<p>A single generally rectangular blank which can be formed into a paperboard package (10). The four corners of the blank are trihedral. The blank is center folded and sealed on the two sides (13, 14) adjacent the centerfold to form an open package, which is then filled. The package is then closed to form a parallelepiped container. The package may be provided with an opening through the blank. A tab (17) may be provided to seal the opening in the package. The tab includes a grip portion (17c) which, when pulled upwardly, lifts the tab away from 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.</p> |
