Combination insulated mug and beverage can holder

A combination of an insulated mug and a beverage container retainer ring comprising a generally cylindrical tubular mug body having a support base end and an opposite open top portion at respective ends of the mug body defined by outwardly flared rims at each end of the tubular body, an internally transversely extending wall adjacent one end of the tubular body that completely closes off the base end of the tubular body, the inside diameter of the body being sufficiently large to permit the insertion of a generally cylindrical beverage container therein, said mug body formed from a rigid insulated material, an annular beverage container retainer ring made of a flexible rubber-like material, said retainer ring having an inner tapered flexible generally radially inwardly extending circular lip, said ring also having an annular axially extending groove near its outer edge that defines an axially extending outer lip, said ring defining groove extends in a direction that is generally perpendicular to the radially inwardly extending lip, said annular ring groove further having a cross-sectional configuration that is generally similar in size and shape to the cross section of the flared rims of the mug at each end, said flared mug rims being angled outwardly from the axis of the tubular body so that the portion of the rim adjacent the tubular body is of a smaller diameter than the end portions of both mug rims, the largest diameter of the annular groove of the ring being slightly smaller than the large diameter of the mug rims that the retainer ring is fastened to, said outer lip of the ring having a rounded lower inside edge that functions to ease the assembly of the ring on the mug rims so that when the flexible ring is pressed on the mug rim at either end of the tubular body the outer lip of the ring is capable of being slipped over the flared rim adjacent thereto and resisting removal therefrom, the insulated mug being usable as a drinking vessel with the retainer ring being secured to the base rim for storing the retainer ring and for convenient access thereof, and said insulated mug being usable as a beverage container insulator and beverage container holder and retainer with the retainer ring being secured to the rim at the top portion of the mug and aiding in retaining a beverage container insertable into the mug by surrounding and engaging a wall portion of the beverage container.
