    Abstract

    The freshener revealed here is used for perfuming and freshening various objects and spaces. It comprises several components, one of which is in the form of a capsule which contains a fragrance. The capsule may be a microcapsule or a nanocapsule. It is applied by spraying directly on the fabric or surface. A pleasant, floral fragrance smells from the first application, however, the specificity of this freshener is noticeable after it is dried on the treated surface. After application by spraying and the time of drying, in physical contact with the treated surface the capsules break and release the fragrance into the space. This freshener is used on all types of textiles, leather, artificial leather, but also on hard and less absorbent surfaces. Mechanic force/friction (sitting, walking and the like) cause the breaking of the fragrant capsules that remain on the fibres, thereby obtaining the additional boost of fragrance. By its very nature, the product is completely safe to use, it does not comprise hazardous components. These capsules provide longer lasting freshness because the fragrance is protected as long as the capsules are intact. Only after application of a force, by breaking capsules, pleasant fragrance is released.

    11. Freshener for spaces and objects, as claimed in claim 1, characterized in that the preservative is 1,2-benzisothiazol-3(2H)-one and 2-Methyl-2H-isothiazol-3-one and N-(3-aminopropyl)-N-dodecylpropane-1,3-di amine.

    12. Freshener for spaces and objects, as claimed in claim 1, characterized in that the capsules have such characteristics that after the application of the force onto the capsule, the membrane of the fragrance capsule breaks and the fragrance is released at once.

    13. Freshener for spaces and objects, as claimed in claim 1, characterized in that the capsules have such characteristics that after the application of the force onto the capsule, the membrane of the fragrance capsule cracks and, after releasing the initial noticeable amount of the fragrance, it continues to release the fragrance over a certain period of time up to several months.

    14. Freshener for spaces and objects, as claimed in claim 1, characterized in that the capsules have such characteristics that after the capsule is activated by touch, the capsule has a better/stronger instantaneous release of the fragrance, but also the effect of prolonged action/fragrance release.

    15. Freshener for spaces and objects, as claimed in claim 1, characterized in that the capsules have such characteristics that after the application of the force onto the capsule, the membrane of the fragrance capsule cracks and, after releasing the initial noticeable amount of the fragrance, it continues to release the fragrance over a certain period of time up to several months and/or that after the application of the force onto the capsule, the membrane of the fragrance capsule breaks and the fragrance is released at once and/or that after the capsule is activated by touch, the capsule has a better/stronger instantaneous release of the fragrance, but also the effect of prolonged action/fragrance release.

    16. Freshener for spaces and objects, as claimed in claim 1, characterized in that it is used for freshening of the fabrics and textiles.

    17. A method of using the freshener for spaces and objects, of claim 1, characterized in that it is applied by spraying directly onto the surface or the fabric.

    18. A method of using the freshener for spaces and objects, of claim 1, characterized in that it is applied by sprinkling onto the surface.

    Description

    DETAILED DESCRIPTION OF AT LEAST ONE WAY OF CARRYING OUT THE INVENTION

    [0014] One of the possible methods of preparation of this freshener for spaces and objects is to prepare a fragrant blend comprising 50-100 parts by mass of demineralised water, 0-10 parts by mass of thickener or viscosity modifier, 0-10 parts by mass of sodium chloride, 0-10 parts by mass of nano-encapsulated fragrance and 0-1 parts by mass of preservative.

    [0015] Afterwards with such a mixture, by nanoencapsulation method, the nano-capsules are made. The resulting mixture i.e. the nanocapsules are mixed with a particular medium and filled into pressurized or non-pressurized vials.

    [0016] The method of using the subject freshener for spaces and objects is to apply it by spraying directly onto the surface or the fabric. It takes some time for the applied freshener to dry. A fragrance occurs when the nanocapsules break, usually due to pressure or friction which they are exposed to, for example, by walking on the surface comprising nanocapsules, sitting on the chair on the surface of which are the nanocapsules, wiping with the towel with nanocapsules, etc.

    [0017] This freshener may also be applied by coating, sprinkling or immersion.

    [0018] After the drying time and water evaporation, a thin layer of nanocapsules with fragrance is formed on the treated surface. Typical applications are in transport and carriage of passengers and goods, tourism, foodservice sector and hospitality industries, public institutions and public facilities, health facilities, sport facilities, wherein the freshener is applied onto the carpets, upholstered furniture and seats, seats and floors in vehicles for passenger transport and transporting goods, on the bed linen, napkins, tablecloths, curtains, towels, upholstery, and clothing.

    [0019] A commonly used preservative is either 5-chloro-2-methyl-4-isothiazolin-3-one and 2-methyl-4-isothiazolin-3-one and benzyl alcohol or 1,2-benzisothiazol-3 (2H)-one and 3(2H)-Isothiazolone, 2-Methyl- or 1,2-benzisothiazol-3(2H)-one, and 2-methylisothiazol-3(2H)-one or 1,3-Bis (hydroxymethyl)-5,5-dimethylimidazolidine-2,4-dione and Formaldehyde or 1,2-benzisothiazol-3(2H)-one and 2-Methyl-2H-isothiazol-3-one and N-(3-Aminopropyl)-N-dodecylpropane-1,3 diamine.

    [0020] In certain embodiments, this freshener for spaces and objects comprises capsules of such characteristics that after the application of the force onto the capsule, the membrane of the fragrance capsule breaks and the fragrance is released at once. In another embodiment, this freshener comprises capsules of such characteristics that after the application of the force onto the capsule, the membrane of the fragrance capsule cracks and, after releasing the initial noticeable amount of the fragrance, it continues to release the fragrance over a certain period of time up to several months. In further embodiment, this freshener for spaces and objects comprises capsules of such characteristics that after the activation of the capsule by touch, the capsule has a better and stronger instantaneous release of the fragrance, but also the effect of prolonged action/fragrance release.

    [0021] It is possible that in one embodiment all three types of capsules are used, so that this freshener for spaces and objects comprises capsules of such characteristics that after the application of force on the capsule, the membrane of the fragrance capsule cracks and, after releasing the initial noticeable amount of the fragrance, it continues to release fragrance over a certain period of time up to several months and/or after the application of the force onto the capsule, the membrane of the fragrance capsule breaks and the fragrance is released at once and/or after the activation of the capsule by touch, the capsule has a better and stronger instantaneous release of the fragrance, but also the effect of prolonged action/fragrance release.

    [0022] In one embodiment, instead of the fragrance, the capsule may comprise odour neutralizer, i.e. antiodour, whose function would be, instead of scenting the objects, to neutralize the smell, i.e. the bad odours.
