ABSTRACT:
A disposable valve mounted to the wall and extending within the interior of containers such as disposable air bags or bulk containers includes a valve body having a hollow interior which receives a valve plug formed with a closure plate at one end and at least one fluid flow passageway. The valve plug is moved relative to the valve body by a fluid injector tip to an open position in which a portion of one or more fluid flow passageways in the valve plug extends exteriorly of the valve body and within the interior of the container to permit the passage of fluid therethrough, and then either in or out of the container. A resilient strap or band connected between the valve body and the flange of the valve plug, together with the pressure of the fluid inside of the container, forces the valve plug to a closed position upon removal of the fluid injector tip in which the fluid flow passageways in the valve plug are positioned interiorly of the valve body and an O-ring carried on the closure plate of the valve plug forms a seal between the valve plug and an end of the valve body.
