Package comprising at least two opposite walls as well as a method for manufacturing such a package

Abstract

The invention relates to a package ( 1 ) comprising at least two opposite walls ( 3, 5 ) which are bonded together along a longitudinally extending bonding seam ( 16, 17 ). Each wall ( 3, 5 ) comprises at least two bonded-together wall members ( 6, 7; 8, 9 ), which are folded onto each other about a fold line ( 10, 11 ), wherein parts ( 26, 27 ) of the walls ( 3, 5 ) positioned on either side of the wall members ( 6, 7; 8, 9 ) can be moved away from each other in directions (P 1 , P 2 ) extending parallel to the longitudinal direction of the bonding seam ( 16, 17 ), wherein the opposite wall members ( 6, 7; 8, 9 ) can be moved apart, bounding an opening that gives access to a space present inside the package ( 1 ).

1 . A package comprising at least two opposite walls which are bonded together along a longitudinally extending bonding seam, each wall comprising at least two bonded˜together wall members, which are folded onto each other about a fold line, characterized in that parts of the walls positioned on either side of the wall members can be moved away from each other in directions extending parallel to the longitudinal direction of the bonding seam, wherein the opposite wall members can be moved apart, bounding an opening that gives access to a space present inside the package.  
     
     
         2 . A package according to  claim 1 , characterized in that the wall members of one wall are positioned on a side of said one wall remote from the other wall, and vice versa.  
     
     
         3 . A package according to  claim 1 , characterized in that a wall member extends parallel to the associated wall.  
     
     
         4 . A package according to  claim 3 , characterized in that the wall member is bonded to the associated wall.  
     
     
         5 . A package according to  claim 1 , characterized in that the wall members of one wall extend in a direction opposed to the direction in which the wall members of the other wall extend.  
     
     
         6 . A package according to  claim 1 , characterized in that the bonded-together wall members of a wall extend in a direction transversely to the longitudinal direction of the bonding seam over at least substantially the entire package.  
     
     
         7 . A package according to  claim 1 , characterized in that the walls of the package are folded double in a direction away from the bonding seam, said folded-together walls being sealed by means of a further bonding seam.  
     
     
         8 . A method of manufacturing a package according to  claim 1 , characterized in that longitudinal sides of a strip-shaped foil are bonded together, at  1  east two pairs of wall members are folded onto each other about fold lines extending parallel to the longitudinal side, the wall members of each pair are bonded together, the pairs of wall members are positioned opposite each other, and the walls positioned on either side of the wall members are bonded together by means of a bonding seam extending transversely to said longitudinal sides.
