Description

CROSS-REFERENCE TO RELATED APPLICATIONS

The present application claims priority to U.S. Patent Application Ser. No. 62/764,358, filed on Jul. 31, 2019 entitled “Eco-Responsible Toothbrush”, the disclosure of which is hereby incorporated in its entirety at least by reference.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention generally relates to hygienic implements but more particularly to an attachable and detachable head for a toothbrush.

2. Description of Related Art

It is recommended that a person's toothbrush be replaced every three months, which creates a lot of plastic toothbrushes in our landfills. There are some “eco-brushes” having a handle made out of bamboo and with bristle made out of a biodegradable material but these are small scale operations and don't make much of an impact. Electric toothbrushes have removable heads so that a user can replace the bristle without the need to buy a new electric base. There is still a need for a practical easy to operate head changing system for non-electric toothbrushes.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

The following description is provided to enable any person skilled in the art to make and use the invention and sets forth the best modes contemplated by the inventor of carrying out his invention. Various modifications, however, will remain readily apparent to those skilled in the art, since the general principles of the present invention have been defined herein to specifically provide an attachable and detachable head for a toothbrush.
Referring now to FIGS. 1A-D and FIGS. 2A-B, one embodiment of an attachable and detachable head for a toothbrush is illustrated. In this embodiment, a toothbrush handle 10 includes a tip portion 11 configured to receive a head section 12. In one embodiment, the head section is comprised of a base member 28 and bristles 30. In one embodiment, the bottom portion of the head section (best seen in FIG. 1B), includes at least one bulb member 14 configured to be releasably attached to at least one opening 22 positioned on the tip portion 11 of the toothbrush handle 10. In some embodiments, a pair of bulb members is provided. However, it should be understood that any number of bulb members may be provided. In one embodiment, the at least one bulb member comprises a stem member 16 and a bulbous member 18. In one embodiment, the bulbous member 18 comprises a split sphere 20 forming a “V” shape 23 enabling the bulbous member to reduce in size when pushed through opening 22. More specifically, the split sphere 20 comprised of two hemispheres are configured to clasp together so as to reduce the size of the split sphere 20 as it is pushed an opening 22 of the at least one opening positioned on the tip portion 11 of the handle 10.
When the bulb member, and corresponding split sphere is pushed through opening 22, the split sphere is configured to separate forming the “V” shape 23, wherein the “V” shape is configured and sized to perfectly fit in a beveled seat portions 24 in the opening 22.
In one embodiment, the bulb member 14 further comprises a base portion 26, wherein the base portion is wider than the stem member 16. In one embodiment, the base portion is wedged shaped such that the base portion is configured to fit in a second beveled portion of the opening (not shown). Both bevel portions on both sides of the tip portion ensure that the head section 12 is stable and secure when attached to the handle 10.
Referring now to FIGS. 3A-C and FIGS. 4A-C, an alternate embodiment of an attachable and detachable head for a toothbrush is illustrated. This embodiment is a similar male/female attachment mechanism as the other embodiment previously discussed, however the engagement securement method is different. In this embodiment, the base member 28 of head section 12 comprises a stub member 32. The stub member having an upper section with a pair of tip members 34 extending laterally therefrom. In one embodiment, the stub member 32 is configured and sized to pass through a complementarily shaped opening 22′ positioned on the tip portion of the toothbrush handle. In one embodiment, opening 22′ allows the stub member 32 go through when the head 12 is perpendicularly oriented relative to the longitudinal axis of the handle 10. Once the stub member 32 is engaged with opening 22′, the head section 12 may be twisted 90 degrees such that the pair of tip members 34 lock onto position on the tip portion of the toothbrush handle. To ensure adequate tightening between the base member 28 and the tip portion 11, a pair of ramps 36 forming part of the opening 22′ allows for a progressive tightening as the head is twisted (counterclockwise as per FIG. 4B).
Although one stub member 32 is illustrated and described, it should be understood that any number of stub members may be provided.
