Abstract
A construct for heating a food item in a microwave oven includes a thermochromic ink. The thermochromic ink may be used alone or with other inks to create an impression of active heating, provide status information or instructions to the user, provide instructions about the use of the construct, provide information about a theme presented with the construct provide educational information, provide entertainment to a user, or any combination thereof.
Claims36
A construct for heating a food item in a microwave oven, the construct comprising:
- a presentment formed at least partially from a thermochromic ink that undergoes a change in color as a function of temperature, wherein the presentment creates an impression of an active heating process.
A construct for heating a food item in a microwave oven, the construct comprising:
- an indicium formed at least partially from a thermochromic ink that undergoes a change in color at a transition temperature, wherein the change in color of the thermochromic ink indicates the status of the heating of the food item.
A construct for heating a food item in a microwave oven, comprising:
- a presentment formed from an ink applied to at least a portion of an outer surface of the construct;
- and
- a thermochromic ink overlying the presentment, wherein
- the thermochromic ink transitions from a colored state to a colorless state at a color transition temperature,
- the color transition temperature corresponds to the temperature of the food item at a particular point in the heating process,
- the transition from the colored state to the colorless state reveals the presentment, and
- the revealing of the presentment serves as an indicator that the food item has reached the particular point in the heating process.
A construct for heating a food item in a microwave oven, the construct comprising a thermochromic ink overlying at least a portion of an outer surface thereof, wherein:
- the thermochromic ink changes from a first color to a second color in response to thermal energy,
- the thermochromic ink is selected such that the change from the first color to the second color occurs at a predetermined point in the heating process of the food item, and
- the change in color of the thermochromic ink is used to create an impression of active heating, provide a status of the heating of the food item, provide instructions for processing or handling the food item, or any combination thereof.
A construct for heating a food item in a microwave oven, the construct comprising a thermochromic ink that undergoes a change in color as a function of temperature to reveal a presentment, wherein the presentment:
- provides instructions about the use of the construct;
- provides information about a theme presented with the construct;
- provides educational information;
- provides entertainment to a user;
- or
- any combination thereof.
