Abstract: An inexpensive reusable insulated jacket for removably receiving an open beverage can therewith, and to maintain its contents in refrigerated condition, having a cover for preventing windblown sand and other foreign materials from entering the can and thereby contaminating its contents. The jacket is designed so that it is comprised of only two separate molded pieces of insulating material, a cylindrical cup-like member and a cover, the cover being secured to the cup-like member solely by a small elastic band anchored upon the cup-like member and extending over the cover while urging same toward closed protecting position.A bearing surface is molded into the cover and cooperates with a bearing surface molded into the cup-like member, so as to obviate the need for a fixed hinge member, the latter being difficult to secure and maintain in molded insulating material and relatively expensive to manufacture.
