Description

In the present invention, for example, a liquid application material stored inside, for example, a cosmetic device such as an eyeliner or eyebrow, or a partial gray hair dyeing device such as head hair or eyebrows is infiltrated into the application part, and this is applied or drawn from the tip application part. The present invention relates to an applicator used.

  Conventionally, a liquid coating material is stored inside an eyeliner and the like, and this liquid coating material is absorbed and infiltrated into a coating member composed of a core material made of a fiber member or the like, and is applied or drawn by a tip coating portion of the coating member. An applicator to do is generally known.

  About these applicators, in order to adjust the amount of liquid coating material stored inside, an absorbent body that covers the core material is usually provided, and the absorbent material is delivered to the core material. The amount of liquid coating material was adjusted.

Conventionally, as shown in FIG. 4, the absorber 7 is generally made of a resin molded product having an outer peripheral surface formed into a bellows-like irregular surface, and its design requires many adjustments. High mold costs were required.
Moreover, the area | region of the storage part 12 which stores a liquid coating material inside is also decided, and it was not the structure which can change this area | region (refer FIG. 4).

  By the way, the liquid coating material 6 has many different viscosities and materials depending on the usage, and the storage amount of the liquid coating material 6 stored in the storage unit 12 varies.

  Therefore, as described above, the applicator and the internal absorbent body 7 having the same shape and the same size are used, including cases where the liquid applicators 6 exist in a plurality of types and the storage amounts are different. It was considered difficult.

  That is, separately producing the absorbent body 7 made of a resin molded product having a changed length or the like requires expensive mold costs, and the size of the applicator itself is required to change the storage amount. This is because there is a problem that it must be changed.

  By the way, the viscosity of the bulk varies depending on the type of the bulk liquid, and it is extremely expensive to change the shape of the applicator according to the bulk liquid having different viscosities so as not to cause liquid leakage. It was not acceptable.

Accordingly, there has been a demand for an applicator configured so that the applicator of the same standard can be used even when the bulk has different viscosities and each does not leak.

Thus, the applicator according to the present invention has been devised to solve the above-described conventional problems, and there are a plurality of types of liquid coating materials to be stored inside, that is, bulk liquids having different viscosities and materials. And even if the storage amount of the liquid coating material to be stored in the storage part is variously different, even if it can correspond to this multiple types of bulk liquid, and the viscosity of the bulk liquid is different, It is an object of the present invention to provide an applicator configured such that an applicator of the same standard can be used and no liquid leakage occurs.

In the case of the applicator according to the present invention, there are a plurality of types of liquid application materials that are stored in the interior, and the viscosity and material of the liquid application materials are different, and the storage amount of the liquid application material stored in the storage section is also different. Even so, it is possible to use this type of liquid coating material, and even if the bulk liquid has different viscosities, it is possible to use the same standard applicator and prevent the liquid from leaking. There is an excellent effect that can be done.

It is explanatory drawing explaining the structure of the applicator by this invention. It is explanatory drawing explaining the structure of the applicator by another Example. It is explanatory drawing explaining the structure of a plug. It is explanatory drawing explaining the structure of the conventional applicator. It is explanatory drawing explaining the structure of the conventional absorber. It is explanatory drawing explaining the shaking test result after liquid filling.

  Hereinafter, the present invention will be described based on embodiments shown in the drawings.

  FIG. 1 is an explanatory diagram illustrating the configuration of an applicator 1 according to the present invention. The applicator 1 according to the present invention has a body 2 having a substantially cylindrical shape. Moreover, the cap 3 and the inner cap 4 are provided.

  A coating member 5 having a core shape is held in the body 2. The application member 5 is usually composed of a fiber member, and is configured so that a liquid application material 6 described later can be gradually impregnated by a capillary phenomenon or the like.

  The code | symbol 7 shows an absorber. As can be understood from FIG. 1, the absorber 7 is formed in a columnar shape without any irregular shape on the outer peripheral surface, and a through hole 8 penetrating in the axial direction is provided at the center in the axial direction. It has been.

  The application member 5 is inserted through the through hole 8 and attached thereto. Conventionally, as shown in FIG. 4 and FIG. 5, the absorber 7 has been made of a resin molded product whose outer periphery is configured as an uneven surface having a bellows shape. There is a problem that the cost of the applicator itself is increased when the different absorbers 7 having a plurality of types are produced because the cost is high.

  Thus, the absorbent body 7 of the present invention is composed of a flexible member having an impregnation force such as a foam material having open cells inside, and the shape is changed by simply cutting the size and length. It is possible.

  Reference numeral 9 denotes a nose piece, which is fixed to the distal end portion of the body 2 while holding the distal end side of the coating member 5 having the core shape. A drawing member 10 is fitted and attached to the distal end side of the coating member 5, and is configured to draw or apply using the liquid coating material 6 impregnated with the drawing member 10.

  Next, reference numeral 11 denotes a plug, which penetrates and holds the rear end side of the application member 5 in the body 2 and exposes the rear end portion to the storage portion 12 formed next. As understood from FIG. 3, the plug 11 holds the application member 5 by penetrating the inside of the insertion hole 16 on the rear end side of the application member 5 as described above. The shape of the insertion hole 16 is a different shape such as a square shape or a hexagonal shape. This adjusts the width | variety of the clearance gap between the penetration hole 16 and the application member 5 which penetrates this according to the viscosity and material of the liquid application material 6, and the liquid application material 6 infiltrating into the absorber 7 side. I tried to adjust the amount. Here, the liquid coating material 6 is stored in the storage portion 12.

  Reference numeral 13 denotes a stopper for forming the storage part 12. Therefore, the stopcock 13 can be attached to any location in the longitudinal direction of the body 2, so that the area of the reservoir 12 can be easily changed.

  Reference numeral 14 denotes a ball. After the liquid coating material 6 is stored in the storage section 12, the ball 14 is placed in the storage section 12, so that the impregnation of the liquid coating material 6 into the coating member 5 can be promoted. The liquid coating material 6 can be used without waste. There is also a type of applicator 1 that does not have a ball 14.

  Next, the assembly of the applicator 1 will be described. First, the drawing member 10 is attached to the front end side through the nose piece 9 in the body 2, and the absorber cut to a desired length on the rear end side. 7 and the core-shaped application member 5 to which the plug 11 is attached are attached. Thereafter, the liquid coating material 6 is filled into the storage area 12 as a desired area space from the rear end opening 15 of the body 2, and the liquid coating material 6 is stored in the storage section 12 by being covered with a stopper 13. . Thereafter, the rear end of the body 2 is covered with the tail plug 17 to complete the assembly.

  The viscosity of the liquid coating material 6 varies depending on the type of the liquid coating material 6. Therefore, in the case of the liquid coating material 6 having a small viscosity, liquid leakage occurs from the drawing member 10 side attached to the tip of the coating member 5. It sometimes happened.

  However, in the past, in order to prevent this liquid leakage, the applicator was configured by changing the length of the absorber 7 or by changing the size of the storage portion 12, but that alone ultimately The liquid leakage could not be solved.

  So, in this invention, even if it is an applicator incorporating the absorber 7 of the same magnitude | size (length) and the storage part 12 designed in the same magnitude | size, it is liquid leak according to each type of bulk viscosity. The invention is such that the applicator 1 that does not occur can be constituted by the one type of applicator 1. That is, the compression member 20 that compresses the absorbent body 7 accommodated in the body 2 of the applicator 1 and changes the size (length) of the absorbent body 7 is provided in the body 2.

  Here, as described above, the absorbent body 7 is formed of a foam material having open cells therein. And this absorber 7 has the through-hole 8 which the coating member 5 penetrates to an axial direction so that it may be understood from a figure.

  As shown in FIG. 1, if the compression member 20 is interposed on one side of the absorber 7, the absorber 7 is compressed in the longitudinal direction by the length of the interposed compression member 20. Become. That is, when the absorbent body 7 has a length of 20 mm, if the compression member 20 having a length of 4 mm is interposed, the absorbent body 7 is compressed to a length of 16 mm and contracts.

  When the absorbent body 7 is compressed, the absorbent body 7 formed of a foam material having open cells in the inside thereof has improved adhesion with the coating member 5 inserted into the through hole 8 and penetrates into the coating member 5 side. The applied liquid coating material 6 is sucked up by capillary action. Therefore, the excess liquid coating material 6 is not impregnated on the side of the coating member 5 or the drawing member 10, and as a result, liquid leakage of the liquid coating material 6 can be prevented.

  FIG. 6 shows the experimental results. In FIG. 6, three applicators 1 having the same configuration are prepared as Sample 1, Sample 2, and Sample 3, and each has no compression member 20, the compression member 20 has a length of 4 mm, and the compression member 20. A swing inspection test after filling the liquid coating material 6 having a length of 5.5 mm was performed. The swing inspection is an inspection in which the applicator 1 is held and the applicator 1 is shaken several times in the vertical direction. Thus, it was inspected how many times the liquid leaked when shaken.

  Here, the viscosity of the liquid coating material 6 was 6.0 CP (centipoise).

  Then, as shown in FIG. 6, the sample without the compression member 20 leaked when sample 1 and sample 2 were shaken 6 times, and sample 3 was leaked when shaken 5 times. In addition, when the compression member 20 of 4 mm is provided in the body 2 and the absorber 7 is compressed, the sample 1 leaks when it is shaken 8 times, and the sample 2 leaks when it is shaken 7 times. Sample 3 leaked when shaken 9 times.

  Furthermore, when the absorbent member 7 is compressed by providing a compression member 20 having a length of 5.5 mm, the sample 1 leaks when it is shaken 12 times, and the sample 2 leaks when it is shaken 11 times. In Sample 3, liquid leakage occurred when shaken 13 times.

  Next, the liquid coating material 6 was tested again by changing the viscosity to 5.0 CP (centipoise).

  Then, in the case where the compression member 20 was not provided, the sample 1, sample 2, and sample 3 leaked when they were shaken four times. Further, when the absorbent member 7 is compressed by providing a compression member 20 having a length of 4 mm, the sample 1 leaks liquid when shaken 6 times, and the sample 2 leaks liquid when shaken 7 times. In No. 3, liquid leakage occurred when shaken 6 times.

  Furthermore, when the absorbent member 7 is compressed by providing a compression member 20 having a length of 5.5 mm, liquid leakage occurs when the sample 1 and the sample 2 are shaken 9 times, and when the sample 3 is shaken 10 times, the liquid is leaked. A leak occurred.

Thus, when the compression member 20 is used and the absorbent body 7 is compressed in the longitudinal direction to improve the adhesion to the coating member 5, the excess liquid coating material 6 does not penetrate into the coating member 5 side, and the absorbent body. 7 absorbs excess liquid coating material 6.
Therefore, as a result, it has been found that the applicator 1 of the present invention does not cause liquid leakage.
