Abstract

A cosmetic applicator includes a tank body containing a cosmetic and a removable cap fitted on a sleeve mounted in the upper end of the tank body. A tube is mounted at its upper end in the sleeve, extends into the cosmetic in the tank body and terminates in a tapered, calibrated mouth. A stem carried by the lower surface of the cap, has an applicator at its free tapered end and a collar fixed thereto just above the applicator. An annular resilient disc provided with openings and of greater diameter than the tube is seated in the sleeve and slidable on the stem. The stem is inserted in the tube until the collar abuts the tapered mouth of the tube and in this position, the applicator is immersed in the cosmetic. When the applicator is withdrawn from the cosmetic for use, it passes through the narrowed mouth of the tube so that excess cosmetic is drained from the applicator into the tube body to provide a measured amount of cosmetic on the applicator.

Claims

1. An improved device for the application of cosmetics of the type comprising, a tank body having an open mouth, a sleeve fitted in said mouth and having a conduit which is coaxial and slightly tapering towards the inside of the tank body until terminating in a cylindrical portion having a flat annular seat, said conduit provided with a central bore followed by a widened portion the broader part of which is oriented towards said tank body a cap having within its opening a coaxial cylindrical body, a stem projecting from the center of said coaxial cylindrical body, an applicator at the end of said stem, a collar affixed to said stem, the outside diameter of said collar registering with the diameter of the bore of said sleeve and being able to pass freely therethrough, said stem being provided with an annular disc of elastomer material which is capable of sliding in tight engagement along said stem and the outside diameter of which is slightly larger than the inner diameter of the coaxially tapered conduit of the sleeve inserted into the mouth of the tank body, wherein said annular disc slidingly mounted on said stem has at least three openings which at spaced points interrupt the cylindrical continuity of the perimeter of said disc, a tube projecting axially from the inner end of said sleeve and which receives said stem and its applicator, the lengths of the tube and stem being dimensioned in such a manner that only said applicator is immersed in the cosmetic contained in said tank body in a location immediately adjacent to a tapered, calibrated diameter mouth provided in the free end of said tube, a collar on said stem, said collar located adjacent to said applicator, said collar having a diameter which is slightly smaller that the inside diameter of said tube in order to define therewith an air-venting passage while the applicator is being inserted.

2. A device, in accordance with claim 1, wherein said tube floatingly engages said sleeve, said sleeve having a recess closed by a nut through which the said tube projects towards the inside of the container, the portion of the tube located in said recess having a ring-shaped flange of larger diameter than the opening of said nut, there being arranged between the said flange and the said nut a small expansion spring capable of biasing said flange against the bottom of the said recess, the said tube extending towards the inside of the sleeve to provide a guide means therefor, that end of the tube which is located inside the tank body being in turn provided with a tapered mouth capable of being closed by said collar on said stem.

3. A device in accordance with claim 1, wherein said tube is anchored in said sleeve and, at its free end located inside the container, is provided with a coaxial widened portion which, in a freely slidable manner, houses a nozzle provided at the lower edge thereof with a flange supporting an expansion spring the opposite end of which, in turn, bears against a lip of said widened portion, said nozzle being slightly conical in shape and being capable of displacement during insertion of the applicator and said nozzle, once the applicator has been introduced, said nozzle remaining in supporting relation against the collar of said stem, thus providing a means of closure and retainment of the cosmetic.

4. An improved device for the application of cosmetics, of the type comprising a tank body having an open mouth, a sleeve fitted in said mouth and having a coaxial conduit tapering slightly towards the inside of the tank body and terminating in a flat annular seat having a central bore followed by a widened portion the broader part of which is oriented towards said tank body, a cap having an opening, a coaxial central body within said opening, a stem projecting from the center of said central body, said stem including a collar adjacent to its end, an applicator mounted on the end of said stem, the outside diameter of said collar registering with the diameter of the bore of said sleeve and being able to pass freely therethrough, an annular disc of elastomer material mounted on said stem, said disc being capable of sliding in tight engagement along said stem and having an outside diameter which is slightly larger than the inner diameter of said tapered conduit of said sleeve, wherein said annular disc slidably mounted on said stem is provided with at least three openings at spaced points which interrupt the cylindrical continuity of the disc perimeter, a tube projecting axially from the inside end of said sleeve inside the tank body, said stem and applicator being freely displaceable within said tube, the lengths of the tube and stem being dimensioned in such a manner that said applicator is immersed in the cosmetic contained inside the tank and body and is located adjacent to the calibrated diameter mouth of said tube, a collar on said stem, adjacent to said applicator, said collar being of a diameter slightly smaller than the diameter of said tube, said collar, during extraction of said applicator, being capable of permitting the passage of air towards the outside, through the tube and openings in said disc, said collar providing a closure means for said tube and means for pushing and removing the disc which controls the passage of air and permits the cleansing of the stem.

5. A device, in accordance with claim 4, wherein said stem is secured in a floating manner to said cap due to biasing by a coaxial spring on an extension thereof housed in a recess provided in a projection of said cap.
