Abstract

The present invention is directed to a cap for laminated carton packaging for beverages, wherein the laminated carton packaging for beverages comprise a cap made of plastic and a packaging body, tools for deep drawing of such a cap, method of manufacturing such a cap as well as the laminated carton packaging for beverages provided therewith. In order to create a constructively simple to assemble and therefore cost-effective cap which can be manufactured and to make available the respective tools as well as the method for their manufacture, it is provided that the cap has a spout element provided with a screw thread which is closed by a screw cap and that the cap is deep drawn. For this purpose various tools and manufacturing methods are described.

Claims (51)

1 - 24 . (canceled)

25 . A cap for a laminated carton packaging for beverages, wherein the cap:

is constructed of plastic;

includes a spout element having a screw thread and a spout opening designed to be closed by a screw cap; and

is deep drawn, further wherein the laminated carton packaging includes a packaging body.

26 . The cap according to claim 25 , wherein the spout element has a screw thread with at least one thread turn.

27 . The cap according to claim 25 , wherein the spout element has a screw thread with at least one thread turn and the at least one thread turn comprises several thread sections arranged with a distance to each other and aligned with each other.

28 . The cap according to claim 25 , wherein the plastic is a deep drawing monomer foil.

29 . The cap according to claim 25 , wherein the plastic is a deep drawing multilayer foil.

30 . The cap according to claim 29 , wherein the multilayer foil has at least one of oxygen and aroma barrier properties.

31 . The cap according to claim 25 , wherein the cap has a circumferential upward angled edge.

32 . The cap according to claim 25 , wherein the cap has a circumferential downward angled edge.

33 . The cap according to claim 25 , wherein the cap has a circumferential upward angled edge with a concentric adjacent collar with a slightly outward pitch and downward tapering periphery.

34 . The cap according to claim 25 , wherein the spout opening is sealed by a film before an unscrewing of the screw cap.

35 . The cap according to claim 25 , wherein the screw cap is screwed liquid-tight onto the spout element.

36 . A tool for deep drawing a cap for a laminated carton packaging for beverages having a deep drawing form with a multitude of suction holes, comprising:

the deep drawing form including a thread feed pipe, wherein,

before a deep drawing procedure, the thread feed pipe is moved out of a tool body of the deep drawing form into a working position via a spindle drive; and

after the deep drawing procedure, the thread feed pipe is unscrewed out of the cap, further wherein the cap is formed of rigid plastic.

37 . A tool for deep drawing a cap for laminated carton packaging for beverages with a deep drawing form having a multitude of suction holes, comprising:

the deep drawing form including a tube arranged with recesses formed as screw threads;

a spreading tool, positioned under the tube, arranged with a multitude of elevations executed as a thread turn corresponding to divisions of the spreading tool, wherein,

the spreading tool is driven into the tube during a deep drawing procedure thereby moving the elevations of the spreading tool outwardly through the recesses of the tube.

38 . The tool according to claim 37 , wherein the tube and the spreading tool have a slightly conical form.

39 . The tool according to claim 37 , wherein the spreading tool comprises three spreading elements.

40 . The tool according to claim 36 , wherein knives are arranged in the tool of the deep-drawing form for punching out at least one of the cap and the spout opening of the cap.

41 . A method for manufacturing a cap for a laminated carton packaging for beverages, wherein the laminated carton packaging for beverages comprises a plastic cap and a packaging body, comprising the steps of:

supplying a plasticized foil over a deep drawing form having a thread feed pipe projecting out of a tool body;

deep drawing of the foil;

releasing of a deep drawn cap after an unscrewing of the thread feed pipe from the cap by means of screwing into the tool body; and

punching out the cap and a spout opening.

42 . A method of manufacturing a cap for a laminated carton packaging for beverages, wherein the laminated carton packaging for beverages comprises a cap constructed from plastic and a packaging body, comprising the steps of:

supplying a plasticized foil over a deep drawing form having a tube and a spreading tool, wherein the spreading tool includes thread turns;

spreading out the spreading tool;

deep drawing the foil over the thread turns of the spreading tool, wherein the spreading tool is in a spread-out position;

releasing a deep drawn cap after coincided driving of the thread turns forming the spreading tool; and

punching out the cap and a spout opening.

43 . The method according to claim 42 , wherein the supplying of the plasticized foil over the deep drawing form and the spreading out of the spreading tools in an inside of the tube occur simultaneously.

44 . The method according to claim 42 , wherein the releasing of the deep drawn cap and the punching out of the cap and the spout opening occur simultaneously.

45 . The method according to claim 41 , wherein the releasing of the deep drawn cap and the punching out of the cap and the spout opening occur simultaneously.

46 . A laminated carton packaging for beverages, comprising:

a cap; and

a packaging body,

wherein the cap:

is constructed of plastic;

includes a spout element having a screw thread and a spout opening designed to be closed by a screw cap; and

is deep drawn.

47 . The laminated carton packaging for beverages with a cap according to claim 46 , wherein the packaging body comprises carton/plastic/Al laminate material.

48 . The laminated carton packaging for beverages with a cap according to claim 46 , wherein the packaging body comprises a jacket constructed of carton/plastic laminate material and a bottom constructed of plastic.

49 . The laminated carton packaging for beverages with a cap according to claim 46 , wherein the packaging body comprises a jacket constructed of carton/plastic/Al laminated material and a bottom constructed of plastic.

50 . The laminated carton packaging for beverages with a cap according to claim 46 , wherein the packaging body comprises carton/plastic laminate material.
