  • TOOTHBRUSH BRISTLES HAVING TIP WITH DOUBLE STRUCTURE AND TOOTHBRUSH COMPRISING SAME
    Publication number: 20150150366
    Abstract: The present invention provides a toothbrush bristle comprising: a core area including a rubber elastic body; and a clad area which is formed around the circumference of the core area, and which includes a resin that is harder than the rubber elastic body, wherein a tip from which the core area is exposed is formed in an end portion thereof. Thus, since the tip is formed in the end portion which comes in contact with the gum such that the rubber elastic body is exposed therefrom, the invention provides the advantage of softly massaging the gums while brushing the teeth.
