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,
At the time of pouring, the pouch is gradually folded vertically from the top to the bottom so that it can be easily transferred to the end, so that the pouch can be poured out, and the pouch shape 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, resulting in an overall cost increase. 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 contents can be easily filled, and the shape of the pouch is smart and excellent in design, and when using the contents, even if the contents are relatively high in viscosity, It is an object of the present invention to provide an inexpensive and reusable pouch that can be easily squeezed and transferred without leaving the contents.

[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. In addition to being formed in a width, a cutout line for forming a spout of the contents is provided at an upper edge portion, and further, at the center of the pouch, when the contents are poured out, the pouch is removed. The refill pouch is provided with a vertical heat seal portion for facilitating bending.

The above-mentioned cut line may be displayed by printing. Usually, the cut line is provided along the heat seal portion on the top of the pouch and inside the heat seal portion so as to cut out the entire upper seal portion. Depending on the size of the mouth of the container to be transferred, it may be smaller, for example, provided at the center of the upper part of the pouch so as to cut out a part of the upper seal portion into a V-shape or the like. That is, the cutout line can be provided in any shape and size as long as the cutout line is suitable for discharging the contents.

A vertical heat seal portion provided at the center of the pouch is for facilitating bending of the pouch. For example, a long heat seal portion is provided from the lower end of the pouch to a middle stage or a position slightly above the middle stage. The pouch may be provided in a part of the length direction, or may be provided so as to bisect the pouch over the entire length in the length direction. In addition, at the time of printing the cut-out line, at the same time, printing such as display items related to the design and the content to improve the design, is also performed, when further using the content, the vertical heat sealing It is preferable to add a picture or explanation indicating that the pouch is to be poured out while bending the pouch.

By adopting such a configuration, the upper part of the pouch is formed in a narrow shape with a narrow width.
The outer shape looks smart like a container such as a bottle, and the design is excellent. The contents can be easily filled from the opening at the top of the pouch and sealed by a degassing seal or the like. In addition, when using the filled contents, first, along the cut line provided at the edge of the upper part of the pouch, cut off the upper heat seal part and open it, and then, in the center part of the pouch By the provided vertical heat sealing part, first the upper part of the pouch is folded in two, the opening is oriented vertically, and the pouch is gradually inclined and poured out, so that the entire upper part of the pouch is opened. Even if it is, the width of the opening is substantially halved, and since the opening is oriented vertically, the discharging width is further narrowed, so that the contents can be quickly spilled without spilling out. Can be poured out. Then, according to the weight loss of the contents, the pouch is gradually bent to the lower part of the pouch with a vertical heat seal part and poured out, so that in the final stage, the entire pouch is half the width, so the contents are Even when the viscosity 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.

[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 such as a straight line or a curve, and 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. May be provided in parallel or in a shape converging on the center line. 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.

[0013] 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, the bottom of the pouch has a shape in which a bottom portion of a standing pouch type is provided in parallel on both sides of a vertical heat seal portion provided at a center portion of the pouch. The refill pouch according to claim 1 or 2, which is formed.

[0015] The bottom of the standing pouch type is
It is formed to give the pouch independence,
Like the lower part of a normal standing pouch, it is formed in the form of a gusset formed by folding the bottom film inward and inserting it between the lower parts of the wall films on both sides. A semicircular or other bottom film cutout portion is provided, and the gusset portion is formed by heat sealing with a ship bottom shape seal pattern. The above ship bottom seal pattern is
It may be a ship bottom shape in which both sides rise in a curved shape from both sides from the center of the bottom, or a ship bottom shape in which both sides rise in an inclined straight line from the bottom having a fixed width and length.

That is, in the pouch for refilling according to the third aspect of the present invention, the lower part of the pouch for refilling according to the first or second aspect of the invention is provided with a vertical heat seal provided at the center of the pouch. The bottom of the above-mentioned standing pouch type is provided in parallel on both sides of the portion, and is a modified type of standing pouch different from a normal standing pouch. However, although the standing pouch is of a deformable type, the pouch is provided with autonomy because it has a structure in which two ordinary standing pouches are connected side by side.

In addition, the appearance becomes unique and excellent, and when the contents are transferred, the contents can be stopped and put upright, so that the transfer operation can be easily performed.

[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 type of contents to be packaged and handling conditions such as handling 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
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.

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.
However, when laminating paper, it is preferable to laminate such that both sides thereof are sandwiched by a water-resistant or moisture-proof film such as a PET film, an ON film and a biaxially stretched PP film. When paper or synthetic paper is laminated, these are excellent in whiteness, so that the printing effect is enhanced and the design property can be improved. Further, when paper is laminated, the paper tends to be easily bent, so that the bending property at the heat seal portion in the vertical direction can be further 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.

A silica or alumina vapor deposition layer, an aluminum vapor deposition 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 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. As described above, the refill pouch of the present invention is a pouch in which the peripheral edge is heat-sealed in a bag shape and the content having fluidity is sealed and packaged, and the upper part of the pouch is constricted. The pouch is formed with a narrow width, and a cutout line for forming a spout for the contents is provided at the upper edge, and further, when the contents are poured out at the center of the pouch. A configuration in which a vertical heat seal portion for facilitating bending of the pouch is provided, and further, a configuration in which the perforated line is provided with easy-opening properties, and a lower portion of the pouch is provided on the pouch. It includes a configuration in which standing pouch-type bottoms are provided side by side on both sides of a vertical heat seal portion provided in a central portion.

Accordingly, the type of the pouch main body is not particularly limited as long as it does not cause a problem by providing a vertical heat seal portion in the center of the pouch, and any type can be used. For example, the pouch of the three-sided seal type, the four-sided seal type, or its deformation type, as well as the standing pouch type, is actually the deformation type as described above, but the vertical heat at the center of the pouch is used. The present invention can be suitably applied by forming a standing pouch-type bottom in parallel at the lower part of the pouch on both sides of the seal portion.

Then, according to the pouch type to be adopted, the heat sealing device, specifically, the seal pattern is changed using a bag making machine corresponding thereto, and a trimming device on the side of the pouch, and Notch, processing equipment for providing easy-open means such as half-cut line, that is,
A pouch can be easily manufactured by incorporating a punching device, a laser beam irradiation device, or the like in-line, or separately preparing it off-line.

FIG. 5 is a plan view showing a configuration of an embodiment 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. 1 are transferred to another container. It is. However, the shape of the pouch is shown at the time when it is close to the final stage of pouring. The refill pouch 100 shown in FIG.
It is configured as an application form of a four-sided seal type pouch, and the lower part of the pouch, that is, the bottom portion, is fixed to the lower edge of the laminated film 1 on both side walls in the same manner as a normal four-sided seal type pouch. The body is formed by heat sealing with a bottom seal portion 2 having a width, and the body portion has a shape in which both edges of both sides are curved from the middle to the top of the pouch 100 as shown in FIG. The upper part is formed by heat sealing with the side seal parts 3 and 3 having a narrow width, and trimming the outer side thereof, and is formed in a bag shape having an open upper part.

The upper seal portion 4 for sealing the upper part of the pouch
After the contents are filled through the upper opening, the contents are heat-sealed with a degassing seal or the like to be sealed. In this respect, the refill pouches 200 to 400 shown in FIGS.
The same applies to. And, when pouring out the contents from the lower end of the pouch 100 to the middle part of the central part of the pouch 100, that is, the central part of the laminated film 1 on the wall surface,
A vertical heat seal portion 6 for facilitating bending of the pouch 100 is provided, and a horizontal cutout line 7 is provided near the inside of the upper seal portion 4 along the side thereof. Are provided with notches 8,8.

The vertical heat seal portion 6 can be provided by, for example, heat sealing the side seal portions 3 and 3 at the same time. The cutout line 7 may be displayed only by printing, but in combination with the notches 8, 8, an easy-opening means such as a half cut line, a cut tape is attached, or a uniaxially stretched film is laminated. it can. Further, the notches 8, 8 may be provided only at one end of the perforated line 7.

By adopting such a configuration, since the refill pouch 100 is an application form of a four-side seal type pouch, there is no difference in film overlap, heat sealing is stable, and bag making is easy. At the same time, the contents can be easily filled from the upper opening. Further, the outer shape of the pouch is smart, similar to a container such as a bottle, and is excellent in design.

When using the contents, first,
The upper seal portion 4 at the top of the pouch is cut off along the perforation line 7 using the notch 8 and opened, and then, using the vertical heat seal portion 6 provided at the center of the pouch,
Initially, at the part corresponding to the extension, the upper part of the pouch is folded in two in the vertical direction, and as shown in FIG. 5, the opening is in the vertical direction, and the pouch 100 is gradually tilted and transferred. By pouring toward the mouth of 50, the width of the opening is substantially halved, and the width of pouring can be further reduced, so that the contents can be quickly and easily poured without spilling the contents outside. can do.

Then, the pouch 100 is gradually poured out so as to be folded down to the lower portion by the vertical heat seal portion 6 in accordance with the weight loss of the contents, so that the entire pouch 100 is reduced to a half width in the final stage. Therefore, 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.

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. The refill pouch 200 shown in FIG. 2 is different from the configuration of the refill pouch 100 shown in FIG.
It is configured by changing to a standing pouch type application form. That is, the bottom portion of the pouch 200 is formed in a gusset form in which the bottom film is folded inward and inserted between the lower portions of the laminated films 1 on both wall surfaces, and near the lower ends of both sides of the bottom film folded inward, Near the lower end of the central portion, bottom film cutouts 5, 5, 5a are provided, and the gusset portion into which the bottom film is inserted is placed on both sides of a vertical heat seal portion 6 provided at the center of the pouch, by standing pouches. The bottom seal of the type, that is, the bottom shape of the ship is heat-sealed with the bottom seal 2 provided in parallel, and the shape of the body by the side seals 3, 3 and the upper seal 4, the cutout line 7, the notches 8, 8 at the ends thereof, and the vertical heat seal portion 6 at the center of the pouch are all formed in the same manner as the refill pouch 100 shown in FIG. It is obtained by configuration Te.

The bottom film cutouts 5, 5,
Among the 5a, the bottom film cutout portion 5a near the lower end of the central portion can be omitted if it is not necessary for imparting independence to the pouch 200. Also in this case, the cut-out line 7 may be displayed only by printing, but in combination with the notches 8 and 8, furthermore, the half-cut line or the sticking of the cut tape, or the easy opening such as the lamination of the uniaxially stretched film. Notches 8, 8 may be provided only at one end of the perforated line 7.

By adopting such a configuration, the refill pouch 200 is easy to make a bag and fill the contents, and the pouch filled with the contents has autonomy.
In addition to being easy to handle, the appearance is unique and the design is excellent. And when using the contents,
As in the case of the pouch 100 for refilling shown in FIG. 1, the upper seal portion 4 on the upper portion of the pouch is cut off along the perforation line 7 using the notch 8 and opened, and then provided at the center of the pouch. At first, the upper part of the pouch is vertically folded in two at the portion corresponding to the extension line by using the heat seal part 6 in the vertical direction, and the opening is made vertical, and the pouch 200 is gradually inclined and transferred. By pouring toward the mouth of the container to be performed, the width of the opening is substantially halved, and the pouring width can be further reduced, so that the contents can be poured quickly and easily without spilling the contents. Can be issued.

Then, the pouch 200 is gradually poured out in such a manner that the pouch 200 is folded down to the lower portion by the vertical heat seal portion 6 in accordance with the decrease in the content, so that the entire pouch 200 is reduced to a half width in the final stage. Therefore, 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. Furthermore, the pouch 200 is self-supporting,
The pouring can be stopped halfway and placed upright, making the transfer operation even easier.

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. The refill pouch 300 shown in FIG. 3 is different from the configuration of the refill pouch 100 shown in FIG. 1 only in the vertical heat seal portion 6 provided at the center of the pouch as shown in FIG. From the lower end to the upper end, it is configured by changing to the shape provided for the entire length in the length direction, other configurations are
All are formed and configured similarly to the refill pouch 100 shown in FIG. Also in this case, the cut line 7
May be displayed only by printing, but in combination with the notches 8 and 8, an easy-opening means such as lamination of a half-cut line or a cut tape or lamination of a uniaxially stretched film can be used in combination with the notches 8 and 8. .

By adopting such a configuration, the inside of the refill pouch 300 is completely divided into two chambers by the vertical heat seal portion 6 provided at the center portion thereof, and a modified four-side seal type pouch is formed. Since it is a continuous packaging bag type that is arranged side by side, the width of each opening becomes narrower, and it becomes necessary to fill the contents separately from, for example, two head nozzles. The bending effect of the pouch 300 by the heat seal portion 6 can be further improved. In addition, the chambers on both sides of the pouch 300 are basically filled with the same contents, but if necessary,
Different contents can be filled in combination, and the advantage that the use range can be expanded in terms of application can be obtained.

When the same contents are filled in the chambers on both sides of the pouch 300, the upper seal portions 4, 4 on both sides are simultaneously cut out along the cutting line 7 by using the notches 8, 8 and opened. Then, similar to the refill pouch 100 shown in FIG. 1, the contents can be quickly and easily stored in another container in a similar manner to the method shown in FIG. Can be relocated. Further, when the chambers on both sides of the pouch 300 are filled with different contents, the upper seal portions 4 on both sides by using the notches 8, 8.
By dividing the side 4 separately on one side and cutting it along the cutting line 7, the dispensing method is slightly changed, but the contents can be quickly and easily transferred to another container.

FIG. 4 shows a fourth embodiment of the refill pouch of the present invention.
It is a top view which shows the structure of Example of this. The refill pouch 400 shown in FIG. 4 is different from the refill pouch 200 shown in FIG. 2 in that only the vertical heat seal portion 6 provided at the center of the pouch is replaced by the refill pouch shown in FIG. Like the pouch 300, the pouch is changed from the lower end to the upper end to have a shape provided over the entire length in the length direction, and all other configurations are the same as those of the refill pouch 200 shown in FIG. It is formed and formed.
Also in this case, the cutout line 7 may be displayed only by printing, but in combination with the notches 8, 8, a half-cut line or an easy-opening means such as laminating a cut tape or laminating a uniaxially stretched film is used in combination. can do.

Even when such a configuration is employed, the inside of the refill pouch 400 is completely partitioned into two chambers by the vertical heat seal portion 6 provided at the center thereof.
Since it is a continuous packaging bag type in which deformed standing pouches are arranged side by side, the width of each opening becomes narrower, and it becomes necessary to fill the contents separately from, for example, two head nozzles. The bending effect of the pouch 400 by the heat seal portion 6 in the vertical direction can be further improved. Also, in this case, the chambers on both sides of the pouch 400 are basically filled with the same contents. However, if necessary, different contents can be combined and filled. The advantage that can be expanded is obtained.

When the same contents are filled in the chambers on both sides of the pouch 400, the upper seal portions 4, 4 are simultaneously cut out along the cut line 7 by using the notches 8, 8, and opened. Refill pouch 1 shown in FIGS.
As in the case of 00 to 300, the contents can be quickly and easily transferred to another container in a manner similar to the method shown in FIG. When the chambers on both sides of the pouch 400 are filled with different contents, the upper seal portions 4 on both sides are separately divided one by one by using the notches 8, 8, and cut along the cut line 7. By cutting, the contents can be quickly and easily transferred to another container, although the pouring method is slightly different.

The refill pouch of the present invention as described above is formed with a narrow width in the shape of a constricted upper part of the pouch.
In addition, when the contents are poured out, the pouches are poured out in such a manner that the pouches are folded in two by a vertical heat seal portion provided at the center of the pouch. Therefore, the cutout line for forming the spout of the contents can be basically provided so as to cut out the entire edge of the upper part of the pouch, that is, the entire heat seal part in the upper part. In the refill pouches 100 to 400 shown in FIG. 4, they were provided in a horizontal straight line. However, the cut line is not necessarily limited to a horizontal straight line.
It can also be provided in a shape such as a letter shape.

In particular, when a vertical heat seal portion at the center of the pouch is provided over the entire length in the length direction of the pouch, and the inside is divided into two chambers, and the two divided chambers are filled with different contents. It is preferable that each upper part can be separately cut and opened, and for that, the cut line is
Rather than being provided in a horizontal linear shape, it is preferable to provide the above-mentioned V-shape or inverted V-shape in that the upper portions of both chambers are not accidentally cut off and opened at the same time. Furthermore, depending on the viscosity of the content to be filled and the size of the mouth of the container to be transferred, the cutoff line may be provided so as to cut off a part of the heat seal portion, not the entire heat seal portion on the top of the pouch, In that case, the cut line may be provided so as to partially cut out the central portion of the upper part of the pouch, for example, in a V-shape, and may also be formed by diagonally cutting the corners on both sides of the upper part of the pouch, that is, on both sides. And can be provided in a shape or the like that forms a C-shape.

[0048]

As described above, according to the present invention, there is no need for a separate spout made of a molded product or the like.
Can be manufactured with the same process as ordinary pouches with good productivity, easy to fill the contents, and the shape of the pouch is smart and excellent in design, especially when the shape of the pouch body is the application form of a standing pouch In addition, the pouch can be made self-sustaining, easy to handle, unique and excellent in appearance, and when transferring the filled contents to another container, the top of the pouch is easily cut along the line Can be cut and opened, and the contents are poured out while gradually folding the pouch vertically in two from the upper part to the lower part using the vertical heat sealing part provided in the center part of the pouch. It is possible to adjust the size of the opening appropriately, and even if the contents are relatively viscous, it can be quickly and easily transferred to the end without spilling outside.
