Abstract:
1. A food or beverage container, comprising: an upper wall; a lower wall; and a side wall extending between the upper wall and the lower wall, at least one of the upper wall and the lower wall including a phase change material distributed with a first concentration on the at least one of the upper wall and the lower wall, the side wall including a phase change material distributed with a second concentration on a portion of the side wall, the phase change material on the side wall having a latent heat of at least 40 J/g and a transition temperature in the range of 0° C. to 100° C., the phase change material on the side wall having a higher latent heat than the phase change material on the at least one of the upper wall or the lower wall, the phase change materials on both the side wall and the at least one of the upper or lower walls providing thermal regulation based on at least one of absorption and release of the latent heat at the transition temperature, wherein a portion of the side wall that includes phase change material corresponds to the portion of the food or beverage container that is typically in contact with a user during use of the container.
