[0003] A COSMETIC APPLICATOR

[0004] This invention relates to a cosmetic applicator and more particularly to a cosmetic applicator for applying a tanning composition, as well as methods of using the applicator to apply cosmetic compositions.

[0005] Background of the Invention

[0006] Numerous applicators are known for applying cosmetic compositions, such as tanning compositions. For example, many different types of brushes and sponges are available including different-shaped brushes, double-ended brushes, powder puffs and beauty blenders.

[0007] These types of applicators are typically a standalone product, purchased in addition to the cosmetic composition. As such, cosmetic compositions are generally packaged without an applicator, for example in a bottle (e.g. a pump bottle), a tube or a jar. In use, an effective amount of the cosmetic composition is typically dispensed or deposited from the bottle or tube or jar, for example onto the back of the user’s hand, before being applied (e.g. to the face). The user then typically requires one or more applicators to apply and blend out the cosmetic composition.

[0008] For some cosmetic products, the cosmetic composition is packaged with a built-in applicator. However, a common problem with these products is the build-up of residue on the applicator, which can be difficult to properly clean without spoiling the cosmetic composition and is often permanently connected to the applicator. This is a particularly common problem for products containing tanning compositions because the tanning agent in the composition will generally oxidise when exposed to air, causing discolouration of the applicator if left uncleaned.

[0009] Cosmetic compositions with built-in applicators are also generally more expensive, since they are marketed as a two-in-one product. This can mean that they are not economical in the long term because when the cosmetic composition runs out, the user is forced to replace both the composition and the applicator, since the applicator is built-in to the packaging of the composition. From an environmental point of view, this is also not ideal, as the entire applicator is disposed of once the composition has been used up, even if the applicator (or at least a part of the applicator) could be reused. P41814W0

[0010] 2

[0011] As mentioned above, when applying a cosmetic composition, the user typically requires more than one type of applicator, for example one to apply the product and one to blend it out. Known cosmetic compositions with built-in applicators only comprise one type of applicator, so do not meet this requirement.

[0012] As such, there exists a need for an improved applicator for applying cosmetic compositions, in particular tanning compositions, to the face and body which do not suffer from the disadvantages noted above.

[0013] The Invention

[0014] The present invention provides a cosmetic applicator for applying (and blending) a cosmetic composition, such as a tanning composition.

[0015] Accordingly, in a first aspect, the invention provides an applicator for applying a cosmetic composition wherein the applicator comprises:

[0016] (i) a body having a first end and a second end, the body comprising a hollow cavity defining a reservoir in which the cosmetic composition may be stored, wherein the cavity is open at the first end of the body;

[0017] (ii) an applicator head connected to the first end of the body; and

[0018] (iii) a brush removably connected to the second end of the body;

[0019] wherein the cosmetic composition can be applied from the reservoir via the applicator head.

[0020] The applicator head typically comprises a sponge or a brush for applying the cosmetic composition onto the skin, face or body. For example, the applicator head may comprise a sponge. Alternatively, the applicator head may comprise a brush. Preferably, the applicator head does not comprise a pen or felt tip type applicator, for example having a nib and a wick. The applicator head typically has an open passage (or hole I aperture) through which the cosmetic composition can pass, with the brush or sponge covering one end of the open passage. Suitably, at least a portion of the brush or sponge protrudes out of an open end of the applicator head.

[0021] When the applicator head comprises a sponge, the sponge is typically made from a porous material, such as foam, for example polyurethane foam. Alternatively, the P41814W0

[0022] 3

[0023] sponge can be made from a non-porous material, such as silicone, comprising (small) perforations to allow the cosmetic composition to pass through. The sponge is typically flexible and / or, when pressed, reverts back into its original shape when the compression force is released. The sponge may be substantially circular or semicircular in shape and / or it may have a rounded or pointed tip. Alternatively, the sponge may be substantially square or rectangular in shape. When the sponge is substantially square or rectangular in shape it may be flat or angled. The shape and / or density of the sponge may vary depending on the cosmetic composition used in the applicator. Preferably, the sponge is substantially circular or semicircular in shape and has a rounded tip.

[0024] Alternatively, the applicator head may comprise an applicator brush instead of a sponge. Accordingly, the applicator may comprise two brushes, one at either end of the body. When the applicator head comprises a brush, there is still an aperture in the applicator head which allows the cosmetic composition to be dispensed from the reservoir to the brush (i.e. via the aperture) to allow the cosmetic composition to be applied to the skin / face / body using the brush as a means for applying it. The brushes may be the same shape and / or texture or different shapes and / or textures. For example, the brush at the first end of the body (in the applicator head) may be of suitable shape and / or texture for applying the cosmetic composition to the skin or face or body, while the brush at the second end of the body may be of suitable shape and / or texture for blending out the cosmetic composition once applied.

[0025] The applicator may be provided with a first removable lid on the first end, which covers the applicator head when attached to the applicator. It will be appreciated that the first removable lid protects the applicator head and also prevents the cosmetic composition coming into contact with other items when the applicator is stored (e.g. in a user’s bag, such as a handbag). Preferably, the first removable lid is a cone shape with a pointed closed end. Alternatively, the first removable lid may be a cylindrical shape having a rounded or pointed or flat or angled closed end. The first removable lid may connect to the applicator head or the body, preferably the body, via a friction-fit mechanism, click-fit mechanism or a screw fit mechanism, preferably via a friction-fit mechanism.

[0026] The brush which is removably connected to the second end of the body and / or the brush comprised within the applicator head, when the applicator head comprises a brush, typically comprises a handle portion and bristles for blending out the P41814W0

[0027] 4

[0028] cosmetic composition (once applied to the skin or face or body using the sponge). One end of the handle portion may be removably connectable to the body of the applicator and the other end of the handle may house the bristles. The handle portion of the brush may be removably connected to the first or second end of the body by a screw-fit or a click-fit mechanism. Accordingly, the handle may comprise an internal screw portion (e.g. a female screw thread), which suitably connects to a corresponding threaded screw portion (e.g. a male screw thread) at the first or second end of the body of the applicator. The handle may also comprise a protruding portion, which protrudes out of the screw portion, away from the body of the applicator. The protruding portion may house the bristles.

[0029] The bristles on the brush which is removably connected to the second end of the body and / or the brush comprised within the applicator head, when the applicator head comprises a brush, are typically made from a synthetic material. They may be as a 5mm or longer, or 10mm or longer in length and / or up to 25mm, or up to 20mm, or up to 15mm in length. For example, they may be between 5mm and 25mm, or between 5mm and 20mm, or between 10mm and 15mm in length. The bristles may all be of equal lengths, for example the brush may be a flat brush. Alternatively, the bristles may vary in length, for example the brush may be angled, or rounded, or pointed. Preferably, the brush is angled (i.e. the bristles on one side of the brush are longer than those on the other side). The bristles may be densely packed, such that the brush has a firm and / or dense texture or, alternatively, them may be less densely packed (or loosely packed), such that the brush has a fine and / or fluffy texture. The shape and / or texture of the brush I bristles may vary depending on the cosmetic composition used in the applicator. Preferably, the bristles are densely packed and angled.

[0030] The applicator may be provided with a second removable lid on the second end, which covers the brush when attached to the applicator. The second removable lid may be connected to the second end of the body via a friction-fit, click-fit or a screw-fit mechanism. Preferably, the second removable lid is a cylindrical shape having a flat closed end, so that the applicator can be stood I balanced in an upright position on the flat end of the second removable lid (with the brush end pointing downwards and the applicator head end point upwards). Alternatively, the second removable lid may be a cylindrical shape with a rounded or pointed or angled closed end, or even a cone shape with a pointed closed end. P41814W0

[0031] 5

[0032] The first and / or second lid may comprise a compartment for storing a further cosmetic composition. For example, the further cosmetic composition may be a blusher, lip balm, moisturiser, bronzer or concealer. In this embodiment, the invention provides a convenient means for a user to carry around two cosmetic products in the same applicator. The further cosmetic composition may be accessed through the end of the first or second lid which is not removably connectable to the applicator head or brush, respectively. For example, the first and / or second lid may comprise a recess on its terminal end (i.e. the end not attached to the applicator body). The further cosmetic composition can then be stored within this recess with an additional lid being provided, which may attach to the first / second lid in order to close the recess.

[0033] The hollow cavity in the body of the applicator may be closed at the second end of the body (i.e. the end of the body at which the brush is removably connected). Accordingly, the cosmetic composition may only be able to exit the reservoir through the open first end of the body (via the applicator head), not through the second end. Suitably, there is only one hollow cavity in the body of the applicator (having only one open end, i.e. the first end). Preferably, the brush is not in direct contact or communication with the reservoir or the cosmetic composition stored therein (for example, because the hollow cavity is closed at the second end).

[0034] The hollow cavity in the body of the applicator may have a movable base, which can be moved to increase or decrease the volume (e.g. the height) of the reservoir. By decreasing the volume of the reservoir, the cosmetic composition is forced out of the aperture in the applicator head to allow it to be applied by the user.

[0035] Alternatively, the cosmetic composition dispensed into the applicator head by some other mechanism. For example, the sidewalls of the body may be made of a flexible material and the volume in the hollow cavity I reservoir may be decreased by applying pressure (e.g. by squeezing) to the sidewalls of the body.

[0036] The movement of the movable base may be controlled by a twist dial. For example, there may be a twist dial for moving the cavity base and thereby changing the volume of the reservoir. The movable base in the cavity may be provided with a threaded stem extending inside the body away from the reservoir. The threaded stem may engage with the twist dial, such that rotation of the twist dial results in a lateral movement of the movable base in order to increase / decrease the cavity volume. The twist dial may be positioned between the P41814W0

[0037] 6

[0038] second end of the hollow cavity (i.e. where the movable base is) and the brush. In use, the twist dial may be twisted in one direction (e.g. anticlockwise) to move the cavity base away from the brush (and / or towards the applicator head) to decrease the volume of the cavity. Optionally, the twist dial may also be twisted in the other direction (e.g. clockwise) to move the cavity base towards the brush (and / or away from the applicator head) to increase the volume of the cavity. Alternatively, the twist dial may only be twistable in a single direction (e.g. anticlockwise) to decrease the volume of the cavity. Preferably, the twist dial is only twistable in a single direction (e.g. anticlockwise).

[0039] The applicator head and / or the brush may be connected to the body of the applicator via a friction-fit mechanism, click-fit mechanism or a screw fit mechanism, preferably via a screw-fit mechanism. When the brush connects to the body of the applicator via a screw-fit mechanism and the hollow cavity in the body of the applicator has a movable base which is controlled by a twist dial, the screw-fit mechanism is preferably threaded in the opposite direction to that of the twist dial. Accordingly, it is preferred that the user twists the twist dial in a first direction (e.g. anticlockwise when the user is looking in a direction towards the second of the body) to move the movable base of the hollow cavity upwards and twists the screw-fit mechanism in a second, opposite direction (e.g. clockwise when the user is looking in a direction towards the second of the body) to remove the brush. This feature is preferred because it accommodates easy movement of the base of the hollow cavity without accidental removal of the brush and, vice versa, it accommodates easy removal of the brush without accidental movement of the base of the hollow cavity. The risk of spillages of the cosmetic composition stored in the reservoir, by accidental upwards movement of the base of the hollow cavity, is therefore reduced.

[0040] Similarly, for other (adjacent) component parts of the applicator which are both connected to the (body of) the applicator via a screw-fit or twist dial mechanism, it is preferred that the mechanisms are threaded in opposite directions and / or that the user is required to twist each component part in an opposite direction to remove or move it. This is preferred, for example, so that removal or movement of one component part does not accidentally lead to removal or movement of another (adjacent) component part. P41814W0

[0041] 7

[0042] Preferably, the cosmetic composition is a tanning composition, for example to apply (semi-permanent) contour to the skin, face or body. However, the applicator is also suitable for use with other types of cosmetic composition. For example, the cosmetic composition may be a blusher, a foundation, a concealer, a highlighter, or a bronzer. Typically, the cosmetic composition is a foundation, blusher or contour (for applying to the face). Suitably, the cosmetic composition is a make-up composition (for applying to the face). More suitably, the cosmetic composition is a semi-permanent make up composition which is capable of reacting with human skin. Typically, cosmetic composition reacts with human skin to provide a more pigmented appearance or a change in the colouration of the skin. The more pigmented appearance may be a more tanned or bronzed appearance, in the case of tanning compositions. Alternatively, it may be a more tinted (e.g. rosy) appearance, for example in the case of blushers and compositions which contain blusher. Alternatively, it may be a lighter or brighter appearance, for example in the case of concealers or highlighters, or compositions containing concealer or highlighter. Suitably, the cosmetic composition is a liquid (or a gel) composition. Preferably, the cosmetic composition is not a composition for applying to the nails, such as a nail care product. For example, the cosmetic composition is preferably not a nail varnish I polish, a nail varnish I polish remover and a nail I cuticle oil. Preferably the (make-up) cosmetic composition is not a composition for applying to the eyebrows (or hair). For example, the cosmetic composition is preferably not an eyebrow powder, tint or dye.

[0043] Suitably, the cosmetic composition comprises:

[0044] (i) at least one tanning component capable of reacting with human skin to provide a more tanned appearance; and

[0045] (ii) a dermatologically acceptable carrier.

[0046] References herein to percentages by weight (w / w) refer to the percentage weight relative to the total weight of the composition, unless indicated to the contrary.

[0047] The term “tanning” as used herein refers to the process of changing the colouration of skin so that it has a more tanned or highly coloured appearance. The tanning component is capable of reacting with human skin to provide a more tanned appearance. The term “capable of reacting with human skin” is used in a general sense to include components that undergo a chemical reaction in the skin to P41814W0

[0048] 8

[0049] produce a tanning colour, as well as components that act simply as dyes, and components that stimulate the development of natural skin pigments.

[0050] Thus, the cosmetic composition may bring about the process of colouration of the skin by one or more mechanisms. For example, the cosmetic composition can contain components that stimulate the activity of melanocytes in the skin so as to bring about more rapid production of melanin. This effect can be achieved, for example, by the use of a combination of hexose sugar and beta-glucan.

[0051] Alternatively, or additionally, the cosmetic composition can contain a hydroxyketone component which reacts with amino acids in the protein keratin in the skin in a Maillard reaction to give brown pigments known as melanoidins. The melanoidins are similar in colour to melanin.

[0052] Accordingly, the at least one tanning component capable of reacting with human skin to provide a more tanned appearance may be selected from:

[0053] (a) a polyhydroxy-ketone which is capable of undergoing a Maillard reaction with amino acids in skin keratin to produce a melanoidin; and (b) a substance that stimulates the production of melanin by melanocytes when applied to the skin;

[0054] and mixtures thereof.

[0055] The polyhydroxy-ketone may be selected from:

[0056] (a) dihydroxyacetone;

[0057] (b) erythrulose; and

[0058] (c) a mixture of dihydroxyacetone and erythrulose.

[0059] Preferably, the polyhydroxy-ketone is or comprises dihydroxyacetone. Optionally, the polyhydroxy-ketone comprises dihydroxyacetone and erythrulose. The polyhydroxy-ketone is typically present in an amount of at least 3% (w / w) of the composition, or at least 5%, or at least 8% and / or in an amount of up to 25% (w / w) of the composition, or up to 20%, or up to 18%, or up to 15%. The erythrulose, when present, is typically present in an amount of at least 1% (w / w) of the composition, or at least 2%, or at least 3% and / or up to 15% (w / w) of the composition, or up to 10%, or up to 5%. P41814W0

[0060] 9

[0061] For example, the polyhydroxy-ketone may be present in an amount from 3% to 25% (w / w) of the composition, and more usually from about 5% to about 20%. When the polyhydroxy-ketone is a mixture of dihydroxyacetone and erythrulose, the dihydroxyacetone may be present in an amount of from 5% to 18% (w / w), for example from 5% to 15% (w / w) or from 8% to 15% (w / w), of the tanning composition and / or the erythrulose may be present in an amount of from 1% to 5% (w / w) of the tanning composition.

[0062] Substances that stimulate the production of melanin by melanocytes when applied to the skin include 7-palmitoyl-5-hydroxy-2-methylchromone, and combinations of at least one aldo-hexose sugar and beta-glucan; and mixtures thereof. Suitably, the substance that stimulates the production of melanin by melanocytes when applied to the skin is or comprises 7-palmitoyl-5-hydroxy-2-methylchromone.

[0063] Alternatively, the substance that stimulates the production of melanin by melanocytes when applied to the skin is a combination of at least one aldo-hexose sugar and beta-glucan; and mixtures thereof. The aldo-hexose sugar may be selected from any of the sixteen naturally occurring aldo-hexose sugars but, more usually, is selected from mannose and glucose. Preferably, the compositions contain mannose. More usually, the compositions contain both mannose and glucose.

[0064] The total amount of aldohexose sugar present is typically an amount of no more than 1% (w / w) and more typically no more than 0.5% (w / w). For example, the total amount of aldo-hexose sugar may be up to 0.2 % (w / w). The beta-glucan can be present in the compositions of the invention in amounts of up to about 0.5% (w / w), more usually up to about 0.2% (w / w), for example up to about 0.1% (w / w).

[0065] The dermatologically acceptable carrier (ii) (which may also be referred to as a vehicle) is usually an aqueous carrier. The dermatologically acceptable carrier may constitute at least 60% (w / w) of the composition, or at least 65%, or at least 70%, or at least 80% and / or up to about 99% (w / w) of the composition, or up to about 97%, or up to about 95%. For example, the dermatologically acceptable carrier (ii) may constitute from about 60% to about 97% (w / w) of the composition, more usually from about 65% to about 97% (w / w), and more typically from about 70% to about 95% (w / w) of the composition. P41814W0

[0066] 10

[0067] The dermatologically acceptable carrier (ii) typically comprises one or more substances (for example two or more, or three or more) selected from water, propylene glycol, butylene glycol, glycerol and mixtures thereof. Suitably, the dermatologically acceptable carrier (ii) comprises (or consists of) water, propylene glycol and butylene glycol.

[0068] In some embodiments, water constitutes the major component of the dermatologically acceptable carrier. For example, water may constitute at least 60% (w / w) of the dermatologically acceptable carrier, typically at least 70%, more typically at least 80% and usually at least 85% (w / w) of the dermatologically acceptable carrier. Typically, water may constitute up to 99% (w / w) of the dermatologically acceptable carrier, or up to 97%, or up to 95%.

[0069] As discussed above, the dermatologically acceptable carrier (ii) may further comprise propylene glycol and / or butylene glycol. Propylene glycol may constitute from 1% to 10% (w / w) of the dermatologically acceptable carrier, typically 1% or greater, or 2% or greater and / or typically 10% or less, or 8% or less. Additionally or alternatively, butylene glycol may constitute from 0.5% to 10% (w / w) of the dermatologically acceptable carrier, typically 0.5% or greater, or 1% or greater, or 2% or greater and / or typically 10% or less, or 8% or less, or 7% or less.

[0070] The compositions of the invention typically contain, in addition to components (i) and (ii) above, one or more preservatives (iii).

[0071] The preservatives (iii) can be selected from, for example, phenoxyethanol, benzyl alcohol, potassium sorbate, sodium benzoate, dehydroacetic acid and ethylhexylglycerin, or a combination thereof. Typically, two or more, or three or more of the aforesaid preservatives are present. Preferably, the compositions are substantially free of parabens. Preferably, (at least) phenoxethanol is present as a preservative.

[0072] The total amount of preservative present is typically in an amount from 0.1%, or from 0.5%, or from 1% and / or up to 3%, or up to 2%, or up to 1.5% (w / w).

[0073] The compositions may comprise one or more emulsifiers or surfactants (iv), preferably non-ionic surfactants. Examples of surfactants that may be included in the compositions are glyceryl esters of fatty acids (e.g. glyceryl stearate), polyethylene glycol derivatives of hydrogenated plant oils such as hydrogenated P41814W0

[0074] 11

[0075] castor oil (e.g. PEG 40 hydrogenated castor oil), fatty alcohols such as cetearyl alcohol (a mixture of fatty alcohols, consisting predominantly of cetyl and stearyl alcohol) and polyoxyethylene ethers of fatty alcohols such as ceteareth non-ionic surfactants (mainly ethers of cetyl alcohol and stearyl alcohol), for example ceteareth-20. Other examples of surfactants include glucosides, for example decyl glucoside. The total amount of surfactants can be, for example, up to about 5%, or up to 4%, or up to 3% and / or at least 0.1%, or at least 0.5%, or at least 1% (w / w). For example, the total amount of surfactants may be from about 0.1% to about 4% (w / w).

[0076] The cosmetic composition may further comprise a thickening agent or gel. The thickening agent is suitably derived from cellulose. Preferably, the thickening agent is hydroxyethylcellulose. The thickening agent (e.g. hydroxyethylcellulose) may be present in an amount of at least 0.5%, at least 1%, at least 2% or at least 3% (w / w) of the composition and / or in an amount of up to 8%, up to 6%, up to 5% or up to 4% (w / w) of the composition.

[0077] The cosmetic composition may further comprise one or more solvents. The solvent is typically miscible with water. Suitably, the one or more solvents are aprotic and / or have high polarity and thus may be polar aprotic solvents. For example, the cosmetic composition may comprise dimethyl isosorbide (DMI).

[0078] The cosmetic compositions can contain one or more further substances (v) selected from:

[0079] (v-1) PEG-40 hydrogenated caster oil;

[0080] (v-2) glycerin;

[0089] 12

[0090] (v-11) amino acids such as aspartate (e.g. magnesium aspartate) and glycine, alanine;

[0091] (v-12) creatine;

[0092] (v-13) Aloe Barbadensis (optionally in the form of powder);

[0093] (v-14) EDTA salts such as tetrasodium EDTA;

[0094] (v-15) Cocos Nucifera fruit extract;

[0095] (v-16) saccharide hydrolysate;

[0096] (v-17) pearlescent materials such as mica;

[0097] (v-18) skin conditioning agents or emollients such as isostearyl stearate; (v-19) pigments such as titanium dioxide (Cl 77891), yellow ferric oxide (Cl 77492), red ferric oxide (Cl 77491) and black ferric oxide (Cl 77499);

[0098] (v-20) colourings such as Cl 19140, Cl 14700, Cl 42090 and Cl 17200; and

[0099] (v-21) polyvinylpyrrolidine.

[0100] Suitably, the compositions contain one or more (for example two or more, or three or more, or four or more, or five or more, or all of) further substances (v) selected from:

[0101] (v-1) PEG-40 hydrogenated caster oil;

[0102] (v-2) glycerin;

[0103] (v-3) schinziophyton rautanenii kernel oil (manketti oil);

[0105] (v-6) tocopheryl acetate (vitamin E);

[0106] (v-10) citric acid;

[0107] (v-13) Aloe Barbadensis (optionally in the form of powder);

[0108] (v-14) EDTA salts such as tetrasodium EDTA; and

[0109] (v-20) colourings such as Cl 19140, Cl 14700, Cl 42090 and Cl 17200. Suitably, the cosmetic composition comprises: P41814W0

[0110] 13

[0111] (i-a) dihydroxyacetone in an amount of from 5% to 15% (w / w) of the composition;

[0112] (i-b) erythrulose in an amount of from 1 % to 5% (w / w) of the composition; and (ii) a dermatologically acceptable carrier (optionally comprising water, propylene glycol and butylene glycol).

[0113] Alternatively, the cosmetic composition comprises:

[0114] (i-a) dihydroxyacetone in an amount of from 5% to 15% (w / w) of the composition;

[0115] (i-b) erythrulose in an amount of from 1 % to 5% (w / w) of the composition;

[0116] (ii-a) water in an amount of 70% to 85% (w / w) of the composition;

[0117] (ii-b) propylene glycol in an amount of 2% to 6% (w / w) of the composition; and

[0118] (ii-c) butylene glycol in an amount of 1% to 5% (w / w) of the composition.

[0119] Cosmetic compositions, such as tanning compositions, as described herein allow the user to apply and re-apply the composition (e.g. the tanning composition) until the desired makeup look is achieved. Applying more layers of the composition (e.g. the tanning composition) leads to a more prominent change in colour or pigmentation (e.g. a darker colour or deeper tan), while fewer layers give a less prominent change in colour or pigmentation (e.g. a lighter colour or less deep tan). For example, where the cosmetic composition is a tanning composition, application of the tanning composition daily (or more often) will lead to a darker colour over time, whilst less frequent application (for example every few days or weekly) will allow the wearer to maintain a lighter colour.

[0120] In a further aspect, the invention provides a method of applying a cosmetic composition. The method comprises:

[0121] (i) decreasing the volume of the reservoir by an amount to dispense an effective amount of the cosmetic composition through the first end of the hollow cavity into the applicator head,

[0122] (ii) applying the cosmetic composition using the applicator head, and

[0123] (iii) blending the cosmetic composition using the brush. P41814W0

[0124] 14

[0125] The volume of the reservoir may be decreased by twisting a twist dial, which is suitably positioned between the second end of the hollow cavity and the brush.

[0126] The methods of the invention are primarily intended as cosmetic treatments.

[0127] Where the cosmetic composition is a tanning composition, the methods may be referred to as tanning methods or methods of tanning the skin or face or body.

[0128] An advantage of the present invention is that it provides both the cosmetic composition and two types of applicators, all in a single product. This allows easy application of the cosmetic composition onto the user’s skin, face or body (e.g. using the sponge) without spillages or the risk of depositing too much of the composition and subsequent blending of the cosmetic composition (e.g. using the brush).

[0129] Since the applicator of the present invention combines the cosmetic composition, sponge and brush in a single all-in-one product, it is easily portable and useful, for example, when the user is travelling.

[0130] Since the applicator head and the brush of the applicator are both removably connected to the body of the applicator, the applicator head and the brush may be removed from the body in order to be properly cleaned and / or to allow the user to refill or replace the cosmetic composition, for example when the cosmetic composition is running low or has run out entirely. Thus, another advantage of the present invention is that it is cost efficient, since the user does not need to replace the applicator every time the cosmetic composition runs out. Instead, they can just buy refills or replace the cosmetic composition with a new composition. A further advantage of the present invention is that it is environmentally friendly, since the applicator is reuseable and does not need to be discarded I disposed of every time the cosmetic composition runs out (thus, preventing unnecessary plastic waste).

[0131] One way of re-using the applicator after the cosmetic composition has run out is by removing the applicator head and refilling the existing reservoir by pouring or depositing the cosmetic composition through the open first end of the body (i.e. not replacing the body portion or the applicator).

[0132] Another way of re-using the applicator after the cosmetic composition has run out is by removing both the applicator head and the brush and replacing the empty P41814W0

[0133] 15

[0134] body portion of the applicator with a new, replacement body portion containing the cosmetic composition.

[0135] Thus, in another aspect, the invention also provides refill cartridges (also referred to a replacement body portions of the applicator or replacement reservoirs) containing the cosmetic composition. The refill cartridges may comprise just the body of the applicator, or the body and the applicator head. Preferably, the refill cartridges comprise a body and an applicator head because the applicator head (or the sponge) typically needs replacing more frequently (e.g. around every 3 months) than the brush because of the build-up of residue or product which remains on the applicator head after the applicator is used (i.e. the cosmetic composition has been deposited into the applicator head) a number of times. This is particularly true when the cosmetic composition is a tanning composition because the tanning composition can oxidise quickly when exposed to air, meaning that when left on the applicator head (or sponge) it can cause discolouration. It is therefore advantageous that the user can replace the applicator head (or sponge) and / or the body portion of the applicator, without the need to replacement the whole applicator.

[0136] The refill cartridges may also comprise an inner cap. When the refill comprises an applicator head, the inner cap may connect to applicator head to protect the applicator head (or sponge). Alternatively, when the refill does not comprise an applicator head, the inner cap may connect to the open end of the body to secure the opening and prevent the cosmetic composition spilling out. The inner cap is typically removed from the refill before use (i.e. before the refill is used as part of the applicator) and thrown away with the previously used, empty body portion.

[0137] Alternatively, the inner cap may be kept and used to preserve a cosmetic composition stored in the reservoir of one body portion while a different cosmetic composition stored in the reservoir of another body portion is in use. For example, the refill cartridge may contain a different cosmetic composition to the one in the original applicator and the user may swap the body portions in and out of the applicator depending on which cosmetic composition they require. For example, the original applicator may contain a tanning composition, while the refill cartridge may contain a blusher, or vice versa. In another example, both the original applicator and the refill cartridge may contain a tanning composition, but the P41814W0

[0138] 16

[0139] tanning compositions may be of different strengths (e.g. one may provide a stronger or more visible tanning effect I a deeper or darker tan than the other).

[0140] When swapping the body portions in and out of the applicator, the user may wish to protect the composition in the body portion which is not being used by keeping the inner cap and inserting this on to the non-used cartridge or body for storage.

[0141] As well as replacing the (empty) body portion or reservoir, the user may also wish to replace the applicator head and / or the brush, depending on the cosmetic composition they are using and how / where they wish to apply it. For example, the user may wish to use a different shaped applicator head (or sponge) and / or a different shaped brush when using a contour composition vs a foundation or blusher, or when applying the composition to their face vs their body, or when trying out different application I blending techniques (e.g. to achieve a different amount of coverage). Thus, the invention also provides replacement applicator heads and / or replacement brushes. Similarly to the refill cartridges, these may come with inner caps so that the sponge I brush can be protected when in storage I not in use.

[0142] As mentioned above, suitably the cosmetic composition is or comprises a semipermanent make up composition, such as a tanning composition. Where present, the tanning composition does not last as long as permanent makeup, therefore the wearer can regularly update their look as they desire, for example as trends change. A further advantage of the tanning composition is that the user can easily apply (and blend) the formulation themselves at home or when they are out and about. Due to the applicator, the tanning composition is significantly easier to apply compared to using a conventional (body) tan on the face applied with a separate brush which is messier and more technically difficult to apply. The tanning formulation in all-in-one applicator also enables easy reapplication “on the go”.

[0143] The invention will now be illustrated, but not limited, by reference to the specific examples / embodiments below.

[0149] Detailed Description of the Invention

[0150] Applicators according to specific embodiments of the invention, as shown in Figures 1 to 3, are described below.

[0151] Figure 1 is a schematic view showing the components of an applicator according to a first embodiment of the invention. Figure 2 is an external side view of an applicator according to a second embodiment of the invention. Figure 3 is a cross-sectional view of the applicator shown in Figure 2. For ease, components of the applicator shown in Figure 1 which correspond to the components shown in Figures 2 and 3 are provided with the same reference numerals.

[0152] The applicator (10) comprises a body (12), a sponge-containing applicator head (14) and a removable brush (16). The applicator (10) is also provided with two lids or caps; one (18) to cover the applicator head and the other (20) to cover the brush when not in use. The lids attach to the body via a “friction-fit” mechanism (i.e. the components are dimensioned such that lids are held in place on the applicator body, without the need for any additional locking mechanism.

[0153] The body is a hollow cylindrical shape having a length of around 7.5cm and a diameter of around 2.5cm. The body has a first end which is open and connects to the applicator head and a second end which is closed and removably connects to the brush. Between the first and second end there is a circular sidewall surrounding a hollow cavity which defines a reservoir for storage of the cosmetic composition.

[0154] The hollow cavity has a movable base (36) which can be moved up (or down) to decrease (or increase) the volume of the cavity. When the volume of the cavity is decreased, the cosmetic composition is dispensed or expelled through opening (38) in the applicator head (14).

[0155] At the second end of the body (12), between the movable base of the hollow cavity (38) and the removable brush (16), there is a twist dial (30). The moveable base P41814W0

[0156] 18

[0157] (38) can be moved up to decrease the volume of the cavity by twisting the twist dial anticlockwise (or down to increase the volume of the cavity by twisting the twist dial clockwise), via the threaded stem (40). The twist dial can be twisted in small increments of around 15 degrees to allow the user to decrease the volume of the cavity by a controlled amount, which in turn dispenses a suitable amount of cosmetic composition into the applicator head. The twist dial makes a clicking sound when twisted past the threshold angle (around 15 degrees), to let the user know that they have twisted the twist dial enough to dispense some of the cosmetic product.

[0158] The first end of the body connects to the applicator head via a click-fit mechanism between a shoulder portion (34) on the first end of the body and a corresponding neck portion (32) on the applicator head. The neck portion (32) slots inside of the shoulder portion (34) and clicks into place. It is not intended that the applicator head (14) is removed from the body (12) by the user in use, as this would risk spillage of the cosmetic composition. The second end of the body (12) removably connects to the brush (16) via corresponding male (26) and female (24) screw threads. The male part on the body screws into the corresponding female part on the brush.

[0159] The applicator head (14) comprises the substantially cylindrical neck portion having a first closed end and a second open end. In the first closed end is a small hole or opening (38) through which cosmetic composition can pass to move from the reservoir (42) in the body into the applicator head. Inserted into the open second end of the applicator head (14) is a spherical / hemi-spherical sponge (28). The sponge is fixed to the second end of the neck portion of the applicator head such that around half the sponge protrudes out of the neck portion in a substantially hemi-spherical shape.

[0160] The sponge is made from a porous foam material, which is soft to touch. The sponge is protected, when not in use, by the lid (18) which is a cone shape having a pointed tip. The lid (18) is inserted over the sponge (28) and neck portion of the applicator head (14) and fits into place via a friction-fit connection with the shoulder portion of the body (12).

[0161] The brush (22) comprises a handle and bristles. The handle comprises two parts. The first part is the female screw thread portion (24), which facilitates the P41814W0

[0162] 19

[0163] removable connection to the second end of the body, via a threaded spigot (26), and the second part is a protruded portion, which houses the bristles. The end of the handle which connects to the bristles (i.e. the protruded portion) has a slightly smaller diameter than the end of the handle which connects to the body (i.e. the female screw thread portion). This is so that the bristles do not extend past the circumference defined by the sidewalls of the body, meaning that the user can take the lid (20) on and off with ease and without disrupting the bristles. The bristles are made from a synthetic material which is soft to touch. They range from between around 0.5cm in length to around 2cm in length and are arranged in a configuration such that the length gradually increases from one side of the brush to the other. Thus, the brush is an angled brush. The brush is protected, when not in use, by the lid (20) which is a cylindrical shape, having a flat closed end which can be placed on a flat surface to stand the applicator in an upright position. The lid is inserted over the bristles and protruded portion of the brush and fits into place via a click-fit connection with a lip or rim between the protruded portion and the female screw thread portion of the handle.

[0164] An example cosmetic composition, which may be used for tanning purposes, which can be used in the applicators of the invention may be prepared by mixing together the following ingredients:

[0172] 21

[0173]

[0174] Once formed, the cosmetic composition can be poured into the reservoir in the hollow cavity of the applicator and subsequently dispensed and applied to the user via the sponge on the applicator head. Once applied, the composition can then be blended using the brush on the other end of the applicator.

[0175] Equivalents

[0176] It will readily be apparent that numerous modifications and alterations may be made to the specific embodiments of the invention described above without departing from the principles underlying the invention. All such modifications and alterations are intended to be embraced by this application.
