Abstract

PURPOSE:To obtain the bar code display body which is usable in a field by adhering a bar code formation body which has a cohesive layer on one surface of a colored plastic film onto a separator across the cohesive layer, and peeling the separator without peeling a bar code pattern together. CONSTITUTION:The bar code display body consists of the separator 1, the bar code pattern 2, and a cohesive sheet 3. The bar code pattern 2 is formed of the bar code formation body which has the cohesive layer 21 on one surface of the colored plastic film 22. The bar code formation body is obtained by applying an pressure sensitive adhesive over one surface of the colored film which is superior in weatherability, water resistance, and size stability. The cohesive sheet 3 is a transparent cohesive sheet formed by providing the cohesive layer to a thin leaf body with superior self-supporting performance. The bar code display body is adhered to an object body across the cohesive layer of the bar code pattern exposed by peeling the separator.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a barcode display body suitable for outdoor use.

As distribution management using conventional technology barcodes becomes widespread, in the transportation industry, in addition to the conventional management of cargo units, management of containers and vehicles is being considered for the purpose of managing transportation history, etc. There is a need for a barcode display body that can withstand use in, for example, exposure to rain, and has excellent abrasion resistance and stain resistance.

Conventionally, paper labels have been known as barcode display bodies. However, there was a problem that it lacked durability and could not be used outdoors. Therefore, the current situation is to use paint to directly write the necessary information on vehicles, etc., and visually identify it. However, problems have been pointed out, such as the amount of information that can be recorded is small, it is easy to make mistakes in identification, and it takes a lot of effort to erase old identification marks and replace them with new ones.

Problems to be Solved by the Invention An object of the present invention is to develop a device that is highly durable, can withstand outdoor use, and is easy to install and remove.

Means for Solving the Problems The present invention provides a barcode pattern formed of a barcode forming body having an adhesive layer on one side of a colored plastic film that is weather-resistant, water-resistant, and has excellent dimensional stability. A barcode display body, characterized in that the separator is adhered onto the separator, an adhesive sheet is adhered onto the barcode pattern, and the separator can be peeled off without accompanying the barcode pattern. This is what we provide.

Example The barcode display body of the present invention is illustrated in FIG.

1 is a separator, 2 is a barcode pattern, and 3 is an adhesive sheet.

As the separator, an appropriate material such as paper or plastic film treated with a release agent may be used. It is formed of a barcode forming body having an adhesive layer 21. Such a barcode forming body can be obtained by attaching an adhesive to one side of a suitably colored film having excellent weather resistance, water resistance, and dimensional stability. Plastic films with excellent properties include, for example, polyvinyl chloride-based, polyester-based, and fluororesin-based films, which also have excellent heat resistance and chemical resistance. Film thickness is 6-300μm
is common, but not limited to this. The purpose of coloring the film is to improve the contrast between the barcode pattern and the adherend, and the color may be arbitrary. It is generally considered to be a color other than red. The colored plastic film may be formed by any suitable method, such as adding pigments, dyes, etc. to plastic and forming the film, or applying a coloring agent to the plastic film. Note that the contrast between the barcode pattern and the adherend can also be improved by color manipulation on the adherend side, such as by adhering a colored sheet. Moreover, such a colored sheet can also be incorporated into the barcode display body of the present invention. An example is shown in Figure 2. This is the separator l
A colored sheet 5 is interposed between the barcode pattern 2 and the barcode pattern 2. Note that 4 is an adhesive layer for adhering the colored sheet 5 to which the barcode pattern 2 is adhered to an adherend.

The barcode pattern can be formed, for example, by cutting a barcode forming body into appropriate dimensions to produce pattern forming pieces, and arranging the pieces in a predetermined information form. The barcode pattern to be formed is arbitrary. A barcode pattern preferred for outdoor use is one in which two types of pattern forming elements, wide and narrow, are arranged at two predetermined intervals.

As the adhesive sheet, an appropriate adhesive sheet may be used, such as a film or sheet made of Plastirag, which is a thin film with excellent self-supporting properties and an adhesive layer provided thereon, to facilitate positioning when adhering to an adherend. For this reason, a transparent adhesive sheet is generally used.

The barcode display body of the present invention is formed so that the adhesive force can be adjusted so that the separator can be peeled off while the adhesive sheet is adhered onto the barcode pattern. The form and dimensions of the barcode display body may be determined as appropriate depending on the purpose of use, and large-sized barcode display bodies can be easily produced. Incidentally, when attaching it to a container or freight vehicle, it is preferable to form it to a size of about 5 to 20 centimeters in length and 15 to 50 centimeters in width from the viewpoint of confirmation of the mounting position and high-speed reading by a scanner such as a barcode reader.

The barcode display body can be attached to the adherend through the adhesive layer of the barcode pattern exposed by peeling off the separator or the adhesive layer of the colored sheet.

After adhesion, the adhesive sheet is peeled off from the barcode pattern if necessary. If the adhesive sheet deteriorates or easily discolors, it is preferable to peel it off.

The application of the Barcode V system in the field of transportation and the like using the barcode display body of the present invention can be carried out, for example, as follows. In other words, a barcode display body having a barcode pattern in the form of information necessary for managing transportation history, etc. is formed, and the barcode pattern is adhesively applied to the side surface of an adherend such as a container or freight vehicle. This can be done by reading with a code reader or the like.

Example 1 A barcode forming body was prepared by providing an acrylic adhesive layer on one side of a black vinyl chloride film having a tensile strength of 1.5 kg/I Omm, an elongation of 40%, and a tear strength of 55 to 60 g, with a length of 100 mm and a width of 100 mm. Cut into 0.9 mm or 2.2 mm pieces to obtain two types of pattern-forming pieces, and adhere them on the surface of a paper separator treated with a silicone release agent at intervals of 2 mm or 4 mm to form a predetermined bar code. After forming the pattern (+8 digits), letters and numbers with the same information as the barcode were glued to the human reader pull area at the bottom. The letters, numbers, etc. were formed using the barcode forming body described above. Next, a weakly adhesive acrylic pressure-sensitive adhesive sheet was adhered and coated onto the display portion such as the barcode pattern, thereby forming a barcode display body measuring 13 cm in length and 38 cm in width.

The separator was peeled off from the barcode display body and adhered to a predetermined position on the side of a white container via the exposed adhesive layer, the adhesive sheet was peeled off, and the barcode pattern was read with a laser scanner. , could be read accurately. Furthermore, the applied barcode pattern had sufficient strength, withstood exposure to rain, and did not discolor. Furthermore, after being left outdoors for a week, the applied barcode pattern was peeled off from the container and was able to be peeled off smoothly.

Effects of the Invention According to the barcode display body of the present invention, a barcode pattern that can be used outdoors can be easily applied to an adherend by an operation such as adhering an adhesive sheet, and the applied barcode pattern can be easily applied to an adherend. can be removed more easily than the adherend. Therefore, it is possible to manage each container using barcodes in the field of transportation and the like.
