A movable seal for interfacing between a first surface and a second surface includes a floating portion attached to a non-floating portion by a flexible coupling portion, wherein the non-floating portion is coupled to the first surface by nesting in a groove on the first surface, and wherein the non-floating portion forms a seal between the first and second surfaces when the first surface moves relative to the second surface in a first direction, and wherein the non-floating portion does not form a seal between the first and second surfaces when the first surface moves relative to the second surface in a second opposite direction.

Filtration container assemblies and methods

Water bottle cap

Compact drink cap for filtration

A self-back flushing filtration assembly includes an inner container, an outer container, and a filter cartridge. The inner container is configured to receive treated water by way of a filter cartridge. The outer container is configured to hold untreated water and sleeve the filter cartridge and the inner container. The inner container and the filter cartridge are moveably positioned within the outer container to compress and draw the untreated water through filter media within the filter cartridge by way of a filter cap. The filter cap is movably positioned within a cavity of the outer container to draw treated water from the inner container through the filter media of the filter cartridge.
