After that, at a predetermined position on the back surface, as a wireless IC tag 20a, communication is performed by an electromagnetic induction method. A wireless IC tag having dimensions of 45 mm in length × 45 mm in width and 0.6 mm in thickness is used as a heat sealant. It was used and affixed by the thermal bonding method. Next, a coated ball (basis weight 230 g / m ² ) is used as the inner paper layer 12 thereon, the back surface is used as a bonding surface, and low density polyethylene (thickness 30 μm) is used as the adhesive layer 14 therebetween. It was prepared by laminating by the lamination method.
(3) The paper box laminate material 10 was punched out into a carton blank shape, and then the sticking was performed at the bonding portion 8 to produce a sealed carton type paper box 500.
(4) As the spacing member 5, a sheet obtained by punching a double-sided corrugated cardboard sheet having a thickness of 6 mm into a dimension of 72 mm in length and 190 mm in width was used.
(5) The object to be stored 50 containing the metal stored in the paper box 500 was a bag made by heat-sealing a laminated film having the following configuration, packed with PTP-packed tablets, and hermetically packaged.

(Configuration of the laminated film of the bag)
Biaxially stretched polyethylene terephthalate film (thickness 12 μm) / adhesive / biaxially stretched polypropylene film (thickness 25 μm) / adhesive / aluminum foil (thickness 7 μm) / adhesive / linear low density polyethylene film (thickness 80 μm) [sealant layer〕
The above films are laminated by a dry lamination method, and a two-component curable polyurethane adhesive for dry lamination is used as an adhesive between the films.
The to-be-contained object 50 includes an aluminum foil in both the bag and the PTP package.
In the paper box 500, the storage object 50 and the spacing member 5 are inserted so as to be arranged as shown in FIG. 1, and the flap of the opening is closed and sealed with a hot melt adhesive. A paper box with a wireless IC tag of Example 1 was produced.

(Production Example 2)
The paper box with the wireless IC tag of Production Example 2 corresponds to the paper box 600 with the wireless IC tag of Example 2, and changes the dimension of the spacing member 5 to a dimension of 65 mm in length × 65 mm in width, and is punched. All the same as in Production Example 1 except that when the body portion of the adhesive portion 8 of the paper box 600 is pasted, the inner surface of the wall plate where the wireless IC tag 20a is attached is previously pasted with a vinyl acetate emulsion adhesive. Produced.

(Production Example 3)
The paper box with the wireless IC tag of Production Example 3 corresponds to the paper box 700 with the wireless IC tag of Example 3, and a partition plate that partitions the inside of the paper box 700 inside the paper box as shown in FIG. 6, a laminate material in which only the outer paper layer 11 and the inner paper layer 12 are bonded together with the adhesive layer 14 in the configuration of the laminate 10 for the paper box is manufactured, and this is punched to obtain end portions on both sides. The partition plate 6 having the adhesive pieces 7a and 7b is manufactured, and when the paper box 700 is affixed to the body, the wireless IC tag 20a is attached between the top plate and the bottom plate of the paper box 700 with the adhesive pieces 7a and 7b. All were manufactured in the same manner as in Production Example 1 except that a distance of about 12 mm was allowed between the mounted wall plate and the object to be stored 50.

(Comparative Example 1)
The paper boxes with wireless IC tags of Comparative Example 1 were all manufactured in the same manner as in Manufacturing Example 1 except that the insertion of the spacing member 5 was stopped from the paper boxes with wireless IC tags of Manufacturing Example 1.

  In order to evaluate the paper boxes with wireless IC tags of Production Examples 1 to 3 and Comparative Example 1 manufactured as described above, each paper box with wireless IC tags was used as a sample, and a reader / writer (electromagnetic induction method) was used. The readout test of the information stored in the wireless IC tag 20a was performed from the distance.

As a result of the readout test, for each sample of Production Examples 1, 2, and 3, the wireless IC tag 20a mounted between the paper layers of the paper box, and the stored object 50 stored on the back side thereof, Since the distance between them is separated by at least 6 mm or more by the distance holding member 5 or the partition plate 6, it was possible to read out without any particular problem.
On the other hand, in the sample of Comparative Example 1, since the interval holding member 5 is not inserted between the wireless IC tag 20a and the stored object 50, the wireless IC tag 20a and the back side thereof are stored. There is a problem that the distance between the object 50 and the object 50 may approach 1 mm, and the information stored in the wireless IC tag 20a cannot be accurately read due to the adverse effect of the aluminum foil contained in the object 50. It was not preferable.

(Production Example 4)
Although the package with a wireless IC tag of Production Example 4 is not shown in the figure, the container is a bag body that does not contain paper (hereinafter referred to as an outer bag), and a plurality of items to be stored are contained in the outer bag. It is a package of bags.
(Inner bag)
The inner bag uses a laminated film with the following structure and is a continuous bag type in which three 4-sided seal type sachets are connected in the vertical direction and two in the horizontal direction (total of 6) via the perforation line. The granular contents were sealed and produced in each sachet. The outer dimensions of the inner bag are a width of 84 mm and a length of 180 mm.
(Laminated film for inner bag)
The laminated film for the inner bag is a laminate of a biaxially stretched polyethylene terephthalate film (thickness 12 μm) / adhesive / aluminum foil (thickness 7 μm) / adhesive / unstretched linear low density polyethylene film (thickness 40 μm).

(Outer bag)
The outer bag is a gusset-type bag using a laminated film having the following configuration, the width is 84 mm, the length is 180 mm, and the folding widths of the gusset folding portions on both sides are 20 mm each (the thickness when the bag is raised is 40 mm) It produced so that it might become. When making the outer bag, a wireless IC tag was inserted between the layers of the outer bag laminated film.

(Laminated film for outer bag)
The laminated film for outer bags is a laminated body of biaxially stretched polyethylene terephthalate film (thickness 12 μm) (back surface printing) / anchor coat / wireless IC tag / low density polyethylene melt extrusion (thickness 50 μm).
This outer bag laminated film is printed from the back side of the biaxially stretched polyethylene terephthalate film, and at the same time, a register mark is printed at the same time, an anchor coat is applied on the printed surface, and further according to the register mark, A wireless IC tag is attached to a part of the anchor coat surface with an adhesive at a cycle of cutting to the size of a gusset bag (one wireless IC tag is assigned to one gusset bag). did.
This laminated film for outer bag is in a state where the entire surface of the anchor coat is not covered with the wireless IC tag and the anchor coat surface is exposed at an area ratio of 20% or more. The reason for this is that even if low-density polyethylene is melt-extruded on the wireless IC tag, the adhesive strength cannot be obtained. Therefore, the adhesive strength can be maintained by widening the portion that contacts the anchor coat surface where the adhesive strength can be obtained. It is to do. Furthermore, the laminated film for outer bags was subjected to extrusion coating (melt extrusion coating) with a thickness of 50 μm of the sealant layer low density polyethylene from above.

  The package with a wireless IC tag of Production Example 4 uses this laminated film for outer bags to stack eight inner bags in a continuous bag form in which granular contents are hermetically sealed inside the outer bag in a gusset form. Furthermore, a foamed polypropylene plate having a width and length of the inner bag of approximately the same dimensions and a thickness of 5 mm is stacked thereon as a spacing member, and the foamed polypropylene plate is enclosed in a laminated film. After being inserted so as to be positioned on the wireless IC tag side, the opening of the outer bag was heat sealed.

(Comparative Example 2)
The package with the wireless IC tag of Comparative Example 2 was produced in the same manner as in Production Example 4 except that the insertion of the spacing member was stopped from the package with the wireless IC tag of Production Example 4.

  In order to evaluate the package with the wireless IC tag of Production Example 4 and Comparative Example 2 produced as described above, each package with the wireless IC tag was used as a sample, and a reader / writer (electromagnetic induction method) was used. The readout test of the information memorize | stored in the wireless IC tag from the distance of was conducted.

As a result of the readout test, for the sample of Production Example 4, the interval between the wireless IC tag mounted on the outer bag and the object stored on the back side thereof is at least 5 mm or more by the interval holding member. Since they were separated, they could be read without any problems.
On the other hand, in the sample of Comparative Example 2, since the interval holding member is not inserted between the wireless IC tag and the object to be stored, the wireless IC tag and the object to be stored on the back side thereof In some cases, the distance of 1 mm approaches 1 mm, which is adversely affected by the aluminum foil contained in the object to be stored, and the information stored in the wireless IC tag cannot be read accurately.
