  • Patent number: 11878841
    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.

  • Publication number: 20230026514
    Abstract: The present invention provides a laminated sheet for manufacturing a packaging container. The laminated sheet comprises a pair of plastic sheets, a barrier sheet, a barrier region, an easily peelable region, and a fixing region. The barrier sheet has flexibility and is disposed between the pair of plastic sheets. The barrier region is formed by overlapping the pair of plastic sheets and the barrier sheet with each other. The easily peelable region is provided in the barrier region. The fixing region is located in a circumference of the easily peelable region, in which the pair of plastic sheets are fixed to each other directly and/or via the barrier sheet. A peel strength between the pair of plastic sheets and the barrier sheet in the easily peelable region is smaller than a direct peel strength between the pair of plastic sheets and/or a peel strength between the pair of plastic sheets via the barrier sheet in the fixing region.
