Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a bag material, and more particularly, to a bag material in which two bags having different shapes or sizes are formed when cut off, and to a material for displaying an advertisement or the like on the surface of the bag material.
[0002]
[Prior art]
2. Description of the Related Art In recent years, most stores in Japan, such as supermarkets, provide a service of distributing shopping bags (hereinafter, referred to as "shopping bags") made of polyethylene or the like to shoppers in order to put purchased products.
The above-mentioned shopping bags are often installed near cash registers so that cashiers can easily distribute them.Those that have hook holes for convenient installation, and separation lines near the insertion holes for easier removal are provided. There were things that we could tear off.
As a conventional technique relating to the shopping bag provided with the separation line, for example, there is a technique disclosed in the following patent document.
[0003]
[Patent Document 1]
Japanese Patent Application Laid-Open No. 13-106241
[Problems to be solved by the invention]
However, as shown in Patent Literature 1, when an attachment portion provided with an insertion hole is formed in an ear shape, a portion cut off in a step of processing a tubular film into a handbag is discarded as dust.
Also, at stores where plastic shopping bags are distributed, the remaining attachment section after separation has no utility value, leading to an increase in garbage.
The above part was not only garbage but also waste of resources.
[0005]
In addition, in Japan, the business custom of distributing shopping bags after purchasing products has become established, but in many cases, shopping bags are simply discarded after one-time use.
As a result, various resources are wastefully consumed to produce the shopping bags, and furthermore, energy and the like required for disposal such as incineration of the waste shopping bags are wasted. In addition, the emitted CO2 and the like were one of the causes of causing air pollution.
In order to overcome this situation, in recent years, the government has stipulated the Containers and Packaging Recycling Law, obliging traders to recycle containers and packaging, and local governments also impose taxes on plastic shopping bags. There are also places that determine such things. Furthermore, there are also individuals who do not receive shopping bags by bringing containers such as bags and baskets (hereinafter referred to as "my bags") for storing purchased products.
Thus, the need to reduce containers and packaging, including plastic bags, has been recognized by society.
[0006]
On the other hand, if the store purchases shopping bags and bears the cost of recycling it, the store will be forced to double the burden.
In order to reduce the burden, the store side should reduce the burden of taxes etc. according to the above laws and regulations or convert it to the customer side, such as paying for shopping bags or enlightening activities to bring my bag at the store Therefore, it is conceivable to take a method of reducing the amount of shopping bags to be distributed.
However, there are still a small number of customers who bring their own bags in consideration of environmental issues, and the majority of shoppers, such as those who normally return to work, do not carry bulky my bags and use shopping bags. Often. Therefore, a method of charging a shopping bag or a method of forcing the user to bring a my bag may not be able to obtain the understanding of the customer, which may lead to a separation from the customer.
As a result, in many cases, shops that have or willing to reduce the shopping bags distribute the shopping bags at stores at their own expense.
[0007]
(Object of the invention)

(Operation)
FIG. 2 is an explanatory view of a state where the bag material is separated into two,
FIG. 3 is a perspective view of a handbag,
FIG. 4 is a perspective view of the pouch.
The operation of the bag material according to the first embodiment will be described with reference to FIGS.
[0032]
The bag material A shown in FIG. 2 shows a state where the handbag 1 and the small bag 2 are separated along the formed separation line 15.
[0033]
Please refer to FIG.
The remaining portion that has been cut off along the separating line 15 is the gusseted carrying bag 1 having the carrying portion 17. Note that the handbag 1 can be stored without bulk by storing it in a small bag 2 when not in use.
[0034]
Please refer to FIG.
The portion cut off from the bag material A is closed at the side and bottom by forming the above-mentioned seal portions 12 and 14, forming a bag shape, and forming the small bag 2 having the opening 22.

The holding part 21 is formed of a part 21 of the gusset to be cut off, and is formed so as to be connected to the opening 22 at a part of the seal parts 12 and 14 on the inner side of the separation line which is related to the gusset.
[0035]
FIG. 5 is a front view of the bag material according to the second embodiment. The operation of the bag material according to the second embodiment will be described with reference to FIG. Note that the same or equivalent parts as the bag material A are denoted by the same reference numerals, and description thereof will be omitted.
The bag material B shown in FIG. 5 has substantially the same structure as the bag material A shown in FIG. 1, except that the size of the bag material B is a rectangular sheet having a length of 36 cm and a width of 26 cm (so-called B4 size) and a newspaper. The difference is that it is slightly smaller so that it can be easily inserted as an advertisement.
The size of the bag material is not limited to the B4 size, and a large-sized bag material may be folded into two and folded.
[0036]
On the bag material B, an advertisement 30, a barcode 31, and an attachment table 33 on which special sale information such as a supermarket is written are printed, and are used as a newspaper insert advertisement. Since the bag material B before being separated into the handbag 1 and the small bag 2 is a closed bag material, the bag material B is well united and easily folded into a newspaper.
The method of distributing the bag material B indicating the advertisement 30 or the like is not limited to the newspaper insertion advertisement, and may be, for example, distribution of the bag material at a store or a street.
[0037]
In the barcode 31 printed on the carrying portion 17 of the bag material B, information such as the expiration date of the advertisement of the store and the discount target product is input instead of the product information or the like defined by JIS.
Before or after the transaction, preferential measures such as reading the input information with a barcode reader at the store and discounting the price of a specific product are taken. As a result, it is possible to differentiate the customer who brought the shopping bag 1 on which the advertisement is written from the other customers, and to promote the bringing of the bag and the reuse of the bag.
[0038]
An attachment table 32 is printed on the small bag 2 of the bag material B, and a shopping customer gives a point sticker and attaches the point sticker to the attachment section 33 related to the attachment table 32. This saves the trouble of creating and distributing a new mount.
Also, if a certain number of point stickers are accumulated, it is possible to promote return visits by giving preferential measures such as exchanging for a shopping ticket.
[0039]
The bag material B on which an advertisement or the like is printed can be used as a bag, unlike a conventional paper-made insertion advertisement, so that it can be prevented from becoming garbage as it is, and is preferable from the viewpoint of resource saving.
On the store side, the garbage in the attachment section does not come out like a conventional shopping bag, which leads to a reduction in garbage.
In addition, by giving benefits such as discounts to customers who use the handbag 1 with an advertisement etc. according to the present invention, the number of customers who bring the bags increases and the effect of reducing the amount of shopping bags distributed at the store is expected. Therefore, resource saving and cost saving can be expected.
Furthermore, the shopping bags are usually thrown away, but if the discount benefits are repeatedly obtained during the period, the reuse of the shopping bags can be expected, leading to resource and cost savings. .
On the other hand, not only conventional fixed customers but also customers who expect discounts and other benefits can expect an increase in sales.
[0040]
In the case where the bag material is formed larger than B4, the bag material is folded in two at the top and bottom, and a sealing portion is provided at two longitudinal edges in parallel in the width direction, and a separation line is provided between the sealing portions (FIG. Is omitted), the upper and lower edges of the bag material are closed to improve the unity, which is suitable for the operation of folding into a newspaper by a machine.
Instead of the heat sealing, the edge on the gusset side may be closed in the longitudinal direction with an adhesive tape. The adhesive tape may be formed so that a separation line is provided at a central portion in the longitudinal direction so that the adhesive tape can be separated.
The closed bag material is cut off along the separation line, or peel off the adhesive tape, or cut open with scissors, cutter, etc. in the longitudinal direction, or cut off along the separation line provided on the adhesive tape, It is configured to be the bag material shown in FIG.
[0041]
