| 摘要 |
The invention concerns a system for dispensing and recovering liquids designed to be arranged in a rigid container, comprising a liquid dispensing tank (16) and a tank (17) for recovering liquid after use, each tank (16, 17) including an envelope (18). Each envelope (18) includes two similar walls (19, 20) comprising each an outer surface and a peripheral edge (23). Each envelope (18) has a retracted configuration wherein said walls (19, 20) are deployed one proximate the other and in an inflated configuration wherein said outer surfaces of each said wall (19, 20) are convex. At least one envelope (18) is capable, in its inflated configuration, to be nested in the other envelope (18) in its retracted configuration.
