Patent Application
20110280647
The present invention is directed to an improved package for applying a liquid personal care product to the skin of a user.
Liquid personal care products are available in a wide variety of packages, including bottles, jars, tubes, and cans. Few liquid personal care products on the market have built-in applicators wherein the product flows through the applicator. Some products on the market, such as certain deodorants, employ a roller-ball applicator technique to deliver product. However, other personal care products such as cosmetics foundations and lotions are traditionally dispensed out of a container into the hand or onto a sponge, and then applied to the skin. This application method however can be unsanitary, wasteful, and messy, and may lead to undesirable post-application hand washing.
Conventional applicators are typically not suitable for desirably applying cosmetic foundations or lotions to the entire face. For example, at least some conventional applicators are ergonomically designed to apply product onto larger areas of the face such as the cheeks and forehead, but not onto smaller skin areas such as the area between the lips and nose. But ergonomic packages may not provide intuitive applicator positioning commonly associated with cylindrical containers and/or applicators. On the other hand, cylinder-shaped applicators may not provide a suitable means to apply product to the smaller areas of the face.
Accordingly, it would be desirable to provide an intuitive package with skin-friendly dispensing that can apply a suitable amount of product directly onto the skin. It would also be desirable to configure such a package to better fit into a user's hand. It would further be desirable to provide an applicator that delivers a suitable amount of product to the skin with each movement of the applicator.
In order to provide a solution to the aforementioned problems, a package for applying a personal care product to the skin of a user is disclosed herein. The package comprises a body for storing and dispensing the personal care product. The body has a first cross-sectional shape and is graspable by the user's hand. The package also comprises an applicator joined to the body. The applicator includes a cylinder-shaped skin-contacting portion. The skin-contacting portion has a second cross-sectional shape and a surface pattern. Each of the first cross-sectional shape and the second cross-sectional shape has a major dimension oriented along a first axis and a minor dimension oriented along a second axis. The major dimensions are greater than the minor dimensions.
While the specification concludes with claims particularly pointing out and distinctly claiming the present invention, it is believed the same will be better understood from the following description taken in conjunction with the accompanying drawings in which:
a is a front elevation view of the embodiment shown in
b is a side elevation view of the embodiment shown in
c is a front elevation view of an embodiment of a package.
a-g are examples of cross-sectional shapes.
a-d are examples of patterns and zones on the skin-contacting portion
a-d are further exemplary embodiments of a package for use herein.
The improved package disclosed herein may be understood more readily by reference to the following detailed description of illustrative and preferred embodiments. It is to be understood that the scope of the claims is not limited to the specific ingredients, methods, conditions, devices, or parameters described herein, and that the terminology used herein is not intended to be limiting of the claimed invention. Also, as used in the specification, including the appended claims, the singular forms “a,” “an,” and “the” include the plural, and reference to a particular numerical value includes at least that particular value, unless the context clearly dictates otherwise.
All percentages and ratios used herein are by weight of the total composition, and all measurements made are at 25° C., unless otherwise designated.
Packages suitable for use herein include a body portion with personal care product disposed therein. In certain embodiments, the personal care product is in the form a liquid or liquid-like substance. Flexible, resilient packages are known in the art and are typically deformable by applying pressure to the body of the package (e.g., by squeezing), which urges a volume of personal care product to an applicator or skin-contacting portion. In certain embodiments, the package may include a one-way valve to enable a user to control the flow of the personal care product. It is to be appreciated that the packages herein may include additional or alternative mechanisms for dispensing the personal care product. Nonlimiting examples of known dispensing mechanisms include electronic pumps; manual pumps; screw-driven pistons or rods; pressurized gasses such aerosols and the like; and trigger pumps.
In certain embodiments, the package may include an applicator for receiving personal care product dispensed from the body of the package and applying it to the skin of a user. All or a portion of the applicator may be fixed or movable (e.g., pivotable, rotatable, detachable, and/or reattachable). The applicator includes a skin-contacting portion for desirably transferring the personal care product to the skin of a user. The skin-contacting portion may be fixed or movable depending on the desired use. The skin-contacting portion is configured to apply the personal care product onto the skin in a desirable manner (e.g., evenly, smoothly, and/or natural looking). In an exemplary embodiment, the skin-contacting portion of the applicator may include a roller, which applies the personal care product while rotating about an axis. In this example, the skin-contacting portion receives the personal care product on its surface (e.g., passively via a discrete reservoir which is positioned in close proximity to the roller such that the personal care composition comes into contact with the surface of the roller as the roller rotates; through apertures in the surface of the roller fed by a channel in liquid communication with the body; and/or by actively urging the personal care composition directly onto the surface of the roller from the body) and, by rotation, deposits the personal care product onto the skin. In another exemplary embodiment, the applicator may include a dosing system wherein the personal care product is dosed through the center of a fixed skin-contacting portion and exits apertures (whether through a porous foam or sponge skin-contacting portion, or via a solid skin-contacting portion with holes fed through an axle).
The skin-contacting portion may includes a surface with a pattern thereon. The pattern may be formed by one or more of the same or different surface features. The surface features may be the same or different size, type (e.g., protrusion versus recess versus aperture), or shape (e.g., elliptical, circular, diamond, square). The surface features may be selected to configured to facilitate the transfer and/or application of the personal care product onto the skin of a user. Particularly suitable examples of surface features for use herein are described in more detail below.
The package may be configured for dual-ended or single-ended dispensing. Dual-ended dispensing applicators may be suitable for circumstances in which a small skin-contacting portion on one end and a larger skin-contacting portion on the other end is desired. Dual-ended dispens, it may be desirable to provide packages that include two or more personal-care products (e.g., a cosmetic primer and a foundation or a skin cleaner and a skin moisturizer) which can be dispensed through dual-ended dispensing applicators. In certain embodiments, the body of the package may include a first end and a second end opposed thereto. The first end may include an applicator and associated skin-contacting portion, while the opposing second end includes a blending tool joined thereto. The blending tool may be used to blend, distribute, or spread the personal care product over the skin.
The package 100 may include an applicator 124 and a blending tool 154. The applicator 124 may be attached to body 102 by any suitable means known in the art (e.g., with screw-threads, a snap-fit collar, or the like). In certain embodiments, the applicator 124 may be integral with body 102 (i.e., the applicator is assembled with the body during manufacturing and is not intended to be removed by a consumer during the product lifetime). In certain embodiments, the applicator 124 may be removably attached to body 102, (i.e., the applicator may or may not be assembled with the body during manufacturing and is intended to be removable by a consumer during the product lifetime without causing damage to the package which would impair its intended function), e.g., for cleaning or replacement with another applicator 124. In certain embodiments, the applicator 124 may be removed to enable user to dispense bulk product directly from body 102. The applicator 124 may be fixed or pivotable, relative to body 102. If in a fixed position, the package 100 desirably includes a suitable opening and closing mechanism (e.g., lever, switch, or valve) to start and stop product dispensing. If the position of the applicator 102 is not fixed, then the position of the applicator 124 may be changed to permit a user to start and stop the dispensing of product. For example, the applicator 102 may be configured to pivot in a plane parallel to the plane of the cross-section 104 such that when the applicator 102 is pivoted a particular amount (e.g., between 1 and 360 degrees or between 1 and 180 degrees), an opening is provided through which the personal care product 180 may be dispensed. When the applicator is pivoted back to the previous position and/or when the applicator is pivoted further (e.g., another 1 to 180 degrees) the opening is closed. Additionally or alternatively, the applicator may be configured to pivot to other positions to change the size and/or shape of the opening, thereby controlling the rate at which the personal care product is dispensed.
The package may include a one-way valve made from rubber or similar material, which is substantially impermeable to the personal care composition 180. The one-way valve may be positioned, for example, between the storage space in the body 102 and the skin contacting portion of the applicator 124. The one-way valve may be configured to be opened by squeezing the body 102 of the package 100, thereby permitting the personal care product 180 to flow through one-way valve, and closed when the squeezing pressure is removed.
As shown in
The package 100 may optionally include a blending tool 154 for manipulating the personal care composition after it has been applied to the skin (e.g., smoothing, spreading, and/or blending the personal care composition with the same or different personal care composition). The blending tool 154 may be attached to body 102 opposite the applicator 124 by any suitable means known in the art, such as with screw-threads, a snap-fit collar, or the like. The blending tool 154 may be removably attached to body 102 so that a user can remove the blending tool 154 to clean it or replace it with a new or different blending tool 154. In certain embodiments, the blending tool 154 may be removed to permit bulk dispensing of the personal care product from the package 100. The blending tool 154 may include a plurality of bristles, a paintbrush, a sponge, a loofah, a shower puff, a massager, or other like utensil suitable for blending, distributing, or spreading a liquid personal care product. For example, the blending tool 154 may be made from flexible and/or soft materials such as rubber, TPE, sponge, combinations thereof and the like. It may be desirable to form the blending tool from a material that is rinsable with a suitable solvent such as water, isopropyl alcohol, or acetone.
a and 3b show the major dimension 106 and minor dimension 108 of the body 102 substantially aligned with the respective major dimension 130 and minor dimension 132 of the skin-contacting portion 126. But in certain embodiments, such as shown in
The skin-contacting portion 126 includes a pattern 144 on its surface. The pattern 144 may be in the form of discontinuous dots, lines, and/or shapes; a continuous matrix; and/or a combination of these. The pattern on the skin-contacting portion 126 produces a corresponding pattern on skin when the personal care product 180 is applied thereto. The pattern 144 may be configured to deliver a discontinuous film of product to the skin, resulting in natural looking coverage. The pattern 144 may be formed by providing apertures that extend through the surface of the skin-contacting portion 126. Alternatively or additionally, the pattern 144 may be formed from recessed and/or raised portions disposed on the surface of the skin-contacting portion 126. In certain embodiments, the personal care product 180 disposed in the package 100 may flow through apertures of the pattern 144 onto the surface of the skin-contacting portion 126 during dispensing and application. In certain embodiments, (e.g., if the pattern 144 includes raised portions on the surface of the skin-contacting portion 126), the raised areas may be configured to pick up the personal care product 180 from, e.g., a trough or tray positioned in close proximity to the surface of the skin-contacting portion. In embodiments where the skin-contacting surface includes recessed portions disposed on its surface, the personal care product 180 may be deposited in the recessed portions and subsequently transferred to the skin of a user.
Exemplary surface patterns 144 for use on the skin-contacting portion 126 are illustrated in
The personal care products suitable for use herein may be provided in a variety of product forms including brushable gels and creams, non-foaming liquids, mechanically pumpable liquids, non-aerosol gels, aerosol gels, aerosol foams, pastes, serums, and sprays.
In a suitable vessel, the water, glycerine, disodium EDTA and benzyl alcohol are added and mixed using conventional technology until a clear water phase is achieved. When the water phase is clear add methylparabens and mix again until clear. Then add the ammonium polyacrylate, titanium dioxide and iron oxides and mix to disperse. Mix the resultant phase with a Silverson SL2T or similar equipment on high speed (8,000 rpm, standard head) to fully deagglomerate the pigments. In a separate vessel, add the KSG21, hydrophobic titanium dioxide and iron oxides, DC245 and the parabens. This mixture is milled using a Silverson on high speed until homogeneous. Next, the colored water phase and the colored, silicone phase are combined and milled using a Silverson on high speed until the water is fully incorporated and an emulsion is formed. Finally, a colored gel is then chosen so as to be significantly different in colour to the blend of titanium dioxide and iron oxides. This is then added and the product is mixed again using a Silverson on high speed. The resulting multichromatic, finished product is then incorporated into the appropriate package.
