An icing implement including a collapsible bulb-shaped container with an enlarged discharge mouth, a discharge nozzle and an adapter collar interposed between the enlarged container mouth and the relatively restricted internal passage of the nozzle to effectively seal to both and provide for movement of material from the container to the nozzle upon an axial compression of the bottom of the container upwardly and inwardly into the interior of the container. The collapse of the container is effected in equal volume increments with the container retaining its collapsed position.
