Publication number: 20040229763Abstract: A dishwashing kit contains a container with a foam-generating dispenser and a dishwashing composition within the container. The dishwashing composition contains a surfactant system and solvent. When the foam-generating dispenser is employed with the dishwashing composition, the foam-generating dispenser may generate a foam having a foam to weight ratio of greater than about 2 mL/g. When dispensed from the foam-generating dispenser, the dishwashing composition may also have an effective foaming dilution range of at least about 50% of the dilution range. When dispensed from the foam-generating dispenser, the dishwashing composition may also have an effective foaming dilution range which overlaps an effective solubilization dilution range. When dispensed from the foam-generating dispenser, the dishwashing kit may also generate a foam at a substantially different dishwashing composition to water dilution than the dilution at which the maximum volume of foam is formed according to a suds cylinder test.Type: ApplicationFiled: February 26, 2004Publication date: November 18, 2004Applicant: The Procter & Gamble CompanyInventors: Howard David Hutton, Richard Emil Hildebrand, Christopher Lamb, Kevin George Goodall, Ronald David Turner, Peter Robert Foley

Patent number: 6632493Abstract: Disclosed is a multi-layered plastic container (10) that substantially enhances product drainage and reduces product residual levels trapped in the container, especially for viscous liquid products, including oil-in-water emulsions, water-in-oil emulsions, polymeric gels, foams, surfactant mixtures, dispersions, colloidal dispersions, suspensions, polymer solutions, polymer melts, and products like catsup, mustard, syrup, etc. In a particularly preferred embodiment, the plastic container is made by blow-molding an extruded parison having an outer polyolefin layer (14), an intermediate adhesive layer (18), and an inner product-contacting layer (16) of a polyester material such as glycol-modified polyethylene terephthalate.Type: GrantFiled: August 3, 2001Date of Patent: October 14, 2003Assignee: The Procter & Gamble CompanyInventors: Richard Emil Hildebrand, IV, Robert Joseph Kissner, Pauline Cruz Zamora, Tomokazu Hattori, Hiroshi Furumichi

Patent number: 6468646Abstract: A multi-purpose sheet material comprising an absorbent layer and a cut-resistant material in contact with the absorbent layer. The cut-resistant material can comprise a cut-resistant support system, such as cut-resistant support element formed in the absorbent layer for example. The cut-resistant material may alternatively comprise cut-resistant particles, such as polymer particles having an average size of at least about 100 micrometers for example. Preferably, the sheet material exhibits an absorbent efficiency of at least about 0.2 and a slice resistance of at least about 30 kgf/cm, and more preferably an absorbent efficiency of at least about 1.0 and a slice resistance of at least about 40 kgf/cm. It is also preferred that sheet material exhibit a cut-resistance of at least about 30 kgf/cm, an absorbent efficiency of at least about 0.2, and a wet abrasion loss of less than about 400 mg per 100 revolutions.Type: GrantFiled: November 29, 2001Date of Patent: October 22, 2002Assignee: The Procter & Gamble CompanyInventors: John Kit Carson, John David Norcom, Richard Tweddell, III, Geneva Gail Otten, Steven Michael Schennum, Peter Worthington Hamilton, Richard Emil Hildebrand, IV, Kenneth Stephen McGuire

Patent number: 6451410Abstract: The present invention provides a sheet of crystallizable material, having opposed first and second surfaces, the sheet comprising: (a) a plurality of crystalline regions located in the first surface; and (b) an amorphous matrix surrounding and separating the crystalline regions from one another. The present invention also provides a method of making a flexible, cut resistant, and abrasion resistant sheet material, the method comprising the steps of: (a) providing a sheet of crystallizable amorphous material having opposed first and second surfaces; (b) crystallizing discrete regions of the first surface of the sheet of material, the discrete regions being separated from one another by a continuous amorphous matrix.Type: GrantFiled: July 20, 1999Date of Patent: September 17, 2002Assignee: The Procter & Gamble CompanyInventors: Kenneth Stephen McGuire, Peter Worthington Hamilton, Richard Tweddell, III, Richard Emil Hildebrand, IV, Geneva Gail Otten

Publication number: 20020061693Abstract: The present invention provides a liquid absorbent fibrous substrate having a plurality of discontinuous cells in which a second material is disposed. This second material is selected from a broad variety of organic or inorganic solids which may provide a reinforcing effect such that a sharp instrument is prevented from passing through the new composite structure. The reinforcing materials are disposed in a discontinuous array, in a cellular form in the fibrous substrate thus providing a path for liquids to be absorbed into said fibrous substrate, while said reinforcing materials provide resistance to penetration by sharp edged instruments. When disposed in this manner, flexibility is maintained since the reinforcing materials are not disposed in a continuous pattern. Preferably, the pattern disposed is free of linear regions that provide a continuous line of penetration for sharp edges.Type: ApplicationFiled: June 18, 1999Publication date: May 23, 2002Inventors: JOHN KIT CARSON, RICHARD EMIL HILDEBRAND, JAMES CAMERON HORNEY, JOHN DAVID NORCOM, GENEVA GAIL OTTEN

Patent number: 6383615Abstract: An absorbent and cut-resistant sheet having a cut-resistant material with a plurality of openings, and an absorbent material attached to the cut-resistant material. Preferably, the apertured cut-resistant material is in the form of sheet having a thickness of between about 0.005 inches and about 0.020 inches, and has an open area of less than about 50 percent. It is also preferred that the cut-resistant sheet have fold lines formed on a non-cutting surface, so as to make the material easily foldable and/or tearable. In addition, a stainable absorbent cover layer can be attached to a cutting surface of the cut-resistant sheet to provide an indication of where cutting has occurred, and to give the material a desirable appearance. A liquid impervious backing layer is also preferably attached to the absorbent material to resist the escape of fluid from the absorbent material. It is preferred that the cut-resistant sheet comprises a polymeric material.Type: GrantFiled: May 31, 2001Date of Patent: May 7, 2002Assignee: The Procter & Gamble CompanyInventors: Geneva Gail Otten, Albert Sylvester Crawford, II, Daniel James Rhoads, John David Norcom, Richard Tweddell, III, Peter Worthington Hamilton, Richard Emil Hildebrand, IV, Kenneth Stephen McGuire
