Peelable pouch containing a single or multiple dosage forms and process of making same
View Patent ↗A peelable pouch 50 for containing a single dosage product P having a top layer 100 joined to a bottom layer 200 by at least one seal 500 thereby creating a primary compartment 300 . The primary compartment 300 houses the product P, sealed from the exterior environment. The peelable pouch 50 includes a tear promoting surface condition 600 on the top layer 100 and the bottom layer 200 intersected by a fold-over line 700 . When the pouch 50 is folded about the fold-over line 700 the tear promoting surface condition 600 permits a user to easily tear off a portion of the pouch 50 and expose a portion of the primary compartment 300 allowing the product P to be removed from the pouch 50 . Alternative embodiments incorporate a product retention edge 350 that requires supplemental separation of the top 100 and bottom 200 layers to gain access to the product P, as well as a secondary compartment 400 formed between the top 100 and bottom 200 layers.
