Abstract
The invention relates to a housing comprising a venting device () which is arranged on the housing () and which allows an ambient pressure to be supplied to the interior of the housing (). The venting device () is made of a sleeve-like protective cap () with lateral openings () and a liquid-repellant membrane, and a cavity for receiving the membrane is formed in the interior of the venting device (). The membrane is arranged such that an opening, which is provided for the pressure supply, in the wall of the housing () is covered. In order to prevent the so-called teapot effect and therefore allow a light dripping of a liquid on the venting device (), the sleeve-like protective cap () has a narrow circumferential expansion () in the region of the lateral surface of the protective cap such that a defined dripping edge is formed.
