摘要：
A delivery system for continuous release of fragrances, repellents, attractants, and the like is disclosed. The substance to be released is comprised in a sheetlike polymer matrix. By virtue of the fact that this polymer matrix is in wound form, the substance to be released can be released from the delivery system continuously and over a relatively long time period.
