Abstract
A cap (18,120) and a thrust washer (62,128) seal a flexible silicone dispensing tube (10,118) to a neck (20,114) of a container (12,116) which holds a fluid to be dispensed. The thrust washer is shaped to inhibit contact between a lip (50,110) of the dispensing tube and the interior of the cap so that the soft material of the dispensing tube is not damaged when the cap is screwed on to the neck of the container. The thrust washer slides on the cap as the cap is screwed on to limit sliding movement relative to the dispensing tube. A dust cover (24,138) protects the dispensing tube during shipment and storage. The dust cover is attached to the cap by a frangible portion (66) which is broken prior to dispensing the cleaning fluid. A lower projecting ring (86,134) on the thrust washer prevents the dust cover from compressing and damaging the lip of the dispensing tube.
