Core pin bag dispenser

Abstract

A core pin bag dispenser includes a planar base sized and shaped to fit beneath a roll of film bags. First and second upwardly extending rods are mounted to the base. A retaining pin is sized and shaped to fit slidably within a hollow core of the bag roll. The pin has first and second orthogonal apertures located adjacent the first and second ends that are spaced apart by at least a width of the roll of film bags and are sized and shaped to fit slidably over the first and second upwardly extending rods. An upward pointing snagging hook is mounted adjacent a front edge of the base and is sized and shaped to engage either a chisel cut or a perforation in the bags. Two of the dispensers are mounted to an adapter designed to fit into the side channels of a bin mounted to a vertical surface.
