Description

The heat discoloration sign of plastic material or metal material surface

The utility model relates to and a kind ofly adheres to that one deck can vary with temperature and the heat discoloration sign of variable color at plastic material, metal material surface.

Generic container surface or container cover surface are most likely coating plastic packaging film or label, and print title or the pictorial trademark relevant with product on packaging film or label, or directly printed product title or pictorial trademark on bottle cap; Its outer mode of utilizing chromaticity printing makes literal, pattern on packaging film, label or the bottle cap can present the state of polychrome collocation, but these literal, pattern can't vary with temperature and colorific variation.

With the beverage is example, and the consumer does not often know which material has been placed on a period of time in the cold storage refrigerator, have lower temperature, and other beverages has been put just in the refrigerator just into, does not have low-temperature condition; Same situation also can occur in the warming beverage; Therefore if in that a kind of mark that can the displays temperature state can be arranged on the container or on the bottle cap, just then the consumer can obtain sufficient message by this, as the judgement of selecting to buy, and the door that needn't open refrigerator doors or insulation can directly touches container with hand.

The purpose of this utility model is to provide the heat discoloration sign of a kind of plastic material or metal material surface, can vary with temperature and produces change color, needn't touch the temperature that container can be learnt container by change color with hand for the consumer.

In order to achieve the above object, the utility model provides the heat discoloration sign of a kind of plastic material or metal material surface, it is characterized in that: include:

One basic unit;

One attached to the photochromic layer in the basic unit, has at least a color-changing unit that comprises most quantity, and each color-changing unit coats stealthy dyestuff by the temperature controlling agent and colour forming agents is constituted.

The heat discoloration sign of described plastic material or metal material surface, it is characterized in that: the thickness of this photochromic layer is more than the 10 μ m.

And be further to understand architectural feature of the present utility model and purpose, effect, at this measure one preferable feasible embodiment, and cooperate graphic being described in detail as follows.

Graphic part:

Fig. 1 is a structural representation of the present utility model.

Fig. 2 epilimnion structural representation of the present utility model.

Fig. 3 A, 3B are that the utility model is applied to the constitutional diagram on the bottle cap.

Fig. 4 A, 4B are that the utility model is applied to the constitutional diagram on the label.

Fig. 5 is the temperature layer structural representation with two kinds of variations of the present utility model.

See also shown in Fig. 1,2, the heat discoloration sign of plastic material of the present utility model or metal material surface, constituted by a basic unit 11 surface attachment one deck photochromic layers 21, wherein this basic unit can be a plastic material, thermoplastics such as PE, PC, PVC, PET, pearl film for example, or metal material, for example aluminium flake; And these can be used as the material of basic unit 11, mainly are packaging film, the labels that is used for making vessel, container cover or coats container.

This photochromic layer 21 has at least a color-changing unit that comprises most quantity, each color-changing unit is made up of temperature controlling agent 32, stealthy dye well colour forming agents, wherein stealthy dyestuff and colour forming agents are to be together to form chromatic zones 31, and temperature controlling agent 32 then is the outside surface that is coated on chromatic zones 31.More specifically, temperature controlling agent 32 can adopt for example sulfide equal solvent type compound, and stealthy dyestuff can adopt for example electronics trusted compound such as acid phosphoric acid ester; Colour forming agents can adopt for example fluothane electron-like credit quality compound.Colour forming agents in this chromatic zones 31 is a kind of pigment, and the periphery of different pigments is coating different temperature controlling agents 32, and different temperature controlling agents 32 is when being defined within a certain specified temp, this temperature controlling agent 32 will present transparence, when therefore mixing as if the temperature controlling agent 32 that more than one are arranged in photochromic layer 21, its temperature sensor will be looked the design temperature difference of each temperature controlling agent 32 and present different colours, as in some temperature range, some temperature controlling agent 32 presents transparence, and some temperature controlling agent 32 then presents opaque shape.

So when all temperature controlling agents 32 all were transparence, the institute in the chromatic zones 31 all had color to appear, and makes photochromic layer 21 present mixed color and luster; And if the part color is when appearing, when partly color did not appear, then photochromic layer 21 showed another color and lusters.

On the practice, see also shown in Figure 3ly, can utilize bottle cap 42 on the bottle 41 as basic unit, photochromic layer then is printed on bottle cap 42 surfaces with certain literal or pattern, and it is defined as not variable color mark 51; When the temperature of bottle 41 surrounding environment change (or temperature changes in the bottle), then temperature controlling agent (not shown) produces transparency change thereupon, make to be varied to variable color mark 52 with different colours with the not variable color mark 51 that photochromic layer was printed to, can be for the foundation of consumer as identification internal tank or surface temperature.

Certainly, if variable color is set when needing dichromatism above, see also shown in Figure 5, if set temperature is two sections, 21 color-changing units that will comprise two kinds of quantity in this photochromic layer then, each color-changing unit is by temperature controlling agent 32, stealthy dye well color is formed with the temperature controlling agent 32 of two kinds of different set temperature, and all include a stealthy dyestuff and a kind of colour forming agents in each temperature controlling agent 32, before bottle does not reach two kinds of design temperatures, because of temperature controlling agent 32 presents transparence, therefore the pigment that is coated will appear demonstration, make photochromic layer 21 color mixture of two kinds of colors occur, once temperature reaches one kind of design temperature, then this temperature controlling agent 32 will become opaque shape, color be hidden, then rarely seen another color in the photochromic layer 21, so promptly, judge which kind of state of temperature bottle is in by inspecting the different colours that photochromic layer 21 is presented.

Except directly photochromic layer 21 being made printing ink, and be printed on outside bottle cap 42 surfaces of plastics, also can utilize photochromic layer 21 prepared printing ink, directly be printed on the surface of aluminium pot, can reach the recognition effect of alternating temperature variable color equally; See also shown in Figure 4 in addition, but the packaging label 61 of mat bottle 41 appearances is as basic unit, and be printed on the packaging label 61 as printing ink with the photochromic layer (not shown), and literal, the pattern of being printed is defined as not variable color marks the main people 51, and when bottle 41 inside and outside temperature change to some extent, this not variable color mark 51 can produce change color, form variable color mark 52 foundations as consumer's identification temperature.

And above-mentioned photochromic layer 21 is when reality is used, and it greater than 10 μ m, and is the enforcement thickness of the best with the thickness of 20～30 μ m attached to the thickness of basic unit 11.Design of the present utility model in addition also can be made the form of transfer paper, utilize the transfer printing mode with photochromic layer 21 attached on the not specific material; Also can directly the material composition of photochromic layer 21 directly be sneaked into and penetrate among the material, make that the product itself behind the ejection formation has the effect that varies with temperature and produce change color.

In sum, the utility model utilizes substrate surface to adhere to the photochromic layer that is made of temperature controlling agent, colour forming agents and stealthy dyestuff, has the heat discoloration sign that varies with temperature and produce change color with formation, structure innovation not only, have more and obviously to have progressive and practicality for the effect of consumer's identification temperature.
