Package Forming At Least One Pocket

Abstract

The package ( 10 ) forming at least one pocket delimited by at least one flexible film ( 12 ) having two principal faces ( 14, 16 ) which are connected to one another along at least two opposing transverse connecting lines ( 18, 20 ) which delimit the said pocket between them, characterised in that a first face ( 14 ) has a length measured between the two opposing connecting lines which is less than the length measured between the two opposing connecting lines of the second face ( 16 ), and in that the first face has a weakened line ( 40 ) between the two opposing connecting lines ( 18, 20 ).

1 . Package ( 10 ) forming at least one pocket delimited by at least one flexible film ( 12 ) having two principal faces ( 14 ,  16 ) which are connected to one another along at least two opposing transverse connecting lines ( 18 ,  20 ) which delimit the said pocket between them, characterised in that a first face ( 14 ) has a length measured between the two opposing connecting lines which is less than the length measured between the two opposing connecting lines of the second face ( 16 ), and in that the first face has a weakened line ( 40 ) between the two opposing connecting lines ( 18 ,  20 ). 
   
   
       2 . Package as claimed in  claim 1 , characterised in that the first and second faces ( 14 ,  16 ) are connected to one another laterally by longitudinal connecting lines ( 22 ,  24 ), and in that the second face ( 16 ) has an intermediate fold ( 30 ) extending between the transverse connecting lines ( 14 ,  16 ) from one longitudinal connecting line ( 22 ,  24 ) to the other. 
   
   
       3 . Package as claimed in  claim 2 , characterised in that the first and second faces ( 14 ,  16 ) are initially partially folded back on the first face ( 14 ) in order to form a flap ( 34 ) extending from a transverse connecting line ( 20 ) to the intermediate fold ( 30 ). 
   
   
       4 . Package as claimed in  claim 3 , characterised in that both the fold ( 30 ) and the flap ( 34 ) are formed by the first and second faces ( 14 ,  16 ) that are applied one on the other. 
   
   
       5 . Package as claimed in  claim 3 , characterised in that the weakened line ( 40 ) is provided on a region of the first face ( 14 ) covered by the said flap ( 34 ). 
   
   
       6 . Package as claimed in  claim 2 , characterised in that the weakened line ( 40 ) provided on the first face ( 14 ) and the intermediate fold ( 30 ) formed on the second face ( 16 ) are disposed substantially facing one another. 
   
   
       7 . Package as claimed in  claim 2 , characterised in that it is formed from one single film ( 12 ) which is folded back and welded on itself solely by welds ( 20 ,  22 ,  24 ) of the skin/skin type. 
   
   
       8 . Package as claimed in  claim 2 , characterised in that the flexible film ( 12 ) has, along the weakened line ( 40 ), at least one weakening mechanical treatment on at least one layer of the film. 
   
   
       9 . Package as claimed in  claim 8 , characterised in that the said weakening mechanical treatment comprises microporous weakening. 
   
   
       10 . Package as claimed in  claim 6 , characterised in that the weakening mechanical treatment comprises cutting or partial stamping of at least one layer of the film with the aid of a die with blades along the weakening line ( 40 ). 
   
   
       11 . Package as claimed in  claim 10 , characterised in that the film ( 12 ) has, along the weakened line ( 40 ), a weakening treatment by high-energy radiation along at least one layer of the film ( 12 ). 
   
   
       12 . Package as claimed in  claim 11 , characterised in that the film ( 12 ) comprises at least two layers, the first layer ( 52 ) having undergone a weakening treatment by high-energy radiation along the weakened line and the second layer having undergone a weakening mechanical treatment along the weakened line ( 40 ). 
   
   
       13 . Package as claimed in  claim 12 , characterised in that the first and second faces ( 14 ,  16 ) are connected to one another laterally by longitudinal connecting lines ( 22 ,  24 ) that extend on the entire length of said first and second faces ( 14 ,  16 ). 
   
   
       14 . Package as claimed in  claim 13 , characterised in that said longitudinal connecting lines ( 22 ,  24 ) are made by welding.
