Abstract:
1. A slide pen comprising: a pen core having a nib; a tubular pen core slider within which the pen core is housed along a majority of a longitudinal edge of the pen core, the slider having an open lower end, a pen core coupler at an upper inner portion of the slider, and guide ridges formed at an upper outer portion thereof, so as to allow the nib of the pen core to protrude through the lower end thereof and to allow the pen core to be held and coupled therein; a body casing having a tubular upper portion formed with a guide slot to allow the guide ridges of the pen core slider to vertically move and be fixed, a tubular intermediate portion being partially open such that the pen core slider is held inside to allow an outer circumference of the pen core slider to be exposed outside, and a conical lower portion having an open lower end so as to allow the nib of the pen core to move in and out; and a sheath that encloses the outer circumference of the pen core slider and extends along a longitudinal length of the slider, the sheath is exposed to the open intermediate portion of the body casing when the pen core slider is held in the body casing and is formed beneath the guide ridges of the slider and thereby beneath the guide slot of the body casing when held in the body casing, wherein, when the guide ridges of the pen core slider vertically move in the guide slot of the upper portion of the body casing, the pen core slider slides in the body casing, and the nib of the pen core coupled to the pen core coupler of the pen core slider moves in and out through the lower end of the body casing.
