[Industrial applications]

 The present invention uses a coating liquid such as a correction liquid having a viscosity of 1 to 300 cps, an ink, a paint, a cosmetic liquid or a mildew preventive repair agent for joints, and is particularly suitable for applying fine linear coating with a valve. Regarding the ingredients.

[0002]

[Prior art]

 Conventionally, the inside is a coating liquid storage chamber, and the apex with a through hole is fixed to the opening of the container body whose one end is an opening, and the opening is made of metal with a seat on the inner surface of the tip. The tubular body is fixed, and the valve portion is abutted against the seat portion in the metallic tubular body to form a valve mechanism, and the valve body whose tip projects outward from the metallic tubular body tip opening is repelled. Therefore, many valve-applied applicators arranged so as to urge them forward have been proposed.

In the above applicator with valve, the valve body is made of metal or resin, and various processing methods such as turning, forging, and injection molding are adopted.

The valved applicator has been proposed especially for the purpose of performing thin linear application (writing). Therefore, the metal tubular body needs to be thin, and the valve body arranged inside is very small.

[0005]

[Problems to be solved by the device]

 This is because the valve applicator has a high defective rate during production and low productivity. In assembling the valved applicator, the parts are generally aligned in one direction by an aligning machine such as a parts feeder machine, and then fed to the assembly machine to be assembled into the valved applicator. However, the valve body is small as described above, and although there are differences in the shape in the front-back direction, the extent is small, and further, the size and weight of the valve body vary and individual valve bodies are placed. Due to factors such as variations in condition, some of them may face in the opposite direction during alignment.

When the valve bodies are aligned in the opposite direction, there is a problem that a valve-applied applicator in which the valve bodies are mounted in the reverse direction is produced and the defective rate increases. Further, if the array abnormality detecting device is incorporated in the assembly process so as to prevent such defects, the assembly process is stopped and the productivity is reduced. An object of the present invention is to provide a valve-applied applicator having a valve body that does not cause a valve body alignment failure when aligning the valve bodies with an aligning machine such as a parts feeder machine in assembling the valve-applied applicator. .

[0007]

[Means for Solving the Problems]

 According to the present invention, a coating body accommodating chamber is formed inside, and a front body having a through hole is fixed to an opening of a container body having an opening at one end, and a metal having a seat portion on the inner surface of the tip is attached to the opening of the front body. A tubular body made of metal is fixed, and a valve mechanism is formed by abutting the valve portion on the seat portion inside the metallic tubular body. In a valved applicator arranged to urge forward by a repellant body, the valve body is characterized in that at least the tip portion is a heavy body, and the other portion including the valve portion is a light body. The main point is the applicator.

【Example】

 Hereinafter, the present invention will be described with reference to the accompanying drawings. FIG. 1 is a vertical cross-sectional view of a main part of a valved applicator showing an embodiment of the present invention. Reference numeral 1 is a precursor having a through hole 1a. The apex 1 is fixed to an opening of a container body (not shown) having an inside serving as a coating liquid storage chamber. The apex 1 has an annular groove 1b around the through hole 1a. Is forming.

The metal tubular body 2 is a hollow pipe-shaped member, and forms a tip hole 2a from the inside of the tip and a subsequent hole 2b having a diameter larger than the diameter of the tip hole 2a following the tip hole 2a. 2b, a continuous hole 2c having a larger diameter than the next hole 2b is formed. The metal tubular body 2 is fixed to the front body 1 by press-fitting the rear straight tube portion, which is the continuous hole 2c portion, into the annular groove 1b of the molded body 1.

The metal tubular body 2 is formed with a funnel-shaped seat portion 2d 1 whose diameter is expanded from the tip hole 2a to the next hole 2b.

The valve body 3 includes a tip portion 3a that projects outward from the tip hole 2a of the metallic tubular body 2, a convex R-shaped valve portion 3b that abuts the seat portion 2d, and a repellent body 4 described later. It is composed of a stepped portion 3c which serves as an abutting portion. Here, the tip portion 3a is a weight body 3d formed by turning or forging a metal material such as stainless steel, titanium, nickel silver, etc., and the other portion including the valve portion 3b is a light-weight processed resin material. It is the body 3e. A bag hole 3f for press-fitting the weight body 3d is formed at the tip of the lightweight body 3e, and the weight body 3d is press-fitted into the bag hole 3f. A small-diameter rod-shaped portion 3g extending to the through hole 1a of the front body 1 is formed behind the stepped portion 3c.

The elastic body 4 is a coil spring made of a metal wire rod. The outer diameter of the coil spring is smaller than that of the next hole 2b of the metal tubular body 2, and the inner diameter thereof is the same as or larger than that of the rod portion 3g of the valve body 3. The elastic body 4 is stretched between the step portion 3c of the valve body 3 and the front body 1.

The valve body 3 may be formed by molding the weight body 3d or the light weight body 3e individually and then joining the weight body 3d or the light weight body 3e. Molding (so-called insert molding) may be performed by molding.

The mold surface corresponding to the valve portion 3b of the valve body 3 must be smooth and have a perfect circle. The metal tubular body 2 and the front body 1 are firmly fixed to each other by a rib to form a retaining portion, but instead of the rib, the outer surface of the rear end of the metal tubular body 2 is rolled. (So-called knurling) may be formed and used as a retaining portion from the front body 1.

Further, as the metal tubular body 2, the one having the tip hole 2a, the next hole 2b, and the continuous hole 2c is shown, but the next hole 2b and the continuous hole 2c are the metal tubular body 2 The diameter may be the same as long as it can be sufficiently fixed to the apex 1.

Further, since the seat portion 2d of the metal tubular body 2 is a funnel type and the valve portion 3b of the valve body 3 is a convex R shape, the seat portion 2d and the valve portion 3b are in circumferential contact with each other. However, as long as it has a valve function, it may be set in various forms.

Since the tip portion 3a of the valve body 3 is the weight body 3d and the other portion including the valve portion 3b is formed of the lightweight body 3e made of resin, the center of gravity of the valve body 3 is large from the center. Since they are offset, the arrangement on the parts feeder machine can be aligned in the same direction. Further, since the surface of the valve portion 3b is smooth and is formed in a perfect circle, there is no sealing failure due to the metal working roughness of the valve portion compared to the case where the entire valve body is made of a metal material. Since it is a metal material and has a high hardness, even if the tip is thin, it is possible to further reduce the abrasion of the tip due to the continuous coating of the coating liquid.

FIG. 2 shows a second embodiment. In the valve body 13, the weight body 13d made of a metal material has a front cylindrical portion having a large diameter portion on the front side and a rear cylindrical portion having a small diameter portion on the rear side. The point ribs are formed by forging in places. The valve body 13 has a weight body 13d and a weight body 13e formed by insert molding. Since the weight body 13d is provided with point ribs, the weight body 13d does not come off from the light weight body 13e. The ratio of the large diameter portion to the small diameter portion is 2.0 or less, preferably 1.7 or less.

FIG. 3 shows a third embodiment. In this valve body 23, the weight body 23d has a T-shaped cross-section, the base is cylindrical, and a concave groove is formed around the entire circumference behind it. This valve body 23 is formed by insert molding of a weight body 23d and a light weight body 23e as in the second embodiment.

FIG. 4 shows a fourth embodiment. In the valve body 33, the weight body 33d is a sphere made of a hard material having a high specific gravity, such as cemented carbide, ultrafine grained cemented carbide, ruby, and ceramic, in addition to the above metals. This valve body 33 is formed by insert molding of a weight body 33d and a light weight body 33e as in the second embodiment. The valve body of the fourth embodiment has a smaller amount of wear of the tip when used as compared with the valve bodies of the first to third embodiments.

FIG. 5 shows a fifth embodiment. In the valve body 43, the weight body 43d is formed by drawing into a hemispherical shape. In this valve body 43, the light weight body 43e is press-fitted into the weight body 43d, and further, the light weight body 43c is present at one point or a plurality of points or the entire circumference from the outer peripheral side surface direction where the rear end of the weight body 43d is opened. It is formed by caulking in the state of being pressed or by insert molding of the weight body 43d and the light weight body 43c.

[0022]

[Effect of device]

 In the applicator with valve according to the present invention, since the weight body made of metal is arranged at the tip of the valve body, the position of the center of gravity of the valve body is not at the middle position (center) of the entire length but at the end, so that the parts feeder machine is used. When arranging with, it is easy to make the arranging direction constant, so that the valve body is not assembled in the opposite direction and the assembling machine does not stop. Also, with this valved applicator, the valve section is made of resin, so there is no sealing failure due to rough metal processing, and the tip of the valve body is made of metal, so even if it is used for a long period of time, It also has the advantages of low wear and low coating properties.
