A counting mechanism (100) for a dispenser comprising: a first and a second housing part (110, 120) that are rotatable relative to each other; and a counting ring (130) disposed between the housing parts. The first housing part has a protrusion (111) which abuts the counting ring, holding a portion of the counting ring in contact with the second housing part. The relative rotation of the housing parts causes the protrusion to slide against the surface of the counting ring to drive a rolling movement of the counting ring around the circumference of the second housing part, such that a predefined rotation of the housing parts produces an incremental rotational displacement between the counting ring and second housing part to record a count. The counting mechanism provides a large gear reduction ratio in a compact form which is straightforward to manufacture and provides an accurate and reliable record of counts.

Disclosed is a ratchet mechanism having ratchet ring and a chassis. The ratchet ring is rotatable about an axis relative to the chassis, with a general direction of rotation determined by teeth of the ratchet mechanism. The ratchet ring has a first set of teeth arranged regularly around the ratchet ring and protruding in a first axial direction from the ratchet ring and a second set of teeth arranged regularly around the ratchet ring and protruding in a second opposite axial direction from the ratchet ring. The chassis has a third set of teeth arranged regularly and protruding in the second axial direction and generally opposed to the first set of teeth, and a fourth set of teeth arranged regularly and protruding in the first axial direction and generally opposed to the second set of teeth.

The present disclosure concerns an assembly for a drug delivery device (1)comprising a housing (3), a first abutment surface (64), a second abutment surface (21), and a detachable member (7) which is detachable from the housing (3) and attachable to the housing (3), wherein the assembly is configured such that, during detachment of the detachable member (7) from the housing (3) for an Nth time, N being a predetermined number, the first abutment surface (64) is brought into abutment with the second abutment surface (21), wherein the assembly is configured such that, when the first abutment surface (64) abuts with the second abutment surface (21), the detachable member (7) is enabled to be reattached to the housing (3) and, afterwards, the detachable member (7) is prevented from being detached from the housing (3).

An electronic inhaling device for detachably receiving a spray bottle having a bottle body with a spray mouth, includes: a casing formed with a vertical slide slot, in which the spray bottle is adapted to be disposed slidably; a bottle support seat installed in the casing, having a receiving inlet permitting extension of the spray mouth of the bottle body when the spray bottle is seated on the support seat and a discharging outlet in spatial communication with the receiving inlet in order to discharge a volatile substance sprayed out from the spray mouth of the bottle body via the discharging outlet; and a monitoring module disposed in the casing for monitoring movement of the spray mouth relative to the bottle body, counting a discharged number of the volatile substance sprayed out from the spray mouth of the bottle body via the discharging outlet.

An inhaler, preferably for insertion into a nostril, in particular a horse's nostril, with a pressure generator, which has a tensioning device for the drive, and with a tensioning mechanism for tensioning the tensioning device, whereby the tensioning mechanism has a lever gear for tensioning the tensioning device.

An activation mechanism for an aerosol dispenser is presented having a first housing structure, an actuation member movably arranged in the first housing structure, wherein the first housing structure is provided with an actuation member opening in level with the axial position of the actuation member, and an activation member slidably attached to the first housing structure, the activation member slides between a non-triggering position and a triggering position relative to the first housing structure, wherein the activation member has a radially flexible tab portion that is offset from the actuation member opening when the activation member is in the non-triggering position, restricting radial flexing of the tab portion, and wherein the tab portion aligns with the actuation member opening when the activation member is in the triggering position, thereby enabling the tab portion to flex radially inwards to cause movement of the actuation member.

An arrangement for activating an aerosol dispenser having a conveying tube for conveying a liquid; a movable holding member holding the conveying tube; a rotatable base; and a container chamber between the holding member and the base, wherein the arrangement is configured to transmit a loading rotation of the base to a substantially axial loading movement of the holding member towards the base, and wherein the holding member has a locking structure exposed to the container chamber. An aerosol dispenser having the arrangement and a method for activating an aerosol dispenser are also provided.

A nebulizer and a housing part comprising a blocking device as well as use of a blocking device are proposed. The blocking device blocks a rotatable element of a counter device in a defined rotational position until the nebulizer is closed.

A dose counting mechanism for an aerosol dispenser is presented where the dose counting mechanism has a first body structure, a second body structure rotatably attached to the first body structure, an annular dose counter provided with a plurality of teeth along its perimeter, the dose counter being arranged coaxially with the first body structure and the second body structure, each of the first body structure and the second body structure being rotatable relative to the dose counter, a rotatable actuator that meshes with the teeth of the dose counter, the actuator being configured to follow the perimeter of the dose counter when the second body structure is rotated relative to the first body structure, and a rotator that rotates concurrently with one of the first body structure and the second body structure and that engages with the actuator when rotation of the first body structure relative to the second body structure is initiated.

A simulated smoking device (1) comprising a simulated cigarette having a substantially cylindrical cigarette-like shape and a refill device (2, 50) having a substantially cuboid housing with a cigarette pack-like shape containing refill gas (32, 59) for the simulated cigarette and having means for selectively retaining the simulated cigarette. The simulated cigarette may be retained wholly within the housing. It may be retained at a location different from the refill location. A dose counter may be provided to give a visual indication of the doses in the refill device.
