  • Publication number: 20240132253
    Abstract: The present invention provides a sheet material container being made of a sheet material and including a body portion and a bottom portion that is to be disposed on a placement surface, and the sheet material including a plurality of film layers. A body portion sheet that constitutes the body portion includes a bonding portion where peripheral edge portions of the sheet materials are bonded. In a bottom surface sheet that constitutes the bottom portion, a non-adhesive region is provided in the plurality of film layers. The non-adhesive region forms a bottom filler-filled portion. The bottom filler-filled portion extends annularly around a non-filled portion, and includes at least three protruding leg portions that are to be placed on the placement surface so as to allow the container to stand by itself. The protruding leg portions protrude toward the placement surface past other portions in the bottom filler-filled portion due a leg forming portion.

  • Patent number: 11548689
    Abstract: A sheet container has, formed in the bottom face of the container body, a non-attached part where the film layers are left partially unattached to each other. An filled part is formed by enclosing a filler between the film layers at the non-attached part. A side part of the filled part is a side bulging part bulging toward the skirt part. The side bulging part presses a pressed part above the lower edge of the skirt part from the inside toward the sideward. The lower edge of the skirt part is disposed inwardly from the pressed part.
