Description

Compound sanitary napkin to match body {BODY FITTING COMPOUND SANITARY NAPKIN}

Disposable sanitary napkins, in their simplest form, are absorbent elements (often called absorbent cores) placed between a fluid permeable body facing sheet (often referred to as a topsheet) and a fluid impermeable garment-facing sheet (often referred to as a backsheet). It includes. Of course, the absorbent element is intended to receive and retain physiological blood and other vaginal discharges. The body facing sheet is intended to provide a somewhat comfortable and dry contact to the body surface while allowing free passage of fluid through the absorbent element therethrough. The garment-facing sheet is intended to prevent the discharge of menstrual blood or other vaginal discharge from or out of the absorbent element to contaminate the user's garment. In addition to the three functional elements mentioned above, disposable sanitary napkins are generally provided with means for supporting the device proximate the user's crotch region even when the user is moving, where the disposable sanitary napkin most effectively performs its intended function. can do. Typically the sanitary napkin is provided with adhesive attachment means for securing the device to the inner crotch portion of the user's undergarment.

While previously known sanitary napkins perform their intended functions, each conventional design has certain deficiencies in one or more of: absorption of body fluids, protection of the user's garment from contamination, and / or physical comfort to the user. .

With regard to disposable sanitary napkins, two or more general classes currently exist. One class is identified as intended to absorb medium to high menstrual blood flow. Such sanitary napkins provide a relatively high absorption capacity. Absorption capacity is usually obtained by providing a sanitary napkin having a relatively thick and bulky absorbent member. Although having a relatively high absorption capacity, the large volume of the absorbent member can cause some discomfort when worn. The second class of sanitary napkins is intended for low or low menstrual blood flow and is commonly referred to as a pantliner or pantshield. This class of sanitary napkins as a group is thinner, somewhat more flexible and generally more comfortable than the first class of sanitary napkins. However, the second class of sanitary napkins typically lacks the absorbent capacity of the first class of sanitary napkins.

One effort to provide the benefits of two classes of sanitary napkins previously described to a single composite sanitary napkin is disclosed in US Pat. No. 4,425,130, issued January 10, 1984 to Desmarais. Desmarice's composite sanitary napkin comprises a first menstrual blood pad and a panty protector connected to each other at their corresponding ends in a manner that is essentially free of two constructs moving relative to each other along its entire normal length. In use, the relative freedom of movement between the first menstrual blood pad and the panty protector keeps the first menstrual blood pad proximal to the crotch region of the user while the panty protector continues to engage the undergarment of the user. While relative freedom between the first menstrual blood pad and the panty protector is provided to maintain the first menstrual blood pad adjacent to the user's crotch region, this freedom of movement is such that the first menstrual blood pad is positioned off the side edge of the panty protector. Moving in the direction can lead to a lack of stability while providing an opportunity to contaminate the user's undergarment.

Prior art absorbent products such as sanitary napkins have solved some problems in obtaining composite sanitary napkins, but did not solve the problem to the extent of the present invention or in the manner of the present invention. After all, the first object of the present invention is to provide an improved composite sanitary napkin.

The present invention relates to a composite sanitary napkin that conforms to the body, indicating absorption of body fluids, protection from contamination of the user garments, and physical comfort for the user. As used herein, the term "physiological zone" is intended to absorb and retain various secretions (eg, blood, menstrual blood and urine) that are worn by women and excreted from the body adjacent to the vulva area and are used once. Represents an absorbent product that is later discarded (ie, not washed or otherwise recovered or reused). The term "composite sanitary napkin" as used herein refers to a sanitary napkin comprising separate constructs connected to each other to form an integral structure. In addition, interlabial tools that partially and externally exist within the wearer's vestibule are within the scope of the present invention. As used herein, the term "vulva" refers to an externally visible female genitalia and is limited to the labia majora, labia minora, clitoris and vestibular.

1 to 3, one preferred embodiment of the composite sanitary napkin 20 of the present invention is shown. The composite sanitary napkin 20 has two surfaces, a body contact or opposing surface 20A and a garment contact or opposing surface 20B. The composite sanitary napkin 20 has a first distal end 27, a central portion 28, a second distal end 29, a longitudinal side 16 and a transverse end 18. The composite sanitary napkin 20 has two centerlines, a longitudinal centerline L and a transverse centerline T. FIG. The term "longitudinal" as used herein refers to the line, axis, or direction in the plane of the composite sanitary napkin approximately centered with the vertical plane that divides the standing wearer into the left and right body when the composite sanitary napkin is worn. . The terms "lateral" or "lateral" as used herein may be interchanged and refer to a line, axis, or direction that is present in the plane of a composite sanitary napkin that is generally perpendicular to the longitudinal direction.

As can be seen in FIGS. 1 to 3, the composite sanitary napkin 20 includes a first absorbent member 30 and a second absorbent member (base member) 50 connected together by a connecting means 70. do. Each of the first absorbent member and the second absorbent member has a corresponding body facing and garment facing surface. The first absorbent member 30 has a longitudinal side portion 24 and a transverse end 25, which together form a perimeter 26 of the first absorbent member 30. The first absorbent member 30 also has a length PL in the longitudinal direction, a width PW in the lateral direction and a thickness PT. The second absorbent member 50 has a longitudinal side portion 21 and a longitudinal end 22, which together form the second absorbent member 50 and the perimeter 23 of the composite sanitary napkin 20. The second absorbing member 50 has a length SL in the longitudinal direction, a width SW in the lateral direction, and a thickness ST. As shown in FIG. 1, preferably, the composite sanitary napkin 20 has a flap 33 extending from the longitudinal side 21 of the second absorbent member 50 at the center of the composite sanitary napkin 20. Has

The first absorbent member 30, as its name suggests, is a component of the composite sanitary napkin 20 intended to absorb most of the body fluids discharged by the user. The first absorbent member 30 generally has a rectangular shape extending longitudinally along the longitudinal center line L. As shown in FIG. In a preferred aspect, the longitudinal length PL may generally be equal to the longitudinal length SL of the second absorbent member 50. The transverse width PW may generally be narrower than the transverse width SW of the second absorbent member 50. The first absorbent member 30 includes a first absorbent element such as the absorbent core 34 and a fluid permeable cover such as the fluid permeable top sheet 32 overlying the absorbent core 34.

The upper sheet 32 is preferably flexible, has a good feel, and is not irritating to the wearer's skin. In addition, the top sheet 32 is fluid permeable and allows fluid to easily penetrate through its thickness. Suitable topsheets 32 include woven and nonwoven fabrics; Polymeric materials such as perforated thermoplastic films, perforated plastic films and hydroformed thermoplastic films; Reticulated thermoplastic film; And a wide range of materials such as thermoplastic scrims. Suitable fabrics and nonwovens can be composed of natural fibers (eg, wood or cotton fibers), synthetic fibers (eg, polymeric fibers such as polyester, polypropylene, or polyethylene fibers) or of natural and synthetic fibers. It can be constructed from a combination. Preferred top sheets include perforated films. Perforated molded films are preferred for topsheets because they are permeable to body secretions but are nonabsorbent and have a reduced tendency for fluid to return to or rewet the wearer's skin. Thus, the surface of the molded film in contact with the body remains dry, preventing body contamination and creating a more comfortable feel for the wearer. Suitable molded films are described in US Pat. No. 3,929,135 to Thomson, Dec. 30, 1975; U.S. Patent No. 4,324,246, issued to Mullan et al. On April 13, 1982; US Patent No. 4,342,314 to Radel et al. On August 3, 1982; US Patent No. 4,463,045, issued to Ahr et al. On July 31, 1984; And US Pat. No. 5,006,394 to Biard, dated April 9, 1991. Each of these patents is incorporated herein by reference. Preferred topsheets for the first absorbent member of the present invention are described in one or more of the above patents and are referred to as "DRIWEAVE" by The Procter & Gamble Company of Cincinnati, Ohio. It is a molded film sold under the trade name.

The body or exposed surface of the molded film upper sheet may pass through the upper sheet as compared to the case where the body surface is not hydrophilic to reduce the likelihood that physiological blood flows into the absorbent core or flows out of the upper sheet without being absorbed by the absorbent core. It may be hydrophilic to help deliver fluids faster. In a preferred embodiment, the surfactants may be added to the molded film upper sheet as described in PCT Publication No. WO 93/09741, published May 23, 1993, in the name of Aziz et al., Incorporated herein by reference. It can be incorporated into polymeric materials. Alternatively, the body surface of the top sheet may be made hydrophilic by treatment with a surfactant, as described in US Pat. No. 4,950,264, issued to Osborn on August 21, 1990, incorporated herein by reference. .

In a preferred aspect of the present invention, as shown in FIG. 4, the top sheet 32 may include a nonwoven fabric 37 and a molded film 36 overlying the nonwoven fabric 37. The molding film 36 is second from the first surface 38 facing outwardly, the second surface 39 and the first surface 38 opposite the nonwoven fabric 37 and the absorbent core 34. It has an opening 42 extending to the surface 39. The area of the opening 42 in the second surface 39 adjacent the absorbent core 34 is generally smaller than the area of the opening 42 in the first surface 38. Since the opening area of the first surface 38 is generally larger than the opening area of the second surface 39, fluid can easily penetrate the top sheet 32 towards the absorbent core 34. However, this prevents fluid trapped in the absorbent core 34 from being transferred outward from the absorbent core 34 and inhibits rewetting of the wearer's surface. The nonwoven 37 overlies the second surface 39 of the molded film. Each of the molded film 36 and the nonwoven fabric 37 has a rectangle when the molded film 36 and the nonwoven fabric 37 are not folded as shown in FIG. 5. Top sheet 32 has a longitudinal side 45 and a transverse end 46. The molded film 36 has a corresponding longitudinal side 43 and a transverse end 44, and the nonwoven 37 has a corresponding longitudinal side 47 and a transverse end 48. Molded film 36 and nonwoven 37 may be superimposed by any suitable manner. Preferably, the molding film 36 and the nonwoven 37 may be connected to one another along the lateral side 45 by a plurality of separate dots 49. The separated dots can be formed by applying pressure, heat, pressure and heat, and / or adhesive. Alternatively, the molding film 36 and the nonwoven 37 may be connected to each other along the entire length of the longitudinal side 45.

Absorbent core 34 may generally be any absorbent means that is compressible, comfortable, elastic, non-irritating to the wearer's skin, and capable of absorbing and retaining body secretions. Absorbent core 34 may be made 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 pulverized wood pulp (commonly referred to as airfelt), creped cellulose filler, modified crosslinked cellulose fiber [Young et al. On June 8, 1993]. Fibers as described in US Pat. No. 5,217,445], capillary channel fibers (ie, fibers with internal fiber capillary channels as described in US Pat. No. 5,200,248 to April 6, 1993), Absorbent foam (as described in U.S. Patent No. 5,260,345 to Desmaraes et al. On Nov. 9, 1993; and U.S. Patent No. 5,268,244 to Desmarais et al. On December 7, 1993), thermal Bonded air lamination materials (as described in US Pat. No. 5,607,414 to Richards et al. On March 4, 1997), hydrogel-forming polymer gelling agents [June 16, 1987] Materials as described in US Pat. No. 4,673,402 to Weisman et al. And US Pat. No. 4,935,022 to Lash et al. June 19, 1990], absorbent sponges, synthetic staples ( staple fibers, polymeric fibers, peat moss or any equivalent material or combination of these materials. Suitable absorbent cores including foams are described in U.S. Patent Nos. 5,260,345 to Desmaraes et al. US Patent No. 5,147,345 to Young et al. On September 15, 1992; US Patent No. 5,1949,720 to Desmaraes et al. On September 22, 1992; US Patent No. 5,198,472 to Desmaraes et al. On March 30, 1993; And US Pat. No. 5,250,576 to Desmaraes et al., Dated October 5, 1993. Further cores comprising foams are described in European Patent Application Publication No. 0 293 208 B1. Absorbent cores comprising sponges are described in US Pat. Nos. 3,512,530 and 3,954,493, and French Pat. No. 2,203,827.

The material selected for use as the absorbent core 34 is preferably flexible, soft, comfortable, compressible and elastic in order to enhance the body fit and comfort of the first absorbent member 30. Preferably, the absorbent core 34 is compressible such that the first absorbent member 30 deforms under a relatively small force experienced during normal use. In addition to being compressible, the material comprising the absorbent core 34 may preferably be comfortable so that the first absorbent member 30 can provide improved conformity to and around the labia and perineum. The first absorbent member 30 is generally compressible and compliant under a relatively small force exerted by the vulva during use, but is sufficiently burnt so as not to collapse continuously when the first absorbent member 30 is subjected to a normal wearing force. Sexuality is also important. Preferably, the first absorbent member 30 will be sufficiently elastic to conform to the curve of the body to provide close contact with the exposed vulva. The close contact with the exposed vulva allows the fluid to be better transferred from the user to the first absorbent member without causing the fluid to pass through and / or deviate from the first absorbent member. The elastic characteristics of the absorbent core 34 allow for improved registration, but must be balanced against the need for a soft and comfortable product for the wearer.

In a preferred aspect of the invention, the absorbent core 34 comprises hydrogel forming polymers and hydrophilic fibers such as air felt. Preferably, the absorbent core 34 comprises 10% to 60% hydrogel forming polymer. More preferably, the absorbent core 34 comprises 15% to 50% hydrogel forming polymer. Absorbent core 34 may comprise between 40% and 90% air felt. Desirably, the absorbent core 34 may comprise between 50% and 85% air felt. If desired, the absorbent core 34 may further include hydrophobic fibers. As shown in FIG. 3, the absorbent core 34 is generally manufactured in a cylindrical shape to provide a first absorbing member 30 having a generally cylindrical shape. The absorbent core 34 shown in FIG. 3 generally has a circular cross section, but the absorbent core may be manufactured in a wide variety of shapes such as rectangular, triangular, oval, square, pentagonal, U-shaped, Z-shaped, folded, and the like. .

Top sheet 32 may surround absorbent core 34 as shown in FIGS. 2 and 3. The top sheet 32 has a longer length and wider width than the absorbent core 34 (shown in FIG. 5). The transverse width of the top sheet 32 is greater than twice the transverse width of the absorbent core 34. This allows the longitudinal side 45 of the top sheet 32 to overlap the underside of the absorbent core 34 to enclose the absorbent core 34 as shown in FIG. 3. The longitudinal side of the top sheet 32 may be secured by any suitable way to maintain the surrounding shape. Suitable modes include, but are not limited to, adhesives such as line adhesives, spiral adhesives or point adhesives. In a preferred embodiment as shown in FIGS. 3 and 5, the line adhesive 51 is applied to one of the longitudinal sides 45 of the top sheet 32 along the entire length of the longitudinal length. Alternatively, dashed adhesive can be applied along the entire length of the longitudinal length.

Top sheet 32 may be coupled with absorbent core 34 in any suitable manner. Suitable modes include, but are not limited to, bonding the top sheet 32 and the absorbent core 34 with an adhesive such as spray adhesive, line adhesive or point adhesive between the top sheet 32 and the absorbent core 34. . Alternatively, or in addition, the top sheet 32 may entangle the fibers of the absorbent core 34 with the top sheet 32, or may separate the top sheet 32 with a plurality of separate individual bonding bonds. Or may be combined with the absorbent core 34 by any method known in the art. In order to ensure proper fluid transfer between the top sheet 32 and the absorbent core 34, it is desirable that the top sheet 32 is substantially continuously secured to the underlying absorbent core 34 over its usual bonding or contact surface. desirable. By substantially continuous fixing the top sheet 32 to the underlying absorbent core 34, the top sheet 32 will be less prone to detachment from the absorbent core 34 during use. Separation of the absorbent core from the top sheet 32 may impede fluid transfer from the top sheet 32 to the underlying absorbent core 34. As a result, the body facing surface of the absorbent core 34 can be secured to the top sheet 32 by an adhesive, while the body facing surface of the absorbent core 34 is the second absorbent member 50 from the absorbent core 34. It may not stick to the top sheet 32 to delay fluid transfer to the furnace.

The first absorbent member 30 is preferably circular or elliptical in cross section under its uncompressed condition, but may generally have any cross-sectional shape. The length PL, width PW and thickness PT of the absorbent member 30 can be any convenient dimension. The length PL is preferably about 2 to 35 cm, more preferably about 10 to 35 cm and most preferably about 20 to 35 cm. Preferably, the length PL of the first absorbing member 30 may be generally the same as the length SL of the second absorbing member 50. The width PW is preferably about 0.5 to 5 cm, more preferably about 1 to about 5 cm, most preferably about 2 to about 4 cm. The width PW of the first absorbing member 30 may be smaller than the width SW of the second absorbing member 50. The thickness PT is preferably about 0.2 to about 2.0 cm, more preferably about 0.2 to 1.5 cm, most preferably about 0.4 to 1.2 cm. Preferably, the thickness PT of the first absorbing member 30 may be thicker than the thickness ST of the second absorbing member 50. The ratio of thickness PT to width PW (or PT / PW) may be 0.05 to 1.5. Preferably, the ratio of the thickness PT to the width PW may be 0.08 to 1.00. More preferably, the ratio of thickness PT to width PW may be 0.08 to 0.5.

The caliper of the first absorbing member 30 is determined by the following test. A comparator and especially Peacock Gage Model No. 307, available from Ozaki Manufacturing Co., LTD., Are required. The comparator shall be made of aluminum and have a circular comparator foot having a weight of 9.0 g and a contact surface of 16 cm ² . The comparator is zeroed. A 60.0 g stainless steel weight is placed on an extended axis past the comparator dial. The comparator foot is raised and the first absorbent member is placed on the substrate with the garment surface facing down. The first absorbent member is positioned on the substrate so that the foot rests on the portion of the first absorbent member to be measured when the foot is lowered. Efforts are made to flatten the first absorbent member or to prevent any wrinkles. Gently lower the foot to the first absorbent member. The first absorbent member caliper is determined by reading the comparator scale 5-10 seconds after the foot begins to contact the first absorbent member.

The first absorbent member 30 of the present invention is preferably relatively compliant. The first absorbent member is preferably kept relatively compliant so that it easily fits into the labia groove during use. It has been found that the first absorbent member having a width and / or a thickness can be comfortably matched next to the labia area. The first absorbing member is described above as having a larger width or thickness than the above width or thickness, but they can also be matched in the labia groove if sufficiently compatible. All of the first absorbent members must be matched in the labia groove, but preferably a portion of the first absorbent member can be matched in the labia groove.

The first absorbent member 30 may comprise an optional element. The first absorbent member 30 can optionally include an elastic member with the absorbent core 34. The elastic member may comprise a single member or a plurality of individual members. Materials suitable for use as elastic members include, but are not limited to, nylon, polypropylene, polyurethane, polyethylene, polyester synthetic rubber, and other synthetic materials such as molded films, or natural materials such as rubber, sponges, or the like. Any suitable material that can resist collapse under normal wearing conditions of the sanitary napkin during use. The elastic member can be manufactured in a wide variety of shapes such as rectangular, triangular, oval, square, pentagonal, U-shaped, Z-shaped folded and the like. The elastic member may extend through the entire length 30 of the first absorbent member 30. The elastic member may only extend through a portion of the length of the first absorbent member 30. The elastic member may be located within the first distal end 27, the central portion 28, the second distal end 29, or any combination thereof. For example, the elastic member may be formed at one of the first end portion 27 or the second end portion 29 of the first absorbent member, and the first end portion 27 or the first end portion of the first absorbent member 30 may be formed. Both end portions 29 may be located at the central portion 28 of the first absorbent member 30 or at the central portion 28 and the distal portions 27 and 29 of the first absorbent member 30.

Optionally, the first absorbent member 30 may include a capture layer positioned between the top sheet 32 and the absorbent core 34. The capture layer can provide a variety of actions, including improving the uptake of secretions over the absorbent core 34 and into the absorbent core 34. By improving the uptake of secretions, the capture layer provides a more even distribution of secretions over the entire absorbent core. The trapping layer may comprise synthetic fibers, including polyester, polypropylene or polyethylene; Natural fibers including cotton or cellulose; Or any of a variety of different materials, including nonwoven or woven webs of any equivalent material or mixture of materials. Examples of sanitary napkins having a capture layer and a top sheet are described in more detail in US Pat. No. 4,950,264 to Osborne and PCT Publication No. WO 93/11725, published in the name of Cree et al. On June 24, 1993. It is described. Each of which is incorporated herein by reference. In a preferred embodiment, the capture layer can be connected by any conventional method of joining the webs together, most preferably by a bonding bond as described in more detail in the application of Cree referenced above.

In FIGS. 1-3A, the 2nd essential component of the composite sanitary napkin 20 of this invention is the 2nd absorbing member 50 (base member). The second absorbent member 50 generally has a rectangular shape extending longitudinally along the longitudinal center line L. As shown in FIG. In a preferred aspect, the longitudinal length SL may generally be equal to the longitudinal length PL of the first absorbent member 30. The transverse width TW may generally be wider than the transverse width PW of the first absorbent member 30. The second absorbent member 50 has a longitudinal side 21 and a lateral side 22. In the preferred aspect shown in FIG. 1, the pair of flaps 33 extend outward from the longitudinal side 21 at the central portion 28. The second absorbent member 50 is preferably a fluid permeable body facing sheet or fluid permeable top sheet 52, a fluid impermeable garment facing sheet or fluid impermeable back sheet 54 connected with the top sheet 52, And a second absorbent element 56 positioned between the top sheet 52 and the back sheet 54.

Top sheet 52 may be any fluid permeable material commonly used in sanitary napkins, disposable diapers, and the like. The top sheet 52 may be any of the materials described above as useful for the top sheet 32 of the first absorbent member 30. Preferred top sheet 52 comprises a perforated film. Perforated molded films are permeable to the topsheet because they are permeable to body secretions but are nonabsorbent and have a reduced tendency for fluid to return to the wearer's skin or to rewet the wearer's skin. Thus, the surface of the molded film in contact with the body is kept dry, reducing body contamination and creating a more comfortable feel for the wearer. Suitable molded films are described in US Pat. No. 3,929,135 to Thomson, Dec. 30, 1975; U.S. Patent No. 4,324,246, issued to Mullan et al. On April 13, 1982; US Patent No. 4,342,314 to Radel et al. On August 3, 1982; US Patent No. 4,463,045, issued to Al et al. On July 31, 1984; And US Pat. No. 5,006,394 to Baird, dated April 9, 1991. Each of these patents is incorporated herein by reference. Preferred topsheets for the second absorbent member of the present invention are molded films described in one or more of the above patents and sold under the trade name "Dryweave" by The Procter & Gamble Company, Cincinnati, Ohio.

Absorbent element 56 may be any absorbent material conventionally used for sanitary napkins, disposable diapers, and the like. It may be any of the materials described above as useful for the absorbent core 34 of the first absorbent member 30. As a practical matter, most of the body fluid is absorbed and retained by the absorbent core 34 of the first absorbent member 30. One major action of the second absorbent member 50 is to prevent the user's garment from being soiled by the absorbed fluid which may be released from the first absorbent member or may accidentally pass over the first absorbent member. will be. The total absorbent capacity of the absorbent element 56 may in turn be somewhat less than the absorbent capacity of the absorbent core 34. Since the absorbent core 34 is preferably adapted to absorb most or substantially all body fluids during use, its absorbent capacity will be slightly greater but less significant than the absorbent element 56. Since the absorbent element 56 of the second absorbent member 50 performs a different function than the absorbent core 34, the absorbent element 56 can be somewhat thinner and smaller in volume than the absorbent core 34, and most Preferably it is somewhat thinner and smaller in volume than the absorbent core 34.

Since the absorbent element 56 has different requirements compared to the absorbent core 34, it can be formed of different materials. For example, single or multi-ply paper tissues commonly used in paper towels or toilet tissues may be used to form the absorbent element 56. Preferably, the absorbent element 56 is formed from about 1 to about 5 ply paper tissue. From about 24 to about 48 g per 1 m ² , as prepared by the method described in US Pat.

The back sheet 54 is preferably made from a thin plastic film, although it is impermeable to liquids (eg, menstrual blood and / or urine), and other flexible fluid impermeable materials may also be used. As used herein, the term "flexible" refers to a material that is flexible and easily adapts to the general shape and curve of the body. In use, the back sheet 54 is sandwiched between the absorbent element 56 and the undergarment of the user. The function of the back sheet 54 is that the secretion that is released from or absorbed by the absorbent element 56 and that is released from the first absorbent element 30 or may accidentally pass through the first absorbent element 30 is reduced by the user's underneath. To prevent contact and contamination of the cement. Accordingly, the back sheet 54 may comprise a combination material such as a woven or nonwoven fabric, a polymeric film such as a thermoplastic film of polyethylene or polypropylene, or a film-coated nonwoven fabric. Preferably, the back sheet is a polyethylene film having a thickness of about 0.012 mm (0.5 mil) to about 0.015 mm (2.0 mil). Exemplary polyethylene films are manufactured under the name P18-0401 by Clopay Corporation, Cincinnati, OH, and by the Ethyl Corporation, Visqueen Division, TERHOTE, IN, USA. Manufactured under the name XP-39385. The back sheet is preferably embossed and / or matte finished to provide a more textile-like appearance. In addition, the back sheet may allow vapor to escape from the absorbent element 56 (ie, ventable), but prevents secretions from passing through the back sheet 54.

The shape of the second absorbent member 50 can generally be a rectangle surrounded by the longitudinal side 21 and the transverse end 22. Other suitable shapes include, but are not limited to, oval, hourglass, dog bone, asymmetric, and the like. The second absorbent member 50 may extend laterally from the longitudinal side 21 of the second absorbent member 50 at the central portion 28 as shown in FIG. 1 and may each have adjacent flaps 33. have. The flap 33 is shaped to be positioned between the edge of the wearer's panties and the thighs of the wearer and span the edge of the wearer's panties at the crotch region. Flap 33 serves two or more purposes.

Secondly, the flap 33 is preferably provided by an attachment means as described herein on its garment facing surface so that it can be folded back below the panty and attached to the garment facing surface of the panty.

In a preferred aspect, the flap 33 consists of a top sheet and a back sheet. In addition, the flap 33 is preferably integral with the thin layer of the second absorbent element 50. In other words, the top sheet 52 of the second absorbent member 50 and the back sheet 54 of the second absorbent member are simply laterally outward from the longitudinal side 21 to form the flap 33. Can be extended. However, the flap 33 need not be integral with the second absorbent member 50 and may be a separate element attached to the second absorbent member 50. In addition, the flap 33 can be constructed in a single substrate or other thin layer form. However, the flap 33 preferably has a back sheet to prevent the discharge leading to the flap from contaminating the edges of the wearer's panties.

In addition, the flap 33 may be provided with an absorbent member to at least a point beyond the edge of the wearer's panties. In theory, only a relatively small amount of menstrual blood should reach the flap 33 and eventually only a relatively small amount of absorbent material is desirable for the flap. However, the flap 33 preferably has at least some absorbent material to prevent any secretions leading to the flap 33 from flowing into areas that are not protected further. The absorbent material can be an extension of the tissue or absorbent element 56. Preferably, the absorbent material in the flap 33 is relatively very flexible.

Examples of suitable release papers include, but are not limited to, BL30MG-A Silox E1 / 10 and BL30MG-A Silox 4P / 0 manufactured by Akrosil Corporation, Menasha, Wisconsin. The composite sanitary napkin 20 of the present invention is used by removing the release paper 59 and 63, and then placing the sanitary napkin 20 in the panty so that the adhesives 58 and 62 contact the panty. Adhesives 58 and 62 hold sanitary napkins in place within panties during use.

The top sheet 52 and back sheet 54 of the second absorbent member 50 may be connected to each other by any suitable manner. The top sheet 52 may be connected to the back sheet 54 along the periphery 64 or may be connected to the back sheet at all sites except where the absorbent element 56 is present. At the site where the absorbent element 56 is present, the top sheet 52 and the backsheet 54 may each be connected to the absorbent element 56. Suitable modes include, but are not limited to, applying pressure, heat, heat and pressure, or adhesives such as line adhesives, spiral adhesives, or point adhesives. In the preferred embodiment shown in FIG. 1, the top sheet 52 and the back sheet 54 can be connected by applying heat along the perimeter 64 of the sanitary napkin 20.

The length SL, the width SW and the thickness ST of the second absorbing member 50 can be any convenient dimension. The length SL is preferably about 5 to 35 cm, more preferably about 10 to 35 cm and most preferably about 20 to 35 cm. Preferably, the length SL of the second absorbent member 50 may be generally equal to the length PL of the first absorbent member 30. The width SW is preferably about 4 to 13 cm, more preferably about 5 to about 11 cm, most preferably about 6 to about 9 cm.

The thickness ST is preferably about 0.1 to 2.0 cm, more preferably about 0.1 to about 1.0 cm, most preferably about 0.1 to about 0.4 cm. Preferably, the thickness ST of the second absorbing member 50 may be thinner than the thickness PT of the first absorbing member 30.

The second absorbent member (base member) 50 may optionally be manufactured without the absorbent element 56. Since most, if not all, of body fluids are preferably absorbed and retained by the absorbent core 34 of the first absorbent member 30, the foundation member 50 merely carries the user's undergarment to the first absorbent member. It is necessary to protect it from contamination by a relatively small amount of fluid which may be released from 30 or may accidentally pass over absorbent member 30. Thus, because there is a relatively small amount of fluid that may come into contact with the base member, there may be no need for a foundation element to retain the fluid in the base member 50 and to prevent contamination of the user's garment.

In order to form the composite sanitary napkin 20 of the present invention, the first absorbent member 30 and the second absorbent member 50 are connected means generally shown at 70 in FIGS. 1 to 3, 6 and 7. Is connected by. The connecting means 70 has a sufficient adhesive force in which the first absorbent member 30 and the second absorbent member 50 do not separate during use, and have the first absorbent member 30 in the composite sanitary napkin 20 of the present invention. And a function of connecting the second absorbing member 50. Any suitable connection means can be used, such as adhesive attachment, pressure attachment, thermal attachment, or ultrasonic attachment. The first absorbent member 30 may be attached to the second absorbent member 50 by connecting means 70 along the entire conventional length. Alternatively, the first absorbent member 30 may be attached to the second absorbent member 50 intermittently along the usual length.

In the preferred embodiment shown in FIGS. 1-3, 6 and 7, the first absorbent member 30 comprises a connecting means 70, including a first connecting means 72 and a second connecting means 74. By the second absorbing member 50.

The first connecting means 72 comprises applying pressure to the overlapping transverse ends 22 and 25 in a plurality of separate dots. By applying pressure to the overlapped transverse ends 22 and 25, the top sheet 32 of the first absorbing member 30 and the top sheet 52 and the back sheet 54 of the second absorbing member 50 are formed. Are attached to the transverse ends 22 and 25 overlapping one another. Alternatively, the first connecting means 72 may comprise applying heat to a plurality of separate points, lines or areas. Although thermal work is applied to connect the mullet-layer well, the heat transfer between layers to connect the layers may worsen as the layer becomes thicker. In the preferred embodiment shown in FIG. 2, the three sides of the top sheet 32 are formed because the longitudinal side portions 45 of the top sheet 32 of the first absorbent member 30 overlap each other under the absorbent core 34. Five layers are connected, including one layer of top sheet 52 and one layer of back sheet 54. If the top sheet 32 comprises two layers with the molding film 36 and the nonwoven 37, the eight layers may be connected to each other as shown in FIG. 7. Once the layer is thick, it is desirable to apply pressure, or pressure and heat, to connect the layers. Alternatively, the first connecting means 72 may comprise applying an adhesive between the layers or applying a combination of pressure, heat and adhesive. In a preferred embodiment, the adhesive 72A may be applied to the inner surface of the top sheet 32 at the transverse ends 46 as shown in FIGS. 2, 5, and 7. Alternatively, adhesive 72B may be applied between molding film 36 and nonwoven 37 at transverse ends 44 and 48 as shown in FIG. Alternatively, both adhesives 72A and 72B can be applied.

The second connecting means 74 comprises applying an adhesive, such as a spiral adhesive, a line adhesive or a point adhesive between the first absorbent member 30 and the second absorbent member 50. As shown in FIG. 6, in a preferred embodiment, the spiral adhesive 74 is applied continuously between the first absorbent member 30 and the second absorbent member 50 as the second connecting means. If the first absorbent member 30 and the second absorbent member 50 are required to be attached to each other along the entire normal length, applying a spiral adhesive may indicate that the absorbent members 30 and 50 are intermittently attached. It is preferable to use a spiral adhesive because it prevents. The first absorbing member 30 and the second absorbing member 50 are preferably attached with a narrower width AW than the lateral width PW of the first absorbing member 30. Preferably, the width AW is less than 70% relative to the width PW. This allows the first absorbent member 30 to conform well to the female body shape and the movement of the female body.

Composite sanitary napkin 20 may include various substitutes and / or optionals. The first absorbent member 30 may include a fluid barrier wall 35 as shown in FIG. The fluid barrier wall 35 may be positioned midway from the base of the absorbent core 34 to inhibit fluid from moving in the absorbent core towards the second absorbent element 50. The fluid barrier wall 35 tends to retain the absorbed fluid in the absorbent core 34 and is constructed from a material having the same properties as the fluid impermeable back sheet of the second absorbent member 50 as described herein. Can be. The fluid barrier wall 35 may extend along the entire length of the first absorbent member 30 or may include a central portion 28 or a first end portion 27 and a second end portion of the first absorbent member 30. 29).

Alternatively, the top sheet 32 of the first absorbent member 30 may include a sheet having a fluid permeable zone 76 and a fluid impermeable zone 78. If the top sheet 32 comprises a molded film, the fluid permeable zone 76 may be a perforated zone and the fluid impermeable zone 78 may be a non-perforated zone. As shown in FIG. 9, the fluid permeable zone 76 of the top sheet 32 is intermediate at the top of the absorbent core 34 to inhibit fluid from moving from the absorbent core toward the second absorbent member 50. Can be located up to. Fluid permeable zone 76 tends to retain the absorbed fluid in absorbent core 34.

The composite sanitary napkin 20 can be extended. The individual components of the first absorbent member 30 and the second absorbent member 50 are configurations which can extend in the longitudinal direction (preferably stretchable), especially when the composite sanitary napkin 20 is worn. It may consist of elements. Preferably, the composite sanitary napkin 20 can be stretched longitudinally between about 15% and about 40% of the unstretched length. This extensibility provides better use, comfort, and reduced contamination when the composite sanitary napkin is attached to the wearer's undergarment. Preferably, the second absorbent member 50 is composed of components that can also extend laterally when the composite sanitary napkin 20 is worn. Desirably, the composite sanitary napkin 20 can be stretched laterally between about 15% and about 40% of the unstretched length. The top sheet 32 for both the first absorbent member 30 and the second absorbent member 50 was issued to Curro et al. On November 22, 1994, which is incorporated herein by reference. Elastic, three-dimensional, fluid permeable polymeric webs as disclosed in US Pat. No. 5,366,782. A particularly preferred extensible back sheet is an extended adhesive film known as Formula # 198-388, manufactured by Findley Adhesives Company, Wawawatosa, Wisconsin. Sanitary napkins with extensible components are disclosed in US Pat. No. 5,611,790 to Osborne et al. On March 18, 1997 and PCT Publication No. WO 93/01786 published on February 4, 1993 in the name of Osborne et al. It is described. The disclosure of this publication is incorporated herein by reference.

The composite sanitary napkin 20 can be adapted to the female body. Since the first absorbent member 30 is preferably dimensioned and shaped to match near the labia area, the first absorbent member 30 will be at least partially present within the labia. As shown in FIG. 10, when the composite sanitary napkin 20 is worn by a woman and supported by an undergarment 82, a portion of the first absorbent member 30 is preferably near the labia area during use. Will be matched. In contrast, one primary function of the second absorbent member 50 is that absorbed, in which the user's garment may be released from the first absorbent member 30 or may accidentally pass over the first absorbent member 30. It is to prevent contamination by the fluid. The second absorbent member is preferably removed from the body so as not to contact the body. The shape of the first absorbent member 30 is dimensioned and shaped such that the second absorbent member 50 is separated from the body and secures a space 80 between the body and the second absorbent member 50. This may leave the longitudinal side of the second absorbent member 50 unpolluted.

The composite sanitary napkin 20 may absorb body fluids. The total absorbent capacity of the first absorbent member 30 should be compatible with the intended secretion load on the composite sanitary napkin 20. In addition, the absorbent capacity of the absorbent member 30 can be varied to accommodate the wearer in the range of anticipated secretions. Typically, 2-20 g of secretion is expected during the normal time of wearing a sanitary napkin. When the composite sanitary napkin 20 is exposed to 2 to 20 g of the fluid load, the first absorbent member 30 can absorb 80% of 2 to 20 g in actual wearing situations. In addition, when the composite sanitary napkin 20 is exposed to a fluid load of 20-30 g in excess of the normal amount, the first absorbent member 30 may absorb 70% of 20-30 g of fluid. Since the first absorbent member 30 has an absorbent capacity of at least 70% of the loaded fluid of 2 to 30 g when the sanitary napkin is applied and used on the female body, the first absorbent member 30 having the above capacity is The longitudinal side of the second absorbent member 50 is left intact. This provides a visual cue to increase consumer confidence in the absorbent and leak resistant performance of sanitary napkin products.

The first absorbent member 30 preferably comprises a hydrogel forming polymer for enhancing the absorbent capacity of the first absorbent member 30. As the first absorbent member contains more hydrogel forming polymer, the first absorbent member 30 has a larger absorbent capacity. Since the hydrogel forming polymer swells after the polymer absorbs the fluid, the first absorbent member 30 extends in the transverse direction and the thickness direction. This extension of the first absorbent member provides greater compliance and conformity between the first absorbent member 30 and the female body. However, too many hydrogel forming polymers cause gel-blocking problems, resulting in reduced absorption capacity. More importantly, too much hydrogel forming polymer, when absorbing fluid, makes the first absorbent member 30 into a cylindrical shape that is not easily bent without high bending forces. In this case, since the transverse end of the composite sanitary napkin 20 tends to fall away from the body, the first absorbent member 30 may not fit the curved shape of the female body. Consequently, suitable amounts of hydrogel forming polymers are preferred in view of the standard of absorbency, compliance, and conformability of composite sanitary napkins having a first absorbent member.

It may be desirable to provide a composite sanitary napkin having a first absorbent member with varying width or degree of caliper over its length. For example, the first absorbent member may be relatively thicker at the center as opposed to the distal end. Alternatively, the first absorbent member may be relatively thinner at the center as opposed to the distal end.

While certain aspects of the invention have been illustrated and described, it will be apparent to those skilled in the art that various other changes and modifications can be made without departing from the spirit and scope of the invention. As a result, the appended claims cover all such variations and modifications as fall within the scope of the present invention.
