FOODSERVICE PRODUCT WITH A PCM

摘要

A single use multi-layered food service product such as paper cups, food containers, or sleeves constructed of materials including at least one phase changing material (PCM) with one or more additives to produce a thermal conductivity ratio of at least 2.0 W/mK and a melting point between 45 degrees C. and 80 degrees C. An inventive pattern for the placement and distribution of the PCM within its multilayered walls is described. The PCM is configured in order to minimize manufacturing cost and environmental impact while providing insulation and maximizing its ability to rapidly reduce and then maintain a safe and preferred temperature for served food or beverages.

主权项

1. A multilayer paper or plastic food service product sealed at its perimeter that actively and rapidly at first absorbs thermal energy which quickly cools thermally contacted food or liquid from a scalding to a more desirable temperature, stores that thermal energy and later releases and transfers it back to the thermally contacted food or liquid to maintain a desirable temperature for consumption.
