Abstract
The collar of the pump clamps the top wall of a closure against an underlying, external flange on the pump body, and although the collar is always a fixed, predetermined distance from the flange, a variety of closures with differing top wall thicknesses may be accommodated by the collar because of the yieldable nature of an integrally depending element at a lower periphery of the collar that makes the actual clamping engagement of the collar with the closure. Such element may be defined by an annular series of separate, deflectable segments around the periphery of the collar or by a continuous annular surface capable of deflecting away from the lip but maintaining forcible engagement with the top wall of the closure at all times.
