Description

Writing tool

Technical Field

The utility model belongs to the technical field of the stationery technique and specifically relates to a writing tool.

Background

Common marking writing instruments include markers, highlighters, and whiteboard markers. For example, when reading books or extracting notes, a highlighter is used for marking important characters; when writing on a whiteboard, a whiteboard marker is generally used because it is easy to erase; when the labels are required to be retained for a long time in a paper box, a plastic bag, or the like, a marking pen is generally used.

As the pen points of the writing tool are made of fiber materials, when the pen cap is inserted and pulled out or writing is carried out, hands are easily dirtied by the fiber pen points. Meanwhile, when the fiber pen point is used for marking, the fiber pen point is thick and solid, characters can be blocked, people cannot mark a specific position correctly, and the situation that the mark is inclined or is coated more or less can occur.

Disclosure of Invention

A primary object of the present invention is to provide a writing instrument to solve the problem of the pen point dirtying the hand and marking inaccurately in the prior art.

In order to achieve the above object, the present invention provides a writing instrument, which comprises a pen body, a pen cap and a pen point, wherein a core wrap with ink is arranged in the pen body; the pen top is fixed at one end of the pen body in a sealing mode, and the refill core is fixed in the pen body; the pen point comprises a fiber core and a coating part, the fiber core is provided with a writing end and an ink supply end, the ink supply end is used for supplying ink, the writing end is used for writing, the coating part coats the axial periphery of the fiber core in the coating part, the coating part is made of transparent hard materials, and one end of the coating part penetrates through the pen item and is inserted into the cartridge.

Furthermore, one end of the pen item is arranged at one end of the pen body in an interference fit mode, the other end of the pen item is gradually drawn towards the central line of the writing end of the pen point, at least two protrusions are arranged on the inner wall of the other end of the pen item and correspond to the protrusions, and the coating portion is in interference fit with the protrusions. The existing pen point is integrally made of fiber materials, and the fiber has large friction force and smaller elasticity, so that the fiber pen point can be directly arranged in the pen item in an interference manner; for the pen point using transparent hard material as the cladding part, the hard material has small friction force and is hard, so that the pen point cannot be directly installed on the pen item with the existing structure.

Further, the coating part is made of an acrylic material. The coating part with acrylic force has good transparency, and when the coating part is processed, the acrylic material can tightly fix the fiber core and ensure that the ink can be smoothly led by the fiber core.

Further, the cross section of the fiber core is rectangular, and the cross section of the cladding part is oval or racetrack-shaped.

The fiber core is the writing part of nib, when needing to mark characters, the cross section of fiber core sets up the rectangle can make full use of the long limit of rectangle and highly align of characters, makes things convenient for the mark. When mass production is carried out, the fiber core is usually made to be very long, then a section of pen point length of the pen point is cut, the production capacity of the fiber core is improved, and the corresponding production efficiency is also improved. The cladding part is used for cladding the fiber core, when the cross section of the fiber core is rectangular, the cross section of the cladding part is optimally designed to be elliptical or racetrack-shaped when the material cost is saved and the cladding part is favorably arranged in a hole at one end of the pen.

Further, the fiber core and the cladding part are coaxially arranged, and the distance L1=0.5-1.5mm between the long side of the cross section of the fiber core and the long side of the cross section of the cladding part. Such an arrangement is more cost effective when the writing area of the fiber core is fixed.

Further, the fiber core and the cladding are coaxially arranged, and a distance L2=0.6-1.6mm between a short side of a cross section of the fiber core and a short side of a cross section of the cladding. Such an arrangement is more cost effective when the writing area of the fiber core is fixed.

Further, the cross section of the fiber core is circular, and the cross section of the cladding is circular. When the cross section of the fiber core is circular, the cross section of the cladding part is circular, so that the matching of the fiber core and the cladding part is facilitated, and the cost is saved; when the pen point is used for writing, the cross section of the fiber core is circular, so that characters can be written conveniently, and meanwhile, the production process flow is saved. When mass production is carried out, the fiber core is usually made to be very long, then a section of pen point length of the pen point is cut, the production capacity of the fiber core is improved, and the corresponding production efficiency is also improved.

Further, the fiber core and the cladding are coaxially arranged, and the radius of the cladding is larger than the radius difference R1=0.5-1.5mm of the fiber core. Such an arrangement is more cost effective when the writing area of the fiber core is fixed.

Furthermore, a visible part is arranged on the coating part at the other end of the fiber core, and characters blocked by the fiber core can be seen through the visible part according to the light reflection principle. The pen point of a general marking pen is made of fiber materials, when characters are marked, the fiber pen point usually covers the marked characters, so that a writer cannot accurately mark the characters and can only feel the characters, and deviation can occur in the marks frequently. The coating part of the writing end is provided with a visible part which can see characters covered by the fiber core by utilizing the light reflection principle, thereby solving the problem of marking deviation.

Compared with the prior art, the utility model has the advantages of the cladding portion adopts transparent hard material, and the user touches the outer cladding portion of nib carelessly and also can not make dirty hand, can range estimation mark characters's direction and height through the cladding portion edge simultaneously, has improved the accuracy of mark.
