Cap Patents (Class 215/28)
  • Patent number: 8308004
    Abstract: A dispensing package includes a container having a neck finish with an axis, a non-circular cross section in a plane perpendicular to the axis, and at least one circumferentially extending external engagement element on the neck finish. A closure has a wall received over the container neck finish. The wall has a non-circular cross section corresponding to the non-circular cross section of the neck finish and at least one internal circumferentially extending engagement element in engagement with the external engagement element on the neck finish. The internal and/or external circumferentially extending engagement element has a shallow lead-in angle to enable press-fit of the closure onto the container neck finish and a steep back angle to retard removal of the closure from the neck finish. Rotation of the closure on the neck finish is prevented by the non-circular cross sections of the neck finish and the closure wall.

  • Patent number: 6908013
    Abstract: There is disclosed a tamper-evident device for a closure assembly adapted to be applied to a mouth of a container, for example, a neck of a bottle. There has been identified a need for an improved tamper-evident device which does not have any parts which are removed upon initial opening and which are liable to be reattached by counterfeits or the like. Accordingly the present invention provides a tamper-evident device comprising a sleeve member which comprises a first portion associated with a second portion by a frangible portion therebetween, and wherein said first portion is adapted to be applied to a mouth and neck portion of a container, and said second portion is associated with a container closure member, and wherein an initial container opening operation causes said frangible portion to fracture or break such that when the container is reclosed said first and second portions are located in a spaced apart relationship to one another.

  • Patent number: 6053375
    Abstract: A non-resealable, snap-fitted closure comprises a closure, a drop ring and a container. The closure has a sleeve with a sleeve snap. The drop ring has an internal snap and an external snap wherein the internal snap engages the sleeve snap of the closure when the closure engages the drop ring. The container has a neck and a neck snap, wherein the neck snap and the internal snap of the drop ring engage when the closure and the drop ring engage the neck. The neck snap of the neck and the internal snap of the drop ring are an order of magnitude stronger than the sleeve snap of the sleeve and the external snap of the drop ring. When the closure is removed from the neck, the drop ring remains attached to the neck and is free to move vertically up and down along the neck, thereby preventing reattachment of the closure to the container.

  • Patent number: 5690241
    Abstract: A removal resistant closure cap for a container having a standard threaded neck is disclosed. The cap does not have a thread complementary to the container neck thread but has an inwardly projecting circumferential bead with an intersecting projection extending downwardly from the bead at the helix angle of the container neck thread. When the container neck is engaged by the cap with a threading rotation, the cap projection will engage the container neck thread, and the cap bead will snap over the container neck thread, permanently retaining in the cap on the container neck.

  • Patent number: 5096077
    Abstract: A stoppering device non-removably attached to the flanged neck of a container has a base (8) projecting beyond the neck of the container, with at least two arcuate surface sections extending from the base and disposed along a circle having a diameter slightly greater than that of the outer surface of the flanged neck (5). Each arcuate surface section (16) is extended on at least one of its sides in the circumferential direction by a locking foot (17). Each foot is integral with the arcuate surface at the end of the section opposite to the base (8) and is inclined inward from the end integral with the arcuate surface section (16) to a free end of the foot located toward the base (8). Each foot abuts the flanged neck (5) and holds the stoppering device securely onto the container.

  • Patent number: 4540100
    Abstract: A device for attaching a fitment to an open mouth container and for tamper-evident sealing of the fitment with the fitment attached thereto. The device includes a closure portion having a first skirt portion adapted for rolling a thread to engage a cooperating thread on the fitment. Other skirt portions are adapted for rolling such portions into engagement with the fitment and the container to firmly attach the fitment to the container, and a fracturable line of weakening is provided between the first skirt portion and the other skirt portions to provide evidence that the container has been opened upon a first unthreading of the closure.
