  The present invention relates to a pouch container with a spout on which a nonwoven fabric layer is laminated.

Conventionally, as a container for filling beverages, jelly-like foods, and the like, a pouch container with a spout in which a spout for filling filling is attached to the upper part of a bag body made of a flexible film is known. Such a pouch container with a spout is often chilled after filling with a beverage or the like. However, when the filled pouch container is cooled in this way, it is cold when it is held by hand, and condensation is formed on the bag surface or the temperature of the filling is increased. In particular, when a beverage is filled with ice, or iced confectionery such as ice cream or ice cream is used as a filling, not only is it very cold and condensation is likely to occur, but the filling is accelerated. Melt.
In view of such a point, the present applicant has proposed a pouch container with a spout in which a foamed resin layer is laminated (Japanese Patent Laid-Open No. 2001-130586). Such a pouch container is very preferable since heat insulation can be imparted by the foamed resin layer, but further, a pouch container with a spout having heat insulation by different means is desired.

Since the nonwoven fabric layer is provided in the laminated film which comprises the bag main body, the said pouch container with a spout is excellent in the heat insulation effect. Therefore, even if the filling is cooled or warmed, it is difficult for the temperature of the filling to be transmitted to the hand, and the filling is kept cool and warm.

Furthermore, the second means of the present invention is a pouch container with a spout in which a spout is attached to a bag body formed in a bag shape by overlapping and heat-sealing the end portions of the laminated film, Provided is a pouch container with a spout, in which a nonwoven fabric layer is laminated on an intermediate layer of the film, and the filaments of the nonwoven fabric layer are made of filaments having surface heat-fusibility.
In the above-mentioned pouch container with a spout, the nonwoven fabric layer is made of a surface heat-fusible filament. Therefore, when the end of the laminated film is heat-sealed to form a bag body, the heat melts the filament. Therefore, the filament does not rise from the edge of the heat-sealed part of the bag body, and a pouch container having a beautiful appearance can be provided, and water can be prevented from penetrating into the nonwoven fabric layer through the edge of the heat-welded part. can do.

  According to the pouch container with a spout of the present invention, since it is excellent in heat insulation, even if it is cooled or warmed, the temperature of the filling is difficult to be transmitted to the hand, and the coldness or heat retention of the filling is also excellent. Can be provided. Furthermore, the filament of the nonwoven fabric does not come out from the end of the film, so that a beautiful pouch container can be obtained, and water can be prevented from entering the nonwoven fabric layer.

  In a preferred embodiment of the pouch container with a spout of the present invention, a spout is attached to a bag body formed in a bag shape by heat-sealing at least end portions of the front and back pieces, and the front and back pieces are attached to an intermediate layer. It consists of a laminated film provided with a nonwoven fabric layer. Moreover, the preferable one aspect | mode of the pouch container with a spout of this invention is provided with the space | gap layer which has a vent hole in addition to the nonwoven fabric layer in the laminated film which comprises a bag main body. The vent is preferably opened at the upper edge or / and the lower edge of the bag body, and in particular, the vent is preferably opened at the upper edge. Furthermore, in a preferred embodiment of the pouch container with a spout of the present invention, the spout is attached to a bag body formed in a bag shape by heat-sealing at least the end portions of the front and back pieces, The bag body is constituted by a single laminated film provided with a non-woven fabric layer as a layer, and this film is folded and both end portions are heat-sealed.

Hereinafter, the present invention will be specifically described with reference to the drawings. For convenience, as a term indicating a direction, “inside” refers to the direction of the storage portion in which the filling is filled, and “outside” refers to a direction away from the storage portion.
In FIG. 1 to FIG. 3, reference numeral 1 denotes front and back pieces 5 and 5 in which a nonwoven fabric layer 55 is provided in an intermediate layer and a void layer 2 is provided facing the nonwoven fabric layer 55, and side gusset portions. A pouch container with a spout is shown in which a spout 8 is attached to a bag body 7 composed of both side face pieces 6 and 6 constituting the same. Such a pouch container 1 with a pouch is a self-supporting pouch in which, after filling, the bottom portions 1a for placing are formed by folding back the lower portions of the front and back surface pieces 5 and 5.

The bag body 7 is composed of four flexible film pieces, a front piece 5, a back piece 5, and both side pieces 6, 6, and is formed into a bag shape by bonding the inner surfaces of the end portions of the pieces 5, 6 together. Is formed. Specifically, the front and back pieces 5 and 5 are formed in a shape in which both lower corners of a rectangular laminated film are cut in an inclined manner in order to improve the self-supporting stability of the bottom face 1a formed after filling. On the other hand, the side surface pieces 6 and 6 are shaped along the side end portions 5a and the inclined side end portions 5b of the front and back surface pieces 5 and 5, and are folded inward in the vertical direction at the center portion. A predetermined width (for example, about 4 to 10 mm) is obtained by overlapping the inner surfaces of the side end portion 5a and the inclined side end portion 5b of the front and back piece 5 with the inner surfaces of the side end portion 6a and the inclined side end portion 6b of the both side surface pieces 6. The heat-sealed portion 4 is formed by heat-sealing, and the inner surfaces of the lower end portions 5c of the front and back surface pieces 5 are overlapped and heat-sealed by a predetermined width, so that an upper-opening bag body 7 is formed. . Then, in the pouch container 1 with a spout, the conduit 81 of the spout 8 is inserted into the storage portion 71 of the bag body 7 from the upper opening, and the spout is placed between the upper end portions 5d of the front and back pieces 5 as shown in FIG. By sandwiching the 8 fusion-bonded portions 82, the inner surfaces of the upper end portions 5d of the front and back surface pieces 5, and the inner surface of the upper end portion 5d and the peripheral surface of the fusion-bonded portion 82 are heat-sealed by a predetermined width. Is formed.
The spout 8 includes a spout to which a removable cap is attached and a fusion-bonded portion 82 that is an attachment portion to the bag body 7, and the material thereof is made of various synthetic resins, metals such as aluminum, and the like. However, since it can be easily attached to the bag body 7, it is preferable that at least the peripheral surface of the bonded portion 82 can be heat-sealed with the inner surface of the front and back piece 5, for example, synthesis of polyethylene, polypropylene, or the like. A material of the same kind as the sealant layer 51 of the front and back piece 5 is preferable because it can be formed by a resin molded product and can be heat-sealed well.

The front and back pieces 5 and both side pieces 6 are each composed of a laminated film obtained by laminating a plurality of films including a nonwoven fabric, but the front and back pieces 5 are provided with a gap layer 2 in the middle of the laminated film. ing. Specifically, as shown in FIG. 3, the front and back surface pieces 5 are, for example, in order from the inner side toward the outer side, for example, a sealant layer 51 for heat-sealing, and bag strength (bending resistance, pinhole resistance). Etc.), a barrier layer 53 for imparting gas barrier properties and light shielding properties, a release layer 54 for forming a void layer 2 into which air flows, a nonwoven fabric layer 55 made of nonwoven fabric, An outer surface layer 56 for imparting surface friction and heat resistance is laminated.
The sealant layer 51 is not particularly limited as long as it is a heat-sealable material. For example, polyethylene such as high-density polyethylene and linear low-density polyethylene, polypropylene, ethylene-vinyl acetate copolymer, and the like can be used. . Of these, it is preferable to use a linear low-density polyethylene film having excellent heat-fusibility. The thickness of the sealant layer 51 is, for example, about 30 to 150 μm. The base material layer 52 is not particularly limited as long as it is relatively excellent in strength, such as polyamide film such as nylon, polyester film such as polyethylene terephthalate, polypropylene film such as polypropylene and propylene-ethylene copolymer, and the like. A synthetic resin film, synthetic paper, two or more kinds of laminates, and the like can be used. Of these, it is preferable to use polyamide-based films such as 6 nylon and 6, 6 nylon, which are excellent in bending resistance. The thickness of the base material layer 52 is, for example, about 10 to 70 μm. The barrier layer 53 is not particularly limited as long as it has a gas barrier property, and a synthetic resin film having a gas barrier property such as a metal foil such as aluminum, polyvinylidene chloride, and an ethylene-vinyl alcohol copolymer. A laminate or the like can be used. Among these, it is preferable to use a metal foil such as aluminum because it also has a light shielding property. The thickness of the barrier layer 53 is, for example, about 6 to 30 μm in the case of aluminum foil. In some cases, the gas barrier property may not be necessary depending on the filler, and therefore the barrier layer 53 may be omitted depending on the case.
The release layer 54 is provided, for example, by applying a release agent such as silicone or polyamide nitrified cotton-based resin coating agent on the outer surface of the barrier layer 53 by a gravure printing method or the like. In the range where the release layer 54 is provided, the barrier layer 53 and the non-woven fabric layer 55 are not bonded even if lamination is performed, and the void layer 2 is formed between the layers 53 and 55. Although the range in which the peeling layer 54 is provided is not particularly limited, it is preferably provided in as wide a range as possible from the viewpoint of further increasing the heat insulating effect by making the gap layer 2 a large area. However, if the release layer 54 is provided over a wide range, the nonwoven fabric layer 55 (outer film layer) may be inadvertently peeled off. If the release layer 54 is provided along the edge of the barrier layer 53, the edge of the nonwoven fabric layer 55 may be removed. For example, the peeling layer 54 is preferably provided in a range excluding the heat-sealed portion 4 of the bag body 7, and the bottom surface 1 a configured after filling is expanded by the gap layer 2. Therefore, it is preferable that the peeling layer 54 is provided in a range excluding the bottom surface forming portion of the front and back surface pieces 5 as shown in the drawing.
Furthermore, a part of the peeling layer 54 is provided so as to extend to the edge of the barrier layer 53, and the air vent 3 communicating with the gap layer 2 and the outside is formed at this edge. The peeling layer extending portion 54a is preferably extended to the upper end portion 5d side of the front and back piece 5 as shown in the drawing from the point that dust adhesion can be surely prevented.

As the nonwoven fabric layer 55, a nonwoven fabric produced by forming a sheet of polyester, polypropylene, polyethylene, rayon, nylon, cupra, natural fiber, or the like into a sheet by an adhesion method, a needle punch method, a spun bond method, a melt blow method, or the like is used. it can. Among them, since it is melted by heat at the time of forming the heat fusion part 4, at least the surface uses a fiber having a heat fusion resin such as polyethylene such as high density polyethylene and linear low density polyethylene, and polypropylene. Is preferred. As such fibers, for example, solid fibers or hollow fibers made of a heat-fusible resin such as polyethylene, or a heat-fusible resin 92 is coated around the core material 91 as shown in FIG. Among them, the core material 91 is relatively excellent in strength, such as polyamide fiber such as nylon, polyester fiber such as polyethylene terephthalate, etc. Is preferably a heat-fusible conjugate fiber in which a heat-fusible resin 92 such as linear low-density polyethylene is coated. Examples of such a heat-fusible filament 9 include trade name Elves (manufactured by Unitika Ltd.). The fiber length is preferably a long-fiber non-woven fabric sheet in terms of strength due to a three-dimensional network structure formed by entanglement of fibers and the handleability of the sheet, and a short-fiber non-woven fabric is preferable in terms of sheet cutting suitability. As the physical properties of the nonwoven fabric sheet, for example, the basis weight is preferably about 10 to 100 g / m ² (preferably 15 to 50 g / m ² ), the thickness is about 10 to 100 μm, and the denier is about 1 to 5 d.

  As the outer surface layer 56, for example, a polyester film such as polyethylene terephthalate, a polyamide film such as polypropylene and nylon, two or more laminates, and the like can be used. In the case of a synthetic resin film, a stretched film is used. It is preferable. Of these, it is preferable to use a polyester film such as polyethylene terephthalate which is excellent in heat resistance, dimensional stability and the like at the time of heat fusion. The thickness of the outer surface layer 56 is, for example, about 10 to 70 μm. Although not particularly illustrated, design printing on which an indication of a product name, a pattern, or the like is printed is performed on the inner surface or the outer surface of the outer surface layer 56. When the design printing is performed on the inner surface, the outer layer 56 Transparent material is used.

Each of the above layers is preferably dry lamination using an adhesive, but can also be laminated by a known laminating process such as thermal lamination in which a heat-sensitive adhesive is sandwiched. As the barrier layer 53, a metal foil such as aluminum or a vapor deposition layer such as silicon oxide can be laminated. Specifically, a linear low density polyethylene film 51 is laminated on the inner surface of a nylon film 52 on which a barrier layer 53 made of polyethylene terephthalate film deposited with silicon oxide is laminated by dry lamination, extrusion lamination, etc. A laminated film constituting the front and back piece 5 is obtained by applying a release agent 54 to a predetermined range of the outer surface of the polyethylene terephthalate film 53 and laminating the nonwoven fabric 55 and the design-printed polyethylene terephthalate film 56 sequentially by dry lamination or the like. Is formed.
The side piece 6 has the same configuration as the front and back pieces 5 except that no release layer is provided. For example, as shown in FIG. Linear low density polyethylene) / base layer 62 (nylon) / barrier layer 63 (polyethylene terephthalate film deposited with silicon oxide) / nonwoven fabric layer 65 (nonwoven fabric made of heat-fusible fibers) / outer surface layer 66 (polyethylene terephthalate) ) Is a laminated film in which each layer is laminated.

The pouch container 1 with a spout can be manufactured by the following method, for example.
As shown in FIG. 5 (a), the side film original fabric sheet 26 is folded between the surface film original fabric sheet 25 in which the surface pieces 5 are continuously connected in the vertical direction and the back film original fabric sheet 25. While sandwiching, in order to form the heat-sealed portion 4 (shown by hatching) shown in FIG. 5 (b), using a heat sealing device, a hot plate is applied from the top and bottom of the front and back film original sheets 25, 25, The inner surfaces of the sealant layers 51 and 61 of the original fabric sheets 25 and 26 are heat-sealed. Thereby, the bag continuous body 27 which the bag main body 7 connected continuously as shown in FIG.5 (b) is obtained. Then, after cutting this bag continuous body 27 and producing each bag main body 7, the spout 8 may be attached. However, the bag continuous body 27 is wound into a roll shape, and then this bag continuous body roll 30 is Attached to the spout attachment device installed in the filling line, while feeding the bag continuum 27 from the bag continuum roll 30, it is cut along the planned cutting line X (two-dot chain line shown in FIG. 5B), and the upper opening type The top and bottom pieces 5 and 5 are sucked by vacuum to open the upper end 5d, the spout 8 is inserted from here, and the upper end 5d is heated while sandwiching the fused portion 82. After obtaining the pouch container 1 with a spout by fusing, the filling material is filled through the spout 8 of the spout 8, and the cap is screwed into the spout to produce a filled pouch container with a spout. Can do.

Since the nonwoven fabric layer 55 is laminated | stacked on the front-and-back surface pieces 5 and 5 and the both-side surface pieces 6 and 6 which comprise the bag main body 7, the said pouch container 1 with a spout has a heat insulation effect. Therefore, even if the filling is cooled or warmed, the temperature is not easily transmitted to the hand, and the filling is kept cool and warm. Further, when the non-woven fabric layer 55 is laminated, the non-woven fabric filaments randomly appear from the edge (cut edge) of the laminated film. In the present invention, the non-woven fabric layer 55 is composed of the thermally fusible filament 9. The filament 9 is melted by heat when the end portions of the front and back surface pieces 5 and the both side surface pieces 6 are heat-sealed, so that the nonwoven fabric filament 9 does not fluff from the cut edge 55a of the nonwoven fabric layer 55, and dust or the like is generated. Since it is difficult to adhere, a beautiful end treatment can be performed. In addition, since the filament 9 is melted in the heat-sealing portion 4 in this manner, the space (gap) between the filaments in the cut end portion 55a is almost eliminated, so that the non-woven fabric layer 55 is cut from the cut end portion 55a. It is possible to prevent water from penetrating into the layer 55. Further, if the vent hole 3 is not formed, the entrance to the gap layer 2 from the outside is closed, so that there is no problem even if the filled pouch container is sterilized by retort, for example.
Further, since the void layer 2 having the vent 3 communicating with the outside is provided facing the nonwoven fabric layer 55, sufficient air enters the nonwoven fabric layer 55 and the void layer 2, and the heat insulation effect is further enhanced. In addition, for example, if the filling is iced using a conventional pouch container, the outer shape of the solidified filling is reflected on the outer surface of the bag body, and the pouch container has a rugged appearance. By providing the gap layer 2 in the intermediate layer of the front and back pieces 5 as in the invention, the shape of the solidified filler is difficult to be reflected, and thus a pouch container 1 that exhibits a natural smooth appearance even when the solidified filler is added. Can provide.
Further, since the vent 3 is opened at the upper end portion 5d, it is possible to prevent dust from adhering during manufacture and distribution. That is, when an opening is provided in the bag, dust or the like easily adheres to the edge of the bag. By providing the vent 3 in the upper end 5d as described above, in the state of the continuous bag roll 30 at the time of manufacture. Since the vent 3 is not opened, there is no possibility that dust or the like will adhere when the bag continuous body roll 30 is stored and transported. In addition, after filling the pouch container 1 with a spout, the upper end portion 5d to which the spout 8 is attached does not come into contact with the transport conveyor, the packing box, or the like, so that dust or the like hardly adheres to the vent hole 3. There is. The vent 3 is preferably provided on both sides of the spout 8 except for the position where the spout 8 is heat-sealed.
Furthermore, since the means for forming the void layer 2 is to provide the release layer 54 in the middle of the laminated film, the desired void layer can be obtained simply by adhering the film coated with the release layer 54 by a known laminating process. 2 can be formed. That is, when the laminated film constituting the pouch container 1 is manufactured, the gap layer 2 can be secured only by adding the step of applying the release layer 54 to a desired range, and the others are manufactured in the same procedure as before. Therefore, the pouch container 1 of the present invention can be manufactured using an existing manufacturing line.

The present invention is not limited to the above-described embodiments, and can be modified, substituted, replaced, added, and the like. Hereinafter, parts different from those of the above embodiments will be mainly described, and the same configuration may be referred to using terms and figure numbers, and the description thereof may be omitted.
In each said embodiment, although the nonwoven fabric layer 55 is provided in both the front and back piece 5 and the both-side pieces 6, the nonwoven fabric layer 55 may be provided only in the front and back piece 5, for example. This is because a heat insulating effect can be expected if at least the nonwoven fabric layer 55 is laminated on the front and back surface pieces 5 occupying a wide area of the bag body 7.
The lamination position of the nonwoven fabric layer 55 is not limited to between the barrier layer 53 and the outer surface layer 56, and is provided, for example, between the base material layer 52 and the barrier layer 53, between the sealant layer 51 and the base material layer 52, and the like. It may be. However, when the vent 3 is provided, it is preferable that the non-woven fabric layer 55 is provided outside the barrier layer 53 because the outside air flows into and out of the nonwoven fabric layer 55 through the vent 3. Further, if the nonwoven fabric layer 55 is laminated facing the sealant layer 51, the filament 9 of the nonwoven fabric layer 55 adheres to the sealant layer 51 in the heat fusion part 4 due to heat at the time of thermal fusion. This is preferable because fuzz of the filament 9 can be prevented more reliably. In this case, the heat-fusible filament 9 constituting the nonwoven fabric layer 55 is preferably made of the same material as at least the surface of the sealant layer 51.

  Further, in each of the above embodiments, the gap layer 2 and the vent hole 3 are provided only on the front and back pieces 5, but the gap layer 2 may be provided by laminating the release layer 55 on both side pieces 6. Moreover, the aspect in which the space layer 2 and the vent hole 3 are not provided in the front and back piece 5 may be used. In the case where the gap layer 2 is provided on the front and back piece 5 and / or the side piece 6, the range where the release layer 54 (gap layer 2) is provided includes the heat fusion part 4 and the bottom face forming part as described above. Although it is most preferable to be provided in the excluded range, the present invention is not limited to this. For example, as shown in FIG. 6 (a), substantially the entire range excluding the peripheral end portion (heat fusion portion 4) of the front and back surface pieces 5. Or may be divided into a plurality of parts as shown in FIGS. 4B and 4C, or may be provided in multiple strips as shown in FIG. May be. Furthermore, the vent 3 is most preferably provided at the upper end 5d, but may be provided at the lower end 5c as shown in FIG. 6 (a), for example, as shown in FIG. You may be provided in the side edge part 5a.

In addition, as described above, the laminated film constituting the bag body 7 does not necessarily include the base layer 52, the barrier layer 53, and the outer surface layer 56. For example, the base layer 52 or When the outer surface layer 56 is a material having a gas barrier property, the barrier layer 53 may not be provided separately. Similarly, if the outer surface layer 56 and the barrier layer 53 are relatively strong materials, for example, the base material layer 52 may not be provided separately. In addition, for example, when filling a filler that does not require a gas barrier property (for example, frozen food), a barrier layer may not be provided, or a layer capable of imparting a different function may be added. Each layer structure of a film can be suitably changed with the raw material and a filler.
The spout 8 is not particularly limited as long as it has the spout and the fused portion 82. For example, the spout 8 does not have the conduit 81, or a rod-like body having a cross-sectional shape in place of the conduit 81 is provided. Various known ones such as those can be used.

  Moreover, in each said embodiment, although the bag main body 7 consists of a film piece of 4 surfaces, for example, the front and back surface pieces 5 and 5 and the side piece 6 and 6 are comprised from the film piece of 1 sheet. Also good. For example, as shown in FIGS. 7 and 8, the front and back surface pieces 5, 5 and the side surface pieces 6, 6 are formed using one film piece 11 on which the nonwoven fabric layer 55 (and the release layer 54) is laminated. Are folded together, and both end portions 11a and 11a of the film piece 11 are overlapped, and the both end portions 11a overlapping portions and the overlapping portions 11b overlapping portions of the front and back surface pieces 5 and the side surface pieces 6 are heat-sealed. By forming 4, the bag body 7 may be configured. According to such a pouch container 1 with a spout, since the cut edge 55a in the longitudinal direction of the nonwoven fabric layer 55 is one place, the cut end portion 55a of the nonwoven fabric layer 55 serving as a filament raising or a water intrusion path is formed as described above. It can be reduced compared to the form. For example, when the pouch container 1 is manufactured or distributed, if the folded end portion (side gusset portion having no cutting edge portion 55a) is placed on a belt conveyor or a packing box, the cutting edge portion of the nonwoven fabric layer 55 is provided. Since 55a does not contact a belt conveyor etc., it can prevent that dust etc. adhere to the filament 9 of the nonwoven fabric layer 55. FIG. In the case of this modification, it is possible to prevent beautiful end treatment and water intrusion without using a heat-fusible filament 9 of the nonwoven fabric layer 55, but more beautiful end treatment and more reliable water intrusion prevention. In order to achieve this, it is preferable to use a heat-fusible filament 9.

  In each of the above-described embodiments, the bag body 7 is a self-supporting type with a double-sided gusset composed of the front and back surface pieces 5 and 5 and the side surface pieces 6 and 6, but the bag body 7 is limited to this. For example, as shown in FIG. 9 (a), a flat type composed of two surfaces in which the peripheral ends of the front and back surface pieces 5 are bonded together, and as shown in FIG. 9 (b), It can be formed in various forms such as a self-supporting type with a single-sided gusset composed of three surfaces of the side piece 6 and a self-supporting type composed of three surfaces of the front and back surface pieces 5 and the bottom film 10 as shown in FIG. it can. Further, in the modification examples of the bag main body 7 such as a self-standing pouch with a single-sided gusset or a flat pouch, the single film piece 11 may be folded in the same manner as in FIG.

  In addition, the filling with which the pouch container 1 with a spout of the present invention is filled is not limited to food such as refrigerated or hot beverages, jelly-like foods, and ice creams, and can be filled with medicines, etc. It can also be used for purposes other than warm storage.
