Abstract

The utility model relates to an anti-theft and anti-counterfeiting mark for products, which is composed of a geometric shape body made of alloy-shaped memory materials after memory treatment. The utility model is made of shape memory materials of CuZnAl alloy, CuAlNi alloy, etc. The alloy materials can be wires or sheets or foil; the geometric shape body can be a line shape, a circular, an oval, a fan shape, a square, a rectangle, a parallelogram, a regular polygon, a trapezoid or a cameo type pattern. The nature of the memory shape is like the nature of passwords. The utility model is flexible and varied, has the advantages of strong anti-theft and anti-counterfeiting functions, simple manufacture and easy use, tests products without instruments, and can be widely used for various products.

Description

Product Theft-proof and anti-counter sign

This product utility model belongs to product Theft-proof and anti-counter sign.

Existing product is antitheft, anti-false sign has two classes.One class is the disposable operative installations of special construction, such as the anti-theft bottle cap of some drinks, can not restore in case take off promptly, prevents that with this illegal businessman from reusing, fake brand-name products.Another kind of is the new holographic laser anti-false sign, it uses optical principle, a certain specific literal or figure are lain in the sign, have only and be under a certain specific illumination or during a certain specific angle when this sign, its implicit literal or figure just can display, seen by the people, distinguish the true and false of this product whereby.These product Theft-proof and anti-counter sign widespread uses on market, what have is copied by others, has lost its original Theft-proof and anti-counter function.

The purpose of this utility model provides a kind of novel anti-theft anti-false sign, and it has had the memory function of password effect, and is so complicated not as computer memory again, can be with the password form to the effect of product performance Theft-proof and anti-counter.

The purpose of this utility model realizes by following proposal.

Geometrical shaped body or embossing pattern that product Theft-proof and anti-counter sign is made after memory is handled by the alloy shape-memory material constitute.This class alloy shape-memory material comprises CuZnAl SMA alloy, CuAlNiSMA alloy, TiNi SMA alloy etc.They can be made into various geometrical shaped bodies after memory is handled, such as, line strip (or filate), circular, oval, fan-shaped, square, rectangle, parallelogram, regular polygon, trapezoidal or embossing pattern (Fig. 1-12), be stated from the commodity.When needs are checked the true and false of these commodity, this Theft-proof and anti-counter sign can be heated, this sign promptly can be remembered, reappear the producer and originally it be remembered when handling and give its shape, thereby reached the purpose of differentiating commodity true and false.

The novel principle of work of this reality provides further combined with description of drawings and embodiment.

Sequence number implication among the figure: 1. line strip, 2. filate, 3. circle, 4. ellipse is 5. fan-shaped, 6. square, 7. rectangle, 8. parallelogram, 9. rhombus, 10. regular polygon, 11. trapezoidal, 12. embossments, the Theft-proof and anti-counter sign of 13. conventional states, 14. during check, be the Theft-proof and anti-counter sign of remember condition after the heating.

The televisor anti-false sign of embodiment 1:CuZnAl SMA alloy head of the horse memory moulding (Figure 13-Figure 14).

Present embodiment is made with CuZnAl SMA alloy.Each tenor of CuZnAl SMA alloy is that Al is 3.5-4.7wt%, and Zn is 24-26.8Wt%, and all the other are the content of Cu.They are smelted into martensitic phase height MS is 30 ℃～100 ℃, contrary martensitic phase height AS be 20 ℃～90 ℃ marmem (Shape MemoryAlloy, SMA).With thin rounded flakes or the paper tinsel of this metal rolled one-tenth thickness＜0.5mm, promptly become the anti-false sign starting material again through memory thermal treatment.With the head of the horse mould its cold compaction is become present embodiment finished product 13 again.The size dimension of this sign can not have meter at random according to the size of televisor.When needs were checked the true and false to televisor, with this anti-false sign heating (about 100 ℃ of heating-up temperature), the head of the horse cameo moulding on the sign promptly disappeared for it, and sign promptly becomes smooth thin discs or circle paper tinsel 14.Its memory effect reaches 90～100%.In the present embodiment, also can reversely design.That is: in advance the starting material memory is heat-treated to the moulding of head of the horse cameo, and then is cold-pressed into smooth circle sheet or circle paper tinsel, be stated from the televisor.When the check televisor true and false, will indicate heating, the cameo moulding of head of the horse promptly can appear on former circle sheet or the circle paper tinsel.

Embodiment 2:CuAlNi SMA alloy silk ring Wine anti-counterfeit sign (Figure 15-17).

Present embodiment adopts existing C uAlNi SMA alloy to make.Getting one section of this alloy silk, is the pentagram shaped as frame through memory thermal treatment, will cold pressing and make annulus, and its cover is affixed on the bottle strength 13.The size dimension of this annulus is decided on bottle.When checking the true and false of this wine, with this annulus filate anti-false sign heat treated, this annulus can become a pentagram 14.In like manner, also can reverse engineer make and check.

Embodiment 3:TiNi SMA alloy rhombus paper tinsel necktie anti-false sign (Figure 18-Figure 19).

The utility model is made with existing TiNi SMA alloy.Get this Alloy Foil and be cut into the rhombus thin slice, through remembering thermal treatment for having " cloud all " printed words markings embossment.Then it is cold-pressed into smooth rhombus paper tinsel 13.This rhombus paper tinsel buckled be stated from the necktie as cloud anti-false sign of board necktie all.When the check necktie true and false, with this rhombus paper tinsel heat treated, the marking embossment 14 of " cloud is all " printed words can appear having on this rhombus paper tinsel, and promptly provable this necktie is a genuine piece.

The utlity model has following features:

1. its shape memory is with cryptographic property, and common people are unknown, thereby the utlity model has Stronger Theft-proof and anti-counter ability.

2. the shape memory that uses as the password design of can following one's bent, flexible and changeable, make illegal it On foot imitative very imitative. Thereby can at any time find and hit fake products.

3. the making that should remember moulding is simple, with low cost, easy to use, and measuring means is very easy, Without instrument and equipment, one is roasting then bright.

Claims

1, a kind of product Theft-proof and anti-counter sign is characterized in that it is the W font made by shape memory alloy material, S font, annulus, pentagram sheet, disk, elliptical piece, fanning strip, quadrilateral sheet, pentagon sheet, hexagon sheet, trapezoidal after memory is handled.

2,, it is characterized in that said alloy shape-memory material is CuZnAl SMA alloy, CuAlNi SMA alloy or TiNi SMA alloy according to the anti-false sign of claim 1.
