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, A refillable pouch is provided with a vertical folding line for facilitating folding 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.

By adopting such a configuration, since the upper part of the pouch has a constricted shape, the pouch has a smart appearance similar to 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, using the vertical folding line provided in the center of the pouch, and gradually pour it out, so that the top of the pouch has a narrow width , So that even if the entire upper part is opened, the width of the opening is substantially half that of the opening, so that the contents can be safely and quickly poured out without spilling out. it can. Then, according to the weight loss of the content, gradually pour it out along the bending line to the bottom of the pouch, and in the final stage, the entire pouch is half the width, so the viscosity of the content is compared. Even when the target is high, it is easy to squeeze out by hand, and the contents 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.

[0011] The easy-opening means may be a notch commonly used in ordinary pouches, a half-cut line by irradiating a laser beam or the like, 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, and 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.

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, the 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 a 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 portions is changed to a seal pattern capable of heat-sealing the upper portion in a constricted shape by using a corresponding bag making machine. In addition, a trimming device is added, and an easy-opening means such as a notch or a half-cut line, and a processing device for processing an additional component such as a pouch bending line, that is, a punching device, a laser beam irradiation device And the embossing device,
