The present invention relates to a refilling pouch for sealing and packing contents having fluidity such as liquid, and transferring the contents to another container at the time of use, and more specifically, to the last in a small container such as a bottle. The narrow opening portion is provided in a part of the upper portion of the pouch so that it can be moved safely and easily, and the opening portion thereof is easily opened, and the opening property and the shape retention of the injection hole are improved so as not to be blocked in the middle of pouring. It is about a refillable pouch.

Conventionally, as a refilling pouch for sealing and packaging contents having fluidity such as liquidity, a standing pouch which is self-supporting and also has some of its features as a three-dimensional container is mainly employed, and is also used in another container without flowing the contents outward at the time of opening. In order to move safely, the opening is formed by cutting a part of the corner part and the like instead of the entire upper part of the pouch, or a part of the upper part of the pouch is provided with a narrow outlet part. The method of heat-bonding and attaching to a part of has been employ | adopted.

However, the opening of the pouch is not a whole of the upper part of the pouch but is formed by cutting a part of the corner part or the like. However, since the opening is not retained, the opening is likely to be blocked in the middle of pouring, and the pouch is pressed. When the contents are forcibly pushed out, the contents may be strongly spilled out and flow outward, and there is a problem in the ease and safety in carrying them.

In addition, the method of attaching a separate outlet of the plastic molded part to the upper part of the pouch has an increase in the manufacturing process, the cost of the outlet itself, and a problem of increasing the overall cost and complicated process and work. there was.

In addition, even in the method of providing a narrow outlet portion in the upper part of the pouch, the operability and safety when moving the contents to another container are somewhat improved, but the inlet portion of the outlet portion is difficult to open when the contents are ejected. In addition, since the shape retention of the openings is also reduced, there is a problem that the openings are likely to be blocked during pouring. Therefore, the method of providing the expansion part by the embossing method etc. is employ | adopted in addition to the film of the injection port part which narrowed the said width | variety. By this method, the opening and the shape retention of the spout are considerably improved, but it is necessary to have flexibility even if the pouch film itself is a laminated film, and depending on the handling of the pouch, the expansion portion provided in the spout is compressed. In some cases, it was necessary to improve the hardness and shape retention of the expanded portion.

The present invention is to solve such a problem, the object of the present invention is to produce a good productivity in the same process as a conventional pouch without the need for a separate injection port by molding or the like, easy to fill the contents In addition, by cutting a portion of the upper portion of the pouch during use, the inlet portion of the outlet portion is easily opened and its shape retention is improved, and the outlet portion is not blocked in the middle of dispensing. An object of this invention is to provide a refillable pouch having excellent usability for safely and easily carrying contents at low cost.

The above-mentioned subject can be solved by the following this invention. That is, the invention of Claim 1 is a pouch which consists of laminated | multilayer film, the peripheral edge part is heat-sealed in a bag shape, and the fluid content is sealed-packed, The said pouch has a spout part in a part of upper part, At the same time, the laminated film of the outlet portion is formed thicker than other portions, and at least the expansion film for improving the opening of the outlet is provided in the laminated film of the outlet portion, and a cut line is formed at the opening position of the outlet portion. It consists of a refill pouch characterized by the above-mentioned.

The perforation lines can be printed and displayed, for example, with lines, broken lines, and the like, and can be easily provided at the same time when printing a pattern or the like on the pouch. Moreover, even if it is not actually a line, it may be a symbol, a description, etc. which let a consumer recognize that it is cut off in the part. And the method of forming the laminated | multilayer film of the part in which the said injection port part is formed thicker than another part is not specifically limited, The following various methods can be employ | adopted.

For example, while extruding the resin of the sealant layer on the innermost surface of the laminated film by extrusion lamination, a film of the same material as that of the sealant layer is continuously formed in a band shape at the position of the upper portion of the pouch in which the spout is formed. I can make it thick. In addition, a film of the same material as the sealant layer may be supplied to the innermost surface of the laminated film to a portion where the ejection outlet portion is formed, heat sealed, laminated, and thickened. As another method, a polyester film or the like having good moldability can be thickened by continuous lamination or extrusion lamination in a band shape at a position on the upper portion of the pouch in which the ejection opening is formed. It may be.

Moreover, the said expansion part can be easily provided by a thermal embossing method, another hot press molding method, etc. And although this expansion part can also be provided only in one among the laminated | multilayer film of the wall surface of both sides of a pouch, by providing in both, the effect can be improved further.

By adopting such a configuration, the spout port is not provided in the whole of the upper part of the pouch but is provided in a part, and the opening can be narrowly formed by the perforation line so as to fit the dimensions of the inlet part of the container in which the contents are to be transported. In addition, at least the expanded film for improving the opening property of the ejection outlet is provided in the laminated film of the ejection outlet portion, and furthermore, at least the laminated film of the portion is formed thicker than other portions, so that the hardness of the expanded portion is increased. And prosthesis is improved. Thus, when the contents are transferred to another container, the narrow outlet portion is easily opened by cutting a portion of the upper portion of the pouch along the perforation line. In addition, since the open ejection outlet is excellent in shape retention, the ejection outlet can be safely and easily moved to the end without being blocked during the ejection.

Moreover, since the thickness of the laminated film of the pouch wall surface is not thickened as a whole, it is made thick at least only to the part in which the injection-out part is provided, and can raise a cost. In addition, in the case where the portion of the laminated film having a thick thickness is used as an area of the upper portion of the pouch including the spout, the rigidity of the laminated film of the portion is increased, and thus, the shape of the pouch opening (filling hole) during the filling of the contents. Can be stabilized, the workability of filling can be improved, and the form of the upper portion of the pouch after filling can be stabilized.

The invention described in claim 2, wherein the spout portion is formed in a part of the upper portion of the pouch in a narrow width by a heat-sealing portion of the outer periphery, and a cutout portion is formed on both sides of the spout portion to protrude. It consists of the refill pouch of Claim 1 characterized by the above-mentioned.

By adopting such a configuration, in addition to the operation and effect of the invention described in claim 1, since the narrow outlet portion provided in a part of the upper portion of the pouch is protruded outward by the cutouts on both sides, the contents can be transferred to another container. At this time, the ejection outlet can be ejected by being inserted into the inlet of the container, so that the fixing property is good and the contents can be moved more safely.

The invention described in claim 3 is a refill pouch according to claim 1 or 2, wherein an opening facilitation means is provided in the outlet portion.

The easy opening means is a method of laminating a uniaxially stretched film in a laminated film of a half cut line by laser light irradiation or the like, in addition to a notch which is also widely used as a normal pouch, or a cut tape or a pouch (in this case, The uniaxial stretched film is used so that the stretching direction coincides with the opening direction of the ejection outlet portion), and these may be used alone, or, for example, adhesion of the notch and the half cut line, or the notch and the cut tape, or It can also use combining suitably, such as lamination | stacking of a notch and a uniaxial stretched film.

When providing a half cut line, it is not limited to a straight half cut line, It can also provide as an intermittent half cut line, such as a sewing line shape. In addition, although there may be one such half cut line, assuming that the cutting direction is shifted, a plurality of half cut lines, such as one or each two, are parallel or centered on both sides of the center half cut line. It may be arranged to converge to the cut line. As the notch, a single or V-shaped notch is usually used, but the shape is not particularly limited, and any shape can be used as long as it has a sharp part in the cutting direction.

By adopting such a constitution, in addition to the operation and effect of the invention according to claim 1 or 2, when opening the ejection outlet, a tool such as scissors is not required, and is easily cut and opened at a desired position with only a hand. can do.

The invention described in claim 4 is a refill pouch according to any one of claims 1 to 3, wherein the pouch is a pouch in the form of a standing pouch.

By adopting such a configuration, in addition to the action and effect of the invention according to any one of claims 1 to 3, the pouch is provided with independence, and in particular, handling of the pouch after the contents are filled, as well as appearance Also, since the contents can be stopped and stopped in the middle when the contents are moved, the operation of moving the contents can be performed more easily.

<Embodiment of design>

EMBODIMENT OF THE INVENTION Below, embodiment of the invention, such as the manufacturing method of the laminated | multilayer film and pouches used for the refilling pouch of this invention, is demonstrated. Although the laminated | multilayer film mainly made of plastic is used for the laminated | multilayer film used for the refilling pouch of this invention, it is not specifically limited, For example, all the well-known laminated | multilayer film used for various liquid pouches can be used, Among them, a suitable one can be freely selected and used according to the use conditions such as the type of the contents to be packaged and the handling after filling.

(13) PET film / adhesive / EVOH film / adhesive / ON film / adhesive / CPP film (sealant layer)

Although these etc. are mentioned, It is not limited to these, A laminated film of various combination can be used. In addition, in the structure of each laminated film mentioned above, the structure which forms at least the laminated film of the part in which the spout part is formed, ie, the part in which the expansion part is formed in the spout part is formed thicker than another part, was described, but the thickness is partially The method of increasing itself is as described above, and when the thickness is increased by the film of the sealant layer, for example, the resin of the sealant layer is further compressed into a film form on the sealant layer of each of the above laminated films by extrusion lamination. While the film of the sealant layer is partially polymerized and crimped and cooled thereon, the desired laminated film can be continuously produced.

In the above-described configuration, the ON film is a biaxially stretched nylon film, LLDPE is linear low density polyethylene, HDPE is a high density polyethylene, LDPE is a low density polyethylene, PP film is a polypropylene film, and PET film is a biaxially stretched polyethylene The terephthalate film, the EVOH film, and the ethylene-vinyl acetate copolymer saponified film, and the CPP film, represent an unstretched polypropylene film. In addition, an anchor coat is a kind of primer coat which coats on the base film side previously, in order to improve adhesiveness when laminating resin by extrusion coating.

In the structure of the laminated | multilayer film seen from above, ON film and PET film of outermost layer provide a mechanical strength and printability to a pouch as a base film, and the uniaxially stretched HDPE film and uniaxially stretched PP film of an intermediate | middle layer are the extending | stretching The film which uses a direction so that it may coincide with the cutting direction at the time of opening the pouring-out part of a pouch, can cut | disconnect cutting direction as one of easy opening means. In addition, when a perforation line is a diagonal direction etc., it is preferable to use a biaxially stretched HDPE film or a biaxially stretched PP film as an intensity | strength and a moisture permeability improvement layer. The ON film used for an intermediate | middle layer is for improving strength.

And a silica or alumina vapor deposition layer, an aluminum vapor deposition layer, an aluminum foil, EVOH film, etc. are laminated | stacked in order to provide gas barrier property. In addition, although two types of examples of the L.LDPE film and the CPP film are mentioned as the sealant layer, the L.LDPE film has excellent heat sealing stability and resistance to contents, for example, stress cracking resistance to a surfactant, and the like. , CPP film has excellent heat resistance and low odor, and is suitable for packaging of contents requiring such performance.

In addition to the sealant layer, an ethylene-α-olefin copolymer, an ethylene-vinyl acetate copolymer, an ethylene-acrylic acid copolymer, an ethylene-acrylic acid ester copolymer, an ionoma, a polyester-based resin, etc. may be appropriately selected and used in the sealant layer. have.

In particular, the polymerization of a ethylene-α-olefin copolymer using a single-site catalyst such as a metallocene catalyst has a narrow molecular weight distribution and a stable copolymerization ratio, which is excellent in low temperature heat sealability and hot sealability, and thus standing pouches. It is suitable for the sealant layer of the pouch with the step difference due to the difference of the overlap of the film in the heat sealing portion as described above, in that pinholes due to missing seals can be prevented. Moreover, by using the thing which mixed the said olefin type elastomer with the said copolymer, the heat fluidity | liquidity of a sealant layer improves and pinhole generation by the said step can be prevented more effectively.

Next, the manufacturing method of the refill pouch of this invention manufactured using the above laminated | multilayer film is demonstrated. The shape of the main body portion of the refill pouch of the present invention is not particularly limited. For example, a gusset pouch or the like can be used in addition to the pouches and standing pouches of the three-way closure type and the four-way closure type. According to the type of pouch to be employed, using a corresponding pouch maker, each opening means such as notches, cutouts, notches, half-cut lines, etc., and expansion portions provided on the laminated film on the wall of the pouch are used. In addition to processing devices for processing additional components, ie trimming devices, punching devices, heat seal devices, laser light irradiation devices, embossing devices or hot press forming devices, etc. in-line to the pouch maker, or off By separately preparing as a line, a pouch can be easily manufactured.

Moreover, the shape of the expanded part provided in the laminated | multilayer film of the said wall surface is not specifically limited, It can provide in arbitrary shapes, such as the planar shape and the cross-sectional shape of a height direction. That is, the expanded portion in the spout can be any shape that facilitates the opening of the spout and facilitates the shape retention, and can be provided in any shape as long as it is suitable for the purpose. For example, the planar shape can be arbitrarily provided in a shape along the shape of the spout, or in a shape symmetrical with respect to the centerline of the spout, or asymmetrical. Moreover, also about the cross-sectional shape of a height direction, it can be provided in arbitrary shapes, such as a trapezoid and the shape of the trapezoid of big and small, overlapping in two steps, a semicircle, a semi-ellipse, and a triangle.

Although this expansion part may be provided only in the spout part, it may further extend so that it may extend to reach the center of a pouch or the lower part of a pouch, for example. However, in the case of providing it long, the lower part other than the spout part has little relation with the opening property, and on the contrary, an effect of widening the pouch to the outside by the bending effect and facilitating the flow of the contents to the spout part can be obtained. .

<Example>

Hereinafter, the present invention will be described in more detail with reference to the drawings. However, the present invention is not limited to these drawings. 1 to 7 are plan views showing the configuration of one embodiment of the refill pouch of the present invention, respectively. 8 is a sectional view taken along the line A-A of the refill pouch shown in FIG. 1, and is a diagram showing an example of the cross-sectional shape of the expanded portion provided in the laminated film of the pouring port of the pouch.

However, it is a figure at the time of providing an expansion part symmetrically in the position which the laminated | multilayer film of both sides overlap.

As for the refill pouch 100 shown in FIG. 1, the main-body part is manufactured in the form of a standing pouch. That is, the bottom part is formed in the gusset form which folded the bottom film inwardly between the laminated | multilayer film 1 of the wall surfaces of both sides, and in the case of FIG. 1, the semicircular bottom film cutout is provided in the vicinity of the lower end of both sides of the bottom film folded inwardly. Couplings 5 and 5 are provided. In addition, a gusset is formed by heat sealing in the bottom bottom sealing part 2 of the bottom type, and the heat in the side sealing parts 3 and 3 of both edges of the laminated film 1 of both wall surfaces is formed. The body part is formed by suture.

Moreover, in the part 6 which thickened the thickness of the upper laminated | multilayer film among the laminated | multilayer film 1 of the said both wall surfaces, the film of the same material as a sealant layer is added to the innermost layer, and laminated | stacked, It is formed thicker than the part, that is, the lower part. In this case, the area | region of the part 6 which thickened the said laminated | multilayer film can be made small in the shape except the part of the upper suture part 4 of the upper part, By this structure, the upper suture part 4 The sealing conditions at the time of heat-sealing) can be alleviated. Then, at one corner portion of the upper portion of the pouch 100, a cutout line 7 for forming the spout 10 is provided by printing, and the notches 8 and 8 are provided at the ends of both sides thereof. At the same time, an expansion section S for improving the opening of the ejection opening is provided in the ejection opening so that the cutout line 7 and a part thereof cross each other.

By adopting such a shape, the resistance against compression of the inflated portion S can be strengthened, and the portion where the inflated portion S is provided, that is, the laminated film on the upper portion of the pouch in which the spout is formed, is formed thicker than other portions. Since the expansion portion S formed in this portion is increased in rigidity, the resistance against compression, that is, the shape retention can be further improved. Such expansion part S can also be provided only in one laminated film.

In addition, although the cutting line 7 is sufficient only by the display by printing, in combination with the notches 8 and 8, it can provide easy opening means, such as a half cut line by laser beam irradiation etc. in this part. In addition, the upper sealing part 4 which seals the upper part of the pouch 100 is made into the unsealed opening before filling the contents, and is sealed by heat sealing by degassing sealing etc. after the contents are filled from this part. This point is the same also about the refill pouch shown to the following FIGS.

The refilling pouch 600 shown in FIG. 6 is a shape which, in the configuration of the refilling pouch 100 shown in FIG. 1, faces the shape of the spout 10 at a widthwise widthwise direction by a heat-sealing portion of its outer periphery. And cutout portions 9a and 9b on both sides thereof, and change to a shape projecting in the transverse direction, and at the same time, the cutout line 7 is substantially perpendicular to the inner side of the heat sealing portion at the tip of the spout 10. Direction, and changed to the shape which provided the notch 8 in the upper end part, Furthermore, as shown, the expansion part S provided in the injection outlet part respond | corresponds to the injection outlet part in the vicinity of the injection outlet part. The width and height are large in the lateral shape, and the width and height are connected at the same angle toward the center of the pouch from there, and the angle is changed from the pouch center to the inclined downward direction. Ha It will be configured. In addition, the cross-sectional shape of the height direction of the said expansion part S is formed in the shape which piled up trapezoid in two steps, as shown to the sectional line A-A of FIG.

By adopting such a configuration, first, the point of providing the ejection outlet portion 10 in a shape that protrudes in the lateral direction in a narrow width is not provided with the ejection outlet portion and the handle portion of the refill pouch 500 shown in FIG. Other than that, it is the same structure and can acquire the effect similar to the effect demonstrated by FIG. Then, as described above, the expanded portion S is shaped to reach the stop portion of the pouch inclined downward from the spout 10 through the center portion of the pouch, and the cross-sectional shape is a two-step trapezoid. By providing a shape that is stacked in the shape of the stack, the rib portion is excellent in the rib effect due to the bending line of the stepped portion, the resistance to compression is increased, and it is easy to recover even once compressed, and the shape retention is excellent. Done. Therefore, the expanded portion S of the spout portion further improves the opening and the shape retention of the spout portion, and the lower portion S following the spout portion fills the contents by the rib effect and the bending effect. It improves the shape stability of the subsequent pouch, and at the time of discharging the contents, the contents are easily flowed into the dispensing outlet. In addition, since the structure other than the said change is the same as that of the refilling pouch 100 shown in FIG. 1, the effect similar to the operation effect demonstrated by the refilling pouch 100 can be obtained.

7 is a plan view showing the configuration of a seventh embodiment of a refill pouch of the present invention. In the configuration of the refilling pouch 100 shown in FIG. 1, the refilling pouch 700 shown in FIG. 7 is configured by changing only the type of the pouch body from a standing pouch type to a pouch of all-sea closure type. All are configured similarly to the refill pouch 100 shown in FIG.

When the pouch body is formed in a four-sided seal form, the pouch loses its independence and is slightly inferior in terms of ease of handling and appearance of the pouch after filling the contents. However, the pouch is easy to manufacture, has high productivity, and can be manufactured at low cost. You can get this. In addition, since the other structure is the same as that of the refill pouch 100 shown in FIG. 1, the effect similar to the operation effect demonstrated by the refill pouch 100 shown in FIG.

Hereinafter, also about the refilling pouch shown to FIG. 2-FIG. 6, only the form of the pouch main body can be changed into the all-sealing form, and can be comprised. And even in such a case, the above-mentioned gains and losses are caused by changing the pouch form from the standing pouch form to the all-sea closure form, but in other respects, it is the same configuration as the refill pouch shown in FIGS. 2 to 6, respectively. The same effect can be obtained as described above.

As described in detail above, according to the present invention, it does not require a separate ejection outlet by a molded product or the like, and can be manufactured with good productivity by the same process as a conventional pouch, and the filling of the contents is easy, and the pouch body In the case of the stand-up pouch type, the pouch has added self-reliance, is easy to handle, has excellent shape stability and appearance, and, in use, can easily be cut off at the tip of the spout provided at the upper part of the pouch. It can be opened, and thus the ejection outlet having excellent shape retention is automatically opened so that the ejection outlet is not blocked in the middle of ejection, and even for containers such as bottles with small calibers, the end is safely and easily closed. Refillable pouch with excellent usability that can be transported to at low cost There is the effect that good dispersibility can be provided.
