Description
TECHNICAL FIELD
[0001] The present invention relates to a lip package for
accommodating a liquid cosmetic, and more particularly, to a lip
package for dispensing a desired amount of a flowable liquid
cosmetic such as lip gloss, wherein upon pressing a button formed
on the exterior of the container, an actuating member disposed
within the container raises a piston to dispense a predetermined
amount of the liquid cosmetic contained in the container, thereby
improving convenience of use and enabling the use thereof with one
hand due to the button type structure.
BACKGROUND ART
[0002] Generally, lip glosses are flowable liquid cosmetics used
for preventing damage to lips, maintaining desired colors and
glossiness of the lips and obtaining healthy conditions and beauty
effects of the lips.
[0003] A lip package for accommodating such a lip gloss comprises a
cosmetic brush rod consisting of a cylindrical rod part formed
integrally with or coupled to a grip and a brush part fixedly
inserted into a lower end of the rod part, and a container body
with liquid lip gloss accommodated therein, as shown in FIG.
11.
[0004] At this time, the container has a mouth through which only a
minimal amount of the liquid lip gloss is brought into contact with
outside ambient air. Accordingly, the rod part is formed to be
elongated such that upon insertion thereof into the container, a
lower end of the brush part fixedly inserted into the rod part is
in contact with a bottom surface of the container, and to have a
diameter such that it can enter and be withdrawn from the container
through the container mouth. When the brush part of the brush rod
is smeared with the liquid lip gloss due to repeated vertical
movement of the brush rod, the brush rod is withdrawn from the
container and then used for applying the lip gloss to the desired
region of the human body.
[0005] However, since this lip package is constructed such that the
brush rod with the brush part fixed thereto is withdrawn from the
container body and then used, there is a problem in that if a great
amount of the liquid lip gloss is accommodated in the container
body, the rod part as well as the brush part become smeared with an
excessive amount of lip gloss, thereby causing one's lip and even
the skin therearound to be smeared with liquid lip gloss.
[0006] Further, since the brush part of the brush rod should be
smeared with the liquid lip gloss whenever the lip gloss is used,
the brush rod should be often engaged with and disengaged from the
container. At this time, there is a problem in that since bristles
of the brush part often come into contact with the mouth of the
container, the bristles may be curved outwardly or twisted, or come
out. Moreover, since the bristles quickly harden when they are
exposed to the atmosphere for a long time, there is a problem of
inconvenience of use due to the hardened brush part and the
like.
[0007] To solve the aforementioned problems, as shown in FIG. 12,
Korean Patent Laid-Open Publication No. 10-2003-0015539
(Application No. 10-2001-0049313) entitled "Container for liquid
type lip pencil" discloses a container comprising a container body
110 for accommodating a lipstick liquid 100; a tip 120 rotatably
coupled to an upper portion of the container body, and a lid 130; a
brush body 140 and a brush B that vertically come out or are
retracted in response to rotation of the tip 120; a lower knob 150
rotatably coupled to a lower portion of the container body 110; an
inner screw 160 operated in response to rotation of the lower knob
150; a screw bar 170 with a piston 171 at a top end thereof
vertically moved by the inner screw 160; and a tube 180 installed
to allow the liquid in the container body to reach a lower end of
the brush according to the leading of the piston 171. A
circumferential ridge 113 of the lower knob 150 is engaged with a
circumferential groove at the lower portion of the container body
110 so that the lower knob 150 can be rotated. As the lower knob
150 is rotated, protrusions 154 at an upper circumference of the
lower knob ride over protrusions 164 of the inner screw 160 to
generate click sounds and female threads 152 of the lower knob 150
are simultaneously engaged with threads of the screw bar 170 to
rotate and move the screw bar by a predetermined pitch. The piston
171 coupled to the top end of the screw bar 170 urges the liquid
100 accommodated in the container body 110, and the lipstick liquid
passes through the tube 180 and is then absorbed by the brush. In
such a manner, lipstick liquid is hermetically accommodated in the
container and gradually dispensed in response to the rotation of
the lower knob 150.
[0008] However, to apply make-up using the container for such a
liquid type lip pencil, the container body 110 should be grasped by
one hand and the lower knob 150 should be grasped and rotated by
the other hand. That is, since the both hands should be used, there
is a problem of inconvenience upon applying make-up while looking
in a portable mirror or the like.
[0009] The lid 130 is in a coupled state when the container for a
liquid type lip pencil is not in use. However, since the lower knob
150 can be rotated even when the lid 130 is coupled to the
container body 110, there is a risk of delivery of the liquid,
which leads to a problem in which the interior of a bag with the
container stored therein is smeared with the liquid.
[0010] Further, since the container for the liquid type lip pencil
has the brush having a plurality of bristles that have a
predetermined length, there are problems in that the entire lengths
of the bristles should be smeared with the lipstick liquid thus a
great amount of the lipstick liquid is consumed, and the lipstick
liquid is also rapidly dried.
[0011] Moreover, the process of manufacturing the container for the
liquid type lip pencil is complicated due to the coupling structure
of the lower knob 150 for dispensing the liquid and the coupling
structure for causing the brush body 140 to come out from the
container body 110. Since most containers for liquid cosmetics with
such a structure are formed to be elongated and slim in terms of
aesthetics, there is a disadvantage in that only about 1.5 to 2.0
ml of liquid cosmetics can be accommodated in the container body
110.
DISCLOSURE OF INVENTION
[0012] The present invention is conceived to solve the
aforementioned problems in the prior art. Accordingly, an object of
the present invention is to provide a lip package, wherein upon
pressing a button formed on an outer peripheral surface of a
cylinder, an actuating member disposed within a container body is
operated to raise a piston so that a liquid cosmetic accommodated
in the cylinder can be delivered, thereby achieving convenience of
use and delivery of the liquid cosmetic with one hand due to the
button type structure in a state where the Hp package is grasped by
the hand, and applying make-up rapidly and conveniently even with
one hand.
[0013] Another object of the present invention is to provide a lip
package with a locking function by which a button cannot be
operated when a lid is coupled to a container body.
[0014] A further object of the present invention is to provide a
lip package that can be more easily used due to a delivery member
for delivering a liquid cosmetic, which is in the form of a general
lipstick.
[0015] A still further object of the present invention is to
provide a lip package, wherein a porous absorption member for
receiving a liquid cosmetic is fitted over a delivery member,
thereby more easily applying the liquid cosmetic to the skin.
[0016] A still further object of the present invention is to
provide a lip package, wherein an inner structure for delivering a
liquid cosmetic is simply constructed to accommodate a great amount
of the liquid cosmetic.
[0017] According to the present invention for achieving the
objects, there is provided a lip package, comprising a container
body with a push button protruding from an outer circumferential
surface thereof; a cylinder coupled to the container body, for
containing a liquid cosmetic; a delivery member coupled to the
cylinder and having a top surface formed with a plurality of
delivery holes; a piston that has the same shape and size as a
cross section of the cylinder and is raised along an inner
circumferential surface of the cylinder to pressurize the liquid
cosmetic; and an actuating member that is accommodated within the
container body and vertically raises the piston in response to a
push operation of the push button to deliver the liquid cosmetic
through the delivery member.
[0018] The lip package may further comprise a lid detachably
coupled to an outer circumferential surface of the cylinder to
close the delivery member. The push button may protrude from the
outer circumferential surface of the container body so that upon
coupling of the lid to the outer circumferential surface of the
cylinder, an end of the lid can be fitted into a fixing recess of
the push button to fix the push button.
[0019] The top surface of the delivery member may be formed to be
inclined with respect to a cross section of the cylinder and have a
plurality of delivery holes therein.
[0020] The lip package may further comprise an absorbing member,
including a sponge, for covering the top surface of the delivery
member.
[0021] The actuating member may comprise a nut plate to be rotated
in response to the push operation of the push button; and a screw
bar that is threadly engaged with the nut plate and raised in
response to the rotation of the nut plate, whereby the piston
coupled to the screw bar may be raised in response to the rising of
the screw bar.
[0022] The actuating member may comprise a cam vertically raised in
response to the push operation of the push button; and a screw bar
that is engaged with the cam through coupling of corresponding
convex and concave portions and raised together the cam by a
distance through which the cam is raised, whereby the piston
coupled to the screw bar may be raised in response to the rising of
the screw bar.
[0023] The push button may comprise a button portion outwardly
protruding through a through-hole of the container body; and a
moving portion extending from a side of the button portion and
fixed within the container body. Both sidewalls of the moving
portion are formed with guide rails having a level difference for
operating the actuating member, and distal end surfaces of the
sidewalls are formed with coupling recesses to which an elastic
member is coupled to allow the push button to be horizontally
moved. Coupling protrusions of the cam may be inserted into the
guide rails of the push button so that the cam can be vertically
raised in response to horizontal movement of the guide rails. The
screw bar may be vertically raised in response to the vertical
rising of the cam.
[0024] The actuating member may further comprise a supporting
member placed below the cam and coupled to the screw bar in a
ratchet manner to support the vertical rising of the screw bar.
Advantageous Effect
[0025] The lip package of the present invention comprises a push
button protruding outside of a container body, an actuating member
operated by pressing the push button, a piston vertically raised by
the actuating member, and a delivery member coupled to a cylinder
to deliver a liquid cosmetic. When a user presses the push button,
the liquid cosmetic contained in the cylinder is delivered in a
predetermined amount, resulting in easy use thereof. Further, since
the user can grasp the container body with one hand and press the
push button with a finger of the hand grasping the container body,
the user can apply make-up using only one hand. Thus, there is
provided a more convenient lip package.
[0026] Further, since the push button protruding outside of the
cylinder is formed with the fixing recess, and upon coupling of the
lid to the cylinder, the lid is fitted into the fixing recess of
the push button to fix the push button, the lid performs a locking
function when the lid is coupled to the cylinder after applying
make-up. Thus, there is provided a lip package having no risk of
leakage of the liquid cosmetic to the outside.
[0027] Moreover, since the top surface of the delivery member
through which the liquid cosmetic is delivered to the outside has
an inclined surface similarly to a top surface of a general solid
lip stick, there is provided a lip package that enables much easier
application of the liquid cosmetic to the skin.
[0028] Furthermore, since the soft absorbing member with high
absorbency is coupled to the top surface of the delivery member and
the liquid cosmetic is absorbed by the absorbing member, there is
provided a lip package that enables much effective application of
the liquid cosmetic to the skin and has a superior feel of the
applicator to the skin.
[0029] In addition, since the cylinder and the lid are formed
similarly to those of a general solid lip stick in size and shape
and thus have large inner spaces, there is provided a lip package
capable of containing a great amount of liquid cosmetic.

BEST MODE FOR CARRYING OUT THE INVENTION
[0038] Hereinafter, a lip package of the present invention for
specifically achieving the objects will be described with reference
to the accompanying drawings. Particularly, liquid lip gloss is
employed as a liquid cosmetic in embodiments of the present
invention.
[0039] FIG. 1 is a perspective view showing a lip package according
to a first embodiment of the present invention, and FIG. 2 is an
exploded perspective view showing a state where components of the
lip package according to the embodiment shown in FIG. 1 are
disassembled. In the lip package of this embodiment, a delivery
member 2, a piston 3, a push button 4, an actuating member 6 and a
lower cap 5 are received in a container body 1, and liquid lip
gloss 9 (see FIGS. 3 and 4) is contained in a cylinder 11 coupled
to the container body 1. Here, although the container body 1 and
the cylinder 11 are formed integrally with each other, they will be
described separately in view of features of their uses since the
container body 1 receives actuating components therein and the
cylinder 11 contains the liquid lip gloss 9 therein.
[0040] The container body 1 defines a space for accommodating the
actuating components for delivering the liquid lip gloss 9. The
cylinder 11 for containing the liquid lip gloss 9 is coupled to an
upper portion of the container body 1, and the actuating components
for upwardly delivering the liquid lip gloss 9 are accommodated
within a lower portion of the container body 1 below the cylinder
11. Here, since an outer circumferential surface of the cylinder 11
has a diameter smaller than that of an outer circumferential
surface of the container body 1, a stepped portion 16 is formed at
a junction between the cylinder 11 and the container body 1.
[0041] The cylinder 11 defines a space for containing the liquid
lip gloss 9. A neck portion 13 that is a passage through the liquid
lip gloss 9 is delivered is formed inside of a rim 12 of the
cylinder 11. The neck portion 13 is formed to have a diameter
smaller than that of the rim 12. Thus, a coupling groove 14 with a
predetermined width and depth is formed between the rim 12 and the
neck portion 13 so that the delivery member 2 to be described later
can be fitted thereinto. The lower portion of the container body 1
is formed with an opening 17 through which the actuating member 6
and the lower cap 5 are coupled to the container body 1.
[0042] Further, a through-hole 15 with a predetermined size is
formed at a side of the cylinder 11 so that a button portion 41 of
the push button 4 to be described later can be engaged with the
through-hole 15. More specifically, the through-hole 15 is formed
at a portion of the container body 1 where the stepped portion 16
is formed.
[0043] The diameter of an inner circumferential surface of a lid 7
is identical with that of the outer circumferential surface of the
cylinder 11. The lid is fitted over the upper portion of the
container body 1 and then lowered toward and caught by the stepped
portion 16 defining a boundary between the cylinder 11 and the
container body 1 so that it can be integrated with the cylinder
11.
[0044] The delivery member 2 is a means for delivering the liquid
lip gloss 9 contained in the cylinder 11 to the outside through the
neck portion 13. A lower portion of the delivery member 2 is open
to communicate with the neck portion 13, and a top surface 24 of
the delivery member is formed with a plurality of delivery holes
25. A protruding flange 21 to be seated on the rim 12 of the
cylinder 11 is formed around an outer circumferential surface of
the delivery member. A fitting portion 22 with a width and length
corresponding to the width and depth of the coupling groove 14
extends from a lower portion of the flange 21 so that it can be
fitted into and fixedly engaged with the coupling groove 14 of the
cylinder 11.
[0045] Further, a recess 23 connected to the outer circumferential
surface of the delivery member 2 extending downwardly from the top
surface 24 is formed inside of the flange 21, so that a porous
absorbing member 8 (see FIG. 6) with high absorbency such as a
sponge can be caused to cover the top surface 24 and to have a
distal end thereof fitted into the recess 23.
[0046] Preferably, the top surface 24 is formed to be slanted
similarly to a general solid lipstick, to take the shape of a flat
circle, or to be tapered toward the center thereof.
[0047] The piston 3 is a means for urging the liquid lip gloss 9
contained in the cylinder 11 toward the delivery member 2. The
piston 3 is in the form of a disk with a certain thickness. To
prevent the liquid lip gloss 9 from leaking downwardly, the piston
3 is formed to have the same shape and size as a cross section of
the inner circumference of the cylinder 11. The center of the
bottom of the piston 3 is formed with a fitting recess 31 into
which a screw bar 60 of the actuating member 6 for raising the
piston 3 is fitted. Moreover, the piston 3 is made of silicone or a
resilient synthetic resin so that when the piston 3 is disposed
within the cylinder 11, the piston 3 is press-fitted into the
cylinder 11 and fully hermetically seals the interior of the
cylinder 11 due to properties of the material of the piston. Thus,
the liquid lip gloss 9 is prevented from flowing downwardly of the
cylinder 11. Since the piston 3 can move due to the properties of
the material thereof when an external force is applied thereto, it
is raised while urging the liquid lip gloss 9.
[0048] The push button 4 is a means for transmitting an external
force to the actuating member 6 to raise the piston 3. The push
button 4 comprises the button portion 41 mounted in the
through-hole 15 of the cylinder 11 to transmit the external force,
and an operating portion 46 fixed attached to the inner
circumferential surface of the container body 1 and coupled to the
button portion 41 so as to rotate a nut plate 70 of the actuating
member 6.
[0049] The button portion 41 comprises a pressing section 42 with a
predetermined size such that a user can press thereon, a connection
section 43 horizontally extending from a lower end of the pressing
section 42 rearward, and a coupling section 44 vertically upwardly
extending from a distal end of the connection section 43. The
coupling section 44 is fixedly coupled to the operating portion 46,
and a lower surface of the connection section 43 is seated on a
lower portion of the through-hole 15, so that the pressing portion
42 can move in a fore and aft direction. Here, the pressing section
42 is sized to be smaller than the through-hole 15 such that it can
freely move within the through-hole 15 in the fore and aft
direction, while the coupling section 44 is sized to be larger than
the through-hole 15 such that the coupling section 44 cannot come
out.
[0050] The operating portion 46 is formed to have a circumferential
length larger than the circumference of the container body 1 such
that it can have a slight surplus length while covering the inner
circumferential surface of the container body 1. A resilient
projection 48 of the operating portion 46 is formed to take the
shape of a flat panel with a predetermined length and thickness to
be fitted between adjacent teeth 73 formed on the nut plate 70 of
the operating member 6. The operating portion 46 will be described
below by dividing it into a bonding surface 47 to be bonded to the
inner circumferential surface of the container body 1, a
non-bonding surface 47' coupled to the button portion 41, and the
resilient projection 48.
[0051] When the bonding surface 47 is fixedly bonded to cover the
remainder of the inner circumferential surface of the container
body 1 except the through-hole 15, the non-bonding surface 47'
extending from the bonding surface 47 is placed at the through-hole
15. The coupling section 44 of the button portion 41 inserted into
the container body 1 through the through-hole 15 is bonded to and
integrated with the non-bonding surface 47'. Since the resilient
projection 48 extending from the non-bonding surface 47' is formed
to be inwardly curved, the resilient projection 48 is in contact
with the teeth 73 of the actuating member 6.
[0052] Therefore, when an external force is applied to the button
portion 41, the connection section 43 of the button portion 41 is
pushed into the through-hole 15, and at the same time, the
non-bonding surface 47' of the operating portion 46 integrated with
the coupling section 44 of the button portion 41 moves inwardly or
rearwardly. Then, the resilient projection 48 extending from the
non-bonding surface 47' pushes one of the teeth 73 of the actuating
member 6 and angular positions of the teeth 73 are changed. When
the external force is removed, the button portion 41 returns to its
original position and the operating portion 46 is also restored to
its original state due to its elasticity. Accordingly, the
resilient projection 48 comes into contact with another tooth
adjacent the tooth 73.
[0053] Although the button portion 41 and the operating portion 46
are formed separately from each other, it is possible to form them
integrally.
[0054] Further, when the lid 7 is coupled to the container body 1
in a state where the button portion 41 of the push button 4 has
been installed in the container body 1, the lid 7 is lowered while
being slid on the outer circumferential surface of the container
body 1 and then seated in the connection section 43 of the button
portion 41 installed in the through-hole 15. That is, since the
coupling section 44 of the button portion 41 is placed on the inner
circumferential surface of the container body 1 through the
through-hole 15, the pressing section 42 of the button portion 41
is placed outside of the container body 1, and the connection
section 43 for connecting the pressing section 42 to the coupling
section 44 is seated on the lower portion of the through-hole, a
lower end of the lid 7 is seated in a fixing recess 45 at the
connection section 43, whereby the lid is coupled to the container
body 1. Therefore, the push button 4 is in a fixed state where it
cannot be operated due to the lid 7.
[0055] The operating member 6 is a means for raising the piston 3
while being rotated by means of the operation of the push button 4.
The operating member 6 comprises the nut plate 70 rotated by the
resilient projection 48 of the push button 4, the screw bar 60
vertically raised through thread engagement with the nut plate 70
to raise the piston 3, an elastically supporting ring 80 to which
the nut plate 70 is coupled in a ratchet manner so that it can be
rotated by a predetermined pitch only in one direction, and an
elastic member 90 for supporting the elastically supporting ring 80
to maintain the contact of the elastically supporting ring 80 with
the nut plate 70.
[0056] The screw bar 60 is formed to take the shape of an elongated
rod and has an outer circumferential surface formed with threads 61
that will be engaged with threads 75 formed in a central bore 74 of
the nut plate 70. An upper end of the screw bar is fixedly fitted
into the fitting recess 31 of the piston 3. Further, at least one
guide groove 62 with a predetermined depth is longitudinally formed
throughout an entire length of the screw bar 60 on an outer
circumferential surface thereof.
[0057] A disk 71 of the nut plate 70 is formed to have a diameter
smaller than that of the inner circumference of the container body
1 so that it can be rotated within the lower portion of the
container body 1. Here, the diameter of the disk 71 is determined
such that the disk is caught by the operating portion 46 fixed to
the container body 1 and thus cannot be raised beyond the operating
portion. A gear shaft 72 protruding upwardly from the center of the
disk 71 is formed to have a predetermined length such that the
resilient projection 48 of the operating portion 46 comes into
contact with the gear shaft. An entire outer circumferential
surface of the gear shaft 72 is formed with the vertically
protruding teeth 73 that are sized to correspond to the thickness
of the resilient projection 48. Further, the central bore 74 is
longitudinally formed through the nut plate 70 at the center of the
nut plate 70, i.e. the center of the disk 71 and the gear shaft 72,
so that the screw bar 60 can be inserted into the central bore. An
inner circumferential surface of the central bore 74 is formed with
the threads 75 corresponding to the threads 61 formed on the outer
circumferential surface of the screw bar 60. Thus, when the nut
plate 70 is rotated after the screw bar 60 has been inserted into
the central bore 74 of the nut plate 70, the screw bar 60 is
vertically upwardly raised through the thread engagement thereof
with the threads 75 formed in the central bore 74.
[0058] Moreover, a lower surface of the disk 71 is formed with a
plurality of ratchet teeth 76 radially around the central bore 74
and at a predetermined interval. Since each of the ratchet teeth 76
is in the form of a right-angled triangle, the nut plate 70 can be
rotated only in one direction. The ratchet teeth 76 are formed at
the predetermined interval corresponding to a certain pitch, so
that when the nut plate 70 is rotated in a state where the disk 71
is assembled with the elastically supporting ring 80 to be
described later, the screw bar 60 is raised (refer to operating
states shown in FIGS. 3 and 4).
[0059] The elastically supporting ring 80 is formed to take the
shape of a cylinder with open top and bottom faces and to have a
diameter slightly smaller than that of the disk 71 so that the
elastically supporting ring 80 can be inserted into a lower portion
of the disk 71 of the nut plate 70 and then coupled in a ratchet
manner thereto. A circumferential portion of the upper face of the
elastically supporting ring 80 is formed with at least one ratchet
pawl 81 cooperating with the ratchet teeth 76 of the nut plate 70.
When the nut plate 70 is rotated after the elastically supporting
ring 80 has been inserted into the lower portion of the disk 71 of
the nut plate 70, the nut plate 70 can be rotated only in one
direction due to the cooperating configuration of the ratchet teeth
76 and the ratchet pawl 81. Moreover, at least one ridge 82 is
formed to protrude vertically outwardly from an outer
circumferential surface of the elastically supporting ring 80. When
the elastically supporting ring 80 is inserted into a seating
recess 55 of the lower cap 5, the ridge 82 of the elastically
supporting ring 80 is fitted into a supporting groove 57 formed on
an inner circumferential surface of a cylindrical rod 56 of the
lower cap 5 so that the elastically supporting ring 80 can be in a
fixed state not to be interlocked with the rotation of the nut
plate 70.
[0060] The elastic member 90 is formed of a spring with high
elasticity and serves as a means for supporting the elastically
supporting ring 80 and the nut plate 7. The elastic member applies
an elastic force to the lower portion of the elastically supporting
ring 80 so that the nut plate 70 coupled in a ratchet manner to the
elastically supporting ring 80 seated in the seating recess 55 of
the lower cap 5 can be easily rotated in place.
[0061] The lower cap 5 comprises a bottom surface 51 for closing
the lower portion of the container body 1 with the opening 17
formed therein, the cylindrical rod 56 upwardly extending such that
the bottom surface 51 can be coupled to the container body 1
through the opening 17, and a spline 52 upwardly extending from the
center of the bottom surface 51 to support the screw bar 60 of the
actuating member 6 in such a manner that the screw bar can be
vertically raised. Here, the seating recess 55 into which the
elastically supporting ring 80 and the elastic member 90 are fitted
is defined between the cylindrical rod 56 and the spline 52. The
vertical lengths of the cylindrical rod 56 and the spline 52 are
determined to receive the coupled elastic member 90 and elastically
supporting ring 80 as a whole.
[0062] Further, at least one supporting groove 57 is vertically
formed on the inner circumferential surface of the cylindrical rod
56 so that when the elastically supporting ring 80 is inserted into
the seating recess 55, the ridge 82 of the elastically supporting
ring 80 is fitted into the supporting groove 57. Thus, the
elastically supporting ring 80 can be vertically moved due to the
elastic member 90 but prevented from being rotated. The spline 52
is formed with an inner bore 53 into which the screw bar 60 is
fitted. An inner circumferential surface of the inner bore 53 is
vertically formed with a guide protrusion 54 along the entire
length of the inner circumferential surface to correspond to the
guide groove 62 of the screw bar 60. Accordingly, when the screw
bar 60 is inserted into the inner bore 53 of the spline 52, it is
inserted thereinto while the guide groove 62 of the screw bar 60 is
fitted over the guide protrusion 54 of the spline 52. Thus, the
screw bar 60 can be vertically raised but cannot be rotated.
[0063] In the lip package according to the first embodiment of the
present invention constructed as above, the delivery member 2 is
coupled to the upper portion of the cylinder 11, and the piston 3
with the screw bar 60 fixed thereto is installed within the
container body 1 coupled to the cylinder 11. The operating portion
46 and the button portion 41 are installed inside and outside of
the cylinder 11 with respect to the through-hole 15, respectively.
The nut plate 70 is rotatably installed below the operating portion
46. The resilient projection 48 of the operating portion 46 is in
contact with the gear shaft 72 of the nut plate 70, the screw bar
60 is screwed into the central bore 74 of the nut plate 70, and the
elastically supporting ring 80 and the elastic member 90 are
sequentially assembled into the lower portion of the nut plate 70.
At this time, the elastically supporting ring 80 and the elastic
member 90 are contained in the seating recess 55 of the lower cap
5, and the screw bar 60 protruding through the central bore 74 of
the nut plate 70 is also fitted into the inner bore 53 of the
spline 52 formed in the lower cap 5. The lower cap 5 is
press-fitted into the opening 17 of the container body 1.
[0064] Next, the operating principle of the lip package according
to the present invention constructed as above will be described
with reference to FIGS. 3 and 4. In the figures, the liquid lip
gloss 9 is contained above piston 3 installed within the cylinder
11 of the lip package. For reference, a tooth 73 of the nut plate
70 with which the resilient projection 48 of the push button 4 is
in contact before the push button 4 of the lip package is pressed
is herein referred to as "A" and another tooth 73 with which the
resilient projection 48 of the push button 4 is in contact after
the pressing force is removed from the push button 4 of the lip
package is herein referred to as "B".
[0065] In a state where a user grasps the container body 1 with one
hand, he/she presses the pressing section 42 of the button portion
41 protruding from a side of the cylinder 11. The connection
section 43 connected to the pressing section 42 is pushed into the
container body 1 through the through-hole 15, and the coupling
section 44 that extends from the connection section 43 and is
placed inside of the through-hole 15 and coupled to the non-bonding
surface 47' of the operating portion 46 is moved together with the
non-bonding surface 47' toward the interior of the cylinder 11.
With the horizontal movement of the non-bonding surface 47' of the
operating portion 46, the resilient projection 48 of the operating
portion 46 that is in contact with the gear shaft 72 of the nut
plate 70 of the actuating member 6 pushes the tooth 73 (A) of the
gear shaft 72, thereby rotating the gear shaft 72. When the force
applied to the button portion 41 is removed, the button portion 41
returns to its original position due to an elastic force from the
non-bonding surface 47' of the operating portion 46, and the
resilient projection 48 comes into contact with the tooth 73 (B)
moved in response to the rotation of the gear shaft 72. Here, the
screw bar 60 that has been screwed into the central bore 74 of the
nut plate 70 is vertically raised through the thread engagement
thereof with the threads 75 of the central bore 74 as the nut plate
70 is rotated, and the piston 3 fixed coupled to the upper end of
the screw bar 60 upwardly urges and pressurizes the liquid lip
gloss 9. Therefore, the liquid lip gloss 9 is delivered from the
top surface 24 of the delivery member 2 through the delivery holes
25 thereof via the neck portion 13 of the cylinder 11.
[0066] Since the lower surface of the disk 71 of the nut plate 70
is formed with the ratchet teeth 76 at a predetermined pitch and
the ratchet pawl 81 is formed on the upper face of the elastically
supporting ring 80 for supporting the lower surface of the disk 71
so that the nut plate 70 and the elastically supporting ring 80 are
constructed to be coupled to each other in a ratchet manner, and
the elastically supporting ring 80 is supported by the elastic
member 90 at the lower portion thereof, the nut plate 70 is rotated
by the predetermined pitch by means of the elastically supporting
ring 80 fixedly coupled to the cylindrical rod 56 to raise the
screw bar 60 by a predetermined distance. Further, since the screw
bar 60 is in a state where it is inserted into the inner bore 53
formed in the spline 52 of the lower cap 5, i.e. in a state where
the guide groove 62 of the screw bar 60 is fitted over the guide
protrusion 54 of the inner bore 53, the screw bar 60 can be raised
or lowered without rotation.
[0067] After use of the liquid lip gloss 9, the lid 7 is coupled to
the cylinder 11 to close the cylinder as shown in FIG. 5. The lid 7
is lowered while riding on the outer circumferential surface of the
cylinder 11 to reach the stepped portion 16 and to be fitted into
the fixing recess 45 of the button portion 41 installed within the
through-hole 15 formed at a side of the stepped portion 16. In such
a manner, the lid 7 is coupled to the cylinder 11. When the lid 7
is fitted into the fixing recess 45 of the button portion 41, the
button portion 41 is in a fixed state where it cannot move in the
through-hole 15. That is, a structure like a lock is established.
Accordingly, even though an external force is applied to the push
button 4, the button portion 41 and the operating portion 46 and
the actuating member 6 and 6a cooperating therewith are not
operated, thereby preventing the liquid lip gloss 9 from being
delivered to the outside through the delivery member 2.
[0068] Furthermore, the delivery member 2 through which the liquid
lip gloss 9 is delivered may have the top surface 24 that is in the
form of a convex dome or an inclined surface like a general solid
lipstick for easier use thereof, or is tapered toward the center
thereof. Preferably, the porous absorbing member 8 with high
absorbency such as a sponge is coupled to the top surface 24 of the
delivery member 2 as shown in FIG. 6 so that the liquid lip gloss 9
delivered through the delivery member 2 can permeate into the
absorbing member 8. Thus, the feel of the applicator to the lip is
good and the liquid lip gloss 9 absorbed by the absorbing member 8
can be more easily applied to the lip.
[0069] Moreover, since the cylinder 11 and the lid 7 are formed
similarly to a lipstick container for accommodating a solid lip
stick in size and shape, a large inner space can be obtained. Thus,
the cylinder 11 can contain about 3.0 ml of liquid lip gloss 9
therein.
[0070] FIG. 7 is an exploded perspective view showing a lip package
according to a second embodiment of the present invention. The lip
package according to the second embodiment of the present invention
comprises a container body 1 for accommodating a delivery member 2,
a piston 3, a push button 4a, an actuating member 6a and a lower
cap 5a, and a cylinder 11 for containing liquid lip gloss 9 coupled
to the container body.
[0071] Here, since the container body 1, a lid 7, the cylinder 11,
the delivery member 2 and the piston 3 have the same configurations
as those of the first embodiment of the present invention described
above, detailed descriptions thereof will be omitted.
[0072] The push button 4a is a means for transmitting an external
force to the actuating member 6a to raise the piston 3. The push
button 4a comprises the button portion 41a outwardly protruding
through a through-hole 15 of the cylinder 11, and a moving portion
46a that extends from an end of the button portion 41a and is
placed within the container body 1 to operate the actuating member
6a to be described later.
[0073] The button portion 41a comprises a pressing section 42a
protruding outwardly of the container body 1 through the
through-hole 15 of the cylinder 11, a connection section 43a
horizontally extending from a lower end of the pressing section 42a
to the inside of the cylinder 11, and a coupling section (not
designated by a reference numeral) upwardly extending vertically
from a distal end of the connection section 43a. The coupling
section is coupled to the moving portion 46a. Here, the pressing
section 42a and the coupling section are sized to be smaller than
the through-hole 15 such that they can be easily moved within or
inserted into the through-hole 15.
[0074] The moving portion 46a is formed to have a " "-shaped cross
section. Both sidewalls 47a of the moving portion 46a are formed
with guide rails 48a for operating a cam 70a of the actuating
member 6a to be described later. Distal end surfaces of the both
sidewalls 47a are formed with coupling recesses 49a to which an
elastic member 90a for applying an elastic force to the push button
4a is coupled. Therefore, the push button 4a can be horizontally
moved due to an external force and then restored to its original
state by means of the elastic member 90a. Further, the guide rails
48a have a predetermined horizontal length such that the cam 70a of
the actuating member 6a is moved according to the movement of the
push button 4a. Each of the guide rails 48a is formed such that one
end S is at a level lower than that of the other end E.
[0075] The actuating member 6a is a means for raising the piston 3
by means of the operation of the push button 4a, and comprises the
cam 70a that is coupled to the push button 4a and movable according
to the movement of the push button, a screw bar 60a that can be
vertically raised by the means of the operation of the cam 70a to
raise the piston 3, a supporting member 80a for supporting the
weight of the screw bar 60a, and the elastic member 90a for
applying the elastic force to the push button 4a.
[0076] The screw bar 60a is inserted into the cam 70a to be raised
by means of the operation of the cam 70a. The screw bar 60a is
formed to take the shape of a rectangular rod of which one of four
sides is formed with a plurality of teeth 61a at a predetermined
pitch over the entire length thereof. Opposite both sides of
remaining three sides of the screw bar are longitudinally formed
with guide ridges 62a, respectively. The teeth 61a are teeth in the
form of a right-angled triangle with an inclined surface only in
one direction.
[0077] The cam 70a is coupled to the push button 4a and the screw
bar 60a to raise the screw bar 60a according to the horizontal
movement of the push button 4a. The cam 70a is in the form of a
tube with a central bore 74a of a predetermined size such that the
screw bar 60a can be inserted thereinto. Outer surfaces of opposite
both sidewalls of the cam 70a are formed with coupling protrusions
77a to be coupled to the guide rails 48a of the push button 4a.
Inner surfaces of the both sidewalls with the coupling protrusions
77a formed thereon are formed with guide grooves 78a into which the
guide ridges 62a of the screw bar 60a are fitted. An inner surface
of another sidewall of the cam is formed with a protruding
resilient pawl 79a that comes into contact with one of the teeth
61a of the screw bar 60a when the screw bar 60a has been coupled to
the central bore 74a of the cam 70a. Thus, the cam can be coupled
to the screw bar 60a in a ratchet manner.
[0078] The supporting member 80a is seated in a cylindrical hollow
rod 56a of the lower cap 5a, which will be described later, to
support the push button 4a, the cam 70a, and the teeth 61a of the
screw bar 60a. The supporting member 80a is formed to have a
diameter identical with that of an inner circumference of the
container body 1, and has a top surface 83a for supporting lower
portions of the push button 4a and the cam 70a and an open bottom
face. The top surface 83a is formed with a central hole 84a into
which the screw bar 60a is inserted. A supporting pawl 86a
protrudes from a portion of a lower end of the supporting member
80a toward the interior of the supporting member 80a to support the
teeth 61a of the screw bar 60a, thereby being engaged with one of
the teeth 61a of the screw bar 60a in a ratchet manner. Further,
connection holes 85a into which the elastic member 90a is fitted
are formed at predetermined positions on the top surface 83a.
[0079] The elastic member 90a is a means for applying the elastic
force to the push button 4a. The elastic member is in a fixed state
where a lower end thereof is fitted into a fixing recess 59a of the
lower cap 5a and upper ends thereof are fitted into the coupling
recesses 49a of the moving portion 46a of the push button 4a.
[0080] The lower cap 5a comprises a bottom surface 51a for closing
a lower portion of the container body 1 with an opening 17 formed
therein, and the cylindrical hollow rod 56a upwardly extending such
that the bottom surface 51a is coupled to the container body 1
through the opening 17. The fixing recess 59a into which the lower
end of the elastic member 90a is fitted is formed in a protrusion
58a protruding from the bottom surface 51a with a predetermined gap
with respect to an inner circumferential surface of the cylindrical
hollow rod 56a.
[0081] Therefore, in the lip package according to the second
embodiment of the present invention constructed as above, the
delivery member 2 is coupled to an upper portion of the cylinder
11, and the piston 3 with the screw bar 60a fixed thereto is
installed within the cylinder 11. The moving portion 46a of the
push button 4a and the button portion 41a are installed inside and
outside of the container body 1 with respect to the through-hole 15
of the cylinder 11, respectively. The coupling protrusions 77a of
the cam 70a of the actuating member 6a are fitted into and coupled
to the guide rails 48a of the moving portion 46a. Below the cam
70a, the supporting member 80a is seated in and assembled into the
cylindrical hollow rod 56a of the lower cap 5a. Here, the screw bar
60a is inserted into the central bore 74a of the cam 70a and then
into the central hole 84a of the supporting member 80a so that the
teeth 61a of the screw bar 60a are engaged with the supporting pawl
86a of the supporting member 80a in a ratchet manner. The upper
ends of the elastic member 90a with the lower end fitted into the
fixing recess 59a of the lower cap 5a protrude through the
connection holes 85a of the supporting member 80a and are then
inserted into the coupling recesses 49a of the moving portion 46a.
At this time, one of the teeth 61a of the screw bar 60a is in
contact with the pawl 79a of the cam 70a, and the supporting member
80a is installed below the cam 70a such that the screw bar 60a is
inserted into the central bore 84a of the supporting member 80a.
Further, since the guide ridges 62a of the screw bar 60a are fitted
into the guide grooves 78a of the cam 70a, the screw bar 60a can be
vertically raised in a stable state.
[0082] Next, the operating principle of the lip package according
to the second embodiment of the present invention constructed as
above will be described. Here, the liquid lip gloss 9 is contained
within the cylinder 11 of the lip package. For reference, a tooth
61a of the screw bar 60a with which the pawl 79a of the cam 79a is
in contact before the push button 4a of the lip package is pressed
is herein referred to as "C" and another tooth 61a with which the
pawl 79a of the cam 79a is in contact after the pressing force is
removed from the push button 4a is herein referred to as "D".
Further, a tooth 61a of the screw bar 60a with which the supporting
pawl 86a of the supporting member 80a is in contact before the push
button 4a of the lip package is pressed is herein referred to as
"M" and another tooth 61a of the screw bar 60a with which the
supporting pawl 86a of the supporting member 80a is in contact
after the pressing force is removed from the push button 4a is
herein referred to as "N".
[0083] FIG. 8 shows a state where an external force is not applied
to the push button of the lip package according to the second
embodiment of the present invention, i.e. a state where the button
portion 41a of the push button 4a protrudes outside of the cylinder
11 through the through-hole 15, the coupling protrusions 77a of the
cam 70a of the actuating member 6a coupled to the guide rails 48a
of the moving portion 46a of the push button 4a are located at the
ends S of the guide rails 48a, the pawl 79a of the cam 70a is
caught in the tooth 61a (C) of the screw bar 60a, and the
supporting pawl 86a of the supporting member 80a located below the
cam 70a is caught in the tooth 61a (M) of the screw bar 60a.
[0084] FIG. 9 shows a state where an external force is applied to
the push button of the lip package according to the second
embodiment of the present invention. In a state where a user grasps
the container body 1 with one hand, he/she presses the button
portion 41a of the push button 4a protruding from a side of the
cylinder 11. The button portion 41a is horizontally moved in the
direction of the pressing force, and the moving portion 46a formed
integrally with the button portion 41a and placed within the
container body 1 is also horizontally moved by the displacement of
the button portion 41a while pushing the elastic member 90a fixed
to the moving portion 46a.
[0085] Then, with the horizontal movement of the moving portion
46a, the coupling protrusions 77a of the cam 70a come out from the
ends S of the guide rails 48a and are located at the other ends E
of the guide rails. At this time, since the ends S of the guide
rails 48a are formed at a level lower than that of the other ends E
thereof, the change in the positions of the coupling protrusions
77a of the cam 70a to the other ends E of the guide rails 48a
results in the vertical rising of the cam 70a by the level
difference between the ends S and the other ends E of the guide
rails 48a, and the vertical rising of the screw bar 60a due to the
upward pushing of the tooth 61a (C) of the screw bar 60a by the
pawl 79a of the cam 70a. At this time, when the screw bar 60a is
vertically raised, the supporting pawl 86a that has supported the
tooth 61a (M) of the screw bar comes into contact with the tooth
61a (N) due to the rising of the screw bar 60a and then supports
the screw bar 60a.
[0086] As shown in FIG. 10, when the pressing force is removed from
the push button 4a, the button portion 41a returns to its original
position by means of the elastic force of the elastic member 90a,
and the coupling protrusions 77a of the cam 70a are also moved to
the ends S of the guide rails 48a. At this time, since the
supporting pawl 86a of the supporting member 80a is in contact with
the tooth 61a (N) of the screw bar 60a to support the screw bar 60a
by means of the operation shown in FIG. 9, the pawl 79a of the cam
70a is slid on an inclined surface of the tooth 61a and caught in
the tooth 61a (D) of the screw bar 60a. Further, the pawl 79a of
the cam 70a can be more smoothly moved to the tooth 61a (D) of the
screw bar 60a due to its own elasticity.
[0087] That is, when the force that has been applied to the push
button 4a is removed therefrom, the pawl 79a of the cam 70a is
moved from the tooth 61a (C) to the tooth 61a (D) of the screw bar
60a, and the supporting pawl 86a of the supporting member 80a is
also moved from the tooth 61a (M) to the tooth 61a (N) of the screw
bar 60a to support a lower portion of the screw bar 60a.
[0088] Therefore, when the screw bar 60a is raised, the piston 3
coupled to the screw bar 60a and installed within the cylinder 11
is also raised to urge the liquid lip gloss 9. Thus, the liquid lip
gloss 9 is delivered to the outside through the delivery holes 25
of the delivery member 2 installed at the upper portion of the
cylinder 11.
[0089] Since the button portion 41a of the push button 4a and the
lid 7 of the lip package according to the second embodiment of the
present invention also have the same coupling structure as those of
the lip package according to the first embodiment, the assembly of
the lid 7 to the container body 1 when the lip package is not in
use causes the lid 7 to be fitted into a fixing recess 45a of the
button portion 41a so that the push button 4a cannot be operated,
thereby establishing a locking function.
