Description

COMPOSITE SANITARY TOWEL THAT ADJUSTS THE BODY FIELD OF THE INVENTION The present invention relates to disposable sanitary napkins. More particularly, the invention relates to a sanitary composite pad comprising a primary absorbent member and a base member, wherein the primary absorbent member comprises a primary absorbent member.

BACKGROUND In its simplest form, disposable sanitary napkins comprise an absorbent element (sometimes referred to as an absorbent core) interposed between a liquid permeable sheet facing the body (sometimes referred to as a top sheet) and a sheet liquid impervious to the undergarment (sometimes referred to as a backsheet). Of course, the absorbent element aims to receive and contain menstrual bleeding and other vaginal discharges. The face-to-body sheet is intended to provide more or less comfort and dry feel on contact with the surfaces of the body as long as the free passage of fluids through it is allowed to the absorbent element. The sheet 3 facing the undergarment intended to prevent menstrual bleeding or other vaginal discharges that are expelled or escaping the absorbent element soiling the undergarments of the wearer. In addition to the three functional elements mentioned above, disposable sanitary napkins are generally provided with means for supporting the device adjacent to the user's crotch area, even while the user is moving, where he can perform the proposed function in the most effective manner. Typically, sanitary napkins are provided with adhesive fastening means to secure the device to the inner crotch area of the wearer's underwear. While the previously known sanitary napkins perform their proposed functions, each particular design suffers from certain deficiencies in one or more absorbency of body fluids, protection against soiling of the wearer's undergarments, and / or physical comfort to the wearer . With respect to disposable sanitary napkins, at least two general classes are present. One such class is identified as being proposed for the absorption of menstrual flows from medium to high. These sanitary napkins offer a relatively high absorbent capacity. Absorbent capacity is commonly achieved by providing the sanitary napkin with a relatively thick and bulky absorbent member. While it has a relatively high absorbent capacity, the volume of the absorbent body can cause a certain degree of • discomfort to dress. A second class of sanitary napkins is proposed for mild or low menstrual flows and is commonly referred to as pantyhose or panty liners. Sanitary pads of this kind, as a group, are thinner, for some reason more flexible and generally more comfortable than those of the first class. However, second-class sanitary napkins typically lack the absorbent capacity of first-class sanitary napkins. An attempt to provide the benefits of the two previously described kinds of sanitary napkins in a single sanitary napkin is disclosed in commonly assigned U.S. Patent No. 4,425,130 issued to DesMarais on January 10, 1984. The sanitary napkin composed of DesMarais comprises a primary menstrual pad and a panty protector attached to each other at their corresponding ends such that the two constituents are free to move relative to one another essentially along their entire common length. In use, the relative freedom of movement between the primary menstrual pad and the pant liner serves to maintain the primary menstrual pad adjacent to the wearer's crotch region while the pant liner remains associated with the wearer's underwear. While the relative freedom of movement between the primary menstrual pad and the pant liner serves to maintain the primary menstrual pad close to the crotch region of the wearer, this freedom of movement can lead to a lack of stability if the primary menstrual pad moves laterally beyond the side edges of the panty liner, providing an opportunity for soiling the wearer's underwear. While absorbent articles of the state of the art such as sanitary napkins have addressed some of the problems of achieving a sanitary napkin, they have not addressed the problems to the limit or in the manner of the present invention. Therefore, a main object of the present invention is to provide an improved composite sanitary napkin.

BRIEF DESCRIPTION OF THE INVENTION The present invention relates to a sanitary composite pad that fits the body having a primary absorbent member and a secondary absorbent member. The primary absorbent member has a longitudinal length, a transverse width, a thickness, a pair of longitudinal sides and a pair of transverse ends, and comprises a primary absorbent member and a fluid permeable cover superimposed on the primary absorbent member. The secondary absorbent member has a longitudinal length, a transverse width, a thickness, a pair of longitudinal sides and a pair of transverse ends, and comprises a fluid-permeable body facing sheet, a waterproof clothing facing sheet fluid attached to the sheet facing the fluid permeable body; and a secondary absorbent element positioned between the sheet facing the fluid permeable body and the fluid facing sheet facing the garment. The primary absorbent member is fixed to the side of the sheet facing the fluid-permeable body of the secondary absorbent member by attachment means. A ratio of the thickness of the primary absorbent member to the transverse width of the primary absorbent member is between 0.05 and 1.5. The primary absorbent member has an absorption capacity of at least 70% of the menstrual fluid charged between 2 and 30 grams when the sanitary napkin is applied to the female body and used. The present invention also relates to a sanitary composite pad that fits the body comprising a primary absorbent member and a secondary absorbent member. The primary absorbent member has a longitudinal length, a transverse width, a thickness, a pair of longitudinal sides and a pair of transverse ends, and comprises a primary absorbent member and a fluid permeable cover superimposed on the primary absorbent member. The primary absorbent comprises hydrogel forming polymers and hydrophilic fibers. The secondary absorbent member has a longitudinal length, a transverse width, a thickness, a pair of longitudinal sides and a pair of transverse ends, and comprises a fluid-permeable body facing sheet, a waterproof clothing facing sheet fluid attached to the sheet facing the fluid permeable body; and a secondary absorbent element positioned between the sheet facing the fluid permeable body and the fluid facing sheet facing the garment. The primary absorbent member is fixed to the side of the sheet facing the fluid-permeable body of the secondary absorbent member by attachment means. A ratio of the thickness of the primary absorbent member to the transverse width of the primary absorbent member is between 0.05 and 1.5. The primary absorbent member includes the hydrogel forming polymers of between 0% and 60%.

DETAILED DESCRIPTION OF THE INVENTION The present invention is a sanitary composite pad that adjusts to the body which exhibits absorbency for bodily fluids, protection of garments from -the user's inner clothing against staining, and physical comfort to the user. The term "sanitary napkin", as used herein, refers to an article that is worn by women adjacent to the pudendal region and which is intended to absorb and contain various exudates that are discharged from the body (eg, blood, menstrual bleeding and urine) and which is proposed to be discarded after a single use (for example it is not intended to be washed or otherwise restored or reused). The term "Composite sanitary napkin", as used herein, refers to a sanitary napkin comprising separate constituents attached to one another to form a unitary structure. The interlabial devices which reside partially within and partially external to the user's vestibule are also within the subject matter of this invention. As used herein, the term "pudendal" refers to externally visible female genitalia and is limited to the labia major, the labia minora, the clitoris, and the vestibule. Referring now to Figures 1-3, there is shown a preferred embodiment of a composite sanitary napkin 20. The sanitary napkin 20 has two surfaces, a front surface 20A or which makes contact with the body and a front surface or that makes contact with the undergarment 20B. The composite sanitary napkin has a first end region 27, a central region 28, a second end region 29, longitudinal sides 16 and transverse ends 18. The sanitary napkin 20 has two centerlines, a longitudinal centerline L and a transverse center line T. The term "longitudinal", as used herein, refers to a line, axis or direction in the plane of the sanitary napkin that is generally aligned with (eg, approximately parallel to) a vertical plane which bisects a user standing on the left and right body halves when dressing the compound sanitary napkin. The terms "transverse" or "lateral", as used herein, are interchangeable, and refer to a line, axis or direction which rests within the plane of the sanitary napkin which is generally perpendicular to the longitudinal direction. As can be seen in Figures 1-3, the sanitary composite pad 20 comprises a primary absorbent member 30 and a secondary absorbent member (base member) 50 held together by attachment means 70. Each of the primary and secondary absorbent members they have corresponding surfaces facing the body and facing the underwear article. The primary absorbent member 30 has longitudinal sides 24 and transverse ends 25 which together form the periphery 26 of the primary absorbent member 30. The primary absorbent member 30 also has a longitudinal extension PL and a transverse width PW, and a thickness PT. The secondary absorbent member 50 has longitudinal sides 21 and transverse ends 22 which together form the periphery 23 of the secondary absorbent member 50 and the sanitary composite pad 20. The secondary absorbent member 50 has a longitudinal extension SL and a transverse width SW and a thickness ST . As shown in figure 1, preferably, the sanitary napkin 20 has fins 33 extending from the longitudinal sides 21 of the secondary absorbent member 50 in the central region 28 of the sanitary napkin 20. The primary absorbent member 30 is, as the name implies, the constituent of the composite sanitary napkin 20 which is proposed to absorb the volume of the fluids discharged by the user. The primary absorbent member 30 generally has a rectangular shape extending in the longitudinal direction along the longitudinal center line L. In a preferred embodiment the longitudinal extension PL can generally be equal to the longitudinal extension SL of the secondary absorbent member 50. The transverse width PW can generally be narrower than the transverse width SW of the secondary absorbent member 50. The primary absorbent member 30 comprises a primary absorbent member of such form that an absorbent core 34, a liquid permeable cover such as a fluid-permeable upper sheet. 32 superimposed on the core 34. The upper sheet 32 is preferably docile, sensing, and non-irritating to the wearer's skin. Additionally, the top sheet is permeable to the fluid, allowing the fluid to easily penetrate through its thickness. A convenient top sheet 32 can be made from a wide range of materials such as woven or non-woven materials; polymeric materials such as openings formed of thermoplastic films, open plastic films and hydroformed plastic films; and thermoplastic canvases. The woven or non-woven materials may be formed of natural fibers (for example wood or cotton fibers), synthetic fibers (for example, polymer fibers such as polyester, polypropylene, or polyethylene fibers) or a combination of synthetic fibers and fibers. natural A preferred top sheet comprises a film formed with openings. Films formed with openings are preferred for the upper sheets because they are permeable to body exudates and not yet absorbent and have a reduced tendency to allow fluids to pass back through and rewet the user's skin. Therefore, the surface of the formed film that is in contact with the body remains dry, whereby the staining of the body is reduced and a more comfortable feeling is created for the user. Suitable shaped films are described in U.S. Patent No. 3,929,135 issued to Thompson, December 30, 1975; U.S. Patent No. 4,324,246 issued to Mullane et al. On April 13, 1982; the Patent of the States United 4,342,314 issued to Radel and others on August 3, 1982, Patent of the 'United States No. 4,463,045, issued to Ahr et al. On July 31, 1984 and the Patent -of United States No. 5,006,394 issued to Baird on April 9, 1991. Each of these patents are incorporated herein by reference. The preferred top sheet for the primary absorbent member of the present invention is a formed film described in one or more of the above patents and marked on sanitary napkins by Procter & • Gamble Company of Cincinnati, Ohio as "DRY-WEAVE". The exposed surface or body of the formed film top sheet can be hydrophilic to help the fluid transfer through the top sheet be faster than if the body surface were not hydrophilic to decrease the likelihood that the menstrual flow flows out of the upper sheet instead of flowing in and being absorbed by the absorbent core. In a preferred embodiment, surfactants may be added within the polymeric materials of the formed film topsheet as described in PCT publication no. WO93 / 09741 published May 23, 1993 in the name of Aziz et al., Which is incorporated herein by reference. Alternatively, the body surface of the topsheet can be rendered hydrophilic by treating it with a surfactant such as described in U.S. Patent No. 4,950,264 issued to Osborn, August 21, 1990 and which is herein incorporated by reference. In a preferred embodiment of the present invention, as shown in Figure 4, the sheet 32 may comprise a non-woven material 37 and a formed film 36 superimposed on the non-woven material 37. The formed film 36 has a first surface 38 facing the outside, a second surface 39 facing the non-woven material 37 and the absorbent core 34, and openings 42 extending from the first surface 38 to the second surface 39. The area of the openings 42 in the second surface 39 adjacent the absorbent core 34 generally the area of the openings 42 in the first surface 38. Because the opening area of the first surface 38 Generally, it is greater than the area of the opening of the second surface 39, the fluid can easily penetrate the upper sheet 32 towards the absorbent core 34. However, this inhibits r the fluid acquired in the absorbent core 34 from being transferred from the core. absorbent 34 to the outside and rewet the user's skin. The nonwoven material 37 is superimposed on the second surface 39 of the formed film. Each one of the film formed 36 and nonwoven material 37 has a rectangular shape when the film formed 36 and the nonwoven material 37 are unfolded as shown in Figure 5.

The topsheet 32 has longitudinal sides and transverse ends 46. The formed film 36 has longitudinal sides 43 and transverse ends 44 respectively, and the : non-woven material 37 has longitudinal sides 47 and corresponding transverse ends 48. The formed film 36 and the nonwoven material 37 may be superimposed by any convenient manner. Preferably, the formed film 36 and the non-woven material 37 may be adjacent to each other along the longitudinal sides 45 by a plurality of discrete points 49. The discrete dots may be formed by applying pressure, heat, pressure and heat, and / or adhesive. Alternatively, the formed film 36 and the nonwoven material 37 can be bonded to one another along the entire length of the longitudinal sides 45. The absorbent core 34 can be any absorbent means that is generally compressible, comfortable, Resilient, non-irritating, to the user's skin and capable of absorbing and containing body exudates. The absorbent core 34 can be manufactured from a wide variety of fluid absorbent materials commonly used in disposable sanitary napkins, and other disposable absorbent articles. Examples of suitable absorbent materials include powdered wood pulp (referred to as an air filter) cellulose casing. accreted, modified cross-linked cellulose fibers (such as those described in : United States Patent No. 5,217,445 issued to Young and others on June 8, 1993) fibers of capillary channels (ie, fibers having capillary channels between fibers such as those described in U.S. Patent No. 5,200,248 issued to Thompson et al. On April 6, 1993), absorbent foams (such as those described in U.S. Patent No. 5,260,345 issued to DesMarais et al. On November 9, 1993 and U.S. Patent No. 5,268,244 issued to DesMarais and others on December 7, 1993), materials deposited by thermally bonded air (such as those materials described in the US Pat. No. 5,607,414 issued to Richards et al. On March 4, 19997), hydrogel polymeric forming agents (such as those described in U.S. Patent No. 4,673,402 issued to Weisman et al. On June 16, 1987 and U.S. Patent No. 4,935,002 issued to Lash et al. on June 19, 1990), absorbent sponges, synthetic raw material fibers, polymeric fibers, swamp moss, or any equivalent materials or combination of materials. Convenient absorbent cores comprising sponges are described in U.S. Patent No. 5,260,345 issued to DesMarais et al. On November 9, 1993, U.S. Patent No. 5,147,345 issued to Young et al. As of September 15, 1993. , U.S. Patent No. 5,1949,720 issued to DesMarais on September 22, 1992; U.S. Patent No. 5,198,472 issued to DesMarais et al. On March 30, 1993 and U.S. Patent No. 5,250,576 issued to DesMarais on October 5, 1993. The cores comprising foams are described in the European Application 0 293 208 B1. Absorbent cores comprising sponges are described in U.S. Patent Nos. 3,512,530 and 3,954,493 and French Patent No. 2,203,827. The materials selected for use as absorbent cores 34 are preferably docile, soft, comfortable, compressible and resilient to provide body fit and comfort of the primary absorbent member 30. Preferably, the absorbent core 34 is compressible in such a way that the primary absorbent member 30 It will deform under relatively small forces that are experienced during normal use. In addition to being compressible, the materials comprising the absorbent core 34 are preferably comfortable in such a manner wherein the primary absorbent member 30 is capable of providing improved fit on and around the lips and perineum. While it is generally compressible and comfortable under relatively small forces, those forces exerted during use by the female external genitalia, it is also important that the primary absorbent member is sufficiently resilient in such a way that when subjected to normal wear forces, it does not collapse permanently. Preferably, the primary absorbent member 30 will be sufficiently resilient that it will form the contour of the body to provide intimate contact with the exposed genitals of female use. Intimate contact with the exposed female genitalia helps to provide better fluid transfer from the user to the primary absorbent member without allowing the fluid to bypass and / or escape from the primary absorbent member. While the resiliency characteristics of the absorbent core 34 provide improved fit, these must be balanced against the need of the product to be both, soft and comfortable for the wearer. In a preferred embodiment of the present invention, the absorbent core 34 comprises polymers that form hydrogel and hydrophilic fibers such as air filters. Preferably, the absorbent core 34 comprises hydrogel forming polymers of between 10% and 60%. More preferably, the absorbent core 34 may include air filter of between 50% and 85%. If necessary, the absorbent core 34 can additionally include hydrophobic fibers. As shown in Figure 3, the absorbent core 34 is made in a generally cylindrical shape to provide the primary absorbent member 30 with a generally cylindrical shape. While the absorbent core 34 shown in Figure 3 has a generally circular cross-section, the absorbent core can be made in a wide variety of shapes such as rectangular, triangular, oval, square, pentagonal, U-shaped, folded into Z, etc. As shown in Figures 2 and 3, the top sheet 32 can surround the ^ absorbent core 34. The top sheet has a wider and wider length than • the absorbent core 34 (shown in Figure 5). He transverse width of the top sheet 32 is more than twice the transverse width of the absorbent core 34. This allows 0 that the longitudinal sides 45 of the topsheet 32 overlap below the absorbent core 34 to encircle the absorbent core 34 as shown in Figure 3. The costadps longitudinal members 45 of the upper sheet 32 can be secured by any convenient way to maintain the shape surrounded. Convenient ways include, but are not limited to, adhesives such as line adhesives, spiral adhesives, or knit adhesives. In a preferred embodiment shown in figures 3 and , line adhesive 51 is applied to one of the longitudinal sides 45 of the upper sheet 32 along the full length of the longitudinal extension. Alternatively, the adhesive intermittent line may be applied along the entire length of the longitudinal extension. The topsheet 32 may be associated with the absorbent core 34 in any convenient manner. Convenient ways include, but are not limited to associating the topsheet 32 with the absorbent cores 34 with adhesives such as spray adhesive, in line adhesive or spot adhesive between the topsheet 32 and the absorbent core 34. Alternatively, or additionally, the sheet upper 32 can be associated with the absorbent core 34 by entangling the fibers of the absorbent core 34 with the upper sheet 32, melting the upper sheet 32 to the absorbent core 34 with a plurality of individual discrete melting joints, or by any known means in The technique. To ensure proper fluid transfer 1 between the upper sheet 32 and the absorbent core 34, it is preferred that the upper sheet 32 be • continuously secured to the underlying absorbent core 34 through its common interface or association. By substantially continuously securing the topsheet 32 to the underlying absorbent core 34, the topsheet 32 will have a reduced tendency to separate from the absorbent core 34 during use. The separation of the absorbent core from the topsheet 32 can inhibit the transfer of fluid from the sheet • upper 32 towards the underlying absorbent core 34. Therefore, the side facing the body of the absorbent core 34 can be secured to the top sheet by adhesive, for example, while the side facing the body of the absorbent core 34 can not be secured to the topsheet 32 to retard the transfer of fluid from the absorbent core 34 to the secondary absorbent member 50. The primary absorbent member 30 it is preferably of circular or oval cross-section while the primary absorbent member 30 can generally be of any cross-sectional shape in its stress-free condition. The length PL, the width PW and the thickness PT of the primary absorbent member 30 may be of any convenient dimension. The length PL is preferably from about 2 to 35 cm, more preferably from about 10 to 35 cm, most preferably from about 20 to 35 cm. Preferably the length PL of the primary absorbent member 30 can generally be equal to the length SL of the secondary absorbent member 50. The width PW is preferably from about 0.5 to 5 cm, more preferably from about 1 to about 5 cm and most preferably from about 1 to about 5 cm. preferably from about 2 to about 4 cm. The width PW of the primary absorbent member 30 can be less than the width SW of the secondary absorbent member 50. The thickness PT is preferably from about 0.2 to about 2. 0 cm, more preferably from about 0.2 to 1.5 cm, and most preferably from about 0.4 to 1.2 cm. Preferably the thickness PT of the primary absorbent member 30 may be larger than the thickness ST of the secondary absorbent member 50. A ratio of the thickness PT over the width PW, or the ratio (PT / PW) can be between 0.05 and 1.5. Preferably, the ratio can be between 0.08 and 1.00. More preferably, the ratio can be between 0.08 and 0.5. The size of the primary absorbent member 30 is determined by the following test. A measuring comparator is necessary, and specifically the Peacock 'Gage Model No. 307, available from Ozaki Manufacturing Co., LTD. The measuring comparator must have a circular comparator foot made of aluminum and it must have a weight of 9.0 grams and a contact surface of 16 cm2. The measure comparator is set to zeros. A weight of 60.0 grams of stainless steel is placed on the bolt • that extends above the dial of the comparator. The comparator foot is extended and the primary absorbent member and the primary absorbent member is placed below the surface of the undergarment on the base plate. The primary absorbent member is placed on the base plate such that when the foot is lowered it is in the region of the primary absorbent member from which the measurement is required. Try to soften or prevent any wrinkles in the primary absorbent member. Gently lower the foot on the primary absorbent member. Determine the gauge of the primary absorbent member by reading the comparator quadrant from 5 to 10 seconds after the foot came into contact with the primary absorbent member. The primary absorbent member 30 of the present invention is preferably relatively comfortable. It is preferred to keep the primary absorbent member relatively comfortable in such a way that it easily fits in the labial groove during use. It has been found that a primary absorbent member having the width and / or thickness is able to fit comfortably next to the labial area. While the primary absorbent members have been described above as having width or thickness greater than the width or thickness greater than above, they can also fit within the labial groove if they are sufficiently comfortable. It is not necessary for the entire primary absorbent member to fit within the labial groove, however, a portion of the primary absorbent member is preferably able to fit within the labial groove. The primary absorbent member 30 may include optional elements. The primary absorbent member 30 may optionally comprise a resilient member with the absorbent core 34. The resilient member may comprise a single member or a plurality of individual members. Suitable materials that can be used as resilient members include, but are not limited to, nylon, polypropylene, polyurethane, polyethylene, synthetic polyester rubber, and other synthetic materials such as formed films or natural materials such as rubber, sponges, and the like. or any suitable material that is capable of withstanding the collapse under normal conditions of sanitary napkins during use. The resilient member can be manufactured in a wide variety of shapes such as rectangular, triangular, oval, square, pentagonal, U-shaped, Z-shaped, etc. The resilient member may extend through the full length of the primary absorbent member 30. The resilient member may only extend through a portion of the length of the primary absorbent member 30. The resilient member may be positioned within the first region. of end 27, central region 28, second end region 28 or any combination of those above. For example, the resilient member may be placed in either the first end region 27 or the second end region 29 of the primary absorbent member, both the first end region 27 and the second end region 29 of the primary absorbent member. 30, in the central region 28 of the primary absorbent member, or in the central region 28 and the end regions 27, 29 of the primary absorbent member 30. Optionally, the primary absorbent member 30 may comprise an acquisition layer placed between the top sheet 32 and the absorbent core 34. The acquisition layer can serve several functions including improving the wicking effect of the exudates on and in the absorbent core 34. Improving the wicking effect of the -exudates, the acquisition layer provides a still distribution. greater exudates through the entire absorbent core. The acquisition layer may be comprised of several different materials including woven or non-woven webs of ^ Synthetic fibers including polyesters, polypropylene or polyethylene; natural fibers that include cotton or cellulose; mixtures of such fibers, or any equivalent materials or combinations of materials. Examples of sanitary napkins having an acquisition layer and a topsheet are more fully described in U.S. Patent No. 4,950,264 issued to Osborn and Publication PCT No. W093 / 11725 published June 24, 1993 to names of Cree and others. Each of these references are incorporated herein by reference. In a preferred embodiment, the acquisition layer may be joined to the top sheet by any of the conventional means for joining frames together, more preferably by fusion bonds as more fully described in the Cree application referenced above. Referring to Figures 1-3A, the second necessary constituent of the composite sanitary napkin 20 of the present invention is the secondary absorbent member (base member) 50. The secondary absorbent member 50 generally has a rectangular shape extending in the direction longitudinal along the line longitudinal center L. In a preferred embodiment, the longitudinal extension SL can generally be equal to the longitudinal extension PL of the primary absorbent member 30. The transverse width SW can generally be wider than the transverse width PW of the primary absorbent member 30. secondary absorbent member 50 has the longitudinal sides 21 and the transverse ends 22. In a preferred embodiment shown in Figure 1, a pair of fins 33 extend outwardly from the longitudinal sides 21 in the central region 28. The secondary absorbent member 50 Preferably, it comprises a fluid-permeable fluid-permeable body sheet or a fluid-permeable sheet 52, a waterproof sheet against the undergarment. * fluid or backsheet impervious to fluid 54 attached to top sheet 52, and an element secondary absorber 56 co-extruded between top sheet 52 and back sheet 54. Top sheet 52 may be any fluid-permeable material commonly used in sanitary napkins, disposable diapers, and the like. It may be any of the materials described above while being useful in the top sheet 32 of the primary absorbent member 30. A preferred top sheet 52 comprises a film formed with openings. Films formed with openings for the daughter are preferred -superior because they are permeable to body exudates and not yet absorbent and i have a reduced tendency to allow fluids to pass back through it and rewet the user's skin. Therefore, the surface of the formed film that is in contact with the body remains dry, thereby reducing the staining of the body and creating a more comfortable feeling for the user. Suitable shaped films are described in U.S. Patent No. 3,929,135 issued to Thompson, December 30, 1975; U.S. Patent No. 4,324,246 issued to Mullane et al., April 13, 1982; U.S. Patent No. 4,342,314 issued to Radel et al. On August 3, 1982; Patent of the States No. 4,463,045 issued to Ahr et al. On July 31, 1984 and United States Patent No. 5,006,394 issued to Baird on April 9, 1991. Each of these patents is incorporated herein by reference. The preferred top sheet for the primary absorbent member of the present invention is a formed film described in one or more of the above patents and marketed in sanitary napkins by Procter . & Gamble Company of Cincinnati, Ohio as "DRI-WEAVE". The absorbent element 56 can be any absorbent material commonly used in sanitary napkins, disposable diapers and the like. It can be any of the materials described above while being useful in the absorbent core 34 of the primary absorbent member 30. As a practical matter, most body fluids are absorbed by and are contained within the absorbent core 34 of the primary absorbent member 30. A greater function of the primary absorbent member 50 -is for protecting the wearer's underwear against soiling by absorbed fluids which may be expelled from the primary absorbent member 30 or inadvertently diverted from the primary absorbent member 30. The overall absorbent capacity of the absorbent member 56 may be, therefore, somehow less than that of the absorbent core 34. Because the absorbent core 34 is preferably intended to absorb most of substantially all of the body fluids during use, its absorbent capacity will be for some reason, if not significantly greater than that of the absorbent member 56. Because the absorbent member 56 of the secondary absorbent member 50 performs a function different from that of the absorbent core 34, the absorbent member 56 may be, and more preferably is, for some reason thinner and less bulky than the absorbent core 34. Because the absorbent element 56 has different These requirements are different from those of the absorbent core 34, it may be formed of different materials. For example, multiple or single folds of tissue paper as commonly used in terry cloth or toilet paper may be used to form the absorbent element 56. Preferably, the absorbent member 56 is formed from about 1 to about 5 folds of tissue paper. The tissue paper comprises one or more folds that have a basis weight of from a! from about 24 to about 48 grams per square meter and a bulk density of from 0.10 to about 0.12 grams per cubic centimeter as was done by the process described in U.S. Patent No. 3,301,746 issued to Sanford and Sisson, January 31, 1967 and whose patent, which is hereby incorporated by reference, has been found to be very satisfactory for use as an absorbent 56. Latex and moisture resistant resins fasteners may be, and preferably are, used. to provide additional strength to the tissue paper used in the absorbent element. The tissue paper made by the process described in U.S. Patent No. 3,994,771 issued to Morgan et al. On November 30, 1976, and whose patent is incorporated herein by reference, can also be used for good advantage as an absorbent 56 The absorbent element may have any convenient shape that includes, but is not limited to, oval, hourglass, dog bone, asymmetric, etc. In a preferred embodiment shown in Figure 1, the absorbent member 56 is generally rectangle-like surrounded by longitudinal edges 55 and transverse edges 57. The absorbent member 56 also has a longitudinal extension CL, a transverse width CW and a thickness CT. The longitudinal extension CL may be shorter than the longitudinal extension PL and SL. The extension CL can be from about 10 about 33 cm, preferably from about 15 to about 33 cm. The transverse width CW may be wider than the transverse width PW of the primary absorbent member 30 at least in the central region 28 (e.g., the crotch region corresponding to the crotch region of the undergarment when using the compound sanitary napkin). More preferably, the transverse width CW may be wider than the transverse width PW of the primary absorbent member 30 throughout the entire length. The width CW can be from about 3 to about 12 cm, preferably from about 4 to about 10 cm, more preferably from about 5 to about 8 cm. Figures 10 and 11 show the alternative form of the composite sanitary napkin and the secondary absorbent element. The composite sanitary napkin 90 shown in Figure 10 has a narrower portion (for example the crotch region) to the core in the longitudinal direction, and has no fins on both longitudinal sides. The secondary absorbent member 95 of the composite sanitary napkin 90 may have a patch-type absorbent member 91 generally positioned in the crotch region as shown in Figure 10. The patch-type absorbent member 91 may have an oval shape which it has the widest portion to the nucleus in the longitudinal direction. The broad portion of the absorbent member 91 may preferably coincide with the narrower crotch region of the sanitary composite pad 90. The sanitary composite pad 92 shown in Fig. 11 has rear fins 94 in addition to the fins 33 placed over the region of the bag. crotch. The secondary absorbent member 96 of the composite sanitary napkin 92 shown in Figure 11 may have a formed absorbent member 93 having the narrowest portion in the crotch region of the sanitary napkin 92. The narrower portion of the absorbent member formed 93 may preferably coincide with the crotch region of the composite sanitary napkin 92. In both embodiments, the transverse width CW is preferably wider than the transverse width PW of the primary absorbent member 30 in the crotch region of the composite sanitary napkin. Preferably, the width PW can be less than about 80% of the width CW. More preferably, the width PW can be less than about 70% of the width CW. The topsheet 54 is impervious to fluid (eg, menstrual bleedings and / or urine) and preferably is made of a thin plastic film, although other flexible fluid impervious materials may also be used. As used herein, the term "flexible" refers to materials that are compliant and readily conform to the contours and general shape of! body. In use, the • backsheet 54 is interposed between the absorbent member 56 and the undergarments of the user's underwear. The function of the upper sheet 54 is to prevent exudates that can be expelled from or inadvertently deviating from the element primary absorber 30 and that the exudates absorbed and contained in the absorbent element 56 come into contact with and soiled the wearer's undergarments. The upper sheet 54 then may comprise a woven or non-woven material, films -polymeric, such as polyethylene or polypropylene thermoplastic films, or . composite materials such as a nonwoven material covered with film.

Preferably, the backsheet is a polyethylene film having a thickness from 0.012 mm (0.5 mil) to about 0.015 mm (2.0 mil). Exemplary polyethylene films are manufactured by Clopay Corporation of Cincinnati, Ohio, under the designation P-18-0401 and by Ethyl Corporation, Visqueen Division, of Terre Haute, Indiana under the designation XP-39385. The backsheet is preferably surrounded and / or finished in matt to provide a more similar appearance to the underwear article. Additionally the backsheet can allow the vapors to escape from the absorbent member 56 (eg breathable) while still preventing the exudates from passing through the backsheet 54. The shape of the secondary absorbent member 50 can be generally rectangular surrounded by the longitudinal sides 21 and the transverse ends 22. Other convenient shapes include but are not limited to ovals, hourglass, dog bone, asymmetric, etc. the secondary absorbent core 50 may have fins 33 each of which are adjacent to and extend laterally from the longitudinal sides 21 of the secondary absorbent member 50 in the central region 28 as shown in Figure 1. The fins 33 are configured to adorn the wearer's panties in the crotch region in such a way that the fins are arranged between the edges of the wearer's panties and the wearer's thighs. The fins 33 serve at least two purposes. First, the flaps 33 help to prevent staining of the wearer's body and of the panties by menstrual fluids, preferably by forming a double-walled barrier along the edges of the panty. Second, the fins 33 are preferably provided with fastening means, as described above, on the facing surface of the undergarment so that the fins 33 can be folded posteriorly under the panty and fastened to the underpants. the face in front of the panty underwear. In this way, the fins 33 serve to keep the sanitary napkin 20 properly placed in the pantyhose. In a preferred embodiment, the fins 33 are comprised of a top sheet and a back sheet. Additionally, the flaps 33 are preferably unitary to the sheets of the secondary absorbent element 50. In other words, the upper sheet 52 of the secondary absorbent member 50 and the backsheet 54 of the secondary absorbent member can simply extend laterally outward from the sides. longitudinals 21 to form the fins 33. However, the fins 33 need not be unitary with the secondary absorbent member 50, but they may be separate elements that are fixed to the secondary absorbent member 50. Additionally, the fins 33 may be comprised of a substrate single or other laminated configurations. However, it is preferable that the fins 33 have a backsheet impervious to the fluid to prevent the exudates reaching the fins from soiling the edges of the wearer's panties. Additionally, it is preferable that the fins 33 may be provided with an absorbent member, at least for a point beyond the edges of the wearer's panties. Theoretically, only a relatively small amount of menstrual fluids must reach the fins 33, therefore, only a relatively small amount of absorbent material is desired. Accordingly, the fins 33 preferably have at least some absorbent material in order to prevent any exudate reaching the fins 33 from being able to flow further away from the unprotected areas. The absorbent material can be a tissue or an extension of the absorbent element 56. Preferably, the absorbent material in the fins 33 is relatively highly flexible relative. A number of sanitary napkins having suitable or adaptable fins for use with the secondary absorbent member 50 of the composite sanitary napkin 20 of the present invention are disclosed in U.S. Patent No. 4,687,478 issued to Van Tilburg, on August 18. of 1987; The Patent of the United States No. 4,589,876 issued to Van Tilburg on May 20, 1986; and U.S. Patent No. 4,608,047 issued to Mattingly on August 26, 1986. Each of these patents is incorporated herein by reference. Optionally, the secondary absorbent member 50 may comprise components that naturally surround the edges of a wearer's panties. A sanitary napkin having components that naturally envelop the sides of a wearer's panties suitable for use with the secondary absorbent member 50 of the composite sanitary napkin 20 of the present invention is disclosed in U.S. Patent No. 5,584,829 issued to Lavash et al. on December 17, 1996 and U.S. Patent No. 5,558,663 issued to Weinberger et al. on September 24, 1996. The disclosures of preceding publications are incorporated herein by reference. Preferably, the secondary absorbent member 50 is provided with a support means or fastening means, such as adhesive means 58 and 62. The adhesive fastening means 58 provides a means for securing the sanitary pad composed 20 in the portion of the adhesive. the crotch of the underwear garment or pant of the user. The adhesive attachment means 62 provides a means for securing the fins 33 of the sanitary napkin 2 (5) to the side facing the underwear of the panty so that the flaps 33 can be folded down posteriorly underneath from • the panties. Therefore, a portion or all of the exterior or surface facing the body of the upper sheet 54 may be covered with adhesive. In a preferred embodiment, at least a portion of the adhesive 58 may be placed on the surface of the garment of underwear of the upper sheet 54 along the longitudinal direction of the member secondary absorber 50 and may have, but not limit to, a line shape along the longitudinal direction. The adhesive 62 may be placed on the surface of the undergarment of the backsheet 54 of the flaps 33 and may have, but not be limited to, a rectangle shape. Any adhesive or glue used in the art for such purposes can be used there for the adhesive, being preferred with pressure sensitive adhesives. Suitable adhesives are Century A-305-IV manufactured by Century Adhesives Corporation of Coiumbus, Ohio, and Instant Lock 34-2823 manufactured by National Starch and Chemical Company of Bridgewater, NJ. Suitable adhesive fasteners are also described in U.S. Patent No. 4,917,697. The pressure sensitive adhesive is typically covered with a removable release protector 59 and 63 in order to keep the drying adhesive away from adhering to a surface other than the crotch portion of the panty before use. Suitable release protectors are also described in U.S. Patent No. 4,917,697 referred to above. Any commercially available removable release liner commonly used for such purpose can be used here. Non-limiting examples of removable release protectors are BL30MG-A Silox "E1 / 0 and BL30MG-A Silox 4P /, both are manufactured by Akrosil Corporation of Menasha, W. The composite sanitary napkin 20 of the present invention is used by stirring the release protector 59 and 63 and thereafter placing the sanitary napkin 20 in a panty so that the adhesive 58 and the adhesive 62 make contact with the panty The adhesives 58 and 62 hold the sanitary napkin in position on the panty during use, the upper sheet 52 and the rear sheet 54 of the secondary absorbent member 50 can be joined together in any possible way.

J52 may be attached to the backsheet 54 along the periphery 64 or may be attached to the backsheet in all regions excluding the region where the absorbent element 56 exists. In the region where the absorbent member 56 exists, the upper sheet 52 and the back sheet 54 each may be attached to the absorbent element 56. Convenient ways include, but are not limited to, applying pressure, heat, heat and pressure or adhesives such as line adhesives, spiral adhesives and adhesives. knitted adhesives. In a preferred embodiment shown in Figure 1, the topsheet 52 and the backsheet 54 can be joined by applying heat along the periphery 64 of the sanitary napkin 20.

The length SL, the width SW and the thickness ST of the secondary absorbent member 50 may be of any convenient dimension. The length SL is preferably from about 5 to 35 cm, more preferably from about to 35 cm, and more preferably from about 20 to 35 cm. Preferably, the length SL of the secondary absorbent member 50 can generally be equal to the length PL of the secondary absorbent member 30. The width SW is preferably from about 4 to 13 cm, more preferably from about 5 to about 11 cm, and most preferably from around 6 to about 9 cm. The secondary absorbent member 50 of the present invention is preferably relatively thin and flexible. The thickness ST preferably is from about 0.1 to 2.0 cm. more preferably from about 0.1 to 1.0 cm, and most preferably from about 0.1 to 0.4 cm. Preferably, the thickness ST of the secondary absorbent member 50 can be less than the thickness PT of the primary absorbent member 30. The secondary absorbent member (base member) 50 can optionally be manufactured without an absorbent member 56. Because most if not all bodily fluids are preferably absorbed by and are contained within the absorbent core 34 of the absorbent core 34 of the primary absorbent member 30, the base member 50 only needs to protect the wearer's undergarment from staining by relatively small amounts of fluid. which can be expelled from the primary absorbent member 30 or which can be inadvertently diverted from the primary absorbent element 30. Accordingly, because expected quantities of fluids that can come into contact with the base member are relatively small, it can a base element is not necessary to contain the fluids inside the mbre of base 50 and prevent them from soiling the undergarments of the wearer.

To form the composite sanitary napkin 20 of the present invention, the primary absorbent member 30 and the secondary absorbent member 50 are joined by attachment means generally indicated 70 in Figures 1-3, 6 and 7. The attachment means 70 for attaching the primary absorbent member 30 and the secondary absorbent member 50 within the composite sanitary napkin 20 of the present invention with sufficient tenacity so that the primary absorbent member 30 and the secondary absorbent member 50 are not disconnected during use. Any convenient attachment means such as adhesive fastening, pressure fastening, heat fastening, or ultrasonic fastening can be used. The primary absorbent member 30 may be fixed to said secondary absorbent member 50 by the attachment means 70 along the entire common length. Alternatively, the primary absorbent member 30 may be fixed to said secondary absorbent member 50 intermittently along the common length. In a preferred embodiment shown in Figures 1-3, 6 and 7, the primary absorbent member 30 is fixed to the secondary absorbent member 50 by the attachment means 70 which includes a first attachment means 72 and the second attachment means 74. • -. ., - £ | ppmer attachment means 72 includes application of heat to the transverse ends * 22 and 25 overlapped in a plurality of discrete points. By applying pressure to the overlapped transverse ends 22 and 25, the topsheet 32 of the primary absorbent member 30, the topsheet 52 and backsheet 54 of the secondary absorbent member 50 are fixed together at the overlapped transverse ends 22 and 25. Alternatively , the first attachment means 72 may include application of heat at a plurality of discrete points, line or area. While the application of heat works well to join smooth layers, heat transfer between the layers to join the layers can be worse as the layers become thinner. The preferred embodiment shown in Figure 2, because the longitudinal sides 45 of the upper sheet 32 of the primary absorbent member 30 are overlapping one another below the absorbent core 34, five layers comprising layers of the upper sheet 32, one layer the upper sheet 52 are joined together. and a layer of the backsheet 54. If the top sheet 32 comprises two layers having the formed film 36 and the non-woven material 37, eight layers have to be joined together as shown in Figure 7.

"While the layers become thin, it is preferable to apply pressure, or pressure and pressure to join the layers. Alternatively, the first attachment means 72 may include the application of adhesive between the layers, or the application of combination of pressure, heat and adhesive. In a preferred embodiment, the adhesive 72A can be affixed to the inner surface of the upper sheet 32 at the transverse end 46 as shown in Figures 2, 5 and 7. Alternatively, the adhesive 72B can be applied between the formed film 36 and the nonwoven material 37 at the transverse ends 44 and 48 as shown in Figure 7. Alternatively, both of the adhesives 72A and 72B may be applied. The second attachment means 74 includes adhesive application such as spiral adhesive, line adhesive or knit adhesive between the absorbent member * - primary 30 and the secondary absorbent member 50. As shown in Figure 6, in a preferred embodiment, the spiral adhesive 74 as the second attachment means is Is applied continuously between the primary absorbent member 30 and the secondary absorbent member 50. When it is desired that the primary absorbent member 30 and the secondary absorbent member 50 be fixed to each other along the entire common length, it is preferable to use the spiral adhesive because the application of the spiral adhesive prevents the absorbent members 30 and 50 from being fixed intermittently. The primary absorbent member 30 and the secondary absorbent member 50 are preferably fixed in the AW width narrower than the transverse width PW of the primary absorbent member 30. Preferably, the width AW can be 70% of the width PW. This allows the primary absorbent member 30 to conform to the shape of the female body and to the movement of the female body. The composite sanitary napkin 20 may include a variety of alternatives and / or options. The primary absorbent member 30 may comprise a fluid barrier 35 as shown in Figure 8. The fluid barrier 35 may be placed on the side of the lower half of the absorbent core 34 to inhibit the fluid from transferring from the absorbent core. towards the secondary absorbent member 50. The fluid barrier 35 tends to contain fluids absorbed within the absorbent core 34 and may be constructed of materials that have the same properties as those of the upper sheet impermeable to the fluid on e! absorbent secondary member 50 described above. The fluid barrier 35 may extend along the entire length of the primary absorbent member 30 or may extend only in the central region 28 of the primary absorbent member 30, or in the first end region 27 and the second end region. 29. Alternatively, the topsheet 32 of the primary absorbent member 30 may comprise a sheet having a fluid-permeable zone 76 and a fluid-impermeable region 78. When the topsheet 32 comprises a formed film, the fluid-permeable zone. 76 may be an area with openings and the fluid impervious zone 78 may be an area without openings. As shown in Figure 9, the fluid permeable zone 76 of the topsheet 32 can be placed on the lower half of the side of the absorbent core 34 to inhibit the transfer fluid from the absorbent core to the secondary absorbent member 50. The fluid-permeable zone 76 tends to contain the fluids absorbed within the absorbent core 34. The composite sanitary napkin 20 can be extensible. The individual components of the primary absorbent member 30 and the secondary absorbent member 50 may be comprised of components that are extensible (preferably capable of elongating) particularly in the longitudinal direction where the sanitary towel 20 is worn. Preferably, the composite towel 20 is able to stretch in the longitudinal direction between about 15% and about 40% of the non-elongated length. This extensibility provides better fit in use, comfort, and reduced staining when the sanitary compound pad is attached to the wearer's undergarments. Preferably, the secondary absorbent member 50 is comprised of components that are also extensible in the lateral direction when the composite sanitary napkin 20 is dressed. Preferably, the composite sanitary napkin 20 is elongated layers in the lateral direction between about 15% and about 40% of the non-elongated length. The topsheet 32 of both primary absorbent member 30 and secondary absorbent member 50 may comprise a - polymeric, fluid permeable, three-dimensional, elastic, as disclosed in United States Patent No. 5,366,782 issued to Curro and others on 22 october 1994 and which is here incorporated by reference. A particularly preferred extensible top sheet is an extended adhesive film known as Formula # 198-388 manufactured by Fíndley Adhesives Company of Wauwatosa, Wisconsin. Sanitary napkins having extensible components are described in United States Patent No. 5,611,790 issued to Osborn et al. On March 18, 1997, and PCT Publication No. WO93 / 01786 published February 4, 1993 to the names of Osborn and others. The disclosures of the preceding publications are incorporated herein by reference. The sanitary compound pad 20 can be shaped with the female body. Because the primary absorbent member 30 preferably has the shape and size such that it will fit adjacent to the labial area, the primary absorbent member 30 will at least partially reside within the lips. As shown in Figure 10, when the sanitary napkin 20 is worn by the woman and supported by an undergarment 82, a portion of the primary absorbent member 30 will preferably fit adjacent to the lip area during use. In contrast, a major function of the secondary absorbent member 50 is to protect the garment from underwear against staining by absorbed fluids which can be expelled from the primary absorbent member 30 or which can inadvertently be deflected from the primary absorbent member 30. The absorbent member secondary 50 is preferably remote from the body such that the secondary absorbent member 50 will not touch the body. The shape of the primary absorbent member 30 has the shape and size so that the secondary absorbent member 50 is remote from the body to secure the space 80 between the body and the secondary absorbent member 50. This allows the longitudinal sides of the secondary absorbent member 50 to remain White. The sanitary composite pad 20 can absorb body fluids. The total absorbent capacity of the primary absorbent member 30 should be compatible with the proposed exudate load for the sanitary composite pad 20. Additionally, the absorbent capacity of the absorbent core 30 can be varied to accommodate users that vary in the expected amount of exudate fluid. . Typically, "exudate fluid of between 2 and 20 grams is expected during a normal period of sanitary pad use." When the sanitary napkin 20 is exposed to such a fluid load of between 2 and 20 grams, the primary absorbent member 30 can absorb. 80% of the fluid between 2 and 20 grams in a current use situation Additionally, when the sanitary composite pad 20 is exposed to the fluid load of between 20 and 30 grams exceeding the normal capacity, the primary absorbent member 30 can absorb 70% of the fluid between 20 and 30 grams Because the primary absorbent member 30 has the capacity to absorb at least 70% of discharged fluid of between 2 and 30 grams when the sanitary napkin is applied to the female body and used, the The primary absorbent member 30 having such a capacity allows the longitudinal sides of the secondary absorbent member 50 to remain white.This provides consumers with a visual signal that increases the confidence in the absorbency and performance of the run-off tests of the sanitary towel product. The primary absorbent member 30 preferably comprises hydrogel forming polymers to increase the absorption capacity of the primary absorbent member 30. The largest hydrogel forming polymers that the primary absorbent member contains, the greater absorption capacity that the primary member 30 has. Because the hydrogel forming polymers are sweated after the polymers absorb fluids, the primary absorbent member 30 expands in the transverse direction and thickness. This expansion of the primary absorbent member 30 • provides more comfort and fit between the primary absorbent member 30 and the female body. However, many polymers that form hydrogel cause gel blocking problems that result in decreased absorption ability. More importantly, many hydrogel forming polymers, when absorbing fluids, cause the primary absorbent member 30 to have a straight cylinder shape that will not bend. • easily without high bending force. When this occurs, the primary absorbent member 30 can not adjust the shape of curvature of the female body because the transverse ends of composite sanitary napkin 20 tend to be away from the body.

Therefore, appropriate amounts of polymers that form hydrogel are preferred from the point of view of the absorption, compliance and adjustment ability of the towel Compound sanitary having the primary absorbent member. It may be desirable to provide a sanitary composite pad having a primary absorbent member with varying degrees of width or gauge throughout its entire length. For example, the primary absorbent member may be relatively thinner in the central region as opposed to the end regions. Alternatively, the primary absorbent member may be relatively thinner in the central region as opposed to the end regions. While the particular embodiments of the present invention have been described and illustrated, it will be obvious to those skilled in the art that various other changes and modifications may be made without departing from the spirit and scope of the present invention. Therefore, it is intended to protect in the appended claims all those changes and modifications that are within the scope of the present invention.
