Abstract: An outlet valve assembly for a fluid dispenser of a type having a pump fluidically coupled to a fluid reservoir includes an outlet nipple having a proximal end configured to be fluidically coupled to the pump and a distal end opposite the proximal end. The outlet nipple defines a conduit extending in a flow direction and has an annular protrusion extending radially inwardly intermediate the proximal end and the distal end. An outlet nozzle is coaxially received within the distal end of the outlet nipple. A resiliently deformable valve member is received within the conduit. The valve member includes a valve head portion having one or more slits defining an orifice and a peripheral valve portion outward of the valve head portion. The peripheral valve portion is retained between the annular protrusion of the outlet nipple and an end edge surface of the outlet nozzle.

Abstract: An outlet valve assembly for fluid dispenser includes an outlet nipple having a proximal end for fluidically coupling to a pump and a distal end and defining a flow conduit. An outlet nozzle comprises a sleeve and an inward annular protrusion cooperating to define a counterbore coaxially receiving at least a portion of the outlet nipple. A resilient valve member within the counterbore includes a valve head portion and a peripheral valve portion around the valve head portion. The peripheral valve portion is retained between the annular protrusion and the distal end. A vent-resisting member integrally formed within the conduit includes a perforated baffle adjacent a first side, upstream of the valve head portion. The baffle is positioned close to the first side of the valve head portion to resist inward opening of the orifice during operation to prevent inward venting of ambient air during a dispensing operation.

Abstract: An outlet valve assembly for fluid dispenser of a type having a pump which has a pump inlet coupled to a fluid reservoir and a pump outlet includes a pump tip having a first end adapted to be coupled to the pump outlet and a second end defining a conduit extending in a flow direction therebetween. A first annular protrusion extends radially inwardly within the conduit and a resiliently deformable valve member is received within the conduit. The valve member includes a valve head portion having one or more slits defining an orifice and a peripheral valve portion bounding the valve head portion, which is retained on the first annular protrusion. A vent-resisting member is received within the conduit and includes a perforated baffle adjacent to the upstream side of the valve head portion and an axially-extending sidewall which has a distal edge engaging the peripheral valve portion.

Abstract: The present disclosure relates to a fluid dispenser of a type having a housing in which a container filled with a fluid to be dispensed is removably received. The container incorporates a pump and an adapter assembly for securing the pump within an opening or fitment of the container and for removably securing the container within the housing. In another aspect, an improved push bar-type actuator is provided. In certain embodiments, an angled receptacle for receiving the pump and adapter receptacle is provided for ease of emplacing the container within the housing.

Abstract: A pump for dispensing particulate-ladened or heavily viscous fluids such as grit-ladened or granulated hand soap or lotion, has a compressible pump cavity with an inlet and a streamlined outlet, with a backflow check valve associated with the inlet and a nozzle assembly connected to the outlet. In the nozzle assembly, a spring loaded outflow ball valve resists outflow until sufficient fluid pressure is applied from the pump cavity. A minimally flow restrictive spring base support structure holds the base of the spring apart from the nozzle tip, creating a fluid flow path around the check ball and spring to the nozzle tip.

Abstract: The invention in the simplest form is a dispenser that is a teaching tool and uses audio and visual means to promote compliance with proper washing techniques. A detection means is used to commence a time interval, and washing instructions are used to communicate with the user as an instructional tool in washing. There is a feedback response during the washing cycle to walk the user through the washing cycle and provide progress indicators during the cycle. A usage indicator tracks the number of usages as part of a management tool of assessing overall employee performance.

Abstract: The invention in the simplest form is a dispenser valve with an increased flow capacity. The device is particularly suited for dispensing liquids, and has a plurality of individual thin and streamlined elevated standoffs that serve as the spring seat, lowering flow losses and providing a larger flow path area or particulate matter included in the liquid. In addition, the ball check valve chamber is funnel shaped, creating an efficient flow for the dispensing liquid regardless of the viscosity or particulate of the liquid. The unit increases discharge capacity, reduces clogging, improves efficiency, and allows the unit to dispense highly viscous and gritty materials.
