Description:
BACKGROUND OF THE INVENTION 
       [0001]    1. Field of the Invention 
         [0002]    The Invention is related to an ink-pen, more particular to an improvement of ink-pen. 
         [0003]    2. Description of the Prior Art 
         [0004]    Conventionally, a pen cap is used to enclose the pen tip of an ink-pen for protecting the pen tip as well as for preventing the ink from evaporating so as to reduce the ink consumption speed. 
         [0005]    Occasionally, the ink-pen is not capped or even the pen cap is lost due to user&#39;s personal habit or being forgotten. While the ink-pen is used for the next time, the ink remained in the pen is not sufficient for the writing purpose, which causes inconveniences, such as the needs to suddenly change the writing equipment or to refill the ink-pen. It results in not only the waste of resources but also inconveniences in use. When the conventional ink-pen is carried, the pen cap sometimes will be removed from the ink-pen due to user&#39;s body movements. The cloths of the user often get stains from such situations. Therefore, an improved ink-pen is required to resolve the above-mentioned problems for the traditional ink-pen. 
       SUMMARY OF THE INVENTION 
       [0006]    In light of the above-mentioned background and in order to fulfill the need of the industry, the present invention provides an improvement of ink-pen to resolve the above-mentioned deficiencies of the conventional ink-pen. 
         [0007]    One object of the present invention is to provide an improvement of ink-pen, comprising a seal-up element. The improvement of ink-pen can effectively protect a pen core, prevent losing a pen cap, reduce the undesired consumption of ink, and extend the lifetime of the ink-pen. 
         [0008]    The present invention provides an improvement of ink-pen, comprising a pen casing, a pen body, a sliding element, a seal-up element and an elastic element so as to be convenient for storage, to reduce ink consumption while in storage, to extend the lifetime. In addition, the improvement of ink-pen prevents cloths from getting stains when the pen cap is accidentally removed so that the user can carry the ink-pen according to the present invention comfortably without fear. Furthermore, in order to improve the writing stability of the improvement of ink-pen according to the invention, the improvement of ink-pen further comprises a plurality of positioning parts to secure the position of the seal-up element and to stabilize the pen body. Besides, in order to further increase the sealing ability to the pen core, the improvement of ink-pen further comprises a plurality of pressurizing elements for increasing the sealing pressure of said seal-up element so as to reinforce the protection to the pen core, reduce the undesired ink consumption, and thereby to extend the lifetime of the ink-pen. The improvement of ink-pen further comprises a pen clip for ease of carrying.

The pen clip  394  is connected with the pen casing  300  for ease of carrying. The elastic element can be a spring, rubber, sponge or other elastic substance. The seal-up element can be rubber, sponge or any substance with sealing functionality. 
         [0028]    According to the fourth embodiment of the present invention, as shown in  FIG. 4 , when the sliding element  400  slides in the second opening  420  and thereupon pushes the pen body  440  to thereby compress the elastic element  460 , an elastic force is generated and thus the pen core  442  pushes the second engaging part  480  to open the second engaging part  480  so as to let the pen core  442  extend beyond the first opening  422  for writing. When the sliding element  400  retracts from the second opening  420 , the elastic force pushes the pen body  440  so that the pen core  442  retracts back into the cavity  484  of the seal-up element  482  for ease of storage, reducing the undesired ink consumption, extending the lifetime of the improvement of ink-pen according to the invention. In addition, the improvement of ink-pen prevents cloths from getting stains when the pen cap is accidentally removed so that the user can carry the ink-pen according to the present invention comfortably without fear. 
         [0029]    Obviously many modifications and variations are possible in light of the above teachings. It is therefore to be understood that within the scope of the appended claims the present invention can be practiced otherwise than as specifically described herein. Although specific embodiments have been illustrated and described herein, it is obvious to those who are skilled in the art that many modifications of the present invention may be made without departing from what is intended to be limited solely by the appended claims.
