ARMPIT PERSPIRATION ABSORBING PAD

Abstract

The present invention is a thin transparent pad in various configurations, coated by a durable, water repellent material and a padding of absorbent material on peripheral edges of the pad, which absorb perspiration from under arms of a user and prevent a garment of the user from staining. A plurality of micro channels is disposed on the pad to absorb body moisture and guide it to the padding portion. A plurality of perforations is created on the channels to allow the perspiration discharged in the underarm area to penetrate and become absorbed to the padding portion. The padding portion is made of a slightly thicker material with perforations, which allows the moisture to vapor. The armpit pad contacts the skin of a user or garment by adhesive means.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

[0033] The figures are not intended to be exhaustive or to limit the present invention to the precise form disclosed. It should be understood that the invention can be practiced with modification and alteration, and that the disclosed technology be limited only by the claims and equivalents thereof.

[0034] The invention disclosed herein, in accordance with one or more various embodiments, is described in detail with reference to the following figures. The drawings are provided for purposes of illustration only and merely depict typical or example embodiments of the disclosed invention. These drawings are provided to facilitate the reader's understanding of the disclosed invention and shall not be considered limiting of the breadth, scope, or applicability thereof. It should be noted that for clarity and ease of illustration these drawings are not necessarily made to scale.

[0035] According to FIGS. 1 to 4, the armpit pad 10 of the present invention has a substantially rectangular or oval configuration. The armpit pad 10 comprises a thin transparent fabric 11 coated by a durable, water repellent material 12 to make it water resistant or hydrophobic. This prevents the outer layers of the pad 10, which are in contact with the garment, from becoming saturated with body moisture. The coating of the pad 12 has a thickness of less than 5 microns, and most preferably in the range of 0.001 to 1 microns, and supports water vapor transport through it. The coating 12 may be formed of any suitable hydrophobic material, such as cellulose triacetate, polyamide, polyvinyl chloride, polypropylene, acrylic and polyester fibers.

[0036] A plurality of micro channels 13 is disposed on the transparent pad 11. The micro channels 13 extend longitudinally or radially, depending on the pad shape, to the peripheral edges 15 of the pad 10. The body moisture collected on the surface of the pad 11 is then guided by the micro channels 13 towards the periphery of the pad. These channels 13 preferably permit the moisture produced to direct to the water absorbent portion 15.

[0037] It should also be realized that these micro channels 13 are necessary within the pad 10 to absorb body moisture and guide it to the padding 15 around the exterior portion of the pad 10. The channels 13 allow the perspiration secreted in the underarm area to penetrate and become absorbed to the padding portion 15 and do not remain in the portion of the pad 11 where the most area, which contacts the garment is.

[0038] The padding portion 15 is made of a slightly thicker material with perforations, which allows the moisture to evaporate. The moisture accumulated by the pad may more readily evaporate and ventilate there through. It is to be understood that any desired number of perforations, and channels may be readily accommodated. Thus it may be seen, that the armpit pad 10 of the present invention provides an advanced method, which is adapted to draw and wick moisture away from the skin of a user and to absorb and hold this moisture away from the garment to prevent staining of a garment.

[0039] In another embodiment as shown in FIGS. 1C and 3B the padding area 15 is without perforations. In this case the padding area is made of a highly absorbent material.

[0040] To secure the pad 10 onto the armpit, a pressure-sensitive and skin sensitive adhesive coating 16 is deposited around the outermost surface of the padding area 15. The adhesive coating 16 may be covered with a conventional peel-off strip, which is removed immediately before securing the pad 10 so that it may be secured to the user's underarm with slight pressure.

[0041] When positioning the armpit pad 10 on the underarm, the user peels off the covering strips and positions the pad 10 on the underarm similarly to the position in FIG. 2A, such that the pad 10 covers generally the outer underarm area. The user then presses the adhesive coating 16 against the underarm, to secure to the skin of the user or underarm of the garment.

[0042] The armpit pad of the present invention 10 comes in a variety of sizes and shapes to best fit the user so that it will be comfortable, unnoticeable through sheer clothing, and protectable on loose clothing. Wearing of the armpit pad of the present invention 10, even with a thin-fabric will not affect the shape or the structure of the garment to any noticeable degree yet keeping under arm area dry.

[0043] The method of providing a durable water-repellent coating to a substrate material have been disclosed in prior art and refer to surfaces that are repellent to aqueous liquids (e.g., body liquids) deposited on these surfaces.

[0044] The novel water repellent coating 12 with conjunction of channels 13 on the centre of the pad 10 will absorb body moisture even if attached to the skin or to the garment and keeps underarm portion dry yet prevents of collecting moisture or perspiration in this area and passing onto the garment.

[0045] FIGS. 4A and 4B of the drawings show another embodiment of this invention wherein the padding portion 15 is disposed on sides of the peripheral edges of the pad 10. In this embodiment, the perspiration in the channels 13 will drive to the absorbent padding 15 on the edges. When the arm is bent, the gravity helps to direct the perspiration to the absorbent padding 15. In this embodiment, the adhesive coating 16 will be applied to the padding 15 or alternatively to the backing surface of the pad 10.

[0046] According to the drawings, the armpit pad may be in various configurations. These configurations may be rectangular as shown in FIGS. 1A and 1B or substantially oval as shown in FIGS. 3A and 3B. The actual vertical and horizontal dimensions however, would be preferably in a bigger size (horizontal 7 inches and vertical 4 inches).

[0047] Furthermore, it is to be noted that the hydrophobic coating may be but not necessarily applied to both sides of the transparent pad. For this reason, it is understood that the moisture can be absorbed regardless of the area located on the pad, which is of greater size and area and has more moisture absorbing ability. The thinness of the pad provides for the application of the pad directly to the area of the armpit more readily susceptible to generate moisture while the padding area is employed on the extreme upper and lower of the arm. Therefore, in effect, the pad of the present invention once applied, actually becomes a part of the user.

[0048] The under armpit pad of the present invention 10 is disposable and would come in a variety of skin tone colours and sizes to best fit the user and may be impregnated with an antiperspirant and/or deodorant agents that would enhance the hygienic qualities of the underarm perspiration pad.

[0049] The foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.

[0050] With respect to the above description, it is to be realized that the optimum relationships for the parts of the invention in regard to size, shape, form, materials, function and manner of operation, assembly and use are deemed readily apparent and obvious to those skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present invention.
