A container (1) with a portion dispensing device for dispensing portions of a product from the container. The container has a main reservoir (2) for storage of product. The portion dispensing device comprises a variable volume product chamber (30) and associated restoring means. The variable volume product chamber (30) has a product outlet and an outlet valve (45). The product chamber also has a product inlet in communication with the main reservoir (2) and an inlet valve. The variable volume product chamber (30) has a volume that is reduced upon increased pressurization of product in the main reservoir (2) of the container (1), and that is increased, at when the increased pressurization of product in the main reservoir (2) of the container (1) is removed. The inlet valve (60) closes the product inlet upon increase of pressurization of the product in the main reservoir (2) so that product passes from the chamber via the product outlet. The inlet valve (60) opens the product inlet upon removal of said increased pressurization.
