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.
