摘要： Dispensers are provided of the type which include a flow path through which liquid must pass to leave the dispenser. After the dispenser has been actuated to dispense, the flow path then receives reverse flow as the dispenser recovers ready for the next dispensing. This reverse flow limits the possibility of dripping from the dispensing outlet. A flow controller in the flow path automatically adjusts to have little or no interference to the flow of liquid leaving the dispenser and then positions itself to slow down the rate of reverse flow into the dispenser. The dispenser is suitable for more viscous liquids.

摘要： A dispenser is provided for liquids which responds to actuation either by squeezing or by some other action to cause dispensing. Liquid is stored in an enclosure and an outlet structure has an outlet passageway which carries liquid from the enclosure to exit outside the dispenser. A buoyant bell combines with the passageway to trap liquid in the enclosure. If preferred, upon actuation liquid will flow initially, and then the bell can be made to seal the outlet structure to stop liquid flow thereby simulating a pumping action.

摘要： La presente invencion se refiere a un distribuidor de líquidos, el cual es del tipo que tiene un recipiente resilente, acoplado a una estructura de salida, que incluye un deposito para contener un volumen del líquido, con aire dentro del deposito arriba del líquido, la estructura externa también incluye una abertura de descarga, espaciada arriba del volumen del líquido y en comunicacion con el aire dentro del deposito, arriba del líquido, para mantener presion dentro del deposito, cuando el distribuidor no está en uso, el líquido dentro del recipiente se mantiene por una zona de presion negativa, arriba del líquido dentro del recipiente, y una estructura de salida, que define una trayectoria de flujo para que el líquido fluya desde el recipiente a través del deposito hacia arriba a la abertura de descarga, el distribuidor se caracteriza por la combinacion de la abertura de descarga estando arriba del deposito, de modo que un usuario que oprima el recipiente, causará que el nivel en este deposito se eleve, mientras la abertura de salida iguala la presion con la atmosfera, hasta que el nivel en el deposito sea tal que el líquido fluya a través de la abertura de salida, y un controlador de flujo colocado en la trayectoria de flujo, este controlador tiene una primera condicion en la cual el controlador de flujo presenta resistencia mínima al flujo del fluido, y una segunda condicion, en la cual el controlador suministra una abertura de acceso ce cierto tamaño, para permitir el flujo del líquido a un régimen predeterminado, el controlador de flujo es operable automáticamente en respuesta a que el usuario deforme el recipiente para mover el líquido hacia afuera a lo largo de la trayectoria de flujo, para mover el controlador de flujo en la primera condicion, en la cual este controlador exhibe resistencia mínima al flujo durante la distribucion, y luego en respuesta al movimiento del líquido al interior, a lo largo de la trayectoria de flujo, cuando el usuario relaja el recipiente, para mover el controlador de flujo a la segunda condicion, en la cual este controlador disminuye el régimen natural del flujo del líquido a lo largo de la trayectoria de flujo, de manera que hay menos probabilidad de que el aire sea atrapado en el líquido y el deposito es tal que el aire que entra en el distribuidor será recogido dentro del deposito, arriba del volumen del líquido y entrará en el recipiente solamente si el nivel del deposito cae suficientemente para que el aire desde el deposito entre en el recipiente para reemplazar el líquido distribuido.

摘要： A dispenser for liquid is provided having a relatively stiff or rigid container above a resiliently deformable reservoir structure. The container is coupled to the reservoir structure and the container has a bottom outlet inside the reservoir structure which also includes a discharge structure leading from the inside to the outside of the reservoir structure. Liquid is dispensed when the user causes relative movement between the container and the reservoir structure to increase the pressure in the reservoir structure and to thereby force liquid from the reservoir structure through the outlet passageway.

摘要： A dispenser for liquids is provided having a container including a bottom opening and an envelope structure surrounding the container. A bottom wall on the envelope structure is adjacent the bottom opening so that liquid from the container will collect in the envelope structure about the bottom opening. A dispensing passage is coupled to the envelope structure and leads from inside the envelope structure below the bottom opening upwardly and terminates outside the envelope structure. At least a portion of the envelope structure is resiliently deformable for deflection to create pressure in liquid in the envelope structure to thereby cause liquid to exit through the dispensing passage.

摘要： PCT No. PCT/CA93/00258 Sec. 371 Date Mar. 1, 1994 Sec. 102(e) Date Mar. 1, 1994 PCT Filed Jul. 2, 1993 PCT Pub. No. WO94/01032 PCT Pub. Date Jan. 20, 1994.A dispenser for liquids having a rigid container (22, 52, 74) for storing the liquid at a first level and a reservoir (24, 54, 76) below said first level providing liquid communication with the container so that some liquid at a second level in the reservoir traps the liquid in the container due to the build up of a negative pressure in the container above the first level of liquid. An outlet passageway (41, 50, 78) has an inlet positioned normally in the liquid below the second level and extending upwardly from the inlet and terminating outside the dispenser. Displacement structure (28, 56, 94) is operably coupled to the reservoir for increasing the pressure in the reservoir to thereby dispense liquid through the outlet passageway.

摘要： Dispensers for liquids are provided having structure for containing a pool of liquid in the dispenser, to a predetermined level. A discharge chamber contains air above the level of liquid and a discharge device extends upwardly at least partly through the discharge chamber from below the level of the pool and has an external outlet. The discharge device includes a foamer chamber having a wall defining very small holes located above the pool level, and pressure means is coupled to the discharge chamber and operable to increase the pressure in the discharge chamber so that a pressure applied on the pool level drives liquid into the discharge device. Simultaneously air is forced through the small holes in the foamer chamber to meet the liquid passing through the foamer chamber where progressive foaming takes place before the resulting foam is forced through a discharge outlet.

摘要： A dispenser is provided for liquids, the dispenser (28, 70, 110) having a container (30, 72, 112, 144, 156) and an outlet at a predetermined first level. The pressure in the container can be varied and a reservoir (44, 98, 122 and 128; 148, 174, 180) receives liquid from the outlet. A discharge passageway (46, 88, 128 and 136, 150, 184) extends upwardly from the first level and terminates at a discharge opening (52, 90, 154) at a second level, and an air relief opening (56, 102, 130, 152, 160, 182) is provided above the first level. The relief opening is no lower that the second level so that liquid displaced from the container flows into the reservoir and out of the passageway while air is trapped in the reservoir above the first level. Consequently any gradual increase in temperature will cause air from the reservoir to be displaced through the air relief opening to minimize the risk of temperature driven dispensing.
