Abstract: A method of producing a pump body for dispensing fluid product, the body having a casing with an inlet orifice which includes a valve having a ball retained in a cage, the method includes: moulding the casing by forming ribs in relief having two lateral faces which join together along an internal edge and an upper end having a free upper surface; introducing the ball into the cage below the upper ends; deforming the upper ends to form visors extending radially towards the interior of the casing to imprison the ball in the cage; with the ribs being formed with their free surface extending from one lateral edge to the other by forming a dome having a top, with the deformation of the upper ends being provided by causing a matrix to bear against the tops then via axial displacement from the matrix on a stroke for crushing domes.

Abstract: A refillable bottle for dispensing a fluid product including a body in which a container for packaging the product is formed, the bottle including a device for dispensing the packaged product, which is mounted in a sealed manner on the body, the bottle being equipped with a valve for refilling the container arranged to enable a product source to be placed in communication with the container in order to refill the latter, the valve including a passage for communication between the source and the container, the passage having a seat equipped with a valve element that is mobile with respect to the seat between a closed position and a open position, the valve element being arranged so as to be mobile between its closed and open positions under the effect of gravity by the positioning of the bottle in an upright position and in an overturned position, respectively.

Abstract: A fillable bottle for dispensing a fluid product provided with a relief valve for filling the reservoir and putting a source of product into communication with the reservoir for filling, the relief valve including a passage for communication between the source and the reservoir, the passage having a seat provided with a valve which is mobile relative to the seat between a sealed closed position and an open position of the passage, the valve being mobile between its closed and open positions under the effect of the gravity induced by the positioning of the bottle respectively in an upright position and in a turned-over position, the bottle including at least one bell in the reservoir, the bell being in communication with the reservoir in the upright position and isolated from the reservoir in the turned-over position in order to not be filled by the product coming from the source.

Abstract: A refillable bottle for dispensing a fluid product including a body in which a reservoir designed for conditioning the product is formed, the bottle including a dispensing device of the conditioned product that is mounted sealed on the body, the bottle being fitted with a reservoir filling valve arranged to enable communication of a product source with the reservoir to refill it, the valve including a communication passage between the source and the reservoir, the passage having a seating fitted with a check valve that is free to move relative to the seating between a sealed closed position and an open position of the passage, the bottle including a device for locking the check valve in the closed position, the device being arranged to be deactivated leaving the check valve in the closed position to release subsequent displacement of the check valve into the open position.

Abstract: A dispensing head for a system for dispensing a pressurized product, the head including a body having a mounting shaft for the head on a tube for supplying the pressurized product and a channel for dispensing the product between the shaft and an orifice for dispensing the product, the dispensing orifice being formed between two longitudinal walls, upper and lower, respectively, which are connected on either side, respectively, by a lateral wall of which the transverse dimension is smaller than the longitudinal dimension of the longitudinal walls, and each of the lateral walls has a projection that extends between the longitudinal walls, at least the walls of the dispensing orifice including an antimicrobial agent for the product to be dispensed.

Abstract: A method of dispensing a fluid product by using a dispensing bottle which includes a rigid body in which a reservoir for packaging the fluid product is formed and a device for taking off the packaged fluid product that is mounted sealingly on the body, the body also being equipped with a valve for filling the reservoir, the method, prior to the initial filling of the reservoir with fluid product, making provision for putting the empty reservoir in communication with an air suction device and activating the device in order to create a negative pressure inside the reservoir; subsequently effecting the initial filling of the reservoir by putting a product source in sealed communication with the reservoir by means of the valve; dispensing the packaged fluid product by actuating the take-off device.

Abstract: A bottle for dispensing a fluid product including a body in which a container intended for packaging the product is formed, the bottle also including an extraction device equipped with a pushbutton reversibly movable over a stroke for actuation of the device between a resting position and a depressed position in which the dispensing orifice is in communication with the container via the device, the body being equipped with a valve for filling the container by suction of the product contained in a product source, an upper wall being integrated in the body by way of a sealed connection that can be destroyed manually, the extraction device being mounted in the body with the pushbutton held in the depressed position on the upper wall so as to place the connection in communication with the container.

Abstract: A push button for a pressurised-product dispensing system, including an actuation body having an orifice for ejecting the product, a needle closing off the ejection orifice and a sleeve having a mounting well, the body being mounted to slide about the sleeve between high and low positions, forming between them a sealed space for conveying the product, the needle being associated with the sleeve by a link rotatably mounted on the sleeve to actuate the reversible movement of the needle between a closure position—or respectively an open position—of the ejection orifice when the body is in the high position—or respectively in the low position—, the needle provided with geometric means that interact with the body to exert a force holding the needle in a mounting position in which the needle projects from the body to enable the link to be associated with the needle.

Abstract: A system and bottle for dispensing a fluid product including a device for sampling the product under pressure, the device having a body incorporating a piston for dispensing which is in communication with a plunger tube, the body being provided with a vent hole which is arranged in order to make it possible to offset the volume of product distributed with air, the system further including a tube cover surrounding the plunger tube over at least one portion of its length, the tube cover being associated to the body with a bushing which has an exterior surface around which the upper end of the tube cover is arranged and an interior surface wherein the body is mounted, the interior surface having an orifice which is in communication with the vent hole, the orifice emerging into the interior surface above the exterior surface.

Abstract: A pushbutton for a system for dispensing a pressurized substance, the pushbutton including a body having a housing provided with an anvil around which a spray nozzle is mounted so as to form a substance dispensing path between the housing and a swirl array including a swirl chamber provided with a dispensing port as well as at least one supply duct for the chamber, the swirl chamber being defined by a side surface having a frusto-conical shape relative to which the supply duct(s) extend(s) in a transverse plane, the side surface tapering from an upstream end into which the downstream end of the supply duct(s) tangentially extends, to a downstream supply opening of the dispensing port, the dispensing port having an outlet size that is equal to the internal size of the downstream opening.
