Definitions

  • ABSTRACT The bristles of a brush applicator for cosmetics are mounted in a centrally located bushing, which is mounted on radial ribs at the outlet from the barrel.
  • the paste to be applied is forced by a lead screw and piston through the ribs into an ample annular space be tween a surrounding ferrule and the outside of the bushing.
  • a shoulder on the ferrule compresses the tips of the bushing ribs against the outlet, and its outlet nozzle closely engages the bristles and directs the paste into their tip end.
  • the lead screw is rotated by a knob secured to its rear end, which is snapped into the back end of the casing, to advance an octagon shaped piston through a correspondingly shaped barrel.
  • An object of this invention is to provide an efficient, free flowing, simple and economical brush applicator for liquids or pastes, particularly cosmetics.
  • the brush for applying paste dispensed from an applicator is centrally attached in front of the barrel outlet and within a ferrule terminating in a nozzle, which closely engages the tip of the brush extending through it.
  • the paste freely flows through the ample annular space between the bushing and ferrule into the tip of the bristles at the nozzle.
  • the brush may be advantageously mounted in a bushing suspended by radial ribs mounted in front of the outlet. The ribs may slant backwardly to facilitate attachment to the rim of the outlet under a shoulder on the ferrule.
  • An ample annular flow area between the bushing and ferrule facilitates the flow through it and the deposit of the paste onto the tip of the brush promotes efficient application.
  • FIG. 1 is an enlarged view in elevation with cap broken away in cross-section of a brush applicator which is one embodiment of this invention

  • FIG. 1 DESCRIPTION OF THE PREFERRED EMBODIMENT
  • a brush applicator 10 for applying a fluid paste or viscous liquid stored in barrel 12 by brush 14 extending longitudinally outwardly through nozzle 16 at the terminal end of ferrule 18 attached to barrel 12 by skirt 20.
  • Cap 22 covers brush 14 when applicator 10 is not being used.
  • Applicator 10 is highly useful for applying cosmetic substances, such as lip coatings, by rotation of knob 24, which forces the paste out onto the tip end of brush 14 as later described in detail.
  • FIG. 2 and related cross sections show the octagonal interior cross section of barrel 12 within which cupshaped piston 26 is traversed by rotation of lead screw 28.
  • Knob 24 is attached to the rear end of lead screw 28 by engagement of ribbed end 30 within square socket 32 in knob 24, as shown in FIG. 2 and 8.
  • Lead screw 28 is rotatably supported by the disposition of bearing disc 34 within cylindrical section 36 of barrel 12. The rest of lead screw 28 is axially supported within longitudinal cavity 38 of barrel 12 by engagement through piston 26.
  • the flanged front end 40 of piston 26 is octagonally shaped and engages the corresponding shaped inner wall of cavity 38. This maintains piston 26 rotatably fixed relative to barrel 12 to make it advance through it in response to rotation of knob 24 and lead screw 28.
  • Knob 24 has its ridged front end 42 snapped into circular groove 44 within the rear end of barrel l2 and its ratchet tooth 46 engaged within circular pawl 48 in the extreme rear end of barrel 12 as shown in FIG. 12.
  • Knob 24 has its smaller end 50 made compressible by slot 52 to facilitate insertion.
  • the parts previously described are conveniently made of plastics with the exception of the brush 14.
  • the external parts and piston 26 are, for example, made of a strong shock resistant plastic, such as polypropylene, and the internal parts are made of a relatively flexible and self-lubricating plastic such as nylon.
  • Other available materials such as metals may be utilized for the previously described parts with suitable revisions attributable to their different characteristics.
  • Bushing 54 and ferrule 18 are conveniently made of an extruded metal, such as aluminum, suitably plated or anodized.
  • the functional front end of applicator 10 includes brush I4 centrally mounted in bushing 54 in front of and within outlet mouth 56 of barrel 12.
  • Bushing 54 is slightly tapered from its mounting to terminal end and is mounted on radial ribs 58 whose tips are secured to mouth 56 by engagement under shoulder 60 of ferrule 18.
  • Skirt 20 of ferrule 18 closely engages grooved outlet end 62 of barrel 12 to seal it and secure bushing 54 in place.
  • Skirt 20 may include circular ridges (not shown) to engage circular grooves 63.
  • Bell 64 of ferrule 18 surrounds bushing 54 and provides an ample annular flow passage 66 between it and bushing 54.
  • Nozzle 16 of ferrule 18 closely engages near the tip of brush 14 to direct paste 68 flowing from barrel 12 onto the tip of brush 14.
  • the deposit of the paste or viscous liquid in the tip of brush 14 highly promotes efficient painting application. This is highly superior to prior internal feeding which distorts and cakes the brush and interferes with accurate sharp-edged brushing, which is highly important in applying a lip coating cosmetic.
  • Ribs 58 are relatively narrow with ample openings 70 between them thus providing a free flow for paste 68 through mouth 56 of barrel 12 onto annular flow passage 66. Ribs 58 may be described as the portions of a flange remaining when outlets 70 are removed. Flats 72 on ferrule 18 shown in FIGS. 2 and 4 facilitate forming the flat brush tip thereby forming cross section of nozzle l6. Nozzle 16A in FIG. 4A has a round cross section.
  • a brush applicator comprising an elongated hollow barrel for storing a flowable substance, said barrel having an open outlet end, pressure-applying means in said barrel for forcing said substance to flow out of said outlet, a brush having a shank between tip and rear ends and a smaller cross-sectional area than said outlet, support means mounting said rear end of said brush centrally in front of said outlet, a ferrule attached to said outlet end of said casing and about said support means and said shank of said brush, said ferrule being spaced from said support means whereby an ample annular flow passage is provided between said ferrule and said support means and part of said shank, said ferrule having a smaller nozzle tip end, said brush tip extending longitudinally through said nozzle tip end of said ferrule, and said nozzle tip end of said ferrule being disposed closely adjacent said shank of said brush whereby said substance flowing in said annular flow passage is directed onto said shank and said tip of said brush for application by said tip.
  • a brush applicator as set forth in claim 1 wherein said pressure-applying means comprises a lead screw and threaded piston assembly, a circular bearing in the end of said barrel remote from said outlet, a bearing disc on said lead screw rotatably engaging said bearing surface, a knob, and projection and socket means securing said knob to said lead screw whereby turning of said knob imparts rotational movement to said lead screw and advancement of said piston.
