UNIT DOSE FLEXIBLE CONTAINER

摘要

A pliable single use liquid container and dispensing device for delivery of liquids across a broad range of viscosities is provided with the container being formed of opposed pliable sheets (3, 5), a first seal (7) joining the first and second sheets (3, 5) and partially defining a liquid-containing chamber (9), a second seal (13) joining the first and second sheets and partially defining a pressure relieving chamber (15) adjacent to the liquid-containing chamber (9), a boundary seal (17) joining the first and second sheets (3, 5) between the liquid containing chamber (9) and the pressure relieving chamber (15), the boundary seal (17) being lighter than the first and second seals (7, 13) so that upon application of pressure to the liquid in the liquid-containing chamber (9) the fluid transfer region seal opens to permit the liquid to flow from the liquid-containing chamber into the pressure relieving chamber (15), a sealed outlet (27) adapted for fluid communication with the pressure relieving chamber for flow of the liquid from the pressure relieving chamber (15), the outlet seal (33) being adapted to open upon application of fluid pressure from the pressure relieving chamber (15) for dispensing the liquid from liquid container and prevent spilling and splashing of the liquid prior to delivery.
