Abstract
Thermoformed cups, having elements adapted to provide a stable handle, which are nestable in a small space, the handle including a tab extending radially from the brim of the cup and a hinged flange at each side of the tab. To form the handle the flanges are turned down and are retained by shoulders of a recess in the upper surface of the cup. Weight of liquid in the cup causes the flanges to bear against the side of the cup to afford stability in addition to that resulting from retention by said shoulders.
Claims7
A nestable thermoformed cup and handle means formed integrally therewith in such fashion as to not interfere with nesting of stacked cups and to form a stable handle upon movement of the handle means to operative position comprising:
- a. a cup body having an upper brim portion, a bottom of smaller dimension than said brim portion and sides tapering inwardly from said brim portion to said smaller bottom;
- b. a tab integral with the upper edge of said brim portion extending outwardly therefrom and normal thereto;
- and
- c. a flange integrally hinged to each side of said tab and having an inner edge adjacent to and free of the brim portion, said inner edge being immediately adjacent the brim at its point of attachment to the tab and shaped to conform to the inwardly tapering side of cup body so that when the flanges are folded downwardly substantially the entire length of each inner edge will contact the side of the cup body to provide an elongated bearing surface against the body.
