A packaging device ( 2 ) for a packaging ( 1 ) has a chamber ( 4 ) to accommodate a pourable solid product. This chamber ( 4 ) can be closed off by a feed device ( 2 ) neighboring onto this chamber ( 4 ) whereby, with the feed device in the open position, an outlet ( 14 ) can be formed at the lower end of the chamber ( 4 ). The feed device ( 2 ) exhibits two valve flaps ( 11, 12 ) which are joined together by means of at least one spring-type element ( 10 ) such that, when the spring-type element or elements ( 10 ) are in the closed position, closure edges ( 16 ) on the valve flaps ( 11, 12 ) keep the chamber ( 4 ) closed off from the surroundings. Consequently, by means of pressure ( 31, 32 ) applied to the valve flaps ( 11, 12 ), an outlet opening of variable size can be easily achieved and thus, in a simple manner, controlled feed of pourable solid products.
