Claims

[Scope of utility model registration request]

A pen barrel having a pen nib opening at the lower end, a push-down part at the upper end, and a seal valve installed in the hollow part, and a pen core holding part with the pen nib exposed at the lower end of the ink chamber, and a pen main part attached to the pen barrel so as to be able to advance and retreat while being biased backward, and a pair of coils having different spring constants, which are fitted onto the pen nib holding part to accommodate the pen tip in the retracted position. It consists of a mantle tube that is elastically supported by a spring between the inner surface of the pen barrel cylinder and the main body of the pen so that it can move forward and backward, and the seal valve has a seal lip that presses and closes the insertion opening in the center part, and the valve can be retracted. The seal valve is opened by interlocking the lowering of the main body of the pen with the push-down part to form a nib passage, and then the pen nib is pushed down to open the nib opening. A magic pen featuring a structure that sticks out and holds it.
