[0020]

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, embodiments of the present invention, such as a film used for a refill pouch of the present invention and a method for manufacturing a pouch, will be described. The film used for the refill pouch of the present invention is mainly a laminated film mainly composed of plastics, but is not particularly limited, for example, a known laminated film used for various liquid pouches and the like, Can also be used, and from these, suitable ones can be freely selected and used according to the use conditions such as the type of contents to be packed and handling after filling.

A typical example of the structure of the laminated film which can be preferably used is as follows. (1) ON film / adhesive / L / LDPE film (sealant layer) (2) ON film / adhesive / uniaxially or biaxially oriented H
DPE film / adhesive / L / LDPE film (sealant layer) (3) ON film / adhesive / uniaxially or biaxially oriented P

Aluminum foil / adhesive / CPP film (sealant layer) (13) PET film / adhesive / EVOH film / adhesive / ON film / adhesive / CPP film (sealant layer) Instead, various combinations of laminated films can be used.

When the laminated film is configured to include a paper layer, it is not particularly limited, but both sides of the paper are placed on the intermediate layer such as the innermost layer of the laminated film.
It is preferable to laminate the film, such as a film, an ON film, and a biaxially stretched PP film so as to be sandwiched between the films. By laminating in this way, the lack of water resistance of the paper itself is supplemented, and when printing a pattern or the like on the pouch, the inner surface of the outermost film and the outer surface of the paper, either one of the surfaces, In addition, printing can be arbitrarily performed on both surfaces, and the printing effect can be improved by the whiteness of the paper. Further, the paper may be laminated on the entire surface of the laminated film, or may be partially laminated.

When the paper is laminated on the entire surface of the laminated film, similarly to the lamination of the other films, the paper is laminated by a dry lamination method using an adhesive, and a thermo-adhesive resin such as polyethylene is laminated on the laminated surface with a T die. It can also be laminated by an extrusion lamination method in which the film is extruded and pressed. Further, when the paper is laminated on a part of the laminated film, for example, in the shape of a strip or the like, it can be easily laminated by the extrusion lamination method.
When paper is laminated, the paper is excellent in whiteness, so that the printing effect is enhanced as described above, and the design of the pouch can be improved. In addition, the rigidity of the laminated film is also increased, so that the laminated film is easily bent, so that the effect of the bending line can be further enhanced.

In the above, the ON film is a biaxially stretched nylon film, the L / LDPE is a linear low density polyethylene, the HDPE is a high density polyethylene, the LDPE is a low density polyethylene, the PP film is a polypropylene film, and the PET film is biaxially stretched. A polyethylene terephthalate film and an EVOH film indicate a saponified ethylene-vinyl acetate copolymer film, and a CPP film indicates a non-stretched polypropylene film. In addition, the anchor coat is a kind of primer coat that is previously coated on the base film side in order to improve adhesiveness when laminating a resin by extrusion coating.

In the construction of the laminated film described above, the outermost ON film and the PET film provide the pouch with mechanical strength and printability as the base film, and the uniaxially stretched HDPE film and the uniaxially stretched PP film of the intermediate layer are used as the base film. ,
If the cutting line when opening the pouch is constant, such as in the horizontal direction, by using the stretching direction so as to match the direction of the cutting line of the pouch, one of the easy-opening means is to improve the directionality of the tear. Can be stabilized. When the cut lines are in a plurality of directions such as an oblique direction and a vertical and horizontal direction, the biaxially stretched H
It is preferable to use a DPE film or a biaxially stretched PP film.

A vapor-deposited layer of silica or alumina, a vapor-deposited aluminum layer, an aluminum foil, an EVOH film and the like are laminated to provide gas barrier properties. Also, as the sealant layer, two examples of the L·LDPE film and the CPP film have been described.
LDPE films are excellent in heat sealing stability and content resistance, such as stress cracking resistance to surfactants, and CPP films are excellent in heat resistance and low odor. Suitable for packaging of goods.

In the sealant layer, in addition to the above, depending on the content to be filled, ethylene / α-olefin copolymer, ethylene / vinyl acetate copolymer, ethylene / acrylic acid copolymer, ethylene / acrylic ester copolymer may be used. Polymers, ionomers, polyester resins and the like can also be appropriately selected and used.

In particular, an ethylene / α-olefin copolymer obtained by polymerization using a single-site catalyst such as a metallocene catalyst has a narrow molecular weight distribution and a stable copolymerization ratio, so that the low-temperature heat sealability and It is excellent in hot sealability, and is suitable for a sealant layer of a pouch having a step due to a difference in film overlap with a heat seal portion such as a standing pouch in that the occurrence of pinholes due to seal missing can be prevented. . Furthermore, by using a blend of the copolymer and an olefin elastomer, the heat fluidity of the sealant layer is improved, and the generation of pinholes due to the steps can be more effectively prevented.

Next, a method of manufacturing the refill pouch of the present invention, which is manufactured using the above-described laminated film, will be described. The type of the main body portion of the refill pouch of the present invention is not particularly limited, and for example, a pouch of a three-side seal type, a four-side seal type, and a standing pouch can be suitably used. Then, according to the pouch type to be adopted, using the corresponding bag making machines, additional configuration such as easy-opening means such as notches and half-cut lines, notches, and pouch bending lines A pouch can be easily formed by incorporating a processing device for processing the part, that is, a punching device, a laser beam irradiation device, an embossing device, a hot press molding device, or the like in-line, or separately preparing it as an off-line. Can be manufactured.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below more specifically with reference to the drawings. However, the present invention is not limited to these drawings. 1 to 4 are plan views each showing the configuration of one embodiment of the refill pouch of the present invention. And FIG. 5 is a perspective view of a main part for explaining a pouring method when the contents filled in the refill pouch shown in FIG. 2 are transferred to another container, and FIG. FIG. 4 is a perspective view of an essential part for explaining a pouring method when transferring the contents filled in the refill pouch shown in FIG. 3 to another container.

FIG. 1 shows a first embodiment of a refill pouch according to the present invention.
It is a top view which shows the structure of Example of this. The pouch 100 for refilling shown in FIG. 1 has its main body formed in a standing pouch form, and its bottom portion is folded inward between the lower portions of the laminated films 1 on both side walls according to a conventional method. In the vicinity of the lower end on both sides of the bottom film formed in the form of a gusset formed by being inserted and folded inward, in this case, a semicircular bottom film cutout 5,
5 is provided, and the gusset part is a bottom seal part 2 of a ship bottom shape.
The body is formed by heat-sealing the edges of both sides with the side seals 3, 3, and is formed in a bag shape with an open top. The upper seal portion 4 is an unsealed opening before filling the contents, and after filling the contents from this portion, the upper seal portion 4 is heat-sealed by a degassing seal or the like to be sealed. This is the same in the refill pouch shown in FIGS.

A vertical bending line 6 is provided at the center of the pouch 100, that is, at the center of the laminated film 1 on the wall surface. Direction cutting line 7 and a notch 8 at the end thereof, and in this case, the folding line 6
On the lower extension of the pouch 100 on the lower extension of
A cut-out portion 9 is provided so as to cut out a part of the bottom seal portion 2. The notch 9 is provided for further reducing the resistance when the pouch is bent at the bending line 6, and can be removed when unnecessary.

The laminated film 1 on the pouch wall has
In this case, a laminated film having a paper layer laminated on the entire surface is used. The laminated film 1 including such a paper layer includes:
It may be used on both side walls of the pouch, but it may be used only on one wall surface and a laminated film containing no paper layer on the other wall surface. It is preferable that the bending line 6 is also provided at the center of the laminated film 1 on both side walls so as to overlap at the same position because it is easier to bend. However, it can be provided only on the laminated film on one wall. In such a case, it is preferable to provide it on a laminated film including a paper layer.

The cutout line 7 may be displayed only by printing, but in combination with the notch 8, a half-cut line, an easy-opening means such as laminating a uniaxially stretched film, or attaching a cut tape is used in combination. It is further preferable that the upper part of the pouch can be easily cut by hand and reliably opened along the cutout line 7 by hand.

By adopting such a configuration, the refill pouch 100 is of the standing pouch type, so that the pouch 100 filled with the contents is self-supporting, easy to handle, and excellent in appearance. Further, since the paper layer is laminated on the entire surface of the laminated film 1 on the pouch wall surface, the printing effect is enhanced, the design property of the pouch is improved, and at the same time, a moderate rigidity is imparted and the bending line 6 is sharp. The pouch 100 can be easily folded along the folding line 6.

The contents can be easily filled from the upper opening, and the upper seal portion 4 can be sealed by heat sealing. When transferring the filled contents to another container, first, the upper seal portion 4 on the upper part of the pouch is cut off along the perforation line 7 using the notch 8, and is opened. First, the upper part of the pouch is folded in half by the vertical folding line 6 of the part, and the content is removed by gradually sloping the pouch so that the width of the opening is substantially halved. Without spilling
In the final stage, the pouch 1 can be poured quickly by pouring it out along the folding line 6 to the lower part of the pouch as the content is reduced.
00 is half the width, and the rigidity of the laminated film 1 is higher than that of the paper layer. Therefore, even when the viscosity of the content is relatively high, it is easy to squeeze out by hand, It can be quickly and easily transferred without leaving.

FIG. 2 shows a second embodiment of the refill pouch of the present invention.
It is a top view which shows the structure of Example of this. FIG. 5 is a perspective view of a main part for explaining a pouring method when the contents filled in the refill pouch shown in FIG. 2 are transferred to another container. However, the shape of the pouch is shown at the time when it is close to the final stage of pouring. Refill pouch 200 shown in FIG.
In the configuration of the refill pouch 100 shown in FIG. 1, the cutout line 7 for forming the spout and the notch 8 provided at the end thereof are changed to the illustrated shape and position,
Further, the laminated film 1 used for the pouch wall is changed to a configuration in which the paper layer is laminated on a part of the paper layer instead of the entire surface.

That is, in the laminated film 1, there is no paper layer in the portion where the cutout line 7 is provided on the upper part of the pouch.
The laminated film 1 has a configuration in which a paper layer whose upper part is cut in a pattern is laminated on a portion indicated by a paper layer laminating portion 10 below the cut line 7, and the cut line 7 is The shape is changed to a V-shape so that the vertex of the V-shape overlaps the folding line 6 at the edge of the upper central portion of the pouch 200, that is, the cutout line 7 is symmetrical on the left and right sides of the folding line 6. The V-shaped cut line 7 is provided with notches 8a and 8b at both ends (upper end). This configuration corresponds to one embodiment of the invention described in claim 2. In addition, the cutting line 7
May be displayed only by printing, but notches 8a and 8b
In combination with the above, a half-cut line can be provided in this portion.

By adopting such a configuration, it is possible to obtain the same functions and effects as those of the refill pouch 100 shown in FIG.
That is, since the paper layer laminated on the laminated film 1 is removed from the portion where the cutout line 7 is provided on the upper part of the pouch, and the upper part is cut in a pattern, the design becomes more stylish and the design is improved. At the same time, the opening of the pouch 200 by the perforated line 7, that is, the formation of the spout becomes easier, and the size of the spout also depends on the viscosity of the contents and the size of the mouth of the container to be transferred. By adjusting the width and depth of the V-shape, it can be easily adjusted.

Therefore, when using the contents filled in the pouch 200, for example, by folding the upper part of the pouch in two along the folding line 6, the notches 8a, 8b on both sides are provided.
And the cut line 7 overlaps at the same position, so that the notch 8a
, 8b at the same time tearing obliquely along the perforated line 7, the center of the upper part of the pouch can be easily opened in a V-shape.

When the contents are transferred to another container, as shown in FIG. 5, the opening of the container 50 is set up with the opening of the folded upper part facing downward and the opening part standing. The size of the opening is adjusted in accordance with the viscosity of the contents and the size of the mouth of the container 50 to be transferred by starting the pouring toward the container. It can be poured more safely than the pouch 100.
And after that, pouch 2 gradually according to the weight loss of the contents
00 can be safely poured out by bending it to the lower part along the folding line 6, and at the final stage, the entire pouch 200 has a half width as shown in the drawing. Since the rigidity of the laminated film 1 is also increased by the paper layer of the paper layer laminated portion 10, even when the viscosity of the content is relatively high, it is easy to squeeze out by hand,
It can be quickly and easily transferred without leaving the contents.

FIG. 3 shows a third embodiment of the refill pouch of the present invention.
It is a top view which shows the structure of Example of this. FIG. 6 is a perspective view of an essential part for explaining a pouring method when the contents filled in the refill pouch shown in FIG. 3 are transferred to another container. Also in this case, the shape of the pouch is shown as a shape close to the final stage of pouring.

The refill pouch 300 shown in FIG.
In the configuration of the refill pouch 200 shown in FIG. 2, the laminated film 1 used for the pouch wall has a configuration in which the paper layer is further reduced, that is, as shown in the paper layer lamination portion 10, the lower part of the pouch 300 From the middle to the area slightly above the middle, a paper layer with a pattern-shaped upper part is changed to a laminated structure, and a V-shaped cut line provided at the center of the upper part of the pouch 7 and the notches 8a, 8b at both ends thereof as shown in FIG.
The cutting lines 7a and 7b are provided in a shape (shape on both sides) that obliquely cuts the corners on both sides of the upper part of 00, and the notch is a notch 8a at the upper end of the cutting line 7a. And a configuration in which a notch 8b is provided at the upper end of the perforated line 7b.
A notch 9 is provided at the lower end of the center of the pouch 300 so as to cut off a part of the bottom seal 2, and the upper seal 4 is attached to the upper end of the pouch 300 on the extension line above and below the folding line 6.
Notch 9a is provided so as to cut out a part of
The configuration is such that a cutout 9b is provided at the lower end of the pouch 300 so as to cut off a part of the bottom seal portion 2. This configuration corresponds to an embodiment of the invention described in claim 3.

Also in this case, the notches 9a, 9b
When pour out the contents, the pouch 300
Is provided as an auxiliary to make it easy to bend, and can be removed when unnecessary. The cut lines 7a and 7b may be displayed only by printing,
A half cut line can be provided in combination with the notches 8a and 8b.

By adopting such a configuration, the refill pouch 300 has a structure in which the paper layer laminated on the laminated film 1 on the wall surface has the refill pouch 20 shown in FIG.
Although it is smaller than the case of 0, since it is laminated from the lower part of the pouch where the weight of the contents is applied to the middle stage to a position slightly higher than the middle stage, the rigidity of the laminated film 1 in this part is increased, and the pouch form is increased. As well as being stable, the effect of the bending line 6 in this part and the printing effect are improved,
Since the upper part of the paper layer is cut in a pattern, the pouch becomes more stylish and the design of the pouch is improved.

Then, cut lines 7a, 7 on the upper part of the pouch
Since there is no paper layer in the portion where b is provided,
It becomes easier to open the pouch 300 with a and 7b, that is, to form a spout. Regarding the size of the spout, depending on the viscosity of the contents and the size of the mouth of the container to be transferred,
It can be easily adjusted by displacing the positions of the cut lines 7a and 7b. Further, since notches 9a and 9b are provided in the center of the upper and lower ends of the pouch 300, a part of the upper and lower heat seal portions is cut off, so that the pouch 300 can be folded along the folding line 6. The repulsive force of the portion is weakened, and the portion can be bent more easily.

Therefore, when using the contents filled in the pouch 300, the cut lines 7a, 7b provided at the corners on both sides of the upper part of the pouch are notched 8a at the respective ends.
, 8b may be separately cut and opened, but by folding the upper part of the pouch 300 in two along the folding line 6, the cut lines 7a, 7b and the notches 8a, 8b on both sides become the same. Notch 8a
, 8b at the same time along the perforations 7a, 7b, the upper corners on both sides can be easily torn open.

Since the size of the opened opening is adjusted in accordance with the viscosity of the contents and the size of the mouth of the container to be transferred, the size of the opening is kept as shown in FIG. Container 50 in the form of an opening with its part facing down
Of the pouch 300 by gradually starting to pour it toward the mouth of the pouch 300 and gradually pour it out along the bending line 6 to the lower part of the pouch 300 in accordance with the weight loss of the contents, so that the pour can be safely and rapidly performed. it can. Also, at the final stage of the pouring, as shown in the drawing, the entire pouch 300 is half the width, and further, paper is laminated on the paper layer laminating portion 10 of the pouch, so that the rigidity is high. Even when the viscosity of the contents is relatively high, the contents can be easily squeezed out by hand, and the contents can be quickly and easily transferred without leaving the contents.

Next, FIG. 4 is a plan view showing the configuration of a fourth embodiment of the refill pouch of the present invention. The refill pouch 400 shown in FIG. 4 is formed by changing only the type of the pouch body from the standing pouch type to the four-side seal type in the configuration of the refill pouch 100 shown in FIG. The configuration is shown in Fig. 1.
Is constructed similarly to the refill pouch 100 shown in FIG.

By adopting such a configuration, the refill pouch 400 is a four-sided seal type pouch, so it is not self-supporting, and is somewhat inferior in terms of ease of handling of a pouch filled with sealed contents. In addition to easy bag making and stable heat sealing, there is an advantage that it can be manufactured at low cost in terms of cost. The other configuration is the same as that of the refill pouch 100 shown in FIG. 1, so that the same operation and effect as those described for the refill pouch 100 can be obtained.

Also, for the refill pouches 200 and 300 shown in FIGS. 2 and 3, similarly to the case of the refill pouch 400 shown in FIG. In this case, the same effects as those of the refill pouch 200 or the refill pouch 300 shown in FIG. 2 or FIG. 3 can be obtained, except that the characteristics of the standing pouch type are changed to the characteristics of the four-side seal type pouch. Various operational effects can be obtained.

[0052]

As described above, according to the present invention, there is no need for a separate spout made of a molded product or the like.
It can be manufactured with the same process as ordinary pouches with good productivity, the contents can be easily filled, and since the paper is laminated on the laminated film on the pouch wall, the rigidity is increased, and the effect of the bending line is improved. In addition, the printing effect is good and the design of the pouch is improved, especially if the pouch body is of the standing pouch type, the pouch becomes more autonomous,
It is easy to handle and excellent in appearance, and when transferring the filled contents to another container, the top of the pouch can be easily cut off along the cut line and opened, and furthermore, the pouch can be opened. With the vertical bending line provided in the center of the pouch, the contents can be poured out while gradually folding the pouch from the top to the bottom, and the size of the opening can be adjusted appropriately, Even if the content is relatively high in viscosity, it can be quickly and easily transferred to the end without spilling to the outside, so that an inexpensive and excellent reusability pouch can be provided with good productivity. .
