Description
本考案は瓶蓋の密封構造に関し、より詳細には漏れを防止して密封効果を強化する瓶蓋の密封構造に関するものである。 The present invention relates to a bottle lid sealing structure, and more particularly to a bottle lid sealing structure that prevents leakage and enhances the sealing effect.
瓶蓋の多重密封構造の公知技術に関しては、特許文献1の中華民国実用新案公告第586511号、特許文献2の日本特開第2000−191019号、特許文献3の日本特許第4634598号等において開示されている通りである。
As for the known technology of the multiple sealing structure of the bottle lid, it is disclosed in Patent Document 1, Chinese Utility Model Publication No. 586511, Japanese Patent Laid-Open No. 2000-191019 in
前記特許文献1(第586511号)及び特許文献3(第4634598号)では、瓶蓋の内側面の下方向に緊密環状体及び下圧漏れ防止環状体を突設していて、蓋体を容器の瓶口に回転させて被嵌した時に、下圧漏れ防止環状体が瓶口の上部を圧して押さえ、緊密環状体が瓶口の外側縁と密着することにより、漏れ防止効果を発揮する。前述した二つの緊密環状体構造にあっては何れにも、それが生じさせる充分な変形量を許容する長さと形状を備えるが、形状変化の応力が緊密環状体と瓶蓋内の上面の連接箇所に発生し易く、さらに冷熱の温度変化の影響を受けた該緊密環状体が亀裂を生じて脱落する慮もある。 In Patent Document 1 (No. 586511) and Patent Document 3 (No. 4634598), a tight annular body and a lower pressure leakage preventing annular body are projected downward from the inner surface of the bottle lid, and the lid body is a container. The lower pressure leak-proof annular body presses and holds the upper part of the bottle mouth and the tight annular body comes into close contact with the outer edge of the bottle mouth, thereby exhibiting a leak-preventing effect. Each of the two close ring structures described above has a length and a shape that allow a sufficient amount of deformation to be generated, but the stress of the shape change causes the connection between the close ring and the upper surface in the bottle lid. There is also a possibility that the tight annular body, which is easily generated at a location and affected by the temperature change of the cold heat, cracks and falls off.
特許文献2(第2000−191019号)では、瓶蓋の内側面の下方向に下圧漏れ防止環状体を突設していて、それと上述の下圧漏れ防止環状体の機能は同様であるが、下圧漏れ防止環状体の密封漏れ防止効果は上述した二つの特許と比べ明らかに劣るものである。 In Patent Document 2 (No. 2000-191019), a lower pressure leakage preventing annular body is provided to project downward from the inner surface of the bottle lid, and the function of the lower pressure leakage preventing annular body is the same as that described above. The sealing leakage prevention effect of the lower pressure leakage prevention annular body is clearly inferior to the above-mentioned two patents.
本考案は、公知技術の漏れ防止密封構造が内包する、容易に形状変化及び亀裂による脱落に起因した密封漏れ防止効果の消失問題を解決するためになされたもので、これらの問題を解決した新密封構造を提供することを目的とする。 The present invention was made to solve the problem of disappearance of the sealing leak prevention effect due to the drop in shape due to the shape change and cracking included in the leak prevention sealing structure of the known technology. An object is to provide a sealing structure.
本考案に係る瓶蓋の密封構造は、瓶蓋の内側環状体と側壁間に設ける環状物であり、該密封構造の断面形状は不等辺三角形とし、第一辺と第二辺の交じり合う箇所に円弧角を形成する。該第一辺の長さは第二辺を超え、第一辺と瓶蓋内側上面の交じり合う角度は90度以上とし、第二辺と瓶蓋内側上面の交じり合う角度は90度以下とする。 The sealing structure of the bottle lid according to the present invention is an annular object provided between the inner annular body and the side wall of the bottle lid, and the cross-sectional shape of the sealing structure is an unequal triangular shape, where the first side and the second side intersect An arc angle is formed in The length of the first side exceeds the second side, the angle at which the first side and the inner upper surface of the bottle lid intersect is 90 degrees or more, and the angle at which the second side and the inner upper surface of the bottle lid intersect is 90 degrees or less. .
本考案の瓶蓋の密封構造において、瓶口と瓶蓋を結合した時に、該密封構造は形状変化を起こさずに該瓶口の上面外側角を緊密に圧迫する。
また、構造強度を前述した公知技術での緊密環状体と比較すると、本考案の密封構造の方が良好である。
本考案の密封構造は、熱膨張冷縮を受け止める効果を備えるため、応力集中による裂罅問題を防ぐことができる。
さらに、本考案の密封構造は構造強度及び安定性を備え、密封構造の漏れ防止効果を強化し、その持続性を確実に保つことができる。
In the bottle lid sealing structure of the present invention, when the bottle mouth and the bottle lid are coupled, the sealing structure tightly presses the upper outer corner of the bottle mouth without causing a shape change.
In addition, the sealing structure of the present invention is better when the structural strength is compared with the close annular body in the known technique described above.
Since the sealing structure of the present invention has an effect of catching thermal expansion and contraction, it can prevent a cracking problem due to stress concentration.
Furthermore, the sealing structure of the present invention has structural strength and stability, can enhance the leakage prevention effect of the sealing structure, and can reliably maintain its sustainability.
以下図面を参照しながら本考案の実施例について説明する。 Embodiments of the present invention will be described below with reference to the drawings.
図1、図2、図3に示すとおり、本考案の密封構造30は、瓶蓋2の内側環状体10と該瓶蓋2の側壁11間に設置し、瓶蓋内側上面3から下向きに突出する環状物である。
