Title:
POUCH, LIDDED CONTAINER, AND TUBE
Document Type and Number:
WIPO Patent Application WO/2021/162116
Kind Code:
A1
Abstract:
A first packaging material contains at least one layer positioned in both a first region and a second region. A second packaging material contains at least one layer positioned in both the first region and the second region. A hole includes a proximal position where the distance to the outer edge of a pouch is shortest in a center of gravity direction in which a center of gravity line that passes through the center of the pouch and the center of the hole extends. A communication part is connected to the hole at a position that is separated from the proximal position in a direction orthogonal to the center of gravity direction. The contours of the communication part from the hole to the outer edge include a first line and a second line. The first line is positioned on a proximal position side with respect to the second line. In the center of gravity direction, the distance from a first connection point, which is where the first line connects to the hole, to the outer edge is greater than the distance from the proximal position to the outer edge.
