  • Patent number: 5012940
    Abstract: An originality guarantee for closures of containers, particularly bottles. It has a label (12) which, after it has been removed or damaged, indicates that the closure has been opened. The closure portions (4,6) which are to be moved apart when it is opened are provided with flat recesses for receiving the label (12). The recesses merge from one closure portion into the other or others and together have the external shape and size of the label. Such a label indicates that the closure has been opened when it is torn or cut through. The invention also prevents the possibility of the label being removed and glued on again. This purpose can be served by the said recess which makes it impossible for a user to engage beneath the label with a finger nail or a tool and to lift it away. Instead of a recess a horseshoe-shaped wall (22) can be provided which surrounds at least a portion of the label. It may be broken away so that the user has access to the label.

  • Patent number: 4978016
    Abstract: A closure for a container has a tamper indicating band with band retaining means in the form of a conical hoop. The hoop is hinged to the band by arcuate hinges which are spaced by narrower windows along the hinge line, the windows extending partway toward but not to the inner edge of the hoop. As the hoop is turned inside out from its as-molded position to its use position, the inner edge of the hoop deforms radially adjacent the windows and thereby relieves hoop strength. As a result of the deformtion, the hoop in its use position assumes an advantageous polygonal peripheral shape rather than a circular shape.

  • Patent number: 4971212
    Abstract: A tamper indicating package comprising a container having a finish with external threads thereon and a plastic closure comprising a base wall and a peripheral skirt. The closure has a tamper indicating band connected to the skirt along a weakened line and has at least one flange extending upwardly and inwardly for engagement with a retaining bead on the container. The flange is hinged to the band along a first hinge at one end extending circumferentially of the band and along a second hinge at an angle to the first hinge. The other end of the flange circumferentially spaced with respect to the second hinge is free such that when the closure is applied to the container the flange flexes over the retaining bead on the container until the free edge of the flange extends beneath the retaining bead on the container and when the closure is rotated to remove the closure, the flange prevents the band from being removed and causes severing of the band along the weakened line.

  • Patent number: 4967920
    Abstract: This relates to a closure for containers wherein the closure is provided with a tamper indicating member. However, in lieu of the tamper indicating member being in the form of a continuous band which remains on the container neck after the closure is removed, the closure indicating member is of a limited circumferential extent filling a notch in a band extending from the closure skirt in lieu of a conventional tamper indicating band. This band does not interlock with the container. Only the tamper indicating member interlocks with the container, which container is provided with the normal tamper bead. The tamper indicating member is attached to the lower edge of the closure skirt by axial bridges and two opposite ends of the band by circumferential bridges. The bridges may all rupture when the closure is removed from the container with the tamper indicating member dropping out and leaving a readily observable notch in the band.

  • Patent number: 4951830
    Abstract: There is disclosed a snap-on closure which has upper and lower annular beads on the inside wall of a peripheral skirt with a tear band defined by at least one score line in the skirt, located between the annular beads. The closure has a center corking skirt that is downwardly dependent from its undersurface and this corking skirt has sufficiently thin side walls to flex. The corking skirt is spaced concentrically within the outer peripheral skirt of the closure and is spaced apart from the peripheral skirt by an annulus having a width which is slightly less than the width of the inner lip found on the neck finish of conventional bottles. This ensures that the corking skirt will resiliently engage the inside mouth of the bottle and be deflected thereby, thus forming a seal in the mouth of the bottle. The corking skirt can have reinforcement gussets that project radially inwardly from its side wall and depend from the undersurface of the top disk of the closure.
