Abstract

1436471 Vacuum packaging W R GRACE & CO 11 Jan 1974 [29 June 1973] 01334/74 Heading B8C To avoid the problem of evacuating all air from a bag-wrapped food product when the product contains surface crevices the filled bag is placed in apparatus which first evacuates air surrounding the bag to lift the bag off the produce and then evacuates air from inside the bag causing the bag to collapse on to and tightly enclose the produce; the bag mouth is then sealed and the package passed through a hot air tunnel or hot water bath to shrink the bag. This final step seals any pin holes in the bag by tight pressure against the product. The apparatus comprises a base 2 and hinged cover 3 forming a first compartment 4 and second compartment 5. The bag mouth is held in a guide 13 and passes through an apertured wall 11, 12 to devices 19-22 which apply a metal clip to the bag mouth and cut off excess material or alternatively heat seal the bag. Gathering arms 25 compress the bag mouth and a clip 37 fed from a magazine (Fig. 7, not shown) by a plunger 24 is forced against an anvil 19. When a filled bag is placed on a conveyer 14 in the apparatus, closure of cover 3 trips a microswitch thereby starting the sequence of operations commencing with evacuation of compartment 4. A pressure sensor in chamber 4 sends a signal to an electric drive motor for the sealing and cutting devices. The bags are gas impervious and may be of polyethylene, ethylene vinyl acetate copolymers or of a vinylidene chloride copolymer.
