Abstract

n additional circumferential packing ring is disclosed for sealing closures. It is made of foamy polyurethane or similar material and placed via a special mechanism, after the manufacture of closure is finished, into a special housing that same closure bears on its inner plane surface, or by injection, before same closure is extracted from mould. Said ring enables the tightness of closure via the foamy material, which is peripherally compressed between the rim of the container and the inner plane surface of the closure, without aimless waste of material, in case that an entire disc (washer) would be placed. In comparison to similar up-to-date sealing modes, the use of the foamy material or other materials is restricted to a minimum and this has effect to the weight and cost of the invention. Furthermore, the contact of the foamy material with the content is reduced so that the growth of noxious micro-organisms in food packages can also be minimized.
