20120243963 | PROCESS FOR FORMING THE WALL OF THE MOUTH OF A METAL CONTAINER OR PACKAGING, DEVICE FOR THIS PURPOSE AND PACKAGING OR CONTAINER OBTAINED - A process of forming the wall of the mouth of a cylindrical, metal container or packaging from a tubular ring that may or may not be molded that has to accommodate a sealing lid equipped with an elastic seal secured by a vacuum created in the container is characterized essentially by the use of a single element, the head carrying out the deformation of the internal diameter of the container by expansion to produce a bead together and simultaneously with a contraction that produces shrinkage above the bead of the mouth, the head comprising an expansible stationary part and a moving part that turns around the stationary part, the parts of the head being coaxial, which has the effect of compressing the metal and hardening it by organizing the metal molecules under two simultaneous stresses, which hardens the packaging and allows it to withstand the vacuum applied thereto. | 09-27-2012 |
20100218460 | PROCESS AND INSTALLATION FOR THE CONTINUOUS VACUUM PREPACKING OF FOOD PRODUCTS - Process for the continuous vacuum prepacking of food products that can be pasteurized and/or sterilized in a container closed by a cover that has no hooking element and is equipped with an elastic seal maintained by a forced vacuum, and the cover is opened by a vacuum-breaking system. During the placing under vacuum, the cover is kept apart from the previously filled container, superheated vapor is injected at a temperature, a flow rate and/or a time that allow the sterilization of the cover and the head space of the container by expelling air and incondensable products, in particular oxygen; the container is then pressed against the cover or vice versa, and a jet of cold water is sent onto the cover, which causes rapid cooling of the cover, the immediate condensation of the vapor phase in the head space of the container that allows the placing under deep vacuum. | 09-02-2010 |
