Disposable nappy

The present invention relates to a disposable diaper, and more particularly to a diaper according to the preamble of appended claim 1.

Disposable diapers are well known products designed for use by young children and incapacitated 10 people. Disposable nappies are kept around the wearer's lower body and are intended to absorb and contain excreted urine and faeces in order to prevent staining, wetting, etc. of objects (eg clothing, bedding, other persons, etc.) that may come into contact with such diapers during use. with.

Disposable diapers are available in a number of different embodiments, generally consisting of an absorbent core sandwiched between a liquid-permeable top surface facing the user and a liquid-impermeable bottom surface. In addition, a variety of disposable diapers are available in which resilient members are provided at the contact points of the user's thighs to provide flexible leg openings in the diaper. For example, in U.S. Patent 3,860,003, issued to K.B. Buell, January 14, 1975, discloses a unitary disposable diaper having opposed, resilient side strips in the crotch portion, each of which is secured with a resilient member forming a flexible, collapsible line along the side strip length 30, making the side strips flexible and effectively sealing around the user's legs. The resilient members shown by Buel are operatively associated with the side strips such that the resilient member normally assembles the side strip material around the side strip material in an unstretched state and forms a resiliently retractable line 2,89866 along the length of the side strips adjacent their outer side edges. A disposable diaper with a resiliently compressible leg portion is disclosed in U.S. Patent 4,050,462, issued September 27, 1977 to Woon et al. This sheath 5 comprises a leg portion located between two opposite lumbar portions, which is compressed longitudinally by resilient members attached to the lower surface adjacent to each side edge of the leg portion. The resilient members are designed so that in the unstretched state, numerous coarse transverse wrinkles are formed across the width of the slot portion of the sheath. These transverse ribs then reduce the length of the branch portion without reducing the amount of absorbent material contained therein, thereby increasing the absorbency of the branch portion of the sheath per unit area.

Other known disposable diapers have sought to shape the suction pad contained in the diaper to reduce the size of the crotch portion and to improve the fit of the diaper around the wearer's thighs. For example, U.S. Patent 4,336,803 to V.L. For a backpack on June 29, 1982, 20 disposable diapers are shown with a shaped absorbent pad that can reduce the size of the diaper between the wearer's legs but still maintain excellent absorbency. In particular, the Repke shaped cushion has a plurality of indentations formed opposite the side edges so that a short area is formed between one end of the cushion and the deepest point of the indentations and a long area is formed between the opposite end of the cushion and the other indentation. The short part of the suction pad is to be placed in front of the child and the longer part then extends between the legs and buttocks of 30 children. Such a design is said to reduce the size of the diaper without compromising the absorbency of the interior. The diaper according to Repke's patent publication 4 336 803 further has elastic members arranged on the longitudinal edges of the absorbent inner part, thanks to which the diaper 35 fits snugly around the child's legs. Similarly, U.S. Pat. No. 3,699,846, issued to U.S. Patent No. 4,430,086 to V.L. For a reptile on February 7, 1984, a disposable diaper is shown, which may include a shaped absorbent core and has creasing members comprising at least two separate resilient elements. In particular, the sheath according to Repke's patent publication 4 430 086 has two elastic bands extending along opposite longitudinal edges of the sheath and forming two separate and distinct creases which provide two separate sealing lines around the user's legs. When the elastic elements are arranged apart from each other, the area of distribution of the elastic forces is claimed to be larger and the compressive effect on the user's thighs is reduced.

Despite all the development work in the field, 15 there is still room for improvement in the fit of disposable diapers while reducing the amount of urine leaking along the legs. In addition, the previously known diapers tend to lower down and press inwards from the crotch during use, whereby the comfort and fit of the diaper as well as the absorbency 20 are further impaired. The flexible leg openings tend to migrate to the user's femoral folds in the crotch region, increasing the problem of descent and indentation and impairing the ability of such known diapers to contain secretions.

The object of the invention is to eliminate the above-mentioned problems.

It is a further object of the invention to provide a disposable diaper having leg tensioners that stretch the leg portion of the diaper in use laterally outwardly 30, thereby improving the fit, tightness and secretion binding capacity of the diaper.

It is a further object of the invention to provide a disposable diaper which, due to its structure, tends to direct secretions directly into the absorbent interior of the diaper, thereby avoiding leaks.

, 89866 4

In order to achieve said objects, the sheath according to the invention is characterized by what is stated in the characterizing part of the appended claim 1. A preferred embodiment of the invention is set out in claim 2.

The main advantages of the diaper according to the invention are that it has a good fit, comfort and absorbency.

Although a claim defines the scope of the invention at the end of the description, the invention may be more readily understood from the following description with reference to the accompanying drawings.

Figure 1 is a partially sectioned top view of a disposable diaper according to the invention in an unbent condition.

Figure 2 is a partial, schematic cross-sectional view-15 of a prior art disposable diaper having elastic thigh straps, shown as it would appear between a user's thighs.

Figure 3 is a partial, schematic cross-sectional view of a prior art disposable diaper having double elastic thigh straps, shown as it would appear between a user's thighs.

Next, the disposable diaper 10 according to the invention, shown in Fig. 1, will be considered in detail. The term disposable diaper generally means. 25 garments worn by young children or incapacitated persons, placed between the thighs and fastened around the wearer's pelvis, intended to be disposed of after a single use (ie not to be washed or otherwise treated for 30 re-uses).

The disposable diaper 10 is shown in Figure 1 in a partially sectioned perspective view with the diaper in an unbent condition. As can be seen in Figure 1, the disposable diaper 10 comprises a substantially liquid-permeable top surface 50, an absorbent core 40, a liquid-impermeable bottom surface 30 and branch tensioners 60. Although 5 89866 top surface 50, an absorbent core 40, a liquid-impermeable bottom surface 30 and branch tensioners 60 can be well In some ways, a preferred embodiment of a disposable diaper is disclosed in U.S. Patent No. 5,388,003, entitled "Contractible Side Portions for a Disposable Diaper", issued to KB Buell ille of 14 January 1975 and to which reference is made in that regard.

Thus, it is preferable to place the absorbent inner portion 40 between the upper surface 50 and the lower surface 30 so that the lower surface 30 is attached to the upper surface 50. In the context of the invention, the upper surface of the disposable diaper is the layer closest to the user (inner, 15 user contact layer). The method of mounting the absorbent core 40 between the top surface 50 and the bottom surface 30, as well as the method of attaching the bottom surface 30 to the top surface 50, is not critical and can be secured in many industrial applications such as gluing, hot sealing, etc. In a preferred embodiment, a plurality of spacing is provided. longitudinal adhesive tapes 35 substantially parallel to the longitudinal centerline 90 of the sheath 10. The adhesive used for the strips 35 is preferably a hot melt adhesive, 25 but may be any commonly available adhesive that is compatible with the various components of the disposable diaper 10. The longitudinal adhesive tapes 35 secure the upper surface 50 to the lower surface 30 at the points where the upper surface, the lower surface, and the adhesive tapes contact each other. The extent and location of the areas where the upper surface 50, lower surface 30, and longitudinal adhesive tapes 35 join depends on the distance between the longitudinal adhesive tapes 35 and the location, shape, and size of the absorbent core 40 between the upper surface 50 and the lower surface 30. The number of longitudinal adhesive tapes 35 and their distance from each other should be selected so that the upper surface 50 is sufficiently adhered to the lower surface 30 in the area between the outer edge 20 of the diaper and the outer edge of the absorbent core 40 and the longitudinal side edges 45.

35 melt-5 adhesives suitable for longitudinal adhesive tapes are supplied by Eastman Chemical Products Company, Kins-sport, Tennessee, and are sold under the trade name Eastobond A-3. The outer edge 20 of the sheath is preferably formed by the boundaries of the upper surface 50 and the lower surface 30. In this regard, it is preferred that the upper surface 50 and the lower surface 30 be substantially similar in shape and size so that their boundaries abut and thus form the outer edge 20 of the sheath. It should be noted that when using the described attachment method between the upper surface 50 and the lower surface 30, the upper surface 50 on the lower surface 30, whereby the absorbent inner part 40 closes between them. Instead of the method described above, the upper surface 50 can of course be attached to the lower surface 30 in other ways as well, e.g. the upper surface 50 can be attached to the lower surface 30 via a spacer (not shown), whereby the absorbent inner part 40 also closes between them.

As shown in the figures, the disposable diaper 10 includes a first or anterior lumbar portion 22 and a second or posterior lumbar portion 24. The anterior lumbar portion 22 extends from the leading edge 23 of the diaper 10 a certain distance inwardly toward the center of the diaper 10. The rearwardly extending edges 25 of the front lumbar portion 22 intersect the leading edges 28 of the shaped edges 28 of the sheath circumference 20. Likewise, the forward extending opposite edges 26 of the posterior lumbar portion 24 intersect the trailing edges of the shaped edges 28. Although the lengths of the edges 30 25 and 26 may vary in different embodiments of the sheath 10, these lumbar portions generally extend a distance of 1/4 toward the center of the sheath. .. 1/3 of the total length of the sheath. The lumbar portions 22 and 24 are those portions of the sheath 10 that, in use, surround the user's hip. On the other hand, the crotch portion C of the hook-35 is that portion between the anterior lumbar portion 22 of the diaper 10 and the posterior lumbar portion 24 that is in use located between a person's thighs. The length of the leg portion C is denoted in Figure 1 by the letter L. The other portions of the diaper 10 located between the anterior and posterior lumbar portions 22 and 24 and 5 on the other hand between the leg portion C cover the front and back of a person in use.

The absorbent core 40 may be any body that is generally compressible, comfortable, non-irritating to the wearer's skin, and capable of absorbing and retaining fluids. The absorbent core 40 shown in Figure 1 is formed of a single absorbent layer, but it is possible to form the core 40 by joining and / or laminating a plurality of absorbent layers. The absorbent core 40 is intended to absorb 15 and contain secreted fluid and can be made into a variety of sizes and shapes (e.g., rectangular, hourglass, etc.) and from a variety of liquid absorbent materials commonly used in disposable diapers (e.g., chopped wood dolls, cellulose wadding). suction foam or sponge, etc.). The total suction power of the absorbent core 40 should be matched to the estimated fluid load and the intended use of the diaper 10. The size and suction power of the absorbent core 40 can thus be varied according to the intended use, from the diaper for small children 25 to the diaper for adults.

The absorbent core 40 is shown in Figure 1 to be generally hourglass shaped and is intended for children weighing approximately 5 to 12 kg. The absorbent core 40 preferably consists of a wood wool board having a length of about 387.4 mm as measured from the longitudinal centerline 90, about 254 mm as measured across the front and rear end portions 42 and 44, and about 82.5 mm as measured across the narrowest portion of the crotch portion C. The suction capacity of the wooden manikin used in the absorbent core 40 is preferably such that it is capable of absorbing and containing about 8 to 16 g of liquid per grit of absorbent material. A typical diaper 10 for use in children thus weighs about 20 to 56 g. It should be noted, however, that the dimensions, shape and construction of the absorbent core 40 may be varied to suit different users from children to adults (the absorbent core may vary in size or have a wetting rate or may contain a polymeric gelling agent). Additional fibrous layers could also be used to improve the tensile strength of the absorbent core 40 (not shown) to reduce its tendency to crack, agglomerate, or ball when wet and further facilitate lateral transport of fluids, allowing fluid absorbed into the absorbent core 40 to distribute more evenly. Such additional layers are preferably shaped and sized for the absorbent core 40, but may be of different shapes and sizes if desired.

The absorbent core 40 is placed on the lower surface 30 and attached thereto in any known manner used in the manufacture of the diaper. The absorbent inner part 40 can, for example, be attached to the lower surface 30 by a uniform, continuous layer of air, an adhesive layer according to a certain pattern or a combination of adhesive lines and / or dots. It is preferred to use the aforementioned longitudinal adhesive tapes 35 to simultaneously attach both the absorbent core 40 to the lower surface 30 and the upper surface 50 to the lower surface 30.

The lower surface 30 is preferably a liquid impermeable material so that liquids 30 absorbed into the absorbent core 40 do not wet underwear, clothing, bedding and other items with which the disposable diaper 10 may come into contact. The preferred material for the lower surface 30 is a polyethylene film (e.g., polyethylene film number 8020 supplied by Monsanto Chemical Company) having a thickness of 35 to 0.012 to 0.051 mm, although other flexible, liquid-impermeable materials may equally well be used. The term "flexible" as used herein refers to materials that are flexible and easily adapt to different shapes of the human body. The lower surface 30 is preferably provided with an embossed and / or matt surface to make it more garmented and sensual. In addition, channels can be made in the lower surface 30 which allow vapors to escape from the absorbent core 40 but do not allow liquid to pass through.

As discussed above, the lower surface 30 comprises anterior and posterior lumbar portions 22 and 24 and opposing shaped edges 28 which give it an hourglass-like shape with contours extending from all sides of the absorbent core 40 beyond it and leaving a rim 27 around it. The rim 27 thus preferably extends completely around the contours of the absorbent core 40 and forms front and rear end strips across the outer ends of the lumbar portions 22 and 24 and opposite side strips adjacent opposite sides 20 of the absorbent core 40 longitudinally between the lumbar portions 22 and 24. The exact width of the rim 27 is not critical and may vary in the sheath, as shown in Figure 1. By way of example, however, the front and rear end strips 25 extending across the outermost ends of the lumbar portions 22 and 24 are typically about 39 mm or less in length (measured along the length of the sheath 10).

The topsheet 50 should be made of a flexible, relatively soft material that does not irritate the wearer's skin 30 and prevents direct contact between the absorbent core 40 and the wearer 10. In addition, the top surface 50 must be liquid permeable so that the secreted liquid can easily penetrate it as it passes towards the absorbent interior 40. The top surface 50 can be made of various materials such as natural fibers (e.g. wood fibers or cotton fibers), man-made fibers (e.g. polyester or polypropylene), a combination of natural and man - made fibers, or any reticulated foams or shaped films generally known in the art. A highly preferred material for the top surface 50 is a nonwoven fabric formed of polypropylene fibers of a certain length with a denier of about 1.5 (such as Hercules 151 type polypropylene supplied by Hercules Inc, Wilmington, Delaware). The length of the fibers is then about 10 15.9 mm. The top surface 50 can be made by any of a number of methods used in industry. The top surface 50 may be a woven fabric, nonwoven, braided or carded or similar material. The top surface 50 is preferably carded and thermally bonded by any method well known to those skilled in the art of nonwoven. In addition, the weight of the top surface 50 is preferably 15 to 21 g per square meter, the minimum dry tensile strength of at least 400 g / cm in the machine direction and the wet tensile strength of at least about 55 g / cm in the transverse direction to the machine.

The leg tensioners 60 are shown to be operatively associated with the longitudinal side strips of the sheath 10 so as to stretch the branch portion of the sheath 10 laterally outward in use. The term "join" as used herein means a structural connection of the branch tensioner 60 to the relevant side strip. In particular, it has been found that the leg tensioner 6Q should consist of one or more resilient members 65 extending from an attachment point 70, preferably located adjacent the longitudinal edge 45 of the absorbent core 40 in the region of the leg portion C of the sheath 10. Although the leg tensioner 60 may consist of only one resilient member 60, it is preferable to use at least two opposing resilient members 65 to make the outward lateral stretch in the leg portion C more uniform. From the attachment point 70, the branch tensioner 60 extends across the respective side strip to a point which sinks 89866 longitudinally outside the branch part C. The exact location of the attachment point 70 is not critical, but it has been found that to provide the most effective lateral stretch in the sheath portion 5 of the sheath 10, the attachment point 70 is most preferably located on the longitudinal side edge of the outer edge 45 of the absorbent core It has also been found important that the resilient members 65 extend from the point of attachment of the leg portion C to a point 70 located longitudinally outside the leg portion C. This structural requirement ensures that the desired lateral stretching is achieved by attaching the stretch member outside the leg portion C.

As shown in Figure 1, the leg portion C has a certain approximate length L in each embodiment of the sheath 10. Although the exact length L may vary in different embodiments of the sheath 10, it is recommended that the leg portion C be located approximately in the center of the sheath 10 and its leading edge 23 from the leading edge 23 of the sheath 10 approximately 35% of the total length D of the sheath 10 and the trailing edge 23 is about 50% of the length D of the sheath 10. In this regard, it is preferred that the leg portion C be located somewhat in front of the structural 25 of the sheath 10 to more closely match the anatomy of the human body. It is also recommended that the narrowest point of the absorbent core 40 be located approximately in the center of the crotch portion C.

To provide lateral stretch to the leg portion C 30, the attachment points 70 are located on each side strip of the sheath 10 adjacent the edge 45 of the absorbent core in the region of the leg portion C, as shown. Although the attachment points 70 need not be located at the narrowest portion of the absorbent core 40, it is recommended that these attachment points 35 be located near the center of the leg portion C so that the outwardly extending stretch is more evenly distributed over the leg portion. Similarly, although the branch tensioners 60 are shown to comprise two opposing resilient members 65 extending radially outwardly from the attachment points 70, an arbitrary number of resilient members 65 could extend from the attachment point 70 on each side strip of the sheath 10 to a longitudinally extending portion C in order to obtain the desired lateral stretching. The attachment point 70 could thus extend a plurality of resilient members 10 to a location outside the branch portion C. It should be remembered, however, that the purpose of these resilient members 65 is to provide lateral stretching in the leg portion C and thus must be located in the radial directions with respect to the attachment points 70 in order to function in this way. By "outward lateral stretching" is meant herein that the resultant stretching vector generated by the branch tensioners in use in the sheath of the invention should have an outwardly directed component with an outward direction and perpendicular to the longitudinal centerline (e.g., 90) or center axis of the sheath. For this reason, in the sheath 10 described and illustrated in the figures, the tension vectors generated by the individual resilient members 65 have a component extending outwardly toward the shape edge 28 of the sheath perpendicular to the centerline 90. Although the direction of the resilient members 65 can be varied by changing the angle B between them. a significant outwardly pointing component for providing outward stretching of the sheath 10.

The resilient members 65 are shown in Figure 1 extending radially outwardly from the attachment points 70 so as to form substantially V-shaped, resilient tensioners 60. In particular, the apex si-35 of the V-shaped tensioners coincides with a single securing line 70. This V-shaped structure is illustrated. by way of example only, and it has been found that such resilient members do not always need to extend outwardly with respect to the longitudinal centerline 90 of the sheath 10 to provide outwardly extending lateral stretch. As will be described in more detail below in connection with Figure 2, the resilient members 65 may be e.g. substantially parallel and at the same time parallel to the centerline 90 and still provide the desired lateral extension to the leg portion C. The length of the individual resilient members 65 is not critical as long as they are long enough , so that they extend from the point of attachment to a point 70 located longitudinally outside the branch portion C.

To create such an outwardly extending lateral stretch in the leg portion C, the leg clamps 60 are attached to the sheath 10 so as to tend to pull the leg portion C outward in use. When worn, the leg portion C of the sheath 10 thus has a flexible longitudinal portion. Although branch tensioners 60 can be attached to a sheath by any of a number of methods known in the art, a highly preferred sheath structure provided with elastic bands is described in detail in the aforementioned U.S. Patent 3,860,003. A method and apparatus for making a sheath with elastic members is further described in U.S. Patent 4,081,301, entitled "Method 25 and Apparatus for Continuously Attaching Discrete, Stretched Elastic Strands to Pretermined Isolated Portions on Disposable, Absorbent Producgs", issued to KB Buell on March 28, 1978 and to which reference is made in this regard. In this manner, the leg tensioners 60 engage the side strip of each of the two in a resiliently retractable manner so that the resilient members 65 effectively pull the longitudinal side strips of the sheath together when the sheath is normally released. In the preferred embodiment, the resilient members 65 are attached to each side strip of the rim 27 14 3 9 866 at a particular location on the lower surface as described and described. The adhesive used for this purpose should be flexible and sufficiently adhesive to allow the resilient members 65 to adhere to the lower surface 80 as the resilient members are stretched. The adhesive used for this purpose with satisfactory results is manufactured by Century Adhesives Corporation of Columbus, Ohio and sold under the tradename "Century 5227". The branch clamps 60 may be resiliently connected to the sheath 10 in any manner known or conceivable by those skilled in the art. For example, the resilient members 65 may be stretched prior to attachment to the lower surface 30, or alternatively, portions of the disposable diaper 10 may be compressed (e.g., by folding) prior to attaching the unstretched resilient member thereto.

The material or materials from which the resilient members 65 are made are not critical and may be any suitable resilient material, such as natural rubber or an elastomeric film, such as ethylene, propylene dimer, or polyurethane. Also, the width 65 of the resilient members 20 is not critical and can typically range from about 0.038 mm to 25.4 mm or more as needed. In addition to the adhesives, the resilient members 65 may be attached to the sheath by other known methods, such as ultrasonic welding or heat sealing. The recommended elastic member is made of natural rubber (L-1900 rubber compound marketed by East Hampton Rubber Thread Co.) and is approximately 6.35 mm wide and about 0.2 mm thick and generates 100 g of traction when stretched to 100% rest .

The sheath 10 further includes, as shown, external fasteners or strips 31 attached to the lumbar portion 24 near the trailing edge of the sheath 10 and holding the front and rear lumbar portions 22 and 24 overlapping each other when the sheath 10 is used. The sheath 10 is thus fitted over the wearer and secured around the pelvis. The external fasteners 31 should therefore be attached to both the posterior and anterior lumbar portions in such a way and with sufficient strength that they withstand the forces that tend to separate the lumbar portions from each other when using the 5 sheaths. Many alternative fasteners (e.g., velcro tapes, Velcro tapes, buttons, snaps, etc.) may also be used as fasteners 31. In a preferred embodiment, the fasteners 31 consist of tape strips, e.g., a Y-shaped tape, disclosed in U.S. Patent 3,848,594. entitled "Tape Fastening System for Disposable Diaper" and awarded to KB Buell on 19 November 1974 and to which reference is made in this regard.

As shown in Fig. 1, the attachment points 70 15 are preferably located opposite each other in the leg portion C and spaced laterally apart to provide sufficient outwardly extending lateral stretch to the leg portion of the sheath 10. It has been concluded that the width W should be at most about 20,153 mm in the sheath in order to achieve sufficient lateral stretching.

That is, if the lateral distance between the innermost points 70 of the opposite attachment points 70 of the sheath 10 is greater than about 153 mm, insufficient outward lateral tension is generated in the leg portion C of the sheath 10 and the advantages described above are not achieved. Both attachment points 70 could be located near the center of the leg portion C parallel to its centerline 90 (e.g., the width W would be equal to zero), but such placement is not recommended because the leg clamps 60 would then tend to compress the absorbent core from the region of the leg portion. To prevent such squeezing, it is preferred that the attachment points 70 be located adjacent the opposite longitudinal side edges of the outer edge 45 of the absorbent core 40, as shown in Figure 1.

16 89065

Figures 2 and 3 show partial, schematic cross-sectional views of previously known sheath structures without unique branch tensioners according to the invention. In particular, Fig. 3 shows a disposable diaper 5 with a simple pair of flexible leg openings E and an absorbent inner part A. In use, the flexible leg openings E tend to fit in the folds of the wearer's legs and without the branch tensioners according to the invention the absorbent inner and flexible leg openings 10 down and collapses from the crotch region. Such landing / collapse impairs the fit of the diaper and impairs its ability to contain secretions. Similarly, Fig. 4 shows a sheath of a known type with double elastic leg openings 15, which according to the figure include inner rubber strips e and outer rubber strips E '. As can be seen from Figure 3, the double rubber bands also tend to settle in the folds of the wearer's legs in the crotch region, allowing the diaper to lower / collapse considerably from the crotch region of the diaper. Figures 2 and 3 thus illustrate that the double rubber bands alone do not cause outward lateral stretching in the sheath, as they lack the branch tensioners according to the invention. As mentioned, the fit and binding ability of such diapers suffer considerably from this general tendency to descend and collapse from the crotch region.

Overcoming the descent / collapse forces that occur during use in the crotch region of the diaper distinguishes the diaper of the invention from other diapers. The result is 30 disposable diapers with significantly better tightness and fit. It should be noted that while apparently no flexible sheath structure can completely resist inward compression of the sheath crotch between the wearer's legs when held close together, the unique feature of the sheath of the invention is 17 '39066 to tend to return straight, with less shedding and compression of the wearer's feet. with movement and the tendency of the sheath to settle decreases.
