Description

本開示は、キャップ付き容器に関する。 The present disclosure relates to capped containers.

従来、容器本体の口部に着脱可能なキャップとしては、ねじ部を有するものが知られている。このようなねじキャップは、通常、口部への着脱のために多くの回転操作が必要となるため、回転操作の途中で持ち替えが必要になる。したがって、操作性を考慮すると、キャップの着脱に要する回転角度を低減することが望ましい。キャップの着脱に要する回転角度は、ねじ部を例えば特許文献１に記載されるような多条ねじにして、条数を増やしていくことで低減できる。 Conventionally, as a cap that can be attached to and detached from the mouth of the container body, a cap having a screw portion is known. Since such a screw cap usually requires a lot of rotation operations for attaching and detaching to and from the mouth, it is necessary to change the holding during the rotation operation. Therefore, considering operability, it is desirable to reduce the rotation angle required for attaching and detaching the cap. The rotation angle required for attaching and detaching the cap can be reduced by increasing the number of threads by making the threaded portion a multi-threaded screw as described in Patent Document 1, for example.

特開２０１２−２３２７７３号公報Japanese Unexamined Patent Publication No. 2012-232773

しかし、多条ねじの条数を増やしていくと、キャップの着脱に要する回転角度は低減するものの、ねじ部の全高寸法が増加して、容器の全高寸法の増加を招いてしまう。 However, if the number of multi-threaded screws is increased, the rotation angle required for attaching and detaching the cap is reduced, but the total height of the threaded portion is increased, which leads to an increase in the total height of the container.

本発明の目的は、少ない角度の回転操作でキャップを口部に着脱でき、しかも、全高寸法の増加を抑制できるキャップ付き容器を提供することにある。 An object of the present invention is to provide a container with a cap that allows the cap to be attached to and detached from the mouth portion by a rotation operation at a small angle and can suppress an increase in the total height dimension.

図１に示すように、本実施形態では、係止部材７は、回り止め状態において、容器本体２の環状段部４上に位置するように構成されている。そして、キャップ３の外周面は、容器本体２の外周面と面一となっている。 As shown in FIG. 1, in the present embodiment, the locking member 7 is configured to be located on the annular step portion 4 of the container body 2 in the non-rotating state. The outer peripheral surface of the cap 3 is flush with the outer peripheral surface of the container body 2.

本実施形態に係るキャップ付き容器１によれば、次の要領でキャップ３を容器本体２に装着することができる。まず、ユーザーは、キャップ３を、容器本体２の口部２ａに被せ、回り止め部６が回り止め凹部１６に入り込む位置まで回転させる。すると、回り止め部６が回り止め凹部１６に入り込み、図４及び図２に示すように、キャップ３の係止部材７が回り止め状態になる。このとき、キャップ３は、図１及び図２に示すように、口部２ａへの抜け止め部１２の係合が解除された非ロック状態となっている。また、このとき、図３に示すように、回動部材８の第１案内面１９ａは、可動部１３の被案内片１８より口部２ａの周方向の他方ＣＤ２側に位置している。 According to the container with a cap 1 according to the present embodiment, the cap 3 can be attached to the container body 2 in the following manner. First, the user puts the cap 3 on the mouth portion 2a of the container body 2 and rotates the cap 3 to a position where the detent portion 6 enters the detent recess 16. Then, the detent portion 6 enters the detent recess 16, and as shown in FIGS. 4 and 2, the locking member 7 of the cap 3 is in the detent state. At this time, as shown in FIGS. 1 and 2, the cap 3 is in an unlocked state in which the engagement of the retaining portion 12 with the mouth portion 2a is released. At this time, as shown in FIG. 3, the first guide surface 19a of the rotating member 8 is located on the other CD2 side of the mouth portion 2a in the circumferential direction from the guided piece 18 of the movable portion 13.

この状態でユーザーが回動部材８を口部２ａの周方向の一方ＣＤ１に約３０°回転させると、図８に示すように、第１案内面１９ａは、口部２ａの周方向の一方ＣＤ１への移動に伴って被案内片１８を押圧して可動部１３を径方向内側に移動させ、図７及び図６に示すように、抜け止め部１２を口部２ａの抜け止め凹部２２に係止可能に係合させることができる。また、このようにキャップ３がロック状態となったとき、図７に示す第１係合部２７によってクリック感を生じさせ、ユーザーにキャップ３がロック状態となったことを知覚させることができる。また、このとき、図８に示すように、回動部材８のストッパ部２６は、被案内片１８の先端面に当接して、回動部材８の回転を確実に停止させることができる。このように、ユーザーは、キャップ３を係止部材７が回り止め状態になるまで回転させてから約３０°回転させるだけの回転操作によって、キャップ３を容器本体２に装着することができる。 In this state, when the user rotates the rotating member 8 about 30 ° to one CD1 in the circumferential direction of the mouth portion 2a, as shown in FIG. 8, the first guide surface 19a is the one CD1 in the circumferential direction of the mouth portion 2a. The guided piece 18 is pressed to move the movable portion 13 inward in the radial direction, and the retaining portion 12 is engaged with the retaining recess 22 of the mouth portion 2a as shown in FIGS. 7 and 6. It can be stopped and engaged. Further, when the cap 3 is locked in this way, the first engaging portion 27 shown in FIG. 7 causes a click feeling, and the user can perceive that the cap 3 is locked. Further, at this time, as shown in FIG. 8, the stopper portion 26 of the rotating member 8 can abut on the tip surface of the guided piece 18 to reliably stop the rotation of the rotating member 8. In this way, the user can attach the cap 3 to the container body 2 by rotating the cap 3 until the locking member 7 is in a non-rotating state and then rotating the cap 3 by about 30 °.

また、キャップ３を容器本体２から離脱させる要領は次のとおりである。キャップ３のロック状態では、図８に示すように、回動部材８の第２案内面１９ｂは、可動部１３の被案内片１８より口部２ａの周方向の一方ＣＤ１側に位置している。この状態でユーザーが回動部材８を口部２ａの周方向の他方ＣＤ２に約３０°回転させると、図３に示すように、第２案内面１９ｂは、口部２ａの周方向の他方ＣＤ２への移動に伴って被案内片１８を押圧して可動部１３を径方向外側に移動させ、図２及び図１に示すように、口部２ａへの抜け止め部１２の係合を解除することができる。また、このとき、可動部１３は、弾性アーム１７の復元方向の弾性力によっても径方向外側に移動するため、ユーザーによる回動部材８の回転操作を容易にすることができる。また、このようにキャップ３が非ロック状態となったとき、図２に示す第２係合部２８によってクリック感を生じさせ、ユーザーにキャップ３が非ロック状態となったことを知覚させることができる。このようにキャップ３を非ロック状態にすることで、キャップ３を口部２ａから引き上げ、離脱させることが可能となる。したがって、ユーザーは、キャップ３を約３０°回転させるだけの回転操作によって、キャップ３を容器本体２から離脱させることができる。このように、容器本体２からのキャップ３の離脱は、装着時よりもさらに少ない回転操作によって行うことができる。 The procedure for detaching the cap 3 from the container body 2 is as follows. In the locked state of the cap 3, as shown in FIG. 8, the second guide surface 19b of the rotating member 8 is located on one CD1 side of the mouth portion 2a in the circumferential direction from the guided piece 18 of the movable portion 13. .. In this state, when the user rotates the rotating member 8 to the other CD2 in the circumferential direction of the mouth portion 2a by about 30 °, the second guide surface 19b becomes the other CD2 in the circumferential direction of the mouth portion 2a as shown in FIG. The guided piece 18 is pressed to move the movable portion 13 outward in the radial direction, and the engagement of the retaining portion 12 with the mouth portion 2a is released as shown in FIGS. 2 and 1. be able to. Further, at this time, since the movable portion 13 moves radially outward due to the elastic force in the restoring direction of the elastic arm 17, it is possible to facilitate the rotation operation of the rotating member 8 by the user. Further, when the cap 3 is in the unlocked state in this way, the second engaging portion 28 shown in FIG. 2 causes a click feeling, and the user can perceive that the cap 3 is in the unlocked state. it can. By setting the cap 3 in the unlocked state in this way, the cap 3 can be pulled up from the mouth portion 2a and detached from the mouth portion 2a. Therefore, the user can separate the cap 3 from the container body 2 by a rotation operation of rotating the cap 3 by about 30 °. In this way, the cap 3 can be detached from the container body 2 with a smaller number of rotation operations than when it is attached.

このように、本実施形態に係るキャップ付き容器１は、回動部材８の案内部１９により、口部２ａの周方向の一方ＣＤ１への回動部材８の回転に伴って可動部１３を径方向内側に移動させてキャップ３をロック状態にするとともに、口部２ａの周方向の他方ＣＤ２への回動部材８の回転に伴ってキャップ３を非ロック状態にするように構成されているので、少ない角度の回転操作でキャップ３を口部２ａに着脱することができ、しかも、容器１の全高寸法の増加を抑制することができる。また、抜け止め部１２を有する係止部材７は、複雑な構造の金型を用いなくても射出成形によって得ることができる。しかも、抜け止め部１２は、金型の所謂無理抜きによって形成する必要がないため、鋭いエッジを有するものとすることができる。したがって、口部２ａへの抜け止め部１２の強い係止力を容易に得ることができる。 As described above, in the container 1 with a cap according to the present embodiment, the guide portion 19 of the rotating member 8 causes the movable portion 13 to have a diameter as the rotating member 8 rotates to one CD1 in the circumferential direction of the mouth portion 2a. Since the cap 3 is moved inward in the direction to lock the cap 3, and the cap 3 is unlocked as the rotating member 8 rotates to the other CD2 in the circumferential direction of the mouth portion 2a. The cap 3 can be attached to and detached from the mouth portion 2a by rotating the container 1 at a small angle, and the increase in the total height of the container 1 can be suppressed. Further, the locking member 7 having the retaining portion 12 can be obtained by injection molding without using a mold having a complicated structure. Moreover, since the retaining portion 12 does not need to be formed by so-called forcible removal of the mold, it can have a sharp edge. Therefore, a strong locking force of the retaining portion 12 to the mouth portion 2a can be easily obtained.

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、案内部１９は、係止部材７の回り止め状態における口部２ａの周方向の一方ＣＤ１及び他方ＣＤ２への回動部材８の回転に伴って口部２ａの径方向への可動部１３の移動を案内することにより、キャップ３の状態をロック状態と非ロック状態との間で切替えるように構成されていた。しかし、案内部１９は、係止部材７の回り止め状態における口部２ａの周方向の一方ＣＤ１のみ（又は他方ＣＤ２のみ）への回動部材８の回転に伴って口部２ａの径方向への可動部１３の移動を案内することにより、キャップ３の状態をロック状態と非ロック状態との間で切替えるように構成されてもよい。この場合、例えば、案内部１９は、係止部材７の回り止め状態における口部２ａの周方向の一方ＣＤ１への回動部材８の回転により、可動部１３を口部２ａの径方向内側へ案内してキャップ３をロック状態にするとともに、口部２ａの周方向の一方ＣＤ１への回動部材８のさらなる回転により、可動部１３を口部２ａの径方向外側へ案内してキャップ３を非ロック状態にするように構成されてもよい。 In the above-described embodiment, the guide portion 19 moves in the radial direction of the mouth portion 2a as the rotating member 8 rotates to one CD1 and the other CD2 in the circumferential direction of the mouth portion 2a in the detented state of the locking member 7. By guiding the movement of the movable portion 13 of the cap 3, the state of the cap 3 is configured to be switched between the locked state and the unlocked state. However, the guide portion 19 moves in the radial direction of the mouth portion 2a as the rotating member 8 rotates in the circumferential direction of the mouth portion 2a in the detent state of the locking member 7 only to one CD1 (or only the other CD2). By guiding the movement of the movable portion 13 of the cap 3, the state of the cap 3 may be switched between the locked state and the unlocked state. In this case, for example, the guide portion 19 moves the movable portion 13 inward in the radial direction of the mouth portion 2a by rotating the rotating member 8 to one CD1 in the circumferential direction of the mouth portion 2a in the detented state of the locking member 7. The cap 3 is guided to the locked state, and the movable portion 13 is guided outward in the radial direction of the mouth portion 2a by further rotation of the rotating member 8 to one CD1 in the circumferential direction of the mouth portion 2a to guide the cap 3.

However, the guide unit 19 is not limited to the one having the first guide surface 19a. Further, in the above-described embodiment, the guide unit 19 has a second guide surface 19b. However, the configuration may be such that the second guide surface 19b is not provided. Further, in the above-described embodiment, the movable portion 13 has a retaining auxiliary portion 20. However, the structure may be such that the retaining auxiliary portion 20 is not provided. Further, in the above-described embodiment, the rotating member 8 has a stopper portion 26.
