Definitions

  • This invention relates to absorbent articles, and particularly to a diaper including a part constructed to prevent leakage of fecal material through a wearer's gluteal groove at the rear of the diaper. While the diaper is de ⁇ scribed herein in its use by a child, it may also be used by adults.
  • a disposable diaper usually includes a core of absorbent material enclosed on its outside by a liquid impervious backsheet and on its inside by a liquid pervious topsheet. Such a diaper usually also includes elastic leg cuffs around the wearer's legs and an elastic waist band around the wearer's waist.
  • a problem often encountered during use of a conventional diaper as described above is that fecal material may leak from the rear of the diaper due to activ ⁇ ity by the wearer or when the wearer sits down. The fecal material often moves through the gluteal groove (the open space between the buttocks), and in some instances may exit the diaper at the wearer's back. This situation is, of course, very undesirable because it usually necessitates additional cleaning of the wearer and, likely, cleaning of clothing and/or bedding.
  • Diapers are known in the prior art, having parts which are designed to extend along the gluteal groove.
  • the K. A. Dreier et al. U.S. patent No. 5,171 ,236 describes a "central spacer 56" which has "the advantage of reducing the amount of fecal material in the gluteal groove of the wearer".
  • the M. A. Bruemmer et al. U.S. Patent No. 5,176,672 describes a "cleft block 26", one function of which is "to aid in preventing fecal material from moving up the cleft of the baby's buttocks".
  • 5,306,266 also describes spacers 54 and 66 which may "plastically deform". While the devices described in the prior art patents may function as purported in the patents, there is a continuing need for a diaper including an improved device for blocking the movement of fecal material along the gluteal groove of the wearer.
  • a diaper constructed in accordance with this invention comprises a core of absorbent core material, a liquid pervious topsheet and a liquid impervious backsheet, the two sheets enclosing the core and being attached together.
  • the diaper when placed on a wearer includes a crotch area, a front area extending toward the wearer's navel, and a back area covering the wearer's buttocks and gluteal groove.
  • the diaper further com ⁇ prises a blocking part in the back area, the blocking part being constructed and located to block the gluteal groove and thereby retard the flow of fecal material rearwardly through the groove.
  • the blocking part conforms well to the shape of the wearer's body and therefore effectively blocks the groove.
  • Fig. 1 is a depiction of a child wearing a diaper constructed in accordance with the invention
  • Fig. 2 is a plan view showing the diaper
  • Fig. 3 is a sectional view taken on the line 3-3 of Fig. 2;
  • Fig. 4 is a view similar to Fig. 3 but showing an alternative construction of the diaper;
  • Fig. 5 is a plan view of a blocking part of the diaper shown in Figs. 1 to 4;
  • Fig. 6 is a plan view of another blocking part constructed in accordance with the invention.
  • Fig. 7 is a sectional view taken on the line 7-7 of Fig. 6;

  • Fig. 12 is a view similar to Figs. 9 and 11 but showing still another form of the invention.
  • FIGs. 13 and 14 are views showing still additional forms of the invention.
  • Fig. 15 is a sectional view taken on the line 15-15 of Fig. 14.
  • a wearer 20 (in this instance a child) is fitted with a diaper 21 which includes a front area 22 (Fig. 2), a crotch area 23 and a back area 24.
  • the crotch area 23 extends between the legs of the wearer 20
  • the front area 22 extends toward the wearer's navel
  • the rear area 24 extends over the wearer's buttocks and over the gluteal groove which separates the two buttocks.
  • the rear area 24 extends past the rearward end of the groove and to the lower region of the wearer's back.
  • the back and front borders 26 and 27 (which may be elastic) extend across the width of the diaper, and fastener tabs 28 are secured to the corners of the diaper.
  • the tabs 28 are, of course, fastened at the waist to hold the diaper on the wearer when in use.
  • the edges 29 of the crotch area 23 are preferably elastic.
  • the parts of the diaper described in this paragraph may have a conventional construction.
  • the diaper in Fig. 3 it is formed by a core 31 of a highly absorbent core material. Across the outer side of the core 31 is a backsheet 32 of a liquid impervious material (such as plastic), and across the inner side (the skin side) of the diaper is a topsheet 33 of a soft liquid pervious material.
  • the parts 31, 32 and 33 may be formed of conventional materials in common use for these purposes, such materials being disclosed, for example, in the K. A. Dreier U.S. patent No. 5,171,236. The disclosure of patent No. 5,171,236 is incorporated herein by reference.
  • the sheets 32 and 33 are sealed together and enclose the core 31, the sheets 32 and 33 also being attached to the core 31.
  • the diaper 21 further includes a blocking part 36 which is located in the back area 24.
  • the blocking part 36 When worn, the blocking part 36 is located to extend from approximately the rearward side of the wearer's anus (indicated by the dotted line 37 in Fig. 2) to a location adjacent the back border 26. Further, the part 36 is located along the lengthwise centerline of the diaper, and as a consequence, it extends along the gluteal groove of the wearer.
  • the dimensions, the shape and the compression and recovery criteria of the part 36 are such that it conforms substantially to the shape of the wearer's body and extends at least partially into the gluteal groove.
  • the part 36 blocks or at least substantially retards the flow of fecal material rearwardly through the groove and out of the backside of the diaper.
  • the blocking part 36 may be located between the topsheet 33 and the core 31 as shown in Fig. 3 and press the topsheet 33 against the wearer. Instead, it may be located on the outer side of the core 31 (between the core 31 and the backsheet 31) as shown in Fig. 4 and press the topsheet 33 plus the core 31 toward the wearer.
  • the blocking part 36 extends along the wearer's gluteal groove and it is constructed to conform to the contour of the wearer and extend into the groove. This may be accomplished, for example, by appropriately shaping the blocking part, by forming the part with compression and recovery characteristics which produce such conformity, and/or by forming the blocking part with areas or portions having different compression and recovery characteristics.
  • the blocking part 36 has a generally rectangular shape and has a substantially constant thickness. It is fastened, as by a moisture impervious adhesive, to one or more of the core 31, topsheet 33 (Fig. 3) and the backsheet 32 (Fig. 4).
  • the part 36 (and the parts 40, 46 and 49 described hereafter) may be made of a compressible and resilient material such as sponge, open or closed cell foam, nonwoven highloft materials or formed scrim structures.
  • a highloft material of poly ⁇ ester batting such as Mountain Mist #206 made by the Stearns Technical Textiles Co. of Cincinnati, Ohio may be used. This batting has an 88% compression ratio and a 94% recovery ratio.
  • combinations of the above materials with conventional absorbent materials such as airfelt or super absorbent polymers may be used.
  • a part 40 is elongated in the front-to-back direc ⁇ tion.
  • the part 40 may be made stiffer than along the two side portions 42. Consequently, when the part 40 is pressed against the wearer, the center portion 41, being stiffer and less compressible, may project into the gluteal groove whereas the side portions 42 may be pressed back from the center portion 41.
  • the center portion 41 may be made stiffer by various means such as by applying an adhesive to it, or by making the center portion 41 more dense, for example.
  • a blocking part 46 is located similarly to the part 36 but is contoured to better fit the gluteal groove.
  • the part 46 widens or flares laterally and toward its end which is adjacent the back border 26, thereby producing a narrow end 47 and a wide end 48. The amount of the widening is exaggerated in the drawings.
  • the blocking part 49 shown in Fig. 8 has both a flare as shown in Figs. 6 and 7 and a peaked shape in cross section.
  • the height of the peak 50 may also vary as illustrated in Fig. 8 (the peak 50 is preferably highest at the end which is adjacent the back border 26 but the highest point may be anywhere along the length of the blocking part).

  • the elastic strips can be elongated or stretched relative to their free lengths and relative to the folded strips. While elongated, the elastic strips can be attached to the folded strips at spaced apart locations along the length of the folded strips. When the forces causing the elongation of the elastic strips are released, the elastic strips will contract relative to the folded strips, thereby drawing the spaced apart attachment points on the folded strips together to form the pleats.

Abstract

La présente invention concerne une couche comportant une pièce permettant de bloquer le passage de la matière fécale derrière le pli fessier. La couche est constituée, d'une part d'une âme de matière absorbante recouverte d'un voile de couverture et d'un voile de support, et d'autre part, d'une partie arrière recouvrant le pli fessier. Dans sa partie arrière, la couche comporte en outre une pièce d'arrêt dont l'effet est de créer une pression dans la rainure fessière, empêchant ainsi le passage de matière fécale vers l'arrière, en passant par le pli fessier. Cette pièce d'arrêt, qui épouse la forme du pli fessier, présente des coefficients de compression et de reprise qui procurent une meilleure conformation.
