摘要： A self-sealing valve (2) for a liquid dispenser, comprising an envelope (3) of flexible sheet material having opposed inlet and outlet portions and an intermediate portion (6) between the inlet and outlet portions, which intermediate portion (6) comprises a spaced pair of transverse folds (4, 5) in the envelope (3) to restrict or prevent flow of fluent material, e.g., liquid, between the inlet and outlet portions, the arrangement being such that fluent material flow across the intermediate portion (6) can be induced by distortion of the intermediate portion (6), e.g., the application of pressure to the envelope (3) upstream of the intermediate portion, thus causing the seal created by the transverse folds (4, 5) to open to allow the material to pass. A liquids dispensing sachet (1) having a self sealing valve (2) as described above and a wall mounted dispenser (17) for liquids including such a sachet.
