Ball case, in particular for soccer balls

Abstract

In a ball case consisting of two-dimensional blanks which are connected with each other at their edges, with the surface of the ball case having a pattern of two different groups of polygons, it is suggested for reducing the number of the two-dimensional blanks and for reducing the overall seam length to combine a first group of polygons consisting of three-armed star-shaped areas with a second group of polygons integrally formed from partial areas of one equilateral triangle and of three equilateral pentagons in such a manner that the pentagonal areas are situated at the points of the corners of the triangle and an imaginary corner and/or the centre of each of the pentagons lies on the perpendicular bisector of the opposite side of the triangle.

       14 . A ball case consisting of two-dimensional blanks which are connected with each other at their edges, the surface of the ball case having a pattern of two different groups of polygons, of which a first group consists of three-armed star-shaped areas, and several three-armed star-shaped areas in planar development contiguously forming a one-piece two-dimensional blank, wherein a second group consists of polygons which are integrally formed from partial areas of one equilateral triangle and of three equilateral pentagons in such a manner that the pentagonal areas are situated at the points of the corners of the triangle and an imaginary corner and/or the centre of each of the pentagons lies on the perpendicular bisector of the opposite side of the triangle, said polygons being configured as separate, two-dimensional blanks. 
   
   
       15 . The ball case according to  claim 14 , consisting of 20 two-dimensional blanks, namely 4 identical polygons of the second group and 16 blanks in the form of three-armed star-shaped areas. 
   
   
       16 . The ball case according to  claim 14 , consisting of 8 two-dimensional blanks, namely 4 identical polygons of the second group and 4 identical one-piece blanks which each are composed of 4 three-armed star-shaped areas. 
   
   
       17 . The ball case according to  claim 14 , consisting of 6 two-dimensional blanks, namely 4 identical polygons of the second group and 2 identical one-piece blanks which each are composed of 8 three-armed star-shaped areas. 
   
   
       18 . The ball case according to  claim 14 , consisting of 5 two-dimensional blanks, namely 4 identical polygons of the second group and one single one-piece blank which is composed of 16 three-armed star-shaped areas. 
   
   
       19 . The ball case according to  claim 18 , wherein the one-piece blank has 6 terminal edges which are connected with each other in pairs. 
   
   
       20 . The ball case according to  claim 18 , wherein the one-piece blank has 6 terminal edges which are connected with each other in pairs and have a right-angled contour with its associated corners not being rounded. 
   
   
       21 . The ball case according to  claim 14 , wherein the corners of the equilateral pentagons and the corners, complementarily assigned thereto, of the three-armed star-shaped areas are rounded. 
   
   
       22 . The ball case according to  claim 14 , wherein all two-dimensional blanks are cut-outs punched out from a multi-layered composite material. 
   
   
       23 . The ball case according to  claim 14 , wherein all two-dimensional blanks are cut-outs punched out from a multi-layered composite material with said composite material comprising:
 a) a waterproof plastic coating layer defining the outer surface of the ball case,   b) a first foamed plastic layer,   c) a second foamed plastic layer and   d) a textile carrier layer impregnated with plastic material.   
   
   
       24 . The ball case according to  claim 23 , wherein the first foamed plastic layer comprises at least one of a thermoplastic polyolefin and a polyurethane. 
   
   
       25 . The ball case according to  claim 23 , wherein the second foamed plastic layer comprises at least one elastomer.
