  • Patent number: 6684440
    Abstract: A vapor-venting containment bag having at least three flexible side walls and a VVE rating of at least about 40 and less than about 90, as measured in the Vapor Venting Evaluation Test. When the bag is in its closed configuration a three dimensional interior void space is formed whereby the bag resists collapsing. Also, a fabric cleaning and refreshment process that is conducted in a hot air clothes dryer using the vapor-releasing containment bag. The bag is constructed using heat resistant polymers, such as nylon. The bag retains its integrity and can be re-used in subsequent dry cleaning operations. Vapor is vented from the bag during use, thereby minimizing wrinkling in the clothes being cleaned and removing malodors therefrom.

  • Patent number: 6683229
    Abstract: The present invention provides an absorbent article such as a diaper, a training pant, an adult incontinence article, a bed mat, or the like which is capable of evenly storing urine in a first storage region and in a second storage region. In particular, the fraction of the amount of liquid stored in the first storage region to the amount of liquid stored in the second storage region remains relatively unchanged over a wide range of loadings of the article. The present invention further provides a process for handling urine in the absorbent article which comprises a step of storing liquid in a first storage region and of storing, liquid in a second storage region such that the ratio of the amount of liquid stored in the first storage region to the amount of liquid stored in the second storage region remains relatively constant over a wide range of loadings of the article.

  • Patent number: 6627787
    Abstract: An absorbent article containing a liquid pervious topsheet coated with a lotion composition is disclosed. The lotion composition reduces the adherence of BM to the skin of the wearer, thereby improving the ease of BM clean up. The lotion composition comprises a plastic or fluid emollient such as mineral oil or petrolatum, an immobilizing agent such as a fatty alcohol or paraffin wax to immobilize the emollient on the surface of the absorbent article topsheet, and optionally a hydrophilic surfactant to improve wettability of the coated topsheet. Because the emollient is substantially immobilized on the surface of the topsheet, less lotion is required to impart the desired therapeutic or protective lotion coating benefits.
