Abstract
A container for maintaining human edible contents carried therein at a reduced temperature for an extended period of time is disclosed. The container is configured to have a first appearance and a second appearance and transitions between the first and second appearances at a predetermined temperature to provide a visual indication of the temperature of the container and the contents therein.
Claims15
A method comprising:
- providing, in a room temperature environment, a container having a second appearance configured to carry human edible contents therein, the container configured to provide a visual temperature indication thereon, the container configured to reversibly transition between a first appearance and the second appearance, wherein the container includes
- an inner shell configured to carry the human edible contents therein,
- an outer shell having a thermochromic resin additive surrounding said inner shell and integrally connected to the inner shell,
- a cavity defined between the inner shell and the outer shell, and
- a gelatinous material within the cavity positioned between the inner shell and the outer shell, wherein the gelatinous material is configured to maintain the container below a predetermined temperature for an extended period of time;
- visually inspecting the container for changes of the container from the second appearance to the first appearance;
- repeating the visually inspecting step one or more times;
- and
- removing the container when approximately eighty-five percent (85%) to about ninety-five percent (95%) of the visible outer shell is the first appearance.

A visual temperature-indicating container comprising:
- an inner shell configured to carry human edible contents therein;
- an outer shell surrounding said inner shell and integrally connected to the inner shell;
- a cavity defined between the inner shell and the outer shell;
- an insulation layer within the cavity and proximate to the outer shell;
- and
- a gelatinous material within the cavity positioned between the inner shell and the insulation layer, wherein the gelatinous material is configured to maintain the container below a predetermined temperature for an extended period of time;
- wherein the outer shell includes a thermochromic resin additive and the outer shell is configured to have a first appearance or a second appearance, wherein the outer shell is configured to change between the first and second appearances upon reaching and exceeding the predetermined temperature, and wherein the first and second appearances provide a visual temperature indication of the container, and wherein the first appearance and second appearance are different.
