Liquid container, elastic member for liquid container, and recording apparatus

摘要

A liquid container usable with an ink jet recording apparatus comprises a connection opening for connecting between an inside and an outside of said container; an elastic member provided in said connection opening, wherein the inside and the outside are connected with each other by said elastic member being penetrated by a cylinderical member; and a housing for accommodating said elastic member, wherein said elastic member has a compressed region which is compressed by a wall surface of said housing when said elastic member is not penetrated by said cylinderical member. The elastic member has a non-compressed region which is not subjected to a compressive force from the wall surface of said housing when said cylinderical member does not penetrate said elastic member and which is brought into a compressed state by being pressed by the wall surface of said housing by the cylindrical member penetrating said elastic member.
