Abstract

The purpose of the present invention is to provide a toothbrush that can be used by an infant and that, when an adult is at the completion stage of brushing the infant's teeth, enables the brush to come into contact with a target tooth of the infant in a fine manner. The toothbrush includes a head part (19) and a handle part (23) and has the following: a handle body (11) that extends in the X direction; a brush part (13) implanted in one surface (19a) of the head part (19); a first slippage prevention part (16) disposed on the other surface (19b) side of the head part (19); and a second slippage prevention part (31) which is disposed at the handle part (23) and with which a finger holding the handle part (23) comes into contact.

Description

technical field [0001] The invention relates to a toothbrush for infants and young children, and for adults to help infants and young children brush their teeth. [0002] This application claims priority based on Patent Application No. 2014-104915 for which it applied in Japan on May 21, 2014, and uses the content here.

Therefore, although infants can experience the feeling of brushing their teeth, when adults help infants to brush their teeth, it is difficult to make the bristles delicately contact the target teeth only through the operation of the handle body. [0004] Babies and toddlers have small teeth and the surrounding gums are prone to injury. Therefore, when an adult helps an infant to brush their teeth, it is desirable to press the finger on the other side of the head opposite to the side provided with the bristle...
