BACKGROUND OF THE INVENTION
The present invention relates to a patch testing tool that anyone can easily perform patch testing.
[0002]
[Prior art]
In general, in the practical application of drugs, cosmetics, detergents, etc. that are applied directly to the skin, in order to investigate whether these have an adverse effect on the skin, the test object is brought into contact with the skin for 24 to 48 hours on the skin. A patch test is being conducted to check the antigen-antibody reaction that occurs in
[0003]
An example of a tool for performing the patch test is a patch test tape as shown in FIG. This is composed of a pressure-sensitive adhesive sheet 1 having a pressure-sensitive adhesive applied to the entire surface of one side, a plurality of circular pads 2 attached on the pressure-sensitive adhesive surface at predetermined intervals, and a release paper 3 covering the surface of the pressure-sensitive adhesive surface. Yes. When performing a patch test, first, the release paper 3 is peeled off to expose the circular pad 2, and a plurality of types of test objects to be tested (the same type of drugs etc. with different concentrations, Alternatively, a plurality of types of drugs and the like are applied to each circular pad 2. Next, each circular pad 2 is peeled off from the pressure-sensitive adhesive sheet 1, the test object application surface is placed on the skin of the monitor and arranged, and the pressure-sensitive adhesive sheet 1 is pasted thereon to fix each circular pad 2. Then, after leaving for 24 hours to 48 hours, the adhesive sheet 1 and the circular pad 2 are peeled off, and the state of the part in contact with the test object is observed, whereby the antigen / antibody reaction of the test object to the skin is observed. I try to inspect.
[0004]
[Problems to be solved by the invention]
Thus, the conventional patch test tool has a configuration in which a plurality of circular pads 2 are held side by side on the adhesive sheet 1 so that a manufacturer or a specialized research institution can efficiently perform a patch test. Only commercial use is available.
[0005]
However, even if the product has been put on the market after the safety of the skin has been confirmed by the patch test recently, it may cause some irritation when used by customers with sensitive skin. . Also, even if people are not particularly aware that their skin is particularly sensitive, they may be affected by the intake of artificial chemical substances in their diet and the influence of environmental hormones through water and air. Using the product may cause allergies.
[0006]
Therefore, when recommending new cosmetics to customers, some cosmetic dealers apply a small amount of a sample of the product to the customer's skin and, for example, provide a service that diagnoses whether the skin is not affected the next day. There are also places to go.
[0007]
However, as already mentioned, there are only patch testing tools for business use.Even if each customer wants to perform a patch test easily at home, there is no suitable tool. Is simply applying the sample directly to the customer's skin at the store. In this case, the main component to be inspected may volatilize immediately and the influence on the skin may not be confirmed, and an accurate reaction result cannot be obtained.
[0008]
The present invention has been made in view of such circumstances, and an object of the present invention is to provide a completely new type of patch testing tool that anyone can easily perform a patch test.
[0009]
[Means for Solving the Problems]
In order to achieve the above object, the present invention is a patch test tool distributed to a user for performing a patch test prior to use of a product used in contact with the skin, which is stamped and formed. A patch in which an adhesive layer is formed on one side, and an adhesive sheet whose surface is covered with release paper is hermetically packaged in a state of being combined by the number used for a single patch test. The test tool is the first gist, and among them, in particular, the test object holding pad is punched from a urethane foam sheet having a thickness of 1.0 to 3.0 mm into a circle having a diameter of 10 to 20 mm. The second gist is a tool for patch testing.
[0010]
In addition, among the above, the present invention is particularly special in that the pressure-sensitive adhesive sheet has a substantially lower half of a large-diameter upward arc shape, and the substantially upper half gently connects two downward small-diameter arcs arranged side by side. The third gist is a patch test tool set in a flat plan view shape.
[0011]
DETAILED DESCRIPTION OF THE INVENTION
Next, an embodiment of the present invention will be described.
[0012]
FIG. 1 shows an embodiment of a patch test tool according to the present invention. This patch test tool is prepared by a cosmetic manufacturer for a patch test of a new product lotion, and is distributed to customers along with the sample of the lotion at the store or by direct mail. The patch test tool has a configuration in which a test object holding pad 10 and an adhesive sheet 11 for fixing the pad 10 to the skin surface are combined and sealed and packaged one by one. For the packaging, the pad 10 and the adhesive sheet 11 are overlapped on a base 12 made of cardboard cardboard, and the transparent plastic film 13 is further stacked thereon, and the surroundings (area shown by hatching in the figure) are heat-sealed. It is done by sealing.
[0013]
In addition, on the upper part of the mount 12, the name “free time”, which is a name given by the cosmetic manufacturer to the patch test tool, is displayed. In addition, a semicircular extending portion 13a that is not heat-sealed is provided at the upper right portion of the transparent plastic film 13 to be joined to the base portion 12 by heat sealing, and the extending portion 13a is pulled forward. Thus, as shown by the chain line, the pad 10 and the adhesive sheet 11 which are the contents can be taken out.
[0014]
As shown in FIG. 2 (a), the test object holding pad 10 is a disc having a diameter L = 16 mm and a thickness of 1.5 mm, and a urethane foam sheet having a thickness of 1.5 mm is punched into a circle. It is obtained. Fine continuous pores are formed in the pad 10, and when the test object is applied or dropped onto the pad 10, the test object is not repelled and is stably held.
[0015]
In addition, as shown in FIG. 2B, the adhesive sheet 11 used for fixing the pad 10 has a substantially lower half of a large-diameter upward arc (curvature radius R ₁ = about 33 mm) and a substantially upper half of the upper half. A special planar view shape is formed by gently connecting two downward small-diameter circular arcs (curvature radius R ₂ = about 12 mm) arranged on the left and right.
[0016]
And the said adhesive sheet 11 is comprised with the base material 15 which consists of a nonwoven fabric, the adhesive layer 16 formed in the single side | surface, and the release paper 17 which coat | covers the surface of the said adhesive layer 16, as shown in FIG. ing.
[0017]
When performing a patch test using the above-described patch test tool, first, a lotion to be tested is dropped onto the pad 10 and held on the surface of the pad 10, and the holding surface is applied to the skin. Then, the release paper 17 (see FIG. 3) of the pressure-sensitive adhesive sheet 11 is peeled off to expose the pressure-sensitive adhesive layer 16, and the pressure-sensitive adhesive layer 16 is directed toward the skin so as to cover the pad 10 and the surrounding skin. Thereby, the pad 10 is fixed. In this state, after leaving for 24 to 48 hours, the adhesive sheet 11 and the pad 10 are peeled off, and the state of the part where the pad 10 is in contact is observed, so that the effect of the antigen / antibody reaction on the skin of the skin lotion is affected. I can know.
[0018]
Therefore, a customer who distributes the above-mentioned patch test tool together with a new product lotion sample can take it home and perform the patch test by himself / herself when he / she likes it. If there is no particular effect on the skin and the purchase of the lotion is desired, the lotion is purchased at a cosmetic store.
[0019]
In this way, according to the above-mentioned patch test tool, it is possible to perform a patch test using the sample before actually purchasing the product (skin lotion), so whether or not the product fits your skin. You can purchase after confirming. Therefore, after purchase, the product can be purchased and used in peace without causing an uneconomical situation such as rough skin or the like that cannot be used. In addition, for cosmetic manufacturers, it is possible to make the customer aware that there may be cases where it does not match depending on the customer's constitution, and to recommend an optimal product, so that more counseling can be provided to the customer.
[0020]
Note that the patch test tool is not necessarily distributed with the sample. For example, a large number of the patch test tools are placed in a box or the like in the vicinity of a tester displayed at the store, and the usage method thereof. It is possible to allow customers who come to the store to freely perform patch tests using a tester. Then, when peeling off, the customer may come to the store again, and the cosmetics salesperson may peel off and confirm the test result, and then consult the product purchase. Of course, in the face-to-face counseling, the counselor attaches the pad 10 to the customer's skin using the above-mentioned patch test tool, visits the store again the next day or the next day, sees the result, and performs further counseling. Also good.
[0021]
The patch test tool does not need to be sealed using the mount 12 and the transparent plastic film 13 as in the above example, and can be used to package the pad 10 and the adhesive sheet 11 in a sanitary manner. Any packaging form is acceptable.
[0022]
Further, the shapes and dimensions of the pad 10 and the pressure-sensitive adhesive sheet 11 are not limited to the above example, and can be set as appropriate. However, it is preferable that the pad 10 is circular because it is easy to handle. Moreover, if the adhesive sheet 11 is also made into a special shape as in the above example, it is preferable that the adhesive sheet 11 is easily peeled off by placing a finger on one of the two bulged portions.
[0023]
And when the said pad 10 is circular, it is suitable on handling that the diameter L is set to 10-20 mm. On the other hand, the size of the adhesive sheet 11 is not particularly limited as long as it has an area sufficient to cover the pad 10 and the surrounding skin.
[0024]
Moreover, the material of the said pad 10 and the adhesive sheet 11 is not restricted to said example, The various material conventionally used as a tool for patch tests can be used. For example, as a material of the pad 10, in addition to urethane foam, flannel, felt, and the like can be given.
[0025]
Note that the adhesive sheet 11 does not need to have a structure (see FIG. 3) in which the surface of the adhesive layer 16 is covered with the release paper 17 as in the above example. The pressure-sensitive adhesive layer 16 of the pressure-sensitive adhesive sheet 11 may be attached to the surface, and the pressure-sensitive adhesive sheet 11 may be peeled off from the mount 12 when the pressure-sensitive adhesive sheet 11 is used. In this case, the mount 12 functions as the release paper 17.
[0026]
Furthermore, in the above example, the pad 10 and the adhesive sheet 11 are combined and packaged one by one. For example, when two kinds of lotions are used in combination, the effect is high. It is preferable to prepare a patch test tool including two pads 10 and one adhesive sheet 11 as a set so that a patch test can be simultaneously performed on two types of lotion samples. . Thus, the number of the pads 10 and the adhesive sheet 11 to be combined is not particularly limited, and can be appropriately combined depending on the contents of the patch test.
[0027]
The patch test tool of the present invention is not limited to cosmetic patch tests, and can be used for patch tests of various products such as various chemicals, detergents, bathing agents, and the like applied to the skin.
[0028]
