Abstract:
1. A container assembly comprising: a flexible first wall of a polymeric material, the wall defining a fluid tight chamber; a valve body attached to the first wall and having a second wall, a fluid inlet a fluid outlet and a flange having opposed first and second surfaces and a centrally disposed opening through the flange, a first cylindrical wall extends from the first surface and is disposed circumjacent the opening, the first cylindrical wall having a fluid exit through the wall and in fluid communication with the opening, the valve body having a first member for attaching the valve body to the flexible first wall of the container and a second member proximate the fluid inlet adapted to reduce the tendency for a portion of the flexible wall of the container to block the flow of fluid through the fluid inlet; a plunger associated with the valve body and moveable with respect to the valve body from a first position to a second position; and a diaphragm positioned in the valve body for movement between a third position and a fourth position when the plunger is in the first position, wherein when the diaphragm is in the third position the fluid outlet is closed and when the diaphragm is in the fourth position the fluid outlet is open, the diaphragm moves from the fourth position to the third position in response to fluid flow through the valve body in a first direction from the fluid outlet toward the fluid inlet.
