DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a so-called bar code capable of optically reading the type and standard of a product.
By providing normal barcodes in an intersecting manner, reading can be performed from two directions in the vertical and horizontal directions. In particular, normal barcodes or the above-described cross barcodes are mainly made of porous materials such as glass and plastic products. It is intended to provide an effective product for use in a container of a product consisting of:

[0002] In recent years, a bar code which has been widely used for optical knowledge of various products has a base color of light reflection, and a number of black or dark blue equilibrium lines are printed on the base color in accordance with international standards. Light reflection bands and light collection bands capable of absorbing light were alternately formed. This is described in more detail in FIG.
As shown in (1), a normal bar code (a) is made of white or plain paper or the like as a base (b), and leaving a certain reflection area (d) and (d) on both sides, which is a light-collecting color of black or black. By printing a large number of light-gathering bands (C) at a predetermined interval and required thickness using dark blue printing ink, the surface can be scanned with, for example, a hand scanner or the like, and by country, producer, variety, There is widely known a device capable of optically reading a part number standard or the like.

[0003] Therefore, if a bar code is to be applied to a product container itself made of a porous glass or plastic material, even if a normal bar code is directly printed on the surface of the product, the reflection band is not applied. The reading was impossible because the underlying portion, which should be opaque, also transmitted light.
Therefore, conventionally, a predetermined barcode is printed on rectangular reflective plain paper having a required length as shown in FIG.
Means of sticking these four sides to the surface of the porous container or printing a base of a reflective color in a rectangular shape at an appropriate position of the commodity container in advance and then overprinting a normal bar code are used. It was.

[0004]

As described above, according to the prior art, when a bar code is used for a container whose main body is made of a porous material, an ordinary bar code is used for the above-described reason. Because it was not possible to print on the container surface as it was, it not only required the labor of sticking a barcode printed on another sheet or overprinting, but also exposing paper pieces and undercolor on the surface of the product, especially for beverages For design-oriented glass bottles and plastic containers that contain liquids,
Both appearance and design were not favorable.

[0005]

In view of such circumstances,
The present inventor has conducted intensive studies to develop an effective use of a barcode for a container made of a transparent material such as the above-mentioned glass or plastic. Of the normal barcode printed on
This solves the problem seen in the conventional barcode by means of printing only the area corresponding to the reflection band directly on the surface of the translucent container.

In addition, only the printing of the area corresponding to the reflection band is performed.
Print a bar code in advance in colorless or transparent film made of, which also used means that attached to the appropriate surface of the transparent envelope.

That is, the bar code reading start position is
The first and last light-gathering bands of regular barcodes designed according to certain standards to be clearly read by the canner
The present invention provides a technique of providing a reflection area of at least 5 mm at positions corresponding to both end sides and printing directly on the surface of a light-transmitting container or a transparent film.

[0008]

The bar code according to the present invention according to the above-described configuration has a light-transmitting material surface as a base, but is less than a normal bar code.
Print only the reflection band, which is the area where light is easily reflected
The light transmissive container surface that is hard to reflect light
This is a corresponding area, and has a special effect that optical identification can be performed as it is by the same scanner as before. In addition, by providing a reflection area of a fixed length on both side ends of the bar code, an effect that the reading start and end positions of the scanner can be accurately identified can be obtained.

[0009]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The construction of the present invention will be described in more detail with reference to the embodiments shown in the drawings. FIG. 1 shows a light-transmitting container disclosed in the present invention.
An embodiment in which a bar code for a container is applied to a black glass container for accommodating a certain liquid beverage (however, the figure is made by inverting black and white for the sake of clarity of the drawing),
Is a container body, 2 is a barcode attached to an appropriate position on the surface of the container, 3 is a reflection band printed on the base, 4 is a light-collecting band on which the base is exposed (no printing), and 5 is a light-collecting band. Barco
And a reflection area having a length of at least 5 mm and provided on the outer side in contact with both ends of the light-gathering band 4 of the gate 2 .

FIG. 2 shows another embodiment of the present invention, in which a bar code 2 ' similar to that of the above embodiment is provided on one surface of a normally colorless and transparent film 1', and fixed bar codes are provided on both side ends thereof. The long reflective area 3 'is printed with a reflective ink and attached to an appropriate position of the translucent container, or the transparent film 1' is attached to the container by a pre-stretched tubular film. Then, it is heated and shrink-wrapped.

In this case, in FIG. 3, the white portion of the illustrated normal bar code (a) is colored and printed to form the reflection band 3, while the black line portion is not printed and becomes the light collection band 4.

The bar code 2 'of the present invention is not limited to the glass container described above, but can be applied to all containers made of a translucent material such as plastic. It has nothing to do with light and dark.

Further, in the present invention, as for the color of the line of the bar code printed on the container or the transparent film, many colors can be freely selected from reflective inks.

In addition to the above, the bar code 2.2 'of the present invention is provided.
If the length of the reflection area 5.5 or 5'.5 'attached to both sides of the scanner is 3 mm or less, the reading accuracy of the scanner decreases. Therefore, it is preferable to set the reflection area to about 5 mm in view of the safety factor.

[0015]

As described above, according to the present invention, a bar code is directly printed on a container or a bag of a product made of a light-transmitting material such as glass or plastic, or when a bar code is printed on a transparent film separately, a conventional method is used. Equivalent to the reflection band of a barcode
The area to be printed as it is, and
Reflection areas are provided at both ends of the printing belt, and barcode paper printed as in the past can be attached to the surface of the container, or a normal barcode can be overprinted on a base printed beforehand. This is a novel invention that is extremely useful not only to save labor, but also to enhance the form and design of the product.

Further, the color of the barcode of the present invention is not limited to black or dark blue as in the case of the conventional barcode, and the color of the printed barcode is higher than that of the conventional barcode.
If the ink is highly reflective, it can be used in red,
You can select any color such as yellow, and you can obtain barcodes that match the shape and design of the product, such as shortening the bar length enough to make the whole elongated and strip-shaped. This is extremely effective.

Further, the bar code printed on the transparent film has a feature that the same result as that of the bar code directly printed on various containers or the like using the same can be obtained.
