This invention relates to a closure which serves hermetically to close - though being easily reopened - a bottle or similar container, which possesses a neck having a dispensing orifice, a neck frontal face surrounding said orifice and an orifice bead located below the latter and having a constriction on its underside, and which closure comprises a cap serving as the head of the closure, with an upper cap wall (or roof wall of the cap) and a cap side wall circumferential about the latter and possessing slot means, extending from its lower rim and transversely to the latter, to permit it to splay (or spread) on being mounted on the mouth of the bottle, and with an inner annular head, projecting inwards from the inner face of the cap side wall and intended, in the closing position, to engage with the underside of the orifice head of the bottle, a sealing element, provided on the inner face of the upper cap wall and serving, in the closing position, to seal the dispensing orifice of the bottle, a lifting element which may be actuated by the finger and is located on the actuating side of the cap, and a fixing device which, in the closing position, annularly bridges each slot present in the cap side wall, by sealingly pressing the inner annular bead of the cap side wall against the constricted underside of the orifice bead of the bottle, and which is linked to the cap side wall in at least one region, remote from the actuating side of the cap side wall; the fixing device comprises at least one tensioning member which, in the closing position, is tensioned by being stretched radially to the cap side wall and as a result effects a compression of each slot present in the side wall and provides a uniform pressure, from all sides, of the inner annular bead of the cap against the underside of the bottle neck.

A closure which serves to close hermetically, but in an easily reopenable manner, a bottle or similar container, which possesses a neck having a dispensing orifice, a neck frontal face surrounding said orifice and an orifice bead located below the latter and having a constricted underside, and which closure comprises a. a cap serving as the head of the closure and having an upper cap wall and a cap side wall circumferential about said upper cap wall and possessing slot means extending from the lower rim of said cap side wall and transversely to said rim, to permit said cap side wall to splay on being mounted on the mouth of the bottle, said cap side wall having an inner annular bead projecting inwards from the inner face of said cap side wall and destined, in the closing position, to engage with the constricted underside of the orifice bead of the bottle, b. a sealing element provided on the inner face of the upper cap wall and serving, in the closing position, to seal the dispensing orifice of the bottle, c. a lifting element which may be actuated by the finger and is located on an actuating side of the cap, and d. fixing means which peripherally bridge each slot present in said cap side wall, at least when in the closing position, by sealingly pressing said inner annular bead of the cap side wall against the constricted underside of the orifice bead of the bottle, said fixing means being linked to the cap side wall in at least one region, remote from the actuating side of the cap side wall, said fixing means comprising tensioning means which, in the closing position, are tensioned by being stretched radially to The cap side wall in a direction toward said actuating side and as a result effects a compression of each slot present in the side wall and provides a uniform pressure, from all sides, of the inner annular cap bead against the underside of the orifice bead of the bottle neck.
