Container (4), made from glass, plastic or metal, consists of two reservoirs holding different products to be mixed prior to use or consumption, the second reservoir being in the form of a cartridge fitting over a plunger (11) projecting from the first (15) and closing its two ends. A cap (27) with an internal thread (26) engages with an external thread (25) on the cartridge sleeve, and has an inner plug (33) and thrust member (38) to apply an effort to the plunger for opening the cartridge for the products to be mixed. Prior to use the cap is fitted with a tamper-proof ring (31).
