A closure system is provided for a container. The system has a body for extending from the container at the container opening. The body defines a dispensing orifice. A lid is provided for covering the orifice. The body has a bearing member with two spaced-apart walls for defining a channel for receiving a pivot shaft on the lid. At least one deflectable finger projects from one of the body bearing member walls for being temporarily, elastically deflected to accommodate the insertion of the lid pivot shaft into the channel. The finger is resilient, and moves back over the lid pivot shaft to prevent removal of the lid pivot shaft from the channel.

What is claimed is: 1. 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. 2. The closure system in accordance with claim 1 in which said at least one retention finger is one of two downwardly extending, laterally deflectable, retention fingers that each projects from the same one of said two spaced-apart walls; and said body includes two of said retention fingers projecting from the other of said two spaced-apart walls. 3. The closure system in accordance with claim 1 in which said closure system is a closure for an end of said container wherein the container end defines said container opening; and said closure includes said body and said lid. 4. The closure system in accordance with claim 3 in which said closure is an article that is separate from said container; and said body is attachable to said container end over said container opening. 5. The closure system in accordance with claim 3 in which said closure body is a unitary part of said container and has (1) a peripheral wall that defines said container opening, and (2) an upwardly projecting spout that extends above said container opening to define said at least one orifice. 6. The closure system in accordance with claim 1 in which each said deflectable retention finger is arcuate. 7. A closure system for a container that has an opening to the container interior, said closure system comprising: a body which is either a separate structure for attaching to, and 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 that projects 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 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 disposed in said channel under said at least one retention finger; 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 which prevents removal of said shaft from said channel. 8. The closure system in accordance with claim 7 in which said at least one retention finger is one of two downwardly extending, laterally deflectable, retention fingers that each project from the same one of said two spaced-apart walls; said body includes two more of said retention fingers projecting from the other of said two spaced-apart walls. 9. The closure system in accordance with claim 1 in which said closure system is a closure for an end of said container wherein the container end defines said container opening; and said closure includes said body and said lid. 10. The closure system in accordance with claim 9 in which said closure is an article that is separate from said container; and said body is attachable to said container end over said container opening. 11. The closure system in accordance with claim 9 in which said closure body is a unitary part of said container and has (1) a peripheral wall that defines said container opening, and (2) an upwardly projecting spout that extends above said container opening to define said at least one orifice.
