Bag

Abstract

A bag for use with at least one wicket pin of an automatic bag filling equipment. The bag has a first side wall of a film material with a wicket mounting part. The wicket mounting part has at least one hole for mounting the bag on at least one of the at least one wicket pins of the bag filling equipment. The bag has a second side wall with an open part of an open material. The second side wall is joined to the first side wall such that the bag has an inside and an opening. The second side wall has a film part of a film material for facilitating the automatic opening of the bag.

1 . A bag for use with at least one wicket pin of an automatic bag filling equipment, said hag at least comprising: 
 a first side wall of a film material having 
 a wicket mounting part with at least one hole for mounting the bag on at least one of the at least one wicket pins of the bag filling equipment;  
   a second side wall, having 
 an open part of an open material  
   which second side wall is joined to said first side wall such that the bag has an inside and an opening    characterised in that    said second side wall has a film part of a film material for facilitating the automatic opening of the bag.    
     
     
         2 . A bag as claimed in  claim 1 , wherein the film part of the second side wall is a strip shaped part located near the opening of the bag.  
     
     
         3 . A bag as claimed in  claim 1  or  claim 2 , wherein said wicket mounting part of the first side wall has at least one local weakening near at least one hole.  
     
     
         4 . A bag as claimed in any one of the preceding claims, wherein the first and second side walls are secured to each other without folding overlap.  
     
     
         5 . A bag as claimed in any one of the preceding claims, wherein the first side wall has an extension, which extension is folded along at least one fold line to overlap and enclose a portion of the second side wall, said extension being secured to the second side wall.  
     
     
         6 . A hag as claimed in  claim 5 , wherein said extension is folded along at least two fold lines, such that at least three layers of film material overlap each other.  
     
     
         7  A bag as claimed in  claim 5  or  6 , wherein said overlapped and enclosed portion of the second side wall extends to at least one of said fold lines.  
     
     
         8 . A bag as claimed in  claim 5  or  6 , wherein said overlapped and enclosed portion of the second side wall extends to an edge of said extension.  
     
     
         9 . A bag as claimed in any one of the preceding claims, wherein the film material is a synthetic material, such as polypropylene or polyethylene.  
     
     
         10 . A bag as claimed in any one of the preceding claims, wherein the open material is a cross-laminated open fabric.  
     
     
         12 . A bag as claimed in any one of the preceding claims, wherein the open material is selected from a group comprising: knitted, woven and extruded open materials.  
     
     
         13 . A bag as claimed in any one of the preceding claims, wherein the open part of the second side wall has a larger surface area than the film part of the second side wall.  
     
     
         14 . A method for filling and closing a bag as claimed in any one of claims  1 - 13 , the method comprising: 
 hanging the bag on a wicket mounting part;    opening the bag with a means engaging on the first side wall of the bag and a suction means engaging on the film part of the second side wall of the bag;    filling the bag through the opening of the bag; and    closing the bag.
