## Abstract

A combination of a container in which foodstuffs are to be prepared and stored, and an electrically powered food-processing appliance, wherein at least a portion of the container includes material responsive to electrical energy applied thereto to vary the transmission of light therethrough. The appliance is configured for selectively applying electrical energy to the material, whereby at least said portion of said container is selectively rendered more transmissive to light.

## Claims

### Claim 1

The combination comprising:
a container in which foodstuffs are to be prepared and stored, and an electrically powered food-processing appliance,
at least a portion of the container includes material responsive to electrical energy applied thereto to vary the transmission of light therethrough; the appliance
is configured for selectively applying electrical energy to said material of the container, whereby at least said portion of said container is selectively rendered more transmissive to light so that a user can view preparation of the foodstuffs, with the material of the container returning to an opaque state after use of the food-processing appliance so that the foodstuffs can be stored in the while resisting spoilage; wherein the container is configured to dock with the food-processing appliance; and wherein the container incorporates a switch for selectively applying said electrical energy to said material, and the food-processing appliance is configured to actuate the switch.

### Claim 2 (depends on 1)

The combination of claim 1, wherein said food-processing appliance is configured for automatically actuating said switch in response to a docking of said container with said food-processing appliance.

### Claim 3 (depends on 1)

The combination of claim 1, wherein actuation of said switch is manually controllable by a user of the food-processing appliance.

### Claim 4 (depends on 1)

The combination of claim 1, wherein the container accommodates a food processing tool that is configured to be driven in rotation from a drive on said food-processing appliance.

### Claim 5 (depends on 1)

The combination of claim 1, wherein said material is a liquid crystalline material that is configured to display information on the container.

### Claim 6

Apparatus comprising:
a container in which foodstuffs are to be prepared and stored;
an electrically powered food-processing appliance, the container being removably dockable in the appliance;
at least a portion of the container including material responsive to electrical energy applied thereto to vary the transmission of light therethrough, the material being substantially opaque without energy being applied thereto and being transmissive of light when energy is applied thereto;
a switch;
the appliance being configured for applying the energy to said material of the container through the switch when the container is docked with the food-processing appliance, whereby at least said portion of said container is selectively rendered more transmissive to light so that a user can view preparation of the foodstuffs, with the material of the container returning to an substantially opaque state when said container is un-docked from said food-processing appliance so that the foodstuffs can be stored in the container while resisting spoilage.
