A spray foam canister adapter provides a means to attach a convenient trigger assembly to a commercially-available aerosol can containing a spray foam insulating material, for efficient spraying of the insulating material into tight or hard to reach spaces. The canister adapter also provides alternate nozzles and a ninety degree (90) extension for specific insulation spraying applications.

An aerosol foam dip tube dispenser with an axis of symmetry with a pressurizable outer container for storing a propellant and a composition under pressure and an actuator. The aerosol dispenser is ergonomic and promotes upright dispensing in order to avoid degassing.

A holding device is used to maintaining a push button of a spray container to be pressed to release contents without continuous press by an operator. The holding device for a spray container comprises a supporting part which is placed around the push button, an adjusting part having a pillar-shaped portion standing on the supporting part and a diving board-shaped portion connected to the pillar-shaped portion and extending over a top of the push button, on a top of the diving board-shaped portion having a recess; and an auxiliary part being pillar-shaped and standing on the supporting part, having a protrusion toward the adjusting part to be engaged with the recess.

An aerosol actuator having a button actuator on a top surface thereof and a lever actuator extending away from the button actuator may be assembled with an aerosol container and valve to provide ergonomic application of a product utilizing the aerosol actuator.

A pressure pack dispenser (100) for dispensing a product comprises a cylindrical container (401) with a product outlet through which the product is dispensed, a composite piston (408) movably mounted within the container, and a pressurised propellant. The composite piston comprises a first upper piston (409A) coupled to a second lower piston (409B) to permit limited relative axial movement and a viscous sealant material (410) located between the first and second pistons. The propellant comprises a compressed gas which remains in the gaseous phase as the piston (408) moves from a first full position to a second exhausted position, or a mixture of a liquid propellant and a compressed gas selected such that in the full position the mixture is at a pressure greater than the vapour pressure of the liquid propellant. A clearance is provided between the second lower piston (409B) and the container wall (401A) which is filled with the sealant (410) as the composite piston moves to expel product. The viscosity of the sealant and clearance are selected such that a thin film of viscous sealant material (410A) is left on the container wall of the propellant chamber, thereby reducing friction between the composite piston (408) and the container wall (401A). The sealant (410) preferably comprises a mixture of glycerine and starch, and has a viscosity of less than 100 poise and less than 4000 poise at 20 C.

A wrist mounted toy is described wherein a pressurized canister containing a string foam compound, or other pressurizable liquid with mid to low viscosity, is attached to a vessel containing a check valve. A geared-trigger mechanism allows for the user to expel the fluid at a pressure and rate dependent on the pressure he or she places on the lever. Additionally, the actions of removing and replacing the air and fluid canisters provide the user with a more interactive experience compared to a simple load and shoot toy. Many variations can be adapted to the toy to allow for a wide range of uses. The toy allows the user to enjoy a device which resembles the Marvel character's shooter more closely and discharge the fluid to quite a distance.

An article includes an adapter having a flow channel extending through it, where the adapter includes a base, a neck, a bendable segment attached to the base and neck and positioned between the base and neck, and a plunger attached to the neck or bendable segment and extending within the flow channel in the bendable segment.

An article includes a dispenser having a flow channel extending therethrough and having a base, a bendable segment attached to the base, a straw attached to the bendable segment, a plunger attached to the base and extending within the flow channel of the bendable segment; a sleeve extending over at least a portion of the straw, and a trigger hingedly attached to the straw at a hinge point and having a portion above the hinge point engaging the sleeve and a trigger portion extending below the hinge point.
