Abstract: The fragrance release system comprises a closure (1) with cap for closing an opening of a container, a means for sealingly closing the opening of the container for flowable or pourable products, a chamber (3) formed by a chamber base (8), a chamber casing (7) and a chamber lid, and a fragrance release device having a means for coupling the chamber with the release device detachable from the closure. The chamber has an opening, which releases the fragrance from an interior of the chamber, and is partially filled with a fragrance-containing preparation. The fragrance release system comprises a closure (1) with cap for closing an opening of a container, a means for sealingly closing the opening of the container for flowable or pourable products, a chamber (3) formed by a chamber base (8), a chamber casing (7) and a chamber lid, and a fragrance release device having a means for coupling the chamber with the release device detachable from the closure. The chamber has an opening, which releases the fragrance from an interior of the chamber, is partially filled with a fragrance-containing preparation, and is detachably fixed on the closure and the release device in form-, material- and/or friction-locked manner. The closure cap and the closure means are designed so that a delivery of product from the container is prevented upon interaction with the container opening in the closed position of the closure. The means causes a detachable fixing of the chamber with the release device. The fragrance release device and/or the chamber comprise a unit, which causes a controlled release of fragrance from the release device. The chamber is detachable by a tractive force of larger than 1N along the longitudinal axis of the closure cap and the release device. The closure cap has a dosage volume formed by a lateral surface (5) and a base in cup-like manner. The chamber is two-partly formed from a cup-shaped element and a closing plate, by which the opening of the element is closable in form-, material- and/or friction-locked manner. The element on the lateral surface has a circulating groove, which cooperates with a corresponding nib of the closing plate, so that a latching connection is formed between the closing plate and the cup-shaped element. The opening of the element is sealingly closable by the closing plate. The chamber is sealingly formed opposite to the closure cap. The closing plate is U-shapedly formed in the cross section. The closure means is formed as retaining ring with an inner-lying screw thread. The closure and/or the release device have a collar, which forms a dome-like elevation protruding from the closure. The chamber is fixable on the elevation by mounting. The volume of the chamber loaded with the fragrance is 5-100 ml. The chamber has a sealed adhesive strip for fixing the chamber at the structures outside the closure. The chamber contains active substance having fragrance, perfume carrier, coloring materials, tenside, antimicrobial active substances, germicide, fungicides, antioxidants and/or corrosion inhibitors. The active substance is a polymer material loaded with the fragrance. The polymer carrier material has a melting point or a softening point of 75-80[deg] C. The particles of the active substance have an average diameter of 3-6 mm. The weight portion of the fragrance is 30-40 wt.%. The closure has a closure element for the opening of the chamber, which reduces the delivery of the active substance from the chamber in the closed position at the surroundings and enables the delivery of the active substance from the chamber in the opened position. The closure element enables a repeated releasing and closing of the opening. An independent claim is included for a packing having a container for flowable or pourable products.
