1, the quality of suncream own how, how isolates ultraviolet effect;

2, when use suncream, use which kind of SPF(Sun Protection Factor SPF (sun protection factor)) suncream;

3, smear and how long once can protect.

Content above ordinary consumer is understood is only understood on the operation instructions of suncream at present, perhaps understands from related detection mechanism, thereby consumer's right to know and result of use are had a greatly reduced quality.At present, the consumer does not also have valid approach to understand how which kind of suncream of use uses suncream.

Summary of the invention

Can just can know as how use suncream, use what suncream, understand the preventing ultraviolet effect of suncream that the utility model provides a kind of suncream detection use indicator by simple means in order to make ordinary consumer.

The technical scheme that the present utility model purpose adopts is: a kind of suncream detects and uses indicator; comprise the dark more UV-radiation-sensitive off-color material of the strong more variable color of ultraviolet ray; described UV-radiation-sensitive off-color material is coated with and prints on the matrix that is provided with warning color, covers the diaphragm of layer of transparent on described UV-radiation-sensitive off-color material coating.

Further, above-mentioned a kind of suncream detects and uses in the indicator: described warning color and described UV-radiation-sensitive off-color material expose the color that is presented to the open air under the ultraviolet ray of respective strengths identical.

Further, above-mentioned a kind of suncream detects and uses in the indicator: described UV-radiation-sensitive off-color material is spirooxazine photochromic compound (spirooxazines).

In the technical solution of the utility model, owing to be the UV-radiation-sensitive off-color material to be coated be imprinted between the matrix and transparent protective film that is provided with warning color, can whether strong in order to detect solar ultraviolet by observing UV-radiation-sensitive off-color material variable color depth under ultraviolet ray, the contrast warning color, whether consumption guidance person uses suncream; Also can outside transparent protective film, smear suncream; smearing suncream by observation stops and absorbs behind the solar ultraviolet the whether variable color under solar ultraviolet of UV-radiation-sensitive off-color material; in order to detect the preventing ultraviolet effect of suncream; how consumption guidance person uses suncream; easy to use, testing result is reliable.

Below in conjunction with accompanying drawing the utility model is described in detail.

Description of drawings

Accompanying drawing 1 is the utility model sectional view.

In the accompanying drawing, 1, matrix, 2, UV-radiation-sensitive off-color material, 3, transparent protective film.

Embodiment

Embodiment 1 as shown in Figure 1, present embodiment is a kind of by uitraviolet intensity under the observation UV-radiation-sensitive off-color material coating color change-detection sunray or after covering one deck suncream, the suncream of the preventing ultraviolet effect by observation UV-radiation-sensitive off-color material coating color change-detection suncream detects and uses indicator, the profile of present embodiment is bar shaped, also can make a circle or other all styles of, be a kind of aid that people use when using suncream.Whether desirable, the suncream of which kind of spf value is used in indication if can be used for detecting the suncream sun-proof result, use suncream and how long use suncream one time under assorted petty situation.As shown in Figure 1: the suncream of present embodiment detects and uses indicator, comprising: matrix, three layers of transformation region and diaphragm.Wherein matrix 1 is made by plastics or paper, is that whole suncream detects the carrier that uses indicator, is coated with the seal warning color on matrix 1.Warning color is a standard color block that pre-sets, and warning color is identical with the following color that is presented of ultraviolet ray that the UV-radiation-sensitive off-color material is exposed to respective strengths, illustrates when use suncream.When transformation region variable color degree of depth under the ultraviolet ray irradiation reaches or exceeds this warning color, show that uitraviolet intensity is stronger, should use suncream; Transformation region is positioned on the matrix 1, covers a part or the whole substrate 1 of matrix 1.Transformation region is to be coated with one deck UV-radiation-sensitive off-color material 2 that is imprinted on the matrix 1, Wei spirooxazine photochromic compound (spirooxazines), variable color under ultraviolet ray irradiation, the strong more variable color of ultraviolet ray is dark more.Smear suncream at transformation region, observe ultraviolet ray and stopped by suncream whether the variable color that absorbs the back transformation region shoals, and whether can detect the suncream sun-proof result desirable, and the suncream of which kind of spf value is used in indication; On the person, smear in the suncream, also smear suncream at transformation region, ultraviolet ray by suncream stop absorb back transformation region nondiscolouring or variable color more shallow, how long observe that the back transformation region begins variable color or darkens, how long indication uses suncream one time.On UV-radiation-sensitive off-color material 2, cover the diaphragm 3 of layer of transparent, be used to protect the interior UV-radiation-sensitive off-color material of transformation region to avoid suncream dirty or that smear because of the contact absorption and lost efficacy.Diaphragm 3 is plastic sheetings of layer of transparent, is covered on the transformation region.During use, suncream spreads upon on the diaphragm, avoids transformation region UV-radiation-sensitive off-color material contact to absorb the suncream of smearing and loses efficacy, and transformation region is shielded.

Introduce the using method of present embodiment product below:

1. whether desirable: suncream is applied in suncream detects use indicator transformation region if detecting the suncream sun-proof result, observe suncream in the sun and detect the indicator transformation region variable color situation of using: if indicator transformation region nondiscolouring or light discolouration are used in the suncream detection, show that suncream effectively stops the absorption UV sunlight, the sun-proof result ideal; Use the obvious variable color of indicator transformation region if suncream detects, show that suncream can not effectively stop the absorption UV sunlight, sun-proof result is undesirable.

2. the suncream of which kind of spf value is used in indication: the suncream of different spf values is applied in suncream detection use indicator transformation region, observe suncream in the sun and detect the indicator transformation region variable color situation of using: if indicator transformation region nondiscolouring or light discolouration are used in the suncream detection, the suncream that shows this spf value effectively stops the absorption UV sunlight, can use; Use the obvious variable color of indicator transformation region if suncream detects, show that the suncream of this spf value can not effectively stop the absorption UV sunlight, cannot use.

3. indication is used suncream under assorted petty situation: be not all to use suncream in any case, the use meeting of suncream has harmful effect to skin, and more weak UV sunlight does not only need protection simultaneously, and is good for one's health.Therefore, have only when UV sunlight more intensely, suncream detect to use indicator transformation region variable color degree of depth under solar ulatraviolet radiation to reach or exceeds suncream and detects when using the indicator warning color, just needs the use suncream.

4. how long indication uses suncream one time:

When smearing suncream on one's body, suncream is applied in suncream detects use indicator transformation region.Because suncream stops the absorption UV sunlight,, suncream uses indicator transformation region nondiscolouring or light discolouration so detecting.Passage in time when the suncream detection uses the indicator transformation region to begin obvious variable color, shows that suncream detects the suncream that uses the indicator transformation region and smeared on one's body and begins inefficacy, and should smear suncream this moment once more.
