Abstract
A self-opening blister package is provided having a packaging sleeve or carton and a formed tray. The tray includes one or more receptacle cups, which are dimensioned to receive one or more products, such as gum or the like. A peelable membrane is sealed to the tray flange. A leading edge of the membrane is attached to the sleeve. The membrane peels away from the tray when the tray is removed from the sleeve. The peeling action exposes the product contained in the one or more cups. Once the desired amount of product is extracted, the tray can be pushed back into the sleeve and the membrane rolls back over the tray.
