Application March 15, 1951, Serial No. 215,788
My improvement pertains to a perspiration shield, better known as an underarm perspiration shield, a device designed for the protection of womens dresses against damage by perspiration. The device itself is Well known in trade, but in the form in which it is known it has to be aiXed to the respective portion of a dress where the shield may be retained at least in a semipermanent manner. However, there are dresses in which the sleeves are cut in such a manner and are so wide at their upper portion that they do not come near enough to the underarm portion of the body, so that a shield attached to a dress would afford no protection at all. The object, therefore, oi my improvement is to provide a shield which instead of being applied to a dress is applied directly over the portion of the body, speciiically to the skin under the arm of a person using the shield. To eect this Durpose I have designed a shield which is provided with adhesive means along its periphery. A further object of my improvement is to provide a shield which even though adhering to the body, as above stated, will leave Ventilating spaces about its periphery.
A further object of my improvement is to provide a shield simple in its structural design and so economical in cost that it may be discharged after its use, with a new shield being always available for each occasion when the use of a shield is desirable.
I shall now describe my improvement with reference to the accompanying drawing in which:
Fig. l is a plan elevational view of my shield;
Fig. 2 is a plan elevational view of a modified species of said shield;
Fig. 3 is a sectional view on line 3--3 of Fig. 1;
Fig. 4 is a perspective View, in reduced size, of the shield shown in Fig. 1 in its partly folded condition;
Fig. 5 illustrates a shield in its normal position under the arm of a person;
Fig. 5 is a plan elevational View of another species of my shield;
Fig. '7 is a sectional view on line 'I-l of Fig. 6.
Similar numerals refer to similar parts throughout the several views.
The shield shown in Fig. 1 consists of a circular pad iii preferably made of a single layer of textile material, such as cotton cloth, woven loosely in order that it may easily absorb moisture. li desired, said pad itl may be treated with a suitable medicament to reduce perspiration or to neutralize its odor. The pad is mounted centrally on a backing I I which is also circular in shape, being of a diameter exceeding that of the pad by an annular marginal portion I 2. Said marginal portion is provided with two V-shaped cuts i3 disposed in a diametrical relation to each other, as best shown in Fig. 1, the V-cuts marking the end of a diametrical line Ill, along which line the shield may be folded, as shown in Fig. 4. The backing Il is to be made of a moistureproof material, such as rubberized cloth, rubber, or plastic, the object being to prevent the moisture of perspiration from penetrating the fabric of said backing outwardly.
The above-said marginal portion I2 is surfaced with a suitable adhesive substance, the adhesive substance being preferably spread only over segments I5 of the marginal portion, as shown in Fig. l, leaving free spaces I6 therebetween. The said adhesive substance may be used as a means of binding the pad Il! to its backing I I, the location of the substance for that purpose being shown in Fig. 3. As disclosed therein, said adhesive substance may extend inwardly, that is towards the center of the shield extending under the peripheral portion of pad Il), as shown at I'I. This arrangement will eliminate the necessity of spreading the adhesive substance all over the surface of member Il.
The shield shown in Fig. 2 differs from that shown in Fig. 1 in only one respect, namely in that the marginal portion of the backing member II is covered with an adhesive substance all over, as shown at I8.
The species of my shield shown in Figs. 6 and 7 is made only of one layer I9 of a suitable material, such as an absorbent cotton sheet or the like, but is treated on the outer surface 20 to be moisture-proof. The opposite or top surface is provided along its periphery with an adhesive substance 2l, the substance being applied preferably intermittently in a manner similar to that disclosed with reference to Fig. 1.
While the shields shown in the drawing are all disclosed to be circular in shape, it will be understood that this is a matter of choice and that any other shape may be chosen if preferred.
The manner of application of the shield is quite obvious. Assuming that the skin over` which the shield is to be applied is dry, the shield, with the adhesive substance facing the skin, is pressed against said skin until the shield sticks thereto. In this position, as shown in Fig. 5, pad I0 will absorb moisture while spaces I5, free of any adhesive substance, will allow suicient ventilation for release of body heat and body emanations,
' 3 allowing at the same time entry of air into the space between the pad and the skin.
After having described my improvement, what I wish to claim is as follows:
1. A perspiration shield of the kind described, said shield comprising a flat pad of absorbent sheet material, a backing for said pad, the backing being moisture-proof and being of a dia-meter in excess of that of the pad to include a marginal portion allA aroundv the periphery of the. pad, the marginal portion being coated intermittently with an adhesive substance, said pad being bonded to said backing the adhesive substancesand the pad being on the same side of theslfiii-ilrsl.v
2. A perspiration shield of the kind described, the shield comprising a flexible, moisture-proof, sheet member substantially circularin shape.,` an, absorbent cotton pad centrally located upon the moisture-proof member, said pad being of aresser diameter than the moisture-proof member to lea-ve a; maizg-lnalportion. between. itsarim andthe rim! of theizioisture.-prooiv member, seg-ments, ofi
4 the marginal portion being coated on the side supporting the pad with an adhesive substance, the segments being spaced from each other all along the periphery of the pad.
