Hanging bag dispenser

Abstract

A hanging bag dispenser includes a bag support platform having a surface that contacts a last bag in a vertically supported bag pack. An angled mounting device is attached to the bag support platform to engage a mounting aperture that penetrates each bag in the bag pack. A positioning system is attached to the bag support platform and maintains the bag support platform at a sufficient height to allow the bag pack to extend downwardly from the mounting device. A pivotally mounted bag control arm is mounted to the bag support platform and permits installation of the bag pack on the mounting device when pivoted to a first, loading position and located to rest upon an outermost bag in the bag pack when pivoted to a second, control position. A surrounding control cage is attached to the dispenser to prevent a user from pulling a lower portion of the bag.
