Claims

[Claims for Utility Model Registration] The container body includes a container body in which a corona is formed in a part of an annular sealing rib surrounding an upper end opening, and the sealing rib is formed approximately along an imaginary circular arc with a radius R. (a) The angle θ formed by the tip of the coracoid is in the range of 60°≦θ≦130°, and (b) the sealing rib has an angle between the tip point A on the outer edge contour of the coracoid and the inner edge contour. The distance S between the tip points B in the seal peeling direction is in the range of (1/23)R≦S≦(2/17)R, and (c) the distance x on the inner edge contour circumference from the point B is O. Regarding the hypothetical opening range from to R, the width W of the sealing rib in the direction perpendicular to the seal peeling direction is
When the values taken at each point of n-1)/n}R are sequentially W ₁ , W ₂ ,...W _n (n≧5), (1/23)R≦W ₁ ≦(3/34)R For two existing and adjacent values of W, the following W
An easily openable sealed container characterized in that when the value of W increases from the previous value of W, the amount of increase does not exceed (1/4n)R.
