Description
FIELD OF THE INVENTION
[0001] The present invention relates to a brush for cleaning of
teeth within the mouth.
BACKGROUND OF THE INVENTION
[0002] A toothbrush in daily use is usually stored on a
predetermined position in the storage cabinet of a washing
stand.
[0003] However, there is a problem that when the toothbrush after
use is stored, the adhered water of the toothbrush drips in the
storage cabinet, where the water collects and results in unsanitary
surroundings.
[0004] Accordingly, the object of the present invention is to
provide a toothbrush that is not particular about a storage
position and that is good in draining of the water.
SUMMARY OF THE INVENTION
[0005] The foregoing object is accomplished in a toothbrush of
claim 1 of the present invention, which comprises a head, a neck
and a handle continuously formed in turn, wherein the handle is
provided with a sucker portion.
[0006] According to claim 1, the toothbrush can be retained through
the sucker portion on a desired position in the washing stand or
the washbasin. That is, this toothbrush is not particular about a
storing place and needs not a shelf or a cup for storing itself.
Besides, this toothbrush can be retained on every place by just
pushing the sucker portion, so that it can be handled easily.
Further, it is possible to drain the toothbrush well and to keep it
clean as it is retained.
[0007] In a toothbrush of claim 2 of the present invention, the
sucker is coaxially formed on the tip end of the handle opposite to
the head, and the end of the sucker portion is formed to be open as
a bell mouth.
[0008] According to claim 2, the sucker portion is disposed on the
opposite side of the handle to the head with bristles, so that a
user can store the toothbrush well without touching the head with
his hand. Namely, the user may only push the sucker to a part of a
washing stand to stick it there.
[0009] Further, in a toothbrush of claim 3 of the present
invention, the handle is provided integrally with an elastic
material portion and the sucker portion is made of the same
material as the elastic material portion and formed continuously
with it.
[0010] According to claim 3, the sucker portion can be made of a
soft material different from the head, neck and handle, which are
made of hard materials, and well integrated with the handle.
Further, the toothbrush can be enhanced in the property of its
design.
[0011] Other advantageous features of the invention will be obvious
after a reading of the following detailed description of the
preferred embodiment shown in the drawings as follows.
BRIEF DESCRIPTION OF THE DRAWINGS

[0014] FIG. 3 is a rear view of the toothbrush in FIG. 1;
[0015] FIG. 4 is a perspective view of the toothbrush in FIG. 1,
horizontally retained through a sucker portion;
[0016] FIG. 5 is a side view of a toothbrush, as a second
embodiment according to the present invention;
[0017] FIG. 6 is a front view of the toothbrush in FIG. 5; and
[0018] FIG. 7 is a rear view of the toothbrush in FIG. 5.
DESCRIPTION OF THE PREFERRED EMBODIMENT
[0019] Hereinafter, an embodiment of the present invention will be
described with reference to the drawings.
[0020] FIG. 1 to 4 of the drawings illustrates the first embodiment
of the present invention. Referring now to FIG. 1 to 3, a
toothbrush 1 is composed of a head 2, neck 3 and handle 4
continuously formed in turn. On the lower end of the handle 4 is
formed a sucker portion 5. The head 2, neck 3 and handle 4 are made
of hard materials.
[0021] The slightly forward-bent head 2 is provided with bristles
6. The neck 3 is gradually bent forward from the lower end of the
head 2 to be formed slanting downward. The handle 4 is formed
increasing its diameter so as to draw the curved contours of its
longitudinal cross section, the lower portion of which is formed
gradually reducing its diameter to reach to the sucker portion 5.
On the tip end of the handle 4 is coaxially formed the sucker
portion 5, the end of which is open as a bell mouth. On the rear
surface of the handle 4 is integrally stuck an elastic material
portion 8. The sucker portion 5 is made of the same soft material,
rubber, for example, as the elastic material portion 8 and formed
continuously with it.
[0022] The elastic material portion 8 is provided with four cleats
8a, 8a, 8a, 8a for preventing slipping at regular intervals
axially, which are projected from the rear surface of the portion 8
extending laterally. When holding the handle 4, four fingers except
the thumb are capable of well preventing slipping on the elastic
material portion 8 due to those cleats 8a, 8a, 8a, 8a.
[0023] On the surface of the handle 4 opposite to the elastic
material portion 8 and adjacent to the neck 3 is provided a thumb
pad portion 7 in the shape of an ellipse with the long axis
parallel to the handle axis. To this thumb pad portion 7 is stuck a
member having a plurality of soft pleats 7a, 7a, 7a at regular
intervals axially. When laying the thumb on the tips of those
pleats, the pleats 7a, 7a, 7a are deformed respectively, so that it
is possible to lay the thumb on the thumb pad portion 7 with a soft
touch.
[0024] Since the sucker portion 5, thumb pad portion 7 and elastic
material portion 8 are made of elastic materials, it is possible to
enhance the property of a general design of the toothbrush 1 by
making the sucker portion 5, thumb pad portion 7 and elastic
material portion 8 in a color different from that of the head 2,
neck 3 and handle 4.
[0025] Since the toothbrush 1 of the present embodiment is provided
with the sucker portion 5 on the tip end of the handle 4, it
becomes possible to push the sucker portion 5 to a wall surface or
the like to retain the toothbrush 1 in a horizontal condition as
shown in FIG. 4, for example.
[0026] Referring to FIG. 4, there is shown a washing stand 10, on
the lower portion of which is provided a washbasin 11. On the upper
portion of the washbasin 11 is provided a faucet 12. Standing from
the washbasin 11, there is vertically provided a cabinet board 13
constructing the washing stand 10. To the cabinet board 13 is
attached a storage cabinet 14, on the front surface of which is
provided a mirror 15.
[0027] It becomes possible to push the sucker portion 5 to the
cabinet board 13 above the washbasin 11, for example, of the
washing stand 10 to retain the toothbrush 1 in a horizontal
condition. Since the bristles 6 of the toothbrush 1 can be retained
above the washbasin 11, the adhered water of the bristles 6 drips
well into the washbasin 11 in a sanitary condition. Besides, the
bristles 6 of the toothbrush 1 can be well dried to be kept
clean.
[0028] Also, the toothbrush 1 can be retained in a horizontal
condition through the sucker portion 5 on the front surface of the
mirror 15. Further, the toothbrush 1 can be retained and stored in
a vertical condition on a corner of the washbasin 11 through the
sucker portion 5 stuck to the upper surface of the washbasin 11. In
short, the toothbrush 1 is not particular about the storage
position and needs not a shelf or a cup for storing itself. This
toothbrush 1 can be well stored through the sucker portion 5 to be
stuck to a desired place of a washing stand. Besides, the
toothbrush 1 is good in draining of the water to be kept clean.
[0029] Next, a toothbrush 1 as another embodiment is shown in FIG.
5 to 7. In this embodiment, a thumb pad portion 7 is provided with
pleats 7a, 7a, 7a arranged axially and surrounding the whole
periphery thereof like threads of a male screw. The upper end of
the elastic material portion 8 is disposed adjacent to this thumb
pad portion 7. Besides, the elastic material portion 8 is provided
continuously with a front portion 8b arranged in the front side of
the handle 4 as shown in FIGS. 5 and 6.
[0030] In this embodiment, since a sucker portion 5 is also formed
on the tip end of the handle 4, it becomes possible to push the
sucker portion 5 to a wall surface or the like to retain the
toothbrush 1 in a horizontal condition.
