Method for packaging roll of paper and the packaging box to be applied therewith

Abstract

A method for packaging a roll of paper using a sheet of packaging material, whereby in the sheet of packaging material are applied a number of creases or folding lines running parallel to one another and bordering neighboring sheet parts. The sheet of packaging material is folded around the creases or folding lines in order to form a polygonal packaging box for the paper roll. The packaging box is formed by the sheet parts enclosing an angle with one another. Partitions are fitted inside the packaging box near the ends of the packaging box. A packaging box made by the method and sheets of packaging material to be used for making the packaging box and the enclosing member are also described.

1 . A method for packaging a roll of paper using a sheet of packaging material, said method comprising the steps of:
 applying a number of creases or folding lines in the sheet of packaging material to form a plurality of sheet parts, said number of creases or folding lines running parallel to one another and bordering neighboring sheet parts of the plurality of sheet parts;   folding the sheet of packaging material around the creases or folding lines in order to form a polygonal packaging box for the paper roll, the packaging box being formed by the plurality of sheet parts enclosing an angle with one another;   tightly fitting the packaging box around the roll of paper by fitting the sheet of packaging material directly tightly around the roll while folding around the creases or folding lines;   measuring the sheet of packaging material such that the packaging box thus formed around the roll of paper protrudes beyond opposite ends of the roll of paper;   forming a pair of one-piece enclosing members from a sheet of packaging material, each of said one-piece enclosing members being constructed from a partition and edge parts forming a unit with the partition, the edge parts being bent around the partition and enclosing an angle with one another, the dimension of the one-piece enclosing members being generally the same as an internal polygonal cross-section of the packaging box formed around the roll of paper;   fitting the one-piece enclosing members inside opposite ends of the packaging box, so that the partitions touch opposite ends of the roll of paper and the edge parts touch inner sides of the plurality of sheet parts of the packaging box when the roll of paper is fitted inside of the packaging box.   
   
   
       2 . The method according to  claim 1 , further comprising the step of gluing the edge parts of the enclosing members to the inner sides of the plurality of sheet parts of the packaging box. 
   
   
       3 . The method according to  claim 1 , wherein the packaging box is given a hexagonal cross-section while folding the packaging material around the roll of paper. 
   
   
       4 . The method according to  claim 1 , wherein the sheet of packaging material is cardboard. 
   
   
       5 . The method according to  claim 1 , wherein the packaging box is formed such that the ends of the packaging box protrude by between 0.5-5 cm beyond the ends of the roll of paper surrounded by the packaging box. 
   
   
       6 . A packaging box created using the method according to  claim 1 . 
   
   
       7 . A sheet of packaging material used for creating a packaging box according to  claim 6 . 
   
   
       8 . A sheet of packaging material used for creating an enclosing member to be applied in the method according to  claim 1 .
