A assembly for dispensing a fluid product having a first fluid-product dispenser with a first reservoir, a first dispensing member, such as a pump, provided with a first dispensing head and a first pusher, and a second fluid-product dispenser with a second reservoir, a second dispensing member, such as a pump, provided with a second dispensing head and a second pusher. The second dispenser is removably mounted on the first dispenser so as to prevent the actuation of one of the two dispensers.

A stem (1) for a two-way valve has a main body (10) outer face that is substantially cylindrical about a main axis, with (i) a first tubular wall (11) closed at its lower end by a first bottom wall (13) and open at its upper end (111), defining a central
channel (113); (ii) a second tubular wall (12), concentric with the first tubular wall (11) and partially surrounding it, closed at its lower end (122) by a second bottom wall (14) and open at its upper end (121), defining an annular channel (123) around the central channel (113), one or more through-holes (124) bringing the inside of the annular channel (123) in contact with the cylindrical outer face of the main
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 assembly for dispensing a fluid product having a first fluid-product dispenser with a first reservoir, a first dispensing member, such as a pump, provided with a first dispensing head and a first pusher, and a second fluid-product dispenser with a second reservoir, a second dispensing member, such as a pump, provided with a second dispensing head and a second pusher. The second dispenser is removably mounted on the first dispenser so as to prevent the actuation of one of the two dispensers.

The present invention relates to a package. More particularly but not exclusively it relates to package that is rupturable so as to create an opening in the package, yet the package is resistant to rupture from undue forces from particular directions due to a convex shaped burst region that requires straightening to burst.

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.
