Description

本発明は、容器の口部に取付けられるキャップに関する。   The present invention relates to a cap attached to a mouth of a container.

従来、この種のキャップとしては、例えば図５，図６に示すように、容器１０１の口部１０２に取付けられるキャップ本体１０３と、ヒンジ部１０４を介してキャップ本体１０３に設けられた蓋体１０５とを有している。キャップ本体１０３と蓋体１０５とにはそれぞれ、キャップ本体側突部１０６と蓋体側突部１０７とが設けられている。蓋体１０５を閉じた状態では、蓋体側突部１０７がキャップ本体側突部１０６に係合することにより、蓋体１０５が閉位置に固定される。   Conventionally, as this type of cap, for example, as shown in FIGS. 5 and 6, a cap body 103 attached to the mouth portion 102 of the container 101, and a lid body 105 provided on the cap body 103 via the hinge portion 104. And have. The cap body 103 and the lid body 105 are respectively provided with a cap body side projection 106 and a lid body projection 107. In a state in which the lid 105 is closed, the lid 105 is fixed at the closed position by engaging the lid-side protrusion 107 with the cap body-side protrusion 106.

ヒンジ部１０４はキャップ本体１０３の径方向における一端縁部Ａに設けられている。また、キャップ本体側突部１０６と蓋体側突部１０７とは、ヒンジ部１０４を除いたヒンジ部１０４とは反対側の他端縁部Ｂに形成されている。   The hinge portion 104 is provided at one end edge A in the radial direction of the cap body 103. Further, the cap main body side protruding portion 106 and the lid body side protruding portion 107 are formed at the other end edge B on the opposite side of the hinge portion 104 except for the hinge portion 104.

キャップ本体１０３には、外側へ突出した円筒状の注出筒１０８が設けられている。また、蓋体１０５の内面には、蓋体１０５を閉じた状態で、注出筒１０８の上方先端部の内面と密接する封止リング１０９が設けられている。また、蓋体１０５の内面には位置決め用突部１１０が設けられ、キャップ本体１０３には位置決め用の縦溝１１１が形成されている。   The cap main body 103 is provided with a cylindrical extraction tube 108 protruding outward. Further, a sealing ring 109 is provided on the inner surface of the lid 105 so as to be in close contact with the inner surface of the upper tip of the dispensing tube 108 in a state where the lid 105 is closed. Further, a positioning projection 110 is provided on the inner surface of the lid 105, and a positioning vertical groove 111 is formed in the cap body 103.

これによると、蓋体１０５を閉じることにより、蓋体側突部１０７がキャップ本体側突部１０６に係合し、蓋体１０５が閉位置に固定される。この際、封止リング１０９が注出筒１０８の上方先端部の内面に密接するため、注出筒１０８の先端の注出口１０８ａと蓋体１０５との間が封止リング１０９によってシールされる。   According to this, by closing the lid 105, the lid-side protrusion 107 engages with the cap body-side protrusion 106, and the lid 105 is fixed at the closed position. At this time, since the sealing ring 109 is in close contact with the inner surface of the upper tip portion of the dispensing cylinder 108, the sealing ring 109 seals the gap between the dispensing outlet 108 a at the distal end of the dispensing cylinder 108 and the lid 105.

また、蓋体１０５は、ヒンジ部１０４の回動軸心１１２の周りに回動することによって、開閉される。蓋体１０５を閉じた状態では、位置決め用突部１１０が位置決め用の縦溝１１１に嵌まり込むことにより、蓋体１０５は、回動軸心１１２の方向において、キャップ本体１０３に対し位置決めされる。これにより、ヒンジ部１０４が捩れたり或いは切断されるのを防止することができる。   The lid 105 is opened and closed by rotating around the rotation axis 112 of the hinge portion 104. When the lid 105 is closed, the positioning projection 110 is fitted into the positioning vertical groove 111, whereby the lid 105 is positioned with respect to the cap body 103 in the direction of the rotation axis 112. . Thereby, it is possible to prevent the hinge 104 from being twisted or cut.

尚、上記のようなキャップは例えば下記特許文献１に記載されている。   The cap as described above is described in, for example, Patent Document 1 below.

特開平１０−７２０５３JP 10-72053 A

しかしながら上記の従来形式では、図５に示すように、蓋体１０５を閉じた際、蓋体側突部１０７がキャップ本体側突部１０６に係合することにより、蓋体１０５の位置がヒンジ部１０４とは反対側の方向Ｃ（すなわちヒンジ部１０４から遠ざかる方向）へ偏り、ヒンジ部１０４に近い側Ｅにおいて、封止リング１０９の外周面が十分な押圧力で注出筒１０８の先端部内周面に当接しなかったり或いは封止リング１０９の外周面と注出筒１０８の先端部内周面との間に隙間が発生し、容器１０１内の液体が封止リング１０９の外周面と注出筒１０８の先端部内周面との間から外部へ漏出する虞がある。   However, in the above conventional type, as shown in FIG. 5, when the lid 105 is closed, the lid-side protrusion 107 engages with the cap body-side protrusion 106, so that the position of the lid 105 is the hinge portion 104. The side of the sealing ring 109 is biased in the direction C opposite to the direction C (ie, the direction away from the hinge 104), and the outer peripheral surface of the sealing ring 109 has sufficient pressing force on the side E close to the hinge 104. Or a gap is generated between the outer peripheral surface of the sealing ring 109 and the inner peripheral surface of the tip end portion of the dispensing tube 108, so that the liquid in the container 101 can be removed from the outer peripheral surface of the sealing ring 109 and the dispensing tube 108. There is a risk of leakage to the outside from between the inner peripheral surface of the tip portion.

本発明は、蓋体を閉じた状態で、容器内の内容物が外部に漏出するのを防止することが可能なキャップを提供することを目的とする。   An object of this invention is to provide the cap which can prevent the content in a container leaking outside in the state which closed the cover body.

上記目的を達成するために、本第１発明は、容器の口部に取付けられるキャップ本体と、ヒンジ部を介してキャップ本体に設けられた蓋体とを有し、
蓋体を閉じた状態で、蓋体の係合部がキャップ本体の係合部に係合するキャップであって、
ヒンジ部はキャップ本体の径方向における一端縁部に設けられ、
キャップ本体の係合部は、ヒンジ部を除いたヒンジ部とは反対側の他端縁部に形成され、
キャップ本体に、突出した注出筒が設けられ、
注出筒は先端部に注出口を有し、
蓋体の内側に、注出口を開閉する中栓を保持する保持筒が設けられ、
中栓は、保持筒内に保持されており、蓋体を閉じた状態で注出筒内に嵌まり込む封止部を有し、
封止部の外周が注出筒の内周に当接することにより、注出口が中栓で閉じられ、
注出筒と保持筒との少なくともいずれかに、位置矯正部材がヒンジ部に近い側に位置して設けられ、
蓋体が閉じられた際、位置矯正部材は、保持筒の内周又は注出筒の外周に当接して、保持筒をヒンジ部の側へ向けて押し返すものである。 In order to achieve the above object, the first invention has a cap body attached to the mouth of the container, and a lid provided on the cap body via a hinge part,

When the lid is closed, the position correction member abuts on the inner periphery of the holding cylinder and pushes the holding cylinder back toward the hinge portion.

これによると、蓋体を閉じた際、位置矯正部材が保持筒の内側に当接して保持筒をヒンジ部の側へ押し返すため、蓋体の位置がヒンジ部とは反対側の方向（すなわちヒンジ部から遠ざかる方向）へ偏ってしまうのを防止することができる。   According to this, when the lid is closed, the position correcting member abuts on the inside of the holding cylinder and pushes the holding cylinder back toward the hinge part. Therefore, the position of the lid is opposite to the hinge part (that is, the hinge). Can be prevented from being biased in a direction away from the portion.

本第３発明におけるキャップは、注出筒は、キャップ本体の中心に対して、ヒンジ部から遠ざかる位置に偏心しているものである。
本第４発明におけるキャップは、キャップ本体の係合部は、キャップ本体の周縁部に沿って、平面視において半円弧状に形成されており、
径方向において、キャップ本体の係合部とヒンジ部との間に注出筒が位置するものである。 In the cap according to the third aspect of the present invention, the dispensing cylinder is eccentric to a position away from the hinge portion with respect to the center of the cap body.
In the cap according to the fourth invention, the engaging portion of the cap body is formed in a semicircular arc shape in plan view along the peripheral edge of the cap body.
In the radial direction, the extraction tube is positioned between the engaging portion of the cap body and the hinge portion.
