From the brushes and quills that need to be stained with ink at the beginning, they have gradually developed ball pens that can store ink inside. , fountain pen, highlighter or signature pen, which is equipped with a structure that can store ink inside the pen, so that people can use the pen to write continuously without frequent ink contamination, which has better convenience.

However, the ink pen utilizes the pen core to export the internal ink storage for people to write. When the pen core is exposed to the air for a long time, the pen core is easily affected by the volatilization effect and the ink in the pen core is dried up and hardened. As a result, when people use ink pens to write, the ink cannot be smoothly exported through the refill. Therefore, manufacturers have developed ink pens with caps that are common in daily life. Please refer to the tenth picture, the front side of the pen tube A A refill A1 is provided, and a cap A2 is provided on the rear side of the barrel A, and a cap B that can be sleeved and fixed on the outside of the barrel A to cover the refill A1 is provided.

When people use one hand to write, they don't need to take the pen cover B with the other hand. Take off the cover B, and then put it back on the outside of the refill A1 of the pen tube A. If people forget to cover the cover B with the refill A1 of the pen tube A, the ink in the refill A1 will be produced due to the volatilization effect. Drying and hardening, and when people use ink pens, if they place the cap B on the table, it is easy to push the cap B down during the operation, and the cap B is crushed or lost. Or when using an ink pen, pull out the cap B from the pen tube A, and after using the pen, put the pen tube A on the table directly, that is, forget to cover the pen B again, resulting in the front of the pen tube A The refill A1 is easy to dry out, which is an inconvenience that often occurs when using pens.

The above-mentioned customary ink pens with pen caps still have many deficiencies to be improved during actual use, such as:

(1) If the cap B of the ink pen and the barrel A of the ink pen are of a separate design, the cap B must be removed every time the ink pen is used, and the cap B must be put back on after use, and if the cap is forgotten B, and cause the ink of the refill A1 to dry up and harden due to the volatilization effect, causing the ink pen to no longer circulate smoothly, and can no longer be used for writing.

(2) The pen cap B is fitted and fixed to the pen tube A to form a positioning. When the pen cap B is frequently pulled out of the pen tube A, the inside of the pen cap B will be worn or deformed, resulting in the failure of the pen cap B to be fixed. In the pen tube A, the pen cap B is easy to loosen, fall and be lost.
