<p>PURPOSE:To embody the low-cost production and easy and safe opening from a part near the ends of half-cut lines and along the half-cut lines, by making the half-cut lines in the edges of outward projections and along the inside of the part where the edges of the outward projections are joined. CONSTITUTION:A pair of half-cut lines 6.6 upper and lower, are made along the inside of a hinge part 3, that is, the part where the edge 7.7 of the outward projection of a containing body 1 and the edge 7.7 of the outward projection of a cover 2 are joined together. The half-cut lines 6.6 serve as the folding lines of the hinge part 3 as well. In the state of the pack container sealed by folding the container into two from the hinge part, its upper part exactly over its lower part, the hinge part 3 is folded along the half-cut lines 6.6 and the part where the edges 7.7 of the outward projections, opposite the hinge part 3, are superimposed is sealed by heat seal 9 for joining. To open the container, a part 3A between the half-cut lines 6 of the hinge part 3 is pulled outward from a notch 8, and the hinge part 3 can be opened along the half-cut lines 6.6.</p> |
