Abstract (en)
[origin: WO8601489A1] The container comprises an outer envelope (1) and an inner envelope (2) which contains a certain quantity of a product to be extracted. The cover (4) of the container has a membrane (6) at its top part provided with a hole (7) of the extraction of the product. In a rest position, the membrane (6) sealingly bears against a plug (8) which then closes the hole (7). The plug is connected by means of strips (10) to a socket (11) secured to the inner envelope (2) made of flexible material. The cover (4) and the socket (11) are interconnected. When exerting a pressure on the outer envelope (1), an over pressure is generated in the space situated between both envelopes by means of a valve which closes said space. A predetermined quantity of product contained in the inner envelope (2) is thus ejected between the plug (8) and the membrane (6) which thereafter comes back to its rest position where it ensures the protection of the product by preventing outside air from entering.
