A closure for the filling opening (3) of a container (1) containing a pressure medium, in particular the filling opening of a vapour pressure sensor for the expansion valve of the evaporator of a refrigeration system, contains a first closure member (6) secured to form a seal, especially by means of a press fit, in the filling opening (3). In many applications, however, the closure is neither adequately sealed nor adequately strong. To solve that problem, a second closure member (7) is secured in front of the outside of the first closure member (6; 6a) to form a seal at the filling opening (3). |
