  • Publication number: 20060071030
    Abstract: A pump-action nozzle is described. The nozzle includes an internal chamber and an outlet through which fluid is dispensed and ejected from the device. The outlet has an outlet valve configured to open and permit fluid to be dispensed from the chamber only when the pressure therein exceeds a predetermined minimum threshold pressure. The nozzle also includes an inlet through which fluid can be drawn into the chamber. The inlet has a valve configured to open and permit fluid to be drawn into the chamber only when the pressure within the chamber falls below the external pressure. The body of the device includes a base portion and a housing portion, together defining the internal chamber of the device and being slidably mounted to one another such that said housing portion can be slid towards the base portion to reduce the internal volume of the chamber.

  • Patent number: 6959879
    Abstract: A nozzle arrangement which is suitable for use in the generation of a spray or aerosol and which is adapted for connection to a fluid supply, the nozzle arrangement including a fluid inlet through which fluid enters the arrangement from the fluid supply and fluid outlet through which the fluid is ejected from the nozzle arrangement, fluid inlet and fluid outlet being connected to a fluid flow passage through which, in use, fluid flows from the inlet to the outlet, wherein the nozzle arrangement includes control means provided in the passage which, in use, acts to modify the flow characteristics of the fluid in the fluid flow passage to effectively control fluid droplet size produced in the spray or aerosol by the nozzle arrangement.

  • Patent number: 6953159
    Abstract: An improved spray through cap assembly (10) comprises separable base (11) and cover parts (13). The base part includes a hollow actuator (17) which is adapted to cooperate with an outlet of an aerosol or the like. The actuator is linked to a fluid flow channel (19) formed by correspond recesses in the base and cover parts, respectively, and a nozzle outlet (20). Depressing the cover part causes the actuator to actuate the outlet and causes the contents of the aerosol to be discharged through the nozzle outlet via the fluid flow channel. In order prevent accidental discharge, in one embodiment, the base part includes a projecting lip (22) and the cover part includes a nose (21), the lip and nose cooperating in an inoperative position to prevent the actuator actuating the outlet. In a further embodiment, the cover part is formed from two separable parts and the fluid flow channel and nozzle outlet are formed by corresponding recesses in the parts of the cover parts.

  • Publication number: 20050189382
    Abstract: The present invention relates to a device that is adapted to be placed inside a container and to permit the continuous dispensing of a liquid stored in a container by enabling the fluid to be drawn from the interior of the container into the device and from the device to the outlet of the container. The device has a body which defines an internal chamber, an inlet through which liquid may be drawn into the chamber, and an outlet through which liquid can be drawing out of the chamber. The inlet of the device is adapted to restrict the access of liquid to the chamber when the device is inverted from a upright position. The present invention also relates to a dip tube and various container assemblies that are likewise adapted to permit the continuous dispensing of a liquid stored in a container.

  • Publication number: 20050062202
    Abstract: A method of manufacturing a split nozzle arrangement includes injecting a mixture of a plastic base material and a foaming or blowing agent into a mold of the nozzle arrangement, allowing the plastic base material to set or harden and subsequently removing the final molded nozzle arrangement from the mold. The foaming or blowing agent produces bubbles or pockets of gas in the plastic base material and thus forms a final molded article in which at least 90% of the bubbles or pockets of gas have a maximum dimension of 0.5 millimeters or less. The plastic base material can be, for example, a thermoplastic material and the foaming or blowing agent can be, for example, a mixture of bicarbonate of soda and acetic acid.
