Abstract

Waste fluid absorption devices, including sanitary napkins, tampons and baby diapers, comprising coplanar multiple ply of thin absorbent tissue paper, are impregnated in selected exterior border areas with non-toxic, waste fluid repellant compositions. The repellant compositions are applied in the minimum concentrations necessary, and produce separate and discrete tissue paper plies which are not easily wet by menstrual and urine fluids. Sanitary napkins comprising coplanar multiple ply of tissue paper disposed in an elongated pattern are impregnated at the exterior border planar area of the napkin, typically for a border area of 1/8 - 1/4 inch width disposed around the menstrual fluid absorptive section. A menstrual tampon comprises coplanar multiple plies of absorbent tissue paper formed into a compressed cylindrical tampon. The tampon end opposite the insertion end of the tampon is impregnated with a menstrual fluid repellant composition, in a concentration sufficient to prevent menstrual fluid flow through the interstices of paper plies of the tampon. The baby diaper is impregnated along the absorbent pad diaper edges.

The repellant compositions are applied in the minimum concentrations necessary, and produce separate and discrete tissue paper plies which are not easily wet by menstrual and urine fluids. Sanitary napkins comprising coplanar multiple ply of tissue paper disposed in an elongated pattern are impregnated at the exterior border planar area of the napkin, typically for a border area of /4 inch width disposed around the menstrual fluid absorptive section. A menstrual tampon comprises coplanar multiple plies of absorbent tissue paper formed into a compressed cylindrical tampon. The tampon end opposite the insertion end of the tampon is impregnated with a menstrual fluid repellant composition, in a concentration sufficient to prevent menstrual fluid flow through the interstices of paper plies of the tampon. The baby diaper is impregnated along the absorbent pad diaper edges.

13 Claims, 7 Drawing Figures 1 WASTE FLUID FLOW CONTROL ELEMENT CROSS-REFERENCE TO RELATED APPLICATIONS This application relates to the copending application U.S. Ser. No. 720,500, filed Apr. 11, 1968, now U.S. Pat. No. 3,532,097 and to the copending application Ser. No. 742,922, filed July 5, 1968, now U.S. Pat. No. 3,593,717 all relating to improvements in sanitary napkins taught by this inventor. This application relates to the copending application on the improvements in menstrual tampons, Ser. No. 720,501, now U.S. Pat. No. 3,610,243 filed Apr. 11, l968 by this inventor. This application also relates to the U.S. application of this date titled OPTIMUM PROFILE DIAPER PAD.

BACKGROUND OF THE INVENTION Commercially available sanitary napkins comprise menstrual fluid absorptive sections of fluffed, bleached wood pulp. The face of the sanitary napkin wood pulp pad disposed distant from the body surface in use is typically covered with a very thin polyethylene film. Likewise separate thin polyethylene films cover the two long sides of the sanitary napkin pad, as it is normally disposed on the female torso. These thin films of polyethylene, or the like plastic, control the flow of menstrual fluid, preventing the fluid from exuding from the absorptive wood pulp section and soiling the wearers clothes and the like. The fluffed and spongy dry wood pulp behaves in some mechanical aspects as a typical sponge, absorbing menstrual fluid and then releasing the fluid when the wood pulp absorptive section is compressed, as by body movement. In contrast, the multiple plies of absorptive tissue paper, having considerably smaller cellular dimensions with respect to air space, do not behave as a typical sponge, for they retain the menstrual fluid on absorption. In the menstrual sanitary napkins of the inventions listed above, the exterior border planar volumes of the coplanar multiple plies of tissue paper can be formed into menstrual fluid repellant volumes without destroying the softness, flexibility and feel-to-the-skin of the tissue paper stock contained in the napkins.

The commercially available menstrual tampons comprising cotton and rayon fibers are effective absorbers of menstrual fluid. However, also acting mechanically as sponges, they can release menstrual fluid on body movement. It is desirable to provide a menstrual fluid flow control element for the tampon positioned in use, which would prevent leakage of the menstrual fluid from the tampon end nearest the vaginal opening. It is well known that babies excrete urine while lying in a variety of positions in a crib. Disposable, single use diapers can have fluffed bleached wood pulp and tissue sheet stock waste absorbent pad combinations. It is very desirable to provide a waste fluid flow control element along the exterior edges of the waste absorbent pad, to control the direction of flow of urine and the like. As disposable diapers are now manufactured, it is very useful to provide a waste fluid control element along the two waist band edges of the diaper, as made in the cross-reference patent application.

SUMMARY OF THE INVENTION Menstrual fluid flow control elements are taught for the sanitary napkins and the tampons having multiple plies of fluid absorbent tissue paper. The normal tissue paper stock has a microscopic cellular structure much smaller than that of conventional fluffed, dry bleached wood pulp used in commercial sanitary napkins, and that of cotton and rayon fiber structures used in conventional menstrual tampons. The exterior border planar area of elongated menstrual sanitary napkins having coplanar multiple plies of absorptive tissue paper, as cross referenced above, have menstrual fluid flow control elements. Likewise, the menstrual tampons, as cross referenced above, comprising coplanar multiple plies of absorptive tissue paper, has the tampon end opposite the insertion end formed into a menstrual fluid flow control element. The disposable baby diaper pad has tissue paper sheet above or in combination with fluffed wood pulp, to form a waste absorbent pad. The pad can have a fluid flow control element disposed along the edges devised to encircle the babys abdomen, as well as along the longitudinal diaper edges which encircle the baby s thighs.

The waste fluid flow control element is formed by treating the required geometrical volume portion of the napkin and tampon with a non-toxic menstrual fluid repellant composition which does not substantially modify the texture or the feel-to-the-skin of the separate plies of tissue paper stock. Typically the repellant impregnant can be non-volatile dimethyl polysiloxane fluids; non-volatile polyfluorocarbon fluids; nonvolatile hydrocarbon oil fluids; non-volatile fluid long chain fatty acid alkyl esters, and non-volatile mono, di and triglyceride esters of long chain fatty acids; the zinc, calcium, magnesium and aluminum salts of long chain fatty acids; and the mixed compositions of said esters of long chain fatty acids and glycerides and said salts of said fatty acids. The non-toxic fluid repellant impregnant can be applied to the required napkin, tampon and diaper volume by a printing process such as gravure or the like, or by spraying, or by roll coating.

Included in the objects of this invention are:

First, to provide waste fluid flow control elements for multiple ply, absorptive tissue paper sections of sanitary napkins, tampons and diapers.

Second, to provide a simple process for manufacturing waste fluid flow control elements in sanitary napkins, tampons and diapers having coplanar multiple ply, tissue paper menstrual fluid absorptive sections.

Third, to provide waste fluid repellant elements for sanitary napkins, tampons, and diapers, having coplanar, multiple ply absorptive tissue paper sections.

Fourth, to provide waste fluid repellant compositions for the required exterior border areas of sanitary napkins, tampons and diapers.

Further objects and advantages of this invention will become apparent in the following description, to be read in conjunction with the accompanying drawing.

BRIEF DESCRIPTION OF THE DRAWING FIG. 1 is a plan view of a sanitary napkin embodying the menstrual fluid flow control element of this invention.

FIG. 2 is a cross sectional view through 2-2 of FIG. 1, further illustrating the geometrical position of one menstrual fluid flow control element of this invention. FIG. 3 is a plan view of another embodiment of the menstrual fluid flow control element, illustrating in detail the configuration of the fluid control element at the obtuse end of a sanitary napkin.

FIG. 4 is a further cross sectional view of another modification of the fluid flow control element of this invention.

FIG. 5 is an elevational perspective view of a printing means which may be used in applying the'manufacturing process of this invention.

FIG. 6 is a cross sectional view through a tampon disposed in an applicator tube, as taught in applicants invention disclosed earlier in U.S. Ser. No. 720,901, illustrating the geometrical position of the fluid flow control element in a tampon.

FIG. 7 is a plan view of a diaper illustrating the geometrical disposition of waste fluidflow control element in the absorbent pad of the diaper.

DESCRIPTION OF THE PREFERRED EMBODIMENT napkin l. The multiple menstrual fluid reservoirs 5 are symmetrically disposed about the center line 16 and the section line 2-2, as taught in the above application. In the planar view of FIG. 1, the menstrual fluid flow control element 6 is shown disposed inside and adjacent the exterior edge 7 of the napkin 1, and 6 is also continued around and adjacent to the pair of slot openings 4. The dotted line 8 denotes the interior edge of the menstrual fluid flow control element6, and the opposed pair of dotted lines 9 denote the exterior edge of the menstrual fluid flow control element 6 disposed in the interior of the napkin adjacent the pair of slotted securing openings 4. The planar border area 10 of the menstrual fluid flow control element 6 has a thickness depth 11 further illustrated in cross sectional view in FIG. 2. Thus collectively the border volume enclosed by the planar border area 10 and the thickness depth 11 form the volume of the menstrual fluid flow control element 6. The interface bond means 12, shown in FIG. 2, secures the thin impermeable plastic film l3, both of which are taught in the above listed patent applications.

. As is illustrated in FIG. 1, both opposed napkin tips 14 are excluded from the menstrual fluid absorptive section 15, which lies inside the interior edge 8 of the menstrual fluid flow control element 6.

In a further embodiment of the menstrual fluid flow control element, FIG. 3 illustrates the menstrual fluid flow control element G'hxtending around the complete exterior edge 7 of the sanitary napkin 1. Thus the menstrual fluid absorptive section 15 is formed from all of the coplanar multiple ply tissue paper 2 which lie inside of the menstrual fluid flow control element 6'. The exterior planar border area 10' of the flow control element 6 extends completely around and inside of the exterior edge 7 of the sanitary napkin 1'. The adhesive plug bonding means 3' and the napkin securing slot openings 4' are disposed inside the interior edge 8' of the flow control element 6.

Referring to the cross sectional view of FIG. 4 in detail, the coplanar multiple ply tissue paper 2" is shown to have a menstrual fluid flow control element 6". The fluid flow control element 6" is formed in the volume contained by the exterior planar border area 10' integrated over the thickness depth 11''. The major thickness depth 1 l is shown to extend from the exterior absorptive surface 18 of the napkin, partially through the complete thickness 17 of the coplanar multiple ply tissue paper 2". As in the napkin 1 shown in cross sectional detail in FIG. 2, the cross sectional illustration of FIG. 4 shows the interface bonding means 12" securing the thin impermeable plastic film 13". In functional use the exterior absorptive face 18 of the type of a napkin l, or the like, is the face through which menstrual fluids are typically initially absorbed. Since the menstrual fluid flow control element 6" extends from the absorptive face 18 of the napkin through a major proportion 11" of the thickness 17 of the coplanar multiple ply tissue paper 2", the fluid flow control element 6" will direct the flow of menstrual fluid interiorly into the menstrual fluid absorptive section 15", or the like, of the typical sanitary napkin l" or the like. Therefore, the spread of absorbed menstrual fluid will be directed primarily into the interior of section 15" by the capillary processes which control flow of fluids in porous paper stock, and will be restrained from moving toward the exterior edge 7", or the like, of the sanitary napkin, even though the fluid flow control element 6" extends only over a major proportion 11" of the thickness 17 of the sanitary napkin.

Referring to FIG. 5 in detail, the coplanar multiple ply tissue paper tampon 50 is shown disposed in a standard paper exterior applicator tube 51. The withdrawal string 52 is shown looped around the U-end of the tampon 50 forming the two legs 53 and 54 of the paper tampon 50. The tampon end 55 is designated the insertion end, as it is normally first inserted into the vaginal opening. The tampon end 56 is designated the tampon end opposite the insertion end 55. A menstrual fluid flow control element 57 is formed in the exterior volume of the tampon end 56 by impregnating the surface portion of the tampon end 56 with the non-toxic water repellant impregnant, in full equivalence to the menstrual fluid flow control impregnants discussed above. The water repellant impregnant may be applied to the tampon, after the tampon is disposed in the applicator tube as by spraying, or roll coating, or adding a drop of impregnant to the tampon end 56, or the like. Typically 0.05 to 0.15 g. of impregnant is useful.

It is obvious that when the tampon 50 is inserted into the vaginal opening in the normal functional position, the menstrual fluid flow control element 57 will prevent leakage of menstrual fluid from the tampon as it will tend to prevent menstrual fluid being squeezed from the tampon 50 through the element 57, as by body motion.

Referring to FIG. 7 in detail, the disposable diaper 70 has a waste absorbent pad 71 cooperatively symmetrically disposed on a waste fluid impermeable plastic membrane 72. The pair of longitudinal membrane border seals 73 and 74 are formed by folding over the wider membrane width on to the absorbent pad 71 and forming the seals 73 and 74, securing the pad 71 in position. The infant waist encircling diaper ends 75 and 76 have waste fluid flow control elements 77 and 78 disposed in the waist band sections 79 and 80, as earlier taught above for sanitary napkins and tampons. When the improved infant diaper is suitably cooperatively secured on an infant with the waist band sections 79 and 80 encircling the infant, the waist fluid flow control elements 77 and 78 will greatly impede the flow of urine around the infants waist while the infant is lying down in the crib or being held in someones arms. The waste fluid flow control elements can also be disposed in the absorbent pad 71, as a pair of elements 81 and 82, closely adjacent and parallel to the longitudinal membrane border seals 73 and 74, providing additional protection to urine and feces flow around the infants legs.

In its general embodiment, the waste fluid flow control element 6, or the like, comprises two components. The first component is a suitable disposed volume of coplanar multiple ply of tissue paper of an absorptive non-calendared tissue paper stock of a suitable width and depth to form an exterior edge volume, and the second component is a waste fluid repellant composition reasonably uniformly disposed in the designated first component absorptive section volume. Briefly the waste fluid flow control element comprises the border planar volume of the multiple ply of tissue paper absorptive section and a nontoxic menstrual fluid repellant impregnant disposed in the exterior planar border volume of the absorptive pad. Specifically, the nontoxic waste fluid repellant impregnant is of a character which wets and impregnates the porous uncalendared tissue paper stock in the separate, individual, discrete paper plies, without bonding the plies together in a laminated type of mechanical structure. The impregnant is specifically provided to prevent the waste fluid from wetting and going through the waste fluid flow control element. At the same time it is provided that the waste fluid repellant impregnant will not destroy the softness, flexibility and softness of touch to the skin necessary to prevent chafing of the body skin in contact during movement.

Non-toxic waste fluid repellant impregnants which are suitably useful are as follows:

' l. nonvolatile dimethyl polysiloxane fluids, manufactured for waterproofing paper stock.

2. nonvolatile polyfluorocarbon fluids, manufactured for waterproofing paper stock.

3. zinc, calcium, magnesium and aluminum stearates dissolved in liquid hydrophobic, non-volatile bases, such as butyl stearate, refined bleached mineral (USP. XV-l955), refined corn oil and other refined edible oils and modified mono and diglycerides, alkyl stearates and the like esters of long chain fatty acids. The above listed types of non-toxic, non-volatile, liquid hydrophobic oil bases are substantially improved by the addition of the listed metal stearates, in typical concentration ranges of -90 wt percent. The solutions can be used hot, to provide the desired metal stearate concentration. Other non-toxic metal salts of other long chain fatty acids may be used, but water soluble foam ing soaps should be avoided.

Other suitable menstrual fluid repellant compositions may be used as impregnants. characteristically the menstrual fluid repellant composition should be non-toxic and water repellant or hydrophobic. The menstrual fluid repellant should be either a liquid at room temperature, or be a high melting lubricant solid such as zinc or magnesium, or the like stearate, which will not fuse on standing in commercial storage to form a waxlike, fused solid. The repellant should not bond the multiple plies of tissue paper together into a laminated mass.

The fluid repellant composition can be applied to form the menstrual fluid flow control element by spraying, roll coating or by a printing processon a napkin 1 or the like. FIG. 6-illustrates a perspective elevation view of a printing frame shaped to provide the configuration of the menstrual fluid flow control element 6 of the sanitary napkin 1. As is well known, the printing face 61 of the printing frame may have a surface gravure configuration adapted to provide the required amount of a menstrual fluid repellant composition on the printing face to be applied to a specific sanitary napkin or its separate plies. Thus in principle the sanitary napkin l, or the like, may be cut into shape from a raw stock of coplanar multiple plies of tissue paper, and simultaneously may be printed within the exterior edge of the newly cut sanitary napkin to provide the menstrual fluid flow control element 6, or the like. By controlling the gravure configuration on the printing face 61 of the printing frame 60, and by simultaneously controlling the viscosity of the menstrual fluid repellant composition being applied to the printing face 61, it is possible to vary the quantity of repellant composition to provide the required structure of the menstrual fluid flow control element 6.

By selecting and controlling the application method or process; the viscosity of the repellant fluid composition or the particle size of the applied zinc stearate, or the like metal soap; and the amount of repellant composition applied; it is possible to control the width of the exterior planar border area 10 and the depth or thickness 11, of the menstrual fluid flow control element 6, or the likes, in other napkins. Typically the width of border area 10 can range from one-eighth to one-fourth inch. The depth or thickness 11 of the element 6 can range typically from all tissue plies to twothirds of the plies, or the like.

The weight of the menstrual fluid repellant composition which is applied is that amount required to produce the desired volume of the menstrual fluid control element. Typically, a 50 wt percent of zinc stearate (USP) dissolved in hot butyl stearate solvent (cosmetic grade) was sprayed, while hot, on stacked napkins. The napkins were vertically stacked with the absorptive section 15 of one napkin 1 adjacent to the plastic film 13 of another napkin 1, the napkins 1 being coaxially aligned on the center lines 2-2 and 16. The weight of the above impregnant composition applied to each napkin l, forming an element 6', or the like, was about 0.5 g. On testing the border menstrual fluid control element with a colored aqueous dye solution, the control element 6', or the like, was clearly dye impervious for the full thickness of the depth 11, or the like, and the width of border area was approximately 3/16 to 34; inch. Fused zinc stearate, magnesium stearate, or other low melting water insoluble, non-toxic metal fatty acid salts can be sprayed or roll coated as the impregnant in the element 6', or the like.

The 25 wt percent solution of zinc stearate in butyl stearate is desirable due to low cost, fluid impermeability, and nontoxic nature. Other water repellant fluid impregnants, vsuch as the waterproofing dimethyl polysiloxanes and polyfluorocarbons may be applied, at typical concentration as required on the weight of a napkin. Zinc stearate alone may also be impregnated in the edge of a napkin to form a useful flow control impregnant. The chromium (Cr complex of N-ethyl- N-heptadecylfluoro-octane sulfonyl glycine aqueous solution (0.7 wt percent), also containing 2. wt percent urea, was sprayed on the edges of vertically stacked napkins, as described above. The weight of impregnant of the above chromium complex after drying was 0.0035 gram on the total napkin weight of 8.0 g, disposed in a 3/ l 6% inch wide control element 6', or the like. The test of the napkins with the similar aqueous dye solution, as above, indicated the chromiumfluorocarbon complex was a very effective moisture repellant in the border menstrual fluid control element 6', or the like. The complex compound is approved by the Food and Drug Administration for contact with food, in food package (Federal Register, Title 21, Part 121.2518-Aug. 7,1961) A wt percent of zinc stearate in butyl stearate is particularly desirable for a pair of waste fluid flow control elements 77 and 78, or the like, applied as inch wide control elements to a continuous web of disposable diapers during the manufacturing process.

The above chromium (Cr complex of the fluoroglycine derivative can also be used in the stated formulation to impregnate 2-4 plies, or the like, of 9-1 1 lb. absorbent tissue paper sheet stock. The dried, impregnated tissue stock can then be used as the equivalent of the thin impermeable plastic film 13 of FIG. 2. Typically, a four-ply tissue sheet impermeable film equivalent to 13 may have 0.0025 g of waterproofing fluoroglycine derivative per napkin. The completed napkin, having the impregnated water resistant tissue ply without an impermeable plastic film 13, is now quite resistant to aqueous dye fluids penetrating the exterior water resistant tissue ply, in comparison with a similar napkin having no water resistant tissue ply. The impregnated water resistant tissue sheets disposed on the napkin exterior have the distinct advantage of still being porous, as measured by blowing smoke through the water resistant tissue. Due to thesmall air cell size ,of the water resistant tissue paper sheet, as compared Obviously many modifications and variations in the waste fluid flow control element can be made in the light of this teaching. Itis therefore understood that within the scope of the appended claims, the invention may be practiced otherwise than as specifically described.
