    摘要： A pair of similarly sized sheets of a pliant, heat resistant material such as cloth are stitched together in face to face relation. A quantity of unbound particulate material such as metal shavings or vegetable material is dispersed between the sheets. Stitching between the intermediate portions of the sheets defines a plurality of pockets so that the particulate material remains substantially dispersed over the area of the sheets. The particulate material preferably has sufficient thermal inertia so that the food warmer may be placed in an oven to heat the particulate material and thereafter wrapped about a portion of food to keep it warm during a meal.

    摘要： The present invention relates to a protective mattress sheet which is capable of being washed frequently.To this end, the sheet consists of a layer (6) of waterproof fibers which retain liquids by capillary action contained between two fabric layers (4) and (5), the upper one of which is a wide-meshed fabric and the lower one of which is waterproofed. The protective sheet is bordered by a bias (13). It may also comprise two small lateral grooves, each formed by folding back an edge (14), the small part which is folded back being secured by stitches (18). An absorbent material (17) may be easily introduced into the grooves.The present invention may be used both for hospital beds and in the hotel industry.
