A barrel (20) adapted for use with a spray gun (2) is disclosed. The barrel (20) comprises a boost feed port (44) fluidly connected to a boost passageway (48), the boost passageway (48) being integral to the barrel (20). The boost passageway (48) is adapted to convey a pressurized boost fluid originating in the spray gun (2) to a boost delivery port (56) to assist in urging a coating fluid from a compatible coating fluid reservoir (80) for spraying by the spray gun (2).

Container assemblies (100) that transition between a sealing state and a retained venting state are described. The container assemblies each include a body portion (110) having an open end (113), and a lid portion (120) adapted to cover the open end of the body portion to create an enclosed volume, e.g. reservoir, and additionally comprise a venting feature (140). When the fluid pressure within the enclosed volume is less than a threshold pressure, the lid portion is in a sealing state such that the lid portion and the body portion cooperate to maintain a substantially fluid-tight seal against fluid leaving the enclosed volume. When the fluid pressure is greater than or equal to the threshold pressure, the lid portion is in a retained venting state such that the excess fluid pressure from the enclosed volume vents through the venting feature while retaining the lid portion on the body portion.

In accordance with an example embodiment, there is disclosed herein a sprayer operable to dispense fluid from a fluid reservoir, such as a paint reservoir. The sprayer comprises a rechargeable battery pack that can be employed to provide power to a pump. The pump provides air to a nozzle assembly that is mixed with fluid from the fluid reservoir and dispensed via the nozzle assembly. In particular embodiments, the nozzle assembly comprises a disposable tip insert.

A dry fogging system includes a control device including a control device inlet configured to couple to a gas source, a first control device outlet, and a second control device outlet configured to couple to a first tank. The dry fogging system further includes a first spray device including a first spray device inlet configured to couple to the first tank, a second spray device inlet configured to couple to the first control device outlet, and a spray device outlet configured to provide dry fogging.

A device suitable for dispensing a liquid substance, such as an ophthalmological substance, including a container; a dispenser for dispensing the substance and which includes a piston element, loaded by the pressure of the pressurized substance so as to adopt a standby position by default that prevents the preloading chamber from being flooded by a dose of the substance; and a valve element capable of enabling a connection between the preloading chamber and the outside. The device has an actuation mechanism that sequentially compresses a volume of air used for moving the piston element from the standby position thereof, allowing a dose of the substance to flood the preloading chamber to subsequently mechanically actuate the valve element and simultaneously enable the connection to the outside of the preloading chamber as well as of the volume of air previously used for moving the piston element from the standby position thereof.

A liquid spray system (100) comprises a housing (110), a spray applicator (120) and an air pressurising device (130). The housing (110) comprises a retaining section (140) to receive a receptacle (200), the receptacle (200) comprising a flexible body (201, 202) having a reservoir (204) comprising a liquid for spraying, and a liquid outlet (205) in fluid communication with the reservoir (204). The retaining section (140) also comprises a receptacle compressor (170) configured to apply a compressive force to the flexible body (201, 202) to force liquid from the liquid outlet (205) of the receptacle (200). The spray applicator (120) is disposed remotely from the housing and in fluid communication with the liquid outlet of the receptacle (200). The air pressurising device (130) is in fluid communication with the spray applicator (120) to propel the liquid from the spray applicator (120).

A dispenser system for applying multi-component adhesives or like substances to work surfaces in carpeting, roofing and like applications as well as a method of dispensing and applying multi-component adhesives to work surfaces.

The present disclosure is directed to a holder. The holder includes a package including a containment portion and a separable portion, wherein the containment portion is separated from the separable portion by perforations, and a sheet within the package, the sheet including a first surface and a second surface, the second surface opposed to the first surface, the first surface operably attached to the separable portion, the sheet configured to extend a distance along an interior of the containment portion, wherein at least a portion of the first surface of the sheet contacts the interior surface of the containment portion, and wherein a liquid composition contacts a second surface of the sheet.

A dispenser system for applying multi-component adhesives or like substances to work surfaces in carpeting, roofing and like applications as well as a method of dispensing and applying multi-component adhesives to work surfaces.

A liquid spray assembly (la) comprises a liquid spray apparatus and a liquid, for example a paint. The spray apparatus comprises a reservoir (100) for the coating liquid, a spray applicator (300), and means for urging liquid from the reservoir (100) to the spray applicator (300). At the outlet of the spray applicator (300) the liquid is atomised by a flow of primary pressurised gas; and downstream the atomised spray profile is modified by a flow of secondary pressurised gas. It has been determined that the effective use of this type of spray apparatus can be achieved by using a particular class of coating liquids, which have a defined solids content, viscosity and amount of an organic or organically modified thickener, of which over 50 wt% is an organic or organically modified associative thickener. A method of using the liquid spray apparatus is also described.
