A folding carton formed from a blank of corrugated board, including first, second, third and fourth side walls hingedly connected by their edges to form a generally rectangular tubular enclosure, a bottom formed by at least two bottom walls hingedly connected to at least two of the side walls, and a top wall. The top wall is formed by first through fourth top cover flap hingedly connected at one edge to the first through fourth side wall respectively. Each of the top cover flaps is generally rectangular with the second top cover flap including ears extending from corners at the edge opposite the one edge and the first and third top cover flaps each including a notch corresponding to one of the ears. An adhesive is on one surface of the second top cover flap adjacent the opposite edge.

The invention claimed is: 1. A corrugated container formed from a blank, comprising: first, second, third and fourth side walls hingedly connected by their edges to form a generally rectangular tubular enclosure; a bottom wall for said enclosure between lower edges of the side walls; and a top wall formed by a first top cover flap hingedly connected at one edge to the first side wall, a second top cover flap hingedly connected at one edge to the second side wall, a third top cover flap hingedly connected at one edge to the third side wall, a fourth top cover flap hingedly connected at one edge to the fourth side wall, wherein each of said top cover flaps is generally rectangular with said second top cover flap including ears extending from corners at the edge opposite the one edge and said first and third top cover flaps each including a notch corresponding to one of the ears, said second and fourth top cover flaps have a spacing between their hinged one edge and their opposite edge, wherein said spacing is greater than half of the width of the first and third side walls by an amount generally equal to half of the spacing between edges of the ears, and said spacing between edges of the ears is substantially less than half of said spacing between said hinged one edge and opposite edge of said second top cover flap. 2. The corrugated container of claim 1, wherein said second top cover flap comprises a generally rectangular section and said ears extend from opposite sides of said rectangular section, and said ears are hingedly connected to said rectangular section. 3. The corrugated container of claim 1, further comprising adhesive on one surface of said ears. 4. The corrugated container of claim 3, wherein said adhesive comprises a continuous strip of adhesive on said ears and adjacent said opposite edge of said second top cover flap between said ears whereby said second cover top flap is securable by said adhesive to said fourth cover top flap with said ears securable by said adhesive to said first and third side walls. 5. The corrugated container of claim 3, further comprising a liner on said adhesive, said liner being selectively removable to expose said adhesive for securing said ears to said first and third side walls. 6. The corrugated container of claim 1, wherein said top cover flaps have a spacing between said hinged one edge and the opposite edge which is greater than half of the width of the first and third side walls. 7. The corrugated container of claim 1, wherein said blank is cut with a perforated connection between said ears and said first and third top cover flaps. 8. The corrugated container of claim 7, further comprising punched out holes between said ears and said first and third top cover flaps. 9. The corrugated container of claim 1, further comprising a tear off strip in said second top cover flap spaced from and parallel to said second top cover flap one edge and adjacent to but spaced from said ears. 10. A folding carton formed from a blank of cardboard, comprising: first, second, third and fourth side walls hingedly connected by their edges to form a generally rectangular tubular enclosure; a bottom formed by at least two bottom walls hingedly connected to at least two of said side walls; and a top wall formed by a first top cover flap hingedly connected at one edge to the first side wall, a second top cover flap hingedly connected at one edge to the second side wall, a third top cover flap hingedly connected at one edge to the third side wall, a fourth top cover flap hingedly connected at one edge to the fourth side wall, wherein the second top cover flap edge opposite said second top cover flap one edge has a width greater than said second side wall, the portion of said second top cover flap having a greater width than said second side wall has a width WE in the direction between said second top cover flap one edge and said second top cover flap opposite edge, said second and fourth top cover flaps have a spacing between their hinged one edge and their opposite edge which is greater than half of the width of the first and third side walls by an amount substantially equal to half of WE, and WE is substantially less than half of said spacing S; and an adhesive on one surface of said second top cover flap adjacent said opposite edge. 11. The folding carton of claim 10, a liner on said adhesive, said liner being selectively removable to expose said adhesive for securing said second top cover flap to said first and third side walls. 12. The folding carton of claim 10, wherein said second top cover flap has ears extending from opposite sides of said second cover flap defining said greater width. 13. The folding carton of claim 12, wherein said second top cover flap includes a generally rectangular portion and said ears extend from opposite sides of said rectangular portion, and said ears are hingedly connected to said rectangular portion. 14. The folding carton of claim 12, wherein said adhesive is on one surface of said ears. 15. The folding carton of claim 14, wherein said adhesive comprises a continuous strip of adhesive on said ears and adjacent said opposite edge of said second top cover flap between said ears. 16. The corrugated container of claim 10, wherein said blank is cut with a perforated connection between said ears and said first and third top cover flaps. 17. The corrugated container of claim 16, further comprising punched out holes between said ears and said first and third top cover flaps. 18. The folding carton of claim 10, further comprising a tear off strip in said second top cover flap spaced from and parallel to said second top cover flap one edge and adjacent to but spaced from opposite edge portion.
