Provided is a discharge apparatus for an air vehicle, capable of reducing a loss of discharge pressure from an aerosol container. The discharge apparatus for an air vehicle discharges contents from an aerosol container 10 mounted on an airframe 101 through a nozzle 15. The aerosol container 10 is mounted on an exterior of the airframe 101, and one end of the nozzle 15 is supported by a discharge end part of the aerosol container 10 via a pipe joint 17 that allows the nozzle 15 to rotate so as to be rotatable around at least one rotation axis M.

The present disclosure discloses and describes a vapocoolant dispenser. Specifically, the dispenser comprises a housing and container of vapocoolant, the dispenser configured to receive a sterilizable dose of high energy radiation and to provide a sterile, hermetically sealed vapocoolant dispenser.

A dispenser includes a thermal storage tip and a housing having a reservoir for containing a product, such as a cosmetics product or a medicinal product. The thermal storage tip comprises a material that is capable of storing and retaining thermal energy during application of the product.

A method is provided for extracting liquid from a liquid dispenser The dispenser includes a liquid container and, connected to the container, a liquid dispensing device is able to take up liquid from the container and convey it along a path as far as at least one liquid outlet so as to dispense this liquid to the outside. The method includes a step of injecting a volume of extraction gas under pressure into the container so as to apply pressure to the liquid of the container in order to cause it to flow along at least part of the device and allow a predetermined quantity of liquid to be extracted from the dispenser.

To provide a propellant which has sufficient propelling performance and of which a component to be sprayed imposes low environmental burden, a propellant composition and a sprayer. A propellant composition comprising a propellant containing 1-chloro-2,3,3,3-tetrafluoropropene and a pressurizing agent, and a sprayer comprising the propellant composition, a container in which the propellant composition is contained, and a spray unit to spray the propellant composition to the outside of the container.

A nozzle and spray dispenser for generating a uniform substantially flat fan spray pattern when spraying high viscosity fluids (i.e., oils, lotions, cleaning liquids, shear-thinning liquids and gels and similar Newtonian and non-Newtonian fluids having viscosities of 10-100 cP) is configured with an exit orifice 134 defining multiple lip segments 150A, 150B, 150C. Cup-shaped nozzle member 100 has a cylindrical side wall 102 surrounding a central longitudinal axis and has a circular closed end wall with at least one exit aperture passing through the end wall 112. At least one enhanced exit orifice structure is formed in an inner surface of the end wall, and includes two to five lip segments of selected width defining edges at the orifice 134, where each edge segment is defined at the distal edge of a separate and distinct interior wall segment 160A, 160B, 160C which has a selected wall convergence angle β.

Various embodiments of the present disclosure provide a combustion-powered fastener driving tool fuel cell assembly including a fuel cell, fuel cell adapter, and fuel cell adapter cap for a combustion-powered fastener driving tool. The fuel cell, the fuel cell adapter, and the fuel cell adapter cap enable both the fuel cell adapter and the fuel cell adapter cap to be attached to a fuel cell and particularly a sealing member of the fuel cell in one efficient step. This single step process can be done manually or automatically, and is substantially more efficient and less time-consuming than the known fuel cell assemblies.

An aerosol product comprising an aerosol container comprising a container body and an aerosol valve fixed to an opening of the container body, and an aqueous concentrate and a propellant being filled in the aerosol container, wherein the aqueous concentrate comprises an active ingredient having reactivity with oxygen, and an inert ingredient is present in at least a part of an injection passage of the aerosol valve, even though the aqueous concentrate comprising an active ingredient having reactivity with oxygen is filled, oxidation of the active ingredient is inhibited in the aerosol valve, and an aerosol product that can be stored stably for a long period of time and a method for manufacturing the same can be provided.

A barrier package aerosol container includes a can, valve, and piston disposed in the interior volume of the can. The piston is movable toward a top end of the can to facilitate dispensing of flowable material in the can. Opposing surfaces of the piston and the can and the valve define an interstitial space of the interior volume in which the flowable product is receivable. The piston is contacts at least one of the interior surface of the can at its top end and the valve, to define a piston interface when the piston is at the top end of the can during use. At least one of the piston, the can, and the valve defines one or more flow passages at the piston interface to allow flowable material in the interstitial space to flow through the piston interface toward the valve inlet during use.
