Dispenser with a reservoir comprising a divider or a porous material

A pressurized dispenser, comprising:

• a base around which surrounds a peripheral wall having an open end sealed by a dispensing element comprising a dip-tube, a fluid reservoir in contact with the dip-tube for reducing the compressed gas lost from the pressurized dispenser, a compressed gas and a dispensing liquid,
• wherein a majority of said fluid reservoir being located outside of the dip-tube and the fluid reservoir comprises a porous material, arranged in use to hold a volume of the dispensing liquid, the porous material being configured so that in use at least a portion of any compressed gas in the reservoir can be displaced by the liquid, ejecting said portion of the compressed gas into the dispenser, and
• wherein the dispensing element is configured to dispense the dispensing liquid continuously for at least 0.5 seconds, upon actuation of the dispensing element.

A pressurized dispenser as claimed in claim 1 wherein the porous material comprises a foam or cellular material.

A pressurized dispenser as claimed in claim 1 wherein the reservoir comprises a polymeric material selected from polyurethane, polystyrene, polypropylene, polyethylene, polyvinylchloride or a combination thereof.

A pressurized dispenser as claimed in claim 1 wherein the reservoir holds at least 0.5 ml, at least 1 ml or at least 2 ml or at least 5 ml of dispensing liquid.

A pressurized dispenser as claimed in claim 1 wherein the porous material comprising at least 10 ppi (pores per inch), at least 20 ppi or at least 30 ppi.

A pressurized dispenser as claimed in claim 1 wherein the porous material comprises no more than 80 ppi, no more than 75 ppi or no more than 70 ppi.

A pressurized dispenser as claimed in claim 1 wherein the reservoir forms a barrier within the dispenser through which the dip-tube extends, the dip-tube having a fluid inlet end located at or near the base of the dispenser.

A pressurized dispenser as claimed in claim 1 wherein the dip-tube comprises a fluid inlet at an end thereof, and a second fluid inlet located along the length of the dip-tube, and the reservoir covers both fluid inlets.

A pressurized dispenser as claimed in claim 1, wherein the porous material comprises pores having an average pore size of at least 50 microns, at least 100 microns or at least 200 microns.

A pressurized dispenser as claimed in claim 1, wherein the porous material comprises pores having an average pore size of no more than 1000 microns, no more than 750 microns or no more than 500 microns.

A pressurized dispenser as claimed in claim 1, wherein the fluid reservoir has substantially the same refractive index as the dispensing fluid.

A pressurized dispenser as claimed in claim 1, wherein the dip-tube comprises a fluid inlet at an end thereof, a second fluid inlet located along the length of the dip-tube, and a valve around the second fluid inlet.
