Abstract: This relates to an improved container tamper evident bead and neck finish arrangement which provides improved tamper evident band breakage upon removal of an associated closure. Most specifically, beneath the customary retaining bead, a container neck finish is of corrugated or scalloped configuration and is of a size whereby the tamper evident band or a retaining bead thereof is stretched across the space defined by a groove between two adjacent ribs so as to provide for a degree of interlock between the stretched tamper band and the container neck finish such that the tamper evident band is restrained against rotation with the remainder of the closure when the closure is rotated to effect removal thereof. This provides for a much quicker and more reliable breaking of the webs joining the tamper evident band to the closure skirt.

Abstract: Tamper-evident closures for application to containers are disclosed. The closures include a cylindrical side wall, a series of frangible bridges, and an annular skirt, and the skirt includes on its inner wall an upper raised portion, a lower raised portion, and an indented central portion therebetween. In this manner, an annular collar on the container can be locked between these upper and lower raised portions on the annular skirt portion of the closure, and this can result in improved consistent fracture of the frangible bridges upon removal of the closure from the container.

Abstract: A one-piece molded plastic closure having a tamper-indicating band connected to the closure skirt by rupturable means. The tamper band uses series of solid interiorly projecting beads that come in contact with a transfer bead on the container as the closure is unscrewed. The engagement of the beads and container breaks the band by rupture on the connection means. The beads in the band are arranged in tiers at three different heights on the band. A thick cylindrical section at the bottom of the band assists initial capping. The beads are disposed in the band at an angle equal to the pitch angle of the container threads. This eliminates need for top pressure in capping by the beads following the container thread lowering and driving the beads over the container's transfer bead locking the band in place.

Abstract: The invention relates to a screw cap for a container neck, comprising an internally threaded cap portion (1) and a security ring (6) joined by means of inclined bridge portions (7) to the cap portion. The sealing ring (6) is resiliently deformable and is designed to be forced over and past a collar (5) around the neck of the container, when the cap is being screwed on for the first time. Recesses (8, 9) are provided in the lower part of the cap portion and/or the upper part of the sealing ring, in which recesses the bridge portions (7) are secured. The bridge portions are so inclined that the upper edge of the security ring can engage the lower edge of the cap skirt when, during screwing on of the cap for the first time, the security ring (6) engages the collar (5), without undue bending of the bridge portions (7), so that the cap portion can support the security ring (6) while the latter is forced over the collar (5).

Abstract: A tamper-evident closure adapted for assembly with a container includes a band which, upon first opening, completely separates from a cap portion and which, upon reclosing the container with the cap, is dislodged from engagement with the container to insure that the band falls freely around a neck portion of the container to provide a substantial space between the cap and the band and thereby provide readily discernible evidence that the container has been previously opened.

Abstract: A closure for a container which includes a cap portion having a snap-on or friction fit with the neck finish and wherein the cap portion remains tethered to the container by way of a tethering strap extending between the cap portion and an anchoring band permanently affixed to the container neck finish. The tethering strap and the anchoring band are part of an extension of the skirt of the closure cap with the tethering strap being defined by a continuous weakening line of which portions must be ruptured in order to release the cap portion and to define the tethering strap. The rupturing of these portions gives indication of tampering.

Abstract: A tamper indicating package comprising a container having a neck with external threads formed thereon and a plastic closure comprising a top panel and an integral depending annular skirt. The skirt has integral internal threads formed thereon complementary to the threads on the neck of the container. The container has an annular locking bead positioned axially below the threads, and the skirt has a ring at the lower end thereof connected to the upper portion of the skirt by a plurality of circumferentially spaced integral bridge portions located below the threads when the closure is on the container. The ring has a radially inwardly extending annular rib engaging beneath the locking bead of the container when the closure is on the container. The skirt has an annular groove formed therein in the area of the bridge portions, the groove being formed after molding by deforming an annular portion of the skirt thereby displacing material in the annular area axially and stressing the material in the annular area.

Abstract: A tamper resistant closure for screw top and other containers is provided which resists and visibly discloses attempted tampering. A heat shrinkable plastic sleeve including at least one row of longitudinal mechanical weakness, such as a line of perforations, snuggly surrounds both the screw cap and a portion of the neck of the associated container. Sharp protruding teeth integral to the covered portion of the container neck interfere with the longitudinal weak areas when the shrunk sleeving is forcibly rotated during an attempted tampering, causing a portion of the plastic material to rupture and indicating tampering. By providing a second row of longitudinal weakness, such as a second closely spaced parallel line of perforations, a tear-away portion results whereby the features which provide indication of tampering also provide a convenient means for desired removal of the protective sleeve by the intended user.

Abstract: A tamperproof closure is disclosed for use with a container nozzle having a circular transfer bead. The closure includes a top and depending sidewalls which are defined from a bottom extension by a circular weakened seam. An interior groove is provided in the bottom extension of diameter less than the diameter of the transfer bead. A plurality of slots are formed in the bottom extension between the weakened seam and the interior groove to provide a degree of flexibility. The closure may be applied to the nozzle in either a threaded connection or in a snap ring connection. Upon opening the container, the frictional engagement between the transfer bead and the interior groove will cause the bottom extension to remain tightly affixed to the transfer bead, thereby causing the closure to sever along the weakened seam.

Abstract: A plastic cover fits over the top and partially down the sides of a corked wine bottle. Such a bottle conventionally has an external bead a short distance below the top of the neck. The cover has a skirt formed with a complementary bead which fits tightly over such bead, the plastic material stretching sufficiently for the cover to lock into place so that it cannot be removed with the skirt intact. A tear strip is formed substantially circumferentially around the cap bead by a pair of vertically spaced score-lines. The skirt is grooved to form a tear tab which extends circumferentially along a portion of the bottle bead. By tearing off the tear strip the portion of the cap thereabove can be removed. As a supplemental means of access for removal of the cork, the top disc of the cap may be formed with a circular score-line.

Abstract: A tamper-evident closure for sealing a package cooperates with a separately applied indicator ring, which is torn apart during the opening of the package, so that a portion of the indicator ring drops clear of the closure to indicate that the closure has been turned at least partially off of the package.

Abstract: A closure cap, in particular for bottle-like containers, having an element assuring intactness, which is connected by tear strips with a cap portion and remains on the container after the closure has been opened for the first time by tearing the tear strips, characterized in that a separation seam separating the element assuring intactness from the cap portion has a first set of alternating segments disposed in zigzag fashion periodically about the circumference of the element insuring intactness and additionally has a second set of alternating segments similar to said first set and carried by the cap portion. The first and second sets of segments mesh with each other. Tear strips are carried by the cap jacket between the element insuring intactness and the cap portion. The first and second sets of segments mesh with one another and serve as a coupling means during closure.

Abstract: A tamper evident closure for bottles and containers includes a cap and a tamper-indicating lower ring or belt, those two parts are linked together by a weak breakable circumferential area, which will break at opening of the container leaving behind the lower ring. This closure is the result of a simplified manufacturing process that forms the breakable circumferential area by forming misaligned cuts about the circumference of the closure between the upper cap and lower ring. Upon opening, the lower ring moves down on the neck of the container. Upon reclosing, the space between the cap and ring makes the prior opening of the bottle very evident.

Abstract: A flask for sterile liquids capable of supporting a terminal sterilization of pharmaceutical quality. The flask has a tamper-proof closure comprising a cap screwed on its neck and a locking ring formed in two parts axially superposed and joined by a breakable zone. One of the parts is axially carried away by the cap during opening of the flask and the other part is held axially by a shoulder formed on the neck. The cap encloses a seal made of elastomeric material inserted between its bottom and the edge of the neck, this seal being axially solid with the cap and comprising a skirt applying itself against the inner surface of the neck in a bacteriologically sealproof manner along a height sufficient to ensure a bacteriological closure seal until the locking ring is broken.

Abstract: Tamper-evident closures include a threaded cap and a tamper-evident ring removably connected to each other by break-away tabs adapted to break when the cap is rotated in a direction to remove it from a cooperating container. The cap and ring have cooperating surfaces for transmitting closing rotational movement of the cap to the ring to thereby rotate the cap and ring together during closing of the container to thereby prevent separation of the cap from the ring at the break-away tabs. The ring further includes at least one locking surface adapted to engage a corresponding surface on a container to prevent the ring from rotating in the opening direction of rotation, whereby rotation of the closure to open it will cause relative movement between the cap and ring to sever the break-away tabs. A method of molding the cap, tamper-evident ring and break-away tabs as a single member also constitutes a part of the invention, as well as the particular container constructions adapted to cooperate with the closures.

Abstract: A tamperproof closure is disclosed for use with a container nozzle having a circular transfer bead. The closure includes a top and depending sidewalls which are defined from a bottom extension by a circular weakened seam. An interior groove is provided in the bottom extension of diameter less than the diameter of the transfer bead. A plurality of slots are formed in the bottom extension between the weakened seam and the interior groove to provide a degree of flexibility. The closure may be applied to the nozzle in either a threaded connection or in a snap ring connection. Upon opening the container, the frictional engagement between the transfer bead and the interior groove will cause the bottom extension to remain tightly affixed to the transfer bead, thereby causing the closure to sever along the weakened seam.

Abstract: Tamper-evident containers are disclosed, including a container having a neck portion and an annular collar portion located below the neck portion, and a closure for application to the container including a one-piece closure body having a horizontal end wall and a cylindrical side wall including an upper portion, a depending lower skirt portion, and an intermediate side wall portion therebetween.
