Abstract: A lotion pump includes a movable portion and a stationary portion. A shifting mechanism is formed on the movable portion and the stationary portion, which shifts the elastic restoring mechanism of the lotion pump between a standby state and a non-standby state as the movable portion rotates or moves up and down. The structure of the lotion pump can prevent the spring from yielding due to compressed for a long time, while can also realize a form of locking at lower position.

Abstract: A valve spring made of plastic, in particular for pretensioning a valve stem against a valve seat of a dispensing unit for dispensing a preferably liquid product, is proposed, wherein the valve spring has a plurality of spring elements arranged axially one behind the other, in particular along an axis or longitudinal axis. According to a first aspect, each spring element has two curved portions which are formed mirror-symmetrically with respect to one another and are connected to one another at their ends. According to a further aspect, the valve spring has a leaf-spring-like or cup-spring-like construction.

Abstract: The invention relates to the field of inhalation devices for liquids. In particular, the invention relates to a liquid emission mechanism for an inhalation device, as well as a method of emitting a liquid from an inhalation device.
The inhalation device comprises a housing (1), a reservoir (2) for storing a liquid, a pumping unit, said unit comprising a riser pipe (5), a hollow cylindrical part (3) having an interior space and being linearly moveable on the riser pipe (5), wherein the pumping chamber is fluidically connected with the reservoir (2), and a nozzle (6) which is connected liquid-tight to an downstream end portion (5B) of the riser pipe (5), and wherein said linear relative motion can be effected by a relative rotation around a rotational axis (R) of a rotatable part (1A) with respect to a counterpart (1B), such that said relative rotation is converted into said linear relative motion by means of a gear mechanism comprising at least one cam surface having a first section (9A) and a second section (9B), and wherein a means for the storage of potential energy (7) is provided. The device is characterized in that said cam surface has, between the first section and the second section (9A, 9B), a third section (9C) of constant height, such that, while said counterpart (1B) slides along said third section (9C), no linear relative motion occurs.
A method for the generation of an aerosol comprises, upon rotation of the rotatable part (1B), a first, charging phase for filling the pumping chamber with liquid, and a second, discharging phase for emitting the atomized liquid from the nozzle (6), and is characterized in that between said two phases, a third, resting phase exists during which, despite further rotation, the volume of the pumping chamber remains constant.-

Abstract: Provided is a trigger assembly for an atomizer and an atomizer that includes the trigger assembly. The trigger assembly includes a trigger ring and a delivery tube holder. The trigger assembly has a locked position and an unlocked position. In the locked position, the trigger ring stops axial movement of the delivery tube holder, and in the unlocked position, the delivery tube holder can move in an axial direction relative to the trigger ring. The trigger assembly further includes an actuation member. The actuation member is actuated to drive the delivery tube holder to pivot and drive the trigger ring to move, so that the trigger assembly is switched between the locked position and the unlocked position.

Abstract: A fluid product dispenser having a vessel and provided with a neck forming at least one helical thread, and a dispensing head mounted on the neck of the vessel, the head having a dispensing member and a fastening member engaging both with the threaded neck and the dispensing member The fastening member has a deformable and malleable skirt intended to engage with the threaded neck, and a rigid collar engaged around the skirt to push the skirt radially against the threaded neck in such a way as to deform the skirt against the thread so as to create a thread imprint in the skirt. The helical thread has an intermediate portion that has, on at least some of its length, a cross-section that decreases in the unscrewing direction and increases in the screwing direction, such that the unscrewing torque decreases and the rescrewing torque increases.

Abstract: A fluid dispensing system including a fluid dispenser that is operable in a stand-alone mode, and a housing that is configured to removably receive the fluid dispenser for operation of the fluid dispenser in a housed mode. When the fluid dispenser is placed on top of a horizontal support surface for operation of the fluid dispenser in the stand-alone mode, a pump mechanism of the fluid dispenser is manually activatable to dispense an allotment of fluid by manually depressing an activation member of the pump mechanism. When the fluid dispenser is received by the housing for operation of the fluid dispenser in the housed mode, the pump mechanism is activatable by activating an actuation mechanism of the housing

Abstract: A tamper resistant dispensing system has a liquid product dispenser having a container body adapted to contain the liquid. The container body has an externally threaded neck that extends to an opening, and a dispenser cap that includes an actuator, an internally threaded closure, and a stem. The internally threaded closure threadedly mounts upon the externally threaded neck such that the stem extends into the container body. A tamper resistant overcap has an annular body adapted to be positioned around the internally threaded closure of the dispenser cap. The annular body has a height and a width that are great enough to substantially cover the internally threaded closure, a pair of access holes are on opposite sides of the annular body.
