Jan. 1, 1963 G. GARCIA SANITARY NAPKIN Filed Nov. 7, 195e R m N mm M m U G ATTORNEY United tates Patent 3,@'7L13S SANITARY NAPKIN Gustavo Garcia, i3d@ Caiifornia Ave., West Corina, Calif. Filed Nov. 7, 1958, Ser. No. 772,554 14 Claims. (Cl. 12S-290) This invention relates to sanitary napkins used in the practice of feminine hygiene.

Many sanitary napkins presently in use are composed of one or two pads wrapped in a thin gauge-like material. The napkin is arranged to engage against the body of the wearer in the catamenial region, generally being placed within a holder or belt. Although often represented as being easily disposable after use, such napkins, in fact, present to the user a serious disposability problem. Napkins of the construction described afford substantial bulk, incompatible with easy accommodation by the `water closet system found in the average home. Attempts to ilush such napkins after use often result in annoying, inconvenient, and sometimes expensive stoppage of the plumbing. As a result, used napkins must usually be wrapped protectively and disposed of by trash removal or burning.

It is, therefore, the principal object of the present invention to provide an improved sanitary napkin of novel construction affording convenient disposability.

Another object of the present invention is to provide a sanitary napkin that may easily be accommodated by home water closet systems.

Still another object of this invention is to provide a sanitary napkin of composite construction that may easily be separated into its component parts.

And another object, of the present invention is to provide an easily disposable sanitary napkin having improved absorbent quality, which is more comfortable to the wearer, which attenuates fluid odors to a large extent, and which can be easily manufactured for sale at a reasonable price.

In its broadest aspect the present invention comprises a plurality of small softabsorbent pads arranged within a common wrapping cover to form a sanitary napkin of unitary structure. Means are provided for separating the napkin into its small component parts after use. A principal feature of the present invention is the use of a plurality of small absorbent pads of a size affording easy disposability by flushing down the usual home water closet. Use of these small pads provides a napkin having superior absorbent properties as more absorbent surface is exposed to the body of the wearer than with a single pad of equivalent size. Such a composite structure affords more comfort and protection to the wearer, as it is more flexible and may more readily be shaped to the contour of the 4bearing region of the wearers body. Another feature of this invention is the use of a plurality of ilexible strips extending outwardly of the wrapping from the interior of the unitary structure, the terminal ends of which engage pads within the structure. After use, the napkin may be removed by grasping these strips together and imparting the necessary movement thereto. To dispose of the napkin the strips are pulled in opposite directions, thereby unwrapping the cover material and disintegrating the napkin into the component parts and permitting disposal as previously discussed. And an optional feature is the p-rovision of a deodorizing agent which together with the tight lit provided by the flexible structure, attenuates fluid odors to a large extent.

The above and other objects, aspects, features, and advantages of the present invention will become apparent by reading the `following more detailed description and appended claims together with the accompanying drawings, wherein:

FIGURE l is a plan View of the sanitary napkin of the present invention;

FIGURE 2 is a transverse sectional view of the sanitary napkin taken on line 2-2 of FIG. l;

FIGURE 3 is a transverse sectional view of an alternative embodiment of a sanitary napkin constructed according to this invention;

FIGURE 4 is a fragmentary sectional View showing an alternative means of engaging the separation .means with the absorbent pads of the present invention; and,

FIGURE 5 is a view in section of yet another embodiment of a sanitary napkin according to the present in vention.

Reference is made to FIGURES 1 and 2 which show the sanitary napkin 10 of the present invention in a preferred embodiment. A plurality of small absorbent pads, are arranged in two groups, the first group comprising a rst pad l, second pad 2, and a third pad 3, while the second group consists of a fourth pad 4, and a fifth pad 5. A iirst strip 12, which maybe, for example, of folded cheesecloth, engages at its terminal end a surface of one of the pads in the first group, shown here as. pad 1. A second strip 14 engages at its terminal end a surface of one of the pads of the second group, shown here as pad 5. The strips may engage the pads in any of several ways. They may be secured to the terminal pads by fluid-proof adhesive means such as glue. Where the surface of the strips is suciently rough, as where cheesecloth is employed, the frictional engagement between the strip and the terminal pad is suiicient to prevent them from separating when a force is exerted on the strip. This is the method illustrated in FIGS. 2 and 3. The strip may be woven into the pad as further explained in connection with FIGURE 4, or any other suitable means of engaging the strips with the terminal pads may be employed. The two

strips

12, 14 are sandwiched between the two groups of pads. A common cover 16, preferably of a material such as cheesecloth, is wrapped around the plurality of pads and the strips to form a unitary structure 10, however, end portions of the strips i2, 14 are arranged to extend outwardly of the cover 16 to provide a means 4for removing the napkin 10 after use.

The napkin l()i may be removed from a holder, or region of use by grasping together the flexible strips 12,

14 at their foremost ends and imparting a pull thereto..

To dispose of the napkin lil the strips 12., 14 are pulled in opposite directions which will cause the outer cover i6 to unwrap and cause the napkin 101 to fall apart. It is readily seen that the pads, 1, 2, 3, 4, 5 are of a Size which may be easily accommodated by the usual home water closet and thus ilushed without danger of stoppage presently experienced from napkins commonly sold.

It is noted that it is preferable to arrange as many small pads within a given size napkin as is practicable. A plurality of small pads will present a greater absorption surface to the wearers body than a single pad of equal total area, because of the additional surface provided at the points Where the pads touch one another. The greater the number of pads in the group adjacent to the wearers ybody, the more ilexible is the napkin. This permits contour tting to the Wearers body, providing more comfort and greater eiciency. The tighter lit resulting attenuates iluid odors and assures total abs0rp tion of fluids by the napkin 10. It is usual to provide a different num er of pads in the group adjacent the wearers body than in the group away from the wearers body to insure that any crevices formed between adjacent pads do not extend the depth of the napkin 10, but other means for preventing this may be employed.

Also, since for a given size napkin, the size of the pads is inversely proportional to their number, a napkin employing a larger number of pads may be more easily disposed of.

FIGURE 3 illustrates an alternate embodiment of the present invention providing a more positive separation of the napkin 2) into its component segments. Again, a plurality of small absorbent pads are arranged in two groups. A first group consists of three pads, 28, 30, 32, while the second group has two

pads

34, 36. In this embodiment, the rst strip 22 is interwoven amon tire pads of the first group, engaging at its terminal end a surface of the furthermost pad of that group, 32. The second strip 24 similarly interweaves between the pads of the seco-nd group, being engaged at one end to a surface of the furthermost pad 34. As an optional feature a fluidrepellant member 3S may be arranged below the plurality of pads furthest away from the body of the wearer,

preventing standing of clothing should body fluids soak' through the pads to the bottom of the napkin l0. A common cover 26, preferably of gauze-like material, encompasses the pads, 28, 36, 32, 34, 36, the fluid-repellant member 38, and the

strips

22, 24, save for the foremost portions of the strips 22, 2d which extend beyond the wrapping cover 26. Alternatively, that portion of the cover 26 at the bottom of the napkin l0 may be made fluid-repellant, thus obviating the need for the fluid-repellant member 38. As in the previous embodiment, -th'e napkin 20' may be removed from use by application of a grasping and pulling motion to the strips 22, 2d. To disintegrate the napkin 2t? into its component parts for easy Water closet disposal, the strips may be pulled in opposite directions. It is seen that a positive unwrapping action of the cover 26 will result, freeing the pads for flushing.

Turning now to FIGURE 4 there is shown a fragmentary sectional view of a modification of the sanitary napkin of FIG. 3. As in the previous figures, a plurality of pads including the two shown 32', 34 are arranged within a wrapping 26. The first of the separating strips 22 isshown to be woven within the material of one of the absorbent pads 32 in the first group. The second of the strips 24 is shown woven within the fabric of one of the absorbent pads 3d' in the second group. The sanitary napkin Ztl is otherwise similar to the structures disclosed in the previous figures.

FIGURE 5 shows yet another embodiment of a sanitary napkin 40 of simplified construction according to the present invention. A single plurality of pads, shown here as a first pad 47, second pad 48, and third pad 49' are arranged with a wrapping 45 which is folded to enclose said pads. Means for separating the napkin lo into its component parts for easy disposal after use are provided in the for-m of a pair of

flexible strips

42, 44, which interweave among the pads. Beginning at the exterior of the wrapping 46., the

strips

42, 44, run along the bottom surface of the first pad 47, up the interstice between said first pad 47 and second pad 48, along the top of the second pad 48, down the interstice between the second pad 4S and the third pad 49, and along the bottom of the third pad 49 to the exterior of the wrapping 46. The

strips

42, 44 may be grasped at either end to remove the napkin 46 from the position of use and it may be separated into its smaller portions for easy water closet disposal by pulling the

strips

42, 44 in opposite directions.

As an optional feature, deodorant material may be introduced within any of the napkins described herein. The segmenting of the pads within the napkin suggests the introduction of a deodorant material in one or more of the intersti'ces between adjacent pads. rlhe deodorant material may be sandwiched between the pads in the manner of the

strips

12, 14 of FIG. 2, or arranged within the napkin as the fluid-repellant member 38 of FIG. 3. Provision of deodorant material together with the tight fit provided by lthe flexible construction of the napkin affords a high degree of odor attenuation.

What has been described is an improved sanitary napkin of novel construction permitting clean, efficient disposal through an ordinary water closet. The napkin described possesses .superior absorbent qualities and thus attenuates fluid odors `to a higher degree. It is to be understood that the forms of the invention herewith shown and described are to be taken as preferred examples of the same and that various changes in the shape, size and arrangement of the parts may be resorted to without departing from the spirit of the invention and scope of the subjoined claims. For example, the number and size of the component pads may vary. The flexible strips may be fabricated in part of fiuid-proof material, particularly at their foremost end. Any suitable soft absorbent material may be used in the pads.
