Set consisting of at least two containers, each of which has a different inner volume

A set comprising at least two containers each having different internal volumes, wherein the containers each has:

• a base,
• a casing adjoining the latter in an encircling manner, and
• an opening cross section which is defined by an end of the casing that faces away from the base and opens up access to the respective internal volume,
• wherein at least one wall portion of the respective casing runs at an inclination in relation to a vertical axis of the container, said vertical axis running perpendicularly to the base, in such a manner that an internal cross section of the container that is defined in each case by the casing decreases continuously from the opening cross section as far as the base, and the opening cross sections of all of the containers of the set are identical,
• characterized in that even the bases of all of the containers of the set are identical, and the at least one wall portion of the respective casing of all of the containers of the set in each case has
• a rectilinear portion in which, in each vertical projection plane parallel to a vertical axis of the container, the at least one wall portion leaves behind two trace lines which diverge toward the opening cross section, and each enclose an angle (α) between 2 degrees and 5 degrees, with the vertical axis, and
• a transition portion which is assembled from two arc portions and the intersection curve of which with each vertical projection plane parallel to the vertical axis of the container merges tangentially both into the rectilinear portion and into a respective intersection curve of the base, wherein an arc portion adjacent to the rectilinear portion has a greater radius than an arc portion adjacent to the base, and a different radius for each container of the set, and the two arch portions merge tangentially into each other.
