A counter for counting delivered doses from a spray dispenser of a type having a main body holding a fluid substance to be dispensed and a cap with a pump and nozzle mounted on the main body, the counter including: a counter body having an upper recess for receiving the main body; a button in an arcuate lower depression on the counter body for actuation by a person's thumb when a dose is dispensed; a display on the counter body for displaying a number of doses dispensed from the main body; a circuit which changes the number of doses display each time that the button is depressed; a set button for setting a starting number which is displayed on the display, corresponding to a predetermined number of doses remaining in the spray dispenser; and a sound generator which generates an audible sound upon each depression of the button.

In a dispenser, particularly an atomizer, which is used for flowable substances, particularly pharmaceuticals, use is made of a pump, which must be actuated one or more times for priming purposes. Its discharge nozzle (14) is covered by a protective cap (38), which is suitable to collect and store the medium, which is discharged during the priming strokes and before the start of the useful strokes. During the priming strokes the protective cap (38) is secured on the dispenser (11). This is brought about in that a locking (40) for the protective cap is only released when the priming strokes have been performed. This can take place by electrical actuation or by material change under the influence of the medium to be discharged. According to a variant the protective cap is not itself locked, but an actuation locking takes place if the protective cap has not been fitted for the priming strokes.

Dosing device. A dosing device having a body, as well as an actuating element mounted in non-rotatable, liftable manner on the body, as well as with a counting device for the actuating strokes, which has a rotary counting ring forcibly coupled as a function of a lifting movement of the actuating element, and with at least one locking means for blocking the actuating element following a predetermined number of actuating strokes is known. According to the invention at least one locking means is associated with the counting ring in such a way that the latter can perform more than a complete revolution before the actuating element is blocked. Use for dosing atomizable media.

A miniaturised device for producing high pressure in a fluid imposes stringent requirements on the manufacturing process. The device according to the invention consists of a hollow piston displaceably mounted in a cylinder and a valve member which is guided by the hollow piston and mounted so as to be axially movable relative to the hollow piston. The valve member is arranged at one end of the hollow piston inside or immediately in front of the end of the hollow piston. The device is used in a mechanically operated high pressure atomiser. This consists of a two part housing which comprises a pump housing with nozzle, a blocking mechanism, a spring housing with spring, a non-pressurised storage container for the fluid and a mechanical counter integrated in the spring housing. The valve operates without any auxiliary force, closes very rapidly and is sealed tight against high pressure. The atomiser is safe and simple to operate and environmentally friendly. The fluid is metered extremely accurately. The atomiser is used, for example, to produce an inhalable aerosol of a liquid medicament without the use of propellant gas, at 320 bar, for example.

A liquid dosage dispenser includes a bottle and a dispenser apparatus supported on the bottle having a housing extending into the bottle and a plunger device extending into the housing for longitudinal movement therein. The housing includes an opening through which liquid in the bottle can be drawn into the housing, with one of the housing and plunger device including a stop system of predetermined configuration and the other of the housing and plunger device including a follower for contacting the stop system. The plunger is rotatable with respect to the housing to align the follower with a desired portion of the stop system, with the follower and stop system, when aligned, allowing the plunger to be moved longitudinally along the housing until the follower contacts the stop system to draw a predetermined amount of liquid through the opening into the housing. The dispenser is removable from the bottle to allow the predetermined amount of liquid to be dispensed through the opening.

A manually operable discharge apparatus (1) has a counting or determination device (20) to be mounted as a separate component on the discharge unit (2) and which is operated stepwise by the removal or fitting of a protective cap (23). Thus, existing discharge apparatuses (1) can be easily equipped with randomly operating determination devices (20).
