Packaging bag with pour spout

Abstract

To provide a packaging bag with pour spout which can easily pour out content even if the fluidity is pour and which can reduce residual content. A packaging bag 1 with pour spout wherein the pour spout 10 flow path 11 established in a top part of the packaging bag 1 is partitioned by sealed regions 5 a , 7 made by sealing two sheets of film 2, 3 , and a shape retaining member 12 which separates these 2 sheets of film 2, 3 is established in the flow path 11 of the pour spout 10 ; wherein the shape retaining member 12 ensures that a gap 16 a , 16 b will form between the sealed regions 5 a , 7 which partition both sides of the flow path 11 along the whole length, and the shape retaining member 12 is fixed with regards to only one film 2 of the two sheets of film 2, 3.

1 . A packaging bag with pour spout wherein the pour spout flow path established in a top part of the packaging bag is partitioned by sealed regions made by sealing two sheets of film, and a shape retaining member which separates these 2 sheets of film is established in the flow path of the pour spout; wherein the shape retaining member ensures that a gap will form between the sealed regions which partitions both sides of the flow path along the whole length, and the shape retaining member is fixed with regards to only one of the two sheets of film.  
   
   
       2 . The packaging bag with pour spout according to  claim 1 , wherein the shape retaining member attaching region, where the shape retaining member is attached to one film, has a form which extends in the longitudinal direction of the shape retaining member.  
   
   
       3 . The packaging bag with pour spout according to  claim 1 , wherein the shape retaining member is a tube open at both ends along the flow path of the pour spout.  
   
   
       4 . The packaging bag with pour spout according to  claim 1 , wherein the two sheets of film have an expanded region which swells outward in the area of the shape retaining member.  
   
   
       5 . The packaging bag with pour spout according to  claim 4 , wherein the expanded region extends to the content storing region.  
   
   
       6 . The packaging bag with pour spout according to  claim 1 , wherein the pour spout is established in the corner region of the packaging bag, the flow path of the pour spout is pointed at an upward angle from the packaging bag, an opening guide line which guides the opening in a direction which intersects with the flow path of the pour spout is established in the seal region on one side of the pour spout, the end region of the opening guide line extends parallel to the bottom side of the packaging bag, and the end region of the opening guide line is established in a location such that the extended line does not intersect with the shape retaining member.  
   
   
       7 . The packaging bag with pour spout according to  claim 6 , wherein the distance from the extended line of the end region of the opening guide line to the shape retaining member is within a range of 1 to 4 mm.
