<p>PURPOSE:To obtain a low cost self-standing type disposal package container, by providing a specified cut or groove in a plane single sheet material and spirally deforming it to give the retaining characteristic of self-standing function to the container. CONSTITUTION:This container A is provided with a circular brim 10 extended outward at the upper end and a circular plane bottom wall 11 at the lower end and further, a number of side wall belts 12 are provided between the circular brim 10 and the circular plane bottom wall 11 in order to connect these. The side wall belts 12 are torsioned outward through respectively isolated intervals 13 and arranged between the circular brim 10 and the bottom wall 11 to be curved and slant. Since the circular brim 10 and the bottom wall 11 are vertically held with a certain distance in these numerous side wall belts 12, the retaining characteristic of self-standing function is provided to this container A. And this container A is formed by spirally deforming the single sheet member B provided with the outer peripheral edge 10a, the base 11a inside the face, and a number of radially curved connection belts 12a partitioned by the cut 12a therebetween.</p> |
