Abstract
Abstract A take out carton and a blank for forming the same is disclosed having a gabled top portion and unique locking closure which provides additional stability for the carton. More particularly, a carton is disclosed having a tubular side wall and an auto-erecting lock bottom. The subject carton further includes a pair of opposed top panels, each having a pair of tab receiving apertures disposed adjacent the side edges thereof. A pair of opposed closure panels are provided each including a base triangle and two side triangles. Each side triangle further includes a central fold line defining a pair of minor triangular portions. The carton has a generally inverted truncated pyramidal configuration to permit stacked nesting of the plurality of cartons. In the closed condition of the carton, the top edges of the top panels are in abutting relationship to define the gabled top configuration. Each side triangle of the closure panels is folded about its central fold line to define a double ply closure tab which is rotatable into coplanar relationship with the top panel. A portion of each closure tab is interengaged with a tab receiving aperture in a top panel to secure the carton in the closed position. The cooperation between the closure tabs and the tab receiving apertures in the top panel functions to provide increased stability for the carton and inhibits the relative shifting between the top panels thereof.
