Patent ID: 8220662

Claim:
A device for feeding out liquid or substantially liquid contents, preferably food items such as mayonnaise, mustard, tomato ketchup etc., from a flexible squeezable purpose-made storage container ( 2 ), the device comprising: an outfeed container ( 3 ) in which said storage container ( 2 ) resting on the bottom ( 4 ) of the outfeed container ( 3 ) and being supported by sidewalls ( 5 ) of the outfeed container ( 3 ) is adapted to feeding out the contents therefrom; and a discharge means ( 6 ) at the top of the outfeed container ( 3 ) for pressure action from above upon the storage container ( 2 ) for feeding out at the bottom the contents from the storage container ( 2 ) by squeezing the discharge means; in which said storage container ( 2 ) has a connecting element ( 7 ) disposed internally in the storage container by means of which the storage container for outfeed, is connectable to an outer connecting element ( 8 ) by penetration of the storage container wall at the inner connecting element ( 7 ); and in which said storage container ( 2 ) is connected via the outer connecting element ( 8 ) to a valve means ( 9 ) with a valve body ( 10 ) which in a resting position (V) abuts against a valve seat and which, for outfeed, is openable (Ö) by the contents of the storage container ( 2 ) being pressed against the valve body ( 10 ) so that the valve body is caused to leave the valve seat; wherein: the valve body ( 10 ) has elastic properties and a normal shape in which the valve body abuts against the valve seat so that the valve body closes the valve means ( 9 ); the shape of the valve body ( 10 ) is variable so that when the valve body is subjected, for outfeed, to pressure from the contents of the storage container ( 2 ), the valve body is caused to change to a stretched shape and hence leave the valve seat; and the valve body ( 10 ) is adapted to reverting from stretched to normal shape when the pressure on the valve body from the contents of the storage container ( 2 ) ceases, in order to abut against the valve seat and rapidly close the valve means ( 9 ).
