Abstract: A thermal barrier liner is preferably spray coated onto the internal surface of a container. The liner is provided in embodiments including a closed cell substrate, a base layer having gas or liquid filled microcapsules, a base layer having microencapsulated solid-liquid phase change material, or combinations thereof. For the closed cell substrate embodiment, when the liner is under pressure within the container prior to the container being opened, the liner maintains a minimum thickness. When the container is opened and as pressure is released within the container, the liner expands to achieve equilibrium. The liner can be supplemented with a foaming agent to create cellular structures. Voids created by the microcapsules enhance the thermal barrier characteristics of the liner. The phase change material changes phase from a solid to a liquid state upon absorbing heat.

Abstract: A thermal barrier liner is provided to maintain a beverage within a container at a desired temperature. The thermal barrier liner is installed so as to make intimate contact with the internal surface of the container. According to a method of the invention, the liner is pre-made and mechanically inserted in the container prior to securing the top of the container to the sidewall. A closed cell structure is incorporated in the thermal barrier material. The closed cell structure causes the thermal barrier material to be gas permeable such that voids in the closed cell structure equilibrate with ambient pressure conditions. The voids change size based on changes in ambient pressure conditions as compared to pressure conditions in the thermal barrier material.

Abstract: A thermal barrier liner is provided to maintain a beverage within a container at a desired temperature. The thermal barrier liner is installed so to make intimate contact with the internal surface of the container. The thermal barrier liner may be provided in various embodiments including a closed cell substrate, a base layer having gas or liquid filled microcapsules, a base layer having microencapsulated solid-liquid phase change material, or combinations thereof. In the closed cell substrate embodiments, when the thermal barrier liner is under pressure within the container such as prior to the container being opened, the thermal barrier liner maintains a minimum profile or thickness. However, when the container is opened and as pressure is released within the container, the barrier liner expands to achieve equilibrium. The expanded or thickened barrier liner provides an effective thermal barrier thereby maintaining the beverage at a desired temperature for a longer period of time.
