Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a coating device for applying a coating material such as a correction fluid, a paint, a paint, an ink, a paste, a liquid cosmetic, a powder cosmetic, and a medicine.

[0002]

2. Description of the Related Art Brushes and brushes are examples of applicators. The brush has a brush ear in which a plurality of brushes are gathered at a base as an application destination. The brush has an application destination where a plurality of application pieces in which a plurality of hairs are bundled are arranged. Some of these brushes, such as toothbrushes, exclusively use the tip of the application piece, but many are used for surface coating using the side of the application piece.

[0003]

A brush for surface coating is more convenient for applying a certain width than a brush. However, the stability of the application width is never good because the width of the entire application destination is widened by the application of force.

[0004]

The gist of the present invention is to provide an application destination of an applicator in which a plurality of applicators made of flat and elongated elastic plates are arranged in a staggered manner with a gap therebetween.

[0005]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An example will be described with reference to FIGS. The container body 1 is made of, for example, a blow molded article made of a synthetic resin which can be deformed by pressing.
The application member 5 is sandwiched between the tip body 4 screwed to the member. The application destination member 5 includes three comb-shaped members 6 as an application unit,
It has two coating material discharge holes 7 formed between the comb-like members 6, and a connecting hole 8 between the coating material discharge holes 7 and the coating material storage chamber 2. Each comb tooth-shaped member 6 does not face each comb tooth 9. That is, the adjacent comb-tooth members 6 have their own comb teeth 9 positioned in the gap between the opposing comb teeth 9, and the comb teeth 9 are staggered as a whole,
These are also arranged with a gap therebetween.

Each of the comb teeth 9 is flat and elongated, and its flatness matches the flatness of the comb tooth-shaped member 6. The material of the coating destination member 5 is selected so that the comb teeth 9 can be elastically deformed. Examples of materials include natural rubber or styrene-butadiene rubber, polyisoprene,
Diene-based synthetic rubbers such as butadiene rubber, chloroprene rubber, and nitrile rubber; non-diene-based synthetic rubbers such as butyl rubber, ethylene propylene rubber, urethane rubber, chlorosulfonated polyethylene, acrylic rubber, and fluororubber; chlorinated polyethylene; epichlorohydrin And synthetic rubbers such as polysulfide rubber, thermoplastic elastomers such as styrene, olefin, ester, urethane, 1,2-polybutadiene and polyamide, and soft synthetic resins such as nylon and polyethylene.

[0007] These materials may be appropriately selected depending on the kind of the coating material, the use of the coating tool, the desired coating touch and the like. For example, in the case of general glue obtained by dissolving polyvinyl alcohol in water, silicon rubber, olefin-based thermoplastic elastomer, polyester-based thermoplastic elastomer, etc. are selected in consideration of deterioration. In the case of using an organic solvent, select in consideration of solvent resistance, for example, select fluororubber for methylcyclohexane, etc.Otherwise, if a relatively smooth coating touch is to be obtained, friction resistance For example, select one with less number. By the way, in the case of an applicator to be used by holding it with a normal hand, it is generally good to select an applicator having a Shore hardness of about A30 to D80 irrespective of the type of the glue, the handwriting corrector, or the like.

[0008] The comb teeth 9 are the "coated pieces made of a flat and slender elastic plate" in this embodiment. That is, this example is an example in which the application pieces are integrated in each row, and each row is also integrated with each other. Each coated piece is independent and can be fixed to the body of the applied member by using, for example, insert molding, bonding, press-fitting, etc. Because it is easier to prepare.

The arrangement of the comb teeth 9, that is, the shape of the whole application destination is appropriate. Further, it is not necessary that all the comb teeth 9 (therefore, the applied pieces) have the same shape. FIG. 4 shows an example of the deformed state of the comb teeth 9 at the time of use. It has become. When the coating is performed in the direction of the arrow in the drawing, first, a sufficient amount of the coating agent is supplied to the coating surface, and thereafter, an example is performed in order to uniformize the coating. In some cases, it is required that the comb teeth 9 located in the portion be closer to the outer comb teeth 9 than the inner comb teeth 9). The following are some examples.

In FIG. 5, the number of comb teeth 9 located at the center is one more than that on both sides. If the width of the comb teeth 9 and the gap between the comb teeth 9 are all equal, the comb tooth-shaped members 6 have different widths. If the number of comb teeth 9 located at the center is one less than that on both sides as in the example described above, the reverse is also possible.

In FIG. 6, the comb teeth 9 are arranged in a trapezoidal shape as a whole. The application width differs between the application on the right side of the drawing and the application on the left side.

In FIG. 7, the central part of the comb-like member 6 is concave. The coating agent is applied in a relatively large amount at the concave central portion.

FIG. 8 shows the comb teeth 9 of the comb-like member 6.
Are different from each other in height.

FIG. 9 shows the comb teeth 9 of the comb-like member 6.
Are different from each other in thickness.

FIG. 10 shows a single comb tooth-shaped member 6.
In which the heights of the bases of the comb teeth 9 are different.

In FIG. 11, the protruding tip positions of the comb teeth 9 of the comb-like member 6 are also different.

FIGS. 12 to 14 show a case in which a frame portion 10 is provided. Needless to say, the comb teeth 9 have a shape as a coating piece.

FIG. 15 shows another example of the shape of the frame portion 10.

16 and 17, the base of the comb teeth 9 at both ends of the central comb-shaped member 6 is formed thicker than the other bases, and the thickness of the comb teeth 9 is tapered so that the tip becomes thinner. are doing.

In FIGS. 18 and 19, tapered ribs are provided on the outer sides of the comb teeth 9 on both sides so that the tips become lower.

In FIGS. 20 to 22, the protrusions are provided on the outer bases of the comb teeth 9 on both sides.

In FIGS. 23 to 25, the comb teeth 9 on both sides are formed into truncated pyramid shapes.

Although not shown, various other operations can be performed. For example, in all of the above, the comb-shaped members 6 are arranged in three rows.
As described above, the application pieces may be appropriately arranged within a range in which the application pieces are arranged in a staggered manner. Here, when such a complicated shape is to be obtained by injection molding, if there is a possibility that removal from the mold becomes difficult,
A shape using an undercut as shown in FIG. 26 can also be used. In addition, the number and shape of the coating material discharge holes and the arrangement location thereof are appropriate. For example, each of the two coating material discharge holes 7 in the above-described one is divided into two to make a total of four coating material discharge holes. Can also. A comb-like member 6
May be located in the gap between the comb teeth 9 in the inside. Further, the container main body 1 may have an application agent discharging structure using a piston-cylinder mechanism or an appropriate valve mechanism. Further, instead of using such an application tool with a built-in application agent, it is also possible to use a so-called writing brush type.

[0024]

According to the application destination of the applicator of the present invention, in which a plurality of coating pieces made of a flat and elongated elastic plate are arranged in a staggered manner with a gap therebetween, the coating pieces are formed in the thickness direction. Since it is easily deformed but not easily deformed in the width direction, it is possible to smoothly apply with a stable application width.
