Definitions

  • the invention relates to a disposable hygiene article or surgical covering item, or surgical garment for single use, such as an incontinence diaper, incontinence pad, surgical drape, or surgical coat, comprising a composite nonwoven fabric, that is provided with at least one nonwoven fabric component and another nonwoven fabric or foil component.
  • the first nonwoven fabric component is attached to the other nonwoven fabric or foil component in at least some areas by means of a joining pattern encompassing discrete ultrasonic welding points in order to form the composite nonwoven fabric.
  • the joining pattern extends in a first direction and a second direction that runs perpendicular thereto, the distance in the first direction being longer than the distance in the second direction. At least some sections of the joining pattern are not rectilinear.
  • incontinence products such as incontinence diapers
  • lateral barriers standing toward the user during use called cuff elements
  • cuff elements lateral barriers standing toward the user during use
  • the joining of nonwoven fabric and/or foil components by means of ultrasonic welding devices is generally known.
  • a joining pattern comprising discrete ultrasonic welding points can be implemented in a continuous, that is, never-ending production machine for nonwoven articles of the type stated above by using a contour roller rolling in the machine direction and an anvil made to vibrate in the ultrasonic range, which is termed a sonotrode.
  • the contour roller and sonotrode form a gap between them through which the weldable components to be joined are fed during the continuous production process.
  • the nonwoven fabric or foil components are then welded by transfer of the vibration energy on the raised areas of the contour roller.
  • the strength of the weld can be adjusted by varying the distance between the sonotrode and the contour roller and by controlling the vibration of the sonotrode.
  • the applicant has ascertained that, in particular, on fast-operating production machines, it is extremely difficult to achieve a uniformly secure weld without damaging the components if the area of the weld varies greatly in the machine direction, because this necessitates very frequent variation in control of the welding device or its sonotrode. It is extremely difficult to almost impossible to achieve a stable operating condition. If, on the other hand, the area of a joining pattern varies little or not at all in the machine direction, for example, if it does not vary in the circumferential direction of the contour roller and, for example, comprises concentric embossing lines or embossing points on the contour roller, the problem described above does not occur because the welded area does not change so rapidly in the machine direction.
  • the joining pattern is oblique with respect to the machine direction or comprises oblique sections, the proportion of the welded area in the machine direction will vary greatly and the problems described above will occur. If, for example, on one product, the joining pattern comprises arc-shaped areas with tight curvature with respect to the machine direction, achieving process reliability in the welding of nonwoven fabric components poses a problem. If this problem is not solved, unwelded points or damage to the nonwoven fabric or foil components due to overwelding will occur. In either case, correct functioning of the article being produced is jeopardized. Extremely short control cycles in operating the ultrasonic welding device can also result in the device overshooting and frequently causing direct contact between the contour roller and the sonotrode. This results in damage to the device, considerably reducing its service life. The sonotrode and contour roller then require frequent replacement due to the high wear caused by direct contact between the two machine components.
  • the object of this invention is to provide a hygiene article or a surgical covering item or surgical garment of the type described above with which the problems described above do not occur, while nevertheless permitting production of a joining pattern of discrete ultrasonic welding points that varies in the machine direction.
  • a standing cuff element according to a joining pattern that oscillates in the form of arcs with respect to the machine direction or generally to join weldable nonwoven fabric or foil components of the article stated above fed in as flat material without being limited to a joint that is precisely rectilinear in the machine direction.
  • damage to components being welded together during the welding process and partially deficient welding of the components must be precluded.
  • damage to the ultrasonic welding device must be avoided and a long service life ensured in conjunction with fast-operating production machines.
  • This object is inventively achieved in an article of the type stated above by ensuring that the index of variation of the area seized by the ultrasonic welding points is no more than 40%.
  • the solution is to design the joining pattern of the ultrasonic welding points in such a way that the area seized by the welding in the machine direction does not vary so much that the problems described above occur. For example, this can be achieved by variation and appropriate disposition of the number of ultrasonic welding points per unit area, that is, e.g. by selecting the distance between the ultrasonic welding points and/or by varying the respective area of the ultrasonic welding points.
  • the index of variation of the area seized by the ultrasonic welding points is calculated as follows:
  • the article in accordance with the invention is considered divided into 5-mm wide longitudinal sections in the first direction. These longitudinal sections therefore extend over 5 mm in the first direction, which is also the machine direction, and perpendicular thereto in the second direction, which is the transverse direction on the product.
  • Each of these sections extending 5 mm in the longitudinal direction encompasses a number of ultrasonic welding points, each of which constitutes a welded proportion of the area. It is possible to calculate the welded area A i of each 5-mm section (sum of the areas of the individual ultrasonic welding points in a 5-mm section).
  • a mean value ⁇ of the area A i seized by the ultrasonic welding points of each section It is also possible to calculate a mean value ⁇ of the area A i seized by the ultrasonic welding points of each section. For example, it is possible to divide an 820-mm long article into 164 such 5-mm sections in the first direction. For each section, it is possible to calculate the welded area A i and from these 164 A i values, it is then possible to calculate the arithmetic mean ⁇ of the welded area of the 5-mm sections. A value s can be calculated from these according to the following formula:
  • the range of the index of variation of the area seized by the ultrasonic welding points of no more than 40% that is stated in the claims is suitable, in particular, for the machine velocities relevant here of 100 m/min to 1000 m/min, in particular, of 150 m/min to 700 m/min, to ensure process reliability of the ultrasonic weld joint between nonwoven fabric components and/or foil components of the articles in question here. It has proven especially advantageous if the index of variation of the area seized by the ultrasonic welding points is no more than 35%, in particular, no more than 30% and further, in particular, no more than 25% (claim 2 ).
  • a cuff element is a lateral barrier formed from a flat material that is raised from the substrate mostly due to elastification, in particular, toward the body of the user and thus provides a leakage barrier, chiefly at the sides of the article.
  • this cuff element is joined to further (chassis) nonwoven fabric or foil components of the article by an inventively constituted joining pattern of ultrasonic welding points.
  • the cuff element therefore advantageously also comprises the first nonwoven fabric component (claim 4 ).
  • the article according to the claims is a hygiene article for single use, it proves advantageous if the article comprises a topsheet that is permeable at least in some areas, a backsheet that is impermeable at least in some areas, and a storage core that absorbs body fluids and is disposed between the two (claim 5 ).
  • the other nonwoven fabric or foil component it can be advantageous for the other nonwoven fabric or foil component to be the topsheet or the backsheet, so that a preferably additionally provided cuff element with its first nonwoven fabric component is attached to the topsheet or backsheet by the inventive joining pattern of ultrasonic welding points (claim 6 ).
  • the joining pattern comprises a first partial joining pattern that, at least in areas, constitutes a cuff base, that is, an area along which the cuff element is attached to the further nonwoven fabric component or foil component (claim 7 ).
  • a first partial joining pattern that, at least in areas, constitutes a cuff base, that is, an area along which the cuff element is attached to the further nonwoven fabric component or foil component (claim 7 ).
  • the cuff base constituted in some areas by the said first partial joining pattern can additionally be constituted or limited in some areas by a second partial joining pattern that is largely rectilinear and, in particular, largely extends parallel to the first direction (claim 8 ).
  • a partial joining pattern is referred to as largely rectilinear when, over a length of 200 mm in the first direction, an extension in the second direction of no more than 6 mm can be ascertained.
  • the cuff base is constituted at least in sections by the first partial joining pattern, the second partial joining pattern and a third non-rectilinear partial joining pattern (claim 9 ).
  • the second partial joining pattern is disposed preferably between the first and the third partial joining pattern (claim 10 ).
  • the result is therefore a cuff base that, in a front area and in a rear area of the article, extends transverse to the longitudinal direction, in particular, curved in the shape of an arc with respect to the longitudinal direction and, in the intermediate area, is largely rectilinear and, in particular, parallel to the first direction.
  • Such a configuration proves especially advantageous, particularly for hygiene articles for single use, such as incontinence diapers, incontinence pads.
  • the invention makes it possible to dispose the cuff elements relatively far toward the outside in the transverse direction in a front and rear region of the article and then to have them curve inward toward the crotch area.
  • the cuff elements or the cuff base or cuff base lines then advantageously extend largely parallel and have a smaller distance between them in the transverse direction (second direction) than in the front and rear areas.
  • the joining pattern in the first direction is considered virtually in three sections of equal length, that is, is divisible into a start section, an adjoining center section, and an end section adjoining the center section and the index of variation of the area of the start section and/or of the end sections seized by the ultrasonic welding points of the joining pattern is no more than 40%, in particular, no more than 35%, further, in particular, no more than 30%, further, in particular, no more than 25% (claim 11 ).

  • this index of variation of the area seized by the ultrasonic welding points 30 should be no more than 40% in the first direction 32 .
  • FIGS. 7 and 8 two different joining patterns of discrete ultrasonic welding points are examined below. As can be seen, it is a joining pattern for fixing cuff elements 14 shown in FIGS. 1 and 2 , that is, fixing the nonwoven fabric component 16 of these cuff elements 14 to a further nonwoven fabric or foil component 10 of a hygiene article. The joining pattern of one of the two cuff elements 14 of the hygiene article was considered.
  • FIG. 7 shows along the abscissa the form of the joining pattern under consideration of ultrasonic welding points that have a small distance between them in a first area 27 and a larger distance between them in a second area 29 .

  • the joining pattern 36 is divided into a start section 50 , a center section 52 , and an end section 54 that each extend over a third of the extent of the joining pattern 36 in the longitudinal direction, the following values are obtained for these sections 50 , 52 , 54 when the N/3 5-mm sections contained in them are each evaluated in isolation:
  • FIG. 8 An inventive joining pattern 36 is shown in FIG. 8 .
  • the following values are obtained when the N/3 5-mm sections contained in sections 50 , 52 , 54 are each evaluated in isolation:
  • a first partial joining pattern 60 that forms a part of a cuff base 28 and extends curved in the shape of an arc is formed from a set of several curves 62 .
  • the term curve is used here for a series of successive discrete ultrasonic welding points 30 (as can be seen in FIG. 5 ).
  • This set of curves 62 is, for example, disposed in a range of approx.
  • the curves 62 are curved in the shape of an arc, and the distance between increases in the first direction 32 .
  • the area proportions A i of the 5 mm-sections in the first direction 32 do not vary as much, for example, as in the case of the joining pattern according to FIG. 7 . In total, a very much lower index of variation of the area seized by the ultrasonic welding points results.
  • a first possibility is to keep the radius of curvature of curved partial joining patterns as large as possible, that is, not to permit tight curvature.
  • a further possibility which is shown in FIG. 8 , is the formation of curved partial joining patterns in the form of multiple curves or series of ultrasonic welding points, whose distance from each other is especially variable. Also, the distance between the individual ultrasonic welding points, in particular, those of a series could be varied. Also the area of the individual ultrasonic welding points or protrusions on the contour roller could be varied, in particular, additionally. Moreover, the disposition and the distance between the ultrasonic welding points in a second area, that is, where the ultrasonic welding points are further apart, can be varied.
  • FIG. 8 shows a second partial joining pattern 64 that is largely rectilinear and extends in the first direction 32 . It is said to extend largely in the first direction 32 if, over a length of about 200 mm in the first direction 32 , an extent in the second direction 34 of no more than 5 mm can be determined.
  • a third partial joining pattern 66 is adjoined to this, which, like the first partial joining pattern 60 , extends curved in the shape of an arc and comprises a set of several curves 62 . It therefore also has a component in the second direction 34 .
