CA 2179395
A gable top carton employs a stake seal (90) having spaced apart legs (95) disposed longitudinally on opposite sides of a channel, the channel being formed when a carton blank is folded to form the gable top carton. The spaced apart legs urge the material at the sides of the channel toward the center of the channel to effect a channel seal. The stake seal may be in the form of an inverted U-shaped stake seal. A method and apparatus for forming the stake seal are also contemplated.
