DETAILED DESCRIPTION

In 1 is an absorbent article 10 shown near the crotch of a human body 12 is arranged. The absorbent article 10 may be a sanitary pad, a menstrual pad, a sanitary napkin, a panty liner, a pant pocket, an incontinence garment, or other type of absorbent product. For purposes of explanation, the absorbent article will be discussed 10 described as a hygiene insert. The hygiene insert 10 is designed to be worn by women to absorb excreted body fluid, especially menstrual fluid and urine. In 1 is a side view of a human body 12 shown a hull 14 with a waist 16 and a crotch area 18 includes, which is arranged at a lower end of the fuselage. A pair of legs 20 one of which is shown extends from the crotch area 18 downward. The absorbent article 10 gets close to the pudendum or vulva area of a woman through a lingerie 22 held. The underwear 22 is typically a pair of underpants with a waist opening, two leg openings and a crotch area located between the two leg openings. The crotch area has edges or seams 24 which are arranged on opposite sides of the crotch area. The edges or seams 24 extend around the leg openings around. Part of the edges or seams 24 usually touches the groin of the wearer when the underwear 22 over the hull 24 pulled and around the waist 16 is arranged. The on the edges or the seams 24 the underwear 22 in the step area 18 Acting forces cause an upward force on the edges or seams 24 with the body of the wearer in contact.

According to 2 includes the hygiene insert 10 a first groove or channel 26 and a second groove or channel 28 each formed in a lower surface thereof. The two edges 24 the leg openings of the underwear 22 are designed to each in the first and second channels 26 and 28 enter and / or engage with them. The hygiene insert 10 also has a first end 30 that is adjacent to a front part of the insert 10 is arranged, and an opposite or back end 32 which is adjacent to a rear portion of the insert 10 is arranged. The first and second ends 30 and 32 are each equidistant from a midpoint 34 the hygiene insert 10 arranged. The middle-point 34 is at the intersection of an oblong central axis xx and a vertical center axis zz arranged. The grooves or channels 26 and 28 may be shifted relative to the center as needed.

It is worth noting that during the application the hygiene insert 10 along the vertical central axis z ₁ -z ₁ of in 1 or may be centered in front of or behind the vertical central axis z ₁ -z _{1 of} the body depending on the particular preference of the wearer. It should also be mentioned that the hygiene insert 10 although these are considered symmetrical with respect to each of the first and second ends 30 and 32 is shown, and this equidistant from the center 34 spaced as a non-symmetrical hygiene liner may be formed, which varies in shape from one end to the other.

In 3 becomes the hygiene insert 10 shown in more detail. The hygiene insert 10 includes a liquid-permeable cover 36 and a liquid-impermeable shield 38 that work together to form an absorbent element 40 to enclose. The cover 36 may be constructed of a natural or synthetic material, and body fluids such as menstrual fluid, blood, urine, etc. should be able to easily penetrate. To suitable materials for the cover 36 include materials that have a soft touch, such as a polyolefin spunbond that is manufactured and sold by Kimberly-Clark Corporation. The cover 36 could also be made from a composite fabric, polyester, polypropylene, polyethylene, nylon or similar fiber types. Other polyolefins such as linear low density polypropylene, linear low density polyethylene, finely perforated laminate, and mesh materials may also be used. When a thermoplastic film is used, it is necessary to perforate, perforate or slit it to make it liquid permeable.

The liquid-impermeable shield 38 is designed to prevent the passage of liquid from the hygiene liner 10 to prevent. The shield 38 however, it may be constructed to prevent the passage of air and moisture vapor from the sanitary pad 10 to permit or permit while it serves to prevent the passage of fluids or liquids. The shield 38 could also be an air-permeable microporous film that prevents penetration of liquids. The shield 38 For example, a foam may be a polyolefin foam or a polyurethane foam. A polyolefin foam can be made of polyethylene or polypropylene. The shield 38 may also be constructed as a liquid pervious foam which has been treated or coated to be liquid impermeable. Preferably, the shield is 38 composed of a very thin thermoplastic film having a thickness of less than about 2 millimeters (mm) and preferably less than about 1 mm. Two well-functioning thermoplastic films are polyethylene and polypropylene. The films can be dyed or made of a special color such as pink or peach to the hygiene insert 10 more attractive.

Still related to 3 you will realize that the cover 36 and the shield 38 so connected or sealed to each other to an edge seal 42 to build. This edge seal 42 extends completely around the absorption element 40 and encloses the absorbent element 40 , If desired, something can be formed, known as a wrapped upholstery, with the shielding 38 near a lower surface of the absorbent member 40 is arranged and the cover 36 completely around both the absorption element 40 as well as the shielding 38 is winding. The cover 36 is then along a lower surface of the hygiene insert 10 attached to itself or attached to itself. Those skilled in the art will recognize various other ways of assembling the cover, the absorbent member, and the shield, and various alternatives may be used for this invention.

The absorption element 40 is between the cover 36 and the shield 38 arranged. The absorption element 40 has a first longitudinally extending side 44 and a second longitudinally extending side 46 , The absorption element 40 also has a first end 48 and a second end 50 , in the 2 are shown as dotted lines. The absorption element also has a body-facing surface 52 and a laundry facing surface 54 , The body-facing surface 52 points to the body of the wearer of the hygiene insert 10 although not necessarily in contact with the body, although this may be the case. The body-facing surface 52 of the absorption element 40 is usually from the cover 36 covered. The laundry facing surface 54 of the absorption element 40 points to underwear 22 but not necessarily with underwear 22 in touch. The laundry facing surface 54 is usually from the shield 38 covered, although this is not the case.

To explain, the absorption element 40 merely described as a single absorption layer. However, it should be kept in mind that the absorption element 40 from one or more Absorbent layers or a combination of one or more layers can be constructed with interposed superabsorbent material. The absorption element 40 may be made of natural or synthetic fibers or a compound thereof. The natural fibers include cellulosic fibers such as shredded wood, cotton or processed cellulose. Synthetic fibers include polyesters or polyolefins, with polyethylene or polypropylene fibers being preferred. The absorption element 40 may also be made of a compound that is a compound of shredded wood and synthetic meltblown fibers. When synthetic fibers are used, the fibers can be treated with a surface reaction agent to increase their wettability.

The absorption element 40 may also contain a hydrocolloidal material, commonly referred to as a superabsorbent. Superabsorbents are usually added to absorbent elements to increase the amount of liquid that the absorbent element can contain, and also to increase the ability of the liquid retention. The superabsorbent may be added as a single particle or it may be formed as a laminar structure on a support layer with an incorporated superabsorbent material.

In reference to 3 you will still recognize that the first and second grooves or channels 26 and 28 each in a lower surface of the absorption element 40 are formed, and the shield 38 the contours of each first and second channels 26 and 28 consequences. This construction allows the first and second channels 26 and 28 each visible in the final product. It is also possible to use the first and second channels 26 and 28 each in the lower surface of the hygiene insert 10 train and then the shield 38 over the channels 26 and 28 to stretch or bridge them. When this has been done, the shield runs 38 not along the contour of the channels 26 and 28 , The intervention of the edges or seams 24 the underwear 22 causes the shielding 38 stretches and that each upward in the first and second channels 26 and 28 is forced. Preferably, the shield 38 so formed that these each in the first and second channels 26 and 28 penetrates, and the first and second channels 26 and 28 are visible to the end user when the hygiene insert 10 ready for the application. In particular, for hygiene deposits, it is common practice that each deposit is wrapped in its own wrapper to keep it clean and hygienic. The wrapper may be made of a thermoplastic material such as polyethylene or polypropylene.

In the 4 - 8th Several embodiments are shown, the different arrangements, sizes and configurations of each of the first and second channels 26 and 28 represent. For the sake of simplicity, only the absorption layer is 40 shown, wherein the first and second grooves or channels 26 and 28 each in the laundry facing surface 54 are formed. By way of illustration, the longitudinally extending sides will be used respectively 44 and 46 and respectively for the body facing and garment facing surfaces 52 and 54 of the absorption element 40 in the 4 - 8th the moving reference numerals used. The only difference is in the reference numerals used to denote the channels.

In 4 contains the absorption element 40 a first groove or a first channel 26 ' and a second groove or channel 28 ' , Each of the first and second channels 26 ' and 28 ' each contains a vertical sidewall 56 , a horizontal base 58 and a tapered sidewall 60 , Each of the tapered sidewalls 60 extends from the horizontal base 58 to the laundry facing surface 54 , The tapered sidewalls 60 are aligned next to the elongated central axis xx, while the vertical sidewalls 56 outside of and adjacent to the respective first and second long sides 44 and 46 are arranged. The two channels 26 ' and 28 ' are spaced apart and each is disposed on an opposite side of the elongated central axis xx. The first and second channels 26 ' and 28 ' can each be straight or not straight. Preferably, the first and second channels are 26 ' and 28 ' are each aligned parallel to each other or are mirror images of each other when they are not straight with respect to the elongated central axis xx. The depth (d) of each of the first and second channels 26 ' and 28 ' may vary but is at least about 0.1 inch (about 2.5 mm) and is best about 0.1 inch to 0.5 inch (about 2.5 mm to about 13 mm). Since the thickness (t) of the absorbent element 40 along the elongated central axis xx, another possibility is the depth (d) of each of the first and second channels 26 ' and 28 ' indicate that the depth (d) of the channel 26 ' and 28 ' ranging from about 10 percent to about 90 percent of the thickness (t) of the absorbent element 40 can lie. Preferably, the depth (d) ranges from about 10 percent to about 75 percent of the thickness (t) of the absorbent member 40 , The best is the depth (d) of the channels 26 ' and 28 ' in the range of about 20 percent to about 50 percent of the thickness (d) of the absorbent element 40 , Preferably, the depth (d) of the channels is 26 ' and 28 ' ranging from about 25 percent to about 50 percent of the thickness (t) of the absorbent element 40 ,

It should be noted that if the absorp tion element 40 is composed of more than one layer, the depth of the respective first and second channel 26 ' and 28 ' a percentage of the thickness (t) of the absorbent element 40 will be at a certain position. It should also be noted that if the absorption element 40 is formed with an increase along the line of the elongated central axis xx or structured in any other way, the part of the absorption element 40 each with the first and second channel 26 ' and 28 ' of lesser thickness (t) than the maximum thickness of the absorbent element 40 can be.

It will now be related to 5 an alternative arrangement of the first and second channels shown. The absorption layer 40 contains a first groove or a channel 26 '' and a second groove or channel 28 '' , The first and second channels 26 '' and 28 '' are each in the form of an inverted semicircle having a radius "r 'of at least about 0.01 inch (about 0.25 mm), and preferably a radius" r "of about 0.01 inch to 0.25 inch (about 0 , 25 mm to 6.4 mm) The first and second channels 26 '' and 28 '' can each be straight or not straight. The first and second channels 26 '' and 28 '' extend along a second part of the part of the absorption element 40 or they extend over the entire length of the absorbent element 40 ,

According to 6 an even further arrangement of the first and second channels is shown. The thin absorption element 40 has first and second grooves or channels 26 ''' and 28 ''' each formed therein. The first and second channels 26 ''' and 28 ''' are each in the shape of an inverted Us, located in the absorption element 40 extends to a greater extent than that in 5 is shown. For example, the depth (d) of the first and second channels 26 ''' and 28 ''' each from about 50 percent to about 95 percent of the thickness (t) of the absorbent element 40 exhibit. Preferably, the depth (d) of the first and second channels 26 ''' and 28 ''' each between about 70 percent to about 95 percent of the thickness (t) of the absorbent element 40 and most preferably, the depth (d) of the first and second channels 26 ''' and 28 ''' each from about 75 percent to about 90 percent of the thickness (t) of the absorbent element 40 lie. The first and second channels 26 ''' and 28 ''' can each be straight or not straight. The first and second channels 26 ''' and 28 ''' can each be along a portion of the length of the absorbent element 40 extend or may extend along the entire length of the absorbent element 40 extend. The length of the first and second channels 26 ''' and 28 ''' each may be along a distance of about 25 percent to 100 percent of the length of the absorbent element 40 extend. Preferably, the length of the first and second channels 26 ''' and 28 ''' each at a distance of from about 25 percent to about 75 percent of the length of the absorbent element 40 and most preferably from about 30 percent to about 70 percent of the length of the absorbent member 40 extend. It should be noted that if a hygiene insert 10 an edge seal 42 possesses, the length over all or the total length of the hygiene insert 10 greater than the total length of the absorbent element 40 is.

In 7 is a thin absorption element 40 shown with a much larger overall width. In the laundry facing surface 54 of the absorption element 40 are a first groove or channel 27 and a second groove or channel 29 formed, both having an inverted V-shape arrangement. The depth of the V-shaped arrangement may be inwardly into the absorbent element from about 10 percent to about 90 percent of the total thickness (t) of the absorbent element 40 extend. Preferably, the V-shaped notch extends into the absorbent element 40 at an amount of between about 20 percent to about 75 percent of the total thickness (t) of the absorbent member 40 and most preferably from about 25 percent to about 50 percent of the thickness (t) of the absorbent member. The first and second channels 27 and 29 correspond in their function respectively to the channels 26 and 28 . 26 ' and 28 ' , and 26 '' and 28 '' , If the first and second channels 27 and 29 are straight, they can be inwardly at least about 0.25 inches (about 6.4 mm) from the first and second longitudinally extending sides 44 and 46 each be removed. Preferably, the first and second channels are 27 and 29 inwardly at least about 0.5 inches (about 13 mm) from the first and second longitudinally extending sides 44 and 46 each spaced. If the channels 26 and 28 not exactly the ends of each channel may be respectively to the first and second longitudinally extending sides 44 and 46 extend.

When comparing the 6 and 7 you realize that the channels 27 and 29 at a greater distance from the elongated central axis xx in 7 as in 6 are arranged. This size difference may be advantageous in adapting to different crotch areas of a woman, with the distance between the groin varying depending on the particular anatomy. For a consumer wearing a certain type of underwear, it may also be advantageous to wear an absorbent article so that the side edges 24 the underwear 22 easily in each of the first and second channels 27 and 29 fit.

In 8th is an embodiment of an absorbent element 40 shown, wherein the absorption element has a contoured surface, the along the elongated central axis xx is thicker and near the first and second longitudinally extending sides 44 and 46 each is thinner. In this embodiment, the first and second channels 27 ' and 29 ' each a similar arrangement as the respective in 4 shown first and second channels 26 ' and 28 ' , The first and second channels 27 ' and 29 ' however, are each in the thinner outer regions of the absorbent element 40 arranged. Again it can be seen that in 8th each of the first and second channels 27 ' and 29 ' at a greater distance from the elongated central axis xx than respectively the first and second channels 26 ' and 28 ' , in the 4 are shown are arranged. It is conceivable that the width of the hygiene insert 10 and the arrangement of each of the first and second channels 27 ' and 29 ' is sized so that the crotch area 18 the underwear 22 essentially does not have to be changed when the margins 24 the underwear 22 the hygiene insert 10 touch. Further, the first and second channels should be 27 ' and 29 ' each be arranged so that they the absorption element 40 forcibly contact the groin area of the user.

It should also be noted that the first and second channels 26 and 28 . 26 ' and 28 ' . 26 '' and 28 '' . 26 ''' and 28 ''' . 27 and 29 such as 27 ' and 29 ' in a number of different ways in the lower surface 54 of the absorption element 40 can be formed. The channels may be cut into the absorbent element using a knife or a rotary cutter, or they may be stamped into the absorbent element. The channels may also be formed by other means known to those skilled in the art. Forming the channels by imprinting may be the easiest to do. The melting process is advantageous in that the channels can be formed simultaneously.

In 9 is the hygiene insert 10 adjacent to the step area 18 shown disposed of the carrier. The hygiene insert 10 gets through the underwear 22 kept in position. The margins 24 the underwear 22 touch and penetrate the channels 26 '' and 28 '' to order the hygiene insert 10 to bring up against the body of the Trä gers and hold there. The hygiene insert 10 each moves up to the first and second elongated sides 44 and 46 upwards and touches the bars of the wearer. In 9 You can tell that the thighs of the legs 20 are shown to the normal position of the hygiene insert 10 to show when this is located close to the body. During the normal movement of the trunk 14 and the legs 20 such as walking, standing, sitting, running, etc., the thighs can approach each other and the hygiene insert 10 can be compressed. The on the leg openings of the underwear 22 However, acting forces cause the margins 24 the hygiene insert 10 hold against the body.

In 10 is the hygiene insert 10 with an absorption element 40 shown, which has a greater width than that in 6 is shown. As the absorption element 40 further than that in 9 shown absorption element, it can be seen that in each case the first and second longitudinal sides 44 and 46 of the absorption element 40 extend down from the groin area and provide extra protection against fluid passage. The function of underwear 22 opposite the hygiene insert 10 is the same as above with respect to 9 has been described. It should be noted that in 9 and 10 the cover 36 and the shield 38 was removed only for the sake of simplicity. When the hygiene insert 10 both a cover 36 as well as a shield 38 contains, then both would be present in actual use.

In the 11 - 22 is now a number of alternative arrangements for the channels 26 and 28 shown. For the sake of understanding, all items will be considered a hygiene insert 10 with an absorption element 40 and respective first and second grooves or channels 26 and 28 designated. If there are more than two channels, additional numbers are assigned to these additional channels.

In 12 is a bottom view of a hygiene insert 10 with a pair of longitudinally extending channels 26 and 28 shown parallel to each of the first and second elongated sides 44 and 46 are arranged. The first and second channels 26 and 28 are each straight and do not extend over the entire length of the absorbent element 40 , Instead, each extend the first and second channels 26 and 28 over a major portion of the length from about 50 percent to about 90 percent of the total length of the absorbent member 40 , Preferably, the first and second channels extend 26 and 28 each from about 60 percent to about 80 percent of the total length of the absorbent member, and most preferably from about 70 percent to 75 percent of the total length of the absorbent member 40 , The reason why each of the first and second channels 26 and 28 not over the entire length of the absorbent element 40 extend, lies in the fact that the lower surface of the hygiene insert 10 with respect to the body is convex, and therefore the central area of the hygiene insert 10 the really critical area by the side margins 24 the underwear 22 each in the first and second channels 26 and 28 have to penetrate.

The hygiene insert 10 is with a längli chen central axis xx and a transverse central axis yy shown. The first and second channels 26 and 28 can each be in the bottom surface 54 of the absorption element 40 be formed so that they extend in the longitudinal direction outward with the same amount from the transverse central axis yy. Further, they may be equidistant from the elongated central axis xx. Further, each of the first and second channels 26 and 28 from the respective first and second longitudinally extending sides 44 and 46 spaced inwardly by at least about 0.25 inch (about 6.4 mm), and preferably at least about 0.5 inch (about 13 mm). The first and second channels 26 and 28 can each also be arranged parallel to each other. The first and second channels 26 and 28 have a width of about 0.1 inch (about 2.5 mm) to 0.5 inch (about 13 mm), a depth of between about 0.1 inch (about 2.5 mm) to 0.5 inch (about 13 mm) mm) and a length of at least about 3 inches (about 7.6 mm). Preferably, the length of the first and second channels 26 and 28 each in the range of about 3 inches (about 7.6 mm) to a length equal to the length of the sanitary pad 10 is. Most preferably, the length of the first and second channels 26 and 28 each ranging from about 3.5 inches (about 8.9 mm) to about 4.5 inches (about 11.4 mm).

In 12 is an embodiment of a hygiene insert 10 with tapered sides 44 and 46 shown. The rejuvenating sides 44 and 46 give the hygiene insert 10 a non-symmetrical shape, leaving the front end 30 wider than the opposite or rear end 32 is. The first and second channels 26 and 28 are each in the lower surface 54 of the absorption element 40 formed and arranged at an angle to each other, so that these each parallel to the tapered sides 44 and 46 are. As in 11 The first and second channels extend 26 and 28 not over the entire length of the absorption element 40 but only extend over a major part of it. By "body" is meant a range greater than about 50 percent of the total length of the absorbent element 40 is.

In 13 is a hygiene insert 10 shown with an hourglass shape. The hygiene insert 10 has first and second grooves or channels 26 and 28 that are not straight and preferably arcuate. The first and second longitudinally extending sides 44 and 46 are not straight and each of the first and second channels 26 and 28 are each parallel to one of these non-straight sides 44 and 46 aligned. The first and second channels 26 and 28 each may also be arranged so as to be mirror images of each other with respect to the longitudinal center axis xx. The hourglass-shaped hygiene insert 10 is preferred because less absorbent material is located in the center of the crotch area along the transverse central axis yy and this results in a more comfortable sanitary napkin when worn. The first and second channels 26 and 28 each does not extend over the entire length of the absorbent article 10 , As before for the 11 and 12 was noted, the first and second channels can 26 and 28 each over a major part of the length of the hygiene insert 10 extend. By "major part of the length" is meant an amount greater than about 50 percent of the length of the absorbent element 40 is.

Regarding the 14 - 16 It will be recognized that the hygiene deposits tend to coincide with those in each case 11 . 12 and 13 are shown. The only difference is that the first and second grooves or channels 26 and 28 each substantially over the entire length of the absorbent element 40 extend. Depending on the particular construction of each of the hygiene liners, "substantially the entire length" is a distance of approximately between 90 percent to 100 percent of the length of the absorbent element 40 meant. The reason why the first and second channels 26 and 28 each not over the entire length of the absorbent article 10 extend, is that the ends of the hygiene insert 10 can be rounded off and the first and second channels 26 and 28 each arch can be shaped. It would therefore be difficult to use the first and second channels 26 and 28 Each shape so that they are up to the top of the rounded portion of the absorbent element 40 extend.

In the 14 and 15 you realize that the first and second channels 26 and 28 are each straight and parallel to each longitudinally extending sides 44 and 46 are arranged. While in 16 the first and second channels 26 and 28 each not straight and parallel to the non-straight longitudinally extending sides 44 and 46 are arranged.

In the 17 - 19 Now you can see that the hygiene deposits 10 similar to those in the 14 - 16 are shown, with the exception that the first and second grooves or channels 26 and 28 each of different design. In 17 are the first and second channels 26 and 28 each not straight designed. Preferably, the first and second channels 26 and 28 an arcuate profile and therefore can not be parallel with the longitudinally extending sides 44 and 46 be aligned. In 18 are the first and second channels 26 and 28 again each arcuate in the embodiment and are not parallel to the tapered longitudinally extending sides 44 and 46 , In 19 are the first and second channels 26 and 28 straight and therefore can not each parallel to the hourglass-shaped sides 44 and 46 be. In the 17 to 19 you realize that the first and second channels 26 and 28 each substantially over the entire length of the absorbent element 40 extend.

In the 20 - 22 three embodiments are shown, each hygiene liner 10 , several, in the laundry-facing surface 54 of the absorption element 44 includes trained channels. In 20 are two pairs of channels 62 and 64 , and 66 and 68 formed, which have an arcuate profile and are arranged so that the first and second channels 62 and 64 are substantially smaller and are arranged farther from the longitudinal central axis xx than respectively the first and second channels 66 and 68 , The first and second channels 66 and 68 each have a greater total length than each of the first and second channels 62 and 64 , The two channel pairs 62 and 64 and 66 and 68 may be arranged symmetrically about the longitudinal center axis xx or about the transverse center axis yy, if desired.

According to 21 you can see a hygiene insert 10 with two pairs of first and second channels in the garment facing surface 54 of the absorption element 40 are formed. The first pair of channels 62 and 64 is straight and extends substantially the entire length of the absorbent element 40 , The first pair of channels 62 and 64 is at a greater distance from the longitudinal center axis xx than the second pair of channels 66 and 68 away. The second pair of channels 66 and 68 is also straight and extends over the entire length of the absorbent element 40 , Due to the rounded ends of the hygiene insert 10 is the total length of the second pair of channels 66 and 68 slightly larger than the length of the first pair of channels 62 and 64 , All channels can be parallel to each other as well as parallel to the oblong sides 44 and 46 if desired, be arranged. The benefit of providing multiple channels in the bottom surface 54 of the absorption element 40 lies in the fact that the hygiene insert 10 with underwear 22 with varying crotch area width 18 can be used. Certain underwear 22 has a narrower crotch area 18 , By forming two or more pairs of channels in the absorption element 40 you can use the hygiene insert 10 with different underwear 22 who have different widths in the crotch area 18 has, use. Similarly, some users may find it beneficial to use margins 24 the underwear 22 while others have the edges 24 the underwear 22 prefer closer to the center of the elongated center axis xx of the hygiene insert 10 lie.

In 22 is a hygiene insert 10 with three pairs of channels 62 and 64 . 66 and 68 , and 70 and 72 shown in the lower or the laundry facing surface 54 of the absorption element 40 are formed. The two channel pairs are all arcuate and vary in length relative to their positions in the absorbent article 10 , The first pair of arcuate channels 62 and 64 has the shortest length and is at the outermost edge of the hygiene insert 10 arranged. The second pair of channels 66 and 68 is within the first channel pair 62 and 64 arranged and has a slightly larger length. The third channel pair 70 and 72 has the largest length and is within the first and second channel pair 62 and 64 and 66 and 68 arranged. As previously noted, the formation of multiple channels provides the lower surface of the absorbent member 40 the end user a certain flexibility. It also allows the end user the hygiene insert 10 to use with different underwear with a crotch area of different widths.

In the 23 and 24 is an absorbent article 74 shown a body-contacting surface 76 with a first raised longitudinally extending side 78 and a second raised longitudinally extending side 80 having. The absorbent article also has a first end 82 and a second end 84 , As in 24 is best seen, includes the absorbent article 74 a liquid-permeable cover 86 and a liquid-impermeable shield 88 , which together form an absorption element 90 umschießen. The cover 86 , the shielding 88 and the absorbent element 90 are to an absorbent pad 92 shaped. The first and second raised longitudinally extending sides 78 and 80 are each at the upper or body-contacting surface 76 educated. Each of the raised longitudinally extending sides 78 and 80 each has a vertically oriented outer surface 94 and 96 , By "vertically oriented" is meant that the outer surfaces 94 and 96 parallel to the central vertical axis zz or at an acute angle can be arranged. It should be noted that the vertical outer surfaces 94 and 96 straight or not straight. If they are not straight, they can be curved or arched. The upholstery 92 also has a surface facing the laundry 98 opposite to the body-facing surface 76 is aligned. The laundry facing surface 98 is designed to face the inner crotch portion of an undergarment.

In 24 you realize that the cover 86 and the shield 88 each in places 100 and 102 connected to each other on the laundry facing surface 98 are arranged.

However, the point connection may be along the vertical outer surfaces 94 and 96 be appropriate, if desired. Alternatively, the shield 88 and the absorbent element 90 completely off the cover when needed 86 be enclosed.

The absorbent article 74 also includes a pair of flaps 104 and 106 which are of sufficient size to extend at least a portion of the step of undergarment. Preferably, the flaps overlap 104 and 106 and are attached to each other. Alternatively, the flaps 104 and 106 attached or attached to the outer surface of the crotch portion of an undergarment. Each of the flaps 104 and 106 has a near edge 108 and 110 , and one distant edge each 112 and 114 , Each of the near edges 108 and 110 is each at one of the vertically oriented outer surface 94 and 96 attached. Each of the distant edges 112 and 114 extends down and inwards around the crotch area of an undergarment. It is important to note that the flaps 104 and 106 are not designed to extend up into the ledges of the users, as the raised longitudinally extending sides 78 and 80 each fulfill this function. Instead, the pair hangs on flaps 104 and 106 down and inwardly around the crotch area of an adjacent undergarment, thus staining the undergarment with body fluid resulting from the absorbent article 74 can escape, prevent.

The pair of flaps 104 and 106 can be made in any size and shape, provided that they have a width along the transverse central axis yy sufficient to overlap when wound around the undergarment. For best results, the flaps should 106 and 108 but centered on the absorbent article 74 be arranged so that they enclose the central transverse axis yy. It is also beneficial to the flaps 104 and 106 so that they have a length L ₁ , measured along the respective edges 112 and 114 , which is longer than a length L ₂ , each at the near edges 108 and 110 is measured. The length L _{1 of} each of the flaps 104 and 106 can vary from about 2.5 inches to about 5 inches (about 6.4 mm to 12.7 mm), while the length L _{2 is} from about 1 inch to about 2.5 inches (about 2.5 mm to about 6 inches). 4 mm) can vary. For best results, the ratio of L ₂ / L ₁ should be between about 50 percent to about 80 percent, preferably the ratio L ₂ / L ₁ should be between about 60 percent to about 80 percent, and most preferably the ratio of L ₂ / L _{1 are} between about 70 percent to about 75 percent. Using these ratios gives an absorbent article 74 which gives the viewer a visual impression that the pair of flaps 104 and 106 actually larger than their actual dimensions. This is advantageous because it allows the manufacturer to use a minimum amount of material while the consumer is flipping the pair 104 and 106 perceives as larger and thus provides better protection against defilement of the underwear.

Furthermore, with reference to the 23 and 24 includes each of the flaps 104 and 106 a closure means 114 and 116 for mutually fixing the pair of flaps 104 and 106 , In the 23 and 24 is the closing agent 116 shown as an adhesive patch attached to the outer surface of the flap 106 is arranged while the closure means 118 is shown as an adhesive patch on the inner surface of the flap 106 is arranged. The flap 104 is designed to be folded first around the underwear, and the second flap 106 is designed to be subsequently folded around the underwear, leaving the adhesive 118 the adhesive 116 can touch and the pair flaps 104 and 106 firmly held around the underwear. It is also possible the flaps 104 and 106 shorter, so that they do not overlap, but instead a closure means 116 and 118 which are designed to be attached directly to the outer surface of the undergarment. When the flaps 104 and 106 attached to the underwear, are the closure means 116 and 118 on the inner surface of each flap 104 and 106 arranged. In addition to the use of adhesives, the closure means 116 and 118 a mechanical closure is about a hook and eye-like closure. VELCRO ^TM is a type of hook and eye closure. "VELCRO" is a registered trademark of Velcro USA Inc. having an office at 406 Brown Ave., Manchester, NH 03103. Other forms of closures include materials that adhere to one another. For example, you could have the entire flap or part of each of the flaps 104 and 106 each made of a material that adheres to the other material. A cohesive / adhesive element would cause the two flaps 104 and 106 adhere to each other and yet are solvable. Furthermore, one could use a button and a matching buttonhole, a snap closure, or a sort of mechanical mechanism around the pair of flaps 104 and 106 together. All these types of fasteners as well as others the expert Known means are contemplated in this invention.

The absorbent article 74 further includes first and second channels 120 and 122 at the laundry facing surface 98 of the upholstery 92 are formed. The first and second channels 120 and 122 are each sized and designed to intervene with the sides edges of a lingerie into each other. A typical undergarment includes a waist opening and two leg openings having a crotch area disposed between the two leg openings. The crotch region typically includes a side edge or hem that continues over the edge of each leg opening. The two side edges or seams are designed around the first and second channels 120 and 122 touching each other when the underwear is pulled over the body of the consumer. When the underwear is properly seated, the side edges penetrate into the first and second channels, respectively 120 and 122 and hold the absorbent article 74 firmly against the body. By holding the absorbent article 74 close or in contact with the body, one can minimize the amount of liquid that may leak. This is very advantageous since it is possible to significantly reduce the likelihood of the occurrence of a liquid passage when the body fluid enters the absorption element 90 is pulled instead of on the cover 86 to be collected.

Again with respect to 23 one recognizes that the first and second raised longitudinally extending sides 78 and 80 each not over the entire length of the absorbent article 74 extend. Instead, the first and second longitudinally extending sides extend 78 and 80 each along a substantial part of the length of the absorbent article 74 , By "substantial part of the length" is meant a distance ranging from between about 50 percent to about 95 percent of the length of the absorbent article 74 extends. Preferably, the first and second longitudinally extending sides extend 78 and 80 each with a length of between about 60 percent and about 80 percent of the length of the absorbent article 74 ,

Again according to 24 own the outer surfaces 94 and 96 the first and second longitudinally extending sides 78 and 80 each a height H ₁ , which may vary from about 2 mm to about 25 mm. Preferably, the height H _{1 is} at least about 0.2 inches (about 5 mm), and more preferably about 0.25 inches (about 6.4 mm). For thicker absorbent articles 74 For example, the height H _{1 should be} about 0.5 inches (about 12.7 mm). Each of the raised longitudinally extending sides 78 and 80 each has an inside height H ₂ that is from a vertex of each of the sides 78 and 80 to the body-contacting surface 76 is measured. The height H ₂ is less than H ₁ and normally ranges between about 25 percent to about 75 percent less than the height H ₁ . Preferably, the height H _{2 is} at least about 50 percent less than the height H ₁ .

The height H _{1 of} the first and second raised longitudinally extending sides 78 and 80 should each be sized and designed to at least partially and preferably completely touch the bars of the user. This ensures that the flaps 104 and 106 only downwards and inwards from the outer surfaces 94 and 96 point. The flaps 104 and 106 are not forced up by the underwear.

In 25 is a human body that represents a hull 124 with a pair of thighs 126 and 128 that stand out from it. On the inside of each thigh 126 and 128 is each a bar 130 and 131 caused by the transition of the respective thigh 126 and 128 to the hull 124 is formed. Each of the strips 130 and 131 each includes a fold 132 and 134 , The crotch area of an underwear 136 is shown as having two side margins or seams 138 and 140 which has a portion of each leg opening in the underwear 136 form. When the underwear 136 over the hull 124 is pulled up, penetrate the margins 138 and 140 into the channels or ribs 120 and 122 A, are engaged with these or are absorbed by these, thus the absorbent article 74 firmly against the bars 130 and 131 to keep. The on the margins 138 and 140 the underwear 136 acting forces cause the first and second raised longitudinally extending sides 78 and 80 each in the folds 132 and 134 penetrate, and therefore form a seal with the body. This seal ensures that leakage of a fluid is reduced when the absorbent article is worn.

In 25 is the absorption element 90 without the cover 86 and the shield 88 shown. This is only for the purpose of a clear representation of the absorbent article 74 , The first and second raised longitudinally extending sides 78 and 80 should be sized and designed to easily fit the strips 130 and 131 to touch. By this is meant that the height, width and length of the first and second raised longitudinally extending sides 78 and 80 each designed to be with the ledges 130 and 131 of the consumer. The seitli che distance between the first raised side 78 and the second sublime page 80 should be such that these are vertical with the wrinkles 132 and 134 aligned. to Note that the first and second raised longitudinally extending sides 78 and 80 not necessarily completely in the folds 132 and 134 the last 130 and 131 but they should at least partially invade the folds 123 and 124 penetration. Since the anatomy of women is different, it may be advantageous to have the first and second longitudinally extending sides 78 and 80 straightforward for some products and non-straightforward for other products. For example, it may be for the in 23 shown absorbent article 74 with straight sides, the first and second raised longitudinally extending sides 78 and 80 each straight, while in an hourglass-shaped absorbent article the first and second raised longitudinally extending sides 78 and 80 each may not be straight or arcuate.

If 25 attentive, you notice that the underwear 136 adjacent to the absorbent article 74 is arranged, and the pair flaps 104 and 106 extends downwards and inwards so that it overlaps with each other. The pair of flaps 104 and 106 is with the locks 116 and 118 attached to each other. In this position, the flaps surround 104 and 106 completely the crotch area of the underwear 136 and prevent the underwear, especially the edges 138 and 140 , wetting with body fluid.

In 26 is now the absorbent article 74 shown, with the cover 86 and the shield 88 are removed to clear the raised sides 78 and 80 to show those engaging with the wrinkles 132 and 134 each of the bars 130 and 131 are. In this embodiment, the first and second channels are respectively 120 and 122 arranged away from the vertical central axis zz, so that these become the folds 132 and 134 better aligned vertically. This embodiment allows the removed side edges 142 and 144 of the absorption element 90 down and away from the wrinkles 132 and 134 extend. This downward orientation causes the flaps 104 and 106 to move inward and towards each other to a greater extent than in 25 is shown. As in 25 the flaps extend 104 and 106 however, do not go up, but only extend down and in to wrap around the underwear 136 to arch and enclose them. Ankumer ken is that the distance between the channels 120 and 122 but a distance of about 2 inches to about 4 inches (about 51 mm to 102 mm) is useful. A more preferred distance between the channels 120 and 122 is between about 2 inches to about 3 inches (about 51 mm to about 76 mm).

In 27 is an alternative embodiment of an absorbent article 146 shown with an hourglass construction. The hourglass structure has a first raised longitudinally extending side 148 and a second raised longitudinally extending side 150 , Each of these sublime pages 148 and 150 is not straightforward in her appearance. For this reason, the first and second raised longitudinally extending sides 148 and 150 each close to each other at the transverse center line yy near the ends 82 and 84 arranged separately with a larger distance. Each of the first and second raised longitudinally extending sides 148 and 150 also extends substantially the entire length of the absorbent article 146 , In a typical hourglass arrangement, the raised sides 148 and 150 have an arcuate or curved arrangement.

In 28 is yet another embodiment of an absorbent article 152 shown with an oval shape. The absorbent article 152 includes a first raised longitudinally extending side 154 and a second raised longitudinally extending side 156 , The two raised longitudinally extending sides 154 and 156 are curved or not straight in shape and extend over a length slightly smaller than the total length of the absorbent article 152 is. The first and second raised longitudinally extending sides 154 and 156 are each farther from the transverse center line yy and are near the ends 82 and 84 closer together. The difference in size, arrangement and location of the first and second raised longitudinally extending sides 148 and 150 , and 154 and 156 allows a manufacturer to make absorbent articles that best fit the anatomy of a number of different women. Some women like the hourglass-shaped absorbent article 146 while others prefer the oval shaped article 152 while others prefer the more rectangular shaped absorbent article 74 to prefer.

In the 29 - 31 Now three further embodiments are shown. In 29 is an absorbent article 158 shown, with the cover 86 and the shield 88 removed to more clearly the penetration of the underwear 136 into the channels 120 and 122 to show. Each of the channels 120 and 122 each has an inner wall, 160 and 162 , each with a flap 164 and 166 is appropriate. Each of the flaps 164 and 166 each has a near edge 168 and 170 , and one distant edge each 172 and 174 , The near edges 168 and 170 are designed to be on the inside wall 160 and 162 each of the channels 120 and 122 to be attached. Each of the flaps 164 and 166 also has a fastener, such as a stain or a patch of adhesive or a mechanical fastener designed to attach to the lower surface of the undergarment 136 to be attached. fold 164 and 166 do not overlap each other but are instead sized and designed to be down and inward around a portion of the underwear 136 to extend and attached directly to the underwear.

A unique advantage for fixing the flaps 164 and 166 on a surface of the channels 120 and 122 is that the first and second raised longitudinally extending sides 78 and 80 can penetrate into the folds of the bar and not down by attaching the flaps 164 and 166 on the underwear 136 be moved. Another advantage of this embodiment is that the absorption element 90 can be made further than necessary while the flaps 164 and 166 can be reduced in size. As the flaps 164 and 166 down and in from the channels 120 and 122 instead of on the outside edges of the absorbent element 90 , A third advantage to getting away from the channels 120 and 122 downwardly extending flaps 164 and 166 is that they help, the margins 138 and 140 the underwear 136 to hold in position. When the flaps 164 and 166 as in 29 attached, can the underwear 136 not easily outward away from the channels 120 and 122 move.

In 30 is now an absorbent article 180 shown by the in 29 shown embodiment distinguished in two notable ways. First, the pair is flaps 104 and 106 designed to overlap with each other and through the fasteners 116 and 118 to be connected to each other. Second, the first and second raised longitudinally extending sides 78 and 80 each within the vertical outer surfaces 94 and 96 arranged. The close fitting arrangement of the first and second raised longitudinally extending sides 78 and 80 each allows that the absorbent article 180 better for women with narrower spacing fits. Again, the attachment of the flaps helps 104 and 106 on the walls 160 and 162 of the channels 120 and 122 with, the underwear 136 to hold in position.

Finally, in 31 an absorbent article 182 with a pair of flaps 136 and 166 shown. Every flap 164 and 166 has a near edge 168 and 170 and one distant edge each 172 and 174 , The difference between the in 31 embodiment shown and in 29 shown embodiment is that in 31 the flaps 164 and 166 on a lower surface of the absorbent article 182 near their near edges 168 and 170 are attached. The flaps 164 and 166 are fixed so that they extend inwards in the direction of the vertical center line zz. The flaps are sized and designed so that they do not overlap with each other. Each of the flaps 164 and 166 each has a fastener 176 and 178 such as an adhesive that is used to hold the flaps 164 and 166 detachable on the underwear 136 to fix. It is worth noting that it can be easier, the flap 164 and 166 to attach to the lower surface of the absorbent article, as in 31 is shown instead of trying on the inner surface of each of the channels 120 and 122 to fix.

Even though the invention in connection with a specific embodiment It is self-evident that many alternatives Modifications and variations for the skilled person in the light of the preceding description obvious are. Consequently, this invention intends all such alternatives, To embrace modifications and variations that are within the basic idea and scope of the attached claims lie.
