Various dispensing devices, such as foaming soap pumps, are disclosed. The soap pump can include a fluid storage unit and a fluid handling unit. The fluid storage unit can include a reservoir that is configured to hold a quantity of product, such as liquid soap. The fluid handling unit can include a pumping assembly and dispensing assembly. The soap pump can be configured to withdraw liquid soap from the reservoir, convert the liquid soap to foamed soap, and dispense the foamed soap from the discharge assembly.

A flexible mounting system for a chemical product dispenser includes a dispenser holder and at least one mounting apparatus. The dispenser holder may be attached to the mounting apparatus by means of a releasable connection mechanism. The releasable connection mechanism may provide for attachment of the dispenser holder to the mounting apparatus in multiple orientations. In one example, the mounting apparatus includes a mounting bracket configured for mounting to a support object, such as a wall, table, counter top, cabinet, shelf, cart etc. In another example, the mounting apparatus includes a mounting clamp configured for mounting to ledges, poles, bedrails, handles, etc.

An exemplary refill unit for a foam dispenser includes a container for holding a foamable liquid and a liquid pump connected to the container and an outlet nozzle. The liquid pump has a rigid back plate and a flexible membrane. The flexible membrane and the rigid back plate form an arcuate shaped liquid pump chamber. The rigid back plate has a liquid inlet located proximate a first end of the arcuate shaped pump chamber and a liquid outlet located proximate a second end of the arcuate shaped pump chamber. The liquid pump is actuated by progressive compression of the flexible membrane against the back plate.

An exemplary refill unit for a foam dispenser includes a container for holding foamable liquid and a liquid pump. The liquid pump includes a pump housing and an outlet nozzle with an elongated central axis. The pump housing has an arcuate shaped liquid pump chamber formed by a backing plate. The backing plate includes a liquid inlet and a flexible membrane. At least a portion of the elongated central axis of the nozzle extends through a central area defined, at least in part, by the arcuate shaped pump chamber.

The present invention discloses a fluid dispensing system that includes modularized components such as a flow-out member from which fluid dispenses, fluid displacement mechanism, including electronics associated therewith and a reservoir for storage of fluid. The flow-out member, fluid displacement mechanism, and components constituting the fluid dispensing system including the reservoir may have one of a linear or nonlinear cooperative relationship in terms of connectivity and operation, and may be positioned in one of a close proximity or remote locations from one another. Flow out member is provided that may moved in more that one direction to refill reservoir.

A dispensing system includes a collapsible container for liquid material, such as soap, with an outlet for withdrawal of liquid material during collapse thereof. The dispensing system includes a support structure configured for wall attachment of the dispensing system. The support structure further includes at least one movable follower biased towards a collapsing part of the collapsible container, and a detector for reading the position of the movable follower. Detectable substance can be added to the movable follower or the collapsible container. The detector can actuate an alert indicator for indicating a low level of liquid in the collapsible container. Also a collapsible container with detectable substance is disclosed for use in such a system.
