Definitions
- Absorbent artides such as infant diapers, training pants, adult incontinence products. and the like are well known. Such articles have achieved a wide acceptance due to their ability to receive and absorb Igpdy exudates.
- T ⁇ is invention pertains to a personal care artide fcr containing body exudates.
- This invention utilizes an aperture mounted in the gluteal fold of a user to minimize contact of fecal material with the skin of a user.
- the aperture transfers fecal mate ⁇ al to an exudate containment receptade formed by an exudate panel mounted on the substrate.
- body exudates of u ⁇ ne and fec3l material s ⁇ ould be received a ⁇ c contained by the absorbent article.
- leakage problems are common, especially cf fecal material.

- Exudate containment receptacle 30 ⁇ esirably has a slippery inner surface that allows exudates to enter and flow easJy throughout Accordingly, as body forces are exerted on containment receptacle 30 from differing directions, exudates aiready in the receptacle easily move about the rec ⁇ otacle as the receptacle dynamically changes shape in resoonse to such forces
- exudate containment receotacle 30 can include superabsorbe ⁇ t mate ⁇ al for example, loosely contained within, or secured to the walls forming the containment receptacle Such superabsoroent material can absorb urine passing through liquid transfer structure 28 and into containment receptacle 30 and liquids from fecal mate ⁇ al

- Exudate panel 31 can be formed of thermoplastic mate ⁇ afs such as vinyl, polypropylene and polyethylene. Exudate panel 31 preferably has a ciothlike feel, especially on its outer surface. Exudate panel 31 can also be formed from sheets of material similar to the mate ⁇ al of outer cover 50 desc ⁇ bed herein.
- Front wall 43 is secured to substrate 18, for example, by lines 52 of adhesive extending along the length of exudate pane! 31 outwardly from front edges 42. Placing adhesive on ends 54 assists in secu ⁇ ng exudate panel 31 to substrate 18, thus defining exudate containment receptacle 30. Adhesive lines 52 and adhesive placed on ends 54 of exudate panel 31 provide a liquid-tight seal for exudate containment in exudate containment receptacle 30.
- undulations 46 can expand rear wall 44 along its entire length, and front wall 43 in areas away from adhesive lines 52. Further, the in-folding of front wall 43 provides for additional volumet ⁇ c capacity in exudate containment receptacle 30
- the volumetnc capacity of receptacle 30 is greater than that set forth for the single indentation 40 in the first embodiment, and enables containment receptacle 30 to receive and retain larger quantities of body exudates.
- FIGURE 8A is a cross section view of FIGURE 5 having bodyside liner 22 no longer cut-away, and without an outer cover. Only bodyside liner 22 of substrate 18 and exudate panel 31 are shown. Outer cover 50 is not necessary where bodyside liner 22 and exudate containment receptacle 30 have enough structural strength to provide a reliable personal care article 8
- outer cover 50 can be secured to bodyside liner 22 of substrate 18 and rear wall 44 of exudate panel 31 as shown in FIGURE 8E This arrangement creates a product that appears more like a conventional personal care article 8 to the eye of a potential user.
