Description

The present invention relates to a collector-type applicator containing a low viscosity cosmetic liquid, and more particularly to an eyeliner that emphasizes a stylish appearance.

  Conventionally, collector-type applicators are a well-known technology, but thin-type applicators are preferred because importance is placed on portability and design due to the diversity of the market.

  Although the collector-type applicator can obtain a stable outflow from start to use as compared with the applicator using the cotton in the ink tank, the collector needs to maintain the amount of ink and air replacement. Because it needs a certain size, it was unsuitable as a slender applicator.

  In addition, the fine axis collector type applicator has problems of direct current leakage and blowout. Also, with large collectors, the application rate is significantly reduced and the distance that can be applied is shortened.

  Therefore, there has been proposed a collector-type applicator that solves the problem of the application liquid leakage while using a thin-shaft applicator with a thin outer diameter (see JP-A-2015-2984).

JP, 2015-2984, A

  However, even with the collector-type applicator of Patent Document 1, the internal pressure in the ink tank changes due to the opening and closing of the cap. Therefore, if the cap is repeatedly opened and closed, the liquid in the ink tank is pulled into the collector, and eventually the amount of ink stored in the collector increases, which may eventually cause the liquid leakage.

  Then, this invention makes it a subject to provide the collector type applicator which can prevent a coating liquid leak, even if it opens and closes a cap.

According to the present invention, there is provided an application body, a shaft provided with the application body on the front side, a cap covering the application body in a detachable manner on the front end of the shaft, and a collector mounted on the shaft body and having a comb-like outer peripheral surface. A storage section for storing the coating liquid in the storage space at the rear of the shaft, and a derivative for guiding the coating liquid in the storage section to the coating body, and temporarily supplying the coating liquid to the coating body to the collector In collector-type applicators to be stored in
A gap between the inner circumference of the shaft and the outer circumference of the collector is 0.05 mm or less.

  In the present invention, the collector has a pipe-like portion for accommodating the induction core therein and circulating the coating liquid and a sheet-like body around the pipe-like portion, and the pipe-like portion has an inner circumference and an outer circumference. It is preferable that the wall has no hole penetrating therethrough.

  In the present invention, a tip shaft for supporting the application body is mounted on the tip portion of the shaft body, the collector is mounted on the tip portion, and a storage portion is formed on the rear portion. It is preferable that the coating liquid be accommodated in the direct solution in the accommodation space.

  In the present invention, it is preferable that the outer peripheral surface of the rear part of the collector and the inner surface of the front shaft be in fluid tight contact.

  In the present invention, the coating liquid in the housing space is guided to the coating body via the core inserted into the pipe-like portion in the collector, and the core protrudes from the rear end of the collector into the housing space. Preferably not.

  According to the applicator of the present invention, in the collector-type applicator, the air displacement passage is formed by setting the gap between the inner periphery of the shaft body to be the air displacement passage (air displacement hole) and the outer periphery of the collector to 0.05 mm or less. The gap is narrow and the meniscus is intensified, so that even if the coating liquid from the storage section flows into the air replacement path, the liquid film is easily formed in the narrow gap. As a result, the meniscus is strong in the narrow gap even if the coating liquid is drawn into the collector by pumping in a state where the internal pressure change in the storage section occurs (the internal pressure rises, etc.) repeatedly when opening and closing the cap. The coating liquid is trapped in the gap to form a liquid film, and the coating liquid can be prevented from further flowing into the collector. It can be made insusceptible to the pumping effect of the cap opening and closing, and the coating liquid leakage can be prevented even if the collector type cap is opened and closed.

  In the present invention, the collector has a pipe-like portion for accommodating the induction core therein and circulating the coating liquid, and the pipe-like portion is formed with a hole penetrating between the inner periphery and the outer periphery By setting the wall not to be transmitted, pressure change to the air replacement passage is not transmitted by the pipe-like portion having no hole even when opening and closing the cap, so that it is possible to prevent the internal pressure change of the accommodating portion through the inner induction core. Therefore, it becomes insusceptible to the pumping of the cap opening and closing, and no liquid leakage occurs. Thereby, commercialization is possible without using a cap as a spring type inner cap.

The content of the carbon black is preferably 1 to 20% by mass, and more preferably 5 to 15% by mass, with respect to the total amount of the liquid cosmetic. When the content of this carbon black is less than 1% by mass, coloring is thin and it becomes insufficient as a cosmetic. On the other hand, when it exceeds 20% by mass, the viscosity becomes too high. The liquid cosmetic applicator is not preferable because the liquid can not be discharged smoothly.

The dispersant is made of a film-forming resin, and improves the dispersibility of the carbon black as a coloring material, and also functions as a resin for film formation.
The dispersant which can be used is not particularly limited as long as it has the above-mentioned function, and, for example, acrylic acid, methacrylic acid or their alkyl esters or derivatives, vinyl acetate, vinyl pyrrolidone, one or two of them Copolymers selected from those selected from the above species and betaine-type alkyl acid-based amphoteric resins may, for example, be mentioned.

The content of these surfactants is preferably 0.5% by mass or less, more preferably 0 to 0.3% by mass, with respect to the total amount of the liquid cosmetic.
If the content of the surfactant is more than 0.5% by weight, the water resistance is poor and a sufficient fixing power can not be obtained, which is not preferable.

The liquid cosmetic composition of the present invention uses water (including purified water, distilled water, ion exchanged water, pure water, ultrapure water, etc.) as a solvent. The water content is the balance containing the above-described components and optional components described later.
Furthermore, the liquid cosmetic composition of the present invention may contain, in addition to the above-mentioned essential components and the like, optional components and the like used for ordinary liquid cosmetic compositions.

It is a non-perforated wall-like thing in which the hole which penetrates a wall over circumference and perimeter is not formed.

  The coating liquid in the housing space is guided to the coating body 18 through the core inserted into the pipe-like portion in the collector 16, and the core protrudes from the rear end of the collector 16 into the housing space 14a. Not.

  In the collector-type applicator according to the embodiment, the outer peripheral surface of the rear portion of the collector 16 is in fluid-tight contact with the tip inner wall surface. Specifically, as shown in an enlarged manner in FIG. 3, the collector 16 includes the outer periphery of the sheet at the rear of the temporary storage portion 16 c and the inner periphery of the shaft 14, and the inside of the specific shaft body 12. A gap δ between the circumference and the outer periphery of the rear temporary storage portion 16c is 0.05 (mm) or less.

  The outer periphery of the support wall 28 at the rear end of the rear side temporary storage portion 16 c of the collector 16 is fixed by being fitted into the recess 14 e of the inner surface of the shaft main body 12.

  In the collector 16, from the front side temporary storage portion 16 b to the rear side temporary storage portion 16 c, the ink longitudinal groove (slit) 26 for guiding the coating liquid into the fin gap is exposed at the rear end portion It is formed in the accommodation space 14a of the body 14 so that it can be exposed.

  Further, between the fins of each of the plurality of sheets in the front side temporary storage portion 16b and the rear side temporary storage portion 16c, a thick support wall 28 in contact with the inner surface of the front shaft 10 is appropriately partitioned.

  Here, FIG. 4 is an explanatory view of the collector 160 of the collector-type applicator according to the comparative example. (A) shows a longitudinal cross-sectional view of the collector 160, and (b) shows an enlarged view around the rear of the collector 160 in the application part.

  As shown in FIG. 4, the rear side temporary storage portion 160c of the collector 160 of the comparative example has (a) a gap d of 0.06 (mm) between the inner periphery of the shaft main body 12 and the outer periphery of the rear side temporary storage portion 160c. It is 0.2 (mm) or more.

  Further, in the comparative example, (a) in the pipe-like portion 160e of the collector 160, the hole e penetrating from the hollow portion 160d on the inner periphery to the outer periphery is formed. In the collector 160 of the comparative example, parts other than the above (a) and (a) are the same as those of the embodiment of FIGS. 1 to 3 and are denoted by the same reference numerals.

  The collectors of the embodiment and the comparative example are compared.

  In the air replacement hole (air replacement passage), a gap between the outer peripheral portion of the collector 16 and the shaft member 14 becomes an air replacement hole from the slit 26 of a portion where the collector 16 is fitted to the inner periphery of the shaft member 14. In the collector 16 according to the embodiment, as shown in FIG. 2, the outer diameter of the blade of the rear side temporary storage portion 16 c is expanded to set the clearance δ between the inside of the shaft 14 to 0.05 (mm) or less Is narrow.

  On the other hand, in the comparative example, the gap d is as large as about 0.2 (mm).

  In the collector 16 according to the embodiment, as shown in FIG. 2, the meniscus immediately below the air replacement hole (near the rear end of the collector 16, specifically, the opening of the slit 26 to the accommodation space 14 a) is raised to It is less susceptible to changes in internal pressure due to opening and closing. That is, by setting the gap δ between the outer periphery of the rear side temporary storage portion 16c and the inside of the shaft 14 to 0.05 (mm) or less, the coating liquid adheres to that portion and the liquid film is easily formed. 20 reduces the pumping effect of opening and closing. Since the coating solution can be prevented from blowing out, the inner cap can be made unnecessary.

  On the other hand, in the comparative example, since the gap d is as large as about 0.2 (mm), it is difficult for the coating liquid to adhere and the liquid film to be hardly formed, so that it is difficult to reduce the pumping effect of opening and closing the cap 20.

  Moreover, in the comparative example, since the hole e is formed in the pipe-like portion 160e of the collector 160, when the cap 20 is opened or closed in the accommodation space 14a via the hollow portion 160d from the air replacement hole around the collector through the hole e. There is a possibility of blowout due to pressure fluctuation due to pumping, but in the applicator of the embodiment, there is no influence of pressure fluctuation at the time of pumping because it is the pipe-like portion 16e having no hole e.

What showed the Example and the comparative example in more detail is shown as Table 1 below.
This shows the relationship between the number of times of repeated attachment and detachment of the cap and the gap δ.
As evaluation criteria,
A There is no problem on the appearance B. Infiltration of the coating solution into the collector is observed but there is no problem on the function. C The coating solution leaks from the tip of the application part.

  According to the collector-type applicator according to the above embodiment, the air gap δ between the inner periphery of the shaft 14 to be the air replacement passage (air replacement hole) and the outer periphery of the collector 16 is 0.05 mm or less. The gap in the replacement passage is narrow and the meniscus is intensified, and even if the coating liquid from the storage space 14a flows into the air replacement passage, the liquid film is easily formed in the narrow gap. Thereby, even if the coating liquid is drawn into the collector 16 by pumping in a state where the internal pressure change in the accommodation space 14a occurs (the internal pressure is increased, etc.) repeatedly when opening and closing the cap, the meniscus is Because it is strong, the coating liquid is trapped in the gap δ to form a liquid film, and the coating liquid can be prevented from further flowing into the collector 16. Cap 20 can be made less susceptible to pumping, and even if the collector cap is opened and closed, coating liquid leakage can be prevented.

  In the present invention, the collector 16 has a pipe-like portion 16e which accommodates the inner core 22 of the induction core and circulates the coating liquid, and the pipe-like portion 16e has an inner periphery and an outer periphery. Since the wall is not formed with a hole penetrating all the way through, the pressure change to the air substitution path is not transmitted by the pipe-like portion 16e without holes even when opening and closing the cap 20, so the storage space through the inner core 22 inside The internal pressure change of 14a can be prevented. Therefore, it becomes difficult to be affected by the pumping of the opening and closing of the cap 20, and no liquid leakage occurs. Thereby, commercialization is possible without using a cap as a spring type inner cap.

  According to the embodiment, a collector-type applicator, in particular an eyeliner, having the same performance as that of a conventional thick shaft can be realized even with a thin shaft. In the case of an eyeliner, it has a stylish appearance, and by making it a collector-type, it is possible to draw an eyeline that is thick and clear until the end.

  Further, in the embodiment, as shown in FIG. 2, the outer diameter of the blade of the rear side temporary storage portion 16c is expanded to set the clearance δ of 0.05 (mm) or less with the inside of the shaft body 14 By narrowing the gap on the rear temporary storage portion 16c near the position where the slit 26 opens in the housing portion (housing space), the meniscus δ is strengthened to prevent liquid leakage due to drawing in of the coating liquid. However, the position of the gap may be not only the rear side but also the middle or front side.

The present invention can be used in general applicators, but can be used particularly for eyeliner solutions with low viscosity.
