Abstract

<P>PROBLEM TO BE SOLVED: To provide an IC tag-fitted pouch in which the heat resistance of an IC tag does not raise any problem, and the size of a bag is not increased. <P>SOLUTION: The pouch constitutes a storage space between opposing two sheet walls 20 and 30. The pouch is constituted by storing an IC tag 55 in a storage part constituted between a wall surface of one sheet wall 20 and a third sheet material 51 opposite to the wall surface. Since the IC tag 55 is not held in a heat seal area around the pouch, the heat resistance of the IC tag 55 does not raise any problem. Further, the projected area when viewed from the front side of the bag is the same as that without any IC tag 55, and the size of the bag is not increased either. <P>COPYRIGHT: (C)2010,JPO&INPIT

Description

  The present invention relates to a pouch incorporating an IC tag.

  In recent years, it has been proposed to embed IC tags in daily necessities, foods, and other products. The IC tag stores information useful for the consumer such as producer information and distribution history, and the consumer can confirm this with an appropriate reader (reader) (traceability).

As a method of incorporating an IC tag into a pouch or package made of a flexible film material or sheet material, the IC tag is attached to the front surface or back surface (pouch contents side) of the pouch with an adhesive tape or the like. Although it is conceivable to fix it, in such a case, there is a problem that the IC tag is dropped during transportation or at the storefront, or the IC tag is mixed into the contents in the pouch.
As a package for solving such a problem, those disclosed in Patent Document 1, Patent Document 2, and the like are known, but in that case, the position of the IC tag in the pouch becomes a problem. .

  In Patent Document 1, an IC tag is incorporated in a seal area on the outer periphery of the pouch. For this reason, the heat resistance of the IC tag becomes a problem, and it may be adversely affected by heat.

Patent Document 2 discloses a bag incorporating a detection tag for shoplifting prevention. In this bag, a separate dedicated area for storing the detection tag is provided on the upper portion of the bag body for storing the product (CD). And the said exclusive area is divided from the bag main body by the division seal.
Such a configuration is not preferable because it adds an area that is not necessary in consideration of the bag's original purpose of storing merchandise, which leads to an increase in the size of the bag.

JP 2006-69560 A Japanese Utility Model Publication No. 7-31636

  In view of the above circumstances, the object of the present invention is that the IC tag does not fall out of the pouch or mix into the contents, the heat resistance of the IC tag does not become a problem, and the size of the bag is large. An object of the present invention is to provide a pouch with an IC tag that does not lead to an increase in size.

  According to the present invention, a pouch with an IC tag having the following features is provided. The pouch with an IC tag of the present invention forms an accommodation space between two opposing sheet walls. And the IC tag is accommodated in the accommodating part comprised between the wall surface of one sheet wall, and the 3rd sheet | seat material which opposes the said wall surface.

In the pouch with an IC tag of the present invention having the above-described configuration, the third sheet material is disposed so as to face the wall surface of the sheet wall of the pouch, and an accommodating portion is formed between the sheet wall and the third sheet material. is doing. Therefore, the projected area when viewed from the front of the bag is the same as when the IC tag is not provided, and therefore the bag is not enlarged.
In addition, an IC tag accommodating portion is present on the wall surface of the seat wall. That is, in the seal area around the pouch, a configuration in which the IC tag is sandwiched between the heat sealed areas is not employed. Therefore, the heat resistance of the IC tag is not a problem in relation to the peripheral heat seal at the time of manufacturing the pouch.

  The third sheet material may be located outside the pouch, but is preferably located between the two sheet walls. This is because when the third sheet material is present inside, the printing applied to the outer surface of the sheet wall becomes better, and the appearance of the pouch can be configured smartly.

  Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. FIG. 1 is a front view of an IC tag pouch 10 according to an embodiment of the present invention, and FIG. 2 is a cross-sectional view taken along the line 2-2 in FIG.

≪Pouch overall structure≫
The IC tag-attached pouch 10 constitutes a storage space 40 between two opposing sheet walls 20 and 30, and contents such as food are stored in the storage space 40. The pouch 10 has a rectangular shape, and the sheet walls 20 and 30 are sealed and bonded in the seal areas 11, 12 and 13 on three sides.
An opening / closing chuck 15 is provided at a position slightly inward of the upper side of the pouch 10 and can be repeatedly opened and closed. The opening / closing chuck 15 itself is generally known.

On the inner wall surface of one sheet wall 20, a housing portion 50 that houses the IC tag 55 is formed. That is, the third sheet material 51 is disposed between the sheet walls 20 and 30. The upper side 51a and the lower side 51b of the sheet material 51 are sealed to the sheet wall 20, and the side sides 51c and 51d are sealed so as to be sandwiched between the sheet walls 20 and 30 (see FIG. 1).
As described above, the third sheet material 51 is sealed on its four sides, and the IC tag 55 is accommodated in the accommodating portion 50 formed inside.

As shown in FIG. 2, the IC tag 55 is preferably fixed on the inner surface of the sheet wall 20 using an adhesive 55a or the like. Alternatively, the IC tag 55 may be fixed on the inner surface of the third sheet material 51. The fixing method is not limited to the adhesive material 55a, and any appropriate means can be employed.
For example, PE (polyethylene) that functions as a heat seal layer is applied to the entire surface of one side of the IC tag 55. Then, when heat-sealing, heat-sealing is performed by applying heat only to other areas, avoiding areas that are susceptible to heat, such as circuits and antennas in the IC tag 55.

≪No increase in bag size≫
In the present invention, the third sheet material 51 is disposed so as to face the wall surface of the sheet wall 20 of the pouch, and the accommodating portion 50 is formed between the sheet wall and the third sheet material. Therefore, it can be seen that the projected area when viewed from the front of the bag (FIG. 1) is the same as when the IC tag is not provided, and the bag is not enlarged.

≪Heat resistance of IC tag is not a problem≫
Moreover, the accommodating part 50 is comprised on the wall surface of a sheet | seat wall. In other words, a configuration is not adopted in which “the IC tag is sandwiched in the heat-sealed seal region in the seal region around the pouch”. Therefore, the heat resistance of the IC tag 55 is not a problem in relation to the peripheral heat seal at the time of manufacturing the pouch.

≪Method of manufacturing pouch≫
In the present invention, the method for producing the pouch is not particularly limited, but an example will be briefly described as follows.
(1) With the sheet walls 20 and 30 facing each other, each is pulled out from the roll. At this time, the third sheet material 51 is pulled out between the sheet walls 20 and 30. At this time, each sheet is pulled out in the flow direction indicated by an arrow in FIG.
(2) The IC tag 55 is disposed between the sheet wall 20 and the sheet material 51 on the upstream side of the flow. At this time, it is preferable to fix the IC tag 55 to an appropriate position on the sheet wall 20 or the sheet material 51 by using an adhesive material 55 a such as a double-sided tape.
(3) On the downstream side of the position where the IC tag 55 is disposed, the upper side 51a and the lower side 51b of the sheet material 51 and the side sides 51c and 51d of the pouch are heat-sealed. Then cut and cut into each pouch. In this state, the bottom 12 of the pouch is not sealed and is an opening. The contents are filled from this opening, and finally the bottom 12 is heat-sealed.
In the illustrated example, the periphery of the pouch above the opening / closing chuck 15 is not sealed, but other configurations may be employed. That is, as will be described later in the second embodiment of FIG. 3, the pouch periphery 18 above the opening / closing chuck 15 is also heat-sealed, and the consumer places the heat sealing portion at a position above the opening / closing chuck 15. It is good also as a structure to tear off. The pouch can be opened and closed by the opening / closing chuck 15 even after it has been torn once.

≪Modification≫
In the embodiment shown in FIGS. 1 and 2, the third sheet material 51 is located between the two sheet walls 20 and 30. In other words, the IC tag accommodating portion 50 exists inside the pouch. However, in the present invention, the third sheet material 51 may be provided on the outer surface side of the sheet wall, and the IC tag accommodating portion 50 may be positioned outside the pouch.

In the illustrated example, two independent sheet walls 20 and 30 are opposed to each other, three sides are heat-sealed, and the other one side can be opened and closed. However, the configuration may be such that once all four sides are heat-sealed and once opened, it cannot be resealed. Note that the overall shape of the pouch need not be rectangular.
Further, instead of using two independent sheet walls 20 and 30, one sheet wall may be folded to constitute an opposing wall portion, and appropriate side edges may be heat sealed.

≪Constituent material of each sheet≫
The material and the laminated structure constituting the sheet walls 20 and 30 are not particularly limited in the present invention, and are appropriately selected according to the type of contents. When the sheet walls 20 and 30 are fixed by heat sealing, the sheet walls 20 and 30 may have at least a base material layer and a thermoplastic resin layer (seal layer).

  As the base material layer, a simple substance such as a biaxially stretched nylon film, a biaxially stretched polypropylene (OPP) film, a biaxially stretched polyester resin film or a laminate thereof is used, and a biaxially stretched polyester resin film is particularly suitable. Used for.

  The thermoplastic resin layer may be any layer that can be melted by heat and fused together to form a bag. For example, low density polyethylene, medium density polyethylene, high density polyethylene, linear ( Cotton) Low density polyethylene, ethylene / α-olefin copolymer, polypropylene, ethylene / vinyl acetate copolymer, ionomer resin, ethylene-ethyl acrylate copolymer polymerized using metallocene catalyst (single site catalyst) Polyolefin resins such as ethylene-acrylic acid copolymer, ethylene-methacrylic acid copolymer, ethylene-propylene copolymer, methylpentene polymer, polyethylene or polypropylene, acrylic acid, methacrylic acid, maleic anhydride, fumaric acid, etc. Acid-modified polyolefin resin modified with unsaturated carboxylic acid It one not selected et can be used two or more kinds. The thickness of the thermoplastic resin layer is preferably about 10 μm to 100 μm in consideration of heat sealability and the like.

  Further, when the contents are liquid, or when the contents are easily changed by moisture or oxygen, the bag body is required to have high water vapor barrier properties and gas barrier properties. In such a case, a barrier layer can also be formed between the base material layer and the thermoplastic resin layer. As the barrier layer, basically, any vapor-deposited film in which a metal or a metal oxide is vapor-deposited can be used. Examples of the material thereof include silicon (Si), aluminum (Al), magnesium (Mg), Metals such as calcium (Ca), potassium (K), tin (Sn), sodium (Na), boron (B), titanium (Ti), lead (Pb), zirconium (Zr), yttrium (Y) or their oxidation Things can be used.

In addition, since it is assumed that the pouch is subjected to severe physical and chemical conditions during transportation, post-production transportation, and storage, the pouch has high sealing performance, pinhole resistance, heat resistance, light resistance, Quality maintenance, workability, hygiene, etc. may be required. Therefore, in order to satisfy these various conditions, an intermediate layer can be laminated between the base material layer and the thermoplastic resin layer.
As the intermediate layer, for example, a polyester resin, a polyamide resin, a polycarbonate resin, a polyvinyl alcohol resin, a saponified ethylene-vinyl acetate copolymer, or the like can be used.

About the 3rd sheet material 51, a sealing layer is provided in both sides of sheet material 51, and a baffle plate is inserted between sheet walls 30 in a heat sealing process, and it is prevented from adhering to sheet wall 30.
In addition, the structure which provides a sealing layer only in the single side | surface of the 3rd sheet | seat material 51 may be sufficient. In that case, the width of the third sheet material 51 (width in the lateral direction in FIG. 1) is slightly shorter than the width of the sheet walls 20, 30, and both ends of the third sheet material 51 are sealed regions 11, Heat seal so that it is located inside 13. Then, the third sheet material 51 is heat-sealed and fixed to either the sheet wall 20 or 30. In the sealing areas 11, 13, the sealing walls 20 and 30 are directly heat sealed.

<< Second Embodiment: FIG. 3 >>
Next, a second embodiment of the present invention will be described with reference to FIG. In the second embodiment, the specific configuration of the third sheet material 51 is different from that of the first embodiment.
That is, in the first embodiment, as shown in FIG. 2, the upper side 51a and the lower side 51b of the third sheet material 51 are sealed on the wall surface (not the peripheral part) of the sheet wall 20, and as a result. In particular, when the sheet wall 20 is transparent, the seal line can be visually recognized from the outside, so that restrictions are added to the package design (designability is low).

In order to eliminate such inconvenience, in the second embodiment, a large sheet is used as the third sheet material 51, the upper side 51a is disposed along the opening / closing chuck 15, and the lower side 51b is sealed at the bottom of the pouch. Arranged along the region 12.
In other words, in the second embodiment, the upper side 51a of the third sheet material is pulled up to the position of the opening / closing chuck 15 and the lower side 51b of the third sheet material is pulled down to the pouch bottom 12 as compared with the first embodiment. It has a form. Specifically, it is as follows.

The male member 15a and the female member 15b constituting the opening / closing chuck 15 disposed along one edge of the pouch are heat-sealed on the inner surfaces of the two sheet walls 20 and 30 facing each other. Unlike the first embodiment (FIGS. 1 and 2), the sheet walls 20 and 30 are bonded to each other at the heat seal region 18 even when placed on the upper side of the opening / closing chuck 15. In FIG. 3, the pouch bottom 12 is in an open state. This opening is finally heat-sealed and sealed after the contents are filled.
Therefore, eventually, the entire circumference of the pouch is heat-sealed. However, the heat seal region 18 can be omitted, and therefore, heat seal is performed at least at the peripheral edge (regions 11, 12, and 13 in FIG. 1) other than the one end edge where the opening and closing chuck 15 is disposed. .
The third sheet material 51 is heat-sealed and fixed so that the upper side 51 a is sandwiched between the male member 15 a and the sheet wall 20 at the one end edge where the opening / closing chuck 15 is disposed. Further, at the periphery other than the one end edge (regions 11, 12, and 13 in FIG. 1), the other periphery of the sheet material 51 is heat-sealed and fixed so as to be sandwiched between the two sheet walls 20 and 30. .
Contrary to the illustrated example, the upper side 51a of the third sheet material 51 is heat-sealed and fixed so as to be sandwiched between the female member 15b and the sheet wall 30 at the one end edge where the opening / closing chuck 15 is disposed. Also good.

  As a result of the above configuration, the periphery of the third sheet material 51 is the same as the peripheral seal portion that exists to connect the sheet walls 20 and 30 when the sheet material 51 does not exist. That is, the design property does not deteriorate due to the addition of the third sheet material 51.

  In the manufacturing process of the pouch, as described in the first embodiment, the bottom 12 of the pouch is manufactured without being sealed, and the opening 12 is filled with the contents, and finally, the bottom 12 is filled. To seal. The same applies to the second embodiment. However, as shown in FIG. 3, one sheet wall (the sheet wall 20 in the illustrated example) and the third sheet material 51 are also heat-sealed at the bottom 12. Therefore, food or the like is not filled in the IC tag accommodating portion 50.
