Valve

Abstract:

A valve (100, 200, 300) includes a material with a first side surface (114, 214), a second side surface (116, 216), defining between them a thickness of the material. The material includes at least two self-sealing slits (126, 130, 226, 230) extending through the thickness and includes at least one frangible portion (150, 250) extending laterally between the at least two slits (126, 130, 226, 230) for at least part of said thickness of the material. The material includes confronting, openable portions along the at least two slits (126, 130, 226, 230) to define a normally closed orifice to minimize communication through the valve (100, 200, 300). The openable portions are constrained by the at least one frangible portion (150, 250) from moving away from each other into an open condition.
