In the present embodiment, the projecting portion 75 extends from the first straight line L1 toward the side seal portion from the deepest portion 42 side of the side recess portion toward the end portion 73b side of the side seal portion side of the tip of the nozzle. After the distance d (see FIG. 3) to the outer edge portion 7b gradually increases, the distance d gradually decreases.
Further, the projecting portion 75 in the present embodiment has a portion where the distance d (see FIG. 3) from the first straight line L1 to the outer edge portion 7b of the side seal portion is the maximum, the deepest portion 42 of the side recess portion. And the end 73b side of the intermediate point between the end portion 73b on the side seal portion side of the front end portion of the nozzle.

Next, as a preferred method of using the pouch container 1 of the present embodiment, a case where the liquid contents accommodated in the pouch container 1 of the present embodiment is refilled into the dispensing container 8 shown in FIG. 5 will be described.
The pouring container 8 shown in FIG. 5 includes a pouring tool 81 having a pouring cylinder 82 and an outer cylinder 83 surrounding the pouring cylinder, and a container body 89, as shown in FIG. The dispensing tool 81 is fixed to the opening of the container main body 89 by a known method such as fitting or screwing.
The pouring tool 81 includes a pouring cylinder 82 projecting upward from the partition plate 84 and an outer cylinder 83 coupled to the pouring cylinder 82 via the partition plate 84. A concave liquid recovery space 85 is formed therebetween, and a liquid recovery opening 84 a is provided at the bottom of the liquid recovery space 85. Further, the dispensing cylinder 82 is formed with an axial separating portion 82a that reaches the liquid recovery opening 84a from its upper end. The outer cylinder 83 of the dispensing tool 81 has a thread 83a on the outer surface, and is capable of being screwed into a measuring cap (not shown) in a detachable manner. The tip of the dispensing cylinder 82 protrudes from the upper edge of the outer cylinder 83.

  When using the contents in the dispensing container 8, when the liquid in the container body 89 is poured into the measuring cap through the dispensing cylinder 82 and weighed, and as a result, it is determined that it is larger than the required amount The excess amount can be returned into the liquid recovery space 85. The liquid returned to the liquid recovery space 85 returns to the inside of the container main body 89 through the liquid recovery opening 84a or the opening 84a and the separation portion 82a. When a small amount of liquid adheres to the measuring cap and the opening of the container body 89 is closed with the measuring cap, or the dispensing container 8 is turned upside down with the measuring cap attached, and then returned to its original position. Even in such a case, the liquid that has moved to the cap side returns to the inside of the container main body 89 through the liquid recovery opening 84a or the opening 84a and the separation portion 82a.

A preferred operation procedure for refilling the liquid contents in the pouch container 1 into the dispensing container 8 will be described. First, as shown in FIG. 4 (a), the excision part 72 is cut out along the cutting guide line 71. The nozzle 7 having the spout opened at the distal end portion 73 is generated, and in this state, the side recess portion 41 located on the lower side of the nozzle 7 is replaced with the upper edge portion of the outer cylinder 83 located on the front surface of the separating portion 82a. Put it on P1. By doing in this way, the nozzle 7 of the pouch container 1 is directed downward, and the contents in the pouch container 1 flow out of the nozzle 7, but the pouch container 1 is centered on the part P1 and is indicated by the arrow A in FIG. Further rotation in the direction can improve the outflow rate of the contents.
Observing the refilling behavior of consumers, in most cases, trying to put out the contents to the end, tilting the pouch upside down from the middle to the second half of the refilling operation. According to the pouch container 1 of the present embodiment, as shown in FIG. 4 (b), the upper hollow portion 31 located on the upper side of the nozzle 7 of the pouch container 1 faces the separation portion 82 a in the dispensing cylinder 82. After rotating until it hits the upper edge P2 of the part, even if it is further rotated, the lower protrusion 75 of the nozzle 7 is kept in contact with the inner surface of the outer cylinder 83, and the lower side of the nozzle 7 is The outer cylinder 83 is prevented from coming off. Further, when the angle θ1 formed by the first straight line L1 and the second straight line L2 described above is 30 ° or less, even if the pouch container 1 is further rotated around the upper edge portion P2, the protruding portion Since the 75 movement trajectory abuts against the inner wall of the outer cylinder 83 so as to be directed in a horizontal direction, it is possible to more effectively prevent the nozzle 7 of the pouch container from easily coming out of the outer cylinder 83. .

By such an action, the nozzle 7 is inserted into a space between the inner surface of the extraction tube 82 and the inner surface of the outer tube 83 facing each other with the separation portion 82a interposed therebetween (hereinafter referred to as “insertion site”). Thus, the liquid in the pouch container 1 can be efficiently refilled into the dispensing container 8 without spilling around.
In addition, the usage method of the pouch container 1 of the present invention is not limited to the above-described method. For example, after the cutting guide line 71 is cut, the nozzle 7 having a spout opened at the tip is generated. The nozzle 7 can be directly inserted into the insertion site so as to be in a state as shown in FIG.

  From the viewpoint of making it difficult for the nozzle 7 to be removed from the insertion site of the dispensing container 8, the angle θ1 formed by the first straight line L1 and the second straight line L2 is preferably 30 ° or less, more preferably 15 ° or less. . The lower limit value of the angle formed is 0 °. The angle θ1 formed is 0 °, which means that the first straight line L1 and the second straight line L2 are parallel.

From the viewpoint of making it difficult for the nozzle 7 to be removed from the insertion site of the dispensing container 8, the linear distance from the deepest portion 32 of the upper recess portion 31 to the end portion 73a on the upper seal portion 3 side of the tip portion 73 of the nozzle is 7 mm. The upper limit is preferably 15 mm or more, and the upper limit is preferably 25 mm or less, more preferably 20 mm or less.
From the same viewpoint, the linear distance from the deepest portion 42 of the side recess 41 to the end portion 73b on the side seal portion 4 side of the tip portion 73 of the nozzle is preferably 5 mm or more, more preferably The upper limit is preferably 20 mm or less, and more preferably 15 mm or less.
The thickness of the side seal part 4 and the thickness of the upper seal part 3 are preferably 1.5 mm or more, more preferably from the viewpoint of suppressing the deformation of the seal part and obtaining a sufficient locking force by the protrusions. It is 3.5 mm or more, preferably 10 mm or less, more preferably 6 mm or less. Note that only the thickness of one of the side seal portion 4 and the upper seal portion 3 may be within the above preferable range.

  Further, in the pouch container 1 of the present embodiment, as shown in FIG. 3, the third straight line L3 parallel to the outer edge portion 4b of the side seal portion 4 located below the side recess portion 41, and the above-mentioned The angle θ2 formed with the second straight line L2 is 55 degrees or less. Therefore, the nozzle tip of the pouch can be smoothly inserted into the dispensing cylinder, and at the same time, the state in which the nozzle is inserted into the spout can be maintained even if the pouch is greatly inclined. From the viewpoint of ensuring such an effect, the angle θ2 formed by the third straight line L3 and the second straight line L2 is preferably 50 ° or less, and more preferably 45 ° or less. The lower limit of the angle θ2 is 30 °, but is preferably 40 ° or more.

  Further, the projecting portion 75 in the pouch container 1 of the present embodiment extends from the first straight line L1 to the outer edge portion from the deepest portion 42 side of the side recess portion 41 toward the lower end portion 73b side of the tip portion of the nozzle. Therefore, when the pouch is rotated around the upper edge P2, the side depression 41 does not interfere with the upper part of the outer cylinder 83, so that the protrusion d 75 can firmly contact the inner wall of the outer cylinder 83.

  Further, the protruding portion 75 in the pouch container 1 of the present embodiment has a portion where the distance d from the first straight line L1 to the outer edge portion of the side seal portion is the maximum, the deepest portion 42 of the side recess portion and the nozzle. Since the end portion 73b is located closer to the end portion 73b than the intermediate point between the end portion and the end portion 73b, the protrusion 75 is farther from the center P2 when the pouch is rotated around the upper edge portion P2. Since it abuts against the inner wall of the outer cylinder 83 at the position, the rotational moment increases and the nozzle can be firmly fixed.

Further, the protrusion 75 preferably has a maximum distance d from the first straight line L1 to the outer edge of the side seal portion of 1 mm to 5 mm, particularly 2 mm to 4 mm.
Moreover, the distance d1 (refer FIG. 4) between the deepest part 32 of the upper hollow part 31 and the deepest part 42 of the side hollow part 41 is the linear distance d3 (refer FIG. 4) between the site | part P1 and site | part P2 of the extraction container. It is preferably 80% or more and 120% or less of (see FIG. 4), more preferably 90% or more and 110% or less.
Moreover, the maximum distance d2 between the deepest part 32 of the upper hollow part 31 and the protrusion part 75 is 90% or more and 120% or less of the linear distance d3 between the site | part P1 and site | part P2 of the extraction container. Preferably, it is 100% or more and 110% or less.

  Further, as shown in FIG. 2, the pouch container 1 of the present embodiment is embossed on the pair of side wall films 2 and 2 positioned in the flow path 70. Specifically, each of the pair of side wall films 2 and 2 is formed by embossing with an arrow-shaped convex portion 21 that swells away from each other and concave portions 22 and 22 that are recessed toward each other. . One or both of the pair of side wall films 2 and 2 positioned in the flow path 70 are embossed so as to increase the rigidity of the portion between the upper seal portion and the lower seal portion forming both ends of the nozzle. When refilling, the way the nozzle bulges out is stable and less likely to spill.

Moreover, as shown in FIG. 6, it is also preferable to color the upper dent part 31 and the side dent part 41 in the refillable pouch container of the present invention to enhance the visibility.
Increasing the visibility of the upper and side dents can give consumers the awareness that the upper dent 31 and the side dent 41 provided on the pouch are refilled against the centers P1 and P2, respectively. .
When coloring the upper hollow part 31 and the side hollow part 41, both may be colored in the same color, and you may color both in a different color. Moreover, you may color only any one of an upper hollow part and a side hollow part. Further, as shown in FIG. 6, it is preferable to locally color the vicinity of the deepest portions of both hollow portions, but it is preferable to have a wider range centered on the deepest portion. It may be colored. Further, only the outer edge portion of the seal portion may be colored, or a wider range such as the full width of the seal portion may be colored. In FIG. 6, the portion indicated by reference numeral 9 is a colored portion.
Further, in coloring the upper dent portion 31 and the side dent portion 41, it is preferable to color the same color in both, but in order to intuitively understand that they are in contact, A similar color is preferred.

The present invention is not limited to the above-described embodiment, and various modifications can be made.
For example, in the refillable pouch container of the present invention, as shown in FIG. 7, the protruding portion 75 may have a straight portion 75a. In the embodiment shown in FIG. 7, the linear portion 75 a of the protruding portion 75 is substantially parallel to the linear outer edge portion 7 a on the upper side of the nozzle 7, and the protruding portion 75 itself has a trapezoidal shape.
In addition, as shown in FIG. 8, a second protruding portion 76 that protrudes outward can be formed in the vicinity of the tip of the nozzle in the linear outer edge portion 7 a on the upper side of the nozzle 7. According to the refillable pouch container shown in FIG. 8, in the state shown in FIG. 8B, even if a force is applied to rotate the container in either the left or right direction, the projecting portion 75 is the outer cylinder. The second protrusion 76 is pressed against or engaged with the inner surface of the dispensing cylinder 82. Therefore, the state where the nozzle is inserted into the insertion site of the dispensing container is stably maintained.
