Description

A kind of anti-counterfeit structure of plastic bottle

Technical field

The present invention relates to a kind of structure of plastic bottle, particularly relate to a kind of anti-counterfeit structure of plastic bottle.

Technical background

Raising along with people's living standard, disposable plastics packed beverage, more and more universal as mineral water, pure water etc., use amount is more and more big, but because the old empty bottle of a beverage bottle source is wide, easily be recovered, and it is low to reclaim price, makes some lawless persons have an opportunity to take advantage of, utilize the old empty bottle that reclaims, palm off former dixie cup, lead the customer into a trap, that gives the customer healthyly brings harm.For addressing the above problem, the producer's employing that has is now installed anti-counterfeiting cover additional and is remedied above-mentioned deficiency on beverage bottle, though brought certain degree of difficulty for the personator who reclaims empty bottle, but because of the anti-counterfeiting cover manufacturing price low, and make simple, antifalse effect is poor, and does not solve the root problem that old beverage bottle is recovered personation.My application number 97209326.5 titles " preventing to be recovered the beverage bottle of personation " though utility model solved disposable technical matters, but because false proof circle is in aggregates with the bottle of beverage bottle during fabrication, whole beverage bottle also cancels simultaneously when false proof circle damages in process of production, cause the finished product rate low, therefore also do not have place in operation so far; In addition, because the bottle strength of material of beverage bottle requires height as the PET material, when opening bottle cap, twist into two parts very difficulty of false proof circle.Therefore, press for a kind of rate height that manufactures a finished product, the plastic bottle anti-counterfeit structure that is easy to open.

Summary of the invention

The objective of the invention is to overcome above-mentioned shortcoming, provide on a kind of bottle neck of the bottle that anti-fake mark is placed beverage bottle, the anti-fake mark of opening on the bottle of back can not restore again, very easily discerns true and false plastic bottle anti-counterfeit structure during purchase.

For this reason, the invention provides a kind of anti-counterfeit structure of plastic bottle, described structure is the easily broken material of property once on the bottle neck of bottle.The anti-counterfeit structure of existing plastic bottle such as mineral water beverage bottle all is to be positioned on the bottle cap, the once easily broken material of property such as disposable decorative cover on bottle cap, and decorative cover is twisted into two parts when opening, and can not restore after twisting into two parts.But easily broken material of the present invention is mounted on the bottle neck of bottle, on the one hand is because the productive costs of bottle is more much higher than bottle cap, is because people's mouth when having a drink is to contact with bottle neck on the bottle on the other hand, rather than contacts with bottle cap.Adopt the disposable cost that both can increase false making of bottle, also can guarantee that people's is healthy simultaneously.

In the anti-counterfeit structure of another kind of plastic bottle provided by the invention, described easily broken material is fixed together with bottle cap after the bottle cap closure, can break the easily broken material that is positioned on the bottle neck when opening bottle cap.Existing bottle cap is false proof to be that the false proof circle on the bottle cap is broken, and the present invention breaks easily broken material on the bottle neck with the unlatching effect of bottle cap.Described bottle cap and easily broken material link together with glue; Also described bottle cap can be linked to each other by hot melt adhesive with easily broken material.Equally also can adopt alternate manner that easily broken material and bottle cap on the bottle neck are fixed.

In the anti-counterfeit structure of another kind of plastic bottle provided by the invention, described easily broken material is the easy-to-draw circle that is positioned on the bottle neck of bottle, because easy-to-draw circle is discerned by the customer when buying and use easily.Opening in the customer for convenience, is easily broken fine rule with the corresponding connecting bridge of bottle neck at the bottom of the circle of described easy-to-draw circle.For the ease of described easy-to-draw circle and bottle cap are fixed, on the inwall of described easy-to-draw circle unidirectional tooth.The individual event tooth opposite with the unidirectional tooth direction of easy-to-draw circle arranged on the described bottle cap, and the rotation by bottle cap just can be fixed together the easy-to-draw circle on bottle cap and the bottle neck so in process of production, and is identical with the canned process of existing production, is convenient to implement.Bottle cap with after bottle neck is fixed together, only need just can judge whether this bottle product was opened by outward appearance intuitively by rotation when the customer buys.In case open, the unidirectional tooth of the easy-to-draw circle on the bottle neck will rotation thereupon under the drive of the unidirectional tooth of bottle cap, the rotation of easy-to-draw circle can be pulled apart the easily broken fine rule that links to each other with bottle neck, and in a single day fine rule is torn and can't restores, and fine rule is torn and shows that this bottle product was unlocked.

In the anti-counterfeit structure of another kind of plastic bottle provided by the invention, described bottle neck and bottle separated to produce be in order to make full use of the performance of both different materials, and reduce production costs.Described bottle neck can link to each other by hot melting way with bottle, and described bottle neck also can link to each other by injection technique with bottle.Certainly, also can adopt other production technology to link to each other.

The anti-counterfeit structure of plastic bottle provided by the invention is compared with existing method and is had the following advantages:

1. intuitive: the customer directly just can judge whether to be unlocked by outward appearance;

2. disposable: in case can't restore after opening;

3. cost is low: it is low to make simple cost, and comparing with existing product increases productive costs hardly.
