Abstract
A medical fluid container includes a container interior and a connecting piece that forms an inner channel. The container interior can be accessed from the outside via the connecting piece. The connecting piece has an outer thread on a connecting piece longitudinal section. The inner channel expands in a substantially conical manner in a region of the outer thread, starting from the container interior, to then preferably transition into a first cylindrical channel shape which extends to a free opening of the connecting piece. A method can be used for producing the medical fluid container from a container blank.

A medical fluid container comprising:
- a container body having a container interior;
- a connecting piece adjacent to the container body along a center axis, the connecting piece forming an inner channel via which the container interior is accessible from outside the medical fluid container, the connecting piece having an outer thread over a longitudinal portion of the connecting piece, the inner channel having a first region having a first inner diameter, a second region spaced along the center axis from the first region and having a second inner diameter that is smaller than the first inner diameter, and a widening region that extends between the first region and the second region and widens substantially conically from the second inner diameter to the first inner diameter;
- and
- a bead geometry located between the second region and an end of the container body having a third inner diameter, wherein the bead geometry comprises a bulge that extends radially outwardly from the center axis and has a fourth inner diameter that is larger than the second inner diameter and larger than the third inner diameter.
