A two component sprayable adhesive and system for spraying is provided. The two component adhesive may have an adhesive, and an activator. These components are mixed after spraying, either in the air or on a substrate. The activator destabilizes the adhesive making it more tacky and effective. In at least one of the two components, an additive is provided to provide a visual indication that the components are mixed and/or properly mixed in the intended ratio.

A mist-generating device includes: a droplet generating unit that generates, in a third liquid, a functional droplet including a first liquid that is spherical and a second liquid that covers an entirety of the first liquid and has a volatility lower than a volatility of the first liquid; and a mist-generating unit that generates a multilayer mist obtained by atomizing the third liquid containing the functional droplet.

A spin caster for spraying a surfacing material upon an interior surface of a vessel includes a spin head configured to rotate about an axis, the spin head including an input port, and a supply line coupled to the input port and configured to convey a first material to the spin head and a second material to the spin head. The supply line comprises a first channel configured to convey the first material to the spin head and a second, different channel configured to convey the second material to the spin head.

The invention relates to the field of nozzles for inhalation devices for liquids. In particular, the invention relates to a nebulizing nozzle for an inhalation device, suitable for the generation of an aerosol of a medically active liquid, and to inhalation devices comprising such nozzle.

Such nozzle (1) for an inhalation device for medically active liquids (F, F1, F2) for generation of an aerosol has a main axis (Z) and at least three ejection channels (1A, 1B, 1C, 1D) adapted to eject liquid (F, F1, F2) along respective ejection trajectories, wherein at least two collision points (X1, X2) are provided at which at least two of said ejection trajectories intersect with one another, and/or wherein further, all ejection angles (A, A1, A2) at which the individual trajectories leave the nozzle (1) are identical, or at least one of said ejection angles (A, A1, A2) differs from the other ejection angles (A, A1, A2).

A spray device includes a first spray tip having a first fluid pathway defining a first flow area, and a second spray tip includes a second fluid pathway that defines a second flow area that is larger than the first flow area of the first spray tip. The first and second spray tips are side-by-side and spaced from one another at a distal end of the spray device. When a first fluid having a volumetric flow rate is introduced into the first spray tip and a second fluid having the same volumetric flow rate is introduced into the second spray tip, the first fluid will flow through the first fluid pathway at a greater velocity than the second fluid will flow through the second fluid pathway.

A discrete dispensed product comprising a first portion; and a second portion at least partially surrounding the first portion provides a premium and distinct appearance to consumers.

In one example, a liquid mixture nozzle for flowing a liquid mixture therethrough includes a body having a flow inlet and a flow outlet. The flow inlet is configured to couple to a first piece of piping and the flow outlet is configured to couple to a second piece of piping. The liquid mixture nozzle also includes a converging section having a decreasing diameter positioned adjacent the flow inlet, an orifice positioned at a narrow end of the converging section, an intermediate section having a constant diameter positioned adjacent the orifice, a diverging section having an increasing diameter positioned adjacent the intermediate section and the flow outlet.

The invention relates to a spray device having a spray nozzle unit and at least one further spray nozzle unit. Each spray nozzle unit has at least one spray nozzle body, wherein said at least one spray nozzle body comprises a chamber for receiving a pressurized fluid. Said chamber is bounded by a spray wall having at least one spray orifice that extends through said spray wall and opens to an external environment. Each of said at least one orifice in a spray wall has a substantially identical predetermined size lying in a predetermined range and releases a mono disperse spray jet of the pressurized fluid fed from the associated reservoir. Said range within said first spray nozzle unit differs from said range within said at least one further spray nozzle unit, particularly said ranges do not overlap.
