Abstract:
1. A carton, for a diagonally cut sandwich or like foodstuff, formed from a blank of card and having triangular end walls connected by rectangular side walls to form a triangular prism-shaped container, one said rectangular side wall of the container being hinged to another wall of the container to provide an opening for insertion/removal of foodstuff and to form a lid for closing the opening, the edges of the opening having out-turned flanges, and the periphery of the lid overlying the out-turned flanges encircling the opening when the lid is in closed position, whereby the lid can be bonded to the flanges to close the carton; wherein the carton is formed from a card which is heat sealable on the surface which forms the inner side of the container, the periphery of the lid of the container being bonded by heat sealing to the out-turned flanges encircling the opening to the container to seal the contents of the container and wherein the bonded lid/flanges are adapted to be torn apart to open the container for access to the food stuff therein by dual parallel lines of partial cut along the flanges, one being at the junction between the flange and the wall adjacent the inside face of the lid and the other part being way across and on the other side of the flange so that the flanges can split to allow the lid to be opened.
