20110114594 | SCALLOP CAP CLOSURES - The present invention is directed to a closure for a container. In one of the embodiments provided herein, the closure is provided with a roof portion, a shoulder portion that merges with the roof portion, and a skirt portion depending from the shoulder portion. Provided on the shoulder portion are recessed regions and full-depth regions. The recessed regions and full-depth regions alternate around the shoulder portion and are provided for improving a number of manufacturing, costs, and structural factors. In another embodiment provided herein, the closure is provided with a cylindrical skirt depending substantially from a roof portion, the cylindrical skirt having an inner wall with a plurality of narrow, elongated, vertical stand-off ribs thereon, the ribs having an upper edge below a tension ring and a lower edge below the upper edge and an elongated length causing the lower edge to be positioned about 50% to 25% above a bottom edge defined by the cylindrical skirt and measured against the entire length of the cylindrical skirt. | 05-19-2011 |
20110100948 | DESIGN AND MANUFACTURE OF REMOVABLE MEMBRANE SEALING COMPONENTS FOR CONSUMER PACKAGING - 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. | 05-05-2011 |
20110011821 | DESIGN AND MANUFACTURE OF REMOVABLE MEMBRANE SEALING COMPONENTS FOR CONSUMER PACKAGING - 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. | 01-20-2011 |
20100294812 | INTERNAL CONTAINER BORE MOUNT FITMENT - 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. | 11-25-2010 |
20100230374 | TAPERED THREAD STRUCTURE - In one embodiment there is provided a novel container neck finish having a substantially cylindrical exterior wall surface surrounding an orifice defined in the container and a thread structure positioned about the exterior wall surface. The thread structure in one aspect has at least a first portion, a second portion positioned substantially axially below the first portion, and a third portion positioned substantially axially below the second portion. The first, second, and third portions, being inclined with respect to the other portions provide a screw on neck finish. The effective maximum diameter of the first portion is less than the effective maximum diameter of the second portion to define a first to second separation distance. And the effective maximum diameter of the second portion is less than the effective maximum diameter of the third portion to define a second to third separation distance. | 09-16-2010 |
20100140268 | DISPENSING CLOSURE WITH REMOVABLE MEMBRANE - In an embodiment of the invention, there is provided a closure for a container having a container opening. The closure includes lower and upper separable component closure pieces secured to one another. The lower component includes a removable membrane that may be removed by the opening of a top contained in the upper component. The top is further permitted to be removed from the closure without detaching the lower component from the container. | 06-10-2010 |
20100140266 | DISPENSING CLOSURE WITH HINGED LID - In an embodiment of the present invention there is provided a closure for attachment to a container. The closure includes a base having an orifice and a skirt depending from the base. A lid is provided and is joined to the base through an integral hinge. The lid has a plug depending from an underside section of the lid. The plug is preferably sized to fit within the orifice when the lid is closed. The closure further includes rails projecting upwardly from a top portion of the base and rails projecting downwardly from the underside section of the lid. The rails further include at least one bead projecting (radially inwardly from each of the first rails) and (radially outwardly from each of the second rails). The beads are positioned to interfere with each other to form a snap fit when the lid is closed. | 06-10-2010 |
20100012687 | INTERNAL CONTAINER BORE MOUNT FITMENT - 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. | 01-21-2010 |
20080272084 | DESIGN AND MANUFACTURE OF REMOVABLE MEMBRANE SEALING COMPONENTS FOR CONSUMER PACKAGING - 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. | 11-06-2008 |
