Description
BACKGROUND OF THE INVENTION
[0001] The present invention disclosed herein relates to a liquid
lipstick container, wherein a liquid lipstick container has a
configuration in which an ascending/descending guide member is
rotated together when a user rotates a container body while
gripping a support body, such that a pumping guide member is lifted
up/lowered, thereby performing a pumping operation. Thus, liquid
contents are discharged through a simple structure, which improves
usability when contents are applied through an applicator at an
upper portion of the container.
[0002] Generally, a solid lipstick is configured to lift/lower a
solid stick to the outside of a container by rotating a lower
portion of the container after opening a cover thereof. For
example, when using a lipstick, a user first opens the cover of a
container, protrudes the stick out by rotating a lower portion
thereof, and lowers the stick to be received into the container
after using.
[0003] However, this type of solid lipstick has a problem wherein
its ingredients are easily spoiled by contact with outside air.
[0004] In addition, another type of lipstick, which is used by
spreading a liquid lipstick onto a brush like spreading a nail
polish, also has a problem of hardening easily by contact with
outside air.
[0005] To solve the problems as the above, "liquid lipstick
container" is disclosed in the registered utility model patent no.
20-0367724 (hereafter called as the registered utility model
patent).
[0006] The registered utility model patent relates to a liquid
lipstick container, the liquid lipstick container comprising: a
liquid lipstick receiving tube (10) receiving a liquid lipstick; a
piston (20) pressurizing the liquid lipstick received in the liquid
lipstick receiving tube; a piston rod (30) pushing the piston (20)
and pressurizing a liquid lipstick (M); an operation housing (40)
operating the piston rod (30); a brush supporting cap (50)
supporting a lipstick brush (51); and a cap (20) sealing the
lipstick brush (51),
[0007] wherein the liquid lipstick receiving tube (10) is
characterized to be equipped with a pair of elastic leg parts (11)
having a screw part (13) at an inner side of a lower end thereof
and an outward protrusion (12) at an outer side end thereof,
wherein the piston rod (30) comprises a screw part (32)
screw-coupled to the elastic leg part (11) and an operating
protrusion (33) at a lower end thereof, wherein the operation
housing (40) is characterized to comprise an operating rib (41) at
an interior so as to push the operating protrusion (33).
[0008] The registered utility has a structure wherein as a piston
rod (30) ascends by the rotation of the rotation of an operation
housing (40), a piston (20) coupled with a globular protrusion (31)
at an upper end of a piston rod (30) moves in an upward direction
and discharges liquid contents by squeezing. To squeeze contents
out, the lipstick container should be equipped with an operating
rib (41), an operating protrusion (33), a pair of elastic leg parts
(11); therefore, the structure of the lipstick container becomes
complicated, thereby resulting in a problem a complicated assembly
process and a high manufacturing cost.
[0009] In addition, a space for the length of a piston rod (30)
should be secured; therefore, the lipstick container gets bigger in
size, thereby resulting in a problem of not being easy to
carry.

[0014] Furthermore, it is characterized that a sealing member,
whose outer circumferential surface is contacted to the content
inflow part, and whose inner circumferential surface is contacted
to the content suction tube, is coupled at the content inflow part
and seals a space separated between the content inflow part and the
content suction tube.
[0015] Furthermore, it is characterized that the content suction
tube pressurizes the first check valve in a state of the pumping
guide member descending, and prevents the first check valve from
being opened.
[0016] Furthermore, it is characterized that at an upper portion of
the pumping guide member is coupled a content moving part which
connects the pumping guide member and the applicator such that the
contents flowing into the valve installation part can move to the
applicator.
[0017] Furthermore, it is characterized that at an upper portion of
the pumping guide member is equipped a spring which is disposed

ascending/descending guide protrusion to the bottom dead point
thereof.
[0018] As described above, the present invention has an advantage
wherein a liquid lipstick container has a configuration in which an
ascending/descending guide member is rotated together when a user
rotates a container body while holding a support body, such that a
pumping guide member is lifted/lowered, thereby performing a
pumping operation. Thus, liquid contents are discharged through a
simple structure, which improves usability when contents are
applied through an applicator at an upper portion of the
container.
[0019] Furthermore, it is possible to prevent air inflow into the
inside of the container body by means of a structure of double
check valves, and also possible to store the contents discharged

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS
[0025] Hereinafter, exemplary embodiments of the present invention
will be described in detail with reference to the accompanying
drawings. The same reference numerals provided in the drawings
indicate the same members.
[0026] FIG. 1 is an exploded perspective view illustrating a
configuration of a liquid lipstick container according to an
exemplary embodiment of the present invention. FIG. 2 is an
assembled perspective view illustrating a configuration of a liquid
lipstick container according to an exemplary embodiment of the
present invention. FIG. 3 is a cross-sectional view illustrating a
configuration of a liquid lipstick container according to an
exemplary embodiment of the present invention.
[0027] Referring to FIGS. 1 to 3, a liquid lipstick container
according to an exemplary embodiment of the present invention may
include a container body 100, an ascending/descending guide member
200, a pumping guide member 300, a support body 400, and an
applicator 500.
[0028] The container body 100 storing liquid contents is configured
to have a volume getting reduced according to a use of the
contents, and simply saying, the container body 100 may equip a
piston 110 which ascends according to a use of the contents inside
of the content body 100. Additionally, it is possible that the
container body 100 has a configuration wherein an inner container
made of soft material that is absorbed according to a use of
contents can be coupled separately inside the container body
100.
[0029] In the present invention, it is characterized that the
container body 100 is configured to be rotated in a state that a
support body 400 to be described later is gripped. When a user
rotates the container body 100, a pumping guide member 300 can be
ascended/descended by rotating an ascending/descending guide member
200 together which is coupled at an upper portion of the container
body 100.
[0030] Meanwhile, at an upper portion of the container body 100 is
coupled an over cap 800 which encases the support body 400 and the
applicator 500 so as to prevent the support body 400 and the
applicator 500 from being broken by a foreign material flowing
through a discharging hole 511 or by an external pressure.
[0031] The ascending/descending guide member 200, coupled to an
upper portion of the container body 100 and rotating together when
the container body 100 rotates, is equipped with a content inflow
part 210 forming a content inflow hole 211 at an inner center
portion thereof such that the contents stored in the container body
100 can flow in. At the content inflow part 210 is equipped a first
check valve 212 which is installed at an upper portion of the
content inflow hole 211 and opens/closes the content inflow hole
211 according to a pressure change of the content inflow part
210.
[0032] Furthermore, at the content inflow part 210 is coupled a
sealing member 700 which seals a space separated between the
content inflow part 210 and a content suction tube 320 to be
described later. An outer circumferential surface of the sealing
member 700 is closely contacted to the content inflow part 210 and
an inner circumferential surface thereof is closely contacted to
the content suction tube 320, such that the sealing member 700
seals the space separated between the content inflow part 210 and
the content suction tube 320.
[0033] In the present invention, it is characterized that at an
upper portion of the ascending/descending guide member 200 is
equipped an ascending/descending guide protrusion 220 which
ascends/descends a pumping guide member 300 to be described later
by rotation of the ascending/descending guide member, wherein a
pair of ascending/descending guide protrusions 220 are protrusively
formed alternately above and below along the perimeter of an upper
end of the ascending/descending guide member 200 and guides a
movement of a pumping guide protrusion 310. When the pumping guide
protrusion 310 moves form a bottom dead point 312 of the
ascending/descending guide protrusion 220 to a top dead point 311
thereof, the pumping guide member 300 ascends, whereas when the
pumping guide protrusion 310 moves from a top dead point 311 of the
ascending/descending guide protrusion 220 to a bottom dead point
312 thereof, the pumping guide member 300 descends, thereby
achieving an ascent/descent of the pumping guide member 300.
[0034] Meanwhile, it is possible that the ascending/descending
guide protrusion 220 can be configured in a way that the container
body 100 can be rotated to both directions. However, it is
preferable to be rotated to one direction for operational stability
e.g. not to easily discharge contents by rotating the content body
100 by an external pressure during the period of storing or not to
store contents with a check valve opened. For this purpose, at both
sides of the bottom dead point of the ascending/descending guide
protrusion 220 is formed a protrusion 221 for preventing a reverse
rotation of the container body 100.
[0035] The pumping guide member 300 ascended/descended by the
rotation of the ascending/descending guide member 200 changes an
internal pressure of the content inflow part 210 and induces a
pumping operation, further comprising a pumping guide protrusion
310, a content suction tube 320, and a valve installation part
330.
[0036] A pair of the pumping guide protrusions 310 protrusively
formed at both sides of the pumping guide member 300 are secured at
an upper end of the ascending/descending guide protrusion 220, and
move along an upper side face of the ascending/descending guide
protrusion 220 when ascending/descending guide member rotates. At
this time, the pumping guide protrusion 310 can be inserted to a
vertical guide groove 420 formed at an inner side of the support
body 400 and move vertically.
[0037] The content suction tube 320, which ascends together as the
pumping guide protrusion 310 ascends and sucks the contents stored
in the container body 100 by changing an internal pressure of the
content inflow part 210, has a tube shape with an inner part empty
such that contents can move through.
[0038] The content suction tube 320, which ascends/descends in a
state that an outer circumferential surface thereof is closely
contacted to the sealing member 700 and makes it possible for a
first check valve 212 to open/close a content inflow hole 211 by
changing an internal pressure of the content inflow part 210,
pressurizes an upper end of the first check valve 212 in a state
that the pumping guide member 300 is descended and thereby prevents
the first check valve 212 from being opened.
[0039] The valve installation part 330 forms a space which stores
contents moving to an upper portion thereof through the content
suction tube 320 and has a second check valve 331 installed so as
to open/close an opened upper end of the content suction tube 320,
wherein the second check valve 331 closes the open upper end of the
content suction tube 320 when the pumping guide member 300 ascends,
whereas the second check valve 331 opens an open upper end of the
content suction tube 320 by the pressure of contents when the
pumping guide member 300 descends.
[0040] Meanwhile, at an upper portion of the pumping guide member
300 are installed a content moving part 600 which connects the
pumping guide member 300 and an applicator 500 such that contents
flowing in the valve installation part 330 can move to the
applicator 500. The content moving part 600 comprises a coupling
part 610 which is coupled to an upper portion of the pumping guide
member 300, and a content moving tube 620 which extends from the
coupling part 610 and is coupled to a discharging tube 520 of the
applicator 500 so as to be ascended/descended and forms a space
where contents moves.
[0041] The content moving part 600 equips a hollow such that the
contents flowing into the valve installation part 330 can move to
the applicator 500.
[0042] Furthermore, at an upper portion of the pumping guide member
300 is equipped a spring (S) which is disposed encasing the content
moving part 600 at an outer side of the content moving part 600,
and provides an elastic force to a downward direction during the
process when the pumping guide protrusion 310 moves from a top dead
point 311 of the ascending/descending guide protrusion 220 to a
bottom dead point 312 thereof and causes the pumping guide member
300 to descend. A lower end of the spring (S) is secured to an
upper portion of the pumping guide member 300 while an upper end
thereof is supported by an upper inner side of the support body
400, such that the spring (S) contracts when the pumping guide
protrusion 310 ascends along an upper side face of the
ascending/descending guide protrusion 220, and stretches when the
pumping guide protrusion 310 descends along an upper side surface
of the ascending/descending guide protrusion 220, thereby providing
an elastic force to the pumping guide member 300.
[0043] The support body 400, which is coupled at an upper portion
of the container body 100, encasing the ascending/descending guide
member 200 and the pumping guide member 300, forms a hollow 410 at
an upper portion thereof such that the applicator 500 can be
coupled and a vertical guide groove 420 which guides a vertical
movement of the pumping guide protrusion 310.
[0044] The applicator 500, which is coupled to the hollow 410 of
the support body 400 and applies contents to a user's lips,
comprises an application surface 510, wherein the application
surface 510 has a discharging hole 511 at a center portion thereof
such that contents can be discharged through.
[0045] Furthermore, at an inner upper side of the applicator 500 is
equipped a discharging tube 520 which extends to a downward
direction such that the content moving tube 620 of the content
moving part 600 can be coupled so as to ascend/descend.
[0046] Hereinafter, referring FIGS. 4 to 6, an operational process
of a liquid lipstick container according to an exemplary embodiment
of the present invention will be explained. FIGS. 4 to 6 are views
illustrating an operational state of a liquid lipstick container
according to an exemplary embodiment of the present invention. FIG.
7(a) to FIG. 7(c) is a view illustrating a process wherein a
pumping guide protrusion is ascended/descended by an
ascending/descending guide protrusion according to an exemplary
embodiment of the present invention.
[0047] Referring FIG. 4 through FIG. 7(c), when a user rotates a
container body 100 while gripping a support body 400, an
ascending/descending guide member 200 coupled to an upper portion
of the container body 100 rotates together. Due to this, a pumping
guide protrusion 310 which is secured at an upper side surface of
an ascending/descending guide protrusion 220 of the
ascending/descending guide member 200 moves along the upper side
surface of the ascending/descending guide protrusion 220 and
changes in height, such that the pumping guide member 300 is
ascended/descended. As shown in FIG. 7(a) to FIG. 7(c), when the
pumping guide protrusion 310 moves form a bottom dead point 312 of
the ascending/descending guide protrusion 220 to a top dead point
311 thereof, the pumping guide member 300 ascends, whereas the
pumping guide member 300 descends when the pumping guide protrusion
310 moves from the top dead point 311 of the ascending/descending
guide protrusion 220 to a bottom dead point 312 thereof; therefore,
the pumping guide member 300 is able to perform
ascending/descending.
[0048] Meanwhile, shown in FIG. 5, when the pumping guide member
300 ascends, an internal pressure of the content inflow part 210 is
changed by an ascent of the content suction tube 320 and causes a
first check valve 212 to open a content inflow hole 211. This makes
the contents stored in the container body 100 flow into the content
inflow part 210 through the content inflow hole 211. At this time,
a second check valve 331 installed at a valve installation part 330
keeps an open upper part of the content suction tube 320 closed. As
the pumping guide member 300 ascends, part of the contents stored
in the valve installation part 330, a content moving part 600, and
a discharging tube 520 is discharged through a discharging hole 511
of the applicator 500.
[0049] Next, as shown in FIG. 6, when the pumping guide member 300
descends, an internal pressure of the content inflow part 210
changes by a descent of the content suction tube 320, and then
causes a first check valve to close the content inflow hole 211. At
this time, a lower end of the content suction tube 320 pressurizes
an upper end of the first check valve 212, prevents the content
inflow hole 211 from being opened.
[0050] At this time, the second check valve 331 installed at the
valve installation part 330 by a pressure of the contents sucked
into the content suction tube 320 opens an open upper portion of
the content suction tube 320, such that the contents sucked into
the content suction tube 320 through the open upper portion of the
content suction tube 320 move to the valve installation part 330,
the content moving part 600, and the discharging tube 520.
[0051] As described in the above, the present invention is
configured to discharge contents by a pumping operation according
to the ascent/descent of a pumping guide member 300 when a
container body 100 rotates and to apply contents to lips by means
of an applicator 500; thus it is possible to apply liquid contents
onto lips and do a lip make-up in the same way of a conventional
stick-type lipstick.
[0052] As described above, optimal embodiments have been disclosed
in the drawings and the specification. Although specific terms have
been used herein, these are only intended to describe the present
invention and are not intended to limit the meanings of the terms
or to restrict the scope of the present invention as disclosed in
the accompanying claims. Therefore, those skilled in the art will
appreciate that various modifications and other equivalent
embodiments are possible from the above embodiments. Therefore, the
scope of the present invention should be defined by the technical
spirit of the accompanying claims.
