Containers for incrementally dispensing pressurized contents are described. The containers comprise a vessel suited to contain pressurized contents, a port integral with the vessel and through which pressurized contents contained in the vessel can be released from the vessel, preferably incrementally in approximately equal amounts, and a measuring device disposed in the vessel. The measuring device senses ambient conditions in the vessel and, directly or with other components, indicates, for example, the amount of pressurized contents remaining in the vessel and displaying it to an observer; methods for comparing the amount of contents actually released from the vessel compared to a theoretical constant; and methods for time logging (alone or in conjunction with the logging of other data) the actuation of the dispensing valve for comparison to a prescribed method. Devices (including metered dose inhalers) for incrementally dispensing pressurized contents from such containers are also described.
