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

A liquid container for an ink jet recording apparatus, comprising:

• a connection opening connectable with an outside;
• an elastic member provided in said connection opening, said elastic member being adapted to be penetrated by a cylindrical member for fluid communication with the outside;
• said elastic member including a compressed region and a substantially non-compressed region in a state without said cylindrical member penetrated, disposed in this order in a direction of insertion of said cylindrical member, wherein said compressed region and said non-compressed region are capable of being compressed when they are penetrated by said cylindrical member,
• wherein said compressed region and said non-compressed region of said elastic member are portions of a single member, in the state without the cylindrical member penetrated.

A liquid container for an ink jet recording apparatus, comprising:

• a connection opening connectable with an outside;
• an elastic member plugged in said connection opening;
• a housing for housing said elastic member, said elastic member being adapted to be penetrated by a cylindrical member for fluid communication with the outside;
• a slit provided in said elastic member and extended from an end at which said cylindrical member is insertable in a direction of insertion of said cylindrical member,
• wherein said elastic member is compressed inwardly in said housing,
• wherein said elastic member is in the form of a dome having a protruded form on one side and a recessed form on the other side in the direction of insertion of the cylindrical member, the dome having a substantially uniform thickness, and said elastic member is provided with a column configuration portion of the recessed form side, wherein the slit is within the column configuration portion.
