Abstract
The portable insulating receptacle has a receptacle main body containing an inner shell, an outer shell and a heat-insulating section defined between the inner shell and the outer shell, and a cover removably applied to an opening of the receptacle main body. The insulating receptacle has on the outer shell non-slip means over a zone covering both a center of gravity when the receptacle is full and a center of gravity when the receptacle is empty. The portable insulating receptacle has a cylindrical shape which reduces toward the top or bottom. The non-slip means is a recess, ridge or corrugated portion which is formed integrally with the outer shell or a synthetic resin non-slip member attached to the outer shell.
