Sprayhead for a spray device
A sprayhead including; a chassis capable of firm attachment to an aerosol container, the chassis including a circular platform and a peripheral skirt; a rotatable circular collar that includes a bridge that spans a diameter of the collar; and a spray channel and associated actuator button, the spray channel being designed to pass through a central aperture in the circular platform of the chassis and through a central aperture in the bridge; the chassis holding the spray channel and associated actuator button in a non-rotatable manner, and the collar being rotatable between a first position in which the spray channel is incapable of depression and a second position in which the spray channel is capable of depression when pressure is applied to the associated actuator button.
1. A sprayhead comprising:
a chassis capable of firm attachment to an aerosol container with which the sprayhead is designed to be used, said chassis comprising a circular platform and a peripheral skirt;
a rotatable circular collar located around and largely over the peripheral skirt of the chassis, said collar comprising a bridge spanning a diameter of the collar;
a spray channel and an actuator button associated with the spray channel, said spray channel being designed to pass through a central aperture in the circular platform of the chassis and through a central aperture in the bridge spanning a diameter of the collar, and being connectable to the aerosol container; and
an upper body designed to fit over the chassis and the spray channel, the upper body defining a first aperture located over the actuator button and a second aperture surrounding the end of the spray channel to allow passage of a product from an outlet at the end of spray channel;
the chassis holding the spray channel and the actuator button in a non-rotatable manner and the collar being rotatable between a first position in which the spray channel is incapable of depression and a second position in which the spray channel is capable of depression when pressure is applied to the actuator button.
2. The sprayhead according to claim 1 , wherein the first aperture, located over the actuator button associated with the spray channel, is covered by a flexible membrane.
3. The sprayhead according to claim 1 , wherein the bridge has a protrusion from a circular element defining the central aperture in the bridge which interacts with a lateral projection from a central element of the spray channel to prevent depression of the spray channel when the collar is in the first position.
4. The sprayhead according to claim 3 , wherein the bridge has multiple protrusions from the circular element defining the central aperture in the bridge which interact with multiple lateral projections from the spray channel to prevent depression of the spray channel when the collar is in the first position.
5. The sprayhead according to claim 4 , wherein the multiple lateral projections are equally spaced around the circular element defining the central aperture in the bridge and the central element of the spray channel, respectively.
6. The sprayhead according to claim 1 , wherein the chassis comprises a guide slot into which a wing element from a central element of the spray channel fits in order to restrict rotational movement of the spray channel relative to the chassis.
7. The sprayhead according to claim 1 , wherein the chassis restricts rotational movement of the collar.
8. The sprayhead according to claim 7 , wherein the chassis comprises a section protruding from the top of a circular platform thereof, said section limiting rotational movement of the collar by interaction with the bridge spanning said collar.
9. The sprayhead according to claim 1 , wherein the spray channel comprises an upright central segment.
10. A method of applying a cosmetic composition comprising using the sprayhead according to claim 1 to apply a cosmetic composition to a surface of the human body.
11. An aerosol product comprising the sprayhead according to claim 1 and a cosmetic composition for application to a surface of the human body.
