Abstract:
A nonaerosol foamer comprised of an outer container or bottle and novel internal labyrinth structure comprising a slotted body covered along one face with a film of durable synthetic resinous material whereby separate air and liquid influent channels, a foaming site, and a separate foam effluent channel are defined. The liquid influent channel is constructed such that it allows controlled movement of the foamable liquid from the liquid reservoir to the foaming site during application of positive pressure within the outer container, while preventing siphoning of the foam. A novel film flap valve controls flow of influent air into the container to replenish air earlier used to produce foam.
Abstract:
This invention relates to a spray nozzle for fitment to a "squeeze" container. The nozzle features a gas-liquid mixing chamber which provides for axial and radial mixing of fluids in the container during the dispensing cycle. The spray nozzle of this invention provides a spray dispensing mode even when the container is inverted.
Abstract:
A mouth closure assembly for the mouth of a foam liquid dispensing container adapted to mix foamable liquid and air together and dispense the mixture in the form of a foam aerosol. The mouth closure assembly comprises a foaming portion fitted in the mouth of the dispensing container and including a check valve and a porous member and a foam liquid dispensing portion surrounding the foaming portion and including a cavity defined therein and a closure cap fitted on the top of the foam liquid dispensing portion. The foam liquid dispensing portion covers both the foaming portion and container mouth and is secured to the mouth.
Abstract:
A right-angle spray-nozzle for a squeeze bottle is in the form of a one-piece body and utilizes only one velocity-increasing orifice, thereby avoiding the undesirably slow venting associated with a squeeze bottle having a high velocity jet of liquid that intersects with a second high velocity jet of air.
Abstract:
A squeeze type foamed liquid dispensing device comprising a squeeze container, an inner cap threaded on the container and defining a mixing chamber receiving a secondary porous foaming member thereabout, a check valve chamber, an air intake port and an air discharge tube receiving portion, an outer or cover cap releasably fitted on the inner cap for normally closing the air intake port and having a foamed liquid jet orifice and an air discharge tube received in the air discharge tube receiving portion of the inner cap and having a primary porous foaming member thereabout.
Abstract:
An improved nozzle assembly for manually actuated foam generating and dispensing units in which a tapered bottle cap fitted at its interior end with a dip tube subassembly, is provided with a movable porous element which, upon discharge of foam from the dip tube subassembly, effects a further reduction in bubble size in the foam thereby to provide a stiffer and more consistent foam. The movable porous element floats in the nozzle between a position of seating against the tapered internal nozzle surfaces and a retracted position allowing air to return about the member back to the interior of the generating and dispensing unit.
Abstract:
A bottle and cap of relatively very simple design for spraying an atomized liquid; the bottle being made of squeezable material so that air and liquid within its interior can be together forcibly pushed outwardly therefrom through a common port leading from an air-liquid mixing chamber in the cap, the air being originally admitted into the bottle through a one-way valve which automatically closes when the bottle is squeezed.
Abstract:
Closure for squeeze bottle is provided with swirl chamber into which liquid and air from inside the bottle are introduced. Either the liquid or the air, or both, are introduced to chamber tangentially, and air and liquid are worked therein under conditions of high shear. Fine, well-atomized mist discharges from central orifice from chamber. Orifice may be aimed axially or angularly to axis of container.
