Description

[Technical field]

[0001] The present invention relates to a hair coloring agent cup, and more particularly to a hair coloring agent cup that can improve the workability of hair coloring when a film body such as a transparent film made of synthetic resin is laid in the cup and a hair coloring agent is poured onto the film body to perform hair coloring work. [Background technology]

[0002] Traditionally, when dyeing hair at barber shops and beauty salons, two types of hair coloring agents (for example, agent 1 and agent 2) are placed in a cup, mixed together, and a chemical reaction occurs. The resulting mixture (mixed hair dye) is then applied to the hair to dye it.

[0003] When applying the hair dye to hair, the mixed hair dye is taken out of the cup with a brush and carefully applied to the hair.

[0004] Over time, the hair coloring agent (mixed hair dye) oxidizes and hardens onto the cup, but washing off this hardened hair coloring agent is extremely time-consuming and places a heavy burden on hairdressers.

[0005] To solve such problems, a hair dye cup has been reported that includes a plate that is a container for holding the hair dye and a support that supports the plate (see, for example, Patent Document 1). However, even when such a plate is used, it still requires time and effort to wash the plate.

[0006] One option is to use a disposable cup after each use, but using a disposable cup is undesirable because it places a burden on the environment.

[0007] Therefore, instead of a plate as described in Patent Document 1, a transparent film (film body) made of synthetic resin is placed inside the cup (on the inner surface), and the hair color agent is mixed and the hair dyeing process is performed. After the hair dyeing process is completed, the film body is removed from the cup and discarded together with the hair color agent adhering to the film body. [Prior art documents] [Patent documents]

[0008] [Patent Document 1] JP 2004-313403 A Summary of the Invention [Problem to be solved by the invention]

[0009] However, when the film body is placed on the cup as described above, the hair coloring agent has viscosity, so that the film body may float up from the cup when stirring the hair coloring agent or scooping up the mixed hair dye to apply to the hair (see Figure 5). When the film body floats up from the cup in this way, the hair coloring agent cannot be mixed sufficiently, and it is difficult to scoop up the appropriate amount with a brush or the like to apply it to the hair, resulting in poor workability when coloring.

[0010] In particular, as mentioned above, since the mixed hair dye solidifies over time, the decrease in workability is a serious problem.

[0011] The present invention has been made in consideration of the problems associated with the prior art, and its object is to provide a cup for hair coloring agent that can improve the workability of hair coloring when a film body, such as a transparent film made of synthetic resin, is placed inside the cup and hair coloring agent is poured onto this film body to perform hair coloring work (mixing the hair coloring agent and taking out an appropriate amount).

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0022] The following describes the embodiments of the present invention. However, the present invention is not limited to the following embodiments. It should be understood that modifications and improvements made to the following embodiments based on the ordinary knowledge of those skilled in the art without departing from the spirit of the present invention are also within the scope of the present invention.

[0023] (1) Hair color cup: The hair color agent cup of the present invention is a hair color agent cup having a film body disposed on the inner surface side and handling a hair color agent on the film body, and has an upper opening and a tensile strength of 9 g / cm on at least a part of the inner surface on which the film body is disposed. 2 The adhesive layer has the above adhesive area.

[0024] This hair color cup can improve the workability of hair coloring when a film body such as a transparent film made of synthetic resin is placed inside the cup and hair coloring work (mixing the hair coloring agent and dispensing the appropriate amount) is performed by pouring the hair coloring agent onto this film body.

[0025] The hair coloring agent cup of the present invention is not particularly limited as long as it has a predetermined adhesive region as described above. For example, the hair coloring agent cup itself may be made of a material having adhesiveness and have the above-mentioned predetermined adhesive region (inner surface adhesive region) on its inner surface, or the hair coloring agent cup may include a cup body constituting the hair coloring agent cup, and a predetermined material may be sprayed or applied to the inner surface of the cup body to form an adhesive film (adhesive layer) having the above-mentioned predetermined adhesive region. Furthermore, an adhesive portion made of a predetermined material may be disposed on the inner surface of the cup body. This adhesive portion may be integrally formed with the cup body.

[0026] Specifically, one embodiment of the hair color agent cup of the present invention is a hair color agent cup 100 shown in Figures 1 to 3. This hair color agent cup 100 is a hair color agent cup in which a film body 50 (see Figure 4) is placed on the inner surface 100a side, and a hair color agent 60 (see Figure 4) is handled on this film body 50. The hair color agent cup 100 has a cup body 10 having an upper opening 11, and a hair color agent 60 (see Figure 4) located on at least a part of the body inner surface 13, which is the inner surface of the cup body 10 on which the film body 50 (see Figure 4) is placed, and has a tensile strength of 9 g / cm 2 and an adhesive portion 20 having the above-mentioned adhesive regions.

[0027] In addition, "handling the hair color agent on the film body" means either stirring the hair color agent supplied onto the film body (stirring and mixing in the case of using multiple hair color agents (e.g., agent 1 and agent 2)) or scooping up appropriate amounts of hair color agent (in a state ready for application to hair) from the film body.

[0028] This type of hair colorant cup 100 can improve the workability of hair coloring when a film body 50 (see Figure 4), such as a transparent film made of synthetic resin, is placed in the cup and hair colorant 60 (see Figure 4) is poured onto this film body 50 to perform hair coloring work (mixing the hair colorant and taking out the appropriate amount).

[0029] The film body 50 may be, for example, a plastic wrap (mostly a transparent film), but may also be made of paper, etc. There is no particular limit to the thickness of the film body 50 as long as it is thin, and it may also be in the form of a sheet.

[0030] Here, if a synthetic resin wrap (film body) is used instead of the plate described in Patent Document 1, the film body can be disposed of after the hair coloring work, and the plate washing and drying work as in Patent Document 1 can be omitted. In addition, by using a paper plate, the plate can be disposed of without washing, etc., but this is more wasteful and puts a greater burden on the environment than a film body. Therefore, by using a film body, it is possible to increase productivity per hour and minimize the burden on the environment at the same time.

[0031] In addition, the film with the remaining hair dye adhering to it after hair coloring is considered combustible waste, but nowadays, incinerators have improved in performance, so there is almost no concern about the generation of dioxins due to this combustible waste. On the other hand, hair dyes may contain chemicals such as paraphenylenediamine that are difficult to biodegrade and contribute to environmental hormones, so washing the remaining hair dye off the plate may contribute to marine pollution.

[0032] (1-1) Cup body: The cup body 10 has an upper opening 11. The upper opening 11 allows the hair color agent to be poured into the cup body 10 through the upper opening 11, and further allows the hair color agent to be stirred and the mixed hair dye agent to be scooped up.

[0033] The cup body 10 has an upper opening 11, and is not particularly limited in size or material as long as it is capable of stirring the hair color agent, and any conventionally known cup body can be appropriately used.

[0034] The material of the cup body 10 may be a resin (such as a synthetic resin) or a metal, and a synthetic resin can be used.

[0035] (1-2)Adhesive part: The adhesive portion 20 is located on at least a part of the main body inner surface 13, which is the inner surface of the cup main body 10 on which the film body 50 (see FIG. 4) is placed. This adhesive portion 20 is an adhesive region in which the portion in contact with the film body 50 has adhesiveness. By having this adhesive portion 20, the film body 50 placed on the inner surface 100a of the hair color agent cup 100 can be adhesively fixed, improving the workability of hair coloring.

[0036] The adhesive portion 20 may be disposed on the entire main body inner surface 13, which is the inner surface of the cup body 10, or may be disposed on a part of the main body inner surface 13. When disposed on a part of the main body inner surface 13, the position and size (area) of the adhesive portion 20 are not particularly limited and can be set appropriately, but it is preferable that the size (area) is 50% or more of the total area of ​​the main body inner surface 13.

[0037] The adhesive portion 20 has an adhesive area of ​​9 g / cm 2With such a predetermined tensile strength, the film body 50 in contact with the adhesive area of ​​the adhesive portion 20 can be adhesively fixed, and the film body 50 can be prevented from floating off the cup during hair coloring work. The adhesive strength (tensile strength) is 12 g / cm 2 It is recommended to use more than 14g / cm 2 It is even better to set it to more than this.

[0038] Furthermore, there is no particular upper limit to the tensile strength of the adhesive region of the adhesive portion 20, but it is preferably 60 g / cm 2 It can be less than 40g / cm 2 It is recommended to use less than 20g / cm 2 It is even better to set it to be equal to or less than the upper limit. By setting it to be equal to or less than the upper limit, sufficient dust resistance can be obtained in the adhesive region of the adhesive part 20. In other words, for example, it is possible to prevent dirt, dust, paper fibers, cut pieces of hair, and the like from adhering to the adhesive region of the adhesive part 20 during storage of the hair color agent cup 100. By preventing the adhesion of dirt, dust, and the like in this way, the adhesiveness is maintained and the effort of cleaning the adhering dirt, etc. can be saved.

[0039] Furthermore, by setting the tensile strength of the adhesive region to be equal to or less than the upper limit, the film body 50 can be easily peeled off when the coloring operation is completed and the film body 50 is peeled off from the hair color agent cup 100. In other words, if the tensile strength of the adhesive region exceeds the upper limit, the force with which the film body 50 is adhesively fixed is too strong, and peeling off the film body 50 is troublesome or the film body 50 may be torn.

[0040] In this specification, "tensile strength" is a value measured as follows. That is, a load was applied in sequence and the state in which the adhesive portion 20 having an adhesive area peeled off was confirmed. Specifically, a test device as shown in FIG. 6 was first prepared. Then, an adhesive portion 20 measuring 4 cm in length and 5 cm in width was prepared as a test specimen, and the above-mentioned film body (resin wrap) measuring 4 cm in length and 5 cm in width was attached so that the adhesive portion 20 (adhesive area) and the film body overlapped each other in a 4 cm square (overlapping area 16 cm2).2 ) to obtain a laminated test sheet 70 (see FIG. 6). Then, as shown in FIG. 6, one end of the adhesive portion 20 of the laminated test sheet 70 is placed on top, and one end of the film body 50 of the laminated test sheet 70 is placed on the bottom, and weights 71 are sequentially placed on the one end sides of the film body 50 to apply weight. Then, the weight is measured when the entire film body 50 has peeled off from the adhesive portion 20 (when the film body 50 has fallen). Then, a plurality of laminated test sheets 70 are prepared and a similar test is performed to measure the weights, and the average value is calculated to obtain the tensile strength.

[0041] The adhesive portion 20 may be in the form of a sheet having a flat surface 21 that contacts the film body 50. This flat surface 21 may be a smooth surface with few irregularities. By having such a flat surface 21, the film body 50 to be attached and fixed may easily stick to the adhesive portion 20, improving convenience.

[0042] The surface roughness of the flat surface 21 (i.e., the arithmetic mean height of the surface irregularities) can be 0.2 μm or less, and preferably 0.0001 to 0.2 μm. If the flat surface satisfies such conditions, the film body 50 to be attached and fixed can be easily attached to the adhesive portion 20, further improving convenience.

[0043] Here, the surface roughness of the plane 21 is the arithmetic mean height of the projections and recesses on the surface of the plane 21 measured with a white light interferometer (manufactured by Zygo Corporation).

[0044] The adhesive portion 20 has adhesiveness (adhesive area) in the portion that contacts the film body 50, and there are no particular limitations on the material, thickness, etc., as long as it can adhesively fix the film body.

[0045] The material of the adhesive portion 20 (the material of the portion in contact with the film body 50) may be, for example, nitrile rubber, elastomer (urethane elastomer, etc.), resin such as silicone, or the like.

[0046] The adhesive portion 20 may be made of a material such as a resin having adhesive properties, and may be used as the adhesive portion as is by utilizing the properties of the resin, or may be a structure having a support portion fixed to the cup body 10 and an adhesive layer formed on this support portion.

[0047] The thickness of the adhesive portion 20 is not particularly limited and can be set appropriately, for example, to about 10 μm to 5 mm.

[0048] (1-3) Outer adhesive part: The hair coloring agent cup of the present invention may further have an outer adhesive region on the edge of the upper opening on the outer surface. This outer adhesive region may be made of a material having adhesiveness for the hair coloring agent cup itself, and the predetermined outer adhesive region may be formed on its outer surface, similar to the adhesive region (inner surface adhesive region) formed on the inner surface of the hair coloring agent cup, or the hair coloring agent cup may have a cup body constituting the hair coloring agent cup, and a predetermined material may be sprayed or applied to a predetermined position on the outer surface of the cup body to form an adhesive film (adhesive layer) having the predetermined outer adhesive region. Furthermore, an adhesive part made of a predetermined material may be arranged at a predetermined position on the outer surface of the cup body. This adhesive part may be integrally formed with the cup body.

[0049] The hair color agent cup 100 in this embodiment may further have an outer adhesive portion 30 at the edge of the upper opening 11 on the main body outer surface 15, which is the outer surface of the cup main body 10. With the outer adhesive portion 30, after the film body 50 is placed on the inner surface 100a of the hair color agent cup 100, the film body 50 protruding from the upper opening 11 of the cup main body 10 can be folded back and fixed to the outer adhesive portion 30 (see FIG. 4). By fixing the protruding film body 50 to the outer adhesive portion 30 in this manner, it is possible to prevent a decrease in workability, for example, due to the film body 50 protruding during hair coloring work covering the upper opening 11 of the cup main body 10 and interfering with the work.

[0050] The outer adhesive portion 30 may be formed continuously along the upper opening 11 as shown in FIG. 2, but may also be discontinuous (for example, formed in a dashed line).

[0051] The edge of the upper opening 11 on which the outer adhesive portion 30 is arranged can be in a range of at least 2 mm away from the upper opening 11 based on the upper opening 11 of the cup body 10, preferably in a range of up to 20 mm away from the upper opening 11, more preferably in a range of up to 15 mm away from the upper opening 11, and particularly preferably in a range of up to 10 mm away from the upper opening 11. Setting the edge of the upper opening 11 in the above range not only prevents a decrease in workability, but also more effectively prevents the film body 50 from peeling off during work.

[0052] The outer adhesive portion 30 may be of the same material and structure as the adhesive portion 20, but may also be of a different material and structure.

[0053] (2) Manufacturing method of hair coloring agent cup: The hair color agent cup of the present invention can be produced, for example, as follows.

[0054] For example, a cup for hair coloring can be made by preparing a cup body made of resin or metal, applying the adhesive material (liquid material) to the inner surface of the cup body by spraying or the like, and then drying it.

[0055] As another method, a predetermined sheet-like adhesive portion may be prepared and this sheet-like adhesive portion may be fixed to the inner surface side of the cup body, that is, the inner surface of the cup body.

[0056] Furthermore, when a resin cup body is used, the resin cup body and the adhesive portion may be integrally molded. As a method for integral molding, a conventionally known method can be appropriately adopted.

[0057] (3) How to use the hair color cup: The hair colorant cup of the present invention is used when performing hair coloring in a barber or beauty salon, etc., and specifically, it can be used as a container for stirring the hair colorant.

[0058] When using this hair color agent cup, the user first prepares a film body (e.g., a plastic wrap) of a predetermined size to be placed on the inner surface side of the hair color agent cup. Then, the film body is placed on the inner surface side of the hair color agent cup, and is brought into contact with the adhesive part of the hair color agent cup and adhesively fixed.

[0059] Then, the hair coloring agent is poured onto the film body. At this time, multiple hair coloring agents (for example, the first agent and the second agent) can be poured together.

[0060] The hair coloring agent poured onto the film body is then stirred, and it is important to stir it thoroughly, because if it is not stirred thoroughly, uneven coloring will occur when it is applied to the hair.

[0061] Here, when using a conventional hair coloring agent cup 200, the hair coloring agent 60 has a certain viscosity, so when the hair coloring agent 60 is stirred, the film body 50 also moves together with the hair coloring agent 60 (see FIG. 5), making it difficult to stir. For example, it takes time to thoroughly mix the first and second agents, and care must be taken to prevent the film body 50 from moving, which is troublesome. On the other hand, by using the hair coloring agent cup of the present invention, it is possible to prevent the film body from floating (separating) from the cup. Therefore, it is possible to reduce the need to pay attention to prevent the film body 50 from moving, the mixing time can be shortened, and furthermore, color unevenness caused by insufficient stirring can be prevented.

[0062] Furthermore, the hair coloring agents are stirred and thoroughly mixed to form a mixed hair dye, and then the mixed hair dye is applied to the hair using a brush or the like. At this time, an appropriate amount is scooped up, but if a conventional hair coloring agent cup is used, the film body rises up along with the scooped mixed hair dye (a mixture of multiple hair coloring agents), making it difficult and time-consuming to scoop up the appropriate amount of mixed hair dye. On the other hand, by using the hair coloring agent cup of the present invention, the film body is unlikely to float (or separate) from the cup when the appropriate amount is scooped up, making it easy to scoop up the appropriate amount.

[0063] When using the hair color agent cup of the present invention, once application of the required amount of mixed hair dye to the hair has been completed, the film body can be peeled off from the hair color agent cup and discarded as is. EXAMPLES

[0064] The present invention will be described in detail below with reference to examples, but the present invention is not limited to these examples.

[0065] (Examples 1 to 16, Comparative Example 1) In Examples 1 to 16 and Comparative Example 1, hair color cups were prepared using the materials shown in Tables 1 and 2, and had an adhesive portion (thickness 5 μm) with an adhesive region on the entire inner surface. The cup body was made of plastic. Furthermore, the prepared hair color cups had an outer adhesive portion with an outer adhesive region on the outer surface of the cup body.

[0066] The tensile strength of the material constituting each adhesive part (tensile strength of the adhesive region) was measured as follows. First, a test apparatus as shown in FIG. 6 was prepared. A material (adhesive part material) measuring 4 cm in length and 5 cm in width was prepared as a test specimen, and the above-mentioned film body (resin wrap) measuring 4 cm in length and 5 cm in width was attached to this material so that they overlapped with each other in a 4 cm square (overlapping area 16 cm2). 2), a laminated test sheet was obtained. Thereafter, in an atmosphere of 24°C and 45% RH, one end of the material of the laminated test sheet was placed on top, and one end of the film body of the laminated test sheet was placed on the bottom, and weight was applied to this film body in sequence. Then, the weight at which this film body was peeled off from the test body, which was the material (i.e., the peeling weight of the film body from the test body (tensile strength (g / cm 2 ))) were measured. The results are shown in Tables 1 and 2. The higher the measured tensile strength, the higher the adhesiveness. After applying a weight, the tape was left for 30 seconds and the presence or absence of peeling was judged.

[0067] The prepared hair color agent cups were evaluated for the following: adhesion (i.e., fixation of the film body), retrievability after use, dust resistance, flatness (surface roughness), and stickiness.

[0068] [Table 1]

[0069] [Table 2]

[0070] In Table 1, "hard rubber" is hard rubber manufactured by Pstyle. In Table 2, "agent A" is the main silicone agent (manufactured by Engraving Japan under the trade name PROSILICONE PLATINUM HTV-2000(A)). "agent B" is the silicone curing agent (manufactured by Engraving Japan under the trade name PROSILICONE PLATINUM HTV-2000(B)). When the blending ratio of agent B to agent A exceeded a certain value, the tensile strength of the resulting silicone changed significantly (the tensile strength decreased).

[0071] (sticky) The adhesiveness of the hair coloring agent cup was evaluated by placing a film body so as to cover the entire inner surface of the prepared hair coloring agent cup. The fixation of the film body was evaluated by this adhesiveness evaluation. In other words, it was examined whether or not a problem such as the film body floating up from the hair coloring agent cup occurs during hair coloring work. The film body used was "Savonese Wrap" manufactured by Kikuboshi Co., Ltd. Note. This film body is generally used in hair salons and beauty salons that perform hair coloring.

[0072] Specifically, the hair coloring agent was poured onto the film of the hair coloring agent cup in which the film was placed, and then the hair coloring agent was stirred 10 times. The state of the film at this time was checked, and the adhesion was evaluated according to the following criteria. A: When the film body does not peel off B: When the film body is displaced C: When peeling of the film body is confirmed D: When the film is not attached to the inner surface of the hair coloring agent cup

[0073] (Recoverability after operation) After the above-mentioned evaluation of adhesion, the ease of peeling the film body from the inner surface of the hair coloring agent cup was checked, and the recoverability of the film body after the hair coloring work was evaluated. The evaluation criteria were as follows. A: The film body can be easily peeled off from the hair color agent cup. C: The film body can be peeled off from the hair color cup, but the peeling requires a great deal of force.

[0074] (dustproof) The hair coloring agent cup thus prepared (i.e., the hair coloring agent cup without the film body) was left for one week under an atmosphere of room temperature (24°C) and humidity of 45% RH. After that, air was blown once onto the inner surface (adhesive area) of the hair coloring agent cup, and the surface of the adhesive part (adhesive area) was visually observed and evaluated according to the following criteria. A: When no dust is found on the surface (adhesive area) of the test specimen (material) that is the adhesive part. B: When dust easily adheres to the surface (adhesive area) of the test specimen (material) C: When dust tends to adhere to the surface (adhesive area) of the test specimen (material) D: When dust easily adheres to the surface (adhesive area) of the test specimen (material) that is the adhesive part, and the dust cannot be removed without washing.

[0075] (Planarity (surface roughness)) The adhesive part having an adhesive area on the surface made of the material shown in Table 2 was prepared and left for one day. Thereafter, in an atmosphere of room temperature (24°C) and humidity 45% RH, a 1 mm long x 1 mm wide portion of the adhesive area of ​​the prepared adhesive part was measured with a white interferometer at three points, and the arithmetic mean height of the unevenness in the portion was calculated. The adhesive part made of the material shown in Table 1 was measured with a white interferometer (manufactured by Zygo Corporation) immediately after opening, and the arithmetic mean height of the unevenness was calculated in the same manner as above. The average value of the three measured points was calculated. After checking, the film was evaluated according to the following criteria. If the evaluation of this "surface roughness" is good (the value of the arithmetic mean height is small), the film body can be well fixed when placed in a hair coloring agent cup. A: When the arithmetic mean height of unevenness in the adhesive area of ​​the surface of the test piece (material) that is the adhesive part is 0.1 μm or less B: When the arithmetic mean height of the unevenness in the adhesive area of ​​the surface of the test piece (material) that is the adhesive part is more than 0.1 μm and less than 0.2 μm C: When the arithmetic mean height of unevenness in the adhesive area of ​​the surface of the test piece (material) that is the adhesive part is more than 0.2 μm and 0.35 μm or less D: When the arithmetic mean height of unevenness in the adhesive area of ​​the surface of the test piece (material) that is the adhesive part is more than 0.35 μm

[0076] (Sticky) At the same time as the evaluation of "flatness", the absence of stickiness was also evaluated. The evaluation was performed according to the following criteria. If the evaluation of this "stickiness" is good, the film body can be fixed more satisfactorily when placed. A: When the surface of the test specimen (material) that is the adhesive part is not sticky B: When the surface of the test piece (material) that is the adhesive part is slightly non-sticky C: When the surface of the adhesive part of the test piece (material) is sticky D: When the surface of the adhesive part of the test piece (material) is sticky

[0077] The results of Examples 1 to 16 and Comparative Example 1 show that a hair color cup using the materials of Examples 1 to 16 as the adhesive portion can improve the workability of hair coloring when a film body such as a transparent film made of synthetic resin is placed inside the cup and hair coloring is performed by pouring the hair color onto this film body, because the film body is less likely to float (separate) from the cup. [Industrial Applicability]

[0078] The hair color agent cup of the present invention can be used as a cup for stirring a hair color agent during hair coloring. [Explanation of symbols]
