Patent ID: 7993609

Claim:
For a chemical compound or mixture that expels at least one gas that is generally not poisonous, a container comprising resilient, self-sealing septa and a shell defining, surrounding and encapsulating a chamber in which said compound or mixture is contained, said shell having first and second portions each integrally formed and comprising (i) an outer rim and (ii) a containing surface, wherein the containing surface of said first portion has at least one first area and at least one second area, said second area being thinner than said first area so that said gas may more readily permeate from said chamber through said second area, wherein each of said first and second portions has an orifice wall surrounding an opening through its containing surface sealed by one of the resilient, self-sealing septa such that said compound or mixture can be withdrawn from said chamber through any of the resilient, self-sealing septa, and wherein said containing surface of said second portion further comprises at least one first area and at least one second area, said second area being thinner than said first area so that gas may more readily permeate from said chamber through said second area.
