Title: Squeeze to write ink highlighter

Description:
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  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.
