A container for liquid or pasty substances or powders, suspensions or liposomial preparations, for pharmaceuticals, diagnostics, cosmetics or similar, enclosed in a plate 6 of plastic material, comprising two semi-containers 2 with bodies 4 and necks 3, close together and parallel. Pre-cut lines 9-10; 109-110 are provided and at least some of these concern the topi of the said necks 3, in such a way as making a separation along these pre-cut lines causes the selective opening of a said semi-container 2, or of both of them, and therefore the dispensing of a half dose or of the entire dose of the product in the container 1.
A set 20 of containers 1 is also described, comprising a plurality of containers 1 joined between themselves along lines of breakable joints 21 and that allow their separation at the moment of use.
