Abstract
The pump is clamped to the top wall of a container closure by a pair of opposed, upper and lower clamping surfaces on the pump body which position the body to project down into the container. The lower clamping surface takes the form of a circular flange which is integral with the pump body and which is itself normally clamped between the top wall of the closure and the upper edge of the neck of the container when the neck is only slightly larger than the pump body, thereby preventing rotation of the body when the pump plunger is rotated to either lock or unlock the same from a fully depressed, stored position. When the pump is used on a large closure having a wide neck whose upper edge therefore fails to clamp against the pump flange, the pump body will nonetheless be held immobile by a series of flat surfaces therearound which matingly interlock with complimentally configured flat edges in the closure opening through which the pump body extends.
