Abstract

See full text

An easy open pouch is formed from front and back thin films by a seal formed between the films. The seal defines a product storage chamber and a dispensing cavity between the films. The seal completely surrounds the product storage chamber. An opening to the exterior of the pouch is formed in the seal in the dispensing cavity. The product storage chamber and the dispensing cavity are located adjacent to one another with a common wall located between them. The common wall is formed as a part of the seal and is frangible in response to a pressure differential between the product storage chamber and the dispensing cavity. Upon creating a pressure differential between the product storage area and the dispensing cavity the seal across the common wall delaminates to join the product storage chamber to the dispensing cavity. Product can then be dispensed from the product storage chamber through the dispensing cavity and out of the dispensing cavity opening.
