Abstract

Method for generating pressure in a spray can and the like, whereby at least two products (8-9) are brought into contact with each other such, that, by doing so, a gas is produced and, thereby, a gas pressure is created, characterized in that the products (8-9) are brought together via a passage (12), whereby the flow rate via this passage (12) is controlled by means of a movable element (18-50-56-68) which, in its turn, is controlled by the gas pressure prevailing around the device.
