<p>A container for fluid mixable food products is provided with a lid made of a flexible sheet material and comprises a hollow body (1) which is provided with a bottom (2) and whose external (3) and internal (4) surfaces are formed from two segment-like sheet material layers which are connected to each other in such a way that flanges (5, 6) are formed along the top and bottom perimeters thereof, respectively, and each of which forms a hollow truncated cone, wherein at least the internal truncated cone is made of a cellulose-based material, preferably a coated paper. The bottom is sealingly connected with the sidewalls by folding (7) the lower part thereof. The arcs (8, 9) of said segment-like layers have a central angle ranging from 45 to 50° and are tensioned along the external perimeter thereof by a chord whose length ranges from 440 to 460 mm and along the internal perimeter by a chord whose length ranges from 350 to 370 mm, wherein the conicity of the external side surface is greater than the conicity of the internal side surface. Said invention makes it possible to increase the rigidity and operation reliability and to protect a user against a burn from the bottom or the container walls.</p> |
