Abstract:
The present invention relates to a disposable folding paper cup that folds flat and, when unfolded by the pressing of a folded portion, has a cylindrical upper end, the paper cup comprising: a cup body, which is made of a coated paper of which the inner surface is coated with a cup body coating layer, forms a cylindrical shape when unfolded, and forms a flat surface when both sides thereof are folded at folding lines; bending lines forming oval press parts that unfold bisymmetrically around each folding line when the folding line height center portion of the cup body is pressed, and dividing the oval press parts, spaced from the upper and lower ends of the cup body, therefrom; a bottom sheet which is a coated paper having a bottom sheet coating layer formed on the surface thereof so as to be fused with the cup body coating layer at the inner side of the lower end of the cup body, of which both ends are primarily fused therewith while the bottom sheet is folded along a transverse center folding line that is upwardly convex, and which is fused with the bottom edge of the folded cup body to form a bottom fused band; and fusion columns at which the front and rear surfaces, having the folding line at the center thereof, and the bottom sheet, having the end portion fitted therebetween, form a column shape higher than the fusion height of the bottom fused band and lower than the lower end of the bending line, thereby fusing, at a portion at which the bottom fused band and the folding line meet, the end portion of the bottom sheet through the three sides altogether.
