DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the standing pouch of the present invention will be described below with reference to the drawings. 1 to 3 show one embodiment of a standing pouch according to the present invention. FIG. 1 is an overall perspective view and FIG.
3 is an enlarged view of a main part, and FIG. 3 is a sectional view taken along line AA of FIG. As shown in FIG. 1, the standing pouch 1 according to the present embodiment includes two side surfaces 2 and 2 and a bottom surface 3 having a space S at a lower portion, and a cross-sectional area of a cross section gradually decreases as going upward. The side portions 2, 2 are formed so as to form a three-dimensional shape.
Is mainly composed of a pouch main body 4 to which an upper end is adhered. The pouch main body 4 is filled with a liquid composition as a content, and a take-out portion 5 of the content is provided at an upper end corner of the pouch main body 4. Is provided. A pouring cylinder 6 is inserted into the take-out portion 5, and the pouring port is opened by cutting the tip 5 a of the take-out portion 5.

Hereinafter, the standing pouch 1 will be described in more detail. The pouch body 4 is formed of a bottom portion 3 having a space S at a lower portion, and both side portions 2 and 2 formed of the same material and connected to a peripheral end of the bottom portion 3 and has a liquid composition therein. Is filled so that it can stand alone. The pouch body 4 has a three-dimensional shape in which the cross-sectional area of the cross section gradually decreases as it goes upward.

As shown in FIG. 2, the content take-out portion 5 is formed so as to protrude upward from the upper end corner of the pouch main body 4 at an angle of about 45. A capsule-like communication space 7 formed by disposing the depressions formed in the side parts 2 and 2 in close proximity to each other is formed. The communication space 7
Is connected to an internal space 8 filled with the liquid composition at an end 7a on the inner side of the pouch main body 4, and the other end 7b and both side ends are surrounded and sealed by a joining portion 9. . Note that, in FIG. 2, the illustration of the side surface portion 2 b on the near side in the extracting unit 5 is omitted.

The discharge cylinder 6 is a plastic cylinder having a predetermined thickness, and its outer diameter is substantially equal to the inner diameter of the communication space 7. The outer peripheral surface is disposed in the communication space 7 with the outer peripheral surface being in close contact with the inner peripheral surface of the communication space 7. The pouring cylinder 6 in the communication space 7 is
A part 10 of the outer peripheral surface is welded to the inner wall surface of the communication space 7 and fixed to a substantially central portion in the length direction of the communication space 7.
The outlet of the contents is opened by cutting off the tip of the take-out section 5 having such a configuration. More specifically, a position (indicated by a dashed line B in FIG. 2) of the communication space 7 from the tip of the extraction portion 5 is cut with a pinch or the like so that the spout surrounded by the communication space 7 is opened. It is supposed to. The above configuration is the same as that of a conventionally known standing pouch.

Thus, in the standing pouch 1 of the present embodiment, the content filled in the pouch body 4 contains 0.1% to 50% of a surfactant and has a viscosity (20 ° C.). The liquid composition is 15 cp to 1000 cp, and the inner diameter W (see FIG. 3) of the pouring cylinder 6 provided in the take-out section 5 is 8 mm to 13 mm. here,
The surfactant is equivalent to the surfactant measured according to JIS K3362.5.7.

The viscosity (20 ° C.) of the liquid composition is 15 c
If it is less than p, it becomes difficult to control the outflow speed of the contents, and when the standing pouch is used as a refill container for refilling, the contents can be squirted and scattered with a simple push, or the container may be rapidly deformed. Therefore, the refilling operation cannot be performed with a sense of security because the spout may come off the inlet of the container to which the spout is transferred. On the other hand, when the viscosity is 1000 cp or more, there are inconveniences such as liquid dripping from the spout and difficulty in discharging the entire amount of the liquid composition in the container. In addition, the dispensing speed is slow, and a quick refilling operation becomes difficult. In the case where the container to be transferred has an inlet having a sufficiently large diameter and some liquid may be scattered, the viscosity (20 ° C.) of the liquid composition should be less than 15 cp. Can also.

If the value of the inner diameter W (see FIG. 3) of the pouring cylinder 6 is less than 8 mm, the liquid composition of the contents is not discharged well, and the refilling operation cannot be performed quickly. In addition, dripping or ejection of the liquid may occur. On the other hand, if the inner diameter of the pouring cylinder 6 exceeds 13 mm, air is entrapped at the time of refilling and bubbles are generated in the container of the transfer destination, and the bubbles overflow from the outlet of the container, As a result, the entire amount of the liquid to be injected cannot be filled. In addition, the above-mentioned dent portion necessary for forming the above-mentioned communication space 7 can be formed by heating and stretching the sheet forming the side surface portions 2, 2. In some cases, inconvenience such as cracking of the sheet occurs during stretching. In addition, from the viewpoint of further preventing these inconveniences, the inner diameter W of the above-described pouring cylinder 6 is particularly preferable.
Is 8 to 11 mm.

The content of the surfactant is 0.1
%, It is difficult to adjust the viscosity of the liquid composition to 15 cp or more, while if it exceeds 70%, it becomes difficult to adjust the viscosity of the composition to 1000 cp or less.
From the viewpoint of further preventing such inconveniences, a particularly preferred content of the surfactant is 5% to 50%.

In the standing pouch 1 of the present embodiment, the total length and outer diameter of the pouring cylinder 6, the total length of the communication space 7, the length and width of the protruding portion of the take-out portion, and [preferable values] thereof are shown. It is as follows. In addition, the numerical value described first in each of the following items is the numerical value in the standing pouch 1 of the present embodiment. -Total length of the pouring cylinder: 18 mm [10 to 30 mm, especially 15 to 25 mm]. -Outer diameter L1 of the pouring cylinder (see FIG. 3); 11 mm [9 to
16 mm, especially 9 to 13 mm].・ Total length L2 of communication space (see FIG. 2);
60 mm, especially 30 to 50 mm]. -Length L3 of the protruding portion of the take-out portion (see FIG. 2); 28 mm
[20-60 mm, especially 20-40 mm]. -Width L4 of the protruding portion of the take-out portion (see FIG. 3); 18 mm
[16 to 26 mm, especially 16 to 23 mm].

The material of the sheet (film) used for the bottom portion and both side portions is not particularly limited, but when the standing pouch of the present invention is used as a refill container for refilling, the refill is used. Conventional materials, such as LDPE, stretched nylon (ONY), or PET, which are conventionally used as a material for the container, can be used. The sheet may be a single-layer sheet or a laminated sheet.
A laminated sheet having at least one LLDPE film of 00 μm is preferred. When such a laminated sheet is used, the spout of the above-described embodiment can be easily formed. In addition, the shape of the standing pouch is stabilized during the pouring operation, so that the refilling operation becomes easier. Also, as the method of joining the sheets, various conventionally known methods such as heat welding can be used. Further, as a liquid composition containing a surfactant at a specific content to be filled in the standing pouch of the present invention and having a specific viscosity, dishwashing detergent,
Residential detergents, clothing detergents and the like can be mentioned.

When taking out the contents from the standing pouch 1 of the present embodiment, first, the tip of the take-out section, where the pouring cylinder 6 is not located, is cut off. In the standing pouch according to the present embodiment, the take-out cylindrical body 6 is provided at the take-out portion 5, so that the communication space 7 is not crushed even if the take-out portion 5 is pinched during cutting. Since the cutout forms a spout for the contents in the take-out section 5, the liquid composition inside can be discharged from the spout in the same manner as in a conventional standing pouch and transferred to another container.

In the standing pouch 1 of the present embodiment, since the spout is formed so as to protrude from the tip of the take-out portion 5, the spout is inserted from the mouth of the transfer destination container into the inside. Since the contents can be injected, the risk of the contents leaking to the outside when the contents are transferred is further prevented. In the standing pouch according to the present embodiment, the liquid composition is poured out through the inside of the pouring cylinder 6, so that the pouring path is deformed and the outflow speed is rapidly reduced. Or increase is prevented.

The liquid composition contains 0.1% to 50% of a surfactant and has a viscosity (20 ° C.) of 15%.
cp to 1000 cp, and the inner diameter W of the pouring cylinder 6 provided in the take-out section 5 is 8 mm to 13 mm.
From the start to the end of the transfer, the dispensing speed becomes very stable, and almost no splashing or bubbles are generated. Therefore, the contents can be easily, promptly and reliably transferred into the container to be refilled, regardless of the diameter of the transfer destination container.

The standing pouch according to the present invention is not limited to the above-described embodiment, and its dimensions and shape can be appropriately changed without departing from the object of the present invention.

In the case of, quick refilling was possible without generation of bubbles. On the other hand, in the case of the comparative example, it can be seen that bubbles are generated and it takes a long time to pour out, and thus it is not suitable as a refill container for refilling. In addition, as shown in Table 2, in the evaluation of workability, in the example (inner diameter of the pouring cylinder 9 m)
m or 11 mm), the refilling operation was easy, the refilling time was not troublesome, and the refilling workability was excellent. On the other hand, the inner diameter of the pouring cylinder is 7.5 m.
In Comparative Examples of m or less, many people were worried about dripping or running out of the liquid, resulting in poor workability. In the comparative example having an inner diameter of 15 mm, foaming increased, which was similarly unfavorable.
