Patented Sept. 24, 1935 UNITED STATES PATENT OFFICE 1 Claim.
This invention relates to calli treatment pads and mounting therefo-r, and more particularly to a composite article of manufacture embodying plasters for the treatment of calli and the like 5 which are adapted to be applied in intertted relation to the surface to be treated.
It has heretofore been the practice to sell to the trade calli treatment pads each of which has an enclosed centrally disposed opening in which may be disposed a piece of medicament such, for example, as a salicylic medicament for the treatment of the calli. The salicylic acid was usually sold attached to a base of gauze or crinoline from which it was necessary to cut a small piece of such size as would t in the opening on the underside of the pad.
This practice has not proven satisfactory for the reason that in the first place no protective covering was provided for the salicylic acid and as a result it deteriorated or crystallized out and thus lost its strength before it was put into use, and in the second place it required that the user go to the trouble of cutting out a piece of medicated material of such size as would fit in the corn pad proper as noted hereinabove.
In other words, no carrier was provided for the medicament or salicylic acid which could be removably stuck to a gauze or crinoline base whereby all that was necessary Was for the customer to simply remove the carrier with the medicament thereon from the base and to apply it to the corn under the corn pad or plaster.
It is therefore an object of this invention to provide in a plaster for the treatment of calli or the like a carrier for a medicament such as salicylic acid which not only affords a means for enabling salicylic acid to be removably supported on a base of gauze or crinoline, but in addition thereto provides a protective `covering for the salicylic acid whereby deterioration of the salicylic acid prior to its use will be materially lessened.
Ano-ther object of the invention has to do with the provision of a calli treatment plaster having a filler which provides the plaster with an impervious barrier as far as the passage of matter from the interior to the exterior of the plaster is concerned whereby the plaster will notbecome unsightly or adhere to the hose or garment of the wearer.
In accordance with the general features of this invention, there is provided a composite article of manufacture for the treatment of calli and the like, which includes a gauze or crinoline base having one or more corn pads removably stuck thereon each of which includes a wall of fabric coated (Cl. 12S-153) with adhesive on its underside and having a central opening and an outer covering over said opening and secured to the wall, and one or more medicated tabs removably stuck on the same gauze or crinoline base. The outer covering of the pad 5 and the tab each include a layer of fabric having therein a filler impervious to the passage of the ingredients of the pad and tab therethrough. Furthermore, the single layer tab is of such size that upon its removal from the base it may be disposed 10 in the central opening of the pad when the pad is applied to a surface to be treated; the layer of the tab serving as both a protective covering and carrier for a coating of medicament such as salicylic acid on its under side. 15
Another feature of the invention relates to the application of the ller to the fabric layer of the plaster which filler is preferably a rubber compound vulcanized to the fabric layer to cause it to penetrate through the mesh of the fabric.
Other objects and features of this invention will more fully appear from the following detail description taken in connection with the accompanying drawing which illustrates a single embodiment thereof and in which 25 Figure 1 is a plan View of the composite article of manufacture for the treatment of calli and the like embodying the features of this invention.
Figure 2 is an enlarged cross-sectional View taken on substantially the line II-II of Figure 1 looking in the direction indicated by the arrows.'
Figure 3 is an enlarged sectional View taken on Y substantially the line III-III of Figure 2 looking in the direction indicated by the arrows and illustrating the construction of the salicylic acid tab.
Figure 4 is an enlarged sectional view taken on the line IV-IV of Figure 2 looking in the direction indicated by the arrows and illustrating the impregnation of the outer fabric layer of the corn pad with a filler, which filler is disposed on the underside of the fabric and is coated with an adhesive. Y
Figure 5 is an enlarged view of one of the corn pads of my invention showing it applied to a corn.
Figure 6 is a cross-sectional view taken on the line VI-VI of Figure 5 and clearly illustrating the intertting relationship of the salicylic acid tab and the corn pad or plaster.
The reference character l0 designates generally a gauze or crinoline base which is of the usual Woven mesh construction. Removably stuck to this base lll on one or more corn pads I l and one or more medicated or salicylic acid tabs I2. It is of course to be appreciated that While I have illustrated the crinoline base Ill as having applied thereto twelve pads I I and twelve tabs I2, the invention is 'not to be thus limited since the base may be made to carry any desired number of such tab and pad plasters.
Each of the pads II as best shown in Figure 2 embodies a wall I5 of fabric coated on its under side with adhesive I6. 'Ihis wall I5 is made of a plurality of laminations which may be cemented or vulcanized together as desired. The wall I5 is of an oval shape and defines a central opening Il which is covered by a top layer I8 secured to the top side o-f the wall I5.
The top or outer layer I8 includes a piece of fabric 20 which has its under side provided with a filler 2l for rendering the fabric 20 impervious to the passage of the ingredients of the pad therethrough. The filler 2I comprises a rubber adhesive mass which is vulcanized on the fabric 20 so as to cause the mass toI penetrate the fabric and to be thoroughly secured to the fabric. The outer surface of the fabric 20, however, remains uncoated and hence has the appearance of the natural fabric.
In order to: secure this' outer layer I8 to the wall I 5, the under side of the coated or filled surface of the fabric 2D has a coating of adhesive material 22 as shown in Figure 4.
In the manufacture of the adhesive outer layer I8, I first spread the mixture of waterproo-ng material or ller 2| upon the fabric 20 by any suitable means such as the spreader knife or calender roll.
The filler 2I, which should contain rubber, is neXt vulcanized by any ordinary process of vulcanization so as to cause it to be made an integral part of the fabric 20. Either a heat cure or an air cure may be used.
The .adhesive coating 22 is then spread, While in a suitable solvent, upon the under surface of the' filled fabric layer, after which the solvent is allowed to dry. Heat may or may not be used as desired.
The rubber ller mass comprising the coating 2| may be made up of a suitable rubberized compound containing substances such as oxide of zinc, lithopone or other minerals which serve as fillers in sealing the mesh of the fabric and which would be reinforced by the rubber content of the compound.
It should also be noted that the coating of the outer fabric layer with a filler does not in any way interfere with the iicxibility of the topy cove-ring layer I8 and that layer may be bowed inwardly as shown in Figure 2 or may be fieXed to conform with the contour of the surface to! which the pad is applied as shown in Figures 5 and 6.
Each of the medicated or salicylic acid tabs. I2 embodies a carrier in the form of a circular disc of fabric 25 (Figure 3) which has applied to its under surface a filler 2 I vulcanized to the fabric 25 so as to become an integral part thereof. This filler 2 I may be similar to the filler 2 I. The filled surface of the fabric 25 also has applied to it a coating 25 having an adhesive characteristic so as to be capable of being stuck to the crinoline base I@ or to the surface to be treated and embodying a medicament such as salicylic acid.
Now it will be evident from Figure 3 that the `layer of fabric 25 of the medicated plaster or tab I2 serves both as a protective covering and carrier for the coating of medicament 26 on its under side. This is advantageous as noted hereinabove in that the protective coating materially retards disintegration of the medicament or salicylic. acid coating 26 whereby the strength of that coating will be preserved for the medical treatment of the corn.
Moreover, as` is evident from Figure 6 the barrier afforded by the filler 2I of the tab I2 aids to prevent the salicylic acid from leaving the -tab and penetrating the under surface of the outer pads II from the crinoline base I0 and places it...
over the medicated tab I2 as shown in Figures 5 and 6. Inasmuch as both the pad and the tab areiiexible, it of course follows that they may be readily bent to conform with the outer contour of the part to which they are applied as is also evident from Figures 5 and 6.
I of course desire it understood that while I have described the medicament coating 26 as preferably embodying salicylic acid it is of course to be understood that any other suitable medicament may be used in lieu of the salicylic acid.
Furthermore, it should be noted that while I have illustrated the corn pads II as being of an oval shape and the tabs I2 as being of a circular shape, these plasters may be made of other desirable shapes without deviating from the spirit of this invention.
I claim as my invention:
A composite article for the treatment of calli and the like, including a pair of members of different sizes, each of said members being in the form of a pad and each having a backing element of fabric the undersurface of which is impregnated with a filler impervious to medicaments used in calli treatment, the outer surface of the fabric being uncoated and in its natural state, the smaller of said members having a medicament on the undersurface thereof, the larger of said members having a coating of adhesive on the undersurface of said impervious filler, and a cushioning element on said coating of adhesive and having a recess therein housing the smaller of said members, said cushioning element also having an undercoating of adhesive, whereby the clean outer surface of the backing of the smaller member adheres to the adhesive coating of the backing of the'larger member to hold the composite article in place and the clean outer surface of the backing of the larger member will remain free from the clothing of a user, said members being adapted for merchandizing as separable units because the imp-ervious coating on the smaller member is adapted to protect said member against deterioration of its medicament.
