Abstract: A sealing cap for the mouth of a container facilitates both the sealing of new bottles containing unused contents, and the re-sealing of those bottles already in use so as to preserve their contents. The sealing cap includes an inner cap and an outer cap. The inner cap includes a shielding plate which is fixed on the mouth of a container, and an annular strip which is provided at the lower end of the outer circumferential wall of the inner cap. The outer cap, which is fixed on the inner cap, includes a top lid, and a main cap with a guide tube having a lower-end sharp edge located opposite the shielding plate. By removing the annular strip from the inner cap and pressing down the outer cap, the lower end of the outer cap engages the outer circumference of the mouth of the container, and at the same time, the lower-end sharp edge of the guide tube pierces the shielding plate. The user then opens the top lid of the outer cap to access the contents of the container.

Abstract: The present invention employs a plastic snap-on cap which engages the neck crown and is internally threaded to engage the neck threads of a conventional container. A foam gasket under the top of the cap prevents leakage by sealing against the neck lip. The cap has internal threads which snap over and then engage under the neck threads. Vertical "barriers" below the cap threads prevent unscrewing the cap so long as the cap skirt is intact. Score lines extend from the bottom edge of the cap skirt to above the internal cap bead which engages the neck crown and extend up to the cap threads. A tear tab is used to tear a vertical strip of the skirt which extends up between the score lines. The cap is thus tamper-evident since it cannot be removed so long as the cap is intact but can be removed by tearing the aforementioned strip. In one modification, a well is formed in the center of the cap.

Abstract: The present invention employs a plastic snap-on cap which engages both the neck crown of a container having a rectangular body and a neck having screw threads and is internally threaded to engage the neck threads of the conventional container. A foam gasket under the top of the cap prevents leakage by sealing against the neck lip. The cap has internal threads which snap over and then engage under the neck threads. Vertical "barriers" below the cap threads prevent unscrewing the cap so long as the cap skirt is intact. Score lines extend from the bottom edge of the cap skirt to above the internal cap bead which engages the neck crown and extend up to the cap threads. A tear tab is used to tear a vertical strip of the skirt which extends up between the score lines. The cap is thus tamper-evident since it cannot be removed so long as the cap is intact but can be removed by tearing the aforementioned strip. In one modification, a well is formed in the center of the cap.

Abstract: A capsule having a cap portion may be torn together with a pulling tab for tearing. The capsule comprises the cap portion and a skirt portion. Two weakening lines for tearing the cap portion are provided between the cap portion and the skirt portion. One of the weakening lines on the cap portion side is inclined to a top of the cap portion with a certain inclination as it approaches near the tear-terminating end. When pulling the pulling tab outwardly, the cap portion is torn along the weakening lines. Then, as it approaches near the tear-terminating end, the cap portion is torn upward toward the top, thereby opening the cap portion. Thus, the cap portion is removed from a cap of a bottle together with the pulling tab in one unit.

Abstract: Disclosed herein is a sealed tamper-evident container. The container comprises: a bottle having a side wall portion and an open mouth portion; a cap connected to the bottle mouth portion; a frangible label connected to the bottle side wall portion; a wrapper having an upper portion that overlies the cap and a lower portion that overlies the bottle and at least a portion of the label so that the cap is sealably fixed to the bottle; and means for securing the wrapper lower portion with the frangible label. The wrapper upper portion is removable from the container and the cap so that the cap can be separated from the container. Removal of the wrapper lower portion ruptures the frangible label; the label rupture serves as a visible indicia of the removal of the wrapper bottom portion from the bottle, and thus alerts the consumer to possible tampering.

Abstract: An improved tamper-indicating ring construction for threaded closures in which the closure and tamper indicating ring are provided with mating camming surfaces which are brought into contact when the closure is unthreaded from a container finish. The angle of the camming surfaces with respect to principal axis of the closure is substantially greater than the lead on the threads of the closure, so that when the closure is rotated to open the container, the camming surfaces push the tamper indicating ring downwardly to break the interconnecting bridges which link the ring and the upper part of the closure. The bridge members are positioned upon the camming surfaces and are oriented almost transversely to said principal axis, so as to be broken by shear rather than tensional stresses, this permitting the use of relatively stronger bridge members with the assurance that they will be broken with relatively little effort on the part of the user.

Abstract: A safety screw cap indicates prior opening of a container to protect consumers from prior contamination. The screw cap has an annular band encircling its lower end which is separated from the screw cap by a perforated line. The band is affixed to a fixing clement and the fixing element attached to the container when the screw cap is screwed in place. An unattached leader portion of the band can be lifted easily to peel the band from the container. As the band is peeled from the container, it is simultaneously tom from the screw cap at the perforations. Once the band is removed, the screw cap can be unscrewed and the container unsealed. Before peeling the band away, the screw cap cannot be unscrewed without causing obvious damage to the screw cap or band. In addition, the torque required to shear-separate the band from the fixing element, the fixing element from the container or the screw cap from the band is greater than that which can be applied easily by a normal adult.

Grippers are secured on the sleeve part and are pivotal at material weak points at the sleeve part. The grippers abut one another in flush fashion in a closing position and are joined to make a closed surface encompassing the bottle neck. The grippers have sides pointing toward one another. The grippers are rectangular as seen in a plan view and curved as seen in cross section. Tabs are associated with the grippers. The sides of the grippers and the tabs face one another and have alternating profiling mutually complementing one another in the closing position. The sides of the grippers are beveled toward the inside and overlap one another in the closing position.

Abstract: A cap composed of a snap-on, tamper-evident closure differing from others of this general type is formed with a central sleeve. The bottom of the sleeve is closed off by a removable plug. The exterior of the closure is formed with a bead. The water dispenser is provided with an adapter consisting of an open-bottom outer sleeve into which the neck of the container with the closure in place thereon fits. Centrally disposed in the outer sleeve is a dispenser tube. When the container is inverted its neck is inserted in the outer tube. As the neck and cap are lowered, the dispenser tube enters the cap sleeve and attaches to the plug. Continued lowering of the container causes the plug to slide out of the tube so that liquid in the container flows out through the dispenser tube into the dispenser. When the container is lifted, the plug (which has been attached to the dispenser tube) is pulled back into its original sealed position. The plug and cup are at all times discrete.

Abstract: A container system for reagents and other substances used in a medical diagnostic apparatus. The container system includes a vial made of blow-molded plastic, which can withstand lyophilization. The bottom portion of the vial has an annular groove and is shaped as a truncated cone below the annular groove. An auxiliary member can be snap-connected to the vial at the annular groove so that the vial will stand upright on a flat surface and contains a central aperture through which the vial remains in contact with the flat surface. The container system also includes a stopper at the mouth of the vial and a snap-on plastic cover to secure the stopper. The cover has a tab which is kept at a raised position by a lifter protrusion which bears against the stopper. The cover has tearslots which are ripped when the tab is pulled. One of the tearslots is shorter than the other and keeps the tab from being entirely detached from the remainder of the cover when the tab is pulled.

The tear band has a first rib which locks to the annular groove of the tube and a second rib which engages a recess in the cap to lock the cap to the tear band in a closed condition. The locking arrangement is such that the tear band must be removed to remove the support member from the tube or to open the cap.

Abstract: A tamper evident cap designed for threading onto a container by conventional bottle capping machinery. The cap includes a first set of spaced-apart lugs for engaging a second set of spaced-apart lugs of a container. The lugs of the cap and the lugs of the container neck are constructed to slide relative to each other upon threading of the cap onto the container while engaging each other to prevent unthreading of the cap from the container. The container neck is especially suited for glass bottles which must be blow molded. The cap includes a first skirt portion and a separable strip, and may include a second skirt portion that remains on the container neck after the separable strip has been removed. The gap between the skirt portions left by removing the separable strip indicates that the cap has been tampered with.

Abstract: A tamper evident seal and system for use on a variety of container and closure combinations providing a seal across the juncture of the container and closure and positive indication to consumers of tampering with the seal. The seal comprises a heat shrink band to which is applied at least one strip of a heat activated adhesive extending perpendicularly to the band's circumference and along the full length of the band. Perforations are provided along either edge to permit separation of the majority of the band from that portion to which the adhesive is applied. Indicia are provided on the band and on the container to indicate the presence or absence of the band. Application of the band to the container by heating causes the band to shrink into tight conformance with the container and closure obscuring the indicia thereon and bringing the adhesive into engagement with the container and closure.
