Field, RED. 3, Angola, Ind. 46703 Filed July 16, 1964, Ser. No. 383,161 Claims. (Cl. 128-489) ABSTRACT OF THE DISCLOSURE The invention is directed to a sanitary napkin having an elongated absorbent pad provided with a short tab and an extension which is of a length substantially corresponding to that of the pad and tab so that it may be folded under the pad with its free end disposed in juxtaposed relation to a freeend of the tab.
The subject invention relates generally to means for promoting body hygiene and more particularly is di rected to improvements in a sanitary napkin and/or supporting means therefor.
An important object of the invention is to provide a napkin structure which comprises an absorbent pad, provided with means, such as a frontal tab, and rear elongate means, such as a strap, attachment or connection of the napkin to a supporting or body encircling means, such as a belt, in a unique way.
More particularly, an objective of the invention is to provide a napkin of theabove character in which the strap is preferably of a length greater than that of the pad so that a rear portion of the strap may be connected to means carried by back portion of a belt, and the tab and a free end of the strap may be connected to means carried by a frontal portion of the belt whereby, to locate an underlying portion of the strap under the pad for supporting the latter in relation to an appropriate part of the anatomy.
Another object of the invention is to provide a reversible napkin, as above described, in which the pad of the napkin may be of a conventional thickness and width constructed from any material suitable for the purpose, and the tab and strap preferably constitute integral continuations of the fabric or material embracing or carrying the pad.
Further objects of the invention are to provide a napkin which, when properly supported in' relation to the anatomy, offers advantages with respect to greater comfort, additional protection afforded by the underlying absorbent portion of the strap, stability, avoidance of bulging, and ease and speed of assembly and disassembly of the napkin with respect to a belt, as distinguished from conventional napkins and/ or belts.
A significant object of the invention is to provide a napkin of the above description, in which the strap offers an arrangement whereby the napkin may readily automatically adjust itself in conforming relationship to a body through the agency of a slidable or adjustable connection with a unique belt.
A particularly important objective of the invention is to provide an improved napkin structure in which an underlying supporting portion thereof, such as the strap, constitutes an integral portion or a component part of the structure and is of such a character that the complete structure is rendered completely disposable after use.
A specific object of the invention is to provide a napkin of substantially the same general character above described, which is modified by providing an inner surface of the strap with an adhesive which assists in promoting adherence between the strap and an underside of the pad.
Another specific object of the invention is to provide a napkin of substantially the same general character as means affording attachment which assist in facilitating described, which is modified by treating or impregnating an inner surface of the strap with a substance which is impervious to liquid whereby to offer greater protection to the wearer.
Another object of the invention is to provide means preferably in the form of a separate element or member which is comprised of receiving means, such as a container for receiving a portion of a conventional napkin and a strap constituting a continuation of the container for the purpose above described.
An additional object of the invention is to provide an adjustable resiliently flexible belt which is preferably generally preformed or contoured to the shape of a body and includes a relatively small front V-shaped portion and a relatively large rear V-shaped portion which carry or connection of the napkin thereto. More specifically, the front V-shaped portion preferably carries a depending portion to which the tab and the free end of the napkin may be attached and the rear V-shaped portion preferably carries a fastener, such as a loop or ring through which the strap of the napkin may be readily threaded for supporting the rear extremity of the napkin in a relatively low and inset or confined position in the crotch of the body in order to avoid any rear out-bulging of the napkin and fastener, the latter of which frequently results from the use of a conventional napkin. The loop at the rear V-shaped por? tion of the belt avoids use of the conventional pin or fastener which not only requires locking and unlocking or exacting manipulation at an awkward location, but occasionally causes injury and an unsightly appearance.
. A further object of the invention is to provide a unique method or methods of assembling the napkin structure and belt.
Additional objectives and advantages of the invention will readily become apparent after the description hereinafter set forth is considered in conjunction with the drawings annexed hereto.

FIGURE 16 is a transverse section taken substantially on line 1616 of FIGURE 14.
Referring first to the preferred designs and constructions exemplified in FIGURES 1 through 10 of the drawing, numeral 1 generally designates a napkin structure adapted for connection to an encircling means or belt generally designated 2 for disposition about the body of individual 3.
More particularly, the napkin 1 is preferably comprised of an elongated absorbent pad 14 which is carried by or confined within a receiving means 5 preferably in the form of an enclosure or envelope of fluid pervious fabric. The pad and fabric are preferably constructed from any of the well known or conventional absorbent materials currently in use for such a product, but any material suitable for the purpose may be utilized. The pad is preferably made substantially rectangular in shape with rounded ends and uniform as to thickness, width and length, but these dimensions may be modified as desired.
The napkin is preferably provided with a relatively short continuation or flexible tab 6 at its fore or front end and with a relatively long continuation or flexible strap 7 at its rear end. The tab and strap may constitute integral continuations of the receiving means 5 and/or continuations of the pad 4, whichever is desired from a manufacturing standpoint. It is to be understood that the portions 5, 6 and 7 of the napkin may be constructed in different Ways. For example, these portions may be made from a single sheet of rectangular material which is folded or Wrapped into a generally tubular condition about the pad or may be of a sock-like character. It may be stated that, as worn, the receiving means 5 and tab 6 constitute an upper longitudinal portion of the napkin structure which carries the pad and that the strap 7 constitutes a lower longitudinal continuation of the upper longitudinal portion. The strap is adapted to be folded or turned back under the upper longitudinal portion to form a loop 8 at the junction between the receiving means and strap, as shown in FIGURES 1 and 10, and so that a free end 9 of the strap may be brought into abutting relation with the tab as illustrated in FIGURE 2, all of which will be more fully described subsequently. It will be observed that the tab and strap are preferably made relatively thin and narrow as compared to the thickness and width of the pad but, if desired, the strap may be made in any suitable length and width. For example, it may be made as wide as the pad or greater in width so that portions may be disposed in overlapping relationship. Attention is directed to the fact that the strap is preferably of a length which is substantially equivalent to the combined lengths of the pad and tab or is at least of a length suflicient to extend under the pad in supporting relation thereto when the napkin is correctly connected to the belt 2 as depicted in FIGURES 1 and 10.
The strap is preferably of such a size and flexibility that it will engage and readily adjust itself with respect to the resilient undersurface of the pad in a mode whereby to assist in supporting and conforming the pad to the crotch of the body and thereby promote comfort to the wearer.
The belt may be designed and constructed in various ways but, asillustrated herein, it is preferably generally preformed or contoured to embrace the waist of the body 3 and preferably made of elastic or resiliently flexible washable fabric material. It preferably comprises a pair of corresponding side portions 10 and back and front portions. If desired, the side portions may be provided with a pair of adjustable means in a conventional manner whereby the Size of the belt may be readily varied. The
back or rear preferably includes a pair of depending converging portions 11 which are joined to define a relatively large V-formation, the apex or location 12 of which is provided with a receiving means 13 preferably in the form of a depending flexible loop or ring constructed from a desirable strong and washable fabric. It will be observed that the ends of the converging portions 11 are preferably joined at right angles by stitching and that the loop is comprised of a strip of fabric having ends which are secured by stitching in superimposed relation against the inner side of the rear V-formation. The ends of the converging portions and ends of the loop are thus secured in a reenforced relatively thin flat condition. This factor and the use of an all fabric material structure at the V-formation is of considerable important as it avoids the use of metal fasteners, such as pins, which may cause injury and produce a bulge at the rear of the wearer. Obviously, it is not essential that the formations be exactly V-shaped, but it is desirable that at least the back of the encircling means depends so as to properly locate the receiving means 13.
The front of the belt preferably comprises a pair of corresponding depending converging portions 14 which are preferably joined together to define an oblique V- shaped formation which is preferably located at a higher elevation than the back V-shaped formation. The front V-shaped formation is preferably provided with attaching means in form of a depending flexible washable pendant or tab 15, as shown in FIGURES 1 and 4. It will be observed that the ends of converging portions 14 and an upper end of the pendant are preferably joined in a superimposed reenforced flat condition by stitching. The pendant carries a fastener or connector 16 of a conventional character whereby to facilitate connection of the tab 6 of the napkin and the free end of the strap 7 thereto as shown in FIGURES 1 and 10. Obviously, means other than stitching may be utilized to secure portions of the belt, receiving means and pendant assembled.
If desired, the frontal portion of the belt may be provided with a pendant or tab 17 which carries a safety pin 18 whereby to offer .a different conventional means of attaching the tab and strap to the belt.
The napkin structure may be readily attached to the belt in different unique ways, as distinguished from conventional installations :and/ or methods. More particularly, one method, assuming that the belt has already been applied to the body of the wearer, is to pull forwardly on the rear V-shaped formation to locate the loop 13 in a position to facilitate insertion of the strap downwardly to the dotted line position shown in FIGURE 1 and upwardly into engagement with the underside of the pad, preferably at its medial area, in order that the free end 9 of the strap and the tab 6 may be brought into the juxtaposed relation as evidenced in FIGURE 2 for connection with the fastener or connector 16 carried by the pendant 15. Obviously, it may or may not be necessary to stretch the rear formation forwardly as just described. As an alternative method of attaching the napkin structure to the belt, the tab 6 may be first connected to the connector 16, after which the strap may be inserted downwardly through the loop and then brought upwardly in supporting relation with the pad to locate the free end of the strap in a position for final connection with the connector 16. Obviously, the tab and strap may be attached to the connector or pin 18 in lieu of the connector 16, depending on the type of connector employed.
Attention is directed to the fact that the strap assists in supporting and/ or reinforcing the pad as well as promoting its conformance to the crotch of the body. The connection of the strap with the loop 13 is an adjustable or, slidable one and allows the napkin structure to automatially adjust itself with respect to the back of the belt and to the crotch of the body. This adjustable connection also enables the upper and lower longitudinal portions of the napkin structure to automatically adjust themselves with respect to one another or otherwise afford what may be termed a general balancing of such portions between the points or locations of suspension. Of further significance is the fact that the side portions of the belt curvingly merge with the converging portions 11 of the rear V-formation for the purpose of conforming the belt to the waist and buttocks and assist in locating the apex 12 of the formation in a relatively low and inset position with respect to the crotch of the body, the purpose of which is to prevent any bulging or protrusion at the rear of the wearer. Otherwise expressed, the converging portions smoothly engage the back of the wearer and cause a rear extremity of the napkin structure and the structure connecting it with the belt to be inset so that the back of an outermost garment will normally conform to the body without deformation, as distinguished from a conventional arrangement where some bulging usually occurs. The relatively thin compacted condition of the apex area of the belt, flexibility of the loop 13 and its connection with the strap also serves to promote conformity of the assembly to the crotch of the wearer. Furthermore, the strap and loop afford a unique arrangement whereby the strap may be readily inserted and removed from the loop and the strap provides additional absorbent protection to the wearer.
As above referred to and exemplified in FIGURES 11, l2.and 13, the napkin structure 1 may be modified to some extent. For example, as depicted in FIGURE 11, the undersurface of the receiving means and/or pad may be provided or treated with a material 19 which is moisture resistant or impervious to liquid in order to promote retention of any discharge in the pad or otherwise assist in providing a protective shield or guard for the wearer. This organization further assists in maintaining the strap in a dry condition whereby to promote its release from the loop 13. As another example, as shown in FIGURE 12, an upper surface of the strap may be provided or treated with a readily releasable adhesive 20 whereby to assist in holding the strap detachably connected with the unders-urface of the receiving means and/or pad. As a further example, as illustrated in FIGURE 12, the upper surface of the strap may be provided or treated with a material 21 which is moisture resistant or impervious to liquid in order to promote retention of any discharge in the receiving means and/or pad or otherwise assist in providing a protective shield or guard for the wearer.
FIGURES 14, 15 and 16 depict a modified napkin structure which substantially corresponds in size and shape to the napkin structure 1. More particularly, the napkin structure disclosed in FIGURES. 14, 15 and 16 comprises a conventional napkin generally designated 50 and an element generally designated 51. The napkin 50 includes a pad 52 provided with a relatively short continuation or tab 53 at its fore end and an elongate continuation or tab 54 at its rear end. The tabs 53 and 54 may constitute integral continuations of a receiving means 55 which carries or receives the pad 52. The element 51 preferably includes a receiving means 56, preferably in the form of a container or pocket, which is open at its free end as indicated at 57 and an elongate continuation or extension providing a strap 58. The receiving means 56 and the strap 58 are constructed so that the pad 52 and its receiving means 55 are housed in the receiving means 56 and the tab 54 is housed in the strap 58. While frictional forces ordinarily would be sufiicient to hold element 51 in place, the element '51 may be secured to the napkin 50 by any suitable means such as by an adhesive, tying or stitching, so that the element constitutes -a means whereby a conventional napkin may be substantially converted to one embodying the subject invention. It is to be understood that the element 51 may be constructed into a generally tubular condition in various ways. For example, the element may be made from a rectangular piece of material which is folded into a tubular shape for substantially wrapping the conventional napkin 50 or, if
6 desired, it may be of a sock-like character. With this unique organization, the receiving means 56 of the element adds some absorbent material to the pad 52 and receiving means 55 of the conventional napkin and adds reinforcement to tab 54 and strap 58 when brought into supporting relation with the pad 52 and/or receiving means 55.
Having thus described my invention,'it is obvious that various modifications may be made in the same without departing from the spirit of the invention and, therefore, 'I do not wish to be understood as limiting myself to the exact forms, constructions, arrangements and combinations of parts herein shown and described.
