Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a standing pouch for refilling, the ease of pouring during refilling being improved.

[0002]

2. Description of the Related Art Standing pouches used for refilling are intended for relatively low-viscosity contents such as kitchen detergents and relatively high-viscosity contents such as liquid soaps such as body soaps. Widely used.
In this standing pouch, it is an important issue how to add a function of the ease of pouring at the time of refilling. A normal standing pouch has an opening (cutting) line extending obliquely from the side to the upper side at one upper corner thereof as a pouring structure, and is cut along the opening line. Thus, a configuration in which a pouring portion is formed at a corner is adopted. This configuration is effective in that a normal standing pouch form can be used as it is, the spouting portion can be formed in a tapered shape, and the standing pouch can be poured only by being tilted while being held by hand.

However, when viewed as a standing pouch for refilling, its pouring structure was not sufficient. That is, in the case of a standing pouch for refilling, the body container to be refilled is generally a bottle, and must be poured into a mouth having a small diameter of about 1 to 2 cm. In this case, in many cases, the above-mentioned standing pouch pouring structure cannot be poured well.

[0004] That is, if the pouring outlet of the standing pouch is poured away from the mouth of the bottle, the hand may not be fixed and may be spilled. In addition, there are two problems when pouring the standing pouch into the mouth of the bottle when pouring it out. One is that the spout is provided at the corner of the standing pouch. However, since the corner of the normal standing pouch is almost right angle, even if the spout is inserted into the mouth of the bottle, the length to enter is short, There was a sufficient risk that it would come off during the unloading operation. In particular, when the contents are of high viscosity, this phenomenon is likely to occur because an operation of squeezing out the standing pouch is performed.

[0005] The second problem is that since the sealing portions are provided above and below the spout of the standing pouch, the length of the spout is set to be shorter by the length of the upper and lower sealing portions with respect to the mouth of the bottle. Must. As a result, the pouring amount of the standing pouch itself is regulated.

In order to solve these problems, the upper side of the standing pouch is formed in a tapered shape, and the corner forming the spout is formed into an acute angle, thereby facilitating the operation of inserting the spout into the mouth of the bottle. Is disclosed. However, this configuration has various problems because the standing pouch itself has an irregular shape. That is, when manufacturing a standing pouch, a special apparatus is required or the number of steps has to be increased. Also, when filling and sealing the contents, a special device is similarly required.

[0007] Also, when the user pours out, in this configuration, since the upper and lower seal portions of the spout still remain, the length of the spout is not different from that before the improvement. As a result, the pouring amount is still restricted by the length of the pouring outlet, and a satisfactory pouring operation cannot be performed.

[0008]

SUMMARY OF THE INVENTION As described above, the present invention relates to a standing pouch having a heat-sealable front and back film in which the upper and lower sides and both sides are sealed and provided with a storage portion surrounded by the seal portion. This type of standing pouch, which is usually widely used, is used in a form that does not greatly change, and when the user pours out the contents, the user can perform a special but very simple operation, It is an object to significantly improve the ease of pouring.

[0009]

According to the first aspect of the present invention,
A spout forming tubular portion which is biased to one of the left and right sides of the standing pouch and communicated with the storing portion is formed on the upper portion of the storing portion so as to rise upward, and the diameter of the spout forming tubular portion is increased. The dimensions are set to be the same as or shorter than the inner diameter of the mouth of the main container of the refill destination, and a horizontal uniaxially stretched film is adopted as the front and back films, and at least one surface of the front and back films is A horizontal straight cut line along the upper side that traverses the middle of the vertical length of the spout forming tubular portion, and a point on the planned cut line and the side where the spout forming tubular portion is provided. And a predetermined bending line extending in a downwardly inclined shape by connecting one point on the side on the side opposite to.

According to this means, along the cutting line,
By cutting the lower part of the upper side of the standing pouch in the horizontal direction, the front and back films are formed of a horizontal uniaxially stretched film, so that the film can be easily cut in parallel with the upper side into a single horizontal character. As a result, tearing can be easily performed with bare hands without using a cutting tool such as scissors or a cutter as in the related art.

[0011] Further, according to the present invention, a spout forming tubular portion communicated with the storage portion is formed on the upper portion of the storage portion so as to be deviated to one of right and left sides of the standing pouch, and The diameter of the spout forming cylinder is set to be the same as or shorter than the inner diameter of the mouth of the main container to be refilled. As a result, as described above, even if the standing pouch is cut, at least within the range of the vertical dimension of the spout forming tubular portion, wherever it is cut, the spout obtained thereby is The opening is formed as the same size as or shorter than the inner diameter of the mouth of the main body container to be replaced. In other words, the caliber as set in advance can be easily obtained simply by cutting the standing pouch.

[0012] Further, by bending the bent portion above the expected bending line through the expected bending line to either the front or the rear of the standing pouch, the vicinity of the spout becomes a tip of the spout. Can be tapered. Therefore, while holding this folded state by hand, if the standing pouch is tilted and the spout is inserted into the mouth of a bottle or the like, which is the main body container to be refilled, it is extremely easy to put this spout into the mouth of the main body container I can insert it. Further, as described above, the opening diameter of the spout of the standing pouch is constant regardless of which part of the spout forming cylinder is cut off. Therefore, unlike the conventional case, there is no need to pay attention to the cutting position, and the ease of insertion into the mouth of the main container to be refilled can always be ideally achieved.

Therefore, the present invention has the following effects.
While taking the form of a normal standing pouch, it greatly improves its pouring out. That is, it can be configured by providing a spout forming cylinder and a line to be bent in the form of a normal standing pouch. As a result, in the manufacturing, filling, and sealing steps of the standing pouch, almost the same apparatus as that of a normal standing pouch can be used, and there is no inferiority in terms of the number of processing steps, cost, and the like to a normal standing pouch. Also, at the time of distribution and over-the-counter sales, no special consideration is required, and the same handling as conventional products is sufficient, and there is no inferiority in this respect.

In the standing pouch according to the present invention, the spout can be tapered with the spout at the tip thereof through the expected bending line. As a result, the spout can be easily and reliably inserted into the mouth of the bottle even in a small-diameter container such as a mouth such as a bottle which is a main container to be refilled. Therefore,
During the operation of pouring out the contents, the problem of the conventional structure in which the spout comes off the container carelessly can be solved well, and the refilling can be performed easily and securely.

In the present invention, the standing pouch can be cut open with a bare hand to open the spout. Therefore, there is no need to cut the standing pouch using scissors or a cutter as in the related art, so that the refilling operation becomes much simpler. In addition, the spout is opened with the same diameter no matter where it is cut. Therefore, it is not necessary to pay special attention to the cutting operation, and there is no possibility that the amount of the pour is restricted, and the refilling operation can be performed extremely easily, simply, and efficiently.

According to a second aspect of the present invention, the line to be bent is displayed as a solid line or a broken line by printing on the line,
For example, a ruled line processing is performed to enable recognition by an identification display that is visible to the user. As a result, in the refilling operation, the user can be made to strongly recognize the expected bending line. Therefore, the folding operation of this standing pouch in a tapered taper shape with the above-mentioned spout at the tip can be performed more accurately, and can greatly contribute to an increase in efficiency of the refilling operation.

According to a third aspect of the present invention, at least one of the surfaces of the front and back films is provided with a caution indicator for instructing that the corner of the standing pouch be bent through the predetermined bending line. As a result, the user can be more reliably informed of how to use the standing pouch of the present invention. Moreover, since this display is provided on the standing pouch itself, this warning display can be seen each time it is used, and in understanding how to use it, it can be easily and reliably deepened within a short time. Can greatly contribute to

[0018]

Embodiments of the present invention will be described below. FIG. 1 shows a standing pouch of the present invention. The standing pouch 1 is composed of front and back films 2 and 3 each having a substantially rectangular shape and a bottom film 4 folded in an inverted V shape. Sealing portions 9, 10 and 11 are provided on an upper side 5, a lower side 6, a left side 7 and a right side 8, respectively. , 12 and a storage unit 13 inside
Are formed.

The front and back films 2 and 3 slightly below the upper side 5 are provided with horizontal cut lines 14 and 15 connecting the left side 7 and the right side 8. The planned cutting lines 14 and 15 may be lines that do not have a supposed actual state. However, a printed display may be provided on the planned cutting lines 14 and 15 so that the user can clearly recognize the existence of the lines. it can. Further, in order to cut the planned cutting lines 14 and 15 without using scissors or the like, the left end of the planned cutting lines 14 and 15 is used as a trigger for opening the side end in the left seal 11. A notch 16 (a V-shaped notch in the illustrated example) is provided.

The notch 16 may be a cut line (I notch) instead of the V notch in the illustrated example.

Since the standing pouch of the present invention is cut open along the upper side 5 in the horizontal direction as described above, a material having a property of being more easily broken in the horizontal direction than in the vertical direction is employed. In order to facilitate the horizontal splitting, the front and back films 2 and 3 are made of a material suitable for this, that is, at least one horizontal uniaxially stretched film or a film whose horizontal stretching ratio is larger than the vertical stretching ratio. I have. Specific examples include stretched polyethylene terephthalate, stretched nylon, stretched polypropylene, and the like.

The standing pouch 1 of the present invention
It is needless to say that a heat-fusible plastic film is employed, but this plastic film may be employed in either a single layer or a laminate. In the case of a single layer, it is formed only of the stretched film, but is more preferably a laminated film. In this case, polyethylene, polypropylene, polyester, or the like is adopted as the innermost heat-sealable film.

In the standing pouch described above, according to the present invention, as shown in FIGS. 1 and 2, unlike the conventional one, near the upper left corner of the standing pouch 1,
The seal portion 9 of the upper side 5 is formed so as to be connected to the upper side 17 of the storage portion 13 and leave the spout forming cylinder portion 18 communicated with the internal space of the storage portion 13.
That is, the left side 19 of the spout forming tube portion 18 is formed so as to be on an extension of the innermost edge 20 of the seal portion 11 on the left side 7.

The diameter of the spout forming tube portion 18 is set to be substantially uniform from the communicating portion 21 with the upper side 17 of the storage portion 13 to the upper end side 22. The diameter L is set to be shorter than the inner diameter of the mouth of the bottle, or set to be equal at the longest. The planned cutting lines 14 and 15 extend in the middle of the vertical length of the spout forming tubular portion 18 rising integrally from the upper side 17 of the storage portion 13, that is, from the communication portion 21 to the upper end side 22. It is set so that it crosses the middle part just beside. The spout (described later) is exactly at the mouth of the bottle,
In addition, this is to ensure insertion.

Therefore, when the standing pouch 1 is cut right beside the cut lines 14 and 15 using the notch 16 as a trigger, as shown in FIG. 2, the vertical length of the spout forming cylinder 18 is increased. The midway is cut just beside, and after the cut, the spout 23 is opened.

Next, there are provided bent lines 24 and 25 inclined downward to the right connecting one point on the cut lines 14 and 15 and an arbitrary point on the right side 8 at the side end of the seal portion 12. I have. Through the bending lines 24 and 25,
A bent part 26 is formed on the upper part of the standing pouch 1.

Although the inclination angles of the predetermined bending lines 24 and 25 can be freely set, preferably, the sealing portion 11 on the left side is used.
Is preferably 45 to 60 degrees. Further, the planned cutting lines 14 and 1 of the planned bending lines 24 and 25 are used.
The one point set on the line 5 is the cut line 14, 1
5 can be set arbitrarily anywhere on the upper seal portion 9. However, in order to ideally achieve the intended technical problem of the present invention, it is preferable to set the position as close as possible to the right side 27 of the spout forming cylinder 18. More preferably, it is an intersection point between the scheduled cutting lines 14 and 15 and the right side 27 of the spout forming cylinder 18.

Further, the predetermined bending lines 24 and 25 are
Although it may be a line having no assumed actual state, an identification mark 28 is provided on the to-be-folded lines 24 and 25 so that the user can recognize the existence more. As the identification display 28, in addition to the display of a solid line or a broken line by printing, a visible display such as a ruled line processing is adopted.
In the case of performing the crease processing, it is preferable that the film on the side where the standing pouch is bent has a valley fold crease that is convex on the inner surface.

Another embodiment of the identification display 28 is shown in FIG.
Shown in As a specific configuration, the bending line 2
The entire surface of the bent portion 26 of the standing pouch having the lower sides 4 and 25 is printed in a design different from the rest of the standing pouch.

Further, as a variation of the present embodiment, it is possible to perform an arbitrary print display on the upper portion of the lower side of the predetermined bending lines 24 and 25. For example, a band-like display may be displayed, and a product name or a copy may be printed therein. Since the identification mark 28 is intended to allow the user to identify the to-be-folded lines 24 and 25, if this purpose can be achieved, the identification mark 28 is partially provided or overlaps with the identification mark 28. Product name,
A copy or the like can also be displayed.

The identification mark 28 can be provided on the front and back films 2 and 3 of the standing pouch, or can be provided only on one of the front and back films.

Further, there is provided a cautionary display 29 of characters and graphics for recognizing a user to bend and pour out the bent portion of the standing pouch via the predetermined bending lines 24 and 25. The warning indication 29 can be arbitrarily provided at any position on the front and back side films of the standing pouch.

Next, the operation of the above embodiment will be described. First, as shown in FIG. 4 (b), the upper side of the standing pouch 1 from the standing pouch 1 with the contents sealed before opening as shown in FIG. The part is cut straight from the notch 16 in the lateral direction. The standing pouch of the present invention
Since a material that is easy to cut in the horizontal direction is adopted,
Without using scissors or other instruments, they can be cut simply by hand. By this cutting, the spout forming tube portion 18 is cut up and down from the middle thereof, and a spout 23 is opened at the upper end of the remaining spout forming tube portion 18 on the side of the standing pouch 1 (FIG. 2). reference).

Next, as shown in FIG. 4 (c), a bent portion 26 above the expected bending lines 24, 25 is formed through the expected bending lines 24, 25 in front of the standing pouch 1, or It is bent to any one of the rear, and the vicinity of the spout 23 is formed into a tapered shape. This bending takes a curved shape on the expected bending lines 24 and 25 due to the rigidity of the front and back films. Further, both the front and back films can be squeezed and bent with a finger or the like on the bending lines 24 and 25. If the standing pouch 1 is to be strongly bent, it can be more easily achieved by applying a ruled line processing as the identification mark 28.

Further, as shown in FIG. 5, while holding the folded state by hand, the standing pouch 1 is tilted, and the spout 23 and the spout forming tube portion 18 continuing thereunder are tilted. It is inserted into the mouth 31 of the bottle 30 which is the container body of the refill destination. Then, the contents are poured into the bottle 30 to complete the refilling. Furthermore,
When the content has a high viscosity, the standing pouch 1 can be squeezed out in a squeezed manner.

The operation of inserting the standing pouch 1 into the mouth 31 of the bottle 30 is preferably performed quickly. In the present invention, the spout 23 of the standing pouch 1 is opened at the same time as the cutting is performed along the planned cutting lines 14 and 15. Therefore, as shown in FIG. 6, the bottle 30 is inverted and the standing pouch 1
It is desirable to insert the spout 23 into the mouth 31.

The diameter L of the spout 23 is, as described above,
The inner diameter of the mouth portion 31 of the bottle 30 is set to be shorter or equal, but is preferably set to be slightly shorter than the inner diameter of the mouth portion 31 of the bottle 30. The reason is that the spout 23 can be more easily inserted into the bottle mouth 31,
This is because the spout 23 can be inserted deeper into the bottle. This is because the spout 23 can be easily prevented from coming off the bottle during the refilling operation.

At this time, as seen in the conventional structure,
If the length of the spout is shortened, the amount of the spout is regulated. However, in the present invention, the spout 23 of the standing pouch 1 inserted into the bottle is set to a size that can be easily inserted into the bottle. When the pouring was actually started, the contents were almost smoothly poured into the bottle 30 from the spout 23 which was fully opened to the mouth 31 of the bottle. Then, the amount of pour was sufficiently satisfactory, and there was no fear that the amount of pour was regulated as in the related art. Therefore, when setting the length L, firstly, it is more ideal that the length L is set slightly shorter than the equal size in consideration of the ease of insertion of the bottle 30 into the mouth portion 31.
