[Prior art]
2. Description of the Related Art Conventionally, contents are stored in a packaging bag made of a laminated film with a part protruding as a spout and used as a container that is easy to discharge. However, having a partly protruding spout has the disadvantage that the packaging bag has an increased height, is easily bent at the body portion, and can easily collapse even as a self-supporting bag having a gusseted bottom. In addition, there is a problem that the spout with a part protruding is narrow and easy to bend, which makes it difficult to discharge the contents. Although the bag which attached A is disclosed, there was a fault that a trunk part bends or falls down by reducing the contents (for example, refer to patent documents 1).

In order to solve the above-mentioned problem, a structure is disclosed in which an exterior body that reinforces the body portion and facilitates the discharge of contents is attached. A trapezoidal front plate and a rear plate are connected to the upper and lower edges of the bottom plate via a crease line, a sealing plate is provided at the tip of the rear plate, and the sealing plate is adhered and bonded to the outer side of the front plate. Thus, an adhesive is applied in advance to the inner surfaces of the front plate and the back plate, and the plastic storage bag is bonded and fixed at a predetermined position. However, in this technique, the pouring portion of the bag itself does not protrude, and the operation is troublesome because the exposed portion of the bag outlet is cut off and opened after breaking the corner of the carton. At the same time, even though it is effective as a liquid-use product or a refill bag, it cannot be resealed in products that are used repeatedly or in products that require moisture resistance. (For example, refer to Patent Document 2).

In addition, as another conventional technique, a packaging bag in which a spout is formed so as to protrude from the upper central portion of the bag is packaged with a paper container. However, when opening, after removing the cover plate of the paper container, the upper part of the packaging bag is cut and opened with a scissors or the like, and the opening operation is complicated, and the upper end of the packaging bag before opening is folded and the paper Since it was stored in the container, there was a drawback that it was difficult to perform the opening operation due to folding. Also, considering the operability of products that require this kind of squeezing, one-handed operation is common, and the width direction dimension is naturally limited, and in the form in which the spout is formed at the center, the spout width is narrow. In other words, there was a drawback that it was difficult to maintain the opening state of the narrow outlet. (For example, refer to Patent Document 3).
