A container has a product chamber for containing a product. The product chamber has a product opening that opens into the exterior. A closure member is releasably mounted on the product opening. The container further includes an additive chamber for containing an additive, and a pressure valve that connects the additive chamber and the product chamber with each other. The pressure valve has a closed position when the pressure inside the product chamber is higher than the pressure inside the additive chamber, and an open position for discharging additive from the additive chamber into the product chamber when the pressure inside the product chamber is lower than the pressure inside the additive chamber. The pressure inside the product chamber is higher than the ambient pressure and the pressure inside the additive chamber is both lower than the pressure inside the product chamber and higher than the ambient pressure.

The container according to claim 1, wherein the additive chamber is filled with an additive leaving clear a head space comprising a pressurized gas at the pressure (p2) that is both lower than the pressure (p1) inside the product chamber and higher than the ambient pressure (patm). 6. The container according to claim 5, wherein the additive comprises a liquid, and wherein the additive chamber comprises a discharge tube that extends from a discharge opening, which discharge tube has an passage opening that is submerged into the liquid additive. 7. The container according to claim 6, wherein the additive chamber comprises a holder defining an interior that is in communication with the interior of the discharge tube via the passage opening. 8. The container according to claim 7, wherein a head space comprises a head space portion within the holder and a head space portion within the discharge tube, which head space portions are separated from each other by the liquid additive and the discharge tube wall. 9. The container according to claim 1, wherein the container comprises a base and a circumferential wall that extends from the base, wherein the product opening is provided at the end of circumferential wall facing away from the base, wherein the additive chamber is attached to the base of the container. 10. The container according to claim 9, wherein the base of the container comprises a cavity, and wherein the additive chamber is attached from the outside into the cavity. 11. The container according to claim 1, wherein the additive chamber is attached to the closure member that is releasably mounted on the product opening. 12. The container according to claim 11, wherein the access opening is provided in the closure member. 13. The container according to claim 1, wherein the additive chamber comprises an accommodating opening for accommodating the pressure valve, which accommodating opening is defined by a circumferential edge, and wherein the pressure valve comprises a flexible material, and is provided with an end flange and a circumferential sealing skirt at a distance from the end flange, and wherein said circumferential edge of the accommodating opening is clamped between the end flange and the sealing skirt. 14. The container according to claim 13, wherein the cavity comprises a further accommodating opening for accommodating the pressure valve, which further accommodating opening is defined by a further circumferential edge, and is aligned with the accommodating opening of the additive chamber, and wherein the circumferential edges of both accommodating openings are clamped between the end flange and the sealing skirt. 15. The container according to claim 1, wherein the pressure valve is a one way valve. 16. The container according to claim 1, wherein the additive comprises vitamins. 17. The container according to claim 1, wherein the additive comprises at least one of proteins, peptides, carotenoids, anti-oxidant, flavourants. 18. The container according to claim 1, wherein the product and the additive after mixing thereof comprise a farmaceutical composition, in particular a medicament. 19. The container according to claim 1, wherein the product and the additive after mixing thereof comprise a cosmetic composition. 20.
