engaged with each other. Therefore, when reassembling the pouring part 16, the inner container 14 and the outer container 15 in order to replace the inner container 14 in the consumer, the circumferential positions around the central axis O of these 14 to 16 are finely adjusted to each other.
