This invention relates to catamenial pads and more generally vto ‘sanitary bandages to be worn gravity. I have also found by actual tests and the study of the female anatomy that it is un necessary for the pad to extend beyond the rear end of the Derineum'or to be of too great a width at this point because of the natural relations. On the basis of this knowledge I have devised a catamenial pad, which is a radical departure from conventional pads now in universal use but f by women during the menstrual period or by which provides the same degree of safety as said those subjected to vulva, vaginal, or uterine dis-`> 10 conventional pads, and at the same time elimi charges. j ' ' l At thepresent time .'(and for a great many years in the past) the most common form of sani cessive bulk of said conventiona1 pads. ' According to the principles of the present infA tarypad or napkin commercially available for use vention, the absorbent pad is given a predeter by women during the menstrual period consists mined shape such that it substantially conforms of a generally oblong, arcuate ended pad of ab sorbent material enclosed in a sheet of loosely woven gauze. These pads are of standard di the body inthe region of the female genitalia mensions, approximately 9 inches longrand 3 ` nates al1 chañng and discomfort due to the ex in contour with the natural anatomical curves of comprising the thighs, buttocks andperineum parts; Furthermore, the pad is considerably inches Wide' for adult use (the “junior” size being 20 shorter than conventional pads land is made ofk > slightly smaller). In view of their configuration such length that it is adapted to be worn with its and width such pads inherently cause consider rearmost region terminating at the anal aperture able discomfort to the wearer, and very often and its forwardy region terminating at a‘point chañng, due to the fact that they must be worn` slightly beyond the mons Veneris'. laterally compressed, or “bunched,” or “packed” The principal advantages of the present inven between the thighs. Moreover, due to theirI tion, obviously, are two-fold. First, all discom length, theyY extend rearwardly of the rectum a fort tothe wearer from the pad per se is definite considerable 'distance and produce a “wad” at the' Y ly eliminated, and, secondly, the pad can be man’ rectum whichfcreates a source of continuous dis ufactured at a substantial saving due to the fact comfort, particularly when the wearer is seated. that at least 30% less absorbent material is re This wad not only causes discomfort, but dise quired. Additional and commercially important torts the natural anatomical relations around the advantages arise from the'fact that less gauze vulva and anus. These disadvantages have long is required to wrap the absorbent pad, smaller been known and tolerated because they were thought to be inescapable. It is true, that long cartons may be used in shipment and the recognition of the problem has brought forth numerous suggestions and variations in sanitaryV napkin construction but none of these has been to the smaller weight and bulk of the product. Still greater economy can be effected by eliminat commercially adopted toY supplant the well known, conventional form of catamenial pad. The above mentioned width and length of con ventional catamenial pads and their customary manner of being worn have been predicated upon the belief that it is essential to have a substan tial portion of the pad extend rearwardly of the rectum in order to absorb the material discharged from the uterus, etc., it being thev common and generally accepted belief that the discharged ma terial travels ' downwardly and rearwardly through the pad by gravity. `I have discovered f that, contrary to thek foregoing generally ac cepted belief, the absorbing action of the pad is such that it causes the discharged material to travel forwardly and upwardly by capillary ac tion rather than downwardly and rearwardly by 5a shipping costs themselves materially reduced due ing the gauze altogether, as will appear more fully _ hereinafter. Another novel feature of the present catame nial device isvthe incorporation therein of a sup porting strip of predetermined ,width which ex tends longitudinally ofl the absorbent pad along the lower side thereof and which is adapted to maintain said pad laterally substantially flat and thereby prevent roping and twisting of said pad. In» one formv of the invention the pad and sup porting strip are enclosed in a gauze sheet or en velope, and in accordancewith another form of the invention the longitudinal edges of the gauze sheet are so overlapped as to provide in effect a “built in” longitudinal band rendering the use of a separatefsupporting strip unnecessary. ' A further rfeature of the invention resides in 2,408,508 3 substantially along line G-S of Figure 5; Figure 7 is a plan view of the catamenial de catamenial pad. A still further feature resides in the provision of an improvement in catarnenial pads to render such pads non-chañng even during body move vice shown in Figure 5, except for the gauze en velope which is opened to expose the absorbent pad normally confined therein; Figure 8 is a diagrammatic, dimensioned, view ments caused by walking that normally results in chañng caused by friction with the natural anatomical curves of the body in the region of the female external genitalia comprising the thighs, buttocks, and peri-anal parts.

Another object of the invention is to improve the construction of catamenial pads by providing features that preclude chañng to the wearer. Another object is to provide a catamenial pad ventional pad element to facilitate comparison in size and shape; Figure 9 is a top plan View of a modified em bodiment of the catamenial pad shown in Figure 5 with the bottom gauze sheet of the envelope opened to clarify the showing of a moisture proof lower region to prevent striking through; Figure 10 is a transverse sectional view through a pad of the type shown in Figure 9; Figure 11 is a plan view of a catamenial device having the enclosing gauze sheet so folded along 20 anatomical curves of the body in the region of the underside vof the -pad as to eliminate the use the female external genitalia comprising the of the supporting strip shown in Figures 5 and 9; thighs, buttocks and perineum occurring in the Figure 12 is -an exaggerated cross-sectional View relatively changing positions of the body occa of only the gauze sheet of Figure 11 illustrating sioned in walking and other movements. one manner in which said gauze sheet may be Still another object is to provide a catamenial folded to provide a plurality of layers of fabric pad with a non-chai'lng finish affording the wear at the underside of the pad adapted to serve as er increased comfort through the elimination of a substantially non-stretchable supporting band; skin iniiammation in the contact regions of the Figure 13 is a view similar to Figure 12 illus female external genitalia, thighs and perineum. A further object is the provision of a cata 30 trating another manner of folding the gauze possessed of improved non-chañng features to eliminate frictional edge contact with the natural menial pad envelope compositely incorporated with a moistureproof substance to afford smooth sheet; Figure 14 is a dimensioned plan view of a slightly modified form of pad element; non-chañng contact with the adjacent contour Figure l5 is a view of the lower side of another of the female parts and thus afford greater phys e: Ul pad construction embodying the principles of the ical comfort. present invention in which the gauze wrapper is A still further object is the provision of a only of slightly greater length than the absorb catamenial pad envelope compositely incorpo ent pad and in which the supporting strip or rated with a moistureproof substance that pre band is adhesively secured to the pad; cludes the possible striking through of the men Figure 16 is an enlarged view of the absorbent strual flow under conditions that are sometimes 40 pad and'gauze wrapper shown in Figure l5; beyond the control of the wearer.

An additional object is to provide a catamenial fit ment of the invention wherein the gauze wrapper pad envelope compositely incorporated with a moistureproof substance to prevent menstrual excretion from striking therethrough and pro vide non-chafing body contacting surfaces con ducive to added physical and mental comfort of the wearer.
