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 and a connecting piece forming an inner channel and via which a 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 widening region that widens substantially conically within the longitudinal portion of the connecting piece, starting from the container interior.
A medical fluid container comprising a connecting piece forming an inner channel and via which a container interior is accessible from outside the medical fluid container, the connecting piece having an outer thread on a longitudinal portion of the connecting piece, the connecting piece being formed exclusively by calibrating material insertion, the connecting piece pressing a container blank in a region of the connecting piece against a die having a longitudinal portion of the outer thread.
A method for forming a medical fluid container comprising the steps of:
- providing a container blank that is substantially unprofiled and cylindrical;
- inserting a blow pin into the container blank;
- inserting the container blank into a die using the blow pin;
- pressing the container blank against the die exclusively by mechanical pressing to produce a connecting piece using the blow pin;
- and
- shaping a container interior pneumatically by blowing pressurized gas into the container blank using the blow pin.
