Abstract

A filtration device ( 10 A, 10 B, 10 C) comprising one or more filtration media ( 20 ) secured by one or more activatable adhesive layers ( 22 ). A method of forming a filtration device, including: (a) forming the one or more adhesive layers into a desired shape; (b) activating the one or more adhesive layers; (c) securing the one or more filtration media to the one or more adhesive layers; and (d) curing the one or more adhesive layers.

Claims (22)

1 . A filtration device comprising:

one or more filtration media secured by one or more activatable adhesive layers;

wherein the one or more activatable adhesive layers are heat activated to adhere, cure, and foam, so that the one or more filtration media bonds to the one or more activatable adhesive layers;

wherein the one or more activatable adhesive layers are die-cut into a desired shape;

wherein the one or more activatable adhesive layers form an adhesive housing;

wherein the adhesive housing encompasses one or more sides of the one or more filtration media; and

wherein the one or more activatable adhesive layers are a thermosetting material, and wherein the thermosetting material is an epoxy.

2 . The filtration device according to claim 1 , wherein the one or more activatable adhesive layers are dry to the touch and free of flow prior to activation of the one or more activatable adhesive layers.

3 . The filtration device according to claim 1 , wherein the one or more activatable adhesive layers maintain a sufficiently high viscosity during and prior to activation to substantially prevent flow independent of temperature or environmental conditions.

4 . The filtration device according to claim 3 , wherein the one or more filtration media are adhered to the one or more activatable adhesive layers within a mold.

5 . The filtration device according to claim 1 , wherein the one or more activatable adhesive layers form one or more end caps for the one or more filtration media.

6 . The filtration device according to claim 1 , wherein the one or more filtration media are bonded to a second filtration medium via the one or more activatable adhesive layers.

7 . The filtration device according to claim 1 , wherein prior to activation, the one or more activatable adhesive layers are a solid.

8 . The filtration device according to claim 1 , wherein the one or more activatable adhesive layers are one or more of moisture-resistant, non-toxic, antimicrobial, and antifungal.

9 . The filtration device according to claim 4 , wherein the one or more filtration media are located into the mold where one or more activatable adhesive layers are injected into the mold and activated so that the one or more activatable adhesive layers expand and cure to form the one or more activatable adhesive layers around the one or more filtration media.

10 . The filtration device according to claim 1 , wherein the filtration device is flexible.

11 . The filtration device according to claim 1 , wherein the filtration device is formed in a continuous manner.

12 . The filtration device according to claim 1 , wherein the one or more activatable adhesive layers are free of any liquid adhesive.

13 . The filtration device according to claim 1 , wherein one or more liners are secured to the one or more activatable adhesive layers.

14 . The filtration device according to claim 12 , wherein the one or more activatable adhesive layers maintain a sufficiently high viscosity before and during activation such that the one or more filtration media and the one or more activatable adhesive layers can be applied to a contoured and/or skew surface without significant flow of the one or more activatable adhesive layers.

15 . The filtration device according to claim 1 , wherein the one or more activatable adhesive layers are extruded.

16 . The filtration device according to claim 1 , wherein the one or more activatable adhesive layers form one or more gaskets that form a connection surface between the filtration device and one or more additional components.
