Abstract

Cups that color liquid contents and methods of manufacturing the same are disclosed herein. The cups include an inner wall with a colorant disposed and affixed therein. The colorant is predisposed (i.e., affixed) before the introduction of a liquid, and remains affixed until a liquid is introduced into the cup. The colorant can be disposed within a recess. The colorant can also be affixed to a first cup such that stacking an identical cup within the first cup does not result in the colorant touching the identical cup.
