Abstract: The present disclosure includes a spray bottle assembly (100) which provides separate compartments for containing two or more constituents of a formulation, thereby, preventing premixing of the constituents before the first use, hence, increasing shelf life in a hassle-free way. The spray bottle assembly (100) comprises a spray head (200) for discharging the constituents of a formulation stored in the spray bottle assembly (100), a container bottle (300) for storing a passive constituent of the formulation; a storage receptacle (400) coupled with the container bottle (300), wherein said storage receptacle (400) facilitates the storage of an active constituent of the formulation isolated from the passive constituent; and a dispensing means (500) integrated with the storage receptacle (400).
