An icing implement includes a collapsible bulb-shaped container (12) with an enlarged discharge mouth (26), a discharge nozzle (16) and an adapter collar (14) interposed between the enlarged container mouth (26) and the relatively restricted internal passage of the nozzle to effectively seal to both and provide for movement of icing from the container to the nozzle upon an axial compression of the bottom (18, 22), of the container upwardly and inwardly into the interior of the container. The provision of circumferential grooves (34) on the container, with the graded spacing between the grooves, ensures that the collapse of the container (12) is effected in equal volume increments with the container retaining its collapsed position. |
