Description

[Technical field]

[0001] The present invention relates to a scalp cosmetic application cap, a scalp cosmetic application container, and a method for applying scalp cosmetics using the same, and in particular to a scalp cosmetic application cap that can easily apply the scalp cosmetic to the entire scalp, takes a short application process time, and is less likely to cause uneven application, a scalp cosmetic application container equipped with the cap, and a method for applying scalp cosmetics using the same. [Background technology]

[0002] Conventionally, hair bleaching and coloring have been performed at beauty salons and hair salons. In this bleaching and coloring, chemicals may adhere to the scalp, causing itching and pain. In addition, there is also the problem that the scalp may become discolored by the coloring.

[0003] In order to avoid such problems, a scalp protectant is used before bleaching or coloring (see, for example, Patent Document 1).

[0004] There are several known methods for applying such protective agents, including a method in which the protective agent is filled into a container having a single nozzle, and is then ejected from the tip of the nozzle of the container to apply the agent to the scalp.

[0005] More specifically, the most commonly used method for this purpose is to part the hair using a comb or the like to create a part and expose the scalp, then apply the protective agent to this parting (the exposed scalp area) from the nozzle of the above-mentioned container containing the protective agent, and then create a new part slightly away from the part where the protective agent was applied, and apply the protective agent to this new parting in sequence (sometimes called "blocking") (see, for example, Patent Documents 2 and 3).

[0006] However, as described in Patent Document 3, blocking requires the practitioner to have a high level of skill. In other words, for example, if adjacent partings (one parting and the parting following that one) are too far apart, uneven application of the protective agent may occur. Also, if adjacent partings are too close to each other, uneven application can be prevented, but it will result in more partings than necessary, which is time-consuming and laborious.

[0007] Therefore, as described in Patent Document 3, for example, it has been proposed to eject the agent to be applied (e.g., a cosmetic such as a scalp protection agent) in foam form to avoid the blocking operation, which requires advanced skill. [Prior art documents] [Patent documents]

[0008] [Patent Document 1] JP 2006-056848 A [Patent Document 2] JP 2018-102724 A [Patent Document 3] JP 2013-189382 A Summary of the Invention [Problem to be solved by the invention]

[0009] However, to make the agent to be applied into a foam as in Patent Document 3, it is necessary to use a foaming container that turns the liquid agent in the container into a foam, but this foaming container has a complex structure and is time-consuming to manufacture. Furthermore, if the purpose is to apply the agent to the scalp, if it is in a foam form, there is a risk that it will not be applied sufficiently. Therefore, there has been a demand for a container (especially a cap for this container) that can apply a liquid agent, can easily apply the agent to the entire scalp, and can reduce the occurrence of uneven application, and a cap therefor.

[0010] The present invention has been made in consideration of the problems associated with such conventional technology, and an object of the present invention is to provide a scalp cosmetic application cap that has a nozzle of a simple structure equipped with an ejection path for ejecting a scalp cosmetic such as a liquid scalp protectant, and that can be easily applied to the entire scalp, with a short application process time and little chance of uneven application, a scalp cosmetic application container equipped with this cap, and a method of applying scalp cosmetics using the same.

[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) Cap for applying scalp cosmetics: One embodiment of the scalp cosmetic application cap of the present invention is a scalp cosmetic application cap 100 shown in Figures 1 to 3. This scalp cosmetic application cap 100 includes a cap base 20 for connecting with a container body 150 (see Figure 6) filled with scalp cosmetics, and a nozzle 10 that protrudes from a top surface 21 of the cap base 20, has a discharge path 11 (Figure 3) through which the scalp cosmetics pass, and has a discharge port 13 formed at the tip. The scalp cosmetic application cap 100 is formed with a plurality of nozzles 10, which are arranged in a row, the nozzle pitch P, which is the distance between adjacent nozzles 10, 10, is 3.0 to 15.0 mmmm, and the diameter of the discharge port 13 of the nozzle 10 (inner diameter of the nozzle) is 1.0 to 6.0 mm.

[0024] Such a scalp cosmetic application cap 100 has a nozzle 10 of a simple structure equipped with an ejection path 11 (see FIG. 3) for ejecting scalp cosmetics, making it easy to apply the cosmetics to the entire scalp, with a short application process time and reduced chance of uneven application.

[0025] There is no particular limitation on the material of the scalp cosmetic application cap 100, and any conventionally known material may be appropriately selected. Examples of the material include synthetic resins such as polypropylene, polyethylene, nylon, ABS resin, AS resin, and PET resin.

[0026] (1-1) Cap stand: The cap base 20 is for connection to a container body 150 (see FIG. 6) filled with a scalp cosmetic. A plurality of nozzles 10 protrude from a top surface 21 of the cap base 20.

[0027] The cap base 20 may have a spiral structure 25 on the inside thereof for connecting with the container body 150 (see FIG. 6). The cap base 20 may be rotated to remove it from the container body 150, and the container body 150 may be filled with a scalp cosmetic. In this specification, the term "scalp cosmetic" refers to a cosmetic applied to the scalp, and may be, for example, a scalp protection agent used when bleaching or coloring hair. Examples of the scalp cosmetic include liquid and thixotropic gel-like scalp cosmetic. In other words, a thixotropic gel-like scalp cosmetic does not have fluidity in a stationary state in the container body 150, but when vibration is applied to the scalp, it exhibits fluidity and is discharged in liquid form from the nozzle tip. In this way, the scalp cosmetic application cap of the present invention is a scalp cosmetic application cap that discharges a liquid (i.e., not foamy or solid) scalp cosmetic.

[0028] The size of the cap base 20 is not particularly limited, and may be made to match the size of the container body 150, for example.

[0029] (1-2)Nozzle: The nozzle 10 protrudes from a top surface 21 of a cap base 20, has a discharge passage 11 through which the scalp cosmetic passes, and has a discharge outlet 13 formed at the tip thereof.

[0030] The scalp cosmetic application cap of the present invention is formed with a plurality of nozzles 10, and the scalp cosmetic application cap 100 is formed with three nozzles as shown in Fig. 1. The number of nozzles 10 is not particularly limited, but may be 2 to 5. With such a number, the application process time is further shortened and uneven application is further prevented.

[0031] The length L of the nozzle 10 (see FIG. 3) is not particularly limited and can be set appropriately, but can be 5 to 60 mm, preferably 10 to 40 mm, and more preferably 25 to 35 mm. If it is in such a range, it can be applied to the entire scalp more easily. If the length L of the nozzle 10 is in the above range, ease of use (feel of use) during actual use is improved.

[0032] The scalp cosmetic application cap 100 has a plurality of nozzles 10 arranged in a line as shown in Fig. 1. Such an arrangement shortens the application process time.

[0033] The nozzle pitch P (see FIG. 3), which is the distance between adjacent nozzles 10, is 3.0 to 15.0 mm, can be 3.0 to 10.0 mm, and is preferably 4.0 to 10.0 mm. In this range, the product can be easily applied to the entire scalp, the application process time is short, and uneven application is unlikely to occur. In particular, when the nozzle pitch P is 4.0 to 10.0 mm, production efficiency is further improved. Specifically, if the nozzle pitch P is too short, the nozzle 10 may be damaged when the cap 100 is removed. If the nozzle pitch P is too large, the nozzle 10 tends to be disposed closer to the outer edge 23 of the cap base 20, which may make it difficult to remove the cap 100. Note that if the nozzle pitch P is large (close to the upper limit), uneven application tends to occur more easily.

[0034] The diameter of the nozzle 10 (inner diameter N of the nozzle 10) is 1.0 to 6.0 mm, can be 1.0 to 5.0 mm, preferably 1.5 to 3.5 mm, and more preferably 1.5 to 2.5 mm. It can be easily applied to the entire scalp, the application process time is short, and uneven application is less likely to occur. If the diameter of the nozzle 10 is 1.0 to 5.0 mm, ease of use (feel of use) during actual use is improved.

[0035] Here, in this specification, "arranged in a row" is not limited to the case where the central axes O of the nozzles 10 are located on a straight line (center line T) as shown in FIG. 4, but also includes the concept of the case where the central axes O of the nozzles 10 are arranged to be located within a predetermined band-shaped region as shown in FIG. 5. When the top surface 21 of the cap is viewed along the central axis S of the cap (see FIGS. 4 and 5), a center line T that is a straight line intersecting the central axis S of the cap is drawn, and a first boundary line B1 that is parallel to the center line T and located on one side of the center line T and a second boundary line B2 that is symmetrical with respect to the center line T are drawn, and the band-shaped region is the region between the first boundary line B1 and the second boundary line B2 (see FIG. 5). The distance between the first boundary line B1 and the second boundary line B2 is 3 cm. In other words, the distance between the center line T and the first boundary line B1 or the second boundary line B2 is 1.5 cm. Each nozzle 10 can be arranged in a narrower band-like region, in which case the distance between the first boundary line B1 and the second boundary line B2 can be 2 cm (in other words, the distance between the center line T and the first boundary line B1 or the second boundary line B2 can be 1.0 cm), or even 1.5 cm (in other words, the distance between the center line T and the first boundary line B1 or the second boundary line B2 can be 0.75 cm). This improves ease of use (feel) when actually used.

[0036] Adjacent nozzles 10 in the nozzle pitch P are adjacent to each other in terms of the intersection points K when a perpendicular line A is drawn from the central axis O of each nozzle to the central line T. The nozzle pitch P refers to the distance between the intersection points K. The same applies to the distance between the outlets 13 of adjacent nozzles 10, 10; in other words, it can also be said to be the distance between the outlets 13 after moving parallel to the central axis O on the central line T.

[0037] In the scalp cosmetic application cap 100, the nozzles 10 (e.g., three nozzles 10) arranged in a row, the nozzles 10 located at both ends (the outermost nozzles) may be spaced apart from the outer edge 23 (see FIG. 3) of the cap base 20. By arranging the nozzles 10 apart in this manner, the amount of scalp cosmetic ejected from the multiple nozzles 10 can be made the same.

[0038] The degree of separation from the outer edge 23 of the cap base 20 is not particularly limited, but for example, the separation distance R (see FIG. 2) can be about 1 to 3 mm. In this range, the amount of scalp cosmetics discharged from each nozzle 10 becomes particularly constant. Specifically, the nozzle 10 can be arranged without being separated from the outer edge 23 (see FIG. 3) of the cap base 20, but in this case, the amount of scalp cosmetics discharged from the nozzle 10 that is not separated from the outer edge 23 (see FIG. 3) of the cap base 20 tends to decrease. In other words, the scalp cosmetics are discharged through the discharge path 11, but in the nozzle 10 that is not separated from the outer edge 23 (see FIG. 3) of the cap base 20, this discharge path 11 overlaps with the wall thickness of the container body 150 (see FIG. 6), and tends to be narrowed by the wall thickness. Therefore, the narrowing tends to decrease the amount of discharge from the discharge path 11. By ensuring the above-mentioned separation distance, the opening area of ​​the discharge passage 11 can be made uniform, and the amount of scalp cosmetic discharged from each nozzle 10 can be made constant.

[0039] It is preferable that the diameter of the discharge port 13 of the nozzle 10 (inner diameter N of the nozzle 10) and the distance H between the discharge ports 13 of adjacent nozzles 10, 10 (length of the non-discharge portion) satisfy the following formula. By satisfying this relationship, coating unevenness is further prevented from occurring. Note that, when there are multiple distances H between the discharge ports 13 of adjacent nozzles 10, 10 (length of the non-discharge portion), at least the smallest part satisfies the following formula. Formula: Distance H between the outlets 13 of adjacent nozzles 10 / diameter of the outlets 13 of the nozzles 10 = 0.1 to 8.0

[0040] The distance H between the discharge ports 13 of the adjacent nozzles 10 / the diameter of the discharge port 13 of the nozzle 10 is preferably 0.2 to 7.0, and more preferably 1.0 to 5.0.

[0041] The nozzle 10 may be a rod-like shape that protrudes and extends from the top surface 21 of the cap base 20, and may be tapered toward the tip, or may be a rod-like shape with the same thickness from the base to the tip. When the nozzle 10 is tapered, the defective rate decreases and manufacturability improves. There is no particular limit to the taper angle, but it may be, for example, about 0.5 to 4.0°, and preferably 1 to 3.3°. The taper angle is the angle between the central axis O of the nozzle 10 and the nozzle surface in a cross section (FIG. 3) in the direction in which the nozzle 10 extends.

[0042] The nozzle 10 may come into contact with the scalp at its tip, so the tip may be curved. If the tip is curved in this way, it is possible to prevent the scalp from being damaged when the protective agent is applied.

[0043] (2) Manufacturing method of a scalp cosmetic application cap: As an embodiment of the method for producing the cap for applying a scalp cosmetic material of the present invention, a conventionally known method can be appropriately adopted. Specifically, there can be mentioned a method such as injection molding using a mold or cutting.

[0044] In the cap for applying a scalp cosmetic material of the present invention, if the nozzle has a tapered shape that becomes thinner toward the tip, the cap can be easily released from the mold and the production efficiency of the cap can be improved.

[0045] (3) Container for applying scalp cosmetics: One embodiment of the scalp cosmetic application container of the present invention is a scalp cosmetic application container 200 shown in Fig. 6. This scalp cosmetic application container 200 includes a container body 150 for filling the scalp cosmetic, and the scalp cosmetic application cap 100 connected to the container body 150.

[0046] The scalp cosmetic application container 200 includes the scalp cosmetic application cap 100 as described above, and has a nozzle 10 of a simple structure equipped with a discharge path for discharging the scalp cosmetic, so that the scalp cosmetic can be easily applied to the entire scalp, the application process time is short, and uneven application is unlikely to occur. The scalp cosmetic application container of the present invention is a scalp cosmetic application container that discharges a liquid (i.e., not a foam or solid) scalp cosmetic.

[0047] (3-1) Container body: The container body 150 is a liquid container that is filled with a scalp cosmetic. The container body 150 is not particularly limited as long as it can be filled with and contain a scalp cosmetic, and a conventionally known container can be used. The material of the container body 150 may be the same as that of the scalp cosmetic application cap 100, or may be a different material.

[0048] (3-2) Cap for applying scalp cosmetics: The scalp cosmetic application cap 100 is connected to the container body 150, and is the same as the scalp cosmetic application cap 100 described above. By using this scalp cosmetic application cap 100, the scalp cosmetic can be easily applied to the entire scalp, the application process time is short, and uneven application is less likely to occur.

[0049] (4) How to use the scalp cosmetic application container (How to apply scalp cosmetic): The method for applying a scalp cosmetic of the present invention is a method for applying the scalp cosmetic to the scalp using a scalp cosmetic application container of the present invention filled with the scalp cosmetic. According to this method, by using the scalp cosmetic application container of the present invention, the scalp cosmetic can be easily applied to the entire scalp, the application process time is short, and uneven application is unlikely to occur.

[0050] Here, the scalp cosmetic application container of the present invention can be used in hairdressing and beauty shops, salons, and the like, when applying a scalp protection agent to protect the scalp before bleaching or coloring.

[0051] Conventionally, when applying scalp cosmetics, a task called blocking, in which hair is divided, is performed, but when the scalp cosmetic application container of the present invention is used, this blocking is not necessary. Specifically, the scalp cosmetic application container of the present invention is inserted into the hair, the nozzle tip of the container is brought close to (or in contact with) the scalp, and the protective agent is discharged while moving in a certain direction like a comb, thereby applying the protective agent to the scalp.

[0052] By performing this action over the entire head, the protective agent can be easily and evenly applied over the entire scalp without blocking, even if the user does not have advanced skills. EXAMPLES

[0053] The present invention will be described in detail below with reference to examples, but the present invention is not limited to these examples.

[0054] (Examples 1 to 18, Comparative Examples 1 to 6) A polypropylene (PP) cap for applying scalp cosmetics was produced as shown in Figure 1. The specific nozzle inner diameter, etc. are as shown in Table 1.

[0055] [Table 1]

[0056] In Table 1, "nozzle pitch" means the distance between the central axes of adjacent nozzles. "Nozzle inner diameter" means the diameter of the nozzle outlet. "Non-ejection portion / nozzle inner diameter" means the ratio of the length of the non-ejection portion to the nozzle inner diameter. However, the non-ejection portion is the portion between the opening edge of one nozzle and the opening edge of another nozzle adjacent to that nozzle. In other words, the length of the non-ejection portion is the length between the outlets of adjacent nozzles, and is the portion where the protective agent is not ejected. And, the length of the non-ejection portion specifically means the distance between the opening edge of one nozzle and the opening edge of another nozzle adjacent to that nozzle. "Nozzle position (cm)" indicates the positional relationship of the central axes of each nozzle when the cap is viewed along the central axis direction of the cap. "0 cm" means that the central axis of each nozzle is on a straight line (center line T) that intersects with the central axis of the cap. For example, "0.75 cm" means the length of perpendicular line A when drawn from the central axis O of the nozzle to the center line T, as shown in Figure 5, for the nozzle 10 whose central axis O is the furthest from the center line T.

[0057] In "nozzle taper," "yes" means that each nozzle has a tapered shape that becomes thinner toward the tip, and "no" means that each nozzle is not tapered, but is rod-shaped with the same thickness from the base to the tip.

[0058] In addition, in each of the produced caps, when the nozzle pitch can be measured multiple times, all of them have the same value (common numerical value). For example, in the cap of Example 1, the nozzle pitch can be measured at two places, and both nozzle pitches are 3.0 mm. This is also true when the nozzle inner diameter, nozzle length, and non-ejection part / nozzle inner diameter can be measured multiple times in each of the produced caps. In other words, for example, in a cap having three nozzles, the inner diameters of the three nozzles of the cap are the same, the lengths of the three nozzles of the cap are also the same, and the two "non-ejection part / nozzle inner diameters" of the cap are also the same.

[0059] Next, the prepared scalp cosmetic application cap was connected to a polypropylene container body (volume: 200 ml), and the application time, application unevenness, manufacturability, and usability were evaluated.

[0060] The container body was filled with Savonies Scalp Guard (viscosity 4.0-10.0 Pa·s), a scalp cosmetic product manufactured by Metasecosmetics Co., Ltd., and the evaluation was carried out.

[0061] (Application time) The application time was evaluated based on the time required to apply the scalp cosmetic to the scalp. Specifically, the scalp cosmetic was actually applied to the head (scalp) of five subjects (adults) and evaluated. The evaluation criteria were as follows: if the cosmetic was applied to the entire scalp within 1 minute, it was rated as "A", if it was applied to the entire scalp within 1 minute but within 1 minute and 30 seconds, it was rated as "B", if it was applied to the entire scalp within 1 minute but within 5 minutes but within 1 minute and 30 seconds, it was rated as "C", and if it was applied to the entire scalp in more than 5 minutes, it was rated as "D".

[0062] In Comparative Example 6, a conventional container having one nozzle was used, and a blocking operation was performed in the conventional manner to apply the protective agent to the scalp.

[0063] (Uneven paint finish) The uneven application was evaluated as to whether the protective agent could be applied to the entire scalp when the scalp cosmetic was applied to the scalp. In this test, confirmation was performed in a model experiment using a clear file. Specifically, a polypropylene clear file was placed on a flat surface, and the scalp cosmetic was applied in one direction over the entire surface of a rectangular area (application test area) measuring 20 cm in length and 10 cm in width on the clear file, so that the application areas did not overlap (in a 25°C atmosphere), and the state after 5 seconds was visually observed and evaluated. The evaluation criteria were as follows: "A" indicates that the liquid (scalp cosmetic) was evenly applied and spread over the entire application test area; "B" indicates that there was a small gap in part of the application test area where the liquid (scalp cosmetic) was not applied; "C" indicates that there was a gap in the application test area; and "D" indicates that the application area to which the scalp cosmetic was applied was only a part of the application test area.

[0064] (Manufacturability) Manufacturability was evaluated based on the defective rate when actually molding caps for applying scalp cosmetics. The evaluation criteria were as follows: "A" if the defective rate was 0.1% or less, "B" if it was more than 0.1% and less than 0.5%, "C" if it was more than 0.5% and less than 1.0%, and "D" if it was difficult to manufacture or the defective rate was more than 1.0%.

[0065] (Feeling of use) For usability, five hairdressers applied the protective agent to the subjects' scalps using a scalp cosmetic application container, and rated the ease of use when using the container. The evaluation criteria were as follows: if four or more hairdressers answered that it was easy to use, it was given an "A", if three hairdressers answered that it was easy to use, it was given a "B", if two hairdressers answered that it was easy to use, it was given a "C", and if one or zero out of the five hairdressers answered that it was easy to use, it was given a "D".

[0066] As can be seen from the above Examples 1 to 18 and Comparative Examples 1 to 6, the scalp cosmetic application cap of the present invention has a nozzle with a simple structure equipped with an ejection path for ejecting the scalp cosmetic, and by using this cap, it is possible to easily apply the scalp cosmetic to the entire scalp, the application process time is short, and uneven application is unlikely to occur. Furthermore, it can be seen that this cap improves production efficiency (manufacturability) and improves usability by satisfying further specified conditions. [Industrial Applicability]
