Abstract:
1. Device for controlling the flow of a liquid by applying an opposed external force to actuate the said device comprising in combination: a hollow body portion defining an interior for accommodating fluid received from a liquid source, said body portion including a fluid inlet end communicating with said interior for receiving liquid from the liquid source and a fluid outlet end spaced from said fluid inlet end; and a deformable closure connected to said body portion and extending across the fluid outlet end of said body portion, said closure including an outer closure surface and an inner closure surface spaced from said outer closure surface and having a plurality of slits formed therein at an angle opposing each other, said plurality of opposing angled slits being spaced from one another and extending between said outer closure surface and said inner closure surface, and at least one portion of said closure being located between and defined by said plurality of opposing angled slits and cooperating with the remainder of said closure to maintain said slits from said interior, said at least one portion changing shape upon application of said external forces on said device to open said plurality of slits and form a plurality of openings allowing said liquid flow from said interior.
