<P>PROBLEM TO BE SOLVED: To provide a gable-top easily unsealable paper container capable of satisfying two conflicting functions of sealability and unsealability and fully opening a top. <P>SOLUTION: A top seal of a gable-top paper container is formed, using a laminate consisting of an outer layer, an intermediate layer mainly comprising paper and an inner layer, by folding respectively a pair of opposite end panels connected with upper sides of side panels of a rectangular parallelepiped barrel consisting of the four side panels inwardly via slant creases, concurrently two-folding an inner rib panel connected with the upper side of the end panel via a center crease, then, in conjunction with the former step, falling another pair of opposite roof panels inwardly, falling an outer rib panel connected with the roof panels concurrently, and butt-seam-sealing the outer rib panel with two-folded inner rib panel interposed. The top is formed in the form of a gable top, thereby obtaining the gable-top paper container. An unsealing piece to be pinched between fingers to unseal the top seal for fully opening the top is provided on the upper side of the pair of opposite outer rib panels, thereby providing the easily unsealable paper container. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
