Abstract: A patch device that includes a backing layer which is a barrier to at least a fragrance, a reservoir layer, which is attached to the backing layer and serves for holding a volume of one or more fragrances, and a cover layer for covering the reservoir layer when filled with fragrance. The cover layer is permeable to vapor from at least one fragrance, which cover layer in a first position of the patch device, in which the reservoir layer is free of fragrance, is situated at least partly offset or dislocated from the reservoir layer, and which cover layer in a second position of use, in which the volume of one or more fragrances has been delivered to the reservoir layer, covers the reservoir layer. Support sheets, which support the backing layer, and a flap part of the cover layer, serve as a tool for applying the flap part into covering relationship to cover or encapsulate the reservoir layer.
