[0002]

2. Description of the Related Art Conventionally, this type of packaging bag contains and sells refill products from the viewpoint of waste disposal problems and resource saving. Products made of these refill products and the like are generally packaged in a four-side seal bag or a stand bag made of a plastic film.

[0003] For example, in a conventional packaging bag, in order to enhance the independence of the packaging bag for accommodating contents such as liquid and powder, a folded portion is formed by folding a side portion of the packaging bag into the inside thereof. There is a type in which four corners corresponding to folding edges are linearly sealed to form side seal portions.

In order to provide a spout for transferring the contents in the packaging bag to a container such as a bottle, these packaging bags are manufactured by processing the sealing shape of the closing opening into a shape suitable for pouring out. Alternatively, there is, for example, one provided with a separately manufactured spout made of an injection molded body.

However, in the above-described packaging bag, the contents protrude and spill when the packaging bag is opened due to the hand of holding the packaging bag when pouring out the contents or the pressure due to the weight of the contents. In the case where a separate spout is attached, an injection molding process for forming a separate spout is required, and the production cost is increased.

In order to solve the above-mentioned drawbacks, the present applicant has developed a folding bag in which a side portion is folded inside by a folding line and a folded portion is formed by folding one end of the folded portion outward. JP-A-8-2630, entitled "Packaging bag with spouting part and hermetically sealed package with said pouch", characterized in that a spouting part comprising a spout is formed.
