Pass, Ser. no. 22544, group no. 336, filing date Mar. 25, 1970, an applicator for spreading shave cream lather was described that provided for an applicator to be attached to an aerosol container.

BACKGROUND OF THE INVENTION.

I Field of the Invention Dispensing, particularly from aerosol containers (class 222, dispensing) and the simultaneous spreading of the dispensed material (class 118, coating apparatus).

2. Description of the Prior Art The prior art includes: shave cream lather dispensing aerosol containers having a valve for regulating the flow of lather through an orifice with means of actuating the valve; an applicator for the spreading of lather on the face or other parts of the body adaptable for attachment to the aerosol container. (For prior applicator art refer to patent filed by the applicant, Roger D. Pass, Ser. no. 22544, group no. 336, filing date Mar. 25, 1970, Applicator For Shaving Lather). This invention is superior to the existing prior art in that it utilizes a combination of expansion chambers and/or-deflection plates which prevent the lather and the like from squirting from the applicator into the eyes or other undesired areas of the user. There are also incorporated into the applicator improved means of operating the aerosol valve.

SUMMARY OF THE INVENTION In a preferred embodiment, an expansion chamber (i.e., a concave depression) is located in the spreading surface of the applicator. The aerosol valve tube or an extension tube of an aerosol valve tube protrudes through the base of and into the expansion chamber,or protrudes into a convex hub located within the expansion chamber. An orifice or orifices located in the end of the tube which protrudes or located in the convex hub deflects the lather coming through the tube into the expansion chamber preventing the lather from squirting into the eyes or other undesired areas of the user. Valve actuating means include a lever rotatably mounted on the aerosol valve tube or the extension tube and extending to and through a slot in the outside side of the applicator. When pressed down, the lever wedges against the inside top of the applicator and the tube causing actuation of the aerosol valve. To lock, the lever is rotatably snapped in a groove located in the side of the applicator or a stationary collar is fitted around the inside flange of the aerosol container, having at one end a raised portion which when the applicator is rotated around the outside flange of the aerosol container wedges under the lever preventing its downward movement. By holding the aerosol container so that the spreading surface rests gently against the face shave cream lather can be ejected and spread directly on the face or other parts of the body by the spreading surface without theuser having to worry about being squirted in the eyes or other undesired areas.

DESCRIPTION OF. THE PREFERRED EMBODIMENTS FIGS. 1, 2 and 3 are of a cream and lather applicator having a passage 3 adaptable for threading the applicator to the stem of an aerosol valve of the kind operated by tilt motion. This applicator could just as well be attached to a tilt type valve stem by a slide fit of the type shown in FIG. 8. The flat circular spreading surface 1 surrounds a lather impeding means, which is a means'of directing the flow of. contents onto the spreading surface while preventing said contents from squirting haphazardly into the eyes or other undesired areas of the user. It is understood that an aerosol valve which the user could easily and exactly control the ejection of contents therefrom would partially or even totally eliminate the need for the impeding means. The lather impeding means incorporated into this applicator include an expansion chamber 2 and a deflection cap attachable to a tilt type valve stem 6. The ports 4 of said deflection cap 5 provide an egress for the contents of the aerosol container. When assembled, the tilt type valve stem 6 screws or slips on saidpassage 3 so that the ports 4 project into the expansion chamber 2. When the base of the applicator is not resting firmly on the top of the aerosol container the aerosol valve can be actuated by sideway finger pressure on the side of the applicator. Lather is then released through the ports 4, into the expansion chamber 2 and onto the spreading surface 1.

tion means and the spreading surface lies not so much in their form, of which they could take many different shapes, but in their ftmction. The spreading surface could just as well be square, oval, concave, convex, bumpy or any other shape, configuration or size within reason. Its usefulness lies mainly in its function of spreading the contents on the face or other parts of the body, rather than in its form. The primary function of the expansion chamber is to provide a reservoir in which shave cream, lather, gels, or dipilatories can expand and/or accumulate. The user could either simultaneously eject and spread said contents on his body; or the user could first eject enough of contents to fill up the reservoir and then spread the contents on his body. A second function of the expansion chamber, but not necessarily contingent on the first, is to provide a housing for the aerosol valve stem and/or deflection means.

' The usefulness of the deflection means lies in its function of deflecting the lather into the expansion chamber and/or the spreading surface.

FIGS. 4 and 5 show an applicator having a e I 10 adaptable for threading the applicator to the stern of w an aerosol valve of the kind operated by tilt motion. A

flat, circular spreading surface 11 surrounds a lather impeding means which includes an expansion chamber 12 surrounding a deflection hub 19 which surrounds.

said passage 10 and protrudes into said expansion chamber 12. The top of the deflection hub 19 could be above, level with or below the spreading surface 11.

FIGS. '4, 6 and 7 illustrate alocking means, FIG. 4 showing it in the. locked'position. The lock slide plate 16 when pushed to the maximum distance allowed by the elongated slot 18 causes at least one-half of the applicator base to lie over the beveled area 16 of the lock FIGS. 8 and 9 are of an applicator with an impeding means including an expansion chamber 22 and a deflection cover 21 adaptable for attachment as a cover over said expansion chamber'22. The surface of said deflection cover 21 is concave, has a multiplicity of openings 24 to provide an egress for the contents,

and acts as a means for spreading said contents on the face or other parts of the body. The passage 23 is adaptable for attaching the applicator to the stem of an aerosol valve of the kind operated by tilt motion.

FIGS. 10, 11 and 12 show an applicator having: a block ridge 3] which hinders the flow'of lather over the edge of the circular spreading surface 31, exterior sidewalls 33 which attach to the top edge of an aerosol container by the flange 33, a deflection extension tube 36 slidably set in a passage 38 centrally located in the expansion chamber 32 having one end attached to an aerosol valve stem 39 and the other end to a pressing plate 35. Pressure applied to said pressing plate 35 activates an aerosol valve which releases lather into said expansion chamber 32 through the ports 34 and onto said spreading surface 31. The locking means consists of two lugs 30, located on said deflection extension tube 36 which canbe aligned by rotation with the two grooves 37 located on the expansion chamber 32 at the periphery of said e 38, to permit downward movement of said deflection extermion tube 36. By rotating said lugs 30 out of alignment with said grooves 37 downward movement of said deflection extensiontube 36 is locked preventing accidental actuation of the aerosol valve.

FIGS. 13 and 15 show an applicator having a convex spreading surface 41 with three independent opening 44 positioned outwardly along the outside periphery of passage 42 so that the portion of the spreading surface 41' between said openings 44 acts as a lather deflecting means. A continuous groove 45 located on the inside circumference of said passage 42 acts to grip a mating projection located on a tilt type valve stem so that the applicator is capable of snapping on and rotating around said tilt type valve stem.

FIGS. 13 and 14 illustrate a locking means, FIG. 14 showing a top view of the base lock plate 46 having three equally spaced gear teeth 47.

' FIGS. 16, 17 and 18 show an applicator having exterior sidewalls 53 terminating in an expanding flange 53' which grips the top edge of an aerosol container tightly at pivot point 57 and then expands gradually around its circumference to provide a slidable action between the applicator and the aerosol container.

. When pressure is applied to' the finger pressing indent 50, which is molded as part of the exterior sidewalls 53 ports 54 located in the deflection hub'55, into the expansion chamber 52 and onto the spreading surface 51.

A locking means consists of a stationary collar 59 having three levels fitted around the inside valve housing flange 65 of an aerosol container. When the applicator is rotated on the aerosol container, a guiding projection 66 on the underside of the expansion chamber 52 abuts against the side of level 67 and rests upon level 68. .In this position downward movement of the applicator is locked preventing accidental actuation of the aerosol valve. When the applicator is rotated in the opposite direction so that the guiding projection 66 is over level 69 the applicator is unlocked.

FIGS. 19 and 20 show an applicator which is designed to actuate an aerosol valve in the same manner as shown in FIG. 16. The oblique oval shaped spreading surface 61 has an expansion chamber 62 in which a deflection cover 63 with openings 64 can be inserted. The deflection cover 63 provides an almost completely smooth flat surface for spreading lather.

FIGS. 21 and 22 show an applicator in which the ports 74 are located in the deflection hub 73 which rises above the flat circular spreading surface 71. For best results, the tubular holes in the deflection hub 73 should be so directed that the lather flows from said ports 74 out and down upon said spreading surface 71. The deflection hub 73 can also act as a spacer between the face and said spreading surface 71.

FIGS. 23, 24, 25 and 26 show an applicator having exterior sidewalls 83 terminating in a flange 87 which grips the top edge of an aerosol container. The deflection extension tube 85 of the lever arm 88 projects through the passage 84' and rotatably engages the stem 86 of the aerosol valve. When downward pressure is applied to the pressing button 88 of the lever arm 88 which extends through the slot 77 in the exterior sidewalls 83, the end of the lever arm 88 opposite the pressing button 88' wedges against the top of the applicator at point 80 and causes downward movement of the aerosol valve. Lather is then ejected through the deflection extension tube 85, out from the ports 84, into the expansion chamber 82 and onto the spreading surface 81. A locking means consists of a stationary collar 78 having three projections fitted around the inside valve housing flange 79 of an aerosol container. When the applicator is rotated around the aerosol container so that said lever arm 88 abuts against the side of projection 76' and rests upon projection 75, the lever arm 88 is locked preventing accidental actuation of the aerosol valve. When the applicator is rotated in the opposite direction so that said lever arm 88 abuts against the side of projection 76, the lever arm 88 is unlocked.

FIGS. 27, 28, 29 and 30 show an applicator having exterior sidewalls 93 terminating in flange 97 which grips the top edge of an aerosol container, and having interior sidewalls 90 which grip the inside valve housing flange 99 of an aerosol container. A lever arm 98 is rotatably mounted on a deflection extension tube 95 which is seated on the aerosol valve stem and extends through the passage 94'. The lever arm 98 projects through three linear slots, slots 100 and 101 located in the interior sidewalls 90, and slot 102 located in the exterior sidewalls 93, and terminates on the outside of the exterior sidewalls 93 in a pressing button 98. The ports 94 of the deflection extension tube 95 project into the expansion chamber 92. All three of the slots are horizontally elongated to allow for horizontal rotation of the lever arm 98. Only slots 101 and 102 need be vertically elongated to allow for downward movement of the lever arm 98. When downward pressure is applied to the pressing button 98', the other end of the lever arm 98 wedges against the top of the slot 100, causing downward movement of the aerosol valve. Lather is then ejected through the deflection extension tube 95, out from the ports 94, into the expansion chamber 92 and onto the spreading surface 91. A locking means consists of the L-shaped slot 102. When the lever arm 98 is rotated so that it rests in the horizontally elongated portion of the slot 102, the lever arm 98 is locked preventing accidental actuation of the aerosol valve.

FIGS. 31 and 32 show an applicator having exterior sidewalls 113 terminating in flange 113 which grips the top edge of an aerosol container. A push arm 118, seated upon the stem 115 of a tilt type aerosol valve, is slidably set transversely in the passage 117, extends outwardly through slot 116 located in said exterior sidewalls 113 and terminates in a lock button 119. When inward pressure is applied to said lock button 119 the push arm 118 causes sideways movement of the aerosol valve. The contents of the aerosol container are then ejected through the port 114 of said push arm 118 into the expansion chamber 112 and onto the spreading surface 111.

FIGS. 33 and 34 show a very simple applicator being in the form of an aerosol valve protective cap with a concave spreading surface 121. To operate, said protective cap is removed from the aerosol container and a portion of the contents is ejected onto the concave spreading surface 121 which acts as a holding reservoir for the contents. The applicator is then held next to the face or other parts of the body and the contents are then spread on same by the user.

It is understood that the lather impeding means could also apply to the impeding of not only shave lather but also shave creams, gels and depilatories. Therefore, the lather impeding means as described in the specification will be referred to as the content impeding means in the claims.

It should be understood that the invention is not to be limited to the particular embodiments disclosed, as

these are intended to be illustrative of the invention. It

also should be noted that some advantages may be gained by using particular embodiments of the disclosed ideas and/or prior art in combinations not shown with each other. Undue multiplicity would result from trying to show every possible combination.
