ABSTRACT:
A container closure is provided with a structure that permits it to be readily disassembled and assembled for use on a container defining an opening communicating with the container interior. The closure includes a body and a cover separate from the body. The cover is adapted to be pivoted about an axis between a closed position occluding a dispensing orifice in the body and at least one open position spaced away from the dispensing orifice. An axis-defining structure is provided on either the cover or the body for defining the pivot axis of the closure, and also includes a cam surface around the axis. The other one of the cover or body is provided with a receiving structure for engaging the cam surface to mount the cover to the body for pivoting about the axis. Either or both of the cover and body is elastically deformable. The deformable structure is least stressed when the cover is at one of the open positions. The deformable structure is most stressed when the cover is at over center point between the open and closed positions.
