Patent number: 6562016Abstract: A paper diaper using an water-absorbing polymer is superior in absorbency/water-retaining performance to a cloth diaper, but it has the drawback that it generates garbage and is expensive. An water-absorbing pad is formed by allowing an water-absorbing polymer which is dispersed, dissolved or melted or the crosslinks of which are broken in an electrolytic aqueous solution to be retained by a water soluble material. An water-absorbing product is produced by interposing the water-absorbing pad thus formed between sheets of cloth or other materials. The water-absorbing pad secured within the product is dissolved when washed with an electrolytic aqueous solution, and the product itself is reusable.Type: GrantFiled: April 17, 2001Date of Patent: May 13, 2003Assignee: Shinkai Co., Ltd.Inventor: Yoichi Shinkai

Publication number: 20020128615Abstract: The present invention relates to absorbent articles including non-aqueous compositions for protecting the barrier function of the skin. The compositions can be applied to the bodyfacing surfaces of absorbent articles so that the compositions come into contact with the skin. The compositions of the invention have improved stability on the bodyfacing surfaces after processing. The compositions of the invention provide several benefits including prevention and alleviation of skin irritations associated with the use of absorbent articles. The compositions can include emollients, viscosity enhancers and anionic polymers.Type: ApplicationFiled: December 22, 2000Publication date: September 12, 2002Inventors: David John Tyrrell, Chantel Spring Buhrow, David Roland Otts, Duane Gerard Krzysik, Earl David Brock, James Louis Cahall, Samuel Qcheng Lin

Publication number: 20020128621Abstract: The present invention relates to absorbent articles including skin care compositions. The skin care compositions of the invention are stable on the bodyside liners of absorbent articles despite not containing an immobilizing agent. Surprisingly, the skin care compositions of the invention even demonstrate less migration away from the bodyside liner than do other compositions that contain so-called “immobilizing agents”. The compositions of the invention possess physical properties, such as melting points, viscosities and hardnesses, comparable to compositions containing immobilizing agents, making them suitable for use on absorbent articles.Type: ApplicationFiled: December 21, 2001Publication date: September 12, 2002Inventors: Benjamin Joseph Kruchoski, Michael Brent Kottek, Duane Gerard Krzysik, Corey Thomas Cunningham, Lewis Preole Orchard

Publication number: 20020128616Abstract: A liquid reception device as a component, for example, of a personal care product such as a disposable diaper, an incontinent garment, or for other applications such as, for example, an industrial soaker pad or the like. The device includes liquid activated means to move a liquid insult from a target zone to a peripheral zone. The liquid activated transport means operated mechanically by suction created by compression or vacuum or by physical movement of a liquid container from the target zone to the peripheral zone. The disclosed device provides increased use of available liquid handling capacity.Type: ApplicationFiled: April 12, 2002Publication date: September 12, 2002Inventors: Michael Tod Morman, Bryan David Haynes, Thomas Harold Roessler
