Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a paint marker using pigment ink.

[Prior art and its problems]

Paint markers that use pigment ink,
Because the ink has a high viscosity and dries quickly, a valve mechanism is installed inside the pen body that protrudes from the tip opening and is pushed back against the paper surface, thereby connecting it to the rear end of the pen body. The valve moves back to open the valve mechanism, and the ink in the ink storage tube is guided to the pen body in the amount necessary for writing.

By the way, this type of paint marker usually has a tip screwed into the opening of a metal ink storage tube, and a separately manufactured valve, valve seat, biasing spring, etc. is attached to the tip of the ink storage tube. A valve mechanism was installed. Therefore, there were problems in that the number of parts was large and the structure was complicated.

[Purpose of invention]

Therefore, an object of the present invention is to provide a paint marker with a small number of parts and a simple structure.

[Structure of the idea]

The paint marker of the present invention presses the pen body made of a permeable material that protrudes from the opening at the tip of a synthetic resin ink storage tube containing quick-drying pigment ink, and retracts the valve connected to the rear end of the pen body. In a paint marker that opens a valve mechanism disposed inside and guides ink to the pen body, the valve seat where the valve seats when the valve mechanism closes is placed in the middle of the ink storage tube. It is characterized by being integrally molded with.

〔Example〕

The present invention will be specifically described below based on embodiments shown in the drawings.

The drawing shows a double-headed paint marker with different thicknesses of pen bodies protruding from both ends to produce two types of handwriting, but the ink storage tube 1, which stores quick-drying pigment ink inside, is made of synthetic resin. , the pen body sliding portion 11 at the tip is integrally molded. A plurality of vertical air grooves 12 are formed inside the pen sliding portion 11 . A tapered portion is integrally formed on the inner surface of the midsection of the ink storage tube 1, and this is the valve seat portion 13. A pen body 31 having a large diameter, such as a felt pen made of a permeable material such as a fiber body, is slidably fitted into the inner hole of the pen body sliding portion 11 . and,
An ink storage body 41 is wrapped around the pen body 31, and serves to prevent ink from dripping and to gradually supply ink to the outer periphery of the pen body 31. A valve 51 is provided at the valve seat portion 13.
are arranged, and both constitute a valve mechanism, and the base end surface of the pen body 31 is in contact with this valve 51.

A synthetic resin tip 2 is screwed into the rear end opening of the ink storage tube 1. This tip 2 also serves as a lid for the ink storage tube 1, and its structure is almost the same as the tip of the ink storage tube 1.
That is, a tapered second valve seat portion 23 is formed,
An air groove 22 is formed on the inner surface of the pen body sliding portion 21. A second pen body 32 having a slightly smaller diameter is slidably fitted into the pen body sliding portion 21.
An ink storage body 42 is wound around this.
The second valve 52 is disposed at the second valve seat portion 23, and a biasing spring 6 is disposed between the valve 51 and the second valve 52.
is disposed, and this biasing force causes the valve 51 and the second valve 52 to move toward the valve seat portion 13 and the second valve seat portion 2, respectively.
3, seated in a liquid-tight manner.

Therefore, when writing, when one of the pen bodies is pressed against the paper surface and retreated, the valve mechanism opens and ink flows down toward the pen body. This ink is then transferred to the tip of the pen body and used for writing. Once the ink flowing down from the valve mechanism is consumed, the pressing operation is repeated again to write.

[Effect of idea]

As explained above, in the paint marker of the present invention, the valve seat on which the valve sits when the valve mechanism closes is molded integrally with the ink storage tube in the midsection of the ink storage tube. There is no need to prepare a mechanism, the number of parts is small, and a paint marker with a simple structure can be obtained.

Claims (1)

[Scope of Claim for Utility Model Registration] A pen body 31 made of a permeable material protruding from the tip opening of a synthetic resin ink storage tube 1 containing quick-drying pigment ink is pressed and connected to the rear end of the pen body 31. In a paint marker in which the valve 51 is retracted, thereby opening a valve mechanism disposed inside and guiding ink to the pen body 31, the valve seat 13 on which the valve 51 is seated is inked when the valve mechanism is closed. A paint marker characterized in that the middle part of the storage tube 1 is molded integrally with the ink storage tube 1.
