Abstract

The present invention relates to a multi-component fragrance dispensing apparatus comprising at least an aqueous based composition and a volatile solvent based composition, wherein the apparatus comprises two separate containers, two separate non-spray dispensers, and one exit orifice therein. Methods of using the apparatus for providing a longer lasting fragrance is also encompassed by the present invention.

Claims

1. A portable multi-fragrance compositional dispensing system comprising at least an aqueous based composition and a volatile solvent based composition, wherein the system comprises at least two separate containers, wherein:

(a) a first container that contains the aqueous based composition, and a first dispenser operably connected to the first container and incorporating a first exit orifice, wherein the first dispenser is in fluid communication with the contained aqueous based composition and is a spray dispenser or a non-spray dispenser, and wherein the aqueous based composition comprises from about 0.1 wt % to about 95 wt % of water and from about 0.01 wt % to about 50 wt % of a plurality of microcapsules, wherein the wt % is by weight of the total aqueous based composition; and

(b) a second container that contains the volatile solvent based composition, and a second dispenser operably connected to the second container and incorporating a second exit orifice, wherein the second dispenser is in fluid communication with the contained volatile solvent based composition and is a spray dispenser or a non-spray dispenser, and wherein the volatile solvent based composition comprises from about 0.01 wt % to about 98 wt % of a volatile solvent and from about 0.01 wt % to about 30 wt % of a first fragrance material, wherein the wt % is by weight of the total volatile solvent based composition.

2. The portable multi-fragrance compositional dispensing system according to claim 1, wherein:

(i) the first dispenser is a spray dispenser and the second dispenser is a non-spray dispenser;

or

(ii) the first dispenser is a non-spray dispenser and the second dispenser is a spray dispenser;

or

(iii) the first dispenser is a non-spray dispenser and the second dispenser is a non-spray dispenser.

3. The portable multi-fragrance compositional dispensing system according to claim 1, with the proviso that both the first dispenser and the second dispenser cannot be spray dispensers.

4. The multi-component fragrance dispensing apparatus according to claim 1, wherein each of the spray dispensers, if present, is independently selected from:

a propellant-driven dispenser;

a mechanical spray finger-operated piston pump dispenser;

a trigger-actuated piston-pump dispenser;

other mechanical or electromechanical pump systems;
