Abstract: A bottle cap includes a top and a skirt depending from the top, the skirt having a bottom edge, a locking bead radially extending inward from an interior of the skirt intermediate the top and the bottom edge, a tear tab extending downward from the bottom edge, a first tear line proximate the tear tab and extending upward along the skirt from the bottom edge across the locking bead and terminating at a terminus adjacent to or below the perimeter. The first tear line is substantially parallel to a longitudinal axis of the cap. The first tear line and the longitudinal axis define a radially extending plane P. The bottle cap also includes a second tear line proximate the tear tab and spaced from the first tear line. An upper portion of the second tear line extending through the plane P and between the terminus and the longitudinal axis. A method of using the bottle cap is also disclosed.

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: A closure for a container having a foil or membrane sealed opening. The closure includes a cap, a spout and a stem. The stem includes a downwardly extending piercing structure adapted for piercing the foil or membrane of the container upon rotation of the spout relative to the cap. The cap includes a cap top, a cap skirt depending from the cap top, an open sleeve and a stem guide. The open sleeve has an inwardly extending thread adapted to detachably engage the container. The open sleeve extends upwardly from the cap top. The stem guide extends along an internal surface of the sleeve. The spout rotatably engages the sleeve and includes a spout top having an aperture, an outer spout skirt and an inner skirt. The outer skirt depends from the spout top radially outward of the sleeve and rotatably engages the sleeve. The inner spout skirt depends from the spout top radially within the sleeve.

Abstract: Tamper-evidencing container and closure structures are provided for preventing or for signaling unauthorized access to packaging. These structures provide tamper-evidencing improvements that add to the security and reliability of packaged contents.

Abstract: 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.

Abstract: A closure includes a ribbed design wherein the ribs improve the ability to manually manipulate the closure and produce a distinctive aesthetic appearance. The new design allows improved manufacturing ability while reducing closure cost.

Abstract: A closure for sealing the opening of a container. The closure may include an angled plug. The container includes an external thread configuration and the closure includes an internal thread configuration which are adapted to pass over each other with one of the external and internal thread configurations having at least one thread lead and the other having at least twice as many thread leads. The closure includes an inwardly turned retaining rim extends at least partially upwardly. The retaining rim has an attachment boss and an upwardly extending line of weakness adjacent the attachment boss such that when the closure is removed from the container, the line of weakness tears allowing the tamper-evidencing band to remain with the closure upon removal from the container.

Abstract: A bottle cap (10) having a top (12) and a downwardly depending skirt (14). Skirt (14) includes an angled upper portion (20) and a generally cylindrical lower portion (22) with an exterior bead (24) thereon. Angled upper skirt portion (20) extends from a perimeter bead (23) down to a locking bead (34), which allows upper skirt (20) to transfer an application force from perimeter bead (23) radially to locking bead (34) in order to push the locking bead down around the upper crown (42) of a bottle neck (40). A method of applying the bottle cap is also disclosed.

Abstract: A tamper-evident, snap-on, screw-off closure is used with a specially shaped container neck. The neck has at least one first helical thread on an upper neck stretch portion, and at least one external ratchet tooth on a locking wall portion below the upper neck stretch portion. The closure has an upper skirt having at least one second helical thread mating with the first helical thread of the neck. A downward extending lower skirt portion includes an outer skirt portion and a shoulder extending inwardly from said outer skirt portion. A frangible section interconnects the shoulder and the upper skirt portion. At least one substantially vertical castle projection is formed upstanding from the shoulder, preventing upward deformation of the lower skirt portion without breaking the frangible section. The lower skirt portion has at least one internal ratchet tooth, and is formed with a line of weakness extending through the outer skirt portion and the shoulder.

Abstract: Two cap modifications are disclosed for use on water bottles to be installed in water dispensers. A central conical well in the top of the cap is formed with a scoreline. When the bottle is lowered into a dispenser, a probe of the dispenser enters the well and causes it to split along the scoreline. When the bottle is raised, the well substantially returns to initial condition, inhibiting spillage of any liquid remaining in the bottle.
