【考案の詳細な説明】
本考案は液体等を収容する容器、特に瓶等の口
部構造に関し、特にスクリユーキヤツプを密封装
着する容器の外破防止の安全口部構造に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a mouth structure for a container containing a liquid, particularly a bottle, and more particularly to a safety mouth structure for preventing extrusion of a container to which a screw cap is hermetically attached.
従来のスクリユーキヤツプは第１図に示すよう

の螺子部を密封嵌合させて密封を行なうようにな
つており、王冠等を用いる他の構造と異なつて開
栓した後でも閉栓密封が可能であり、また使用後
の瓶を反復使用できるという利点がある。 As shown in Figure 1, conventional screw-on caps are sealed by fitting the threaded part of the cap into a threaded part formed on the mouth of the container or bottle. Unlike the structure, it is possible to close and seal the bottle even after opening, and the bottle has the advantage of being able to be used repeatedly after use.

態になることが考えられる。 However, when the internal pressure of the container or bottle increases after the cap is attached, such as with carbonated beverages, the cap expands and deforms as shown in Figure 3, creating a risk of bursting depending on the strength of the bottle material. There is also a risk. Furthermore, it is conceivable that the contents of a bottle of a non-carbonated fruit juice drink, etc., may ferment and become in a similar state after the bottle is closed.
このような欠点を除去するためには理輪的には
容器又は瓶間口部の外周縁に第４図に示すような
切り込みを部分的に設け内圧上昇時に瓶内の気体
をこの切り込みを通して排気し、異常な容器又は
瓶の内圧上昇を防止することができる。 In order to eliminate such defects, it is a good idea to partially cut a cut in the outer periphery of the container or bottle opening as shown in Figure 4, and exhaust the gas inside the bottle through the cut when the internal pressure rises. , it is possible to prevent an abnormal increase in the internal pressure of the container or bottle.
本考案の目的は上記の如くスクリユーキヤツプ
を容器口又は瓶口に密閉装着する場合容器又は瓶
内の異常な内圧の上昇を防止して不測の外破を防

口部構造を提供することにある。 As mentioned above, the purpose of the present invention is to prevent an abnormal increase in internal pressure inside the container or bottle when the screw cap is tightly attached to the mouth of a container or bottle, thereby preventing unexpected breakage, and to be suitable for mass production. The object of the present invention is to provide a mouth structure for a container or bottle.
以下本考案の実施例を図面に沿つて説明する。
第４図に示す如く、ここに示す瓶開口部の外周縁
５の適宜の場所に、瓶内の圧力気体を排気できる
１つ又はそれ以上の切り込み３を瓶のキヤツプと

第６図に示す如く切り込みを通つて排気される。 Embodiments of the present invention will be described below with reference to the drawings.
As shown in Figure 4, one or more incisions 3 are made at suitable locations on the outer periphery 5 of the bottle opening shown here, up to the apex of contact between the bottle cap and the bottle, through which the pressurized gas within the bottle can be evacuated. Set up so that it does not reach.
When the internal pressure of the bottle increases, the cap 1 is lifted, creating a space between it and the bottle opening 2, and the gas inside the bottle is exhausted through the notch as shown in FIG.
尚、瓶材料については、ガラス瓶に限らず金

できる。 Note that the material for the bottle is not limited to glass bottles, but a wide variety of other materials such as metal, ceramic, ceramic, and plastic can be used. In particular, the bottle mouth structure of the present invention can be suitably used for materials such as polyethylene terephthalate, which do not burst like glass, but which undergo plastic deformation due to excessive internal pressure and become unusable.

状態となるので、その際本考案の瓶口構造を採用
すればその圧力を逃がすことにより充分な密封が
得られる。 Furthermore, when producing bottle crystals, if the content is filled at room temperature, capped, and heat sterilized after sealing, the content becomes pressurized due to the expansion of the content and the expansion of the air at the top. If the bottle opening structure is adopted, sufficient sealing can be achieved by releasing the pressure.
本考案は、以上のような構成を有するので、液

工程に適し著しい外破防止効果を生ずる。 Since the present invention has the above-mentioned configuration, it is suitable for sealing screw caps of liquids and other bottles that are subject to changes in internal or external pressure, and is suitable for mass production of bottles and has a remarkable effect of preventing exploding.
