ABSTRACT:
A one-piece T-shaped carton blank is disclosed which is utilized to form a rectangular cross-sectional container having its top and bottom end panels sealed in a plane substantially perpendicular to its sidewalls. The carton blank is formed having a definite dimensional relationship between its end panels and side panels to provide improved nesting of multiple carton blanks upon paperboard sheet stock in an alternating inverted side-by-side relationship. A pair of end sealing tabs extend along the top and bottom edges of the blank side panels. One of the end sealing tabs is separated from the top end panel and from a side sealing tap to prevent tearing and to permit the complete welding of the side sealing tab up onto the top end closure panel of the carton blank. This separation of the end sealing tab in combination with displacement of the hinge line of the top end closure panel downward provides a liquid-tight corner seal for the carton. Further, an improved method of scoring and bending of the carton blank is provided.
