MASCARA APPLICATOR AND VALVE THEREFOR Filed Nov. 1, 1961 28 4f 2/ K F \l l /6 l-2 INVENTOR. 100/5 6. ZIEGLER HTTOR/VEY 3,084,374 MASCARA APPLICATOR VALVE THEREFOR Louis C. Ziegler, Skyline Drive, Englewood Cliffs, NJ. Filed Nov. 1, 1961, Ser. No. 149,343 9 Claims. {CL 15-521) This invention relates to what are known as mascara applicators employing a brush element movable into and out of the casing of the device in removal of mascara from the casing for brush application to eyelashes. More particularly, the invention deals with a valve device, through which the brush element of the applicator passes in the use of the device, said valve device having means forming vent passages for venting the storage chamber of the casing in the operation of inserting the brush element into the casing so that objectionable leakages of the mascara around the rod of the brush element are obviated.

The novel features of the invention will be best understood from the following description, when taken together with the accompanying drawing, in which certain embodiments of the invention are disclosed and, in which, the separate parts are designated by suitable references characters in each of the views and, in which:

FIG. 1 is an enlarged side view of a mascara applicator, with parts of the construction broken away and in section and diagrammatically illustrating part of the brush portion of the brush element.

FIG. 2 is an enlarged section on the line 22 of FIG. 1, illustrating the interior structure of the valve device.

FIG. 3 is a view similar to FIG. 1 on an enlarged scale showing only part of the construction and illustrating the operation of the valve device in forming the air vent passages around the stem or rod of the brush element; and

FIG. 4 is a section on the line 44 of FIG. 3.

In illustrating one adaptation and use of my invention, I have shown in FIG. 1 of the drawing a mascara applicator, comprising a casing 10, having a closed end, as at 11. Suitably fixed in the open end of the casing is a valve supporting sleeve 12. The sleeve 12 has an outwardly tapered or flared bore 13, the outer end of the sleeve being threaded to receive a removable cap 14 which seats upon an annular shoulder on the sleeve, said shoulder seating on a metallic decorative ring 16 which seats upon the end of the casing 10, as clearly illustrated in FIG. 1. The sleeve 12 has a reduced inner end portion 17, upon which is mounted one of my improved valve devices 18 composed or rubber, synthetic rubber or other suitable flexible material. The device 18 is generally cupshaped in form and the annular wall 19 of the valve fits tightly upon the reduced extension 17. The bottom wall 20 of the valve device has a circumferential aperture 21 therein fitting snugly and tensionally upon the rod or stem 22 of the brush applicator. The inner surface of the wall 20 of the valve device has circumferentially spaced recesses 23, generally of the contour shown clearly in FIGS. 2 and 4 of the drawing. The walls of the recesses 23 taper radially from the wall 19 to the aperture 21, as seen at 24 in FIG. 1 of the drawing and also noted in FIG. 3; thus, the recesses or grooves 23, by virtue of their contour, form four circumferentially spaced substantially half-round gripper pad portions 25, the surfaces 26 of which are in alinement with the Wall of the aperture 21, as clearly seen in FIG. 2 of the drawing. It will, thus, be apparent that the pad portions 25 are of greater thickness at the aperture 21, than the correspondportions of the recessed portions 23.

The rod or stem 22 of the brush applicator or element has an elongated brush portion 27 at the end thereof, part of which is shown at the left of FIG. 1, the brush portion 27 being fixed to a twisted strand 28, as with other devices of this type and kind, the strand 28 being 3,084,374 Patented Apr. 9, 1963 ice materially less in diameter than the diameter of the aperture 21 in the valve device.

In the use of the device, the cap 14 is first removed, which exposes the end of the rod 22 for engagement by the fingers of a hand and the brush element is then withdrawn from the casing 10. In this operation, the wall 20 is pressed firmly in engagement with the end of the reduced portion 17 and forms a positive tensional wiper upon the rod 22 to remove mascara from the rod and, further, in the passage of the brush portion 27 through the valve, a surplus of the mascara is removed from the brush portion 12, leaving a required amount of the mascara thereon for use in treatment of the eyelashes.

Turning now to FIG. 3 of the drawing, in replacing the brush element in the casing, the passage of the brush element, including the brush portion 27 and the rod 22, through the valve device 18 in the direction of the arrow 29, FIG. 3 results in flexing the wall 20 in the manner diagrammatically illustrated in said figure by wiping engagement of 27 and 22 over the gripper pads 25. As a result, the tapered walls forming the recesses 23 are flexed in a manner to form, at the inner ends of the recesses 23, vent apertures 30, allowing air to pass from the bore Ill of the casing 10 outwardly around the rod 22 for escape to atmosphere, as indicated by the arrows 31. In this connection, it will be understood that the fit of 22 in the sleeve 12 is a loose fit. When inward pressure is removed from the brush element, the parts will return to the normal position shown in FIG. 1, effecting and maintaining a seal of the valve around 22 at all times. In the sectional view of FIG. 4, the circumferentially spaced vent passages 30 are diagrammatically illustrated between the pads 25.

With my valve construction, there is no build-up of pressure within the bore 10' of the casing 10 on insertion of the brush element thereinto and, accordingly, the rod or stem 22 is kept free and clear of mascara at all times. Further, it will be apparent that the annular wall 19 of the valve device 18 may be utilized as a means for retaining the sleeve 20 against displacement from the casing 11).

Having fully described my invention, what I claim as new and desired to secure by Letters: Patent is:

1. In a device of the character described employing a casing, a brush element comprising a rod with a brush portion at one end of the rod and movably arranged in one end portion of said casing, a flexible valve supported in the other end portion of the casing, said valve having a flexible wall arranged transversely of the casing, said flexible Wall having an aperture therein of a diameter to snugly engage the rod of said brush element to seal liquid in the first named end portion of the casing, the flexible wall of said valve having a recess on one side surface thereof, leaving gripper pad portions at opposed sides of said recess, and said gripper pad portions extending to said aperture to be engaged by the rod of said element in movement of the element into said casing to flex said wall of the valve in a manner to form a vent aperture in registration with the recess of said flexible wall for escape of air from the casing of the device in said inward movement of the element into said casing.
