ABSTRACT:
A dispenser (10) for use in dispensing liquid or solid material. The dispenser (10) includes wall portions forming a sealed first chamber (18) containing the material and wall portions forming a second chamber (20) and a molded, rupturable membrane (34) disposed between the first chamber (18) and the second chamber (20). The rupturable membrane (34) is preferably a circular disk with a series of molded radial depressions (40) or weld seams (40) extending from a center point of the disk. When pressure is applied directly to the membrane (34), the membrane (34) is fractured along the depressions (40) or weld seams (40). A method is provided for forming the dispenser (10) by injection molding.
