    Abstract: Various means for controlling the rate of travel of a plunger through a pump chamber in a dispensing pump are disclosed including an arrangement in which a cap is slidably mounted to the upper end of the pump plunger and a spring interposed between the cap and plunger with a detent mounted on the container contacting the plunger to prevent downward motion so that as the cap is depressed it is moved downwardly relative to the plunger preloading the spring and in which, after a predetermined degree of motion of the cap relative to the plunger, the lower end of the cap releases the detent to that the preload expands driving the plunger downwardly at a uniform rate. In another illustrated embodiment a preload spring is disposed within the pump between a plunger stem and plunger piston, the hydraulic forces within the pump chamber permitting the spring to be compressed before an outlet passage is opened, the spring once again acting to permit uniform discharge. In another embodiment, detents inside the pump cause an operator to build up a certain amount of finger pressure to overcome the detents whereby, the pressure having been built up in the finger, the operator will smoothly and quickly discharge material.

    Abstract: A dispenser pump is disclosed of the moveable-nozzle type, arranged for sealing a vent path in the extended position of the pump plunger. A pump body includes an internal collar formed at the lower end of a tubular insert, through which the vent path passes. This collar has a seal portion. The plunger has a complementary seal portion which makes a guided and fitting engagement with the collar seal portion. One or both of the plunger seal portion and the collar seal portion is formed as an annular taper, so that the seal portions are guided into close engagement with one another. Plunger lock-down formations are constructed to engage at the bottom of the body insert and remain below the top opening of the body.

    Abstract: A pre-compression pump (10) dispenses microdoses of fluid (F). The pump minimizes pulsing due to pressure fluctuations. The pump is provided with the following to limit pulsing: a low force slow return velocity return spring (46); enlarged fluid passage (58); elastic bumper (74); and, a rachet tooth (76) bearing against the stem (44). Further, a deflectable diaphragm (90), a splined (70) stem (44), no dip tube, and an off-center, gravitational low-point pump inlet (62) assist in printing the pump. The pump includes a stem (44) with deflectable fingers (92) to ensure sufficient momentum in pump operation. Detents (118) and grooves (120) selectively lock a nozzle cap (14) in an inoperative position. To ensure cleanliness, nozzle (60) cleaning is provided, wiping of the nozzle to remove meniscus (M) therefrom, cuts (104) formed in a shroud (98) assist in drawing excess fluid from the nozzle, and an empty volume (108) for collecting fluid run-off from the nozzle. A handle (H) is mounted to the pump providing a grip.

    Abstract: The invention relates to a foam-dispensing device for dispensing a foam, comprising a manually operated pump assembly. The pump assembly comprises a liquid piston pump for pumping the liquid, and an air pump for pumping air, the liquid and air to be pumped being mixed together to form a foam which is dispensed through a dispensing aperture. The liquid piston pump comprises a pump housing, for example a cylinder, a liquid piston which is movable telescopically in the pump housing, and one or more sealing elements to be fixed on the liquid piston in order to seal the liquid piston in the pump housing. The liquid piston comprises at least two locations for fixing the one or more sealing elements. The invention further relates to a kit for producing a piston with one or more sealing elements for such a dispensing device, and a method for producing a piston pump for such a dispensing device.
