DETAILED DESCRIPTION OF PARTICULAR EMBODIMENTS

[0057] Various aspects of the disclosure will now be described more fully hereinafter with reference to the accompanying drawings, in which exemplary embodiments of the disclosure are shown. The exemplary embodiments of the disclosure may, however, be embodied in many different forms and should not be construed as limited to the embodiment set forth herein; rather, these embodiments are provided for thoroughness and completeness. Like reference characters refer to like elements throughout the description.

[0058] For purposes of the description herein the terms rear, front, vertical, horizontal, longitudinal, inner outer, exterior, interior, and derivatives thereof relate to the exemplary embodiment of the disclosure as oriented in, e.g., FIG. 2.

[0059] However, it is to be understood that the exemplary embodiments may assume various alternative orientations, except where expressly specified to the contrary. It is also to be understood that the examples illustrated in the attached drawings, and described in the following specification are simply exemplary embodiments. Hence, dimensions and other physical characteristics relating to the exemplary embodiments disclosed herein are not to be considered as limiting, unless the appended claims expressly state otherwise.

[0060] 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 further relates to a disposable article of the belt type, a so-called belt article or belted article or a conventional open diaper type as further described herein.

[0061] The article comprises generally a chassis part. The article comprises transverse side panels connected to either the front or rear end part of the article's chassis part. The side panels may be an integral part of the chassis or separate parts attached to the chassis.

[0062] FIG. 1 schematically shows some components of a belt type diaper article 10 according to an exemplary embodiment of the disclosure, in which the article 10 is shown from the side which is intended to face towards the wearer when in use.

[0063] FIG. 2 schematically shows some components of an open diaper type article 10 according to an exemplary embodiment of the disclosure, in which the article 10 is shown from the side which is intended to face towards the wearer when in use.

[0064] Further details of the exemplary embodiments of the disclosure are described herein in relation to FIGS. 3A-3B, 4, 5, 6A-C and 7A-C.

[0065] The article 10 comprises a chassis 12 and a side panel 16 and a second side panel 17. Further, the article 10 has a longitudinal direction X and a transverse direction Y. The chassis part 12 comprises a first covering layer 20. In other words, the article has a length extension in the longitudinal direction X and a width extension in the transverse direction Y. Moreover, the chassis 12 has a first end portion 18, a second end portion 14 and a central portion 12 extending therebetween.

[0066] Typically, the article comprises a body-oriented surface 21 facing the user during use and a garment-oriented surface 22 facing away from the user in use.

[0067] In the examples, of FIG. 1-2, the chassis includes the first covering layer 20, which forms the body-oriented surface 21 intended to face towards the user. In addition, the chassis also includes the garment-oriented surface 22 intended to face away from the user in use.

[0068] In other words, there is provided a disposable article 10, which comprises the chassis 12 having first and second end portions 18, 14 and a central portion 12 extending therebetween. The chassis also comprises the first covering layer 20 having the body-oriented surface 21 intended to face towards the user and the garment-oriented surface 22 intended to face away from the user in use.

[0069] In this exemplary embodiment, as shown in FIGS. 1-2, the first end portion is a rear end part 18 and the second end portion is a front end part 14. However, the opposite may also be readily conceivable.

[0070] The article 10 further comprises a pair of side panels 16, 17 attached to the chassis 12 so that the first side panel 16 and the second side panel 17 extend on each side of the first end portion 18 of the chassis.

[0071] In the embodiments of FIGS. 1-2 the side panels 16, 17 are arranged for securing to each other around a waist of a wearer of the article or to a third and fourth side panel respectively. The side panels 16, 17 have an exterior surface 16a, 17a, respectively. Each first and second side panel 16, 17 are connected to the chassis 12 in the rear end part 18, respectively. The first side panel 16 is joined to the longitudinal edge 2 and the second side panel 17 is joined to the opposing longitudinal edge 1.

[0072] Typically, although not strictly required, the side panels may be partly or entirely elastic.

[0073] The first and second side panels 16, 17 here have an inner surface 19 facing the wearer during use and an outer (exterior) surface 16a and 17a facing away from the wearer during use. Thus, the first side panel has an inner surface 19a facing the wearer during use. Likewise, the second side panel has an inner surface 19b facing the wearer during use. In the article shown in FIGS. 1 and 2, the side panels (first side panel 16 and second side panel 17) extend in the transverse direction Y of the article. The side panels (first side panel 16 and second side panel 17) extend also in the longitudinal direction X.

[0074] The first side panel 16 is shown having a fastener 51 or a fastening component adapted to be attached to the second side panel 17 for securing the side panels to each other around the wearer of the article.

[0075] In this example, as shown in, e.g., FIG. 1, the first side panel 16 has a free end 11 which carries the fastener 51 adapted to be attached to an exterior surface 17a of the second side panel 17. The fastener is typically adapted to be attached in a refastenable manner, as is well-known in the art. Further, each one of fastener 51 and a mating fastening component arranged on another side panel to which the fastener 51 is to be attached may comprise a mechanical connector structure being capable of forming a mechanical interconnection with each other. One example of a mechanical connector structure is a hook and loop material. The loop material may be a nonwoven material of the absorbent article, such as a hook-to-textile mechanical connector solution, or the loop material may be a separate loop patch, laminated or attached to the absorbent article. Hereby, the fastener and the mating fastening component are mechanically connectable to form an interconnection between the first side panel and the second side panel for securing to each other around a wearer of the absorbent article. The interconnection may sometimes be referred to as refastenable connection.

[0076] The second end portion 14 of the chassis comprises a fastening device 48, 49 for securing the second end portion 14 of the chassis to the first and second side panels 16, 17 constituting a belt portion in this example so that the article assumes a pant-like shape with the belt portions forming a part of a waist portion of the pant. The second end portion 14 of the chassis is typically secured to the exterior surfaces 16a, 17a of the first side panel 16 and/or second side panel 17.

[0077] In other examples, such as the one shown in FIG. 2, the article 10 is provided with a second pair of side panels attached to the chassis 12 so that the third side panel and the fourth side panel extend on each side of the second end portion 14 of the chassis. The side panels 16, 17 of the first pair of side panels may carry a respective first and second fastener 51 adapted to be attached to the side panels of the second pair of side panels so that the article assumes a pant-like shape when in use.

[0078] Turning now to FIG. 2, the article 10 is depicted in a state in which the first and second side panels 16, 17 are folded over the body-oriented surface 21 to form a folded side panel configuration prior to use of the article 10. Hereby, the first side panel 16 is arranged on top of the second side panel 17. When the article comprises a first covering layer 20, the first and second side panels 16, 17 are folded over the body-oriented surface 21 of the first covering layer 20 to form a folded side panel configuration prior to use of the article.

[0079] Turning again to FIG. 2, the article is here depicted in its folded side panel configuration. As illustrated in FIG. 2, the second side panel 17 is arranged to overlap the chassis of the article, and the first side panel 16 is arranged to overlap the second side panel 17. In other words, the second side panel 17 is arranged to overlap the first end portion 18 of the chassis 12 and the first side panel 16 is arranged to overlap the second side panel 17. In this exemplary embodiment, the second side panel 17 is arranged to overlap an absorption portion of the article and the first side panel 16 is arranged to overlap the second side panel 17 entirely. Thus, when the first side panel 16 and the second side panel 17 are folded over the body-oriented surface 21 to form the folded side panel configuration prior to use of the article, the second side panel 17 is arranged to overlap the absorption portion 40 of the article and the first side panel 16 is arranged to overlap the second side panel 17. To this end, the fastener 51 on the free end 11 of the first side panel is releasably attached to the exterior surface 17a of the second side panel 17.

[0080] Further, the second side panel 17 is releasably bonded to the body-oriented surface 21 of the first covering layer 20 by a first breakable bond 101. In other words, when the first side panel 16 and the second side panel 17 are folded over the body-oriented surface 21 to form the folded side panel configuration prior to use of the article, the second side panel 17 is releasably bonded to the body-oriented surface 21 of the first covering layer 20 by the first breakable bond 101.

[0081] Analogously, the first side panel 16 is releasably bonded to the exterior surface 17a of the second side panel 17 by a second breakable bond 102. In other words, when the first side panel 16 and the second side panel 17 are folded over the body-oriented surface 21 to form the folded side panel configuration prior to use of the article, the first side panel 16 is releasably bonded to the exterior surface 17a of the second side panel 17 by, the second breakable bond 102.

[0082] In the embodiment of FIG. 2, the third and fourth side panels are provided with a respective fastener 48, 49 such as to fasten the third and fourth side panel to the first and second side panel respectively so that the article assumes a pant-like shape when in use.

[0083] In some design variants, any one of the first and second side panels 16, 17 comprises an intermediate elastic region (not illustrated).

[0084] As mentioned above, the article 10 comprises a first covering layer 20, wherein the first covering layer comprises the body-oriented surface 21, intended to face towards the user when the article 10 is used. The article 10 also comprises the opposing garment-oriented surface 22.

[0085] In this example, the first covering layer is a first liquid-permeable covering layer, while a second covering layer is a second substantially liquid-impermeable covering layer 30. The first liquid-permeable covering layer 20 forms the body-oriented surface, whilst the second substantially liquid-impermeable covering layer 22 forms the garment-oriented surface.

[0086] Typically, although not strictly necessary, the first covering layer 20 of the article 10 has an hourglass shape. Other shapes such as a rectangular shape, for example, may also be conceivable in other design variants.

[0087] The first covering layer 20 can consist of any material suitable for the purpose. The most common covering materials for disposable articles are nonwoven textile materials, so-called nonwoven materials manufactured according to various methods. Not so common but also occurring is the use of covering layers 20 of woven material or net material. For example, a nonwoven material suitable as a covering layer 20 can be manufactured from synthetic fibers such as polyester or polypropylene, of natural fibers such as cotton fibers. A mix of synthetic and natural fibers also occurs. The manufacture of a nonwoven material consists of the two main stages of web formation and web bonding. Web formation means that a web is created of as even a surface weight as possible, wherein the web can be created by carding of natural or manmade staple fibers. The spunlaid technique is another web-forming technique, in which polymer material is extruded to thin continuous fiber threads on a continuous conveyor. The extruded thin fiber threads are randomized following extrusion in that they land on the continuous conveyor in a random manner. Web formation can take place in several different ways. A commonly occurring method is so-called thermal bonding, wherein a bonding pattern is melted into the fiber web in a roller nip where at least one of the hot rollers has a pattern. For web formation by means of thermal bonding to work, at least a certain portion of the fibers in the web must consist of synthetic fusible fibers in certain embodiments. Occurring bonding patterns are dots of varying geometry, small rectangular or circular surfaces, floral patterns or the like. What is common to the methods described above, and also to other methods, is that not all the surface of the covering layer 20 is bonded, but between the bonding areas the covering layer has open areas comprising fiber threads that are fixed at one or both of their ends to the adjacent bonded areas.

[0088] Laminate consisting of two or more of the aforementioned possible covering materials may also occur, such as a covering consisting of different materials in different parts of the surface. It also occurs that the covering layer 20 consists of an entirely or partially elastic material to give the article 10 a better fit when in use. The covering layer 20 also has a fastening device (e.g. a first and a second fastening device 48, 49) arranged at the respective longitudinal edge 1, 2 in the front end part 14 of the covering layer 20, i.e. connected to the two front corners of the covering layer 20. The fixing members 48, 49 are arranged on the side of the covering layer 20 that is intended to face towards the user when the article 10 is used. The fastening devices 48, 49 may typically comprise hook elements that are intended, on application of the article 10 to a user, to be connected detachably to loops arranged on the side of the side panels 16, 17 that are intended to face away from the user.

[0089] To improve the fit of the article 10, the longitudinal edges 1, 2 of the first covering layer 20 can be provided with leg elastics 45 arranged substantially in the longitudinal direction X of the article. The task of the leg elastics 45 includes improving the fit of the article, and making the article 10 more like textile multiple-use briefs/pants. Each respective leg elastic 45 can comprise one or more elastic threads that in an extended state have been joined to the covering layer 20 by gluing, ultrasonic welding, or the like. Alternatively, the respective leg elastic 45 can comprise elastic ribbon of foamed material, for example. The respective leg elastic 45 may be arranged on the side of the first covering layer 20 that is intended to face away from the user when in use.

[0090] The rear or front end parts 18, 14 of the article 10 can also be provided with so-called waist elastics 46 in the form of elastic elements arranged along a second transverse edge 5 or a first transverse edge 4 of the article 10 to give the article 10 a soft, flexible enclosure of the user's waist. In FIG. 1, only the front end part 14 of the article 10 is provided with a waist elastic 46. The waist elastic 46 comprises a thin strip of elastic foam material that is attached by glue to the side of the first covering layer 20 that is intended to face away from the user. The waist elastic 46 is applied in a stretched state to achieve a holding-together force that stretches the article 10 around the user's waist.

[0091] According to another aspect of the disclosure, the article 10 comprises a second covering layer 30 arranged on the side of the first covering layer 20 that is intended to face away from the user when in use. The second covering layer 30 has the same extension in the X/Y plane as the first covering layer 20. The second covering layer 30 is typically substantially liquid-impermeable, but other types of covering layers can also exist. The second covering layer 30 can comprise a range of different materials, but most frequently it comprises a thin, preferably liquid-impermeable plastic film, but it is also possible to use other types of substantially liquid-impermeable material such as nonwoven material that has been made substantially liquid-impermeable through plastic coating, for example, a liquid-impermeable foam layer, liquid-impermeable glue or the like. The second covering layer 30 can alternatively comprise a liquid-impermeable vapour-permeable material, a so-called breathable material.

[0092] Furthermore, laminates comprising at least one liquid-impermeable and typically breathable layer arranged against the garment-oriented surface 22 also exist as a second covering layer 30. These laminates usually consist of a liquid-impermeable material acting as a barrier against soaking through and a more textile-like material arranged on the side of the article 10 that is oriented away from the user on use. The outside of the article 10 is thereby more garment-like in use. The textile-like layer of the laminate normally consists of a nonwoven layer, but other textile or textile-like materials also exist. The first covering layer 20 and the second liquid-impermeable covering layer 30 can be joined to one another in several different ways. Examples of joining methods are gluing, thermal fusing, ultrasonic welding or the like. For articles 10 comprising a first covering layer 20 and a substantially liquid-impermeable second covering layer 30, it is suitable for the leg elastic 45 and the waist elastic 46 described above to be arranged between the two covering layers 20, 30. The first covering layer 20 may, in an article 10, have a low absorption capacity wherein smaller bodily secretions such as occasional drops of urine, for example, initially secreted menstruation fluid or similar.

[0093] According to one exemplary embodiment of the disclosure, as shown in FIGS. 1-2, the article 10 has an absorption body 40 arranged between the first covering layer 20 and the second substantially liquid-impermeable covering layer 30. The first covering layer 20 of an article according to this example must be liquid-permeable. The article 10 in accordance with this example relates to a diaper intended to be used by an incontinent adult person or by a child who has not yet become continent. The absorption body 40 has substantially the same profile, but a smaller surface, than the first and second covering layers 20, 30. The two covering layers 20, 30 thus extend outside the edges of the absorption body 40 along the entire circumference of the absorption body 40. The absorption body 40 has, exactly like the covering layers 20, 30, a front and a rear end part and a narrower crotch part located between the end parts. Upon use of an article comprising the absorption body 40, the front part of the crotch part and the front end part principally act like a receiving area for urine, while the rear part of the crotch part and the rear end part act mainly as a receiving area for feces. The liquid-permeable first covering layer 20 and the substantially liquid-impermeable second covering layer 30 are connected to one another outside the absorption body 40 along its entire circumference. The absorption body 40 can be constructed from one or more layers of cellulose fluff pulp. The cellulose fluff pulp can be mixed with fibers or particles of a highly absorbent polymer material, so-called super absorbents, of the type that chemically binds large quantities of fluid on absorption with the formation of a fluid-holding gel. The absorption body 40 can also comprise highly absorbent polymer material arranged in a layer inside the absorption body or connected to the surface or surfaces of the absorption body. The absorption body 40 can further include further components for improving the properties of the absorption body 40. Examples of such components are binding fibers, various types of fluid-dispersing layers or fibers, dimensionally stabilizing components, reinforcing fibers or the like.

[0094] Further, in all exemplary embodiments described herein, and in other possible exemplary embodiments, a part of any one of the first and second side panels extending from the first end portion of the article is typically permanently attached to the first end portion.

[0095] As mentioned above, the article is typically a disposable absorbent article such as a diaper and an incontinence guard. Further, the article 10 in this example comprises the absorption body 40 arranged between the first liquid-permeable covering layer 20 and the second substantially liquid-impermeable covering layer 30.

[0096] FIG. 3A shows another exemplary embodiment of the disclosure, in which the article 10 is depicted in a state in which the first and second side panels 16, 17 are folded over the body-oriented surface 21 to form the folded side panel configuration prior to use of the article 10. Hereby, the first side panel 16 is arranged on top of the second side panel 17. When the article comprises a first covering layer 20, the first and second side panels 16, 17 are folded over the body-oriented surface 21 of the first covering layer 20 to form the folded side panel configuration prior to use of the article. The side panels of FIG. 3A are shorter than the side panels depicted in FIG. 1-2, otherwise the properties of the article are the same. According to FIG. 3A the first breakable bond 101 and the second breakable bond 102 are arranged in the overlap area 100, and overlap each other. In other words; the second breakable bond 102 is arranged on top of the first breakable bond when the article is in the folded side panel state. The first and second breakable bonds 101, 102 are arranged along the longitudinal central line of the article 10, as depicted by the dashed line in FIG. 3A. The breakable bonds 101, 102 are centrally arranged in the longitudinal direction X on the respective side panels 16, 17. In FIG. 3A the breakable bonds are a separate part of the respective side panels 16, 17 and depicted as adhesive spots.

[0097] In FIG. 3B, the first breakable bond 101 forms a pattern over the entire part of the second side panel 17 overlapping the first side panel 16 in the overlap area 100. Similarly, the second breakable bond 102 forms a pattern over the entire part of the first side panel 16 arranged on top of the second side panel 17 in the overlap area 100 when the article is in the folded side panel configuration. In this example, the breakable bond is an integral part of the first and second side panels respectively, and may for example be formed by ultrasonic welding or thermobonding.

[0098] Other embodiments are possible where the breaking bonds are provided with randomly selected or varied patterns.

[0099] The breakable bonds are typically centrally arranged in the longitudinal direction X of the of the side panel. However, variants are conceivable wherein any desired asymmetry of the arrangement of the breakable bonds is possible.

[0100] In view of the above disclosure explaining how to provide the breakable bonds on the side panels, it will be understood that the article is provided with improved ability in terms of allowing a user of the article to release the side panels and unfold the side panels from their folded configuration in a simple motion.

[0101] FIG. 4 shows another exemplary embodiment of the disclosure, in which at least one of the side panels is folded in order to wrap up a length of the at least one side panel. As mentioned above, the article 10 has a body-oriented surface 21 facing the user during use and a garment-oriented surface 22 facing away from the user in use. The article further comprises a pair of side panels 16, 17 attached to the chassis so that a first side panel 16 and a second side panel 17 extend on each side of the first end portion 18 of the chassis. In this example, the folded side panel configuration is formed by having the second side panel 17 folded over the body-oriented surface 21, although the second side panel is illustrated in FIG. 4 in an unfolded position (or loose hanging position).

[0102] In addition, as is clearly shown in FIG. 4, the first side panel 16 is folded in order to wrap up a length of the side panel 16. Typically, although not strictly required (and not shown), the second side panel 17 is also folded in order to wrap up a length of the side panel 17. In this exemplary embodiment, the first belt portion is folded, over the body-oriented surface 21 in an accordion-like fashion to form a Z-shape, as seen in a cross section taken along the transverse direction Y. The accordion-like fold may however also be formed in several different manners, for example being folded in a Z-shape, M-shape, W-shape or the like, over the body-oriented surface. In this example, the extension of the folded side panel is less than half the transverse length of the chassis, as shown in FIG. 4. However, the extension of the folded side panel may be varied depending on type of article, type of side panel, type of fold and/or desired length of the side panel when being unfolded. It is appreciated that an even larger amount of folds can be used in order to fold a desired amount of material of a side panel, in particular a belt side panel. For instance, a first fold may be a hook protection fold, wherein a portion of the backsheet nonwoven side panel is folded over, thereby at least partly covering and protecting the hooks when the absorbent article is in a state prior to being worn by a user, such as when provided in a product package during shipping (not shown). The hook protection fold keep the hooks from attaching to other parts of the absorbent article during manufacturing, packaging or transport.

[0103] FIGS. 6A-C illustrate further exemplary embodiments of the breakable bond arrangements in the folded side panel configuration prior to use of the article 10. The article is in the folded side panel configuration in FIGS. 6A-C. The distal edge 103 of the first side panel 16 is preferably free such that it is grippable by a user intending to release the breakable bonds to unfold the folded side panel configuration.

[0104] In FIG. 6A the first breakable bond 101 is arranged adjacent the distal edge 104 of the second side panel 17. The second breakable bond 102 is arranged adjacent the distal edge 103 of the first side panel 16.

[0105] In FIG. 6B the second breakable bond 102 is arranged along the longitudinal central line of the end portion of the chassis 12 of the article. 10. The first breakable bond 101 is arranged adjacent the fold line of the second side panel 17, and is not arranged in the overlap area 100.

[0106] The first side panel 16 depicted in FIG. 6C is longer than the second side panel 17. The first breakable bond 101 is arranged centrally in transverse direction Y of the chassis 12. The second breakable bond 102 is arranged to cover several parts of the part of the first side panel 16 arranged on top of, and thereby overlapping, the second side panel 17.

[0107] In one design option, although not illustrated, the second side panel 17 can likewise be folded over the garment-oriented surface 22 (when the side panels 16, 17 are in the folded side panel configuration prior to use).

[0108] FIGS. 7A-C illustrate the sequential release of the breakable bonds 101, 102 once the first side panel 16 is being pulled, preferably by its free distal edge 103. The first breakable bond 101 between the second side panel 17 and the chassis 12 is weaker in peel strength than the second breakable bond 102 between the second side panel 17 and the first side panel 16 arranged in top of the second side panel 17. Due to the weaker bond strength, the first breakable bond will break first, thereby releasing the bonded second and first side panels 16, 17 from the chassis 12. The second breakable bond 102 is still intact in FIGS. 7A-B. Continuous pulling of the first side panel will, eventually also release the second breakable bond 102, and thereby provide two loose side panels 16, 17 as illustrated in FIG. 7C. In one single grip, and by one single pulling motion, both the side panels 16, 17 can be sequentially released; thereby facilitating the unwrapping of the article from a folded side panel configuration to a ready-to-use configuration. The side panels 16, 17 in FIG. 7C are readily available for use.

[0109] As mentioned above, in all exemplary embodiments described herein, and in other possible exemplary embodiments, a part of any one of the first and second side panels extending from the first end portion of the article is typically permanently attached to the first end portion. In other words, an end portion 26 of the first side panel 16 is here permanently attached to the first end portion 18 of the chassis. Analogously, an end portion 27 of the second side panel 17 is here permanently attached to the first end portion 18 of the chassis. Also, as mentioned above, the article is typically a disposable absorbent article such as a diaper and an incontinence guard. Further, the article 10 in the exemplary embodiments described above comprises the absorption body 40 arranged between the first liquid-permeable covering layer 20 and the second substantially liquid-impermeable covering layer 30.

[0110] The term nonwoven is applied to a wide range of products which in term of their properties are located between the groups of paper and cardboard on the one hand and textiles on the other hand. As regards nonwovens, a large number of extremely varied production processes are used, such as airlaid, wetlaid, spunlaced, spunbond, meltblown techniques etc. The fibers may be in the form of endless fiber or fibers prefabricated with an endless length, as synthetic fibers produced in situ or in the form of staple fibers. Alternatively, they may be made from natural fibers or from blends of synthetic fibers and natural fibers.

[0111] By absorbent article is meant an article that absorbs or is adapted to absorb bodily fluids, such as urine and/or blood.

[0112] The disclosure also covers all conceivable combinations of the described aspects, variants, alternatives and exemplary embodiments of the disclosure.

[0113] Furthermore, the disclosure is not limited to the aforesaid aspects or examples, but is naturally applicable to other aspects and exemplary embodiments within the scope of the following claims.

[0114] Reference signs mentioned in the claims should not be seen as limiting the extent of the matter protected by the claims, and their sole function is to make claims easier to understand.

DESCRIPTION OF TEST METHOD

[0115] Measuring the strength of the first and second bonds, the peel strength of the bonds, may be done using a conventional tensile tester (available e.g. from Instron, 825 University Avenue, Norwood, Mass. 02062 USA or Lloyd corporations).

[0116] The width of the upper and lower clamps of the tensile tester should be wide enough so that they can grab and clamp over the whole width of the side panels thereby ensuring that an even tensile force is applied to the side panels.

[0117] The whole waist part of the diaper should be cut off, to a width corresponding to the width of the side panels, when the side panels are of essentially the same width. Thereafter, first measure the strength of the second breakable bond (i.e. the panel to panel bond) of the disposable article.

[0118] Insert the distal end of the first side panel into the upper (movable) clamp, and insert the chassis section of the disposable article, the longitudinal edge of the chassis arranged adjacent the distal end of the first side panel and which longitudinal edge to which the second side panel is fixedly attached to, into the bottom (fixed) clamp. The gauge length (the distance between the clamps) can suitably be 25 mm or less, prior to operating the tensile tester for measuring the strength of a bond.

[0119] When starting the test, the upper clamp should be raised with a crosshead speed of 500 mm/min. Gently hold or support the sample (the not yet separated section) at a 90 angle (i.e. perpendicular to the vertical line between the clamps) during the test. End the test when all bonds, or in the case of a single bond between the side panelsthe second breakable bond, between the first side panel and the second side panelhave been completely separated.

[0120] Next measure the first breakable bond (i.e. panel to chassis) using the same procedure, as when measuring the second breakable bond(s). Insert the distal end of the second side panel into the upper (movable) clamp, and insert the chassis section, the longitudinal edge of the chassis arranged adjacent the distal end of the second side panel and which longitudinal edge to which the first side panel is fixedly attached to of the disposable article, into the bottom (fixed) clamp. Gently hold or support the sample (the not yet separated section) at a 90 angle (i.e. perpendicular to the vertical line between the clamps) during the test, when the gauge length (the distance between the clamps) is increased. End the test when all bonds, or in the case of a single bond between the second side panel and the chassisthe first breakable bond, between the second side panel and the chassishave been completely separated.

[0121] The peel strength equals the maximum value in Newtons (N), measured during testing using the tensile tester, for the respective panel to panel and panel to chassis separations. The reported value should be an average from at least five different diapers.

[0122] The testing method is applicable to embodiments comprising: a single first and/or breakable bond, as well as a plurality of first and/or second breakable bonds.
