Description
DESCRIPTION
[0001] This application claims foreign priority of Korean Patent
Application No. 10-2011-0022233, filed on Mar. 14, 2011, which is
incorporated by reference in its entirety into this
application.
TECHNICAL FIELD
[0002] The present invention relates to a cosmetic container
including an airless pump, and more particularly, to a cosmetic
container including an airless pump that improves Korean Patent No.
963155 of the applicant and in which contents can be safely and
sanitarily stored for a long time by using a triple storage
container, a pump performs a pumping operation through an operation
of moving forward and rearward from a rear side to a front side to
improve a pumping efficiency, various types of cosmetics are
received at the same time to be conveniently used and be
refilled.
BACKGROUND ART
[0003] The structures of cosmetic containers for storing cosmetics
are different according to various states of the cosmetics such as
liquid, powder, and gel, and tube type containers are mainly used
to effectively store cosmetics in the state of gel or liquid.
[0004] The tube type cosmetic containers are formed of a flexible
material such as aluminum, laminate, or a synthetic resin to safely
and effectively protect contents direct rays or ultraviolet rays,
discharging contents through an inlet hole by a force of
compressing a surface thereof from the outside.
[0005] However, the tube type cosmetic container can be safely and
effectively store contents due to material characteristics of a
tube, but since the tube is formed of a soft material, the entire
volume of the tube is reduced by a discharge amount of contents.
Thus, an external appearance of the tube is deformed as the tube is
used.
[0006] Since the external shape of the tube is gradually distorted
as the tube is used, the original external shape cannot be
maintained. Thus, the external shape of the tube is not desirable
and a product value is significantly lowered. Further, preservation
efficiency is damaged by the deformed external shape and the tube
cannot be handled properly.
[0007] In addition, the conventional cosmetic container has a
structure in which an opening is opened and closed with a cap to
discharge contents by pressing a surface thereof, it has a
structural problem in which external air cannot help but be always
introduced and a problem in which it is difficult to accurately
discharge a suitable amount of cosmetics during use thereof.
[0008] Accordingly, in recent years, structures in which a separate
airless pump is mounted to an opening of a tube have been proposed
to solve the above-described problem, and the applicant also
proposed Korean Patent No. 963155.
[0009] In the patent of the applicant, a cosmetic container has a
dual structure including an inner container having a flexible tube
shape and an outer container formed of a synthetic resin, and a
separate airless pump that is vertically elevated is installed in
openings thereof.
[0010] Thus, in the patent of the applicant, a determined outer
shape of the cosmetic container is maintained by the outer
container irrespective of an amount of used cosmetics so that the
cosmetic container can be conveniently carried, preserved, and
used. Further, a precise amount of cosmetics can be discharged by
the airless pump and external air and foreign substances cannot be
introduced. Furthermore, a precise amount of contents can be
discharged from the cosmetic container during use thereof.
[0011] However, the patent of the applicant has the following
drawbacks in spite of the various advantages.
[0012] First, although the patent has a dual structure in which a
flexible tube type inner container is installed in a hard outer
container, volatile cosmetics that is vulnerable to ultraviolet
rays cannot be safely protected by the dual structure.
[0013] That is, although cosmetics can be protected from
ultraviolet rays by a tube type inner container formed of aluminum,
laminate, and a synthetic resin, some cosmetics cannot be
completely protected only by the inner container.
[0014] Further, since the airless pump is installed on a front
surface of the tube type inner container and an operation button
that is operated by a push operation can be pushed vertically, an
operation of the airless pump is very inconvenient and a pumping
force is also lowered.
[0015] That is, since the operation button has a small size and
only a portion of the operation button protrudes upward, it is not
easy to push the operation button with a finger and the operation
button should be pushed while the entire container is gripped by
another hand.
[0016] Further, the cosmetics in the inner container are
horizontally pumped while the operation button is vertically
pushed, a discharge flow of the contents is not smooth and an
accurate pumping operation may not be performed.
DISCLOSURE
Technical Problem
[0017] The present invention has been made in an effort to solve
the above-mentioned problems, and it is an object of the present
invention to provide a cosmetic container including an airless pump
that overcomes the structural problems of Korean Patent No. 963155
of the applicant.
[0018] That is, it is an object of the present invention to provide
a cosmetic container including an airless pump that includes a
triple container body, safely and sanitarily stores cosmetics by
using an airless pump mounted to a front surface of the cosmetic
container, allows a tube container to be replaced after the
cosmetic container is completely used to refill the cosmetics.
[0019] Another object of the present invention is to provide a
cosmetic container including an airless pump an entire external
appearance of which forms a flat, horizontal, and compact shape to
improve an external appearance and a product value thereof and
forms a plurality of reception spaces therein so that various types
of cosmetics can be received and conveniently used.
[0020] In particular, the present invention provides a cosmetic
container including an airless pump in which a pump is operated by
pushing the airless pump from the rear side and the pump is moved
forwards and rearwards in a horizontal direction coinciding with a
direction in which the contents are extracted to improve an
operation of the pump and an extraction of the contents.
Technical Solution
[0021] In order to achieve the objects, the present invention is
achieved by providing an improved cosmetic container, and the
cosmetic container of the present invention includes a tube
container horizontally installed to safely store various cosmetics,
a hard protection cap configured to protect the tube container and
to dually protect the cosmetics again, and a compact case formed of
a hard synthetic resin, the case having a plurality of reception
chambers into which various types of cosmetics can be received at
an upper portion thereof while being protected by a tube container
and a protection cap, whereby cosmetics case can be effectively and
safely stored for a long time due to the triple container body.
[0022] Further, since the airless pump is installed at a front end
of the tube container and the operation button is installed at a
rear side of the case so that the pump is operated in a direction
coinciding with a horizontal direction in which the contents are
discharged, an operation of the pump can be improved and a
discharge efficiency of the contents can be improved.
Advantageous Effects
[0023] The present invention can safely and effectively protect
cosmetics received into a tube container from external rays or
ultraviolet rays due to a container body having a triple structure
of the tube container, the protection cap, and the case formed of
different materials.
[0024] In particular, the tube container and the protection cap
forms an integrally assembled single product so that they can be
replaced. Thus, the cosmetics of the tube container can be refilled
after being completely used.
[0025] Further, since the airless pump can be installed on a front
surface of the tube container side by side and can be horizontally
moved forwards and rearwards by the operation button, an
installation structure can be improved. Furthermore, since a
pumping operation can be performed in the same direction in which
the contents are discharged, the pumping operation can be smoothly
and flexibly performed. An addition, the contents can be discharged
accurately and smoothly.
[0026] In addition, the present invention can interrupt
introduction of external air or foreign substance by the airless
pump and the structure and prevent vaporization of the cosmetics
from the interior, making it possible to safely store the cosmetics
for a long time.

BEST MODE
Mode for Invention
[0041] Hereinafter, detailed contents for carrying out the present
invention will be described in detail with reference to the
accompanying drawings.
[0042] FIGS. 1 to 7 are views showing an entire configuration of
the present invention. FIGS. 8 to 11 are views showing an internal
configuration of the present invention in detail. FIGS. 12 to 15
are views showing an operation of the present invention. In the
drawings, reference numeral 100 denotes a body of the present
invention.
[0043] The body 100 of the cosmetic container mainly includes a
case 10 opened and closed by a cap while maintaining an overall
appearance, a reception body 20 coupled to the case 10 and having a
plurality of reception chambers for receiving cosmetics at an upper
surface thereof, a tube container 30 inserted into the case 10 to
store cosmetics, the tube container 30 being protected by a
separate protection cap 32, an airless pump 40 integrally coupled
to a front surface of the tube container 30 to pump contents to the
outside by a predetermined amount, and an operation button 50
installed on a rear surface of the case 10 to operate the airless
pump 40 through a push operation.
[0044] In more detail, the case 10 is formed of a hard synthetic
resin to have a horizontally flat shape and the separate reception
body 20 is coupled to an interior of the case 10 to be opened and
closed by the cap 12 shaft-coupled to the case 10. A separate
mirror 13 is installed in the cap 13.
[0045] In particular, the case 10 is a container body that is not
vertically erected but horizontally laid to exhibit a unique
design. A compact container having various shapes including a
circle, a tetrahedron, and a polygon may be formed according to
various embodiments.
[0046] The separate reception body 20 coupled to the case 10
includes a plurality of cosmetic reception chambers 21, 22, and 23
on an upper surface thereof, and a nozzle hole 21a through which
contents are pumped and discharged from the tube container is
perforated in the main reception chamber 21 and a cosmetic tool 60
formed of a separate sponge material is installed in the main
reception chamber 21.
[0047] In this case, different types of cosmetics are received in
the remaining reception chambers 22 and 23 other than the main
reception chamber 21 to achieve a convenience for use, and the
remaining reception chambers 22 and 23 may have various shapes such
as a circle and a tetrahedron.
[0048] The separate tube container 30 and the airless pump 40 are
mounted to an interior space between the case 10 and the reception
body 20 after being integrally assembled.
[0049] As shown in FIGS. 6 to 11, the tube container 30 and the
airless pump 40 are integrally coupled to each other side by side
to form a single product, and a front end of the tube container 30
and the airless pump 40 remains fixed by a stopper 14 integrally
formed on a bottom surface of an interior of the case 10.
[0050] The tube container 30 is formed of a flexible material such
as a laminator, aluminum, a synthetic resin, and rubber to easily
store cosmetics mainly in the form of liquid or cream, and an
ejection hole 31 for discharging contents is formed of a hard
synthetic material at one side thereof.
[0051] Thus, direct light that is an ultraviolet ray cannot
penetrate the tube container 30 due to its material characteristics
so that contents can be safely stored, and the tube container 30
can be easily compressed by an impact or a push operation due to
its flexible tube so that contents can be discharged through the
ejection hole.
[0052] The tube container 30 is also protected by the separate
protection cap 32, and the protection cap 32 is formed of a hard
synthetic resin to have a box shape. The tube container 30 is
inserted into the protection cap 32 to be safely protected.
[0053] The separate airless pump 30 is integrally mounted to a
front surface of the tube container 30.
[0054] The airless pump 40 provides a function of accurately
discharging contents in the tube container 30 by a predetermined
amount, and is integrally coupled to the tube container 30 and the
protection cap 32 in a single form so that all of them can be
replaced together.
[0055] All of them can be made to be replaced together so that a
new tube container 30 can be replaced to refill contents after all
the cosmetics in the tube container 30 are used.
[0056] As can be seen from the drawings, in the structure of the
airless pump 40, an engaging tube 41 is interference-fitted with
the ejection hole 31 of the tube container 30, an operation tube 42
is coupled to a front surface of the engaging tube 41 to proceed or
retreat due to a resilient force of the spring 43, and an operation
cylinder 44 inserted into the ejection hole 31 of the tube
container 30 is engaged with a rear surface of the engaging tube
41.
[0057] The engaging tuber 41 and the operation tube 42 have
cylindrical shapes, and a spring 43 is resiliently installed
therebetween. Guide grooves 42a are formed at upper and lower sides
of the rear surface of the operation tube 42 to be opened and guide
pins 41a inserted into the guide grooves 42a to be slid are formed
at upper and lower portions of a front end of the engaging tube
41.
[0058] Thus, since the engaging tube 41 and the operation tube 42
are coupled as the guide pins 41a are coupled to the guide grooves
42a, they can move forwards and rearwards but cannot rotate.
[0059] The engaging tube 41 is interference-fitted with an outside
of the ejection hole 31 of the tube container 30 to maintain a
sealed state, and the operation cylinder 44 installed at a rear
side thereof is interference-fitted with an inside of the ejection
hole 31 of the tube container 30 to maintain a sealing state with
the tube container 30.
[0060] The operation cylinder 44 has a cylindrical shape and an
outlet through which contents in the tube container 30 are
discharged is formed at an end thereof. A compression chamber 44a
communicated with the outlet is formed in the operation cylinder
44, and a separate valve 45 is engaged with the outlet to be opened
and closed as the contents are discharged.
[0061] The valve 45 is a check valve configured to open and close
the outlet of the operation cylinder 44 in the compression chamber
44a, and allows discharge of contents and prevents the contents
from being introduced reversely.
[0062] A cylindrical piston 42b is integrally formed with an
interior of the operation pipe 42, and the piston 42b has a
cylindrical tube shape extending rearwards by a predetermined
length and a separate piston support 46 is engaged with the
interior of the piston 42b rearwards.
[0063] The piston support 46 also has a cylindrical shape, and one
end thereof has a saw tooth-shaped wing 46a to be coupled to an
inner surface of the operation cylinder 44 such that the
compression chamber 44a in the operation cylinder 44 is formed and
the operation cylinder 44 can be smoothly supported so that the
operation cylinder 44 may be slid and the contents may smoothly
flow.
[0064] Ribs 46b for smooth flow of contents alternately protrude
from a surface of the piston support 46 and an exit hole 46c for
circulating contents from the outside to the inside to discharge
the contents to the outside is formed at a predetermined location
of the body to be communicated with the interior of the body.
[0065] A piston valve 47 is installed in the operation cylinder 44
to interrupt and open a space between the operation cylinder 44 and
the piston support 46, and is preferably formed of a very flexible
material such as rubber, urethane, and a synthetic resin to secure
a sealed state.
[0066] Meanwhile, a separate nozzle 48 as shown in FIGS. 14 and 15
is coupled to a front end of the operation tube 42.
[0067] The nozzle 48 has a vertically bent shape and is stably
supported by the stopper 14 in the case 10 without being moved, so
that an end thereof is coupled to the nozzle hole 21a perforated in
the reception chamber 21 of the reception body 20 to be
communicated with the nozzle hole 21a.
[0068] That is, the nozzle 48 is formed of a flexible material such
as rubber or a synthetic resin and a cutting line 48a having a "+"
shape is formed at an end of the nozzle 48. The end of the cutting
line 48a close the nozzle hole 21a in a standby state in which the
reception chamber 21 is firmly coupled to a bottom surface of the
nozzle hole 21a so that the contents are not discharged, and is
widened to the outside to smoothly discharge the contents through
the nozzle hole 21a when the contents are pumped to be
discharged.
[0069] An operation button 50 is coupled to ends of the case 10 and
the reception body 20. The operation button 50 has a vertically
bent shape and is coupled to a portion of the case 10 and a portion
of the reception body 20 to be exposed to the outside so that the
protection cap 32 of the tube container 30 may be moved by a push
operation.
[0070] That is, the operation button 50 is coupled between the case
10 and the reception body 20 in an operation range A including a
horizontal direction of the case and a vertical direction of the
reception body 20 so that a push operation is allowed in any of the
horizontal direction and the vertical direction in the operation
range A. Accordingly, a smooth pumping operation can be achieved
even if a force is applied to any of the horizontal direction and
the vertical direction in the operation range A.
[0071] Thus, the cosmetic container 100 of the present invention
may effectively store cream mainly in the form of gel in the tube
container 30, and may be suitably used as a compact cosmetic
container having a flat shape that is not vertical but horizontal
as a whole.
[0072] That is, the tube container 30 for storing cosmetics is
received and preserved in the case 10 by the separate protection
cap 32. Accordingly, since cosmetics are triply protected by the
tube container 30, the protection cap 32, and the case 10, the
cosmetics can be protected from external rays or ultraviolet rays
very effectively and safely and can be carried and used very
conveniently due to its flat and compact structure.
[0073] The reception body 20 installed in the case 10 has a
plurality of reception chambers 21, 22, and 23 such that the
reception chambers 22 and 23 other than the main reception chamber
21 may receive cosmetics other than the cosmetics in the tube
container 10 so that various types of cosmetics are selectively
used.
[0074] As shown in FIG. 12, when the cosmetics in the tube
container are to be used in this state, the operation button 50 is
pushed while the cap 12 is opened. Then, the hard protection cap 32
that protects the tube container 30 is moved forward by the push
force, and the airless pump 40 performs a pumping operation as the
entire protection cap 32 is moved forward.
[0075] The pumping operation of the airless pump 40 is performed by
moving the protection cap 32 forwards. The operation tube 42 is
moved forwards as the engaging tube 41 compresses the spring 43
while the operation tube 42 is fixed to the stopper 14 of the case
10, and the operation cylinder 44 and the piston value 47 are moved
forwards at the same time.
[0076] Thus, cosmetics filled in the compression chamber 44a of the
operation cylinder 44 are compressed and are fed through spaces
between the saw tooth-shaped wings 46a of the piston support 46 and
between the ribs 46b generated by the piston value 47 that has been
moved forward. Then, the cosmetics are fed through the exit hole
46c of the piston support 46 and then are discharged into the
reception chamber 21 of the reception body 20 via the nozzle
48.
[0077] Then, as can be seen in FIG. 15, the cosmetics discharged
through the nozzle 48 are discharged into the reception chamber 21
through the nozzle hole 21a while widening the "+"-shaped cutting
line 48a, and the cosmetics discharged into the reception chamber
21 are applied by using the cosmetic tool 60.
[0078] The cosmetic tool 60 is formed of a general material such as
sponge, and a user can put on a makeup by applying the cosmetics
discharged into the reception chamber 21 through the nozzle hole
21a.
[0079] If the operation button 50 that has been pushed reversely is
released, the airless pump 40 and the tube container 30 that have
been moved forwards by a returning force of the compressed spring
43 as shown in FIG. 12D are operated in a reverse sequence to be
moved rearwards to the original location.
[0080] Then, as the engaging tube 41 of the airless pump 40 is
moved rearwards by a resilient force of the spring 43, the
operation cylinder 44 and the piston value 47 are also moved
rearwards to the original location. Accordingly, the piston value
47 closes a space between the piston support 46 and the inner wall
of the operation cylinder 44 that has been opened.
[0081] Thus, a strong vacuum pressure is applied to the compression
chamber 44a, and the cosmetics in the tube container 30 are
introduced into the compression chamber 44a to wait for the
following operation while the valve 45 installed in an inlet at an
end of the operation cylinder 44 is opened by a vacuum
pressure.
[0082] As the operation is repeated, the cosmetics in the tube
container 30 are discharged into the reception chamber 21 of the
reception body 20 to be used conveniently, and after the cosmetics
in the tube container 30 are completely used, the reception body 20
is separated from the case 10 so that the tube container 30 is
replaced by a new tube container 30 to refill cosmetics.
[0083] This is achieved by coupling the airless pump 40 and the
protection cap 32 to the tube container 30 to be assembled and
disassembled, and the entire structure in which the airless pump 40
and the protection cap 32 are coupled to the tube container 30 can
be replaced.
[0084] Meanwhile, the cosmetic container of the present invention
is a cosmetic container in which cosmetics are dedicatedly stored
in the tube container 30, but various medicines and detergents as
well as cosmetics may be stored in the tube container 30.
[0085] In particular, according to the present invention, since the
airless pump installed in the case may be operated horizontally
