Abstract: This invention relates to a dispensing stopper with rotating cap for pasty products, wherein axial displacement of the rotating cap is effected by cooperation of two series of oblique projections in contact and by cooperation of stops and oblique ramps. The base of the cap is further provided with a tearable guarantee strip.

Abstract: A tamperproof closure for a container having a threaded neck comprises a cap having an outside skirt threaded on the inside to be engaged on the neck of the container. The skirt is extended by a tamperproof band which is connected to the skirt by bridges of material that can be cut. The neck of the container is provided with a plurality of circumferentially oriented radial catches. The tamperproof band has a plurality of inside radial lugs having a profile complementary to the neck lugs, the catches and lugs being configured to permit passage of the latter over the former in the direction of screwing, and to oppose passage in the opposite direction. Below the threaded part of the container neck is provided a flange of cross section exhibiting a profile converging toward the bottom of the container. A face of each inside radial lug of the tamperproof band is beveled toward the direction of the cap top.

Abstract: A tight screw cap having a cylindrical outside skirt threaded on the inside surrounding a pan bottom having a circular bottom wall surrounded by a cylindrical lateral wall connecting it to the upper edge of the outside skirt of the cap. The outside diameter of this lateral cylindrical wall corresponds to the inside diameter of the threaded upper end of the neck of the container, the length of the cylindrical wall being less than that of the cylindrical skirt.The bottom wall of the pan bottom is connected to its lateral cylindrical wall by a part in the shape of a crown of bitruncated section delimiting, at the periphery of the bottom wall, an annular groove of approximately annular section projecting, in relation to the bottom wall, from the same side as the free end of the outside skirt.

Abstract: A closure device for bottles comprising a cap with a pilfer or tamper proof strip, and with thread conical screwing means on the neck of the bottle and on the cap. The screwing means comprises insert means adapted to cooperate with a cylindrical part of the neck bottle and a lip outside the insert and designed to provide a longitudinal positioning stop.

Abstract: A disposable container is provided with a unitary sealing assembly having the capability for indicating that the container has not been opened and including a disc portion for enclosing the opening of the container and a seal portion positioned between the disc portion and the opening of the container, and a threaded collar for engaging the opening of the container and for retaining the unitary sealing assembly to the opening of the container.

Abstract: The invention relates to a cap provided with a guarantee strip for stoppering receptacles with a threaded neck, wherein the guarantee strip is formed by at least two separate elements connected to the base of the skirt of the cap by two bosses, of which one, is located ahead of the other as the cap is screwed on and is more resistant than the other, said one boss being severed when the cap is unscrewed. The invention is particularly applicable to the stoppering of bottles of sparkling beverages.

Abstract: The present invention relates to a stopper having a sleeve with pouring lip for bottles and like receptacles with necks. Inside the sleeve is provided a transverse disc supported on spaced apart arms join to a perforated annular partition supporting the sleeve. When the liquid is poured out, it is guided between the periphery of the disc and the sleeve, at the same time that air is inducted through the upper openings of the perforated zone. The invention finds particular application in the stoppering industry.

Abstract: A temperproof closure element integrally formed from molded synthetic material. The top cap section has a series of outwardly spaced projections which cooperate with mating inwardly spaced projections on a tear strip. A locking collar is provided with a similar series of inwardly spaced projections corresponding with mating outwardly directed projections on the same tear strip. The thickness of material along each of the set of mating projections is diminished providing a zone of reduced strength so that the tear strip can be removed prior to first use of the container containing the closure element.
