DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bag for holding a liquid or a granular material as a content, and more particularly to a bag for refilling the content in another container.

[0002]

2. Description of the Related Art Bag-shaped containers (hereinafter referred to as pouch containers) have been known as containers for refilling liquid or powdery contents such as detergents for clothes, detergents for dishes, and softeners for clothes. In general, a seal type (joining portion) provided at an upper end of a container sealed in a bag shape is cut horizontally, and contents are poured out from an outlet formed in a central portion.

However, when refilling high-viscosity liquids such as shampoos, rinses, treatments, and whole body cleansing agents, it is necessary to shorten the refilling time and to squeeze out the pouch containers in order to completely discharge the liquid contents. However, pouch containers of the type described above have disadvantages such as spillage of liquids and time required for refilling. The same was true for the powder and granules.

On the other hand, in order to facilitate the refilling operation, a refillable pouch container having an outlet which can be inserted into an inlet of a receiving container into which a liquid is transferred is disclosed in Japanese Patent Laid-Open No.
Japanese Patent Publication No. 285562 discloses a liquid pouch container in which a non-joining projection is provided at an upper joining portion of a liquid pouch container, and a hole or a cut is provided at a position spaced apart from a side edge thereof.

[0005] Further, in the apparatus described in Japanese Utility Model Application Laid-Open No. 57-85436, a protruding portion for cutting off the tip to form an outlet is provided at a side joint of a substantially cylindrical liquid pouch container. Are disclosed. Japanese Patent Application Laid-Open No. 7-2260 discloses a pouch container in which a spout is provided at one corner of a bag along an outer shell.

[0006]

SUMMARY OF THE INVENTION
In what is described in JP-A-7-285562, in order to form an outlet that can be inserted into the inlet of the receiving container, it is necessary to cut off the upper end joint of the pouch container from one end to the other end, and a hole in the middle. Alternatively, since the cut is provided, the upper end joint cannot be removed by one operation, and there is a problem that the operation is complicated. In addition, there is a problem that it is difficult to insert the outlet into the inlet of the receiving container because a joint having an upper end substantially at the same height as the outlet remains near the formed outlet.

[0007] Further, in Japanese Utility Model Application Laid-Open No. 57-85436, since a protruding portion is formed at the side joint of the pouch container, the protruding portion is turned upward so that the contents do not protrude. When the outlet is to be formed, there is a problem that the cylindrical side surface of the pouch container is turned down and cannot be stably held. In addition, there is a problem that it is difficult to insert the outlet into the inlet of the receiving container without spilling the contents when inserting the outlet into the inlet, which is not practical.

Further, in the device described in Japanese Patent Application Laid-Open No. 7-2260, since the discharge nozzle is formed by cutting out the corner of the upper edge of the pouch container, the contents easily accumulate near the notch. In addition, there is a problem that the contents are likely to remain in the squeezing operation of the contents. More specifically, the content tends to remain at the intersection of the upper edge and the notch. SUMMARY OF THE INVENTION In view of such conventional problems, an object of the present invention is to provide a bag capable of smoothly discharging the contents of a liquid or a granular material without leaving it, and easily transferring the contents to another container.

[0009]

Therefore, in the invention according to the first aspect, a high-viscosity liquid or granular material is formed by joining both side surfaces and a bottom surface made of a soft film-like member to form a seal. In a pouch-shaped bag that holds the contents of the bag, the bag includes a portion that holds the contents, and a nozzle portion that is formed with an outlet that discharges the contents by cutting a tip portion, and the nozzle parts, the than the upper edge from a end of the upper edge of the portion holding the contents protrude upward, the inner surface and outer surface of the nozzle portion together,

[0013]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view showing one embodiment of the pouch container of the present invention. As shown in FIG. 1 (a), the pouch container 1, the side surface portions 2a of the substantially rectangular film member or Ranaru Vertical soft, and side portions 2b provided on the side surface portions 2a and symmetrical bottom portion 3 and is formed in a sealed shape with a bottomed bag, and the two side portions 2a and 2b are
a, 4a and the upper edge 4b are joined at a high viscosity
Ku holds the contents of the granular material, the end portion of the <br/> upper edge 4b of the portion that holds the contents, the nozzle portion 5 of the tapered on the inner outside both are projected. Then, as shown in FIG. 1B, an outlet 6 for discharging the contents is formed by cutting the tip 5a of the nozzle portion 5.
An edge is formed by the two side edges 4a, 4a and the upper edge 4b.

After forming the outlet 6, the pouch container 1 tilts the entire pouch container 1 and, through the nozzle section 5, transfers the contents such as liquid or powder from the outlet 6 to a receiving container such as a cup or a bottle. Used for discharging and refilling. Since the nozzle portion 5 is formed in a tapered shape by protruding from the upper edge portion 4b, the tip portion 5a can be cut off by one operation, and the outlet 6 for discharging the contents can be easily formed. Further, even if the receiving container for transferring the contents discharged from the pouch container 1 is a bottle having a small entrance, the tapered nozzle portion 5 can be easily inserted into the entrance of the receiving container. The refilling operation can be performed quickly without spilling.

Also, at the time of squeezing work, the pouch container 1
Is performed. However, since the nozzle portion is provided so as to protrude, the side portions 2a and 2b do not interfere with the outlet 6 formed at the tip of the nozzle portion 5, and the squeezing operation is easily performed. be able to. In particular, as shown in FIG. 2, the shape of the nozzle portion 5 in the symmetrical vertical section A that symmetrically bisects the sheet-like pouch container 1 including the edge portion 4 and containing no contents is 20 ° to 70 °. ° taper angle α
The nozzle portion 5
By tilting the pouch container 1 so that the contents flow toward the outlet, the outlet 6 naturally opens due to the pressure of the contents, and the flowability of the contents is improved. Thereby, the contents are easily discharged, and the contents can be easily squeezed out. In this regard, a more preferable range of the taper angle α is 30 ° to 60 °.

On the other hand, if the taper angle α is smaller than 20 °, the outlet 6 becomes difficult to open due to the pressure of the contents, and the discharge becomes difficult. When the taper angle α is larger than 70 °, it becomes difficult to insert the nozzle portion 5 into the inlet of the receiving container.
In the case where the nozzle portion 5 has a tapered shape having a curved line, the taper angle α is, as shown in FIG. 5, a line drawn in parallel with the base 8 in FIG. The two lines L ', drawn so as to be in contact with the line inside the nozzle at the portions 7a and 7b where the line inside the
L ”is the angle of intersection. By drawing the bisector, β and γ are determined.

If there is no notch, a line parallel to the bottom 8 is drawn at a position (measured at the inner edge) of 80% of the discharge length upward from the upper edge 4b of the nozzle portion. Similarly, α, β, and γ are determined. The angle β between the reference line L orthogonal to the pouch bottom 8 and the bisector of the taper angle is 10
If the nozzle portion 5 having the outlet 6 is formed so as to be inclined so as to have an angle β of 60 ° to 60 °, it is possible to insert the nozzle portion 5 into the inlet of the receiving container without spilling the contents. If the angle β is a value within the above-described range, for example, as shown in FIG. 3, the nozzle portion 5 may have a shape protruding sideways from the edge portion 4.

On the other hand, if the angle β is smaller than 10 °,
When the nozzle portion 5 is inserted into the entrance of the receiving container, the contents are easily spilled. When the angle β is larger than 60 °, when the nozzle portion 5 is inserted into the inlet of the receiving container,
The pouch container 1 does not become inverted, and it becomes difficult to discharge the contents. Furthermore, if the outlet 6 forms an angle γ of 30 ° to 80 ° with the bisector M of the nozzle part 5 and cuts the tip part 5a at a cutting plane B orthogonal to the symmetric longitudinal section A, The outlet 6 has a sharp pointed shape, and the nozzle portion 5 can be inserted into the inlet of the receiving container without spilling the contents.

On the other hand, if the angle γ is smaller than 30 °,
When the nozzle portion 5 is inserted into the entrance of the receiving container, the contents are easily spilled. If the angle γ is larger than 80 °, the length of the nozzle portion 5 inserted into the entrance of the receiving container becomes short, and it becomes difficult to squeeze out the contents from the pouch container 1. If the length n of the line of intersection between the symmetrical longitudinal section A and the cut plane B is shorter than the inner diameter of the inlet of the receiving container into which the contents are injected from the pouch container 1, the nozzle portion 5 Insertion becomes easier. In order to easily discharge the contents, it is necessary to make the cut surface B as large as possible, and to make it easy to insert the nozzle portion 5 into the inlet of the receiving container, it is necessary to reduce the length n of the intersection line. . For this reason, the width of the joining portion 5b at the outer edge of the nozzle portion 5 may be formed to be narrower than the width w of the edge portion 4 where the side portions 2a and 2b are joined, as far as the strength is allowed. In addition, as for the length n of the intersection line, if the length of the cut surface of the nozzle in the closed state is shorter than the inner diameter of the entrance of the receiving container, the insertion becomes extremely easy, but the nozzle in the open state is extremely easy. If the length of the cut surface is shorter than the inner diameter of the entrance of the receiving container, it can be inserted.

Further, as shown in FIG.
If the notch 7 is provided at the joining portion 5b, which is the outer edge of the nozzle portion 5, as a cutting guide portion that facilitates cutting the tip portion 5a at a predetermined surface, the outlet 6 can be easily formed at the cutting surface B described above. Can be formed. As a cutting guide portion, in addition to the above-described notch 7, only the cutting at the cutting surface B is facilitated.
The tip 5a of the nozzle 5 may be formed of an anisotropic material such as axially-stretched polypropylene. Also, cut surface B
A laser cut along the line, that is, a film material of the pouch container is made of laminated materials with different laser absorptivity. May be provided by providing a slit-shaped cut groove. Alternatively, a line along the cut surface B may be printed on the nozzle 5, and the tip 5a may be cut along the line with scissors or the like.

When the contents are liquid, the above-mentioned pouch container 1 can be easily discharged as long as it has a viscosity of 200 cp to 100000 cp, and all the contents can be transferred to the receiving container without waste. . The liquid viscosity of the contents is 200
If it is lower than cp, the liquid tends to drips from the outer edge near the outlet 6 of the nozzle portion 5, and the surroundings may be soiled. Also,
When the viscosity exceeds 100,000 cp, it becomes difficult to discharge the liquid from the pouch container 1 smoothly.

The contents of the pouch container 1 include:
It is not limited to a liquid, but may be a powder. As a material forming each part of the pouch container 1, a soft resin film-shaped member,
In particular, a film-like member in which a plurality of resin layers and metal layers are laminated is preferably used. Although the material to be laminated is not particularly limited, for example, stretched nylon (ONy), stretched polypropylene (OP) having excellent mechanical strength and moisture resistance
P), aluminum (Al), and linear low-density polyethylene (LLDPE) laminated in order.
It can be used such that the Ny layer is located outside the pouch container 1.

Further, the entire pouch container 1 can be formed by one film-shaped member, but may be formed by combining a plurality of film-shaped members. For example, the side portion 2a and the side portion 2a side portion of the nozzle portion 5 are formed of one film member, and similarly, the side portion 2b and the side portion 2b side portion of the nozzle portion 5 are formed of another film member. Bottom part 3
May be formed with another film member, and these three film members may be integrally joined to form the pouch container 1.

If the whole is formed of one film-like member, the management of the material and the like become easy, and the production can be performed at low cost. On the other hand, if a plurality of film-shaped members are used, pouch containers of various designs can be easily formed. In order to confirm the effect of the liquid pouch container of the present invention, the pouch container 1 having the same configuration as that of the above-described example using three film-shaped members is provided on the side portions 2a and 2b and the nozzle portion 5, From the outside, each thickness is ONy: 15 μm,
OPP: 25 μm, Al: 7 μm, and LLDPE:
100 μm, and a film-like member in which 100 μm are sequentially laminated, and the bottom portion 3 is similarly formed with ONy: 15 μm and Al: 7 μm.
m and LLDPE: 100 μm, in that order.

FIG. 5 shows a specific shape. In the pouch container 1, the angle α is 45 °, the angle β is 30 °, and the angle γ
Was set to 60 °, and a notch 7 was provided as a cutting guidance portion at a joining portion, which is the outer edge of the nozzle portion 5. This pouch container 1
Then, a hair rinse having a viscosity of 8000 cp was filled as a content and sealed, and then the tip 5a of the nozzle portion 5 was cut off by hand using a notch 7 to form an outlet 6. Then, when the nozzle portion 5 was inserted into the inlet of the bottle, which is a receiving container having an inner diameter of 24 mm, and the rinse of the contents was transferred, the contents could be easily transferred without spilling.

As can be seen from FIG. 5, the transfer of the liquid can be made smoother by providing an appropriate radius at the corner.
