When the article is in the unfolded state, the elastic Fully straight so that the diaper edges can be sealed against the legs during use , Extending essentially along the side of the absorber.   US 4,050,462 relates to a diaper having an elastic body, said elastic body being in a flat state The diaper crotch area to extend straight at Means to increase the unit volume and surface area of the absorber by shrinking and pleating Illustrated.   A diaper having an essentially straight elastic body forming a V-shaped configuration is disclosed in WO 88/00010. It is shown. The elastic body extends inside across the absorber of the diaper, causing the elastic body to contract. Define the boundaries of the area that will be deformed by use. Extending the elastic body mainly at the straight section The elastic body tries to reduce the overall length of the article, so that the pleating of the article as a whole Is done. The area enclosed between the many linear elastic parts is reduced by the contraction of the elastic parts. The ur shape is given.   A method for producing diapers is disclosed in US 4,801,345. This method is for diaper crotch Including the application of elastic along the minute. In this method, the elastic is along the long edge of the diaper. Therefore, it extends concavely to the outside and extends entirely toward the absorber. The purpose of the elastic body is It is fundamentally to achieve a tight connection of the diaper's edge to the wearer's leg. A further effect is the constant shrinkage and pleating of the absorber across the crotch.   In a flat diaper, extend completely straight and extend completely to the side of the absorber A diaper having an elastic body is disclosed in EP 0,219,326. Elastic body is both crotch Located along the outer edge of the diaper on the side and also trimmed on both sides of the absorber I have. In addition to maintaining an upright seal edge by trimming, the elastic Ensure constant crimping and shrinkage of the container.   GB 2,234,157 around the waistband of the training pants, on the legs of the wearer Trainee having an elastic body extending along the edge of the crotch and across the crotch About trousers. Elastics surrounding the legs reduce the risk of leakage, but The cutting elastics are only arranged to allow a reasonable application of continuous elastic yarn. No. The structure and method are particularly adapted for training pants type diapers. SUMMARY OF THE INVENTION:   It is an object of the present invention to disposable liquid absorption to apply a very effective collecting shape during use Is to provide a sexual article.   Diapers with leg elastics according to US 3,860,003 became common in the 1960s Since then, a huge number of patents on diaper elastics have been filed around the world. ing.   The elastic body may be longitudinally and / or longitudinally to form a three-dimensional shape or a leakage barrier. Or it has been adapted laterally.   The elastic body is also applied in a curved shape along the cover edge outside the side edge of the absorber However, the curved shape has been selected for better application to the user's body type. It just does.   According to the invention, a completely new elasticity which gives the product many advantages in a particularly simple way Body effects made.   The above objects and novel advantages are attained according to the present invention, that is, the features apparent from the appended claim 1. Achieved by the goods. BRIEF DESCRIPTION OF THE DRAWINGS:   The present invention will now be described by way of example with reference to the accompanying drawings.   FIG. 1 is a plan view of an article of the present invention according to a first embodiment of a diaper,   FIG. 2 is a perspective view of the diaper of FIG. 1 essentially in use;   FIG. 3 is a perspective view of the article of the invention according to the second embodiment in use,   FIG. 4 is a longitudinal section along the line IV-IV of FIG. Yes,   5 is a corresponding longitudinal section along the line VV of FIG. 2 of the diaper in use,   FIG. 6 is a transverse section along line VI-VI of FIG. 2 of the diaper in use,   7-9 illustrate further specific examples of the diaper,   Figures 10-12 illustrate three additional useful embodiments. Detailed description of preferred embodiments:   Particularly representative articles of the present invention are selected as specific examples. It is liquid or feces So-called incontinence diapers, i.e. adults, not children It is a diaper.   As is clear from the first specific example (refer mainly to FIGS. 1, 2 and 4), the diaper 10 Is constituted by a cover 11 surrounding a core in the form of an absorber 12. Shown in FIG. In a flattened, unfolded state, the core has two major surfaces facing away from each other ( That is, the interior side 13 intended to face inward towards the user and the exterior side Represents a relatively flat main profile with an outer side 14) intended to be used. Further absorption Body 12 provides a suitable outline anatomically adapted to the user's body to absorber 12 The given rounded surrounding edge portion 15 is represented. Absorber 12 is stiffer than the rest of the absorber A central portion 16 is provided. This is because the basic weight of the central part 16 is larger than that of the rest of the absorber. Achieved by large absorbers. Even if the central part is thicker than the rest of the absorption layer Good, but having the same thickness in the embodiment shown, but with It has been compressed.   In the embodiment shown, the cover 11 comprises two layers having different properties from each other. 17 and 18, the two layers correspond to the inner side 13 and the outer side 14 of the absorber, respectively. And two layers connected to one another outside the edge 15 of the absorber. An edge 19 is formed which surrounds the housing and surrounds the diaper as a whole in a flanged manner. At the edge portion 19, the two layers 17, 18 are positioned close to each other and They are connected to each other by a mixture.   The specific components used to form the diapers shown are for such purposes Any of the components commonly used for can be used. Inside The layer 17 applied to the part side 13 is made of a soft non-woven or polyethylene A soft and flexible liquid-permeable material such as a plastic film It may be. Layer 18 on outer side 14 is polyethylene, polypropylene Opaque materials such as thin (for example, 20μ) plastic film such as polyvinyl chloride It is made of a liquid material. Absorber 12 is made of cellulose fiber or various types of super absorbent material Etc.   1, the diaper shown in the example has a rear part 21 and a front part. Asymmetric sand with waist or crotch portion 20 extending in the direction toward It has a major or peanut shell-shaped main profile, with the rear and front parts worn during use It is intended to contact the corresponding part of the person. Absorber 12 is the same as crotch 20 Than the outline of the diaper 10 which gives a wider width than the diaper edge 19 of the height It is getting thinner to a large extent. Give the diaper 10 a suitable shape during use For this purpose, the diaper 10 is provided with a contractible elastic body 23 arranged in a configuration and position unique to the present invention. available. The preferred form is to allow the diaper to be partially absorbed and partially manufactured during use. Liquid and solid excreta (urine, blood) from the body due to product retention in the form of Or other body fluids or feces). For this purpose The elastic body 23 has arcuate curved portions 24 and 25 extending across the absorber 12. Accordingly, it is at least partially arranged. In the example shown, two arcs in a row Elastic parts 24 and 25 are arranged, and they are edge elastic bodies (see below). At two intersections 26, 27 near the long edges 28, 29 of the diaper, respectively. Basically touches at their ends.   The elastic body 23 is bonded to at least one of the layers 17 and 18 of the cover 11, and the first member In the embodiment, it is bonded to the liquid-permeable layer 17. In the example shown, the elastic is a layer 17, i.e. between the absorber 12 and the layer, but of course instead of the outer layer It may be applied to the unit side. The elastic body is, for example, a very elastic material (for example, rubber) With an elongated elastic member having an elastic core in the form of a thread or band and a bonding agent It consists of an elongated elastic member with a wound thread cover that can be wound. The elastic core thus allows elastic movement and at the same time the elastic core of the diaper layer 17 Enables the fixation of The elastic body will try to shrink and the elastic thread or band will serve this purpose. Pre-stressed (ie, to some extent before settling occurs in diaper layer 17). Will be broken). Anchoring may be at a certain part of the extension of the elastic body or at all This is performed by the bonding agent 30 applied at the time. In the example shown, the bow Each of the raised portions 24, 25 is a double elastic, i.e., two adjacently extending bullets. It is arranged with the sex members 30, 31, 32, 33. One of those curves One elastic member 33 of the part 25 becomes edge elastic bodies 34 and 35, and Long edge of the diaper up to the intersecting positions 26 and 27 of the part 24 It extends along both 28 and 29. In the example shown, the edge elastics 34, 3 5 is an arc which extends essentially straight but has a small curvature, ie a large radius of curvature May be provided.   The diaper is essentially a plan view in FIG. The contraction effect of the elastic body is shown in a visible state. .   FIG. 2 shows the diaper in a condition for use. This shape handles diapers Formed as soon as it starts, this effect is described in detail below. Diapers are flat As far as possible, essentially no shaping takes place except that the absorber is slightly compressed . Before the diaper is applied to the use position, the area 38 located inside the elastic body is If pressed down when bending one, the desired shape may be forcibly given by hand. No. The bow-elastic body attempts to shrink and cooperates with the bonding of the layer to the absorbent core. By fixing one layer 17 of the cover to the absorbent core, In conjunction with the deformable properties of the cover, the elastic body is essentially sagging with respect to the flat inside of the article. A straight bowl wall 39 'is formed. Outside the outer edge of the absorber in the crotch area of the article The bar part has a bowl wall 39 "surrounding the bowl-shaped space together with the bowl wall 39". Form.   FIG. 3 shows a diagram corresponding to FIG. 2 of another specific example of the diaper. 23 'in the figure The elastic body referred to by reference has the same configuration as the first specific example, but the outer layer 18 ( That is, it is bonded to the liquid impermeable layer). Again, the elastic thread or band is It may preferably be applied by an inner bonding agent. And on the contrary, this is inside Therefore, it must be bonded to the absorber. The corresponding preferred bowl is this example Is also essentially achieved. The force acting on the diaper by the bow of the elastic body, These elastic parts provide the necessary diaper deformation for the formation of vertical bowl walls. It is particularly important here to be assisted by outward forces before giving. You.   The elastic part contracts at the wide part of the edge part 19 just before the crotch part 20. Lifted in both embodiments to try, ie to reduce the length . When the diaper is used, the raised longitudinal edges 36, 37 are at an altitude relative to the body. Try to squeeze the wearer's body inside the thigh to form a liquid-impermeable bond. In particular, in the first embodiment of FIG. 2, a distinct, essentially vertical bowl wall is Appears inside the elastic part that has been pressed. Furthermore, a certain amount of pleating prevents shrinkage of the layer due to the elastic body. Therefore, it appears in the horizontal direction. As mentioned earlier, the bow bowl wall is essentially flat on the bowl May be essentially perpendicular to the line along the bottom. Bow bowl wall is elastic By choosing to prestress and by the deformation properties of the absorber Form an acute or obtuse angle with the line along the bottom of the urn. At acute angle, pocket shape Is obtained near the elastic body. Therefore, the surrounding elastic body 23 is a body product. To form the upper edge of the bowl 39 which acts as a collecting space. This has a relatively large capacity It is especially useful in cases of severe incontinence that can grow. Feces are collected in the diaper collection area It can be received in this space without danger of going outside. Absorber 12, special The portion located inside the elastic body 23 has a function of absorbing the liquid, The purpose of the wall is before the absorber 12 can completely absorb all the liquid volume, The purpose is to prevent leakage of liquid to the outside of the diaper. The raised edge 19 Due to the position of the diaper, for example when the wearer is lying Keeps liquids that are not immediately absorbed. As soon as the wearer changes body position The liquid can be absorbed by the absorber.   The longitudinal section in FIGS. 4 and 5 and the transverse section in FIG. 6 illustrate the effect of forming the shape of the elastic body. You. This will be described in more detail. The elastic body shrinks and therefore tries to reduce its length With this, the shape forming action of the elastic body occurs. By fixing the elastic body to the cover, The bar is subjected to a contraction movement of the elastic body. Cover layer absorbs across those surfaces It is in turn connected to the body, whereby the plane tension of the cover layer is transmitted to the absorber. Sucking The elastic body across the main part of the spread across the collector is applied in a curved form The contraction action is caused by force components 40 and 41 at each point crossing the curved portion of the elastic body. (See FIGS. 1 and 4), wherein the force component is a pair for each point of the curved part. Directly directed to the corresponding center of curvature. If the curved part has a different radius of curvature If so, there are different centers of curvature for each different point. However, The diaper absorber 12 exhibits a certain compression resistance, which is reduced by the contraction force 40, 41 of the elastic body. This is illustrated in FIG. 4 by opposing reaction force components 42,43. Resistance to compression Is transverse to the symmetry plane 44 of the disk-shaped absorber (ie, the force direction in the plane of the paper). (Transverse to 42, 43). Especially this is more This is the case for a change to a rigid central part 16. As mentioned above, the absorber is the rest of the absorber The inside of the curved elastic part is stiff and therefore more elastic at the stiffer central part 16 More deformable around and outside the body. The absorber 12 is preferably a so-called It is made of lulose fluff pulp, and is relatively easy to bend with the cover 11, The stiff central portion 16 exhibits a certain resistance to compression. These characteristics are bow In order to cause deformation of the article in the area with the stiffener, a pair of forces 41, 43 and And torsional moments caused by each of It is represented by arcuate lines 48, 49, 50, 51 which schematically represent the partial bending directions. Due to the position of the elastic body outside the plane of symmetry 44, the bending moment of the absorber 12 is already It occurs in a flat state. However, the article does not deform when it is flat This deformation does not begin until the article is handled.   FIG. 5 illustrates a bowl formed by an elastic body, the elastic body being related to the plane of the article. Extending essentially outside the absorber wall and essentially vertical bowl wall 39 'along the bow It is limited by a bowl wall 39 "formed by a portion of the cover.   These parts are formed by the action of the edge elastic bodies 34 and 35 combined with the bow elastic body. Lifted.   The cross section in FIG. 6 shows that the bowl is relatively deep and therefore can hold a large amount of waste. Show.   In the embodiment shown in FIGS. 1-6, the elastic body as a whole is already made Each form a closed loop.   FIG. 7 shows a curved elastic portion 60 forming a delimiting lateral wall 61. A specific example of a diaper in which an elastic body extends laterally across the crotch portion 20 is illustrated. This In the case of, the demarcation is obtained between the front part 22 and the rear part 21 of the diaper, More feces and urine are separated, giving a large volume for fecal collection space.   FIG. 8 shows a further different example, in which each of the rear part 21 and the front part 22 has a cover. Bowl shape with lateral bowl rims 68-71 inside each of the heated sections -Shaped spaces 66, 67, each of which has two curved elastic portions 62, 63, 6 4,65.   FIG. 9 shows another form, in which the main contour of the flat article is essentially rectangular. Can be. The hourglass shape with the tapered crotch portion 20 is formed by the contraction action of the elastic body. can get. Again, lateral bowl rims 72, 73 are formed to prevent edge leakage. And give an effective barrier.   The example article of FIG. 10 includes a front portion 74, a rear portion 75, and a crotch portion 76 therebetween. With an asymmetric hourglass shape. The absorbent is preferably a chemical cellulose fluff pad. Hourglass-shaped lower layer 77 applied closest to the impermeable outer layer of Absorbent layer 77 made of porous and elastic material and receiving liquid quickly Closest to a liquid permeable inner layer 78 extending across the crotch region of the article having the ability to pass through Consisting essentially of an elliptical upper absorbent layer 79 applied. For upper absorbent layer Examples of suitable materials are mechanical cellulose fluff pulp or fiber filled cotton.   The essentially elliptical upper absorbent layer 79 has side portions 82, 83 which are sandy It extends laterally outside the meter-shaped lower layer and forms flexible side portions 82 and 83. In the crotch region, the articles are arranged in three elongated closed loops 84, 85, 86 Compressed by the pattern formed by the compressed traces. Compression pattern is inner layer, upper It is applied to the deep part of the lower absorption layer via the partial absorption layer. Compression pattern part 87 In, the article is substantially consolidated by the compression traces, this part being more rigid than the rest of the article. It becomes. The elastic threads 88, 89, 90 are prestressed and moved forward to the opposite side of the article. Two threads 88, 89 extending in an arc from one side of the article traversing the inward section and the rear Around a stiffer section having elastic threads 90 extending in a corresponding manner across the lower section Applied to Curved elastic portions 88 ', 89', 90 'are curved elastic portions As described with respect to the above-described embodiment to form a bowl wall along the minute Affects goods as well. The bent side portions 82 and 83 are used when the product is used. To prevent leakage in the lateral direction of the product. To form   FIG. 11 shows that the hourglass-shaped lower absorbent layer 91 has different thicknesses at different portions. The illustrated example is shown. In the crotch area of the article, the lower absorbent layer is different from the hourglass shape And has two side portions 92 and 93, which protrude sideways and are provided at the crotch portion of the product. It is thinner and easier to bend than the rest of the hourglass-shaped absorbent layer. When the product is used, The bendable side portions 92, 93 surround the stiffer portion 97 with respect to the rest of the product. It is lifted by sex threads 94, 95 and 96. A specific example of FIG. Includes an essentially rectangular top layer 98 of rupe or fiber wadding. As with the previous example The bowl wall is formed along a curved elastic part.   FIG. 12 shows a further specific example. The article has a cover consisting of an inner layer and an outer layer You. Absorber 99 consists of one layer of cellulose fluff pulp. Product is in this part Pattern formed by a number of compression traces 100 to increase the rigidity of the absorbent layer in Is given.

The recesses 104 and 105 are arranged laterally outside the recesses. A folding guide is formed for the outer parts 106, 107 of the absorber. Goods When used, it is folded along the indentation, and thus the outer part of the absorber The minutes 106, 107 form a side leak guard.   The present invention is not limited to the embodiments described and illustrated, but may vary within the scope of the appended claims. Can be changed. Children's diapers, trays other than incontinence diapers Trousers, sanitary napkins and the like may be associated with the present invention. “Essentially The term “continuous curved section” mainly relates to an arc or an arcuate curved section But as an alternative for a combination of multiple straight sections, preferably a semi-arcuate It may also include at least three straight sections.

[Procedure for Amendment] Article 184-8, Paragraph 1 of the Patent Act [Date of Submission] December 6, 1997 (1997.12.2.6) [Content of Amendment] (Corrected on the 3rd page of the original text of the specification) GB 2,234,157 is training A training pant having an elastic body extending around the waistband of the pant, along the edge of the crotch to the wearer's leg, and across the crotch. While the elastic surrounding the legs reduces the risk of leakage, the elastic across the crotch is only positioned to allow for reasonable application of continuous elastic yarn. The structure and method are particularly adapted for training pants type diapers. GB-A-2 156 681 is located inwardly in an arcuate edge and in a central longitudinal direction along each of said edges, and preferably outwardly from the seal with a fluid permeable cover attached directly to the fluid impermeable barrier. A sanitary napkin provided with the provided elastic body is disclosed. This causes the elastic to clamp the end of the napkin to provide a cup-shaped profile with a profile bottom generally corresponding to the wearer's perineal area. Summary of the Invention: It is an object of the present invention to provide a disposable liquid absorbent article that applies a very effective collection shape during use. Since the diapers with leg elastics according to US 3,860,003 became common in the 1960s, a vast number of patents on diaper elastics have been filed worldwide. Elastics have been adapted longitudinally and / or laterally in the diaper to form a three-dimensional shape or leak barrier. Elastics have also been applied in a curvilinear shape along the outer cover edge portion of the absorber's side edges, but the curvilinear shape is only selected for better application to the user's physique. The invention has created an entirely new elastic effect which gives the product a number of advantages in a particularly simple manner.
