technical field

The present invention generally relates to absorbent articles, such as labial pads, configured for placement within the vestibule of a female wearer. More specifically, the present invention relates to labial pads having at least one flap extending outwardly from the periphery of the labial pad.

Background technique

Absorbent articles of various manners and types of constructions for absorbing bodily exudates such as menses are well known. With regard to feminine hygiene products, two basic types of feminine hygiene protection products have been known in the art: sanitary napkins, which are intended to be worn externally in the vulvar area, and sanitary napkins, which are intended to be placed inside the vagina and stop menstruation therefrom. In addition, a hybrid feminine hygiene protection device has been proposed, trying to mix the two structure types into one type of device, but there is no meaningful method within an acceptable range, and the appropriate advantages of known devices are often Overshadowed by the presence of verifiable structural and functional deficiencies. Some other insertion devices have also been proposed, such as labial or interlabial devices, which are characterized by having a portion located at least partially outside of the wearer's vestibule.

These prior devices do not adequately address consumer demand for smaller devices that are worn between the labia of female wearers. In view of this, several manufacturers have produced labial pads of smaller sizes than the prior devices described above. However, the configuration of these devices does not take into account the variations that exist in women with respect to the location of the vagina and urethral opening. For example, some current devices typically place the majority of the absorbent core in the center of the device with a small portion of the absorbent core at the ends. This device provides little protection for most women whose vaginal and urethral openings are not centrally located in the vestibule. Other devices provide uneven distribution of the absorbent core over substantially the entire length of the device. However, the designs of these devices generally do not significantly enhance the personal fit and/or absorbent core capacity.

Another factor affecting consumer acceptance is ease of use, including placing and/or removing the labial pads into the correct position. Typically, the wearer grasps the labial pads with their fingers and places them in the desired location on their vestibule. The wearer also needs to grasp the labial pad to remove it, especially when urinating. The placement and/or removal of conventional labial pads is often accompanied by difficulties. Accordingly, there is a need for an improved device that facilitates hygienic placement of the labial pads into place within the vestibule, and hygienic removal of the labial pads from the vestibule.

Detailed ways

See Figures 1 to 36, wherein like reference numerals are used for like parts in each figure. Figure 2 shows an absorbent article, such as a labial pad, indicated at 40, which is placed in the wearer's vestibule, indicated at 42 (see Figure 1). As used herein, the term "labial pad" refers to a device having at least some absorbent components, which, during use, is specifically configured to be placed between the labia majora, extending at least partially into the vestibule (42) of a female wearer. For the convenience of subsequent descriptions, the vestibule (42) is considered intralabial from near the caudal point of the anterior labial commissure (44), extending posteriorly to the posterior labial commissure (46) and internally by the floor of the vestibule (48) defined area (not explicitly shown in the figure). It will be well understood by those skilled in the art that there is a range of variation in the relative size and shape of the labia majora and minora in females when defining the vestibule (42) contour as above. However, to facilitate the description of the present invention, this difference is not specified, it is considered that in any case when placing the absorbent article (40) in the vestibule (42), it is necessary to place the absorbent article between the labia majora, The labia minora are not considered. Caudal to the vestibule (42) is the perineum (50), which opens to the anus (52) in the region of the buttocks (54). Relatedly, located within the vestibule (42) itself are the main urogenital organs, which include the vaginal opening (56), urethral opening (58) and clitoris (60). A brief description of the anatomy has been given above, and for the purposes of the present invention, the vestibule (42) is generally considered to be the area between the posterior labial commissure (46) and the clitoris (60). However, for a better understanding of the description of the female anatomy, please refer to Henry Gray's Anatomy of the Human Body, USA, 30th Edition (Carmine D. Clemente ed. Lea & Febiger, 1985), pp. 1571-1581.

Referring to the anatomical configuration shown in Figures 1 and 2, the absorbent article (40) is positioned at least partially within the vestibule (42) for at least partially entrapping fluid expelled from these portions. At this point, although the absorbent article (40) can be used as an incontinence product for absorbing urine, such as the urine produced during incontinence for infants and women, its main function is to absorb the urine through the vaginal opening (56 ) out of menstruation.

One form of absorbent article (40) is shown in Figure 3 having a longitudinal axis (L) extending generally in the X direction. As used herein, the term "longitudinal" refers to a line, an axis or a direction in the plane of the absorbent article (40) which is generally aligned with the left half of a standing female wearer in use of the absorbent article and The vertical plane (eg, approximately parallel) of the right half of the body. This longitudinal direction is indicated by the X-axis in FIG. 3 . The absorbent article (40) also has a transverse major axis (T). As used herein, the terms "transverse", "lateral" or "Y-direction" generally refer to a line, an axis or a direction perpendicular to the longitudinal direction. This lateral direction is indicated by the Y axis in FIG. 3 . "Z-direction" is typically a line, an axis or a direction generally parallel to the aforementioned vertical plane. This Z direction is represented by a Z axis in FIG. 4 . The term "upper" generally refers to a direction toward the wearer's head, while the terms "lower" or "downward" generally refer to a direction toward the wearer's feet. For ease of description, each layer of the absorbent article (40), for example, the fluid-permeable cover layer (62), the liquid-impermeable barrier layer (64), and/or the absorbent body (66) has an upper surface Or the body-facing surface, the lower surface is also described as the surface opposite the upper or body-facing surface.

Referring to Figure 5, the absorbent article (40) shown therein comprises a fluid permeable cover (62), a liquid impermeable barrier (64) and an absorbent material between the cover and the barrier. body (66). As shown in Figure 6, the absorbent body (66) has a first end region (70), a second end region (72) and a central region (74) between the two end regions. The absorbent article (40) should be sized and shaped such that at least a portion of the absorbent article can be placed within the vestibule (42) of a female wearer. In addition, the absorbent article (40) needs to at least partially absorb and block the flow of menses, urine or other exudates from the wearer's vagina (56) and/or urethra (58).

The absorbent body (66) or absorbent article (40) generally has a geometric shape extending between a first spaced lateral end surface (76) and a second lateral end surface (78), the absorbent body (66) or The absorbent article (40) also includes spaced-apart first (80) and second longitudinal sides (82) in the region between the transverse end faces (76, 78), thus defining the overall geometric shape. The combination of the above parts is sometimes referred to as the perimeter (ie, the parts form the periphery).

The shape of the absorbent body (66) is an important factor affecting the overall size and effectiveness of the absorbent article (40). Typically, the absorbent body (66) has a maximum width (W _max ) and a minimum width (W _min ) from one longitudinal side to the opposite longitudinal side along a line generally parallel to the transverse major axis (T). The distance measured by (80, 82), the minimum width is also the distance measured from one longitudinal side to the opposite longitudinal side (80, 82) along a line generally parallel to the transverse main axis (T). The maximum width (W _max ) of the absorbent body (66) is typically not greater than about 30; can be selected to be not greater than about 40; can be selected to be not greater than about 50; can be selected to be not greater than about 60; about 70 mm; the minimum width ( _Wmin ) of the absorbent body (66) is typically not less than about 30; alternatively not less than about 20; alternatively not less than about 10; or alternatively not less than about 5 mm. Thus, while the approximate width of the absorbent body may vary depending on the overall design and intended location of the absorbent article (40) within the female wearer's vestibule (42), the absorbent body (66) may have a width of not less than about 5 mm to not less than about 5 mm. A width range between greater than about 70mm. Those skilled in the art will readily recognize that certain types of absorbent bodies (66), or certain absorbent articles (40), may have a minimum width (W _min ) equal to a maximum width (W _max ). In these cases, only its maximum width (W _max ) is usually referred to.

The absorbent body (66) also has a maximum length ( _Lmax ) which is the distance measured from one transverse end face to the opposite transverse end face (76, 78) along a line generally parallel to the longitudinal axis (L) . The maximum length (L _max ) of the absorbent body (66) is typically not greater than about 40; optionally not greater than about 50; optionally not greater than about 60; optionally not greater than about 70; optionally not greater than about 80; may be selected to be no greater than about 90; or may be selected to be no greater than about 100 mm. The absorbent body (66) may also have a minimum length ( _Lmin ) measured along a line generally parallel to the longitudinal axis (L) from one transverse end face to the opposite transverse end face (76, 78) distance. The minimum length (L _min ) of the absorber (66) is typically not less than 100; can be selected to be not less than 90; can be selected to be not less than 80; can be selected to be not less than 70; can be selected to be not less than 60; Not less than 50; or optionally not less than 40mm. Thus, although the approximate length of the absorbent body may vary depending on the overall design and intended location of the absorbent article (40) within the female wearer's vestibule (42), the absorbent body (66) may have a length of not less than 40mm to not more than Length range between 100mm. Those skilled in the art will readily recognize that certain absorbent bodies (66), or certain absorbent articles (40), may have a minimum length (L _min ) equal to their maximum length (L _max ). In these cases, at least as shown in Figures 6, 8 and 9, only its maximum length (L _max ) is generally referred to. As shown at least in FIGS. 7 and 10 , the maximum length (L _max ) of various absorbent bodies ( 66 ) or various absorbent articles ( 40 ) is not equal to their minimum length (L _min ).

The first end region (70) and the second end region (72) extend at least outwardly from the central region (74) to the transverse end faces (76 and 78, respectively) of the absorbent body (66) by not less than the maximum length of the absorbent body A distance of about 30% of (L _max ); may be selected to be not less than about 20%, or may be selected to be not less than about 10% of the maximum length (L _max ) of the absorbent body. The first end region (70) and the second end region (72) extend at least outwardly from the central region (74) to the transverse end faces (76 and 78, respectively) of the absorbent body (66) by a distance not greater than the maximum length of the absorbent body A distance of about 20% of (L _max ); optionally no greater than about 30%; or alternatively no greater than about 40% of the maximum length (L _max ) of the absorbent body. As such, the end regions (70, 72) may occupy a minimum of about 20% of the maximum length ( _Lmax ) of the absorbent body (66) to a maximum of about 80% of the maximum length ( _Lmax ) of the absorbent body (66). The approximate size of the absorbent body may vary depending on the overall design and intended location of the absorbent article (40) within the female wearer's vestibule (42).

It is generally desirable for the absorbent article (40) to have sufficient capacity to absorb and retain a desired amount or type of bodily exudates. Absorbent capacity is provided by a fluid retaining core or absorbent body, generally designated 66 . At least for menses, it is desirable that the absorbent body (66) have a minimum capacity of not less than about 19 g/g; optionally not less than about 18 g/g; optionally not less than about 17 g/g; optionally not less than about 16 g/g g; alternatively not less than about 15 g/g; alternatively not less than about 14 g/g; alternatively not less than about 13 g/g; alternatively not less than about 12 g/g; alternatively not less than about 11 g/g g; alternatively not less than about 10 g/g; alternatively not less than about 9 g/g; alternatively not less than about 8 g/g; alternatively not less than about 7 g/g; alternatively not less than about 6 g/g g; alternatively not less than about 5 g/g; alternatively not less than about 4 g/g; alternatively not less than about 3 g/g; alternatively not less than about 2 g/g; alternatively not less than about 1 g /g. The absorbent body (66) may also have a maximum capacity of not greater than about 5 g/g, optionally not greater than about 6 g/g; optionally not greater than about 7 g/g; optionally not greater than about 8 g/g; optionally Optionally not greater than about 9 g/g; optionally not greater than about 10 g/g; optionally not greater than about 11 g/g; optionally not greater than about 12 g/g; optionally not greater than about 13 g/g; optionally Optionally not greater than about 14 g/g; optionally not greater than about 15 g/g; optionally not greater than about 16 g/g; optionally not greater than about 17 g/g; optionally not greater than about 18 g/g; optionally is not greater than about 19 g/g; alternatively is not greater than about 20 g/g; alternatively is not greater than about 25 g/g; alternatively is not greater than about 30 g/g. Thus, while the approximate capacity of the absorbent body may vary depending on the overall design and intended location of the absorbent article (40) within the female wearer's vestibule (42), the absorbent body (66) may have a capacity of not less than about 1 g/g. Up to an absorbent capacity range of not more than about 30 g/g. Those skilled in the art will readily recognize that the addition or coating of superabsorbent polymers to absorbent bodies typically has the effect of significantly increasing the absorbent capacity.

Describing the individual components in more detail, the absorbent body (66) has an upper surface or body-facing surface and a lower surface (opposite to the upper surface or body-facing surface), and may include any absorbable and/or absorbent Retain material of expected bodily discharge thereafter. Suitable materials are generally hydrophilic, compressible and comfortable. The absorbent body (66) may be constructed of any material known to those skilled in the art. Examples of such materials include, but are not limited to, various natural or synthetic fibers, multiple layers of creped cellulose wadding, loft cellulose fibers, rayon or other regenerated cellulosic materials, wood pulp fibers or comminuted wood pulp fibers, Bulky materials, textile materials, polyester and polypropylene fiber blends, absorbent foams, absorbent sponges, superabsorbent polymers, coated superabsorbent polymers, fiber bundles or nits, or any equivalent material or combinations of these materials. Materials suitable for use are also hydrophobic materials which have been rendered hydrophilic according to any known method. However, the total absorbent capacity of the absorbent body (66) should be compatible with the design displacement and intended use of the absorbent article (40). Additionally, the size and absorbent capacity of the absorbent body (66) can vary. Accordingly, the size, shape and configuration of the absorbent body (66) may vary (for example, the absorbent body may have a varying thickness as shown in at least Figures 11 and 12, or may have a hydrophilic gradient or may contain superabsorbent polymers or their analogues).

The absorbent body (66) typically has a thickness, caliper, or height (H), at least as shown in Figure 4, the thickness being measured along a line generally parallel to the Z-axis. The minimum thickness of the absorbent body (66) is typically not less than about 9 mm; optionally not less than about 8 mm; optionally not less than about 7 mm; optionally not less than about 6 mm; optionally not less than about 5 mm; optionally is not less than about 4 mm; alternatively is not less than about 3 mm; alternatively is not less than about 2 mm; alternatively is not less than about 1 mm; or alternatively is not less than about 0.5 mm. The maximum thickness of the absorbent body (66) is typically no greater than about 2 mm; optionally no greater than about 3 mm; optionally no greater than about 4 mm; optionally no greater than about 5 mm; optionally no greater than about 6 mm; optionally is no greater than about 7 mm; alternatively is no greater than about 8 mm; alternatively is no greater than about 9 mm; or alternatively is no greater than about 10 mm. Thus, while the approximate thickness of the absorbent body may vary depending on the overall design and intended location of the absorbent article (40) within the female wearer's vestibule (42), the thickness of the absorbent body (66) is about 10 mm or less.

The absorbent body (66) also needs to have a relatively low density, which means it is expected to feel comfortable. Typically, the density of the absorbent body is less than about 0.5 g/cc. In other words, the absorbent body (66) typically has a maximum density of not greater than about 0.5 g/cc; optionally not greater than about 0.4 g/cc; optionally not greater than about 0.3 g/cc; optionally not greater than about 0.3 g/cc; Greater than about 0.2 g/cc; optionally not greater than about 0.1 g/cc; alternatively not greater than about 0.09 g/cc; alternatively not greater than about 0.08 g/cc; alternatively not greater than about 0.07 g/cc can be selected to be not greater than about 0.06 g/cc; can be selected to be not greater than about 0.05 g/cc; can be selected to be not greater than about 0.04 g/cc; can be selected to be not greater than about 0.03 g/cc; Greater than about 0.02 g/cc. The absorbent body (66) also typically has a minimum density of typically not less than about 0.01 g/cc; optionally not less than about 0.02 g/cc; optionally not less than about 0.03 g/cc; optionally not less than about 0.04 g/cc; alternatively not less than about 0.05 g/cc; alternatively not less than about 0.06 g/cc; alternatively not less than about 0.07 g/cc; alternatively not less than about 0.08 g/cc; Selected to be not less than about 0.09 g/cc; alternatively selected to be not less than about 0.1 g/cc; alternatively selected to be not less than about 0.2 g/cc; alternatively selected to be not less than about 0.3 g/cc; 0.4g/cc. Thus, while the approximate density of the absorbent body may vary depending on the overall design and intended location of the absorbent article (40) within the female wearer's vestibule (42), the density of the absorbent body (66) may range up to about 0.5 g/cc.

The absorbent body (66) also needs to have a basis weight of less than about 600 grams per square meter. In other words, the absorbent body (66) typically has a maximum basis weight of not greater than about 600 grams/square meter; optionally not greater than about 500 grams/square meter; optionally not greater than about 400 grams/square meter; Can be selected to be no greater than about 300 grams per square meter; can be selected to be no greater than about 200 grams per square meter; or can be selected to be no greater than about 100 grams per square meter. Typically, the absorbent body (66) also has a minimum basis weight typically not less than about 0.1 grams per square meter; optionally not less than about 50 grams per square meter; optionally not less than about 100 grams per square meter; Selected to be not less than about 150 grams/square meter; Optionally not less than about 200 grams/square meter; Optionally not less than about 250 grams/square meter; Optionally not less than about 300 grams/square meter; Not less than about 350 g/m2; alternatively not less than about 400 g/m2; alternatively not less than about 450 g/m2; alternatively not less than about 500 g/m2; Less than about 550 g/m2. Thus, the basis weight of the absorbent body (66) is about 600 grams, although the approximate basis weight of the absorbent body may vary depending on the overall design and intended location of the absorbent article (40) within the female wearer's vestibule (42). / square meter or less. A specific example of a suitable absorbent is similar to the coform material composed of a mixture of polypropylene and cellulose fibers, used in KOTEX maxi pantiliners and available from Kimberly Corporation of Neenah, Wisconsin (WI).

An optional barrier layer (64) is typically located on the lower surface of the absorbent body (66) and may be constructed of any desired liquid impermeable material. The barrier layer (64) is expected to allow air and moisture to pass through the absorbent body (66), while blocking the passage of bodily fluids. An example of a suitable barrier material is a microembossed, polymeric film, such as polyethylene, polypropylene or polyester, having a minimum thickness of not less than about 0.025 mm and a maximum thickness of not greater than about 0.13 mm. Bicomponent films can also be used, as well as woven and nonwoven fibers that have been treated to render them impermeable to liquids. Another example of a suitable material is closed cell polyolefin foam. Closed cell polyethylene foam also works satisfactorily.

The barrier layer (64) and the absorbent body (66) may be maintained in fixed connection by bonding all or part of the adjacent surfaces to each other. Various methods known to those skilled in the art can be applied to realize this fixed connection. Examples of such methods include, but are not limited to, ultrasonics, thermal bonding, or the application of various forms of adhesive between two adjacent surfaces. A specific example of a barrier material is similar to polyethylene film used in KOTEX pantiliners and available from Pliant Corporation, Schaumburg, IL, USA.

The optional liquid permeable cover layer (62) has an upper surface and a lower surface, the upper surface typically contacts the wearer's body and receives bodily exudates. It is desirable that the cover layer (62) is made of a material that is flexible and that it is not irritating to the vestibule (42) of the female wearer. As used herein, the term "flexible" means conforming to and conforming to the surface of the body or susceptible to deformation in the presence of external forces.

The cover layer (62) is used to provide comfort and conformability, and it functions to direct body waste away from the body and from the body to the absorbent body (66). The cover layer (62) should maintain little or no fluid in its structure, thereby providing a non-irritating surface that can be relatively comfortable and adjacent to the tissues within the vestibule (42) of a female wearer. The construction of the cover layer (62) may be any woven or nonwoven material that is also readily permeable to bodily fluids that contact its surface. Examples of suitable materials include rayon, polyester, polypropylene, polyethylene, nylon or other thermally bondable fibers, polymers of polyolefins such as polypropylene, polyethylene, linear low density polyethylene, aliphatic esters such as polylactic acid Bonded carded webs of the like, finely perforated film webs and mesh materials are also suitable. A specific example of a suitable cover material is similar to bonded carded webs made of polyolefins and polyethylene for cover glue applied to KOTEX pantiliners and available from Sandler, Germany. Other examples of suitable materials include polymeric materials and nonwoven fibrous materials. Synthetic materials are typically in the form of monolithic sheets, which are usually made by extruding the polymer onto a web of spunbond material. The fluid permeable cover layer (62) may also include a plurality of apertures formed therein which increase the rate of penetration of body fluids into the absorbent body (66).

Physiological hydration covers are also suitable for application. As used herein, the term "physiologically hydrated" means that when the absorbent article (40) is placed in the environment of the vestibule, the coverage of the wet interface between the tissue of the vestibule (42) and the absorbent article (40) is properly maintained layer material. The placement of fibers or fibrous structures within the moist tissue environment of the vestibule is expected to be comfortable, and its role is self-evident that the absorbent article contains bodily fluids that exit the vestibule and directs them toward the absorbent body (66). Thus, a covering that is not "hydrated" in the traditional sense (at which time the covering is dry) prior to application maintains (at least does not impede maintaining) the proper moisture level or balance required for (inside) the vestibule.

At least a portion of the surface of the cover layer (62) is treated with a surfactant to make it more hydrophilic. As a result, bodily fluids can more easily pass through the cover layer (62). Surfactants may also reduce the likelihood that bodily fluids, such as menses, will be absorbed by the cover (62) instead of by the absorbent body (66). Suitable means are used to distribute the surfactant substantially uniformly over at least a portion of the upper surface of the cover layer (62), which covers the upper surface of the absorbent body (66).

The cover layer (62) and the absorbent body (66) may be maintained in fixed connection by bonding all or part of the adjacent surfaces to each other. Various methods known to those skilled in the art can be applied to realize this fixed connection. Examples of such methods include, but are not limited to, applying various forms of adhesive between two adjacent surfaces, wrapping at least a portion of the adjacent surface of the absorbent body with an adjacent surface of a portion of the cover layer, At least a portion of the adjacent surface of the absorbent body is fused to an adjacent surface of the portion of the cover layer.

The cover layer (62) is typically located on the upper surface of the absorbent body (66), but may optionally surround and partially or completely surround the absorbent body. Optionally, the cover layer (62) and barrier layer (64) have peripheries extending outwardly beyond the perimeter of the absorbent body (66) and joining the peripheries to form an edge (84), as at least shown in FIG. 5 . Known techniques are applied, such as gluing, crimping, heat sealing or the like. The edge (84) may be integrally formed such that the entire perimeter of the absorbent body (66) is bounded by its junction, or the cover layer (62) and barrier layer (64) may be partially perimeter joined. To reduce the potential for irritation and/or discomfort to the wearer of the absorbent article (40), it is desirable that the edge (84) and at least the area of the absorbent article immediately adjacent the edge be soft, compressible and conformable. It is desired that any edge (84) of such a structure has a width of no greater than about 10 mm; alternatively no greater than about 9 mm; alternatively no greater than about 8 mm; alternatively no greater than about 7 mm; alternatively no greater than about 6 mm; can be selected to be no greater than about 5 mm; can be selected to be no greater than about 4 mm; can be selected to be no greater than about 3 mm; can be selected to be no greater than about 2 mm; or can be selected to be no greater than about 1 mm. Additionally, the width of any edge (84) of such a structure is not less than about 0.5mm; optionally not less than about 1mm; alternatively not less than about 2mm; alternatively not less than about 3mm; alternatively not less than about 4mm ; alternatively not less than about 5 mm; alternatively not less than about 6 mm; alternatively not less than about 7 mm; alternatively not less than about 8 mm; alternatively not less than about 9 mm. Thus, although the approximate width of the edge may vary depending on the overall design and intended location of the absorbent article (40) within the female wearer's vestibule (42), the edge (84) of such a structure may have a thickness ranging from no less than about 0.5mm to The width range of not more than 10mm. In another version, the cover layer (62) and/or the barrier layer (64) may have a periphery connected to the periphery of the absorbent body (66).

An ideal bending axis (F) can be chosen to lie on the longitudinal axis of the absorbent body (66) or parallel to the longitudinal axis (L). Desirably the bending axis (F) is generally longitudinal, i.e. extending along the X direction and its distance from the longitudinal axis (L) is no greater than about 10 mm; optionally no greater than about 9 mm; optionally no greater than about 8 mm; optionally can be selected to be not greater than about 7 mm; alternatively can be selected to be no greater than about 6 mm; alternatively can be selected to be no greater than about 5 mm; alternatively can be selected to be no greater than about 4 mm; alternatively can be selected to be no greater than about 3 mm; No greater than about 1 mm. Desirably, the ideal bending axis (F) is aligned along the longitudinal major axis (L). Desirable bending axis (F) typically has a minimum longitudinal extension of not less than about 90% of the maximum length ( _Lmax ) of the absorbent body (66); optionally not less than about 80%; optionally not less than about 70%; optionally is not less than about 60%; alternatively is not less than about 50%; or alternatively is not less than about 40% of the maximum length ( _Lmax ) of the absorbent body (66). The desired flex axis (F) typically extends longitudinally no greater than about 50% of the maximum length ( _Lmax ) of the absorbent body (66); optionally no greater than about 60%; optionally no greater than about 70%; optionally Not greater than about 80%; optionally not greater than about 90%; or alternatively not less than 100% of the maximum length ( _Lmax ) of the absorbent body (66). The desired bending axis (F) may naturally result from the size, shape and/or configuration of the absorbent body (66), or the absorbent body may have a soft axis or region to obtain the desired bending axis. The curved shaft (F) may also be formed by any technique known to the person skilled in the art, including for example scoring, pre-folding, notching, embossing or similar techniques. Although the ideal bending axis (F) described here is located in the absorber (66), those skilled in the art can understand that the ideal bending axis (F) can be anywhere in the cover layer (62), barrier layer (64) and/or absorber, cover and barrier, cover and absorber, or barrier and absorber. The desired axis of bend (F), if present, typically allows for easier folding of the absorbent article (40) prior to placement in the vestibule of a female wearer.

The absorbent article (40) also has a thickness, dimension or height (H), as at least shown in Figures 4 and 5, the thickness being measured along a line substantially parallel to the Z-axis. The absorbent article (40) typically has a minimum thickness of not less than about 9 mm; optionally not less than about 8 mm; optionally not less than about 7 mm; optionally not less than about 6 mm; optionally not less than about 5 mm; Optionally not less than about 4 mm; alternatively not less than about 3 mm; alternatively not less than about 2 mm; alternatively not less than about 1 mm; alternatively not less than about 0.5 mm. The maximum thickness of the absorbent article (40) is typically no greater than about 1 mm; optionally no greater than about 2 mm; optionally no greater than about 3 mm; optionally no greater than about 4 mm; optionally no greater than about 5 mm; Selected to be no greater than about 6 mm; alternatively no greater than about 7 mm; alternatively no greater than about 8 mm; alternatively no greater than about 9 mm; or alternatively no greater than about 10 mm. Thus, the thickness of the absorbent article (40) is about 10 mm or less, although the approximate thickness of the absorbent article may vary depending on the overall design and intended location of the absorbent article (40) within the female wearer's vestibule (42).

longitudinal side

As shown at least in Figures 12, 13 and 14, typically, the absorbent article (40) is positioned along an axis lying at or parallel to the longitudinal axis (L) prior to placement in the vestibule (42) of a female wearer. fold. When folded along such an axis, the absorbent article (40) will form a notch (92) which protects the wearer's fingers from contamination when placing the absorbent article in the vestibule. Once inserted, the absorbent article (40) may tend to expand to fill the vestibule, thereby maintaining the upper surface of the absorbent article in contact with the tissue of the vestibule (42). The absorbent article (40) may be resiliently biased along the axis about which the absorbent article is folded to increase the tendency of the absorbent article to unfold. Alternatively, the absorbent body (66) of the absorbent article (40) may be thicker along its longitudinal edges, at least as shown in Figures 11 and 12, thus also exhibiting a biasing effect which would typically allow the The upper surface of the absorbent article (40) contacts the tissue of the vestibule (42). The absorbent article (40), however, does not necessarily require any additional features to maintain contact with the tissue of the female wearer's vestibule (42). The naturally wetted surface of the vestibular (42) tissue typically exhibits a tendency to remain in contact with the upper surface of the absorbent article (40).

As noted above, the wearer may fold the absorbent article (40) along an axis located at or parallel to the longitudinal axis (L) prior to placing the absorbent article (40) within the vestibule (42). Thus, as shown at least in Figure 14, the wearer can hold the folded absorbent article (40) adjacent the longitudinal sides. The absorbent article (40) can then be placed in the vestibule (42) by the wearer applying a force with one or more fingers located in the indentation (92) formed by the folded absorbent article. form.

At least one installation and removal tab (94) suitable for use with the absorbent articles described herein extends outwardly from at least one longitudinal side of the absorbent article (40). When assuming that one such flap (94) is effective in placing and removing an absorbent article (40) such as a labial pad, it can be considered that at least two flaps (94 and 94'), one from Extending flaps on each longitudinal side (80, 82) of the absorbent article are also effective in placing and removing the absorbent article. Therefore, in the following discussion, unless otherwise indicated, the absorbent article (40) will have at least two flaps (94 and 94'). While the two fins (94, 94') need not be identical, or more correctly, one is a mirror image of the other, ideally they are. Thus, the description of the first flap will be the description of any other flap. Therefore, for the sake of clarity, the description of any other fins will be omitted. Corresponding parts are indicated in the figures with reference numerals and basic reference numerals. Furthermore, while various types of absorbent articles (40) are shown herein disclosed, it should be understood that the flaps (94, 94') may be incorporated into a number of other suitable shapes and sizes of labial pads.

The phrase "integrally formed" means that the flap (94) is not attached to the absorbent article (40), but acts as the cover (62), barrier (64), and/or absorbent (66), cover and barrier layer, cover layer and absorbent body, or an extension of barrier layer and absorbent body.

The flap (94) has a length (1) measured along a line substantially parallel to the longitudinal axis (L) of the absorbent article (40), and a length (1) along a line substantially parallel to the transverse axis (L) of the absorbent article (40). T) the width (w) of the line measurement. The flaps (94) are of sufficient size to assist a female user in placing the absorbent article (40) in the vestibule (42) and to assist a female user in freeing the absorbent article (40) from the vestibule (42) take out. The phrase "sufficient size" means that the tab (94) can be grasped between the index finger and thumb, or, if there are two tabs, it can be grasped between the index finger and thumb and the middle finger and index finger. Typically, the length (1) of the flap (94) is not greater than the maximum length (L _max ) of the absorbent body (66). More specifically, typically, the length (1) of the tab (94) is no greater than about 100mm; alternatively no greater than about 90mm; alternatively no greater than about 80mm; optionally no greater than about 70mm; Not greater than about 60 mm; alternatively not greater than about 50 mm; alternatively not greater than about 40 mm; alternatively not greater than about 30 mm; alternatively not greater than about 20 mm; greater than about 5 mm.

Typically, the length (1) of the fins (94) is not less than about 1 mm; alternatively not less than about 5 mm; alternatively not less than about 10 mm; alternatively not less than about 20 mm; alternatively not less than about 30 mm; Alternatively not less than about 40 mm; alternatively not less than about 50 mm; alternatively not less than about 60 mm; alternatively not less than about 70 mm; alternatively not less than about 80 mm; One skilled in the art will readily understand that the length (1) of the flaps (94) may also vary according to the general configuration and intended placement of the absorbent article within the female user's vestibule (42).

The tab (94) has a width (w) in addition to a length (1). Typically, the width (w) of the tab (94) is no greater than about 50 mm; optionally no greater than about 40 mm; optionally no greater than about 30 mm; optionally no greater than about 20 mm; optionally no greater than about 10 mm; Optionally no greater than about 7.5 mm; alternatively no greater than about 5 mm; alternatively no greater than about 2.5 mm; or alternatively no greater than about 1 mm.

Materials used in the barrier layer (64) and/or absorber (66). Ideally, any such material minimizes the likelihood of irritation and/or discomfort to the wearer of the absorbent article (40).

The flaps (94) of the present invention may be placed in various positions along the longitudinal sides (80, 82) of the absorbent article (40). For the absorbent articles (40) described herein, a flap (94) may be positioned at any of the first end region (70), the second end region (72) or the middle region (74). Also the second tab (94) may be positioned along the opposite longitudinal sides (80, 82) at either the first end region (70), the second end region (72) or the intermediate region (74). Generally, when a fin (94) extends outwardly from a longitudinal side (80, 82) of a particular region (70, 72, 74), typically any second fin (94') Opposite longitudinal sides (80, 82) of (70, 72, 74) extend outwardly. It should be noted that depending on the length (1) of the flap (94), the flap may cover more than one area (70, 72, 74) as described herein. The flaps (94, 94') described herein provide the opportunity for the female wearer to grasp the flaps to help place the labial pads into the vestibule. In addition, the tabs (94, 94') provide the female wearer with the opportunity to grasp the tabs to aid in the removal of the labial pads and the potential for the female wearer's fingers to contact the body-facing surface of the labial pads which may become soiled sexual minimization.

Although the cover layer (62) and barrier layer (64) in Figure 21 are integrally formed, each flap (94, 94') has a flap absorber (96, 96'). Typically, the material of the flap absorber (96, 96') is similar to the material of the absorber (66). Typically, the presence of absorbent material in the flaps increases the absorbent capacity of the absorbent article.
