[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a nozzle for discharging and applying a coating agent having fluidity such as a medicine, a cosmetic, an adhesive, a paint, or a brightener.

[0002]

2. Description of the Related Art Conventionally, as an invention of this kind, for example, as a lip medicine applicator, a paste-like material in a container is discharged from a dispenser attached to a mouth portion of the container, and an application surface of the dispenser is used. It is known to apply it to the human body (for example, JP-A-63-46175).

As a nozzle for applying the adhesive, a spatula-shaped nozzle having an adhesive outlet on the application surface is known (Japanese Utility Model Laid-Open No. 63-13840).

[0004]

However, in the above-mentioned prior art, the periphery of the application surface is sharp or angular, and the application surface is moved in the sharp or angular direction. If you try to do so, it may be caught, so the direction of movement of the nozzle application surface is limited,
There was a problem that application was difficult.

SUMMARY OF THE INVENTION An object of the present invention is to provide a nozzle for applying and discharging a coating agent which can apply the coating without being restricted by the moving direction of the nozzle coating surface.

[0006]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A first embodiment of a nozzle for applying and discharging a coating agent according to the present invention will be described below with reference to FIGS. The nozzle 1 for applying and discharging the coating material includes a mounting portion 3 for mounting the coating material container 2, a nozzle body 4 extending from the mounting portion 3, and a coating surface 5 a formed at a tip 5 of the nozzle body 4. Have. One of the nozzle holes 6 penetrating the nozzle body 4 is opened in the application surface 5 a, and the other is opened in the inner bottom surface of the mounting portion 3.

The outer shape of the nozzle main body 4 is not limited to a truncated cone as shown in the figure, but may be a cylinder, a prism, or the like.
m, preferably 20 to 60 mm, outer diameter 1 to 13 mm, preferably 3 to 8 mm. Further, the shape of the nozzle hole 6 is not limited to the tapered nozzle, but may be the same hole diameter throughout the divergent nozzle or the entire length. Further, the nozzle main body 4 is not limited to a form extending straight as shown in the figure,
It may be slightly curved (not shown).

The coating surface 5a of the tip 5 is formed by a curved surface having a rounded periphery. Of course, as shown in the example of FIG. 1, not only the periphery of the application surface 5a but also the entire tip 5 may be rounded. In this case, regarding the range of the application surface 5a,
The term “application surface” in this specification means a surface used for applying the application agent discharged from the nozzle holes 6 to the application surface, and includes not only a flat surface but also a curved surface. The application surface 5a is provided on the nozzle body 4
Is preferably inclined with respect to the central axis of the coating. In this case, the angle range θ of the application surface 5a with respect to the nozzle axis is 5 to 90 °, preferably 20 to 90 °. Of course, this inclined surface can also be a curved surface having a gentle curve. The application surface 5a may be a smooth concave or convex surface as a whole from the center to the periphery of the application surface, and in the example of FIG.

The tip 5 can be formed by bending from the nozzle body 4 as shown in the figure. The bending angle range in this case is equivalent to the inclination angle range θ when the application surface 5a is inclined. By bending the distal end portion 5 in this manner, for example, even in a complicated place such as the inner cheek stomatitis on the back side of the back teeth, the bent portion 45 by the bending bypasses the obstacle such as the back teeth. A drug or the like can be applied. The length L of the tip 5 is 2
２０20 mm, preferably 3-10 mm.

The mounting portion 3 can be appropriately formed according to the shape of the mouth of the coating material container 2. For example, when the discharge port of the coating material container 2 is a male screw, it is screwed into the male screw. A female screw is formed on the inner surface of the mounting portion 3.

The nozzle 1 for applying and discharging the coating material has a mounting portion 3
A cap 7 that covers the entire part except for (7) can be attached. The cap 7 has a flange 8 formed near the mounting portion 3 of the nozzle body 4, and an annular recess 9 in which the flange 8 is fitted is formed on the inner peripheral surface near the opening end of the cap 7. The cooperation between the annular recess 8 and the annular recess 9 allows the cap 7 to be airtightly fitted to the nozzle body 4. The means for fitting the cap 7 and the nozzle body 4 may be, for example, screw engagement. The cap 7 functions to block the coating agent from the outside air. The cap 7 is preferably made of a transparent material so that the inside can be seen through.

In the nozzle 1 for applying and discharging a coating agent having the above-described configuration, the lid 2b is removed from the container 2 containing a flowable coating agent such as a medicine, an adhesive, a cosmetic material, a paint, or a gloss material. Then, the mounting portion 3 is attached to the discharge port 2a of the container 2.
The coating agent in the container 2 is discharged to the coating surface through the nozzle hole 6 and is provided for coating. Of course, the cap 7 and the nozzle 1 for applying and discharging the coating material can be attached to the coating material container 2 in advance and used as an applicator for sale.

Since the periphery of the application surface 5a is formed by a rounded curved surface, the application agent can be applied to the application surface without being restricted in the moving direction of the application surface 5a relative to the application surface as in the above-mentioned prior art. Can be spread.

If the nozzle body 4 has the above dimensions, the coating surface 5a can be applied to a narrow place such as between the gum inside the oral cavity and the inside of the cheek, in the nasal cavity, or between the toes. It can be sent and is suitable for applying medicines for stomatitis and medicines for athlete's foot.

Next, a second embodiment of the nozzle for applying and discharging the coating agent according to the present invention will be described below with reference to FIG. The same parts as those in the first embodiment are denoted by the same reference numerals, and detailed description thereof will be omitted.

In this example, the application surface 5a extends laterally from the tip of the nozzle body 4. By expanding the application surface 5a to increase the area for application in this manner, it is suitable for a case where the area to be applied is large or a case where a large amount of application agent is applied. Alternatively, the periphery of the nozzle hole of the application surface 5a may be slightly concave to form a concave curved surface, so that the application agent can be applied while being accumulated in the concave portion at the time of application. When the present nozzle is used for a stomatitis coating, the width W of the tip 5 is preferably 1 to 20 mm, and more preferably 3 to 13 mm.

With respect to the nozzle for applying and discharging the coating agent of the second embodiment, an experimental example in which the easiness of applying the agent to the stomatitis using the samples A to H in which the dimensions of the respective parts are changed is described below. It is shown in the table.

[0023]

[Table 1]

The ease of application △ ○ △ × in the table means “◎: very easy to apply”, “○: easy to apply”, “△: slightly difficult to apply”, and “×: difficult to apply”. The “outer diameter of the nozzle body” is the outer diameter near the tip of the nozzle body.

In the above table, the numerical values of the dimensions marked with * are factors that hinder the ease of application. That is, when the length of the nozzle main body is shorter than 15 mm, and when the outer diameter of the nozzle main body exceeds 13 mm, it becomes difficult to apply any ink.

[0026]

As is apparent from the above description, according to the coating agent discharge application nozzle according to the present invention, application can be performed without being restricted by the moving direction of the nozzle application surface.
