| 摘要 |
A pressure control valve (2) for a packaging container (1) consists of a valve base (5) with a valve hole (6), a valve membrane (7) which extends over said valve hole and covers the valve base, spacers (8), and a viscous sealing compound between the valve base (5) and the valve membrane (7). In order to provide a relatively large supply store for the sealing compound, the valve membrane (7) is fixed only in a punctiform manner on the valve base. For this purpose, it preferably has cutouts in the corner regions (11), in the region of which cutouts the spacers (8), which adhere to the valve membrane with an adhesive layer (13) are also bonded to the valve base (5). <IMAGE>
