A valve dispenses flowable product from a container. The valve includes a mounting cup for mounting the valve on the container, a seal supported on the mounting cup, and a valve stem extending through the seal. The seal and the valve stem define a generally annular passage section of the valve passage that extends longitudinally along the valve axis radially between the valve stem and the seal. At least one of the valve stem and the seal includes a baffle extending transverse to the valve axis, the baffle defining a flow restriction along the generally annular passage section.

A certain amount of contents is easily sprayed by one pressing operation. A metered spray unit 10 being mounted on a stem 23 of a valve 22 that is provided on the upper portion of a container body 21, configured to spray a certain amount of contents in a container body 21, includes an outer cylinder 30 which is provided with a stem insertion hole 30a into which the tip of the stem 23 is inserted and the inner wall thereof is fixed to the stem, a metering chamber 35 connected to the stem insertion hole 30a, the metering chamber being an internal space having a predetermined capacity, connected to the stem insertion hole 30a, and an spray port 33 communicating with the metering chamber 35, a plug member 40 that is inserted from the inside of the metering chamber 35 into the spray port 33 for blocking the spray port 33, a push button 51, an elastic member 60 for supporting the push button 51 on the outer cylinder 30, and a shaft member 50 connected to the push button 51. The elastic member 60 has an amount of displacement due to the pressing force applied to the push button 51, being smaller than the amount of displacement when applying the same pressing force to the spring for urging the stem 23 within the valve 22.

An aerosol foam dip tube dispenser with an axis of symmetry with a pressurizable outer container for storing a propellant and a composition under pressure and an actuator. The aerosol dispenser is ergonomic and promotes upright dispensing in order to avoid degassing.

A pump dispenser includes an actuator having at least one outward projection and a rotatable actuating collar at least partially surrounding the actuator and having at least one ramp rib defining a lower surface which engages the at least one outward projection such that rotation of the rotatable actuating collar acts on the actuator to dispense a product from or through the pump dispenser.

A safety lid for an aerosol container, including a dome surrounding at least part of a diffuser device and provided with a movable component, which can move between a first position for preventing the operation of the diffuser device, a second position for intermittently activating the diffuser device and a third position for emptying the container. The movable component including means for permanently activating the diffuser device in the third position.

Embodiments herein describe a portable device for administering a physiologically active liquid that includes a container for holding the liquid, pressurizing means for applying pressure to the liquid, an atomizer for atomizing the liquid, and an applicator for administering atomized liquid. The atomizer includes at least one nozzle through which liquid can be ejected from the container and an impact element on the nozzle outlet side that is functionally combined with the nozzle. Moreover, the atomizer is configured in such a way that, in a pressure range that can be generated with the pressurizing means, liquid emerging from the nozzle breaks up into droplets prior to striking the impact element.

An aerosol sprayer may be connected to an aerosol container to form an aerosol delivery system. The aerosol sprayer includes a base secured to the container, a cap secured to the base, a pivoting trigger and a sliding nozzle body with an integrated nozzle/manifold which is slidably movable relative to the trigger between an extended operable position and a retracted, locked position. The nozzle includes flexible articulating wall structures adjacent to the manifold to accommodate movement of the nozzle body. The nozzle and trigger have interfitting locking structures to prevent actuation of the trigger when the nozzle is in the retracted locked position.

An actuator cap (1; 50) for a fluid spray dispenser comprises a second body part (2) and a first body part (3). The first body part (3) is adapted for connection to a container for the fluid to be dispensed and incorporates a spray channel arrangement (4). The second body part (2) incorporates an actuator button (5) and is rotatable with respect to the first body part (3) from a first position in which the actuator button (5) is non-elevated into a second position in which the actuator button (5) is elevated and capable of depression to cause depression of a part (16) of the spray channel arrangement (4). The actuator button (4) defines a first cam profile (20) along which a first cam follower (22) defined by the first body part (3) travels to cause elevation or retraction of the actuator button (5) when the second body part (3) is rotated. The actuator button (5) also defines a second cam profile (23) that bears against said part (21) of the spray channel arrangement (4) such that when the actuator button (5) is in its elevated position and depressed the actuator button (5) depresses the second cam profile (23) and in turn depresses the part (21) of the spray channel arrangement (4) relative to the first body part (3) to dispense fluid from the container when in use. Preferably, the first and second body parts (3, 2) are individual, integrally moulded components that are snap-fitted together to assemble the actuator cap (1; 50).

A dispenser having a fluid reservoir (1); a dispenser member (2) having a body (21) and an actuator rod (22) movable over a maximum rod stroke; a dispenser orifice (46); a rotary actuator member (4); a transmission member (5) that is engaged both with the dispenser member (2) and also with the rotary actuator member (4); and a cam mechanism (43, 55) for transforming turning of the rotary actuator member (4) into an axial movement of the actuator rod (22) or of the body (21). The cam mechanism (43, 55) defines a maximum cam stroke that is greater than the maximum rod stroke; and a resilient mechanism (56) acts axially to compensate for the extra amount of the maximum cam stroke and thus allow it to be followed so as to guarantee that the rod performs its maximum stroke in full.

A spray system for dispensing a homogenous mixture of a liquid formulation and propellant as an atomized aerosol where a fill cup containing a liquid base is connected to a charge can to pressurize the inside of the fill cup and to act as a propellant. The charge can is attached to the fill cup through a fitting in fluid communication with the interior of the fill cup, where the fitting may be configured to allow the pressurized charge can to be detached after adding a propellant compatible with the liquid base to the fill cup. Preferably the liquid formulation is a paint base that can be tinted at the point of sale before charging with the charge can.
