Dispensers having a liquid reservoir filled with a main liquid and having a dispensing head, with a dispensing opening and a dispensing channel, which connects the reservoir outlet to the dispensing opening. The dispensing head can be pressed down to actuate the switching valve or the conveying device. The liquid dispenser has a replaceable exchange unit, which, in a functional state, forms the dispensing channel at least in some sections. The exchange unit has a mixing chamber, with an addition medium and an inlet and an outlet separated from the inlet. The exchange unit is part of the dispensing channel such that the inlet is communicatively connected to the reservoir outlet and the outlet is communicatively connected to the dispensing opening. Furthermore, the exchange unit has closures at the inlet and at the outlet to close the mixing chamber.

The present application relates to the design of a class of beauty products that facilitates personalized replenishment. The physical product is a new type of case comprising one or two sides or chambers, where each chamber retains a cartridge of a specific type of product, such as a foundation. For example, in an embodiment where the case of the present invention comprises a single chamber product, the cartridge may contain a single type of foundation. In an embodiment where the present invention comprises a case capable of retaining two cartridges, or comprises two product chambers, one cartridge may hold a relatively lightweight foundation, and the other may hold a long-wear foundation.

Includes an electromechanical device (1), which acts like an electronic catalog for the olfactory testing of different fragrances or aromas, contained in an absorbent cylindrical element (2) inserted into individual cartridges (3), which are interchangeable and encased in a carousel (4), supported on central bearings (5) and radially moved by means of an electric motor (6) with reducer (7) and gearing (8) that acts in a circular rack (9). Upon receiving a command, via application, the carousel (4) turns positioning the cartridge (3), corresponding to the fragrance or aroma chosen, in front of the connector nozzle (10), thanks to a positioning sensor (S), which counts the turns of the shaft of the electric motor (6). Next, a mechanical actuator (11) formed by an electric motor (12), gearing (13) that acts in a straight rack (14), which in turn drives a drawing cane (15), which pushes, and then retracts the cartridge, (3) inside the connector nozzle (10), and jointly with the air flow coming from a flexible hose (16), from where the air inflated by a compressor (17) enters said cartridge (3), forces the emission of the scent by the outlet orifice (18) of the top (19) of the box (20), thus providing the user a reliable olfactory testing.

A bottle includes a squeezable main chamber configured to dispense a bulk liquid; a cap that dispenses the bulk liquid; and a bulkhead between the main chamber and cap, wherein the bulkhead supports a cartridge containing an additive liquid that is dosed into the bulk liquid.

An adapter receives two separate fluids from a container having two separate fluid compartments and combines the fluids into a single fluid stream for delivery to a spray fluid dispenser. The adapter comprises a unitary housing having a first open end for fluid connection to the container and a second open end for fluid connection to the spray fluid dispenser. The housing defines a manifold forming a fluid passageway therein between the first end and the second end. The manifold includes two separate first conduits formed at the first end. Each of the first conduits is connected to a respective one of the fluid compartments. The manifold further includes a second conduit in fluid communication with the second end for delivery of the combined fluids to the spray fluid dispenser. The first conduits are each in fluid communication with the second conduit.

A device for dispensing a product includes: a module including a head and a reservoir, the head including a conduit connecting the inside of the reservoir to an outlet of the head; and a housing having at least two mutually movable parts including an upper part and a lower part, the at least two parts being arranged to be assembled so as to receive the module inside the housing.

A spray device includes a first spray tip having a first fluid pathway defining a first flow area, and a second spray tip includes a second fluid pathway that defines a second flow area that is larger than the first flow area of the first spray tip. The first and second spray tips are side-by-side and spaced from one another at a distal end of the spray device. When a first fluid having a volumetric flow rate is introduced into the first spray tip and a second fluid having the same volumetric flow rate is introduced into the second spray tip, the first fluid will flow through the first fluid pathway at a greater velocity than the second fluid will flow through the second fluid pathway.

A hand cleaner foam dispenser with a first pump arrangement that discharges a first liquid and first air from the atmosphere through a first foam inducing member into a mixing chamber and a second pump arrangement that discharges a second liquid into the mixing chamber, and in which there is a simultaneous discharge of the first liquid, first air and the second liquid from the mixing chamber through an outlet foam inducing member to produce a foamed product delivered onto a person's hand. Preferably, the second pump arrangement may discharge not only the second liquid, but also second air drawn from the atmosphere and discharge the second liquid and the second air through a second foam inducing member into the mixing chamber.

A pump assembly comprises a pump main body having a first cavity and a press rod. The press rod has a rod body and a piston portion in which the rod body is slidably provided in the first cavity in a penetrating manner and one end thereof extends out of the first cavity. The piston portion is connected to the rod body and is located in the first cavity to divide it into a first gas cavity and a second gas cavity, one or more of which are sealed cavities. Since the piston portion can rebound under the resultant force of a gas pressure in the gas cavities, the pump main body does not need a spring for rebounding the rod body. Accordingly, the pump assembly can be entirely made of a plastic material, and no metal material is mixed, so the pump assembly is easily recycled.

The present disclosure relates to aerosol delivery devices. The aerosol delivery device may include a housing; a first aerosol forming unit comprising: a first chamber configured to contain a first liquid composition; and a first metering orifice in fluid communication with the first chamber and configured to selectively release the first liquid composition in the form of an aerosol with particles of a first average size range; a second aerosol forming unit including: a second chamber configured to contain a second liquid composition; and a second metering orifice in fluid communication with the second chamber and configured to selectively release the second liquid composition in the form of an aerosol with particles of a second average size range that is different from the first average size range.
