Description

A kind of pen

Technical field

The utility model belongs to stationery apparatus technical field, relates in particular to a kind of pen.

Background technology

Pen is the writing implement that people generally use, and it was invented in 19 beginnings of the century.Pen have write slick and sly and flexible, suitable Liu Chang advantage.Pen sees through the shaft of a writing brush splendid attire ink (mostly being black or blue) of hollow, by gravity and capillarity, writes via the nib of duck-beak type again.Present pen all is water absorption type, just can fill the hollow shaft of a writing brush after using ink again.This type of pen is owing to need fill ink, and filling ink is also cumbersome, accidentally will make ink be stained with on the object such as clothes, makes that the article such as clothing of being stained with ink are not easy to clean very much.And, because the pen of water absorption type when drawing ink, owing to each atmospheric pressure that pushes in the hollow shaft of a writing brush that forms is all different, so it is also different to draw the amount of ink, often need repeatedly be drawn cumbersome.Because above defective makes that the utilization rate of pen is more and more lower.

Summary of the invention

The purpose of this utility model is to solve above-described technical problem, and a kind of pen is provided, and its technical scheme is as follows:

A kind of pen, comprise nib, pen container and the cap for brush, it is characterized in that, be provided with pen core in the described pen container, described pen core is a hollow tube, the end sealing of described pen core, the other end opening of described pen core, the opening part of described pen core links to each other with nib, and sealing one end of described pen core is close to mutually with the cap for brush.

Optimal way is to be positioned at opening one end place on the described pen core and to be provided with screw thread.

The pen that the utility model provides, in use, pen core can be changed.In the general pen core ink is housed, uses sealed by film at opening part then.In use, only need aim at the mouth of pipe that ink is advanced in the Pen nib upper end to the openend of pen core, make the mouth of pipe puncture thin layer and enter in the pen core, thereby make the ink in the pen core enter into nib.If after a pen core uses, only need take off this pen core, then replace with a new pen core just passable.Use of the present utility model is similar to the replacement of Signing refill and uses.

Be positioned at opening one end place on the pen core described in the utility model and be provided with screw thread.The upper end of the Pen nib that has is provided with internal thread, thereby makes pen core and nib interfix by screw thread, makes that both connections are more stable, is conducive to ink.

The utility model makes the pen core of pen can carry out freely replacing, and does not need to carry out loaded down with trivial details blotting, and is simple to operation, is conducive to popularize.
