DISPOSABLE MEDICATED FOOT CAP FOR TREATMENT OF ATHLETES FOOT Filed June 6, 1950 Top insert (impregnated) flnvemom Aflorneys curative powers as also the some Patented Feb. 27, 1951 OFFICE SrQSsBL-E MED IE Q'Q CA AF TREATMENT OF ATHLETES FOOT Delmar Beman, .ln, Bethesda, Application tunes, 195D,Serial n mates 6 Claims. 1

The present invention relates to a disposable medicated foot ca'p primarily for use as a "treatmerit for and preventative of athletes fact.

In previous devices (and means for treating of the disease of the foot commonly known as athletes 'foot various creams, sa-lves and powdered preparations have been utilized with varying degrees of success. These prior known devices, however, have not proven entirely satisfactory for various reasons For example when'salve's and creams have been used, these preparations have a tendency to rub off on the socks of. the user or on bed linen with consequent lesseni g or the footin with the fungi of these articles. -When medicated powder has been used, the powder due to its nature did not adhere suificiently to the users foot in the proper place with a conseqiientiloss of the curative powers. Additionally, it has been found that while some of the medicament previousl used had very good curative properties, nevertheless in those persons susceptible to the disease reinfection "from shoes, socks and bed linen was very prevalent and one of the main'problerns was caused by this reinfection which perpetuated the disease with consequent ill efiects. Another drawback of previous medicaments and devices was that perspiration or running or oozing of the sores tended to carry the medicament from the zone being treated and into the socks and shoes carrying with it fungi which increased the possibility of reinfection due to the fungi becoming lodged therein and an insufiicient amount of fungioide to insurethe killing or inhibiting thereof. 'Also the loss of medicament from the infected area decreases the curvative 'efiects and tends to allow growth and spreading of the fungi.

The device of the present invention has been carefully devised in order to overcome the .previous drawbacks and to insure as far as possible maintaining of the area to be treated sufficiently coated with a medicament to insure curing of the disease and at the same time to "guard against reinfection of the infected area or other portion of the foot. The present device is intended .to bathe or dust the infected area and the surrounding area of the foot with a fungicide powder which kills or inhibits the fungi present in the disease and also to avoid reinfection by bathing or dusting the sock of the user as .well as the shoe or bed linen and the like.

Recognized authorities in fungous disease therapy and primarily fungous infeetions or the feet have long recognized not only the need for effective medicaments and treatments for curing of athletes foot but have also emphasized the iaet'that after the infection is cured strenuous prophylactic measures *n'ius't be taken in order to insur against reinfection especially that of known orsfisceptible individuals. In addition, a need Was felt for a treatment which wo'uld not only cure existing cases but which would effec- {tivli prevent the occurrence of new cases. The pr sent device {fulfills this need in a convenient, inexpensive "and practical wait as will be pointed out more clearly hereinafter.

A further object or the present'invention is to provide a di'spfosable, inexpensively manufactured foot c'a'p containing a inedicaihent impregnated t erein, which will dust the root with a fungicide p wder Eontained in the cap upon action of the foot in a shoe and the like such as when walkin and which is thereafter disposed "0f to aid in preventing reinfection.

A further ob ect "ofthe invention is to render immune thatiare'a of the us'ers foot surrounding the infected area, thus avoiding the spreading of the infection;

Other objectswill be inere eadny apparent from the following detailed discussion of preferred embodiments of the invention taken together with the accompanying drawings in which Figure 1 is a pl'an'vliew or the bOttOm Section Of the foot cap in una'ssembl'ed condition, particularly brokeii away, and having an impregnated insert shown in dotted lines thereon, w

Figure 8 is a perspective View or the foot cap as applied to the foot of auser.

The foot cap generally designated A as shown completed in Figure 5 and as applied to the foot of a user in Figure "8 comprises a bottom portion l0 and atop portion II composed of a plurality or layers Of surgicalauze or similar material which have been so shaped that upon asterribly of the cap, the device will comfortably and relatively snugly fit the foot of the user. The caps can be made in a plurality of different shapes and sizes so as to fit various types and sizes of womens, mens and childrens feet. The actual shaping of the material can be effected by means of patterns [2 and [3 as shown in Figure 6.

In Figure 1 which shows the bottom I!) of the cap, it can be seen that thisportion of the cap is comprised of a plurality of layers of gauze such as I4, l5, and I6 superimposed one on the other. A bottom insert ll as shown in Figure 2 is impregnated with a fungicide powder which will be hereinafter more fully described and which insert H is preferably of slightly smaller dimensions than the bottom 10 and is superimposed on approximately one-half of the bottom l0 when the bottom is in a fiattened'or extended condition as shown in Figure l in dotted lines. Subsequently the two ends of the bottom H are folded over approximately along the center line designated by line BB in Figure 1 so that on either side of the impregnated insert I! a plurality of layers of the gauze will be provided.

When folded over, the completed bottom portion rality of layers of gauze and in like manner with the bottom portion ll] thereis provided a top insert 18 as shown in Figure 4 which is impregnated with a fungicide powder and which is superimposed on the top portion I I which is subse-- quently folded over the insert on line CC in Figure 3 to form the completed top portion of the cap. If desired the bottom insert ll and/or the top insert l8 can be formed to extend substantially over the entire bottom" portion and top on the foot.

portion in flattened or extended condition or as In order to prevent a bunching of the gauze and to insure comfort to the foot of the user the tape l9 can be either formed of separate "ind-ividual pieces or notched around the inside thereof as shown at 20in the drawing; This tape extends around the periphery of the cap with the exception of the straight portion 2lat the rear of the cap which has been formed by the fold along the line BB of Figure l. The rear 22 of v the top portion I l is also formed as a'fold along the line CC of Figure 3. These'folded portions consequently provide an edge which will not ravel and which also will be comfortable to the foot of the user and in conjunction with the bound edge as at IE will form pockets for holding the insertions I! and 18 in place. Due to the porous nature of the gauze forming the layers of the cap the adhesive tape I9 will tend to bind the edges through more than one layer and maintain them in-their relative position.

Preferably attached to the rear 2| of the cap A and on the bottom surface thereof is a strip of adhesive tape 23 which may be perforated as shown at 24 and which when manufactured will have superimposed on the portion having the adhesive material .a protecting. gauze 25* which rounds.

As can be readily seen from Figure 8 of the drawings, the bottom portion of the cap extends backwardly of the ball of the foot and preferably about one-half the length of the foot so as to end in the arch of the foot whereas the top portion extends approximately one-half to twothirds the length of the bottom portion and sufficiently long to extend beyond the joints of the toes so as to cover the probable infected area. The top portion I: can, of course, be modified in shape and length to adapt the same to the use with women's shoes which normally are cut lower than mens and childrens shoes.

In Figure '7 there is shown an alternative method of assembling the top and bottom portions of the cap by means'of an overstitch 26. The overstitch will allow the inwardly turned ends of the gauze layers to lie substantially fiat against the inside of the cap due to the nature of the gauze and thereby will provide comfort for the foot of the user.

Preferably in forming the cap, an additional layer of gauze is provided between the insert I'i' and that portion of the bottom IE! which will be in contact with the sock of the user externally of the cap and also an additional layer of gauze will be provided between the insert it and that portion of the top H in contact with the sock externally of the cap. Alternatively this additional layer of gauze can be made of a finer weave than the remaining layers of gauze so as to be less pervious to the passage therethrough of fungicide powder which will be hereinafter further set forth and for purposes later developed.

The inserts which are formed preferably by a single layer of gauze are heavily impregnated with medicated fungicide powder before they are inserted in the cap in forming the same. The fungicide powder may be impregnated in the inserts in different ways such for example 'where a comparatively water soluble substance is used, it can be placed on the insert in dry form and the insert is subsequently pressed so that the powder will adherev to thegauze insert .in the interstices thereof and be present on both sides ofv the insert. In this instance the powder must be susceptible of adequate cohesion so that in manufacturing the cap and shaping of the same the powder will adhere to the insert and will not tend to dust away but will be of sufficient frangibility so that it will readily disintegrate anddust off. when the user walks or moves a foot so that the powder will sift through the gauze and insufiiate the area whichit sur- In the event that a medicament which is comparatively insoluble in water is utilized it is preferable to form a paste of the powder with water which can be placed on the insert by any well known means such as drawing the insert .through a bath or container 'of theosame after .movements..of;..the.users. foot. z w

3 As an example of medicaments which "can be utilized for impregnating of the inserts there "have been recently devised highly satisfactory preparations and which will be set forth in the following examples showing the preparations and ingredients used.

Each of the foregoing compounds have proven highly satisfactory in the treatment of athletes foot and relatively insoluble in water so that they are well adapted to the wet method of impregnating the insert which is the more desirable method and which compounds have also been found to be readily frangible upon movement of a users foot so that the action of the layers of gauze in movement relative to one another tend to break down the coating over a period of time and the particles of powder then work through the surrounding layers of gauze and insufllate or dust the affected areas of the foot as also the surrounding sock of the user and the shoe of the user.

As set forth hereinbefore either an additional layer of gauze or an additional layer of gauze or closer weave and less pervious is inserted in the cap on that side thereof opposite from the foot of the user with respect to the insert. The reason for this construction is to provide a differential insulfiation or dusting action whereby the greater portion of the powdered medicament is directed to the infected area and the foot of the user with a lesser amount being provided or furnished to the sock or shoe of the user. Due to this differential the infected area receiving the greater amount of the powder is more actively treated with a consequent high curative effect whereas the sock or shoe receives a lesser amount of the powdered medicament but of sufiicient quantity to insure against reinfection due to the fungi getting into the sock or the shoe since the powdered medicament or fungicide as set forth in the preceding examples is adapted to kill or inhibit the fungi in contact therewith. This is a very important feature of the invention so as to prevent recurrence of the disease. The fine powder which comes in contact with the sock will readily filter therethrough so as to contact the interior area of the shoe due to the bellows action that takes place inside the shoe due to the motion of the foot in the interior of the cap in walking. In addition to insuffiating and dusting the infected area with the powder, the area surrounding the infected area in contact with the cap is rendered immune to the infection since this area is likewise dusted with the powder and any fungus which has been transferred to the socks or interior of the shoe through perspiration .or otherwise is also killed or inhibited due to contact thereof by the powder thus avoiding reinfection. If :a person has been exposed to athletes foot and within a reasonable time thereafter wears a pair of the foot caps of the present invention, infection will be prevented-since the dusting action of the fungicide .powderwill kill or inhibit the fungi on contact with the foot and at the same time tend to sterilize th'e'socks and theshoe.

The "foot cap maintains the infected area of the foot from coming in contact with the socks of the user and consequently removes any danger of secondary infection 'due to :dye, lint or dirt inthe sock. it can readily be seen, therefore, from the foregoing description that the device of the pres- =ent invention brings about an ideal condition for treatment of athletes foot as regards treatment of the infected area, prevention of reinfection 'due to fungi in the ."socks or shoes of a user and also acts as .a preventative measure for persons who have been :exposed to athletes foot. Previons known methods and devices did not inany "way providesuch a complete and comprehensive action as does the present device.

The action which takes place when the fungicide powder is dusted on the foot not only tends to kill or inhibit the fungi, on contact, but due to being in powdered form and containing for example talc, boric acid or starch will in conjunction with the porous gauze tend to absorb foot perspiration and thus tend to create a condition on the foot which is not conducive to growth of the fungi.

It may readily be seen from the foregoing description of a preferred embodiment of the invention that a foot cap for use in connection with athletes foot has been advised which fulfills a long felt need not only for curing existing cases of athletes foot, but also .in preventing reinfection or infection of persons never previously infected and the caps are simple to use, convenient, inexpensive and of the highest order of efficiency.

It is obvious that changes may be made in portions of medicaments used and in the shape and construction of the foot caps without departing from the spirit of this invention as defined in the appended claims.
