Flexible package for liquid products

Abstract

A package ( 1, 1′ ) in flexible material for liquid, pasty products or the like, closed above by a linear head weld ( 7 ) which joins two opposed walls ( 4, 5 ), at which a pair of opposed welds ( 10, 11 ) is provided, in proximity of at least one upper corner ( 8 ) of the package, these opposed welds ( 10, 11 ) tending to meet at the centre line of the package and determining a flattening of the corresponding upper corner ( 8 ).

1 . A package ( 1 ,  1 ′) made of a flexible material for liquid, pasty products and the like, closed upside by means of a linear head weld ( 7 ) connecting two opposed side walls ( 4 ,  5 ) of the package, thereby determining respective upper corners ( 8 ) at its ends, characterized in that it provides near at least one of said upper corners ( 8 ), on the two opposed walls ( 4 ,  5 ) of the package, respective welds ( 10 ,  11 ) which tend to joint at the package center line, forming a V with the vertex near said upper corner ( 8 ). 
     
     
         2 . A package ( 1 ,  1 ′) according to  claim 1 , wherein said pair of opposed welds ( 10 ,  11 ) determine a flattening of the correspondent upper corner ( 8 ) of the package. 
     
     
         3 . A package ( 1 ,  1 ′) according to  claim 1 , characterized in that said linear head weld ( 7 ) is provided near the level of the liquid held within the package. 
     
     
         4 . A package ( 1 ,  1 ′) according to  claim 1 , wherein a pair of opposed welds ( 10 ,  11 ) are provided at each of said upper corners ( 8 ) of the package. 
     
     
         5 . A package ( 1 ,  1 ′) according to  claim 1 , wherein the deliver of the product is carried out by making a cut at one of said upper corners ( 8 ) to determine an aperture ( 12 ) delimited by said pair of opposed welds ( 10 ,  11 ). 
     
     
         6 . A package ( 1 ,  1 ′) according to  claim 5 , wherein said cut also involve said pair of opposed welds ( 10 ,  11 ). 
     
     
         7 . A package ( 1 ) according to  claim 1 , which is of the stand-up type. 
     
     
         8 . A package ( 1 ′) according to  claim 1 , which is parallelepiped in shape. 
     
     
         9 . A package ( 1 ,  1 ′) according to  claim 2 , characterized in that said linear head weld ( 7 ) is provided near the level of the liquid held within the package.
