Abstract
A closure is provided for use on a container. The closure includes a body for being mounted to the container over the container opening and defines a dispensing orifice. A separate lid is mounted on the body for pivoting between a closed position and an open position. A resiliently deformable biasing member extends from the lid and has a distal end for engaging the body. Restraining walls are provided on the body for restraining the distal end of the biasing member whereby the biasing member is most stressed when the lid is at an over center position between the open and closed positions to thereby bias the lid toward one of the open and closed positions.
