BACKGROUND OF THE INVENTION
Ink highlighter has to be recapped after using. If user forgets to recap ink highlighter ink will dry out. If user holds it in hand and does not use it to write for one minute or two ink will dry out on the wick tip and it will be hard to use it to write. The present invented squeeze to write ink highlighter can solve this problems because if user does not squeeze it its cover will close spontaneously.
THE BRIEF DESCRIPTION OF THE INVENTION
Squeeze to write ink highlighter has a device to advance its ink wick tip to open cover for writing when user squeezes it and its ink wick tip will retract to close its cover when user releases squeezing force. Therefore user uses only two fingers to squeeze or to release to control the opening and closure of ink highlighter.

Numeral 15 of FIGS. 1, 2, 3, 4 and 5 is squeeze button that is to be squeezed by finger. Numeral 16 of FIGS. 1, 2, 3, 4 and 5 is window of squeeze button 15. Numeral 17 of FIGS. 3, 4 and 5 is opening at the tip 13 of cover 11. Numeral 18 of FIGS. 3 is pin hole that locates at side wall 19 of cover 11. There are two pin holes on each side of side wall 19. Numeral 20 of FIGS. 1, 3 and 4 is pivot pin. There are two pivot pins. Numeral 21 of FIGS. 2, 3 and 5 is pivot pin hole of squeeze button 15. Numeral 22 of FIGS. 2, 3 and 5 is pusher hole on squeeze button 15. Numeral 23 of FIGS. 2, 3 and 5 is pusher. Pusher 23 is fastened at the pusher hole 22 on squeeze button 15 as illustrated in FIGS. 2 and 5. Numeral 24 of FIGS. 2 and 5 is a cone-shaped chamber that locates inside the rear portion of cover 11 and occupies about three fourths of total length of cover 11. Pivot pin 20 passes through pin hole 18 of one side of side wall 19, pivot pin-hole 21 of squeeze button 15 and comes out side hole 18 of another side of side wall 19 to fasten squeeze button 15 inside the cone-shaped chamber 24 of cover 11 as illustrated in FIGS. 2 and 5. Numeral 25 of FIGS. 2, 3 and 5 is spring coil. Numeral 26 of FIGS. 2, 3, 4 and 5 is wick. Numeral 27 of FIGS. 2, 3 and 5 is wick tip. Numeral 27 of FIGS. 2, 3 and 5 is wick tube. Wick 26 is installed inside wick tube 27 and ink tube 14 as illustrated in FIGS. 2 and 5. Numeral 28 of FIGS. 2, 3 and 5 is circular wing that locates at around the front one third portion of wick tube 27. Numeral 29 of FIGS. 2, 3 and 5 is the tip of wick 26. Pusher 23 rests at circular wing 28 as illustrated in FIGS. 2 and 5. Spring coil 25 encircles the front portion 30 of wick tube 27 and is placed against circular wing 28 as illustrated in FIGS. 2 and 5. Numeral 31 of FIGS. 2 and 5 is canal that locates in the center of the front portion of cover 11 and occupies about one fourth of the total length of cover 11. Canal 31 connects to cone-shaped chamber 24. Numeral 39 of FIGS. 2 and 5 is a circular ridge that locates at the bottom of canal 31 and at the top of cone-shaped chamber 24. Wick tube 27 is inserted through circular ridge 39 into canal 31 from cone-shaped chamber 24. Wick tip 29 and front portion 30 of wick tube 27 move freely forward and backward inside canal 31. Numeral 32 of FIGS. 2, 3 and 5 is sealing ring. Numeral 33 of FIG. 3 is the front end of the front portion 30 of wick tube 27.Sealing ring 32 is fixed at the front end 33 of the front portion 30 of wick tube 27 and rests on circular ridge 39 when squeeze to write ink highlighter is in closure status. Cover-cap 12 seals the opening 17 of cover 11 at above and sealing ring 32 seals the circular ridge 39 at bottom of canal 31 to create an air-tight canal 31 to prevent ink from evaporating when squeeze to write ink highlighter is at closure status. The first step to assemble squeeze to write ink highlighter is to insert spring coil 25 into the front portion 30 of wick tube 27. The second step is to insert wick tube 27 and spring coil 25 into circular ridge 39 and canal 31 through cone-shaped chamber 24. The third step is fasten pusher 23 onto push-hole 22 of squeeze button 15. The fourth step is to inset the unit of connected squeeze button 15 and pusher 23 into cone-shaped chamber 24 through squeeze button window and to place pusher 23 against circular wing 28. The fifth step is to align pivot pin-hole 21 with pin hole 18. The sixth step is to insert pivot pin 20 into pin hole 18 at one side wall 19 and pivot pin-hole 21 to comes out pin hole 18 at another side of side wall 19 to fasten squeeze button 15 inside cone-shaped chamber 24. Then both ends of pivot pin-hole 21 are flattened to secure it on side wall 19 of cover 11 as illustrated in FIGS. 1, 3 and 4. The last step is to fix sealing ring 32 onto front end 33 of the front portion of wick tube. Numeral 83 of FIGS. 2, and 5 is the front portion of ink tube 14. The front portion of ink tube 83 is inserted in the cone-shaped chamber 24 of cover 11 as illustrated in FIGS. 2 and 5. Pivot pin 20 acts as a pivot of squeeze button 15. When user presses downward squeeze button 15 pusher 23 advances to push circular wing 28 forward to push wick tip 29 coming out of opening 17 for writing. Numeral 34 of FIG. 6 is cap-cover that has a built-in cap-ring 35. Numeral 36 of FIG. 6 is cap base-ring that has two built-in ring buttons 37. Numeral 38 of FIG. 6 is cap-pin. Numeral 89 of FIG. 6 is spring wire coil. Cap-pin 38 passes through one ring button 37, spring wire coil 89, cap-ring 35 and another ring button 37 to fasten cap-cover 34 to cap base-ring 36. Numeral 40 of FIG. 3 is rim of opening 17 of cover 11. Cover-cap 12 is fixed to the rim 40 with adhesive or by other methods. Spring wire coil 89 presses cap-cover 34 against cover cap base-ring 36 to close opening 17.
