Patent number: 8857195Abstract: An absorbent adapted to be used in a spray can charged with a liquefied gas, which exhibits excellent absorbing performance and excellent liquid retention. The absorbent is composed of an assembly of pulverized cellulose fibers that includes at least 45 mass % of fine cellulose fibers having a fiber length of 0.35 mm or less. The absorbent is formed into a sheet-shaped or a columnar configuration, or a surface sheet is laminated on a surface of the absorbent. The absorbent composed of 70 through 90 mass % of cellulose fibers that include 45 mass % or more of fine cellulose fibers having a fiber length of 0.35 mm or less, and 5 through 30 mass % of a fusion-bondable resin exhibits good formability.Type: GrantFiled: December 25, 2007Date of Patent: October 14, 2014Assignees: NKK Co., Ltd., Toyota Tsusho CorporationInventors: Toshifumi Hatanaka, Masaki Okada, Kiyotaka Miyata, Teruo Miura

Patent number: 8822552Abstract: A spray can product capable of preventing leakage where used or stored in a tilted or an inverted position, and keeping good safety and liquid retention even where a flammable liquefied gas is used. The spray can product is formed by filling a spray can having an ejection opening with a liquefied gas and an absorbing body for retaining liquid, and the absorbing body is composed of an assembly of cellulose fibers containing at least 45 mass % of fine cellulose fibers having a fiber length of 0.35 mm or less. The absorbing body compressed into a block-shaped configuration corresponding to that of the spray can is accommodated within the spray can while defining a space on the side of an ejection opening, and a lid-like member is provided between the space and the absorbing body to protect a surface of the absorbing body in a gas permeable manner.Type: GrantFiled: November 2, 2009Date of Patent: September 2, 2014Assignees: NKK Co., Ltd., Showa Denko Gas Products Co., Ltd., Japan Petroleum Exploration Co., Ltd.Inventors: Toshifumi Hatanaka, Masaki Okada, Kiyotaka Miyata, Teruo Miura
