Description

[Detailed description of the invention] (Field of industrial application) The present invention relates to a pen tip structure of an applicator that can supply and apply fluid stored in a barrel to the pen tip at the tip of the barrel. It is.

(Prior art and its problems) As a pen tip of an applicator that can supply and apply the fluid stored in the barrel to the pen tip at the tip of the barrel, as shown in Fig. 4, a fluid storage chamber is used. A fixed tube 103 is fixed to the tip of the shaft tube 102 provided with the fixed tube 101 by press fitting, adhesive, etc., and an adhesive is applied to substantially the entire outer surface of the column 104 protruding from the fixed tube 103.
A pen nib 10 having a hole or a cut in the column part 104
A structure is known in which 5 is attached by being fitted externally. As the pen nib 105, a sponge or the like containing a fluid and capable of elastically applying the fluid is used. ,
The fluid in the fluid storage chamber 101 is supplied from the opening at the tip of the column 104 .

However, with the conventional pen nib structure mentioned above,
Since the pen nib 105 is fixed with an adhesive applied to substantially the entire outer surface of the column 104, the adhesive impregnates the external fitting part of the nib 105, solidifies the part, and improves the elasticity of the nib 105. Coupled with the fact that the column 104 has only a tip opening, the supplied fluid concentrates on the tip of the pen nib 105, and for example, when the fluid used is a highly viscous liquid, the liquid However, there have been problems in that the fluid cannot be diffused and supplied to the tip of the pen, resulting in smearing and other problems, which hinders coating.

(Purpose of the invention) This invention was created in view of the problems mentioned above.
An applicator pen that contains a fluid and is capable of applying the fluid elastically without impairing the application elasticity of the pen tip, and that can diffuse and supply the fluid to the pen tip to perform good application. The purpose is to provide an advanced structure.

(Structure of the invention) The present invention has a pen nib that is externally fitted and fixed by adhesive to the column of a fixed tube fixedly arranged at the tip of the barrel.
In an applicator that is capable of supplying the fluid stored in the barrel through a communication hole continuously formed in a fixed pipe and a column, a supply hole communicating with the communication hole is provided in the side wall of the column. The gist of the invention is a pen nib structure of an applicator, characterized in that a non-adhesive area between the pen nib and a pillar part is provided at a position near the supply hole including the supply hole.

(Example) Hereinafter, the present invention will be described in detail based on an example shown in the accompanying drawings.

1 and 2, reference numeral 1 is a barrel provided with a fluid storage chamber 2 for storing liquids and powders for writing, cosmetics, etc., and the tip of the barrel 1 has approximately A fixed pipe 4 having a pillar part 3 in the center is press-fitted,
It is fixed by adhesive etc. A communication hole 6 is continuously formed in the column 3 and the fixed tube 4 to communicate with at least one (four in the figure) supply holes 5 provided on the side wall of the tip of the column 3. 7 is a pen nib made of a sponge or the like that contains a fluid and can elastically apply the fluid, and has a recess 8 such as a hole or cut that can be fitted onto the column 3; The pen tip 7 has its rear portion externally attached to the column 3 by adhesive so as to have a non-adhesive region l which is in a non-adhesive state with the column 3 at a position near the supply hole 5 provided on the side wall of the tip of the column 3. It is fixed in place.

(Function) Hereinafter, the function of supplying fluid to the pen tip in the above-mentioned embodiment will be explained.

The fluid stored in the fluid storage chamber 2 is pushed through the flow hole 6 by direct pressure of the shaft cylinder 1 or the operation of an appropriate pressure means.
It is supplied to the pen tip 7 through the supply hole 5 provided in the tip side wall of the column 3. The fluid that can flow out from the supply hole 5 spreads over the entire non-adhesive area 1 and simultaneously flows into the pen tip 7, that is, it is almost uniformly diffused and supplied to the entire non-adhesive area 1.

In the example shown in FIG. 1, in order to improve the diffusion and supply of the fluid to the pen tip 7,
Although a step 9 is provided on the outer surface of the column 3 and a gap is created between the front part of the step 9 and the inner surface of the nib 7, as shown in FIG. The same effect can be obtained without providing the stepped portion 9 by making the inner surface of the pen tip 7, which corresponds to the non-adhesive region 1, come into close contact with the outer surface of the column portion 3.

(Effects of the invention) As described above, in the present invention, the fluid stored in the barrel is transferred to the pen tip which is fixed by adhesive to the column of the fixed tube fixed at the tip of the barrel. and an applicator capable of supplying through a communication hole continuously formed in the column, wherein a supply hole communicating with the communication hole is provided in the side wall of the column, and the supply hole including the supply hole Since a non-adhesive area is provided between the pen tip and the column in the vicinity, the application elasticity of the pen tip is not impaired, and the fluid can flow out from the supply hole provided on the side wall of the column via the circulation hole. It can be diffused and supplied to the pen tip, allowing good fluid application.

In the above embodiment, the supply hole is provided at the tip of the side wall of the column, but the supply hole may be continuous in the longitudinal direction of the side wall of the column depending on the size of the non-bonded area. The position and number can be changed in various ways, such as by providing a plurality of holes.
