ないので、近年、大量に使用されるようになってきた。As a solution to this problem, a single-layer or multi-layer film of polyethylene, ethylene-vinyl acetate copolymer, ethylene-vinyl alcohol copolymer, polyamide, polyester, etc. is polymerized and the periphery is welded to form a bottom portion. Standing pouch (sometimes called a self-supporting packaging bag) with a cap that has the same structure as the bottle on the upper part (sometimes called a self-supporting packaging bag) is easy to cost, does not have a bulky volume, and is resource-saving. Therefore, it has been used by replacing a part of the demand for bottles. As one of them, two rectangular plastic films developed and commercialized by the present applicant are polymerized and the periphery thereof is welded to form a bag for containing a fluid, and the non-welded portion is welded to the upper welded portion. There is a fluid packaging bag with an outflow passage formed by connecting a base end of the outflow passage to the inside of the bag and arranging a closed tip of the end in a corner portion. This has a structure as shown in FIG.
As you can see from the shape, after filling the fluid, the upper corner is cut to open the tip of the outflow passage, and when the bag is grasped and the fluid in the bag is pressed, the fluid flows out from the outflow passage, while the bag When the force to grasp is weakened, the outflow of fluid stops, and if the fluid remaining in the outflow passage is squeezed out, the fluid will flow out of the outflow passage even if the bag is placed at any position unless the fluid in the bag is pressed. Not a fluid packaging bag with a self-closing outflow passage. When using this product, follow the operation and process as shown in Fig. 2. If you press the bag, the contents will flow out, and if you stop the pressing, the flow will stop, so you do not have to bother with the cap each time. Since, like a bottle, the contents do not flow out due to a fall and stain the surroundings and the contents are not lost, it has come to be used in large quantities in recent years.

も、上記の問題がある。However, in the conventionally used standing pouch with a self-closed outflow passage, when pressure is applied to the pouch, the film below the inlet of the outflow passage portion swells, and the outflow passage portion is bent, so that the outflow passage portion is bent. Was closed and the condition was not stable (the contents did not come out at all or were released all at once). The above problem also occurs in a refill pouch that does not have a self-closed outflow passage as shown in FIG. 1B and has a standing structure at the bottom.

No. 505322. As a result, the bending of the outflow passage part was reduced and the contents became easier to come out. However, as shown in Fig. 3 (B), when the body part of the pouch was gripped, the pressure tended to concentrate at the pinch point, so the edge was broken. In some cases (film breaks from the edge of the sealing surface) and bag breakage.

る。In order to solve the problem, as shown in FIG. 4, a pouch is provided around the base portion 9 (synonymous with base end, inlet, etc.) of the content pouring passage 8 (synonymous with outflow passage). The pouch with a constriction point 15 that joins the seals (Fig. C), the pouch in which the sealing surface inside the pouch is joined with another short material as the constriction point 15 (Fig. A), the sealing surface inside the pouch An improvement of a pouch (FIG. B) and the like joined with another long material is disclosed in JP-A-7-41016. However, claim 1 of the publication and FIG. 4C of the publication.
As shown in Fig. 5, there is a large gap (gap) between the left and right ends of the constriction point 15 and the inner surface of the pouch, and the body of the pouch is gripped to apply pressure to the pouch and bend the outflow passage. When trying to prevent, if the contents of the pouch are full, it is possible to achieve the purpose to a certain extent, but as the contents of the pouch become less, it becomes difficult to apply pressure evenly to the contents, The fluid that has been raised upwards from the left and right gaps flows backward, and it is not possible to apply sufficient pressure to the vicinity of the root portion 9 of the content pouring path 8, so the bending of the outflow passage portion is reduced and the content is easily ejected. It is difficult to fully achieve the initial goal of.

The white part inside the shaded part around it is the part provided parallel to the horizontal cross section of the bag body. The circular part to the right of the white part is the hole for inserting the fluid filling nozzle. The perspective view (B) of FIG. 7 is a perspective view showing a shape in the process of manufacturing the pouch of the present invention, in which the plan view (A) is folded in half and superposed on two polymer films. The plan view (C) is
It is provided at a position slightly below the welded portion on the upper side of the bag and in parallel with the horizontal cross section of the bag body, and the welded portion is located below.

The rectangular shape of the partition film (A) has the merit of lower material cost and manufacturing cost, but the area of the partition film (A) cannot be increased, and the expansion to a flat surface near the left and right welded parts of the rectangle is somewhat. There are disadvantages such as inferiority. If the left and right welded parts of the rectangle are made elliptical, the development on a flat surface will be fine. On the other hand, when the partition film (A) has an elliptical shape, the material cost and the production cost are slightly high, but the area of the partition film (A) can be increased.
There are merits such as the development on the plane near the left and right welds of the ellipse being clean.

Self-closed outflow passage In the present invention, the self-closed outflow passage is a bent fluid passage as indicated by reference numeral 8 in FIG. 1, and includes (A), (B), (C), ( As shown in D), the outlet of the outflow passage can be opened along the guide line 5 with scissors (A), and when the bag is grasped and the fluid in the bag is pressed (B), the fluid flows out from the outflow passage. (B) When the force of gripping the bag is weakened, the outflow of the fluid is stopped. Then, when the fluid remaining in the outflow passage is squeezed out (C), the fluid in the bag is not pressed even if the bag is placed at any position. As long as it is a liquid passage having a function of preventing fluid from flowing out of the outflow passage. Therefore, after the fluid of the contents has flowed out of the bag, the fluid of the contents does not flow out even if the bag is laid down or the bag is hung with the outlet of the outflow passage facing downward. As in the case, after use, it is convenient to save time and effort to close the cap each time. The shape of the self-closing outflow passage is, for example,
S, C, V, L, N, M, W, black, black, green, black,
One, three, two, three, seven, etc., or a modification thereof, which is not a straight line, but a bent portion that creates resistance to the flow of liquid in the middle of the outlet to the outlet of the outflow passage. It is necessary to have In order to generate a large resistance, the width of the outflow passage may be narrowed and the bent portion may be formed in many places. In order to generate a small resistance, the width of the outflow passage may be increased and the bent portion may be formed in one place. Good.

ある。The width of the outflow passage varies depending on the capacity and size of the bag, but the width is preferably about 2 to 20 mm. In addition, since the outflow passage is formed between two plastic films, it is usually designed so that the films are in close contact with each other when the fluid does not pass through. It is also possible to inflate by a predetermined amount to the side so as to project. When it is projected, it has the effect of reducing the resistance to the flow of liquid, but if the amount of projection is too large, the fluid of the contents is allowed to flow out of the bag, and then the bag is laid down or the outlet of the outflow passage is closed. If the bag is hung down, the contents will flow out from the outlet of the outflow passage even if the contents in the bag are not pressed.
