TECHNICAL FIELD OF THE INVENTION
TECHNICAL FIELD The present invention relates to an integrated packaged product for collectively selling a plurality of products formed of packaging bags in which contents such as food are individually packaged.
[0002]
[Prior art]
Conventionally, instant foods such as instant noodles, sprinkles, instant miso soup and the like have been housed in pillow type or three-sided or four-sided sealed type packaging bags and widely marketed. In addition, these products are packed and packaged by storing a predetermined number in an outer bag or wrapping with a shrink film or the like, and are widely marketed as economical products.
[0003]
The sales form as an economical item has the advantage of increasing the sales volume for the seller, the advantage of the purchase price per unit being lower for the purchaser, and the advantage for both parties. Sales form is increasing.
[0004]
However, such a packaging form has a problem that there is a feeling of excessive packaging and an outer bag or shrink film for stacking and packaging leads to an increase in the amount of dust.
[0005]
Therefore, there has been a demand for an integrated packaging form that does not have the feeling of excessive packaging and can suppress an increase in the amount of waste, and various integrated packaging bodies that meet this demand have been proposed (for example, Patent Document 1, (See 2, 3, 4)
[0006]
However, the stacked packages described in any of the patent documents are also stacked and packaged by a tape such as an adhesive tape, and although there is certainly no feeling of excessive packaging and the amount of dust can be suppressed, In addition, a separate material such as a tape is required, and the appearance is hardly preferable.

With the configuration according to any one of claims 1 and 2, it is possible to obtain an integrated package excellent in display effect without using a separate material.
[0012]
BEST MODE FOR CARRYING OUT THE INVENTION
The present invention will be described in detail below with reference to the drawings and the like.
FIG. 1 is a perspective view showing one embodiment of the stacking package according to the present invention, FIG. 2 is a perspective view of the packing bag before stacking in FIG. 1, and FIG. 3 is one embodiment of the layer structure of the packing bag shown in FIG. FIG. 4 is a perspective view showing another embodiment of the integrated package according to the present invention. In the figure, reference numerals 1 and 1 ′ denote an integrated package, 2 denotes a standing pouch, and 3 denotes a peripheral edge. 3 'is a top heat bonding part, 3' is a peelable heat bonding part, 4 is a 4-pillar type gusset bag, 20 is a laminate, 21 is a first heat bonding resin layer, and 22 is a base material. Layer 23 indicates a second heat-adhesive resin layer.
[0013]
FIG. 1 is a perspective view showing one embodiment of the stacking package according to the present invention, and FIG. 2 is a perspective view of the packing bag before stacking in FIG. 1, wherein the stacking package 1 has contents (not shown). The two pouches 2 of the same size having a gusset folding part (not shown) at the well-known bottom part sealed with a peripheral heat bonding part 3 The top heat bonding portions 3 'and 3', which are one of the top and bottom heat bonding portions 3 'and 3', are separated from each other by the heat bonding portion 3 ". Although the top thermal bonding portions 3 'and 3' are shown in FIG. 1 as having a wide width (label seal shape), they are not shown but formed narrow. It may be.
[0014]
As shown in FIG. 2, a laminate for forming the standing pouch 2 has a base layer 22 having a first heat-adhesive resin layer 21 on one surface, and the other surface of the base layer 22. A laminated body 20 provided with a second thermo-adhesive resin layer 23 at least as an outermost layer, wherein the laminated body 20 is covered with the peripheral thermo-adhesive portion 3 so that the first thermo-adhesive resin layer 21 is exposed. By sealing, the standing pouch 2 can be obtained.
[0015]
As the base layer 22 constituting the laminate 20, a film stretched in a uniaxial or biaxial direction such as polypropylene, polyester, or polyamide is suitable. Further, as the first heat-adhesive resin layer 21 formed on the surface of the base layer 22 which becomes the exposed surface when the bag is formed, a peripheral heat-bonded portion which is removably heat-bonded, for example, the above-described top portion It is only necessary to form at least the exposed surfaces of the heat bonding portions 3 'and 3', and the heat bonding is performed so that the packaging bag (the standing pouch 2 in FIG. 1) of the base layer 22 can be peeled off. The peripheral thermal bonding portion to be formed, for example, is formed partially on the exposed surface of the top thermal bonding portion 3 ′, 3 ′, or the packaging bag of the base material layer 22 (in FIG. The pouch may be formed on the entire surface to be the exposed surface when the standing pouch 2) is formed, and the first heat-adhesive resin layer 21 is formed of the resin constituting the base layer 22. The resin to be formed may be appropriately selected and used. is there.
[0016]
When the first heat-adhesive resin layer 21 is partially formed, a beautiful print layer is usually provided on the surface of the base material layer 22 opposite to the surface on which the first heat-adhesive resin layer 21 is formed. It must be formed in register with the print layer, and is usually formed in-line with the print layer by a gravure printing method. For example, when the base layer 22 is polypropylene, it can be formed using a well-known part coating agent such as chlorinated polypropylene, and when the base layer 22 is polyester or polyamide, It can be formed using a well-known part coat agent such as TEX EC-1700 (Chuo Rika Kogyo Co., Ltd .: trade name). Further, the first heat-adhesive resin layer 21 does not peel off unless the conscious operation of separating the two bags of the pouches 2 and 2 is performed, and when the conscious operation of separating is performed, It is sufficient that the adhesive strength is such that the layer 22 can be separated smoothly without breaking, and the adhesive strength is generally 1 to 10 N / 15 mm width, preferably 3 to 6 N / 15 mm width. By controlling the amount by applying the first heat-adhesive resin or controlling by adjusting the heat and pressure when two bags are integrated and thermally bonded, it is possible to obtain an adhesive strength in the above range. it can. In addition, the peelable thermal bonding portion 3 ″ may be formed by performing thermal bonding using a seal bar partially having a concave portion and a seal bar having a convex portion engaging with the concave portion, if necessary. Alternatively, the base layer 22 may be formed by forming through holes in a plurality of stacked bags at the same time as being thermally bonded. Surface or both surfaces may be subjected to an appropriate adhesion treatment such as corona discharge treatment or anchor agent application.
[0017]
When the first heat-adhesive resin layer 21 is formed on the entire surface of the base material layer 22, the first heat-adhesive resin layer 22 is formed of the same resin as when the first heat-adhesive resin layer 22 is partially formed. However, HS-OP (trade name, manufactured by Tosello Co., Ltd.), FOH [trade name, manufactured by Nimura Chemical Industry Co., Ltd.] : Trade name], or Melinex 850 (manufactured by Mitsui DuPont Polychemicals, Ltd .: trade name).
[0018]
Also, the outermost layer on the opposite side of the surface of the base material layer 22 on which the first heat-adhesive resin layer 21 is formed, actually the innermost layer when a packaging bag (standing pouch 2 in FIG. 1) is used. The second heat-adhesive resin layer 23 to be formed may be formed of a thermoplastic resin that can be securely sealed with heat and pressure when forming a packaging bag (standing pouch 2 in FIG. 1). However, it is preferable to use a resin that has lower-temperature adhesion than the resin that forms the first heat-adhesive resin layer 21 and needs to be appropriately selected depending on the resin that forms the first heat-adhesive resin layer 21 For example, a linear low-density polyethylene, more preferably an ethylene-α-olefin copolymer (linear low-density polyethylene) polymerized by using a single-site catalyst, or a single-layered film thereof. It can be mentioned.
[0019]
In addition, the laminated body 20 may be provided between the base layer 22 and the second heat-adhesive resin layer 23 as required, depending on the required physical properties when formed into a packaging bag (standing pouch 2 in FIG. 1). For the purpose of imparting or improving functions such as mechanical toughness, bending resistance, piercing resistance, impact resistance, cold resistance, heat resistance, chemical resistance and barrier properties, for example, polyester-based, polyamide-based A uniaxially or biaxially stretched film or unstretched film made of a resin such as a polypropylene resin or a water vapor or oxygen gas barrier layer such as aluminum, silicon oxide, aluminum oxide, or polyvinylidene chloride on at least one surface thereof. An intermediate layer (not shown) provided or provided with aluminum foil or saponified ethylene-vinyl acetate copolymer may be used. Can.
[0020]
As a method of laminating the laminate 20, a method of hot-melt extruding polyethylene or the like using a T-die extruder and sandwich laminating each layer, or a method of dry lamination using an urethane-based adhesive or the like A well-known appropriate lamination method can be used.
[0021]
In the case where the standing pouch 2 has a body and a bottom formed of different laminated bodies (so-called two-piece specification), the laminated body used for the bottom is formed of the first heat-adhesive resin layer 21. It is appropriate to adopt a configuration in which is not provided. Although the stacking package 1 of the present invention has been described using a standing pouch, the stacking package 1 of the present invention is not limited to a standing pouch. The present invention can also be applied to a gusset bag, a gusset bag of a four pillar type in which four ridge lines of the gusset bag are thermally bonded, or a shallow drawn blister pack. Although the number of stacked packages of the present invention has been described so far as two bags, the present invention is not particularly limited to this, and it is sufficient to stack as much as possible. In the case of such an accumulation form, 2 to 5 bags are practically appropriate. In addition, the position where the heat is releasably bonded to form the integrated package may be a suitable position (appropriate peripheral heat bonding portion) depending on the form of the packaging bag, as described with reference to FIG. It is not limited to the top heat-sealed portion (the position indicated by reference numeral 3 'in FIG. 1), and is not shown. In a packaging bag having a thermal bonding portion, one peripheral thermal bonding portion of the n-th packaging bag and the other peripheral thermal bonding portion of the (n + 1) -th packaging bag are thermally bonded in a peelable manner. The package may be a solid-state integrated package or a chain-shaped (chain-shaped) integrated package. Further, as shown in FIG. 4 pillar type gusset bag 4 sealed with part 3 The portions 3 'are alternately overlapped in three bags, and the substantially central portions of the peripheral thermal bonding portions 3 which are in contact with each other at the peripheral thermal bonding portion 3 in which the four ridge lines are thermally bonded are peelable by the thermal bonding portion 3 ". 4 shows an embodiment in which three bags are alternately stacked, but this is an example, and the number of bags to be stacked is as follows. It can be determined appropriately.
[0022]
【The invention's effect】
As described in detail above, the integrated package of the present invention is formed without using a separate material such as a tape because the surface of the packaging bag is formed of the first heat-adhesive resin layer having the heat-adhesive property. In addition to simply stacking the packaging bags and applying heat and pressure to predetermined locations, not only can they be easily accumulated, but also they can be accumulated without using foreign materials such as tapes or other materials. It has the effect of being excellent in display effects.
