10-2013-0124649 filed Oct. 18, 2013.
FIELD AND BACKGROUND OF THE INVENTION
[0002] The present invention relates, in general, to a nail polish
bottle intended to contain nail polish liquid therein, and, more
particularly, to a nail polish bottle having a pressure opening and
closing valve.
DESCRIPTION OF THE RELATED ART
[0003] Korean Patent Laid-Open Publication No. 10-2002-0021579
(published on Mar. 21, 2002) disclosed an "Automatic Nail Polish
Bottle". The automatic nail polish bottle includes a cap, a body, a
tube, a covering member, a brush support plate, a brush, a button,
and a spring. Internal threads are formed in the cap. External
threads are formed on the body to allow the body to be fastened to
the cap. The tube is provided in the body to contain nail polish
liquid therein. The covering member is movably provided on an upper
portion of the body to cover the tube. The brush support plate is
screwed to an inlet of the tube and has a hole to permit the
passage of the nail polish liquid. The brush is provided on the
brush support plate. The button is provided on an outer surface of
the body to press the tube. The spring is provided at a
predetermined position on an inner surface of the body to restore
the button to its original state.
[0004] However, the automatic nail polish bottle is problematic in
that, when one desires to use the bottle, the covering member
should be pushed in an opening direction, and, after the bottle has
been used, a user should push the covering member in a closing
direction, so that it is inconvenient to use, and, unless the
covering member is closed after the use, the nail polish liquid may
unexpectedly leak from the body.
[0005] The foregoing is intended merely to aid in the understanding
of the background of the present invention, and is not intended to
mean that the present invention falls within the purview of the
related art that is already known to those skilled in the art.
[0006] There is a compelling need for a nail polish bottle that
prevents leakage of the nail polish and is convenient to use and
overcomes the drawbacks of the prior art.
SUMMARY OF THE INVENTION
[0007] One aspect of the present invention is a nail polish bottle,
comprising a bottle body; a cap including a disc portion having a
center hole and a plurality of air holes formed in the disc
portion, the cap having a discharge passage disposed above the
center hole and external-air introduction grooves in flow contact
with the air holes of the disc portion; and a pressure opening and
closing valve mounted to the disc portion such that a skirt portion
of the valve sits below the disc portion and such that a top of the
valve is above the disc portion, when internal pressure in the
bottle body is increased by squeezing the bottle, the skirt portion
presses against the disc portion to close the air holes and the top
of the valve opens allowing nail polish to flow through the
discharge passage if the bottle is upside-down, and when the
internal pressure is restored by releasing a squeezing force, the
skirt portion moves away from the disc to open the air holes and
the top of the valve closes to block polish from escaping through
the discharge passage.
[0008] The bottle may further include a structure wherein the top
of the valve comprises a pair of pieces that either contact each
other to close or else move away from each other to open, depending
upon the internal pressure of the bottle body. The pieces may be
rectangular pieces. The pair of pieces may contact each other to
keep an upper end of a hollow portion of the valve closed until
pressure is exerted through the hollow portion. The upper end of
the hollow portion of the valve may be above the center hole of the
disc portion. The hollow portion of the valve may be inward of a
cylindrical portion of the valve. The external air-introduction
grooves may have a small enough clearance such that a viscous nail
polish in the bottle does not leak out of the bottle through the
air holes and grooves even when the bottle is upside down before
the bottle is squeezed. It may be the case that when internal
pressure in the bottle body. is increased by squeezing the bottle,
the skirt portion may. press against the disc portion as a result
of radially distal ends of the skirt portion flex toward the disc
portion.
[0009] A further aspect of the present invention may comprise a
nail polish bottle, comprising a bottle body; a cylindrical cap
fastened to the bottle body, and including a disc portion in the
cap, with a center hole and a plurality of air holes. formed in the
disc portion; a pressure opening and closing valve mounted to the
disc portion, a top of the valve above the center hole opening or
closing depending on internal pressure of the bottle body, the
valve also opening or closing the air holes of the disc portion
depending on internal pressure of the bottle body; an inner cap
member mounted to the cap, with a discharge passage disposed above
the center hole; and an outer cap member mounted to the cap, with
at least one external-air introduction groove that is formed on the
outer cap member and that is in flow contact with at least one air
hole of the disc portion.
[0010] This aspect of the present invention may also be structured
so that upon squeezing the bottle body when the bottle is
upside-down, a skirt portion of the valve presses again a lower
surface of the disc portion so as to block the air holes of the
disc portion, while internal pressure forces a gap between pieces
of a top of the valve, thereby allowing nail polish to flow through
the gap out of the bottle. In some versions, the pieces of the top
of the valve comprise a pair of rectangular pieces that may be
integrally joined to a top of a cylindrical portion of the valve.
In some versions, the rectangular pieces may come into contact with
each other to keep an upper end of a hollow portion defined by the
cylindrical portion of the valve closed, and, if pressure is
exerted through the hollow portion, the rectangular pieces may move
away from each other. In certain versions, restoring internal
pressure in the bottle as before the bottle was squeezed may close
the gap so as to block further flow of nail polish out of the
bottle through said gap and may restore the skirt portion to a
position away from the disc portion thereby allowing external-air
to enter the bottle body through the at least one external-air
introduction groove. In some versions, an enlarged groove is formed
in the inner cap member and wherein the inner cap member is covered
by the outer cap member, the outer cap member coming into contact
with an inner circumference of an upper end of the cap.
[0011] There may be versions structured such that the cylindrical
cap is fastened to a bottleneck portion of the bottle body, and
wherein a helical fastening portion is formed on the bottleneck
portion.
[0012] The cap may comprise an upper cylindrical portion and a
lower cylindrical portion, the upper cylindrical portion integrally
formed on an upper end of the lower cylindrical portion in a
stepped configuration.
[0013] In some versions, a helical fastening portion is formed on
an inner circumference of the lower cylindrical portion, a stopper
protrusion is formed above the helical fastening portion, and the
disc portion is formed above the stopper protrusion. In some
versions, a locking protrusion is formed on an upper end of an
inner circumference of the upper cylindrical portion.
[0014] A skirt portion of the valve may be provided on a lower end
of a cylindrical portion. The skirt portion may flex toward the air
holes and may block the air holes of the disc portion when internal
pressure is increased in the bottle body.
[0015] In some versions, a pair of rectangular pieces is integrally
provided on a top of the cylindrical portion, the rectangular
pieces coming into contact with each other to keep an upper end of
the hollow portion closed unless increased internal pressure from
the bottle body is exerted through the hollow portion.
[0016] In some versions of the present invention, the inner cap
member comprises a body having a truncated cone shape, and a
cylindrical portion is integrally formed on an upper end of the
body in such a way as to extend upwards therefrom, and an enlarged
groove is defined in the body, and a discharge passage extends from
an upper end of the enlarged groove in such a way as to pass
through the cylindrical portion, and a pocket is formed in an upper
portion of the body so as to accommodate a brush therein, and the
cylindrical portion is disposed in the brush, with the discharge
passage defined in the cylindrical portion.
[0017] In some versions, the outer cap member comprises a
cylindrical portion, with an elliptical hollow portion formed in
the cylindrical portion, and an extended inclined portion is
integrally formed on a lower end of the cylindrical portion, and an
enlarged cylindrical portion is provided on a lower end of the
extended inclined portion, and an enlarged inclined hole is formed

inclined portion in such a way as to extend downwards therefrom,
and an inner inclined surface is formed around the enlarged
inclined hole, and a plurality of external-air introduction grooves
is formed on the extended inclined portion and an outer
circumference of the enlarged cylindrical portion.
[0018] The present invention is intended to propose a nail polish
bottle, in which a pressure opening and closing valve is mounted to
an outlet of a bottle body, so that, if a bottle body made of
flexible material, such as a synthetic resin material, is pushed,
the internal pressure of the bottle body is increased and thus the
pressure opening and closing valve is opened, thereby discharging
nail polish liquid from an interior of the bottle body to a brush
and, if force is eliminated from the bottle body, the internal
pressure of the bottle body is restored to its original state and
thus the pressure opening and closing valve is closed, thereby
automatically preventing the nail polish liquid from leaking.
[0019] In a further aspect of the present invention, there is
provided a nail polish bottle, including a bottle body; a
cylindrical cap fastened to a bottleneck portion of the bottle
body, and including a disc portion in the cap, with a center hole

DETAILED DESCRIPTION OF THE INVENTION
[0035] The following detailed description is of the best currently
contemplated modes of carrying out the invention. The description
is not to be taken in a limiting sense, but is made merely for the
purpose of illustrating the general principles of the invention,
since the scope of the invention is best defined by the appended
claims.
[0036] Referring to FIGS. 1 to 4, a nail polish bottle according to
the present invention includes a bottle body 10. A cylindrical cap
20 is fastened to a bottleneck portion 11 of the bottle body 10,
and includes a disc portion 23 in the cap 20, with a center hole 21
and a plurality of air holes 22 formed in the disc portion 23. A
pressure opening and closing valve 30 is mounted to the disc
portion 23, and serves to open or close the center hole 21 and the
air hole 22 of the disc portion 23. An inner cap member 40 is
mounted to the cap 20, with a discharge passage 41 and an enlarged
groove 42 formed in the inner cap member 40. An outer cap member 50
is mounted to the cap 20, with a plurality of external-air
introduction grooves 56 formed on the outer cap member 50. Thereby,
the inner cap member 40 is covered by the outer cap member 50 that
comes into contact with an inner circumference of an upper end of
the cap 20, and the enlarged groove 42 of the inner cap member 40
coupled to the discharge passage 41 is disposed above the center
hole 21 of the disc portion 23.
[0037] The bottle body 10 is made of a flexible nylon material by
injection molding, and a side portion of the bottle body 10 is
compressed by external force and then is restored to its original
state, with a helical fastening portion 12 formed on the bottleneck
portion 11.
[0038] Referring to FIG. 5, the cap 20 includes an upper
cylindrical portion 24 and a lower cylindrical portion 25, with the
upper cylindrical portion 24 being integrally formed on an upper
end of the lower cylindrical portion 25 in a stepped configuration.
A helical fastening portion 26 is formed on an inner circumference
of the lower cylindrical portion 25. A stopper protrusion 27 is
formed above the helical fastening portion 26. The disc portion 23
is formed above the stopper protrusion 27, and the center hole 21
and the plurality of air holes 22 are formed in the disc portion
23, with a locking protrusion 29 formed on an upper end of an inner
circumference of the upper cylindrical portion 24.
[0039] Thus, as shown in FIGS. 3 and 4, when the helical fastening
portion 26 of the cap 20 is fastened to the helical fastening
portion 12 formed on the bottleneck portion 11 of the bottle body
10, the upper end of the bottleneck portion 11 is stopped by the
stopper protrusion 27, thus preventing the cap 20 from being
excessively fastened to the bottleneck portion 11 of the bottle
body 10. The nail polish liquid contained in the bottle body 10 is
discharged through the center hole 21 that is formed in the disc
portion 23 of the cap 20, and external air is introduced into the
bottle body 10 through the air holes 22 of the cylindrical portion
23.
[0040] Referring to FIG. 6, the pressure opening and closing valve
30 is made of a silicone material by injection molding. A skirt
portion 33 is provided on a lower end of a cylindrical portion 32
in which a hollow portion 31 is formed. A protruding step 34 is
provided on an upper end of an outer circumference of the
cylindrical portion 32, and a pair of rectangular pieces 35 and 36
is integrally provided on a top of the cylindrical portion 32. The
rectangular pieces 35 and 36 come into contact with each other to
keep an upper end of the hollow portion 31 closed. If pressure is
exerted through the hollow portion 31, the rectangular pieces 35
and 36 move away from each other.
[0041] Hence, as shown in FIG. 4, the cylindrical portion 32 of the
pressure opening and closing valve 30 is placed around the center
hole 21 of the disc portion 23 formed in the cap 20, so that the
skirt portion 33 covers a lower surface of the disc portion 23. The
protruding step 34 is stopped by an upper surface of the disc
portion 23, so that the cylindrical portion 32 of the pressure
opening and closing valve 30 is mounted around the center hole 21
of the disc portion 23, and the skirt portion 33 blocks the air
holes 22 formed in the disc portion 23, from the lower surface of
the disc portion 23, thus preventing the nail polish liquid in the
bottle body 10 from being introduced into the air holes 22. In
contrast, if the internal pressure of the bottle body 10 is
reduced, the skirt portion 33 moves away from the lower surface of
the disc portion 23, so that the air hole 22 is opened.
[0042] Referring to FIG. 7, the inner cap member 40 includes a body
43 having a truncated cone shape. A cylindrical portion 44 is
integrally formed on an upper end of the body 43 in such a way as
to extend upwards therefrom. AR enlarged groove 42 is defined in
the body 43. A discharge passage 41 extends from an upper end of
the enlarged groove 42 in such a way as to pass through the
cylindrical portion 44. A pocket 46 is formed in an upper portion
of the body 43 in such a way as to accommodate a brush 47 therein
and to be around a lower end of the cylindrical portion 44. The
cylindrical portion 44 is disposed in the brush 47, with the
discharge passage 41 defined in the cylindrical portion 44.
[0043] Referring to FIG. 8, the outer cap member 50 includes a
cylindrical portion 51, with an elliptical hollow portion 52 formed
in the cylindrical portion 51. An extended inclined portion 53 is
integrally formed on a lower end of the cylindrical portion 51. An
enlarged cylindrical portion 54 is provided on a lower end of the
extended inclined portion 53. An enlarged inclined hole 55 is
formed in a lower end of the hollow portion 52 corresponding to the
extended inclined portion 53 in such a way as to extend downwards
therefrom. An inner inclined surface 57 is formed around the
enlarged inclined hole 55. A plurality of external-air introduction
grooves 56 is formed on the extended inclined portion 53 and an
outer circumference of the enlarged cylindrical portion 54.
[0044] Thereby, as shown in FIG. 4, the circumference of the upper
end of the extended inclined portion 53 of the outer cap member 50
is locked by the locking protrusion 29 of the cap 20 so as to
prevent unexpected removal. The body 43 of the inner cap member 40
is fitted into the enlarged inclined hole 55 of the outer cap
member 50, so that the body 43 of the inner cap member 40 comes
into close contact with the inner inclined surface 57 of the outer
cap member 50, and thereby the brush of the inner cap member 40 is
exposed to the outside through the hollow portion 52 of the outer
cap member 50.
[0045] An operation of the nail polish bottle according to the
present invention configured as described above will be described
in detail with reference to FIGS. 9 and 10.
[0046] First, as shown in FIG. 9, if the bottle body 10 is pushed
in a direction of arrow 65 in a state in which the nail polish
bottle is turned upside down for the purpose of a manicure, the
rectangular pieces 35 and 36 of the pressure opening and closing
valve 30 are moved away from each other by pressure.
Simultaneously, the nail polish liquid 70 contained in the bottle
body 10 is discharged through a gap between the rectangular pieces
35 and 36 of the pressure opening and closing valve 30, the
enlarged groove 42 and the discharge passage 41 of the inner cap
member 40. The nail polish liquid discharged from the discharge
passage 41 of the inner cap member 40 permeates the brush 47, thus
allowing a user to apply the nail polish liquid.
[0047] In this regard, the skirt portion 33 of the pressure opening
and closing valve 30 blocks the air holes 22 formed in the disc
portion 23, from the lower surface of the disc portion 23, so that
the nail polish liquid of the bottle body 10 is not introduced into
the air holes 22, thus preventing the nail polish liquid from
leaking to the outside through the external-air introduction
grooves 56 of the outer cap member 50.
[0048] Further, as shown in FIG. 10, if a pushing force is removed
from the bottle body 10 after a user finishes using the nail
polish, the bottle body 10 is restored to its original state in the
direction of arrow 66, and the rectangular pieces 35 and 36 of the
pressure opening and closing valve 30 are closed by their own
elastic force (restoring force), thus preventing the nail polish
liquid in the bottle body 10 from leaking to the brush 47.
[0049] As such, according to the present invention, even if the
bottle body 10 is laid down or turned, upside down, the rectangular
pieces 35 and 36 of the pressure opening and closing valve 30 are
closed, thus preventing the nail polish liquid 70 from unexpectedly
leaking from the bottle body 10.
[0050] Further, if the pushing force is eliminated from the bottle
body 10, the bottle body 10 is restored to its original state by
its own elasticity. Here, the skirt portion 33 of the pressure
opening and closing valve 30 moves away from the lower surface of
the disc portion 23, so that the air holes 22 of the disc portion
23 are opened, and thereby air introduced through the external-air
introduction grooves 56 of the outer cap member 50 is fed through
the air holes 22 of the disc portion 23 into the bottle body
10.
[0051] As described above, the present invention provides a nail
polish bottle, which is configured so that, if a bottle body is
pushed, the internal pressure of the bottle body is increased and
thus the pressure opening and closing valve is opened, thereby
discharging nail polish liquid contained in the bottle body through
a discharge passage to a brush and allowing a user to apply to
polish to his or her nails, and, if force is eliminated from the
bottle body, the internal pressure of the bottle body is restored
to its original state and thus the pressure opening and closing
valve is closed, thereby automatically preventing the nail polish
liquid from leaking.
[0052] While the invention has been described with respect to a
limited number of embodiments, it will be appreciated that many
variations, modifications and other applications of the invention
may be made. Therefore, the claimed invention as recited in the
claims that follow is not limited to the embodiments described
herein.
