DETAILED DESCRIPTION OF THE INVENTION

[0017] The present invention relates to a wicking and absorbent permeable liner with fluid release method made for wearing in conjunction with other absorbent feminine hygiene items.

[0018] This present invention is of a wicking and absorbent liner comprising a body-facing side, and garment-facing side, and one or more fluid absorbent core layers. The body-facing and garment-facing surface are permeable to menstrual flow and fluids. The body-facing surface is meant to wick away the flow and fluids from the woman's body. The one or more fluid absorbent core layers are meant to absorb and hold the flow and fluids before it is released through the permeable garment-facing surface. The permeable garment-facing surface is meant to allow the flow and fluids to be released freely into an absorbent feminine hygiene item. The liner may comprise of organic or non-organic disposable materials, or made of organic or non-organic cloth or other washable materials. The absorbent liner in this present invention is not limited to one thickness, but may comprise of one or more fluid absorbent core layers to produce absorbent liners with varying thicknesses and absorbability as to satisfy the need to absorb a light, medium, or heavy menstrual flow, or other bodily fluids.

[0019] The liner in this invention is designed and configured to fit between the genital area of a woman and the body-facing part of an absorbent feminine hygiene item. This liner is meant to fill the gap often found between an absorbent feminine hygiene item and a woman's body, and is meant to substantially maintain contact with the labial and genital area of a woman, and in doing so, is meant to improve the absorption rate by wicking the menstrual flow and fluids, improve the collection and absorption of said flow and fluids, and improve the direction of said flow and fluids by releasing the said flow and fluids to the wanted end-point which is an absorbent feminine hygiene item. The said liner is meant to be worn on top of the longitudinal body-facing part of an absorbent feminine hygiene item, and be worn on top of the crotch area of a menstrual panty.

[0020] The body-facing side is meant to be worn body facing. In one embodiment, the body-facing surface may be made of soft, non-irritant fluid permeable material, and may or may not be attached to the one or more fluid absorbent core layers. In another embodiment, the body-facing surface may be an extension of the upper-facing fluid absorbent core layer, forming one unit with the one or more fluid absorbent layers. In another embodiment, the body-facing surface may be attached to the garment-facing surface, forming one surrounding unit around one or more fluid absorbent core layers. The body-facing surface is meant to gently press on the outer labia, without penetrating the inner labia as to not dehydrate and irritate the sensitive inner labia. In some embodiments, because of the pliability and softness of the said absorbent liner, the absorbent liner is capable to comfortably adapt to the configuration of the woman's genital area. These above-mentioned embodiments are just some of the possible versions of this invention and should not be construed as being limited to.

[0021] The garment-facing side is meant to be worn garment facing. In one embodiment, the garment-facing surface may be made of soft, non-irritant permeable material, and may or may not be attached to the one or more fluid absorbent core layers. In another embodiment, the garment-facing surface may be an extension of the lower-facing fluid absorbent layer, forming one unit with the one or more fluid absorbent layers. In another embodiment, the garment-facing surface may be attached to the body-facing surface, forming one surrounding unit around one or more fluid absorbent core layers. The garment-facing surface is meant to be worn on top of an absorbent feminine hygiene item, or worn on top of the crotch area of a menstrual panty. In some embodiments, because of the pliability and softness of the said absorbent liner, the absorbent liner is capable to adapt to the configuration of the absorbent feminine hygiene item. These above-mentioned embodiments are just some of the possible versions of this invention and should not be construed as being limited to.

[0022] In one embodiment, the garment-side of the absorbent liner includes one or more adhesive material strips, dots, circles or semi-circles. The adhesive element added to the garment-facing surface is situated as to not interfere, or if so minimally, with the release of the flow and fluids into an absorbent feminine hygiene item. In another embodiment, the method of attachment of the absorbent liner to an absorbent feminine hygiene item can comprise, but not limited to ties, loops, snaps, buttons, fabric hook and loop fasteners.

[0023] In the said embodiment where the garment-side of the absorbent liner includes one or more strips, dots, circles or semi-circles of adhesive material, these said adhesive elements are covered by one or more protective strips, such as but not limited to, what is known to the art as release strips. These release strips, which may be in the form of a strip, a dot, circle or a semi-circle are added to cover the adhesive element(s) to protect them before use. The adhesive strips are put into place as to ensure that no adhesive enters in contact with the woman's body.

[0024] The adhesive element, or elements, may be situated either at the center of the garment-facing side of the liner, or at the sides of the garment-facing side of the liner, or at each ends of the garment-facing side of the liner, or a combination of these above-mentioned placements.

[0025] The adhesive element, or elements, of the liner is put into place as to attach the liner to the body-facing part of absorbent feminine hygiene items, or on the crutch area of absorbent menstrual panties.

[0026] Because most absorbent feminine hygiene items are intended to be worn within a pair of panties and/or undergarments, they are made relatively small and particularly narrow to accommodate the fit, and due to their inherent small size, they make it hazardous for the menstrual flow and bodily fluids to adequately reach the surface of these absorbent feminine hygiene items. Furthermore, the woman may misjudge the placement of such a sanitary napkin, and in so doing compromise the satisfactory collection and absorption of the menstrual flow and bodily fluids, allowing leaks and leaving the woman with soiled garments.

[0027] The liner in this present invention prevents unwanted menstrual flow and fluids leaks caused by the inherent narrowness of most absorbent feminine hygiene items, especially during a heavy menstrual flow, or a sudden release of flow when a woman gets up after having sat for a while, or having laid down. The said liner wicks the menstrual flow and bodily fluids through its body-facing permeable surface as soon as the said flow reaches the outside labial area of a woman; then the said liner absorbs the wicked menstrual flow and fluids within its one or more fluid absorbent core layers; then the said absorbent liner leads and releases the flow and fluids through its garment-facing fluid permeable surface to the center surface of an absorbent feminine hygiene item, reducing the risk of the menstrual flow to leak to the side, or sides, of the absorbent feminine hygiene item. Furthermore, the said liner in this invention absorbs the menstrual flow into its one or more fluid absorbent core layers before the said flow and fluids is released to the absorbent feminine hygiene items through its garment-facing fluid permeable surface, adding to the lifecycle of the absorbent feminine hygiene items; the woman can replace the said liner many times before having to replace the absorbent feminine hygiene item she is wearing.

[0028] Not only does this present invention helps protect women against having their menstrual flow and bodily fluids to leak from their absorbent feminine hygiene items of choice into their clothing, it also allows women to use their favorite absorbent feminine hygiene items, no matter the abundance of their flow. This invention allows women to no longer be limited to wear super tick, long and absorbent feminine hygiene items during their heavy menstrual flow days; they can use a thinner, slimmer, less invasive absorbent feminine hygiene item, therefore can continue to wear their tight-fitting clothing even during their heaviest menstrual flow days. This invention offers women a unique versatility in the absorbent feminine hygiene items they wear, in an industry that otherwise limits women to use a specifically designed absorbent menstrual pad dependent on their menstrual flow.
