发明名称 PREPARATION OF DRUG-CONTAINING RETICULATED BODY
摘要 PURPOSE:To prevent the scattering or the consumption of a drug, by temporarily laminating one of the drug impermeable sheets of the outermost layers of a laminate to a drug-containing sheet in a releasable manner to form a laminate and applying a large number of discontinuous breaks to said laminate in a zigzag pattern and stretching the same in the direction right-angled to the direction of the breaks. CONSTITUTION:A drug-containing sheet 2, which is composed of a resin prepared by impregnating a drug impregnating resin such as an ethylene/vinyl acetate copolymer with a drug such as perfume or a resin prepared by further diluting the drug impregnated resin with a polyolefinic resin, is delivered and drug impermeable sheets 3, 3' composed of a saponified ethylene/vinyl acetate copolymer are laminated to said sheet 2 and the obtained laminate is uniaxially stretched by stretching or rolling rolls 5, 5'. Thereafter, a large number of discontinuous breaks 8 are applied to the laminate in a zigzag pattern in a flow direction by a fiber dividing jig 6 and the laminate is expanded in the direction (lateral direction) A-A' right-angled to the break direction on a belt conveyor 7 to obtain a drug-containing reticulated body 1.
