Description

【０００１】
【発明の属する技術分野】
本発明は、ヒンジ付蓋部を容器に装着するキャップ本体や容器の肩部に嵌着したヒンジ付蓋部を有する容器に関するものである。
【０００２】
【従来の技術】
従来、ヒンジ付蓋部を有する容器としては、キャップ本体にヒンジ付蓋部を嵌着したヒンジキャップを容器の口頸部に装着したものが一般的であり、このヒンジキャップのヒンジ付蓋部の取付構造としては、特開平７−１３７７５６号公報に本発明に類するものが開示されている。
【０００３】
このヒンジ付蓋部の取付構造は、図５に示すように、ボトル本体の口頸部に嵌合固定されるキャップ本体（２００）と、このキャップ本体の排出口を閉鎖するヒンジ付蓋部（１００）とが別体に形成され、キャップ本体にボトル本体の縦方向に延びる挿着穴（２５０）が形成され、この挿着穴にヒンジ付蓋部の板状の差込片部（１４０）を差し込んで固定するヒンジキャップ（１０）において、差込片部の下端部に縦方向に延びる係止溝（１４１）による二股に分岐する一対の係止片部（１４２，１４３）が形成され、この一対の係止片部の相対する内側の側面に互いに接近方向に突出する顎部（１４４，１４５）が形成され、挿着穴を形成する幅の広い内壁面に一対の係止片部が嵌合する嵌合部（２５１）が形成され、差込片部を挿着穴に挿入したときに、この嵌合部の下部が一対の係止片部の顎部に保持されていることを特徴とするヒンジ付蓋部の取付構造であった。
【０００４】
【発明が解決しようとする課題】
上述の特開平７−１３７７５６号公報のヒンジ付蓋部の取付構造によるヒンジキャップを装着した従来のヒンジ付蓋部を有する容器は、ヒンジ付蓋部の差込片部がキャップ本体の挿着穴の内壁面に設けられた嵌合部の下部を一対の係止片部の顎部に保持しているため、通常の容器の使用においては、蓋部がキャップ本体から抜けることはないが、しかしながら、強い外力が蓋部に加えられた場合、例えば、蓋部だけをもって容器を扱われたときなどに、特に容量の多い容器においては、蓋部がキャップ本体から抜けてしまうことがあった。また、取付構造部が広口容器などのように口部の内側にくる場合には、内容物を排出するときに、内容物が取付構造部へ侵入してしまうことがあった。
【０００５】
本発明は、上述の従来の問題を解決したものであり、強い外力に対しても蓋部が容器から離脱しにくく、蓋部の取付構造部が封止されており、しかも取付構造が比較的簡単なヒンジ付蓋部を有する容器を提供するものである。
【０００６】

A mounting structure similar to the present invention is disclosed in Japanese Patent Laid-Open No. 7-137756.
[0003]
As shown in FIG. 5, the attachment structure of the hinged lid part includes a cap body (200) fitted and fixed to the mouth / neck part of the bottle body, and a hinged lid part for closing the discharge port of the cap body ( 100) is formed separately, and an insertion hole (250) extending in the longitudinal direction of the bottle body is formed in the cap body, and a plate-like insertion piece (140) of the lid portion with a hinge is formed in the insertion hole. In the hinge cap (10) that is inserted and fixed, a pair of locking piece portions (142, 143) that are bifurcated by a locking groove (141) extending in the vertical direction is formed at the lower end portion of the insertion piece portion, Jaw portions (144, 145) projecting in the approaching direction are formed on the opposite inner side surfaces of the pair of locking pieces, and the pair of locking pieces are formed on the wide inner wall surface forming the insertion hole. A fitting part (251) to be fitted is formed, and the insertion piece part is used as an insertion hole. When you type, the lower portion of the fitting portion was mounting structure of the lid portion hinged, characterized in that it is held in the jaws of the pair of locking pieces.

A threaded portion is provided. Separately from this, a sealing plug (300) was produced by injection molding using polyethylene. This sealing plug has a concave shape composed of a peripheral wall having a side wall (311) and a side wall (312) and a bottom wall (320).
[0014]
Next, the insertion piece part (140) of the above-mentioned hinged cover part (100) is inserted and attached to the insertion hole (240) of the cap body (200), and a concave seal is formed from below the insertion hole. A cap (300) is attached to make a hinge cap (10), and this hinge cap is screwed into the mouth and neck (21) of the polyethylene container body (20) filled with the contents and inserted. A container (1) having a hinged lid part of this example was produced. The assembly operation described above was easy because of its simple structure.
[0015]
And the container which has a cover part with a hinge of a present Example, when a container is handled only with a cover part, a cover part does not detach from a container, but when contents are discharged, a content is an attachment structure part. Never invaded.
[0016]
<Example 2>
FIG. 2A is an exploded perspective view showing a configuration of a container having a hinged lid portion according to the present embodiment, and FIG. 2B is a perspective view showing an appearance thereof. Next, the present embodiment will be described in detail with reference to these drawings.
[0017]
The hinged lid (100) and the cap body (200) were produced in the same manner as in Example 1. The inner plug (400) was produced by injection molding using polyethylene, and the top plate (410 ) Is provided with an opening (420) and a sealing plug (430), and this sealing plug is a concave shape comprising a peripheral wall having a side wall (431) and a side wall (432), and a bottom wall (433). .
[0018]
Next, the insertion piece part (140) of the above-mentioned hinged cover part (100) is inserted and attached to the insertion hole (240) of the cap body (200), and a concave seal is formed from below the insertion hole. A hinge cap (10) is manufactured by attaching an inner plug (400) having a stopper portion, and this hinge cap is screwed into the mouth and neck portion (21) of the polyethylene container body (20) filled with the contents. Thus, a container (1) having a hinged lid part of this example was produced. The assembly operation described above was easy because the structure was simple as in the first embodiment.
[0019]
And the container having the hinged lid part of this embodiment does not detach from the container even if the container is handled with only the lid part, and the contents are attached when the contents are discharged. There was no intrusion into the structure.
[0020]
<Example 3>
FIG. 3 is an exploded perspective view showing a configuration of a container having a hinged lid portion of the present embodiment. Next, this embodiment will be described in detail with reference to FIG.
[0021]
First, a hinged lid (100) was produced by injection molding using polypropylene. This lid portion is a plate below the hinge portion (130) by a snap hinge comprising four hinges (131, 132, 133, 134) provided on one side of the peripheral portion and an elastic piece (135). A pair of locking pieces (142, 142) branched into two branches by forming a locking groove (141) extending in the vertical direction at the lower end of the insertion piece. 143), and jaws (144, 145) projecting in the approaching direction are formed on opposite side surfaces of the pair of locking pieces.
[0022]
Next, a shoulder member (500) was produced by injection molding using polyethylene. The shoulder member is provided with an insertion hole (540) for hanging the discharge port (530) and the back plate (541) in the top plate (510), and the back plate of the insertion hole has a pair of lid portions. A fitting portion (542) having a flange portion (543) is provided at the tip to which the locking piece portion is fitted. Next, a tubular barrel body (600) made of polyethylene was heat-sealed to the peripheral edge of the lower end of the shoulder member to produce a tubular container body (20). Separately from this, a sealing plug (300) was produced by injection molding using polyethylene. This sealing plug has a concave shape composed of a peripheral wall having a side wall (311) and a side wall (312) and a bottom wall (320).
[0023]
Next, the insertion piece part (140) of the above-mentioned hinged lid part (100) is inserted into the insertion hole (540) of the shoulder member (500) of the tube-shaped container body, and from below the insertion hole. A concave sealing plug (300) is attached and attached, and after filling the contents through the opening at the lower end of the barrel, the lower end of the barrel is heat-sealed and sealed. (1) was produced. The assembly operation described above was easy because the structure was simple as in the first embodiment.
[0024]
And the container having the hinged lid part of this embodiment does not detach from the container even if the container is handled with only the lid part, and the contents are attached when the contents are discharged. There was no intrusion into the structure.
[0025]
【The invention's effect】
In the container having the hinged lid portion of the present invention, the insertion piece portion of the lid portion is bifurcated to form a pair of locking piece portions, and this pair of locking piece portions is the back plate of the insertion hole. The jaw part is brought into contact with the lower part of the fitting part to hold the fitting, and the inner surface of the side wall of the sealing plug or the sealing plug part contacts and locks the pair of locking pieces from both sides. Therefore, there is no fear that the lid part will come off from the container even with a strong external force. Further, since the mounting structure is completely sealed, the contents do not enter the mounting structure when discharging. Moreover, the lid mounting structure is relatively simple.
