body (10); and (iii) a tubular insert (20) dimensioned so as to be able to be inserted into the annular channel (123).

Provided is an aerosol product which has a simple configuration and enables spraying in the form of a mist at the time of use even when a stock liquid is stored in a high-viscosity state in an aerosol container. An aerosol product (100) has a plurality of partitioned housing spaces and a valve unit (120) provided with an inflow port (122) corresponding to the housing space, wherein at least one among the plurality of housing spaces is a main stock liquid housing section (142) that houses a main stock liquid (M), at least one other of the plurality of housing spaces is a viscosity lowering agent housing section (143) that houses a viscosity lowering agent (S), and the main stock liquid (M) discharged from the inflow port (122) and the viscosity lowering agent (S) discharged from the inflow port (122A) are mixed in an actuator (130).

A fluid dispenser (1) for dispensing a cosmetic composition (2) comprises a housing (3), a dispenser head (4), at least one first receptacle (16) being connectable to a first reservoir (5) comprising a first fluid (6), and at least one second receptacle (17) being connectable or connected to a second reservoir (7), the second reservoir (7) being configured to receive a second fluid (8). The fluid dispenser (1) further comprises a mixing area (18) being in fluid communication with the dispenser head (4), the first receptacle (16) and the second receptacle (17). The mixing area (18) is configured such, that the cosmetic composition (2) is generated when a dose of the first fluid (6) is mixed with the second fluid (8) within the mixing area (18).

This disclosure discloses various dispensation devices for dispensation of various volumes of content. For example, some of such content can include cream.

A polyurethane composition raw material liquid agent comprises a polyol or an isocyanate, and a filler. The polyurethane composition raw material liquid agent has a viscosity at 25° C. and a rotation speed of 60 rpm of 950 mPa.Math.s or less, and is filled in at least one cartridge-like container of a caulking gun that includes two cartridge-like containers and is capable of mixing two components.

Assembly comprising a spray means, preferably an airbrush comprising a pickup chamber subjected to a stream of entrainment air, and a dispenser comprising at least two compartments containing different base products, the compartments being pressurized by way of volumetric dosing devices, and the products being delivered to the spray means preferably via distinct dispensing orifices.

The present disclosure describes devices, systems, and methods for the production and/or delivery of a foamable and/or flowable material for consumption, such as by direct application to a consumer, such as directly to the mouth of the consumer. A device and/or system for converting a material from a first, unfoamed state to a second, foamed state is provided, and a device and/or system for converting a material from a first, non or semi-flowable state to a second, flowable state is provided.

An aerosol can configuration includes an outer can, an inner container and a spray head with a discharge element. The spray head has an outlet valve connected to the interior of the outer can and an outlet valve connected to the interior of the inner container. The two outlet valves are opened jointly by pressing on the spray head, so that the contents of the outer can and the contents of the inner container jointly enter the discharge element. To form a foam, the outer can contains at least 30-70% by weight isocyanate, in particular diphenylmethane 4,4′-diisocyanate, 3-15% by weight polyol with an OH number of less than 300, and 5-30% by weight liquid gas at a critical temperature of ≥+70° C. At least 5-30% by weight polyol with an OH number of more than 300, and 1-10% by weight liquid gas with a critical temperature of ≥+70° C. are contained in the inner container.

A flow reducer (10) for a pressurized product dispenser of the type provided with a valve (30) equipped with a stem (20) having at least a first path, and with a diffuser, is a part separate from the stem and the diffuser, and includes a recess open on one side via an opening and adapted to be fitted by the opening over the stem (20) of a valve (30), one or more first outlet orifices (134) which, when the reducer is mounted on the stem (20) of a valve, are adapted to be connected in a sealed manner to the first path of the stem (20) of the valve, thus forming an extension (133) of the first path, the outer face of the reducer, on the side opposite to the opening of the recess, having in part a contour substantially identical to that of the portion of the stem (20) protruding from the valve which is intended to be covered by the reducer.

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.
