Title: BUBBLE VALVE WITH STOPPER FOR FLEXIBLE POUCH PACKAGING
Abstract:
The bubble valve contains air, gas or other fluid within flexible packaging, wherein the user can press the bubble to actuate the zipper or reclosure to open the package. The bubble valve includes a fluid containment chamber with a fluid reservoir portion with a tortuous fluid communication path with a closure portion, When the air, gas or other fluid inflates the closure portion while the fluid reservoir portion is deflated, the valve is in a closed position. When the air, gas or other fluid inflates the fluid reservoir portion and the closure portion is deflated, the valve is open and package contents can travel past the deflated closure portion,
