Abstract

A machine for producing and filling containers, having: a heating device for thermal conditioning thermoplastic parisons; a blow-molding device for deforming the thermally conditioned parisons into containers by blow-molding or stretch blow-molding; a device for filling the containers with a product; and a transfer device for conveying the containers from the blow-molding device to the filling device. A nozzle arrangement is arranged in the region of the transfer device for impinging a cooling liquid on the containers. The nozzle arrangement has a gas nozzle connected by a gas line to a gas source. The nozzle arrangement has a liquid nozzle connected by a liquid line to a liquid source. The gas nozzle and the liquid nozzle are arranged and oriented relative to one another such that a liquid jet from the liquid nozzle strikes a gas jet from the gas nozzle in an intersection region.

First claim

I claim:

1. A machine for producing and filling containers, comprising: at least one heating device for thermal conditioning of parisons composed of a thermoplastic material; at least one blow-molding device for deformation of the thermally conditioned parisons to form in each case one container by way of a blow-molding process or a stretch blow-molding process; at least one filling device for filling the containers with a product; a transfer device for conveying the containers from the blow-molding device to the filling device; and at least one nozzle arrangement in a region of the transfer device for impinging a cooling liquid on the containers, wherein the nozzle arrangement includes a gas nozzle connected by a gas line to a gas source, and a liquid nozzle connected by a liquid line to a liquid source, wherein the gas nozzle and the liquid nozzle are arranged and oriented relative to one another so that a liquid jet from the liquid nozzle strikes a gas jet from the gas nozzle in an intersection region, wherein the nozzle arrangement is mounted so as to be rotatable and/or pivotable.

2. The machine according to claim 1 , wherein the gas nozzle and the liquid nozzle are arranged transversely with respect to one another.

3. The machine according to claim 2 , wherein the gas nozzle and the liquid nozzle are arranged and oriented so that the gas jet and the liquid jet strike one another in the intersection region at a predefinable angle of 80 to 100 degrees.

4. The machine according to claim 3 , wherein the predefinable angle is 85 to 95 degrees.

5. The machine according to claim 4 , wherein the predefinable angle is 87 to 93 degrees.

6. The machine according to claim 1 , wherein the nozzle arrangement is arranged below a conveying path for the containers in the transfer device, wherein the containers are conveyed in suspended fashion in the transfer device.

7. The machine according to claim 6 , wherein the containers are suspended with a base pointing downward.

8. The machine according to claim 6 , wherein the gas nozzle is arranged and oriented for a substantially vertically upwardly directed gas jet, and wherein the liquid nozzle is arranged and oriented for a substantially horizontally directed liquid jet.

9. The machine according to claim 1 , wherein the nozzle arrangement is rotatable and/or pivotable in a plane oriented transversely with respect to a conveying direction of the containers.

10. The machine according to claim 1 , comprising a plurality of nozzle arrangements, which are connected to a common gas source and/or a common liquid source.

11. The machine according to claim 1 , wherein the nozzle arrangement includes a central body that holds the gas nozzle and the liquid nozzle.

12. The machine according to claim 11 , wherein the central body comprises an internal gas duct for connecting the gas nozzle to a port for the gas line and/or an internal liquid duct for connecting the liquid nozzle to a port for the liquid line.

13. The machine according to claim 11 , wherein the gas nozzle and/or the liquid nozzle are/is detachably connected to the central body.

14. The machine according to claim 13 , wherein the gas nozzle and/or the liquid nozzle are/is screwed to the central body in a gas-tight and/or liquid-tight manner.

15. The machine according to claim 11 , wherein the central body is substantially L-shaped.
