A container apparatus for introducing a metered quantity of a product into a vessel such as a mixing and diluting tank without includes a capsule which is in two parts joined together by screwing and which is integral with a clamping collar screwed onto a neck (2) of the vessel. A first one of the parts of the capsule rotates together with the clamping collar during the screwing, whereas the second part is immobilized in terms of rotation relative to the vessel, and the screw pitches are such that the screwing of the clamping collar onto the neck causes the separation of the two parts the capsule and opens slots in the second part so that the product contained in the capsule can flow therethrough.
