Foot mouth hoop can or use on the inboard that any fastening technology that other is suitable for or material be attached to body portion with any technology described in this description.Foot mouth hoop can be attached on the body-side layers of body portion, backing element or other certain layer, and this depends on the width and the position of these layers in the body portion.Foot mouth hoop can be positioned at the Moisture-absorptive lining pad top all over, also can be positioned partially at above the Moisture-absorptive lining pad or fully not above Moisture-absorptive lining pad.For the width of top act is the adult of 27 inches (686 millimeters) (being 36 inches, 914 millimeters) under the extended state with the example of panties (but not any restriction of tool), and foot mouth hoop is positioned at next-door neighbour's Moisture-absorptive lining pad place, shown in Figure 1A.The example of the foot mouth hoop that can adopt is disclosed in the U.S. Patent No. 5 of Enloe, 415,644, the U.S. Patent No. 5,413,570 of Enloe, people's such as Enloe U.S. Patent No. 4,846,825, the U.S. Patent No. 4,846,823 of Enloe, the U.S. Patent No. 4 of Enloe, 704,116, the U.S. Patent No. 5,599,338 of Enloe, the U.S. Patent No. 5 of Schleinz, 649,918, the WO 97/21410 of Faulks, in people's such as LeMaheiu U.S. Patent No. 5,620,431, all these patents have all transferred Kimberly-Clark company, quote these patent disclosure data here as a reference.

Elasticized flaps can be made with any rubber-like material.It can be monolayer or multiwalled.For example, elasticized flaps can be made with a kind of multilayer material, and this material is clipped between the two-layer fabrics by rubber-like monofilament, fiber, thin slice, tape or twisted wire and forms.The examples of material that may be used for making elasticized flaps is disclosed in the U.S. Patent No. 3,371,668 of the U.S. Patent No. 4,606,964 of Wideman and Johnson, and the open source information of quoting these patents here as a reference.Elasticized flaps can be made with a kind of stretch-bonded cascade type material, and this material is by two layers of material and is that the high-elasticity fiber net of monofilament constitutes through melting and spraying or pushing between this two layers of material.Elasticized flaps can also be made with the material or the thin neck adhesive layer laminate materials (NBL) of a kind of thin neck bonding (neck bonded) type.Only tool is restricted as an example and not for described two layers of material, can be such as spunbonded materials such as spunbond polypropylene, artificial silk or woven fabric-type materials, thin film or porous membrane.Elasticized flaps can be a breathable or gas impermeable, certainly as the material of elasticized flaps breathable preferably.Described elastomeric fibre net can be made with Kraton .

Another example that can be used for making the material of elasticized flaps is called as the composite of " stretch-bonded lamination " or SBL.This material generally has two-layer at least, but one deck wherein is the bunching layer, and another layer is an elastic layer.Be at elastic layer under the state of elongation and be combined with each other two-layer, but therefore after elastic layer is lax this bunching layer just bunching get up.This MULTILAYER COMPOSITE elastomeric material can be stretched over such degree: the inelastic layer of bunching between bonding location stretches elastomeric material.A kind of MULTILAYER COMPOSITE elastomeric material is disclosed in the U.S. Patent No. 4,720,415 of authorizing people such as Vander Wielen as an example, and the open source information of quoting this patent here as a reference; Each layer of same polymer is to use many row's extruders to produce in this MULTILAYER COMPOSITE elastomeric material.Other composite elastic material is disclosed in the United States Patent (USP) 4,789,699 of authorizing people such as Kieffer, the United States Patent (USP) 4 of authorizing Taylor, 781,966, authorize the United States Patent (USP) 4,657 of Morman, 802 and 4,652,487 and the United States Patent (USP) 4,655 of authorizing people such as Morman, 760 and 4, in 692,371, the open source information of quoting these patents here as a reference.

1993.7.13 authorize the United States Patent (USP) 5 of Morman, 226,992,1994.8.9 authorizes the United States Patent (USP) 5 of Morman, 336,545 and 1996.5.7 authorize people's such as Haffner United States Patent (USP) 5,514,470 have narrated the example of the NBL material type that may be used for the elasticity wing panel, and the open source information of quoting these patents here as a reference.

A kind of ventilative material that is made of two spunbond polypropylene layers is an ideal material of making elasticized flaps.Be stained with elastica as shown in Figure 2 between the two-layer spunbond polypropylene of this material.In Fig. 2, be stained with elastica 26 between the two-layer spunbond polypropylene of elasticized flaps 7.Elastica extends along the direction of the width dimensions 19 of panties and wing panel.Elastica is not that segmentation is arranged abreast, but forms zigzag fashion near the wing panel edge more.As shown in Figure 2, elastica should be the single zigzag line that is arranged in ideal conditions.Yet alternative is that the many elasticas that can adopt comprise the elastica scheme that is arranged in parallel.Elastica 26 is to be fixed on locational between the spunbond layer with binding agent and/or ultrasonic method.This binding agent can adopt the binding agent of any kind disclosed herein, or adopts the known any binding agent of this specialty, as long as have elasticity after this binding agent solidifies.Have restrictedly as an example and not, this class binding agent can be from National Starch ﹠amp; Chemical Company, Bridgewater, New Jersey and Ato-Findley Adhesives, Wauwatosa, Wisconsin obtains.Can apply binding agent with any method that the known this paper of comprising of this specialty had narrated.

In order to form elasticized flaps, the optimal path that applies binding agent is to adopt a kind of narrow slit paint-on technique that generates new and different elastomeric materials.This technology forms many along extension of length (that is perpendicular to width dimensions 19) direction and spaced apart parallel adhesive tape 27 on wing panel and panties.In addition, this horizontal bunching effect also can adopt ultrasonic bonding, heat bonding or pressure adhering method to form.

The width range of this adhesive tape can be from about 1/32 inch (0.8 millimeter) or be smaller to about 3  inches (91 millimeters) or bigger that ideal width range is to about 2 inches (51 millimeters) from about 1/8 inch (3.2 millimeters).Spacing between the adhesive tape can be identical or different with the width of adhesive tape.In addition, adhesive tape also can degree of broadening.The desired configuration of adhesive tape is: the adhesive tape width is 1/8 inch (3.2 millimeters), and the spacing between each adhesive tape also is 1/8 inch (3.2 millimeters).Interval between the adhesive tape forms the material with horizontal bunching effect or rivel.Have been found that this horizontal bunching effect has improved the comfortableness and the suitability of panties and wing panel widely, and increased the elastic range of wing panel.Therefore, the wing panel with the effect of this transverse elasticity bunching is configured under identical tension force and the identical elastica size situation, presents bigger percentage elongation than the wing panel that does not have the effect of transverse elasticity bunching.The formation of adhesive tape can cause producing the attachment region of a low elasticity, that is produces little elasticity or inelastic zone in wing panel.This depends on the type of employed binding agent and quantity and irrelevant with the elasticity of elastica.Alternative is to replace adhesive tape with ultrasonic adhesive strip.The material that this class has horizontal bunching effect is another independently theme of patent application, and this patent application is declared on the same day with people's such as Fell name and present patent application, and lawyer's identification number of this patent application is 659/489.Here quote this patent application as a reference.

The maximum extension amount that is shaped on the elasticity wing panel of this adhesive tape is higher than the wing panel made from routine techniques widely.For example, a wing panel that adopts 1/8 inch (3.2 millimeters), adhesive tape of spacing 1/8 inch (3.2 millimeters) to make has the elastica of being placed with 250% percentage elongation, and the maximum elongation rate of this wing panel will be 240%.And the expected value of the maximum elongation rate of the conventional composite under the similarity condition is about 212%.Therefore, this elasticity wing panel allows to the much bigger elongation of elastica input; And under identical initial elasticity percentage elongation situation, make this wing panel have much bigger Breadth Maximum.

Before fastening wing panel can use any material manufacture, have can be mutually bonding with closed device surface the surface, this class closure device is that this specialty is known.For instance but tool is not restricted, such device for example can comprise: machanical fastener, binding agent band, binding agent tongue piece, button, band, Velcro ^, hook, clip, snap-fastener, hook and circle, button and ring, interlocking hook (interlocking hook), hook and hook device.The common unsettled U.S. Patent application No.754 that Stokes files an application at 1996.12.16, narrated in 419 a kind of be suitable for making before the material of fastening wing panel, this material can easily be fastened on the closed device of hook again.This patent application has returned Kimberly-Clark company to own, quotes its open source information here as a reference.

The total structure of these panties has many schemes and possible embodiment, and these embodiment are proposing many schemes and replacement scheme aspect dress, use and the suitability of panties.

Stiffeningization processing can be done in the whole outer rim of one or two elasticity wing panel that is the edge that is pasted with closed device.Should stiffeningization processing can implement for example ultrasonic, hot, deposited glue or use additional material with any known method.The elasticity at stiffening position can reduce or become inelastic.The panties that have a stiffening wing panel outer rim can make fastening wing panel be more suitable for body shape and be tiled on the human body, and can prevent to produce the gap between the closed device of wing panel.

The shape of flank is varied, and wherein a kind of like that, formed a bailing bucket (bucket) at the seam crossing of wing panel and body portion shown in Fig. 4 A and 4B, and this bailing bucket has strengthened the suitability of panties.Another advantage of this shape for can economical with materials expend because several wing panel can be nested in together in manufacture process, the material of several wing panels can suffer very closely before shearing, this just makes the quantity of waste material reduce.

The extending range of elasticity wing panel depends on the kind of the kind of the size of panties, used tablet, used elastic component and the shape of wing panel.For its shape wing panel of the Mature Audiences shown in Fig. 4 A and 4B roughly, its extending range is generally from about 75% to about 200%, is preferably from about 100% to about 175%, and ideal is from about 120% to about 150%.

The tension force of elasticity wing panel depends on the kind of the kind of the size of panties, used tablet, used elastic component and the shape of wing panel.For its shape wing panel of the Mature Audiences shown in Fig. 4 A and 4B roughly, its tension force is generally from about 400g to about 1000g, is preferably from about 500g to about 900g, and ideal is to about 800g from about 600g.Yet should be appreciated that tension force that is adopted and extending range can be more greater or lesser for the different embodiment of panties and the panties of different purposes.

When the peak tensions of the elastomeric material of many adult's disposable products stops length (stretch to stop length) through measuring its meansigma methods for stretching tensile about 83%.Because peak tensions point is very near from stretching halt, most products all are to use under less than 100% stretching, extension halt situation.For most of user, the tension force that stretches the halt place does not have real value, because they can find elastic component is moved to when stretching halt and will think that product is too tight.

Also measured the average peak tension force of the 8th circulation time that elastomeric material loads repeatedly-relax.Consider elastomeric material inherent stress along with lax characteristic of time, for measuring the impression of user in a period of time, measure the accuracy that will improve measurement the 8th circulation time.

Tonometric program is as follows:

1. the ergometer of 10 ft lbfs is installed on the Sintech instrument;

2. cut 20 3 inches * 3 inches sample;

3. a sample is clipped to Sytech, a division of MTS System Corp.Ressarch Triangle is on the jaw of the Sintech tension tester that NC produces;

4. the distance between the jaw is set at 2 inches;

5. making stretches under the pulling force of tester with 2000 grams stops length to obtain to stretch, and the last spacing that this length equals jaw deducts the initial separation of jaw, that is the distance between the jaw.Sample number is 10;

6. the meansigma methods that stretching, extension is stopped length multiply by 0.83 extended length value can calculate cyclic test the time;

7. make tester that sample is stretched to the extended length of calculating and return 0 extended length, so repeat 8 times.Sample number is 10;

8. the 8th circulation time sample is moved to outside the extended length of 2000 gram force correspondences, and generated a relaxation curve figure, the return curve after the circulation that just stretches for the 8th time;

9. make two tangent lines on curve, the starting point with curve is tangent, and another is tangent with terminal point.These parts of curve roughly are linear;

10. be approximately equal to stretch corresponding to the extended length at two point of intersection of tangents places and stop 83% of length.Read tension force corresponding to this intersection point.And this tension force of 10 samples averaged.This peak tensions meansigma methods promptly is not to use the tension force of this elastomeric material that the person will experience when wearing product.

Also can endure with all one's will processing to the joint between wing panel and the body portion.Stiffeningization of this joint reduced panties curling tendency taken place, thereby improved the suitability of medicated clothing.Joint can be with known any the enduring with all one's will of technology of this specialty, comprises that being used for of narrating above endure with all one's will the method for handling to the outer rim of wing panel.

Panties can wear " J " font, " U " font or other to be user or the desirable form of nursing staff.Panties fastening good after, the upper limb of flank and body portion flushes, the panties in the use have one continuously around the belt of human body.When wearing this product, these different shapes are conspicuous for wearer or nursing staff.

The shape of flank and the quantity of closed device and position can be diversified.Fig. 6 A has showed several examples in this class configuration to 6C.Preferably, each elasticity wing panel has two closed devices at least, and one near waist (that is rear end), a close bottom (that is leg opening).In order to adapt to different users's the bodily form, can be identical or different with the formed tension force of two lower limbs around waist.For instance, that closed device of the most close leg opening that is down closed device can have different configurations, for example, therefore should can attach in shank and the stomach intersecting area zone in addition by the closure device than longer, bigger near the device of waist or have different shapes.Alternative is to repair to obtain different cooperations and tension force fastening wing panel.For instance, if closed device is fixed in such zone, leg curvature can make device unclamp in this zone, some material that falls into this zone can be removed to eliminate this phenomenon so.

Can adjust the position of the attachment point on the fastening wing panel of closed device pro-, respectively the tension force around shank, buttocks and waist is regulated independently, to satisfy the needs of user better.Like this, just can make around the tension force of waist, or make tension force around shank, or reach other various combination of these variables greater than tension force around waist and buttocks greater than tension force around shank and buttocks.Can substitute successive flaky material with the strip material that suitably-arranged forms in addition and make fastening wing panel.
