Peelable pouch containing a single film dosage and process of making same

Abstract

A peelable pouch for containing a single dosage product having a top layer joined to a bottom layer by a containment seal and a distributing seal formed with a stress riser separating a primary compartment from a secondary compartment. The primary compartment houses the product, sealed from the exterior environment. The secondary compartment includes a fold-over line. When the pouch is folded about the fold-over line the tear promoting surface condition permits a user to easily tear off a portion of the pouch and expose a portion of the secondary compartment. The product is accessed by peeling apart the secondary compartment, the distributing seal, and then peeling open the primary compartment. Preferred embodiments incorporate variation in the primary and secondary containment seal thicknesses.
