Pouch, lidded container, and tube

Abstract

A first packaging material includes at least one layer located in both a first region and a second region. A second packaging material includes at least one layer located in both the first region and the second region. An outline of a communication part that extends from the hole to the outer edge of the pouch includes a first line and a second line. The communication part includes a first portion and a second portion. The first position includes a portion where the first line and the second line have a spacing from each other that decreases with increasing distance from the outer edge of the pouch toward the hole. The second portion is located between the first portion and the hole, and includes a portion where the first line and the second line have a spacing from each other of less than or equal to 2.0 mm.

         8 . A lidded container, the lidded container having a containment part sealed by joining a first packaging material and a second packaging material together, the first packaging material constituting a lid, the second packaging material constituting a container, the lidded container comprising:
 a first region overlapping the containment part in plan view;   a second region located between the containment part and an outer edge of each of the lid and the container in plan view, the second region including a seal that joins the first packaging material and the second packaging material together;   a hole located in the second region and penetrating the first packaging material and the second packaging material; and   a communication part extending from the hole to the outer edge of each of the lid and the container and penetrating the first packaging material and the second packaging material,   wherein the first packaging material includes at least one layer located in both the first region and the second region,   wherein the second packaging material includes at least one layer located in both the first region and the second region,   wherein an outline of the communication part that extends from the hole to the outer edge of each of the lid and the container includes a first line and a second line, and   wherein the communication part includes
 a first portion including a portion where the first line and the second line have a spacing from each other that decreases with increasing distance from the outer edge of each of the lid and the container toward the hole, and 
 a second portion located between the first portion and the hole and including a portion where the first line and the second line have a spacing from each other of less than or equal to 2.0 mm. 
   
     
     
         9 .

         10 - 11 . (canceled) 
     
     
         12 . The lidded container according to  claim 8 , wherein in the second portion of the communication part, the first line and the second line are not in contact with each other. 
     
     
         13 . The lidded container according to  claim 8 , wherein in the second portion of the communication part, the first line and the second line are at least partially in contact with each other. 
     
     
         14 . The lidded container according to  claim 13 , wherein a portion of the communication part where the first line and the second line are not in contact with each other is longer than a portion of the communication part where the first line and the second line are in contact with each other. 
     
     
         15 . The lidded container according to  claim 8 , wherein a middle line linearly extends from the hole toward the outer edge of each of the lid and the container, the middle line running in the middle between the first line and the second line. 
     
     
         16 . The lidded container according to  claim 8 , wherein each of the first line and the second line includes a straight portion extending from the first portion to the second portion. 
     
     
         17 . The lidded container according to  claim 16 , wherein the straight portion of each of the first line and the second line extends from the hole to the outer edge of each of the lid and the container. 
     
     
         18 . The lidded container according to  claim 16 , wherein an extension line of the straight portion of each of the first line and the second line intersects the hole. 
     
     
         19 . The lidded container according to  claim 16 , wherein each of the first line and the second line includes a straight line inclined relative to a middle line, the middle line running in the middle between the first line and the second line.
