Description

  The present invention relates to a packaging bag and a pouch container with a spout.

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 laminated film is known. A pouch container with a spout filled with ice confectionery such as ice cream is also known. When such a container is taken out from a refrigerator or a freezer, there is a problem that condensation occurs rapidly and wets the handle and the mounting surface. This problem is particularly noticeable in hot and humid places.
In this regard, Japanese Patent Application Laid-Open No. 2001-130586 discloses a pouch container with a spout made of a film in which a foamed resin sheet is laminated. According to such a pouch container, since the heat insulating property is imparted by the foamed resin sheet, it has an excellent effect of preventing dew condensation on the bag surface.
However, even if the foamed resin sheets are laminated in this way, it is difficult to prevent water droplets from adhering to the bag surface.

JP2001-130586

  An object of the present invention is to provide a packaging bag and a pouch container with a spout that are improved so that the surface of the bag is not easily wetted by condensed moisture after being taken out in a cooled state.

In view of the fact that it is difficult to completely prevent water droplets from adhering to the bag surface using a heat insulating material, the present inventors guide the moisture adhering to the surface to the inside of the bag and remove it from the surface. The present invention has been completed.
That is, the present invention is formed by forming a flexible laminated film having a surface film layer into a bag shape, and a water absorbing layer having water absorption is provided on the inner surface of the surface film layer. A plurality of holes for water communication leading to the water absorption layer are formed, an inclined surface is formed around the hole portion on the outer surface of the surface film layer, and the outer surface of the surface film layer and the hole portion Provided is a packaging bag having an opening peripheral surface subjected to a hydrophilic treatment .

The packaging bag is filled with a frozen dessert such as a beverage or ice cream, and after cooling and taking out, moisture adheres to the outer surface of the surface film layer, but includes the outer surface of the surface film layer and the inclined surface of the hole. Since the peripheral surface portion of the opening is hydrophilized, moisture adhering to the outer surface of the surface film layer spreads in a film shape to reach the hole portion and is quickly absorbed into the water absorption layer. Thus, the water | moisture content adhering to the surface film layer of a bag can be removed by absorbing the water | moisture content condensed by the water absorption layer.
Moreover, in the preferable aspect of the said packaging bag, a part of water absorption layer protrudes in the hole. In such a packaging bag, there is no possibility that moisture flowing along the outer surface of the surface film layer will pass through the hole, and can be more reliably guided to the water absorbing layer.

Further, the second means of the present invention is a bag body which has at least a front and back surface portion made of a flexible laminated film having a surface film layer and is formed into a bag shape by heat-sealing the peripheral edge portion. And a spout attached to the bag body, a water-absorbing layer having water absorption is provided on the inner surface of the surface film layer, and a plurality of holes for water passage leading to the water- absorbing layer are formed in the surface film layer. A pouch container with a spout , in which an inclined surface is formed around the hole portion on the outer surface of the surface film layer, and the outer surface of the surface film layer and the opening peripheral surface portion of the hole portion are subjected to hydrophilic treatment. provide.

The said pouch container with a spout is used, filling frozen confectionery, such as a drink and ice cream, for example. And after cooling this and taking out, moisture adheres to the outer surface of the surface film layer, but the outer peripheral surface portion including the outer surface of the surface film layer and the inclined surface of the hole is hydrophilized. Moisture adhering to the outer surface spreads in a film shape, reaches the hole, and is quickly absorbed into the water absorption layer .
In a preferred embodiment of the spout-equipped pouch container, a part of the water absorption layer protrudes into the hole. In such a pouch container with a spout, moisture flowing along the outer surface of the surface film layer does not have to pass through the hole, and can be more reliably guided to the water absorption layer.

The packaging bag and the pouch container with a spout of the present invention can absorb moisture adhering to the outer surface of the surface film layer with the water absorption layer. Accordingly, even if the battery is taken out outside in the cold state, water droplets do not accumulate on the bag surface, and the handle and the mounting surface can be made difficult to get wet. Further, since the outer surface of the surface film layer and the opening peripheral surface portion of the hole are hydrophilized, moisture attached to the outer surface of the film layer can be captured by the hole and permeated into the water absorption layer . Therefore, the moisture adhering to the outer surface of the film layer can be more reliably and quickly removed.

Hereinafter, embodiments of the present invention will be specifically described with reference to the drawings.
1 to 4, reference numeral 1 denotes a pouch container with a spout in which a spout 8 is attached to a bag body 5 composed of front and back surface portions 2 and 2 and both side surface portions 3 and 3 constituting a side gusset. Such a pouch container 1 with a spout is a self-supporting pouch in which, after filling, the bottom portions 1a for mounting are formed by folding back the lower portions of the front and back surface portions 2 and 2.

The bag body 5 is composed of four flexible film pieces, that is, a front surface portion 2, a back surface portion 2, and both side surface portions 3, 3, and is formed into a bag shape by thermally fusing the inner surfaces of the peripheral portions of the surface portions 2, 3 together. Is formed.
The flexible film constituting the front and back surface portions 2 and 2 and the side surface portions 3 and 3 is a laminated film in which a water absorbing layer 52 is laminated on the inner surface of a water-permeable surface film layer 51. Specifically, as shown in FIG. 3, the laminated film includes, for example, a surface film layer 51 for imparting surface friction, heat resistance, and the like in order from the outside to the inside, and water absorption capable of absorbing moisture. A base film layer 53 having a layer 52, a barrier layer for maintaining the strength of the bag (flexibility, pinhole resistance, etc.) and imparting gas barrier properties (and light-shielding properties); A sealant layer 54 is formed by laminating the three together to form a bag shape.
In FIG. 3, an adhesive layer for adhering the layers 51, 52, 53, and 54 is not shown. The same applies to other sectional views showing the laminated film.

  As the surface film layer 51, for example, a polyester film such as polyethylene terephthalate, a polyamide film such as polypropylene or nylon, or a laminate of two or more kinds can be used. Further, in the case of a synthetic resin film, a stretched film is used. It is preferable to use it. 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 surface film layer 51 is, for example, about 10 to 70 μm. In addition, although not shown in particular, the design printing on which the display of a brand name, a pattern, etc. is printed on the inner surface or the outer surface of the surface film layer 51, and when applying this design printing to the inner surface, the surface film The layer 51 is transparent.

The surface film layer 51 itself is made of a water-resistant film that does not allow water to pass through. However, by forming a plurality of holes 6 that penetrate the film layer 51, moisture can pass between the layers. ing. Specifically, as shown in FIG. 4B, a plurality of hole portions 6 penetrating from the outer surface to the inner surface of the film are formed in the entire surface film layer 51. The plurality of holes 6 may be formed regularly, or may be formed irregularly without any particular restriction.
The hole 6 is formed in a substantially circular shape as shown in the figure, but may have other shapes. The size of one hole 6 is not particularly limited. However, when design printing is performed on the surface film layer 51, considering that the design is not impaired, the substantially circular hole 6 is provided. In this case, the diameter is preferably about 0.05 to 0.5 mm. Moreover, the formation interval of each hole 6 is formed to be about 1 to 7 mm, for example.
The hole 6 may be formed so as to penetrate not only the surface film layer 51 but also the water absorption layer 52.

  Furthermore, the surface film layer 51 is subjected to a hydrophilic treatment. Specifically, as shown in FIG. 4B, the outer surface 51a of the surface film layer 51 and the opening peripheral surface portion 6a of the hole 6 are subjected to a hydrophilic treatment (in FIG. 4B). The portion that has been hydrophilized is represented by a fine thin diagonal line). It does not specifically limit as a hydrophilization process, Well-known means, such as a corona discharge process, an ultraviolet-ray process, a plasma process, a coating agent process, can be used. By being made hydrophilic in this way, the water adhering to the outer surface 51a of the surface film layer 51 does not form large water droplets, but spreads in the form of a film on the outer surface 51a of the surface film layer 51 to the peripheral surface portion 6a of the hole 6. The water that has been reliably guided and reaches the hole 6 is quickly absorbed into the water absorption layer 52 by capillary action or the like. Such hydrophilization results in the wetting tension (wetting index) of the outer surface 51a of the surface film layer 51 and the opening peripheral surface portion 6a of the hole 6 being 40 mN / m or more (value according to the wetting test method of JIS K-6768). It is preferable to do so.

The water absorption layer 52 is laminated so as to substantially contact the entire inner surface of the surface film layer 51. As the water absorption layer 52, a layer having a water absorption amount of about 50 to 200 ml / m ² is preferably used. The material of the water-absorbing layer 52 is not particularly limited, and water-absorbing paper, a non-woven fabric that can absorb water, a porous water-absorbing foam sheet, and the like can be used. Alternatively, the water absorbing layer 52 may be configured by applying a water absorbing polymer such as a cross-linked polyacrylate or starch-polyacrylate to the inner surface of the surface film layer 51. Among these, it is preferable to use water-absorbing paper such as rayon paper because of its excellent water absorption.
Moreover, since not only water absorption but heat insulation can be provided, it is preferable to use a water absorbing foam sheet and a nonwoven fabric as the water absorption layer 52, and it is more preferable to use a nonwoven fabric especially. Examples of the nonwoven fabric include nonwoven fabrics made of water-absorbing fibers such as rayon, cotton and pulp, mixed fibers in which water-absorbing fibers and water-absorbing fibers such as polypropylene are mixed, or water-absorbing nonwoven fabrics made of composite fiber composites, and non-water-absorbing fibers. Water-absorbing nonwoven fabric made of fibers with hydrophilic treatment applied to water-soluble fibers, and water-absorbing polymers coated with non-water-absorbing fibers such as water-absorbing fibers or acrylic fibers, for example, in combination with water-absorbing polymers to increase water absorption A water-absorbing nonwoven fabric made of the prepared fibers can be used. A nonwoven fabric produced by a known molding method such as a needle punch method, a spun bond method, an adhesion method, or a melt blow method can be used. Further, in order to absorb moisture quickly and in large quantities, it is preferable to use a material having a denier of about 1.0 to 3.0 d and a basis weight of about 10 to 30 g / m ² . The thickness is preferably about 100 to 200 μm.

The base film layer 53 is not particularly limited as long as it is relatively excellent in strength. Polyamide film such as nylon, polyester film such as polyethylene terephthalate, polypropylene film such as polypropylene and propylene-ethylene copolymer, etc. A synthetic resin film, synthetic paper, or two or more types of laminates 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. Furthermore, the base film layer 53 is provided with gas barrier properties by laminating an aluminum foil on the film or depositing or coating a gas barrier material such as aluminum. The thickness of the base film layer 53 is, for example, about 10 to 70 μm. In addition, when the bag strength can be maintained by the surface film layer 51, the base film layer 51 can be omitted. Moreover, since a gas barrier property may be unnecessary depending on the filler, in this case, the laminated film may not have a barrier layer.
The sealant layer 54 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, and ethylene-vinyl acetate copolymer 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 54 is, for example, about 30 to 150 μm.

  The spout 8 includes a spout attached with a detachable cap and a portion to be fused as an attachment portion to the bag body 5, and the material thereof may be formed of various synthetic resins, metals such as aluminum, and the like. However, since it can be easily attached to the upper edge portion of the bag body 5, it is preferable that at least the peripheral surface of the fusion-bonded portion can be heat-sealed with the inner surfaces of the front and back surfaces. The spout 8 can be formed of, for example, a synthetic resin molded product such as polyethylene or polypropylene, and can be satisfactorily heat-sealed. Therefore, the spout 8 is preferably made of the same material as the sealant layer of the front and back surfaces 2.

The spouted pouch container 1 can be manufactured by the following procedure.
A sheet-like water-absorbing layer 52 is laminated on the inner surface side of the surface film layer 51 whose design is printed on the inner surface to produce a first laminate. As a laminating method of the water absorption layer 52, it can laminate | stack by well-known methods, such as extrusion lamination using polyethylene etc., dry lamination, wet lamination. Especially, it is preferable to carry out by extrusion lamination from the point that the resin component does not easily permeate into the water absorption layer 52 and the water absorption hardly decreases.
Next, a plurality of through holes (holes 6) are formed in the obtained first laminate using a punching device having a needle-like or punching-type punching head. The perforation direction is not particularly limited, but a needle heated to a temperature at which the surface film layer 51 can melt (about 200 to 300 ° C.) in order to prevent the peripheral edge of the through-hole from rising from the outer surface 51 a of the surface film layer 51. It is preferable to perforate from the inner surface side of the water absorption layer 52 using a perforated head having a shape. When the heated piercing head is moved away from the inner surface side of the water absorbing layer 52, the film is melted when the piercing head 10 is passed through the surface film layer 51 as shown in FIG. As shown in (b), when the perforation head 10 is retracted, the molten resin follows this and is drawn inward. In this case, a slightly recessed inclined surface 6b is formed around the hole 6 in the outer surface 51a of the surface film layer 51, and moisture can be easily guided into the hole 6 through the inclined surface 6b. As another means for preventing the peripheral edge of the through-hole from rising from the outer surface 51 a of the film layer 51, the hole 6 may be punched from the outer surface side of the surface film layer 51 using an unheated punching head.

Next, a corona discharge treatment or the like is performed on the surface film layer 51 to hydrophilize the opening peripheral surface portion 6 a of the hole 6 and the entire outer surface 51 a of the surface film layer 51.
And by laminating and laminating the water-absorbing layer 52 of the first laminate on the base film layer 53 of the second laminate consisting of the sealant layer 54 and the base film layer 53 that have been prepared separately, The laminated film of the present invention is obtained. In addition, it is preferable to perform lamination | stacking of the base film layer 53 and the water absorption layer 52 by extrusion lamination similarly to the above.
After that, according to a known manufacturing method, the sealant layer 54 of the obtained laminated film is overlaid, and the peripheral portion is heat-sealed so as to form the front and back surface portions 2, 2 and the side surface portions 3, 3 of the bag body 5, The pouch container 1 with the spout can be manufactured by obtaining a bag body 5 having an upper edge opening type and heat-sealing the upper edge portion with the portion to be fused of the spout 8 sandwiched therebetween. it can.

In the pouch container 1 with a spout, since the water absorption layer 52 is interposed on the inner surface of the surface film layer 51 in which the hole 6 is formed, for example, after cooling it and taking it out, the surface film layer 51 over time. Even if moisture begins to adhere to the outer surface 51 a, the moisture penetrates into the water absorption layer 52 through the hole 6 and is removed from the outer surface 51 a of the surface film layer 51. In particular, since the outer surface 51a of the surface film layer 51 and the opening peripheral surface portion 6a of the hole 6 are hydrophilized, the adhering moisture does not form large water droplets, but spreads in the film shape on the surface film layer 51 and enters the hole 6. Thus, the water absorption layer 52 is quickly absorbed by a capillary phenomenon or the like. Therefore, even if the pouch container 1 with a spout filled with frozen confectionery is left in a hot and humid place for a relatively long time, for example, a large amount of water does not adhere to the surface and water does not easily adhere to the handle. Wetting of the mounting surface can also be prevented.
Furthermore, since the plurality of holes 6 are formed in the surface film layer 51, a slight unevenness is generated, and the pouch container 1 with a spout which is not slippery is obtained.
Moreover, when a nonwoven fabric or a foam sheet is used as the water absorption layer 52, the temperature of the filling is difficult to be transmitted to the surface film layer 51, and therefore, the dew condensation prevention effect is excellent. Therefore, it is possible to prevent moisture from adhering to the surface in synergy with the water absorption by the water absorption layer 52.

As described above, various embodiments of the present invention have been described. However, the present invention is not limited to the above-described various configurations, and can be appropriately changed in design. Hereinafter, parts different from those of the above embodiments will be mainly described, the description of the same components will be omitted, and names and figure numbers will be used.
The bag body 5 in each of the above embodiments is composed of a laminated film in which a water absorption layer 52 and a base film layer 53 (a sealant layer 54 when the base film layer 53 is not laminated) are adhered to the entire surface. However, for example, as shown in FIG. 6A, a laminated film in which a gap portion 7 is provided between the water absorption layer 52 and the base film layer 53 except for the peripheral portion may be used. The bag body 5 provided with such voids 7 is preferable because the water absorption layer 52 can easily swell and can absorb and retain a larger amount of moisture. In addition, the bag body 5 can be configured more flexibly due to the presence of the gap 7. Therefore, it is particularly suitable for the pouch container 1 with a spout that pours out the filling while squeezing the bag body 5.

  The means for forming the void 7 is not particularly limited. For example, as shown in FIG. 6B, a sub sealant layer 55 is laminated on the outer surface of the base film layer 53, and the sub sealant layer 55 is heated. The gap portion 7 can be formed by laminating the water-absorbing layer 52 of a material that can be fused and thermally fusing only the peripheral portion of the water-absorbing layer 52 to the sub sealant layer 55. In this case, as the secondary sealant layer 55, for example, a polyethylene or polypropylene resin may be laminated. The water absorbing layer 52 is a fiber that can be heat-sealed to the secondary sealant layer 55 and has at least the surface thereof a fiber having a heat-sealable resin such as polyethylene such as high-density polyethylene and linear low-density polyethylene, and polypropylene. A non-woven fabric can be used. Examples of such fibers include solid fibers or hollow fibers made of a heat-fusible resin such as polyethylene, and a heat-fusible resin 92 around a core material 91 as shown in FIG. The coated fibers 9 and the like are exemplified, and among these, the core is relatively excellent in strength, such as polyamide fibers such as nylon, polyester fibers such as polyethylene terephthalate, etc. because of being strong against pressure and ensuring air retention of the nonwoven fabric. A heat-fusible conjugate fiber in which a material 91 is coated with a heat-fusible resin 92 such as linear low-density polyethylene is preferable. Examples of such a heat-fusible filament 9 include trade name Elves (manufactured by Unitika Ltd.).

Further, as another means, as shown in FIG. 6C, a release agent 56 such as silicone or polyamide nitrified cotton-based resin coating agent is formed in the region where the void 7 is to be formed in the outer surface of the base film layer 53. By applying the gravure printing method or the like and laminating the base film layer 53 and the water absorption layer 52 by a dry lamination method or the like, the release agent coating portion becomes non-adhering and the void portion 7 can be formed. .
As another means, the void portion 7 can be formed by applying an adhesive to a desired portion of the outer surface of the base film layer 53 and laminating the water absorbing layer 52 thereon.
The gap 7 may be divided into a plurality of parts as shown in FIG. 7B, for example, in addition to being provided in substantially the entire range excluding the peripheral part. It may be provided only for.

  Further, in each of the embodiments described above, the sheet-like water absorption layer 52 and the surface film layer 51 are bonded to each other, but may be partially bonded, for example. Thus, by partially adhering between both layers 51 and 52, it is possible to prevent the opening of the hole 6 formed in the surface film layer 51 from being blocked by the adhesive layer. In particular, this is effective when the surface film layer 51 in which the hole 6 is formed in advance is laminated and bonded to the water absorption layer 52.

Moreover, in each said embodiment, although the hole 6 is formed in the whole bag main body 5, the hole 6 may be formed in a part of bag main body 5. FIG. For example, as shown to Fig.8 (a), as shown in the same figure (b) as what the hole 6 is formed in the part except the peripheral part (thermal fusion part) of the bag main body 5, Although the hole 6 is not formed in the side surface part 3 and the hole 6 is formed only in the front and back surface part 2, or not particularly illustrated, the lower part of the front and back surface parts 2 and 2 (of the pouch container 1 with a spout) The thing etc. in which the hole part 6 is formed in the range except the bottom face 1a) are illustrated. The water absorption layer 52 can be partially provided so as to correspond to the formation region of the hole 6. Therefore, for example, the side surface portions 3 may be formed of a laminated film that does not have the hole 6 and the water absorption layer 52.
Further, the hydrophilic treatment, that provided on both the outer surface 51a of the opening peripheral surface 6a and a surface film layer 51 of the hole 6.

  Further, as shown in FIG. 9, for example, a part of the water absorption layer 52 may protrude from the hole 6. Thus, when the water absorption layer 52 protrudes so that it may peek inside the opening peripheral surface part 6a of the hole 6, the moisture which flows along the outer surface 51a of the surface film layer 51 may pass through the hole 6. Therefore, the water absorption layer 52 can be guided more reliably. Examples of the means for causing the water absorbing layer 52 to protrude into the hole 6 include a method in which the hole 6 is formed and then pressurized from the inner surface side of the water absorbing layer 52 to the surface film layer 51 side. In particular, the water-absorbing layer 52 made of a material in which fiber elements are entangled with each other, such as a nonwoven fabric, has an advantage that the fibers easily come out inside the hole 6.

  Moreover, if the foam sheet which has a bubble which continues from the outer surface to the inner surface is used as the surface film layer 51, for example, the perforating process of the hole 6 can be omitted, and moisture can be absorbed by the water absorption layer 52 through the continuous bubble. be able to. As the surface film layer 51, various types can be used as long as moisture can move through the layers.

Moreover, in each said embodiment, although the bag main body 5 is a self-supporting type with a double-sided gusset which consists of four surfaces of the front and back surface parts 2 and 2 and both side surface parts 3 and 3, the bag main body 5 is not restricted to this form, For example, a flat type composed of two surfaces in which the peripheral end portions of the front and back surface portions 2 are bonded to each other, a self-supporting type with one side gusset composed of three surfaces of the front and back surface portions 2, 2 and the side surface portion 3, It can be formed in various forms such as a self-supporting type consisting of three surfaces. In addition, the front and back surface portions 2 and the side surface portions 3 are formed of separate and independent film pieces, for example, a so-called one-side seam type in which one film is appropriately folded to form the front and back surface portions 2 and the side surface portions 3. The bag body 5 may be used, or the bag body 5 in which the front and back surface portions 2 and the side surface portions 3 are formed by appropriately folding two film pieces.
Furthermore, in each said embodiment, although the pouch container 1 with a spout which attached the spout 8 to the bag main body 5 is illustrated, this invention can also be used as a packaging bag (bag main body) to which the spout 8 is not attached. Is possible.
In addition, although the packaging bag and the pouch container 1 with a spout of the present invention are effective to be filled with a frozen confectionery such as a drink to be cooled, a jelly-like food, or an ice cream, it should be used for applications other than the frozen confectionery filling. Is also possible.
