| 摘要 |
The present invention relates to a device for discharge of liquid or substantially liquid products (2), preferably foodstuffs, e.g. mayonnaise, mustard, ketchup or dressing, from a compressible container (3) made of flexible material, preferably of plastic bag type. The container (3) is placed in an outer container (7) and is compressible by a compression device (4) in order to feed product (2) out therefrom through a nozzle (6). The invention is characterised in that a compression means (9) which forms part of the compression device (4) is disposed on a piston (17) adapted to being subjected to movements in a portioning direction (P3) so that the movable compression means (9) squeezes the container (3) in the outer container (7), and that the piston with its compression means (9) can perform a return movement in a return direction (P4) which is opposite to the portioning direction (P3).
