Patent number: 5769833Abstract: The present invention relates to an absorbent article and preferably a diaper or incontinent device having perfume zones disposed on the backsheet outer surface or on a backing member attached to the backsheet outer surface. The perfume zones generally comprise a binder having release agents of one or more types dispersed therethrough. Additionally, the perfume zones contain pull-strips attached to the binder which, when detached from the binder, will cause perfume to be released from the release agents either by shearing of the agents or diffusion as a result of uncovering the binder. The perfume provides the functions of either masking and/or absorbing malodors and are released via fragrance burst, and/or diffusion over time. Furthermore, perfume is released either at attachment of the article about a wearer, at removal of the article from about a wearer and/or during sustained wear of the article about a wearer.Type: GrantFiled: December 12, 1996Date of Patent: June 23, 1998Inventor: Margaret Henderson Hasse

Patent number: 5769832Abstract: The present invention relates to an absorbent article and preferably a diaper or incontinent device having perfume-filled release agents, preferably being perfume-filled microcapsules, disposed on the diaper fastening system. The encapsulated agents and/or odor masking agents are released subsequent to the removal of the article from about the wearer, i.e., as the fastening system is disconnected, the microcapsules burst, thereby releasing the agents to the air containing the malodor constituents.Type: GrantFiled: April 17, 1996Date of Patent: June 23, 1998Inventor: Margaret Henderson Hasse

Patent number: 5733272Abstract: The present invention comprises compositions and articles such as catamenials, diapers, pantiliners, adult incontinence garments, and underarm shields which minimize odor caused by body fluids and which provide a pleasant scent signal to indicate that the odor is being removed. This scent signal, provided by cyclodextrin/perfume inclusion complexes and/or matrix perfume microcapsules, assures the wearer that the product is working.Type: GrantFiled: June 6, 1995Date of Patent: March 31, 1998Assignee: The Procter & Gamble CompanyInventors: Gordon Francis Brunner, Toan Trinh, Thomas Alfred Inglin

Patent number: 5700476Abstract: The invention provides wound dressing and/or implant materials comprising a matrix structure of sponge, at least one substructure and at least one pharmacologically active agent, wherein both the matrix structure and the substructure are formed from bioabsorbable biopolymer materials. The substructure may, for example, comprise biopolymer films, flakes, fibres or microspheres embedded in the matrix structure of sponge. The pharmacologically active agent may comprise antiseptics, antibiotics, analgesics. One or more such active agents may be incorporated separately into the matrix and/or the substructure so as to achieve controlled or phasic release of the active agents into the wound.Type: GrantFiled: February 24, 1995Date of Patent: December 23, 1997Assignee: Johnson & Johnson Medical, Inc.Inventors: Arthur L. Rosenthal, Nicholas D. Light, Carla A. Haynes
