Abstract

Patente de Invenção: <B>"TAMPA DE ROSCA DE MATéRIA SINTéTICA PARA FECHO DE UMA GARRAFA OU SIMILAR"<D>. Tampa de rosca de matéria sintética para fecho de uma garrafa ou similar, com uma parte de rosca cilíndrica, que apresenta uma rosca interna para rosqueamento sobre uma rosca externa de um gargalo de garrafa, com um lábio de vedação 24, que se estende obliquamente para fora, com uma superfície de vedação 26 cónica, que com a tampa de rosca 2 rosqueada se encosta em uma borda de vedação 28 externa da superfície frontal 16 da boca da garrafa. Na superfície de vedação 26 cónica estão previstas cavidades 32, que se estendem de uma região, que com tampa de rosca 2 rosqueada se situa próxima ao lado de fora da borda de vedação 28, para a borda 34 do lábio de vedação 24 e estão em ligação com o entorno. No abaulamento em forma de cúpula do fundo 6 da tampa de rosca 2, o lábio de vedação 24 desliza com sua superfície de vedação 26 sobre a borda de vedação 28. Se a pressão na garrafa e, desse modo, o abaulamento do fundo 6, for suficientemente grande, então as cavidades 32 chegam à região da borda de vedação 28 e criam, desse modo, uma passagem do interior da garrafa para o entorno, de modo que a sobrepressão pode escapar. As propriedades da válvula de sobrepressão formada são determináveis com precisão e duradouras.Invention Patent: <B> "SYNTHETIC THREAD COVER FOR CLOSING A BOTTLE OR SIMILAR" <D>. Plastic screw cap for closing a bottle or similar, with a cylindrical thread part, which has an internal thread for threading on an external thread of a bottle neck, with a sealing lip 24, which extends obliquely to outside, with a conical sealing surface 26, which with the screw cap 2 threaded against an external sealing edge 28 of the front surface 16 of the mouth of the bottle. In the conical sealing surface 26, cavities 32 are provided, extending from a region, which with screw cap 2 is located close to the outside of the sealing edge 28, to the edge 34 of the sealing lip 24 and are in connection with the surroundings. In the dome-shaped bulging of the bottom 6 of the screw cap 2, the sealing lip 24 slides with its sealing surface 26 over the sealing edge 28. If the pressure in the bottle and thus the bulging of the bottom 6, is large enough, then the cavities 32 reach the region of the sealing edge 28 and thus create a passage from the inside of the bottle to the surroundings, so that the overpressure can escape. The properties of the formed overpressure valve are precisely determined and long-lasting.
