Abstract

A chopping system generally includes a container having a bottom wall and a sidewall together defining a cavity. The sidewall has a rim, and the bottom wall has an upper surface with a central area having an entirely smooth contour. The system also includes a drive assembly configured for mounting on the rim to cover the cavity, and the system further includes a working assembly comprising at least one working member configured for operative attachment to the drive assembly such that, when the drive assembly is mounted on the rim, the working member is disposed within the cavity. The system further includes a base attached to the working assembly such that the working member is rotatable relative to the base. The base has a bottom surface that substantially mirrors the contour of the upper surface within the central area so as to be seated substantially flush thereagainst.

First claim

What is claimed is:

1. A chopping system comprising:
a container having a bottom wall and a sidewall together defining a cavity, wherein the sidewall has a rim and wherein the bottom wall has an upper surface with a central area having an entirely smooth contour;
a drive assembly configured for mounting on the rim of the container to cover the cavity;
a working assembly comprising at least one working member configured for operative attachment to the drive assembly such that, when the drive assembly is mounted on the rim of the container, the working member is disposed within the cavity of the container; and
a base attached to the working assembly such that the working member is rotatable relative to the base, wherein the base has a bottom surface that substantially mirrors the contour of the upper surface of the bottom wall of the container within the central area so as to be seated substantially flush against the bottom wall of the container without substantial open space or gaps between the base bottom surface and the upper surface the central area of the bottom wall of the container.

2. The chopping system of claim 1 , wherein the contour of the upper surface within the central area is flat without substantial contour.

3. The chopping system of claim 1 , wherein the base has a platform with a plurality of legs emanating outward away from one another, the legs extending to the sidewall at plural locations for centering the working assembly within the container.

4. The chopping system of claim 3 , wherein the platform has three legs.

5. The chopping system of claim 4 , wherein each adjacent pair of legs is joined together by an arcuate web such that the platform has a webbed, three-pointed star shape.

6. The chopping system of claim 1 , wherein the container is fabricated from oven-safe, tempered glass.

7. The chopping system of claim 1 , wherein the base has a platform fabricated from a hard plastic, and wherein the bottom surface of the base is defined by a soft silicone overmold of the hard plastic.

8. The chopping system of claim 1 , wherein the working assembly comprises a drive shaft configured to extend into the cavity substantially perpendicular to the bottom wall of the container, and wherein the working member extends outward from the drive shaft.

9. The chopping system of claim 8 , wherein the working member comprises a pair of blades extending outward from the drive shaft in different directions.

10. The chopping system of claim 8 , wherein the working member comprises a pair of blades extending outward from the drive shaft at different elevations.

11. The chopping system of claim 1 , further comprising a plurality of the containers that are interchangeable with one another for use with the drive assembly, the working assembly, and the base.

12. The chopping system of claim 1 , wherein the working assembly is attached to the base by a spring-loaded dampening system.

13. The chopping system of claim 1 , further comprising a cover that is coupleable to the rim of the container to at least partially seal the container when the drive assembly is not mounted on the rim.

14. A chopping system having a container with a sidewall and a bottom wall that together define a cavity, the chopping system comprising:
a working assembly comprising a drive shaft and a working member extending outward from the drive shaft; and
a base attached to the working assembly such that the working assembly is rotatable relative to the base, wherein the base comprises a platform having a bottom surface configured for seating on the bottom wall of the container and contoured such that at least substantially the whole bottom surface is flat so as to seat substantially flush against an upper surface of the bottom wall of the container without substantial open space or gaps between the base bottom surface and the upper surface the central area of the bottom wall of the container and wherein the bottom surface of the platform of the base is oriented substantially perpendicular to the drive shaft.

15. The chopping system of claim 14 , wherein the platform has a plurality of legs, the legs extending to the sidewall at plural locations for centering the working assembly within the container.

16. The chopping system of claim 15 , wherein the platform has three legs, and wherein each adjacent pair of legs is connected together by an arcuate web such that the platform is in the shape of a webbed, three-pointed star.

17. The chopping system of claim 14 , wherein the platform is fabricated from a hard plastic material.

18. The chopping system of claim 17 , wherein the bottom surface of the platform is defined by a soft silicone overmold of the hard plastic material.

19. The chopping system of claim 14 , wherein the working assembly is attached to the base by a spring-loaded dampening system.

20. A chopping system comprising:
a container fabricated from oven-safe, tempered glass and having a bottom wall and a sidewall together defining a cavity, wherein the sidewall has a rim and wherein the bottom wall has an upper surface with a central area having an entirely smooth contour, the sidewall tapering toward the bottom wall such that the cavity has a greater diameter at the rim than at the bottom wall;
a drive assembly configured for mounting on the rim of the container to cover the cavity, wherein the drive assembly comprises a motor;
a working assembly comprising a drive shaft configured for operative attachment to the motor so as to be rotatable by the motor, and a pair of blades attached to the drive shaft such that, when the drive assembly is mounted on the rim of the container with the drive shaft attached to the motor, the drive shaft extends into the cavity substantially perpendicular to the bottom wall of the container to dispose the blades within the cavity of the container, wherein the blades extend substantially radially outward from the drive shaft in different directions and at different elevations; and
a base attached to the working assembly such that the drive shaft and the blades are rotatable relative to the base, wherein the base has a platform with a plurality of legs emanating radially outward away from one another such that each pair of adjacent legs is connected by a web to form a webbed star shape, and wherein the platform has a bottom surface that substantially mirrors the contour of the upper surface of the bottom wall of the container within the central area so as to be seated substantially flush against the bottom wall of the container without substantial open space or gaps between the base bottom surface and the upper surface the central area of the bottom wall of the container.
