Packaging Unit for Pipe Sections

Abstract

The present invention concerns a packaging unit ( 1 ) for several pipe sections ( 2 ) of mineral wool with a packaging material ( 5 ), which surrounds the several pipe sections ( 2 ) to form the packaging unit ( 1 ), with the packaging material ( 5 ) arranged around the pipe sections ( 2 ) under pressure, the pipe sections ( 2 ) are folded within the packaging unit ( 1 ) with reduction of the pipe section cavity, and the pipe sections ( 2 ) are formed elastically such that, in the folded state, recovery forces for restoring the unfolded initial shape are built up. By means of the packaging unit ( 1 ) of the invention, several pipe sections ( 2 ) can be transported and stored very economically. In this connection, pipe sections ( 2 ) are not restricted in their functionality, but, after removal from packaging unit ( 1 ), may be used directly and without restriction, e.g., to insulate chimneys.

1 . Packaging unit ( 1 ) for several pipe sections ( 2 ) of mineral wool with a packaging material that at least partially envelops or surrounds several pipe sections ( 2 ) to form packaging unit ( 1 ), characterised by the fact that the packaging material is arranged around pipe sections ( 2 ) under pressure, pipe sections ( 2 ), as a result of the pressure, are folded within packaging unit ( 1 ) with reduction of the pipe section cavity, and pipe sections ( 2 ) are formed elastically such that, in the folded state, recovery forces for restoring the unfolded initial shape are built up. 
   
   
       2 . Packaging unit ( 1 ) as defined by  claim 1 , characterised by the fact that both ends of packaging unit ( 1 ) are surrounded in a container-like manner, i.e. on five sides, by a cardboard box ( 3 ,  4 ), such that packaging unit ( 1 ) is held in a quadratic structure. 
   
   
       3 . Packaging unit ( 1 ) as defined by  claim 1 , characterised by the fact that packaging unit ( 1 ) is held by at least one banderol as packaging material. 
   
   
       4 . Packaging unit ( 1 ) as defined by  claim 3 , characterised by the fact that two banderols are arranged close to the end faces of packaging unit ( 1 ), and preferably a third is in the middle. 
   
   
       5 . Packaging unit ( 1 ) as defined by  claim 1 , characterised by the fact that the packaging material has a packaging film ( 5 ) of plastic, especially one that is waterproof. 
   
   
       6 . Packaging unit ( 1 ) as defined by  claim 5 , characterised by the fact that packaging film ( 5 ) is attached by film bonding. 
   
   
       7 . Packaging unit ( 1 ) as defined by  claim 5 , characterised by the fact that packaging film ( 5 ) is formed as shrink-wrap film. 
   
   
       8 . Packaging unit ( 1 ) as defined by  claim 1 , characterised by the fact that, for transporting packaging unit ( 1 ), provision is made for a handle that is formed especially from a film strip joined to the packaging material. 
   
   
       9 . Packaging unit ( 1 ) as defined by  claim 1 , characterised by the fact that provision is made for at least one piece of cardboard ( 3 ,  4 ), which is at least the size of one side-face of packaging unit ( 1 ) and preferably is surrounded by the packaging material. 
   
   
       10 . Packaging unit ( 1 ) as defined by  claim 1 , characterised by the fact that pipe sections ( 2 ) in the unfolded state have a circular, oval or rectangular cross-sectional shape. 
   
   
       11 . Packaging unit ( 1 ) as defined by  claim 1 , characterised by the fact that pipe sections ( 2 ) are folded relative to a principal dimension. 
   
   
       12 . Packaging unit ( 1 ) as defined by  claim 11 , characterised by the fact that the principal dimension is the diameter of the pipe sections ( 2 ), and the pipe sections ( 2 ) assume an elliptical cross-section in the folded state. 
   
   
       13 . Packaging unit ( 1 ) as defined by  claim 1 , characterised by the fact that pipe sections ( 2 ) in packaging unit ( 1 ) are folded only to the extent that the mineral wool itself remains largely free of compression. 
   
   
       14 . Packaging unit ( 1 ) as defined by  claim 1 , characterised by the fact that pipe sections ( 2 ), relative to the direction of folding, are arranged behind each other in a line. 
   
   
       15 . Packaging unit ( 1 ) as defined by  claim 2 , characterised by the fact that it comprises three, four or five pipe sections ( 2 ). 
   
   
       16 . Packaging unit ( 1 ) as defined by  claim 1 , characterised by the fact that pipe sections ( 2 ) especially are laminated with aluminium film. 
   
   
       17 . Packaging unit ( 1 ) as defined by  claim 1 , characterised by the fact that at least one folded pipe section ( 2 ) is accommodated or inserted in the cavity of an unfolded pipe section ( 2 ).
