Absorbent article having disposal fastening means

CROSS-REFERENCE TO RELATED APPLICATIONS

0001The present application is a continuation of international application no. PCT/SE2005/000821, filed on Jun. 1, 2005, the entire contents of which is incorporated herein by reference.

TECHNICAL FIELD

0002The present invention refers to an absorbent article such as a diaper, a pant diaper, a sanitary napkin or incontinence guard, comprising an absorbent core disposed between an inner coversheet and an outer coversheet, said article further comprising at least one disposal fastening means which is directly or indirectly joined to the outer coversheet, said disposal fastening means having a fastening element adapted to fasten to at least a portion of the outer coversheet which allows the article to be secured in a configuration that provides a convenient disposal after said article has been used.

BACKGROUND OF THE INVENTION

0003After use, absorbent articles are usually folded or rolled up so that the soiled portion is wrapped inside for disposal. In order to prevent the soiled article unfolding and to keep the soiled portion inside, it is desired that a so-called “disposal fastening means” is arranged to keep the article in the folded or rolled-up state under disposal. For a diaper having fastening means in the form of adhesive tape tabs or hook-and-loop type fasteners for fastening the diaper about the waist of the wearer, this fastening means may also be used as the disposal fastening means. However, other articles, particularly pant diapers, require special disposal fastening means, usually comprising a fastening element, for example an adhesive or a mechanical fastening element, which is fixed at one end to the front or rear of the article and folded up, so that in normal use the adhesive or the mechanical fastening element is brought in an unexposed position. The strip may be unfolded so as to expose the fastening element when it is desired to use it as a disposal fastening means.

0004EP-A-1 121 917 discloses a pant diaper having a disposal fastening means in the form of tape strips arranged in the vicinity of the side edges of the diaper. Each tape strip comprises two portions, a first portion extending longitudinally in parallel to the side edges and a second portion extending from a predetermined region of the first portion longitudinally or transversely of the diaper. The disposal fastening means is said to be adapted to hold the diaper in its rolled up state for disposal without leakage through the waist- or leg-openings.

0005International patent application PCT/SE2004/002026 discloses a pant-type absorbent article comprising at least one fastening means disposed in the side joint region between the joined side edges of the article. Upon tearing the side joint region, the fastening means is exposed.

0006US 2003/0153891 discloses an absorbent article having a disposal fastening means, said disposal fastening means including visible indicia. These indicia make it easier to locate the disposal fastening means, and may provide instructions to a user or caregiver.

0007US 2002/0065500 describes a plastic bag used for disposal of diapers which is located directly on the diaper and contained within a tearable enclosure on the diaper. When disposal of the diaper is required, the enclosure is torn open, the plastic bag pulled out and the soiled diaper inserted into the plastic bag.

0008EP 0 623 330 discloses a shorts-type diaper provided with a tape fastener intended to fasten the used diaper when discarding. EP00732094 discloses a similar article, in which the tape fastener is elastic.

0009JP 2002 045401 teaches a method of fixing a folded disposal tape to the backsheet of a diaper, using an adhesion layer to keep the tape folded while the article is being worn.

0010Many of these known disposal fastening means may be opened and even removed by mistake by the wearer or caregiver before the article is removed for disposal. This is particularly a problem for babies, who can remove a disposal fastening means attached to their diaper, thus making it ineffective as a fastening means. The disposal fastening means may also be opened under movements between a diaper and surrounding clothing and can then stick to the clothing. Untimely opening or removal of the disposal fastening means can lead to it becoming dirty or damaged, thus reducing its fastening ability.

OBJECT AND SUMMARY

0011One object of the disclosure is to provide an absorbent article having a disposal fastening means that reduces the risk of being opened by mistake before the article is ready for disposal. It is of particular interest to provide a disposal fastening means which draws less attention and is more discrete, so that babies show less interest in it. It is desirable to provide a disposal fastening means which is concealed and not immediately accessible, thus minimizing the risk of undesirable opening or removal.

0012An absorbent article of the type mentioned above has a disposal fastening means that is covered by a material layer. This material layer has a surface area such that it extends beyond the disposal fastening means, and is attached to or forms an integral part of the outer coversheet so as to keep the disposal fastening means hidden when not in use. The material layer is releasable from the outer coversheet so as to expose the disposal fastening means for use.

0013According to one aspect, the material layer is provided with perforations, breakable seals or the like for releasing it from the rest of the outer coversheet and thus exposing the disposal fastening means.

0014In another embodiment, the outer coversheet is a laminate comprising a garment facing layer and at least one additional layer located on the inside of the garment facing layer. In this embodiment, the material layer may be an integral part of the garment facing layer of the outer coversheet, and the garment facing layer may be perforated around at least a part of the circumference of the material layer.

0015According to a further embodiment, the material layer is separate piece of material which is joined to the outer coversheet by a breakable seal. The breakable seal may comprise welds, glue sites, etc. which join the material layer to the outer coversheet.

0016In a preferred embodiment, the material layer is of a composition and structure such that it closely resembles the garment-facing surface of the outer coversheet, especially a nonwoven material or plastic film. Furthermore, the outer coversheet according to the invention may comprise nonwoven material in at least the garment-facing surface thereof.

0017The fastening element of the disposal fastening means may be a hook portion of a hook-and-loop type fastener, or alternatively an adhesive tape tab. In one embodiment, the disposal fastening means is folded under the material layer.

0018The disposal fastening means may be joined to the material layer. Alternatively, the material layer is an integral part of the outer surface of the disposal fastening means.

0019In a preferred embodiment, the disposal fastening means comprises an elastic material such that—when not under tension—the disposal fastening means lies hidden under the material layer but can be extended under tension.

0020The disposal fastening means is of particular interest when the article is a pant-type absorbent article. This is because such articles do not have side-fastening tape tabs, which are otherwise used to keep the rolled-up article in a packaged state for disposal. The disposal fastening means is preferably located on the front or back portions of such a pant diaper. Desirably, a pattern is printed on the garment facing surface of the outer coversheet and at least a part of the pattern is located on the material layer.

DEFINITIONS

0000Absorbent Article and Pant Type Absorbent Article

0021The term “absorbent article” refers to products that are placed against the skin of the wearer to absorb and contain body exudates, like urine, feces and menstrual fluid. The disclosure mainly refers to disposable absorbent articles, which means articles that are not intended to be laundered or otherwise restored or reused as absorbent articles after use. The disclosure is particularly of relevance to pant-type absorbent articles, which have a defined waist opening and a pair of leg openings and which are pulled onto the body of the wearer by inserting the legs into the leg openings and pulling the article up over the waist. Examples of such pant-type absorbent articles are pant diapers, sanitary pants and incontinence pants worn by incontinent adults. Pant-type absorbent articles usually comprise a front portion, a crotch portion and a back portion, said front and back portions being joined to each other along two opposite longitudinal side edges to define a waist-opening and a pair of leg-openings.

0000Inner Coversheet

0022The term “inner coversheet” refers to the liquid permeable material sheet forming the inner cover of the absorbent article and which in use is placed in direct contact with the skin of the wearer. The inner coversheet can comprise a nonwoven material, e.g. spunbond, meltblown, carded, hydroentangled, wetlaid etc. Suitable nonwoven materials can be composed of natural fibers, such as woodpulp or cotton fibres, man-made fibres, such as polyester, polyethylene, polypropylene, viscose, rayon etc. or from a mixture of natural and man-made fibres. The inner coversheet material may further be composed of tow fibres, which may be bonded to each other in a bonding pattern, as e.g. disclosed in EP-A-1 035 818. Further examples of inner coversheet materials are porous foams, apertured plastic films etc. The materials suited as inner coversheet materials should be soft and non-irritating to the skin and be readily penetrated by body fluid, e.g. urine or menstrual fluid. The inner coversheet may further be different in different parts of the absorbent article.

0000Outer Coversheet

0023The outer coversheet refers to the liquid impervious material forming the outer cover of the absorbent article. The outer coversheet can comprise a thin plastic film, e.g. a polyethylene or polypropylene film, a nonwoven material coated with a liquid impervious material, a hydrophobic nonwoven material, which resists liquid penetration, or a laminate of a plastic film and a nonwoven material. The outer coversheet material may be breathable so as to allow vapour to escape from the absorbent core, while still preventing liquids from passing therethrough. Examples of breathable outer coversheet materials are porous polymeric films, nonwoven laminates of spunbond and meltblown layers and laminates of porous polymeric films and nonwoven materials. Preferably, the outer coversheet comprises nonwoven material in at least the garment-facing surface thereof.

0000Absorbent Core

0024The “absorbent core” is the absorbent structure disposed between the two coversheets of the absorbent article. The absorbent core can be of any conventional kind. Examples of commonly occurring absorbent materials are cellulosic fluff pulp, tissue layers, highly absorbent polymers (so called superabsorbents), absorbent foam materials, absorbent nonwoven materials or the like. It is common to combine cellulosic fluff pulp with superabsorbent polymers in an absorbent core. Superabsorbent polymers are water-swellable, water-insoluble organic or inorganic materials capable of absorbing at least about 20 times their own weight of an aqueous solution containing 0.9 weight percent of sodium chloride. Organic materials suitable for use as superabsorbent materials can include natural materials such as polysaccharides, polypeptides and the like, as well as synthetic materials such as synthetic hydrogel polymers. Such hydrogel polymers include, for example, alkali metal salts of polyacrylic acids, polyacrylamides, polyvinyl alcohol, polyacrylates, polyacrylamides, polyvinyl pyridines, and the like. Other suitable polymers include hydrolyzed acrylonitrile grafted starch, acrylic acid grafted starch, and isobutylene maleic anhydride copolymers and mixtures thereof. The hydrogel polymers are preferably lightly cross-linked to render the material substantially water insoluble. Preferred superabsorbent materials are further surface cross-linked so that the outer surface or shell of the superabsorbent particle, fibre, flake, sphere, etc. possesses a higher crosslink density than the inner portion of the superabsorbent. The superabsorbent materials may be in any form which is suitable for use in absorbent composites including particles, fibres, flakes, spheres, and the like.

0025A high liquid storage capacity is provided by the use of high amounts of superabsorbent material. For an absorbent core comprising a matrix of hydrophilic fibres, such as cellulosic fibres, and superabsorbent material, the proportion of superabsorbent material is preferably between 10 and 90% by weight, more preferably between 30 and 70% by weight.

0026It is conventional for absorbent articles to have absorbent cores comprising layers of different properties with respect to liquid receiving capacity, liquid distribution capacity and storage capacity. The thin absorbent bodies, which are common in for example baby diapers and incontinence guards, often comprise a compressed, mixed or layered structure of cellulosic fluff pulp and superabsorbent polymers. The size and absorbent capacity of the absorbent core may be varied to suit different uses, such as infants or adult incontinent persons.

0027The absorbent core may further include an acquisition distribution layer placed on top of the primary absorbent body, which is adapted to quickly receive and temporarily store discharged liquid before it is absorbed by the primary absorbent core. Such acquisition distribution layers are well known in the art and may be composed of porous fibrous wadding or foam materials.

0000Disposal Fastening Means

0028The terms “disposal fastening means” or “disposal fastener” refer to a fastening means or fastener such as a strip of material which comprises a fastening element such as an adhesive tape or a mechanical fastening means in the form of hook members. The disposal fastening means is arranged such that it can fasten to the outer coversheet to keep the absorbent article in the folded or rolled up state after disposal thereof.

DESCRIPTION OF PREFERRED EMBODIMENTS

0039As previously mentioned, the absorbent article <b>10</b> shown in <figref idref="DRAWINGS">FIG. 1</figref> (in this case a pant diaper) comprises an absorbent core <b>12</b> which is disposed between an inner coversheet <b>14</b> and an outer coversheet <b>16</b>. The disclosure primarily relates to pant type absorbent articles, which have a defined waist opening <b>15</b> and a pair of leg openings <b>17</b> and which are pulled onto the body of the wearer by inserting the legs into the leg openings and pulling the article up over the waist. Examples of such pant type absorbent articles are pant diapers, sanitary pants and incontinence pants worn by incontinent adults. The pant-type absorbent article comprises a front portion <b>30</b>, which is the part of the article that in use is intended to extend over the stomach and front hip area of the wearer. The article also comprises a back portion <b>34</b>, which is the part of the article that in use is intended to extend over the back and the rear hip area of the wearer. The crotch portion <b>32</b> of a pant-type absorbent article is the part of the article that in use is intended to extend through the wearer's crotch area, between the legs. The front and back portions <b>30</b> and <b>34</b> may have different material composition than the crotch portion <b>32</b>.

0040The lateral side edges of the front <b>30</b> and back <b>34</b> portions are joined to each other to form side seams <b>25</b>, wherein the article assumes a pant-like shape having the aforementioned waist opening and leg openings. The front and back portions are joined along said side seams <b>25</b>, for example by adhesive, ultrasonic welding, heat sealing or the like. The front and back portions <b>30</b> and <b>34</b> can either be joined along their side edges with the inner coversheet <b>14</b> facing inwards in the side seams <b>25</b>, as is shown in the drawings. Alternatively they are joined in an overlapping manner, with the inner coversheet <b>14</b> of either the front <b>30</b> or back <b>34</b> portion facing the outer coversheet <b>16</b> of the opposite portion.

0041The waist opening <b>15</b> and at least a part of the leg openings <b>17</b> are usually elasticized. The elastification is usually accomplished by a plurality of elastic members <b>27</b>, such as elastic threads, which are contractably affixed between the outer coversheet <b>16</b> and the inner coversheet <b>14</b>. Alternatively elastic materials, such as elastic laminates, may be used to form the front <b>30</b> or back <b>34</b> portions in those areas where elasticity is desired.

0042The article further comprises at least one disposal fastening means <b>18</b> as described above. The article may, for example, comprise two, three or more disposal fastening means, but in the interests of economy, only one or two disposal fastening means are usually present. The disposal fastening means <b>18</b> may be formed from any suitable material. Furthermore, a material layer <b>22</b> comprising nonwoven material will be well-concealed against an outer coversheet of nonwoven material, which is the material of choice for the outer coversheet. Typically, the disposal fastening means <b>18</b> is located on the front <b>30</b> or back <b>34</b> portion of the pant diaper.

0043The disposal fastening means <b>18</b> is directly or indirectly attached to the outer coversheet <b>16</b>, usually via one end of the disposal fastening means <b>18</b>. By “directly or indirectly” is meant that the disposal fastening means <b>18</b> may be attached to the outer coversheet itself, or that one or more layers of material may be present between the disposal fastening means <b>18</b> and the outer coversheet <b>16</b>. Attachment of the disposal fastening means <b>18</b> to the outer coversheet <b>16</b> may be via glue or welds, but should be sufficiently strong that the disposal fastening means <b>18</b> is not easily separated from the article when pulled by hand.

0044The disposal fastening means <b>18</b> has a fastening element <b>20</b> adapted to fasten to at least a portion of the outer coversheet <b>16</b>. The fastening element <b>20</b> allows the article to be secured in a configuration that provides a convenient disposal after said article has been used. This may be a rolled-up or folded configuration. The choice of fastening element <b>20</b> depends on the nature of the outer coversheet <b>16</b>—if the outer coversheet <b>16</b> is a plastic film, a suitable fastening element <b>20</b> will be an adhesive tape tab. If the outer coversheet <b>16</b> of the absorbent article <b>10</b> is a nonwoven or material layer, a suitable fastening element <b>20</b> will be a hook portion of a hook-and-loop type fastener or an adhesive tape tab. The skilled person will understand suitable combinations of fastening element and outer coversheet which will give the required result. The fastening element <b>20</b> is normally attached to the disposal fastening means <b>18</b> at the end of the disposal fastening means <b>18</b> which is furthest from the attachment point of the disposal fastening means to the outer coversheet <b>16</b>. If the fastening element is an adhesive tape tab, any area with which the adhesive is in contact before use suitably comprises a release-substance, so that the adhesive does not undesirably stick before the disposal fastening means <b>18</b> is deployed.

0045The article has a longitudinal (y) and a transverse direction (x).

0046The disposal fastening means <b>18</b> of the absorbent article <b>10</b> is covered by a material layer <b>22</b> having a surface area such that it extends beyond the disposal fastening means <b>18</b>, said material layer <b>22</b> being attached to or forming an integral part of the outer coversheet <b>16</b> so as to keep the disposal fastening means <b>18</b> hidden when not in use, and that said material layer <b>22</b> is releasable from the outer coversheet <b>16</b> so as to expose the disposal fastening means <b>18</b> for use. A more discrete disposal fastening means <b>18</b> is provided, so that the chances of babies taking an interest in the disposal fastening means are reduced.

0047The disposal fastening means <b>18</b> is thus hidden by the material layer <b>22</b>, which provides a uniform, even surface to the article, and reduces the risk of its undesirable opening or removal before the article is ready for disposal. Desirably, the material layer <b>22</b> has an appearance which is similar to that of the outer coversheet <b>16</b>, so that will be well-concealed against the outer coversheet <b>16</b>. Particularly, the material layer <b>22</b> may comprise nonwoven material, which is the material of choice for the outer coversheet <b>16</b>. In that the disposal fastening means <b>18</b> is hidden under the material layer, it makes it more difficult for infants to remove it. Furthermore, the material layer acts to protect the disposal fastening means <b>18</b> from dirt and damage.

0048So that the disposal fastening means <b>18</b> is not too difficult to locate, it may be desirable for the material layer <b>22</b> to be marked in some way. This may be achieved by introducing a different pattern or colour to its surface from the outer coversheet <b>16</b>. Alternatively, dashed or continuous lines may be used to indicate the location of the disposal fastening means. However, bright, highly-visible markings or colouring which make the material layer <b>22</b> highly attractive to babies should be avoided.

0049The edges of the material layer <b>22</b> which extend beyond the disposal fastening means <b>18</b> are attached to, or form an integral part of the outer coversheet <b>16</b>. This will be described in more detail below.

0050Suitably, the material layer <b>22</b> is provided with perforations, breakable seals or the like for releasing it from the rest of the outer coversheet and thus exposing the disposal fastening means <b>18</b>.

0051The material layer <b>22</b> may be made from any suitable material, although nonwoven materials are particularly of interest. Suitably, the material layer <b>22</b> is of a composition and structure such that it closely resembles the garment-facing surface of the outer coversheet <b>16</b>, especially a nonwoven material or plastic film. In one embodiment, the material layer <b>22</b> can be printed with a pattern <b>36</b>, e.g. text, logotype, numerals, patterns, cartoon characters or other designs so that it blends in with any such pattern <b>36</b> which is printed on the garment facing surface of the outer coversheet <b>16</b> (see <figref idref="DRAWINGS">FIG. 1</figref>).

0052In one embodiment (shown in <figref idref="DRAWINGS">FIG. 2</figref>), the material layer <b>22</b> is a separate piece of material which is joined to the outer coversheet <b>16</b> by a breakable seal <b>28</b>, along at least a portion of the circumference of the material layer <b>22</b>. The breakable seal <b>28</b> may comprise welds, glue, etc. which join the material layer to the outer coversheet <b>16</b>. If the entire circumference of the material layer <b>22</b> is joined to the outer coversheet <b>16</b> by the breakable seal <b>28</b>, the material layer <b>22</b> will be completely removed upon use. Preferably a part of the circumference of the material layer <b>22</b> is not joined to the outer coversheet <b>16</b> so as to leave place for a finger to be inserted under the material layer <b>22</b> and release it from the outer coversheet <b>16</b>.

0053The glue which joins the material layer <b>22</b> to the outer coversheet may comprise capsules of fragrance which break when the seal is broken. A pleasant smell is thereby released which covers any offensive smells emitted from the absorbent article.

0054The disposal fastening means <b>18</b> may be joined to the material layer <b>22</b> by any suitable means. Alternatively, the material layer <b>22</b> is an integral part of the outer surface of the disposal fastening means <b>18</b>. Alternatively, the disposal fastening means <b>18</b> is not joined to the material layer <b>22</b> and functions independently of it.

0055<figref idref="DRAWINGS">FIG. 2</figref> is an enlargement of one embodiment of the disposal fastening means <b>18</b> according to the invention in which the material layer <b>22</b> is attached to the outer coversheet <b>16</b>. The material layer <b>22</b> is thus a separate piece of material which is fastened to the outer coversheet <b>16</b> and held in place by a breakable seal <b>28</b> (e.g. welds or glue sites).

0056<figref idref="DRAWINGS">FIGS. 3</figref><i>a </i>and <b>3</b><i>b </i>are cross-sectional views along the line III-III in <figref idref="DRAWINGS">FIG. 2</figref>. They show the disposal fastening means <b>18</b> according to the invention, hidden under the material layer <b>22</b>. In the embodiment described above, the material layer <b>22</b> is not joined to the outer coversheet <b>16</b> around part of its periphery (in this case the lower edge) so as to leave place for a finger to be inserted under the material layer <b>22</b> and release it from the outer coversheet <b>16</b>. The disposal fastening means <b>18</b> may be of a length such that it must be folded so as to fit under the material layer <b>22</b>. <figref idref="DRAWINGS">FIG. 3</figref><i>a </i>shows the disposal fastening means folded in a Z-fold, although other folding forms are conceivable (e.g. C-fold). Distances between components in this figure have been exaggerated for clarity—in the actual product, the components will lie substantially in contact with one another. The disposal fastening means <b>18</b> may be held in its folded state by means of suitably-arranged glue sites or welds <b>19</b>. In contrast to the glue or welds attaching the disposal fastening means <b>18</b> to the outer coversheet, the glue or welds <b>19</b> holding the folds together will be released when the user or wearer pulls the disposal fastening means <b>18</b> by hand.

0057The glue which holds the disposal fastening means <b>18</b> in its folded state may comprise capsules of fragrance which break when the seal is broken. A pleasant smell is thereby released which covers any offensive smells emitted from the absorbent article.

0058Advantageously, the disposal fastening means <b>18</b> is formed from an elastic material, such that—when not under tension—the disposal fastening means <b>18</b> lies hidden under the material layer <b>22</b> but can be extended under tension.

0059In the embodiment shown in <figref idref="DRAWINGS">FIG. 4</figref> the outer coversheet <b>16</b> of the absorbent article <b>10</b> is a laminate comprising a garment facing layer <b>24</b> and at least one additional layer <b>26</b> located on the inside of the garment facing layer. By “inside” is meant the user-facing side of the outer coversheet <b>16</b>. In this embodiment, the material layer <b>22</b> is an integral part of the garment facing layer <b>24</b> of the outer coversheet <b>16</b>.

0060<figref idref="DRAWINGS">FIGS. 5</figref><i>a </i>and <b>5</b><i>b </i>are cross-sectional views along the line V-V in <figref idref="DRAWINGS">FIG. 4</figref>. As shown in <figref idref="DRAWINGS">FIGS. 5</figref><i>a </i>and <b>5</b><i>b</i>, the disposal fastening means <b>18</b> is located between the garment facing layer <b>24</b> of the laminate and the at least one additional layer <b>26</b>. This embodiment avoids the requirement for a separate material layer <b>22</b>. Again, distances between components in these figures have been exaggerated for clarity—in the actual product, the components will lie substantially in contact with one another.

0061To enable a carer or a user to locate and expose the disposal fastening means <b>18</b> easily, the garment facing layer <b>24</b> of the outer coversheet <b>16</b> may be perforated around at least a part of the circumference of the disposal fastening means <b>18</b>. Removal of the material layer at the perforations <b>28</b> exposes the disposal fastening means <b>18</b> which is then ready for use.

0062Again, in this embodiment, the disposal fastening means <b>18</b> may or may not be joined to the material layer <b>22</b>, as appropriate, provided that its function is not hindered.

0063As mentioned previously, the absorbent article <b>10</b> is preferably a pant-type absorbent article. Such pant-type absorbent articles comprise a front portion <b>30</b>, a crotch portion <b>32</b> and a back portion <b>34</b>, said front and back portions <b>30</b>, <b>34</b> being joined to each other along two opposite longitudinal side edges to define a waist-opening <b>15</b> and a pair of leg-openings <b>17</b>.

0064The disposal fastening means <b>18</b> and associated material layer <b>22</b> may be joined to any portion of the outer coversheet <b>16</b> of the absorbent article. For ease of access, the disposal fastening means <b>18</b> is preferably joined to the front <b>30</b> or back <b>34</b> portion of the absorbent article rather than in the crotch portion.

0065<figref idref="DRAWINGS">FIGS. 6</figref><i>a</i>-<i>c </i>illustrate how the disposal fastening means <b>18</b> according to the invention is employed when disposing of a soiled diaper. Usually, when a pant-type diaper is removed, the side seams are broken. Then, as shown in <figref idref="DRAWINGS">FIG. 6</figref><i>a</i>, the material layer <b>22</b> is removed by tearing perforations or breaking a seal, revealing the disposal fastening means <b>18</b>. The disposal fastening means <b>18</b> is unfolded or stretched out as necessary, as shown in <figref idref="DRAWINGS">FIG. 6</figref><i>b</i>. Finally, the diaper is folded or rolled up into a tight package and the fastening element <b>20</b> of the disposal fastening means <b>18</b> is affixed to the outer coversheet of the diaper, so as to maintain this folded or rolled up state (<figref idref="DRAWINGS">FIG. 6</figref><i>c</i>). Safe, hygienic disposal of the diaper is thus enabled.

0066<figref idref="DRAWINGS">FIG. 7</figref><i>a </i>shows a pant diaper containing the disposal fastening means <b>18</b> according to the present invention in which the disposal fastening means is close to the side seams <b>25</b> of the article and in which it is located between the garment facing layer <b>24</b> of the laminate and the at least one additional layer <b>26</b>. <figref idref="DRAWINGS">FIGS. 7</figref><i>b </i>and <b>7</b><i>c </i>show the construction of such an article.

0067In this case, the garment-facing layer <b>24</b> of the laminate is a nonwoven layer <b>40</b> and the additional layer is a plastic film <b>36</b>. During manufacture, a double Z-folded strip <b>38</b> is attached to a web of the plastic film <b>36</b> in the area which is to become the side seams <b>25</b> such that it overlaps the joint between two adjacent articles on the web of plastic film as shown in <figref idref="DRAWINGS">FIG. 7</figref><i>b</i>. The double Z-folded strip <b>38</b> comprises fastening element <b>20</b> at each end, and may be maintained in its Z-folded form by weak welds or glue sites <b>19</b>.

0068A web of nonwoven material <b>40</b> is affixed on top of the first web of plastic film <b>36</b>. The webs are not attached to each other in the area around the double Z-folded strip <b>38</b>. The second web of material <b>40</b> may comprise perforations <b>28</b> marking the position of the double Z-folded strip <b>38</b>. The double Z-folded strip <b>38</b> is therefore located between the plastic film <b>36</b> and the nonwoven material <b>40</b>. Once joined, the absorbent articles are separated from one another by cutting through both webs and the double Z-folded strip <b>38</b> along the line X-X shown in <figref idref="DRAWINGS">FIG. 7</figref><i>c</i>, which passes through the midpoint of the double Z-folded strip <b>38</b>. The cutting process produces an edge between two articles, each of which incorporates a disposal fastening means <b>18</b> in the area around the side seam <b>25</b>.

0069Extra components such as inner coversheets, absorbent cores, elastic threads or material at the waist or leg openings or leakage barriers for the leg/waist openings may be included in the manufacturing process as required. Waistband material may be joined to each edge of the articles as required. The diapers are folded in half to form a pant-like shape, and the edges containing the disposal fastening means <b>18</b> are bonded to each other to form side-seams.

0070The invention is not limited to the embodiments described above and shown in the drawings, but may be varied within the scope of the claims, and equivalents thereof. In particular, the invention is not limited to a particular type of absorbent article, but the embodiments shown may be applied to any type of absorbent article. Details from the different embodiments may of course be combined as desired, as will be evident to the person skilled in the art.
