Abstract
A container comprises a bottle for a liquid product and having at the end of its neck a leakproof envelope enclosing an additional product to be stored separately from the liquid in the bottle. A cap on the neck includes a slidable push button carrying a perforator to open the envelope in a central region of the envelope to allow the additional product to mix with the liquid and then to be discharged through an eccentric duct in the cap rather than having to pass through the center of the cap where the perforator is positioned.
