Abstract
A nestable, stackable container comprised of a tray preferably erected from carton blank and having cut-away portions defined at the ends thereof, a tray of plastic film is formed within the carton tray through a deep drawn process in which the upper end of the film tray is folded over the upper edge of the carton tray. The film tray is extended outwardly through the cut-away end portions to form a pair of stacking lips which serve to prevent nested containers from becoming wedged into one another.
Claims5
A nestable, stackable container comprising a generally conical-shaped tray (2) of a carton provided with a tray (3) of plastic film which is in contact with the interior of the carton tray (2), said plastic tray (3) being deep drawn into the carton tray (2) and extending over and around the upper edge (8) of the carton tray (2) and a short distance downwardly along the exterior of the carton tray (2), characterized in that each end wall (5) of the carton tray (2) comprises a centrally situated cut-away portion (4) at the upper edge (8) of said end walls (5), through which portions of material from said plastic tray (3) are pressed outwardly so as to extend beyond the exterior of the carton tray (2) and thereby form a stacking lip (9), said stacking lip (9) being adapted to engage the upper edge (8) of a like container (1) situated there-below when stacking a number of such containers (1) such that a space is provided between the bottom walls (11) of adjacent containers to thereby prevent the container from becoming wedged or jammed when nested into another container.
A nestable, stackable container comprising:
- a generally conical-shaped carton tray (2) including a base (11) having side edges (12a, 13a) and end edges (14a), a pair of side walls (12, 13) extending from said side edges, and a pair of end flaps (14) extending from said end edges, said side walls having extensions which form, in conjunction with said edge flaps, the end walls of said container, the length and height of said end flaps and said side walls being adapted to form a centrally situated cut-away portion adjacent the upper edge of each side wall when said carton blank is formed into said carton tray (2);
- a tray (3) of plastic film which is deep drawn into said carton tray (2) and which extends over and around the upper edge (8) of the carton tray (2) and a short distance downwardly along the exterior of said carton tray (2), portions of material from said plastic tray (3) being pressed outwardly through said cut-away portions (4) so as to extend beyond the exterior of said carton tray (2) and thereby form a stacking lip (9).
