Patent number: 8157188Abstract: A container for a volatile liquid in a liquid dispensing device comprises a body and a neck extending from the body to define an opening. A retention structure is integral with the container body and is adapted to be releasably engaged with two opposing sidewalls of a housing of the dispensing device. The sidewalls are spaced apart in a first direction, and the retention structure is inhibits motion of the container in two opposing directions generally transverse to the first direction. The retention structure may be located on a side of the container body. A capillary member extends from inside the container to an exterior of the container. The volatile liquid migrates along the capillary member from the reservoir to the exterior of the container where it is evaporated from the surface of the capillary member by forced airflow generated by a motorized fan mounted in the housing.Type: GrantFiled: April 24, 2006Date of Patent: April 17, 2012Assignee: S.C. Johnson & Son, Inc.Inventors: Tyler D. Duston, Kishen Gohil, Colin W. Brown, Guy Naish, Mary Beth Adams, Ann E. Weeks

Patent number: 6560813Abstract: A mitt worn on a hand for cleaning. The mitt includes a section for the palm of the hand, a section for the fingers, and a compartment on either side of a central axis of the mitt for a thumb. The mitt is capable of being used on either the right or the left hand, and both sides of the mitt may be used without moving the mitt from one hand to the other. The mitt is formed using an electrostatically-charged material, a material capable of acquiring a triboelectric charge, or a material that is treated with a tackifying agent in order to optimize cleaning efficiency. Also disclosed is a method of forming a mitt for cleaning.Type: GrantFiled: December 21, 2000Date of Patent: May 13, 2003Assignee: S.C. Johnson & Son, Inc.Inventors: Colin W. Brown, Edward Francis, Jeffrey H. Fujimoto, Richard Graceffa, James R. Nielsen

Patent number: 5514302Abstract: An improved aqueous fabric cleaning shampoo composition contains a combination of (a) about 0.5-20% by weight of a fabric cleaning polymer which is a solid at 25.degree. C. and water dispersible or water soluble upon neuturalization with an alkaline compound such as a polymer of methacrylic acid/styrene/n-butyl acrylate, (b) about 0.1-10% by weight of a specific type of wax having a melting point of at least 50.degree. C. such as pressure-emulsified polyethylene wax and (c) about 0.05-5% by weight of a silicone betaine polymer in addition to an effective amount of at least one conventional anionic, nonionic, amphoteric or zwitterionic surfactant in water at a pH of from about 7 to about 10.5. Such a fabric cleaning shampoo composition not only provides good cleaning and conditioning to fabrics, particularly synthetic fibre fabrics, such as those used in carpets as well as to upholstery and pile fabrics, but also provides soil resistance to the fabric cleaned with such a composition.Type: GrantFiled: April 4, 1994Date of Patent: May 7, 1996Assignee: S.C.
