JP5487554B2 - Pouch with IC tag - Google Patents

Description

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

  Recently, it has been proposed to embed an IC tag in daily commodities, foodstuffs, 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.

  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 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 is a pouch in which the shape in plan view constituting the accommodation space is a rectangular shape between two opposing rectangular sheet walls.
Of the four sides constituting the rectangular shape, the two seat walls are joined in a seal region that forms one side on the bottom side and a seal region that forms two sides on both sides, and a rectangular shape is formed between the two sheet walls. It joins in the state which pinched | interposed the shape 3rd sheet | seat material.
The dimension of the third sheet material in the pouch height direction is made shorter than the height dimension of the two sheet walls, and the dimension of the third sheet material in the pouch width direction is set to the pouch of the two sheet walls. It is the same as the width dimension.
The third sheet material has a sealing layer on both surfaces thereof, and a baffle plate is inserted between the third sheet material and one of the sheet walls in the heat sealing step, thereby the sheet. Bonding to the wall is prevented, and the upper and lower sides are joined to the other sheet wall.
Thereby, between the wall surface of the other sheet wall and the third sheet material facing the wall surface, the pouch height direction dimension is smaller than that of the accommodation space, and the pouch width direction dimension is the accommodation space. An accommodating part that is the same as that of No. 1 is configured, and an IC tag is accommodated in the accommodating part.

In addition, the present invention provides a pouch with an IC tag having the following characteristics. The pouch with an IC tag of the present invention is a pouch in which the shape in plan view constituting the accommodation space is a rectangular shape between two opposing rectangular sheet walls.
Of the four sides constituting the rectangular shape, the two seat walls are joined in a seal region that forms one side on the bottom side and a seal region that forms two sides on both sides, and a rectangular shape is formed between the two sheet walls. It joins in the state which pinched | interposed the shape 3rd sheet | seat material.
The dimension of the third sheet material in the pouch height direction is made shorter than the height dimension of the two sheet walls, and the dimension of the third sheet material in the pouch width direction is set to the pouch of the two sheet walls. By making the dimension slightly shorter than the dimension in the width direction, both end edges of the third sheet material in the pouch width direction are positioned inside the sealing region that forms two sides on the both side portions.
The third sheet material has a sealing layer only on one side, and is joined to one of the sheet walls at the upper side and the lower side.
Accordingly, the pouch height direction dimension is smaller than that of the accommodation space between the wall surface of the one sheet wall and the third sheet material facing the wall surface, and the pouch width direction dimension is the accommodation space. An accommodating part that is the same as that of No. 1 is configured, and an IC tag is accommodated in the accommodating part.

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. 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.

  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 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 with reference to the second embodiment of FIG. 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.

≪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. Is a barrier layer, basically, may be used as long as deposited film formed by depositing a metal or metal oxide, as its material, for example silicon (Si), aluminum (Al), magnesium (Mg) , Metal such as calcium (Ca), potassium (K), tin (Sn), sodium (Na), boron (B), titanium (Ti), lead (Pb), zirconium (Zr), yttrium (Y) or the like Oxides 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 seal areas 11 and 13, sheet walls 20 and 30 are heat sealed directly.
