Cartons and blanks for forming cartons

Claim 1

A carton having side walls, respective end flaps attached to each end of each side wall to provide the top and bottom of the carton and a preformed lining sleeve fastened into the carton for protrusion beyond the ends of the side walls thereof, a pair of opposed end flaps at one end of the carton being disposed in face-to-face relation in the closed condition of the carton, the upper of said pair of end flaps being formed with a pair of lines of weakness whereby, to open the carton, a user may effect a separation operation along said lines of weakness, thereby providing a tab for engagement in a slot in the lower end of said pair of end flaps for effecting reclosure of the carton, and the lower of said pair of opposed end flaps extending between and being hingedly connected to a pair of opposed end flaps which are so shaped and have fold lines so arranged that each can be folded inwardly in such way that a triangular part based on the fold line between the flap and the adjoining side wall of the carton is overlapped by a pair of parts of the flap which are doubled back on a fold line, said lower end flap and the pair of end flaps hingedly connected thereto serving, on closure of the carton, to shape the end of the lining sleeve with a pleat in each side and to fold it over to nip a pleated end extremity of tHe lining sleeve against the upper end flap at its hinged connection with the adjoining side wall of the carton and wherein the pair of lines of weakness each extend from a corner of the side wall adjoining said upper end flap at an inclination to the line of juncture between the end flap and the side wall, that portion of the end flap between the lines of weakness constituting a tab-defining portion.
