Description
本発明は、容器本体とこれに螺合する蓋体とからなる容器の蓋体係止構造に関し、容器本体首基部肉盛切欠部とキャップ部外周の螺子山直交方向に設けた切欠部を相当接させることで、キャップ部と一体成形した蓋体の一領域を常に容器本体の決まった一領域に対応さることを可能とし、さらに、キャップ底部中央に設けた傾斜加工が施された環状スカート部により密封性を向上させた密封容器の蓋体係止構造に関するものである。 The present invention relates to a container lid locking structure composed of a container body and a lid body screwed into the container body, and corresponds to a container body neck base built-up cutout portion and a cutout portion provided in the direction perpendicular to the thread on the outer periphery of the cap portion. By making contact with each other, it is possible to always correspond one region of the lid body integrally formed with the cap portion to a predetermined region of the container body, and further, an annular skirt portion provided with an inclined process provided at the center of the cap bottom portion. It is related with the cover body latching structure of the sealed container which improved the sealing performance.
従来、容器首部とキャップとが螺合するタイプの容器にあっては、単に雄螺子と雌螺子とを嵌合させるだけの構造を有するものが多い。さらに、安価に製造加工する目的、及び取扱いの容易さから、容器及びキャップ共々雄螺子、雌螺子が合成樹脂により成形されている。
しかしながら、上記のような容器においては、キャップの締め付けすぎ、あるいは締め付け不足は使用者の感覚に左右され、完全な螺合状態が常に得られるとは限らない。また、度重なる使用によって螺子山に摩耗を伴うことから、螺合に不具合が生じ、前述の事象は経年とともに一層顕著となる。
さらに、前述の理由から、容器本体に対して常にキャップの同じ一側面あるいは同じ領域を対応させるものとなっておらず、例えば、容器本体とキャップを一体と捉えたデザインを施そうとしても、両者の間にズレが生じることが多いことから、これまで別々にデザインが施されてきたり、キャップはデザインの対象から外されてきたりしてきた。
そこで、本発明は上記の問題点に鑑み、キャップの密封性を向上させるとともに、キャップと容器本体とを常に一定の領域で対応させ、使用者の感覚に依らずとも、完全な螺合状態を常に得ることができ、キャップの締め付け具合によるズレ、また経年の摩耗によるズレや不具合が生じない密封容器の蓋体係止構造を提供することを目的とする。2. Description of the Related Art Conventionally, many types of containers in which a container neck and a cap are screwed have a structure in which a male screw and a female screw are simply fitted. Furthermore, for the purpose of manufacturing and processing at a low cost and ease of handling, both the container and the cap are made of a male screw and a female screw made of a synthetic resin.
However, in the container as described above, over-tightening or under-tightening of the cap depends on the sense of the user, and a complete screwed state is not always obtained. In addition, since the screw thread is worn due to repeated use, a problem occurs in the screwing, and the above-described phenomenon becomes more prominent as time passes.
Furthermore, for the reasons described above, the same side surface or the same region of the cap does not always correspond to the container body. For example, even if an attempt is made to design the container body and the cap as one body, Since there is often a gap between the two, the design has been applied separately and the cap has been excluded from the design.
Therefore, in view of the above problems, the present invention improves the sealing performance of the cap, and always makes the cap and the container main body correspond to each other in a certain area, so that a completely screwed state can be obtained without depending on the sense of the user. An object of the present invention is to provide a lid locking structure for a sealed container that can be always obtained and does not cause a displacement due to a tightening condition of a cap, or a displacement or a defect due to aged wear.

The construction material is made of thermoplastic resin such as polystyrene, polyethylene, polypropylene, polyvinyl chloride, thermosetting resin such as phenol resin, and other synthetic plastics, and the lid is the container body Although it is molded more rigidly, the container body may be molded more rigidly than the lid. These moldings are performed by injection molding, hollow molding, vacuum molding, compression molding or other known molding methods. Moreover, according to the kind of content, as long as the characteristic of this application is not impaired, it is not restricted to the said material, You may use another material. Furthermore, the container body or the lid may be transparent as necessary.
As shown in FIGS. 1 and 3, the sealed container lid (2) having the sealed container lid locking structure of the present invention includes a grip section (3) having a concave cross section and a center of the grip section. It has a structure in which a cap portion (4) having an internal thread (11) on the inner periphery is integrally formed. Moreover, as shown in FIG. 2, it is good also as a structure which supports the said holding part inner wall and a cap part with a support piece (7) for reinforcement. And the notch part (6) provided in the orthogonal direction with the screw thread is formed in the said cap part surrounding wall end surface.
The container body neck (9) is provided with a male screw (10) that is screwed with the cap part female screw, and the container body neck base has a built-up part (12) having the same outer diameter as the outer periphery of the cap part. The notch (13) provided in the direction perpendicular to the screw thread is formed in the build-up part, and the notch (13) and the notch (6) are substantially in contact with each other, so that the cap part and the container body The screwing with the neck is stopped at that position.
Note that “provided in a direction orthogonal to the screw thread” means notch in a plane including an axis (P) passing through the center of the container opening as shown in FIG.
In addition to the above, as a means for stopping the progress of screwing between the lid and the container neck, it is also conceivable that the male screw and the female screw are brought into substantial contact with each other on the surface.
In other words, the opening end of the male screw is formed into a male screw with a surface perpendicular to the screw thread, and the top groove on the upper bottom portion of the female screw provided on the cap portion is formed with a surface perpendicular to the screw thread. Thus, the female screw groove is terminated, and when the screwing of the cap portion and the container main body neck portion is completed, the male screw tip surface and the female screw end surface are in substantial contact with each other.
It should be noted that “provided in a direction orthogonal to the above-described screw thread” means to cut out in a plane including an axis (P) passing through the center of the container opening as shown in FIG.
In addition, the cap base has an annular skirt portion (8) having a taper slope (14) extending toward the container opening at the inner bottom of the cap portion. When the screwing of the container and the container main body neck is completed, a force in the radially outward direction is applied to the peripheral wall of the container main body neck, and the seal is engaged. At this time, since the container main body is formed of a material softer than the lid, the distal end portion of the neck peripheral wall is slightly deformed radially outward as shown in FIG.
The shape of the container body is not limited to the shape described in the examples described later, and may be other three-dimensional shape as long as it has the characteristics of the present application.
Moreover, as shown in FIG. 7 and FIG. 8, the said recessed part (3) and a cap part (4) are comprised separately, and it comprises as a cover body (2a) and a transparent cap (4a), and a cover body (2a) is provided with a fitting hole (18) for fitting with the cap (4a), and locking means (19) (20) (for locking the lid (2a) and the container body (1)) It is good also as a structure which has the latching means which concerns on any one combination of the latching means (23) and (24) which 21 (22) or a cover body (2a) and the said cap (4a) latch.
いかに、本発明の密閉容器の蓋体係止構造の第一の実施例を第１図〜第５図を参照して説明する。
第１図は本発明の密封容器の蓋体係止構造有する容器の全体参考図、第２図は蓋体の構造を示した拡大斜視図、第３図は螺合完了した蓋体と容器首部の端面図、第４図は容器本体首部を示す一部省略斜視図である。なお、第２図中、雌螺子を、また、第４図中、雄螺子、雌螺子、把持部を省略して図示している。（１）は容器、（２）は蓋体、（３）は把持部、（４）はキャップ部、（５）は容器本体、（６）はキャップ部周壁に設けた切欠部、（７）は支持片、（８）は環状スカート部、（９）は容器本体首部、（１０）は雄螺子、（１１）は雌螺子、（１２）は肉盛部、１３は肉盛部に設けた切欠部、（１４）は環状スカート部の外側傾斜である。
本実施例における密閉容器（１）は第１図に示したように、首部（９）を有する直方体の容器本体（５）と、当該容器本体の形状と外径に合わせた蓋体（２）とから構成される。

一方、容器本体（５）の首部（９）には雄螺子（１０）が設けられ、当該容器本体の首基部には、前記キャップ部外周と同外径の肉盛部（１２）を形成するとともに、当該肉盛部に螺子山と直交方向に設けた切欠部（１３）を形成する。
本実施例における密閉容器（１）は、１辺５５ｍｍ、全長１４０ｍｍを有し、その内蓋体の高さは３０ｍｍである。
材質は容器本体（５）がポリエチレン、蓋体（２）はポリスチレンによりそれぞれ成形され、蓋体（２）は容器本体（５）より硬質である。なお、材質は本願の特徴を損なわないものであればその他の合成樹脂等を材料としても良い。
把持部（３）を手掛かりに、容器本体首部（９）の雄螺子（１０）キャップ部（４）内周に設けた雌螺子（１１）に嵌合させ、さらに螺合を進めるが、図５（ａ）から図５（ｂ）に示すように、キャップ部周壁端面の切欠部（６）が、容器本体首基部肉盛部（１２）の螺子山と直交方向に設けた切欠部（１３）と相当接した時点で螺合が完了する。
容器本体は蓋体より軟質な材料により成形しているため、第３図に示すように、容器本体首部先端の内壁が螺合を進めるとともに環状スカート部（８）に嵌合し、当該先端が環状スカート部（８）の外側傾斜（１４）に沿って半径外側方向に若干変形し、シール係合することでより一層密封性を高めることができる。
以上のことから、本発明を利用すれば、容器の密封性を高めることができるだけでなく、つまり、キャップ部周壁端面の切欠部（６）と容器本体首基部肉盛部（１２）の切欠部（１３）とが相当接した時点が螺合完了時点であることから、閉蓋操作が使用者の感覚に依らずに容易に確実となり、合成樹脂を材料とした容器であっても、永年使用に伴う螺子山の摩耗による螺合の不具合が生じることなく、また、螺合完了時に蓋体の一側面が容器本体の一側面とズレることなく常に面一に対応することから蓋体と容器本体とを一体と捉えたデザインを施すことが可能となる。
さらに、キャップ部に設けた切欠部（６）、及び容器本体首基部肉盛部に設けた切欠部（１３）の位置を、容器本体正面と決定したい側面中央部近傍に定めておけば、容器本体（５）と蓋体（２）とが別々になっていても、正面がどの側面であるか夫々一目瞭然となり、取扱いに便利である。A first embodiment of the closed container lid locking structure of the present invention will now be described with reference to FIGS.

Forming a raised portion (12), forming a notched portion (13) provided in the direction perpendicular to the thread on the built-up portion, and the notched portion (13) and the notched portion (6) are substantially in contact with each other. The screwing of the cap part and the container main body neck part is stopped at that position.
It should be noted that “provided in a direction orthogonal to the screw thread” means notch in a plane including an axis (P) passing through the center of the container opening as shown in FIG.
In addition to the above, as a means for stopping the progress of screwing between the lid and the container neck, it is also conceivable that the male screw and the female screw are brought into substantial contact with each other on the surface.
In other words, the opening end of the male screw is formed into a male screw with a surface perpendicular to the screw thread, and the top groove on the upper bottom portion of the female screw provided on the cap portion is formed with a surface perpendicular to the screw thread. Thus, the female screw groove is terminated, and when the screwing of the cap portion and the container main body neck portion is completed, the male screw tip surface and the female screw end surface are in substantial contact with each other.
Note that the provision in the direction orthogonal to the above-described screw thread means notch in a plane including an axis (P) passing through the center of the container opening as shown in FIG.
In addition, the cap base has an annular skirt portion (8) having a taper slope (14) extending toward the container opening at the inner bottom of the cap portion. When the screwing of the container and the container main body neck is completed, a force in the radially outward direction is applied to the peripheral wall of the container main body neck, and the seal is engaged. At this time, since the container main body is formed of a material softer than the lid, the distal end portion of the neck peripheral wall is slightly deformed radially outward as shown in FIG.
The shape of the container body is not limited to the shape described in the examples described later, and may be other three-dimensional shape as long as it has the characteristics of the present application.
Moreover, as shown in FIG. 7 and FIG. 8, the said recessed part (3) and a cap part (4) are comprised separately, and it comprises as a cover body (2a) and a transparent cap (4a), and a cover body (2a) is provided with a fitting hole (18) for fitting with the cap (4a), and locking means (19) (20) (for locking the lid (2a) and the container body (1)) It is good also as a structure which has the latching means which concerns on any one combination of the latching means (23) and (24) which 21 (22) or a cover body (2a) and the said cap (4a) latch.
