Elastic double bag

Abstract

The invention relates to a bag ( 1 ) in the form of a double bag, consisting of at least two layers (E 1 et E 2 ) of material. Said layers are the same shape and have the same dimensions, are superposed and interconnected along the periphery ( 2 - 5 ) thereof in such a way that they define two pockets (P 1 et P 2 ) which are accessible by an opening ( 7 ) made in the longitudinal direction of the bag ( 1 ). Furthermore, the material forming at least one of the layers (E 1 et E 2 ) is extensible in the machine direction and/or in the cross-machine direction.

1 - 10 . (canceled)  
   
   
       11 . A scrip-type bag, consisting of at least two layers of material, of the same shape and same dimensions, that are superposed and secured to one another along their periphery so as together to define two pockets that can be accessed via a central opening, said bag having a longitudinal direction and a transverse direction, characterized in that said opening is made in the longitudinal direction of the bag and in that said material forming at least one of the layers is a fabric that can stretch in the machine direction and/or in the cross direction.  
   
   
       12 . The bag as claimed in  claim 11 , characterized in that said opening is made in said periphery.  
   
   
       13 . The bag as claimed in  claim 11 , characterized in that the extension of said stretch fabric is different in the machine direction and in the cross direction, and in that, in the bag, the direction of greater extension is used transversely.  
   
   
       14 . The bag as claimed in  claim 11 , characterized in that said fabric has a weight per m 2  of between approximately 60 and 400 g/m 2 .  
   
   
       15 . The bag as claimed in  claim 11 , characterized in that at least one strip of inelastic material is provided along the periphery of said layers.  
   
   
       16 . The bag as claimed in  claim 11 , characterized in that at least one strip of inelastic material, which does not affect the transverse zone of the bag containing said opening, is provided along the periphery of said layers.  
   
   
       17 . The bag as claimed in  claim 11 , characterized in that it consists of a single piece of fabric folded over on itself so as to form two superposed thicknesses of fabric, said two thicknesses being sewn right along their free edges, an opening nevertheless being provided in the middle of the side opposite the side forming the fold line.  
   
   
       18 . The bag as claimed in  claim 11 , characterized in that it has a rectangular shape and, when empty, a length of between approximately 70 and approximately 100 cm and a width of between approximately 40 and approximately 60 cm.  
   
   
       19 . The bag as claimed in  claim 11 , characterized in that, when empty, said opening has a length between approximately 10 and approximately 20 cm.  
   
   
       20 . The bag as claimed in  claim 11 , characterized in that a visual or tactile reference means is associated with said opening.
