  • Patent number: 5573700
    Abstract: An aqueous liquid detergent composition is provided for cleaning a hard surface and for repelling insects therefrom comprising a detersive proportion of a surface active detergent compound, an effective amount of an insect repellent material which is sufficient to repel insect from the hard surface after application of the detergent composition thereto, the liquid detergent composition being substantially free of a liquid hydrocarbon.
    Type: Grant
    Filed: May 15, 1995
    Date of Patent: November 12, 1996
    Assignee: Colgate-Palmolive Co.
    Inventors: Robert J. Steltenkamp, John H. Puckhaber, Jr., Daniel Colodney, Thomas C. Hendrickson
  • Patent number: 5569411
    Abstract: An aqueous liquid detergent composition is provided for cleaning a hard surface and for repelling insects therefrom comprising a detersive proportion of a surface active detergent compound, an effective amount of at least one of certain defined insect repellent materials which is sufficient to repel insect from the hard surface after application of the detergent composition thereto, the liquid detergent composition being substantially free of a liquid hydrocarbon.
    Type: Grant

  • Patent number: 4547237
    Abstract: A drawstring is mounted near the open mouth of a plastic bag by a pressure sensitive tape that freely laterally encloses the drawstring except for projecting free ends, the tape being formed or treated so as to be non-sticky with respect to the drawstring. A high speed production method of making the bags comprises the steps of laying a continuous length of drawstring material across a series of spaced bags, applying strips of pressure sensitive tape to each bag to freely laterally enclose the drawstring length there and severing the drawstring length between bags.
    Type: Grant
    Filed: September 7, 1979
    Date of Patent: October 15, 1985
    Assignee: Colgate-Palmolive Company
    Inventor: Thomas C. Hendrickson
  • Patent number: 4340558
    Abstract: Process for forming a scrim-reinforced film wherein a molten, film-forming plastic, such as polyethylene, in a high state of fluidity is fed onto an unsupported scrim and solidified by cooling to produce a scrim at least substantially completely enclosed and surrounded by the plastic. The film, thus produced, can be formed into a high strength bag container by a folding and cutting operation utilizing hot knife means capable of fusing and thus sealing the plastic. In a preferred embodiment, the plastic is extruded onto the scrim.
    Type: Grant

  • Patent number: 4254139
    Abstract: Reusable article of unitary construction for dispensing conditioner for fibrous materials in an automatic laundry dryer and/or washer or similar container for fibrous materials, comprising a first layer of magnetized, substantially form retaining sheet material such as soft rubber, adapted to forcibly, magnetically engage an inner metal surface of said dryer and/or washer in form-retaining relationship therewith and secured thereto in overlying relationship a second layer of sorptive material, e.g., foam plastic, natural or synthetic sponge for receiving the conditioner.

  • Patent number: 4087577
    Abstract: Process for forming a scrim-reinforced film wherein a molten, film-forming plastic, such as polyethylene, in a high state of fluidity is fed onto an unsupported scrim and solidified by cooling to produce a scrim at least substantially completely enclosed and surrounded by the plastic. The film, thus produced, can be formed into a high strength bag container by a folding and cutting operation utilizing hot knife means capable of fusing and thus sealing the plastic. In a preferred embodiment, the plastic is extruded onto the scrim and is subsequently heat shrunk to cause the scrim fibers to buckle and give the appearance and feel as well as the strength of a reinforced material.
