Carton and Blank thereof

Abstract

A carton for foodstuff, in particular for pizzas or similar foodstuffs, comprises a bottom part ( 2 ) and a lid part ( 3 ). Each of these parts ( 2, 3 ) has a front wall ( 4, 5 ) and two side walls ( 6, 7, 8 ). Bottom part ( 2 ) and lid part ( 3 ) are joined together pivotally by a rear wall ( 10 ) so that these parts ( 2, 3 ) are pivotable for opening and closing the carton ( 1 ). To stack cartons stably on top of one another in a simple manner and to prevent jamming of cartons arranged one above the other, at least one front wall ( 4, 5 ) of the bottom part ( 2 ) or lid part ( 3 ) runs obliquely outwards corresponding to a free end edge ( 11, 12 ) of the at least one front wall ( 4, 5 ).
