Abstract

A device for packing e.g. food products in gastight plastic bags comprises a head (5) on which the open end (3) of the bag (1) can be applied and retained in sealing manner, and means (21, 22) for first drawing air out of the bag and then blowing a protective gas into the bag. An axially reciprocating tube (9) is arranged in a passage (7) formed in the head (5) for conducting air to a vacuum pump (21) and protective gas from a supply (22). At a free end, the tube (9) carries a nozzle member (12) which, owing to the mobility of the tube, can be pressed against a product (2) contained in the bag when air is drawn out of the bag, thereby to ensure that air is drawn also from the immediate vicinity of the product. The nozzle member is in the form of a rod-shaped body (12) which, on the front side to be pressed against the product, has a crenellation with alternating projections (14) and indentations (15), at least some of the indentations being provided with nozzles.
