Abstract: A lightweight neck finish includes a retaining structure that interacts with a tamper band to cause frangible connectors between the tamper band and closure to break upon initial removal of the closure from the neck finish. An upper retention portion of the retaining structure has a profile with a reduced footprint as compared to a conventional retaining structure. A lower support portion of the retaining structure has an outermost diameter similar in size to an outermost diameter of a conventional retaining structure. However, the lower support of the lightweight neck finish is formed with one or more circumferentially extending slots and/or one or more vertical slots. The reduced footprint of the retention portion and the slots of the support portion minimize the amount of material, weight, and time and cost required to make the lightweight neck finish, while providing for increased tamper evidence visibility as compared to conventional neck finishes.

Abstract: A closure that remains coupled to a container after the upper portion of the closure has been rotatably removed from the container. The closure may include an attachment channel, which includes alternating segments of linear openings and frangible connections. The attachment channel may also include two hinge bridges that remain unbroken when one or more of the frangible connections are broken.

Abstract: A closure having several plug seals extending from a lower surface of the top panel of the closure is provided. The outer surface of the first plug interfaces against the inner surface of the container inlet, the bottom surface of the second plug interfaces against the top surface of the container inlet, and the inner surface of the third plug interfaces against the outer surface of the container inlet. The second and third plugs have thinner and thicker arcs, the thinner arcs being configured to more easily relieve internal pressure from the container. The bottom of the closure includes an improved design for a J-band in which the J-band has a width that increases as the J-band extends from the tamper band.

Abstract: A closure having an angled plug seal extending from a lower surface of the top panel of the closure is provided. The outer surface of the plug is formed having an upper portion, a middle portion, a transition section and a lower portion. The upper portion, middle portion and lower portion each extend along planes that extend at differing angles relative to the vertical axis about which the closure is centered. The configuration of the outer surface of the plug allows a single closure to interchangeably be used to fluidly seal containers having any number of different container neck finish configurations.

Abstract: A closure for a container is provided with a top portion and a skirt depending from an outer periphery of the top portion. A generally circular rim extends downwards from the lower surface of the top portion. A liner is attached to the closure between an outer surface of the rim and an inner surface of the skirt. The liner is configured to provide a fluid tight seal for containers having varied neck dimensions and/or profiles. One or more projections extend into a space formed between the lower surface of the top portion, an inner surface of the skirt, and an outer surface of the rim, with the liner enveloping and being supported in the closure by the one or more projections.

Abstract: A light weight, reinforced, molded, plastic closure is provided. The closure includes an end wall and a sidewall. A portion of the end has been substantially thinned such that the portion of the end wall is substantially thinner than other portions of the closure such as the sidewall or outer peripheral end wall area. The closure may also include interrupted threads that also contributes to the low weight of the closure.

Abstract: A closure for a container having a container opening is provided herein. The closure includes an annular top having an inner skirt depending downwardly from an inner perimeter of the annular top and having an outer skirt depending downwardly from an outer perimeter of the annular top. An annular bottom extends radially inward from the inner skirt, and the annular bottom has defined thereon a dispensing aperture positioned adjacent to the container opening when the closure is mounted to the container. A sealing member is formed to the annular bottom for closing the dispensing aperture. The outer skirt optionally includes a hingedly flexible flap having one or more gussets dimensioned to cooperate with the anti-rotation structure of a neck finish.

Abstract: A composite lined closure for use with a container having a container neck crown includes a top having a periphery and an underside, a skirt depending downward from the periphery, the skirt including an inner surface and a locking bead radially extending inward from the skirt, and a resilient seal liner extending along the underside and along the inner surface above the sealing bead. Preferably, the liner is formed of an elastomeric material. A method of using the composite lined closure is also described.

Abstract: In an embodiment of the invention there is provided a membrane fitment designed and sized to be inserted into the orifice defined by a container. Retention structure on the fitment cooperates with complimentary structure on the internal wall of the container orifice to secure the fitment within the orifice such that the combination forms an excellent primary seal. Tamper evidence is offered by the normal requirement for initial membrane removal. Novel designs for the membrane, its associated pull ring, and the frangible removal structure are taught in various embodiments. The novel designs may promote facile initial removal suitable for a child. In addition, the novel designs avoid the potential hazards presented by prior art membranes.
