A pump for dispensing a fluid product from a product container, includes a unitary pump body defining an axis and including a pump chamber, a pump inlet and a pump outlet. The pump chamber is collapsible over an axially directed pumping stroke from an initial condition to a collapsed condition and is biased to return to its initial condition in a return stroke. An axially compressible spring is arranged to at least partially support the pump body during its collapse.

A fluid pump includes a plastomer spring. The spring includes a first end portion and a second end portion and a plurality of rhombus shaped spring sections, joined together in series at adjacent corners and aligned with each other in an axial direction to connect the first end portion to the second end portion. The spring sections can be compressed in the axial direction from an initial condition to a compressed condition and can subsequently expand to their initial condition.

A pump includes a housing forming a chamber; a dispensing opening; and a regulator fixedly arranged in the chamber. The regulator includes an inner valve for regulating a flow of liquid between the container and the chamber; an outer valve for regulating a flow of liquid between the chamber and the dispensing opening; a stem resilient along its length, sideways bendable, and extending in a longitudinal direction of the housing between the inner valve and the outer valve; and a displacement guide located at an outer portion of the stem on an inner side of the outer valve. An outer perimeter of the displacement guide and a portion of an internal surface of a guide region located adjacent the displacement guide are adapted to transfer the sideways bending of the stem to a relative displacement between the outer valve and the housing along the longitudinal direction of the housing.

Disclosed is a pump assembly having slidingly engaged upper and lower sleeves, and a pump having inlet and outlet ends and a pump chamber therebetween. Movement of the lower sleeve towards the upper sleeve causes the pump chamber to reduce in volume. The outlet end of the pump has a shoulder between a first diameter portion and an outlet nozzle extending downwardly from the shoulder and having a second diameter smaller than the first diameter portion. The lower end of the lower sleeve includes a shied extending from a lowermost rim upwards and inwards to terminate at an orifice that is larger than the second diameter but smaller than the first diameter portion. The shoulder supporting against a lip of the orifice and the outlet nozzle extending through the orifice to terminate at a dispersion location within the shield at a distance L from the orifice.

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.

Exemplary embodiments of tabletop dispensers are disclosed herein. An exemplary tabletop dispenser for dispensing soap, sanitizer or lotion includes a bottle. The bottle has a neck that has a neck diameter. A pump assembly having a cylindrical housing is also included. The cylindrical has a cylindrical housing diameter that is less than the neck diameter. A controller board, a battery, a motor and a pump are at least partially located within the cylindrical housing. The pump assembly is configured to be located within the neck and the bottle. A sensor for sensing an object and an outlet nozzle are also included.

A manually operated demand delivery liquid pump dispensing device, includes: a container (2) to be filled with a storage (20) of the liquid to be dispensed and with air inside the container, said container comprising a bottom part (6), a top part (5), and a side wall (7) between said bottom part and said top part, and a lid (3) which seals an opening (4) in the top part of the container, usable for filling the container, said lid being provided on the upper side thereof with a shallow basin (15), including, in the centre thereof, a concave dish-shaped cavity (21) and a discharge opening in the region of said dish-shaped cavity of the lid, and with a tube (22) for supplying liquid to said concave dish-shaped cavity from said storage of liquid which may be contained in the container. Said tube has an exterior top section (22a) extending upwards from the bottom of said concave dish-shaped cavity (21), and an interior section (22b) extending downwards from said top section into the storage of the liquid which may be contained in the container.

An adaptor assembly for use in a dispenser for a replaceable fluid container comprising a fluid reservoir and a fluid pump. The adapter assembly is used in conjunction with the dispenser to allow a use of a fluid container having a pump being actuated by laterally compressing it. The adaptor assembly comprises an actuation part being movable, when mounted in the dispenser, and comprises a first contact surface for abutting against the user actuator and a second contact surface for abutting against the pump. The adaptor assembly also comprises a first connecting support for removably connecting the actuation part to the dispenser and/or the fluid dispensing package mounted in the compartment. A fluid dispensing system including the adaptor assembly is also disclosed.
