The device contains a passage for foam return from a foam conduit to a liquid reservoir having one-way valve means to permit flow only in the direction from the foam conduit to the liquid reservoir during operation of the foamer, and a means of separating the inlet to the air passage from the outlet of the foam return passage to prevent flow of foam through the air passage during rapid, repeated foam dispension.

Abstract: A spray dispensing device is provided which can be used with non-pressurized containers. The device includes passageways for directing streams of air and liquid to a mixing chamber wherein the liquid is broken up into droplets and emitted as a fine spray through an orifice.

Abstract: A manually operated continuous aerosol sprayer which eliminates the need for the use of potentially environmentally dangerous substances. A container is provided to hold a liquid and an inflatable bladder is located inside the liquid container. A pump is provided for filling the bladder with air from the outside atmosphere. The open end of the inflatable bladder is attached to the pump so that it may be readily filled by the pump with the remainder of the inflatable bladder extending into the liquid container. When the bladder is inflated it expands causing the liquid in the container to become pressurized. The pressure from the inflation of the bladder causes the air and the liquid to be forced into a spray chamber where they mix and are forced out a spray nozle as an aerosol spray.

Abstract: A device is provided for controlled dispensing of a measured quantity of fluid from a flexible container. The device has a chamber adapted to hold a measured quantity of fluid when the container is inverted and righted. This fluid is then dispensed from the chamber through a conduit in direct response to a force exerted on the flexible wall of the container.

Abstract: A fluid dispenser includes a resilient housing having opposing walls. A conduit leads from the interior of the housing to its exterior, and may be used to conduct the fluid from the interior of the housing to its desired end location. A serrated member is affixed to the interior of one of the opposing walls, and a pin is affixed to the other wall. When pressure is exerted on the opposing walls, the pin slides along the serrations of the serrated member, causing an interruption of the continuous pressure exerted on the walls, thereby causing the fluid to be delivered in a pulsed stream.

Abstract: The dispenser has a circular mixing chamber (8) which is arranged immediately in front of a mixing nozzle (7). A first channel (15) leads to the mixing chamber (8) which is connected with a rising pipe which is immersed in the filled material of a squeezable container. Simultaneously, a second channel (9) leads into the mixing chamber which is connected to the air space above the filled material. A sieve arranged in the outlet channel (19) at a distance after the mixing nozzle which completely covers the outlet channel under the effect of the pressure of the filled material flowing out when the container (1) is squeezed. With release of the container, the sieve partially releases the outlet channel under the suction effect of the air return flow. With that, the container is rapidly ready for a renewed press sequence.

Abstract: A bag in squeeze bottle fluid dispenser capable of dispensing substantially all of the fluid product contained therein. A suitable bag support element is inserted inside the flexible bag to prevent substantial axial movement of the bag in the direction of its discharge orifice and to encourage radial collapse of the bag instead. The internal bag support means, which in a preferred embodiment comprises an extruded plastic helix, has an internal fluid passage formed within the coils of the helix and fluid communication to allow fluid contained within the bag to access the internal fluid passage along substantially the entire length of the internal bag support element. Thus, radial collapse of the flexible bag does not block the passage of fluid remaining in the bag through the discharge orifice in the bag until substantially all of the fluid contained within the bag has been dispensed.

Abstract: The present inventon is a liquid metered dispensing container of the squeezable type. The squeezable container has an opening for dispensing liquid therefrom at one end and a bottom at the other end. A non-flexible trap chamber is connected to the opening and extends outwardly therefrom. The trap chamber has a lower end inserted into the container opening and has an inlet orifice extending from the lower end into the container. The inlet orifice is adapted to receive a dip tube which is attached thereto and extends close to or at the bottom of the container. The trap chamber has an upper end with a dispensing orifice. This is small enough to prevent dripping of liquid therefrom by gravity when the bottle is inverted but is large enough to dispense liquid therefrom when the bottle itself is squeezed. A one way valve is connected to the lower end of the trap chamber which permits liquid to flow from the container to the trap chamber but not vice versa.

Abstract: The present invention comprises a spray bottle in which the pressure resulting from the gripping force applied by the user is amplified and this increased pressure used in generating a spray such as an aerosol or fluid stream. In its preferred embodiment, the invention includes a high pressure chamber and a corresponding piston which is operative for driving fluid out of this chamber at high pressure through a spray nozzle and a low pressure chamber and a corresponding piston which is acted upon the hydraulic pressure within the bottle resulting from the gripping force. The low pressure chamber and piston are of larger size than the high pressure chamber and piston. The pistons are rigidly connected so that the force created by the pressure acting on the piston in the low pressure chamber is transmitted to the piston in the high pressure chamber where it is applied over a more limited area thereby generating greater hydraulic pressure for use in forming the spray.

Abstract: The present invention provides a dropper tip suitable for dispensing small-volume droplets of fluid with a minimum drop-to-drop volumetric variation. The dropper tip includes a minimum-surface dispensing tip and a similar minimum-surface interior configuration that minimizes the surface area available at the entry port of the dispenser tip for the aggregation or adhesion of bubbles. In the preferred embodiment, the minimum-surface configuration allows for uniform drop formation at the tip whether or not the dropper is in a vertically inverted or inclined position when dispensing. The interior configuration likewise minimizes the surface area available for air bubbles to congregate or adhere and thereby minimizes the probability of an air bubble reentering the dropper tip when dispensing the second or subsequent drop. A cap effects sealing on a surface other than the tip so that repeated capping and uncapping will not degrade the minimum-surface rim.
