Description

[Detailed description of the device]

[001]

[Industrial use field]

 The package with a bar code of the present invention is used for packaging foods, household goods, toys and other products. Especially, it is preferably used in a supermarket.

[002]

[Prior Art]

 Recently, in supermarkets and the like, a system for reading the type and price of a product by attaching a barcode to the package of the product has become widespread. As a method of attaching a barcode to a package of a product, a method of attaching a label with a barcode printed on the package is generally used. However, in this method, in addition to the high price of the label, it is troublesome to attach the label to each package. In addition, a method is also known in which a barcode is printed in advance on a synthetic resin film that covers the packaged object and the package is packaged. However, this method is unsightly as a package because it prevents the bar code printed on the synthetic resin film from seeing through the printed pattern on the package. Further, in this method, the printed portion of the bar code is liable to be damaged during the distribution process of the product, and a bar code reading error often occurs. Further, in the heat-shrinkable package, the bar code printed on the heat-shrinkable film is deformed due to the heat shrinkage of the film, making it unreadable.

[003]

[Problems to be solved by the device]

 The present invention is intended to provide a packaging body with a bar code, which can be packaged at high speed and at a low cost, and which does not impair the appearance of the packaging body and has no reading error due to damage of the bar code during the distribution process. Is. In particular, the present invention aims to provide a wrapping body with a bar code that can be read even in a heat shrinkable wrapping body.

[004]

[Means for Solving the Problems]

 The present invention has taken the following measures to solve the above problems. That is, the packaged object is covered with a transparent synthetic resin film so as to have an envelope-attached overlapping portion, a barcode is printed between the envelope-attached overlapping portions, and the envelope-attached overlapped portion is formed. The packaging body has a tight contact between the mating portions. In particular, it is preferable that the envelop-bonded overlapping portion is closely attached by an electrostatic seal. Further, it is preferable that the bar code printing portion between the envelop pasted overlapping portions is located on a substantially flat portion in the lower portion of the package.

Hereinafter, the present invention will be specifically described with reference to the drawings. FIG. 1 is a perspective view of a package with a bar code according to the present invention in which a confectionery box is packaged as an object to be package, which is turned upside down. The object to be packaged (1) is covered with a synthetic resin film (2) which is a non-shrinkable film. Incidentally, both edge portions (5) and (5 ') of the film form an envelope-attached overlapping portion (3), and the overlapping portions are in close contact with each other. In addition, a bar code (4) printed on the film is provided between the overlappings. The front and rear ends of the packaged object are hermetically sealed by welding seals (6).

FIG. 2 is a perspective view of a package with a bar code of the present invention, which is a heat-shrink-wrapped cup instant noodle as a packaged product, turned upside down. The object to be packaged (1) is heat-shrink packaged using a heat-shrinkable film as the synthetic resin film (2). In addition, both edge portions (5) and (5 ') of the film form an envelope-attached overlapping portion (3), and the overlapping portions are in close contact with each other. In addition, a bar code (4) printed on the film is provided between the overlappings. The front and rear ends of the packaged object are hermetically sealed by fusing seals (7).

FIG. 3 is a schematic cross-sectional view of a portion where a printed barcode is provided between the envelope pasting overlapping portions. The film edges (5) and (5 ') form an envelope-attached overlapping portion (3), and the bar code (4) printed on the film edge is positioned between the overlapping portions. .. The film edge (5) is referred to as the outer film edge, and the film edge (5 ') is referred to as the inner film edge.

As the synthetic resin film of the present invention, a transparent synthetic resin film which has been conventionally used for packaging is used. For example, polyethylene, polypropylene, polystyrene, nylon, polyethylene terephthalate, or vinyl chloride resin is preferably used. Also, a multilayer film made of these resins can be used. Then, a bar code is printed on one edge of each of the films so that when the both edges of the film are overlapped with each other in the form of an envelope, they are located between the overlaps. The barcode may be printed by back printing or front printing. In the case of back-printing, it is necessary that the film edges printed with the bar code are superposed on each other when they are superposed in an envelope pasted state. Further, in the case of front-side printing, it is necessary that the film edges printed with the bar code are internally superposed when they are superposed in an envelope pasting manner. The above-mentioned synthetic resin film may be provided with a printed pattern if necessary. However, when the film edge printed with the bar code on the front side is overlaid, the other film edge without the bar code is not printed and is transparent. It is necessary to be. When the synthetic resin film is a heat-shrinkable film, a bar-coded heat-shrinkable package can be obtained.

As a method for adhering the envelope-bonded overlapped portions, a welding method using heat, an adhering method using an adhesive, or the like is used. However, the one adhered by the electrostatic sealing method does not deform the shape of the barcode and does not hinder the sharpness of the barcode, which is preferable because there are few reading errors.

The bar code between the envelope sticking overlapped portions may come to any part of the packaged object, but it is preferable that the bar code is located on the substantially flat part in the lower part of the packaged object. If the bar code comes to the upper part, which is the front part of the packaged object, not only will the appearance of the package be deteriorated, but it will also be impossible to attach "bonus items" and the like. In addition, if the portion where the barcode is located is a substantially flat portion of the packaged article, the shape of the barcode is not deformed and is easy to read.

[0111]

[Work]

 Since the bar code attached to the package of the present invention has a print sandwiched between the films, the bar code is not damaged by the inner package or the external cardboard box. Is eliminated, and as a result, reading errors are eliminated. Also, the bar code attached to the heat-shrinkable package of the present invention has a print part sandwiched between two films, so that the heat-shrinkability of the part is hindered and the heat-shrinkable package is Sometimes the barcode is less deformed and can be read. When the envelop-bonded overlapping portion is adhered by the electrostatic sealing method, the heating step is not required, and therefore the barcode is not deformed due to heat shrinkage or the like. Also, since no adhesive is applied, the sharpness of the bar code is not lost.

[0112]

[Effect]

 The bar coded package of the present invention can be packaged at high speed and easily, and the bar code can be read without error. In particular, it has become possible to use it for heat-shrink packaging of foods and miscellaneous goods, which was said to be difficult to read barcodes.
