Abstract
Abstract An inner auxiliary mixing bowl having an upwardly extending tubular post is removably nested within the outer mixing bowl of a food processor. The tubular post of the inner bowl is tapered with the upper, smaller end thereof being positioned closely about the uppermost end of the shaft and adjacent to the underside of the cutting tool that is driven by the motor of the food processor. Thus, the likelihood of the processed food passing between the inner surface of the tubular post and the outer surface of the driven shaft is minimized. This thereby reduces the likelihood of contamination of the interior of the motor by the processed food. The inner mixing bowl is made of a plastic material that permits it to be heated and frozen thereby vastly increasing its utility. In addition, a removable cover is provided for the inner mixing bowl so that the content thereof may be readily transported. The inner mixing bowl is preferably translucent and indicia are provided on the outside surface thereof for indicating the quantity of food within the bowl.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
167 words
A food processor comprising, in combination: an electric motor having a drive shaft, cutting tool means including a food processing blade portion having an integrally formed driven shaft, said driven shaft being coupled to said drive shaft for rotation therewith, an outer bowl having a basewall including an opening through which said drive shaft extends and a side wall extending upwardly from said basewall, an inner bowl removably nested within said outer bowl for receiving therein the food to be processed by said blade portion, said inner bowl including a sidewall and a basewall having a tubular post, at least a portion of said tubular post being positioned in close proximity about said driven shaft of said cutting tool means and terminating adjacent the underside of said cutting tool means to thereby minimize the passage of processed food through said opening in said basewall of said outer bowl, whereby said motor is not contaminated by said processed food, and cover means removably coupled to said outer bowl.
Claim 2
Dependent Claim
167 words
A food processor comprising, in combination: an electric motor having a drive shaft, cutting tool means including a food processing blade portion having an integrally formed driven shaft, said driven shaft being coupled to said drive shaft for rotation therewith, an outer bowl having a basewall including an opening through which said drive shaft extends and a side wall extending upwardly from said basewall, an inner bowl removably nested within said outer bowl for receiving therein the food to be processed by said blade portion, said inner bowl including a sidewall and a basewall having a tubular post, at least a portion of said tubular post being positioned in close proximity about said driven shaft of said cutting tool means and terminating adjacent the underside of said cutting tool means to thereby minimize the passage of processed food through said opening in said basewall of said outer bowl, whereby said motor is not contaminated by said processed food, and cover means removably coupled to said outer bowl.
