More Information
Summary:A lid assembly includes a closure member and a valve assembly. The closure member has a socket in fluid communication with a liquid passageway. The socket has a wall with a cutout therein. The valve assembly includes a plug adapted for insertion into the socket to form a seal between the socket and the plug. The plug has a base, a side wall, and an interior chamber cooperatively defined by the base and the side wall. A portion of the side wall of the plug with a minimum thickness is disposed adjacent the cutout when the plug is inserted into the socket. The seal formed between the plug and socket is selectively moveable from a sealed configuration to an unsealed configuration by vacuum pressure being applied to the interior chamber of the plug.
