ABSTRACT:
A sealed container eventually shaped into a rectangular parallelopiped is formed by folding a sheet of blank and joining together the required folded portions. The container has a longitudinal seal portion formed by joining together the longitudinal opposite edge portions of the blank and extending vertically over the rear side of the rectangular parallelopipedal container main body, and upper and lower transverse seal portions formed by sealing the upper and lower ends of the blank as shaped in the form of a tube. The upper and lower seal portions extend sidewise over the top side and bottom side of the main body, respectively, and are folded toward the rear side.
