Description

本発明は、除去可能な栓体を有する中栓を備える抜栓キャップに関し、特に中栓にねじキャップを打栓して装着することができる抜栓キャップに関するものである。 The present invention relates to a plug-out cap provided with an inner plug having a removable plug body, and more particularly to a plug-out cap that can be attached by tapping a screw cap to the inner plug.

ドレッシングなどの内容物を収容する食品容器として、開封時まで除去可能な栓体を有する中栓により容器本体内を密封状態にし、中栓に螺合して装着されたねじキャップを螺脱方向に回動することによって中栓の栓体を開栓することができる抜栓キャップは、従来から知られている。
また、ねじキャップを中栓に螺合する際に、中心位置がずれることで、栓体に不具合が生じてしまうという問題があるため、ねじキャップに中足部を設けることで注出筒が案内されて位置合わせが容易になり、セット性が改善された抜栓キャップも知られている（特許文献１参照）。 As a food container for storing contents such as dressings, the inside of the container is sealed with an inner stopper that has a stopper that can be removed until the time of opening, and the screw cap attached by screwing to the inner stopper is screwed out. A plug removal cap that can open the plug body of the inner plug by rotating has been conventionally known.
In addition, when the screw cap is screwed into the inner plug, the center position shifts, which causes a problem in the plug body. Therefore, the injection cylinder is guided by providing the middle foot part on the screw cap. There is also known an unplugging cap that facilitates alignment and has improved settability (see Patent Document 1).

次に、本実施例の使用態様と作用効果について説明する。
本実施例の抜栓キャップを容器本体Ａに装着するには、まず、中栓Ｂの上部から中間部材Ｃを装着し、中栓Ｂと中間部材Ｃとをセットしたものを、容器本体Ａの口部１に中栓Ｂの装着部４を当てがって打栓し、最後にねじキャップＤを中間部材Ｃの上部から打栓により中栓Ｂに装着する。 Next, the usage mode and the action and effect of this example will be described.
In order to attach the unplugging cap of this embodiment to the container body A, first, the intermediate member C is attached from the upper part of the inner plug B, and the inner plug B and the intermediate member C are set, and then the mouth of the container body A is attached. The mounting portion 4 of the inner plug B is applied to the portion 1 to be plugged, and finally, the screw cap D is mounted to the inner plug B by tapping from the upper part of the intermediate member C.

中栓Ｂの上部から中間部材Ｃをセットする際には、中間部材Ｃの側壁４１内に中栓Ｂの注出筒１０がおさまっていることを確認しながら、中間部材Ｃの中心部分の係着部４２を栓体１５の筒状壁１６の上面に載置し、中間部材Ｃをわずかに回転をかけ、切断筒部４３の内歯５１を、栓体１５の外歯１８の間に嵌入させ、栓体１５の外歯１８と噛み合わせるように押し込んでいく。 When setting the intermediate member C from the upper part of the inner plug B, the central portion of the intermediate member C is engaged while confirming that the injection cylinder 10 of the inner plug B is contained in the side wall 41 of the intermediate member C. The attachment portion 42 is placed on the upper surface of the tubular wall 16 of the plug body 15, the intermediate member C is slightly rotated, and the internal teeth 51 of the cutting tubular portion 43 are fitted between the external teeth 18 of the plug body 15. Then, push it in so as to mesh with the external teeth 18 of the plug body 15.

さらに、中間部材Ｃの側壁４１に注出筒１０が案内されながら、中間部材Ｃが下降していくと、中間部材Ｃの係着部４２の第２係合突部４８が栓体１５の第１係合突部１９を乗り越えて、筒状壁１６の内周面に嵌合するようになる。
それと同時に、中間部材Ｃの側壁４１の下端部の突条部４７が中栓Ｂの係止突部２６に係合し、中間部材Ｃの中栓Ｂとのセットが完了する。
中栓Ｂへの中間部材Ｃのセットは、ねじキャップＤに比べて小さいため、中心位置が見つけやすく、また、側壁４１によって、セットがしやすくなっており、セットの際に、薄肉弱化部１４が破断してしまうようなことがない。 Further, as the intermediate member C descends while the dispensing cylinder 10 is guided to the side wall 41 of the intermediate member C, the second engaging protrusion 48 of the engaging portion 42 of the intermediate member C becomes the second of the plug body 15. 1 It gets over the engaging protrusion 19 and fits into the inner peripheral surface of the tubular wall 16.
At the same time, the protrusion 47 at the lower end of the side wall 41 of the intermediate member C engages with the locking protrusion 26 of the inner plug B, and the setting with the inner plug B of the intermediate member C is completed.
Since the setting of the intermediate member C on the inner plug B is smaller than that of the screw cap D, the center position can be easily found, and the side wall 41 makes it easy to set. Will not break.

中間部材Ｃと中栓Ｂとがセットされた後、内容物が充填された容器本体Ａの口部１に、中栓Ｂの装着部４を当てがって打栓される。
その後、ねじキャップＤを中栓Ｂに打栓によって装着する。
ねじキャップＤの装着は、中栓Ｂにセットされた中間部材Ｃの上面に、ねじキャップＤを載置し、ねじキャップＤをわずかに回転させながら押し込んでいくと、図５に示すように、ねじキャップＤのねじ筒部６２の雌ねじ６５の下端部が中栓Ｂの雄ねじ２３の上端部に当接するとともに、中間部材Ｃの係合部５４の嵌合外歯５５に、ねじキャップＤの嵌合部６４の嵌合係止部６７が乗り越え、嵌合内歯６６が噛み合いながら嵌入をはじめる。 After the intermediate member C and the inner plug B are set, the mounting portion 4 of the inner plug B is applied to the mouth portion 1 of the container body A filled with the contents to be plugged.
After that, the screw cap D is attached to the inner plug B by tapping.
To attach the screw cap D, place the screw cap D on the upper surface of the intermediate member C set in the inner plug B, and push the screw cap D while slightly rotating it. As shown in FIG. The lower end of the female screw 65 of the screw cylinder portion 62 of the screw cap D abuts on the upper end of the male screw 23 of the inner plug B, and the screw cap D is fitted to the fitting outer tooth 55 of the engaging portion 54 of the intermediate member C. The fitting locking portion 67 of the fitting portion 64 gets over, and the fitting inner teeth 66 start fitting while meshing with each other.

この状態から、ねじキャップＤを中栓Ｂに押し込むと、ねじキャップＤの雌ねじ６５は、傾斜下面６５ｂが雄ねじ２３の傾斜上面２３ａに摺接しながら雄ねじ２３を乗り越えて、ねじキャップＤのねじ筒部６２は、中栓Ｂのねじ壁部８に嵌合するようになる。
同時に、中間部材Ｃの係合部５４の嵌合外歯５５とねじキャップＤの嵌合部６４の嵌合内歯６６と噛み合いが進み、係合部５４の係合端部５６が嵌合部６４の嵌合係止部６７に係合して中間部材ＣとねじキャップＤとの嵌合も終了する。
さらに、ねじ筒部６２の下部のくさび状凹部６８が中栓Ｂのストッパー２８に当接面同士が当接して嵌合する。 When the screw cap D is pushed into the inner plug B from this state, the female screw 65 of the screw cap D gets over the male screw 23 while the inclined lower surface 65b is in sliding contact with the inclined upper surface 23a of the male screw 23, and the screw cylinder portion of the screw cap D. 62 is fitted to the screw wall portion 8 of the inner plug B.
At the same time, meshing progresses with the fitting outer teeth 55 of the engaging portion 54 of the intermediate member C and the fitting inner teeth 66 of the fitting portion 64 of the screw cap D, and the engaging end portion 56 of the engaging portion 54 is the fitting portion. Engaging with the fitting locking portion 67 of 64, fitting of the intermediate member C and the screw cap D is also completed.
Further, the wedge-shaped recess 68 at the lower part of the screw cylinder portion 62 is fitted with the stopper 28 of the inner plug B in contact with the contact surfaces.

次に、本実施例の抜栓キャップが装着された容器を使用するには、ねじキャップＤを中栓Ｂに対して螺脱方向に回転させる。
ねじキャップＤを回転すると、ねじキャップＤに嵌合する中間部材Ｃの切断筒部４３の内歯５１が回動して、その第２係合面５２が中栓Ｂの栓体１５の外歯１８の第１係合面２０に当接するようになり、ねじキャップＤの回転力が両歯を介して栓体１５に加わるようになる。
なお、本実施例では、第１係合面２０および第２係合面５２は、傾斜が形成されているが、第１係合面２０および第２係合面５２は、傾斜はなくてもよく、ねじキャップＤを回転させたときに、外歯１８と内歯５１が噛み合うことができれば問題ない。 Next, in order to use the container to which the unplugging cap of this embodiment is attached, the screw cap D is rotated with respect to the inner plug B in the screwing direction.
When the screw cap D is rotated, the internal teeth 51 of the cutting cylinder portion 43 of the intermediate member C fitted to the screw cap D are rotated, and the second engaging surface 52 thereof is the external teeth of the plug body 15 of the inner plug B. It comes into contact with the first engaging surface 20 of 18, and the rotational force of the screw cap D is applied to the plug 15 via both teeth.
In this embodiment, the first engaging surface 20 and the second engaging surface 52 are inclined, but the first engaging surface 20 and the second engaging surface 52 are not inclined. Well, there is no problem if the external teeth 18 and the internal teeth 51 can be engaged with each other when the screw cap D is rotated.

このとき、中間部材Ｃの係着部４２の第２係合突部４８が栓体１５の筒状壁１６の内周面に緊密に嵌合しているので、筒状壁１６を内側から補強してねじキャップＤの回転力が内歯５１および外歯１８を介して栓体１５に伝わりやすくなるとともに、両ねじの回転に伴って栓体１５を上方に引き上げる力を発生させる。
ねじキャップＤの回転が進むと、栓体１５に加わる回転力と引き上げ力により、ついには薄肉弱化部１４が破断して注出筒１０内に注出口が開栓され、注出筒１０から分離された栓体１５は、筒状壁１６に係合する係着部４２によって引き上げられ、中間部材ＣとねじキャップＤとともに上昇していく。 At this time, since the second engaging protrusion 48 of the engaging portion 42 of the intermediate member C is tightly fitted to the inner peripheral surface of the tubular wall 16 of the plug body 15, the tubular wall 16 is reinforced from the inside. Then, the rotational force of the screw cap D is easily transmitted to the plug body 15 via the internal teeth 51 and the external teeth 18, and a force for pulling up the plug body 15 upward is generated with the rotation of both screws.
As the rotation of the screw cap D progresses, the thinning weakening portion 14 finally breaks due to the rotational force and the pulling force applied to the plug body 15, and the spout is opened in the pouring cylinder 10 and separated from the pouring cylinder 10. The stopper body 15 is pulled up by the engaging portion 42 engaged with the tubular wall 16, and rises together with the intermediate member C and the screw cap D.

さらに、雌ねじ６５が雄ねじ２３から螺脱して、ねじキャップＤを中栓Ｂから離脱させれば、ねじキャップＤとともに栓体１５が除去された注出筒１０の開口から容器本体Ａ内の内容物を注出することができる。なお、離脱した際、中栓ＢはねじキャップＤ側に移行して保持された状態のままとなっている。 Further, when the female screw 65 is screwed off from the male screw 23 and the screw cap D is separated from the inner plug B, the contents in the container body A are opened through the opening of the dispensing cylinder 10 from which the plug body 15 is removed together with the screw cap D. Can be poured out. When the inner plug B is detached, the inner plug B is moved to the screw cap D side and remains in a held state.

内容物を注出した後、再度、ねじキャップＤを中栓Ｂに螺合する際には、中間部材Ｃの切断筒部４３の密封筒５０が注出筒１０の内周に密着して容器本体Ａ内を密封することができる。
両ねじの螺合が完了する際には、音出し部材６９の振動片７０が音出し突部３１に当接して振動し、音が発せられるので、本発明の利用者は、感覚的にねじキャップＤの閉蓋終了を知ることができる。 After pouring out the contents, when the screw cap D is screwed into the inner plug B again, the sealed cylinder 50 of the cutting cylinder portion 43 of the intermediate member C is in close contact with the inner circumference of the pouring cylinder 10 to form a container. The inside of the main body A can be sealed.
When the screwing of both screws is completed, the vibrating piece 70 of the sound producing member 69 abuts on the sound producing protrusion 31 and vibrates, and a sound is emitted. Therefore, the user of the present invention feels the screw. It is possible to know the end of closing the cap D.

本実施例の抜栓キャップの中栓Ｂは、容器を使用した後に廃棄する際に、分別機構３０を利用して容器本体Ａから分離し、分別して廃棄することができる。
把持部を手前に引っ張って縦切断部を破断し、破断はさらに周方向切断部と続き、外筒５と一体の終端の連結部で、中栓Ｂは容器本体Ａから離脱されて分別廃棄することができる。
分別機構３０は、どのようなものでもよく、なくても構わない。 When the inner plug B of the unplugging cap of this embodiment is discarded after the container is used, it can be separated from the container main body A by using the sorting mechanism 30 and sorted and discarded.
The grip portion is pulled toward you to break the vertical cut portion, and the break continues to the circumferential cut portion. At the connecting portion at the end integrated with the outer cylinder 5, the inner plug B is separated from the container body A and separately discarded. be able to.
The sorting mechanism 30 may or may not be any.

本実施例では、閉蓋終了後の回転を止めるために、中栓ＢおよびねじキャップＤにストッパー２８およびくさび状凹部６８を設けているが、閉蓋終了時に、音出し部材６９により音が発せられ、利用者は感覚的にキャップの閉蓋終了を知ることができるので、ストッパー２８およびくさび状凹部６８を設けなくても構わないし、さらに、音出し突部３１と音出し部材６９による音出し機構を設けなくてもよい。 In this embodiment, a stopper 28 and a wedge-shaped recess 68 are provided in the inner plug B and the screw cap D in order to stop the rotation after the closing of the lid. Since the user can intuitively know the end of closing the cap, it is not necessary to provide the stopper 28 and the wedge-shaped recess 68, and further, the sound output by the sound output protrusion 31 and the sound output member 69 is produced. It is not necessary to provide a mechanism.

次に、第１実施例のねじキャップＤの構成を変更した第２実施例について、図８を参照して説明する。
