JP2000219276A - Film for packaging stacked article - Google Patents

Abstract

PROBLEM TO BE SOLVED: To prevent a bar code from being mistakenly read without degrading the recognizability of an article to be packaged. SOLUTION: In a film 1 for packaging stacked articles in which stacked cans 2 are see-through, a single bar code 5 for the total stacked cans 2 is displayed using a material to transmit the visible beam and absorb the infrared ray. When the stacked cans 2 are packaged by the film 1, an outer circumferential surface of the respective cans 2 can be visually checked without being screened except a part of the bar code 5 while a bar code reader can not read the bar code 3 of each can 2, and only the single bar code 5 of the total cans 2 can be read.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an integrated packaging film provided with a barcode for accumulating and selling canned goods and the like.

[0002]

2. Description of the Related Art A film described in Japanese Utility Model Publication No. 7-1655 is known as this kind of film for integrated packaging. As shown in FIG. 2, the integrated packaging film 1 is
The cans 2 are packaged so that they can be seen through, and on the surface thereof, a number of shielding lines 4 for preventing reading of the bar code 3 attached to each can 2 are printed,
A single bar code 5 is displayed for all cans 2 collected.

[0003] When wrapping with such an integrated packaging film 1, when reading a bar code at a store, the bar code 3 of each can 2 is not erroneously read, and a single bar code 5 for all cans 2 can be read. Can only be read.

[0004]

However, in the integrated packaging film 1 as described above, the design and characters on the outer periphery of the can 2 that consumers refer to when selecting products are indicated by the shielding lines 4.
There is a problem that it is difficult to see because it is obstructed.

SUMMARY OF THE INVENTION It is an object of the present invention to provide an integrated packaging film which has a function of preventing a bar code from being erroneously read, in which the surface of each article can be visually observed without any obstacle.

[0006]

In order to solve the above-mentioned problems, according to the present invention, the stacked articles are packaged so that they can be seen through, and the reading of bar codes attached to the individual articles is prevented by shielding means. In the integrated packaging film that displays a single bar code for all articles, a material that transmits visible light and absorbs infrared light is used as the shielding means.

[0007] When articles are collectively packaged with such an integrated packaging film, the surface of each article can be viewed without obstruction. However, in a bar code reader that reads data by using an infrared reflection pattern, the bar of each article is used. The code can no longer be read and only a single bar code for all items can be read.

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIG. Note that the same reference numerals are given to elements corresponding to the respective elements of the above-described conventional example.

The integrated packaging film 1 is mainly made of a heat-shrinkable film such as polyvinyl chloride, polyethylene, polypropylene, and polystyrene, and has a property of transmitting visible light and absorbing infrared light.

In order to impart such properties, a phosphate-based white crystal powder containing 20% by weight or more of Fe ²⁺ and / or Cu ²⁺ and mainly containing phosphorus pentoxide, or a glass-based powder material May be coated or vapor-deposited on a film material, or may be mixed during the production stage.

Further, as a material for absorbing infrared rays, interbium phosphate, lithium aluminum composite hydroxide salt, magnesium aluminum composite hydroxide salt, composite hydroxide condensed silicate, or the like may be used.

[0012] The stacked packaging film 1 is brought into close contact with the outer periphery of the stacked cans 2 with heat shrinkage, and these cans 2 are packaged in an integrated state. When the bar code 5 is displayed by printing or pasting, the outer peripheral surface of each can 2 can be visually observed without interruption except for the bar code 5, but in the bar code reader, the outer surface of each can 2 is attached to each can 2. Bar code 3 cannot be read, and only a single bar code 5 for all cans 2 can be read.

Therefore, it is possible to prevent the barcode from being erroneously read without lowering the product recognition at the store.

Further, in packaging, it is not necessary to align the bar codes 3 of the individual cans 2 in the vertical direction, so that the packaging can be easily performed.

[0015]

As described above, the integrated packaging film according to the present invention uses a transparent and infrared absorbing material.
Since a single barcode for all articles is displayed on the surface, the surface of the stacked and packaged articles is visible, but the barcode reader is prevented from reading the barcode of each individual article, Only a single bar code can be read for all articles, and misreading of bar codes can be prevented without lowering the recognizability of articles.

Claims (1)

[Claims] 1. An integrated packaging for packaging an integrated article so that it can be seen through, a bar code attached to each article being prevented from being read by a shielding means, and displaying a single bar code for all these articles. In the film, a material for transmitting visible light and absorbing infrared light is used as the shielding means.
