摘要

Preparation of prolonged release ring, and method for producing a preparation of prolonged release cancelled.It is provided with a preparation of prolonged release ring to be used for the opening of a central portion.The preparation having a sufficient strength to prevent and cleavage in a final portion is welded.More specifically,It is provided with a preparation of prolonged release comprising at least two annular tubes of polymer having both ends sealed and integrated by the welding pressure at least a tube pOlu00edmero and at least a polymer rod having ends sealed and integrated by the welding pressure.And a liquid of sex pheromone liquid contained by at least one of the tubes or tube; in an annulus can be formed by pulling the tubes or tube and the rod separated from one another in aThe central portion between them.The central portion has not been welded to pressure; and an angle between a line connecting respective centers of the diameters of the welded pipes with each other or the tube and the rod welded with the otherAnd the direction of application of the pressure snedo from 0 to 45 198 ;.
