JEANETTE ELAlNEJ-MOSIER BY Maw/m4 swim/M Affame s Patented Jan. 15, 1953 3,073,309 SELF-SUPEORTING SANlTARY NAPKIN Jeannette Elaine J. Mosier, Albuquerque, N. Mex. (606 Ocean Blvd., Seal Beach,tla:ir'.)

Filed Nov. 7, 1900, Ser. No. c7588 9 Claims. (Cl. nth-2%) The present invention relates to a catarnenial appliance and more particularly to an improved sanitary napkin and holder.

Present-day catamenial devices frequently incorporate belts which are diflioult to adjust so that they are comfortable in the various positions the body assumes in standing, sitting, jumping, bending, etc. Such belts otten cause chafing and irritation of the perineal and intergluteal areas. Also, such sanitary belts, in many cases, tend to allow the sanitary napkin to slide out of its most absorptive position.

Frequently, emergencies occur at such places as movies, restaurants and on Week end vacations in that the menses begin at unexpected times. Obviously, it is undesirable to be required to carry the standard sanitary belt at all times. Emergency sanitary napkins are available but for various reasons, have been found to be unsatisfactory in one way or another. Consequently, a primary object of the present invention is to provide an improved sanitary napkin and supporting means which can be readily dispensed by a restroom vending machine.

A further object of the present invention is to provide an improved catamenial appliance.

Still another object of the present invention is to provide an improved holder for use with an sanitary napkin, said holder being sufliciently small and light to be easily package in combination with a sanitary napkin for dis pensing by a vending machine.

Still another object of the present invention is to provide an improved holder and sanitary napkin combination, said holder being suflficiently inexpensive that the used napkin and holder can be both be thrown away or disposed of similarly to conventional sanitary napkins.

Still another object of the present invention is to provide a self-supporting sanitary napkin which allows relatively complete freedom of movement with relatively little chafing or irritation of the skin.

Another object of the present invention is to provide a self-supporting sanitary napkin constructed to eliminate irritation and binding between the buttocks.

Related objects and advantages will become apparent as the description proceeds.

In accordance with the present invention, one specific embodiment thereof comprises an elongated, rectangular pad of absorbent material having elastic cord passing therethrough and extending from the opposite longitudinal sides thereof to form loops. The elastic cord is arranged to lead away from each longitudinal side of the pad at the ends of each side and, in other words, at the corners of the pad. The loops are of a suitable size or length so as to be received in stretched relation about the legs and so as to surround each leg at the junction thereof with the torso.

The full nature of the invention will be understood from the accompanying drawings and the following description and claims:

FIG. 1 is a perspective view of a portion of the female body showing a self-supporting napkin of the present invention in proper position.

' FIG. 2 is a perspective view of a self-supporting sanitary napkin embodying the present invention.

FIGS. 3 6 are views similar to FIG. 2 of alternative embodiments of the present invention.

FIG. 7 is a perspective view of the self-supporting sanitary napkin of FIG. 4 showing the rearward or outer Surrace of the napkin and indicating in what manner the stitching of the various illustrated embodiments can be accomplished.

KG. 8 is a sectional view of the napkin and holder of HG. 1 showing it in position over the vulvar area.

Referring now to the drawings and more particularly to EU. 2, there is illustrated a self-supportingsanitary napkin 10 which includes a generally rectangular, somewhat elongated napkin or pad 11 composed, for the most part, of gauze or similar cellulose material conventionally used in sanitary napkins. Passing thrOugh the pad and extending from the opposite longitudinal sides :12 thereof is a pair ofloops 13 formed of highly stretch able, standard, commercially available, elastic thread Or cord. In the particular embodiment illustrated in H6. 2, the cord of each loop passes through the pad adjacent thelongitudinal side 12 which is on the same side of the pad as the particular loop.

Referring now to H68. 1 and 8, it should be noted that between the legs, the female thigh is narrowed at the groove between the lateral margin of the labia majora and the proximal portion of the internal femoral region, this groove being called the genito-crural fold. Theloops 13 are of a suitable size to be received in stretched relation about the thighs adjacent the junction thereof with the torso. Because of the narrowing of the female form as above mentioned, theelastic loops 13 may be seated securely to encircle the thighs so that the edge of the pad Ill is seated securely in the above mentioned groove and the loops extend through the gluteal fold, and laterally just above the trochanteric region, anteriorly across the subinguinal regions just above the medial termination of the inguinal ligament and again to the pad at the genito-crural groove. When the self-supporting sanitary napkin of the present invention is so received on the female form, it is comfortable and causes little or no skin chafing or irritation.

The pad 11 is stitched on theface 15 thereof to cause a portion of the pad to extend upwardly away from theface 15 and to form an elongated fin-like projection 16. It should be noted that means other than stitching can be used to form the projection 16. This projection extends parallel to the length of the pad forwardly from the rearward end thereof, is located centrally with relation to the width of the pad and has a length approximately equal to the distance between the rectum and the frenulurn. This type of projection is more thoroughly described and claimed in my copending application of Catamenial Appliance filed on May 9, 1960, Serial Number 27,737, it being understood that this previous application discloses a somewhat diiferent type of holder and pad for use with such a projection.

The projection 1-5 bears against the wearer and i 'seated as shown in FIG. 8 between the frenulum l7 andrectum 18. This projection acts as an indicating device giving confidence to the wearer and assuring her that the napkin is in proper position, yet does not result in the irritation which may result from the conventional tampon or devices extending into the vestibule area between the labia. When the wearer is lying in a horizontal upwardly facing position as in sleep, the projection 16 provides an effective damming action deterring rearward seepage of fluid and preventing soiling of the clothes.

Even though it is preferred that the projection 16 will terminate in the same plane as the posterior end 2d of the pad, it should be understood that the design of the present pad is flexible and the fin-like projection may extend posteriorly beyond the end 28' or may extend slightly anteriorly thereof. A specific embodiment of the present invention would include a fin-like projection 16, the forward end 21 of which begins approximately one and one-fourth to two inches from the posterior end of the pad, the projection rising from the surface of the pad to :1 highest level at the posterior end of the projection where it extends approximately one-half to one inch from the surface of the pad. in vertical transverse section, the projection 16 is generally triangular shaped and is slightly wider at its b c than at its most distal portion.

The this ss or the particular pad disclosed in PEG. 2 is preferably about onc-l'ialf to three-fourths of the thickless of a standard sanitary napkin but it should be understood that the pad can be of any desired thickness. The length of the particular pad disclosed in FIG. 2 is pref-erably from four to six inches. Obviously, this length is quite a bit less than the length. of a standard sanitary napkin and this is made possible by the fact that the pad of FIG. l has incorporated therein a small liquid permeable container 22 within which is received a special absorbing material capable of forming a gel with menses. This container may, for example, be formed of folded tissue paper or the like and has received therein, by way of specific example, 5 cc. of a granulated material including 28% gelatin, 17% agar-agar and 55% common sugar by volume and in a simple mechanical mixture forming a random matrix. Because of the fact that this special absorbing material has very high absorptive and retaining powers, thenapkin 12; may have a much smaller size and may contain a much smaller amount of cellulose material than conventional napkins and may be easily flushed down a toilet without clogging plumbing.

Various alternative gel-forming mixtures can be used in place of the above described preferred mixture, for example, the sugar mentioned above might be replaced by another carbohydrate or even by a salt such as, for example, sodium chloride. In the special absorbent composiof the present invention, the gel-forming substance or principle is chiefly responsible for the absorption of menstrual fluids, the water soluble carbohydrate being present as an inert non-absorbing substance whose function is to maintain the maximum amount of surface of the gelforming substance available for the absorption of fluids. For example, when a matrix of gel-forming substance and carbohydrate is formed prior to the incorporation of the mixture into a catamenial device, the more rapid solubility of the carbohydrate component causes it to dissolve out of the preformed matrix, thus continuously exposing fresh absorbing surfaces of the gel-forming component of the matrix.

Referring to FIGS. 36, there is disclosed various alternative embodiments of the present invention. In PEG. 3, each elastic cord and 25A extends into thepad 26 at thecorners 27 and 27A thereof but extends longitudinally of the pad along a longitudinal edge portion 3% which is opposite to the longitudinal edge portion adjacent which the loop of the particular cord is located. The particular embodiment of FIG. 3 includes aprojection 31 similar to the projection 16 as do all of the embodiments of the present invention as disclosed in FIGS. 26.

In FIG. 4, the supporting means of the pad is a single length ofcord 35 which extends through the pad at theopposite end portions 36 thereof. In the particular embodiment disclosed in FIG. 5, a pair of elastic cords 4t) and 40A extend into thepad 41 at the corners of the pad and at theends 42 of each respective longitudinal edge portion. Each of the elastic cords passes diagonally through the pad and is visible at 45 on the opposite longitudinal side portion from its particular loop. In FIG. 6, an embodiment is disclosed in which theelastic cord 45 has generally the shape of a figure 8. It should be understood that in each of the embodiments disclosed in FIGS. 26, the elastic cord or thread extends from the opposite longitudinal sides of the pad to form loops and also extends from each longitudinal side at the ends thereof or in other words, at the corners of the pad.

Referring to FIG. 7, the particular stitching used in constructing the embodiment of FIG. 4 is illustrated. In this embodiment, theelastic cord 35 passes into and out of the pad 36 a number of times in order to securely attach the cord to the pad. It should be noted that the cord is located on theface 37 of the pad which is away from the body when the pad is in use. This arrangement eliminates irritation and chafing of the body by the cord.

From the above description, it can be appreciated that the present invention provides an improved supporting means for a sanitary napkin, said supporting means being small, inexpensive and easily packaged whereby it can be dispensed by a vending machine and can be thrown away after use. It can also be appreciated from the above description that the present invention provides an improved self-supporting sanitary napkin which does not include a bulky and irritating sanitary belt extending between the buttocks where it will cause chafing and irritation whereby the napkin of the present invention will be more comfortable in use.

While the invention has been illustrated and described in detail in the drawings and foregoing description, the same is to be considered as illustrative and not restrictive in character, it being understood that only the preferred embodiment has been shown and described and that all changes and modifications that come within the spirit of the invention and the scope of the claims are also desired to be protected. For example, the napkin of the present invention might be modified to eliminate the projection 16 or to eliminate the gel-forming material and the container 22. As a further example, the complete napkin and the projection 16 might contain gel-forming material;

As still a further example, the elastic cord of the present invention might be formed of water soluble material woven in such a way as to provide elasticity. Alternatively, the cord might be formed of interrupted elastic, the interruption being of water soluble paper or string that is easily broken and being located for positioning over the trochanter region.
