Claim:
1. A heat-sealed squeezable dispensing pouch comprising: an outer sheet having a front wall, a rear wall and a folded edge located between the front wall and the rear wall, wherein the outer sheet is folded along the folded edge such that an inner surface of the front wall faces an inner surface of the rear wall; a first heat seal coupling the inner surface of a peripheral section of the front wall to a peripheral section of the inner surface of the rear wall such that the inner surfaces of the front and rear walls define an interior chamber; a rupturable inner membrane formed from a contiguous, single monolayer of thermoplastic material, the rupturable inner membrane located within the interior chamber, wherein the rupturable inner membrane divides the interior chamber into a contents compartment and a dispensing channel, wherein the first heat seal defines an edge of the contents compartment and the folded edge defines an edge of the dispensing channel; a second heat seal coupling the rupturable inner membrane to the inner surface of the front wall; a third heat seal coupling the rupturable inner membrane to the inner surface of the rear wall; and a score line formed in both the front and rear walls, between the folded edge and the rupturable inner membrane, the score line configured such that the portion of the outer sheet between the score line and the folded edge can be removed to create a dispensing opening in the dispensing channel; wherein the second heat seal and the third heat seal are located within the contents compartment; wherein the rupturable inner membrane is configured to break when the pressure within the contents compartment is greater than a rupture threshold, wherein the first, second and third heat seals are configured to remain sealed when the inner membrane breaks.
