Claim Text:
1. A sample container, comprising: a housing which forms a sample space for receiving a sample and has at least one circular opening at one end which extends in an opening channel into the sample space, and a spherical closing element, wherein the diameter of the closing element only exceeds the diameter of the opening channel in at least one closing portion to such an extent that the closing element can be fixed in a force-locked manner by a largest circumference thereof in the at least one closing portion, wherein the closing element is spherical and in contact with the housing, and further wherein the opening channel from the at least one closing portion to an inner opening forms a protrusion, which reduces an opening cross section of the opening channel with respect to the opening cross section in the at least one closing portion, and further wherein the opening channel from the at least one closing portion to the at least one circular opening forms a further protrusion, which reduces the opening cross section of the opening channel with respect to the opening cross section in the at least one closing portion, wherein the distance from the further protrusion to the protrusion permits a positioning tolerance of the closing element of from 0.7 mm to 5 mm, and wherein the housing is formed in a tapering manner at a second end.
