The invention claimed is: 1. A nestable cardboard container (1), having a downwardly tapering conical inner wall (2) and a downwardly tapering conical outer wall (7), said walls being joined at the upper rim of the container, said outer wall (7) at its lower end resting against the outside surface of the inner wall (2) with an inwardly turned edge (8) so as to form an air gap between said walls, the inwardly turned edge (8) being located at a distance above the bottom rim of the container, the inner wall (2) having an inwardly protruding creasing (4) extending in the circumferential direction, said creasing being located above the bottom of the container thereby forming an abutment for the inwardly turned edge (8) of a nesting further container, the arrangement of the inwardly turned edge (8) and the inwardly extending creasing ( 4) being such that in the nested state the inner nested container is maintained in position in the outer container without making the outer wall (7) of the inner container adhere to the inside surface ( 3) of the inner wall (2) of the outer container. 2. A process for manufacturing a cardboard container (1 ), which comprises the following steps: providing a blank (1), arranging said blank (1) on a revolving supporting member (5) having a perimetral groove and form an inner wall ( 2) of said cardboard container(1), forming a perimetral inwardly projecting creasing (4) distant from a bottom rim of said container inner wall (2) with a related complementary knurl (6) adapted to co-operate with said perimetral groove of said revolving supporting member (5), fixing an outer wall (7) on the outer side of said container inner wall (2) with an air gap formed between both walls (2, 7), the outer wall (7) having a lower inwardly turned edge (8) situated nearer to said inner wall bottom rim than said creasing (4); wherein said inner wall (2) and outer wall (7) are downwardly tapering and conical, said walls being joined at the upper rim of the container, said outer wall (7) at its lower end resting against the outside surface of the inner wall (2) with said inwardly turned edge (8) so as to form said air gap between said walls, the inwardly turned edge (8) being located at a distance above the bottom rim of the container, said inwardly protruding creasing (4) extending in the circumferential direction, said creasing being located above the bottom of the container thereby forming an abutment for the inwardly turned edge (8) of a nesting further container, the arrangement of the inwardly turned edge (8) and the inwardly extending creasing (4) being such that in the nested state the inner nested container is maintained in position in the outer container without making the outer wall (7) of the inner container adhere to the inside surface (3) of the inner wall (2) of the outer container.
