Definitions

  • the present invention relates to standing pouches.
  • the standing pouch includes a body portion, an upper passage portion, a side passage portion, an upper closing seal portion, a side closing seal portion, a chuck, and contents.
  • the contents are, for example, liquids used for cooking food.
  • the body forms a storage space in which the contents are placed.
  • the upper passage portion is positioned upward with respect to the body portion. Before the upper closing seal is formed on the standing pouch, the upper passage opens upward. With the upper closure seal formed on the standing pouch, the upper closure seal closes the upper passageway.
  • the side passage part is located in the widthwise direction with respect to the body part. Before the side closing seal is formed on the standing pouch, the side passage is open in the widthwise direction. With the side closure seal formed on the standing pouch, the side closure seal closes the side passageway. A chuck is provided between the upper closure seal and the barrel. Contents are accommodated in the accommodation space.
  • standing pouches are manufactured through the following processes.
  • An intermediate product is manufactured that includes a body, an upper passageway, a side passageway, an upper closure seal, and a chuck. Contents are supplied to the accommodation space from the side passage portion. A laterally closed seal is formed. Containment space is closed.
  • standing pouches containing contents are used as follows. A portion of the upper passage containing the upper closure seal is separated from another portion of the upper passage leading to the barrel. The chuck is released. Another content is thrown into the containing space. Chuck is closed. A heating means heats the standing pouch. The content housed in the housing space is cooked as it is heated.

  • a side interior is provided in at least one of a portion of the side passage positioned in the width direction with respect to the first seal portion and a portion of the accommodation space positioned in the width direction with respect to the side passage. Therefore, the side passages are less likely to expand during heating of the standing pouch. It is difficult for the contents to flow from the storage space toward the side passage. Therefore, the shape of the standing pouch is less likely to be deformed due to heating.
  • the lateral interior is provided to fit in the lateral passageway. According to this standing pouch, for example, the following effects can be obtained. As the standing pouch is heated, the storage space is easily expanded.
