An appropriate amount of coating solution can be delivered to the coated body 10. The application liquid can be applied by applying the application body 10 to a desired site.
In these embodiments, the pipe 63 is not necessarily required depending on the viscosity of the coating liquid and the hardness of the coated body.

[Applied body 10]
The coated body 10 is formed of an elastic resin material such as rubber, elastomer or closed cell body so as to obtain the necessary coating performance, and the members other than the coated body 10 have a density and rigidity that can provide the necessary airtight performance and support performance. And is made of a resin material or a metal material.

  The application body 10 has a flat tapered shape with tip portions protruding from the front end of the front shaft 61 and exposed by double-sided (upper surface, lower surface) taper portions 21 and 22. A discharge port 24 a of the communication path 24 is opened in the upper tapered portion 21. The application portion 10 a of the application body 10 is provided so as to protrude further from the discharge port 24 a of the communication path 24 to the tip.

  In the present invention, the entire application body 10 may be an elastic body, or only the application part 10a may be formed of an elastic body. The application portion 10a is made of an elastic material, and an elastic material such as rubber or elastomer can be raised. Moreover, as long as the material of the application part 10a is liquid-tight, for example, if it is an elastic body which does not have continuous foaming, it can be used without any problem.

For example,
(1) Examples of the rubber include NBR, silicon rubber, EPDM, fluorosilicon rubber, fluorine rubber, urethane rubber, natural rubber, chlorobrene rubber, butadiene rubber, and butyl rubber.
(2) Examples of the elastomer include a styrene elastomer, a vinyl chloride elastomer, an olefin elastomer, a polyester elastomer, a polyamide elastomer, and a urethane elastomer.
(3) Examples of the closed cell body include polyethylene foam, polyvinyl chloride foam, and polystyrene foam.

  As shown in detail in FIG. 2, in the application body 10, the application portion 10 a is a portion extending further forward from the opening position of the discharge port 24 a and is formed as a flat portion 25. The communication path 24 extends straight from the front shaft 3 in the axial direction, bends in the shape of a "<" in the vicinity of the upper surface tapered portion 21 and is exposed in the vicinity of the upper surface tapered portion 21, and the discharge port 24a is opened.

[Usability and application performance when the vertical repulsion force of the coated body is set]
FIG. 3 is an explanatory view for setting the repulsive force of the application body 10, FIG. 4 is a measurement explanatory view of the repulsive force of Comparative Examples 1-2 and Examples 1-9 in which the material of the application body 10 is various, and FIG. Example of measurement results of use feeling and coating unevenness of Comparative Examples 1 and 2 and Examples 1 to 8, FIG. 6 illustrates a method for evaluating coating unevenness, FIG. 7 illustrates an evaluation standard for coating unevenness, and FIG. FIG. 9 is an explanatory diagram for evaluating coating unevenness.

  In the application body 10 of the embodiment, the application portion 10a has a vertical repulsion force of 0.01 to 1.40 (N) at a portion 3 mm from the tip.

  The repulsive force of the coating portion 10a was detected by a force gauge 40 as shown in FIG. The force gauge 40 is moved backward by the strength of the force applied to the detection end 40a with the saucer and detects the force (a numerical value (N) is displayed on the display unit 40b).

  Specifically, as shown in FIGS. 4 to 5, each of the resin products (Q100F to an elastomer prototype material) was used as a material to form each coated body as Comparative Examples 1-2 and Examples 1-9. .

  About these comparative examples 1-2 and Examples 1-9, as shown in FIG. 3, the part of 3 (mm) from the front-end | tip of the application part is set to the detection end part 40a in the horizontal direction (the advancing / retreating direction of the detection end part 40a). In this state, the force (N) that the detection end portion 40a receives from the coating portion was measured as a state of contact in a slidable manner from the vertical direction.

In each example, the material (shape) is also changed to create an application body.
Comparative Example 1: Soft polypropylene (Soft PP: trade name Catalloy, grade name Q100F, manufactured by Sun Allomer Co., Ltd.)
Comparative Example 2: Data 5 (thermoplastic resin product)
Example 1: Data 4 (thermoplastic resin product)
Example 2: Soft polypropylene (soft PP: trade name Newcon, grade name NNT2005, manufactured by Nippon Polypro Co., Ltd.)
Example 3: Data 3 (thermoplastic resin product)
Example 4: Data 2 (thermoplastic resin product)
Example 5: Thermoplastic polyurethane (one type of elastomer resin: trade name PANDEX, grade name T-8375, manufactured by DCI Bayer Polymer Co., Ltd.)
Example 6 A spatula shape was formed using the same material as in Example 5.
Example 7: Data 1 (thermoplastic resin product)
Example 8: Silicone material having a hardness of 50 degrees (comp)
Example 9: Elastomer prototype material

  The data 1 to data 5 are inventors of thermoplastic resin products so that the elastic force located between the resin products used in each example can be obtained in terms of the data of the force (N) received from the application part. Are adjusted to create a coated body.

  The results of measuring the elastic force of the tip portion of the application body to be actually applied are shown in FIGS.

  In addition, in each of these coated bodies, the feeling of use when actually applied and the evaluation value for occurrence of uneven coating were evaluated. The evaluation results are shown in FIG.

  In the evaluation of the feeling of use, the tester applied the bulk to each case of the coated body to evaluate the feeling of use. The usability evaluation in FIG. 5 is “◎”: good, “◯”: somewhat good, “△”: normal, “black △”: somewhat hard and difficult to use, “×”: hard and difficult to use. is there.

Regarding the evaluation of occurrence of coating unevenness at each viscosity, the bulk of the coating liquid is generally 10,000 (mPa · s) as a general viscosity for makeup cosmetics (at a shear rate of 5 (sec ⁻¹ )). A test was conducted. The viscosity range was 1/10 of 1,000 (mPa · s) and 10 times that of 100,000 (mPa · s).

  Further, as shown in FIG. 6, the coating unevenness evaluation test is performed by dropping the bulk 44 on the non-absorbing surface 42 having a thickness of 3 (mm) and moving the application body along the non-absorbing surface at a constant speed. The bulk was spread by the application body 10.

  The state of the spread bulk 44 was observed, and five grades of “◎”, “◯”, “Δ”, “black Δ”, and “×” were evaluated. As shown in FIG. 7, this evaluation standard is evaluated as “◎”: good (a state in which the coating liquid is uniformly applied and spread on the coated surface), and evaluation “×”: defective (a coating liquid on the coated surface is applied). It was scraped off by the body and could not be spread at all). The evaluations “◯” to “black Δ” are intermediate between them, and were evaluated according to the degree.

  The applied body was moved at an early speed (150 mm / sec) and a slower speed (50 mm / sec).

  As shown in FIG. 5, the evaluation results were that in Comparative Examples 1 and 2, the feeling of use was hard, the coating unevenness at each viscosity was bad, and any evaluation was bad.

  On the other hand, in Example 1, the feeling of use was slightly hard and the coating unevenness was slightly non-uniform, but there was no blur.

  In Examples 2 to 9, the feeling of use is normal to good, and uneven coating does not occur at all, which does not occur at all. Accordingly, in the present invention, the application portion has a vertical repulsion force of 0.01 to 1.4 (N) at a portion 3 (mm) from the tip, thereby providing good usability and little coating unevenness. It can be a body.

  In particular, Examples 4 to 9 are particularly preferable because the feeling in use is good and there is no coating unevenness regardless of the viscosity of the coating solution, and the coating properties are good.

  Therefore, if the application portion of the application body has a vertical repulsion force of 0.01 to 0.70 (N) at a portion 3 mm from the tip, the application is more usable and less uneven coating is applied. It can be a body. In particular, when the coating solution has a viscosity range of 1,000 (mPa · s) to 100,000 (mPa · s), there is no coating unevenness and the coated body has good coating properties.

[Application performance by setting the dimensions of the application part of the application body]
As shown in FIG. 8, the application portion 10a of the application body 10 of the embodiment has a distance L from the discharge port 24a to the tip within the dimension range of 1 ≦ L ≦ 20 (mm), and from the discharge port 24a. It is assumed that the width W of the portion up to the tip is in the dimension range of 2 ≦ W ≦ 20 (mm). The evaluation in this case is shown in FIG.

  When the relationship between the width W and the length L of the coating portion 10a exceeded the above range, it was difficult to apply, and when the relationship was within the range, the coating property was good.

  In addition, it is desirable that the width W and the length L of the application portion 10a are appropriately selected in accordance with the application target within the above range.

[Make the material of the coated body transparent or translucent]
In the embodiment, as shown in FIG. 2, the application body 10 is made of a transparent or translucent material so that the application liquid in the communication path can be visually observed. It is more preferable to make the color different from that of the coating solution to make it translucent.

  By doing so, the color of the coating liquid supplied to the coating body can be seen through the transparent or translucent coating body even if the coating liquid tank inside the main body is not visible. In addition, it is possible to visually confirm how the coating liquid comes out, and it is possible to prevent the coating liquid from being excessively discharged at the start of use.

  Next, a modification of the embodiment will be described.

  The application body 10 of the liquid applicator in the above embodiment can be variously modified as shown in FIGS. 1 to 2 as well as Modifications 1 to 8 shown in FIGS. In addition, the whole structure of a liquid applicator is the same as that of embodiment of FIGS. 1-2, and attaches | subjects the same code | symbol to the same part.

  The application body 10A according to Modification 1 of FIG. 10 has no step on the upper taper portion 21 and is integrally formed flat from the rear of the discharge port 24a to the flat portion 25. The discharge port 24a is always open.

  In the application body 10B according to the modified example 2 of FIG. 11, a step is formed on the upper taper portion 21 via a shoulder 23, and a discharge port 24a is opened in the shoulder 23 due to the step.

  The shoulder 23 has a larger inclination angle than the upper surface tapered portion 21 and faces forward.

  The communication path 24 extends straight forward in the axial direction of the application body 10, and narrows in a slit shape near the discharge port 24a. The slit-like portion is normally narrow or tightly closed, and forms a valve mechanism that opens when the discharge pressure of the coating liquid 4 increases. Since the application part 10a is partitioned by the shoulder 23, the application liquid that has come out of the slit valve mechanism concentrates on the application part 10a, is difficult to escape, and can be applied without waste.

  The application body 10C according to the modified example 3 of FIG. 12 has no step on the upper surface taper portion 21, but the upper surface taper portion 21 and the lower surface taper portion 22 become thinner as if the rear side close to the front shaft 3 has been removed. In front, it is integrally formed flat from the rear of the discharge port 24a to the flat surface portion 25. The discharge port 24a is always open.

  The application body 10D according to the modified example 4 of FIG. 13 has no step on the upper surface taper portion 21 and is integrally formed flat from the rear of the discharge port 24a to the flat surface portion 25, but the lower surface taper portion 22 opens downward. The applicator body 10 generally has a downward warping shape from the rear to the front in a side view. The discharge port 24a is always open.

  In the application body 10D according to the modification example 4, the application liquid 4 discharged from the discharge port 24a stays in the upper side taper portion 21 and retains more application liquid than the application body of the modification example 3 including the rear side. It is easy to apply, and it is easy to make it adhere in a wide range from the base end to the tip end of the application body at the time of application to the target site, and can be spread widely. Further, the elasticity of the entire application body 10D can be softened by setting the lower surface tapered portion 22 in an arc shape.

  FIGS. 14A to 14D are applied bodies 10 </ b> E to 10 </ b> H according to modified examples 5 to 8, and are examples in which the discharge port 24 a that opens to the upper surface tapered portion 21 is variously changed.

In FIG. 14A, the application body 10E of the modified example 5 shown in FIG. In addition, in the application body 10F of the modified example 6 shown in FIG. Moreover, the application body 10G of the modified example 7 shown in (c) has a rectangular discharge port 24a. Further, the application body 10H of the modified example 8 shown in (d) has a slit formed in the discharge port 24a, and is opened by pressurization by the elastic force of the application body 10G, and is closed when there is no pressure or the pressure is reduced. It is possible to prevent extraneous matters such as external dust and germs from being mixed in the communication path 24 and the coating liquid 4 in the coating liquid storage space 2b.
In these embodiments, the communication passage 24 is bent in the shape of a “<” in the upper surface taper portion 21 in the vicinity of the upper surface taper portion 21, but the communication passage 24 extends straight in the axial direction to form the discharge port 24 a. Is also possible.
