Abstract: A display device and method aiming to protect access to audiovisual documents recorded in a memory. The display device includes a setting device for setting a masking threshold of the documents. The display device further includes a masking device for masking recorded documents the seniority of which in the memory is greater than the masking threshold.

Abstract: The invention relates to a display device and method aiming to protect access to audiovisual documents recorded in storage means. The device comprises means for: setting a masking threshold of said documents, masking recorded documents the seniority of which in said storage means is greater than said masking threshold.

Abstract: The invention relates to a screw cap made of a plastics material, the cap comprising a closing portion (3); optional sealing means (7) mounted in or integral with the closing portion (3); and a tamper-proofing ring (8) made in one piece with the closing portion (3). According to the invention, the cap comprises a breakable zone (17) of the outer portion (9) enabling it to be opened on unscrewing the cap (1) leads firstly to an empty space (18) between the outer portion (9) and the skirt (5), which empty space (18) is delimited downstream, with respect to the unscrewing direction of the cap (1), by at least one non-breakable fastening (19) which does not break on unscrewing the cap (1), and which is part of said link means (11), and secondly to a breakable zone (20a), to a cut (20b), or to a gap (20c) in the inner portion (10) so that, on unscrewing the cap (1), the tamper-proofing ring (8) remains associated with the closing portion (3).

Abstract: A screw-type closure device comprising a safety cap having a guarantee strip which includes a first ring connected to the bottom of a cap skirt by connecting bridges and a second ring assembled on the first ring by a peripheral zone of reduced thickness which allows the second ring to turn up inside the first ring. The second ring may be divided into at least two independent segments which are separated by gaps. The first ring of the guarantee strip includes at least one oblique groove of reduced thickness opposite one of the gaps in the second ring and which is torn to severe the guarantee strip from the container when the cap is removed.

Abstract: A skirt of a pourer has two wings each defining a bore whose geometrical axis, which is located outside the exterior of the skirt of the pourer, is parallel to a tangent line to the skirt. Each wing has a radial cut-out whose width is less than the diameter of the corresponding bore. The bores are open in the direction of the bottom of the pourer. The lid has two opposite lugs which snap into the bores of the wings.

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.
