Abstract: A dispenser for a pressurized container is provided with an outlet channel that opens into a nozzle housing intended to receive and retain a nozzle (40) provided with a retention ring (43). The nozzle housing has a tubular wall (34) that is open towards the outside at its end opposite to the outlet channel. The tubular wall (34) is provided, at a distance from its end open towards the outside, with a support surface (341) that extends over at least a portion of its periphery and behind which at least a portion of the retention ring (43) of a nozzle introduced into the nozzle housing can come into engagement.

Abstract: A dispensing system includes a housing, a discharge outlet, and a trigger having a grip portion pivotably coupled to the housing to rotate from a first position to a second position. The grip portion has an upper surface and an interior surface disposed below the discharge outlet when the dispensing system is in an upright position. The upper surface of the grip portion moves outward when the grip portion rotates from the first position to the second position to enable at least one of the upper surface or the interior surface to direct a fluid product discharged via the discharge outlet into an interior of the housing.

Abstract: A dispensing system includes a container and an overcap. The container includes a central, longitudinal axis and a first outermost point. The first outermost point of the container is a first distance from the central, longitudinal axis along a first line perpendicular to the central, longitudinal axis. The overcap is coupled to the container and includes a pivotable trigger that is configured to pivot between an unactuated position and an actuated position.

Abstract: 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.
