IMPROVED VESSEL WITH BLADDER An improved thin-walled pressure vessel having a bladder is provided. This vessel includes a shell having an opening and a spout disposed around the opening. An improved cap normally closes this opening, secures the bladder to the shell of the vessel, and provides communication between the outside of the vessel and the inside of the bladder. The cap member comprises a main body member having an opening which receives a valve member. This valve member extends out through one end of the cap member. It also extends through the opposite end of the cap and into the bladder through an opening in the bladder. The valve member engages a portion of the bladder around the opening and clamps this portion against the main body member to secure the bladder to the cap member. As the pressure in the bladder increases, it forces the valve member further against the walls of the opening in the main body member, increasing the clamping force to firmly secure the bladder to the cap member. |
