Patent ID: 8657150

Claim:
A removable seal, comprising: an open position and a closed position; an upper body end of a container body and an edge portion of a lid, wherein in the open position the lid is insertable into the upper body end to form the closed position, wherein at the upper body end a terminal portion is bent outward by 180° providing a sharp body curvature, and an outer lid portion being radially spaced from a lid surface by a u-shaped channel and extending axially upward with a circumferential extending outer flank of the u-shaped channel and being bent outwards with a lid curvature being less than the sharp body curvature, the outer lid portion thereby forming a curved lid rim portion carrying an annular sealing material therein, the annular sealing material extending downwards, and wherein the lid rim portion has a free edge directed towards the outer flank, holding the annular sealing material and terminating at a radial distance from the outer flank, said radial distance allowing the sharp body curvature to enter into an interior of the curved lid rim portion in contact with the outer flank of the lid and the annular sealing material in the closed position, the terminal portion is being further bent radially to form a support shoulder comprising a shoulder surface rising radially outward and slanted upward suitable for supporting the annular sealing material in the closed position and further the terminal portion is bent axially downward from a peripheral radial end of the support shoulder, and then the terminal portion is rolled radially inward to create a curl outwardly adjacent to the upper body end.
