Description
TECHNICAL FIELD
[0001] The present invention relates to a toothpaste discharging
toothbrush, and more particularly, to a toothpaste discharging
toothbrush in which toothpaste is stored in a handgrip portion, and
the toothpaste of the handgrip portion is discharged to toothbrush
bristles only when a user brushes their teeth.
BACKGROUND ART
[0002] In general, a toothbrush is used to brush teeth, and
includes a handle provided with an implantation portion at the
front end thereof and toothbrush bristles implanted in the
implantation portion. A user puts a small amount of toothpaste on
the top of the toothbrush bristles, puts the toothbrush bristles
into their mouth, and brushes their teeth while moving the
toothbrush bristles from side to side and from top to bottom. Since
such a toothbrush is necessarily provided together with the
toothpaste in order to brush the teeth, there is an inconvenience
that the user needs to pack the toothbrush together with the
toothpaste when the user goes out, particularly, when the user goes
on a trip, as well as when the user stays at home. If the user does
not pack the toothpaste, there is a problem that the user needs to
newly purchase the toothpaste.
[0003] In order to solve the problems, the present applicant has
invented Korean Patent Publication No. 10-2012-0039140 (toothpaste
discharging toothbrush). FIGS. 1 to 6 are diagrams disclosed in
Korean Patent Publication No. 10-2012-0039140.
[0004] As shown in FIG. 1 (perspective view) and FIG. 2 (sectional
view), in the related art, a toothpaste storage 212 is provided at
the front end of a hollow handgrip portion 210, a piston 400 is
pushed forward using air in an air compressive room at the rear end
thereof, and the toothpaste is discharged toward a nipple 500
through a transfer path 222. A pumping member 300 is coupled to the
end of the handgrip portion 210, and air is pushed into the air
compressive room.
[0005] Meanwhile, as shown in FIG. 4, the nipple 500 is made of a
flexible material, is hollow inside, and includes a nipple main
body 310 having an open bottom, and an upper plate member 520
provided with a cut portion 511. The toothpaste discharged through
the transfer path 222 causes the nipple 500 to be expanded, and the
toothpaste is discharged through the cut portion 522 of the upper
plate member 520 when the internal pressure of the nipple 500 is
increased.
[0006] However, the cut portion 522 of the nipple 500 of the
related art is opened by even a small internal pressure, and
toothpaste is discharged to the outside. Accordingly, it is
difficult to control the discharging of the toothpaste.
[0007] Ideally, even though the toothpaste is pressed into through
the transfer path 222, the nipple 500 needs to store the toothpaste
as much as possible, and needs to discharge the toothpaste toward
an implantation portion 230 little by little when the cut portion
522 is deviated through the shaking, as shown in (c) and (d) of
FIG. 6, while brushing the teeth. However, in the structure of the
nipple 500 of the related art, there are problems that the
toothpaste is discharged through the cut portion 522 even through
the internal pressure of the nipple 500 is slightly increased and
the toothpaste is discharged through the cut portion 522 even after
the teeth are brushed.
[0008] Therefore, there is a need for the improvement of a
structure capable of allowing the nipple 500 to endure the internal
pressure to the maximum.

[0070] A toothpaste discharging toothbrush 1000 of the present
embodiment includes a hollow handgrip portion 1210; a piston 1400
that is provided in the handgrip portion 1210; a pumping member
1300 that is coupled to the rear of the handgrip portion 1210, and
pushes the piston 1400 forward using a pneumatic pressure; an
extended portion 1220 that is coupled to the front end of the
handgrip portion 1210, and includes a transfer path communicatively
connected to the handgrip portion 1210; an implantation portion
1230 that is coupled to the end of the extended portion 1220, and
is provided with a discharge port 1232 communicatively connected to
the transfer path 1222; toothbrush bristles 1231 that are coupled
to the implantation portion 1230; and a nipple 1500 that is coupled
to the discharge port 1232 (see FIGS. 7 and 8).
[0071] The handgrip portion 1210, the extended portion 1220, and
the implantation portion 1230 may be collectively referred to as a
body portion 1200. The body portion 1200 may be divided into
several portions, or may be formed as a single portion.
[0072] The nipple 1500 includes a nipple body portion 1510 that has
an open bottom, is hollow inside, and is made of a flexible
material; an upper plate member 1520 that is positioned on the top
of the nipple body portion 1510, covers the top of the nipple body
portion 1510, and is made of a flexible material; and a cut portion
1522 formed in the upper plate member 1520 (see FIG. 10).
[0073] The upper plate member 1520 has a structure in which a lower
surface is convex downward. A thickness t1 of the central portion
of the upper plate member 1520 is greater than a thickness t2 of
the peripheral region thereof (see (b) of FIG. 10).
[0074] A protruding rim 1530 is formed in the peripheral region of
an upper surface of the upper plate member 1520.
[0075] A lower wall 1511 of the nipple body portion 1510 is thicker
than an upper wall 1512.
[0076] The handgrip portion 1210 is hollow inside. The handgrip
portion 1210 may be formed through plastic injection.
[0077] A piston 1400 is guided and coupled to the inside of the
handgrip portion 1210. A part of the handgrip portion 1210 which is
positioned on the front side from the piston 1400 serves as a
toothpaste storage 1212, and a part thereof which is positioned on
the rear side serves as an air compressive room 1211. The piston
1400 presses the toothpaste stored in the toothpaste storage 1212,
and thus, the toothpaste is moved toward the front side of the
handgrip portion 1210 (see FIG. 8).
[0078] The pumping member 1300 is coupled to the rear side of the
handgrip portion 1210. Air is pushed into the air compressive room
1211 by using the pumping member 1300, and thus, it is possible to
increase the pneumatic pressure. The piston 1400 is pushed forward
by using the pneumatic pressure.
[0079] The pumping member 1300 includes a housing 1310 coupled to
the handgrip portion 1210, the pumping ball 1320 which is coupled
to the housing 1310 and is made of a flexible material, and a valve
1330 which is coupled to the pumping ball 1320 and is positioned
within the handgrip portion 1210. A pumping hole 1322 is formed in
the pumping ball 1320. When the pumping hole 1322 is blocked and
the pumping ball 1320 is pressed, the internal air of the pumping
ball 1320 is introduced into the air compressive room 1211 through
the valve 1330. The valve 1330 blocks the air from flowing
backward. Accordingly, when the pumping ball 1320 is pressed, the
pneumatic pressure of the air compressive room 1211 is increased,
and the piston 1400 is moved forward (see FIG. 8).
[0080] The extended portion 1220 is coupled to the front end of the
handgrip portion 1210. The transfer path 1222 is formed within the
extended portion 1220, and the transfer path 1222 is
communicatively connected to the inside of the handgrip portion
1210. Accordingly, the toothpaste of the toothpaste storage 1212
can be moved through the transfer path 1222.
[0081] A first protrusion ring 1223 and a second protrusion ring
1224 that is positioned on the outside of the first protrusion ring
1223 are formed on the inside of the extended portion 1220. A third
protrusion ring 1213 and a fourth protrusion ring 1214 that is
positioned in front of the third protrusion ring 1213 are formed at
the front end of the handgrip portion 1210. When the extended
portion 1220 and the handgrip portion 1210 are coupled, the first
protrusion ring 1223 and the fourth protrusion ring 1214 are firmly
coupled, and the second protrusion ring 1224 and the third
protrusion ring 1213 are loosely coupled. Accordingly, the space
between the first protrusion ring 1223 and the fourth protrusion
ring 1214 is filled with the toothpaste, and is sealed due to the
solidification of the toothpaste (see FIG. 8).
[0082] The implantation portion 1230 is coupled to the end of the
extended portion 1220. The discharge port 1232 communicatively
connected to the transfer path 1222 is formed in the implantation
portion 1230. The toothbrush bristles 1231 are implanted in the
implantation portion 1230.
[0083] The nipple 1500 is coupled to the discharge port 1232. The
nipple 1500 includes the nipple body portion 1510 that has an open
bottom, is hollow inside, and is made of a flexible material; the
upper plate member 1520 that is positioned on the top of the nipple
body portion 1510, covers the top of the nipple body portion 1510,
and is made of a flexible material; and the cut portion 1522 formed
in the upper plate member 1520. The upper plate member 1520 has a
structure in which the lower surface is convex downward. The
thickness t1 of the central portion of the upper plate member 1520
is greater than the thickness t2 of the peripheral region thereof
(see FIG. 10).
[0084] The toothpaste reaching the discharge port 1232 is
ultimately supplied to the toothbrush bristles 1231 through the cut
portion 1522 of the nipple 1500. Particularly, the toothpaste is
automatically discharged to the cut portion 1522 when the nipple
1550 is stimulated through the brushing of teeth. This process is
described by referring to FIG. 12. The nipple 1500 is filled with
the toothpaste as usual, as shown in (a) of FIG. 12. In this case,
when air is pushed into the air compressive room 1211 by using the
pumping ball 1320, the piston 1400 is moved forward, and the
toothpaste 1600 is supplied to the nipple 1500. In this case, in
order to easily discharge the toothpaste when a user brushes their
teeth, the nipple 1500 needs to store the toothpaste 1600 as much
as possible without the cut portion 1522 being opened.
[0085] In the nipple of FIG. 4 of the related art, the cut portion
is opened even though the internal pressure of the nipple is
slightly increased, the toothpaste is discharged to the outside.
There is a problem that even though the brushing of the teeth is
ended, the toothpaste is discharged.
[0086] In the nipple 1500 of the present invention, the upper plate
member 1520 has a structure in which the lower surface is convex
downward, as shown in (b) of FIG. 10. The thickness t1 of the
central portion of the upper plate member 1520 is greater than the
thickness t2 of the peripheral region thereof. When the internal
pressure of the nipple 1500 is increased (when the toothpaste is
pushed), the shape shown in (c) of FIG. 10 is achieved. When the
pressure is applied to the lower surface of the upper plate member
1520, the lower surface is flattened. In this case, the length of
the section (straight line) of the flattened lower surface is less
than the length of the lower surface (curved line) when the
pressure is not applied. Accordingly, when the pressure is
increased, the cut portion 1522 of the lower surface 1521 is rather
closed. Meanwhile, the upper surface 1523 of the upper plate member
1520 maintains a straight line when there is no internal pressure,
and is opened by being curved when the internal pressure is
increased.
[0087] Consequently, as the internal pressure becomes higher, the
lower surface 1521 of the upper plate member 1520 closes the cut
portion 1522, and the toothpaste is not discharged to the outside
even at a high internal pressure. The toothpaste that is not
discharged is stored in the nipple body portion 1510 of the nipple
1500, and the nipple body portion 1510 is bulging. Since the nipple
1500 is made of a flexible material such as silicones, the nipple
is used even though the internal pressure is increased to some
extent.
[0088] Meanwhile, when the nipple 1500 is touched through the
brushing of the teeth, the cut portion 1522 is deviated and is
opened, as shown in (c) and (d) of FIG. 12. In this case, a small
amount of toothpaste 1600 is discharged through the opened cut
portion 1522. High-pressure toothpaste 1600 is stored in the nipple
1500. Until the internal pressure of the nipple 1500 is cancelled,
the toothpaste may be continuously discharged by the movement that
stimulates the nipple 1500. According to an experiment, the user
can brush their teeth five times by pumping the pumping ball 1320
once.
[0089] Particularly, since only a small amount of toothpaste is
discharged through the nipple 1500, 2 g of toothpaste is consumed
when the user brushes their teeth once. This amount is an
international recommended allowance, and is helpful in improving
tooth health and saving the toothpaste.
[0090] Meanwhile, the lower wall 1511 of the nipple body portion
1510 is thicker than the upper wall 1512. The lower wall 1511 is
coupled to the discharge port 1232, and the discharge port 1232 has
a short pipe shape. The lower wall 1511 of the nipple body portion
1510 is coupled while covering the outer periphery of the discharge
port 1232. When the pressure of the toothpaste is transferred to
the nipple 1500, the upper wall 1512 is thin and is expanded.
However, it is preferable that the lower wall 1511 is not expanded
in order to be coupled to the discharge port 1232 (see FIG.
10).
[0091] The protruding rim 1530 is formed in the peripheral region
