Abstract
Abstract A carton with a reclosable hinged cover formed by laterally spaced cut score lines in its top panel and front glue flap. The cut score lines in the glue flap flare upwardly to form arrow locking tabs which may be pushed through the cover opening so that the shoulders of the tabs lock under the front edge of the top panel. In the preferred form, the cut score lines forming the shoulders of the locking tabs extend only a portion of the way through the thickness of the paperboard and the cut score lines forming the cover portions in the top panel and glue flap are of the inside-outside double cut score type which provides partial thickness locking tabs and an overlapping cover.
