摘要

The unit has a mechanical base part (54) connected with a delivery connecting piece of a liquid container (36) and comprising a valve body (70). The valve body is coupled with an operating element (102) whose outer diameter is smaller than that of the base part. The operating element is elastically deformable, and exhibits the outer diameter of 0.2 to 0.4 mm. The operating element comprises multiple recesses, which are equally distributed along a circumferential direction. A valve housing (58) comprises a non return valve (96) that opens toward an interior of the container.
