Claims

[Claims for Utility Model Registration] A main body portion consisting of four side panels, first to fourth, separated by vertical fold lines and a joint panel provided on one side of the fourth side panel, and a common fold line. a bottom closure portion consisting of a pair of outer closure panels and a pair of inner closure panels separated from the main body portion by and located alternately below each side panel, the joining panel being heat sealed to one of the side panels; The outer and inner closure panels are assembled by laminating them together to form a container main body with a square cross section, and then folding the inner closure panel into a triangular shape along its diagonal fold line while folding the outer closure panels inward to each other. In a liquid paper container made from thermoplastic coated paperboard which is heat-sealed to form a bottom closure, the outer closure panel below the first side panel has a fold line in line with edge c of said inner closure panel. b, said inner closing panel has a fold-in flap 7' delimited by said diagonal fold lines d, e;
a fold line f that intersects with the common horizontal fold line a and is in equilibrium with the common horizontal fold line a; diagonal fold lines g and h connecting the intersection of the fold lines d and e with the fold line f and the outer corner of the inner closing panel; The diagonal fold lines g, h and the fold lines i, j form a triangular fold-in part, and the fold lines i, j, f form a substantially trapezoidal fold-in part and an inner closing panel. , the inner closing panels are folded inwardly toward each other along diagonal fold lines d and e, and the folded portions are folded outward along fold lines f, g, i, j, and h. The paper is characterized in that the outer closing panels are folded inwardly, and the folding flaps 7' are folded back outward along the fold line b, and the outer closing panels are stacked on top of the folded flaps. A paper container for liquids with a bottom whose edges are not exposed inside.
