Problems solved by technology

In this way, also because of the short time available for forming, containers with, for example, sharp edges, sharp fold lines or precisely flat surfaces can only be produced with difficulty or only with low precision by blow molding.

Embodiment Construction

[0033] The invention is illustrated with reference to the drawings by way of example of a device set up for the high-pressure steam treatment of plastic containers produced according to the BFS method, the container walls of which have a special design. figure 1 A container 1 is shown having a configuration of a container body part 3 which deviates from conventional rotationally symmetrical contours, said container containing a filling. A circular head 5 is attached to the upper end of the body part 3, the upper closure of said head being formed by a membrane 7 bent slightly outwards. Said in use serves as an extraction region which may be pierced by a cannula, injection needle or infusion set. At this time, the shaped parting line 9 extending on the film 7 acts as a reinforcement of the film 7 to prevent involution during the piercing process, said shaped parting line is released from the blow mold after the container 1 produced by the BFS method formed during the molding pr...

Abstract

The invention relates to a method for the further shaping and / or shape stabilization of filled and closed containers (1), which are manufactured, in particular, in the blow-moulding, filling-and-seal process, said The method has at least the following steps: placing a corresponding container (1) into a receptacle, the wall (29) of which at least partially defines the contour, the container (1) being heated during the heat treatment be deformed onto the contour and conform to the contour in a form-fitting manner and / or conform to the contour in a form-stable manner by the overpressure thus generated in the interior of the container; and upon completion of the shaping and / or After the shape is stabilized, the corresponding container (1) is discharged from the receiving device.

Description

technical field [0001] The invention relates to a method and a device for the further shape stabilization and / or shaping of the faces and / or edges of filled and closed containers by means of overpressure inside the container during heat treatment, in particular It is a filled and closed container made of plastic material, which is manufactured by blow molding, filling and sealing. Background technique [0002] press also as The known blow-fill-seal (BFS) method of containers made of plastic, for example in the form of infusion bottles, is widely used especially for medical purposes. , such containers are therefore particularly suitable for medical applications, since the filling only comes into contact with the polymer, thus offering a high level of safety against microbial contamination even when the container is stored for extended periods in unfavorable environmental conditions. With the BFS method, a filled and hermetically closed bottle can be produced in less than 2...
