Title: Combination type tape dispenser

Description:
BACKGROUND OF THE INVENTION 
   1. Field of the Invention 
   The present invention relates generally to a tape dispenser, and more particularly to a combination type tape dispenser, which may dispense two sizes of tape rolls. 
   2. Description of the Related Art 
   Conventional tape dispensers only dispense single size of tape roll. Some conventional tape dispensers may dispense various tape rolls by replacing the tape reels. This kind of tape dispenser basically has a constant size so that there will be a small dispenser with a huge tape roll or a huge dispenser with a small tape roll. 
   SUMMARY OF THE INVENTION 
   The primary objective of the present invention is to provide a combination type tape dispenser, which dispenses various sizes of tape rolls. 
   The secondary objective of the present invention is to provide a combination type tape dispenser, which the size of the dispenser will change to match the tape roll. 
   According to the objectives of the present invention, a combination type tape dispenser includes a first member having a cutter and a first tape roll mount, and a second member having a second tape roll mount. The first member and the second member are manipulative to be combined and separated. When the first member and the second member are combined, the first member and the second member form a big tape dispenser to mount a big tape roll on the second tape roll mount and cut a tape of the big tape roll by the cutter. When the first member and the second member are separated, the first member forms a small tape dispenser to mount a small tape roll on the first tape roll mount and cut a tape of the small tape roll by the cutter.

   DETAILED DESCRIPTION OF THE INVENTION 
   As shown in  FIG. 1 , a combination type tape dispenser of the preferred embodiment of the present invention includes a first member  10  and a second member  30 . 
   The first member  10  includes a top portion  12  and two parallel lateral walls  14  on opposite sides of the top portion  12 . The top portion  12  is fixed with a cutter  16  at a front thereof and has a tongue  18  at a rear thereof. The tongue  18  has a mound portion  20  to support user&#39;s palm and a bore  22  to be a second coupling portion of the first member  10 . Each of the lateral walls  14  has a post  24  at an inner side thereof and a first tape roll mount  26  at a rear portion thereof. Each of the first tape roll mounts  26  has a rim at an inner side to hold a tape roll and to form a first coupling portion of the first member  10  as well. 
   The second member  30  has a top portion  32  and two lateral walls  34  also. A button  36  is provided on the top portion  32  to form a second coupling portion of the second member  30 . Each of the lateral walls  34  has a second tape roll mount  38 , which is a two-section curved wall on an inner side thereof, a bore  40  to form a first coupling portion of the second member  30 , and an indentation portion  42  around the bore  40  respectively. 
   To dispense a greater tape roll, it has to combine the first member  10  and the second member  30  first. As shown in  FIG. 2 , user has to engage the first tape roll mounts  26  of the first member  10  with the bores  40  of the second member  30  respectively (engagement of the first coupling portions). The first tape roll mount  26  of the first member  10  are received in the indentation portions  42  of the second member  30  respectively that the lateral walls  14 ,  34  of the first member  10  and the second member  30  will be even when the first member  10  and the second member  30  are combined. The first member  10  and the second member  30  may be rotated with the first tape roll mounts  26  and the bores  40  to be a center of rotation. Next, rotating the first member  10  or the second member  30  to have the tongue  18  of the first member  18  cross the top portion  32  of the second member  30  and the button  36  engaged with the bore  40  (engagement of the second coupling portions) that the first member  10  and the second member  30  are firmly combined together to form a big tape dispenser, as shown in  FIG. 3 . Please referring to  FIG. 4 , and  FIG. 5 , a big tape roll  44  may be mounted on the second tape roll mount  38  of the big tape dispenser, and a tape (not shown) of the tape roll may be drawn out and crossing the posts  24  to be cut by the cutter  16 . 
   To separate the first member  10  and the second member  30 , user only has to press the button  36  for disengage the button  36  and the bore  22  (disengagement of the second coupling portions) that causes the first member  10  and the second member  30  may rotate again, and then press the lateral walls  34  of the second member  30  to disengage first tape roll mounts  26  and the bores  40  that the first member  10  is separated from the second member  30 . 
   In separation condition, the first member  10  becomes a small tape dispenser that a small tape roll  46 , referring to  FIG. 6 , may be mounted on the first tape roll mounts  26  for free rotation, and a tape (not shown) of the tape roll may be drawn out and crossing the posts  24  to be cut by the cutter  16 . 
   The main character of the present invention is that the first member  10  serves a small tape dispenser to dispense a small tape roll, and the combination of the first member  10  and the second member  30  serves a big tape dispenser to dispense a big tape roll that the size of the dispenser will match the tape roll. 
   In addition, a center L 1  of the first tape roll mount  26  is different from a center L 2  of the second tape roll mount  38 . In other words, the big tape dispenser and the small dispenser will have different centers of gravity that provide well operation modes respectively. 
   The description above is a few preferred embodiments of the present invention and the equivalence of the present invention is still in the scope of the claim of the present invention.
