Description

FIELD OF TECHNOLOGY

The invention relates to an absorbent article with a longitudinal direction and a transverse direction and with two end edges extending in the transverse direction and two lateral edges extending in the longitudinal direction, and comprising a fastening structural member for securing the absorbent product, while the fastening structural member comprises a strip of material with a longitudinal direction and a transverse direction and with a first short end and a second long end, wherein said first short the end of the strip of material is firmly fixed in the absorbent article, and the strip of material contains a fastening device.

BACKGROUND OF THE INVENTION

Available absorbent products designed to absorb the released fluid organisms are made with a number of different designs. To absorb urine and excrement, as a rule, diapers or protective devices used for incontinence are used, made with a form that during use imitates a pair of underpants. Such diapers, needless to say, can be made as solid absorbent underpants that can be removed in the same way as a pair of ordinary underpants. However, a design of this type is best suited for use by people who can get up and can put on a diaper and take it off on their own. For young children and adults with reduced mobility and impaired balance, with incontinence, on whom the diaper is usually worn, and from which the diaper is usually removed by a caregiver or assistant, other types of diapers are often more practical. Another disadvantage of the diaper-panties is that they are characterized by a relatively small possibility of adjusting (regulating) their size.

For young children, the most common type of diaper is the one called the whole diaper (all-in-one diaper), which contains an absorbent body enclosed in an outer covering element and that is fastened together on the sides along the thighs of the baby. Bonding is usually carried out using special fastening devices located on the locking tabs. The fastening devices, which are usually used, are adhesive that glues when pressed, or devices in the form of hooks and loops. The locking tabs in most cases are fixed on the back of the diaper, at the side edges and next to the rear waist edge of the diaper, and these tabs are moved forward to the front of the diaper and attached to it. The diaper, as a rule, is made with a receiving surface of some type, designed for fastening devices on the locking tabs. For adhesive fixing tabs, some type of reinforcement of the outer covering element of the diaper is used, for example, in the form of a plastic strip, which allows fastening and opening without breaking. Fixing tabs with hook and loop devices are most often made with male parts (hook devices) of hook and loop devices and are attached to the corresponding female part, which may be a nonwoven fabric surface with fiber loops in which hooks can be securely hooked. Known locking tabs allow some control of the fit and size of the diaper, but they are not completely satisfactory in this regard. In particular, both the shape and girth of the body can vary significantly for different adult users, and known fastening devices provide only a limited possibility of regulation.

Another type of diaper that is widely used for adults with severe incontinence is a diaper held by a belt. Such diapers have a separate or integrated (integrated) belt with a diaper, which is fastened around the user's waist and from which the absorbent body of the diaper hangs. A diaper with a "built-in" belt usually has one half belt attached to the rear end of the diaper and protruding from the lateral edges of the diaper. When putting on the diaper, the belt is fastened around the waist of the user, with the diaper hanging down over the back of the user. After that, the front of the diaper is directed forward between the legs of the wearer and upward over the abdomen and is finally attached to the belt from edge to edge of the wearer's abdomen. If the belt is made with such a design that allows fastening along its entire width, it is possible to some extent adjust the size of the diaper due to the fact that the length or "size of the pelvic zone" can be changed depending on which near the edge of the belt - top or bottom - the diaper will be fixed. However, this regulatory ability is often insufficient, which means that even diapers with a belt must come in a number of different sizes.

Alternatively, the belt diaper may be held by a separate belt. Such a diaper is preferably worn to a greater or lesser extent similar to a diaper with a "built-in" belt. Thus, the diaper is attached with a fastening device of some type to the back of the belt, after which the belt is fixed around the user's waist. After that, the free end of the diaper is directed forward and upward on top of the abdomen of the wearer and attached to the belt so that the diaper and the belt together take on a shape similar to that of underpants. A diaper with a belt, made with a separate belt, provides the possibility of adjusting the dimensions to a slightly greater degree compared to a diaper with a "built-in" belt. In addition, the belt can be designed so that it can be used repeatedly. However, these diapers with a belt also do not allow changing their sizes sufficiently to satisfy the need for different sizes of the diaper for different users.

Consequently, there remains a need for an absorbent article that can be fastened together in the form of a panty-shaped article and in which fastening devices provide a significant degree of control over the size and fit of the article.

SUMMARY OF THE INVENTION

In accordance with the invention, an absorbent article of the type described in the introduction has been obtained, namely, comprising an attachment member for fastening the absorbent article together. The fastening structural element comprises a strip of material with a longitudinal direction and a transverse direction and with a first short end and a second short end, the first short end being firmly fixed in the absorbent article, and the strip of material contains a fastening device.

The product according to the invention is mainly characterized in that the fastening structural element is an extendable fastening structural element formed by a strip of material folded in a zigzag pattern along two laterally extending fold lines that divide the strip of material into a first end part at a first short end, a second end part on the second short end, and the middle part located between the end parts, and the first end part of the strip of material is attached to the middle the second part by a first breakable attachment, and the second end portion of the strip of material is attached to the middle portion by a second breakable attachment, and a fastening device arranged on the second end portion of the folded material strip, on a surface directed away from the middle portion.

Strong attachment means a permanent connection, which is not intended to break it neither under the action of forces that arise during the use of the absorbent product, nor under the action of active tearing. A solid mount usually cannot be broken without breaking the surrounding material.

The fastening structural element according to the invention can take two different positions when secured and makes it possible to choose between different fastening positions. In the first fixing position, the fastening structural element is used in the folded state as defined above. In order to obtain a second fastening position, it is necessary to destroy the damageable joints, which ensure the fixation of the folded zigzag strip of material of the fastening structural element in the folded state. This should be actively performed by the person securing the absorbent article around the user's torso. When the joints are broken, the strip of material is laid out to its full length, which means that the fastening devices will have a significantly greater reach than when the fastening structural element is folded. Various fixing positions can be used by caregivers to adjust the size and fit of the absorbent article individually for each person to care for.

In the case where the absorbent article is a one-piece diaper, the possibility of lengthening the fastening structural elements means that the width of the diaper can be adjusted within a larger interval than was previously possible. Instead, the absorbent article in the form of a diaper with a belt acquires greater adaptability in the longitudinal direction, as a result of which the diaper can be used for a larger group of users with different lengths of the pelvic part, i.e. different distances between the crotch and the waist. A diaper with a belt, of course, can also be adjustable with respect to its length around the circumference of the waist, if the belt tape is made with a zigzag folded fastening structural element in accordance with the invention.

The absorbent article may preferably be a diaper with a belt made with an elongated absorbent part and with a belt that holds the absorbent part. The absorbent portion preferably comprises an absorbent body enclosed in a cover member, wherein the cover member is formed, for example, by an inner liquid-permeable cover sheet and an outer liquid-tight back sheet. In addition, the absorbent part can be made with elastic devices along the lateral edges, through which receive tensile openings for the legs.

In accordance with one embodiment, the absorbent portion has a first end portion that is firmly attached to the belt, wherein the first end portion is preferably a rear end portion and a second end portion, and an extendable fastening structural member is firmly fixed to the second end portion and is configured to fixing it on the belt.

An extendable fastening structural element on the absorbent part may extend in the transverse direction of the product along a greater or lesser part of the end edge of the absorbent part. In such an embodiment, the fastening member may have a greater extent in the transverse direction than in the longitudinal direction. In the case where only one fastening structural element is used, it is preferably located at the end edge, centrally on the absorbing part.

However, it is preferable that at least two folded zigzag fastening structural elements are firmly fixed on the second end part and are made with the possibility of fixing them on the belt. In the case where the product has two extendable fastening structural elements, they are preferably located symmetrically on each side of the longitudinal center line of the product, in the area between the end edges and side edges of the absorbing part.

According to another embodiment, the absorbent part and the belt are separate parts of a diaper with a belt that are fastened together during use to form a component that looks like a pair of underpants. Such a diaper with a belt expediently has one or more extendable folded zigzag fastening structural elements on at least one end edge of the absorbing part. The belt may be a reusable belt that can be used again and again with new absorbent parts. Alternatively, the belt may be a disposable belt and, like the absorbent portion, is discarded after use. In such an embodiment, fastening devices on the fastening structural element or fastening structural elements at one end edge may be fastening devices of this type, which enable permanent fastening of fastening devices to the belt. However, it is preferable if the fastening structural element or fastening structural elements on at least one end edge provide the ability to detach or, if necessary, re-fasten the fastening devices on the belt. This design facilitates both the adjustment of the fastening of the diaper and the removal of the diaper after use.

The fastening structural element or fastening structural elements according to the invention can be located either on the inside of the absorbent article, which is the side facing the user during use, or on the outside of the article. For diapers with a belt, as a rule, it is preferable to place a fastening structural element or fastening structural elements on the inside of the diaper, since it will thus be easy to fix the absorbent part on the outside of the belt without any special manipulation. However, it is possible instead to place fastening structural elements on the outside of the absorbent part. In such an embodiment, fastening devices are fixed to the inside of the belt. For diapers with a belt made with a separate belt, when using which the rear fastening devices are first attached to the belt before placing the belt around the user's waist, placing these rear fastening devices on the outside of the absorbent part will not create inconvenience. It may even be an advantage that with this connection, the belt will keep the absorbent body pressed against the user's body during use. Another advantage of placing fastening structural elements on the outside of the absorbent article is that there will be less risk of rubbing or other types of discomfort, since the fastening structural elements are held at a certain distance from the user's body. This is a particular advantage when using mechanical fastening devices, such as hook and loop devices, which can be rigid and hard with a surface rubbing the skin.

The belt can also be made with one or more extendable folded zigzag fastening structural elements designed to secure the belt around the user's waist. This embodiment means that the width of the diaper can be adapted to the girth of the user's body.

In addition, the product may contain an additional fastening structural element in the form of a double-folded locking tab, which is formed by an elongated strip of material having a first end part that is firmly attached to the absorbent product, and a second end part, which is folded inwardly to the first end part and attached to by means of a releasable connection, and a fastening device is located on the second end part on that surface which is directed to the first end part. Such a locking tab provides additional fastening, if desired. The locking tab may be left in its folded state, and in this case, it does not contribute to fixing the absorbent article. However, if the disconnectable connection is broken, the fastening device will be open to impact and the locking tab can be used as an addition to other fastening structural elements of the product. For example, such a locking tongue can be used to avoid gaps between the belt and the absorbent part.

The invention can also be applied to whole diapers. In this case, the absorbent product is a diaper with two end edges and two side edges and has two end parts and an intermediate crotch part, and is made with an extendable fastening structural element, firmly attached to each side edge on one end part, while fastening structural elements made with the possibility of interaction with the receiving device at the second end part.

Destructible joints on a folded zigzag, extendable fastening structural element according to the invention or on a double folded, fixing tongue may contain destructible welds. In addition, there is the possibility of performing fracture compounds in the form of a fracture adhesive joints. An adhesive suitable for forming such joints is a dry structural adhesive that will not be sticky after fracture of the joint. One example of such an adhesive is Dispomelt® 2000. Destructible joints must be strong enough to hold the folded zigzag fastening structural element together when the carer chooses not to unfasten the fastening structure. At the same time, the seams should provide the possibility of their easy destruction by means of manual force if the full length of the fastening structural elements is to be used. The person skilled in the art will not have any difficulty in obtaining joints with appropriately adapted joint strength provided that he uses his knowledge regarding the adhesion force (adhesion strength) of various adhesives and the tensile and shear forces that occur during use of the diaper .

Of course, it is also possible to use types of fastening devices other than fastening devices with glue, for example various types of mechanical fastening devices such as a hook and eyelet, a button and buttonhole, buttons and devices in the form of hooks and loops. In this case, special preference is given to devices in the form of hooks and loops. By means of hook and loop devices, applicants understand all types of fastening devices in which the male part, made with hooks or protrusions, interacts with the female part and is captured by the female part, which is made with loops or loops of fibers. When using devices in the form of hooks and loops, the male part is preferably located on a folded zigzag, extendable fastening structural element and is configured to interact with a receiving surface forming the covering part of the device in the form of hooks and loops. Combinations of mechanical fasteners and fasteners provided with glue are also possible within the scope of the invention.

The folded strip of material in the fastening structural element according to the invention preferably consists of a flexible material with a high tensile strength. Suitable materials are plastic films, non-woven materials and various types of laminates from these materials. In the case where the fastening structural element must rest on the skin of the user during use, it is advisable that the material in the strip of material has a soft surface on the side facing the user. In addition, it may be appropriate for the material to be breathable, that is, to allow moisture and water vapor to pass through it. Non-woven materials, as a rule, have a soft surface, provide the possibility of moisture passing through them and do not stick to the skin. It is also advisable that the strip of material is easily bent and has soft edges so that there is minimal risk of rubbing the skin of the user. The material of the strip of material may be substantially non-elastic so that it will not stretch during use. Alternatively, the material may be extensible, in which case it is preferably elastically extensible. Such an embodiment makes it possible to continuously control the length of the strip of material during use of the absorbent article.

In order to facilitate the separation of destructible joints, the fastening structural element can be formed with a catch tongue at the second short end of the strip of material. Such a catching tongue can expediently be formed by the edge zone of a strip of material that is free of joints.

The fastening member can be attached to the cover sheet of the absorbent article in such a way that the fastening member in its folded state is fully placed within the surface of the cover sheet. Alternatively, the fastening member may be firmly fixed to the edge of the absorbent article so that the fastening member will protrude outward from the edge of the article even when folded. In such an embodiment, the fastening member may be firmly fixed to the cover sheet of the article or between cover sheets. It goes without saying that the fastening structural element can be firmly fixed in some element located between the covering sheets. The fastening is expediently performed by gluing, welding or stitching.

DESCRIPTION OF EMBODIMENTS

Figures 1 and 2 show a diaper 100 with a substantially rectangular flat shape. The diaper 100 is shown from the side that should be facing the user during use. The diaper comprises in a conventional manner a liquid-permeable cover sheet 101, a liquid-impermeable cover sheet 102, and an absorbent body 103 sandwiched between the cover sheets 101, 102.

The liquid permeable cover sheet 101 has the same shape as the absorbent body 103. The liquid impermeable cover sheet 102 is also made with a shape similar to the shape of the absorbent body. However, the cover sheets 101, 102 are slightly longer in plane than the absorbent body 103 and form a connecting edge 104 that protrudes around the periphery of the absorbent body 103. The cover sheets 101, 102 are connected to each other around the absorbent body, for example, by means of glue , stitching or welding by ultrasonic welding or heat welding. In addition, one or both of the cover sheets 101, 102 can be attached to the absorbent body 103, for example, by means of glue, stitching, grinding or ultrasonic welding or heat sealing.

The liquid permeable cover sheet 101 is a corresponding sheet of the usual type and, therefore, may consist of any liquid permeable material suitable for the purpose. Examples of such materials include various types of thin non-woven fabric, perforated plastic films, liquid permeable mesh material, foam material or the like. The liquid-permeable cover sheet 101 may be formed of two or more different materials to enable the cover sheet to perform various functions. For example, it is a common situation to place the liquid transporting layer inside with respect to the liquid receiving layer. It is also known to place various types of materials on different parts of the diaper surface facing the user during use. Thus, a material with good accepting ability can preferably be located in that part of the diaper, which is expected to be first wetted by most of the fluid released by the body, while sections of the covering sheet located at some distance from the zone that is wetted first, can be performed with a barrier function to prevent leakage of absorbed fluid from the diaper.

It is not significant for the invention that the liquid permeable cover sheet 101 is a separate sheet of material, and instead, the cover sheet 101 may be the surface of the absorbent body 103 of the diaper 100.

The liquid impervious cover sheet 102 may also be made of any suitable material available. Particularly preferred materials are thin liquid-impermeable plastic films, a non-woven material or a multilayer material that has been coated with a liquid-impermeable material such as wax, resin, adhesive or the like. It is also possible to use laminates made of liquid impervious materials. For example, it may be desirable to form the back of the diaper with an outer sheet of textile type, for example with a sheet of non-woven material. Such a non-woven material provides a soft, skin-friendly surface of the textile material and provides advantages such as a high level of comfort for the user, a high degree of friction and therefore better retention on a garment worn over the diaper. In addition, it is often believed that a surface such as a surface of a textile material has an aesthetically attractive appearance. It is also preferred that the liquid-impermeable cover sheet 102 is breathable, that is, allows gas and water vapor to pass through the sheet.

The absorbent body 103 can also be made in the usual way and from conventional materials. Absorbent materials suitable for use in the absorbent body 103 include, for example, fluff pulverized pulp, absorbent bonded fibrous sheets, tissue paper layers, absorbent foam, peat, or the like. The absorbent body 103 may also preferably contain polymers with ultra-high absorbency, that is, polymers that are capable of absorbing liquid in an amount many times greater than their own mass, and form a liquid containing gel. Superabsorbents are usually present in the form of particles, flakes, fibers, granules or the like. The ultra-high absorbency material may be provided separately or in combination with another absorbent material and may be applied as layers or may be used as a mixture with other materials such as cellulosic fibers or synthetic fibers.

As already mentioned, the diaper 100 in FIGS. 1 and 2 is substantially rectangular in shape and has two rectilinear lateral edges 105, 106 and two similarly rectilinear end edges 107, 108. The diaper can be divided into the front 109. the back portion 110 and the intermediate crotch portion 111.

Elastic devices 112, 113 are located along the lateral edges 105, 106 and form leg gum when using the diaper 100. Suitable elastic devices are various types of elastic threads, tapes, elastic non-woven materials, elastic foam material or similar materials.

The diaper 100 is additionally made with a two-piece belt 114a, b, which is located so that half of the belt 114a, b protrudes perpendicularly from each side edge 105, 106 at the rear end edge 108 of the diaper. The belt halves 114a, b are composed of strips of soft and flexible material. Suitable materials are non-woven materials or laminates of materials consisting of one or more layers of non-woven material, plastic film, or the like. Thus, the belt halves 114a, b may contain layers of materials, the main purpose of which is to give the belt some predetermined property, such as increased softness and comfort, increased tensile strength, more aesthetically attractive appearance, some elasticity, some absorption capacity and etc. The belt 114a, b is further provided with hinge devices 115 located on the outside of the belt, that is, on the surface facing away from the user during use. In figure 1, the outer side is directed away from the beholder. Such hinge devices 115 may be formed in a non-woven, knitted or cast material, or may consist of loops of fibers in a non-woven material. As shown in the example, the devices 115 in the form of loops can be located on the entire outer side of the belt 114a, b or can be located only in special areas of bonding intended for fastening to the corresponding devices in the form of hooks.

In order to ensure that the diaper 100 can be fastened together during use to create a panty-like garment, the diaper is further provided with fastening devices 116, 117, 118, which have hooks 119. The fastening device 116, made with hooks, is located on the free end 120 of one half of the belt 114a, on a surface directed away from the device 115 in the form of loops. The fastening structural elements 117, 118 are also located in the corners between the side edges 105, 106 and the front end edge 107. The fastening structural elements 117, 118 have hook-shaped fastening devices 119 on the surface, which is directed towards the viewer in FIG. 1, that is, on the surface facing the user while using the diaper.

In this regard, it is understood that the hook devices encompass all existing types of hooks and protrusions that can engage in loops or fiber loops on the loop device 115.

During use, the diaper 100 is fixed around the lower body of the wearer and takes on the shape shown in FIG. It is fastened together by the way that the free end parts 120, 121 of the two belt halves 114a, b are passed around the user's waist and the hook fastening device 116 located on one half of the belt 114a is secured in fastening loops on the other half of the belt 114b. After that, the front end edge 107 of the diaper is moved forward between the legs of the wearer and fastened by means of fastening devices 119 in the form of hooks located on the fastening structural elements 117, 118 to the device 115 in the form of loops located on the belt 114a, b.

Figures 3a and 3b show enlarged views of a fastening structure 300 according to the invention. In Fig. 3a, the fastening member 300 is shown locked in a zigzag state, and in Fig. 3b, the fastening member is shown in a partially unfolded state. The fastening structural member 300 comprises a strip of material 330 having a first end edge 331, a second end edge 332, a first lateral edge 333 and a second lateral edge 334. In addition, the strip of material 330 is divided by a first fold line 335 and a second fold line 336 into a first end portion 337, a second end portion 338 and a middle portion 339 located between the end portions 337, 338. The first end portion 337 is firmly fixed to the absorbent article 340, for example, by gluing or welding.

In the folded state shown in FIG. 3a, the middle portion 339 of the strip of material 330 is attached to the first end portion 337 by a first breakable joint 341. The joint 341 may be adhesive, for example, as a glue strip, or the joint may be formed by welding. On figa and b, the connection 341 is shown in the form of a rectangular zone at the first end edge 331 of the strip 330 of material. However, in an alternative embodiment, it is possible to place the fastening elements in the form of some pattern on most of the surfaces of the first end part 337 and the middle part 339 facing each other. Such fastening elements arranged in a certain way can, of course, also be provided for the entire length of all connected (bonded) surfaces.

Accordingly, facing each other, the surfaces of the middle portion 339 and the second portion 338 are joined together by a second fracture joint 342.

The fastening structural element 300 is made with a fastening device 343. The figure shows as an example the surface of the connection type of hooks and loops provided with devices in the form of hooks. However, there is also the possibility of using any other type of fastening device, such as touch and close surfaces (Velcro) with devices in the form of loops, glue, buttons, buttons, hooks and loops, etc.

At the other end edge 332 there is a zone that is free of fasteners 343 and joints. This area serves as a gripping tongue 344 when the fastening member must be unfolded to its second fastening position.

In the case where the fastening structure 300 is used to fasten the absorbent article together, the fastening structure can be used in the folded state shown in FIG. 3 a. However, if the user of the absorbent article has a body shape and / or a body size that requires a greater reach of the fastener, the fracture joints 341, 342 can instead be broken and the fastener can be expanded to the full length of the strip of material, as shown in fig.3b. For the diaper 100 with the belt shown in FIGS. 1 and 2, this means that the diaper will have a large length in the downward direction around the user's crotch zone when the fastening members 117, 118 located at the front edge 107 of the diaper are unfolded. Accordingly, portions 114a, b of the belt of the diaper 100 can be extended around the waist of a person with a larger waist circumference when the fastening member 116 located on the belt is folded out.

The diaper 400 shown in FIG. 4 is shown in a bent state together with a completely continuous belt 414 and accordingly comprises a liquid permeable cover sheet 401, a liquid permeable cover sheet 402 and an absorbent body 403 enclosed between the cover sheets 401, 402. The diaper 400 is rectangular, with a front end portion 409 and a rear end portion 410, and an intermediate crotch portion 411. In addition, the diaper has two side edges 405, 406 that form openings around the user's legs when the diaper the nickname is located on the user, and the front end edge 407 and the rear end edge 408, which together form the waist edge of the diaper during use. In addition, the diaper 400 has elastic devices 412, 413 located along the curved side edges 405, 406 and designed to assemble the diaper together in assemblies around the legs of the user so that an impermeable seal is obtained around the legs.

To ensure that the diaper 400 can be fastened together during use to create a panty-like garment, the diaper is further provided with fastening structural elements 416, 417a, b, 418a, b having fastening devices 419. Fastening structural elements 417a, b , 418a, b are located in the corners between the side edges 405, 406 and the front end edge 407 and the rear end edge 408. The fastening structural elements 417a, b, 418a, b have hook-shaped fastening devices 419 designed to fastening to the outer side of the belt 414.

In addition, the diaper 400 comprises an additional fastening component in the form of a double-folded locking tab 445 on each end edge 407, 408. As shown in detail in FIGS. 5a and b, the locking tab 445 is formed by an elongated strip of material 446 having a first end portion 447. firmly attached to the diaper 400, and the second end portion 448, folded inwardly to the first end portion 447 and attached to it by means of a disconnectable joint 449, for example, made in the form of an adhesive joint or weld. The fastening device 450 is located on the second end part on that surface, which on the folded strip 446 of the material is directed to the first end part. Such a locking tab provides additional fastening, if desired. The locking tab can be left in its folded state, and in this case it does not contribute to the fastening of the diaper 400. However, if the disconnectable connection is broken, as shown in FIG. 5b, the fastening device 450 will be open to impact and the locking tab can be used in as a complement to other fastening structural elements 417a, b, 418a, b of the product. A locking tab 445 may be used to prevent gaps between the belt and the absorbent portion of the diaper.

When putting on the diaper shown in FIG. 4, the procedure will be essentially the same as when putting on the diaper of FIGS. 1 and 2. The back of the diaper 410 is preferably first attached to the belt 414 using the rear fastening members 417b, 418b. These fastening structural elements may be folded or may be unfolded, if desired. Thereafter, the belt 414 is secured around the waist of the wearer by means of the fastening member 416, and finally, the diaper front 409 is moved forward and up between the legs of the wearer and secured to the belt 414 by the front fastening members 417a, 418a. Like the fastening structural element 416 on the belt 414, the front fastening structural elements 417a, 418a can also be used in their folded state or in their unfolded state.

The diaper 600 of FIG. 6 is shown on the side that faces the user during use and is a one-piece type diaper. The diaper is in principle the same construction as the diapers described above, and comprises a liquid permeable cover sheet 601, a liquid impermeable cover sheet 602, and an absorbent body 603 enclosed between the cover sheets 601, 602. The diaper 600 has essentially hourglass shape, with the front end part 609 and the rear end part 610, and the intermediate, narrower crotch part 611. In addition, the diaper has two curved lateral edges 605, 606, which are designed to form rounded holes for woks the user's leg circle when the diaper is on the user, and the front end edge 607 and the rear end edge 608, which together form the waist edge of the diaper 600 during use. In addition, the diaper 600 has elastic devices 612, 613 located along the curved side edges 605, 606 and designed to collect the diaper in the assembly around the legs of the user so that an impermeable seal is obtained around the legs. An additional elastic device 651 is located along the rear end edge 608 of the diaper and forms a waist elastic when using the diaper.

To ensure that the diaper can be fastened together to create a garment similar to underpants, folded in a zigzag fashion, extendable fastening structural elements 617, 618 are arranged so that even in their folded state they protrude from the side edges 605, 606 at the rear end edge 608 The fastening structural elements 617, 618 are shown fastened to the liquid-permeable covering sheet 601. However, it is possible to fasten the protruding fastening structural elements 617, 618 instead of liquid-permeable cover sheet 602 or between cover sheets 601, 602.

When putting on the diaper shown in FIG. 6, the diaper is placed so that the crotch portion 611 is between the legs of the user, and the front and rear parts 609, 610 are directed upward and fastened together using extendable fastening structural elements 617, 618. Fastening structural elements 617 , 618 are fixed to a receiving area 652 located at the front. As in the previously described embodiments, the fastening structural elements 617, 618 can be used either in their folded state, as shown in Fig.6, or when folding them to their full length. Instead of using a special receiving area 652 for fastening structural elements 617, 618, it is possible to fasten fastening structural elements 617, 618 directly on the outer surface of the diaper. If the fastening structural elements 617, 618 contain fastening devices in the form of hook-shaped devices 619, it is advisable that in this embodiment, the outer surface of the diaper was a non-woven material.

The invention should not be construed as limited by the illustrative embodiments described herein. In particular, it is possible to change the shape of the described diapers, as well as the composition of the absorbent body and other components that are not important for fastening.
