Application August 8, 1939, Serial No. 289,012
12 Claims. (01. 15-133) My invention relates to combined liquid dispensing, and applying devices.
It hasamong its objects to improve such a device, and, more particularly, to provide such an improved device especially adapted for use in dispensing. and applying shoe dressing or the like. A further object of my invention is to provide such an improved construction of the general type described and claimed in mycopending. application Serial No. 110,725, filed November 13, 1936, and one whereinmy prior construction is markedly improved and simplified in various respects enabling improved results to be obtained. A still further object of my invention is to provide an improved combined closure and applying member of an improved construction adapted to be mounted in an improved manner in the open end of an improved resilient fluid containing tube and to provide improved valve means controlling the flow through this member whereby the flow is controlled in an improved manner by compressing and releasing an adjacent portionof the tube. Still other objects of my invention are to provide such an improved construction wherein the improved closure and applying member is maintained ready for use even after being laid away for long periods between. use thereof, and one wherein any tendency of the container to lose resiliency, or of the liquid to deteriorate. or evaporate in the container during long periods. of storage, or between periods of use of the dispenser, is effectually overcome. These. and other objects and advantages of my improved construction will, however, hereinafter more fully appear. a
In. the. accompanying drawing, I have shown for purposes. of illustration one embodiment which my invention may assume in practice.

In this illustrative construction, I have shown a shoe dressing dispensing and applying device especially adapted to dispense and apply socalled liquid shoe white or the like and including an improved dispensing container or tube, generally indicated at l, and having an open end and an improved combined closure and applying member, generally indicated at 2, normally closing said end, all as hereinafter more fully described.
Referring more particularly to the tube I, it will be noted that the same is generally cylindrical and of small diameter and elongated in such manner as to enable it to be held in the fingers substantially after the manner of apencil. For example, as shown inFigure 1, the same may be held between the thumb and middle finger with the tube projecting above the grasping points and the latter so disposed closely adjacent the bottom of the tube as to make the tube readily manipulatable in the fingers after the manner of a pencil, while also being subject to finger pressure thereon, to control the liquid flow as hereinafter described. In a preferred construction, the tube is formed of a usual semirigid yet resilient cellulose nitrate material, such, for example, as Celluloid or other equivalentmaterial, and is closed at its upper end and has its lower end open, and therefore more resilient, and adapted to be closed by the resilient closure and applying member 2 while retaining the resiliency of both and requiring only slight finger pressure. Herein also it will be noted that the interior of this tube I is suitably. coated, as at 3, over its entire liquid containing area in such manner as to prevent what I find to be an objectionable diffusion of moisture through the side walls of such tubes which results in objectionable evaporation of the liquid during storage and, further, in such waterlogging of the material of the tube as to destroy its resiliency. While other wax coatings may be used, I prefer to form this coating of beeswax, pouring this when hot into the tube and relatively quickly emptying the same, as I find that the remaining coating is flexible and satisfactorily imparts Wholly new impervious and resilient characteristics to the cellulose tube. Further, it Will be observed that the inner surface 4 adjacent the open end of the tube is free from the wax coating 3, any such coating of the same I4 on the tube I.
being undesirable to permit the use of my improved cement on this surface 4 to connect thereto a portion of the member 2.
The closure member 2 which cooperateswith my improved container l is also of an improved construction. As illustrated, it includes an inner, herein cylindrical, resilient closure portion 5 and an outer, likewise cylindrical, resilient applying portion 6 of larger diameter cemented to the bottom of the portion 5. In a preferred construction, each of these portions 5 and 6 is of rubber and although both may be formed of the same material as the portion 5, the portion 5 is formed of finer and more expensive sponge rubber known as cellular rubber, while the portion 6 is formed of ordinary high grade sponge rubber. Referring more particularly to the portion 5, it will be understood that the same comprises very small .noncommunicating cells or pores, and that the same are filled with nitrogen instead of air. Further, it will be observed that herein the upper surface .1 of the portion 5 has a skin thereon in such manner as thereby to minimize penetration by 'the liquid, while the side wall 8 thereof is cemented to forma liquid tight yet flexible cemented connection to the surface 4. Herein, the side wall 8 is free from skin, i. e. comprises cut cells, and is cemented to the uncoated portion 4 of the tube I by suitable cellulose nitrate cement,
as indicated at 9. The portion 6 is formed of high grade sponge rubber having somewhat larger non-communicating cells, but these are filled with air. Further, all of the outer surfaces of this portion 6 are free from-skin, i. e. comprise cut cells, while it will also be observed that a slight taper is provided, as at III, on the periphery of the portion 6 in such manner as thereby to increase. somewhat the area of the bottom ap- These outlet means include aslit I2 centrally or axially located in the cellular rubber portion 5 and extending through the latter and a cooperat- I ing communicating slit I3 in the sponge rubber portions leading downward through the latter to the bottom surface II. Both slits are of such character as normally to be closed by the resil-,. iency of the material forming the walls thereof.
Further, each is adapted to be opened when pressure is applied at opposite points on the tube I, indicated by spots I4, and herein disposed slightly above the upper end of the portion 5 and opposite a the opposite extremities of the upper end-of the slit I2. However, while cooperating, each end of the slit I2 acts quite differently from the-other when the member 2 is in operative position in the tube I and the latter is compressed by pressure. applied to the Spots I4.
Considering the operation of the device and referring more particularly to the action of the slit I2, it will be observed that the same is disposed. longitudinally below the desired pressure points,
Thus, when the tube is compressed by a slight squeezing action of the fingers on' these two spots I4, the upper end of slit I2 is mechanically opened, as shown in Figure 8, by the endwise pressure applied to it, at the same time that the walls of the container are deformed by this pressure or flexing. On the other hand, when pressure is thus applied to the spots I4, the slit I3 in the portion 6 is not mechanically opened by the pressure of the fingers, but, instead, is forced open by the liquid which is forced through the this liquid being discharged first through the slit I2 and then through the slit I3, as a result of the same flexing motion which has caused the slit I2 to open. Here, obviously, both slits will close due to the resiliency of the material forming their walls, following relief of finger pressure,
only a minimum of the liquid being then retained therein, and repeated discharges may be effected as and when desired while the expelled liquid is being applied and spread by the surface II.
Thus, the two slits may be considered to function as cooperating valves. Both are normally closed and thus cooperate to prevent seepage. On'the other hand, the slit or valve I2 is mechanically opened at its upper end and by the opposite endwise manual pressure applied tothe extremities of that end, in such manner as to open quite wide and thus provide a free passage for the liquid. However, the slit I3, being more remote, is not thus manually compressed endwise and opened wide, but instead remains closed, o1' substantially closed, until, as a result of the flattening or deformation of the container I, the liquid inthe latter is forced through the then open slit or valve I2, and forces its way between the walls of the slit I3 and out therethrough, spreading over the surface II. When, however,
the finger pressure on the spots I4 is released and as the container springs back to its normally cylindrical shape, both slits or valves I2 and I3 then are closed by the resiliency of the material comprising their walls, 'i. e. are returned to their normally closed position. I
As a result of my improved construction, it is found that due to the'provision of the wax coating 3, the liquid dressing in the tube I can be stored for long periods without the evaporation or deterioration heretofore experienced with such cellulose tubes and heretofore believed to be inherent where such cellulose tubes have been used, with consequent resulting improvement in the resiliency thereof and in the resultant functioning of thedispensing and applying member 2, the slit means in which are normally closed by this resiliency. Further, due to my improved construction and the cementing of the cellular rubber portion 5 to the resilient end of the tube I, it is made possible to obtain a wholly new resiliency in this portion of the dispenser, not only enabling the finger'pressure to be applied closer to the closure member, but also making it possible to obtain my improved valve action including the opening and closing of the slit I2 in the cellular rubber portion 5, while also requiring only a slight squeezing action. Here it will also be evident that a greater pressure, or pressure applied below the spots I4, will act to open the slit throughout its length in such manner as to increase the flow when desired, while like results may also be obtained by varying th thickness of the sections 5 and 6 or the width of the slit. Attention here is also directed to the fact that the use .of cellulose ni trate cement between the uncoated surface 4 of the tube and the cut cells on the side 8 of the portion 5 makes it possible to obtain permanent bonding of the cellulose tube and cellular rubber portion without reducing the resiliency of the parts and while at the same time producing a joint which is water tight, leak proof and non-absorbent to moisture. -Moreover, through the use of such a portion of cellular rubber'and the skin thereon, it is made possible to eliminate seepage through the closure for long periods of time, as, for example, when the dispenser is stored, or between periods of use thereof, while it is found that such cellular rubber does not absorb, swell or deteriorate while in contact with the liquid dressing. Further, by reason of the use of this cellular member of fluid impervious character, it is also made possible for the cells of the under or applicator section to have a limited amount of communication, if desired, for example, sufficient to adapt the latter section to retain a few drops of dispensed liquid for subsequent spreading. These and other advantages of my improvements will, however, be evident to those skilled in the art.
While I have in this application specifically described one embodiment which my invention may assume in practice, it will be understood that the same is shown for purposes of illustration, and that the invention may be modified and embodied in various other forms without departing from its spirit or the scope of the appended claims.
