【考案の詳細な説明】 この考案は、魔法瓶などの液体容器の蓋体を下口部材に
開閉自在に枢着する蝶番部の取付構造の改良に関する。[Detailed Description of the Invention] This invention relates to an improvement in the mounting structure of a hinge part that pivots the lid of a liquid container such as a thermos flask to a lower mouth member so as to be openable and closable.

従来、この種液体容器の蝶番部は、第３図に示す如く、
外装体１′上部外周及び蓋体２′下部外周の外方に軸４
′を介して突出して設けられているのが通常である。Conventionally, the hinge part of this type of liquid container was as shown in Fig. 3.
A shaft 4 is provided outside the outer periphery of the upper part of the exterior body 1' and the outer periphery of the lower part of the lid body 2'.
Usually, it is provided so as to protrude through the hole.
