WILLIAM I.. scrummm, or o IIIcAGo, ILLINOIS VPLASTER AND PACKAGE THEREFOR Application led October 3, 1928. `Serial Ilo. 810,163. y

My invention relates to adhesive plasters for use in the removal and .preventlon of bunions, callouses, and similar foot and L skin disorders, and has among its objects the provision of an improved. form of plaster and an improved package mounting therefor.

A further object is to provide an improved plaster which will firmly-adhere to the skin.

A further object is to provide an improved plaster which will not stick to the clothing of the user.

A further object is to provide an improved plaster package in whichthe medicament is protected by the plaster and the plaster may f be removed from the package with or without the medicament as des1red.-

Other objects will appear from the following description, 'referencey being had to the accompanying drawing, in-,which Fig. 1 is a plan view ofthe crinoline sheet upon which the plasters are mounted;

Fig.` 2 is an end elevation thereof;

Fig. Bisa plan view Vof a completely assembled but unfolded mounting sheet and plasters;

Fig. 4 is an enlarged transverse sectional view taken on the line 4-4 of Fig. 3;

Fig. 5 is an enlarged longitudinal sectional view taken on the line 5-5 of Fig. 3;

Fig. 6 is a bottom plan view of a modified form of plaster; and

Fig. 7 is a. sectional view thereof taken on the line 7-7 of Fig. 6. v

In the removal of corns, bunions, callouses, etc., it is desirable iirst to apply a medicament by means of a plaster and after the disorder has vmoval of the hardened skin formation, to apply an unmedicated plaster to protect the part and prevent recurrence of the disorder.

I have provided an improved plaster or ad which may be conveniently used to accomplish both of these objects and purposes.

Referring to Fig. 1, a. sheet 8 of antiseptic crinoline or other suitable material of substantially rectangular shape has a plurality of tabs 10 formedintegrally therewith and extending outwardly therefrom, there being four such tabs 10 equally spaced on each side of the sheet 8 in the particular embod-iment been alleviated by the softening and re-y shown. Each of the tabs 10 comprises a neck portion 12 of decreasing width and a substantially circular head portion 14.

Discs 16Iof medicament are pressed upon each of the head portions 14 of the tabs 10. These discs arelpreferably of wax-like consistency and contain as one of the usual ingredients salicylic acid. .A number of difw erent formulae for the preparation of the medicament are well known in the art and need Anot here be specified. The disc 16 will adhere firmly to the crinoliney head 14 of the tab since it is forced into the interstices present between the threads thereof, and, in fact, is impregnated in the fabric. i

.Each of the tabs 10, after the medicament has been attached, is folded. upon the dotted line 18 so as to lie substantially at upon the sheet 8. Plaster pads 20 arev then placed over the tabs to hold them in place, each of the plasters having a facial depreion or recess 22 suiiiciently large to receive the head 14 and disc of medicament.

As best shown in Figs.,3, 4 and 5, each of the plaster pads comprises a substantially elliptically shaped piece 24`of closely woven fabric having a coating 26 of a suitable anti-V septic adhesive. A pair of elliptical ring shaped fabric pieces 28 and 30 in outline substantially the same as piece 24, are joined to each other by a layer 32 of adhesive and to the piece 24 by its adhesive coating 26. The lowermost ring piece 30 has an antiseptic adhesive coating 34.

From an inspection of Figs. 4 and 5 of the drawing, it will be observed that the peripheral edges of the fabric pieces 24, 28 and 30 are bent downwardly forming curved flanges which cover the edges of the adjacent layers of the adhesive, thus preventing the adhesive from oozing from the edge of theplaster and coming in contact with the hose or other article of clothing of the user. Furthermore,

the plaster, because of this peripheral chamfer, will stick tighter-because parts ofthe clothing or other objects will tend to slide over the plaster rather than abut against and turn up the edge thereof.

Figs. 6 and 7 illustrate aplaster or pad adapted for application to callouses,'bunions,

vals

. 46 having layers 48 and 50 ofadhesive. Its

- edges are chamfered inthe samemanner and it is adapted to be secured upon a sheet of crinoline or similar fabric over a disc of medicament in the same way as previouslyvk described with reference to theplasters 20.

Obviously the pads or -plasters and the discs of medicament may be made of any other shape and size suited to the particular :lliv

use for which they are desired.

- When it is desired to; use the plaster with the medicament, as for initial application to f a. corn, the plaster pad is peeled from the 26 of the adhesive and be retained in the openl ing 22 of the.k plaster.

sheet 8' beginning at the edge opposite the .neck"12, e. g.,point A in Figs. 3 and 4. j As fthe pad is being raised the disc 16 and the head 14 ofthe tab 10 will adhere to the layer After ythe pad has been completely peeled from the main porf 'tion of the sheet-8 it will adhere only to the medicament and the tab, whereupon the plaster with the medicament attached Vmay readetc.`

ily be severed from the sheet by tearing or cutting the neck-12, and applied'to the corn,

After the corn or other disorder has been suiiiciently treated with medicament it is "usually desirable to cover it with a plaster without medicament'to reduce friction upon the part and also to reduce the pressure thereon by distributing the pressure over a greater area. For this purpose I provide a number "of vplasters without medicament, namely,

those in the central longitudinal row (Fig. 3). After this row has been .used 'up the plastersin the two outer rows may be removed from the vsheet withoutthe medicament'by peeling them therefrom beginning with the edges which overlie the necks 12 of the tabs,

e., g., by startingl at the point B,'Figs. 3 and 4.. When theplaster 20 is peeled fromthe sheet 8 in this manner, it will at the same time .-un-

peel fronrthe tab 10 and may thus be rein vsaid vouter plies and adhere to the a septic fabric sheet, a pad comprising a plura ity of plies of close y woven clot joined by intermediate layers of an antiseptic adthereby permanently secured to said sheet,

the greatest cross-sectional area of ysaid disc being) less than the area of said opening, said disc eing adapted to fit within said o ening esive on said exposed portion of the adjacent ply.

2. A plaster pad package comprising an antiseptic sheet, a plurality of plaster pads each having a recessed' adhesive covered face adhering to said sheet, and. a plurality of discs of medicament permanently secured to a portion of ,said sheet adjacent said pads, said discs being smaller'than therecesses in said pads and being adapted to fit therein and be detachably secured to the bottom of the recesses in -saldY pads by adhesion of the portions of the sheet adjacent said discs to the adhesivel on the pad.

3. A plaster pad package comprisingvan.

antise t-ic sheet having a plurality of tongues exten ing outwardly therefrom, pellets of medicament secured to the ends of each of said tongues, said tongues being folded inwardly over said sheet, and a plurality of plaster pads, each' having a recessed adhesive covered face adhering to said sheet, the recesses in said pads lying over the ends of said tongues so that said pellets lie within the recesses and adhere to the plaster pads at the bottoms `of the recesses.

In witness whereof, I hereunto, subscribe my namefthis 1st daly of October, 1928.

and placed in a suitablek sealed pasteboard container.

The -invention is capable .of widevaria-tion within'equivalent'limits and I contemplate such variation as may be desirable or useful in the particular adaptation of the invention shown, or in ,its adaptation forl other purposes. I vdo not restrict myself in any un-l essential particulars, but what I claim and desire to secure by Letters Patent is:
