Field of Invention
[0001] The present invention relates to a container for dispensing liquid cosmetics. It
particularly relates to a cosmetics compact which conveniently stores and dispenses
the liquid cosmetic product. The compact may also store other items such as an applicator
sponge or mirror.
Background of the Invention
[0002] Most cosmetic compacts contain cosmetic materials in solid, paste or powder form.
Compacts for applying more mobile liquid cosmetics are known, but can be cumbersome
to use. It can be particularly inconvenient when the liquid cosmetic is stored in
a container having a separate removable stopper or cap. This requires the user to
set aside or separately hold the stopper when using the compact. This can be messy
and inconvenient, as well as risking loss of the stopper.
[0003] JP2004208973 describes a cosmetic compact for dispensing a liquid cosmetic product without the
need to remove a separate stopper from the liquid cosmetic container, thus reducing
the possibility of staining a user's hands. The cosmetic compact comprises a main
body having an inner lid, an outer lid and a base connected by a hinge. The base of
the compact comprises a recess to contain a cosmetic puff and a further recess as
a reservoir for dispensed liquid cosmetics. The liquid cosmetic product is supplied
from a tubular container equipped with a pump-type dispenser. The outer lid is coupled
with the inner lid so as to enclose the tubular container. A pushbutton of the pump
type dispenser is exposed in an opening in the outer lid. On pressing the pushbutton,
the liquid cosmetic product is dispensed into the reservoir recess, for uptake on
the puff.
[0004] JP2004208975 describes an otherwise similar cosmetic compact in which the liquid cosmetic product
is automatically dispensed from the tubular container into the reservoir when the
lid is opened. Variants include a compact with a pump type dispenser having a nozzle
for dispensing the liquid product directly onto a hand held sponge. The nozzle has
a separate cover. In another variant, a squeeze-to-empty product container hinges
out of the base of the compact and has a dispensing passageway leading to an uptake
reservoir which also serves as a recess for storing a removable sponge.
[0005] Similarly,
GB0614449.7 (Toly Products Ltd) describes a cosmetic case for liquid products in which a stopper
for a liquid container is connected to the lid or base of the cosmetic case by a further
hinge.
[0006] With the continuing development of complex liquid cosmetic formulations, liquid cosmetics
can be chemically unstable and sensitive to air/oxygen making them difficult to package
and store for sufficient periods without deterioration. For example, small amounts
of microorganisms in the cosmetic material tend to flourish when exposed to an abundance
of air/oxygen to a point that they overwhelm the cosmetic formula's preservation system.
In another case, products such as skin bleaches and self tanners are very sensitive
to sunlight (ultra violet rays) causing unwanted discolouration to the product. As
the technology in cosmetics particularly in skin care products, forges ahead, sensitive
and fragile chemicals have been increasingly been used. Conventional cosmetic cases
for holding liquid cosmetics such as that described in
JP2004208973,
JP2004208975,
GB2434631 and also
US4343397 and
US6536447 do not provide an adequate oxygen barrier for many of the sensitive or fragile cosmetic
formulas.
[0007] Due to the sensitivity of such cosmetic formulas, air-tight or airless packaging
has increasing been used by cosmetic companies to prevent the influx of oxygen or
air into the cosmetic product during use. Conventional airless type containers described
in
FR2905681 (Rexam Dispensing Systems),
US2007164053 (Sik, S. D),
US6375045 (Hyun K, J) and
FR2868709 (Rexam Dispensing Systems) use a pump system and a piston inserted at the bottom
of a container or receptacle. During actuation of the pump system, air is taken in
through the bottom of the container through a one-way valve as the container evacuates
causing the piston to push the cosmetic material out from a dispenser. In
EP1226874 (L'Oreal), the container has a supple inner pouch to contain the cosmetic product to be dispensed
by an airless pump with a dip tube extending half way down the depth of the pouch.
An air space exists between the outer container and the inner supple pouch. During
actuation of the pump, air is taken through an inlet into the space. Thus atmospheric
pressure causes the inner pouch to compress and reduce in volume as material is exuded
from the pump. Although such systems provide a satisfactory airless dispensing system,
it still suffers from the disadvantage of the need to have a separate mechanically
operated pump to evacuate the contents of the container thereby complicating the manufacturing
of cosmetic containers containing such airless systems. Moreover, the design of such
airless systems would mean that incorporating them into a cosmetic case typically
having a lid hingedly connected to a base containing accessories of the usual kind
such as applicator sponge, puff, brush, mirror etc is made more difficult due to the
need to allow for the pump mechanism.
[0008] A similar arrangement is described in
FR2821766 (Airless Systems) comprising a rigid head with an outlet dispensing valve, a supple
inner pouch containing the cosmetic pouch and an outer compressible bulb with an air
inlet valve. The outer bulb is made from an elastomeric material and form an air space
around the inner pouch. The difference between this prior art and
EP1226874 (L'Oreal) is that instead of having an airless pump system and dip tube to dispense the product,
the inner pouch is compressed to expel the product when the outer bulb is squeezed
in the hand. When released, the bulb resumes its original shape by drawing in air
through the inlet valve. Thus the outer compressible bulb and the air inlet valve
serve as a kind of pump.
[0009] A cosmetic case for liquid cosmetics is needed incorporating an airless dispensing
system for sensitive cosmetic liquids and having the ability to contain accessories
of the usual kind such as applicator sponge, puff, brush, mirror etc and yet still
be easily assembled by conventional manufacturing techniques.
Summary of the Invention
[0010] Accordingly, the present invention provides a cosmetic compact having a lid hingedly
connected to a base, the compact further comprising a container housed in the base
to hold liquid cosmetics, in which the container comprises an inner container inside
an outer container so as to form an air space between the inner container and outer
container, the inner container being in fluid communication with a dispensing head
for dispensing the liquid cosmetic and the outer container comprising an air inlet
valve, wherein at least one wall of each the inner container and the outer container
is flexible so that in use when pressure is applied to the flexible wall of the outer
container, the flexible wall of the inner container deforms and expels a portion of
the liquid cosmetic characterised in that the flexible wall of the outer container
is accessible through a finger hole incorporated in the base of the compact.
[0011] Preferably the container for the liquid cosmetic is an airless container. This provides
the advantage of the ability to hold liquid cosmetics that are sensitive or fragile
to oxygen or air in a convenient cosmetic compact containing the necessary accessories
of the usual kind such as applicator sponge, puff, brush, mirror etc without the need
to hold/carry a separate container and accessory kit.
[0012] The cosmetic compact of the present invention removes the need of any rigid airless
pump mechanism connected to the container and incorporated in the cosmetic compact.
Such a rigid airless pump mechanism has the disadvantage of increasing the bulkiness
of the cosmetic compact and complicating the manufacture of the cosmetic compact.
In the present invention, the pump mechanism is provided by the user applying pressure
to at least one wall of the outer container.
[0013] Further preferred features and aspects of the invention will be apparent from the
dependent claims and the following description of an illustrative embodiment, made
with reference to the accompanying drawings.

the line X-X in Fig. 4.
Fig. 7 is a schematic cross-section through the cosmetic compact along the line IV-IV
in Fig. 3 when the lid is closed.
[0015] The cosmetic compact 1 shown in Fig. 1 comprises a lid 2 and a base 3 connected by
hinges 4. The hinges shown are held together by hinge pins 4a. The lid 2 comprises
a latch 5 to latch the lid closed against the base, which also can serve as a stopper,
as described in
GB2434361.
[0016] Figs 2 and 3 show cross-sectional views of the cosmetic compact on line 1-1 in Fig.
1, with the lid 2 open and closed respectively. The latch 5 is a flap connected to
the lid 2 by a hinge 6. The hinge 6 is shown as a thin flexible web integrally formed
with the lid 2. However, other means to connect the latch 5 to the lid 2 by means
of a hinge known in the art are permissible.
[0017] In the particular embodiment, the latch 5 is shown to comprise a protrusion which
cooperates with a dispensing orifice 8 formed in a container 9 housed in the base
3 of the cosmetic compact 1 or formed in a front wall of the lid or base. The protrusion
is shaped such that it either snugly fits into the orifice 8 in the front face of
the cosmetic compact 1 or is inserted into and held in the orifice 8 by a snap-in
arrangement.
[0018] The liquid cosmetic product is contained in the container 9 that can be squeezed
to expel the product through the orifice 8. As shown in Fig. 4, the container 9 is
an airless container comprising an inner container 21 for holding the liquid cosmetic
and sealed to a dispensing head 23 for dispensing the liquid cosmetic. The inner container
21 is arranged inside an outer container 20 which is also sealed to the dispensing
head 23. The dispensing head 23 is in fluid communication with the dispensing orifice
8 and comprises a one-way valve such as a slit type valve 23a so as to prevent the
intake of air or oxygen during and after expulsion of the liquid cosmetic. At least
one wall of each inner container 21 and the outer container 20 is flexible so as to
render them compressible. In another arrangement, the inner container 21 can be a
flexible walled pouch. The outer container 20 comprises an air inlet valve 20a (shown
as a simple flap valve. Alternatively, the air inlet valve may be a slit valve or
any other suitable form of valve). The inner container is plastically deformable,
e.g. formed as a supple pouch. In use, the user applies pressure to at least one flexible
wall of the outer container 20 which in turn closes the valve 20a and pressurises
the interior of the outer container 20. This in turn causes the inner container 21
to deform and reduce in volume causing liquid cosmetic to be dispensed from the dispensing
head 23. When the user releases pressure on the outer container 20, it resumes its
original shape and air is drawn in through the inlet valve. Thus the exterior flexible
wall of the inner container 21 is always is subjected to atmospheric pressure and
is placed under compression when the user squeezes the outer container 20.
[0019] The arrangement of the inner container 21 is such that in a maximum expanded configuration,
the inner container 21 is of substantially similar cross-section to the interior cross-section
of the outer container 20, i.e. the walls of the inner container 21 touch the inner
walls of the outer container 20. This provides maximum volume for containment of the
liquid cosmetic material by the inner container 21. Equally the height of the inner
container 21 can be substantially equal height to the outer container 20 such that
their ends touch. Figure 5 and 6 show examples of typical arrangements of the inner
container 21 shown in a particularly collapsed (discharged) condition inside the outer
container 20. In Figure 5, the inner container 21 is shown as a supple pouch having
a plurality of parallel fold lines normal to the page and the pouch is configured
as a star-shape in the cross section shown. In Figure 6, on the other hand, two of
the walls 21a, 21b of the inner container are collapsible, i.e. formed with a concertina
arrangement. Other arrangements of the inner container 21 are possible that provide
maximum volume in their expanded state and may also be capable of deforming substantially
symmetrically. In order to control the contraction or collapse of the inner container
21, a number of fixing points may be strategically positioned to the outer container
20 so as to define different shapes of contraction of the inner container 21. For
example, the inner container 21 may be fixed to the outer container 20 at three points
such that as the cosmetic material is exuded from the inner container 21, the inner
container 21 assumes a generally triangular shape before collapsing to a three-pointed
star shape. Moreover, the container 9 can assume a tubular shape but other shapes
are permitted that enables the container to snugly fit in the cosmetic compact 1.
[0020] However, the inner container 21 in its expanded state does not have to touch the
inner surface of the walls of the outer container 20 and a gap can exist between the
containers. In all cases, an air space 22 always exists between the inner container
21 and the outer container 20 as the inner container is discharged so as to allow
the proper function of the airless container. The inner and outer container 21 may
be made of thermoplastic material that is chemically inert and impermeable to air
or oxygen. Typical materials include polyethylene. Moreover, the inner 21 or outer
container 20 may limit or prevent the penetration of ultra violet (UV) light, which
could otherwise affect certain sensitive cosmetic materials.
[0021] The container 9 shown in Figure 7 comprises an assembly of the inner and outer containers
20 and 21 and substantially covers the entire floor area within the base 3. An upper
side wall of the container is therefore exposed for application of finger pressure
when the lid 2 of the compact 1 is opened. The container assembly 9 has a neck 10
terminating adjacent to the latch 5, to dispense the liquid cosmetic product. The
dispensing orifice 8 may be provided in a wider filling plug (not shown) sealingly
positioned within the neck 10. The container assembly 9 is held in the base 3 of the
cosmetic compact 1 by a snap-in arrangement 11 such that it can be detachably removed
from the cosmetic compact 1 when empty, or to substitute one liquid cosmetic product
for another. The snap-in arrangement 11 comprises a circumferential ridge 11a on the
neck of the container. The ridge 11a snaps into an internal recess in a collar 11b,
integrally moulded with or fixed to the base 3 adjacent the latch 5. Many other means
to secure the container assembly 9 in the base 3 of the cosmetic compact 1 known in
the art are permissible. For example, the container may be held in or beneath a secondary
housing or cover which fits in the recess in the base 3 of the cosmetic compact 1
by a snap-in arrangement. A finger access hole may be provided, allowing the upper
wall of the container assembly 9 to be squeezed to dispense the cosmetic material.
[0022] Alternatively, the container assembly 9 may be permanently held in the base 3 of
the cosmetic compact 1 or form part of the base 3. This simplifies the manufacturing
process and hence further reduces costs of manufacture. For example the base 3 of
the cosmetic compact 1 can be integrally moulded with the container assembly 9 by
way of insert moulding. Alternatively, the container assembly 9 can be held in the
base 3 by adhesive, ultrasonic welding, or the like. The entire compact may be disposed
of and recycled when the container 9 is empty.
[0023] The lid 2 and the base 3 of the cosmetic compact 1 can be separately moulded from
a single material, for example, injection moulded relatively rigid plastics resin.
For ease of manufacture it is preferable that the stopper 5 is integrally moulded
with the lid 2.
[0024] When the lid 2 is in the closed position as shown in Fig. 3, the latch 5 is shown
with its protrusion 7 inserted into the orifice 8 of the container assembly 9 in the
base 3 of the cosmetic compact 1. The lid 2 is opened by simply pivoting the latch
5 about its hinge 6 such that the protrusion 7 is withdrawn from the orifice 8. The
lid 2 is now able to rotate about the hinges 4 to the open position as shown in Fig.
2. The contents of the container assembly 9 can then be dispensed by pressing on or
squeezing the outer container 20. This causes the liquid cosmetic product to be expelled
from the orifice 8. As well as squeezing the upper wall of the container assembly
9, a finger hole 14 incorporated in the underside of the base 3 of the cosmetic compact
1 provides a means to squeeze the container assembly from underneath. A cosmetic applicator
13 such as a puff, sponge, etc can be stored in the cosmetic compact 1 above the container
9, as shown in Figs 2 and 3. In addition, a mirror 12 can attached to the underside
of the lid 2 as shown in Figs 2 and 3.
[0025] An advantage of this arrangement over conventional cosmetic compacts for dispensing
a liquid cosmetic product is the provision of an airless container for dispensing
liquid cosmetics and the ability to open the lid of the cosmetic compact and the container
holding the liquid cosmetic product without needing to provide a separate stopper
or cap to the container; the whole being simple to manufacture, having few components.
This further provides the ability to compactly combine liquid cosmetic product with
an applicator used to apply the liquid product.
[0026] The stopper 5 is in fact optional, and therefore can be dispensed with. In that case,
any suitable conventional releasable latch mechanism can be used to secure the lid
and base closed.
