Cap for writing tool

Abstract

The present invention provides a instrument pen cap for writing which improves buffering effect and prevents generating pen cocoon as well as makes the writing tool insert easily and increases the cling degree with the writing tool, thus implement writing stably. In the pen cap 1 which suits on the axis of the writing tool P and possesses cylinder-shape spring pen cap main body 2,many small independent warts 3 intersperses on the internal circle surface 2a of the given spring pen cap main body2.

Description

technical field [0001] The present invention relates to a pen case for writing instruments used to fit over shafts of writing instruments such as pencils and ballpoint pens. Background technique [0002] Among the existing pen covers for writing instruments, the pen covers only consist of a cylindrical elastic pen cover main body, and the cushioning effect when it is set on the shaft body of the writing instrument is only based on the elastic effect of the thickness of the elastic pen cover main body, so the cushioning is insufficient. A sufficient effect cannot be expected to prevent the generation of pen calluses. [0003] Therefore, a pen cover is disclosed. As shown in FIG. 6, on the inner peripheral surface (02a) of the cylindrical elastic pen cover main body (02) constituting the writing instrument pen cover (01), due to the continuous A lot of grooves (03) are formed in the direction, which improves the cushioning effect when it is set in a hexagonal prism writing in...

Problems solved by technology

[0005] In addition, when the writing instrument is in the shape of a corner, there will be gaps between the flat sides of the corner and the grooves (03) facing it, which will reduce the closeness of the corner and make it difficult to write stably.

[0006] Moreover, when the inner diameter of the elastic pen case main body (02) is enlarged in order to make the writing instrument easy to insert into the elastic pen case main body (02), the degree of closeness to the writing instrument will be further reduced, and stable writing cannot be performed.
