ABSTRACT:
FIELD OF THE INVENTION
The present invention relates to the dispensing of hair coloring chemicals and more particularly to a revolving carousel that houses a series of pigment and developer containers, which allow these chemicals to be dispensed in precisely, metered volumes.
BACKGROUND OF THE INVENTION
The cosmetic dying or coloring of hair requires the application of a colorizing solution, which serves to permanently alter the color of the affected hair. In most instances, this colorizing solution is comprised of a number of individual color pigments which are mixed together to yield a particular color or color shade. Given the particular optical or color qualities of each individual color pigment, the mixing ratios required to derive any particular color or color shade are well known. Therefore, to produce a dye of a specific color simply requires the beautician to consult a document or table, which lists the required pigments and the necessary mixing ratio for the desired dye color. As such, it will be appreciated that the reliable production of a particular dye color requires the relatively precise measurement and mixing of the individual pigment components that comprise the color. However, it is often the case that measurement of the exact quantities of each pigment required for the production of a particular color or color shade is a difficult task for the beautician. In general, the pigments are typically supplied to the user in individual bulk containers (typically squeeze type) from which they are eventually dispensed. Thus, the user is faced with the problem of dispensing the coloring pigments from the bulk containers in which they are stored in an accurate and reliable manner.
Not only is it difficult for beauticians to precisely dispense a certain amount from the respective tubes, but in typical beauty salons where many people have access to the color tubes, one often finds a great deal of disorganization. That is, the color dispensers are often found randomly mixed in one or more containers, some full and some only partially full. A great deal of time is lost by the beauticians in their effort to find and organize tubes of particular color. Needless to say, maintaining an appropriate level of inventory for all of the colors typically used is most difficult under the circumstances. Finally, the above approach does indeed lead to an undue amount of waste as partially filled tubes are often discarded.
Therefore, there is and continues to be a need for a dispensing device which allows beauticians to reliably dispense precisely metered volumes of hair coloring pigments and other chemicals (such as developer) associated with the dying or coloring of hair, such that the color or shade of the resulting pigmented hair coloring solution can be accurately controlled.
SUMMARY OF THE INVENTION
The present invention entails a carousel for holding and dispensing plunger type dispensers that are filled with hair coloring compositions. In particular, the hair-coloring carousel includes a base and a carrier assembly rotatably mounted on the base. The carrier assembly includes a structure for receiving a plurality of dispensers. In a preferred embodiment of the present invention, the carrier assembly includes a pair of spaced apart racks with each rack including a series of openings formed therein and wherein the openings formed in an upper rack are aligned with the openings in the lower rack. A series of plunger type dispensers are secured within the aligned openings of the upper and lower racks. Each dispenser includes a transparent chamber having a plunger reciprocally mounted therein and a lower valve body. The transparent chambers are adapted to receive and hold either a hair coloring composition or a hair coloring developer composition. In a preferred embodiment, the various plunger type dispensers would include an array of different hair coloring compositions as well as a developer composition. By engaging the plunger of the respective dispensers, a beautician can selectively dispenser a predetermined quantity of material from a particular dispenser. By placing a mixing container below the level of the dispensers, the hair coloring compositions and the developer compositions can be dispensed within the mixing container. In fact, the mixing container can be maintained in a generally set or stationary position and the carousel or carrier assembly can be rotated to selectively align certain dispensers over the mixing container.
Consequently, the hair-coloring carousel of the present invention maintains a full set of hair coloring dispensers in an organized state and enables a beautician to selectively dispense a certain quantity of a particular shade of hair coloring composition from a particular dispenser. Thereafter, the carousel can be rotated to where another dispenser is aligned with the mixing container in order that the selective formulation can be dispensed and mixed.
It is therefore an object of the present invention to provide a system for grouping and organizing an array of hair coloring dispensers together such that a wide range of different hair coloring compositions can be disposed at one location in easy reach of the beautician.
Another object of the present invention is to provide a hair coloring station that organizes and holds a series of hair coloring dispensers with certain dispensers holding different hair coloring compositions.
Still a further object of the present invention is to provide a hair coloring station in the form of a carousel that holds a series of hair coloring dispensers on a carousel such that the dispensers can be rotated about a generally vertical axis.
Still a further object of the present invention resides in the provision of a hair-coloring carousel of the character referred to above which employs plunger type dispensers that permit a beautician to dispense a precise quantity of a selected hair coloring composition.
Other objects and advantages of the present invention will become apparent and obvious from a study of the following description and the accompanying drawings, which are merely illustrative of such invention.
