Abstract
A package (10) of a hollow rectangular parallelepiped shape is disclosed including a liner (14) inside of a carton (12). A first score line (72) extends from the free edges (47, 96) of the front and back top closure panels (48, 60) and onto the front and back panels (18, 28) parallel and intermediate the side edges (20, 22, 26, 30, 50, 52, 59, 64) thereof. Second and third score lines (74, 76) are further located in each of the front and back panels (18, 28) and extend at an obtuse angle from and on opposite sides of the first score lines (72), with the score lines (72, 74, 76) having a Y-shape. The bottom of the carton (12) holds the bottom edges (40, 44) of the front, back, and side panels (18, 24, 28, 32) in a rectangular configuration. With the top closure panels (48, 60) in an open condition, the top closure panels (48, 60) and the front and back panels (18, 28) can be flexed into a non-planar shape with the upper edges (48, 56, 62, 68) of the carton panels (18, 24, 28, 32) being open and generally of an oval shape allowing removal of ingredients from the liner (14) by a measuring cup which could not have been inserted into the top opening in a non-expanded, static condition.
