The present invention relates to hair treatment systems. More specifically the present invention relates to a treatment application apparatus, as well as a range of tablets and sprays for use with said apparatus.

A wear part includes at least one wear component made from abrasion-resistant material and an upper seal groove around a central aperture on the upper face of the wear part. The upper seal groove is adapted to receive an axially compressible seal. A spray nozzle assembly includes at least one wear part made from a hard and abrasion-resistant material and a protective housing made from a strong and resilient material and having a downstream chamber adapted to receive one or more of the wear parts in releasably trapped relationship, the downstream chamber having a wall including a post defined by a slot in the downstream chamber wall either side of the post, the post including an inwardly extending protuberance at or near its end and adapted to prevent the wear part from escaping from the downstream chamber.

A nozzle includes a nozzle body defining a liquid circuit extending from a liquid inlet to a liquid outlet. The liquid circuit includes a plurality of spiral liquid passages spiraling radially inward relative to a spray axis. The spiral liquid passages all lie in a plane normal to the spray axis. A manifold assembly includes a plurality of such nozzles. A manifold ring is in fluid communication with the liquid inlet of each of the nozzles to deliver liquid to the nozzles. The nozzles are circumferentially spaced apart around the manifold ring.

A process for flushing a dispenser that dispenses liquids, especially perfumes, containing microcapsules. The dispenser has a first reservoir for a first composition containing microcapsules and a second reservoir for a second composition containing a volatile solvent. The dispenser also has a swirl chamber and a premix chamber. The process simultaneously pumps the first and second compositions into the premix chamber and then into the swirl chamber. The pumping of the first composition is halted while the pumping of the second composition continues, and this provides an extra volume of the volatile solvent, which flushes the dispenser to prevent clogging by the microcapsules.

A multi-mode fluid nozzle includes a generally-cylindrical mixing chamber with a stream mode fluid inlet connected to one side of the chamber, a fluid outlet connected to the opposite side of the chamber and a mist mode fluid inlet connected to the periphery of the chamber. The discharge pattern of the multi-mode fluid nozzle is dependent upon the inlets from which fluid enters the mixing chamber such that when the fluid enters the mixing chamber through the stream mode fluid inlet, the fluid exits the fluid outlet in a stream flow discharge pattern, when the fluid enters the mixing chamber through the mist mode fluid inlet, the fluid exits the fluid outlet in a mist flow discharge pattern and when the fluid enters the mixing chamber through the stream mode and the mist mode fluid inlet, the fluid exits the fluid outlet in a droplet flow discharge pattern.

A jet regulator (1) for a sanitary faucet (2) that contains a first spray plate (3) for dispensing the liquid as a laminar jet; and a second spray plate (4) for dispensing the liquid as a mist jet. Moreover, a sanitary faucet (2) having such a jet regulator (1) is proposed.

An actuator for dispensing the liquid contents of a container in the form of a spray includes an actuator cap, an axial spray channel with an orifice for spraying the contents of the container, and an axial feed channel for connection a container outlet to the spray channel. A breakup wedge is provided in the feed channel such that it splits the feed channel into two sub channels, each connected via a side inlet opening with an inlet portion of the spray channel. Thus, in use, a flow of content is split into two sub flows by the breakup wedge, which sub flows subsequently collide in the inlet portion of the spray channel causing a turbulent flow of the liquid product in the inlet portion of the spray channel, which turbulent flow is guided by the spray channel towards and out of the dispensing opening.

A spray nozzle comprising a housing including a primary passage defining a primary axis, a series of secondary passages configured to provide swirl to a fluid passing therethrough circumferentially positioned around the housing, a series of standoffs circumferentially spread around an outer surface of the housing and located downstream along the primary axis of the series of swirling passages, wherein each of the swirling passages corresponds to a respective standoff of the series of standoffs, in order to control the swirl of the fluid.

A spray orifice structure for which, when spraying liquid contents onto a body part, such as a face, hair, an upper body or a lower body, by using a spray type container, it is possible to provide a user with a differentiated spray performance depending on each body part to be sprayed by manufacturing a spray orifice in consideration of an injection angle to which liquid contents are sprayed.

A trigger-type liquid ejector includes: an ejector main body; and nozzle member provided with an ejection hole. The ejector main body includes: a vertical supply pipe for sucking-up liquid; an ejection barrel communicating with the inside of the vertical supply pipe; and a trigger mechanism including a trigger, the trigger being arranged to be movable rearward in state of receiving forward force, and the trigger mechanism being lead liquid from the vertical supply pipe into the ejection barrel in accordance with rearward movement of the trigger and to eject the liquid from the ejection barrel. The nozzle member is provided with: a cylinder communicating with the inside of the ejection barrel through a supply hole; a plunger accommodated in the cylinder to be movable rearward in a state of receiving forward force; and a communication hole allowing the inside of the cylinder and ejection hole to communicate with each other.
