Description
BACKGROUND
[0001] The present invention disclosed herein relates to a
container for discharging a liquid content having an absorption
member, in particular, wherein the container is configured such
that a piston rod, having a piston and a thread formed thereon, is
integrally molded and the piston rod with the thread formed thereon
can be assembled by means of a vertical pressurization method
through a structure of a pair of guide protrusions formed inside a
guide tube, thereby increasing productivity by reducing assembly
time.
[0002] Generally, cosmetic products such as lipsticks is configured
to open a cap, to rotate a rotation body provided at a lower
portion of a container thereof, and to raise/lower a solid lipstick
to the outside of the container. For example, when a user wants to
use a lipstick, firstly the user opens a cap of a container,
rotates a rotation body, and raises the lipstick to the outside to
be protruded. After using the lipstick, the user lowers the
lipstick and makes the lipstick received in the container.
[0003] "A lipstick container" with a configuration as the above is
disclosed in FIG. 1 of the registered utility model no. 20-0241614
(hereafter called as the registered patent 1).
[0004] The registered patent 1 is characterized in that a lipstick
(2) is fitted into a lipstick holder (3), and the lipstick holder
(3) and a rotation tube (5) are coupled as a fixing protrusion (4)
of the lipstick holder (3) is being fitted into a helical groove
(6) formed at an inner portion of the rotation tube (5). A guide
tube (7) is inserted between the lipstick holder (3) and the
rotation tube (5) and coupled to the rotation tube (5) by an
annulus protrusion (5). Meanwhile, the fixing protrusion (4) of the
lipstick holder (3) is disposed inside a guide groove (8) of the
guide tube (7) and at the same time, is disposed at the helical
groove (6).
[0005] The registered patent 1 is configured in a way that the
fixing protrusion (4) hung between the helical groove (6) and the
guide groove (8) ascends when a user holds the guide tube (7) with
a hand and rotates the rotation tube (5), and thereby the lipstick
(2) fitted in the lipstick holder (3) ascends along for applying
lip make up by means of the lipstick (2); however, this type of
lipsticks composed of a solid lipstick as in the above has a
problem in that ingredients of the lipstick are likely to be
spoiled by being contacted with air.
[0006] Recently, accordingly, there have been developed a variety
of lipstick containers which are possible to minimize decomposition
of contents thereof by using liquid lipstick with the lipstick
smeared on a brush like a manicure or using the liquid lipstick
discharged by squeezing the liquid lipstick stored in the container
with a piston. A container of this type for discharging liquid
content is disclosed on Korean Registered Patent No. 10-1571466
(hereafter called as the registered patent 2).
[0007] The registered patent 2, submitted as a prior application by
the applicant of the present invention on May 26, 2015 and
registered on Nov. 18, 2015, is characterized in that, when a
rotation body rotates, liquid type contents are discharged in an
extrusion manner while a piston is ascending, and are absorbed into
an absorption member to be used, such that it is possible to
provide the same usability as a solid lipstick product which is
familiar with users and to improve spreadability of liquid content,
and by equipping a nozzle which opens only when contents are
discharged, to prevent air from flowing into the interior of the
container body when not in use.
[0008] The registered patent 2 is configured in a way that a screw
thread is formed longitudinally at the inner circumferential
surface of an ascending and descending guide member and is
assembled by screw coupling through rotation of a piston rod, and
is also configured in a way that the piston rod and the piston
should be separately assembled. Therefore, there arises a problem
that productivity decreases as assembly time increase.
[0009] Furthermore, since there is no means by which a user cannot
sense the rotation degree of the rotation body, it is hard for the
user to discharge the desired amount of contents for use.
Therefore, there arises a problem that the user may have contents
discharged unnecessarily too much.
[0010] Furthermore, since the piston is configured to descend by
counter-rotation of the rotation body, the piston should be
ascended by being rotated again as much distance as the piston
descended in order to discharge contents. This not only brings user
inconvenience but causes users to suspect the product malfunction
and to distrust the product.
SUMMARY OF THE INVENTION
[0011] The present invention is devised to solve the said problems
above, and its goal is to provide a container for discharging a
liquid content having an absorption member, wherein the container

explanatory drawing illustrating a structure of an ascending and
descending guide member and an extrusion member of a container for
discharging a liquid content having an absorption member according
to an exemplary embodiment of the present invention.
[0037] Referring to FIGS. 1 to 6, a container for discharging a
liquid content having an absorption member according to an
exemplary embodiment of the present invention includes a container
body 100, a rotation body 200, an ascending and descending guide
member 300, an extrusion member 400, and an absorption member
500.
[0038] The container body 100, where liquid content is stored, is
provided with a discharge part at the upper portion thereof such
that stored content can be discharged. The container body 100 is
preferably made of transparent material such that the color of
stored content can be checked from the outside.
[0039] The present invention is characterized in that at a lower
portion of the container body 100 is provided an elastic plate 120
which has a latch projection 121 formed. The elastic plate 120 is
composed of a pair thereof, at both sides at the lower portion of
the container body 100, respectively with incision. When a rotation
protrusion 340 pressurizes the latch projection 121 by rotation of
the rotation body 200, the elastic plate 120 is configured to move
with a limited range and then to be restored, such that it is
possible to prevent mutual interference therein in a process of the
rotation protrusion 340 going over the latch projection 121.
[0040] Furthermore, it is preferable that the latch projection 121
has one side with a first inclined surface 121a with a gentle slope
such that the rotation protrusion 340 can easily go over the latch
projection 121 when the rotation body 200 rotates, and has the
other side with a first vertical surface 121b such that the
rotation body 200 can be prevented from being counter-rotated.
[0041] Meanwhile, at the upper portion of the container body 100 is
provided a support body 600 which is coupled as encasing a
discharge part 110 of the container body 100 and supports an
absorption member 500. The support body 600 comprises a securing
part 610 where the absorption member 500 is secured, and a nozzle
part 620 which discharges contents stored in the container body 100
to the absorption member 500.
[0042] The rotation body 200, rotatably coupled as encasing the
lower portion of the container body 100, is coupled with an
ascending and descending guide member 300 which raises an extrusion
member 400 at the inner side thereof at the inner circumferential
surface of the rotation body 200 is provided a fixation groove 210
which fixes in a way that the ascending and descending guide member
300 can rotates along with the rotation body 200.
[0043] Furthermore, a separation preventing groove 220 is provided
at the inner circumferential surface of the rotation body 200 such
that the ascending and descending guide member 300 can be prevented
from moving upward and being separated in a state of the ascending
and descending guide member 300 being coupled to the rotation body
200.
[0044] Meanwhile, an over cap 800 is coupled at the upper portion
of the rotation body 200 such that the over cap 800 can encase the
container body 100 and can be attached and detached. The over cap
800 prevents contamination of the absorption member 500 and block
evaporation of content absorbed to the absorption member 500 in a
storing state without using the over cap 800.
[0045] Furthermore, at the inner upper side of the over cap 800 is
provided a closure protrusion 810 which closes the upper end of a
nozzle part 620 such that content can be prevented from being
discharged through the nozzle part 620 in a storing state.
[0046] The ascending and descending guide member 300 guides ascent
of the extrusion member 400 as being coupled to the inner side of
the rotation body 200 and rotating by rotation of the rotation body
200. For this, at the center portion of the ascending and
descending guide member 300 is provided a guide tube 310 where a
piston rod 410 of the extrusion member 400 is inserted. At the
inner upper portion of the guide tube 310 is a pair of guide
protrusions 311 which guides ascent of the extrusion member
400.
[0047] A pair of the guide protrusions 311 forms a stepped pulley
so as to be screw-coupled with a thread of the piston rod 410 when
the rotation body 200 rotates. Therefore, it is possible not only
to guide assembling through vertical compression of the extrusion
member 400 but to guide ascent of the extrusion member 400 through
a screw coupling with a thread of the piston rod 410 when the
rotation body 200 rotates.
[0048] Furthermore, at the outer circumferential surface of the
ascending and descending guide member 300 is provided a fixation
protrusion 320 which is coupled to the fixation groove 210 of the
rotation body 200 so as to be rotated according to rotation of the
rotation body 200.
[0049] Furthermore, at the outer circumferential surface of the
ascending and descending guide member 300 is provided a separation
preventing protrusion 330 which is coupled to a separation
preventing groove 220 so as to moving upwards and being separated
in a state of being coupled to the rotation body 200.
[0050] Meanwhile, the present invention is characterized in that a
plurality of rotation protrusions 340, which pressurize the latch
projection 121 by rotation of the rotation body 200, are formed
with a constant distance apart along the inner circumferential
surface at the inner side of the ascending and descending guide
member 300. When the rotation body 200 rotates, a click sound is
generated upon each rotation of the rotation body 200 and a user
can sense the rotation degree of the rotation body 200, such that
it is possible that the user can efficiently discharge desired
amount of contents through the click sound.
[0051] For example, amount of content used can vary person to
person or every time. The present invention is configured in that a
user can sense the amount of content absorbed into the absorption
member 500 every time one click sound is generate through the click
sound generated by the latch projection 121 and the rotation
protrusion 340, such that it is possible for the user to discharge
appropriate amount of content as needed by counting the number of
click sound.
[0052] Meanwhile, as illustrated in FIG. 5, one side of the
rotation protrusion 340 forms a second inclined surface 341 such
that a rotation body 200 can easily go over a first inclined
surface 121a of the latch projection 121 when the rotation body 200
rotates, and the other side of the rotation protrusion 340 forms a
second vertical surface 342 which corresponds to a first vertical
surface 121b of the rotation body 200. Therefore, it is possible to
prevent counter-rotation of the rotation body 200 because the
second inclined surface 341 of the rotation protrusion 340 after
the second inclined surface 341 of the rotation protrusion 340 and
the first vertical surface 121b of the latch projection 121 meet
after the second inclined surface 341 of the rotation protrusion
340 goes over the first inclined surface 121a of the latch
projection 121.
[0053] The extrusion member 400 ascends by rotation of the rotation
body 200 and extrudingly discharges content stored in the container
body 100. The extrusion member 400 comprises a piston rod 410 which
is inserted to the guide tube 310 of the ascending and descending
guide member 300, having a thread formed on the outer
circumferential surface thereof and ascends, and ascends by
rotation of the rotation body 200; and a piston 420, which is
disposed at the upper portion of the piston rod 410 and closely
contacted to the inner wall of the container body 100, moves as the
piston rod 410 ascends and extrudes content. It is preferable that
the piston rod 410 and the piston 420 should be integrally molded
to promote assembling.
[0054] The extrusion member 400 is configured to be closely
contacted to the inner wall of the container body 100 and to
vertically ascend in a state of being fixed to the inner wall of
the container body 100 when the rotation body 200 rotates by the
piston 420.
[0055] Meanwhile, the present invention is characterized in that a
post-processing part 700 encasing the piston rod 410 is coupled at
the extrusion member 400. As illustrated in FIG. 4, the
post-processing part 700 is configured in that one among printing,
hot-stamping, plating, metalizing, coating, or stamping can be
post-processed such that letters or figures can be marked on the
outer circumferential surface thereof. Due to this, it is possible
to provide various advertisement effects and aesthetic sense.
[0056] The absorption member 500, which absorbs liquid content
stored in the container body 100 and applies the content onto
user's lips, is configured to encase a nozzle part 620 in a state
of being secured at a securing part 610 of a support body 600 which
is coupled to the upper portion of the container body 100. It is
preferable to be made of porous material so as to improve
spreadability of the content when a user applies the content on her
lips.
[0057] Furthermore, the absorption 500 is formed with a penetration
hole 510 such that a closure protrusion 810 of the over cap 800 can
penetrate the penetration hole 510 and close the upper end of the
nozzle part 620.
[0058] Hereafter, referring FIG. 7, a using method of to a
container for discharging a liquid content having an absorption
member according to an exemplary embodiment of the present
invention will be explained. Referring FIG. 7, firstly, when a user
pressurizes the container body 100 with one hand and rotates the
rotation body 200 to one side direction, the ascending and
descending guide member 300 coupled to the inner side of the
rotation body 200 rotates together. Thus, the guide protrusion 311
of the guide tube 310 and the piston rod 410 gets screw-coupled and
thereby, the extrusion member 400 will ascend.
[0059] As in the above, when the extrusion member 400 ascends, the
piston 420 coupled to the upper portion of the piston rod 410
ascends, which pressurizes the liquid content stored in the
container body 100. Thus, the content stored in the container body
100 is discharged through the nozzle part 620 and is absorbed to
the absorption member 500. Now, it is possible for a user to apply
liquid content absorbed on the absorption member 500 onto her
lips.
[0060] As described in the above, the present invention is
configured in a way that the piston rod 410 having the piston 420
and a thread is integrally molded, and the piston rod 410 having a
thread is assembled by means of vertical pressurization through the
structure of a pair of guide protrusions 311 formed at the inner
side of the guide tube 310. Therefore, it is possible to promote
productivity by reducing assembly time. Furthermore, through the
structure of a pair of guide protrusions 311 having a stepped
pulley, it is also possible to guide ascent of the extrusion member
400 through the screw-coupling with the thread of the piston rod
410 when the rotation body 200 rotates.
[0061] 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
