United States Patent 3,347,410 MIXING ASSEMBLIES FOR APPLICATORS Gilbert Schwartzman, 20 Wilmot Circle, Scarsdale, NY. 10583 Filed Aug. 31, 1966, Ser. No. 576,429 8 Claims. (Cl. 222-80) This invention relates to mixing assemblies for an applicator, and has for its primary object the provision of a single package assembly for facilitating the separate shelf storage of two substances adapted to be thereafter mixed, and further facilitates the application of the mixture through a novel applicator head integrally connected by a bellows to a fitting for attachment to the neck of a container.

The present invention is especially adapted for use with two materials or substances which have an extended shelf life when not mixed, but which must be utilized relatively soon after mixture to prevent deterioration. Various cosmetics, medications, hair dyes, pigments, epoxy adhesives, polishes, cleansing solutions and the like have the foregoing characteristics. For example, conventional hair dyes employ a base material such as a peroxide solution or the like, with which a pigmented material or solution is mixed for immediate application on the hair. The color is determined by the make-up of the pigmented solution. If the pigmented material is mixed with the base and allowed to stand, the mixture may rapidly deteriorate and thus become unusable. It is often very messy to mix these solutions together using separate containers, and the present invention overcomes these difliculties by providing a unitary storage and mixing facility, but also has the additional advantage of providing for convenient application of the mixed fluid by providing for convenient flow of the mixed fluid onto the applicator surface.

One of the important objects of the invention resides in the provision of a stem integrally formed with the applicator head and bellows and so arranged as to open a sealing member to permit mixing of the materials upon depression of the applicator head and bellows.

Futher objects of the invention reside in several different types of novel sealing means adapted to be opened upon initial actuation of a stem to permit mixture of the substances. The sealing means may be in the form of a frangible plate or bottom portion of a retainer ring, a seal bonded or spin welded to the retainer ring, or a plug or container detachably secured to the retainer ring.

Another object of the invention resides in the provision of an applicator that permits the separate shelf storage of two substances of an unstable mixture and which facilitates the mixture of the two substances and further facilitates the application of the mixture immediately after mixing using a novel applicator head, all without removing the substances from the simple assembly comprising the present invention or requiring any exterior handling thereof.

The construction of this invention features an applicator for use with a container provided with a neck having an open, end and having a first substance disposed therein, the applicator comprising a retainer ring having a projecting portion for reception in said neck, and a portion overlying said open end. The applicator further including an outer fitting detachably engaging the outer surface of said neck, an applicator head having openings therethrough, a resilient bellows integral with said applicator head and said fitting and connecting said fitting to said applicator head. The projecting portion is provided at the lowermost end thereof with sealing means to hold a second substance within said retainer ring. A stem is integrally formed with and depends from said applicator head and is engageable with said sealing means upon depression of said applicator head and bellows to open said sealing means to permit the second substance to mix with the first substance.

Still further objects and features of this invention reside in the provision of an applicator which is simple and inexpensive to manufacture, easy to use, capable of metering fluid, such as hair coloring dyes and the like, of various viscosities in an eifective manner, and which is especially adapted for use in connection with cosmetics, medications, hair dyes and tints, polishes, and the like.

These, together with the various ancillary objects and features of the invention, which will become apparent as the following description proceeds, are attained by this applicator, preferred embodiments of which have been illustrated in the accompanying drawings, by way of example only, wherein:
