Abstract: A container (101) has a constant wall thickness vessel (102) with a valve (103) crimped on at a neck (104) in the vessel. The valve has a dispensing stem (105). The vessel is circularly cylindrical and formed with an groove (106) extending parallel with the length of the vessel, from a base (107) to the neck (104). When the container is lain on its sidewall (108), it will roll, changing its orientation, until the groove (106) is at the surface as shown in FIG. 7, with the groove in effect floating on the surface of the liquid, providing an indication of the actual quantity of content in the container.

Abstract: A inhalation-actuable dispensing device is provided for dispensing a metered dose of medicament in aerosol form. The device comprises a compartment (6) for receiving a metered dose aerosol container (10) having an outlet tube (12) at one end. The device has a storage chamber (13; 120) which receives a metered dose from the container. The storage chamber (13; 120) has an outlet which is closed by a valve member (44; 124) under the pressure of the dose within the storage chamber. Inhalation by a user causes a dose releasing device (34, 40, 46; 138-140) to move the valve member to an open position.
