| 摘要 |
The present invention relates to a dispensing valve (1) adapted to allow dispensing of a product (2), preferably a food product, for example a beverage, from a container (3) which is preferably closed and has the ability to collapse when product is dispensed therefrom. The dispensing valve has an elastic membrane (7) with one or more valves (1a), which is/are closed when the membrane (7) assumes an initial position (A), and is/are open when the membrane assumes a stretched position (B) to allow dispensing of the product out of the container. When the membrane assumes its initial position (A), the valve (1a) or valves have contact with at least one support member (15), which prevents the valve (1a) or valves from opening, whereby air is prevented from passing through the valve (1a) or valves to product (2) present in said valve or valves. |
