Abstract
This invention relates to the method of manufacturing a toothbrush adapted to be mounted on an automatic toothbrush power handle, and having as a power source vibratory energy in the ultrasonic range. The manufacturing process includes that of providing a plastic brush having a head portion including a plurality of apertures and positioning a bristle cluster respectively in each aperture; and effecting a flow of the plastic in the head portion into substantially surrounding relationship of the bristles in each aperture therein, such that the plastic solidifies in adhesive relationship to the bristles to transmit the ultrasonic vibratory energy from the brush head portion to the bristles.
Claims25
The method of manufacturing toothbrush adapted to be mounted on an automatic toothbrush power handle having as a power source vibratory energy in the ultrasonic range, comprising the steps of:
- A. providing a plastic brush having a head portion including a plurality of apertures therein;
- B. positioning of bristle cluster respectively in each aperture;
- C. changing the shape of the aperture by effecting a flow of the plastic in said respective aperture into substantially surrounding relationship with the bristles in each aperture therein, whereby the plastic solidifies in adhesive relationship to the bristles to transmit the ultrasonic vibratory energy from the brush head portion to the bristles;
- and
- D. coupling to said brush securing means adapted to be coupled to said power handle.
A method as defined in calim 5, wherein said solvent is applied by immersing said head portion and bristles within said solvent.
The method of manufacturing a toothbrush adapted to be mounted on an automatic toothbrush power handle having as a power source vibratory energy in the ultrasonic range, comprising the steps of:
- A. providing a plastic brush with an integrally formed brush head portion having a plurality of apertures therein,
- B. positioning a bristle cluster respectively in each aperture,
- C. simultaneously inserting a staple in each cluster to the brush head,
- D. elevating the temperature of said brush head,
- E. applying a solvent to said brush head while said brush head is in its elevated temperature, whereby said solvent effects a flow of the plastic material adjacent each bristle cluster within its respective aperture such that the plastic flows and thereafter solidifies in adhesive relationship to the bristles to transmit the ultrasonic vibratory energy from the brush head to the respective bristles,
- F. drying the solvent off of said brush head,
- G. trimming said bristles to a desired length, and
- H. finishing the respective bristle ends.

- C. changing the shape of the aperture by effecting a flow of the plastic in said respective aperture into substantially surrounding relationship with the bristles in each aperture therein, whereby the plastic solidifies in adhesive relationship to the bristles to transmit the ultrasonic vibratory energy from the brush head portion to the bristles;
- and
- D. applying to said head portion vibration absorbent material.
