Processing tool attachments for a food mixing device

A processing tool for a blender comprising:

• a shaft configured to couple to a blender at a first end;
• a body connected to the shaft at a second end;
• the body having a working portion;
• the working portion having a top surface and a bottom surface interconnected by a sidewall;
• the working portion includes at least a first opening extending between the top surface and the bottom surface;
• the first opening includes a leading end interconnected to a trailing end;
• wherein at least a portion of the trailing end forms an angle with the bottom surface that is less than 90 degrees.

A processing tool for a blender comprising:

• a shaft configured to couple to a blender at a first end;
• a body connected to the shaft at a second end;
• the body having a working portion;
• the working portion including a wire frame having an first portion interconnected to a second portion;
• the first portion being closer to the first end than the second portion;
• the first portion being connected to the body;
• wherein as the wire frame rotates, the wire frame defines a cross-sectional area at the first portion that is smaller than the cross-sectional area defined by the wire frame at the second portion;
• wherein the cross-sectional area defined by the wire frame at the first portion is substantially constant throughout the upper portion;
• and wherein the cross-sectional area defined by the wire frame at the second portion increases with distance towards the second end.

A container for use with a hand-held blender having a processing tool attached thereto comprising:

• a sidewall interconnected to a base;
• the sidewall and base defining an interior and an opening;
• and
• a lid adapted to be received in the opening;
• the lid includes a blender opening configured to insert the hand-held blender therethrough and into the container interior;
• wherein the container is adapted to rest the blender against the lid at the blender opening such that the processing tool of the blender is spaced from the base.

A blender comprising:

• a processing tool;
• a housing;
• a motor located within the housing;
• the processing tool being coupled to the motor to be rotalably driven by the motor;
• the motor includes a first motor terminal and a second motor terminal;
• a battery cartridge located within the housing;
• the battery cartridge adapted to receive at least one battery;
• the battery cartridge having a first end and a second end;
• the battery cartridge including a first cartridge terminal and a second cartridge terminal at the second end;
• a actuator coupled to the first end of the battery cartridge;
• a circuit board located between the motor and the battery cartridge;
• the circuit board being adapted to electrically connect to the at least one battery to power the motor;
• the circuit board including a resilient first contact, a resilient second contact;
• a third contact, and at least one resistor;
• wherein the resilient first contact is electrically connected to the first motor terminal through the resistor;
• the resilient second contact is electrically connected to the second motor terminal;
• the third contact is electrically connected to the first motor terminal;
• the resilient first contact being located above the third contact;
• a first spring attached to the battery cartridge;
• the first spring extending from the second end of the battery cartridge;
• wherein the battery cartridge is spaced from the circuit board by the first spring such that the blender is not activated;
• wherein depressing the actuator compresses the first spring to a first position in which the first cartridge terminal and the second cartridge terminal are in contact with the resilient first contact and the resilient second contact, respectively, to activate the motor to rotate the processing tool at a first speed;
• wherein depressing the actuator further compresses the first spring further to a second position in which the resilient first contact is flexed to contact the third contact to activate the motor to rotate the processing tool at a second speed;
• the second speed being greater than the first speed due to the resistor being shunted out of the circuit when the resilient first contact contacts the third contact.
