Patent ID: 7658295

Claim:
A closure system for a container that has an opening to the container interior, said closure system consisting of unassembled components comprising: a body which is either a separate structure for attaching to, and capable of extending from, said container at said opening or is a unitary extension of said container at said opening, said body having (1) at least one orifice for communicating with said container opening, (2) a bearing member comprising two spaced-apart walls which together define between them a channel with a reduced width passage that opens into a wider recess, and (3) at least one cantilevered, resilient, downwardly extending, laterally deflectable, retention finger projecting from one of said walls over at least a portion of said channel and that is shaped to accommodate temporary, elastic deflection relative to, and toward, said one wall from which it extends; and a lid adapted to be disposed on said body for accommodating lifting of said lid relative to said at least one orifice between (1) a closed position over said at least one orifice, and (2) an open position away from said at least one orifice, said lid including a pivot shaft for being received in said channel by being forced against and past said at least one retention finger which subsequently springs back over at least a portion of said channel; and wherein said retention finger has a distal end located in said reduced width passage to overlie a portion of the surface of said pivot shaft to define a positive retention system to prevent removal of said shaft from said channel.
