A sprocket assembly comprising a mount; and a sprocket having an opening for receiving the mount such that the sprocket can rotate around the mount, the sprocket having a plurality of radially extending fluid pathways extending from the opening to a radially distal edge, wherein the mount includes a manifold for fluid to be supplied to the sprocket, the manifold having a fluid exit channel towards the opening of the sprocket such that each radial pathway in the sprocket is in fluid communication with the manifold over only a part of a rotation of the sprocket about the mount.

A device for delivering a substance in the form of aerosol is described. The device is used with a syringe equipped with a plunger and without a needle. The delivery device comprises: a connection sleeve for connecting the device with the syringe; a nozzle for delivering the substance as aerosol, preferably with troncoconical walls and obtained on an elongated outer body of the device; and a fluid-dynamic path comprised between the connection sleeve and the dispensing nozzle, wherein the path comprises an annular expansion chamber and an elongated acceleration chamber, so that, while in use, a manual actuation of the plunger introduces the substance into the fluid-dynamic path in a liquid form through the connection sleeve and produces the substance as aerosol through the dispensing nozzle.

Methods and systems using magnetism to securely hold detachable spray-extension straws to aerosol cans to prevent their misplacement or loss are presented. Created from inexpensive magnetic plastic material: one is a magnetized straw that alone will securely attach to a spray can, and others are a variety of magnetized devices that will affix the straw on the surface of spray cans by magnetic attraction forces. Each device variation is designed to grasp and hold a conventional plastic straw while magnetically attached to an aerosol can.

An article including a cap (10) for a can (100), the article including: (a) a first section (20), where the first section fits over the top (110) of the can and attaches to the can; and (b) a second section (30) that is movably attached to the first section so that it is movable from a closed position generally above the top of the first section to an open position generally alongside the first section.

An actuator for a spray can. The actuator includes a housing for attachment to an aerosol can covering a stem valve. A finger operating button structure is engaged with the housing for engaging the stem valve. A rotary two-way diverter valve is supported within the housing and rotatably engaged with the finger operating button structure. In a spray position/straw down, the two-way diverter valve directs spray through a first direct spray nozzle. In a second straw position/straw up, to make use of an adjustable straw, the diverter valve is rotated to engage a straw spray passage of the diverter valve in fluid communication with an adjustable rotary spray tip and engaged straw. By rotating the adjustable rotary spray tip to an aligned position, the tip substantially blocks the straw spray passage to provide a drip mode, where drops of fluid exit the straw. A flexible tip may optionally be provided on the straw to enable bending and retention of the flexible tip to a desired position.

Heads for an aerosol container are disclosed. The head comprises a handle body having a base configured to be coupled to the aerosol container, an outlet, a flexible tube housed within the handle body. The flexible tube is configured to provide fluid communication between the container exit of the aerosol container and the outlet. And the head further comprises an elastically deformable actuator comprising a lever arm, and a coupling portion integrally formed with the lever arm and configured to be mounted around the flexible tube, wherein the coupling portion is further configured such that when the lever arm is deformed by a user, the coupling portion actuates on the valve body of the aerosol container. Aerosol containers comprising such heads and kits for treatments skin lesions are also disclosed.

A dispensing device dispenses a liquid held in a container. The device includes an engagement portion for the mutual engagement of the device and the container. Drawing and dispensing means draws the liquid from the container to dispense it. A main operating body operates the drawing and dispensing means through pressure exerted along a pressing direction. The main operating body moves with respect to the engagement portion, when subjected to pressure, between a rest position and an activating position. A dispensing nozzle is fixed to the main operating body and provided with a dispensing duct suited to dispense the liquid. The dispensing nozzle is switched from the main operating body, through a rotary movement, between a dispensing position and a non-dispensing position. Constraining means prevents the movement of the main operating body along the pressing direction when the dispensing nozzle is in the non-dispensing position.

The invention relates to an adapter for a product dispenser (11) with an adapter base body (19) for positioning the adapter (18) on a container opening (14) of a pressure container (12), with a swivel arrangement (23), which adjusts an actuating lever (21) with a handle (22) swivellably to the adapter base body (19), wherein the actuating lever (21) is transferable from an unlocked position (67), in which the handle (22) can be operated from a starting position (68) into an active position (69) for opening a valve (16) of the container (12), to a locked position (66), in which operation of the handle (22) is blocked.
