1. A refillable spray dispenser comprises: a bottle having a spray assembly and a compartment in fluid communication with the spray assembly;the bottle further having a bottom portion comprising: a hollow injection rod comprising a rod fill hole, a rod injection hole, and a groove along the hollow injection rod;bottom portion walls;a first seal and a second seal;a bottom opening;a portion injection hole and a portion exhaust hole provided in the bottom portion walls; anda passage extending from the portion exhaust hole to the bottom opening,wherein, when the hollow injection rod is at a resting position, the first seal seals the passage, preventing communication of gas from the compartment to the bottom opening, and the second seal seals the rod injection hole, preventing communication of liquid from the rod fill hole to the compartment,wherein, when the hollow injection rod is in an extended position and the dispenser is being refilled, the first seal allows communication of gas from the compartment, via the portion exhaust hole and the passage to the bottom opening, and the second seal allows communication of liquid from the rod fill hole, via the rod injection hole, to the compartment, andwherein said groove allows gas to bypass said first seal since the first seal grips the entire circumference of the hollow injection rod and cannot seal the groove in the extended position. 2. The refillable spray dispenser of claim 1, wherein the bottom portion further comprises a third seal situated between the portion exhaust hole and the second seal, and wherein the third seal tightly holds the hollow infection rod such as to help prevent back-flow of liquid out of the bottom portion when the hollow injection rod is in the extended position and the dispenser is being refilled. 3. The refillable spray dispenser of claim 1, wherein the portion exhaust hole is positioned between the first seal and the second seal. 4. The refillable spray dispenser of claim 1, wherein the portion exhaust hole and the second seal are positioned at a same level, and wherein the passage comprises a gap between said second seal and said bottom portion walls so as to allow gas from the compartment to bypass the second seal and thereby flow from the exhaust hole to the bottom hole when the rod is in the extended position. 5. The refillable spray dispenser of claim 1, wherein the hollow injection rod further comprises a tooth proximal to the bottom opening, and the dispenser further comprising resilient elements held on the tooth, wherein the resilient elements are configured to restore the hollow injection rod from the extended position back to the resting position. 6. The refillable spray dispenser of claim 1, further comprising an endcap engaged with the bottom portion walls, the endcap being capable of supporting the hollow injection rod. 7. The refillable spray dispenser of claim 1, further comprising a third seal held in the bottom portion under the hollow injection rod, wherein the third seal allowing to sealingly and fluidly couple a filling stem of a fluid bottle or a fluid-stem adaptor thereto. 8. The refillable spray dispenser of claim 1, wherein the first seal has a circumference comprising grooves. 9. The refillable spray dispenser of claim 1, further comprising a tube extending from the compartment adjacent the top opening to adjacent the portion exhaust hole, the tube thereby allowing exhaust of gas from the dispenser and essentially preventing exhaust of liquid from the dispenser. 10. The refillable spray dispenser of claim 1, further comprising a gas-permeable gasket configured to be in fluid communication with the portion exhaust hole when the hollow injection rod is in the extended position, allowing slow and controlled release of gas from the dispenser. 11. The refillable spray dispenser of claim 1, wherein the bottle has rigid walls configured to allow forming a negative air pressure in the compartment, wherein the negative pressure thereby facilitates filling of the compartment with fluid. 12. The refillable spray dispenser of claim 11, wherein there is essentially no take up of air in the compartment in compensation for the liquid being dispensed. 13. The refillable spray dispenser of claim 1, wherein the spray assembly comprises a vent hole that is arranged to compensate for dispensed liquid with air. 14. The refillable spray dispenser according to claim 13, wherein the spray assembly is mounted on top opening in a storage position in which the vent hole is closed off, wherein said spray assembly is movable with respect to the compartment in a dispensing position which said vent hole is free to enable air to be taken up. 15. The refillable spray dispenser of claim 1, wherein the spray assembly comprises a dispensing pump actuatable by means of a push button, wherein the push button is mounted on a nozzle of the pump, wherein the push button comprises an upper region enabling exertion of finger pressure on said push button to be able to move said button axially, thereby actuating the pump, wherein the pump comprises: a body equipped with a plunger tube disposed in the bottle, wherein said tube is equipped with a valve for admitting the liquid into the pump;a piston mounted around said nozzle to delimit a metering chamber in the body;an extender within the body; anda spring in abutment with a bottom of the extender,wherein return of the push button over its suction travel is effected by a spring in said pump. 16. The dispenser of claim 1, wherein the sealing of the rod injection hole is due to the hollow injection rod fitting tightly within the second seal. 17. A kit comprising the refillable spray dispenser of claim 1 and at least one adaptor, wherein the adaptor is configured to allow sealingly and fluidly coupling a non-refillable dispenser with the hollow injection rod of the refillable dispenser. 18. The kit of claim 17, wherein the non-refillable dispenser is a liquid dispenser or an aerosol. 19. A kit comprising the refillable dispenser of claim 1 and a non-refillable dispenser, the refillable dispenser and the non-refillable dispenser sealingly and fluidly coupleable thereto.
