Bag for foodstuff and, in particular, bag for foodstuffs of the granule type

Abstract

The invention relates to a bag for foodstuffs including a base, and also two principal walls and two lateral flanks extending from said base, these walls and flanks being made from a material of flexible-sheet type, the two walls being, at their end opposite the base, assembled together along an assembling line, the two flanks, at their end opposite the base, being shaped as a gusset. The bag also includes an opening line which extends, in the region shaped as a gusset, of one lateral flank, in the vicinity of one end of the region opposite the base, said region forming a gusset being capable of adopting two positions when the opening line is open. One position corresponds to its position when the bag is closed, the other being one in which the gusset shape is turned out and defines a pouring spout capable of guiding the foodstuffs as far as the opening.

What is claimed is:  
     
         1 . Bag for foodstuffs including a base ( 1 ), and also two principal walls ( 2 ) and two lateral flanks ( 3 ) extending from said base ( 1 ), these walls ( 2 ) and flanks being made from a material of flexible-sheet type, the two walls ( 2 ) being, at their end opposite the base ( 1 ), assembled together along an assembling line ( 4 ), the two flanks, at their end opposite the base ( 1 ), being shaped as a gusset ( 8 ), said bag also including an opening line ( 5 ,  9 ), characterized in that said opening line ( 5 ,  9 ) extends, in the region shaped as a gusset, of one lateral flank, in the vicinity of one end of said region opposite said base ( 1 ), said region forming a gusset ( 8 ) being capable of adopting two positions when the opening line ( 5 ,  9 ) is open, one which corresponds to its position when the bag is closed, the other being one in which the gusset shape is turned out and defines a pouring spout ( 6 ) capable of guiding the foodstuffs as far as the opening ( 5 ).  
     
     
         2 . Bag according to  claim 1 , characterized in that the opening line ( 5 ,  9 ) extends over an entire width of said lateral flank ( 3 ).  
     
     
         3 . Bag according to one of the preceding claims, characterized in that the opening line ( 5 ,  9 ) is arranged below the assembling line ( 4 ) of the two principal walls ( 2 ), in the immediate vicinity of said line.  
     
     
         4 . Bag according to one of the preceding claims, characterized in that the gusset also has closure means of the removable anchoring type.  
     
     
         5 . Bag for foodstuffs according to one of the preceding claims, characterized in that it is intended for containing granule-type foodstuffs.
