  • Patent number: 7699608
    Abstract: An interproximal squirt brush includes a solution container having a compressible solution chamber for containing a washing solution and a nozzle head having an opening, and a brush head including a brush arm and a brush member. The brush arm has a brush portion and a retention portion slidably inserted into the opening of the solution container, wherein a dispensing channel is formed between the retention portion of the brush arm and the inner wall of the nozzle head for allowing the solution to pass therethrough. The brush member is provided at the brush portion of the brush arm. Therefore, when a compression force is applied on the solution container, the solution is released to the brush member through the dispensing channel of the nozzle head.

  • Patent number: 6932603
    Abstract: An interproximal squirt brush includes a squeezable bottle having a solution cavity for containing a washing solution and a nozzle head having an opening, and a brush head including a brush arm and a brush member. The brush arm has a brush portion and a resilient portion slidably inserted into the opening of the squeezable bottle for providing an urging force against an inner wall of the nozzle head, wherein a dispensing channel is formed between the resilient portion of the brush arm and the inner wall of the nozzle head for allowing the washing solution to pass therethrough. The brush member is provided at the brush portion of the brush arm. Therefore, when a squeezing force is applied on the squeezable bottle, the washing solution is released to the brush member through the dispensing channel of the nozzle head.
