Abstract

An improved toothbrush includes a head, which has a surface on which multiple bristles are mounted. The head has an end on which a shank is formed. The shank has a lower end on which a first coupling member is formed. A handle has upper and lower ends, which are respectively formed with a second coupling member and an opening. The second coupling member is engageable with and coupleable with the first coupling member. The handle has a first receiving chamber formed therein and in communication with the opening. A first lid is detachably mounted to and covers the opening. The handle includes a press-down section formed in each of a front end portion and area end portion thereof, such that the press-down sections correspond to the first receiving chamber.

I claim: 
     
         1 . A toothbrush, comprising:
 a head, which has a surface on which multiple bristles are mounted, the head having an end on which a shank is formed, the shank having a lower end on which a first coupling member is formed; and   a handle, which has upper and lower ends, which are respectively formed with a second coupling member and an opening, the second coupling member being engageable with and coupleable with the first coupling member, the handle comprising a first receiving chamber formed therein and in communication with the opening, a first lid being detachably mounted to and covering the opening, the handle comprising a press-down section formed in at least one of a front end portion and area end portion thereof, such that the press-down section corresponds to the first receiving chamber.   
     
     
         2 . The toothbrush according to  claim 1 , wherein the handle has rigidity that is greater than rigidity of the press-down sections and the press-down sections are made of a flexible material. 
     
     
         3 . The toothbrush according to  claim 2 , wherein the handle comprises a recess and a second lid, the second lid being light transmittable and being detachably coupled to and covering the recess, the recess being located above one of the press-down sections. 
     
     
         4 . The toothbrush according to  claim 1 , wherein the handle comprises a recess and a second lid, the second lid being light transmittable and being detachably coupled to and covering the recess. 
     
     
         5 . The toothbrush according to  claim 1 , wherein the first coupling member and the second coupling member respectively comprise a pin and an insertion hole.
