HERMETIC CLOSURE SYSTEM FOR A CONTAINER AND CONTAINER INCLUDING SUCH A CLOSURE SYSTEM

摘要

The invention relates to a closure system (1) and a container (30) forming a hermetic and/or sealed closure system for conditions in which pressure reductions or over-pressures occur inside or outside the container (30), which tend to cause the release of liquids or solids housed inside the container (30) or inside other containers located therein. The invention comprises: a system including a plurality of fixed flanges, projections or tabs (26) provided on the longer sides (22) of a body (8) of a container having a polygonal cross-section (30), optionally arranged in a structural manner, with first spaces (27) being provided alternately therebetween; a device made from metal or another rigid material (14), comprising a plurality of fixed flanges, projections or tabs (17) which are folded back, spaced apart from one another and designed to be form-fitted to the plurality of fixed flanges, projections or tabs (26) provided on the longer sides (22) of the body (8) of the container (30); and a polygonal lid (2) having a cross-section matching that of the body (8) of the container (30), said lid being provided with a seal (19) that can be inserted in the lower part (3) thereof and openings (41) in which bolts or screws (16) are inserted through a channel or groove (15) in the above-mentioned device (14) which is moved along the first two locking sides (9) thereof, which are the opposite longer sides.
