Abstract

An infant drinking cup is described. The infant drinking cup is a first color when at room temperature. When the cup is filled with a cold beverage, the portion of the cup below the fill line changes to a second color. When handled by an infant, those areas below the fill line in contact with the infant's warm hands change color back to the first color. The process is fully reversible, such that the infant drinking cup can change from the cold color to the warm color, and vice versa, repeatedly.

Claims (10)

1. An infant drinking cup comprising:
a fluid receiving vessel which is a first color when at a temperature greater than a critical hot temperature, the infant drinking cup being a second color when below a critical cold temperature, the second color being different than the first color, and the critical hot temperature being higher than the critical cold temperature.
2. The infant drinking cup of claim 1 wherein the cup expresses hybrid shades of color when at temperatures between the critical hot and critical cold temperatures.
3. The infant drinking cup of claim 1, wherein the second color is dominant to or darker than the first color, such that the second color masks the first color when the second color is expressed.
4. The infant drinking cup of claim 1 wherein the fluid receiving vessel is formed from a blend of a polymer and a temperature responsive coloring composition.
5. An infant drinking cup comprising:
a polymer and a temperature responsive coloring composition, the temperature responsive coloring composition expressing a cold color below a critical cold temperature, and the temperature responsive coloring composition not expressing the cold color above a critical hot temperature.
6. The infant drinking cup of claim 4 or claim 5 wherein the polymer is polypropylene.
7. The infant drinking cup of claim 4 or claim 5 wherein the temperature responsive coloring composition comprises an olefin polymer and a thermochromic material, the thermochromic material having an acid-responsive chromogenic compound, and an acidic substance.
8. The infant drinking cup of claim 4 or claim 5 wherein the temperature responsive coloring composition is blended with the polymer at a concentration of between 6 and 10 percent by weight of the blend.
9. The infant drinking cup of claim 1 or claim 5 wherein the critical hot temperature is between 19 and 27 degrees centigrade.
10. The infant drinking cup of claim 1 or claim 5 wherein the critical cold temperature is between 10 and 18 degrees centigrade.
