Abstract: A fitment and closure assembly useful with a gable-topped carton having a gable-forming panel with a pouring hole, through which contents are pourable from the carton, is molded from low density polyethylene. A fitment having a tubular spout formed with an external thread and an annular flange extending outwardly from the tubular spout, below the external thread, is attachable to the gable-forming panel so that the annular flange is attached to the gable-forming panel, around the pouring hole, and so that the tubular spout extends upwardly from the pouring hole. A closure having an upper wall, a tubular skirt with an internal thread and an upper shoulder, and a plug seal forming an annular recess between the plug seal and the upper shoulder is threadable onto the fitment so that the external and internal threads are interengaged and so that the upper end of the tubular spout enters the annular recess with an interference fit.

Abstract: A cap and container combination wherein the cap fits about the container in at least two closure positions. Two circumferential bands are provided around the skirt of the cap and there is an internal thread which engages an external thread about the container neck. In the first position, one band of the cap engages a circumferential slot about the container. The internal thread seals with the top of the container. The first band is removed and the container opened by removing the cap. In the second position, the second band engages the slot and the threads engage each other. In the second position, the second band is located about the container. It remains in position when and after the cap is removed. Tampering of the container and cap can be visually detected with this configuration. A bead about the container is formed of a reduced cross-section in portions circumferentially around the cap. This facilitates assembly and disassembly of cap and container.

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.

Abstract: An internal fitment has a bottom peripheral flange adapted to be ultrasonically welded or otherwise attached to a panel of a paperboard carton surrounding a hold in such panel. Above the flange is a spout which converges upwardly and has a cylindrical external locking bead. Above the spout is an outward slanted tear band and above the tear band is a reclosure cap having a top, a depending skirt formed with internal interrupted beads and a plug. The tear band is connected to the spout and cap by thin horizontal tear lines. A finger grip tab extends outwardly of downward with respect to the tear band so that the consumer may conveniently grip the tab, pulling it circumferentially around the spout to separate the tab from both spout and cap. The cap is dimensioned so that the skirt fits over the outside of the spout, the beads detachably locking under the locking bead. The plug seals against the inside of the spout to prevent spillage.

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: A tamper resistant filling and containment system useful in medicinal and related applications. A bladder includes at least two ports with one of the ports having a graspable, reciprocable tube inserted therein. The tube has an axially bore formed partially therethrough which terminates at side passages which communicate with the bladder when the tube is in a filling position. Movement of the tube to a second position prevents communication of the side passages with the bladder and a weakened portion of the tube located at the side passages permits the graspable or outer portion of the tube to be broken, thereby preventing access to the tube and movement thereof to the filling position.

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 blow molded container has a cylindrical neck portion with novel seven circumferentially spaced continuous spiral thread configurations on its exterior to immediately receive and engage an improved tamper indicating flexible cap comprising a top with an annular depending wall on its peripheral edge and seven circumferentially spaced continuous spiral thread configurations on the inner surface of the annular depending wall. The novel constructions enable the tamper indicating flexible cap to immediately engage the lead-in ends of the seven circumferentially spaced thread patterns on the exterior of the neck of the container without the heretofore necessary rotation of the prior art caps in order to engage the single spiral thread configuration on the neck of the container.

Abstract: A tamper resistant closure and a method of installing and removing that closure relative to a container where the container has a neck with external threads thereon and a ring located beneath the threads. The closure has a central portion with a periphery and a skirt extending from the periphery, a tear strip extending from the skirt, a tamper evident band extending from the tear strip and a movable flange extending from the band. The tear strip is affixed between the skirt and the band by a plurality of severable tabs. The flange is hinged to the tamper evident band and has equally spaced windows in it to make it flexible so that it can be stretched over the ring. When the closure is installed on the container, the flange is forced against an interior of the band and overrides the ring. Once the flange has overridden the ring, a free edge of the flange moves inward to rest against an outer surface of the neck beneath the ring.

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.
