Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] The present invention relates to a brush for dental care
and, more particularly, to an interdental brush to clearing food
dregs between a user's teeth.
[0003] 2. Description of the Related Art
[0004] A conventional interdental brush 30 in accordance with the
prior art shown in FIGS. 8 and 9 comprises a handle 35, an elongate
bar 31 mounted on a first end of the handle 35 and having a surface
provided with a plurality of bristles 32 and a pointed shank 33
mounted on a second end of the handle 35 and having a surface
provided with a plurality of serrated portions 34. When the
elongate bar 31 is inserted into a gap between any two teeth of a
user, the bristles 32 can be moved in the gap reciprocally to clear
the gap so as to clean the user's teeth. However, the bristles 32
cannot exactly catch and carry away the residuals left in the gap
between the user's teeth during the reciprocal movement of the
elongate bar 31, thereby decreasing the cleaning effect.

DETAILED DESCRIPTION OF THE INVENTION
[0029] Referring to the drawings and initially to FIGS. 1-3, an
interdental brush 10 in accordance with the preferred embodiment of
the present invention comprises a handle 11, an elongate bar 14
mounted on a first end of the handle 11 and a pointed shank 12
mounted on a second end of the handle 11. The interdental brush 10
is integrally formed by a soft plastic material. The pointed shank
12 has a reduced size and has a surface provided with a plurality
of serrated portions 13. The elongate bar 14 has a free end
provided with a circular head 140. The elongate bar 14 has a
peripheral wall provided with a plurality of flanges 18 each having
an annular shape.
[0030] The elongate bar 14 has a surface provided with a plurality
of bristles 15. The bristles 15 are parallel with each other and
are perpendicular to the elongate bar 14. The bristles 15 are
arranged in pairs and each pair of bristles 15 extend outwardly
from two opposite sides of the elongate bar 14. The bristles 15
have different lengths, and the lengths of the bristles 15 are
reduced gradually from a middle position of the elongate bar 14
toward two opposite ends of the elongate bar 14. Each of the
bristles 15 has a free end provided with an intersection 16 which
divides the free end of each of the bristles 15 to form a
protrusion 17 which protrudes outwardly from the intersection 16.
The intersection 16 of each of the bristles 15 is located between
the protrusion 17 and each of the bristles 15. Preferably, the
intersection 16 of each of the bristles 15 is perpendicular to each
of the bristles 15, and the protrusion 17 of each of the bristles
15 is perpendicular to the intersection 16 and is in line with each
of the bristles 15.
[0031] In use, referring to FIG. 4 with reference to FIGS. 1-3,
when the elongate bar 14 is inserted into a gap 20 between any two
teeth 22 of a user, the bristles 15 can be moved in the gap 20
reciprocally to clean the gap 20 between the user's teeth. At this
time, the intersection 16 of each of the bristles 15 can expand the
clearing extent during the reciprocal movement of the elongate bar
14 to catch and carry away residuals, such as food dregs, particles
and the like, left in the gap 20 so as to clean the user's teeth
exactly and completely. In addition, the circular head 140 of the
elongate bar 14 and the protrusion 17 and each of the bristles 15
can guide movement of the elongate bar 14 smoothly to prevent the
elongate bar 14 and the bristles 15 from injuring the user's teeth
during the clearing process. In addition, the flanges 18 can also
scrape and carry away the residuals left in the gap 20 so as to
clean the roots of the user's teeth exactly. Alternatively, when
the pointed shank 12 is inserted into the gap 20, the serrated
portions 13 can be moved in the gap 20 reciprocally to clean the
gap 20 between the user's teeth.
[0032] Referring to FIGS. 5 and 6, the intersection 16a of each of
the bristles 15 has a substantially V-shaped profile and has two
opposite sides each inclined relative to each of the bristles 15
and the protrusion 17.
[0033] Referring to FIG. 7, each of the bristles 15 is provided
with a plurality of intersections 16 which are arranged in a
staggered manner to enhance the cleaning effect and to expand the
clearing extent.
[0034] Accordingly, the intersection 16 of each of the bristles 15
can catch and carry away the residuals left in the gap 20 between
the user's any two teeth 22 during the reciprocal movement of the
elongate bar 14 so as to clean the user's teeth exactly and
completely. In addition, the circular head 140 of the elongate bar
14 and the protrusion 17 and each of the bristles 15 can guide
movement of the elongate bar 14 smoothly to prevent the elongate
bar 14 and the bristles 15 from injuring the user's teeth during
the clearing process. Further, the flanges 18 can also scrape and
carry away the residuals left in the gap 20 so as to clean the
roots of the user's teeth exactly.
[0035] Although the invention has been explained in relation to its
preferred embodiment(s) as mentioned above, it is to be understood
that many other possible modifications and variations can be made
without departing from the scope of the present invention. It is,
therefore, contemplated that the appended claim or claims will
cover such modifications and variations that fall within the true
scope of the invention.
