ABSTRACT:
FIELD AND BACKGROUND OF THE INVENTION
The present invention relates in general to body sprays and in particular, to a new and useful body spray assembly which comprises a container with a liquid composition having an oil phase in the form of stable droplets which look like pearls or the like.
U.S. Pat. No. 3,920,883, entitled LIQUID COSMETIC COMPOSITION OF A TWO-PHASE TYPE, assigned to Shiseido Co., Ltd., discloses a cosmetic composition containing an oil phase in the form of a dispersion of spheres or droplets, in a homogeneous mixture of organic liquid and water. This patent (the Shisheido patent), which is incorporated here by reference, utilizes finely divided solid particles in the liquid composition to enhance the appearance of the composition in which the oil spheres are transparent, translucent or pearl-like in appearance.
U.S. Pat. No. 4,767,741, entitled TWO-PHASE LIQUID COSMETIC AND METHOD OF PREPARING SAME, which is also incorporated here by reference, discloses a two-phase liquid composition which also contains a dispersion of oil phase spheres or droplets in an organic liquid and water phase to produce a cosmetic having an aesthetically desirable appearance.
This patent also utilizes finely divided solid particles. These particles are the result of precipitated salts in the composition.
A moisturizing composition containing “pearls” of oil droplets is also available from Yves Rosher and is known as BODY THERAPY WITH SAGE & MINT. This product is provided in a glass bottle having a stopper and is shaken before using to disperse the oil droplets into the rest of the liquid composition. The Shiseido patent also advocates the shaking of the cosmetic composition before use for dispersing the oil spheres or droplets into the organic liquid and water phase of the composition.
SUMMARY OF THE INVENTION
An object of the present invention is to provide a body spray which includes fragrance and a moisturizer or other active ingredients, in an attractive assembly comprising a partially or completely transparent container having a spray mechanism for spraying the contents of the container, the contents of the container comprising a composition with a water phase and an oil phase, the oil phase being a dispersion of stable oil droplets or spheres which have a pearl-like appearance and lie in a layer in the composition. Although the preferred embodiment of the invention utilizes oil droplets or spheres which are heavier than the liquid phase and thus form the layer at the bottom of the container, the invention includes compositions which have oil phase droplets that are lighter than the water phase and, thus exists in a layer at the top of the composition.
The composition includes a dispersion of finely divided particles in the form of one or more pigments that the inventors believe contribute to the formation of the stable droplets and which give the droplets a translucent or transparent pearl-like appearance.
Surprisingly, the inventors have found that if certain plastics come into contact with the droplet layer, the droplets are broken, deformed or cling to the plastic parts in sheets or other adverse effects occur. This substantially deteriorates the attractive pearl-like appearance of the droplets and the general appearance of the assembly.
Since an object of the present invention is to provide a composition which can be sprayed, another feature of the invention is to utilize a spray mechanism, which is preferably manual but which may also comprise pressurized aerosol technology, but which has no parts made of the type of plastic which deforms or damages the droplets, near the droplet layer.
Another surprising feature of the invention is that fragrance, which is free of solubilizers must be utilized to form and maintain the pearls, while at the same time avoiding clouding of the aqueous phase. In this way, a substantially crystal clear aqueous phase and a distinct pearl-like droplet layer is produced. Fragrance in the composition will reside in the oil phase due to its lipophilic nature. Solubilizers in the fragrance will impart a hydrophilic nature to fragrance which will adversely effect formation of pearls.
A reservoir pump is used according to the present invention since it does not include a dip tube which extends into the composition. This, both, maintains the stable dispersion of oil phase droplets and produces an attractive container with substantially clear color or colorless liquid above the droplet layer and no unsightly dip tube.
Accordingly, a further object of the invention is to provide a body spray assembly comprising a container which has an upright position and that is at least partly transparent, a liquid composition in the container and spray means connected to the container for spraying the liquid composition from the container. The composition includes an oil phase, an aqueous phase and pigment in the form of particles which are effective to form the oil phase into stable droplets that remain in a droplet layer in the aqueous phase after the composition is allowed to stand for a period of time, the droplets being at least partly visible in the container. The spray means is free of any plastic parts that extend into the droplet layer when the container is in its upright position to avoid rupturing the stable droplets by contact with any plastic parts.
A further object of the present invention is to provide a body spray assembly comprising a container which has an upright position and that is at least partly transparent, a liquid composition in the container and spray means connected to the container for spraying the liquid composition from the container, and the composition including an oil phase, an aqueous phase and pigment in the form of particles which are effective to form the oil phase into stable droplets that remain in a droplet layer in the aqueous phase after the composition is allowed to stand for a period of time, droplets being at least partly visible in the container, the oil phase containing substantially pure fragrance which is free of solubilizer so that the formation of pearls occur in the container and does not cloud the aqueous phase.
The various features of novelty which characterize the invention are pointed out with particularity in the claims annexed to and forming a part of this disclosure.
