<p>A container for fluid mixable food products is provided with a lid (10) made of a flexible sheet material and comprises a hollow body (1) which is provided with a bottom (2) and formed by two sheet material layers which are connected to each other in such a way that a hollow truncated cone is formed. A least the internal layer (3) is made of a cellulose-based material, preferably coated paper. The height of the involute of the internal layer (3) is greater than the involute of the external layer (4) at least at the sum of the arc length value of the cross section of a flange (5) formed by folding the internal layer, in the top part of the body, on the external layer by overlapping it and the value of the internal layer lower part folding on the bottom fold (6) by overlapping it in such a way that a sealed lock connection (7) between the bottom and body is formed. The junction (8) of the internal layer and the junction of the external layer are shifted to each other along the body circumference at a value which is equal to or greater that 1/15 the circumference of the top part thereof. The ratio between the body top and bottom diameter is equal to (139±0.5)(103.4±0.5) and the body cone is embodied at an angle of (7.95±0.5)°.</p> |
