T. HUSTON LIQUID DISPENSER Filed Sept. 4', 1940 mm i W Patented Jan. 5, 1943 warren STATES? rarest OFFIQE LIQUH ]::::;NSER I 7 Tom Huston, Miami, Fla.
Application September My invention relates to liquid dispensers. -It. has among its objects to provide an improved dispenser of the type adapted to dispense liquids such as shoe dressings or the like, and, more particularly, an improved dispenser of the type described and claimed in my copending application Serial No. 289,012, filed August 8, 1939, now Patent No. 2,279,320, patented April 14, 1942.
A further object of my invention is to provide such an improved dispenser having improved slit means in the'closure for the resilient container whereby, irrespective of the angular location of the points at which pressure is applied to the resilient container, the liquid therein is caused :to be discharged in an improved manner and in such manner as to facilitate the effective use of the device through eliminating any need for the resilient dispenser to be pressed at specified oppositely located points disposed in a predetermined relation to the slit means. A further object of my invention is to provide an improved closure member for such a dispenser of an improved laminated construction adapted to enable normally closed slit means to continue to function over a long period while the closure retains its resiliency and is free from any deteriorating effects of the liquid, and also adapted to'prevent objectionable seepage while obtaining an improved spreading action. These and other objects and advantages of my improvements will,
however, hereinafter more fully appear.
In the accompanying drawing, I have shown for purposes of illustration certain embodiments which my invention may assume in practice.

Fig. 11 is a plan view of still another modified structure, and
Fig. 12 is a central vertical section of the 010-- sure shown in Figure 11.
Referring first to the illustrative forms shown in Figures 1 to 5, it will be noted that I have therein shown an elongated resilient nitro-cellulose tube or container I having an open end and having a closure member, generally indicated at 2, closing that end; this closure member 2 being of an improved construction hereinafter described.
In this construction, this member 2 is of an improved resilient laminated construction including three flexibly connected layers comprising an upper disc or neck portion 3, an intermediate disc portion 4, andian applying disc-portion 5.
Ofthese, the neck portion 3- is preferably non-communicating cells such, for example, as Neoprene or other suitable synthetic rubber'with the non-connecting cells thereof filled with air or nitrogen. In this construction, it will be observed that, as heretofore, cut cells 6 are provided on the sides of the neck piece and suitably flexibly cemented at'Ba as, for example, by nitrocellulose or neoprene cement, to theinner surface on theopen end of the tube l. Further,
the exposed top surface of the neck 3 carries an impervious skin I, while the bottom surface thereof may be free from skin and comprise cut cells. It will also be noted that an axial cylindrical aperture 8, preferably of substantial diameter, is
provided which extends clear through the disc 3.
Cooperating with this neck piece 3 and suitably flexibly cemented as at 9 to the bottom thereof in such manner as to form a resilient continuation thereof, is the intermediate portion or lamination 4. Herein, it is of slightly larger diameter than the neck 3 and the tube l, and coaxially disposed with respect thereto, and also preferably formed of the same material as the neck 3, and preferably with like skin id on its top surface. This intermediate portion 4, however, has no axialaperture corresponding to the aperture 8, but, instead, is provided with improved normally closed liquid discharge means including a plurality of slits spaced from and surrounding the axis of the member 2 and having their length deplurality of arcuate slits l0, herein, for illustra- 5 tive purposes, three in number, and disposed in a circular arrangement around the axis of the portion 4, with short uncut portions ll of the latter spacing the ends of adjacent slits l0. Further, it will be noted that these slits I!) extend clear through the lamination 4, and that the same are preferably disposed closely adjacent the wall of the axial aperture 8. As shown, this portion 4 is also provided with cut cells on its sides and bottom surface.
Cooperating withthis intermediate portion 1 is also the bottom applying portion 5, preferably forming a beveled extension of the portion 4 and suitably cemented to the cut cell bottom surface: thereof, a by a flexible cemented connection [2, and having the round liquid discharge means comprising the slits It and intermediate uncut portions H also extended from top to bottom through this portion 5 and communicating with the bottom or applying face l3 of the latter.
Herein, this portion 5 i also formed of sponge such slight communication between its cells: that r th applying portion thereof, preferably a thin zone below the doted line [4 shown in Figures l. and 2 is adapted to absorb a small amount of liquid as, for example, a few drops, through the cut applying surface thereof all in such manner as thereby to improve the spreading action while preventing such a depth of penetration as to cause hardening or caking and enabling any retained material to be readily removed under'running water whenever desired.
In the use of my improved construction, with th closure member 2 suitably cemented in the tube I, the latter is grasped near the cap, like a pencil, between the thumb and fingers in any preferred manner. However, instead of requiring that the tube be grasped at diametrically opposite points at opposite ends of the single straight slits heretofore provided in order most effectively to open th latter, in my improved circular slit construction, one or two of the slits It is opened, whatever the angular position of the opposite points of pressure between the thumb and fingers. Thus,any need for care on the part of the user in pressing at any particular marked spots on the container is eliminated, and
even the most careless user, when grasping the container, is enabled readily to obtain the desired limited flow of liquid from the interior of the container through the circular slits. Further, it will be observed that the neck lamination 3 is very freely compressible due to the axial aperture thereon and also permits free communication of the liquid in the container with the inlet of the circular slits at the bottom of the aperture 8. The resilient character of the intermediate sponge rubber portion 4' is also such as normally to maintain the several slits Ill in closed position whenever manual pressure is released. Similarly, the resilient character of the portion 5 also act normally to maintain the slits It] closed,
while the resiliency of the several portions is such that the slits will open whenever the neck piece 3 is pressed, in such manner as to cause'liquid to be discharged through the cut cell applicator surface 13, one or more of the normally invisible slits in this surface, indicated bydotted lines in Figure 5, then being opened- Obviously, as liquid is discharged through the slits, the liquid will be spread by the applicator surface l-3 in a thin film and, as above described, the surface portion l4 permits such a slight absorption of a few drops of liquid adjacent the cut surface H! as to facilitate and expedite spreading.
As a result of my improved construction, it is found that although wherever pressure is applied, one of the circular slits I8 is adapted to be fully opened, or two are adapted to be opened part way, the other slit is so disposed as to tend to be closed by thi pressure in such manner as to prevent any excessive supply of liquid. Further it is found that through my improved laminated portions and their connections to one another, it is made possible to produce a construction which is unaffected by the action of theliquid over long periods, and which further continues to act effectively over long periods to close the slits automatically as soon as manual pressure is released. My improved laminated construction also enables both the slits and the neck piece to be shorter than heretofore, and also enables an axial aperture of substantial diameter to be provided in the neck piece with resultant: increase in the effects of pressure thereon and consequently facilitated opening of the: slits, Attention. is also directed to the fact that, through my improved: laminated structure including the neck piece and intermediate portion, it is. also made possible to utilize an absorbent applicator portion such as described and having the; slits extending therethrough without objectionable results arising from the somewhat absorbent character of the applicator portion. In fact, with my improved connected neck. and intermediate portions, an even greater depth of absorption in the applicator portion than that described is possible without objectionable results, and, although not preferred, with slits. formed. in suitable material and of suitable length, the applying portion, if desired, may be formed of other more absorbent materials than the sponge rubber described, as, for example, a. pile fabric or the like.
In Figure 6, I have shown a modified closure member construction closely similar to that shown in Figures 1 to 5, but wherein the skin and cut cell surfaces are alternatively arranged, the top surface of the portion 4 being free from skin, as indicated at $5, and, instead, skin I6 being provided on the bottom of the neck portion 3. In this construction, it will-also be observed that the bottom applicator portion 5 is thicker relative to the intermediate portion 4, than in the construction shown in Figures 1 to 5. In Figures '7 and 8, a further modified construction is shown, wherein, instead of a sponge rubber intermediate portion, athin resilient. disc I! of ordinary rubber is suitably cemented or otherwise united to the bottom of the neck piece 3 and the top of a thicker applicator portion 5, herein of substantially the thickness of the combined portions 4 and 5 heretofored'escribed; the circular slits la in this construction extending through both the laminations' l1 and 5. I
In Figure 9, instead of one lamination between the neck piece and the applicator portion, two thin laminati-ons I8 and I9 are provided. These laminations are formed of non-absorbent, soft, fine-grained sponge rubber, suchior example, as Rubatex, and comprising tiny cell's-filledwith nitrogen. Also, the applicator portion 20-, which is formed of the slightly absorbent materialsuch as that in the portions 5, is thin and quite'substantially thinner than the total depth of the non-absorbent portions l8 and I9. Thus, the two portions l8 and I8 beingimpervious and-con- 'nected by two cement connections, they willnot of the main portion of the body of the applicator.
This is a structure especially adapted to use with colored, as distinguished fromwhite, dressings, wherein the drying and clogging problemhas heretofore been especially troublesome In Figures 10, 11 and 12, further modified constructions are shown, wherein the circular slits extend through not only the applicator and in termediate portions, but also through the neck [piece 3. In Figure 10,; the neck piece 3 has no central aperture 8 upper portion 4, while the laminations l and 5 therein and is cemented to the are cemented together by a suitable flexible cemented connection I2 and the same circular slits l extend through these portions and also through the neck piece 3 to the inner surface thereof. It will also be understood that if desired an integral single member of the same material as either the portion 4 or 5 may be substituted for the two portions 4 and 5. In Figures ll and 12, it will be noted that instead of discontinuous slits It] in the neck piece 3, one continuous slit 2| is cut out around a central portion or plug 22. The latter herein also has its bottom 23 cemented to the top of the applicator portion 24 around slits it provided therein. Here, also the portion 24, while not limited thereto, is preferably of laminated type, such, for example, as that shown in Figure 9. If desired, the neck piece 3 may also be laminated in any of my forms.
ile in certain figures I have shown the slits "l0 and 2| as openings of substantial width, it will be understood that this is for purposes of illustration, the slits normally being closed and invisible.
While I have herein specifically described certain forms which my invention may assume in practice, it will be understood that the same have been chosen for purposes of illustration, and that *the invention may be modified and embodied in other forms without departing from its spirit or the scope of the appended claims.
What I claim as new and desire to secure by Letters Patent is:
1. In a liquid dispenser, a resilient container having an open end, a resilient closure member f for said end, and normally closed liquid discharge means including a plurality of slits in said member disposed peripherally end to end about a central. portion of said member and openable in response to pressures on the periphery of an adjaecnt portion of said container applied at any opposite points on said periphery.
