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 a liquid content such as a liquid material, which is sealed and packaged, and the content is transferred to another container at the time of use. Is relatively high in viscosity,
When pouring, the pouch can be poured out from the top to the bottom while gradually folding it in half in the vertical direction so that it can be easily transferred to the end.The pouch shape is designed so that the contents can be easily squeezed out even at the final stage. It relates to an improved refill pouch.

[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 high productivity in the process, the contents can be easily filled, and when the contents are used, even if the contents are relatively high in viscosity, they can be easily squeezed and transferred without leaving the contents to the end. An object of the present invention is to provide a refillable pouch which is inexpensive and excellent in suitability for use.

[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. A perforated line for forming a content spout is provided, and a vertical perforated half-cut line for facilitating folding of the pouch when pouring the content at the center of the pouch. And a refill pouch.

The above-mentioned cut line may be displayed by printing, and may be provided in an arbitrary shape according to the viscosity of the contents and the size of the mouth of the container to be transferred. The perforated half-cut line is a line in which half-cut cuts are provided intermittently, and the lengths and intervals between the cuts are appropriately determined according to the configuration and thickness of the laminated film of the pouch. Can be set. A continuous half-cut line can make the pouch easier to bend,
This is not preferable because the pouch may have an excessively large decrease in bag breaking strength or the like.

[0008] The method of providing the above-described perforated half-cut line by irradiating a laser beam is less likely to cause cracks or the like at the edge of the cut than a mechanical means using a cutting tool such as a perforated blade. This is preferable in that a line can be provided. Such a perforated half-cut line may be provided only on the wall film (laminated film) on one side of the pouch, but may be provided at a position where the center portion of the wall film (laminated film) on both sides overlaps. More preferred. In addition, at the time of printing the cut-out line, at the same time, printing of a pattern or a display item related to the content for improving the designability is also performed, but further, when the content is used, the perforated half is used. It is preferable to add a picture or explanation indicating that the pouch is to be poured out while being bent at the cut line.

By employing such a configuration, when using the contents filled in the pouch, that is, when transferring the contents to another container, first, along the cut line provided at the edge of the upper part of the pouch. Then, cut off the upper heat seal part and open it, and then, firstly, fold the upper part of the pouch in two by the vertical perforated half cut line provided in the center part of the pouch, and gradually tilt it. By pouring out,
Even when the entire top of the pouch is opened, the width of the opening is substantially halved, so that the contents can be quickly poured out without spilling out. As the weight is reduced, the pouch is gradually bent to the bottom of the pouch with a perforated half-cut line and poured out.At the final stage, the entire pouch is half the width, so the viscosity of the contents can be compared. Even when the target is high, it is easy to squeeze out by hand, and the transfer can be performed quickly and easily without leaving the contents.

[0010] The invention described in claim 2 is the refillable pouch according to claim 1, wherein the cutout line is provided so as to partially cut off a central portion of an upper portion of the pouch. The cutting line may be any shape as long as the pouch can be opened by partially cutting off the center of the upper part of the pouch, and the shape can be provided in any shape such as a V-shape, a U-shape, and a semi-circle. The size, that is, the width and depth of the cut line by the cut line can be appropriately determined depending on the viscosity of the contents and the size of the mouth of the container to be transferred. However, after opening the pouch, when the pouch is bent by a vertical perforated half-cut line provided in the center thereof, it is more preferable that the cutouts on both sides coincide with each other. It is preferable to provide the shape so as to be symmetrical with respect to the half-cut line.

By adopting such a configuration, when pouring out the contents filled in the pouch, the size of the spout is adjusted according to the viscosity of the contents and the size of the mouth of the container to be transferred. , Can be adjusted as appropriate, so that the contents can be transferred more safely in addition to the effects of the invention described in claim 1.

According to a third aspect of the present invention, there is provided the refillable pouch according to the first aspect, wherein the cutout line is provided so as to cut off both side edges of the upper part of the pouch. Also in this case, when the pouch is opened with the above-mentioned perforated line, and when the pouch is bent at the vertical perforated half-cut line provided at the center portion, it is more preferable that the cutouts on both sides coincide with each other. It is preferable to provide a symmetrical shape with respect to the perforated half-cut line. Therefore, the cutout lines can be provided in the corners on both sides of the upper part of the pouch, for example, in a shape forming a C-shape or the like. In addition, the size of the cut line, that is, the size of the cutout can also be appropriately determined according to the viscosity of the contents and the size of the mouth of the container to be transferred.

[0013] By adopting such a configuration, when the content filled in the pouch is poured out, the size of the spout corresponds to the viscosity of the content and the size of the mouth of the container to be transferred. Therefore, the contents can be adjusted appropriately, so that the contents can be transferred more safely in addition to the operation and effect of the invention described in claim 1.

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

The above-mentioned easy-opening means may be a method of laminating a uniaxially stretched film in a laminated film of a pouch or a half cut line by laser light irradiation or the like, in addition to a notch often used in an ordinary pouch. 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 also 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 such as a straight line or a curve, but may be an intermittent half-cut line such as a perforated line. 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. The half-cut line is provided to facilitate opening of the pouch, and has a different purpose from the vertical perforated half-cut line provided at the center of the pouch. 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 function and effect of the invention described in any one of the above-mentioned claims 1 to 3, no tool such as scissors is required when the pouch is opened with a cutting line. It can be easily cut and opened by hand alone.

According to a fifth aspect of the present invention, there is provided the refillable pouch according to any one of the first to fourth aspects, wherein the pouch is a standing pouch type pouch.

By adopting such a configuration, in addition to the functions and effects of the invention according to any one of the above-mentioned claims 1 to 4, the pouch is provided with autonomy and, in particular, the pouch after the contents are filled. In addition to being easy to handle, the external appearance is also excellent, and when the contents are transferred, the contents can be stopped and put upright, so that the transfer operation can be easily performed.

[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, 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.

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

For example, depending on the use conditions of the pouch, paper or synthetic paper can 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 that case, paper or synthetic paper is excellent in whiteness, so that the printing effect is enhanced and the design of the pouch can be improved. Further, in the case of paper, since the paper is easily foldable, when the pouch is bent at a perforated half-cut line, the pouch has good shape retention and the contents can be more easily poured out.

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 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 can be 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 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 for manufacturing the refill pouch of the present invention, which is manufactured using the above-described laminated film, will be described. The shape 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.
