Definitions
- This invention relates to a directional spray actuator.
- the invention particularly relates, but is not limited to, a bi-directional spray actuator for a pressurised (e.g. aerosol) container.
- a simple "valve actuator” is fitted to a valve stem in communication with the interior of the container, and is provided with a nozzle, arranged to produce a cone-like spray pattern.
- the valve stem When the valve stem is operated e.g. depressed by the valve actuator, the stem causes the valve in the container to release a portion of the liquid contents (and propellant) from the container, to be released in the spray pattern from the nozzle.
- the actuators may comprise a body (mountable on the container), a nozzle, and a trigger hingedly mounted on / on the body, and the nozzle communicates with the interior of the container via a product passageway connected to a valve in the container and an orifice in the nozzle.
- Many of the known spray actuators have at least one limitation in their manner of construction and/or their method of operation. For example, they can only be operated by either a finger-operated trigger or a finger- (or thumb-) operated "button". They are usually not capable of being easily operated when the container is in a number of different orientations, or where alternative spray patterns are to be applied.
- Spray actuators previously designed to overcome, or at least ameliorate, these known limitations, are typically complex, and thereby, expensive to. manufacture.
- the present invention resides in a directional spray actuator for attachment to a pressurised container containing at least one liquid to be dispensed, the container having a valve and valve stem, the spray actuator including:
- a body having a sidewall, to enclose and/or releasably engage an upper portion, of the container;
- valve actuator movably mounted on the body, having a passageway therethrough, the passageway having an inlet operably connectable to the valve stem and an outlet;
- a nozzle component rotatably mounted on the body
- each product passageway having a respective inlet portion and nozzle portion;
- the inlet portion of the second product passageway being at an angle to the inlet portion of the first product passageway
- the respective inlet portions are selectively connectable to the outlet of the product passageway to enable the at least one liquid to be dispensed in respective directions relative to the container.
- valve actuator is hingedly mounted on the body about a hinge axis.
- the inlet portion of the second product passageway is at substantially a right-angle to the inlet portion of the first product passageway, to enable the at least one liquid to be dispensed in a first direction aligned with the valve stem and in a second direction substantially perpendicular thereto.
- the inlet portions are provided in a body portion of the nozzle component
- the body portion has a curved external wall for sealing engagement with the outlet
- the nozzle portions are provided in an extension portion which extends substantially perpendicular to the hinge axis.
- the body portion is of substantially cylindrical or spherical shape
- the outlet is of substantially oval or elliptical shape
- At least one sealing member is provided to sealably interconnect the outlet and the respective inlet portions.
- Each nozzle portion may have a nozzle designed to dispense the at least one liquid in a selected spray patterns, where the spray patterns may be identical or different.
- each nozzle portion may have a recess, or nozzle receiver, to receive a replaceable nozzle insert.
- a replaceable nozzle insert may be mounted on a distal end of the extension portion. The nozzle insert may be connected to both of the nozzle portions; or each nozzle portion may be provided with a respective nozzle insert.
- the sidewall has a rim engaging portion for attachment to the container and/or a skirt depending from the sidewall of the body; and the body and the valve actuator are formed with an integral hinge forming the hinge axis.
- the present invention resides in an aerosol container containing at least one liquid to be dispensed, the container having a valve and valve stem, provided with the directional spray actuator hereinbefore described.
