Pheromone dispenser

Abstract

The present invention relates to a pheromone dispenser, filled with pheromone or a pheromone-comprising liquid and comprising (a) a deep-drawn plastic film made of a thermoplastic film material and featuring at least one dish-shaped zone for receiving a pheromone, and a planar plastic film made of a thermoplastic film material and which is connected with the deep-drawn plastic film, the planar plastic film together with the at least one dish-shaped zone of the deep-drawn plastic film forming a durably sealed chamber which comprises the pheromone or the pheromone-comprising liquid, and (c) a recess in the zone of the interconnected plastic films, the planar plastic film being permeable to the pheromone. The invention also relates to a process for producing such a pheromone dispenser.

         17 . A dispenser for pheromones, comprising
 (a) a deep-drawn plastic film made of a thermoplastic film material and featuring at least one zone configured to form a chamber for receiving a pheromone or a pheromone-comprising liquid, and   (b) a planar plastic film made of a thermoplastic film material, wherein the planar plastic film is connected with the deep-drawn plastic film such that the planar plastic film together with the at least one zone of the deep-drawn plastic film forms a durably sealed chamber for receiving the pheromone or the pheromone-comprising liquid;   wherein the at least one zone comprises a recess where the planar plastic film is permeable to the pheromone or pheromone-comprising liquid.   
     
     
         18 . The dispenser according to  claim 17 , wherein the at least one zone is configured to form a chamber having a depth in the range of from 0.3 mm to 5 mm. 
     
     
         19 . The dispenser of  claim 17 , wherein the at least one zone is configured to form a chamber featuring at least one depression in a bottom of the chamber. 
     
     
         20 . The dispenser of  claim 17 , wherein the at least one zone comprises at least two part-zones that are connected to each other and that are arranged on either side of the recess. 
     
     
         21 . The dispenser of  claim 17 , wherein the dispenser features a notch that connects the recess to an edge of the dispenser. 
     
     
         22 . The dispenser of  claim 17 , wherein the at least one zone has an area in the range of from 2.5 cm 2  to 25 cm 2 . 
     
     
         23 . The dispenser of  claim 17 , wherein the deep-drawn plastic film is permeable to the pheromone. 
     
     
         24 . The dispenser of  claim 17 , wherein the film material of the deep-drawn plastic film is a homo- or copolymer of ethylene. 
     
     
         25 . The dispenser of  claim 17 , wherein the film material of the planar plastic film is a homo- or copolymer of ethylene. 
     
     
         26 . The dispenser of  claim 17 , wherein the planar plastic film is connected by a seal to the deep-drawn plastic film along edges of the at least one zone. 
     
     
         27 . The dispenser of  claim 17 , wherein the deep-drawn plastic film has a thickness in the range of from 0.05 mm to 0.5 mm. 
     
     
         28 . The dispenser of  claim 17 , wherein the planar plastic film has a thickness in the range of from 0.02 mm to 0.5 mm. 
     
     
         29 . The dispenser of  claim 17 , wherein the pheromone comprises at least one active substance which is selected from the group consisting of unsaturated aliphatic alcohols having 6 to 30 carbon atoms and their acetates. 
     
     
         30 . The dispenser of  claim 29 , wherein the at least one active substance is selected from the group consisting of Z9-dodecenyl acetate, E7,Z9-dodecadienyl acetate, E8,E10-dodecadienol and Z8-dodecenyl acetate, and mixtures thereof. 
     
     
         31 . A process for manufacturing the dispenser of  claim 17 , comprising:
 i) providing a deep-drawn plastic film made of a thermoplastic film material which features at least one zone configured to form a chamber for receiving a pheromone or a pheromone-comprising liquid, the at least one zone including a recess;   ii) providing a planar plastic film;   iii) filling the at least one zone with a pheromone or a pheromone-comprising liquid, and   iv) sealing the at least one zone by connecting the planar plastic film with the deep-drawn plastic film.   
     
     
         32 . The process according to  claim 31 , wherein said sealing comprises welding the planar plastic film to the deep-drawn plastic film along edges of the at least one zone to form a seal.
