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 shield member is adapted to protect a portion of the panel assembly when the vacuum cleaner bag assembly is disposed within the tank.

First claim

What is claimed is:

1. A vacuum cleaner bag assembly adapted to be removably disposed within a vacuum cleaner, the vacuum cleaner bag assembly comprising:
a panel assembly comprising a first panel and a second panel forming an enclosure having an interior volume, wherein an aperture extends through the first panel, the aperture adapted to receive debris exiting an outlet end of a hose assembly such that the debris is retained within the interior volume, each of the first panel and the second panel including an outer sheet and a liner sheet, wherein each of the outer sheets comprises a first outer material and each of the liner sheets comprises a first liner material; and
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 each of the first outer material and the first liner material, the shield member extends vertically from a first point at or adjacent to a top portion of the panel assembly to a second point vertically disposed between a bottom portion of the aperture and a bottom portion of the panel assembly, the shield member is disposed opposite the aperture on the second panel and directly exposed to the aperture when the vacuum cleaner bag assembly is disposed within a tank such that the shield member protects a corresponding portion of the panel assembly from being impacted by debris passing through the aperture and into the interior volume;
wherein the first outer material is a wood pulp and polyester blend material and the first liner material is a non-woven, high efficiency filtration material, wherein the shield member includes a first portion and a second portion, the shield member being folded about a transverse axis that is disposed at or adjacent to the first point such that during normal operation, the first portion of the shield member abuts and applies a biasing force to the first panel of the panel assembly.

2. The vacuum cleaner bag assembly of claim 1 , wherein each of the first outer material and the first liner material is a non-woven material.

3. The vacuum cleaner bag assembly of claim 1 , wherein the first liner material is a polypropylene material.

4. The vacuum cleaner bag assembly of claim 3 , wherein the first liner material is a polypropylene melt blown material.

5. The vacuum cleaner bag assembly of claim 1 , wherein the second material is a flexible plastic.

6. The vacuum cleaner bag assembly of claim 1 , wherein the second material does not include wood pulp.

7. The vacuum cleaner bag assembly of claim 1 , wherein the shield member vertically extends from a point adjacent to a top portion of a filter assembly at least partially disposed within the tank to a point adjacent to a bottom portion of the filter assembly when the vacuum cleaner bag assembly is disposed within the tank.

8. The vacuum cleaner bag assembly of claim 1 , wherein the shield member vertically extends from a point adjacent to a top portion of a filter assembly at least partially disposed within the tank to a point between the top portion of the filter assembly and a bottom portion of the filter assembly when the vacuum cleaner bag assembly is disposed within the tank.

9. The vacuum cleaner bag assembly of claim 1 , wherein the shield member includes a first portion extending from the transverse axis to a first transverse edge and a second portion extending from the transverse axis to a second transverse edge.

10. The vacuum cleaner bag assembly of claim 9 , wherein a vertical distance between the transverse axis and the first transverse edge is equal to a vertical distance between the transverse axis and the second transverse edge.

11. The vacuum cleaner bag assembly of claim 9 , wherein a first securement feature is formed along or adjacent to a first lateral edge of the shield member from the transverse axis to the second transverse edge of the first portion, and wherein a second securement feature is formed along or adjacent to a second lateral edge of the shield member from the transverse axis to the second transverse edge of the first portion.

12. The vacuum cleaner bag assembly of claim 11 , wherein each of the first securement feature and the second securement feature is a heat seal.

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

14. The vacuum cleaner bag assembly of claim 13 , wherein a dry strength of the first material is between about 11.6 lbs. and about 20.0 lbs.

15. The vacuum cleaner bag assembly of claim 14 , wherein the dry strength of the first material is one of about 16.0 lbs., about 13.2 lbs., about 11.6 lbs., about 18 lbs., about 14.0 lbs., about 15.5 lbs., about 12.5 lbs., about 20.0 lbs., or about 16.4 lbs.

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

17. The vacuum cleaner bag assembly of claim 1 , wherein the aperture is adjacent a top of the panel assembly and a grain of the first material is generally vertically aligned.

18. The vacuum cleaner bag assembly of claim 1 , wherein the first liner material is different than the first outer material.

19. A vacuum cleaner assembly comprising:
a tank having an interior volume;
a suction assembly coupled to a top portion of the tank;
a filter assembly coupled to the suction assembly and extending into the interior volume of the tank;
a hose assembly coupled to the tank;
a vacuum cleaner bag assembly removably disposed within the interior volume of the tank, 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 the hose assembly such that the debris is retained within the interior volume, the panel assembly comprising a first panel and a second panel, with each of the first panel and the second panel including an outer sheet and a liner sheet, wherein each of the outer sheets comprises a first outer material and each of the liner sheets comprises a first liner material; and
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 each of the first outer material and the first liner material, the shield member extending vertically from a first point at or adjacent to a top portion of the panel assembly to a second point vertically disposed between a bottom portion of the aperture and a bottom portion of the panel assembly, the shield member is disposed opposite the aperture in the panel assembly such that the shield member protects a corresponding portion of the panel assembly from being impacted by debris passing through the aperture and into the interior volume, wherein the first outer material is a non-woven wood pulp material and the first liner material is a non-woven polyester material, wherein the shield member includes a first portion and a second portion, the shield member being folded about a transverse axis that is disposed at or adjacent to the first point such that during normal operation, the first portion of the shield member abuts and applies a biasing force to the first panel of the panel assembly.
