Abstract: A paperboard carton for storing and dispensing a roll of web material, such as plastic film, foil, wax paper, etc. has a plastic (e.g., polystyrene) cutting blade that is adhered either to an inside surface of the front wall of the paperboard carton, or to an inside surface of the bottom wall of the paperboard carton. The polystyrene cutting blade preferably has a thickness of about 20/1000 of an inch, and preferably contains aggressive teeth at the ends of its serrated edge to help initiate tearing of the web material. The aggressive teeth are larger in size than the remaining teeth of the serrated edge. A slot is die-cut through the paperboard carton blank at the appropriate location in order to allow the serrated edge of the cutting blade to protrude through the slot and expose the teeth in a location suitable for tearing the web material.  Use of the plastic or polystyrene cutting blade allows for increased production rates without compromising performance.

The waist and femoral regions of the pants are provided with sealing rings for sealing of the space inside the pants during waste handling cycles of the patient care, and unsealing when this cycle is completed. The pants are provided with vibrators for creating a scrubbing action during the washing cycle. Air supply into the pants during washing is added to enhance scrubbing. During rest periods, the vibrators and air flow creates an aeration for drying and massage, enhancing the patient's well-being. The inner surface of the pants is fitted with inflated spaces creating canals for air flow next to the skin for airflow enhancement and prevention of bed sores, the space around the pubic and anal regions being shaped for easy and rapid removal of excretory materials.  Sensors are located in the pants for remote control of all materials handling functions in the patient care process. Optionally, the pants are provided with manually sealed fasteners to be operated by the care giver. The mattress is provided with inflatable chambers that facilitate positioning of the patient's body and creation of a hollow space for bath water, thereby facilitating in-bed bathing of the entire body.
