DE1586684C - Method for the tight closure of containers consisting of a rigid container base and a rigid lid - Google Patents

Description

The coffin consists, as usual, of a housing, can be any gas, e.g. B. Carbonic acid, Fonnol-

After completion, a light lock is then folded in the coffin, the upper free edge 8 of the negative pressure is maintained so that the joint in the welded seams 6 of the housing remains open, because when the lid is put on, the protruding protrusion is welded to the outside results in a reduction in volume. Then the cover is welded to the free edge 9 of the cover film and thus receives the connection 11, the cover is placed on top and ^{fastened with a sealing weld 10 on the free 30} with the screws 4.

Edge 8 a connection 11 is welded on. The invention is also applicable to coffins, consists of a connection piece made of thermoplastic material which has safety valves for the gas outlet. A cannula is then attached to this nozzle, although this is theoretically unnecessary. If the lead coffins are peeled to a vacuum device, the joint must be closed with sufficient clearance. After making at least one ^a5 , in order to have enough partial vacuum in relation to the welding joint, through which a movement of the inward can protrude, thereby causing a welding joint inward, the Ka melting during lead welding will be avoided. The nozzle connected to a putrefactive agent is also suitable for metal coffins and devices. This means plastic coffins.

1 2 and so the pouring spout does not come into contact with the interior. For sealing the contents of several rigid elements together 1. A method for the tight closure of containers from set-up can give this French a rigid container base and a rigid 5 patent no suggestion. For this purpose, be-lid existing containers with the help of special attention must be paid to the fact that from several rigid containers assembled from each of the rigid parts in the vicinity of the separating elements, the contents are enclosed in a joint made of weldable material of the shape determined by the container, which straps should be used when closing the ßen, irrespective of whether the container is only connected to one another in a sealing manner, partially or not at all.
