Packaging made of cellulose material and opening method

Abstract

Disclosed is a packaging for piece goods having a folded shell made of cellulose-containing flat material. The shell and a cover enclose an interior of the packaging. The shell has a first side wall, on which a first sealing rim is angled outwardly away from the interior along a first fold edge. The cover is glued to the first sealing rim. The packaging has a perforation for tearing off the first sealing rim together with the portion of the cover glued to it from the first side wall on the first fold edge. Also disclosed is a method for opening a packaging which also has a second side wall, on which a second sealing rim is angled outwardly away from the interior along a second fold edge, with the cover being glued to the first sealing rim and to the second sealing rim.

1 . A packaging, comprising:
 a folded shell made of cellulose-containing flat material and a cover;   wherein the shell and the cover enclose an interior of the packaging;   wherein the shell has a first side wall on which a first sealing rim is angled outwardly away from the interior along a first fold edge;   wherein the cover is glued to the first sealing rim;   wherein a perforation configured for the joint tearing of the first sealing rim and a portion of the cover glued to it from the first side wall is formed on the first fold edge;   wherein the shell has a second side wall on which a second sealing rim is angled outwardly away from the interior along a second fold edge; and   wherein the cover is glued to the second sealing rim in such a way that a strength of the bonding of the cover to the second sealing rim is greater than a strength of the material of the cover and/or the shell.   
     
     
         2 . The packaging according to  claim 1 , wherein the perforation is formed with perforation openings which completely penetrate the flat material of the shell. 
     
     
         3 . The packaging according to  claim 1 , wherein the perforation is formed with indentations in the flat material of the shell, wherein a remaining thickness of the flat material at the indentations is further reduced as compared to the first fold edge. 
     
     
         4 . The packaging according to  claim 1 , wherein the perforation on the first fold edge extends over the entire length of the first fold edge. 
     
     
         5 . The packaging according to  claim 1 , wherein a base element of the cover consists of cellulose-containing flat material. 
     
     
         6 . The packaging according to  claim 1 , wherein a further perforation is formed on the second fold edge for tearing off the second sealing rim together with a portion of the cover glued to it from the second side wall. 
     
     
         7 . The packaging according to  claim 1 , wherein the cover and/or the shell have at least one viewing window which is closed by a transparent closure element. 
     
     
         8 . The packaging according to  claim 1 , wherein a hanging recess breaks through the first sealing rim and the portion of the cover glued to it. 
     
     
         9 . The packaging according to  claim 1 , wherein an insert for fixing an object which can be received in the packaging is arranged in the shell. 
     
     
         10 . A bundle comprising the packaging according to  claim 1  and an object which is received in the packaging. 
     
     
         11 . A method for opening a packaging, the method comprising the steps of:
 a) providing the packaging which has a shell folded from cellulose-containing flat material and a cover, wherein the shell and the cover enclose an interior of the packaging, wherein the shell has a first side wall on which a first sealing rim is angled outwardly away from the interior along a first fold edge, wherein the shell has a second side wall on which a second sealing rim is angled outwardly away from the interior along a second fold edge, and wherein the cover is glued to the first sealing rim and to the second sealing rim, wherein a perforation is formed on the first fold edge;   b) joint tearing the first sealing rim with a portion of the cover glued to it from the first side wall along the perforation on the first fold edge; and   c) pulling off the cover from the second sealing rim.   
     
     
         12 . The method according to  claim 11 , wherein the shell and/or the cover contain fibers, in particular cellulose fibers, which are torn in step c). 
     
     
         13 . A method for providing an object, comprising the steps of:
 A) providing a blank made of cellulose-containing flat material and a cover;   B) creating a first fold edge with a perforation in the blank, wherein the first fold edge delimits a first side wall from a first sealing rim, and a second fold edge in the blank, wherein the second fold edge delimits a second side wall from a second sealing rim;   C) folding a shell from the blank;   D) inserting the object into the shell;   E) gluing the cover to the first and the second sealing rim of the shell;   F) opening the packaging by, in a step a), tearing off the first sealing rim together with the portion of the cover glued to it along the perforation on the first fold edge from the first side wall and, in a step b), pulling off the cover from the second sealing rim.
