[0002] Cosmetics are categorized into solid, liquid or gel-like
makeup products depending on the form. Recently, more consumers
have shown their interest in the gel-like makeup products which
have long persistence and good fit and feel when applied on skin.
However, conventional containers for gel-like makeup products as
used by consumers require that the gel-like makeup products be
inserted into a glass or tube container and thereafter consumers
squeeze or take out gel-like makeup products into hands or puff and
apply on the skin. However, consumers have to wash their hands
after taking out or squeezing out the cosmetics into their hands,
making the use of the conventional gel-like makeup product
containers uncomfortable, and also, it is difficult to uniformly
distribute the gel-like makeup products on puff.
[0003] In order to overcome the problem, Registered Utility Model
No. 20-0470757 discloses a compact container having an airless
pump. Registered Utility Model No. 20-0470757 discloses the
cosmetic filled in the container body being uniformly discharged on
a distribution member by the user's pressing the distribution
member and the pump.
[0004] However, according to Registered Utility Model No.
20-0470757, the pump is located at a central part of the
distribution member, and thus only if a user presses vertically the
central part of the distribution member, the pump will operate and
thus the cosmetics is discharged.
[0005] Therefore, a technique for solving such problems is
needed.

[0034] FIG. 1 illustrates a cosmetic container according to an
embodiment.
[0035] Referring to FIG. 1, an outer case of a cosmetic container
100 according to an embodiment may include a lower case 110 and an
upper case 160. The lower case 110 may receive a storage container
120, a pump support part 130, a pump part 140 and a discharging
plate 150 on the inside. Outside the lower case 110, there may be a
button part 111 having a non-slip bump in one area and a hinge part
(not shown) that is hinge-coupled to an upper case in another area.
The button part 111 may cause the upper case 160 to break away from
the non-slip bump as the non-slip bump that is extended to an upper
part of the button part recedes due to a press motion of a
user.
[0036] An upper case 160 may be hinge-coupled to a lower case 110
and may open or close the lower case 110 to or from outside. In
addition, a mirror, etc. may be provided on an inner
circumferential surface of an upper case 160, which makes use of
the cosmetic container 100 easier.
[0037] FIG. 2 is a perspective view illustrating a cosmetic
container according to an embodiment.
[0038] Referring to FIG. 2, a cosmetic container 100 may include a
storage container 120, a pump support part 130, a pump part 140 and
a discharge plate 150.
[0039] The storage container 120 receives cosmetics, and there may
be a receiving groove 121 at a central area. A connecting part
connecting with a cosmetic storage space of the storage container
120 may be formed at a lower part of the receiving groove 121, and
the cosmetics may be discharged to outside via the connecting part.
The cosmetics received in the storage container 120 may be selected
from liquid sun cream, liquid powder, BB cream, lotion or cream,
but is not limited thereto; various liquid cosmetics can be
accommodated according to an embodiment.
[0040] A pump support part 130 may support a pump part 140, and at
the same time, be coupled to a storage container 120. As such, a
groove part 131 having a predetermined depth may be formed at a
central area of the pump support part 130, and the pump part 140
may be provided in the groove part 131. In addition, the groove
part 131 may be coupled to a receiving groove 121 of the storage
container 120. For example, the coupling may be done by screw
coupling along a screw line formed in the groove part 131 and/or
receiving groove 121. However, this is for illustration purpose
only, and the way of coupling is not limited thereto.
[0041] Furthermore, at least one guide groove 132 may be formed in
an inner circumferential surface of an edge of the pump support
part 130. In particular, the guide groove 132 may include a dent
area 132_1 and a non-slip projection 132_2. The dent area 132_1 may
be formed by denting of the inner circumferential surface of the
edge of the pump support part 130 and may receive a protruding part
152_1 of the discharge plate 150 and at the same time may provide a
downward movement space of the protruding part 152_1. In addition,
the non-slip projection 132_2 may be formed on an upper end of the
dent area 132_1 by the denting of the inner circumferential surface
of the edge, and therefore the non-slip projection 132_2 may
prevent the protruding part 152_1 of the discharge plate 150 from
moving upward, and at the same time, a force may occur centered
around the non-slip projection 132_2 which presses down on a rod
141 as the protruding part 152_1 is supported by the non-slip
projection 132_2.
[0042] According to an embodiment, the number, position, size, etc.
of the guide groove 132 formed in the pump support part 130 may
vary. In other words, as illustrated in FIG. 2, if a dent area
132_1 and/or non-slip projection 132_2 is restricted to have a
predetermined width, the movement of the protruding part 152_1 to
the right or to the left will be limited and thus the loss of a
pressing force from the rotation or turn of the discharge plate 150
may be prevented. Also, as to be further described with reference
to FIG. 7, the dent area 132_1 and/or non-slip projection 132_2 may
be formed over the entire inner circumferential surface of the
edge. Here, the discharge plate 150 may also form at least one
protruding part 152_1 in various positions.
[0043] The pump part 140 may discharge the cosmetics in the storage
container 120 to outside via the discharge plate 150. The pump part
140 may be inserted in the groove part 131. Furthermore, a rod 141
protruding to an upper part of the groove part 131 may be formed at
a central area of the pump part 140. When there is a press motion
on the discharge plate 150, a lower part surface of the discharge
plate 150 contacts and presses the rod 141, and a pumping motion of
the pump part 140 may be performed. Detailed description on each
element of the pump part 140 will be described below in more detail
with reference to FIG. 3.
[0044] The discharge plate 150 may transmit a pressing force from a
user to a pump part 140 and discharge cosmetics transferred by the
pump part 140 to outside. The discharge plate 150 may include a
lower plate 151 and an upper plate 152.
[0045] In particular, the lower plate 151 may be provided between
the upper plate 152 and the pump part 140. The cosmetics
transferred by the pump part 140 may move downward, below a
discharge hole 152_2 of the upper plate 152 via a diffusion space
formed between the lower plate 151 and the upper plate 152. For
this process, a diffusion groove 151_1 having a radial shape, for
example, which guides transfer of cosmetics, may be formed on a
surface of the lower plate 151. The discharge hole 152_2 of the
upper plate 152 may respectively be at an upper part of the
diffusion groove 151_1. Furthermore, the lower plate 151 may be
coupled to an upper end of the pump part 140 such that airtight
sealing may be possible, and when the discharge plate 150 is
pressed, the cosmetics being transferred from the pump part 140 to
the lower plate 151 may be prevented from being exposed to
outside.
[0046] The upper plate 152, when pressed by a user, may move
downward and may press the rod 141 of the pump part 140. In
particular, the upper plate 152 may be spaced from an upper part
surface of the pump support part 130 at certain distance intervals
and arranged, and at least one protruding part 152_1 capable of
being inserted in the guide groove 132 of the pump support part 130
may be formed as protruding towards an outside direction in at
least one area outside of the upper plate 152. The upper plate 152
may contact a puff of a user as the upper part surface is exposed
to outside. There may be at least one discharge hole 152_2 through
which cosmetic is discharged in one area of the upper part surface.
Furthermore, to accommodate a puff, etc. of a user in a stable
manner, a central area of the upper part surface of the upper plate
152 may have a dent shape which is dent towards inside. However,
this is only an example, and the upper plate 152 may be realized in
various different ways according to an embodiment.
[0047] FIG. 3 illustrates a pump part of a cosmetic container
according to an embodiment.
[0048] Referring to FIG. 3, a pump part 140 may include a housing
part 142, a check valve part 143, a piston rod 144, a guide piston
145, a first sealing part 146, a spring part 147 and a second
sealing part 148.
[0049] A housing part 142 may include a storage space inside, and a
through hole, through which cosmetic flows in, may be formed on a
lower part surface. In other words, the housing part 142 may flow
the cosmetics discharged from the storage container 120 into the
pump part 140 via the through hole. As a piston rod 144 moves up
and down, a space may be provided in which the pump part 140 can
operate.
[0050] A check valve part 143 may be positioned on a lower end of
the storage space of the housing part 142 and may open and close
the through hole. In other words, the check valve part 143 may open
or close the through hole depending on the downward or upward
movement of the piston rod 144, thereby flowing cosmetics into the
housing part 142 or block the inflow.
[0051] The piston rod 144 may be provided on an upper part of the
check valve part 143 of a storage space of the housing part 142 and
may include a cylinder formed outside and a rod 141 formed inside
the cylinder. Here, at least one inflow hole may be formed on a
surface of the cylinder such that cosmetics can be transferred from
the check valve part 143 into the cylinder, and the rod 141, having
received the pressure transferred from the discharge plate 150, may
move the piston rod 144 downward. The piston rod 144 that has moved
downward may be restored upward by an elastic force of the spring
part 147. Also, an upper end of an inner circumferential surface of
the cylinder may be coupled to at least one area of the lower part
surface of the discharge plate 150 such that airtight sealing may
be possible, and thus when there is a pumping motion of the pumping
part 140, the cosmetics may be made not to be leaked to other
external areas but only to the discharge plate 150.
[0052] The guide piston 145 may be closely provided between an
inner side surface of the housing part 142 and an outer side
surface of the piston rod 144 and may guide upward and downward
movement of the piston rod 144. When there is a pumping motion of
the piston rod 144, depending on the upward or downward movement of
the piston rod 144, the guide piston 145 may be fixed and/or move
along in piston rod 144 line therewith. Therefore, it may
respectively couple to the piston rod 144 or form a certain
interval space from the piston rod 144, cosmetics may be discharged
from the check valve part 143 and move into the piston rod 144.
[0053] A first sealing part 146 may be fix-coupled to an upper part
of a housing part 142 and seal the housing part 142 with a second
sealing part 148. As a result, cosmetics may not be spilled to
outside of the housing part 142, not going through the piston rod
144.
[0054] A spring part 147 may wrap around an outer circumference
surface of the housing part 142 and may restore a position of the
piston rod 144 that moved downward which changed due to user's
pressing action. In other words, if pressing force is removed, the
spring part 147 may move upward the second sealing part 148 coupled
to the spring part 147. Here, the piston rod 144 coupled to the
second sealing part 148 may together move upward, and the position
of the piston rod 144 which changed due to pressure may be together
restored.
[0055] The second sealing part 148 may be provided on an upper part
of the first sealing part 146, and at least one area may be
inserted such that an interval space between the first sealing part
146 and an outer surface of the cylinder of the piston rod 144 can
be airtight sealed. The second sealing part 148 may be provided on
an upper part of the spring part 147 and may move downward together
when the piston rod 144 moves downward due to pressure from a user,
compressing the spring part 147 thereby generating an elastic
force. Thereafter, if a pressing force is removed, the position of
the piston rod 144 may be restored by moving upward.
[0056] FIG. 4 is a cross-sectional view of a cosmetic container
according to an embodiment.
[0057] In particular, FIG. 4(a) illustrates the discharge plate
before being pressed, and FIG. 4(b) illustrates the discharge plate
being pressed.
[0058] Referring to FIG. 4, a rod 141 is provided at a central area
of the discharge plate 150. As a result, even if a user presses any
area of the discharge plate 150, the difference in force that is
transmitted to the rod 141 may be minimized.
[0059] In addition, if the central area of the discharge plate 150
is pressed, the discharge plate 150 may move downward without being
slanted and press the rod 141. However, if a pressing motion takes
place at a peripheral area of the discharge plate 150, the rod 141
may function as a central axis of a lever, and a torque in an
opposite direction of the pressure may be acted on in an opposite
area which is symmetrical to one area where a pressure is acted on,
with respect to the rod 141. If the torque is not removed, even if
the discharge plate 150 is pressed, the discharge plate 150 may
only cause the rod 141 to be slanted towards an axis, and the
pressure may not end up being transmitted to the rod 141.
[0060] In order to overcome the problem, in the present invention,
an upward movement of the protruding part 152_1 inserted in a guide
groove 132 of the pump support part 130 is restricted to a non-slip
projection 132_2. That is, even if a torque is in action in an
opposite area, the upward movement of the protruding part 152_1
located in the opposite area is restricted by the non-slip
projection 132_2, and the non-slip projection 132_2 may offset the
torque. Accordingly, the discharge plate 150 may slant downward
with respect to the non-slip projection 132_2 as the center axis,
the pressing force is transmitted to the rod 141, and the pump part
140 may operate. In addition, the dent area 132_1 of the guide
groove 132 may extend downward from an insertion position of the
protruding part 152_1, and the downward movement of the discharge
plate 150 in the area where pressure acts on may be made
possible.
[0061] As such, through the protruding part 152_1 and the guide
groove 132, the slanting of the discharge plate 150 may be
minimized. Accordingly, even if any area of the discharge is
pressed, the discharge plate 150 may press the rod 141, thereby
easily discharging the cosmetics.
[0062] In the meantime, at least one elastic member 170 may be
provided between the discharge plate 150 and the pump support part
130. The elastic member 170 may restore the position of the
discharge plate 150. After the pressing motion takes place,
depending on the restoration of the state of the pump part 140, the
rod 141, while moving upward, may not only restore the location
and/or position of the discharge plate 150, but also the elastic
member 170 may provide an elastic force towards an upper part if
the discharge plate 150 is slanted or does not sufficiently rise by
the rod 141, thereby readily assisting restoration of the location
and/or position of the discharge plate 150.
[0063] FIG. 4 illustrates the rod 141 acting on as a central axis
of a lever, but this is only an example, and different
element/structure of the pump part 140 may function as a central
axis of a lever according to an embodiment.
[0064] FIGS. 5 and 6 illustrate shapes of a rod of a pump part
according to an embodiment. FIGS. 5(a) and 6(a) illustrate the
discharge plate before being pressed, and FIGS. 5(b) and 6(b)
illustrate the discharge plate being pressed.
[0065] In particular, referring to FIGS. 5 and 6, rods 141 and 141'
may include a convex end part touching a lower part surface of
upper plates 152 and 152', and there may be a concave area whose
shape corresponds to the convex end part in an area touching the
rods 141 and 141' among the lower part surfaces of the upper plates
152 and 152'. The convex end part and the concave area may be
formed to have a gentle curve surface in at least one area.
Accordingly, for example, if the upper plates 152 and 152' are
slanted and press down on the rods 141 and 141', by increasing the
touching surfaces of the rods 141 and 141' touching the upper
plates 152 and 252, the pressing force is stably transferred to the
lower direction of the rods 143 and 243, and at the same time, the
slanting of the upper plates 152 and 152' may be made smoother in a
gentle slope.
[0066] The shapes of the convex end part and the concave area are
for illustrative purposes only, and as shown in FIGS. 5 and 6, the
shapes of the convex end part and the concave area, for example,
the degree of curvature or cutting may be realized in various
different ways according to an embodiment.
[0067] FIG. 7 illustrates the shape of a pump support part
according to an embodiment.
[0068] Referring to FIG. 7, one guide groove 132 may be formed in a
pump support part 130. In other words, a dent area 132_1 and/or
non-slip projection 132_2 of the guide groove 132 may be formed
over the entire inner circumferential surface of the edge. Here,
the discharge plate 150 may also form at least one protruding part
152_1 in various positions.
[0069] By simplifying the constitution of the guide groove 132 and
protruding part 152_1, the manufacture is rendered easy and the
process unit price is reduced, and thus the invention may be
realized at a better economic cost.
[0070] Example embodiments have been disclosed herein, and although
