Publication number: 20140021269Abstract: A dispenser for a volatile substance, which contains a reservoir and two control elements. The first control element exerts a control function that is dependent on the substance characteristics of the volatile substance and the material characteristics of the constituents of said first control element. However, the second control element exerts a control function that is independent of the substance characteristics of the volatile substance and the material characteristics of the constituents of said first control element. The first control element is located between the reservoir and the second control element and is permeable to at least one volatile substance. The second control element consists of a material that is impermeable to the volatile substance and contains defined material cavities. Perfumes, crop protection agents, pheromones and repellents, which can be released in a controlled manner, constitute the volatile substances.Type: ApplicationFiled: September 24, 2013Publication date: January 23, 2014Applicant: LTS LOHMANN THERAPIE-SYSTEME AGInventors: Michael ROREGER, Malgorzata Kloczko, Michael Feldhege

Publication number: 20080050433Abstract: The invention relates to a water-soluble film for releasing active substances, particularly plant protection products and plant growth promoting substances. The water-soluble film can be defined with regard to its dimensions so that the content of the active substance can be exactly pre-dosed in such a defined film section. The release of the active substance or of the active substance combination from the water-soluble film ensues in a controlled manner by the action of water. The soil, standing and flowing water, surfaces of plants and other objects make up the environment.Type: ApplicationFiled: April 19, 2005Publication date: February 28, 2008Inventors: Michael Roreger, Qian-Yi Li, Malgorzata Kloczko, Iris Schnitzler
