  • Patent number: 5026363
    Abstract: A diaper primarily for use by a baby or toddler, and also usable by a person as required, is provided. The diaper has a hour glass, bikini bottom shape with front, and center and back portions. The diaper has a multi-layer construction including a first exterior bottom layer and a second middle layer and a third interior top layer. The interior and exterior layers are each about 1 mil in thickness and the middle layer is about several mils in thickness. The interior layer is a thin, moisture permeable biodegradable material. The middle layer is a thin, high moisture absorbing breathable, biodegradable material. The exterior layer is a thin, low density breathable, hydrophobic layer. Thus, this diaper is easily flushable down a toilet. Also, the diaper has separation means which can include a tear string for tearing the exterior layer for separating the diaper into two parts for flushing separate pieces thereof together in a single flush.

  • Patent number: 4723953
    Abstract: An absorbent pad is provided which includes an absorbent layer which serves as a reservoir for liquid and has a liquid impervious barrier over one surface thereof. The liquid is applied to the opposite surface of the barrier and is conducted by means of wicking material to the sides of the barrier and into the absorbent layer. This arrangement enhances drying of the upper surface of the barrier and wicking material shortly after application of the liquid. A hydrophobic porus of open weave material can be provided over the wicking material to protect it and to provide a surface through which the liquid can reach the wicking material and the barrier sheet. The barrier sheet can have multiple channels formed in the liquid receiving surface thereof to disperse the liquid toward the edges thereof.
