<p>PROBLEM TO BE SOLVED: To provide a nature-friendly container for packaging food, which can be incinerated by using polypropylene containing talc material so as not to generate environmental pollution and which is sufficiently strong even when thickness of the container is made thin and further costless. SOLUTION: This is a barrel-shaped packaging container for food, opened at the upper face and made from polypropylene containing talc material. The bottom face of the container body 1 is recessed inward from the outer peripheral edge of the bottom. And a projected leg 3 is formed at every specified distance along the outer peripheral edge so as to shape a recessed groove to correspond to the leg 3 at the inside bottom face. And a recessed part 7 and a protruded part 8 are alternately formed along the recessed groove 5 at the central bottom face 6 inner than the recessed groove 5.</p> |
