Claim:
1. A container having an oval cross section with first and second narrow sides, said container comprising: (a) a lower part comprising an outer face; (b) an annular latching engagement part comprising first and second latching engagement part strips extending vertically upward and downward and peripherally in a horizontal orientation so as to surround the lower part and form first and second peripheral clearances in a horizontal plane; and (c) a cover part comprising a downward projecting latching portion cooperating with the latching engagement part; wherein the latching portion comprises opposing first and second latching tongues having respective first and second inner faces positioned on the first and second narrow sides, respectively, and extending along the lower part below the latching engagement part; wherein the first and second latching tongues comprise respective first and second vertical longitudinal extensions, respective first and second widths, and respective first and second lower end faces and extend in a curved manner transverse to the first and second vertical longitudinal extensions, respectively; wherein in a closed position, first and second direct clearances are formed between the respective first and second inner faces and the outer faces so as to extend entirely over the first and second widths, respectively, and in a respective region of the first and second lower end face; wherein the lower part is releasable from the latching engagement part by freely moving the first and second latching tongues simultaneously toward the outer faces to lift the cover part; and wherein the first and second peripheral clearances extend circumferentially in the horizontal plane from respective first and second regions of cooperation between the latching engagement part and the first and second latching tongues and the first and second peripheral clearances taper normal to the outer face of the lower part from the respective first and second regions of cooperation to respective first and second minimum dimensions over a distance equal to one tenth to one third of a maximum inner diameter of the oval cross section.
