Packaging container comprising an outer cardboard structure and an insert made of plastic film

Abstract

The invention relates to a packaging tray comprising an outer cardboard structure, inside which a plastic insert is provided. The invention further relates to a method for producing such a packaging tray and a packaging machine on which the packaging tray of said type and packaging to be produced thereby can be produced.

1 . A packaging tray comprising:
 an outer cardboard structure, in which an insert made of plastic film is provided,   wherein a gas cushion is provided between the cardboard structure and the insert, at least over portions,   wherein the cardboard structure and the insert are bonded integrally to one another in the upper edge region of the side wall, and   wherein the integral bond is only provided locally and not over the entire periphery.   
     
     
         2 - 18 . (canceled) 
     
     
         19 . The packaging tray of  claim 1 , wherein the contour of the insert does not follow the contour of the cardboard, at least in portions,
 wherein the insert has a side wall, and in that a step is provided in this side wall.   
     
     
         20 . The packaging tray of  claim 1 , wherein the wall thickness of the insert in the base region is smaller than in the region of the side wall. 
     
     
         21 . The packaging tray of  claims 1 , wherein the packaging tray has a storage space, at least in portions, between the cardboard structure and the insert, in particular in the base region of the packaging tray. 
     
     
         22 . The packaging tray of  claim 21 , wherein a means for opening the cardboard structure is provided in the cardboard structure in the region of the storage space, in the base region, so as to obtain access to the storage space. 
     
     
         23 . The packaging tray  claim 22 , wherein an aid and/or a meal component is arranged in the storage space. 
     
     
         24 . A method for producing a packaging tray comprising:
 an outer folded cardboard structure, in which an insert made of plastic film is provided,   wherein the insert is completely thermoformed before it is introduced into the folded cardboard structure.   
     
     
         25 . The method as claimed in  claim 24 , wherein the cardboard structure is fitted onto the insert from beneath. 
     
     
         26 . The method as claimed in  claim 24 , wherein the cardboard structure is bonded integrally to the insert. 
     
     
         27 . A method for producing a packaging tray comprising:
 an outer folded cardboard structure, in which an insert made of plastic film is provided,   wherein the insert is thermoformed at least in part while the insert is introduced into the folded cardboard structure,   wherein the folded cardboard structure is fitted from beneath onto the insert, which is still unformed, and said insert is formed subsequently and/or simultaneously.   
     
     
         28 . The method as claimed in  claim 27 , the cardboard structure is bonded integrally to the insert. 
     
     
         29 . The method of  claim 27 , wherein the packaging tray is produced in a packaging machine comprising:
 1. a thermoforming station,   2. a filling station and   3. a sealing station,   4. a connecting station between the sealing station and the thermoforming station and connects a thermoformed insert to a folded cardboard structure.   
     
     
         30 . The method of  claim 29 , wherein a connecting station is integrated into the thermoforming station and connects a thermoformed insert to a cardboard structure. 
     
     
         31 . The method of  claim 29 , wherein before the insert is connected to the cardboard structure, the insert is transported in a first direction in the packaging machine, and in that said packaging machine transports the cardboard structure along two second directions, which each run perpendicular to the first transport direction. 
     
     
         32 . The method of  claim 29 , wherein handling devices and/or robots are provided for the transport of the cardboard. 
     
     
         33 . The method of  claim 24 , wherein the packaging tray is produced in a packaging machine comprising:
 a) a thermoforming station;   b) a filling station;   c) a sealing station; and   d) a connecting station between the sealing station and the thermoforming station and connects a thermoformed insert to a folded cardboard structure.   
     
     
         34 . The method of  claim 33 , wherein a connecting station is integrated into the thermoforming station and connects a thermoformed insert to a cardboard structure. 
     
     
         35 . The method of  claim 33 , wherein before the insert is connected to the cardboard structure, the insert is transported in a first direction in the packaging machine, and in that said packaging machine transports the cardboard structure along two second directions, which each run perpendicular to the first transport direction. 
     
     
         36 . The method of  claim 33 , wherein handling devices and/or robots art provided for the transport of the cardboard. 
     
     
         37 . The method of claim  38 , wherein the packaging tray comprises:
 an outer cardboard structure, in which an insert made of plastic film is provided,   wherein a gas cushion is provided between the cardboard structure and the insert, at least over portions,   wherein the cardboard structure and the insert are bonded integrally to one another in the upper edge region of the side wall, and   wherein the integral bond is only provided locally and not over the entire periphery.
