Patent

CA 2399726

A vacuum sealer is disclosed which makes use of a flexible flap (24.2) secured along one of its edges to a base plate (12.2). The base plate (12.2) on which the bag (B) to be evacuated and sealed is placed has a vacuum port (16.2) in it so that air can be sucked out from between the base plate (12.2) and flap (24.2). A groove (36.2) is provided in the base plate (12.2). This assists in keeping the bag mouth from being sucked shut before evacuation is complete. An anvil (26.2) and a sealer bar (14.2) form a weld across the bag adjacent its open mouth after evacuation.

L'invention concerne une scelleuse sous vide qui utilise un rabat (24.2) souple fixé le long d'un de ses bords à une plaque de base (12.2). La plaque de base (12.2), sur laquelle est placé le sac (B) à mettre sous vide et à sceller, présente une entrée à dépression (16.2) qui permet à l'air d'être aspiré entre la plaque de base (12.2) et le rabat (24.2). La plaque de base est pourvue d'une rainure (36.2), ce qui contribue à empêcher l'embouchure du sac de se refermer avant pompage complet de l'air. Une enclume (26.2) et une barre (14.2 )de scellement forment une soudure à travers le sac jouxtant son embouchure après pompage.
