ABSTRACT:
A temperature indicating container apparatus includes an inner container portion made from substantially heat insulative material. A thermochromic-substance-containing portion is juxtaposed against an outside surface of the inner container portion, such that color changes of the thermochromic-substance-containing portion can be seen from outside the inner container portion. The thermochromic-substance-containing portion may be in a form of a jacket around the outside surface of the inner container portion. The jacket may include a plurality of windows. An outermost container portion may be located outside both the thermochromic-substance-containing jacket and the inner container portion. The outermost container portion is light transmissive such that color changes of the thermochromic-substance-containing jacket can be seen from outside the outermost container portion. A bridge element bridges top portions of the inner container portion and the outermost container portion. The bridge element, a top portion of the inner container portion, and a top portion of the outermost container portion form a unified, liquid-tight seal. A lid assembly includes a lid portion for covering the inner container portion and the thermochromic-substance-containing portion. The lid portion may include thermochromic substances. The lid assembly may also include an orientation-changeable signal assembly that is connected to a top surface of the lid portion.
