Description
CROSS-REFERENCE TO RELATED APPLICATION
[0001] This application claims priority of Taiwanese Application
No. 103219671, filed on Nov. 6, 2014.
FIELD
[0002] The disclosure relates to a cosmetic applicator, more
particularly to a liquid cosmetic applicator.
BACKGROUND
[0003] In cosmetic product packaging, various forms of cosmetic
containers are used according to different manners of cosmetic
application. For instance, liquid eyeliner is usually stored in a
tubular makeup container and an eyeliner applicator is dipped into
the liquid eyeliner before application. In such case, the lid of
the makeup container has to be opened for allowing access to the
liquid eyeliner paste. However, the liquid eyeliner may dry out due
to prolonged exposure to air.
[0004] In order to overcome the abovementioned drawback, there
exists a conventional type of cosmetic applicator suitable for
storing thick makeup liquid. The conventional cosmetic applicator
stores a thick makeup liquid in a receiving space and the thick
makeup liquid flows out to an applicator head without direct
exposure of the thick makeup liquid to the air. However, the thick
makeup liquid may suffer from difficulty in flowing through the
head of the applicator. In particular, when the volume of the thick
makeup liquid is decreased, it becomes harder for the liquid to
flow towards the head of the cosmetic applicator due to a decrease
of pressure in the receiving space.
SUMMARY
[0005] The purpose of the disclosure is to disclose a liquid
cosmetic applicator that can overcome the drawbacks associated with
the abovementioned prior art.
[0006] Accordingly, a liquid cosmetic applicator includes a housing
unit having a receiving space, an applicator head connected to the
housing unit, a reservoir unit, a switching unit, and a pressure
unit. The reservoir unit is disposed movably within the receiving
space and includes a cartridge. The cartridge defines a liquid
chamber that is adapted for retaining liquid cosmetic and that has
an outlet end in proximity to the applicator head. The switching
unit is connected to the housing unit and is operable for driving
movement of the reservoir unit toward the applicator head. The
pressure unit is disposed within the receiving space, and includes
a stationary pressure base and a resilient member. The stationary
pressure base is disposed between the reservoir unit and the
applicator head, and has a pressure rod portion extending into the
liquid chamber through the outlet end, and an outlet channel
extending therethrough and fluidly communicating with the liquid
chamber and the applicator head. The resilient member is disposed
for biasing the reservoir unit away from the applicator head.

DETAILED DESCRIPTION
[0012] As shown in FIGS. 1 to 3, an embodiment of a liquid cosmetic
applicator according to the present disclosure is adapted for
retaining therein a liquid cosmetic, such as liquid eyeliner, and
for applying the liquid cosmetic. The liquid cosmetic applicator
includes a housing unit 1, an applicator head 2, a cap 3, a
reservoir unit 4, a pressure unit 5, and a switch unit 6.
[0013] The housing unit 1 includes a hollow main housing body 11,
and a head-mounting seat 12 coupled to an end of the main housing
body 11 and cooperating with the main housing body 11 to define a
receiving space 13 for accommodating the liquid cosmetic. The main
housing body 11 includes a tubular wall 111 that is coupled to the
head-mounting seat 12, and an annular stop wall 113 that is
connected to an end of the tubular wall 111 opposite to the
head-mounting seat 12 and that defines a through hole 112 being in
spatial communication with the receiving space 13. The
head-mounting seat 12 includes an annular main wall 121 that abuts
against the tubular wall 111 of the main housing body 11, an
engaging wall 122 extending from the annular main wall 121 into the
tubular wall 111, and a head-mounting wall 123 extending and
converging from the annular main wall 121 in a direction opposite
to the engaging wall 122. The head-mounting wall 123 is formed with
an external thread 124.
[0014] The applicator head 2 disposed in the head-mounting wall 123
of the head-mounting seat 12, has a head portion 22 extending
outwardly of the receiving space 13, and is formed with a head
channel 21. The cap 3 is provided with an internal threaded
threadedly engaging the external thread 124 of the head-mounting
seat 12, such that the cap 3 is removably coupled to the
head-mounting seat 12 for enclosing applicator head 2.
[0015] The reservoir unit 4 is movably disposed within the
receiving space 13 of the housing unit 1 and includes a cartridge
41 filled with liquid substances, an end base 42, and a stopper 43.
The cartridge 41 includes a cartridge wall 412 defining a liquid
chamber 411 adapted for retaining the liquid cosmetic. The liquid
chamber 411 has a closed end 413 and an outlet end 414 that are
respectively distal from and proximate to the applicator head 2.
The end base 42 is disposed at the outlet end 414 of the liquid
chamber 411, and has a guiding channel 421 extending therethrough
and fluidly communicating with the liquid chamber 411. The stopper
43 is disposed inside the liquid chamber 411.
[0016] The pressure unit 5 is disposed within the receiving space
13, and includes a stationary pressure base 51 and a resilient
member 52. The stationary pressure base 51 is disposed between the
reservoir unit 4 and the applicator head 2. The stationary pressure
base 51 has a ring portion 511, an abutment portion 512, a pressure
rod portion 513, and an outlet channel 514. The ring portion 511
has opposite first and second sides. The abutment portion 512
extends from the first side of the ring portion 511 and abuts
against the applicator head 2. The pressure rod portion 513 extends
from the second side of the ring portion 511. The outlet channel
514 extends through the ring portion 511, the abutment portion 512
and the pressure rod portion 513, and fluidly communicates with the
liquid chamber 411 and the applicator head 2. The ring portion 511
has an outer diameter larger than those of the abutment portion 512
and the pressure rod portion 513. The pressure rod portion 513
extends into the liquid chamber 411 through the outlet end 414.
Specifically, the pressure rod portion 513 extends fittingly into
the guiding channel 421 and engages the guiding channel 421 in a
leak-tight manner, such that the liquid cosmetic can only flow from
the liquid chamber 411 into the outlet channel 514, and leakage of
the liquid cosmetic between the pressure rod portion 513 and the
end base 42 is not permitted. The resilient member 52 is sleeved on
the pressure rod portion 513 and has opposite ends that abut
respectively and resiliently against the second side of the ring
portion 511 and the reservoir unit 4 for biasing the reservoir unit
4 away from the applicator head 2.
[0017] The reservoir unit 4 is movable relative to the applicator
head 2 between a distal position (see FIG. 2) , where the cartridge
41 is distal from the applicator head 2 and where the stopper 43
engages and obstructs the guiding channel 421, and a proximate
position (see FIGS. 3 and 4), where the cartridge 41 is proximate
to the applicator head 2 and where the stopper 43 is disengaged
from the guiding channel 421 by the pressure rod portion 513 of the
stationary pressure base 51.
[0018] The switching unit 6 is connected to the housing unit 1, and
includes an extending switch rod 61 disposed within the receiving
space 13 of the housing unit 1, and a press rod 62 connected
co-movably to the extending switch rod 61 and extending outwardly
of the receiving space 13 via the through hole 112 of the annular
stop wall 113. The press rod 62 has a press button 621 disposed
outside of the main housing body 11.
[0019] Referring to FIG. 2, before use, the reservoir unit 4 is at
the distal position, and the pressure rod portion 513 of the
stationary pressure base 51 extends into the guiding channel 421
and is spaced apart from the stopper 43.
[0020] In use, the press button 621 of the press rod 62 is pressed
by a user, the extending switch rod 61 is moved together with the
press rod 62, and reservoir unit 4 is consequently moved by the
extending switch rod 61 toward the proximate position. During the
movement of the reservoir unit 4, the end base 42 is moved relative
to the pressure rod portion 513 toward the applicator head 2, and
the stopper 43 is moved toward the pressure rod portion 513 and is
finally pushed by the pressure rod portion 513 to be disengaged
from the guiding channel 421. At this time, the liquid cosmetic in
the liquid chamber 411 is permitted to flow to the head portion 22
of the applicator head 2 through the outlet channel 514 of the
stationary pressure base 51. Due to its viscosity, the liquid
cosmetic would be kept on the head portion 22 of the applicator
head 2 and ready for use without spilling out from the head portion
22 of the applicator head 2.
[0021] After a period of time, the amount of liquid substance of
the liquid cosmetic would be decreased and the inner pressure of
the liquid chamber 411 would too be decreased. Thus, the delivery
of the liquid substances becomes increasingly difficult. To ease or
smooth the delivery of the liquid cosmetic, the user can shake the
liquid cosmetic applicator for moving the stopper 43 to disturb the
liquid cosmetic. In addition, by pressing the switching unit 6
intermittently, pressure in the liquid chamber 411 can also be
increased. Specifically, during the movement of the reservoir unit
4 from the distal position to the proximate position, the pressure
rod portion 513 of the stationary pressure base 51 gradually
occupies the guiding channel 421. Since the liquid chamber 411
fluidly communicates with the guiding channel 421, the pressure in
the liquid chamber 411 is consequently increased.
[0022] During the movement of the reservoir unit 4 from the distal
position to the proximate position, the resilient member 52 of the
pressure unit 5 is compressed and a restoring force is generated.
Once the switching unit is released, the restoring force would bias
the reservoir unit 4 and the switching unit 6 away from the
applicator head 2.
[0023] While the disclosure has been described in connection with
what is considered the exemplary embodiment, it is understood that
this disclosure is not limited to the disclosed embodiment but is
intended to cover various arrangements included within the spirit
and scope of the broadest interpretation so as to encompass all
such modifications and equivalent arrangements.
