Abstract

The utility model relates to a bar code used in the management of the bar codes of articles. The utility model is mainly composed of a base and a plurality of metal thin strips, wherein, the base is made from plastics thin film of polyamine resin, and the metal thin strips with different thickness are fixedly arranged on the thin film base at unequal intervals. The utility model has the advantages that durability is good, adaptability is strong, and the utility model can still be read under the condition of contaminated and coated bar codes, being suitable for various articles. The utility model can be made into invisible bar codes with the function of secrecy so that imitation and counterfeit are effectively prevented. The utility model is particularly suitable for use by secrecy papers and products and high quality well-known goods.

Description

The thin film type metal bar code

The utility model relates to the bar code of using in the article bar code management.

Bar code management has been widely used in every profession and trade.Existing bar code is seen for the paper printing sign indicating number more, promptly does carrier by papery, and the bar code symbol that adopts printing process that some width are differed, do not wait at interval is printed on the paper carrier and constitutes.Utilize the colour difference between carrier and the bar code symbol, distinguish by optical scanner.This is the bar code poor durability of carrier with the papery, wearing and tearing in use easily take place and is subjected to the erosion of wind and rain and causes the incompleteness of bar code symbol very directly to disappear; Perhaps covered and be difficult to cleaning, cause recognition difficulty by greasy dirt, dust; Perhaps polluted and can't distinguish at all by paint, coating class.This is that another deficiency of the paper printing bar code of feature is to have under the condition of light and could distinguish with the colour difference, simultaneously, outside guaranteeing that its bar code of recognition must be exposed to, is easily forged by imitated, and confidentiality is poor.

The purpose of this utility model is that existing paper printing bar code is improved, and a kind of good endurance is provided, and is not afraid of to cover, pollute and distinguish the convenient thin film type metal bar code that is easy to.

The thin film type metal bar code that realizes the utility model purpose is made of carrier substrates and the bar code symbol that is arranged on the carrier substrates, and described carrier substrate is a polyamine fat plastic sheeting, and the bar code symbol is web.Described web can be the foil of sheet iron and so on, adopts modes such as stickup, mold pressing to make it to be fixed on the polyamine membrane of lipoprotein, also metal powder directly can be bonded on the film substrate to constitute.When the color of the color of the web that is adopted and film substrate was inconsistent, this thin film type metal bar code can be distinguished out the information of representative for the optical scanner of existing reading paper printing bar code.For the needs of maintaining secrecy; metallic barcode and film substrate can be made same color; perhaps on the surface of substrate and bar code, apply the nonmetal overcover of one deck; or one deck on-metallic protective coating is set with the regional metallic barcode that protects the latent type of formation that hides of bar code, utilize electromagnetism class scanner to distinguish out the information of latent type bar code representative.To covered bar codes such as pollution and oily trowel used for plasterings, or, also can utilize electromagnetism class scanner to distinguish in the occasion that lacks light source.

The utility model is compared with existing paper printing bar code, has the following advantages:

1, good endurance: the erosion that the plastic sheeting substrate more can be resisted wind and rain than paper substrates, web more can tolerate the irradiation of sunlight and the wearing and tearing in the use etc. than the bar code symbol of printing;

2, adaptability is strong: because metallic barcode can adopt the electromagnetic scanning device to distinguish, so the pollution that the utility model is not afraid of dirty trowel used for plastering, dust, mud etc. covers, also need not light source requirements when reading;

3, can maintain secrecy: since the utility model can make latent type and do not influence recognition, therefore have security performance, can prevent from effectively imitated the forgery to be particularly suitable for the use of famous-brand and high-quality goods and the use of secret certificate.Simultaneously, the bar code after covered also can make prolong its serviceable life.

Provide embodiment below in conjunction with accompanying drawing.

Fig. 1 is a front view of the present utility model

Fig. 2 is the vertical view of Fig. 1

Fig. 3 is the structural representation of embodiment 2

Embodiment 1:

As shown in Figure 1, 2, this thin film type metal bar code is made of substrate 1 and the metallic barcode symbol 2 that sticks in this substrate 1.Its substrate 1 is served as by the polyamine membrane of lipoprotein, and metallic barcode symbol 2 is served as by sheet iron.With sheet iron width and the different information of interval various combination representative.

Embodiment 2:

As shown in Figure 3, the formation of present embodiment is to have set up one deck overcover 3 on the substrate of embodiment 1 and metallic barcode.Constituted a kind of latent type metallic barcode thus.This overcover 3 can adopt the coating class directly to be coated on the metallic barcode surface, also the film of a non-transparency can be covered in its surface.

Claims

1, a kind of thin film type metal bar code is made of carrier substrates and the bar code symbol that the some width that are arranged on the carrier substrates differ, do not wait at interval, it is characterized in that described carrier substrates is that polyamine fat plastic sheeting, bar code symbol are web.

2, thin film type metal bar code as claimed in claim 1 is characterized in that described web is the sheet iron sheet that is bonded on the film substrate.

3, thin film type metal bar code as claimed in claim 1 is characterized in that described web is made of the iron powder that directly is bonded on the film substrate.

4, thin film type metal bar code as claimed in claim 1 is characterized in that also being coated with the nonmetal overcover of one deck on the surface of described film substrate and web.
