Abstract: A container lid includes a conventional main or pour opening and a vent opening spaced from the main opening. A vent score defines the shape of the vent opening, and a vent panel covers the vent opening. The vent panel has a raised convex shape. The lower surface of the tab handle includes a protruding portion, seen as a concave shaped element when viewed from above the container lid. The protruding portion of the tab handle can be aligned with the vent panel so application of a downward force on the tab handle transfers force to the vent panel and breaks the vent score. The shapes of the vent panel and concave element of the tab handle can be adjusted for selective and controlled force transfer to create the vent opening.

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 preferably sprayed coated onto 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.
