Abstract

A blender assembly includes a blender jar having a bottom wall. The bottom wall includes first and second surfaces opposing one another and an interior edge defining an opening. A bearing housing is positioned at least partially within the opening and is spaced apart from the first surface of the bottom wall and the interior edge of the bottom wall. A nut is operably coupled with the bearing housing and is spaced apart from a second surface of the bottom wall. A gasket assembly is positioned to maintain a spacing of the bearing housing and the nut relative to the bottom wall. The gasket assembly is positioned over the interior edge of the bottom wall.

First claim

What is claimed is:

1. A blender assembly, comprising:
a blender jar having a bottom wall, wherein the bottom wall includes first and second surfaces opposing one another, and an interior edge defining an opening;
a bearing housing positioned at least partially within the opening and spaced apart from the first surface of the bottom wall and the interior edge of the bottom wall by a first spacing;
a nut operably coupled with the bearing housing and spaced apart from the second surface of the bottom wall by a second spacing; and
a gasket assembly positioned within the first spacing and the second spacing to maintain the first spacing between the bearing housing and the bottom wall and the second spacing between the nut and the bottom wall, wherein the gasket assembly is positioned over the interior edge of the bottom wall.

2. The blender assembly of claim 1 , wherein the gasket assembly includes a first gasket and a second gasket, and wherein the first gasket is positioned between the bearing housing and the first surface of the bottom wall and further positioned between the bearing housing and the interior edge of the bottom wall, and further wherein the second gasket is positioned between the nut and the second surface of the bottom wall.

3. The blender assembly of claim 2 , wherein the first gasket is integrally formed with the second gasket.

4. The blender assembly of claim 1 , wherein one of the bearing housing and the nut includes a shoulder configured to retain the gasket assembly.

5. The blender assembly of claim 1 , wherein one of the first and second surfaces of the bottom wall includes a retention rib configured to retain the gasket assembly.

6. A blender assembly, comprising:
a blender jar having a bottom wall, wherein the bottom wall includes an interior edge defining an opening;
a bearing housing positioned within the blender jar and extending at least partially through the opening, wherein the bearing housing is spaced apart from the bottom wall and the interior edge of the bottom wall by a first spacing;
a nut positioned exterior of the blender jar and operably coupled with the bearing housing, wherein the nut is spaced apart from the bottom wall by a second spacing;
a first gasket positioned to maintain the first spacing of the bearing housing relative to the bottom wall; and
a second gasket positioned to maintain the second spacing of the nut relative to the bottom wall.

7. The blender assembly of claim 6 , wherein the first and second gaskets are integrally formed as a single gasket positioned to surround the interior edge of the bottom wall.

8. The blender assembly of claim 6 , wherein the bearing housing includes a downwardly opening channel extending around a body portion of the bearing housing.

9. The blender assembly of claim 8 , wherein the first gasket is received within the downwardly opening channel of the bearing housing.

10. The blender assembly of claim 6 , wherein the nut includes an upwardly opening channel.

11. The blender assembly of claim 10 , wherein the second gasket is received in the upwardly opening channel of the nut.

12. The blender assembly of claim 6 , wherein the bottom wall includes opposed first and second surfaces, and further wherein one of the opposed first and second surfaces of the bottom wall includes a plurality of retention ribs configured to retain one of the first and second gaskets.

13. A blender assembly, comprising:
a blender jar having a bottom wall, wherein the bottom wall includes first and second surfaces and an interior edge defining an opening;
a bearing housing extending at least partially through the opening and spaced apart from the bottom wall and the interior edge of the bottom wall;
a nut operably coupled with the bearing housing and spaced apart from the bottom wall;
a first gasket positioned to maintain a first spacing between the bearing housing relative to the bottom wall;
a second gasket vertically spaced-apart from the first gasket and positioned to maintain a second spacing between the nut relative to the bottom wall; and
a retention feature configured to retain at least one of the first gasket and the second gasket.

14. The blender assembly of claim 13 , wherein the retention feature is a shoulder extending inwardly from one of the bearing housing and the nut toward the bottom wall.

15. The blender assembly of claim 13 , wherein the retention feature is a retention rib extending circumferentially about one of the first surface and the second surface.

16. The blender assembly of claim 15 , wherein the retention rib includes a toothed end configured to retain one of the first and second gaskets.

17. The blender assembly of claim 13 , further comprising:
a washer positioned between the bearing housing and the nut.

18. The blender assembly of claim 13 , wherein the nut is fixedly coupled with the bearing housing.

19. The blender assembly of claim 13 , wherein one of the first and second gaskets includes an L-shaped cross-section.
