Title (EN) PRESSURE GENERATING SYSTEM FOR A DISPOSABLE CONTAINER
(FR) SYSTEME GENERATEUR DE PRESSION POUR UN RECIPIENT JETABLE
Abstract:
(EN) A self-generating gas pressure apparatus such as an expandable closed pouch (2) is placed within a container (60) from which a fluid (68) therein is to be dispensed under pressure. The apparatus has a plurality of internal compartments (14, 16, 22, 24) formed by pressure-rupturable seals (20) and containing respective chemical compounds (30, 32, 34) which when mixed upon adjacent-compartment seal rupture produce a gas. At least one of two adjacently-housed chemical compounds has in addition thereto a nucleating agent such as diatomaceous earth which acts to more rapidly force gas generated in the reaction of the adjacently-housed chemical compounds out of solution and thereby provide an operative pressure to the apparatus more quickly.
(FR) Un appareil à pression de gaz auto-générative, tel qu'une poche fermée expansible (2) est placé, dans un récipient (60) qui contient un fluide (68) et d'où ce fluide doit être distribué sous pression. L'appareil comporte plusieurs compartiments intérieurs (14, 16, 22, 24) qui sont formés par des joints d'étanchéité (20) cassables sous pression et qui contiennent des composés chimiques respectifs (30, 32, 34), lesquels produisent un gaz lorsqu'ils sont mélangés lors de la rupture des joints d'étanchéité de compartiments adjacents. Au moins l'un des composés chimiques logés adjacents contient en outre un agent de nucléation, tel que de la terre diatomacée, qui agit de façon à extraire plus rapidement de la solution le gaz produit dans la réaction des composés chimiques logés adjacents et à fournir ainsi plus rapidement une pression opérationnelle à l'appareil.
