    摘要: An insulating paperboard container is disclosed including a container body having a side wall and a bottom wall with the one side wall including a base layer and an insulating layer on at least a portion of the base layer, preferably on an inside surface of the side wall. The insulating layer being selectively adhered to at least a portion of the base layer such that the selective adhering of the insulating layer to the base layer creates air pockets between the insulating layer and the base layer with the air pockets being expandable in response to contact with a heated liquid. Such a container is formed from an insulating stock material comprising a paperboard base layer and an insulating layer overlying at least a portion of at least of one surface of the base layer with the insulating layer being selectively adhered to the surface of the base layer forming enclosed regions between the base layer and the insulating layer. In order to ensure the formation of pronounced air pockets between the insulating layer and the base layer, the paperboard base layer may be debossed, creating debossed regions with the insulating layer being adhered over the openings of the debossed regions.
