Abstract: A pump for dispensing a liquid product, including a pump body and a dispensing head manually movable on the latter, the head including a cylinder forming a dosage chamber of the pump, slidingly mounted in the pump body, and a channel allowing the passage of the product or air from the dosage chamber towards an ejection orifice. The rod includes means for airtightly sealing the channel consisting of a peripheral shoulder capable of coming to a rest against a complementary sealing seat arranged in the cylinder, the opening of the channel being performed by separating the sealing seat from the cylinder opposite the shoulder of the rod after the rod reaching its stop early during the axial movement of the cylinder in the pump body.

Abstract: A device for dispensing and receiving a liquid or semi-liquid product via a metering chamber of a pump body. The device includes a piston which is fixably mounted in the pump body and is provided with an end sealingly engaged into the chamber. The piston end is provided with an elastically deformable membrane put thereon. The membrane includes a transversal wall forming an input check valve which is provided with a central supply orifice sealingly closable by a protruded element forming the check valve seat on the end of the piston. The membrane includes a fixing cylindrical skirt which is provided with at least one sealing peripheral lip slidingly contacting the internal wall of the chamber. The skirt forms a valve when it is deformed by contact with a projection bearing by the internal wall of the chamber in such a way that the air compressed by the piston is released into the chamber by the pump priming.

Abstract: The invention concerns a device for locking an axially mobile actuating and freely rotating head of a pump whereof the body is mounted on the neck of a reservoir of liquid product via a connecting socket. The invention is characterized in that it comprises an intercalated ring mounted on top of the pump body and whereof the inner side wall is provided with at least one longitudinal guiding groove capable of receiving, through rotation of the head, at least one rib bone by an inner coaxial sleeve integral with the head.

Abstract: The invention is a pump for dispensing liquid or semi-liquid product, designed and intended to be used in particular in the pharmaceutical or cosmetic field. The pump has a needle valve and a dispensing head manually movable on a pump housing between an inactive position and a dispensing position. The head includes a first cylinder forming a metering chamber for the pump, which draws in fluid from a container's reservoir by an intake tube and a check valve. A piston sealingly secured to the metering chamber pushes fluid through a passage into a second dosage chamber that is sealed from the dispensing orifice by a biased needle valve that is biased by a spring that is sealingly isolated from the second dosage chamber, the chamber that holds the elastic spring has a conduit that allows a user to test and verify that the second dosage chamber does not leak.

Abstract: Dispensing member for a fluid product comprising a post and a spray nozzle, said post having an abutment surface and said spray nozzle comprising a transverse wall, an outlet orifice extending across said transverse wall, said outlet orifice being delimited by a lateral surface, at least one duct for supplying the fluid product to the outlet orifice, the said supply duct being delimited by the transverse wall and the abutment surface, being supplied with fluid product via a supply channel, emerging substantially tangentially relative to the lateral surface of the outlet orifice, and forming the only fluidic communication between the supply channel and the outlet orifice.

Abstract: Manual spraying device including a push-button that can be actuated manually, the push-button including a spray nozzle, the spray nozzle having an inner chamber adapted to receive a non-gaseous fluid product under pressure and delimited towards the outside by a perforated front wall, a reservoir for the fluid product to be sprayed, and a dispensing device that can be mechanically actuated by the push-button and adapted to transfer the fluid product from the reservoir to the inner chamber of the nozzle, the front wall having a plurality of calibrated holes, each having a diameter of between 1 and 100 ?m, the diameter of each hole not differing from a mean of the diameters of the various holes by more than 20%.

Abstract: A device for encasing a system for dispensing a liquid product, provided mainly with an evacuation conduit, the downstream end of which opens to the outside, characterized in that it includes, on the one hand, a compartment respectively delimited by a back wall and a front wall with an outlet orifice in it and, on the other hand, at least one elastic return element supported by the said system on the side opposite the downstream end that can retract such as to allow the said system to be inserted in the said compartment and can then rest against the back wall to as to insert and maintain the end of the said conduit in the outlet orifice.

Abstract: The invention concerns a pump sprayer equipped with a projecting side nozzle. The nozzle is defined at the end of a rectilinear element attached to the pushbutton and said element is force-mounted in a cavity of the push-button, which is of sufficient depth to enable a depression of selected length, determining the length of the projecting part of said element.

Abstract: A device for tamper protecting and authenticating a liquid product distributor including a container with a cylindrical neck with a seal engaged therein, further including an indicator element with a collar which is elastically inwardly collapsible and whose largest diameter is greater that the neck internal diameter and which is removably disposed on the lower part of the seal and is trapped in the container after a forced penetration through the neck. The indicator element includes a sleeve in which the lower part of the seal is radially clamped.

Abstract: An airless dispensing pump for liquid products including a push button with a spray nozzle which communicates with a network of channels that is provided locally on the wall of an internal truncated-cone-shaped bore, and a housing. An upper part of the housing includes a dosing cell having an elastically-deformable wall, which is equipped with an intake valve and topped with a rigid collar for fixing same inside the bore of the aforementioned button. Moreover, the outer periphery of the collar has an inclined face which defines a swirl chamber opposite the above-mentioned network, while the inner periphery thereof is quipped with a passage to the chamber.

Abstract: The invention relates to a distributor for a liquid product, in particular, a miniature spray, having a reduced number of parts. The distributor includes a reservoir and a manual action pump, provided with a hollow push-button, arranged such as to slide in a sealed manner with relation to the exterior of a tubular neck of the pump body, defining a dosing chamber, extending at least partly into the interior of the push-button.

Abstract: A liquid product dispenser includes a reservoir and a pump. The pump body includes an outer portion forming a sealing closure between the pump body and the reservoir nozzle and the pump body includes an annular projection extending inwards, molded in one single piece, while the piston includes an annular stop co-operating with the annular projection to define a released position of the piston.

Abstract: An application device for a liquid product, contained in a reservoir bottle having a lid for closing the opening of the bottle, through which at least one capillary migration channel for the liquid product passes towards a wetable surface on contact therewith is provided. Several similar capillary channels are preferably provided, which can alternatively function as openings for the entry of air through the lid. One of the ends of each channel opens outside the lid. The other end opens in a collector tube for the liquid product, contained in the bottle. The collector tube is embodied to hold a fixed amount of liquid product against gravity by capillary action, until the above is drawn off by capillary migration through the lid channels.
