Abstract

A vacuum cleaner bag assembly is adapted to be removably disposed within a tank of a vacuum cleaner, and the bag assembly includes a panel assembly made from a first material and forming an enclosure having an interior volume, and an aperture extends through the panel assembly. A shield member may be disposed within the interior volume and secured to one or more portions of the panel assembly, and the shield member may comprise a second material that is different than the first material. The first material may have a wicking barrier that inhibits wicking when the bag assembly becomes wet. The shield member is adapted to protect a portion of the panel assembly when the vacuum cleaner bag assembly is disposed within the tank and, together with the wicking barrier and a properly chosen first material, enhances performance of the vacuum bag assembly when wet.

First claim

What is claimed is:

1. A vacuum cleaner bag assembly adapted to be removably disposed within a tank of a vacuum cleaner, the vacuum cleaner bag assembly comprising:
a first outer sheet comprising a first material, wherein the first material is a non-woven material that is a wood pulp and polyester blend;
a second outer sheet comprising the first material; and
a wicking barrier disposed along or impregnated into a portion of at least one of the first sheet or the second sheet, the wicking barrier constructed from a non-wicking material, wherein when the vacuum cleaner bag assembly is disposed within the tank;
wherein an aperture is disposed through the first outer sheet and the wicking barrier comprises one or more segments that divide the portion of the at least one of the first sheet or the second sheet into a first area and a second area.

2. The vacuum cleaner bag assembly of claim 1 , wherein the wood pulp and polyester blend is between about 55% wood pulp and about 45% wood pulp.

3. The vacuum cleaner bag assembly of claim 1 , wherein the wood pulp and polyester blend is between about 55% polyester and about 45% polyester.

4. The vacuum cleaner bag assembly of claim 1 , wherein the wood pulp and polyester blend is about 55% wood pulp and about 45% polyester.

5. The vacuum cleaner bag assembly of claim 1 , wherein the one or more segments of the wicking barrier have at least one of a linear shape, a U-shape, a V-shape, a trapezoidal shape, partial rectangular shape, or a semi-circular shape.

6. The vacuum cleaner bag assembly of claim 1 , wherein the wicking barrier comprises an adhesive material.

7. The vacuum cleaner bag assembly of claim 6 , wherein the wicking barrier comprises a hot-melt adhesive material.

8. The vacuum cleaner bag assembly of claim 1 , wherein a grain of the first material is vertically aligned.

9. The vacuum cleaner bag assembly of claim 8 , wherein a wet strength of the first material is between about 25.1 lbs. and about 42.7 lbs.

10. The vacuum cleaner bag assembly of claim 1 , further comprising a shield member disposed between the first outer sheet and the second outer sheet, the shield member comprising a second material that is different than the first material, the second material comprising a non-porous and non-absorbent flexible material.

11. A vacuum cleaner bag assembly adapted to be removably disposed within a tank of a vacuum cleaner, the vacuum cleaner bag assembly comprising:
a panel assembly forming an enclosure having an interior volume, wherein an aperture extends through the panel assembly, the aperture adapted to receive debris exiting an outlet end of a hose assembly such that the debris is retained within the interior volume, wherein the panel assembly comprises a nonwoven material; and
a wicking barrier disposed on or impregnated into a portion of the panel assembly, the wicking barrier constructed from a non-wicking material and comprising one or more segments that divide the portion of the panel assembly into a first area and a second area.

12. The vacuum cleaner bag assembly of claim 11 , wherein the one or more segments of the wicking barrier have at least one of a linear shape, a U-shape, a V-shape, a trapezoidal shape, partial rectangular shape, or a semi-circular shape.

13. A vacuum cleaner bag assembly of claim 11 , wherein the first area is adapted to be adjacent to a portion of a filter assembly of the vacuum cleaner when the vacuum cleaner bag assembly is disposed within the tank of the vacuum cleaner.

14. The vacuum cleaner bag assembly of claim 11 , wherein the wicking barrier comprises an adhesive material.

15. The vacuum cleaner bag assembly of claim 11 , wherein the nonwoven material is a wood pulp and polyester blend.

16. The vacuum cleaner bag assembly of claim 15 , wherein the wood pulp and polyester blend is between about 55% wood pulp and about 45% wood pulp.

17. The vacuum cleaner bag assembly of claim 16 , wherein a wet strength of the first material is one of about 28.7 lbs., about 32.46 lbs., about 27.3 lbs., about 34.0 lbs., about 30.6 lbs., about 37.7 lbs., about 25.1 lbs., about 42.7 lbs., about 28.34 lbs., or about 37.8 lbs.

18. The vacuum cleaner bag assembly of claim 15 , wherein the wood pulp and polyester blend is between about 55% polyester and about 45% polyester.

19. The vacuum cleaner bag assembly of claim 15 , wherein the wood pulp and polyester blend is about 55% wood pulp and about 45% polyester.

20. The vacuum cleaner bag assembly of claim 11 , further comprising a shield member disposed within the interior volume and secured to one or more portions of the panel assembly, wherein the shield member comprises a second material that is different than the first material.
