DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bag-shaped flexible package (pouch) filled with a powdery or liquid content, and more particularly to a content filling effective for refilling the content into another container. For standing pouches.

[0002]

2. Description of the Related Art Various types of bag-like flexible packages (pouches) used for refilling contents such as liquid detergents, softeners, liquid soaps, etc. are provided on the market. Among them, Japanese Patent Application Laid-Open No. H11-1000049 discloses a technique for improving the ease of pouring when refilling a standing pouch.
There is a number.

[0003] In this method, an oblique cut portion is formed at one upper corner of the pouch, and a point on the cut portion is connected to a point on the other side of the pouch via a storage portion. Is formed from one point on the downward inclined line. In this manner, the contents are refilled by inserting the spout into the mouth of the bottle to be refilled in a state in which the vicinity of the spout is formed in a tapered shape by bending along the expected bending line.

[0004] In this case, since the vicinity of the spout can be formed into a tapered shape by bending at the expected bending line, the spout can be inserted deeply into the mouth of the bottle to be refilled. It is described that the outlet can be prevented from coming off.

[0005]

However, in the above-described technique, since the content is filled up to an upper portion beyond the expected bending line because the method is to bend at the expected bending line, when the content is filled, There is a high possibility that the internal air will be pushed and the contents will flow out of the spout. For this reason, it is necessary to make the filling state such that the upper surface level of the contents comes to a level lower than the expected bending line, and the upper part of the pouch becomes flat because the contents are not filled in the upper part of the pouch. For this reason, it appears that the contents are less than the size of the pouch in appearance of the product.

Further, in the above-mentioned invention, as shown in the drawing, when the sheet is bent along the predetermined bending line, the spout formed by cutting the predetermined cutting portion is in a crushing direction, which is not preferable in discharging the contents. As described in the above-mentioned invention technology, when the content has a high viscosity, it is necessary to squeeze out the pouch to squeeze it out, and it is presumed that it is difficult to obtain a good pour with one hand operation. .

[0007] In view of the above, the present invention provides a standing pouch for filling contents, which can obtain good pouring by one-handed operation. It is another object of the present invention to provide a standing pouch for filling contents, which exhibits a new three-dimensional appearance in terms of design.

[0008]

According to the present invention, in order to solve the above-mentioned problems, the front surface material, the back surface material and the bottom surface material are formed of a plastic film or sheet, and the joint between the front surface material and the back surface material is provided. In a standing pouch in which a lower end portion of a front surface material and a lower surface material and a joining portion of the bottom surface material are sealed to form a content filling storage portion in which a bottom portion is spread back and forth between the front and back surface materials, one of the top portions of the pouch upper portion A pour portion for discharging the content is provided at a corner of the pouch, and a pouch side portion on the side of the pour portion is directed from the left and right side portions of the pouch to the pour portion in the content-filled state. A constricted portion that forms a bent ridge portion is formed to improve the formation of the opening of the pouring portion.

Further, the present invention is also directed to the present invention, wherein the front surface material, the back surface material, and the bottom surface material are made of a plastic film or sheet, and the joint between the front surface material and the back material, the lower end of the surface material and the back material, and the bottom material. In a standing pouch in which a sealing portion is sealed to form a storage portion for filling contents which is spread back and forth between the front and back surfaces, a pouring portion for discharging the contents is provided at one corner of an upper portion of the pouch. In the content-filled state, a rising portion that is steeper than the lower portion of the pouch and a ridge portion that gradually decreases from the rising portion toward the pouring portion are formed on the left and right side portions of the pouch. A constricted portion is provided.

[0010] In the present invention, the sealing portion on the upper portion of the pouch opposite to the pouring portion side of the sealing portion may include:
By forming the pouch on an oblique line extending from the upper side to the side side, the pouch has a feature that the bulging portion and the ridge portion can be formed considerably high.

Further, the present invention seals a joint between the front material and the back material and a joint between the lower end of the front material and the back material and the bottom material so that a bottom portion extends forward and backward between the front and back surfaces. A storage portion for filling the contents, a cuttable portion extending obliquely downward from the upper side to the side side at one corner of the upper portion, and a constricted portion formed on the left and right side sides to fill the storage portion with the contents. Prepared standing pouch, after cutting the severable portion to form a spout for the content pouring,
It is an object of the present invention to provide a characteristic pouring method capable of satisfactorily pouring contents from the pouring section while holding the constricted section with one hand.

4 is an explanatory view of a state in which the standing pouch is grasped, FIG. 5 is an explanatory view of a state in which the standing pouch is grasped and poured out into a bottle, and FIG. 6 is a front view of a standing pouch of another embodiment. FIG. 7 is a front view of a standing pouch according to another embodiment,
FIG. 8 is a front view showing the dimensions of the pouch of FIG.

First, the standing pouch of the embodiment shown in FIGS. 1 to 5 will be described. The pouch of the present invention
Liquid or powder contents to be filled therein include liquid detergents, softeners, liquid soaps, etc., and bag-like flexible packaging for storing the contents in containers such as other bottles for refilling. It is a body (pouch) and is a so-called standing pouch that can be placed upright on a table or the like with the bottom part down. In this standing pouch 1, the front material 2, the back material 3, and the bottom material 4 are made of a transparent material, an opaque material,
Any translucent material may be used, and it is composed of a plastic film or sheet. The film or sheet has, for example, a three-layer structure in which the outer layer is a biaxially stretched nylon film, the intermediate layer is a uniaxially stretched polyolefin film, and the inner layer is a linear low-density polyolefin. Surface material 2
A joint 5 between the front and back members 3 and a joint 6 between the lower end of the front and rear members 3 and the bottom member 4 are heat-sealed, respectively. The contents-filling storage portion 7 extending back and forth is formed inside the standing pouch 1. The outer layer may be transparent, the intermediate layer may be a pouch having a silver color or the like as a barrier film provided with an inorganic compound vapor deposited layer by vapor deposition of aluminum or another inorganic compound by a method such as a vacuum vapor deposition method. .

The standing pouch 1 is provided at one upper corner with a cutout portion 10 formed by a cutable portion 10 extending obliquely downward from the upper side 8 to the side 9 of the pouch 1. 11 are provided. This severable portion 10 may be formed so as to be cut with scissors,
A notch or a notch is provided at the end of the severable portion 10 so that the corner can be cut by hand.
A scratch process such as a laser process or a perforation process can be performed on the 0 in advance. The location of the severable portion 10 is indicated by a method such as printing on the front surface material 2 or the back surface material 3 or indicating by a notch formed on the upper side 8 or the side side 9.

When the contents are filled, the standing pouch 1 is formed on the side 9 on the side of the pouring section 11 by a cuttable portion 10 from between the left and right sides 9 of the pouch 1 when the contents are filled. A constricted portion 13 is provided, which forms a ridgeline portion 12 facing the pouring portion 11 to be discharged.

In particular, the constriction 13 on the side 9 on the side of the pouring section 11 forms a ridge 12 toward the pouring section 11, whereby the front surface material 2 and the back surface material 3 mutually spread in the front-back direction. In the state in which the cuttable portion 10 is cut, the formation of the discharge passage for the contents toward the discharge portion 11 along the ridgeline portion 12 becomes good, and the opening of the discharge portion 11 is opened or easily opened. . For this reason, when the pouring unit 11 is aligned with the mouth of another container 14 such as a bottle, the contents smoothly flow out of the opening of the pouring unit 11 and enter the other container 14 such as a bottle. When the contents are transferred to another container 14 such as a bottle as described later, the ridge 12 is further conspicuous when the constricted portion 13 is grasped with one hand, so that the pouring portion 11 is further opened or easily opened. Objects can be poured smoothly. As shown in FIGS. 4 and 5, the constricted portion 13 is also a portion useful for performing the operation of discharging the contents with one hand.

The ridge 12 and the constriction 13 will be described in more detail. The standing pouch 1 shown in FIG. 1 has a rising portion 20 having a steeper slope than the lower portion near the bottom of the pouch 1 in a filled state, and a ridge portion 12 gradually lowering from the rising portion 20 toward the pouring portion 10. Are formed on the left and right side portions of the pouch 1. The constricted portion 13 is formed so as to correspond to the left side 9 and the right side 9 back to back, and the left and right sides of the pouch 1 are constricted. As a result, the pouch 1 filled with the contents and heat-sealed around the periphery thereof has a size such that the bottom material 4 is stretched at the bottom, as shown in FIGS. Figure 2
As shown in FIG. 5, the width of the pouch 1 extends to the middle portion 21 of the pouch 1 near the constricted portion 13 while the width on the left and right is reduced by the constricted portion 13, and gradually widens from the constricted portion 13 toward the upper side 8. It has a shape converging on.

In the conventional vertically rectangular pouch having no constricted portion 13, the lower part of the pouch gradually narrows toward the upper part of the pouch. Constricted part 13 of part 21
, And the constricted portion 13 works effectively to keep the pouch bulge at a higher position than the conventional one.

As described above, the standing pouch 1 shown in FIG. 1 has the ridges 12 and another ridge 15 formed by the constrictions 13 provided on both the left and right sides.
Thereby, as shown in FIG. 4 and FIG.
When the contents are ejected with one hand, the swelling of the front surface material 2 and the back surface material 3 in the upper part of the pouch 1 in the front-rear direction can be increased.

In the standing pouch 1 shown in FIG. 1, the seal 16 at the upper corner of the seal 5 opposite to the pouring section 11 is applied from the upper side 8 to the side 9 of the pouch 1. It is formed on an oblique line. As a result, the length of the other ridge portion 15 becomes shorter than the length of the ridge portion 12, and when the contents are to be poured out with the constricted portion 13 with one hand, the spout portions 11 along the ridge line portion 12. There is an effect that the movement of the contents toward the outlet is improved, and the spread of the opening of the pouring section 11 can be further improved.

FIG. 8 shows an example of the external dimensions of the pouch 1 of the present invention.
Shown in FIG. 8 shows dimensions of the pouch 1 before filling the contents in a front view, and the unit of the number is mm (millimeter). The inner volume is 400 ml (milliliter) of tap water.

FIG. 6 shows a standing pouch 1 according to another embodiment. The difference from the standing pouch 1 in FIG. 1 is that the constricted portion 13 is formed only on the pouring portion 11 side and the seal portion 16 on the oblique line at the upper corner opposite to the pouring portion 11 side. It is a point that has not been formed. In this case, the swelling in the front-rear direction of the front surface material 2 and the back surface material 3 at the upper part of the pouch 1 is smaller than that of the standing pouch 1 of FIG. The effect of opening or easy opening can be sufficiently exhibited.

FIG. 7 shows a standing pouch 1 of still another embodiment. The difference from the standing pouch 1 in FIG. 1 is that the sealing portion 16 on the oblique line at the upper corner opposite to the pouring portion 11 is not formed. In this case, there is no effect of the seal portion 16 on the oblique line, but the swelling of the front surface material 2 and the back surface material 3 in the front-back direction at the upper part of the pouch 1 is better than that of the standing pouch 1 of FIG. The effect of opening or facilitating the opening of the pouring section 11 due to the presence of the ridge 12 is sufficient.

As described above, the constricted portion 13 provided on the side 9 of the standing pouch 1 of the present invention is formed at least on the side 9 on the side of the pouring section 11, and the pouch 1 is filled with the contents. Pour out part 1 between the right and left sides 9, 9
1 is formed, and has the effect of improving the formation of the opening of the pouring section 11. For this reason, the constricted portion 13 may be formed back to back on the left and right sides 9 and 9 of the pouch 1 as shown in FIGS. 1 and 7, and as shown in FIG. It may be formed only on the side 9.

As the constricted portion 13 is formed deeper, the rising slope 2 from the constricted portion 13 to the ridgeline portion 12 becomes steeper, and the ridgeline portion 12 tends to be angular. However, if the depth is too deep, the constricted portion 13 acts as a barrier when the contents in the pouch 1 are poured out, and it becomes difficult to pour out the contents in the pouch 1 below. The depth, size, and position of the constricted portion 13 may be set in consideration of the relationship with the condition. Also,
Since the constricted portion 13 is also effective as a finger hook when the content is poured out, it is convenient for one-handed pouring.

In particular, the constricted portion 13 on the side 9 on the side of the pouring section 11 forms a ridge 12 toward the pouring section 11, whereby the front surface material 2 and the back surface material 3 spread in the front-rear direction. When the cutable portion 10 is cut, the opening of the pouring portion 11 is opened or easily opened. For this reason, when the pouring section 11 is fitted to the mouth of another container 14 such as a bottle, the contents can smoothly flow out of the opening of the pouring section 11 and be transferred into another container 14 such as a bottle. . In addition to the form formed by the cutable portion 10, the pouring portion 11 may be a method of peeling off the seal of the front surface material and the back surface material at the corner of the pouch 1.

The present invention is not limited to the above-described embodiment, and various modifications are conceivable without departing from the technical scope of the present invention, and include various embodiments according to the present invention.

[0028]

According to the first aspect of the present invention, the ridge line toward the pouring portion is formed by the narrow portion on the side of the pouring portion,
As a result, the front surface material and the back surface material mutually spread in the front-rear direction, and the formation of the content discharge passage toward the discharge portion along the ridge line portion is improved, and the opening of the discharge portion is opened or easily opened. Become. For this reason, it is easy to transfer the contents into another container such as a bottle by aligning the pouring section with the mouth of another container such as a bottle.

According to the second aspect of the present invention, the left and right sides of the pouch have rising portions that are steeper than the lower portion of the pouch when the contents are filled, and gradually lower from the rising portions toward the discharging portion. Is formed. For this reason, the expansion of the lower part of the pouch extends to the constriction in the middle part of the pouch, and the constriction acts more effectively to keep the pouch bulging to a higher position than in the conventional pouch, and the width of the constriction is reduced. It is effective to cover the decrease with the thickness and to present a thick product appearance.

According to the third aspect of the present invention, the seal portion of the upper part of the pouch opposite to the side of the spouting portion of the seal portion is formed on an oblique line extending from the upper side to the side side of the pouch. The length of the ridge line toward the spouting section is longer than the length of the other ridgeline section. Is further improved.

According to the fourth aspect of the present invention, when the constricted portion is gripped with one hand, the ridge portion is further conspicuous, so that the spread of the opening of the pouring portion can be improved, and the contents move along the ridge line portion during pouring. And the contents can be smoothly poured out. For this reason, the pouch of the present invention has an effect suitable for a one-hand pouring operation.
