Description

A kind of marking tool

Technical field

The utility model relates to a kind of marking tool, particularly as the color pen, and felt material stylus, fiber nib, ball pen, the marking tool of pen and other types.

Background technology

Marking tool on the existing market; complex forms is changeable; great variety of goods; but adopt the structure of the marking tool of marking fluid can be divided into two big classes: the first kind is that marking fluid is stored in the reservoir; second class is that marking fluid is attracted in the gap that contains the liquid core, and it has been that protection contains liquid core and convenient with the effect of holding pen that what is called contains the outer housing of liquid core.Though this two class formation is that the cross section is different, all have following common shortcoming: the storage of 1. depositing marking fluid very little, thereby the frequency of supplemental markers liquid or change-fountain pen core is very high.2. because of this body structure of marking tool institute extremely, if filling surpasses in the time of itself bearing the capacity of depositing marking fluid to lettering pen, the very easy ink leak water of this pen then, so its anti-performance of leaking is just poor, so the capacity of existing marking tool marking fluid is the structure that belongs to low capacity.3. especially popular a kind of disposable marking tool just be abandoned when also very new because of the structure pen that uses up fast of marking fluid often, thereby the utilization rate of lump-sum is very low, causes the very big wasting of resources.
