Description
Background of the Invention
Garment shields are applied to the portions of garments under the armpits of the wearers to prevent garment soiling from the perspiration of the wearers. They consist of two types, namely, re-usable and disposable shields and in either type generally comprise a pair of multi-layer crescent shaped segments joined together at their concave edges. The re-usable shields are periodically removed from the garments, laundered and re-applied whereas disposable shields are discarded after a single use. Marketing tests have shown that the commercial success of this kind of product depends mainly on its price and that low price can significantly increase sales. As yet, dress shields have not attained the level of popularity as other sanitary products. Although disposable shields can be used in all cases, they are particularly useful in retail garment shops where a low cost convenient means is required to prevent loss profits from garment soiling.
As exemplified by the 1870 dress shield patent of Hotchkiss U.S. Pat. No. 108,908, the use of multi-layer materials for dress shields has been a long standing practice in the prior art. The multi-layer crescent shaped segments have consisted of single or multiple layers of moisture absorbent materials joined to single or multiple layers of moisture repellant materials joined to the moisture repellant layers by stitching, bonding or laminating.
With the foregoing in mind, an effective and convenient disposable garment shield made from a single sheet of material would have an important commercial advantage over the characteristic multi-layer shields of the prior art by substantially reducing the cost of the product in the price sensitive market.
Summary of the Invention
The present invention is related to garment shields and more particularly to a low cost disposable shield for preventing soiling of the portions of garments directly under the armpits of the wearers.
The low cost disposable shield comprises a thin circular coated sheet of a coarse open fiber moisture absorbent paper like material and a means for attaching the coated sheet to the underarm portion of a garment. Extending across the center of the shield is a pre-formed median crease which enables the user to easily fold the shield into two equal halves. The sheet is coated on one side only with a moisture resistent non-hardening adhesive. Applied onto the adhesive coating is a peelable paper which is divided into three contiguous segments bounded by the circular outer margin of the shield and a pair of parallel chordal lines which define the adjoining margins of the segments.
When the shield is placed into service the outer peelable paper segments are first removed to expose the adhesive coating at the end portions of the shield. The shield is then folded about the median crease of the center segment and the exposed portions of adhesive coating at the ends of the shield are pressed against the portion of the garment under an armpit of a wearer.
It is a primary object of the present invention to provide an effective low cost disposable shield for preventing soiling of the underarm portions of garments.
It is another object in addition to the foregoing object to provide a substantial cost reduction in disposable garment shields.
It is another object in addition to the foregoing objects to provide a disposable garment shield which is made from a single piece of coated absorbent sheet material.
Additional objects, features and benefits of the invention will become apparent from the ensuing description and accompanying drawings which disclose the invention in detail. A preferred embodiment is disclosed in accordance with the best mode contemplated in carrying out the invention and the subject matter in which exclusive property rights are claimed is set forth in the numbered claims at the conclusion of the description.

Description of the Preferred Embodiment
Referring now to the drawings wherein like numerals refer to like and corresponding parts throughout the several views, the particular embodiment of a disposable garment shield 10 disclosed in FIGS. 1 through 5, inclusive, comprises a thin circular coated sheet 11 of an absorbent paper like open fiber material and an adhesive means 12 for attaching the coated sheet 11 to the underarm portion of a garment. One side 13 of the coated sheet 11 is moisture absorbing and the other side 14 is moisture repelling. The absorbent paper like sheet material 11 may be optionally impregnated with a deodorizing or pleasant aromatic substance.
The moisture repellant side 14 is completely coated with a thin layer of a preferably insoluble permanently tacky pressure sensitive adhesive 15, such as, a natural or synthetic rubber based cement. The adhesive coating 15 which is applied to the sheet 16 of absorbent open fiber material by rolling, spraying or other suitable means is also the adhesive means 12 for attaching the shield 10 to a garment.
Overlaying and coextensive with the adhesive coating 15 is a peelable paper 17 which is divided into three contiguous segments 18 consisting of a center segment 19 and a pair of identical outer segments 20. The contiguous segments 18 are bounded by the circular outer margin 21 of the shield 10 and in the orientation shown in the drawings are separated by a pair of parallel horizontal chordal margins 22 which define the upper and lower boundaries of the segments 18. An embossed crease 23 preferably extends across the center of the shield 10 and divides the shield 10 into two equal portions. The crease 23 is parallel to the horizontal chordal margins 22 of the peelable paper segments 18. At each end portion of the shield 10 along the crease 23 is a V-notch 24. The purpose of the V-notch 24 is to remove pointed end portions of the shield 10 when it is folded about the median crease 23.
With reference to FIG. 4, as a packaging feature the outer segments 20 of peelable paper 17 may be omitted from one member 25 of a pair 26 of shields 10 when the shields 10 are supplied in pairs 26. In such case, a pair 26 of shields 10 are held together by adhering the exposed end portions 27 of the non-hardening adhesive coating 15 of one shield 25 to the outer segments 20 of peelable paper 17 of the other shield 28. It will be noted that the opposing center segments 19 of peelable paper 17 serve as spacers and enable the user to easily separate the shields 10.
Referring now to FIG. 5, in the preferred manner of using the invention, the outer segments 20 of peelable paper 17 are first removed to expose the outer portions 27 of the underlying adhesive coating 15 at the opposite end portions of the shield 10 for attaching the shield 10 to a garment. Thereafter, the shield 10 is folded about the median crease 23 to orient the moisture absorbing face 13 outwardly and the moisture repellant face 14 inwardly.
The exposed inward facing portions 27 of adhesive coating 15 are then pressed against the underarm portion of the garment to attach the shield 10 to said garment. Thus, when the shield 10 is in position, the outward facing absorbent face 13 will absorb the perspiration from the armpit of a wearer and the inward facing coated moisture repellant face 14 prevents perspiration from contacting the garment.
It will be observed that the retention of the center segment 19 of peelable paper 17 on the shield 10 provides several benefits, namely: (1) the moisture resistance of the inwardly facing surface 14 is increased, (2) the shield 10 is more easily applied to the garment because the center portions of the inward facing surfaces 14 are prevented from adhering to each other, and (3) of shield 10 is more easily removed from the garment.
With reference to FIGS. 6 through 9, inclusive, an alternate embodiment 29 of the present invention is disclosed therein comprising a coated sheet 30 of absorbent open fiber paper like material having a thin coating 31 of a non-adhesive pliable moisture resistent plastic material in lieu of the adhesive coating 15 of the first embodiment 10. The thin plastic coating 31 is applied to one side only of the absorbent paper like material 30 by spraying or other suitable means. Attached to the moisture repellant plastic coating 31, on opposite sides of the median crease 23, is a pair of conventional tape strips 32. Each of the tape strips 32 is double sided coated with a permanently tacky non-hardening pressure sensitive adhesive 33. Applied onto the adhesive coating 33 on the outer side of each tape strip 32 is a peelable segment 34 of a paper like material.
From the foregoing detailed description it will be appreciated that our invention provides an effective garment shield which is easily applied by the user and has the important advantage of a significant cost reduction over the prior art. It will be further appreciated that our invention can be made in large quantities on high speed automatic machinery to reduce manufacturing costs.
Although but two embodiments have been disclosed and described in detail it will be still further appreciated that changes can be made in the shape, details and materials of the invention without departing from the spirit thereof.
