<p>PROBLEM TO BE SOLVED: To prevent bubbles from boiling over at the time of heat cooking by forming a flange joined to an upper end of a container main body, and further forming this flange into a shape of an inclined face so that the top end side of the flange is directed outward and positioned upward from the base end side thereof. SOLUTION: This container A made of an aluminum alloy foil, in which noodles, seasonings, etc., are contained, has a flange 2 provided jointly to the upper end of a container main body 1, and beads 5 are formed on the side wall 4 of the container main body 1. In this instance, the flange 2 extends from the shoulder 6 provided at an upper part of the container main body 1, and the top end side of the flange is positioned outside the shoulder 6 and formed into a shape of an inclined face extending upward. It is preferable that the flange 2 assumes an inclination angle of 10-45 degrees with respect to a horizontal level and also that the width of the flange 2 is 15-40 mm in a range of 10-40% of the length of an opening of the container main body 1. Further, wrinkles to be formed on the surface of the flange 2 are formed so as to exist in a direction different from the meridional direction.</p> |
