A spray canister dispenser for mounting to a spray canister to allow for more convenient actuation of a nozzle. The spray canister dispenser includes a housing that removably mounts to an upper end of a spray canister. A first channel is disposed on an interior sidewall of the housing and can align with a lip of the spray canister to selectively couple thereto. An actuator assembly having a trigger handle and an actuator extends from a moveable plate secured to the housing and can transition between a dispensing and resting configuration. In the dispensing configuration, the actuator is forced against a spray canister nozzle to dispense substance therefrom. In use, the trigger handle is positioned on a forward side of the spray canister, wherein the housing is on a rearward side of the canister. An aperture is disposed within the trigger handle to allow the substance to be dispensed therethrough.

A hose lubricating tool for power line hoses. A backboard has a support plate mounted on the front surface. The backboard has a lip portion below the support plate integral with the bottom half. A hinge is mounted to the front surface and attached thereto is a finger base, the finger base mounted to the hinge on the front surface. An indentation is defined within the finger base underneath the front edge. A finger portion is mounted to the finger base, the finger portion extending out over a finger front edge of the finger base to define a finger tip, the finger tip and finger portion sized to be received within a groove of a power line hose. Upon the power line hose being forced along the finger tip, the finger base is urged downward to engage the trigger and release the lubricant.

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 manually operated applicator for spraying and dispensing expanding foam chemicals from aerosol containers is provided. The applicator dispenses compressed gas in close proximity to the foam as the foam exits the applicator, which results in improved adhesion of the foam to surfaces. The applicator includes a nozzle, an aerosol inlet for connection to an aerosol container, a gas inlet for connection to a source of compressed gas, and a trigger for operation of the applicator. The nozzle includes outlets for dispensing the foam and the compressed gas.

A holding device for a spray container that includes a body, a nozzle portion on a top of the body, and a groove formed between the body and the nozzle portion, the holding device including a base, which is constructed to be placed on a top of the body around the nozzle portion; a pressing part that is connected to a first portion of the base and extends over the nozzle portion, wherein an end of the pressing part includes a first interlocking part; and a first supporting bar which is connected to a second portion of the base, wherein a second interlocking part is formed on or about a top of the first supporting bar and a first protrusion is inwardly formed on or about a bottom of the first supporting bar to detachably couple with the groove.

This content-accommodating container comprises: a container body having an opening at the top end; and a valve-accommodating part for closing the opening, the valve-accommodating part being fixed to the container body. The valve-accommodating part is provided with: a cylindrical housing part accommodated inside the container body; a tube part extending downward from the housing part, the lower end thereof being disposed near the bottom side of the container body; and a first sealing part for closing the bottom end of the tube part.

An adapter receives two separate fluids from a container having two separate fluid compartments and combines the fluids into a single fluid stream for delivery to a spray fluid dispenser. The adapter comprises a unitary housing having a first open end for fluid connection to the container and a second open end for fluid connection to the spray fluid dispenser. The housing defines a manifold forming a fluid passageway therein between the first end and the second end. The manifold includes two separate first conduits formed at the first end. Each of the first conduits is connected to a respective one of the fluid compartments. The manifold further includes a second conduit in fluid communication with the second end for delivery of the combined fluids to the spray fluid dispenser. The first conduits are each in fluid communication with the second conduit.

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 article has a can with a valve stem and a dispensing device, the dispensing device includes a cap over the valve stem, a hollow tube extending through a slot in the cap and attached to the valve stem, a sleeve slidably extending over the hollow tube, a lever hingedly attached to the cap and operatively engaging the sleeve, an elastic feature that provides a force or causes a force to be applied to the sleeve in a direction that tries to move the sleeve to a closed position, and a sealing gasket between the sleeve and hollow tube proximate to the exit end of the hollow tube; where the sleeve seals the hollow tube when in the closed position and displacing the lever towards the can simultaneously unseals the hollow tube and tilts the valve stem, and when released allows the sleeve to restore to a closed position.

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.
