も適した包装袋に関する。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a packaging bag having a spout for facilitating the pouring of contents, and particularly to liquids including high-viscosity liquids, powders, granules and the like. The present invention relates to a packaging bag that stores articles that can be poured out from an outlet and is also suitable for refilling.

Description of the Related Art Conventionally, a pump type container is widely used in which a suitable amount of liquid such as shampoo and detergent for dishwashing is discharged by a pump. And in recent years, even if the contents of the pump-type container are gone due to resource saving, the container is not discarded, and the contents filled in the refilling packaging bag are refilled with an empty pump-type container, It is practiced to reuse the pump container many times.

用いられている。As a packaging bag for containing the refilling liquid, for example, as shown in FIG. 6, the peripheral edges of two synthetic resin films on the front and back are sealed 51 except for the spout passage, and then the spout passage 53 is formed. 7. A packaging bag of a type that cuts and opens a sheet, or a synthetic resin film having two front and back sides as shown in FIG.
For example, a packaging bag in which a hollow cylindrical plug body 56 made of synthetic resin is embedded between a plurality of synthetic resin films to provide a projecting spout is used.

用、および形状の制約等の問題が残る。In the former packaging bag, since the packaging bag tends to be inflated by the liquid at the time of pouring, a force in the direction in which the pouring outlet passage is pulled and works, the inner surfaces of the pouring outlet passage are brought into close contact with each other and the pouring outlet is closed. Since the passage tends to be blocked, the liquid does not come out easily, and it cannot be efficiently poured out unless it is held down by hand and squeezed, and when the remaining amount is low, it becomes difficult to pour from the packaging bag. There is a problem with the pouring functionality, such as the amount of residual liquid adhering to the packaging bag is large and the contents are wasted. Also,
Although the latter packaging bag has improved pouring functionality as described above, a synthetic resin molded product is attached to a soft synthetic resin film, and the diameter of the spout may be changed depending on the content. It has to be fitted to the proper one, and problems such as labor, cost, and shape constraint remain.

Figure 2
(See (d)), this method is an effective method for forming the recess forming parts on the front and back of the packaging bag. This is because it is possible to minimize an increase in the thickness of the spout passage due to the hollow forming portion. (5) Arrangement is conceivable, such as arranging a plurality of lines in a plurality of rows in the same direction with respect to the spout passage (see FIG. 2 (e)). Although the spout provided in the packaging bag is provided at the end of the packaging bag in the illustrated example, it may be located at the center of the packaging bag. Further, the recess forming portion may be provided on only one side of the bag or on both sides of the bag.

ましい。The method of forming the depressions forming the depression forming portion 12 is as follows. That is, a method of press-molding a synthetic resin film before forming a bag using a male mold and a female mold is generally used. When aluminum foil is included in the layer structure of the synthetic resin film,
It is possible to form the depressions by a so-called cold foam method in which the mold is not heated, and in the case of a layer structure in which the aluminum foil is not included, heat is applied to the mold (preferably, the glass transition point of the base film). It is preferable to form the depression at the above temperature and at a temperature not higher than the melting temperature of the sealant layer.

Alternatively, the opening portion is exposed by cutting the portion to be opened along the cutting line 14 using a tool such as scissors.
The cut line 14 may overlap the depression forming portion 12,
It doesn't matter if they don't overlap. If the packaging bag is tilted with the spout facing another container and the packaging bag is squeezed, the spout passage 13
Since the hollow forming portion 12 is formed, the inner surfaces of the spout passage are not in close contact with each other, the contents enter the spout passage through the hollow formation portion, and the spout passage is not blocked and is stable. The contents can be transferred from the spout to another container.
