Title: Card type paper toothbrush

Description:
FIELD OF THE INVENTION 
     The present invention relates to a card type paper toothbrush, and especially to a toothbrush which is formed by bending and assembled from a paper plate. Therefore, the cost can be reduced greatly without problem about environment pollution and can be carried conveniently. 
     BACKGROUND OF THE INVENTION 
     Disposable toothbrushes are frequently used in hotels and other public places. Since it is disposable, no health problem is necessary to be considered. However, the general used disposable toothbrush is made of plastics with a larger molding cost and a cost in material so that the whole manufacturing cost is increased. Therefore, the cost of the disposable toothbrush can not be reduced effectively. Moreover, the toothbrush made of plastics is difficult to be decomposed in nature environment so as to induce the problem in environment pollution. Therefore, it is apparent that the general used disposable toothbrush has some defect being necessary to be improved. 
     SUMMARY OF THE INVENTION 
     Accordingly, the primary object of the present invention is to provide a card type paper toothbrush which is disposable, and can be thrown away after it is used once. No trouble in health occurs. The present invention is made of a paper plate with a lower molding cost, further, the cost of paper is low. Therefore, the manufacturing cost is reduced greatly. Since the disposable toothbrush is only used once, no waste occurs. Furthermore, since the paper can be decomposed in a natural environment, no problem of environment pollution occurs. And, before assembling, the present invention is a thin plate and thus only occupies a smaller space, so that it is easily portable. 
     The various objects and advantages of the present invention will be more readily understood from the following detailed description when read in conjunction with the appended drawing.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     With reference to FIG. 1, an exploded view of the present invention is illustrated. The object of the present invention is to provide a card type paper toothbrush. At first, a paper is cut to be formed as a plane as that shown in FIG. 1, and then it is further bent to be formed as a cubic shape shown in FIG.  11 . Thus, the card type paper toothbrush of the present invention is formed. 
     As shown in FIG. 1, the card type paper toothbrush of the present invention includes an approximately oblong plate  10 . the plate  10  is installed with a plurality of parallel handle fold lines  11 ,  12 ,  13 , and  14 , seat fold lines  15 ,  16  and  17 , and brush hair fold lines  18 ,  19  and  20 . The handle fold lines  11 ,  12 ,  13 , and  14  serve to be formed with a first lateral plate  21 , a second lateral plate  22 , a third lateral plate  23 , a fourth lateral plate  24  and a fifth lateral plate  25 . A first protruding plate  26  and a second protruding plate  27  are formed between the seat fold lines  15 ,  16  and  17 . A first brush hair portion  28 , a second brush hair portion  29 , a third brush hair portion  30  and a fourth brush hair portion  31  are formed between the brush hair fold lines  18 ,  19  and  20 . the brush hair portions  28 ,  29 ,  30  and  31  are formed with a plurality of brush hair cut lines  32  so as to cut the brush hair portion into a plurality of brush hairs  33 . A tear-able tooth wire  34  is formed in the brush hair portions  28 ,  29 ,  30  and  31 . The tooth wire  34  penetrates through the brush hair portions  28 ,  29 ,  30  and  31 . One end of the tooth wire  34  protrudes out of the plate  10 , and a further first cut line  36  is installed on the plate  10 . the first cut line  36  is placed between the fifth lateral plate  25  and the first brush hair portion  28  and is connected to the seat fold line  15 . One end of the first cut line  36  is connected to the second cut line  37 . The second cut line  37  is vertical to the first cut line  36 . Other than the brush hair portions  28 ,  29 ,  30  and  31  and the right side of the second cut line  37 , the plate  10  is coated with a proper sticky surface  35 . 
     With reference to FIGS. 2 and 10, a schematic view showing the assembly of the present invention is illustrated. At first, the first cut line  36  an the second cut line  37  of the plate  10  are torn away, and then the first lateral plate  21 , second lateral plate  22 , third lateral plate  23 , fourth lateral plate  24  and fifth lateral plate  25  are wound toward the same direction by folding along the fold lines  11 ,  12 ,  13 , and  14  (as shown in FIG.  2 ). The lateral plants  21 ,  22 ,  23  and  24  are bent and wound as a hollow triangular and are fixed by the sticky surface  35 . Then the fifth lateral plate  25  is wound to enclosed thereon to be formed as a handle  38  of the toothbrush (as shown in FIG. 3) for being held by a user. It remains to be fixed by the sticky surface  35 . Then, the brush hair portions  28 ,  29 ,  30 , and  31  are bent as a multiple fold shape (as shown in FIGS.  4  and  5 ), and then are combined together to be formed as a long strip (as shown in FIG.  6 ). Then, the first protruding plate  26  and the second protruding plate  27  are bent by the fold line  16  so that the first protruding plate  26  and the second protruding plate  27  encloses the front end of the handle  38  so as to be formed as a protruded seat  39  (as shown in FIGS.  7  and  8 ). Therefore, the long brush hair portions  28 ,  29 ,  30  and  31  can be wound and fixedly connected to the outer side of the seat  39  (as shown in FIGS. 9 and 10) and can be fixed by the sticky surface  35 . Then, the tooth wire  34  in the brush hair portions  28 ,  29 ,  30  and  31  are torn away, then the brush hairs  33  of the brush hair portions  28 ,  29 ,  30  and  31  are dispersed (as shown in FIG. 11) for being assembly with a complete card type paper toothbrush. Moreover, the tooth wire  34  can be used. 
     The present invention is a disposable toothbrush, which can be thrown away after one use. No trouble in health occurs. The present invention is made of a paper plate with a lower molding cost, further, the cost of paper is low. Therefore, the manufacturing cost is reduced greatly. Since the disposable toothbrush is only used once, no waste occurs. furthermore, the paper can be decomposed in a natural environment, no problem of environment pollution occurs. And, before assembling, the present invention is a thin plate and thus only occupies a smaller space, so that it is easily portable. 
     In summary, by the disposable toothbrush of the present invention, the defects in the present invention, such as high cost, made of plastics, environment pollution, are improved.
