  • Patent number: 8096099
    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.

  • Patent number: 7836844
    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.

  • Patent number: 7832579
    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.

  • Patent number: 7810681
    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.
