Embodiment Construction

[0014] The device shown in Figure 1 for the manufacture of filled and closed containers, such as ampoules for filling pharmaceutical preparations, has a first part generally indicated by 10, which has an extruder 12, wherein in this embodiment Two extruders 12 are used in the example. The extruders 12 can be of different sizes; in this case, however, the two extruders 12 are substantially the same size, ie they supply the same volume flow of the plastic material to be added to the common extrusion head 14 . The actual top surfaces of the extruder 12 and the extrusion head 14 therefore lie at a common input level. The above-mentioned extrusion head or extrusion head 14 has an outlet for the plastic hose on its bottom surface, and the extrusion head 14 can co-extrude two layers that together form the hose, said layers are passed through the extruder 12 supply.

[0015] The extrusion head 14 , not shown and described in detail, enables so-called nozzle co-extrusion, in which th...

Abstract

Method and device for producing at least one plastic container filled with a medium, wherein the plastic material is extruded into a tube and pressed against the inner wall of a forming mold by means of a pressure difference in order to form a corresponding container, a corresponding container The filling opening of the container is filled with a medium by means of a filling device and the filling opening of the container is closed by a seal, wherein a co-extrusion method is used for extruding different plastic materials, wherein the corresponding container is at least partially made of A plurality of layers of plastic material is formed, and at least one of said layers acts as a barrier layer.

Description

technical field [0001] The invention relates to a method for producing at least one plastic container filled with a medium, wherein: [0002] -The plastic material is extruded into a tube shape, and the plastic material is pressed against the inner wall of a forming mold by means of a pressure difference to form a corresponding container, [0003] - the respective container is filled with a medium via its filling opening by means of a filling device, [0004] - closing the filling mouth of the container by means of a seal, [0005] The invention also relates to a device for carrying out the above-mentioned method. Background technique [0006] A method of this type for producing a liquid-filled thermoplastic container is known from DE 38 32 566 C2, as well as a device with an extrusion head for carrying out the method. In a known method, plastic is extruded into wide flat tubes, wherein the shaping of the flat tubes in the shape of a container strip into containers, in pa...
