Abstract

A fully enclosed carton having top, bottom and spaced sidewalls foldably joined along their side edges to form a tubular structure is provided with a longitudinal partition panel foldably joined to the bottom and top walls and the ends of the carton are provided with end closures which are of a composite construction. Each end closure comprises top and bottom end flaps foldably joined to the top and bottom walls respectively together with side end flaps which are foldably joined together in flat face contacting relation to close the carton ends. A pair of transverse weakened severance lines are formed in spaced relation in the top wall and in the upper portions of the sidewalls to provide a handle for the carrier and a reinforcing panel is struck from the top portion of the partition panel and folded into flat face contacting relation with an interior surface portion of the top wall so as to afford reinforcement therefor.

Claims

1. A carton comprising a bottom wall, a top wall including an inner top wall panel and an outer top wall panel, a pair of sidewalls foldably joined to the side edges of said bottom wall, said inner top wall panel foldably joined to the top edge of one of said sidewalls and having its opposite inner edge disposed medially of said top wall longitudinally thereof, a longitudinal partition panel foldably joined to the inner edge of said inner top wall panel and having its bottom edge foldably joined to said bottom wall medially thereof, said outer top wall panel foldably joined to the upper edge of the other of said sidewalls and secured in face contacting relation to said inner top wall panel, and a reinforcing panel struck from the top portion of said partition panel and disposed in flat face contacting relation to the inner surface of said outer top wall panel and disposed on the opposite side of said partition panel from said inner top wall panel and forming therewith a two-ply reinforcement for a portion of said top wall.

2. A carton according to claim 1 wherein spaced apart severance lines are formed in said top wall transversely thereof and arranged to extend downwardly into the upper portions of said sidewalls and defining therebetween a handle structure having a least one hand gripping aperture therein.

3. A carton according to claim 2 wherein said severance lines coincide approximately with the end edges of said reinforcing panel whereby the portion of said handle structure which is formed from said top wall is to of two-ply construction.

4. A carton according to claim 2 wherein a pair of longitudinal tear strips are formed in said top wall substantially medially thereof, each tear strip extending from one of said severance lines to the adjacent end edge of said top wall whereby access to the interior of the carton is afforded without severing other parts of the carton.

5. A carton according to claim 2 wherein top end flaps are foldably joined to the end edges respectively of said outer top wall panel along weakened severance lines, each top end flap forming a portion of an end closure for one end of the carton. 6, A carton according to claim 5 wherein a side end flap is foldably joined to each end edge of both of said sidewalls and wherein a bottom end flap is foldably joined to each end edge of said bottom wall, said top and bottom end flaps being secured in flat face contacting relation with said side end flaps at each end of the carton to form an end closure therefor which is severable from the end edges of said outer top wall to afford access to the interior of the carton without rupturing said end closures.
