Abstract
A single generally rectangular blank which can be formed into a paperboard package. The four corners of the blank are trihedral. The blank is center folded. The width of a first portion of the blank, measured parallel to the centerfold, is greater than a second portion of the blank. The blank is sealed on the two sides adjacent the centerfold to form an open package, which is then filled. The side opposite the centerfold is then sealed to close the package, forming a parallelepiped container. The seals are fin seals. The fin seal opposite the centerfold of the blank overlaps the two seals adjacent the centerfold. The three fin seals are folded flat against the sides of the package. The package may be provided with an opening through the blank. A tab may be provided to completely cover and seal around the opening in the package. The tab includes a grip portion which, when pulled upwardly, lifts the tab away from around the opening in the package. As the tab is pulled upwardly, an outer laminate layer tears away from an inner paper core of the package in the region of the seal between the tab and the package, uncovering the opening in the package. The tab will remain hingedly connected to the package along a rear tongue portion.
