Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pouch for refilling which is used for hermetically packaging contents having fluidity such as a liquid material and transferring the contents to another container at the time of use. While the shape is smart and excellent in design, when pouring out the contents, even if the contents are relatively viscous, the pouch is gradually moved vertically from the top to the bottom so that it can be easily transferred to the end. The present invention relates to a refill pouch having an improved pouch shape so that it can be poured out while being folded in two, and the contents can be easily squeezed out even in the final stage.

[0002]

2. Description of the Related Art Conventionally, refillable pouches in which fluid contents such as liquids are sealed and packaged, and the contents are transferred to another container at the time of use, include, for example, a part of the upper part of the pouch. A spout with a protruding shape with a narrower width is provided.Also, the spout is further embossed so that the spout does not block during the pouring. Or a separate spout made of a plastic molding or the like attached by heat bonding to a part of the upper part of the pouch.

[0003]

However, a pouch with a protruding spout having a reduced width is provided at a part of the upper part of the pouch, and the spout is formed by embossing the spout. Those with improved shape retention can be used favorably for low-viscosity contents,
When the viscosity of the contents becomes high, there is a problem that the dispensing speed decreases rapidly, it takes a long time to dispense, and the contents are liable to remain in the pouch at the final stage of the dispensing.

[0004] In addition, a separate spout made of a plastic molding or the like is attached to a part of the upper part of the pouch. If the viscosity of the content is relatively low, it can be suitably used, but the viscosity of the content is high. In addition to the above-mentioned problems, the number of pouch manufacturing processes increases and the spout itself becomes expensive, and the empty pouch with the spout increases in thickness, so that the cost of storage and transportation is also high. When filling the contents, for example, the number of empty pouches to be loaded into the feeder section of the filling machine is greatly reduced, which requires the operator to frequently supply empty pouches, increasing overall costs. In addition, there is a problem that the complexity of the process and the work increases.

The present invention has been made in order to solve such a problem, and an object of the present invention is to eliminate the need for a separate spout of a molded article or the like, and to provide a similar pouch as a normal pouch. It can be manufactured with good productivity in the process, the pouch shape is smart and excellent in design, and it is easy to fill the contents.When using the contents, even if the contents are relatively high in viscosity, the contents are completed to the end An object of the present invention is to provide an inexpensive and reusable pouch that can be easily squeezed and transferred without leaving any objects.

[0006]

The above objects can be attained by the present invention described below. That is, the invention described in claim 1 is a pouch in which the peripheral edge portion is heat-sealed in a bag shape, and the content having fluidity is hermetically packaged, and the upper portion of the pouch is narrow in a constricted shape. The pouch is formed to have a width, and a cutout line is formed at an upper edge portion of the pouch to form a spout of the content, and further, when the content is poured out at a central portion of the pouch, The refillable pouch is provided with a vertical perforated half-cut line for facilitating bending of the pouch.

[0007] Since the refill pouch of the present invention is formed to have a narrowed upper portion and a narrow width, the cutout line is provided so as to cut off the upper edge, ie, the entire upper heat seal portion. Depending on the viscosity of the contents and the size of the mouth of the container to be transferred, it may be smaller, for example, provided so that the center of the upper part of the pouch is partially cut into an arbitrary shape such as a V-shape. You can also. Such a cut line may be displayed by printing, and can be easily provided at the same time as printing a pattern on a pouch.

[0008] The perforated half-cut line is a line in which half-cut cuts are provided intermittently. The length and interval of each cut are determined by the configuration and thickness of the laminated film of the pouch. It can be set appropriately. Regarding the depth of the half-cut line, it is not always necessary to set the depth to half the thickness of the laminated film of the pouch,
Although this also depends on the configuration of the laminated film, in order to reduce the strength reduction such as the pouch breaking strength, the thickness can be reduced to, for example, 1/5 to 1/3 of the thickness of the laminated film. . Further, a continuous half-cut line can make the pouch easily bendable, but is not preferable because the strength of the pouch, such as the breaking strength, may be too large.

The method of providing such a perforated half-cut line by irradiating a laser beam, rather than mechanical means using a cutting tool such as a sewing machine blade, removes a part of the laminated film into a line by melting and mist. Since it is formed so that it is bent, it is preferable in that it is easy to bend, a crack is not easily generated at the edge of the cut, and a stable half-cut line can be provided. Such a perforated half-cut line may be provided only on the laminated film on one side wall of the pouch, but is more preferably provided at a position where the central portion of the laminated film on both side walls overlaps.

In addition, when the cutout line, the pattern for improving the design of the pouch, or the display items related to the contents are printed on the laminated film on the wall surface of the pouch, and simultaneously when the contents are poured out. It is preferable to add a picture or explanation indicating that the pouch is to be poured out while being bent in the vertical direction at the perforated half-cut line.

By adopting such a configuration, since the upper part of the pouch has a constricted shape, it has a smart appearance resembling a container such as a bottle, and is excellent in design. Also,
When using the contents filled in the pouch, that is, when transferring to another container, first, along the cut line provided at the edge of the upper part of the pouch, cut off the upper heat seal part Open the pouch, and then fold the top of the pouch in two at first with the vertical perforated half-cut line provided at the center of the pouch, and gradually pour it out, so that the top of the pouch is constricted The width of the opening is substantially half that of the entire upper part, even if the entire upper part is unsealed, so that the contents can be spilled safely and quickly without spilling out. Can be poured out. Then, according to the weight loss of the contents, gradually pour it out to the lower part of the pouch with a perforated half-cut line, and in the final stage, the entire pouch is half width, so the contents are Even when the viscosity of the object is relatively high, it is easy to squeeze out by hand and can be quickly and easily transferred without leaving the contents.

According to a second aspect of the present invention, there is provided the refillable pouch according to the first aspect, wherein the perforated line is provided with an easy-opening means.

[0013] The easy-opening means may be a notch commonly used in ordinary pouches, a half-cut line by laser light irradiation, or a method of laminating a uniaxially stretched film in a laminated film of a pouch (in this case, a uniaxially stretched film). The stretched film is used so that the stretching direction thereof coincides with the direction of the cutout line), and there is affixing of a cut tape, and these may be used alone.For example, a notch, a half cut line, or It can be used in an appropriate combination such as lamination of a uniaxially stretched film or sticking of a cut tape.

When the half-cut line is provided, the half-cut line is not limited to a continuous half-cut line, but may be an intermittent half-cut line such as a perforated shape. Also, such a half-cut line may be one, but assuming that the tearing direction is shifted, a plurality of half-cut lines such as one each or two each on both sides of the center half-cut line. Can be provided in parallel. In addition, as the notch, a one-shaped or V-shaped notch is usually used, but the shape is not particularly limited, and any shape having a pointed portion in a cutting direction can be used.

By adopting such a configuration, in addition to the operation and effect of the invention described in the first aspect, when the pouch is opened with the cut-out line, tools such as scissors are not required, and the pouch can be easily operated only by hand. Can be cut and opened.

According to a third aspect of the present invention, there is provided the refill pouch according to the first or second aspect, wherein the pouch is formed in a standing pouch format.

By adopting such a configuration, in addition to the function and effect of the invention described in claim 1 or 2, the pouch is provided with autonomy, and in particular, the handling of the pouch after the contents are filled is improved. In addition to being easy, as described above, the upper part of the pouch is formed in a constricted shape, so that it becomes a smart shape more similar to a three-dimensional container such as a bottle, and when transferring the contents, Since it can be stopped and set up, the transfer operation can be performed more easily.

[0018]

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, any known laminated film used for various liquid pouches, Can be used. From these, suitable ones can be freely selected and used according to the use conditions such as the type of contents to be packaged and the presence or absence of heat treatment after filling.

Representative examples of the structure of the laminated film that can be preferably used include the following structures. (1) ON film / adhesive / L / LDPE film (sealant layer) (2) ON film / adhesive / uniaxially or biaxially oriented H

Aluminum foil / adhesive / CPP film (sealant layer) (12) PET film / adhesive / EVOH film / adhesive / ON film / adhesive / CPP film (sealant layer) Instead, various combinations of laminated films can be used.

For example, depending on the use conditions of the pouch, paper or synthetic paper may be laminated on the entire surface or a part of the intermediate layer such as the inner side of the outermost layer of the laminated film.
In this case, since the paper or the synthetic paper has excellent whiteness, the printing effect is enhanced, and the design property can be improved.

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 a base film, and the uniaxially stretched HDPE film and the uniaxially stretched PP film of the intermediate layer are used. ,
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.

An aluminum foil, a silica or alumina vapor-deposited layer, an EVOH film and the like are laminated to provide gas barrier properties. Further, as the sealant layer, two examples of an L-LDPE film and a CPP film have been described.
Excellent heat seal stability and content resistance, such as stress cracking resistance to surfactants.
The film is excellent in heat resistance and low odor, and is suitable for packaging contents requiring these properties.

In the sealant layer, in addition to the above, depending on the contents 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 refill pouch of the present invention is formed with a narrow width in the shape of a constricted upper portion, but this portion is heat-sealed with a seal pattern corresponding to the constricted shape on the side of the pouch, and trimming an excess portion. Thereby, it can be easily formed. Accordingly, the type of the pouch main body is not particularly limited, and for example, it can be easily manufactured as an applied form based on a standing pouch or the like in addition to a three-side seal type or a four-side seal type pouch.

That is, according to the type of pouch to be employed, the seal pattern for heat-sealing the side portion is changed to a seal pattern that can be heat-sealed to a constricted upper portion by using a corresponding bag-making machine. In addition, a trimming device is added, and an easy-opening means such as a notch and a half-cut line, and a processing device for processing an additional component such as a perforated half-cut line of a pouch, that is, a punching device A pouch can be easily manufactured by incorporating a laser beam irradiation device or the like in-line or separately preparing it off-line.
