Claims

[Claims for Utility Model Registration] (1) A rectangular top panel, a bottom panel, and a pair of side panels are created by bending a blank plate having parallel fold lines along each fold line, winding it, and gluing both ends. The body has a rectangular vertical cross-sectional shape, and rectangular inclined panels are connected to both ends of the upper panel and the lower panel, and outer rib panels are connected to each inclined panel. , at both ends of each of the side panels, inward folding panels in the form of an isosceles triangle with an acute apex angle are arranged in series on the base side thereof, and on each oblique side of each of the inward folding panels, there is a panel at right angles to the adjacent inclined panel. A pair of right-angled triangular in-fold small panels are each connected on the long sides of the in-fold small panels, and are connected on the sides opposite the right angle, and are adjacent to each other on the short sides of the in-fold small panels that sandwich the right angle. The inner rib panels are connected to each of the outer rib panels, and each of the inward folding panels is folded inward and the pair of inward folding small panels connected thereto are folded in, and at the same time, each of the inclined panels is folded. Side closing portions having the same shape are formed on both sides of the body by slanting inward and sandwiching and gluing each of the inner rib panels between the outer rib panels to form a horizontal rib portion. and sealed paper carton. (2) The sealed paper carton according to claim 1, further comprising a window hole formed in the top panel and a transparent film member for closing the window hole. (3) A synthetic resin film layer having tearability in one direction is provided on the inside of the paper layer constituting the blank board in such a manner that the tear direction goes around the body, and the blank becomes the outside when wound. 3. The sealed paper carton according to claim 1, further comprising a grip portion formed by protruding a portion including the synthetic resin film layer from one side end of the plate.
