A container (10) for liquids is provided, in which pressurisation of the container is used to force the liquid through one or more membranes to an output. The membranes are disposed across substantially an entire length of the container, and pass liquid in preference to air. As a result, the liquid may be extracted from the container in any orientation. A particular use for this kind of container is as a portable water bottle containing a filter (20). |
