A packaging device (2) for a packaging (1) has a chamber (4) to accommodat e a pourable solid product. This chamber (4) can be closed off by a feed devic e (2) neighbouring 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.
