GLASSMAN miga/T@ United States Patent Giice 3,343,543 Patented Sept. 26, 1967 3,343,543 SANITARY NAPKIN Jacob A. Glassman, 1680 Meridian Ave., Miami Beach, Fla. 33139 Filed June 10, 1964, Ser. No. 373,987 3 Claims. (Cl. 12S-290) This invention relates to improvements in sanitary napkins and is specifically concerned with such a napkin embodying structural features that insure total usage of all absorbent portions thereof.

Heretofore, such napkins have been provided with an exterior shield on its bottom face and side edges only intended to serve as a barrier to prevent strike through and spill-over of menstrual wastes. Applicant has established that when worn, such a napkin assumes a lateral cross-sectional shape of an inverted U. As a consequence, the uncovered side margins of the top surface of the napkins thus folded come into contact with the wearers thighs and menstrual wastes are diverted laterally directly onto the thighs long before the napkin becomes saturated. This results in a feeling wetness and the wearer discards the partially used napkin.

The present invention overcomes this objectionable characteristic of the known napkin discussed hereinabove by the presence thereon of a moisture impervious shield that covers the bottom surface, the side edges and the longitudinal margins of the upper surface. Thus, when the napkin is worn and is distorted, when in place, into an inverted U-shape, there is a barrier on the marginal surfaces contacting the thighs hence, there is no spillover or strike through, or feeling of wetness Distribution of menstrual wastes throughout the entire body of the napkin is aided materially by providing the central uncovered area of the top surface of the napkin with one or more longitudinal grooves or slits which acts as troughs to receive and contain menstrual wastes during the period of absorption. As a consequence, the menstrual wastes initially flow longitudinally along the grooves or slits and are absorbed in a downward direction during such flow over the entire length of the napkin. This assures complete and total utilization of the entire body of the napkin.

It is therefore an object of the invention to provide a novelly constructed sanitary napkin.

Another object is to provide a napkin of the character described with novel means to prevent the wearer from experiencing a feeling of wetness Another object is to provide a sanitary napkin with novel means to insure total utilization of its absorptive capacity.

Another object is to provide in a sanitary napkin, one or more longitudinal troughs in its top or body contacting surface.

Another object is to provide a sanitary napkin of the character referred to which is not expensive to manufacture, is readily deformed when in use and is very efcient.

The structure by means of which the above noted and other advantages and objects of the invention are attained will be described in the following specilication, taken in conjunction with the accompanying drawings, showing preferred illustrative embodiments of the invention, in which:

FIG. 1 is a perspective View of an improved sanitary napkin, showing part of its exterior covering broken away.

FIG. 2 is an enlarged transverse sectional view taken on line 2-2 of FIG. 1.

FIG. 3 is a sectional view similar to FIG. 2, showing the sanitary napkin in use.

FIG. 4 is a sectional view of the napkin in the position assumed while being worn.

FIG. 5 is a perspective view of the napkin in the position assumed while being worn.

FIG. 6 is a transverse sectional View of another embodiment of the napkin.

FIG. 9 is a sectional view of the FIG. 8 napkin, while being worn.

FIG. l0 is a transverse sectional View of another embodiment of the invention.

FIG. ll is a sectional view of the FIG. l0 embodiment, showing it in a position of use.

The sanitary napkin, illustrated in one embodiment in FIGS. 1 through 5, is comprised of a substantially rectangular ilat body 11 of highly absorbent material such as cotton, crepe Wadding or other librous material. This body may be in one piece or it may comprise superposed layers of such materials. The body is partially enclosed in a moisture impervious covering 12 which may comprise a sheet of plastic or other water proofed material or, if preferred, may be provided in the form of a sprayon coating. In the latter instance it is preferred to use methacrylate resin in ethyl acetate, employing dichloromonofluoromethane and tricloremonouoromethane as propellants or some other effective colorless plastic spray materials including cellulose acetate butyrate in an acetone solvent, and co-polymers of hydroxyvinylcloride acetate in an ethyl acetate-acetone solvent.

Irrespective of the specific material used or the manner of its application, the non-absorbent impervious covering 12 is provided across the entire bottom surface of the absorbent body 11, over both longitudinal side edges thereof and over the longitudinal margins of its top surface. It is intended that the marginal areas covered by said covering constitute not less than 2/3 of the body width. That is, each margin covering 12a has a width substantially equal to one-third of the body width leaving a central area 11a of about one-third uncovered.

The body 11 with its attached moisture impervious coating 12 is enclosed in a layer of crepe paper 13 of a kind that is highly absorbent and longitudinally grooved and the whole is then enclosed in a thin layer of open mesh fabric 14, such as gauze, which fabric is of a length greater than the length of the body so as to provide end portions 1S useful for attaching the napkin to a support belt or the like. The free edges of the wrapped around gauze 14 are overlapped, as at 14a, slightly in -the top central longitudinal tarea of the napkin.

It has been established that when a napkin is arranged in an in-use position, as shown for example in FIG. 3, it assumes substantially the shape of an inverted U, the exact degree of folding being determined by the spacing between the thighs 16 of the wearer. When this folding occurs, the covering 12a on the top margins of the body are disposed toward and in opposition to the thighs and there can be no strike-through of liquids or blood sidewise through the napkin and onto the thighs.

In order to enhance the rate of absorption by the napkin body, novel mea-ns is provided to insure that menstrual fluids deposited on the top central portion 11a of the body are spread rapidly throughout the length thereof while being retarded against flowing laterally toward the sides. This is best accomplished -by providing, in the exposed top surface 11a of the body, one, two or more longitudinal troughs 17, which troughs terminate short of the ends of the body. More specical'ly, these troughs may be formed by mechanical compression of the body of the napkin or by cutting slits therein at the time of its manufacture so as to form longitudinal grooves or surface slots therein. Similarly, the crepe paper 13 overlying the troughs is longitudinally grooved to lie therein. All menstrual fluids owing into the trough or troughs flows in a longitudinal direction toward the ends of body 11 and is labsorbed directly from the top surface downwardly into the mass of the body and over its entire length by capillary attraction and gravity. A layer or layers of longitudinally wrinkled or grooved absorbent crepe paper 18 is arranged in the body of the napkin between its upper and lower faces to retard ilow of uids to the Ibottom region thereof. This insures total absorption by the upper region before a material quantity of the waste fluids reaches and is absorbed -by the lower portion. Preferably, the layer 18 is narrower than the width of the napkin.

=Fluid absorption =by the napkin is accomplished without loss of fluids laterally as occurs in napkins of known construction owing to the invariable creation of lateral wrinkles 19 (FIG. 5) generated when the napkin is curved longitudinally lbeneath the wearers body. When the napkin is worn the overlapped ends 14a of the outer covering 14 spread apart and the central trough 17 functions to intersect such wrinkles thus converting lateral spread to longitudinal spread.

Y Utilization of the full capacity of the body of the pad, without spill-over or strike through at the effective sides, greatly increases the luseful life of the sanitary napkin and increases user satisfaction. Such full capacity absorption has been established by in-vivo tests which clearly demonstrated that menstrual fluids deposited on the central one-third of the top surface of the napkin disperses in a longitudinal direction along the trough or slits and thus is absorbed over the entire length of the body and into the total mass of said body.

In order to insure that, when applied, the napkin assumes the desired inverted iU-shaped configuration easily, applicant provides also a grooved or otherwise weakened zone in the longitudinal center of the bottom face of the napkin body. This is shown as a compression formed groove 21 which may or may not include the moisture resistant covering 12. Such weakening as =by groove 21 reduces the resistance to folding into inverted U-shape, and increases wearer comfort.

In the FIG. 6-7 embodiment there is provided in the top longitudinal center of the body 11 a wide trough 17a that lies against and conforms to the wearers vulva so as to insure central longitudinal How of menstrual fluids. In other respects the sanitary napkin shown is like the one discussed hereinabove and like numerals identify corresponding parts.

'I'he FIG. 8-9 structure is similar to that shown in FIG. 2, except that here the two side grooves are formed by deep cut slits 17b. When this napkin is worn, the slits open up as shown in IFIG. 9, to insure that the central grooved portion fits snugly against the vulva of the wearer. Like numerals have been used to identify parts corresponding to those in the FIG. 2 disclosure.

In the FIG. l() and 11 disclosure, there is illustrated a napkin which, when worn, forms a longitudinal tampon. As shown, the top uncovered central region of the napkin is formed with a pair of laterally spaced longitudinal slits 17C. When the napkin is worn, as shown in FIG. 11, the medial portion between slits 17C projects into the vaginal cleft to receive menstrual uids before it leaves the vulva.

' Although I have described preferred embodiments of my invention, in considerable detail, it will be understood that the description thereof is intended to be illustrative, rather than restrictive, as many details of the structures disclosed may be modied or changed without departing from the spirit or scope of the invention. Accordingly, I do not desire to be restricted to the exact constructions described.

I claim:

1. A sanitary napkin comprising a at substantially rectangular mass of fluid absorbent material having a body contacting top surface, a bottom surface and side surfaces; a fluid resistant barrier overlying the bottom surface, the side surfaces and longitudinal marginal areas of the top surface; each longitudinal marginal area cornprising approximately one-third the width of the absorbent mass so as to leave the longitudinal medial portion of the top surface uncovered; and a pair of longitudinal laterally spaced grooves in said medial portion, said grooves terminating short of the ends of said mass and defining between them an area that will protrude from the top surface of the mass in the form of a ridge when the mass is folded along a medial longitudinal line into an inverted U-shape.

2. The napkin recited in claim 1, in which a thin layer of loosely woven material is wrapped around the absorbent mass with its longitudinal meeting edges normally overlying said medial portion of the top surface of the mass.

3. The napkin recited in claim 1, in which a 1ongitudinal groove is present in the bottom surface to facilitate longitudinal folding.
