Description

Mini ballpen {mini ballpen}

The present invention relates to a mini ballpoint pen that is small in size and easy to carry, and more particularly, a ballpoint pen tip having a ballpoint pen tip coupled thereto.

It relates to a mini-ballpoint pen, characterized in that it comprises a built-in body, and a cap for receiving the body and hinged to one end of the body.

In general, a ballpoint pen widely used is composed of a cylindrical body and a ballpoint pen inserted into the body. However, the ball pen shim may be selectively drawn in or withdrawn from the body, or the ball pen shim protruding from the body may be accommodated as a cap in order to prevent clothes such as clothes being discarded by the ink contained in the ball pen nib when carrying the ball pen. . Among them, as a method for allowing the ball pen nib to be selectively withdrawn and withdrawn from the body, a separate button cap was generally used.

The present invention for solving such a problem can greatly improve the portability by reducing the length of the ballpoint pen when carrying, the user can smoothly grip the ballpoint pen by lengthening the length of the ballpoint pen when writing, It is an object of the present invention to provide a mini ballpoint pen capable of withdrawing and withdrawing a ballpoint pen core from a ballpoint pen body without manipulation.

As described above, the mini-ballpoint pen of the present invention is composed of a body having a ball pen core and a cap for accommodating the body and hinged to one end of the body, thereby greatly reducing the length of the ball-point pen when carrying, further improving portability. When writing, the body can be extended from the cap to extend the length of the ball pen, so that the user can smoothly grasp the ball pen to write without inconvenience. And by having a cam on one side of the hinge shaft for hinge coupling the cap and the body, the ball pen tip of the ball pen core embedded in the body is drawn out through the drawing hole formed in the upper surface of the body as the body rotates, the ball pen by a separate operation as conventional The hassle of drawing the ballpoint pen tip from the body is eliminated. In addition, the ball pen nib accommodates the other end of the ball pen nib, and is further provided with a guide piece which is in line contact or surface contact with the cam. It can be prevented from slipping to one side of the cam has an effect that can effectively withdraw the ballpoint pen tip to the drawing hole of the body.
