Abstract: A closure (10) is provided and includes a tamper-evident band (40). The band (40) has a plurality of retaining flaps (60) which engage under a container neck annular retaining bead (23) when the closure is first applied. The flaps have a ratchet surface (86a, 190) for engaging a complimentary surface on the container neck (20). The flaps also have spacer means (85a, 85b, 186) for pushing them into a more vertical inclination under the bead (23). The ratchet arrangement and spacer means ensure reliable separation of the tamper-evident band (40).

Abstract: A closure cap for a container containing carbonated beverages has a head plate (2) and a substantially cylindrical cap skirt (4) extending from the edge (3) of the head plate (2). A cap thread (6) is provided on the inside (5) of the cap skirt (4). In the transition region (7) between the head plate (2) and the cap skirt (4) reinforcing ribs (8) are provided, which extend up to the head plate (2).

Abstract: A closure cap comprises in a transition range (7) between the cap base (2) and the cap skirt (3) a bulge (6) for pressing a sealing disk (5) against a container opening. The bulge (6) comprises an undercut (8) and in sections (9) is provided with weakenings (10) which give the bulge (6) a radial flexibility.

Abstract: A closure cap (1) with a cap base (2) and with a cap skirt (3) comprises an inner seal (4). The inner seal is provided with bleeding reliefs (11) which lift the sealing effect as soon as the cap base (2) is displaced axially upwards. The closure cap (1) comprises a first abutment and a second abutment (8). On screwing-on firstly the second abutment (8) comes into engagement with the container opening. By way of this a weakening zone (9) in the region of the cap base (3) is pretensioned to a predeterminable value. On account of the predeterminable pretensioning of the weakening zone (9) a bleeding at an exactly defined excess pressure is possible.

Abstract: A closure cap (1) for a container consists essentially of a cap base (2), of a cap skirt (3) and of a sealing disk (5) which bears at least partly on the cap base (2). A circumferential bulge (6) is arranged in the transition region (7) between the cap base (2) and the cap skirt (3). The bulge (6) serves for pressing the sealing disk (5) onto the container opening. The bulge (6) is divided by interruptions (8) into several blocks (9). On the inner side (10) of the cap base (2) there is arranged at least one rib (11) running radially outwards. The, rib seen in the circumferential direction, is located neighboring one of the interruptions.

Abstract: A closure cap for closure of containers possesses a closure base (2), a wall (3), and a pull-off ring (7). The pull-of ring is connected to the wall (3) at connecting points (8). In order to open the closure cap, a force is exerted onto the pull-off ring (7), by which means two vertical frangible lines (9) lying adjacent to the connecting points (8) will be destroyed. As a result, an area of the wall (3) can be bent outwards and opening of the closure cap will be facilitated.

Abstract: A snap-on seal arrangement comprising a container and a sealing cap is provided. The sealing cap comprises an elastically expandable cylindrical wall and at least one elastically deformable retaining bead for attachment to a container mouth having an external bead. An engagement surface of the retaining bead can be brought into effective engagement with an engagement surface of the external bead, wherein after the cap has been placed on, the engagement surface of the retaining bead of the sealing cap works together with the engagement surface of the external bead on the container mouth to enclose a radially outward-expanding gap. The retaining bead is elastically deformable such that the gap decreases in size or closes under the action of positive pressure in the container.

Abstract: The plastic snap closure possesses a snapping means (3) on the inside surface of the cap wall (2), said snapping means being able to be snapped over a bead on the container mouth. In order to display initial opening of the closure, approximately vertical weakened zones (4) are provided on the lower edge of the closure cap. The cap wall (2) will tear on initial opening of the snap closure in the area of at least one of these weakened zones (4).

Abstract: A closure cap with a tearable anti-tamper strip (3) have flaps (5) which extend radially inwards from the inside surface of the anti-tamper strip towards the cap base. With the closure cap in position on the container mouth, these flaps (5) engage beneath a circumferential bead (6) on the container mouth. In order to enhance the stability and resistance to bending of the flaps, their lateral edge areas (7) are directed inwards in such a way that, at least one position, they possess a lesser distance in relation to the cap axis than the flap centres (8). The facing surface (11) of the flaps (5) is directed towards the cap base (1) and is inclined towards the cap axis so that, on opening of the closure, the effective force (F) impinges on the centre of the flap relatively far out. The centre of the flaps (8) is here preferaly designed to be thicker than its lateral edge area (7).

Abstract: A closure cap that is connected captively with the neck of a container. To this end, a retaining ring is used to engage beneath a bead on the container mouth when the cap is in position on the container mouth. The cap wall is firmly connected with this retaining ring by the tether. The retaining ring at the same time serves as an anti-tamper security for the closure. In its original condition, the tether runs between the cap wall and the retaining ring along the circumference of the closure cap and is connected by nominal rupture bridge pieces not only with the retaining ring but also with the lower edge of the cap wall.

Abstract: Closure caps with anti-tamper strips (3) are used to visually display initial opening of a container to the public. The possibility of opening such a container without evidence should be prevented as far as possible. The possibility of stretching the anti-tamper strip (3), in order to then manipulate it past the bead on the container mouth, is here countered by an additional security ring (7). This security ring (7) is arranged coaxially to the actual anti-tamper ring (3). It is connected to the anti-tamper ring and mainly surrounds the lower area (5) of said anti-tamper ring. Access to the actual anti-tamper ring is considerably hindered as a result. In a preferred embodiment, the security ring possesses weakened zones (10) that break during manipulation, so that the interference will be visibly displayed to the outside.
