Description
FIELD OF THE INVENTION
[0001] The present invention relates to a beauty care product
comprising a sealable plastic container, a sealing means and a
beauty care component; to a kit comprising said product thereof; to
a method of manufacturing said product; and to a method of using
said product for application onto skin and/or hair. The present
invention provides a product, the container of which is resistant
to random, uncontrolled deformation under a substantial pressure
differential between the environment and inside the container, yet
having an affordable cost of manufacture and/or being appealing to
the consumer.
BACKGROUND OF THE INVENTION
[0002] Beauty care compositions, particularly hair coloring and/or
bleaching compositions and/or heat-generating cosmetic
compositions, may involve reactive chemistry, as they comprise
ingredients undergoing a chemical reaction when placed in contact
with each other. For example, oxidative hair color compositions
comprise a primary precursor (also called coupler), a secondary
precursor (also called developer) and an oxidizing agent such as
ammonia. When mixed together, a chemical reaction occurs so that a
dye is formed.
[0003] Such chemical reaction is wanted upon application onto hair,
but not before. For avoiding the chemical reaction to occur
prematurely such as upon manufacture and/or upon storage, these
ingredients are usually comprised within different components, such
as a first component (also called a tint) comprising the primary
precursor and a second component (also called the developer)
comprising the secondary precursor. These components may be sold as
a kit and be packaged individually in any suitable packaging,
wherein these kits comprise at least two components to be mixed
extemporaneously i.e. shortly before application onto hair.
[0004] Professional hairdressers are usually mixing the different
components using a bowl and a spatula. Untrained users such as
consumers coloring their hair by themselves are not willing to mix
the components in a bowl, as the mixture obtained may lack
homogeneity, leading afterwards to an uneven hair coloration and
also because such process is uneasy to achieve, and may lead to
staining the area where the mixing is taking place e.g. the sink,
the bathtub, and/or the floor.
[0005] For avoiding such drawbacks, hair coloring and/or bleaching
kits are usually provided with at least one squeezable plastic
container comprising about 70% or less of a component upon storage.
At least one of the other components is poured into the container,
mixed together with its content, and the resulting hair coloring
and/or bleaching composition is applied onto hair by squeezing the
plastic container.
[0006] Such type of containers while being convenient upon use,
have shown drawbacks upon storage. Indeed, they usually comprise
relatively thin panels in order to be squeezable i.e. deformable
upon application of localized pressure onto the container by hand
without excessive force. However, as these containers are filled
with about 70% or less of a component, there is a substantial
residual volume filled with gas e.g. ambient air at the place of
manufacture. Upon certain circumstances such as a change of
temperature and/or a change of altitude, there may have a
significant pressure differential between the environment and
inside the container. Such differential often leads to an
uncontrolled, random deformation of the container. This is unwanted
as the container may not be appealing to the consumer, may look
defect and/or may even induce the leaking of its content and/or its
breakage.
[0007] Different solutions have been provided for avoiding these
drawbacks. For example, containers comprising thicker labels and/or
labels made of more rigid plastics have been provided. These
containers require however an increased force for being squeezed,
which is inconvenient upon use by the consumer. Containers having
pressure-regulating means have also been provided. Such means are
usually sophisticated and therefore expensive to be manufactured.
It also usually requires at least one additional process step for
affixing them onto the container and/or the sealing means. This
drives the cost of manufacture up, and impacts negatively on the
price of sale of the hair coloring and/or bleaching products and/or
kits.
[0008] There is a desirable need therefore of providing a hair
coloring and/or bleaching product comprising a squeezable plastic
container containing upon storage about 70% or less of a hair
coloring and/or bleaching component, which is resistant to random,
uncontrolled deformation under a substantial pressure differential
between the environment and inside the container. There is also the
desirable need for providing a hair coloring and/or bleaching
product comprising a squeezable plastic container being resistant
to uncontrolled deformation, which has an affordable cost of
manufacture. There is also the desirable need for providing a hair
coloring and/or bleaching product comprising a squeezable plastic
container being resistant to uncontrolled deformation, which is
appealing to the consumer yet easy to use.

label being the label displaying information about the product to
be seen first by the consumer when standing on the supermarket
shelf, including, but not limited to, the brand name, logo, slogan,
illustrations and/or pictures, information such as the container
size, etc.
[0033] As a used herein, "beauty care products" means any products
being suitable for application onto keratin substrates, including
hair, skin, eyebrows, eyelashes, lips, and nails. Beauty care
products may include personal care products, make-up products,
shave care products and hair care products. Personal care products

products may include mascaras, foundations and enamels. Hair care
products may include shampoos, conditioning compositions, styling
compositions and hair color compositions.
[0034] In a first aspect, the present invention relates to a
product comprising a sealable plastic container 1, said container 1
comprising a base section 2, a body section 3, and a neck section
4. The base section 2 allows the container 1 to rest onto a
surface, e.g. a supermarket shelf and/or on the bathtub or sink
contours. The neck section 4 forms an aperture 5, suitable for
pouring a liquid into and/or out of the container 1. The container
1 may also contain a shoulder section 6, joining the body section 3
to the neck section 4.
[0035] The base section 2, the body section 3, the neck section 4,
and optionally the shoulder section 6 delimit an inner reservoir
(not shown). This reservoir comprises a total volume of from about
20 ml to about 1500 ml, alternatively from about 50 ml to about
1000 ml, alternatively from about 75 ml to about 500 ml,
alternatively from about 100 ml to about 250 ml, alternatively from
about 160 ml to about 170 ml.
[0036] A beauty care component (not shown), particularly a hair
coloring and/or bleaching component, as described hereinafter, is
contained within the reservoir. The reservoir comprises upon
storage no more than about 70%, no more than about 50%,
alternatively from about 30% to about 50%, of said component by
total volume of the reservoir. In another embodiment, the reservoir
comprises upon storage less than about 30% and/or at least about 5%
of said component by total volume of the reservoir. In still
another embodiment, the reservoir (container) is substantially free
of any component upon storage.
[0037] After filling and sealing, as the inner reservoir is not
filled entirely with said component, the reservoir is left with a
remaining volume. In a preferred embodiment, said remaining volume
is filled with a gas. The gas may be selected from oxygen,
nitrogen, carbon dioxide, ambient air, and mixtures thereof;
alternatively a gas being ambient air; alternatively a gas being
ambient air at a pressure from about 70 kPa to about 101 kPa;
alternatively a gas being ambient air at a pressure from about 70
kPa to about 101 kPa and at temperature of from about 15.degree. C.
to about 45.degree. C. In at least one embodiment, the remaining
volume of the reservoir is filled with ambient air. As used herein,
"ambient air" means the ambient air at the time of manufacture of
the product, particularly the time at which the container 1 is
filled with the component, and subsequently sealed. Without wishing
to be bound by any theory, it is believed that, because the
reservoir of the container 1 comprises upon manufacture and/or
storage a remaining volume filled with a gas at a certain pressure
and temperature, this container 1 may be subject to deformation
forces, such as extension and/or collapsible forces, whenever a
substantial pressure differential between the environment and the
reservoir remaining volume occurs. As used herein. "a substantial
pressure differential" means a difference of pressure of from about
0.01 kPa to about 30 kPa between the environment and the reservoir
remaining volume. Such pressure differential may be induced by a
change of temperature inside the reservoir and/or a change of
atmospheric pressure in the environment, e.g. because of a change
of altitude.
[0038] The body section 3 is four-panelled. It comprises a front
panel 7, a back panel 8, and two side panels 9 and 9a. These panels
are substantially vertical.
[0039] The front and back panels 7,8 are non-collapsible and
squeezable panels. As used herein, "non-collapsible" means that
these panels are not prone to a passive deformation when the
container 1 is subject to a substantial pressure differential. As
used herein, "squeezable" means that these panels are prone to an
active deformation when subject to a substantial force e.g. a force
of at least 0.113 Joules (1 in-lb), alternatively from about 0.113
Joules (1 in-lb) to about 4.519 Joules (40 in-lb), alternatively
from about 1.130 Joules (10 in-lb) to about 3.390 Joules (30
in-lb), exerted locally onto these panels, preferably a force
exerted by the consumer hand. At least one of the front and back
panels 7,8 may be functional panels, alternatively the front panel
7 may be a functional panel or both panels 7 and 8 may be
functional panels. As used herein, "functional" means that the
panels are the support for the labels, comprising various
information including, but not limited to, the brand name, logo,
slogan, illustrations and/or pictures, information such as the
container size, ingredient list, and/or regulatory requirements.
The front and/or the back panels 7/8 may have an average thickness
of from about 0.50 mm to about 3 mm, alternatively from about 0.50
mm to about 1.5 mm, alternatively from about 0.55 mm to about 1.15
mm. The front and back panels 7,8 may have substantially the same
average thickness, alternatively an average thickness differing
from about +/-10%, alternatively from about +/-5%, alternatively
from about +/-1%.
[0040] Thickness can be measured using a caliper device. Average
thickness may be measured by taking at least 10 measurements
approximately evenly distributed across the area of the panel and
then calculating the mean thickness i.e. average thickness, which
is measured in millimetres i.e. mm. In at least one embodiment, the
average thickness has a standard deviation of less than about
+/-10%, or less than about +/-5%, or less than about +/-1%.
[0041] The side panels 9 and 9a are collapsible panels. As used
herein, "collapsible" means that these panels are prone to a
passive deformation when the container is subject to a substantial
pressure differential. In at least one embodiment, "substantial
pressure differential" means a pressure differential of at least
2%, or at least 5%, or at least 10%, or at least 20% measured in
kPa. Preferably, the side panels 9 and 9a are collapsible
substantially over their entire surface. In a preferred embodiment,
these panels are not intended to be squeezable/squeezed. These
panels may be non-functional panels, i.e. these panels may not be
the support of any label. The side panels 9 and 9a may have an
average thickness of from about 0.25 mm to about 1.5 mm,
alternatively from about 0.25 mm to about 0.55 mm. Both side panels
9 and 9a may have substantially the same average thickness,
alternatively an average thickness differing from about +/-10%,
alternatively from about +/-5%, alternatively from about +/-1%.
[0042] In order for the front and back labels 7,8 and the side
labels 9,9a to exhibit different properties vis-a-vis
collapsibility and squeezability under normal conditions of use,
and particularly for obtaining a container having non-collapsible,
squeezable front and back panels 7,8 and collapsible side panels
9,9a, the inventors have found that these panels should exhibit a
specific differential of average thicknesses. The ratio of the
average thicknesses between the front and/or back panels 7,8 and
the side panels 9,9a is at least about 2:1, alternatively from
about 2:1 to about 5:1, alternatively from about 2:1 to about 3:1,
alternatively from about 2:1 to about 2.5:1. Average thickness is
measured in millimetres i.e. mm, and thus the ratio of average
thickness refers to mm.
[0043] In at least one embodiment, the body section 3 is an
extended hollow body section. In a preferred embodiment, the body
section 3 has a non-cylindrical, non-rectangular and non-squared
cross-sectional shape (horizontal cross-section at half height).
The body section 3 may have an overall elliptical cross-sectional
shape, with the tangents at the panel edges between the side panel
9,9a and the front and/or the back panels 7,8 forming an angle of
more than 90.degree. and less than 180.degree., alternatively from
about 100.degree. to about 150.degree., alternatively from about
110.degree. to about 140.degree..
[0044] In at least one embodiment, the front and/or back panels 7,8
are substantially non-planar relative to a horizontal plane,
preferably they are substantially convex in shape relative to a
horizontal plane. The front and/or back panels 7,8 may have a
radius from about 10 mm to about 40 mm, alternatively from about 10
mm to less than about 20 mm, alternatively from about 20 mm to less
than about 30 mm, alternatively from about 30 mm to about 40 mm.
The front and/or back panels 7,8 may also be substantially planar
relative to a vertical plane.
[0045] In at least one embodiment, the side panels 9,9a are
substantially non-planar relative to a horizontal plane, preferably
they are substantially concave in shape relative to a horizontal
plane. The side panels 9,9a may have a radius from about 10 mm to
about 55 mm, alternatively from about 10 mm to less than about 20
mm, alternatively from about 20 mm to less than about 30 mm,
alternatively from about 40 mm to less than about 55 mm. The side
panels 9,9a may also be substantially planar relative to a vertical
plane.
[0046] In at least one embodiment, the sealable plastic container 1
has a substantially symmetrical shape relative to an axis formed by
the center of the aperture and the center of the bottom base
section 2.
[0047] The container 1 may have a width of from about 20 mm to
about 105 mm, alternatively from about 20 mm to about 30 mm,
alternatively from about 40 mm to about 50 mm, alternatively from
about 90 mm to less than about 105 mm. In at least one embodiment,
the width is the average width. Average width may be measured by
taking at least 10 measurements approximately evenly distributed
across and then calculating the mean width i.e. average width,
which is measured in millimetres i.e. mm. In at least one
embodiment, the average width has a standard deviation of less than
about +/-10%, or less than about +/-5%, or less than about
+/-1%.
[0048] The container 1 may also have a length of from about 20 mm
to 80 mm, alternatively from about 20 mm to about 30 mm,
alternatively from about 40 mm to about 50 mm, alternatively from
about 70 mm to about 80 mm. In at least one embodiment, the length
is the average length. Average length may be measured by taking at
least 10 measurements approximately evenly distributed across and
then calculating the mean length i.e. average length, which is
measured in millimetres i.e. mm. In at least one embodiment, the
average length has a standard deviation of less than about +/-10%,
or less than about +/-5%, or less than about +/-1%.

Example
[0063] The following examples are for illustration and not intended
to limit the claim scope.
[0064] A beauty care product according to the present invention was
obtained starting from a commercially available high-density
polyethylene (HDPE) provided by Exxon under the tradename AS55-003
and using an extrusion blow molding process.
[0065] The sealable plastic container 1 obtained--as shown in FIG.
1--exhibits the following characteristics:
[0066] weight (undecorated): 12.0 g+/-1.5 g;
[0067] height (overall): 114.45 mm+/-1.52 mm:
[0068] width (max): 51 mm+/-1.52 mm;
[0069] depth (max): 44.5 mm+/-0.4 mm;
[0070] overflow capacity (OFC): 165 mL+/-5 mL;
[0071] side panels thickness (average): 0.39 mm
[0072] front panel thickness (average): 1.04 mm
[0073] back panel thickness (average): 1.04 mm
[0074] difference in wall thickness between front and back panel
(measured at the center): 0.0 mm+/-0.1 mm;
[0075] difference in wall thickness between two symmetrical side
panels (measured at the center): 0.0 mm+/-0.1 mm;
[0076] ratio of the average thicknesses between front and/or back
panels and the side panels: 2.67 mm total volume of the inner
reservoir: 165 ml
[0077] I dimension (inner diameter of the neck section): 17.02
mm+/-0.12 mm:
[0078] T dimension (outside diameter of the neck section): 23.66
mm+/-0.2 mm;
[0079] H dimension (height of the neck section) 12.34 mm+/-0.4
mm;
[0080] The sealing means is non-vented closure to be screwed onto
the screw thread of the neck section of the container.
[0081] The beauty care component is a developer component,
conventionally used in the field of hair coloring and/or bleaching
hair. This developer is Welloxon 6%. The volume of the developer
packaged into the container is of about 60 ml, i.e. about 36% of
the total volume of the inner reservoir of the container. The
remaining volume filled with ambient air at the place of
manufacture is therefore of about 64% of the total volume of the
inner reservoir.
[0082] The beauty care product is manufactured at a place of
manufacture wherein the ambient temperature is about 21.degree. C.
to about 26.degree. C. and the atmospheric pressure is about 80 kPa
to about 84 kPa.
[0083] Upon transportation and/or storage, despite some changes of
ambient temperature and/or atmospheric pressure, the container
shows satisfactory resistance to random, uncontrolled deformation
because of the presence of two symmetrical collapsible side panels
having a specific average thickness ratio relative to the front
and/or back panels.
[0084] The dimensions and values disclosed herein are not to be
understood as being strictly limited to the exact numerical values
recited. Instead, unless otherwise specified, each such dimension
is intended to mean both the recited value and a functionally
equivalent range surrounding that value. For example, a dimension
disclosed as "40 mm" is intended to mean "about 40 mm." Every
document cited herein, including any cross referenced or related
patent or application and any patent application or patent to which
this application claims priority or benefit thereof, is hereby
incorporated herein by reference in its entirety unless expressly
excluded or otherwise limited. The citation of any document is not
an admission that it is prior art with respect to any invention
disclosed or claimed herein or that it alone, or in any combination
with any other reference or references, teaches, suggests or
