Toothbrush

Abstract

Proposed is a toothbrush having pairs of bristles configured in a bundle, each of the pair of bristles being composed of a first bristle having a fine end portion and a second bristle having a flat end portion, thereby more efficiently removing food remnants that are stuck between teeth or remain on the surfaces of teeth, and efficiently removing food remnants stuck between teeth and dental braces even when the dental braces are installed on the teeth.

1 . A toothbrush composed of a head and a handle connected to an end of the head, the toothbrush comprising:
 toothbrush bristles configured in a bundle, each of the toothbrush bristles composed of a first bristle having a fine end portion corresponding to space between teeth, and a second bristle provided at an inner side of the first bristle and having a flat end portion corresponding to a surface of tooth, the toothbrush bristles being arranged in multiple columns on a surface of the head.   
     
     
         2 . The toothbrush of  claim 1 , wherein each of the toothbrush bristles is configured by being divided into an outer bristle configured as a pair of a first bristle and a second bristle and embedded in an outer portion of the surface of the head, and an inner bristle configured as a pair of a first bristle and a second bristle and embedded in the head to be arranged at an inner side of the outer bristle. 
     
     
         3 . The toothbrush of  claim 2 , wherein the outer bristle and the inner bristle are configured to have different lengths so as to be arranged to have a V-shaped cross section. 
     
     
         4 . The toothbrush of  claim 1 , further comprising:
 molar bristles embedded in multiple columns in an outer portion of the surface of the head, each of the molar bristles having multiple unit bristles configured in a bundle and inclined downward inward in end portions thereof.   
     
     
         5 . The toothbrush of  claim 4 , wherein the molar bristle is a regular bristle or a fine bristle, and each of the toothbrush bristles is a fine bristle. 
     
     
         6 . The toothbrush of  claim 5 , wherein the molar bristle is configured in the bundle on a corner portion of the surface of the head, and provided in the multiple columns. 
     
     
         7 . The toothbrush of  claim 1 , wherein the first bristle is configured to taper in a direction of an outer end portion thereof. 
     
     
         8 . The toothbrush of  claim 1 , wherein a length of the second bristle having the flat end portion is configured to be shorter than a length of the first bristle. 
     
     
         9 . The toothbrush of  claim 1 , wherein an embossment is provided on each of outer circumferential surfaces of the first bristle and the second bristle. 
     
     
         10 . The toothbrush of  claim 4 , wherein an embossment is provided on an outer circumferential surface of the molar bristle. 
     
     
         11 . The toothbrush of  claim 4 , wherein each of the unit bristles of the molar bristle has a flat end portion provided on an upper end thereof. 
     
     
         12 . The toothbrush of  claim 4 , wherein the bundle of the toothbrush bristles composed of the pair of the first and second bristles and the bundle of the molar bristles are configured in longitudinal directions of the head only in two columns at a middle of the surface of the head.
