A drinking container comprising:
- a flexible, hollow body having a neck;
- a closure member removably connected to the neck;
- a spout on the closure member;
- and
- a filter device connected to the spout within the body, the device including a hollow housing within the body, a filter within the body reciprocatingly movable within the housing, a passageway bypassing the filter and a movable valve member in the passageway which opens the passageway when the container is in an upright position with the spout on top, and blocks the passageway when the container is inverted from said upright position or is pressurized, the filter being within the valve member, the valve member being within the body and being reciprocatingly movable within the housings the passageway including a first opening between the spout and the housing, a space between the housing and the valve member and a second opening between the housing and the interior of the body.
