ES218566U - Plug with precinct for bottles. (Machine-translation by Google Translate, not legally binding) - Google Patents

Abstract

Stopper with seal for bottles, particularly applicable to those whose mouth is provided with an external bead, constituted by a cap obtained in semi-rigid plastic material, and characterized by the disposition in its interior of a cylindrical recess that descends from its upper base and by the configuration, on the inside face of its side wall, of a stepped upper rib and of an annular ruffled rib, between which a peripheral groove is located, between said ridged rib and that recess there being a clearance substantially less than the thickness of the rib. Refrain from the mouth of the bottle; and further characterized by the determination, on its side wall and on said ridged rib, of an annular and continuous line of weakness over which there is a flap radially outside the plug and below which, on the side wall, a narrow groove is made that reduces its thickness in an area adjacent to the said line (which is the one of break for opening) whose width is analogous to that of the aforementioned fin, all operatively arranged so that when originally closing the bottle by the most suitable procedure, the cylindrical recess is inserted snugly into the mouth of the same by sealing it, and its annular ridge is placed under pressure under the bead of the bottle keeping the closure and the cap fixed to it, while, for initially opening said bottle, that line of weakening must be broken by a pressure applied upwards on the outer wing, whereby the stopper will be sprecintado and divided into two parts, serving the top of them obturator for future closures and openings.
