Abstract

A method for producing a sterilized container comprises: providing a preform having a hanger arranged on a bottom of the preform, heating the preform in a heating device, feeding the heated preform into a stretching and blowing apparatus, stretching and blowing the preform in the stretching and blowing apparatus such that the container for the infusion solution is formed from the preform, cleaning the formed container in a rinsing apparatus, and drying the cleaned container in a drying device, filling the cleaned and dried container at least with an infusion solution, via a filling opening present in the container, in a filling plant, closing the container by attaching a closure cap to the filling opening of the container, sterilizing the closed container in an autoclave, wherein the hanger of the preform is oriented and folded over by a bending apparatus prior to stretching and blowing in the stretching and blowing apparatus.

First claim

The invention claimed is:

1. A system for producing a container filled with an infusion solution, the system comprising:
a first installation for providing a preform having a hanger disposed on a base of the preform;
a heating installation for heating the provided preform;
an apparatus for stretching and blowing the preform such that the container for the infusion solution is moldable from the preform;
a second installation for cleaning the molded container, wherein the second installation is configured to dry the cleaned container;
a filling system in which the cleaned and optionally dried container by way of a filling opening which is present in the container may be filled at least with one infusion solution;
a third installation for closing the container;
an autoclave in which the closed container is sterilizable;
a first conveying installation for guiding the preform in the heating installation and for infeeding the heated preform to the stretching and blowing apparatus in which the preform may be rotatably mounted and aligned by way of rotation, and a bending apparatus which is disposed ahead of the stretching and blowing apparatus and in which the preferably pre-aligned hanger of the preform may be turned over.

2. The system as claimed in claim 1 , wherein
the first conveying installation has at least one movably disposed rotary pin on which the preform is mountable and by way of which rotation of the preform is providable, and/or
the bending apparatus is providable by an edge which is disposed ahead of the stretching and blowing apparatus, for example in or after the heating installation-and which in relation to the first conveying installation is disposed so as to be locationally fixed and laterally offset such that the hanger of the preform by means of a movement of the first conveying installation may be moved against the edge, be brought to bear and bent thereon.

3. The system as claimed in claim 1 , wherein the first installation is configured to provide the preform aligned such that a transverse axis (Q H ) of the hanger lies so as to be substantially transverse.

4. The system as claimed in claim 3 , wherein the first installation is configured to provide the preform aligned such that a transverse axis (Q H ) of the hanger lies perpendicularly to a movement direction (X) of the preform.

5. The system as claimed in claim 1 , wherein the first installation is configured to provide the preform such that the hanger of the preform is placed away from a longitudinal axis (L) of the preform in the direction of the base of the preform.

6. The system as claimed in claim 1 , wherein the first installation is configured to align the preform such that a transverse axis (T) of the container is disposed in the heating installation so as to be substantially transverse.

7. The system as claimed in claim 6 , wherein the first installation provides the preform perpendicularly to a movement direction (X) of the preform.

8. The system as claimed in claim 1 , wherein the heating installation is configured to heat the preform such that two mutually opposite regions of the preform that extend in the direction of a first transverse axis (B) of the container molded from the preform are heated more intensely than two mutually opposite regions of the preform that extend in the direction of a second transverse axis (T) of the container molded from the preform.

9. The system as claimed in claim 1 , wherein the heating installation is configured to heat the preform such that the preform along a circumference thereof is heated in a substantially uniform manner, and a first set of two mutually opposite regions of the preform that extend in the direction of a first transverse axis (B) of the container molded from the preform are provided with a thinner wall thickness than a second set of two mutually opposite regions that extend in the direction of a second transverse axis (T) of the container molded from the preform.

10. The system as claimed in claim 1 , wherein the heating installation is configured to initially heat the preform, such that, at least in a region that forms the main body of the container molded from the preform, is heated in a substantially uniform manner, and two mutually opposite regions of the preform which then provide the sides of the container molded from the preform which extend in the direction of a first transverse axis (B) prior to infeeding to the stretching apparatus and the blowing apparatus are heated more intensely.

11. A system for producing a container filled with an infusion solution, the system comprising:
a first installation for providing a preform having a hanger disposed on a base of the preform;
a heating installation for heating the provided preform;
an apparatus for stretching and blowing the preform such that the container for the infusion solution is moldable from the preform;
a second installation for cleaning the molded container;
a filling system in which the cleaned and optionally dried container by way of a filling opening which is present in the container may be filled at least with one infusion solution;
a third installation for closing the container,
an autoclave in which the closed container is sterilizable; and
a first conveying installation for guiding the preform in the heating installation and for infeeding the heated preform to the stretching and blowing apparatus in which the preform may be rotatably mounted and aligned by way of rotation, and a bending apparatus which is disposed ahead of the stretching and blowing apparatus and in which the preferably pre-aligned hanger of the preform may be turned over, wherein:
the first conveying installation has at least one movably disposed rotary pin on which the preform is mountable and by way of which rotation of the preform is providable, and/or
the bending apparatus is providable by an edge which is disposed ahead of the stretching and blowing apparatus, for example in or after the heating installation-and which in relation to the first conveying installation is disposed so as to be locationally fixed and laterally offset such that the hanger of the preform by means of the movement of the first conveying installation may be moved against the edge, be brought to bear and bent thereon.

12. The system as claimed in claim 11 , wherein the second installation is configured to dry the cleaned container.

13. The system as claimed in claim 11 , wherein the first installation is configured to provide the preform aligned such that a transverse axis (Q H ) of the hanger lies so as to be substantially transverse.

14. The system as claimed in claim 13 , wherein the first installation is configured to provide the preform aligned such that a transverse axis (Q H ) of the hanger lies perpendicularly to a movement direction (X) of the preform.

15. The system as claimed in claim 11 , wherein the first installation is configured to provide the preform such that the hanger of the preform is placed away from a longitudinal axis (L) of the preform in the direction of the base of the preform.

16. A system for producing a container filled with an infusion solution, the system comprising:
a first installation for providing a preform having a hanger disposed on a base of the preform, wherein:
the first installation is configured to provide the preform aligned such that a transverse axis (Q H ) of the hanger lies so as to be substantially transverse, and
the first installation is configured to provide the preform aligned such that a transverse axis (Q H ) of the hanger lies perpendicularly to a movement direction (X) of t
