Abstract
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.
Claims20
A filtration container assembly, comprising:
- an outer container having and a first open end and a second closed end and defining an inner cavity;
- a plunging assembly configured to be received at least partially within the inner cavity of the outer container, wherein the plunging assembly includes an inner sleeve having a first end and a second end and an outer wall, the plunging assembly defining an inner bore, and a filtration assembly in fluid communication with the inner bore, wherein the plunging assembly is configured to filter a liquid in the outer container as the liquid moves from the inner cavity of the outer container through the filtration assembly to the inner bore of the plunging assembly;
- and
- a valve coupled to the filtration assembly.
A filtration container assembly, comprising:
- an outer container having and a first open end and a second closed end and defining an inner cavity;
- an inner sleeve configured to be received at least partially within the inner cavity of the outer container, wherein the inner sleeve includes a first end and a second end and an outer wall, wherein the inner sleeve defines an inner bore;
- a filtration assembly coupled to the second end of the inner sleeve, wherein the filtration assembly includes a housing having a fluid inlet and a fluid outlet, and wherein the filtration assembly is configured to filter a liquid in the outer container as the liquid moves from the inner cavity of the outer container through the fluid inlet and to the fluid outlet;
- and
- a valve coupled to the filtration assembly, wherein the valve is movable between first and second positions, wherein in the first position, the fluid outlet is in fluid communication with the inner bore, and wherein in the second position, the fluid outlet is closed to the inner bore.
A method of filtering a liquid, comprising:
- filling an outer container at least partially with the liquid, wherein the outer container includes a first open end and a second closed end and defining an inner cavity for receiving the liquid;
- inserting a plunging assembly at least partially into the inner cavity of the outer container, wherein the plunging assembly includes an inner sleeve having a first end and a second end and an outer wall, the plunging assembly defining an inner bore, wherein the plunging assembly includes a filtration assembly in fluid communication with the inner bore and a valve coupled to the filtration assembly;
- and
- pressing the plunging assembly into the inner cavity of the outer container such that liquid moves from the inner cavity of the outer container through the filtration assembly and valve and to the inner bore of the plunging assembly.
