Fastener with cap, e.g. for liquid soap in showers

摘要

The fastener has a cap (1) and a cover. The cap contains an easily deformable sealing element (2), forming a dispensing aperture in the deformed state. The sealing element is held on one side by a support element (17) of the cap and on the other by a holding flange against which the sealing element is pressed. The sealing element can be pressed out when lifted off the support element, putting it in the dispensing position. The sealing element has a permanently open central dispensing aperture (23), sealed against the support element in the closed position.
