Abstract:
The present invention is embodied in an apparatus, such as a blister pack, having the capability to safely store and protect items such as medication in solid, soft or semi-solid, powder, or liquid form, while allowing such items to be easily and rapidly dispensed by a user. The dispenser of the present invention has a flexible upper membrane forming a dome. A lower membrane serves to seal items between the dispensers upper and lower membranes. An annular-shaped internal cutter resides within the dome between the upper and lower membranes, oriented perpendicular to the membranes. Items are sealed within the chamber created by the structure of the cutter and the upper and lower membranes. The lower membrane is of sufficient strength to prevent inadvertent tearing or rupturing of the membrane, even when carried in a relatively hostile environment, such as with metal keys in a users pocket. However, the internal cutter is capable of cutting through this membrane by simply depressing the dome thereby providing an open path for rapid and complete evacuation of the chamber contents.
