Abstract: The invention relates to nozzle tips including a nozzle body and a tip portion, configured to minimize the accumulation of a resin on the nozzle tip as it is dispensed through the nozzle tip. The nozzle tip can contain a central flow channel and an internal portion that branches and guides the resin into multiple exiting flow channels that define tangential pathways to the outer surface of the nozzle tip. The nozzle tip can include grooves that define extended, sharply angled flow paths for the resin. Nozzle tips can have a neck portion separating a nozzle body and a tip end of the nozzle tip; here, a doughnut-shaped space located around the neck portion can be defined by the base of the nozzle, the crown of the nozzle, and the neck portion, for encouraging turbulent flow of the resin to scour the nozzle tip during dispensing.

Abstract: The invention provides an assembly for dispensing portioned amounts of materials from a container, while keeping the undispensed portions stored within the container, and displaying the dispensed portions for consumption. The cap assembly includes a body member which can reversibly engage the container, and a cap member that transfers predetermined volumes of articles from the interior of a container to a serving vessel that is accessible by an individual consumer, while leaving the remainder of the articles within the container and unavailable to a consumer. The relative position of the body and cap members block or unblock a passageway for dispensing articles through a mouth of the container. The cap member can be used multiple times to dispense additional volumes of articles from the container as desired.

Abstract: A two-piece tamper-evident band assembly for use with a container and closure combination, where the container has a peripheral collar and the closure has a skirt, is shown. The tamper-evident band assembly includes a breakaway band frangibly connected to a staying ring. The staying ring has decreased flexibility where it connects to the container and closure combination, which prevents the assembly from deforming in a manner that will cause the assembly to fail to indicate that the container has been opened. The tamper-evident band assembly also indicates whether the container has been compromised without requiring modification of the container or the closure and can be applied to existing container and closure combinations that lack a tamper-evident system, allowing the assembly to be used with a variety of container and closure combinations.

Abstract: A tamper-evident closure is disclosed, having a skirt, threads on an interior of the skirt, and a tamper-evident band secured to the closure body by frangible bridges along a circumferential lower surface of the closure. The band and the closure have a plurality of equidistant vertical upper and lower teeth along an interior wall. Further the subject invention includes a mandrel for use in cutting slits in tamper-evident closures. The mandrel is supported for rotational movement within a closure, and comprises a disc with a circumferential surface with a plurality of equidistant slots for meshing with complementary teeth on the interior surface of the closure.

Abstract: An open top closure for use in conjunction with a liner. The closure has sidewalls and the upper portion of the closure is open, with at least one rib positioned a spaced distance above the plane of the liner. When in place on a container, the rib serves to limit the travel of the liner upward as it expands after the hot-fill of a product. The open upper portion of the closure permits any accumulated moisture to be blown off after the hot-fill is cooled.

Abstract: A two-part closure for use in conjunction with a liner. An upper part of the closure is substantially plate like and clips or snaps onto the lower part of the closure. The lower part of the closure includes recessed vents which allow air and/or moisture to escape from beneath the closure. The lowest part of the closure has sidewalls with interior threads or a snap-on rib, as desired. The upper portion of the lower part is open, with crossing ribs positioned a spaced distance above the sealing lip for the lower part.

Abstract: A heat-sealable, plastic bottle with an internal scraper and an inner seal is described. More particularly, the present application relates to a heat-sealable, plastic bottle having an opening with an internal scraper chord that is less than or equal to the diameter of the circular opening, an inner seal, and a cap.

Abstract: A system with rotatable levers spaced and positioned to alternately retain or release components from a plurality of lanes simultaneously into slots of a component receiving mechanism. The levers may be differently sized and shaped to hold back certain components at different positions than others, or the levers may be attached to a rotatable member at varying angles to one another to accomplish such varying holdback patterns. Alternatively, a cam and pin arrangement may be utilized.

Abstract: A tamper-evident closure and container combination identifies a compromised seal when a severable ring has been detached from a closure upon a first opening of the container. Successful detachment of the severable ring is improved whereby a lower neck portion of a container is angled or arced downwardly and outwardly from a point immediately adjacent an annular ring.

Abstract: A method of applying a liner to a container mouth in a hot-fill operation, said method comprising the steps of: placing the liner over a mouth sealing surface of the container; heating the liner by induction or conduction; and cooling the liner immediately thereafter while biasing the liner against the mouth sealing surface for a sufficient length of time to permit curing and sealing of the liner to the mouth sealing surface.

Abstract: A closure and container combination where the closure has flanges that define a channel capable of receiving a portion of the neck of a container and forming a surface seal therewith.

Abstract: A container closure comprising a top wall portion and a skirt portion depending from the top wall portion is provided. The skirt portion can include corrugation on an interior and exterior thereof, and the corrugation can reduce the weight of the container closure and provide strength of the skirt portion.

Abstract: A two-piece closure and tamper evident band assembly for use with a container neck having a peripheral bead is shown. The closure includes a top having a depending skirt. The skirt includes a break-away band frangibly connected to a bottom periphery of the skirt. The tamper evident band includes means for tearing and a lower ledge extending from a lower periphery of the band. The break-away band is positioned above the lower ledge. The closure and tamper evident band assembly is inserted onto the container neck, and when the closure is removed, the peripheral bead prevents the lower ledge and the tamper evident band from moving upward. As the closure moves up the container neck, the means for tearing tears the frangible connectors so that the break-away band and the tamper evident band remain positioned on the container.
