PURPOSE:To preserve food well as well as to remove an offensive smell by dividing a mat of a certain size into small squares of a prescribed size, placing an equal amount of specific agents in each of the squares and sealing them with heat. CONSTITUTION:A non-woven fabric of a certain size is previously divided into small squares of 3-10cm. An equal amount of specific agents, which are effective for preserving food, e.g., deodorizing, sterilizing or maintaining the freshness, is placed on the center of each of the squares, and another non-woven fabric 2 is piled on the first layer of the fabric. All lines which define the squares are then sealed with a heat-sealing device. The agents are equally divided in the squares and is not gathered on one side, thus keeping the thickness of the mat of non-woven fabric equal. |
