Patent ID: 8272725

Claim:
A liquid container comprising: a container body to store a liquid; a pressure release mechanism to open and close a pressure release path in the container body; and a fixing member, the container body comprising: the pressure release path to connect a release path and the pressure release mechanism; a cylindrical holder mounting part having the pressure release path therein to which the pressure release mechanism is attached; multiple hooks provided at vertically opposed positions outside the cylindrical holder mounting part with the cylindrical holder mounting part interposed therebetween; and the release path formed within the container body to release pressure from the container body, the pressure release mechanism comprising: a pressure communicating part to communicate with air through a filter member; and a holder attached to the cylindrical holder mounting part, the holder comprising a pressure path to connect the pressure release path and the pressure communicating part and a valve mechanism to open and close the pressure path, the valve mechanism comprising a cylindrical valve seat to contact a valve seat holding member, a valve to contact an inner diameter of the valve seat, an elastic member to press the valve against the valve seat, and a biasing pin inserted into the pressure path, an end of the biasing pin contacting the valve, the valve seat holding member having an opening through which the pressure path passes, the valve seat holding member provided on a wall surface of the holder opposite a wall surface thereof to be attached to the cylindrical holder mounting part, the fixing member fixing the holder to the cylindrical holder mounting part by being inserted into each of a mounting portion of the holder and a mounting portion of the cylindrical holder mounting part from a horizontal direction perpendicular to the positions of the hooks while the holder including the valve mechanism is inserted into the cylindrical holder mounting part.
