Abstract (en)
[origin: EP1092642A1] Container (1) has a first chamber (11) for a product to be dispensed e.g. via a manually-operated pump (5), and a second chamber (12) holding a substance which maintains a pressure on the product to ensure that a constant volume of the product is dispensed. The second chamber is connected to the first via a siphon (30) which allows through a portion of the compression substance each time the dispenser is used.
