Package body for pouch container and pouch container package

Abstract

A pouch container packaging body and a pouch container package with which a container body can be more reliably opened. The packaging body includes a container body including a top sheet covering the container body at a top side and a spout fixed to an outer surface of the top sheet and including a dispensing space extending axially. The spout includes a fixed portion on the top sheet, a rotating portion to rotate the fixed portion, and a cutting portion to cut the top sheet. The top sheet includes a flat portion where the fixed portion is fixed. The cutting portion is positioned away from the flat portion in an initial state and moves while rotating in a direction from an external surface to an internal surface of the flat portion in response to rotation of the rotating portion, and cuts the flat portion.

1 . A pouch container packaging body, comprising:
 a container body including a top sheet covering the container body at a top side; and   a spout fixed to an outer surface of the top sheet and including a dispensing space extending in an axial direction,   wherein the spout includes a fixed portion fixed to the top sheet, a rotating portion configured to rotate relative to the fixed portion, and a cutting portion configured to cut the top sheet,   the top sheet includes a flat portion that is flat in a state where the fixed portion is fixed, and   the cutting portion is positioned away from the flat portion in an initial state and moves while rotating in a direction from an external surface to an internal surface of the flat portion in response to rotation of the rotating portion, and cuts the flat portion.   
     
     
         2 . The pouch container packaging body according to  claim 1 , wherein
 the fixed portion includes a flange portion having a flat and annular shape, and   the flange portion is fixed to an outer surface of the top sheet.   
     
     
         3 . The pouch container packaging body according to  claim 1 , wherein
 the spout includes a rotation angle regulator configured to regulate rotation of the rotating portion to less than 360° after the cutting portion starts to cut the top sheet.   
     
     
         4 . The pouch container packaging body according to  claim 1 , wherein
 the rotating portion includes a first cylindrical portion configured to screw into the fixed portion, and   the cutting portion is formed on an endmost side in the axial direction of the first cylindrical portion.   
     
     
         5 . The pouch container packaging body according to  claim 4 , wherein
 the cutting portion is inclined and protrudes further in a rotation direction closer to a tip end in the axial direction.   
     
     
         6 . The pouch container packaging body according to  claim 4 , wherein
 the endmost side in the axial direction of the first cylindrical portion is formed into an inclined edge, the inclined edge increasing in inclination, from a tip end side of the cutting edge to a base end in the axial direction, along a direction opposite to a rotation direction.   
     
     
         7 . The pouch container packaging body according to  claim 1 , wherein
 the top sheet is formed with an easy-cut line configured to be easier to cut than adjacent portions, and   the easy-cut line overlaps at least a portion of a rotation path of the cutting portion when viewed along the axial direction.   
     
     
         8 . The pouch container packaging body according to  claim 7 , wherein
 the easy-cut line includes an outer guide portion located radially outward from the rotation path of the cutting portion and provided near a terminal of the rotation path of the cutting portion as viewed along the axial direction.   
     
     
         9 . The pouch container packaging body according to  claim 1 , wherein
 the spout includes a band-like portion being removable and configured to prevent rotation of the rotating portion relative to the fixed portion.   
     
     
         10 . A pouch container package comprising:
 the pouch container packaging body of  claim 1 ; and   a packaged material stored in the container body in a sealed state.
