Belted absorbent article TECHNICAL FIELD
This disclosure relates to a belted absorbent article comprising a chassis and a pair of belt portions forming a belt around a waist of a wearer. The belted absorbent article may be provided in various sizes.
Absorbent articles in the form of disposable diapers are generally known in which the diaper is provided with a fastening system including a pair of fastening tabs secured to both sides of one end region of the diaper. The fastening tabs are intended to engage receiving means located on the other end region of the diaper. Such a diaper is generally placed on the wearer when the wearer is lying down. While the above-described fastening arrangement is satisfactory when applying diapers to a young child or baby, problems can arise when trying to fit an incontinence diaper to an adult wearer. This is particularly true for wearers who wish to apply the diaper to themselves, or for caregivers who receive a significant benefit from applying the diaper when the wearer is in a standing position. To address this issue, a belted absorbent article has been developed, which allows a wearer or caregiver to apply the diaper in a standing position. A belted absorbent article typically has a belt attached integrally with the chassis or the absorbent article. The belt may have two belt portions extending on either side of the rear end of the chassis or the absorbent section. The two belt portions are intended to be fastened around the waist of the wearer, whilst the front end of the absorbent section hangs down between the legs of the wearer. Once the belt portions have been joined together, the wearer can reach between his or her legs to draw up the absorbent section between the legs and to attach the free end of the absorbent section to the belt portion. Similarly, the article can be made so that the belt is fastened to the front portion of the article and is secured around the back of the wearer. In this case, the absorption section will be hanging down in the front and will be secured to the belt in the back. This type of article is particularly useful for caregivers who care for patients that may have dementia or the like.
For persons having weaker eyesight, it may be appropriate to provide each belt portion with means for identification and distinction of the different ends of the belt portions from each other. As an example, US 2002/032425 A1 discloses an absorbent article comprising a pair of belt portions attached to the rear portion, alternatively the front portion of the article, in which the belt portions are provided with at least one means for identification and distinction of the different ends of the belt portions from each other. By distinguishing the different ends of the belt portions from each other, it is believed that the wearer is guided on how to apply the article as soon as the article is unfolded from its folded state and the belt portions are unfolded, i.e. hanging loose from the rear portion.
However, despite the activity in the field, exemplified by the above-cited disclosure, there remains a need for an improved belted absorbent article.
It is desirable to provide an improved belted disposable article, in which the belted portions are easy and quick to open up already when the belts are in a folded configuration.
An aspect of the present invention provides a belted disposable article comprising a chassis having first and second end portions and a central portion extending therebetween, said article having a body-oriented surface facing the user during use and a garment-oriented surface facing away from the user in use, said article further comprising a pair of belt portions attached to the chassis so that a first belt portion and a second belt portion extending on each side of the first end portion of the chassis for securing to each other around a waist of a wearer of the article to form a belt having an exterior surface, wherein any one of the belt portions carries a fastener adapted to be attached to an exterior surface of the other of the belt portions, and wherein said second end portion of the chassis comprises a fastening device for securing the second end portion of the chassis to one of the belt portions so that said article assumes a pant-like shape with the belt portions forming a part of a waist portion of the pant, wherein a beltopening trigger zone is disposed adjacent a free end of at least one of said first and second belt portions, and said first and second belt portions being folded over said chassis to form a folded belt configuration prior to use of said article, so that said beltopening trigger zone is visible by a user when said belt portions are in said folded belt configuration, and wherein said belt-opening trigger zone of the at least one belt portion resembles the shape of an arrow defining a pointer directing a user to the free end of the at least one belt portion when said belt portions are in said folded belt configuration.
In this manner, a wearer or caregiver is not only guided to identify the free end of a belt portion (e.g. the first belt portion) when the belt portions are in the folded belt configuration, but also triggered to open up the belt portions, i.e. at least unfold one of the folded belt portions having the visible belt-opening trigger zone, prior to place the belt (belt portions) and the article around the waist of the wearer. In other words, the beltopening trigger zone is adapted to identify the free end of the at least one belt portion having the belt-opening trigger zone when the belt portions are in the folded belt configuration and to trigger a wearer or caregiver to initially unfold the belt portions into an unfolded belt configuration. In this context, the unfolded belt configuration refers to a configuration in which each one of the belt portions are unfolded from a surface of the chassis such as the body-oriented surface or the garment-oriented surface. A beltopening trigger zone arranged adjacent the free end of the at least one belt portion is also useful to distinguish the free end of the at least one belt portion from the other end of the at least one belt portion, which is normally permanently attached to the chassis. In many types of belted articles, the free end and the other permanently attached end of the belt portion are essentially considered identical when being arranged in the folded belt configuration. Thus, by the provision of having the belt-opening trigger zone disposed adjacent the free end of the at least one belt portion, it becomes possible to reduce the risk of having a wearer or caregiver trying to open up the belt portion at the wrong end, i.e. the permanently attached end. To this end, the example embodiments of the disclosure provides the advantage that less considerations is needed to find the free end of the belt portion already when the article is in the folded belt configuration.
Accordingly, the example embodiments enables a user to easier identify the free end portion of the belt when the belt portions are in the folded belt configuration prior to use of the article, while reducing the risk of having the user to damage the article when folding up the belt portions of the article prior to use of the article. Hence, it becomes easier for the user or caregiver to understand how to open the folded belt portions from the folded belt configuration. Depending on the type of folded belt configuration of the article prior to use, the belt-opening trigger zone also contributes to easier identify the at least one belt portion when the belt portion has been folded over a surface resembling the belt portions and/or to easier identify the at least one belt portion when the belt portion has been folded over a surface of the same belt portion, another belt portion or any one of the body-facing and the garment-facing surfaces.
In addition, the belt-opening trigger zone may contribute to further enhance the act of identifying one end portion of the belt when the belt portions are in a ready-to-use position or in a user position.
When the belt portions are in the folded belt configuration prior to use, at least the first belt portion is typically, although not strictly required, releasably attached to a part of any one of the body-oriented surface, the garment-oriented surface, the first belt portion and the second belt portion. Thus, in some example embodiments, the first belt portion and the second belt portion are fastened or secured or pegged together with at least one releasable attachment in the overlap when said belt portions are in the folded belt configuration. This releasable attachment in the overlap of the free end portions ensures that the free end portions of the belt portions do not move around before they are unfolded. Any potentially dangling loose ends of the free end portions of the belt portions are typically appropriately fastened such that the free ends are confined to one specific location or area within the boundaries of chassis of the article.
The term "releasably attached” or “releasably attachment” as it is used herein indicates a bond between two surfaces or parts, or a combination thereof that, on the one hand, can be easily broken by a user by simply pulling apart one belt from the other but, on the other hand, is strong enough to withstand any forces acting on the belts during the manufacturing process. Such a bond can be formed by a breakable bond, for example, by a breakable adhesive, spot welding, thermobonding, compression bonding, ultra-sonic welding or the like, and typically leads to a bond that cannot be re-fastened once it has been broken.
Accordingly, the releasable attachment of the belt portion to another surface or another portion may be provided in several different manners as well as in several different configurations. The spatial confinement of the first and second belt portions can be further improved by also attaching at least one of the free end portions to the chassis by at least a releasable attachment.
In other words, at least the first belt portion may be releasably attached to a part of the body-oriented surface. In addition, or alternatively, at least the first belt portion may be releasably attached to a part of the garment-oriented surface. In addition, or alternatively, at least a part of the first belt portion may be releasably attached to another part of the first belt portion. In addition, or alternatively, at least the first belt portion may be releasably attached to a part of the second belt portion.
Analogously, the second belt portion may be releasably attached to a part of the body-oriented surface. In addition, or alternatively, the second belt portion may be releasably attached to a part of the garment-oriented surface. In addition, or alternatively, the second belt portion may be releasably attached to a part of the first belt portion. In addition, or alternatively, a part of the second belt portion may be releasably attached to another part of the second belt portion.
In one design variant, the second belt portion is releasably attached to the body-oriented surface by a breakable bond.
In one design variant, the first belt portion is releasably attached to the exterior surface of the second belt portion by a breakable bond.
As mentioned above, the term “folded belt configuration” of the first and second belt portions refers to an orientation of the belt portions prior to use of the article. Typically, although not strictly required, the folded belt configuration of the belt portions is formed during manufacturing and assembling of the article. The belt portions of the article can be folded in several different manners in order to form the folded belt configuration.
Typically, the folded belt configuration may be formed by the at least one belt portion being folded over the body-oriented surface or over the garment-oriented surface. In other words, when the belt portions are in the folded belt configuration prior to use, the at least one belt portion is folded over the body-oriented surface or over the garment-oriented surface. Analogously, when the belt portions are in the folded belt configuration prior to use, the other one of the belt portions is also folded over the body-oriented surface or over the garment-oriented surface.
As an example, the folded belt configuration can be formed by the first belt portion being folded over the body-oriented surface or over the garment-oriented surface. In other words, when said belt portions are in the folded belt configuration prior to use, at least the first belt portion is folded over the body-oriented surface. In one design variant, when said belt portions are in the folded belt configuration prior to use, at least the first belt portion is folded over the garment-oriented surface.
In some example embodiments, the at least one of said first and second belt portions having the belt-opening trigger zone is folded in order to wrap up a length of the at least one belt portion. Typically, the at least one belt portion is folded in an accordion-like fashion in order to wrap up a length of said belt portion. The accordionlike fold can 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 or over the garment-oriented surface. Typically, accordion folds refer to zig-zag folds with at least two parallel folds that go in opposite directions. Although the length of each folded panel may be about the same size, it should be readily appreciated that the term accordion fold also includes variants in which the folded panels are of different sizes, a higher number of parallel folds, and/or a combination thereof. Further, the folded panels making up the accordion fold may be held together by a releasable attachment, as mentioned above. By the above wrap up configuration of a belt portion, it becomes possible to accommodate longer belt lengths. Folding the belt portions ensures that even longer belt portions can be confined within the boundaries of the chassis surface. In this context, it may be particularly advantageous to fold the belt portion in a Z- shape such that the front end of the free end portion is situated in the direction of the longitudinal extension of the belt portion such that a user can easily grasp the free end portion. This arrangement is also more intuitive for a user since the free end portion of the belt extends in the direction in which the user expects it to unfold.
In one example embodiment, the longitudinal extension of the belt portion is equal to, or is longer than the maximum lateral extension of the chassis. The arrangement of the belt portion as described above is particularly advantageous with reasonably long belts, in particular belt portions of the length being equal to, or longer, than the maximum lateral extension of the chassis because any clogging or jamming of the production and/or packaging lines can be prevented. Longer belts can be more comfortable to wear for a wearer under certain circumstances.
In order to further improve the handling of the belt portions of the absorbent article and of the absorbent article itself during manufacture and during packaging, the first and second belt portions may overlap in the regions of the free end portions when the belt portions are in the folded belt configuration. This overlap of the free end portions of the first and second belt portion provides an improved handling since a greater length of the belt can be positioned inside the boundaries of the body-oriented surface or the garment-oriented surface.
Accordingly, in some example embodiments, the first belt portion at least partly overlaps the second belt portion. In one example, the first belt portion entirely overlaps the second belt portion. As such, when the belt portions are in the folded belt configuration prior to use, the first belt portion at least partly or entirely overlaps the second belt portion.
The first and second belt portions may also be folded in other ways when forming the folded belt configuration prior to use of the article. For instance, each one of the first belt portion and the second belt portion may be double folded. Alternatively, the second belt portion may be double folded over the chassis, whilst the first belt portion is folded over the second belt portion. It may even be conceivable that the first belt portion is double folded over the chassis, whilst the second belt portion is folded over the second belt portion.
The belt-opening trigger zone (of the at least one belt portion) resembles the shape of an arrow defining a pointer directing a user to the free end of the at least one belt portion when the belt portions are in the folded belt configuration. In this manner, the risk of having a wearer or caregiver trying to open up the belt portion at the wrong end is even further reduced.
The belt-opening trigger zone can be disposed on the belt portion(s) in several different ways. As an example, the belt-opening trigger zone is a printed belt-opening trigger zone. Alternatively, the belt-opening trigger zone is an embossed belt-opening trigger zone. In yet another example, the belt-opening trigger zone is a combined printed and embossed belt-opening trigger zone.
In addition, or alternatively, the said belt-opening trigger zone is a label attached to a surface of the first belt portion. A combination of a label and printed and/or embossed belt-opening trigger zone is also conceivable.
According to one example embodiment, a remaining belt section of the at least one belt portion has an essentially uniform non-patterned exterior surface.
By way of example, the remaining belt section of the at least one belt portion is free from distinguishable indicators.
In some example embodiments, any one of the first and second belt portions comprises a corresponding intermediate elastic region.
According to some design variants, the belt-opening trigger zone comprises a tactile region having a tactile characteristic different than the other parts of the at least one belt portion. A tactile region having a tactile characteristic different than e.g. the other parts of the first belt portion can be provided e.g. by using a different material of belt opening trigger zone than the other parts of the first belt portion. In addition, or alternatively, a tactile region having a tactile characteristic different than the other parts of the first belt portion can be provided by treating the material or surface of the beltopening trigger zone, e.g. by coating, embossing or the like.
In addition, or alternatively, the belt-opening trigger zone may comprise a visual region having a colour characteristic different than the other parts of the at least one belt portion.
In some design variants, the belt-opening trigger zone comprises a plurality of belt-opening trigger zone elements. As an example, each one of belt-opening trigger zone elements are provided in the form of an arrow defining a pointer directed towards the free end of the at least one belt portion. Further, each one of belt-opening trigger zone elements may typically be arranged to form a pattern over a surface of the at least one belt portion. With “a pattern” is meant herein an organised arrangement of at least one belt-opening trigger zone element. Such a pattern may be formed by various types of belt-opening trigger zone elements.
The belt-opening trigger zone may have a length in the transversal direction of the belt of about 5-40 mm, preferably a length in said direction of about 10-35 mm, still preferably a length in said direction of about 20-30 mm.
The belt-opening trigger zone may have a length in the longitudinal direction of the belt of about 10-100 mm, preferably a length in said direction of about 15-50 mm, still preferably a length in said direction of about 25-40 mm.
Typically, the belt-opening trigger zone is arranged on the exterior surface of the at least one belt portion. Hence, the belt-opening trigger zone is arranged on the exterior surface of the first belt portion. Alternatively, or in addition, the belt-opening trigger zone is arranged on the exterior surface of the second belt portion.
According to one example embodiment, a second belt-opening trigger zone is disposed adjacent a free end of the other one of the belt portions.
According to one example embodiment, a second belt-opening trigger zone is disposed of the second belt portion and arranged adjacent a free end of the second belt portion. The second belt-opening trigger zone may incorporate any one of the examples, features, functions and/or arrangements as described in relation to the beltopening trigger zone above besides that the second belt-opening trigger zone is arranged on the other belt portion, typically corresponding to the second belt portion instead of the first belt portion.
Typically, although not strictly necessary, the second belt portion is arranged to overlap an absorption portion of the article and the first belt portion is arranged to overlap the second belt portion. Thus, when the first and second belt portions being folded over the body-oriented surface to form the folded belt configuration prior to use of the article, the second belt portion is arranged to overlap an absorption portion of the article and the first belt portion is arranged to overlap the second belt portion so that a fastener on the free end of the first belt portion is refastenable attached to the exterior surface of the second belt portion.
In one example embodiment, the second belt portion is releasably attached to the body-oriented surface by a breakable bond. Thus, when the first and second belt portions being folded over the body-oriented surface to form the folded belt configuration prior to use of the article, the second belt portion is releasably attached to the body-oriented surface by a breakable bond.
Analogously, the first belt portion is releasably attached to the exterior surface of the second belt portion by a breakable bond. Thus, when the first and second belt portions being folded over the body-oriented surface to form the folded belt configuration prior to use of the article, the first belt portion is releasably attached to the exterior surface of the second belt portion by a breakable bond.
In some design variants, a part of the free end adjacent a free end edge is distinguished from the remaining parts of the article by colour, pattern or the like.
Typically, although not strictly necessary, a part of any one of the first and second belt portions, which extends from the first end portion of the article, is permanently attached to the first end portion.
In some example embodiments, the belted article is a disposable absorbent article such as a diaper and an incontinence guard.
In some example embodiments, the belted article has an absorption body arranged between a first liquid-permeable covering layer and a second substantially liquid-impermeable covering layer. Typically, the first liquid-permeable covering layer forms the body-oriented surface, whilst the second substantially liquid-impermeable covering layer forms the garment-oriented surface.

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 example 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 character refer to like elements throughout the description.
For purposes of description herein the terms "rear," "front," "vertical," "horizontal,", “longitudinal,”, "inner," "outer,", “exterior,”, “interior”, and derivatives thereof relate to the example embodiment of the disclosure as oriented in e.g. fig. 2. However, it is to be understood that the example 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 example embodiments disclosed herein are not to be considered as limiting, unless the appended claims expressly state otherwise.
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. Thus, hereinafter, the belted disposable absorbent article may be referred to as the belted absorbent article, the belted disposable article, the belted article, the belt article or simply as the article.
The article comprises generally a belt and a chassis part. Belted articles comprise a transverse belt connected to either the front or rear end part of the article's chassis part. When applying such a belt article, the belt is fixed in a first stage around the user's waist. The chassis part of the belt article is hanging loosely from the belt in this type of article. The chassis part is then led between the user's legs and attached to the belt, wherein the belt comprises fixing surfaces intended to stick fast to a fixing member or fastening device arranged on the chassis part by its free transverse edge.
Figures 1 and 2 schematically show some components of a belted article 10 according to an example embodiment of the disclosure, in which the belted article 10 is shown from the side which is intended to face towards the wearer when in use. Further details of the example embodiments of the disclosure are described herein in relation to figs. 3a-3c, 4, 5 and 6.
The belted article 10 comprises a chassis and a waist belt 15. The belt in this example embodiment includes a first belt portion 16 and a second belt portion 17. Further, the belted 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 belted 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 12a extending therebetween.
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.
In this example, 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.
In other words, there is provided a belted disposable article 10, which comprises the chassis 12 having first and second end portions 18, 14 and a central portion 12a 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.
In this example embodiment, as shown in figs. 1 and 2, the first end portion is a rear end part 18 and the second end portion is a front end part 14.
The article further comprises a pair of belt portions 16, 17 attached to the chassis 12 so that the first belt portion 16 and the second belt portion 17 extend on each side of the first end portion 18 of the chassis for securing to each other around a waist of a wearer of the article to form the belt having an exterior surface 16a, 17a. Thus, each first and second belt portions 16, 17 are connected to the chassis 12 in the rear end part 18, respectively. The first belt portion 16 is joined to the longitudinal edge 2 and the second belt portion 17 is joined to the opposing longitudinal edge 1.
Typically, although not strictly required, the belt portions may be partly or entirely elastic. Thus, hereinafter, the waist belt may sometimes also be referred to as the waist elastic belt, the elastic belt or simply as the belt. The belt 15 of the belted article 10 is intended to encircle a user's waist. In other words, the belt portions 16, 17 forming the belt are intended to encircle a user’s waist. The belt here has an inner surface 19 facing the wearer during use and an outer (exterior) surface 16a and 17a facing away from the wearer during use, wherein said belt comprises the first belt portion 16 and the second belt portion 17. Thus, the first belt portion has an inner surface 19a facing the wearer during use. Likewise, the second belt portion has an inner surface 19b facing the wearer during use. In the belt article shown in figs. 1 and 2, the belt portions (first belt portion 16 and second belt portion 17) extend in the transverse direction Y of the belt article. The belt portions (first belt portion 16 and second belt portion 17) extend also in the longitudinal direction X.
The first belt portion 16 and the second belt portion 17 are attached to the chassis 12 so that said first belt portion 16 and said second belt portion 17 each extends on each side of the first end portion of the chassis for securing to each other around a wearer of the article. To this end, as will be further described hereinafter, the first belt portion 16 has a fastener (51) or a fastening component adapted to be attached to second belt portion 17 for securing the belt portions to each other around the wearer of the article.
In this example, as shown in e.g. figs. 1-3a, the first belt portion has a free end 11 which carries the fastener 51 adapted to be attached to an exterior surface 17a of the other of the belt portions, i.e. the second belt portion 17. In this example, the fastener is configured to be refastenable attached to the surface 17a. Accordingly, the fastener is a so called refastenable fastener configured to be refasten to another part of the article to form an interconnection between the mating componentns. Hence, the fastener is typically adapted to be attached in a refastenable manner, as is well-known in the art. The exterior surface 17a of the other of the belt portions may in some examples be provided with a mating fastening component (not shown). Further, each one of fastener 51 and the mating fastening component 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. Hereby, the fastener and the mating fastening component are mechanically connectable to form an interconnection between said first belt portion and said second belt portion for securing to each other around a wearer of the absorbent article. The interconnection may sometimes be referred to as refastenable connection.
As mentioned above, 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 belt portion 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 belt portion 16 and/or second belt portion 17.
In other words, the front end part, i.e. second end portion 14 of the chassis includes the fastening device(s) 48, 49 for securing the front end part of the chassis to the belt.
Turning now to fig. 2, the article is depicted in a state in which the first and second belt portions 16, 17 are folded over the body-oriented surface 21 to form a folded belt configuration prior to use of the article. Hereby, the first belt portion 16 is arranged on top of the second belt portion 17. When the article comprises a first covering layer 20, the first and second belt portions 16, 17 are folded over the body-oriented surface 21 of the first covering layer 20 to form a folded belt configuration prior to use of the article. Further, fig. 2 illustrates a belt-opening trigger zone 50 being disposed on the first belt portion and arranged adjacent a free end 11 of the first belt portion 16. In other words, the belt-opening trigger zone 50 is disposed adjacent the free end 11 of the first belt portion 16. Various examples of the belt-opening trigger zone 50 will be described further in particular with respect to fig. 3a-3c hereinafter. It should be readily appreciated that the features, functions, examples and details of the belt-opening trigger zone 50 as described in relation to the figs. 3a-3c may be incorporated into an article as described in conjunction with figs. 1 and 2 and/or the example embodiments described in conjunction with figs 4-6 hereinafter.
Turning now again to fig. 2, the belted article is here depicted in its folded belt configuration. As illustrated in fig. 2, the second belt portion 17 is arranged to overlap the chassis of the article and the first belt portion 16 is arranged to overlap the second belt portion. In other words, the second belt portion 17 is arranged to overlap the first end portion 18 of the chassis 12 and the first belt portion 16 is arranged to overlap the second belt portion 17. In this example embodiment, the second belt portion 17 is arranged to overlap an absorption portion of the article and the first belt portion 16 is arranged to overlap the second belt portion 17. Thus, when the first belt portion 16 and the second belt portion 17 are folded over the body-oriented surface 21 to form the folded belt configuration prior to use of the article, the second belt portion 17 is arranged to overlap the absorption portion 40 of the article and the first belt portion 16 is arranged to overlap the second belt portion 17. To this end, the fastener 51 on the free end 11 of the first belt portion is releasably attached to the exterior surface 17a (see e.g. fig. 3a) of the second belt portion 17.
Further, the second belt portion 17 is releasably attached to the body-oriented surface 21 of the first covering layer 20 by a breakable bond. In other words, when the first belt portion 16 and the second belt portion 17 are folded over the body-oriented surface 21 to form the folded belt configuration prior to use of the article, the second belt portion 17 is releasably attached to the body-oriented surface 21 of the first covering layer 20 by a breakable bond.
Analogously, the first belt portion 16 is releasably attached to the exterior surface 17a of the second belt portion 17 by a breakable bond. In other words, when the first belt portion 16 and the second belt portion 17 are folded over the body-oriented surface 21 to form the folded belt configuration prior to use of the article, the first belt portion 16 is releasably attached to the exterior surface 17a of the second belt portion 17 by a breakable bond.
It is to be noted that the term belt portion, belt half, or belt end section, does not mean that the two belt portions, belt halves, or belt end sections, must be of the same length. In alternative embodiments, one belt portion can be longer than the other. It is important, however, that the combined length of the two belt portions reaches around a user's waist. In an alternative aspect of the disclosure, the two belt portions 16, 17 of the belted article 10 can consist of only one piece of material, which piece of material extends in the transverse direction Y across the entire rear end part 18 and past the respective longitudinal edges 1, 2. The belt 15 can, in accordance with other alternative aspects of the disclosure, be inelastic or partly elastic. A partly elastic belt means that certain parts of the length of the belt have elastic properties, while certain other parts of the length of the belt do not have elastic properties.
In some design variants, any one of the first and second belt portions 16, 17 comprises an intermediate elastic region (not illustrated).
As mentioned above, the belt article 10 here 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 belt article 10 is used. The belt article 10 here also comprises the opposing garment-oriented surface 22.
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 forms the body-oriented surface, whilst the second substantially liquid-impermeable covering layer forms the garment-oriented surface.
Typically, although not strictly necessary, the first covering layer 20 of the belt article 10 has an hourglass shape. Other shapes such as a rectangular shape, for example, may also be conceivable in other design variants.
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 fibres such as polyester or polypropylene, of natural fibres such as cotton fibres. A mix of synthetic and natural fibres also occurs. The manufacture of a nonwoven material consists of the two main stages 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 fibres. The spunlaid technique is another web-forming technique, in which polymer material is extruded to thin continuous fibre threads on a continuous conveyor. The extruded thin fibre threads are randomised 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 fibre 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 fibres in the web must consist of synthetic fusible fibres. 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 fibre threads that are fixed at one or both of their ends to the adjacent bonded areas.
Laminate consisting of two or more of the aforementioned possible covering materials 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 belt 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 devices 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 belt article 10 is used. The fastening device 48, 49 may typically comprise hook elements that are intended, on application of the belt article 10 to a user, to be connected detachably to loops arranged on the side of the belt 15 that is intended to face away from the user.
In other words, said second end portion 14 of the chassis typically includes a fastening device 48, 49 for securing the second end portion 14 of the chassis to the waist belt 15. Typically, the second end portion 14 of the chassis typically includes a fastening device 48, 49 for securing the second end portion 14 of the chassis to the first belt portion 16 and/or second belt portion 17.
In some design variants, the fastening device 48, 49 can consist of separate fastening tabs that are connected permanently to the front end part 14 of the belted article 10, wherein the fastening tabs extend outside the edges of the belted article 10. The hook elements are in this case arranged on the fastening tabs.
When a belted article 10 is to be applied to a user, the belt portions 16 and 17 (forming the belt 15) is first fixed around the user's waist. The front end part 14 of the belt article 10 that hangs loosely is then led in between the user's legs, following which the fastening device 48, 49 is fixed to the belt portions 16 and 17 (i.e. the belt 15) on the stomach on the side of the belt 15 oriented away from the user. The hook elements of the fastening device are fixed in this case to loops arranged on the surface of the belt 15 oriented away from the user, e.g. belt portion surfaces 16a and 17a. A belted article is also conceivable in which the belt is connected to the front end part of the belt article. Such an article is applied to the user in the reverse manner, i.e. after the belt has been fixed around the user's waist, the loosely hanging rear end part is led in between the user's legs and fixed to the belt at the back on the side of the belt oriented away from the user.
To improve the fit of the belted article 10, the longitudinal edges 1,2 of the first covering layer 20 can be provided with leg elastic 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 belt article 10 more like textile multiple-use briefs/pants. The respective leg elastic 45 can consist of one or more elastic threads that in the extended state have been joined to the covering layer 20 by gluing, ultrasonic welding or the like. Alternatively, the respective leg elastic 45 can consist of elastic ribbon material 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.
The rear or front end parts 18, 14 of the belted article 10 can also be provided with so-called waist elastic 46 in the form of elastic elements arranged along a second transverse edge 5 or a first transverse edge 4 of the belted article 10 to give the belt article 10 a soft, flexible enclosure of the user's waist. In fig. 1, only the front end part 14 of the belt article 10 is provided with waist elastic 46. The waist elastic 46 consists of 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 belted article 10 around the user's waist. When the fastening device 48, 49 are fastened to the belt 15, it is suitable that the waist elastic 46 is tensioned in the transverse direction Y of the belt article 10 so that the front end part 14 has a smooth configuration over the user's stomach on use.
According to another aspect of the disclosure, the belted 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 layer can also exist. The second covering layer 30 can consist of a range of different materials, but most frequently it consists of 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 consist of a liquid- impermeable vapour-permeable material, a so-called breathable material. 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 belt article 10 that is oriented away from the user on use. The outside of the belt 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 belted 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 a belted 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.
According to one example embodiment of the disclosure, as shown in figs. 1-2, the belted 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 a belted article according to this example must be liquid-permeable. The belted 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 a belted 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 faeces. 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 fibres 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 fibres, various types of fluid-dispersing layers or fibres, dimensionally stabilising components, reinforcing fibres or the like.
Turning now to the figs. 3a-3c, there is depicted an enlarged view of a section of the belt 15, i.e. the first belt portion 16 and the second belt portion 17, of an article described in conjunction with in figs. 1 and 2. However, the details and features of the belt portions described in relation to figs. 3a-3c may likewise be incorporated in the example embodiments described in conjunction with figs. 4-6. As mentioned above, the first belt portion 16 of the waist belt is intended to be interconnected to the second belt portion 17 by the fastener 51 for securing to each other around a wearer of the belted absorbent article. Further, as described in relation to figs. 1 and 2, the second end portion 14 of the chassis comprises the fastening device 48, 49 for securing the second end portion 14 of the chassis to the belt portion so that the article assumes a pant-like shape with the belt portions forming a part of a waist portion of the pant. The fastening device 48, 49 typically comprises a set of two fasteners, as shown in figs. 1 and 2. However, it may also be provided as an extended piece of a fastener across a length of the second end portion, as seen in the transverse direction Y. The second end portion 14 of the chassis may be secured to any one of the belt portions 16, 17. Typically, the second end portion 14 of the chassis may be secured to both belt portions 16, 17.
Further, as shown in figs. 1 and 2, the first and second belt portions 16, 17 are folded over the body-oriented surface 21 to form the folded belt configuration prior to use of the article, whereby the first belt portion 16 is arranged on top of the second belt portion 17, i.e. the first belt portion 16 overlaps the second belt portion 17. In figs. 3a-3c, this type of folded belt configuration is illustrated by the belt portions in an exploded view for ease of illustrating the components of the belt portions.
As mentioned above, there is a belt-opening trigger zone 50 disposed on the first belt portion. The belt-opening trigger zone 50 is arranged adjacent the free end 11 of the first belt portion 16. In this manner, a wearer or caregiver is not only guided to identify the free end of the first belt portion when the belt portions are in the folded belt configuration, but also triggered to open up the belt portions, i.e. unfold the first folded belt portion, prior to place the belt and the article around the waist of the wearer. In other words, the belt-opening zone is adapted to identify the free end of the first belt portion when the belt portions are in the folded belt configuration to trigger a user or wearer to initially unfold the belt portions into an unfolded belt configuration. In this context, the unfolded belt configuration refers to a configuration in which each one of the belt portions are unfolded from the body-oriented surface of the chassis. A beltopening trigger zone arranged adjacent the free end of the first belt portion is also useful to distinguish the free end of the first belt portion from the other end of the first belt portion, which is permanently attached to the chassis.
It should be readily appreciated that the term “adjacent” as used in this context typically means that the belt-opening trigger zone 50 is arranged sufficiently close to the free end so that a user is capable of immediately locate the free end. Thus, the belt-opening trigger zone 50 should at least be arranged at the section of the first belt portion being located closer to the free end 11 than the side edge of the first belt portion being permanently attached to the chassis. The distance between the beltopening trigger zone 50 and the free end 11 may however vary depending on the dimensions of the belt portion and the chassis, and the general size of the article.
As shown in the example illustrated in the figs. 3a-3c, the fastener 51 is arranged on the first belt portion in-between the belt-opening trigger zone 50 and the free end 11. However, the fastener 51 may likewise be arranged at another location on the first belt portion depending on the type of article and the dimensions of the chassis and the belt portions.
Optional, although not strictly required, the location of the fastener 51, and the relative orientation thereof, is such that the corresponding mating fastener on the second belt portion 17 may entirely meet to form an interconnection. Thus, the size and orientation of the fastener on the first belt portion, as seen in the direction x and the direction y, typically corresponds to the size and orientation of the mating fastener on the second belt portion, as seen in the direction x and direction y. By way of example, the fastener is a so called refastenable fastener, i.e. a fastener that can be open and closed depending on the user’s or caregivers needs.
Typically, although not strictly necessary, the belt-opening trigger zone 50 defines a pointer 52 directing a user to the free end 11 of the first belt portion 16 when the belt portions are in the folded belt configuration. However, other types of designs are readily appreciated as long as the belt-opening trigger zone is capable of providing the example advantages mentioned above.
Moreover, in this example embodiment, the belt-opening trigger zone resembles the shape of an arrow directing a user to the free end of the first belt portion when the belt portions are in the folded belt configuration. However, other types of designs are readily appreciated as long as the belt-opening trigger zone is capable of providing the example advantages mentioned above.
In the example embodiments shown in figs. 3a-3c, the belt-opening trigger zone is printed on the exterior surface 16a of the first belt portion 16. However, the beltopening trigger zone may also be an embossed belt-opening trigger zone. In some design variants, the belt-opening trigger zone is a combination of a printed and an embossed belt-opening trigger zone.
In addition, or alternatively, the belt-opening trigger zone may be a label attached to the exterior surface of the first belt portion.
Typically, although not strictly required, a remaining belt section of the first belt portion 16 has an essentially uniform non-patterned exterior surface 16a. By way of an example, the remaining belt section of the first belt portion 16 is free from distinguishable indicators.
In some design variants, the belt-opening trigger zone 50 comprises a tactile region having a tactile characteristic different than the other parts of the first belt portion.
In some design variants, the belt-opening trigger zone 50 comprises a visual region having a colour characteristic different than the other parts of the first belt portion.
Fig. 3b depicts another example embodiment, in which the belt-opening trigger zone comprises a plurality of belt-opening trigger zone elements 50a and 50b.
Thus, in some design variants, the belt-opening trigger zone comprises a plurality of belt-opening trigger zone elements. As an example, each one of beltopening trigger zone elements are provided in the form of an arrow defining a pointer directed towards the free end of the first belt portion. Further, each one of belt-opening trigger zone elements may typically be arranged to form a pattern over a surface of the first belt portion. With “a pattern” is meant herein an organised arrangement of at least one belt-opening trigger zone element. Such a pattern may be formed by various types of belt-opening trigger zone elements.
The belt-opening trigger zone may have a length in the longitudinal direction of the belt of about 10-100 mm, preferably a length in the said direction of about 15-50 mm, still preferably a length in the said direction of about 25-40 mm.
In this context, it is to be noted that the transversal direction of the belt may correspond to the longitudinal direction of the article if the belt is arranged to extend perpendicularly from a line parallel to the longitudinal direction of the article. Analogously, the longitudinal direction of the belt may correspond to the transverse direction of the article if the belt is arranged to extend perpendicularly from a line parallel to the longitudinal direction of the article.
Typically, the belt-opening trigger zone is arranged on the exterior surface 16a of the first belt portion 16.
Fig. 3c depicts another example embodiment, in which a second belt-opening trigger zone 56 is disposed on the second belt portion 17. The second belt-opening trigger zone 56 is arranged adjacent a free end of the second belt portion. The second belt-opening trigger zone may incorporate any one of the examples, features, functions and/or arrangements as described in relation to the belt-opening trigger zone described in conjunction with fig. 3a and 3b above, except that the second beltopening trigger zone is arranged on the second belt portion instead of the first belt portion.
In some design variants, the whole of a part of the free end 11 adjacent a free end edge 11a is distinguished from the remaining parts of the article by colour, pattern or the like 55.
Further, in all example embodiments described herein, and in other possible example embodiments, a part of any one of the first and second belt portions 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 belt portion is here permanently attached to the first end portion 18 of the chassis. Analogously, an end portion 27 of the second belt portion is here permanently attached to the first end portion 18 of the chassis.
As mentioned above, the belted article is typically a disposable absorbent article such as a diaper and an incontinence guard. Further, the belted 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.
Other embodiments are possible where the belt-opening trigger zone is provided with randomly selected or varied patterns.
The belt-opening trigger zone is typically centrally arranged in the transversal direction of the belt. However, variants are conceivable wherein any desired asymmetry of the arrangement of the belt-opening trigger zone is possible.
In view of the above disclosure explaining how to provide the belt-opening trigger zone on the belt portion, it will be understood that the article is provided with improved ability in terms of triggering a user of the article to find the free end and unfold the belt portions from their folded configuration.
Although several of examples of the belt-opening trigger zone given in the illustrated examples display a pointer or an arrow, a belt-opening trigger zone may naturally be formed by other intermittent or continuous areas, having a trigger zone shape, e.g. a triangular pointer or the like.
Figs. 4-6 illustrate further example embodiments of the folded belt configuration prior to use of the article 10. Each one of the example embodiments illustrated in the figs. 4-6 may incorporate any one of the features, examples or alternatives described above in conjunction with the figs 1-2 and figs. 3a-3c as long as there is no contradiction to the examples of the ones described and illustrated in figs. 4-6.
Fig. 4 shows another example embodiment of the disclosure, in which at least one of the belt portions is folded in order to wrap up a length of the at least one belt portion. 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 belt portions 16, 17 attached to the chassis so that a first belt portion 16 and a second belt portion 17 extend on each side of the first end portion 18 of the chassis for securing to each other around a waist of a wearer of the article to form a belt having an exterior surface. Moreover, the first belt portion 16 here carries a fastener 51 (not shown) adapted to be attached to an exterior surface of the second belt portions 17. The second end portion 14 of the chassis 12 comprises the fastening device 48, 49 for securing the second end portion 14 of the chassis to one of the belt portions 16, 17 so that the article 10 assumes a pant-like shape with the belt portions forming a part of a waist portion of the pant. In addition, a belt-opening trigger zone 50 is disposed adjacent a free end 11 of at least the first belt portions 16. Typically, the belt-opening trigger zone 50 is disposed on at least the first belt portion and arranged adjacent a free end 11 of the first belt portion 16. The belt-opening trigger zone may be provided in any suitable way as described above in relation to the figs. 2 and 3a-c.
Furthermore, the first and second belt portions 16, 17 are folded over the chassis 12 to form the folded belt configuration prior to use of the article, so that the belt-opening trigger zone 50 is visible by the user when the belt portions 16, 17 are in the folded belt configuration.
In this example, the folded belt configuration is formed by having the second belt portion 17 folded over the body-oriented surface 21, although the second belt portion is illustrated in fig. 4 in an unfolded mode (or loose hanging mode). Also, in this folded belt configuration, the first belt portion 16 is folded over the body-oriented surface 21. In other words, when the belt portions 16, 17 are in the folded belt configuration prior to use, the first belt portion 16 is folded over the body-oriented surface 21.
In addition, as is clearly shown in Fig. 4, the first belt portion 16 having the beltopening trigger zone 50 is folded in order to wrap up a length of the belt portion 16. Typically, although not strictly required (and not shown), the second belt portion 17 is also folded in order to wrap up a length of the belt portion 17. Similarly, the second belt portion 17 may also be provided with a belt-opening trigger zone (although not shown). In this example 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 belt portion is less than half the transverse length of the chassis, as shown in fig. 4. However, the extension of the folded belt portion may be varied depending on type of article, type of belt, type of fold and/or desired length of the belt when being unfolded. It is appreciated that an even larger amount of folds can be used in order to fold a desired amount of belt material.
In one design variant, the first belt portion which is folded in an accordion-like fashion may even overlap the second belt portion to some extent.
It is also readily appreciated that the belt-opening trigger zone 50 may be arranged on either surfaces of the first belt portion as long as the belt-opening trigger zone 50 is visible by the user when the belt portions 16, 17 are in the folded belt configuration as described above.
In one design option, although not illustrated, at least the first belt portion 16 can likewise be folded over the garment-oriented surface 22 (when the belt portions 16, 17 are in the folded belt configuration prior to use).
Further (although not shown), when the belt portions 16, 17 are in the folded belt configuration prior to use, at least the first belt portion 16 is typically, although not strictly required, releasably attached to a part of the body-oriented surface 21.
Similarly, the second belt portion 17 is typically, although not strictly required, releasably attached to a part of the body-oriented surface 21.
Fig. 5 schematically shows another example embodiment of the disclosure, in which the belt portions 16, 17 are double folded over each other, typically in order to wrap up a length of each belt portion. As mentioned above, the article 10 comprises the body-oriented surface 21 facing the user during use and the garment-oriented surface 22 facing away from the user in use. The article further comprises a pair of belt portions 16, 17 attached to the chassis so that a first belt portion 16 and a second belt portion 17 extend on each side of the first end portion 18 of the chassis for securing to each other around a waist of a wearer of the article to form a belt having an exterior surface. Moreover, the first belt portion 16 here carries a fastener 51 (not shown) adapted to be attached to an exterior surface of the second belt portions 17. The second end portion 14 of the chassis 12 comprises the fastening device 48, 49 for securing the second end portion 14 of the chassis to one of the belt portions 16, 17 so that the article 10 assumes a pant-like shape with the belt portions forming a part of a waist portion of the pant. In addition, a belt-opening trigger zone 50 is disposed adjacent a free end 11 of at least the first belt portions 16. Typically, the belt-opening trigger zone 50 is disposed on at least the first belt portion and arranged adjacent a free end 11 of the first belt portion 16. The belt-opening trigger zone may be provided in any suitable way as described above in relation to the figs. 2 and 3a-c.
Furthermore, as illustrated in fig. 5, the first and second belt portions 16, 17 are folded over the chassis 12 to form the folded belt configuration prior to use of the article, so that the belt-opening trigger zone 50 is visible by the user when the belt portions 16, 17 are in the folded belt configuration.
As shown in fig. 5, the folded belt configuration is formed by the second belt portion 17 being folded over the body-oriented surface 21. Also, in this folded belt configuration, the first belt portion 16 is folded over the body-oriented surface 21 and over the second belt portion 17. This example is similar to the other examples described above, however, one difference between this example and the examples illustrated in figs. 3a-3c and 4, is that the belt portions are double folded over the body-oriented surface 21. That is, each one of the first belt portion 16 and the second belt portion 17 is double folded. Accordingly, each one of the first belt portion 16 and the second belt portion 17 is double folded over the chassis of the article. It should be readily appreciated that when the belt portions 16, 17 are in the folded belt configuration prior to use, the first belt portion 16 is also considered folded over the body-oriented surface 21. The example of the article of Fig. 5 allows providing a belted article with relatively long belt portions in that each one of the belt portions are folded in order to wrap up a length of the corresponding belt portion. In other words, the first belt portion 16 having the belt-opening trigger zone 50 is double folded in order to wrap up a length of the belt portion 16. Similarly, the second belt portion 17 is double folded in order to wrap up a length of the belt portion 17. Although not strictly required, the second belt portion 17 may also be provided with a belt-opening trigger zone.
Further, in this example embodiment, the first belt portion partly overlaps the second belt portion 17, as shown in fig. 5. As such, when the first and second belt portions 16, 17 are in the folded belt configuration prior to use, the first belt portion 16 partly overlaps the second belt portion 17.
In one design variant (not shown), the first belt portion 16 may entirely overlap the second belt portion 17.
The overlap between the belt portions typically extends in the direction X and direction Y of the article, as shown in fig. 5. In this example, the extension of the double folded first belt portion is more than half the transverse length of the chassis, as shown in fig. 5. Analogously, the extension of the double folded second belt portion is more than half the transverse length of the chassis, as shown in fig. 5. Flowever, the extension of a double folded belt portion may be varied depending on type of article, type of belt, type of fold and/or desired length of the belt when being unfolded.
In one design variant, the double folded first belt portion may not overlap the double folded second belt portion.
In one design variant, although not illustrated, at least the first belt portion 16 can likewise be folded over the garment-oriented surface 22 (when the belt portions 16, 17 are in the folded belt configuration prior to use).
Further (although not shown), when the belt portions are in the folded belt configuration prior to use, a part of the first belt portion is typically, although not strictly required, releasably attached to another part of the first belt portion. Analogously, a part of the second belt portion is typically, although not strictly required, releasably attached to another part of the second belt portion.
Fig. 5 also illustrates that the belt-opening trigger zone 50 in this example embodiment is arranged adjacent the side of the first belt portion being permanently attached to the chassis. Accordingly, the first belt portion is double folded over the surface 21 so that the belt-opening trigger zone 50 of the belt portion 16 defining the free end 11 is positioned adjacent the side of the first belt portion being permanently attached to the chassis. It is believed that for this type of folded belt configuration, the belt-opening trigger zone 50 ensures that the user identifies the free end of the belt portion and not the part of the first belt portion being permanently attached to the chassis.
Fig. 6 schematically shows another example embodiment of the disclosure, in which the second belt portions 17 is double folded over the body-facing surface 21, typically in order to wrap up a length of the belt portion, whilst the first belt portion 16 is only folded over the second belt portion, and further comprising the belt-opening trigger zone 50. As mentioned above, the article 10 has the 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 belt portions 16, 17 attached to the chassis so that the first belt portion 16 and the second belt portion 17 extend on each side of the first end portion 18 of the chassis for securing to each other around a waist of a wearer of the article to form a belt having an exterior surface. Moreover, the first belt portion 16 here carries a fastener 51 (not shown) adapted to be attached to an exterior surface of the second belt portions 17. The second end portion 14 of the chassis 12 comprises the fastening device 48, 49 for securing the second end portion 14 of the chassis to one of the belt portions 16, 17 so that the article 10 assumes a pant-like shape with the belt portions forming a part of a waist portion of the pant. In addition, the belt-opening trigger zone 50 is disposed adjacent a free end 11 of at least the first belt portion 16. Typically, the belt-opening trigger zone 50 is disposed on at least the first belt portion and arranged adjacent a free end 11 of the first belt portion 16. The belt-opening trigger zone may be provided in any suitable way as described above in relation to the figs. 2 and 3a-c.
Furthermore, as illustrated in fig. 6, the first and second belt portions 16, 17 are folded over the chassis 12 to form the folded belt configuration prior to use of the article, so that the belt-opening trigger zone 50 is visible by the user when the belt portions 16, 17 are in the folded belt configuration.
This example is similar to the example described in conjunction with fig. 5 above, however, one difference between this example and the one in fig. 5, is that the second belt portion is double folded over the body-oriented surface 21, while the first belt portion is folded over the second belt portion. Thus, as shown in fig. 6, the folded belt configuration is formed by the second belt portion 17 being double folded over the body-oriented surface 21 (the chassis). Also, in this folded belt configuration, the first belt portion 16 is folded over the body-oriented surface 21 and over the second belt portion 17. That is, the second belt portion 17 is double folded over the chassis, whilst the first belt portion 16 is folded over the second belt portion 17.
Accordingly, each one of the first belt portion 16 and the second belt portion 17 is folded over the chassis of the article. It should be readily appreciated that when the belt portions 16, 17 are in the folded belt configuration prior to use, the first belt portion 16 is also considered folded over the body-oriented surface 21. The example of the article of Fig. 6 allows for providing a belted article with a relatively long second belt portion in that the second belt portion is folded in order to wrap up a length of the second belt portion. The first belt portion 16 having the belt-opening trigger zone 50 is only folded over the chassis. Although not strictly required, the second belt portion 17 may also be provided with a belt-opening trigger zone 56.
Further, in this example embodiment, the first belt portion almost entirely overlaps the second belt portion 17, as shown in fig. 6. As such, when the first and second belt portions 16, 17 are in the folded belt configuration prior to use, the first belt portion 16 entirely overlaps the second belt portion 17.
In one design variant (not shown), the first belt portion 16 may at least partly overlap the second belt portion 17.
The overlap between the belt portions typically extends in the direction X and direction Y of the article, as shown in fig. 6. In this example, the extension of the folded first belt portion is more than half the transverse length of the chassis, as shown in fig. 6. The extension of the double folded second belt portion is also more than half the transverse length of the chassis, as shown in fig. 6. However, the extension of the double folded second belt portion and/or the extension of the folded first belt portion may be varied depending on type of article, type of belt, type of fold and/or desired length of the belt when being unfolded.
In one design variant, the folded first belt portion may not overlap the double folded second belt portion.
It is also readily appreciated that the belt-opening trigger zone 50 may be arranged on either surfaces of the first belt portion as long as the belt-opening trigger zone 50 is visible by the user when the belt portions 16, 17 are in the folded belt configuration as described above. Typically, the belt-opening trigger zone 50 is arranged on the surface of the first belt portion facing the user when the belt portions 16, 17 are in the folded belt configuration as described above.
In one design variant, although not illustrated, the first belt portion 16 and the second belt portion 17 may likewise be folded over the garment-oriented surface 22 (when the belt portions 16, 17 are in the folded belt configuration prior to use).
In this example, as illustrated in fig. 6, and when the belt portions are in the folded belt configuration prior to use, a part of the first belt portion is typically, although not strictly required, releasably attached to a part of the second belt portion.
As an example, the first belt portion 16 is here releasably attached to the inner surface 19a of the second belt portion 17 by a breakable bond.
Analogously, a part of the second belt portion is typically, although not strictly required, releasably attached to the body-oriented surface of the chassis (or article).
As an example, the second belt portion 17 is here releasably attached to the body-oriented surface 21 by a breakable bond.
Fig. 6 also illustrates that the belt-opening trigger zone 50 in this example embodiment is arranged adjacent the side of the second belt portion being permanently attached to the chassis. Accordingly, the first belt portion is folded over the surface 21 so that the belt-opening trigger zone 50 of the first belt portion 16 defining the free end 11 is positioned adjacent the side of the second belt portion being permanently attached to the chassis. It is believed that for this type of folded belt configuration, the belt-opening trigger zone 50 ensures that the user identifies the free end of the first belt portion and not the part of the second belt portion being permanently attached to the chassis.
As mentioned above, in all example embodiments described herein, and in other possible example embodiments, a part of any one of the first and second belt portions 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 belt portion is here permanently attached to the first end portion 18 of the chassis. Analogously, an end portion 27 of the second belt portion is here permanently attached to the first end portion 18 of the chassis. Also, as mentioned above, the belted article is typically a disposable absorbent article such as a diaper and an incontinence guard. Further, the belted article 10 in the example 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.
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 fibres may be in the form of endless fibres or fibres prefabricated with an endless length, as synthetic fibres produced in situ or in the form of staple fibres. Alternatively, they may be made from natural fibres or from blends of synthetic fibres and natural fibres.
By “absorbent article” is meant an article that absorbs or is adapted to absorb bodily fluids, such as urine and/or blood.
