The present invention is directed to a package for two or more liquid personal care compositions.
Double-ended personal care compositions that include two applicators are generally known in the art. In some instances, the two applicators are used interchangeably with two reservoirs of product, which creates a potential problem of one or both compositions being contaminated. In addition, consumers may be confused about which applicator goes with which reservoir. This is not desirable, especially when the compositions serve non-interchangeable purposes, or are meant to be used sequentially. Even if a dual-ended product comprises only one applicator, the above risks are still present. At least some consumers, when presented with a double-ended package and only one applicator, assume that the applicator should be used for both compositions.
A specific example of this problem exists with the case of a double-ended mascara package. The removal of mascara generally requires the use of a solvent to remoisten and soften the previously applied mascara. The solvent is typically supplied as a liquid to be applied to a cotton swab or tissue. Such a cosmetic liquid may also be referred to as an eye makeup remover or simply as mascara remover. Very recently, mascara packages are available on the market comprising a mascara composition in one end and a mascara remover composition in the other end. Such packages have a composition reservoir and applicator system on both ends. Applicants have found that it is undesirable to mix and match the two compositions; for instance, the remover composition can be transferred to and dilute the mascara composition, the remover composition may degrade the mascara applicator, etc.
Accordingly, it would be desirable to provide a cosmetic package for containing two or more different liquid cosmetic composition and at least one applicator that reduces or eliminates the likelihood of contaminating one of the liquid cosmetic compositions with another.
In order to provide a solution to the problems above, disclosed herein is package for two or more liquid personal care compositions. The package comprises an applicator; a first reservoir; and a second reservoir. The first reservoir holds a quantity of a first liquid composition therein. The first reservoir includes a first reservoir proximal end and an opposing first reservoir distal end. The first reservoir proximal end comprises an open end through which the applicator is inserted and removed, and the first reservoir distal end defines a closed end of the package. The second reservoir holds a quantity of a second liquid composition therein. The second reservoir comprises a second reservoir proximal end and an opposing second reservoir distal end. The second reservoir proximal end comprises a closed end, and the second reservoir distal end comprises an open end through which the second liquid cosmetic composition is dispensed. The applicator is non-removably connected at and extends away from the second reservoir closed end, and the first reservoir is removably attached to at least one of the applicator and the second reservoir and extends away from the second reservoir closed end to protectively encase the applicator.
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:

The first reservoir 122 may include a proximal end 124, a distal end 126, and one or more walls to define an interior volume 150 for holding a quantity of liquid cosmetic composition such as, for example, mascara or mascara remover. The proximal end 124 of the first reservoir 122 is removably attached to and extends axially away from the main body 102 first end 108 to protectively encase the applicator 112. The distal end 126 of the first reservoir 122 may be configured as a closed end 128. An opening 130 may be provided in the proximal end 124 of the first reservoir 122 to permit independent insertion and removal of the applicator 112 therethrough. In certain embodiment, a wiper 132 may be provided (e.g., in and/or around the opening 130) to wipe excess liquid from applicator 112 upon removal of the applicator 112 from first reservoir 122.
The second reservoir 134 may include a proximal end 136, a distal end 138, and one or more walls to define an interior volume 152 for holding a quantity of a liquid cosmetic composition such as, for example, mascara or mascara remover. In certain embodiments, the proximal end 136 may be configured as a closed end 140 of the second reservoir 134. The second reservoir may be non-removably attached and extend axially away from the main body 102 second end 110. In certain embodiments, the second reservoir 134 may be removably connected, for example, to aide in the use of replacement reservoirs. The distal end 138 of the second reservoir 134 includes an open end 142 configured to dispense a quantity of the liquid cosmetic composition disposed therein. The second reservoir 134 may include a cap 144 for covering the open end 142. The cap 144 may be removably attached to distal end 138 by any suitable means known in the art (e.g., twist threads, snap collars, and the like). The cap 144 may be replaced after being removed to provide a liquid impermeable barrier at the open end 142 of the second reservoir 134. A wiper 154 or other flow restricting mechanism may be present in the open end 142.
The second reservoir 134 or portion thereof may be at least partially deformable to facilitate dispensing the cosmetic composition disposed therein (e.g., by permitting a user to squeeze out the contents of the reservoir). It is to be appreciated that the second reservoir or any other package 100 component may be rigid or deformable, and the contents may be shaken or poured out, as desired. In certain embodiments, the second reservoir 134 may include one or more additional dispensing means, such as a twist or push-button mechanism, which at least help to urge the cosmetic composition out of the second reservoir 134. It may be desirable to configure the second reservoir 134 for a particular dosing of its contents. While
The main body may be elongated to reflect the size of the first and second reservoirs. Or, as shown in the package 300 of
The packages herein may contain two or more different liquid compositions. Exemplary compositions include, but are not limited to, cosmetic compositions (e.g., mascara, lip stick, lip gloss, blush, concealer, eyeliner, finishing sealant), hair growth compositions, hair removal compositions (e.g., wax or serum), a hair minimizing composition, semi-permanent ink (e.g., for tattooing, cosmetic, or personal adornment), nail polishes, skin care compositions (e.g., under eye moisturizer, anti-aging serum, sunscreen, protective balm), first aid compositions (e.g., liquid bandage, hydrocortisone, cleansing agent, antibiotic ointment), medicinal compositions (e.g., prescription acne treatment, post-surgery ointment, oral medicine for teething or mouth pain), teeth whitening compositions, hair colorant compositions (e.g., for highlighting, root covering, or novelty), and combinations thereof. Other exemplary compositions include compositions formulated to remove, modify, complement, or supplement one or more compositions in the preceding sentence (e.g., nail polish remover, mascara remover).
In certain embodiments, the package herein may be used to apply a first liquid composition as well as remove the first liquid personal care composition with a second liquid composition. In certain embodiments, the present package may be used to apply a first liquid composition and a second, complementary liquid composition. In certain embodiments, the present package may be used for two chemically incompatible liquid compositions; wherein the package is configured to prevent mixing or contamination of the two compositions.
The following are examples of suitable compositions.
a multichromatic, liquid foundation of the present invention is prepared as follows:
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 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.
a skin-care composition is prepared as follows:
Vitis Vinifera
Phase A materials are blended in a container. Phase B materials are blended in a separate container. Phase B is blended into Phase A. The platelet particulates are added after combining Phase A and Phase B.
a long wear mascara composition is prepared as follows:
Phase A ingredients are melted and mixed together with low shear mixing. Phase B is gradually added to the Phase A and then dispersed with high shear mixing. Phase C is then added and mixed in with high shear mixing. The Phase D is then added and dispersed with high shear mixing. The batch is cooled to ambient conditions and the Phase E is added and mixed in.
a mascara containing large wax particles and fibers is prepared as follows:
Phase A is heated to melt the waxes and allow the pigment to be dispersed with a Cowles Blade mixer. Phase B materials are stirred together at ambient conditions, and Phase C materials are stirred together at ambient conditions and then it is added to Phase B (to gel Phase B), and the mixture is stirred and then heated to about 85 C. The Phase A and Phases B/C are mixed together to create an oil (wax) in water emulsion. The mixture is stirred for 15 minutes and then is cooled gradually till room temperature. During the cool down, Phases D and E are added to the mixture and stirred in below 60 C. Phase F is a 10 Decitex 2 mm Nylon-6 polymerized with Carbon Black (D&C Black No. 2) fiber added and mixed to homogeneity. Phase G is spherical polyethylene wax particles that are prepared separately using typical process known in the art such as spray drying. Phase G is added to and mixed with the mascara once the mascara has cooled down to about 25 C.
