A method and device for indicating whether a dispensable product will require refilling prior to the next scheduled service interval includes tracking the amount of use over a first interval, and calculating a frequency based from the use over the first interval. The quantity remaining is compared with the required amount, which is the product of the number of weeks in the service interval and the calculated frequency. Thus, when the quantity remaining is less that the required amount, a warning will be provided to indicate that the dispensing product should be replaced, as it will be empty before the next service interval.

A dispenser container having a retractable nozzle is proposed. The container is configured such that an air pumping part (30) is coupled and secured to an upper portion of a container body (10) by a locking cap (20), a guide cap (20) configured to be movable up and down is coupled to the outer surface of the locking cap (20) at a location outside the locking cap, and a nozzle cap (50) configured to pressurize and operate the air pumping part while being rotated and being moved up and down in conjunction with the guide cap is coupled to an upper portion of the guide cap (40) at a location outside the guide cap so that the nozzle (60) coupled to the nozzle coupling hole formed at the side of the nozzle cap is extended and retracted in response to the rotation of the nozzle cap.

A fluid dispenser assembly having a nasal fluid dispenser device (1000) with a reservoir (30) and, a dispenser head (1) assembled on the reservoir (30); a remote mobile device (2000); and an orientation sensor (113) to obtain optimal orientation of the dispenser device (1000) when actuated. The sensor determines the three-dimensional orientation of the device, including the angle (α) of the device relative to said remote mobile device. A second sensor (121) is provided for detecting when the device (1000) is actuated by the user. The remote mobile device includes an accelerometer to determine its position in three-dimensional space, in particular the angle (β) of the remote mobile device (2000) relative to the vertical.

Systems and methods for isolating and/or desiccating a portion of a drug delivery tract of a drug delivery apparatus to reduce water vapor content therein are provided. For example, there is provided a metered dose inhaler for delivering aerosolized medicament or other matter to a user. The aerosolized medicament or other matter may be discharged from a discharge passageway within the inhaler into an inhalation passageway for inhalation by a user, and the inhaler may comprise a seal member operative to selectively isolate the discharge passageway from the inhalation passageway and external environment during inactivity. The inhaler may further comprise a desiccant material arranged to withdraw moisture from the isolated discharge passageway. In other instances, desiccant material may be arranged to withdraw moisture from the discharge passageway of the inhaler without isolating the discharge passage during inactivity.

A pump for dispensing a fluid, has a pump head, a piston with a piston body, a pump chamber provided by a pump chamber part, an inlet valve and an outlet valve. The piston body is moveable relative to the pump chamber. The piston body is tube-like, providing a channel for delivering the fluid from the pump chamber via the outlet valve to an outlet opening in the pump head. The outlet valve is a valve body cooperating with a sealing rim formed by an opening in an outlet channel of the pump head. The piston body has a sealing lip for with an inner surface of the pump chamber body. The pump head is moveable relative to the piston body providing an opening stroke for the outlet valve, wherein the valve body moves axially in the opposite direction into a part of the outlet channel above the valve body.

The invention relates to a method for controlling an electrostatic atomizer for liquids, the atomizer comprising a liquid tank and a delivery device for liquid from the liquid tank, a high-voltage source and also at least one atomizer nozzle for the atomization of liquid, the at least one atomizer nozzle being connected to the high-voltage source. Here, the voltage and/or the current intensity at at least one of the atomizer nozzles are detected by sensors of control electronics and/or the voltage and/or the current intensity at the high-voltage source are detected by sensors of the control electronics.

A dispenser for pasty products which has a head, a pump, an actuator, and a container tube is provided. The pump is provided with a flexible annular lip protruding out of the pump and inserted into an initial section of a dispensing tube of the head, configured to sealingly come into contact with an initial surface of the initial section to form an upper or delivery valve.

An all-plastic emulsion pump, includes a body, threads, pressing head, main column, suction tube, plastic spring, pull rod, stopper, lock cover, first and second one-way valve devices made of plastic material. A communication port is between the plastic spring and the main column. The pull rod is in the plastic spring. The stopper is connected to the pull rod upper end. When the plastic spring is pressed, there is a gap between the pull rod and the side wall of the communication port. When the plastic spring pops up, the stopper blocks the communication port. The first one-way valve device is between the pressing head and the main column to supply the emulsion to the pressing head. The second one-way valve device is between the plastic spring and the inlet of the body to supply the emulsion from the inlet of the body into the plastic spring.

A dispenser for pasty products which has a head, a pump, an actuator, and a container tube is provided. The pump is provided with a plurality of flexible flaps protruding inwardly from a dome-shaped elastically deformable cap of the pump or from a connection portion of the pump to form a lower or suction valve.
