Abstract
The utility model relates to a control by temperature change display sign of lamellar structure, by taking the photograph that the black and white film that has specific identification pattern and the adhesive layer that is adulterated with temperature sensitive liquid crystal material and end dark colour coating are compound to be constituteed, should prevent that counterfeit sign accessible hand touch heaies up or makes sign film surface temperature rise to liquid crystal material color-changing range, demonstrates specific identification pattern promptly, provides an effectual means for the counterfeit prevention of famous commodity, maintains consumer's interests.
Description
The utility model relates to a kind of temperature control display sign of layer structure.
In present commodity economy, often find various counterfeit goods, with bad fill excellent, mix the spurious with the genuine, seriously led consumers in general's interests into a trap, one of them reason is that the local famous brand product packaging label fails to find a kind of effective and efficient manner, and the speculator is had time can bore.
The purpose of this utility model is the anti-personation film label that will provide a kind of hand to touch temperature control or other temperature range variable color demonstration, and energy display sign pattern is present in not reach prevents false effect.
Should anti-personation label dark-coloured coating is compound forms by the black and white film of specific identifier pattern and the adhesive layer that is doped with temperature sensitive liquid crystal material and the end by taking the photograph.Its temperature sensitive liquid crystal color-changing temperature can be set in hand touch temperature variation range, also can be set in other temperature range variable color.
Anti-personation label with said structure feature provides a kind of effective simple anti-section of doing evil through another person for famous-particular-excellent producer, on every box or every bottle of commodity, paste the anti-personation of lastblock label, any consumer is as long as can distinguish this famous commodity specific identifier whether occurred by simple touch or heating and cooling means, thereby winnow truth from falsehood commodity, further illustrate the utility model below in conjunction with description of drawings, provide embodiment simultaneously.
Fig. 1 is anti-false label structure cut-open view.
As shown in the figure, should prevent the stratiform iterative structure densification of false label, form by the black and white film of taking the photograph the specific identifier pattern (1) and adhesive layer (2) that is doped with temperature sensitive liquid material and the dark-coloured coating in the end (3), different commodity can be clapped into black and white film (1) by camera work according to the particular commodity sign that production manufacturer provides, these patterns are general only need to plot black, after the dark-coloured coating in film (1) and adhesive layer (2) and the end (3) is compound, in the temperature range of variable color, the pattern that film (1) shows above presents colored pattern because of liquid crystal color changes, but should anti-false label repeated multiple times use, if make specific pattern into the temperature number of degrees, only need the liquid crystal color temperature is measured through strictness control, also can be made into easy temperature indicating card.The utility model low cost of manufacture, using method is simple, is a kind of comparatively ideal anti-personation label.
Claims (1)
1, a kind of anti-personation label, it is characterized in that by the black and white film of taking the photograph the specific identifier pattern (1) be doped with the dark-coloured coating (3) in the adhesive layer (2) of temperature sensitive liquid crystal material and the end compound composition.
