Describe in detail

Referring to Fig. 1, show an absorbent article 10, it is placed on the crotch area of contiguous human body 12.This absorbent article 10 can be the absorption product of sanitary towel, menopad, women's pad, pantiliner, trousers shielding part, incontinence clothing or some other type.For the purpose of discussing, will be described as a sanitary towel to this absorbent article 10.This sanitary towel 10 is designed to be dressed by the women, is used for absorbing body fluid, particularly menstrual fluid and the urine of discharging.In Fig. 1, show the side view of human body 12, it includes the trunk 14 of waist 16 and is positioned at the crotch area 18 of the lower end of trunk.Article two, thigh 20 is dangled downwards by crotch area 18, there is shown wherein one leg.Underwear 22 remains on pudendum or vaginal orifice zone near the women to this absorbent article 10.This underwear 22 is underpants typically, and it has a waist opening, two leg openings and the crotch part between two leg openings.The edge of this crotch part or seam 24 are positioned on the relative side of crotch part.These edges or seam 24 stretch round each leg opening.When upwards drawing this underwear 22 round trunk 14, and when regulating about waist 16, the part of edge or seam 24 contacts with wearer's groin usually.Act on underwear 22 and produce an active force that makes progress at the edge or the active force on the seam 24 of crotch area 18, this active force makes edge or seam 24 maintenances and wearer's Body contact.

Referring to Fig. 2, sanitary towel 10 comprises first groove or passage 26 and second groove or passage 28, they two all in the downside of this sanitary towel, form.Two edges 24 of the leg opening of underwear 22 being designed to enter respectively and/or engaging with first and

second passages

26 and 28. also there is the first end 30 of the leading portion that is positioned at contiguous this sanitary towel 10 in sanitary towel 10 and is positioned at the relative end or the rearward end 32 of the back segment of contiguous this sanitary towel 10.First and second ends 30 and 32 lay respectively at the distance that the central point 34 that leaves this sanitary towel 10 equates.The position of this central point 34 is at the intersection point place of the axis x-x of longitudinal center with vertical central axis z-z.If be ready, can make groove or

passage

26 and 28 with respect to this central point biasing.

Should be noted that in use, this sanitary towel 10 can be along the vertical central axis z of health ₁-z ₁Centering, as shown in FIG. 1, perhaps, its position can be at vertical central axis z ₁-z ₁Front portion or rear portion, this depends on wearer's special requirement.Should be noted that also though this sanitary towel 10 of drawing is being symmetric in shape, first and second ends 30 and 32 are left central point 34 distances respectively and equated,, also can form asymmetric sanitary towel, its shape is changed by end to end.

Referring to Fig. 3, this figure illustrates in greater detail this sanitary towel 10.This sanitary towel 10 comprises cover layer 36 and liquid-tight barrier layer 38 of a transflective liquid, and their cooperations are to wrap an absorber 40.Can make cover layer 36 by natural material or synthetic material, this layer should be penetrated such as menstrual fluid, blood, urine etc. by body fluid easily.The suitable material of this cover layer 36 comprises the material that those have soft feel, such as the polyolefin spunbonded material by Kimberly-Clark company produce and market.This cover layer 36 also can be by a kind of bonding shipment paper web, and the fiber of polyester, polypropylene, polyethylene, nylon or other similar type is made.Also can use other polyolefin, such as the linea low density polypropylene, linear low density polyethylene has the film web lining of pore and Web materials.If the use thermoplastic film must perforate, perforation or it is separated, make liquid to see through.

Liquid-tight barrier layer 38 is designed to prevent that the liquid that leaves sanitary towel 10 from passing through.Yet, can make the wet steam that makes or allow air and leave sanitary towel 10 to the structure on this barrier layer 38 and pass through, be used for stoping fluid or liquid to pass through simultaneously by it.This barrier layer 38 also can be the microporous membrane that can see through air, and it will prevent that liquid from therefrom flowing through.This barrier layer 38 can be a kind of foams, for example, and polyolefin foam or polyurethane foam.Polyolefin foam can be made by polyethylene or polypropylene.This barrier layer 38 also can be to make its liquid-tight foams that see through liquid make by processed or coating.Best, this barrier layer 38 is made by extremely thin thermoplastic film, and this thin film has less than about 2 millimeters thickness, preferably less than about 1 millimeter.Using good two kinds of thermoplastic films is polyethylene and polypropylene.Can be painted these thin film, or they are made into a kind of special color, such as rose-colored or peachiness, make that this sanitary towel 10 is more attractive.

Still referring to Fig. 3, will be noted that, bonding or be sealed cover layer 36 and barrier layer 38, form an edge joint 42.This edge joint 42 stretches round absorber 40 fully, and this absorber 40 is surrounded.If be ready, can form a kind of form that is called as wound gasket, wherein, the lower surface of the contiguous absorber 40 in the position on barrier layer 38, and cover layer 36 is holding absorber 40 and barrier layer 38 fully.Subsequently, along the lower surface of sanitary towel 10, cover layer 36 is bonded to or is fixed on himself.Person skilled in the art scholar knows the various alternate manners on assembling cover layer, absorber and barrier layer, and various alternative can be used for the present invention.

Absorber 40 is between cover layer 36 and barrier layer 38.The side 46 that absorber 40 has first side 44 and second of stretching in the vertical to stretch in the vertical.Absorber 40 also has first end 48 and the second end 50, and they illustrate with dotted line in Fig. 2.Absorber 40 also has a body-facing surface 52 and towards the health of the surface of clothes 54. body-facing surface 52 towards the wearer of this sanitary towel 10, but, it not necessarily with Body contact, though it can with Body contact. the body-facing surface 52 of absorber 40 is covered by cover layer 36 usually.Absorber 40 towards the surface 54 of clothes towards underwear 22, still, it not necessarily contacts with underwear 22.Surface 54 towards clothes is covered by barrier layer 36 usually, though must be not like this.

For the purpose of discussing, absorber 40 is described as single absorbed layer.Yet, should be noted that, can make one or more absorbed layers to absorber 40, or with scatter one or more layers the combination of a kind of superabsorbent material. absorber 40 can be made by natural fiber or synthetic fibers, is perhaps made by their mixture.Natural fiber comprises cellulose fibre, such as Pilus Caprae seu Ovis, Cotton Gossypii or regenerated cellulose.Synthetic fibers can comprise polyester or polyolefin, and serve as preferred with polyethylene and polypropylene fibre.Absorber 40 also can be made by being total to moulding material, and this material is the mixture of wood pulp fluff and synthetic meltblown fibers.When adopting synthetic fibers, can handle these fibers with a kind of surfactant, thereby improve their wettability.

Absorber 40 also can comprise a kind of hydrocolloid material, usually it is called super absorber.Usually super absorber is added in the absorber,, also improve the fluid hold facility to increase the fluidic quantity that absorber can comprise.Can be used as independent granule and add super absorber, perhaps, can make laminar structure to it, have to be combined in a superabsorbent material that carries on the thin slice.

Still referring to Fig. 3, will be noted that, in a lower surface of absorber 40, form first and second grooves or

passage

26 and 28 respectively, and the shape of first and

second passages

26 and 28 is agreed on barrier layer 38 respectively. this is arranged so that first and

second passages

26 and 28 are respectively can be observable in final products.Also can form first and

second passages

26 and 28 respectively in the lower surface of sanitary towel 10, subsequently,

transversal passage

26 and 28 stretches or bridge joint barrier layers 38.When doing like this, the shape of

passage

26 and 28 will not be agreed on barrier layer 38.The joint of the edge of underwear 22 or seam 24 will make barrier layer 38 stretch, and force them to enter first and

second passages

26 and 28 respectively.Best, barrier layer 38 made make it enter respectively in first and

second passages

26 and 28, and when sanitary towel 10 is ready to use, this first and

second passage

26 and 28 will be can be observable for last user.Particularly for sanitary towel, normally each sanitary towel is surrounded holding on the device of it individually, keeping it is cleaning and health.This holds device and can be made by thermoplastic, such as polyethylene or polypropylene.

Referring now to Fig. 4-8,, show several embodiment, with 28 different settings, size and configuration are shown for first and second passages 26 respectively.Just for simply, only to show absorber 40 in the surface 54 of clothes, forming first and

second passages

26 and 28 respectively.For the purpose of discussing, in all Fig. 4-8, use

identical label

44 and 46 respectively for the side of stretching in the vertical of absorber 40, and to towards health with use

identical label

52 and 54 respectively towards the surface of clothes.Unique difference will be the label difference that is used for representing passage.

In Fig. 4, absorber 40 comprises first groove or passage 26 ' and second groove or passage 28 '.In first and second passages 26 ' and 28 ' each comprises base 58 and angled side walls 60 of a vertical sidewall 56, a level respectively.In the sloped sidewall 60 each is stretched over surface 54 towards clothes by horizontal base 58.Angled side walls 60 is aimed at the most close x-x of central axis longitudinally, and vertical sidewall 56 is positioned at the outside, and contiguous corresponding first and

second sides

44 and 46 longitudinally.Two passages 26 ' and 28 ' separated from each other, and each passage is positioned on the relative side of central axis x-x longitudinally.First and second passages 26 ' and 28 ' can be respectively collinear or non-directional.Best, first and second passages 26 ' and 28 ' difference are parallel to each other, perhaps, if about central axis x-x longitudinally is non-directional, preferably each other for mirror image. first and second passages 26 ' and 28 ' the degree of depth (d) correspondingly can change, but preferably be about 0.1 inch (about 2.5 millimeters) at least, the most preferably by about 0.1 inch to about 0.5 inch (about 2.5 millimeters to about 13 millimeters).Because the thickness of absorber 40 (t) can be along the longitudinal central axis x-x change, the another way that the degree of depth (d) of each in first and second passages 26 ' and 28 ' is described is respectively that the scope of the degree of depth (d) of passage 26 ' and 28 ' can be by about 10% to about 90% of the thickness (t) of absorber 40.Best, the scope of the passage 26 ' and 28 ' the degree of depth (d) will be by about 10% to about 75% of the thickness (t) of absorber 40, preferable, the scope of the passage 26 ' and 28 ' the degree of depth (d) will be by about 20% to about 50% of the thickness (t) of absorber 40.The most desirable, the scope of the passage 26 ' and 28 ' the degree of depth (d) will be by about 25% to about 50% of the thickness (t) of absorber 40.

Should be noted that, when absorber 40 when forming more than one deck, first and second passages 26 ' and 28 ' the degree of depth (d) be respectively absorber 40 an ad-hoc location the certain percentage of thickness (t).Also should be noted that, when absorber 40 being made protuberance having central axis x-x along the longitudinal or it is configured to certain form, absorber 40 has that part of of first and second passages 26 ' and 28 ' that the thickness littler than the maximum ga(u)ge of absorber 40 (t) can be arranged respectively.

Referring now to Fig. 5,, the figure shows the another kind of configuration of first and second passages.Absorber 40 comprises first groove or passage 26 ＂ and second groove or passage 28 ＂.First and second passages, 26 ＂ and 28 ＂ are respectively the semi-circular shape of turning around, its radius ＂ r ＂ is approximately 0.01 inch (about 0.25 millimeter) at least, and radius ＂ r ＂ is preferably by about 0.01 inch to about 0.25 inch (about 0.25 millimeter to about 6.4 millimeters).First and second passages, 26 ＂ and 28 ＂ can be respectively collinear or non-directional.First and second passages, 26 ＂ and 28 ＂ can stretch along the part of the length of absorber 40, and perhaps they can be along the whole length extending of absorber 40.

Referring to Fig. 6, the figure shows another configuration of first and second passages.Thin absorber 40 has first groove or passage 26 ＂ ' and second groove or passage 28 ＂ ' that form therein respectively.First and second passages, 26 ＂ ' and 28 ＂ ' are respectively the form of the U word that turns around, and it is darker than shown in Figure 5 that this U word stretches absorber 40 into.For example, the degree of depth (d) of first and second passages, 26 ＂ ' and 28 ＂ ' can be respectively by about 50% to about 95% of the thickness (t) of absorber 40.Best, the degree of depth (d) of first and second passages, 26 ＂ ' and 28 ＂ ' can be respectively by about 70% to about 95% of the thickness (t) of absorber 40, the most desirable, the scope of the degree of depth (d) of first and second passages, 26 ＂ ' and 28 ＂ ' can be by about 70% to about 90% of the thickness (t) of absorber 40.First and second passages, 26 ＂ ' and 28 ＂ ' can be respectively collinear or non-directional.First and second passages, 26 ＂ and 28 ＂ can be respectively stretch along the part of the length of absorber 40, and perhaps they can be along the whole length extending of absorber 40.The length of first and second passages, 26 ＂ ' and 28 ＂ ' can stretch certain distance respectively, this distance be absorber 40 length about 25% to about 100%.Best, the length of first and second passages, 26 ＂ ' and 28 ＂ ' stretches about 25% to about 75% distance by the length of absorber 40 respectively, and is the most desirable, stretches about 30% to about 70% distance of the length of absorber 40.Should be noted that when sanitary towel 10 has periphery to seal 42, the whole length of sanitary towel 10 or whole length will be bigger than the whole length of absorber 40.

Referring to Fig. 7, this thin absorber 40 that illustrates has much bigger whole width.Absorber 40 what form in the surface 54 of clothes is first groove or passage 27 and second groove or passage 29, they two all be the configuration of inverted v-shaped.The degree of depth of this V word configuration can stretch inwards the amount of absorber 40 into be absorber 40 gross thickness (t) about 10% to about 90%.Best, the recess of this V font will stretch inwards the amount of absorber 40 into be absorber 40 gross thickness (t) about 20% to about 75%, the most desirable, about 25% corresponding with first and

second passages

26 and 28,26 ' and 28 ' and 26 ＂ ' and 28 ＂ ' respectively on their function with 29 for the thickness (t) of absorber 40 to about 50%. first and second passages 27.When first and second passages 27 and 29 when being respectively collinear, they can be to leave about at least 0.25 inch (about 6.4 millimeters) inwards by first and

second sides

44 and 46 of stretching in the vertical respectively.Best, first and second passages 27 and 29 leave about at least 0.5 inch (about 13 millimeters) inwards by first and

second sides

44 and 46 of stretching in the vertical respectively.When passage 27 and 29 is non-directional, the end of each passage can be stretched over first and

second sides

44 and 46 of stretching in the vertical respectively.

When comparison diagram 6 and 7, will be noted that passage 27 and 29 is arranged in the distance of leaving the axis x-x of longitudinal center in Fig. 7 bigger than the distance at Fig. 6.This difference of size may be favourable aspect the different crotch area that adapts to the women, and wherein the variable in distance between groin depends on a people's anatomy.For the consumer of dressing certain type underwear, it also may be favourable dressing such a kind of absorbent article, and this absorbent article makes the lateral edges 24 of underwear 22 cosily to fit into respectively in first and second passages 27 and 29.

Referring to Fig. 8, show an embodiment of absorber 40, wherein absorber has the surface of ribbon line, and central axis x-x is thicker along the longitudinal on this surface, and contiguous first and

second sides

44 and 46 of stretching in the vertical are thinner respectively.In this embodiment, first and second passages 27 ' and 29 ' have respectively and first and second passages 26 ' and 28 ' the similar configuration that illustrate respectively in Fig. 4.Yet first and second passages 27 ' and 29 ' lay respectively at the thin perimeter of absorber 40.Will notice once more that to leave the distance of the axis x-x of longitudinal center respectively bigger than the distance of first and second passages 26 ' that illustrate respectively and 28 ' for first and second passages 27 ' and 29 ' in Fig. 8 in Fig. 4.Expectation will make the width of sanitary towel 10 make when the lateral edges 24 of underwear 22 contacts with sanitary towel 10 with the size that makes first and second passages 27 ' and 29 ' position respectively, needn't change the crotch area 18 of underwear 22 significantly.In addition, should make first and second passages 27 ' make them will force absorber 40 to contact with the groin of user with 29 ' position.

Also should be noted that, can in the lower surface 54 of absorber 40, be formed on first and

second passages

26 and 28,26 ' and 28 ', 26 ＂ ' and 28 ＂ ', 27 and 29 and 27 ' and 29 ' in many different modes.Can use a cutter or rotary cutter in absorber, to cut out these passages, perhaps, can advance they mold pressings in the absorber.Also can produce these passages, thereby after absorbing material is full of this mould, these passages will occur by the protuberance that in a mould, forms two risings of separating.These passages also can form by the alternate manner that persons skilled in the art know. and forming passage by mold pressing may be the easiest realization. and mold process is favourable, is to form two passages simultaneously.

Referring to Fig. 9, the sanitary towel 10 that illustrates is positioned at contiguous wearer's crotch area 18.Underwear 22 remains on its position to sanitary towel 10.The lateral edges 24 of underwear 22 contacts with 28 ＂ with passage 26 ＂, and among admission passage 26 ＂ and 28 ＂, thereby force sanitary towel 10 upwards to be pressed against on wearer's the health, and be fixed on wearer's the health.To move up sanitary towel 10, up to first and second longitudinally side 44 with 46 respectively with till wearer's groin contacts.In Fig. 9, will be noted that, show thigh 20, thereby show the normal position of sanitary towel 10 when being positioned at contiguous health.In the process of the proper motion of trunk 14 and lower limb 20, such as walk, stand, sit down, running etc., thigh may move to and relatively be close together, sanitary towel 10 may be extruded.Yet the active force that acts on the leg opening of underwear 22 will make lateral edges 24 keep sanitary towels 10 to be fixed on the health.

Referring to Figure 10, there is an absorber 40 of wider width in the sanitary towel 10 that illustrates, as illustrated in Figure 6.Because absorber 40 will be noted that than wide at the absorber shown in Fig. 9, this absorber 40 first and second

longitudinally side

44 and 46 will stretch downwards by inguinal region respectively, and the leakage of convection cell provides additional protection.Underwear 22 with respect to the function of sanitary towel 10 with in the above about Fig. 9 describe identical.Should be noted that, in Fig. 9 and 10, cover layer 36 and barrier layer 38 are removed, only just for simple purpose.If sanitary towel 10 comprises a cover layer 36, comprise barrier layer 38 again, they two will exist in actual use.

Turn to Figure 11-12 now, these illustrate

passage

26 and 28 multiple different setting.For the purpose of understanding, all article all will be considered as sanitary towel 10, and they have an absorber 40, and first and second grooves or

passage

26 and 28 are arranged respectively.When existing, will use additional label for these additional passages more than two passages.

In Figure 12, show the bottom view of sanitary towel 10, it has a pair of

passage

26 and 28 that stretches in the vertical, and they are arranged to be parallel to first and

second sides

44 and 46 longitudinally respectively.First and

second passages

26 and 28 are respectively collinear, and, on the whole length of absorber 40, do not stretch.But the first button

second channel

26 and 28 stretches a quite long length respectively, by about 50% to about 90% of the total length of absorber 40.Best, first and

second passages

26 and 28 stretch respectively by the total length of absorber 40 about 60% to about 80%, the most desirable, stretch by about 70% to about 75% of the total length of absorber 40.The reason that first and

second passages

26 and 28 do not stretch on the whole length of absorber 40 respectively is, the basal surface of sanitary towel 10 will be a convexity with respect to health, therefore, the core of sanitary towel 10 is actually important zone, in this zone, the lateral edges 24 of underwear 22 must enter first and

second passages

26 and 28 respectively.

There are an axis x-x of longitudinal center and a central transverse axis y-y in shown sanitary towel 10.Can make first and second passages 26 and 28 in the lower surface 54 that enters absorber 40 respectively, make them outwards stretch an equal quantity by central transverse axis y-y in the vertical.In addition, they can leave the distance that the axis x-x of longitudinal center equates.Also have, each in first and second passages 26 and 28 is left about at least 0.25 inch (about 6.4 millimeters) inwards, and is best, leaves first and second about at least 0.5 inch of the sides 44 and 46 (about 13 millimeters) of stretching in the vertical separately respectively.Also can be arranged to first and second passages 26 and 28 parallel to each other respectively.First and second passages 26 and 28 will have the width of about 0.1 inch (about 2.5 millimeters) to about 0.5 inch (about 13 millimeters) respectively, the degree of depth of about 0.1 inch (about 2.5 millimeters) to about 0.5 inch (about 13 millimeters), and the length of about at least 3 inches (about 7.6 millimeters).Best, first and second passages 26 and 28 length are respectively by about 3 inches (the about 7.6 millimeters) distance to the length that equals sanitary towel 10.The most desirable, first and second passages 26 and 28 length respectively by about 3.5 inches (about 8.9 millimeters) to about 4.5 inches (about 11.4 millimeters).

Referring to Figure 12, an enforcement of the sanitary towel 10 that illustrates has the

side

44 and 46 of inclination.The

side

44 and 46 that tilts makes sanitary towel 10 that an asymmetrical shape be arranged, make its front end 30 wideer than relative end or rear end 32. in the lower surface 54 of absorber 40, form first and

second passages

26 and 28 respectively, and it is they are arranged to have each other an angle, thereby parallel with the side 44 that tilts respectively with 46.As among Figure 11, first and

second passages

26 and 28 do not stretch on the whole length of absorber 40 respectively, but only stretch along the sizable part of its one.The sizable part ＂ of ＂ is meaning than 50% of the total length of absorber 40 big quantity.

Referring to Figure 13, show the sanitary towel 10 of hourglass shape.This sanitary towel 10 has first and

second passages

26 and 28 respectively, and they are non-directional, and shape is preferably arcual.First and

second sides

44 and 46 of stretching in the vertical are respectively non-directional, and each in first and

second passages

26 and 28 is parallel with 46 with these non-directional sides 44 respectively.Also can be arranged so that first and

second passages

26 and 28 respectively with respect to central axis x-x longitudinally and be mirror image each other.The sanitary towel 10 of hourglass shape is preferred for the situation of less absorbing material is arranged at the center of crotch area at central axis y-y transversely, and when dressing, this produces a kind of more comfortable sanitary towel.First and

second passages

26 and 28 do not stretch on the whole length of absorbent article 10 respectively.As top about Figure 11 and 12 described, first and

second passages

26 and 28 can be respectively along a sizable length extending of sanitary towel 10.The sizable length ＂ of ＂ is meaning than 50% of the length of absorber 40 big quantity.

Referring to Figure 14-16, will be noted that these sanitary towels are respectively with corresponding at shown in Figure 11,12 and 13 those.Unique difference is that first and second grooves or

passage

26 and 28 stretch respectively basically on the whole length of absorber 40.The concrete configuration that depends on each sanitary towel, the whole basically length ＂ of ＂ meaning absorber 40 length about 90% to about 100%.First and

second passages

26 and 28 reasons that may not be stretched over the whole length of absorbent article 10 respectively are that the end of sanitary towel 10 may be a rounding, and first and

second passages

26 and 28 shape may be respectively arcual.Therefore, it may be difficult first and

second passages

26 and 28 being made the top that makes them be stretched over the rounded portion of absorber 40 respectively.

In Figure 14 and 15, will be noted that first and

second passages

26 and 28 are respectively collinear, and, they are arranged to be parallel to respectively the

side

44 and 46 of stretching in the vertical.And in Figure 16, first and

second passages

26 and 28 are respectively non-directional, and they are parallel to

non-directional side

44 and 46 of stretching in the vertical respectively.

Turn to Figure 17-19 now, will be noted that, similar with shown in Figure 14-16 of sanitary towel 10, difference is that first and second grooves or passage 26 are different respectively with 28 configuration.In Figure 17, first and

second passages

26 and 28 configuration are respectively non-directional.Best, first and

second passages

26 and 28 have arcual shape respectively, and are therefore, not parallel with the

side

44 and 46 of stretching in the vertical respectively.In Figure 18, first and

second passages

26 and 28 design also are respectively arcual, and, not parallel with the

side

44 and 46 of stretching in the vertical that tilts respectively.In Figure 19, first and

second passages

26 and 28 are respectively collinear, therefore, and respectively can not be parallel with 46 with the side 44 of hourglass shape.Will be noted that in Figure 17-19, first and

second passages

26 and 28 stretch respectively basically on the whole length of absorber 40.

Referring to Figure 20-22, show three embodiment, wherein, each sanitary towel 10 is included in a plurality of passages that form of absorber 40 in the surface 54 of clothes.In Figure 20, form two pairs of

passages

62 and 64, and 66 and 68, they have arcual shape, and they are arranged so that first and

second passages

62 and 64 are much smaller, and, leaving than first and

second passages

66 and 68 respectively that central axis x-x is farther longitudinally. and first and

second passages

66 and 68 have respectively than first and

second passages

62 and 64 longer total lengths.If be ready, can two pairs of

passages

62 and 64,66 and 68 be set symmetrically about axis x-x of longitudinal center and central transverse axis y-y.

Referring to Figure 21, will be noted that there are two pairs of first and second passages that form at absorber 40 in sanitary towel 10 in the surface 54 of clothes.The first pair of

passage

62 and 64 configuration are collinear, and stretch on the whole length of absorber 40 basically.The first pair of

passage

62 and 64 is positioned at and leaves the axis x-x of longitudinal center than second pair of

passage

66 and 68 farther distances.The second pair of

passage

66 and 68 also is collinear, and along the whole length extending of absorber 40. because the end of the rounding of sanitary towel 10, the length than first pair of

passage

62 and 64 is a little long a little for the second pair of

passage

66 and 68 total length.If be ready, can be arranged to all passages parallel to each otherly, and be parallel in the vertical the

side

44 and 46 of stretching respectively.The benefit that a plurality of passages are set at the lower surface 54 of absorber 40 is that sanitary towel 10 can use with the underwear 22 of the crotch area 18 that different in width is arranged.Some underwear 22 has narrower crotch area 18.By in absorber 40, forming two pairs or many, can use sanitary towel 10 with the multiple underwear 22 of the crotch area 18 that different in width is arranged to passage.Equally, some consumer may find, it is more favourable that the position at the edge 24 of underwear 22 is aimed at their crotch area, and other people may be ready more that the edge 24 of underwear 22 is positioned at the center of the axis x-x of longitudinal center of more close sanitary towel 10.

Referring to Figure 22, there are three pairs of

passages

62 and 64,66 and 68 in the sanitary towel 10 that illustrates, and 70 and 72, form these passages at the lower surface of absorber 40 or in the surface 54 of clothes.The shape of three pairs of passages all is arcual, and, on the length with respect to they position changes on absorbent article 10.First pair of

arcual passage

62 and 64 has the shortest length, and, be positioned at the outmost edge of sanitary towel 10.The second pair of

passage

66 and 68 is positioned at the inside of first pair of

passage

62 and 64, and longer a little length is arranged.The 3rd pair of passage 70 and 72 has the longest length, and lays respectively at the inside of first and second pairs of

passages

62 and 64,66 and 68.As the illustrated mistake in front, form a plurality of passages at the lower surface of absorber 40 and provide alternative for final user.This also makes final user can use this sanitary towel 10 with the multiple underwear of the crotch area that different in width is arranged.

Referring to Figure 23 and 24, the absorbent article 74 that illustrates has a surface 76 with Body contact, and it has first side 78 that stretches in the vertical that raises and second side 80 that stretches in the vertical that raises.Absorbent article also has first end 82 and the second end 84.As being clear that among Figure 24, absorbent article 74 comprises cover layer 86 and liquid-tight barrier layer 88 of a transflective liquid, and their cooperations surround an absorber 90.Cover layer 86, barrier layer 88 and absorber 90 are made an absorption pad 92.Upper surface or with the surface 76 of Body contact on form first and

second sides

78 and 80 that stretch in the vertical that raise respectively.The

side

78 and 80 that stretches in the vertical of each rising has the outer surface 94 and 96 of an in the vertical direction orientation respectively.＂ in the vertical direction orientation ＂ is meaning outer surface 94 can be parallel with center vertical axis z-z with 96, perhaps to become an acute angle with it.Should be noted that vertical outer surface 94 and 96 can be collinear or non-directional.When being non-directional, their configuration can be bending or arcual.Pad 92 also can have a surface 98 towards clothes, with body-facing surface 76 vis-a-vis.Surface 98 towards clothes is designed to interior crotch area towards underwear.

In Figure 24, will be noted that cover layer 86 and barrier layer 88 100 and 102 are linked together in the position respectively, and these positions are positioned on the surface 98 of clothes.Yet,, can carry out being connected along vertical outer surface 94 and 96 if be ready.In addition, if be ready, can wrap barrier layer 88 and absorber 90 fully with cover layer 86.

This absorbent article 74 also comprises a pair of

flap

104 and 106, and they have enough sizes, and the part round the crotch area of underwear stretches at least.Best,

flap

104 and 106 will be piled up, and be joined to one another.In addition, can be connected to

flap

104 and 106 or be fixed on the outer surface of crotch part of underwear.Each

flap

104 and 106 has a

proximal edge

108 and 110 respectively, and a

remote edge

112 and 114 are arranged respectively.One of each

proximal edge

108 and 110 is connected respectively in the outer surface 94 and 96 that is vertically oriented.Each

remote edge

112 and 114 crotch parts round underwear stretch downwards and inwards.A bit be important below noticing,

flap

104 and 106 be not designed to stretch upwards in the crotch area of user into that this is because the

side

78 and 80 that stretches in the vertical that raises will play this function respectively.On the contrary, this also dangles downwards inwards to

flap

104 and 106 crotch parts round contiguous underwear, may be by the humoral pollution of absorbent article 74 leakages thereby clothing is any in preventing.

Can be made into any size and dimension of wanting to this to flap 104 and 106, if they transversely central axis y-y enough width are arranged, when they when underwear is reeled, be enough to be piled up.Yet, in order to obtain best effect, should make flap 106 and 108 be positioned at the center of absorbent article 74, make them divide fork central transverse axis y-y.More following also is favourable, flap 104 and 106 is made make them have respectively along remote edge 112 and 114 length measured L ₁, this length ratio is respectively at proximal edge 108 and 110 length measured L ₂Long.Each flap 104 and 106 length L ₁Can between about 2.5 inches to about 5 inches (about 6.4 millimeters to about 12.7 millimeters), change, and length L ₂Can between about 1 inch to about 2.5 inches (about 2.5 millimeters to about 6.4 millimeters), change.In order to obtain best effect, ratio L ₂/ L ₁Should be between about 50% to about 80%, best, ratio L ₂/ L ₁Should be between about 60% to about 80%, and the most preferably, ratio L ₂/ L ₁Should be between about 70% to about 75%.When using these ratios, will obtain an absorbent article 74, wherein, the optics impression in observer's eye will be that in fact the full-size(d) than them is big to flap 104 and 106.This is favourable, because this makes the producer can use minimum material, and consumer feels that this is bigger to flap 104 and 106, and therefore the pollution to underwear provides better protection.

Still referring to Figure 23 and 24, each

flap

104 and 106 comprises an erecting

device

114 and 116, is used for this fixed to one another to flap 104 and 106.In Figure 23 and 24, the erecting device 116 that illustrates is a slice adhesivess that are positioned on the outer surface of flap 106, and erecting device 118 is a slice adhesivess that are positioned on the inner surface of flap 106.Flap 104 is designed at first folding round underwear, second flap 106 is designed to folding round underwear subsequently, make adhesives 118 to contact with adhesives 116, and, can firmly fix to

flap

104 and 106 this about underwear.Also can make

flap

104 and 106 shorter, make them not overlapping, but erecting

device

116 and 118 is designed to directly be installed on the outer surface of underwear, when

flap

104 and 106 was installed on the underwear, erecting

device

116 and 118 was positioned on the inner surface of each flap 104 and 106.Except using adhesives, erecting

device

116 and 118 can be a mechanical fixed part, such as the fixture of shackle type.VELCRO ^TMIt is one type hook-and-loop.＂ VELCO ＂ is the registered trade mark of Velcro u s company, and the said firm is at 406 Brown Ave., Manchester, and NH 03103 has office.The fixture of other form comprises the material that will be bonded to each other.For example, can be formed the part of whole flap or each

flap

104 and 106 respectively by a kind of material, this kind material will bond on the another kind of material.Adherent adhesives will make two

flaps

104 and 106 be bonded to each other, but still can throw off.Also have, can use snap-fastener and one to connect mechanical mechanism by button hole, hasp or certain type, this that

flap

104 and 106 is kept together.The present invention has imagined the erecting device of all these types and other content known to the persons skilled in the art.

Absorbent article 74 also comprises first and

second passages

120 and 122, and they form in the surface 98 of clothes pad 92.Respectively the size of first and

second passages

120 and 122 and configuration are made with the lateral edges of underwear and cooperated.A kind of typical underwear comprises a waist opening and two leg openings, has a crotch part between two leg openings.This crotch part generally includes a lateral edges or seam, and this lateral edges or seam are successive about the periphery of each leg opening.Two lateral edges or joint designs are become, when the trunk about consumer upwards draws this underwear, contact with 122 with first and second passages 120 respectively.When making underwear be positioned at its position, lateral edges will enter first and

second passages

120 and 122 respectively, and, absorbent article 74 is firmly held on the health.By absorbent article 74 is remained near health or and Body contact, the amount that can make the leak fluid that may occur is minimum.This is very favorable, because if the body fluid of falling in the absorber 90 is not to compile on cover layer 86, the probability that can reduce leakage significantly occurs.

Refer again to Figure 23, will be noted that, first and

second sides

78 and 80 that stretch in the vertical that raise do not stretch on the whole length of absorbent article 74 respectively.On the contrary, first and

second sides

78 and 80 that stretch in the vertical that raise stretch along a significant part of the length of absorbent article 74 respectively.A significant part ＂ of ＂ length meaning the length that stretches be absorbent article 74 length about 50% to about 95% between.Best, the length that first and

second sides

78 and 80 that stretch in the vertical stretch respectively be absorbent article 74 length about 60% to about 80% between.

Forward Figure 24 once more to, first and second sides 78 that stretch in the vertical and 80 outer surface 94 and 96 have height H respectively ₁, this highly can change by about 2 millimeters to about 25 millimeters.Best, height H ₁At least be approximately 0.2 inch (about 5 millimeters), preferable is to be approximately 0.25 inch (about 6.4 millimeters).For thicker absorbent article 74, this height H ₁Should be about 0.5 inch (about 12.7 millimeters).The

side

78 and 80 that stretches in the vertical of each rising has the height H of a inside respectively ₂, tolerance of this height by the summit of each

side

78 and 80 to the surface 76 of Body contact.This height H ₂Compare H ₁Little, will be to compare height H usually ₁Few by about 25% to about 75%.Best, this height H ₂Compare H ₁Little by about at least 50%.

Should make first and second sides 78 that stretch in the vertical that raise and 80 height H ₁Size and configuration make respectively at least in part, preferably enter the crotch area of user fully.This will guarantee that

flap

104 and 106 can only be dangled by outer surface 94 and 96 downwards and inwards.Underwear will can upwards not push away these flaps.

Referring now to Figure 25,, the human body that is drawn has trunk 124, and two thighs 126 and 128 that dangled by trunk are arranged.Medial surface in every thigh 126 and 128 is groin 130 and 131, and they are formed by separately thigh 126 and 128 connecting portions with trunk 124 respectively.Each groin 130 and 131 comprises a crease 132 and 134 respectively.The crotch part of shown underwear 136 has two lateral edges or seam 138 and 140 respectively, and they form the part of each leg opening in the underwear 136.When trunk 124 upwards draws underwear 136, lateral edges 138 and 140 mates up with them, and is accommodated in these passages or the groove, thereby absorbent article 74 is fixed on groin 130 and 131 in admission passage or groove 120 and 122.The active force that is applied on the lateral edges 138 and 140 of underwear 136 will make first and

second sides

78 and 80 that stretch in the vertical enter crease 132 and 134 respectively, therefore, form a sealing gasket with health.This sealing gasket will be guaranteed to reduce fluidic leakage when dressing this absorbent article 74.

In Figure 25, the absorber 90 that illustrates does not have cover layer 86 and barrier layer 88.Do so only just in order to be clearly shown that the purpose of absorbent article 74.Should make feasible easily enter groin 130 and 131 to the size of first and second sides 78 that stretch in the vertical that raise and 80 and configuration.This is meaning and will be configured to groin 130 and 131 couplings with consumer to the height of first and second sides 78 that stretch in the vertical that raise and 80, wide and length respectively.Lateral separation between first side 78 that raises and second side 80 that raises should make them that in the vertical direction is alignd with crease 132 and 134.Should be noted that first and second sides 78 and 80 that stretch in the vertical that raise are uninevitable respectively to be entered in the crease 132 and 134 of groin 130 and 131 fully, still, should enter at least in part in these creases 132 and 134.Because women's dissection situation difference, first and second sides 78 and 80 that stretch in the vertical that raise respectively configuration do straight for some product may to be favourable, may to be favourable and make non-directional for other products.For example, for straight sided absorbent article 74 shown in Figure 23, it may be favourable doing first and second sides 78 and 80 that stretch in the vertical that raise straight respectively, and in hourglass shape absorbent article, first and second sides 78 and 80 that stretch in the vertical that raise can be respectively non-directional or be shaped as arcual.

When carefully seeing Figure 25, will be noted that, the contiguous absorbent article 74 in the position of underwear 136, and this stretches downwards and inwards

flap

104 and 106, thus overlap each

other.Fixture

116 and 118 is joined to one another this to flap 104 and 106.In this position,

flap

104 and 106 is fully round the crotch parts of underwear 136, and will prevent underwear particularly edge 138 and 140 by humoral pollution.

Referring now to Figure 26,, the absorbent article 74 that illustrates has been removed cover layer 86 and barrier layer 88, thus the

clearer side

78 and 80 that shows the rising that engages with the crease 132 and 134 of groin 130 and 131 respectively.In this embodiment, first and

second passages

120 and 122 lay respectively at and leave the farther position of vertical central axis z-z, make them more can aim at crease 132 and 134 by in the vertical direction.This embodiment makes the edge, distal side 142 and 144 of absorber 90 to be stretched by crease 132 and 134 downwards and with leaving.This downward orientation will make

flap

104 and 106 move towards each other inwards than in the bigger degree shown in Figure 25.Yet as shown in Figure 25,

flap

104 and 106 does not stretch upwards, and only stretches downwards and inwards, thereby is holding and wrapping underwear 136.Should be noted that the distance between

passage

120 and 122 can change, but the distance of about 2 inches to about 4 inches (about 51 millimeters to about 102 millimeters) can be worked well.Preferable distance between the

passage

120 and 122 is between about 2 inches to about 3 inches (about 51 millimeters to about 76 millimeters).

Referring to Figure 27, another embodiment of the absorbent article 146 that illustrates has a kind of hourglass configuration. and this hourglass configuration has first side 148 that stretches in the vertical that raises and second side 150 that stretches in the vertical that raises.In the side 148 and 150 of these risings each is non-directional in appearance.Therefore, first and second sides 148 and 150 that stretch in the vertical that raise are arranged in central transverse axis y-y place respectively are close together, and leaving bigger distance near

end

82 and 84 punishment.In first and second sides 148 and 150 that stretch in the vertical that raise each also stretches on the whole length of absorbent article 146 respectively basically.In a kind of typical hourglass configuration, the side 148 of rising and 150 can have a kind of arc or crooked configuration.

Referring to Figure 28, another embodiment 152 of the absorbent article that illustrates has oval shape.This absorbent article 152 comprises first side 154 that stretches in the vertical that raises and second side 156 that stretches in the vertical that raises.The

side

154 and 156 of these two risings is bending or non-directional on configuration, and the length of stretching, extension is a little shorter a little than the total length of absorbent article 152.First and

second sides

154 and 156 that stretch in the vertical that raise leave morely in central transverse axis y-y punishment respectively, and are being close together near

end

82 and 84 places.First and second sides 148 and 150 that stretch in the vertical that raise, and 154 will make the producer to produce with this difference of 156 size, configuration and position will to adapt to the absorbent article of many different women's anatomical features best.Some women may more like the absorbent article 146 of hourglass shape, and other people may more like oval-shaped article 152, and some more like rectangular absorbent article 74 again.

Referring now to Figure 29-31,, these illustrate three additional embodiment.In Figure 29, the absorbent article 158 that illustrates has been removed cover layer 86 and barrier layer 88, so that clearly show that the underwear 136 of admission passage 120 and 122.Each

passage

120 and 122 has an inwall 160 and 162 respectively, and

flap

164 and 166 is respectively fixed on these inwalls.Each

flap

164 and 166 has a

proximal edge

168 and 170 respectively, and a

remote edge

172 and 174 are arranged respectively.

Proximal edge

168 and 170 is designed to be fixed on the inwall 160 and 162 of each passage 120 and 122.Each

flap

164 and 166 also has an erecting device, such as any or a slice adhesives or mechanical fixed part, they is designed to be fixed on the lower surface of underwear 136.

Flap

164 and 166 does not overlap each other, but their size and configuration are made the downward and stretching, extension inwards round the part of underwear 136, and is directly connected on the underwear.

There is the benefit of a uniqueness of the lip-deep flap 164 that is installed to

passage

120 and 122 and 166 to be, first and

second sides

78 and 80 that stretch in the vertical that raise can enter inguinal crease, and, will be not can be owing to

flap

164 and 166 being installed on the underwear 136 and biased downward.Another advantage of this design is, can be made into absorber 90 as needs widely, and can reduce the size of flap 164 and 166.Because

flap

164 and 166 is by

passage

120 and 122 rather than stretched downwards and inwards by the outer ledge of absorber 90, there are the flaps 164 that stretch downwards by

passage

120 and 122 and 166 the 3rd benefit to be that their help the lateral edges 138 and 140 of underwear 136 is remained on its position.When as shown in Figure 29

such retainer flap

164 and 166, underwear 136 can not easily outwards move, and leaves

passage

120 and 122.

Referring now to Figure 30,, the absorbent article 180 that illustrates in two noticeable modes with different at the embodiment shown in Figure 29.The first, this is designed to overlap each other to

flap

104 and 106, and links together by erecting device 116 and 118.The second, the first and

second side

78 and 80 that stretches in the vertical that raises lays respectively at the inside of vertical outer surface 94 and 96.First and second sides 78 that stretch in the vertical that raise and 80 more close being provided with have narrower groin women at interval with making absorbent article 180 to be fit to better respectively.Again,

flap
