Abstract

A filtration container assembly generally includes an outer container having a first end and a second end and defining an inner cavity, and a plunging assembly configured to be received within the outer container inner cavity, wherein the plunging assembly includes an inner sleeve having a first end and a second end and an outer wall defining an inner bore, wherein the outer wall is continuous from the first end to the second end, and a filtration assembly coupled to the inner sleeve at the second end.

Claims (32)

1 . A filtration container assembly, the assembly comprising:

(a) an outer container having a first end and a second end and defining an inner cavity; and

(b) a plunging assembly configured to be received within the outer container inner cavity, wherein the plunging assembly includes an inner sleeve having a first end and a second end and an outer wall defining an inner bore, wherein the outer wall is continuous from the first end to the second end, and a filtration assembly coupled to the inner sleeve at the second end.

2 . The assembly of claim 1 , wherein the outer container has a first open end and a second closed end.

3 . The assembly of claim 1 , wherein the outer container has a substantially cylindrical outer wall defining the inner cavity.

4 . The assembly of claim 3 , wherein the inner sleeve has a substantially cylindrical outer wall.

5 . The assembly of claim 4 , wherein the inner cavity of the outer container and the inner sleeve of the plunging assembly are concentric with one another.

6 . The assembly of claim 1 , wherein the plunging assembly is configured to nest in the inner cavity of the outer container.

7 . (canceled)

8 . The assembly of claim 1 , wherein the filtration assembly includes a device for pressure release.

9 . The assembly of claim 8 , wherein the device for pressure release includes a floating seal.

10 . The assembly of claim 9 , wherein the floating seal is received within an annular space along the outer perimeter of the filtration assembly.

11 . The assembly of claim 8 , wherein the device for pressure release includes a pressure release valve.

12 . The assembly of claim 8 , wherein the device for pressure release is configured to maintain a seal when the plunging assembly is being inserted into the outer container.

13 . The assembly of claim 12 , wherein the device for pressure release is configured to release the seal when the plunging assembly is being removed from the outer container.

14 . The assembly of claim 1 , wherein the plunging assembly includes a collar assembly for interfacing with the outer container.

15 . The assembly of claim 14 , wherein the collar assembly is configured to create an interference fit between the plunging assembly and the outer container.

16 . The assembly of claim 14 , wherein the collar assembly includes a seal and a collar.

17 . The assembly of claim 14 , wherein the collar assembly is configured to engage with a plurality of depressions in the outer wall of the inner sleeve.

18 . The assembly of claim 1 , wherein the filtration assembly is releasably coupled to the inner sleeve at the second end.

19 . The assembly of claim 18 , wherein the filtration assembly and the inner sleeve are releasably coupled by a threaded connection.

20 . The assembly of claim 19 , wherein the inner sleeve includes threads at the second end.

21 . The assembly of claim 19 , wherein the filtration assembly includes a housing having threads extending from the filtration assembly.

22 - 26 . (canceled)

27 . A filtration container assembly, the assembly comprising:

(a) an outer container having a first end and a second end and defining an inner cavity; and

(b) a plunging assembly configured to be received within the outer container inner cavity, wherein the plunging assembly includes an inner sleeve having a first end and a second end and defining an inner bore, wherein the cross-sectional area of the inner sleeve is substantially the same at the first end and the second end, and a filtration assembly coupled to the inner sleeve at the second end.

28 . A method of filtering liquids, the method comprising:

(a) obtaining an outer container having an inner cavity and filling at least a portion of the outer container with a liquid;

(b) obtaining a plunging assembly having an inner sleeve having a first end and a second end and defining an inner bore, wherein the plunging assembly is configured to be received within the inner cavity of the outer container, wherein the inner sleeve has a continuous outer wall extending from the first end to the second end, and wherein the plunging assembly includes a filter coupled to the plunging assembly at the second end; and

(c) pressing the plunging assembly into the inner cavity of the outer container, such that the liquid flow from the inner cavity of the outer container through the filter and into the inner sleeve of the plunging assembly.

29 - 30 . (canceled)
