A food carton formed from a unitary blank of foldable paperboard comprising:
- a bottom tray;
- a top cover;
- and hinge means connecting said bottom tray to said top cover;
- said bottom tray comprising:
- a substantially trapezoidal base panel;
- a front closure panel, a lower back panel, and a pair of lower side panels, each hingedly connected to, and extending from, said base panel;
- said top cover comprising:
- a substantially rectangular top panel;
- a substantially trapezoidal upper front panel, an upper back panel, and a pair of upper side panels, each hingedly connected to, and extending from, said top panel;
- wherein the upper front panel extends substantially to the junction of the front closure panel and the base panel and the upper side panels partially overlie and frictionally engage the upper edges of the lower side panels whereby a heat and vapor trap is provided when the carton is in a closed position, and the carton is nestable with similar cartons when said cartons are stacked in an open position.
A unitary blank being suitably cut and scored and adapted to be erected into a nestable carton for a food product, said blank comprising a bottom tray-forming section;
- a top-cover forming section, and a score line hingedly connecting said bottom tray-forming section to said top cover-forming section;
- wherein said bottom tray-forming section comprises a substantially trapezoidal base panel, a pair of lower side panels hingedly connected to a first pair of opposed edges of said base panel, a front closure panel and a lower back panel hingedly connected to a second pair of opposed edges of said base panel;
- and a pair of first glue flaps hingedly connected to opposed side edges of said lower back panel;
- wherein said top cover-forming section comprises a substantially rectangular top panel, a pair of upper side panels hingedly connected along a first pair of opposed edges of said top panel, an upper back panel and a substantially trapezoidal upper front hingedly connected to a second pair of opposed edges of said top panel, a second pair of glue flaps hingedly connected to proposed side edges of said upper back panel, and a third pair of glue flaps hingedly conected to the edges of said upper side panels;
- and
- wherein said top cover-forming section is adapted to partially overlie and frictionally engage the bottom tray-forming section when the blank is erected into a carton and the carton is in a closed position.
