Adjustable beverage container holder

A beverage container carrier comprising a resilient, insulating concave, cylindrical casing for snugly surrounding a beverage container, said casing having parallel columns of at least two vertically aligned apertures located diametrically opposite each other on each side of said casing, and a flexible line is formed in a loop with trailing extremities, each of said trailing extremities being laced through the apertures in opposite ones of said vertical columns, and the resilient structure of said casing squeezes said line against said container to exert friction thereon, thereby preventing the weight of said container from causing relative movement between said casing, said container and said line, and said resilient casing elastically yields to accomodate longitudinal adjustment of said line relative to said casing when longitudinal tension on said line is exerted which exceeds the weight of a container to lengthen and shorten said loop as desired, and enlargements are located in said trailing extremities of said line below the lowermost of each of said apertures in each of said columns of apertures to limit downward movement of said casing and said container relative to said line.
