Abstract
A writing and underline-drawing implement includes: an elongate hollow body having an open top portion and a closed bottom portion; an elongate core received in the elongate hollow body, the elongate core having the tip portion; a cap having a tip hole partially formed in a top portion thereof, the cap being hollow and having an open bottom portion to partially receive and/or passed through by the elongate core, the cap being configured to at least partially move along a length of the elongate hollow body; and rotatable guide wheels coupled to the cap at an upper portion of the cap, the cap being disposed between the guide wheels.
Claims22
A writing and underline-drawing implement comprising:
- an upper elongate hollow body having an open top portion and a closed bottom portion;
- a lower elongate hollow body coupled to the upper hollow body, the lower elongate hollow body having a first tip hole;
- a primary elongate core received in the lower hollow body, the primary elongate core having a first tip portion;
- a secondary elongate core received in the upper elongate hollow body, the secondary elongate core having the second tip portion, wherein the secondary elongate core has a bottom portion contacting the bottom portion of the upper body;
- a cap having a second tip hole partially formed in a top portion thereof, the cap being hollow and having an open bottom portion to partially receive and/or passed through by the secondary elongate core, the cap being inserted into the top portion of the upper elongate hollow body, the cap being configured to at least partially move along a length of the upper elongate hollow body;
- and
- rotatable guide wheels coupled to the cap at an upper portion of the cap, the cap being disposed between the guide wheels,
- wherein the secondary elongate core is configured such that the second tip portion passes through and beyond the second tip hole out of the cap when the cap is further inserted in the upper elongate hollow body by a predetermined distance, thereby to reach an underline-drawing mode where when the guide wheels contact and run on a paper, the second tip portion draws a straight line on the paper.
A writing and underline-drawing implement comprising:
- an elongate hollow body having an open top portion and a closed bottom portion;
- an elongate core received in the elongate hollow body, the elongate core having the tip portion;
- wherein the elongate core has a bottom portion spaced from the bottom portion of the body;
- a cap having a tip hole partially formed in a top portion thereof, the cap being hollow and having an open bottom portion to partially receive and/or passed through by the elongate core, the cap being inserted into the top portion of the elongate hollow body, the cap being configured to at least partially move along a length of the elongate hollow body;
- and
- rotatable guide wheels coupled to the cap at an upper portion of the cap, the cap being disposed between the guide wheels,
- wherein the elongate core is configured such that the tip portion passes through and beyond the tip hole out of the cap when the cap is further inserted in the elongate hollow body by a predetermined distance, thereby to reach an underline-drawing mode where when the guide wheels contact and run on a paper, the tip portion draws a straight line on the paper.
