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.
Claims24
A filtration container assembly, the assembly comprising:
- an outer container having a first open end and a second closed end and defining an inner cavity;
- and
- a plunging assembly having a longitudinal axis and being 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, a filtration assembly in fluid communication with the inner bore, and a seal movable between first and second surfaces of the plunging assembly, wherein the seal includes a first portion coupled to the plunging assembly and disposed in an annular groove, the first portion having a width extending along the longitudinal axis between a first end at or near a first end of the groove and a second end at or near the second end of the groove, and a second portion coupled to the first portion at an interface, the interface spaced along the longitudinal axis from each of the first and second ends of the first portion, and wherein the plunging assembly is configured to filter a liquid as the liquid moves from the inner cavity of the outer container through the filtration assembly to the inner bore of the plunging assembly.
A filtration container assembly, comprising:
- an outer container having a first open end and a second closed end and defining an inner cavity;
- and
- a plunging assembly having a longitudinal axis and being 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, a filtration assembly in fluid communication with the inner bore, and a seal having a first portion coupled to the plunging assembly and disposed in an annular groove and a second portion coupled to the first portion such that the second portion is disposed between the outer container and the inner sleeve, wherein the plunging assembly is configured to filter a liquid as the liquid moves from the inner cavity of the outer container through the filtration assembly to the inner bore of the plunging assembly, wherein the seal is movable between first and second positions, wherein in the first position, the second portion of the seal forms a seal between the outer container and the inner sleeve, and wherein in the second position, the plunging assembly forms a pathway for a fluid to release pressure in the outer container.
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 defines a longitudinal axis and an inner bore, wherein the plunging assembly includes an inner sleeve having a first end and a second end and an outer wall, a filtration assembly in fluid communication with the inner bore, and a seal movable between first and second surfaces of the plunging assembly, wherein the seal includes a first portion coupled to the plunging assembly and disposed in an annular groove, the first portion having a width extending along the longitudinal axis between a first end at or near a first end of the groove and a second end at or near the second end of the groove, and a second portion coupled to the first portion at an interface, the interface spaced along the longitudinal axis from each of the first and second ends of the first portion;
- 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 to the inner bore of the plunging assembly.
