Abstract

(57) [Summary] [Purpose] This invention relates to a shaft body for writing instruments such as ballpoint pens and mechanical pencils, or containers for cosmetics such as lipstick and eyebrow ink. [Structure] The shaft body is made of a material such as plastic and has a transparent cylindrical shape, and its outer surface is formed into a cylindrical surface and the inside surface is formed into a rectangular hole. The seller or brand name, etc. can be printed and displayed in a predetermined position at high speed, and the transparency of the shaft, the cylindrical surface on the outer surface, and the square hole on the inner surface give it a crystal-like shine. The writing instrument mechanism is guided by the hole, and the writing instrument mechanism is slid without rotating, so that the lead or the like can be reliably and smoothly fed out from the tip.

Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This invention is suitable for writing instruments such as ballpoint pens and mechanical pencils, or for writing instruments such as lipstick and eyebrow ink. This relates to the shaft of cosmetic containers, etc.

0002

[Conventional technology]

Conventionally, in writing instruments such as office ballpoint pens and mechanical pencils, the shaft body is transparent. Made of bright plastic, with a polyhedral outer surface and a cylindrical shape with circular holes. Or, a pipe-shaped shaft made of opaque plastic with a circular shape inside and outside is known. It is being

0003

[Problem that the idea aims to solve]

However, the former shaft body has a transparent polyhedron that refracts light rays and gives it a shine. This type of writing instrument shaft is generally manufactured by the manufacturer or For sellers, necessary information such as manufacturer indication, seller indication, or brand name etc. It is customary to display this by continuously rolling the shaft. Because hot stamp printing or silk screen printing is used on If the shaft is a polyhedron, it is difficult to control accurately printing on one predetermined surface, and Depending on the size of this surface, the size of characters and marks that can be printed is limited. be. In addition, although the latter shaft solves the problem as a printing display method, the shaft is defective. Since it was transparent, there was no shine caused by refraction of light rays. Therefore, this idea was made to solve the problems of the conventional shaft body mentioned above. Not only can it be printed in a predetermined position at high speed, it can also produce a crystal-like shine. , a shaft of a writing instrument, etc. that can reliably and smoothly guide the writing instrument mechanism inside the shaft. It's about getting.

[Means to solve the problem] As a means to achieve this, this invention uses transparent plastic materials etc. The outer surface of the tube is formed into a cylindrical surface, and the inner surface is formed into a square hole. It is.

【Example】

An example of a specific configuration of this invention will be described in detail below with reference to the drawings. Figures 1 to 3 show a first embodiment in which the shaft of this invention is used in a knock mechanical pencil. 1 is a cylindrical shaft made of material such as transparent plastic; 1 has an outer surface with a circular cross section and a cylindrical surface 2, and an inner surface with a hexagonal cross section. A square hole 3 is formed. Furthermore, connecting screws are formed on the tip and rear ends, respectively. Screw the tip 5 onto the connecting screw on the leading end side, and screw the stopper with clip 6 onto the connecting screw on the rear end side. do. Then, slide the knock sharp mechanism 7 into the square hole 3 between the tip 5 and the clasp 6. It can be fitted and installed so that it can be installed easily. Also, on the outer surface of the cylindrical surface 2 of the shaft body 1, the manufacturer, seller, Hot stamp printing or silk screen printing of letters and marks such as brand names etc. Display by printing. With this structure, the shaft body 1 has a knock sharp in the rectangular hole 3. By knocking the rear end of the mechanism 7, the knock sharpening mechanism 7 locks into the square hole 3. It is possible to slide the lead out from the lead metal 5 without rotating when it is idle. . The outer surface of the shaft body 1 is formed into a cylindrical surface 2, and the inner surface is formed into a hexagonal square hole 3. Therefore, each side 4 of the square hole 3 and the arc surface of the outer surface of the cylindrical surface 2 form a convex surface. It has a lens-like structure that refracts light rays and shines like a crystal, giving it a beautiful appearance. Ru. Furthermore, the letters, marks, etc. 8 displayed on the outer surface of the cylindrical surface 2 of the shaft body 1 are changed in size. It can be displayed reliably in a predetermined position without any restrictions. In addition, a ring-shaped uneven portion 9 is formed on the outer surface of the cylindrical surface 2 on the tip side of the shaft body 1, This not only prevents slipping when writing, but also prevents the convexity between the square hole 3 and the cylindrical surface 2 on the outer surface. In addition to the lens effect, the ring-shaped uneven portion 9 makes the crystal-like shine even stronger. be converted into

[0006] FIG. 4 shows a second embodiment of the shaft body of this invention, in which the square hole of the shaft body 11 is formed into a pentagonal star. It is formed in the shaped hole 13. As a result, the arc surface of the cylindrical surface 12 on the outer surface and each side 14 of the star-shaped hole 13 Furthermore, the light rays are refracted in a complicated manner, increasing the crystal-like shine and creating an even more beautiful appearance. It is something that

[0007] FIG. 5 shows a third embodiment of the shaft body of this invention, in which the shaft body 21 is made of transparent plastic. By mixing fine metal powder 22 into the material, each side 25 of the square hole 24 and In addition to the convex lens formed by the arc surface of the cylindrical surface 23 on the outer surface, the light of this fine metal powder 22 The reflection of the lines further enhances the crystal-like shine, making it extremely beautiful. I can do that.

[0008] FIG. 6 shows a fourth embodiment of the shaft body of this invention, in which the rectangular hole 32 of the shaft body 31 is filled with metal vapor. When a reflective layer 33 such as a deposited film or a metal coating layer is formed, the crystal-like shine is further increased. At the same time, it is possible to hide the knock sharp mechanism fitted and installed in the square hole 32. Wear.

[0009] In addition, the knock sharp mechanism fitted into the square hole in the various embodiments described above When displaying characters, marks, etc., the convex lens effect between the square hole and the cylindrical surface on the outer surface The characters, marks, etc. can be enlarged and observed from the outside. In addition, the shaft of this invention is not limited to writing instruments, but also the shaft of cosmetic containers such as lipstick and eyebrow ink. It can also be used for. Further, the transparency of the shaft body is not limited to colorless, and may be variously colored.

[Effect of the idea]

As described above in detail regarding various embodiments, the shaft body of this invention has a cylindrical outer surface. It is shaped like a shape, so the manufacturer, seller, brand name, etc. can be printed When printing, it is possible to continuously print at a predetermined position at high speed while rolling the shaft. The characters and marks displayed on the screen are not limited by size and must be displayed securely in the designated position. be able to. In addition, the shaft body is transparent cylindrical, the outer surface is cylindrical, and the inner surface has a square hole. Because of this, it has a convex shape due to each side of the square hole and the arc surface of the cylindrical surface on the outer surface. It has a lens-like structure that refracts light rays and shines like a crystal, giving it a beautiful appearance. Moreover, the writing instrument mechanism inside the square hole is guided by the square hole and can be slid without rotating. It is inexpensive and allows the core etc. to be drawn out reliably and smoothly from the tip by idling. It is easy to use and has various effects.
