ATTACHABLE AND DETACHABLE HEAD FOR A TOOTHBRUSH
BACKGROUND OF THE INVENTION
1. Field of the Invention
[1] 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
121 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.

[14] 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.
1151 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.
[161 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.

1171 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).
[18] Although one stub member 32 is illustrated and described, it should be
understood that any
number of stub members may be provided. Further, the embodiments described
herein representing
only two of many possibilities for an attachable and detachable head for a
toothbrush. Additionally, the
invention has been described in considerable detail in language specific to
