Definitions

  • the present invention relates to articles, such as disposable absorbent articles or disposable underwear such as for receiving bodily exudates such as faeces and urine.
  • JPH 10-295723 an article is described wherein a detachable excretion treatment sheet is positioned in the rear portion of an article, forming a dam which is activated by means of a drawstring, which is running freely in a drawstring tunnel, thusly allowing easier and cleanlier removal and disposal of a faeces loaded diaper.
  • WO2011064272 A2 Another approach towards separation of bodily exudates is described in WO2011064272 A2 (Schmitz).
  • An article to be worn on the lower torso of a wearer, such as pants or diapers has a flexible faeces separation member, such as a faeces trap sheet, which is attached in a particular way such that an effective separation of faeces and skin respective genitals can be achieved.
  • the present invention is an article to be worn on the lower torso of a wearer with an article width (y-) direction corresponding to the left-right orientation of the wearer during use, an article length (x-) direction corresponding to a line running from the front waist through the crotch to the rear waist of the wearer during use, and an article thickness (z-) direction perpendicular to the x- and y- direction.
  • An article crotch point is positioned on the longitudinal centreline and in the crotch region of the article.
  • the article comprises a topsheet material comprising a first surface adapted to generally face towards the wearer during use and of which at least a portion is adapted to be in contact with the skin of the wearer during use and an opposite surface, facing generally away from the wearer during use.
  • the article further comprises a backsheet material positioned away from a wearer during use and having a first surface oriented towards the opposite surface of the topsheet, defining an overall article length.
  • the article further comprises a drawstring system for longitudinally foreshortening the topsheet relative to the overall article length, which comprises
  • drawstring fixation positioned in the proximity of a longitudinal end margin of the article and being adapted to allow fixation of the drawstring by a user.
  • the drawstring tunnel system may be selected from the group consisting of
  • At least one separate drawstring tunnel material connected longitudinally to the topsheet.
  • the article may comprise a single drawstring tunnel positioned essentially along the longitudinal centre line of the article or a pair of drawstring tunnels positioned essentially symmetrically to the longitudinal centre line, optionally parallel to each other.
  • the article may further comprise one or more elements selected from the group consisting of
  • drawstring gripping means preferably in the form of a slit, cut out or fold-over portion in the topsheet or backsheet, positioned in the proximity of the end margin of the article longitudinally opposite of the first drawstring connecting region relative to the crotch point;
  • drawstring tunnel opening positioned in the crotch region, preferably the perineal region of the article adapted to allow the drawstring to be pulled out of the drawstring tunnel upon activation.
  • the drawstring connection may be selected from the group consisting of
  • the drawstring fixation may be selected from the group consisting of
  • the topsheet may further comprise at least one passageway positioned along the longitudinal centreline of the article and laterally between the pair of drawstring tunnels in either one or both of the anal and genital regions of the article, the passageway(s) being adapted to allow faeces or menses or urine or urine or menses releasing body organs, respectively, to pass through.
  • the topsheet may be essentially liquid impermeable, preferably a hydrophobic nonwoven material.
  • the second drawstring connection may be adapted to allow fixation of the drawstring(s) by a user such that a longitudinally (x-directionally) extending line running from the front end of the article along the drawstring directly to the rear end of the article is at least 10 mm shorter than the overall article length.
  • the foreshortening of the topsheet may form a flap in the perineal region of the article, which may further be connected to the backsheet directly or via a further material, if present, thereby forming a barrier flap.
  • the article may further comprise a first passageway in the anal region and a second passageway in the genital region, wherein the barrier flap is positioned in the perineal region, adapted to allow separation of faeces from the genital region.
  • the present invention is a method for foreshortening a topsheet of an article comprising the steps of
  • Fig. 1 A schematically depicts a lower torso of a wearer.
  • Fig. IB an C show schematically an execution of an article according to the present invention in a pre use (extended topsheet) and an in-use (foreshortened topsheet) configuration.
  • Fig. 2A to C depict schematically an article according to the present invention with a pair of drawstrings.
  • Fig 3 depicts schematically an article according to the present invention further comprising an absorbent core.
  • Fig. 4 depicts schematically an article according to the present invention further comprising passageways in the topsheet.
  • the present invention relates to articles, typically worn by humans on the lower torso, such as pants style articles or diapers.
  • the articles according to the present invention are particularly adapted to provide improved fit and skin health by allowing to separate a skin contacting topsheet from a backsheet, in particular allowing an improved functionality with regard to the handling of bodily discharges such as faeces and / or urine or menses as may be discharged thereto.
  • the articles according to the present invention comprise absorbent elements so as to immobilize liquid bodily discharges, however articles may also have no or only very limited liquid absorption capability, such as when being adapted to receive solid excrements only.
  • the present invention relates to articles which may be closed pants or pants-style articles or to articles, which are open diapers and which may be brought into a closed pants-style form upon donning such as conventional taped diapers. Included in the term “articles” are pre-forms of such articles, which may require addition of certain elements or performance of certain process steps to be functional as an article.
  • An article according to the present invention may have an "in-use configuration” or a "pre -use configuration” respectively post-manufacturing configuration, which may differ in the geometric or spatial arrangement of certain elements thereof.
  • FIG. 1 By referring to Fig. 1 , the portions or regions of an article according to the present invention and their relation to the geometry of a wearer are explained.
  • Fig. 1A schematically depicts the lower torso 15 and a leg 20 of a wearer 10, with a front waist region 30, a rear waist region 40, and a crotch region 50.
  • the crotch region of the wearer comprises in a longitudinal arrangement the genital region 80 (genitals not shown), the perineal region 70 and the anal region 60 (anus not shown).
  • the crotch region comprises laterally, i.e. y-directionally outwardly positioned regions and a median crotch region there between, including the longitudinally extending centreline.
  • the "crotch point" 75 refers to a point along the longitudinally extending axis of the article corresponding to a point in the perineal region of a wearer between the anus and the scrotum, or the labia, respectively.
  • the crotch point of an article can be determined by placing an article on a wearer of the physical size for which the article is designed and who is in a fully upright standing position with his or her feet a shoulder width apart and then placing an extensible filament around the upper thighs in a figure eight configuration. The point in the article corresponding to the point of intersection of the filament is considered to be the crotch point of the article.
  • the length of the perineal region has a person to person variability, and is also somewhat dependent on the gender. Typically a range of 2.5 cm and 7 cm covers most of the adults, with a medium length of between 4 cm and 5 cm, both ranges being applicable to female and male persons. For babies, the perineal length is typically shorter, though not below about 1 cm. Thus, typically, the crotch point on a wearer is positioned between about 0.5 cm and about 4 cm forwardly of the forward end of the anus.
  • FIG. 1 an article according to the present invention is shown in an in-use configuration (Fig. IB) and a pre-use configuration (Fig. 1C).
  • the article exhibits a width or y- dimension 1007, which during use corresponds to the left-right direction of the wearer and a thickness or z-direction perpendicular to the x- and y- direction.
  • the longitudinal, x- axis of the article (1002) corresponds during use to a line running from the front waist region through the crotch region to the rear waist region of the wearer.
  • the article comprises a topsheet 1200, following the body contours as shown in Fig.
  • the article 1000 comprises a front waist region 1112 and a rear waist region 1118.
  • the topsheet 1200 and the backsheet 1300 are connected to each other in the waist regions, and essentially unconnected at least in a portion of the crotch region 1115.
  • the topsheet 1200 is foreshortened relative to the backsheet, thereby allowing to create a space between the topsheet and the backsheet at least in the crotch region.
  • this space does not necessarily need to be a free void space which is present all the time, but it may simply be an arrangement of the topsheet and the backsheet that allows them to be spaced apart, such as when exudates are positioned therein. .
  • Fig 1C shows an article as in Fig. IB in a pre-use configuration. From a manufacturing point of view it is desirable to have during manufacturing the topsheet and the backsheet exhibit the same length, Fig. 1C shows with Cartesian coordinates with a length or x- direction 1102, a width or y-direction 1107, a well as with a longitudinal centreline 1103, an expanded topsheet 1200, connected in the front (1112) and rear (1118) waist regions to the backsheet 1300, here shown as intermittent connecting regions 1512 and 1518, respectively
  • the article further comprises a crotch region 1115, comprising a genital region 1114, a perineal region 1116 with crotch point 1119 and an anal region 1117.
  • An article according to the present invention comprises at least two material layers as topsheet and backsheet. Beyond the requirements that apply to articles to be worn on the lower torso of a wearer, such as not compromising on comfort or health aspects there are no particular constraints resulting from the application of the present invention to such articles. Routine adaptation to the specific application will determine strength, softness, air- and liquid permeability, etc of the materials. In particular when the articles are intended for large scale production, the materials are preferably web materials.
  • web relates to any material which is essentially endless or continuous in one direction (generally denoted as “x-direction” or “machine direction”). Webs are often, but not necessarily, stored, supplied or used in roll form and thusly also sometimes denoted “roll goods”. Whilst these are then not “endless” in the strict sense of the word, their extension in this x-direction is significantly larger than in any other direction. By combining consecutive rolls or other batches, (“splicing”) such webs can be considered “endless” for all practical purposes.
  • Webs may be transported in a "batch” form, such as when a roll thereof is shipped, or they may follow a "web path", such as when the webs are unwound from a roll, as described hereinafter.
  • Typical examples for webs are - without implying any limitation - plastic films or foils, textiles, non-wovens, nets, scrims.
  • At least a portion of a first web material is intended to be generally in contact with the skin of the wearer with a first surface and thus is typically referred to as "topsheet". Its second opposite surface of the first web material faces away from the wearer.
  • the term "generally” refers to the fact, that - at least in an in-use configuration - a part or portion of the topsheet - such as portions along the longitudinally extending side margins may be folded away from the surface, such that they do not touch the skin of the wearer.
  • a topsheet is the portion of the article, which faces towards the wearer at least in the waist regions.
  • the topsheet is preferably compliant, soft feeling, and non-irritating to the wearer's skin and may be manufactured from a wide range of materials, such as porous foams; reticulated foams; apertured plastic films; or woven or nonwoven webs of natural fibres (e.g., wood or cotton fibres), synthetic fibres (e.g., polyester or polypropylene fibres), or a combination of natural and synthetic fibres. If the topsheet includes fibres, the fibres may be spunbond, carded, wet-laid, meltblown, hydroentangled, or otherwise processed as is known in the art.
  • the topsheet may be a composite material, such as when comprising an open net or scrim structure in combination with a spunbonded web. Such a composite may also have discontinuities, such as when a spunbonded web comprises a cut out and is overlying a continuous net.
  • the topsheet may be made of a hydrophobic material and may - optionally only in certain regions - be treated to be hydrophilic so that liquids will transfer through the topsheet more rapidly.
  • the topsheet can be rendered hydrophilic by treating it with a surfactant or by incorporating a surfactant into the topsheet, both methods being well known in the art.
  • the article further comprises a second web material positioned such that its first surface is oriented towards the second, opposite surface of the first web material. During use, the second, opposite surface of the second web material faces away from the wearer. Often, such a second web material is referred to as "backsheet".
  • the backsheet forms generally the outer surface of the article during use, and thus the x- directional length of the backsheet is considered the overall length of the article.
  • the backsheet is often impervious to liquids (e.g., urine) and often comprises a thin plastic film such as a thermoplastic film having a thickness of about 0.01 mm to about 0.1 mm.
  • suitable backsheet materials may include breathable materials which permit vapours to escape from the article while still preventing exudates from passing through the backsheet.
  • Exemplary breathable materials may include materials such as woven webs, nonwoven webs, composite materials such as film-coated nonwoven webs, microporous films, all of which are well known in the art.
  • the webs may also be overfolded together, such as when their longitudinal side margins are folded over along a longitudinally extending fold line such that the first surfaces of the first web are contacting each other.
  • an article according to the present invention may comprise further elements, features, and materials, such as may typically be used in articles such as disposable absorbent articles.
  • the article may be used to capture excrements without having any absorptive capacity. Then the article may be just equipped with side closures to fit the articles.
  • the article comprises liquid absorbent elements, often also referred to as absorbent cores, as may be selected over a very wide range of executions as being well known in the art.
  • An absorbent element may be a composite material, such as by comprising various materials, such as particulate material, such as superabsorbent particles, fibrous materials, such as cellulose fluff, or other materials, layers or webs, such as adhesives, tissues, nonwovens, etc, all of which are well known in the art.
  • the absorbent element exhibits at least in the crotch region a sufficient z-directional integrity and strength so as to allow connecting of a topsheet thereto, in particular when the absorbent elements are at least in parts of the crotch region connected to the backsheet.
  • This integrity may be enhanced inherently or by added integrity enhancer, such as adhesive or binder fibres, or heat or pressure bonding.
  • An absorbent element may be formed in-line or may be produced off-line and be brought to the manufacturing facilities, where it may be combined with further materials.
  • the absorbent core may be a so called air-laid absorbent material, often also referred to as roll-stock core.
  • An article according to the present invention can be used without particular closure systems or fastening tapes and may be immobilized on the body by normal underwear or specially designed pants like net pants, also well known in the art.
  • the article may be held to the body by conventional closure elements such as well known closure tapes of the adhesive and/or mechanical engagement type.
  • the article may also form a pants-style article with side closures which may be permanently connected or which may be releasably pre-fastened during manufacturing but which may be non-destructively adjusted by the user.
  • the article further may comprise side panels in side panel regions, which extend laterally outwardly of a centre piece along the width y-direction of the article at least in the front and / or rear waist region.
  • this refers to an article in its in-use configuration.
  • the side panels - if present - may be folded or stacked so as to overly the centre region, but are nonetheless considered as "extending laterally outwardly”.
  • the article according to the present invention is essentially symmetrical to its longitudinally extending centreline.
  • the article topsheet, backsheet and an absorbent element there between may form a centre piece of an article, which may be combined with leg hoops and/or side panels, such described in WO06/102974A1 or WO08/037281.
  • An article according to the present invention may further comprise various other functional or aesthetic elements, such as side panels, barrier leg cuffs, leg hoops, or printing, all well know as such in the art.
  • the present invention can be very advantageously applied if the topsheet comprises at least one passageway, and if it is urged away from the backsheet towards the user at least in the region of this passageway.
  • a passageway is a discontinuity in the topsheet allowing bodily exudates, especially faeces, urine or menses, or such body exudates emanating body parts, to pass through the topsheet.
  • a passageway may be a hole or an aperture in the topsheet, such by a portion being cut out, or a slit extending x-or y- directionally, whereby the side margins are adapted to not dislocate z-directionally during use, but x and/or y- directionally upon action of a slit opening force.
  • a generally longitudinally extending slit may have one or more generally cross-directionally extending slits at it longitudinal ends, and the longitudinal side margins may be overfolded.
  • the topsheet may be a composite material, such as an open net or a scrim allowing for example faeces to penetrate through, and a spunbonded web facing towards the wearer. A passageway may then be formed by an opening in the spunbonded web whilst the net or scrim material remains unchanged.
  • the term "generally extending in longitudinal direction” refers to a situation, where the projection of the line onto the longitudinal centreline is longer than the projection onto the cross-directionally extending straight line, and vice versa.
  • a first execution of a passageway is adapted to allow faeces to penetrate through.
  • a passageway useful in the present invention may be formed by a hole or aperture having its largest extension in the x- or y- direction of the article (including circular openings).
  • a passageway is formed by one or more slits or cut-lines, this may extend generally in the x- or y- direction of the article, with the positioning of the drawstring being adapted accordingly.
  • a faeces passage way should be positioned along the longitudinal centreline of the article rearwardly of the perineal region of a wearer.
  • the faeces passageway should have a longitudinal extension of at least the length of the anus, and this should be preferably at least 2 cm in case of being intended for babies, and 4 cm in case of adults.
  • the faeces passage should exhibit at a cross-directional opening during use, i.e. in its in-use configuration, of at least 2 cm.
  • a second execution of a passage way is adapted to allow urine or menses to pass through.
  • Such a passage way should be positioned forwardly of the perineal region and should be positioned in the genital regions and have in the in-use configuration a dimensions of at least 3 cm in length and 1 cm in width.
  • a variant of this execution may allow genitals, such as penis and scrotum, to pass through
  • An article according to the present invention may comprise either one of the described executions for a passageway or both.
  • topsheet is urged away during use from the underlying layer.
  • the present invention does not rely on elastification but rather exploits geometrical effects by foreshortening the topsheet relative to the backsheet. It is a particular element of the present invention that the topsheet is foreshortened relatively to and independent of the backsheet, or another material layer connected to the backsheet, by means of a drawstring system.
  • a drawstring system comprises at least one drawstring, a drawstring tunnel, a drawstring connection, a drawstring fixation , optionally a tunnel connection , and optionally a drawstring gripping means.
  • the drawstring material should generally satisfy the requirements for a garment to be worn on the lower torso, and thus be sufficiently pliable and non-irritating to the skin.
  • Preferably is a flat material, i.e., its cross-directional extension exceeds its z-directional extension and preferably it is a z-directionally thin material, so as to not bear against the skin of the wearer.
  • the drawstring material should preferably withstand normal in-use forces, as occur during manufacturing, donning, and wearing.
  • a drawstring material preferably exhibits a tensile strength of at least 10 N/ 50 mm along the x-direction of the article.
  • the drawstring material is a web material, and may be cut of another web material as being used in the manufacture of the article, such as of the topsheet or the backsheet.
  • drawstring length corresponds to the length of the article, respectively the backsheet.
  • the drawstring tunnel extends predominantly longitudinally, i.e. a straight connecting line between the two ends of the tunnel has an angle of less than 45° to the longitudinal centre line of the article, preferably it runs parallel thereto.
  • a tunnel has a tunnel centre-line, which may be curvilinear, although straight centrelines are preferred from a manufacturing point of view.
  • a drawstring tunnel may form a complete encasing of the drawstring, but the tunnel may be discontinuous and the drawstring may run between two tunnel sections, if this region does not require guiding of the drawstring material, or if this guiding is accomplished by other means.
  • the drawstring tunnel may follow a non linear trajectory in relaxed (pre use) mode, its distance to the product centreline preferably being minimum in the area of generally x- directional passageway(s), such that upon tensioning and stratifying of the drawstrings the passageways are opened in y-direction.
  • Drawstring tunnels may be interrupted at generally y-directional passageways, and the drawstring material may be fixed to the TS and optionally to the tunnel material close to the margins of the slit, such that upon tensioning of the drawstrings the topsheet is urged away from the backsheet or an underlying layer, and the y-directional slit is opened.
  • the drawstring tunnel extends essentially along the length of the drawstring, though at the ends of the tunnel drawstring gripping means in the form of cutting out portions of the tunnel material may be present.
  • the material for forming a drawstring tunnel should generally satisfy the same requirements as topsheet, backsheet or drawstring.
  • the drawstring tunnel needs to be - at least in certain sections thereof - connected to the topsheet. For particular applications it is preferred that the drawstring tunnel is positioned underneath the topsheet, i.e. oriented away from the wearer during use.
  • the drawstring may be formed of a separate material or by other elements present in the article.
  • the drawstring tunnel is formed by a drawstring tunnel material attached to the topsheet of the article and being connected along its longitudinally extending side margins thereto.

  • the drawstring tunnel may be formed by longitudinally folding the topsheet, e.g. in the form of a double z-fold symmetric to the tunnel centre-line such that the topsheet can be connected at the edges of the z-fold, such as by adhesive or melt fusion bonding, optionally with a slight overlap of the topsheet material, or an additional connecting materials, such as an adhesive tape.
  • the topsheet may be longitudinally slit and the two sides are positioned overlappingly relative to the centreline of the article, thusly forming a tunnel upon connecting as in the first execution.
  • the drawstring tunnel may comprise in certain regions tunnel openings for the drawstring in its upper layer, which is oriented towards the user.
  • the drawstring may be positioned in the drawstring tunnel prior to connecting the tunnel to the topsheet. Alternatively, insertion of the drawstring and connecting of the tunnel are done simultaneously.
  • the drawstring In order to allow foreshortening of the topsheet by the present drawstring system and in contrast to a system such as described in the aforementioned JPH 10-295723, the drawstring must be connected to the topsheet by a connection in order to anchor the drawstring when being pulled at the other end.

  • the drawstring is activated and the topsheet foreshortened.
  • the foreshortening can have different effects, the principles of which are explained in the following:
  • the user may pull at the front end, optionally aided by the gripping.
  • the topsheet will then be shirred predominantly in the front region of the article, but can move away from the backsheet over the full length. The more the connecting point is moved from the rear towards the front, the more the shirring will be limited to the front region.
