A device for applying a stretch film lid to a cup has a planar stretching member, including a relatively rigid peripheral portion, and a multiplicity of finger elements spaced thereabout and extending inwardly therefrom. The finger elements are readily displaceable from the plane of the stretching member, and define, upon displacement, a passageway configured to permit the cup to pass through. Securing means is engageable with the stretching member to secure a stretch film thereto. When a cup is urged against the stretching member, it displaces the finger elements, thereby defining the passageway, with the finger elements and securing means cooperating to extend the stretch film along a plurality of axes, to permit the application of the stretched film to the cup. |
