I MEDICAL APPLIANCE Filed March 121 1951 INVENTOR, Irvz'ngFreed. ATTORNE Patented Dec. 23, 1952 UNITED STATES PATENT OFFICE 1 Claim.

This invention relates to medical appliances, and especially to the combination of a specific medical composition and its container, comprising a dual-service lotion in a bottle or the like, which container includes a concavity or trap and is operable to effect selective applications of said composition onto and for treatment of scalps that have diiferent degrees of oiliness; said container being unpartitioned, or having a single cavity, which has a neck or outlet-element, and has an oil-trap or concavity at the base of said neck. The container is preferably transparent, so the condition of the medical composition therein can be seen by the user for determining when it is ready for use on oily scalps, or for use on dry or non-oily scalps.

The dual-service lotion consists of menthol, phenol and resorcinol-mono-acetate, as the prin cipal medicinal ingredients, plus ethyl alcohol and pure water as the medicinal vehicle, plus castor-oil or other oil which is both cohesive and adhesive and is insoluble in water and in a solution of more Water than alcohol and which has a greater specific gravity than that of such solution.

One practical formula of said dual-service tion is as follows:

Per cent Distilled or filtered water, by volume 50 180 proof ethyl alcohol, by volume 45% Menthol, by volume "l Phenol, by volume Resorcinol-mono-acetate, by volume 2 Castor oil, by vo1ume 2 However: other formulas are productive of effective results, for instance where the percentage of alcohol may be as low as 38% or a little lower, and the water about 57% or a little higher, the castor oil remains in a globule at the bottom of the container; but will rise to the surface of the solution if the percentages of alcohol and water are respectively decreased and increased to a few degrees beyond the figures given above. However: The percentage of alcohol may be raised as high as 70%, and the percentage of water as low as without the specific gravity of the vehicle exceeding that of the castor oil and causing it to rise to the top or surface of the vehicle; the sum of said medicinal ingredients being 5%.

It may be seen, therefore, that the gist of this invention is in properly proportioning the water and alcohol for keeping the specific gravity of the solution less than that of the oil therein, so the oil sinks and forms a distinct globule that remains at the lowest part of the bottle or container and does not intermix with the other ingredients except when the solution is agitated, as by the user briskly shaking the container so as to break up the globule into tiny particles that are held in suspension temporarily while a portion of the lotion is being applied on a relatively dry scalp that needs oil along with the other ingredients.

However: when the container is left undisturbed for a while, the tiny particles soon settle to the lowest part of the container and coalesce into a distinct globule, or into separate globules that gravitate to whatever may be the lowest part of the container, whether the container is standing upright or is tilted to a nearly inverted position. When the lotion is poured while the globule or globules remain out of suspension, the oil is trapped in the concavity that adjoins the neck of the bottle or container, while the oilless liquid combination flows thereover and out from the neck and mouth of the container, as when the scalp is oily enough without any added oil.

In the accompanying drawings, the invention is illustrated by Fig. 1 which shows a transparent container tilted about from its normal upright or vertical position, a part being broken away. Fig. 2 shows the same container tilted to about from its normal upright position, a part being broken away.

Referring to these drawings in detail, wherein, similar reference numerals refer to similar parts in both views, details of the invention are described as follows:

The container is here illustrated as a transparent bottle thru which can be seen the globule of oil 3 in the lowest part of the tilted bottle in Fig. 1, and trapped in the concavity 4 in Fig. 2, adjoining the neck 5 through which the oil-free liquid 6 flows, as seen in Fig. 2, when the bottle is tilted, and thru which the oil-permeated liquid flows if the bottle is sufficiently tilted immediately after it has been briskly shaken.

There is nothing novel about the bottle, per se, and its only requirement as to shape is that it must have an internal depression or concavity or oil-trap therein; but it is also important that it be transparent and that the oil-free liquid be transparent, so the user can see and discern when the globule has been sufficiently broken up as to be held in suspension in the combination of other liquids, and to see that the globule is and remains safely trapped when the bottle is tilted in any direction, when it is desired to pour only the oil-free liquid or mixture from the cylindrical bottle whose trap 4 is circumferentially continuous.

This invention is claimed as follows:

In a medical appliance, the combination of a container having a bottom and an outlet and having an oil-trap therein between said bottom and outlet, a normally oil-free mixture of principal ingredients of a dual-service lotion in said container, and a normally distinct globule of coalescent oil in said container and having a greater specific gravity than that of said mixture and being gravity-operable to become detained in said oil-trap while a portion of oil-free mixture is being poured out through said outlet, said globule of oil being adapted to become diffused and suspended in said mixture by agitation of said mixture and oil so that a portion of the said mixture and oil can then be poured out through said out let simultaneously.
