Abstract
A dual port dispenser button system with an elastic receptacle button having a first latch receiver and a second latch receiver, and a dispenser with a dispensing valve and vent valve. The dispensing valve includes a valve seal member and first button latch. The vent valve includes an elastomer deflection part and flexible connector. The button has a first and second depressed position. In the first depressed position, the dispensing valve seal member moves from a first position where it seals the dispensing port to a second position where it does not seal the dispensing port while the deflection part remains in a first position where it seals a vent port. In the second depressed position, the valve seal member moves to a third position that does not seal the dispensing port and the deflection part moves to a second position where it does not seal the vent port.
