The present invention relates to a system and method for a liquid containing compound/s producing a visible chemiluminescent glow upon being distributed in the atmosphere in the presents of a targeted analyte. It is an object of the present invention to provide a system and method for discharging a chemiluminescent spray into the atmosphere, upon which, in the event of the presence of an analyte, such as H2S, a chemiluminescent reaction occurs.

A container for fluid products, particularly pharmaceutical, cosmetic, medical products or the like includes an hollow body divided into: a first tank containing a first fluid substance and communicating with a first dispensing hole of the first fluid substance; a second tank containing a second fluid substance and communicating with a second dispensing hole of the second fluid substance; a neck associated with the hollow body and on which are formed the first dispensing hole and the second dispensing hole; a selector element associated with the neck by interposition of rotation means able to rotate the selector element around an axis of rotation, and the selector element includes an outlet channel able to dispense selectively, due to the rotation of the selector element, the first fluid substance or the second fluid substance.

A dispensing head including:a cap having: an outer wall with at least one part referred to as the shell part and at least one part referred to as the pressing part that is made of a material more flexible than the at least one shell part; at least one outlet; an insertion orifice,a stopper, the stopper being mounted in the cap by being inserted into the cap from the insertion orifice side and in an insertion direction, at least one assembly, each assembly comprising: an inlet, passing through the stopper; a deformable pocket, an interior volume of which is intended to contain the fluid of this assembly and is delimited at least in part by the at least one pressing part of the cap; preferably a feed duct and/or a dispensing duct.

A sunscreen application assembly includes a canister that has a plurality of chambers. Each of the chambers is fluidly discrete with respect to each other and each of the chambers contains a liquid. A pump unit is movably coupled to the canister and the pump unit is in fluid communication with the interior of the canister. The pump unit is selectively manipulated. The pump unit is selectively aligned with a selected one of the chambers to urge the liquid in the selected chamber outwardly therefrom.

A part of a dispensing apparatus is described. A fluid dispensing apparatus manifold arranged to mix and combine a first fluid from a first chamber and a second fluid from a second chamber has been devised. The manifold includes a first fluid inlet for entry of fluid from the first chamber, a second fluid inlet for entry of fluid from the second chamber, a mixing chamber and a fluid outlet. A first fluid passage is arranged to provide fluid communication for the first fluid from the first chamber to the mixing chamber, and a second fluid passage is arranged to provide fluid communication for the second fluid from the second chamber to the mixing chamber, whereby the first and second fluids are combined into a mixed fluid stream at the fluid outlet.

A dispenser having a fluid reservoir (R) and a dispenser member (D) mounted on the reservoir (R), the reservoir (R) forming a cylinder (11) and including a piston (2; 2) that slides in the cylinder (11) so as to decrease the working volume of the reservoir (R). The leaktight slide cylinder (11) contains a separator element (3a) that divides the reservoir into two compartments (Ri, Rs), namely a lower compartment (Ri) that is defined between the piston (2; 2) and the separator element (3a), and an upper compartment (Rs) that is defined between the separator element (3a) and the dispenser member (D). The separator element (3a) includes at least one through hole (33) that puts the two compartments (Ri, Rs) into communication with each other, the separator element moving in the leaktight slide cylinder in response to the dispenser member being actuated by pressing on the pusher.

A dispenser includes a housing, a cartridge, and a pump assembly. The housing defines an internal volume. The cartridge is coupled with the housing. The pump assembly includes a tube that extends through the cartridge and into the internal volume of the housing. The tube includes a first inlet through which a first liquid is drawn into the tube from the internal volume when the pump assembly is actuated, and a second inlet through which a second liquid is drawn into the tube from the cartridge when the pump assembly is actuated.

A dispenser includes a housing, a cartridge, and a pump assembly. The housing has a first liquid disposed therein, and the cartridge has a second liquid disposed therein. The pump assembly includes a tube. The first liquid is drawn from the housing into the tube through a first inlet in the tube when the pump assembly is actuated, and the second liquid is drawn from the cartridge into the tube through a second inlet in the tube when the pump assembly is actuated. The first and second liquids are combined within the tube to form a mixture.

A process for flushing a dispenser and a process for combining a first composition and a second composition to form a mixture and dispensing said mixture through an exit orifice are provided; assemblies for flushing are also provided.

A two-channel dispensing device intended to close a vial includes two reservoirs (13, 14), two channels having an inlet end opening into one of the reservoirs and outlet end opening outside of the reservoir. First closing means are provided in each channel, which can change from a closed position to an opened position in which a product can exit said reservoir. The two channels are isolated from each other at least between their inlet ends and the respective closing means. The reservoirs are formed by a single flexible pouch separated by a central partition (12) into first and second compartments (13, 14) performing the functions of the first and second reservoirs. The inlet end of the first channel opens into the first compartment (13) and the inlet end of the second channel opens into the second compartment (14), so that a single pouch makes it possible to form two reservoirs.
