Definitions

• the present invention has a viscosity 5 0 ⁇ 1 5 0 c PS correction fluids, paints, cosmetics, and ⁇ the application destination of coating liquid accommodating the valved applicator such as Lee Nki, especially thin linear coating
• the present invention relates to an application destination of a valve-equipped applicator in which a tip is formed of a metal tubular body so as to be suitable for performing. Background technology
• a valve-equipped applicator comprising a valve body urged forward to press against a seat is known.
• This type of valve-equipped applicator has a structure in which when the valve is moved backward, the coating liquid passes through the gap between the seat and the valve, and flows out from the gap between the tip end hole and the applicator. Therefore, it has the characteristic that a relatively narrow coating mark can be obtained, but in recent years, there has been a demand in the market for a valve-coated coating tool capable of obtaining a finer coating mark.
• the tip of the forehead may be made thinner or the forehead tip hole may be made smaller.
• the tip Since the thickness of the part must be very thin, it is necessary to use a corrosion-resistant metal material such as stainless steel from the viewpoint of strength and corrosiveness. As a general rule, turning (that is, processing performed while rotating a workpiece and / or a cutting tool) is employed.
• the contact portion between the valve seat and the valve portion is made, for example, a mirror surface to form a complete hermetic carbuncle, the leakage of the coating liquid does not occur.
• the valve is an outer surface, it is possible to smooth the surface.However, especially the seat is an inner surface. It is very difficult to perform the processing to form, and there is a problem that the leakage of the coating solution cannot be completely eliminated. Disclosure of the invention
• an object of the present invention is that practically no coating liquid leakage occurs even if the valve mechanism between the valve seat and the valve section is not completely sealed.
• the purpose is to provide the application destination of the applicator with valve.
• the gist of the present invention is to provide a metal tubular tip body having a seat formed inside the rear end of the tip hole, and a coating portion formed by the tip hole.
• the application destination of the valve-equipped applicator comprising a valve body which is protruded and urged forward so as to press the valve part against the seat part. This is the application destination of the valve-equipped applicator characterized in that it is set to 0.8 mJ2 or less per second in O kg / of.
• a metal tubular tip body having a seat portion formed inside the rear end of the tip hole, and the tip hole coating portion is protruded.
• the valve body is urged forward to press the valve portion against the seat portion.

• a metal or resin valve element 14 biased forward is arranged, but metal is preferred in consideration of wear resistance, and in particular, stainless steel, nickel silver, brass, and charcoal Preference is preferred.
• a valve body moving mechanism may be provided on the side surface or the rear end of the main body as conventionally known, and may be of a side pressing type or a rear end pressing type.
• the feature of the present invention is that when the coating destination is closed (i.e., the repellency of the repellent body, the valve in which the valve is pressed against the seat), the air flow rate is 1.0 kg. This is the point where it was set to 0.8 m ⁇ / s or less.
• a method of secondary processing the seat surface can be adopted. As a secondary processing method, after the seat is formed, the coaxial push pin is brought into contact with the seat, so that the peaks and valleys formed on the seat and the boundary between the tip hole and the seat are formed. Method of crushing the edge of the seat, and pressing the off-axis push pin against the seat to crush the peaks and valleys formed on the seat and the edge of the boundary between the tip hole and the seat.

• the processing length in the longitudinal direction may be a part of the seat.
• the air flow rate was measured and calculated as follows.
• the application destination of the applicator with a valve obtained according to the present invention is as shown in FIG. 1, that is, the valve body is inserted into the forehead, and the valve body is pressed forward with a resilient body to open the valve. With the seat pressed against the seat, connect an air compressor to the rear end of the body and apply 1. O kgZoi pressure. Next, connect a pipe to the tip of the forehead, collect the air flowing out of the tip of the forehead with a female cylinder for 20 seconds, measure the amount of air flowing out, and calculate the air flow rate per second.
