Abstract
A reusable holder for absorbent material for absorbing menstrual flow is made from a liquid permeable inner layer affixed to an outer liquid impermeable layer at the peripheral edges to form a pouch between the two layers. An opening in the inner layer provides access to the pouch so that disposable or reusable absorbent material such as paper or cloth may be placed in the pouch to absorb menstrual flow. After use, the absorbent material may be removed from the pouch via the opening so that the used absorbent material may be disposed of or washed for re-use. Wings extending from the sides of the reusable holder allow the holder to be fastened around an undergarment to keep the holder in place. Alternatively, strings are attached to the reusable holder to allow it to be worn like a g-string.
Description
FIELD OF INVENTION

This U.S. patent application is directed to sanitary pads, and more specifically, to a reusable holder allowing the use of reusable or disposable for absorbent materials for absorbing menstrual flow.


BACKGROUND

Sanitary pads are absorbent items worn by women when they are menstruating. They generally comprise an absorbent portion for absorbing liquid and may also include a mechanism for attachment or holding the pad in place. Sanitary pads may be worn with an undergarment.


In the past, materials such as knitted pads and menstrual aprons have been used during menstruation. Rags consisting of folded old cloth were previously used as well.


The advent of disposable sanitary pads was a marked improvement over the technologies that existed prior. Used primarily in more affluent countries such as those in the western world and in other parts of the world, disposable feminine sanitary pads provide numerous benefits, including hygienic, comfort, ease of use and other benefits. Unfortunately, the one-time use nature of a disposable sanitary pad means that the cost of such pads is relatively high. Manufacturers take steps to reduce cost, but the disposable nature of a one-time use sanitary pad means that users must continually spend money to purchase new pads.


In disadvantaged countries and communities, personal income may be so low that disposable sanitary pads are simply not an option for purchase. Many women in such areas have to use discarded cloths or rags, or must simply improvise a sanitary pad out of materials such as paper, weeds, grass, clothes, or rags, or other such materials. As might be imagined, these materials may not provide a desired level of effectiveness, comfort, or safety. Further, they may not be readily available. Also, even if materials such as cloth or rags available, the lack of clean water in many poor disadvantaged countries prevents these improvised sanitary napkins from being properly washed to allow re-use.


The difficulties experienced by women in these situations may cause them to fail to attend school or work. It is unfortunate that an issue which is so readily solved in more affluent countries presents such difficulties for less fortunate women. A satisfactory solution to this problem therefore is a highly important issue which must be solved. The disclosure presented herein provides an affordable, easy, and cheap to manufacture solution to these problems.


SUMMARY OF INVENTION

The foregoing purposes, as well as others that will be apparent are achieved generally by a reusable pad holder or holder (hereafter, “reusable holder or “holder”) for absorbent materials for absorbing menstrual flow. The holder comprises a liquid permeable inner layer and an outer layer that are affixed together at the peripheral edges to form a pouch. An opening in the inner layer allows reusable or disposable absorbent material such as paper or cloth to be inserted into the pad to absorb menstrual flow. The absorbent material may be removed after use and replaced with new absorbent material. Wings extending from the pad serve to hold the pad in place by hugging or wrapping around a user's undergarment. Alternatively, instead of wings the holder may have strings each end which are tied around the user's waist so that the holder can be worn like a bikini bottom or g-string. Other objects, features, and advantages of the present disclosure will be apparent when the detailed description is considered in conjunction with the following drawings.

DETAILED DESCRIPTION OF EMBODIMENTS OF INVENTION

Various embodiments will be hereinafter described with reference to drawings for the purpose of illustrating the foregoing and other aspects of the disclosure.


Referring to FIGS. 1-4, holder 100 comprises a body 102, an outer layer 103, and a liquid permeable inner layer 106. As used herein, the term “inner” means the direction facing the body of the user while the term “outer” means the direction facing away from the user's body. In the present embodiment, liquid permeable inner layer 106 is a nylon mesh fabric. Alternative materials are polyester, cotton, and natural and synthetic fiber mesh. Outer layer 103 is preferably liquid impermeable. In the present embodiment, outer layer 103 is made of waterproof nylon fabric. Alternative materials are polyester, polyurethane, and any natural or synthetic fabrics that are laminated to or coated with a waterproofing material.


Inner layer 106 is coupled, joined, or affixed to outer layer 103, along a peripheral track 118, over a central portion 116 of the body 102, such that a pouch 115 is formed above central portion 116 and between the inner and outer layers 106, 103. In the present embodiment, inner layer 106 is joined or affixed to outer layer 103 by a sewn joint. Other methods such as gluing, heat, or fabric adhesives may also be used.


Inner layer 106 has an opening 119 such as a slit which provides access to pouch 115 for insertion of an absorbent material 120. (FIGS. 1-4) The liquid permeability of inner layer 106 allows for liquid to flow through inner layer 106 into absorbent material 120 while holder 100 is in a worn position. Specifically, absorbent material 120 absorbs menstrual flow and other fluids when holder 100 is in position in an undergarment 162 (FIGS. 5-6) such as a pair of panties. Opening 119 also allows for the removal of absorbent material 120 (e.g., toilet paper) for disposal after use. Alternatively, if the absorbent material 120 is cloth or other washable material, the soiled cloth may be removed for cleaning and re-use. Opening 119 and pouch 115 allows the user to insert and remove any absorbent material into pouch 115. Examples of absorbent material 120 are cloth, paper (e.g. toilet paper), gauze, and processed/pretreated absorbent natural fibers such as banana bark, sisal, and cotton.


A lining 121 (FIGS. 1-3) is also provided around the periphery of holder 100. Lining 121 is provided to ensure a comfortable interface between holder 100 and the wearer, and helps to prevent any irritation which may be caused by contact between any rough edges of holder 100 and the wearer. Lining 121 preferably traces the perimeter of holder 100, including wings 104. In the present embodiment, lining 121 is made of cotton although other natural materials which provide similar functionality such as rayon, linen, silk, or man-made fabric alternatives such as Lyocell and Modal® may also be used.


The holder 100 may be held in place by the use of wings 104 extending from central portion 116 of body 102. Wings 104 preferably have a clasping or attachment mechanisms 114 such as Velcro®, buttons, snaps, hook and loop fasteners or other similar devices. In the present embodiment, the attachment mechanism is Velcro®. Attachment mechanism 114 allows holder 100 to be held in place while worn. Preferably, wings 104 are wrapped around a portion 164 of an undergarment 162 and attachment mechanism 114 is engaged to keep the holder 100 in place. (FIGS. 4-6) This position is called the closed position 180 and is shown in FIG. 6. The open position 160, in which wings 104 are not engaged is shown in FIG. 5. In the present embodiment (FIG. 3) wings 104 are extensions of outer layer 106 and inner layer 103 from central portion 116 of body 102 wherein the extension of inner layer 103 is tucked between the extension of outer layer 103.


In an alternative embodiment (FIGS. 8-9), if the wearer or user does not have access to undergarments, the wings may be replaced by two long strings 202, 204 attached respectively to a front end 206 and a back end 208 of a holder 200. Strings 202, 204 are tied around the waist of the wearer or user so that holder 200 can be worn like a G-string or bikini bottom.


Although the invention has been described with reference to preferred embodiments, it will be appreciated by one of ordinary skill in the art that numerous configurations and modifications are possible in light of the above disclosure. All such variations and modifications are intended to be within the scope of the invention.
