Patent

CA 2473948

The invention relates to a method of absorbing water vapour and malodour from a cavity, for example a drawer or wardrobe or the inside of a shoe. This is achieved by placement in the cavity of a package permeable to water vapour and retaining a particulate dehumidifying compound, a particulate odour-combating compound, and a filler comprising starch or a starch derivative or cellulose or a cellulose derivative, or which acts as a thickener or gelling agent for the water inside the package.

L'invention concerne un procédé d'absorption de vapeur d'eau et de mauvaises odeurs provenant d'une cavité, de type tiroir, penderie ou intérieur d'une chaussure. Cette opération est obtenue par placement dans la cavité d'un conditionnement perméable à la vapeur d'eau et retenant un composé particulaire de déshumidification, un composé particulaire de lutte contre les mauvaises odeurs, et un matériau de remplissage qui comprend de l'amidon ou un dérivé de celui-ci, ou de la cellulose ou un dérivé de celle-ci, ou qui fait office d'épaississant ou d'agent gélifiant destiné à l'eau contenue dans ledit conditionnement.
