<p>Specific automatic closing system for packages used as containers, principally for compressible or elastic materials, but also for inert equipment or articles which may require the same system, for practical or economic reasons, in any field whatever. The system relates especially to the pressure fitting of a cover (1) equipped with foldable rims (2), which is guided and forcibly pushed inside the container (3) with the aid of a piston. This container is provided on its periphery and in its top part with a pleat (4), or profile, disposed in the opposite direction to that of the rim of the cover. The assembly is locked, after ascent of the pushing piston, by means of the phenomenon whereby the compressed materials assume their initial volume, or, in the absence of this phenomenon, by means of the addition and fastening under the cover of an elastic material, in the case of a packaging containing a material, an article or an inert item of equipment. <IMAGE></p> |
