In particular, no waste is produced by this mode of production, which must be recycled or disposed of with a corresponding expense. The production costs each produced tube-like body can be reduced thereby.
- a severing is carried out perpendicular to a center line of the primary body, but it can be given here depending on the application obliquely to the center line dividing planes.
- the production of a smooth cutting edge is not necessarily specified, but depending on the cutting tool used, the contour of the edge can be adapted to the respective production requirements or the respective product design optimized. For example, it is possible to make the contour wave-shaped, whereby a freshness or cold effect is suggested.

- the first mouth region (21) is closed by a dome (56), which has been produced by injection molding and in one piece with the remaining region of the preform (1).
- the mouth sections (21) are each separated by a support ring (57) from a side wall (58) of the preform (1).
- An inner space (59) of the preform (1) has an inner diameter (60) and on the outside, the preform (1) is provided with an outer diameter (61).
- the side wall (58) has a wall thickness (62).
- the preform (1) is of an inner surface (63). and the inner surface (63) opposite to an outer surface (64) limited.
- the stretching rod (11) When performing a stretching operation, the stretching rod (11) is inserted through an opening (65) delimited from the second opening region (21) into the interior space (59) and in this case abuts against the inside of the dome (56). In a further implementation of the stretching movement, the stretching rod (11) pushes the dome (56) in front of it and thereby causes the stretching of the preform (1).
- the dome (56) is provided with sufficient wall thickness to absorb the applied mechanical forces.
- it is intended to provide the stretch rod in the region of a stretch rod tip with a sufficiently large cross-sectional area in order to support a uniform introduction of force into the dome (56).
- the stretching rod may optionally be provided with suitable stretching bar attachments to optimize the stretching process. For example, the use of a Reckstangenkuppe made of a plastic is intended.
- a pulling device acting on the outside at the first mouth section (21) can also be used.
- FIG. 8 Shown in FIG. 8 is also a typical parting plane (66) which defines the positioning of the cut edges (49) shown in FIG. 5 with regard to the finished primary body (2).
- FIG. 9 shows a more detailed representation of the blow mold (4) with bottom part (7) than in the schematic illustration in FIG. 2. It can be seen in particular that the bottom part (7) for receiving the first mouth portion (21) has a trough-like depression (67).
- the depression (67) is preferably contoured so that the preform (1) rests with its mouth portion (21) and the tip (56) after insertion into the bottom part (7) on an inner wall of the recess (67).
- this preferably has an interior design which is adapted to an outer contour of the mouth section (21).
- the recess (57) has a circular cross-sectional area transverse to the longitudinal axis (55). A deformation of the mouth portion (21) by the acting blowing pressure can be avoided thereby.
- the recess (67) typically has a configuration such that the ring portion (71) has an inner diameter which essentially corresponds to an outer diameter of the support ring (57).
- the annular section (71) is led from the shoulder (68) into a section of the depression (67) which has an inner diameter substantially equal to an outer diameter of the mouth section (21) and smaller than the inner diameter of the annular section (71) is.
- a cartridge according to FIG. 7 using a preform according to FIG. 8 is advantageous in particular because cartridges usually have a sealed mouth section (21) prior to their use, which is prevented by the tip (56) from being emptied. is opened.
- the use of a preform (1) according to FIG. 8 for the production of cartridges thus makes it possible to produce cartridges which largely correspond to today's cartridges with regard to their design and handling. There are thus no changes in the established steps required when using the cartridge. In a largely maintaining all current constraints but still a cartridge is provided which has a much smaller wall thickness than cartridges according to the prior art and thus cheaper to manufacture and leads to their intended use to a reduced amount of waste.
- the dome (56) of the preform (1) shown in Fig. 8 it is also possible to temporarily provide the first mouth portion (21) with a closure suitable for receiving the stretching forces during the stretching operation.
- a blastchnischen deformation of a primary body (2) with a substantially to the separation plane (66) mirror-symmetric material distribution is especially thought to perform a suitable temperature of the preform (1) in the direction of the longitudinal axis (55) such that due to the implementation of the stretching process and / or the blowing process otherwise caused material irregularities are compensated.
