Blank and three-dimensional structure produced therefrom

Abstract

The present invention relates to a blank ( 10 ) for producing a three-dimensional structure of paper, cardboard or plastic, in particular. The invention further relates to a three-dimensional structure produced from the blank, a folding box for storing goods, in particular a folding box made from cardboard, paper or the like as well as to a method for producing the blank ( 10 ).

1 . A blank for producing a three-dimensional structure of paper, cardboard or plastic, in particular a packing or the like, including at least one folding surface for forming a rounded edge area of the three-dimensional structure in a folded state of the blank,
 wherein the folding surface is bounded by two lateral folding lines extending parallel to each other, and   wherein at least one creasing line extending at an angle to the lateral folding lines is formed within the folding surface.   
     
     
         2 . The blank according to  claim 1 , wherein the lateral folding lines and the creasing line are produced by means of laser energy and/or punching. 
     
     
         3 . The blank according to  claim 1 , wherein the creasing line extends between a first end and/or corner area of the folding surface and a second end and/or corner area of the folding surface opposing the first end and/or corner area. 
     
     
         4 . The blank according to  claim 1 , wherein the creasing line is formed within the folding surface outside of a first end and/or corner area of the folding surface and outside of a second end and/or corner area of the folding surface opposing the first end and/or corner area. 
     
     
         5 . The blank according to  claim 1 , wherein at least one end of the creasing line intersects or adjoins to a corresponding lateral folding line of the folding surface. 
     
     
         6 . The blank according to  claim 1 , wherein the folding surface is divided into at least two partial areas by means of the at least one creasing line, wherein the partial areas are each triangularly formed. 
     
     
         7 . The blank according to  claim 6 , wherein further creasing lines are formed in at least one partial area. 
     
     
         8 . The blank according to  claim 1 , wherein the creasing line is formed straight, bent, wave-like, meandering, step-like or combinations thereof. 
     
     
         9 . The blank according to  claim 1 , wherein any one of the creasing line is formed as a creasing line continuous or discontinuous between the lateral folding lines. 
     
     
         10 . A three-dimensional structure of paper, cardboard or plastic, which is produced by folding and/or adhering a blank according to  claim 1 . 
     
     
         11 . The three-dimensional structure according to  claim 10 , wherein the three-dimensional structure is a packing, in particular a packing for storing cigarettes. 
     
     
         12 . A folding box for storing goods, in particular a folding box of cardboard, paper or the like, including
 at least one front wall, at least one rear wall and at least a first sidewall and a second sidewall for connecting the front wall and the rear wall,   a bottom construction for bottom-side closure of the folding box, and   multiple folding surfaces for forming each one rounded edge area of the folding box, wherein at least one folding surface is bounded by lateral folding lines and at least one creasing line extending at an angle to the lateral folding lines is formed within the folding surface.   
     
     
         13 . The folding box according to  claim 12 , wherein at least one end of the creasing line intersects or adjoins to a corresponding lateral folding line of the folding surface. 
     
     
         14 . The folding box according to  claim 12 , wherein the creasing line is formed as a creasing line continuous or discontinuous between the lateral folding lines. 
     
     
         15 . A method for producing a blank according to  claim 1 , wherein an outer contour of the blank and/or the folding lines and/or cutting lines and/or an inner contour of the blank and/or creasing lines are produced by means of laser energy. 
     
     
         16 . The blank according to  claim 1 , wherein the at least one creasing line extends between a first end and/or corner area of the folding surface and an area, which is spaced from a second end and/or corner area opposing the first end and/or corner area.
