Abstract: A torque head assembly and method of capping effective to cap a variety of trigger spray cap bases or common caps to a spray bottle or container includes a drive roller mounted on a drive gear. The drive gear is in meshed gear communication with a plurality of train gears enclosed within a generally C-shaped driver housing wherein the a distal train gear engages a driven gear upon which a driven roller is mounted. An actuator allows the driver housing of torque head assembly to approach a variety of trigger spray cap bases or common caps within a plane generally horizontal thereto and at least partially co-planar therewith so as to capture the same between the dive roller and the driven roller and to thread mount the same onto the spray bottle or container.
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: 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: The inventive method for protecting from corrosion and scale deposit and restoring tubes of heat-exchanging equipment consists in applying a polymeric coating on the internal surface of tubes by gradually and rotationally moving an excessive volume of polymeric material therealong and in hardening said material. A polymeric compound having an at-rest viscosity ranging from 1000 to 1200 poises and a thixotropic viscosity reduction during the displacement thereof is used as a polymeric material. The inventive device for carrying out said method comprises a loading chamber (2), a connecting washer (12), a unit for progressively displacing the polymeric material provided with spaced rigid washers (4,5,6) fixed to a metallic rod (7), an elastic screw (8) having a conical shape whereby the conicity thereof ranges from 5 to 10° on the side which is opposite in relation to the connecting washer.

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: 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.

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: 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 has at least a first portion and a second portion. Each portion has a corresponding effective maximum diameter, wherein the effective maximum diameter of the first portion is less than the effective maximum diameter of the second portion.
