Abstract: The device comprises a removable cap (20) for closing the neck of a receptacle (3), and a peelable membrane for hermetically covering the lip of the neck. In order to guarantee good sealing of the receptacle when it is reclosed with the cap, the peelable layer of the membrane is adapted to cover only an inner zone (61) of the lip (6) of the neck (3), the cap being provided internally with a skirt (24) for bearing in leaktight manner against an outer zone (62) of the lip that is distinct from the inner zone (61), and said skirt is plastically deformable between a generally cylindrical configuration and a flared configuration, the inside face of said skirt presenting a transmission surface (244) for transmitting a bearing force (F2) associated essentially with co-operation between the skirt in its flared configuration and the lip of the neck.

Abstract: A push-pull closure which includes a base for securing to a container and which base includes an upper plug which seats within an opening in a valve lifter which is moveable with respect thereto between a closed position and an open position and wherein a cap is provided for covering the valve lifter when in a closed position. A tamper indicating seal is applied over a portion of the top of the valve lifter and the plug of the base in order to provide a seal therebetween and to provide evidence of tampering or of first opening of the valve lifter from the closed position to the open position.

Abstract: A push-pull type closure includes a collar with an internal thread, a button associated with the collar, and a cap covering the button before the closure is first open, the cap including a tamper-proofing strip which is non-releasably confined in a groove of the collar, the transverse section of the tamper-proofing strip having a profile in the shape of a U which is open at the top, and the annular strip including an extreme portion which becomes lodged in the hollow of the U during crimping.

Abstract: A stopper for a dispensing container having a body portion from which a pour spout extends, which spout is closed by a cap and wherein the stopper further includes a diaphragm member for surrounding the spout and sealing the body portion thereof and which diaphragm also includes a vertically extending band having a slot therein for receiving a locking flange extending from the cap with the band being severable from the diaphragm upon opening of the cap to thereby provide a guarantee strip to indicate opening of the stopper.

Abstract: A combination closure assembly and container wherein the threaded neck of the container includes two series of notches along the base thereof and wherein the closure is provided with a tamper indicating guarantee strip which is lockingly engaged with a first of the series of notches so that the strip will be severed from the remaining portion of the closure assembly if access is attempted into the container and wherein the closure assembly also includes a conical sleeve which is engageable with the second of the series of notches upon the severance of the guarantee strip in such a manner as to prevent the closure assembly from being removed from the container.
