A system for conserving a liquid substance (L) in a flexible receptacle ( ), the substance being liable to be degraded and/or contaminated on contact with ambient air. The system includes a solid insert ( ) whose outer envelope substantially matches the inside shape of the receptacle ( ) in which the insert is immersed at least in part. The insert has bactericidal and/or chemical, especially antioxidant, activity and provides protective treatment by making contact with substance (L) over a large interchange area.

System for preserving a liquid substance in a flexible container

The invention provides a dispenser for dispensing liquids from a receptacle, the dispenser having a cylindrical and conical body containing a measuring chamber closed at its bottom end by an admission valve and at its top end by a piston provided with a delivery valve and a delivery tube capped by a pushbutton, the body being the result of assembling together two independent elements: a top element carrying the piston and provided with a cylindrical skirt; and a bottom element provided with a sleeve for co-operating with the skirt by leaktight radial clamping so as to define the wall of the measuring chamber, the bottom element being provided with a bushing extending the sleeve coaxially downwards and engaged with leaktight radial clamping inside the neck of the receptacle.

Liquid dispenser having a two-part body

An endpiece for dispensing liquid pharmaceuticals contained in a receptacle, the endpiece being of the type comprising a tubular element ( ) provided at a free first end ( ) with a spray nozzle ( ) and at its second end ( ) with a rotary coupling ( ) providing a connection with the internal delivery duct ( ) of a pushbutton ( ) for fitting onto the top of a tapping member mounted on said receptacle, said rotary coupling ( ) being constituted by a core having a cylindrical cavity ( ) fitted to said pushbutton ( ) in communication with the internal delivery duct ( ) and in which the second end ( ) of the tubular element ( ) is engaged in touching and rotary manner, which second end is provided with means for opening said duct ( ), the endpiece being characterized in that said cylindrical cavity ( ) contains an axial rod ( ) secured to the pushbutton ( ) for being engaged inside the second end ( ) of said tubular element ( ) while leaving an intermediate space ( ) through which the pharmaceutical is transferred.

End cap for dispensing and spraying liquid pharmaceutical products

A liquid dispenser of the type comprising a tank (R) fitted with liquid extractor means (P) suitable for being actuated by axial displacement of the tank relative to a delivery tube (T) having a portion that projects outwards, the dispenser being characterized in that it comprises firstly a discharge duct ( ) connected in leakproof manner to the outer portion of the delivery tube (T) and passing through an endpiece ( ) connected rigidly to a housing (B) containing the tank (R), and secondly at least one side knob ( ) engaging the tank or the delivery tube and carrying a cam ( ) designed to co-operate in sliding contact with at least one sloping wall ( ) secured to said endpiece ( ) in such a manner that substantially radial thrust on said knob ( ) is transformed into axial displacement of the tube (T) relative to the tank (R), thereby causing the liquid to be dispensed.

Liquid sprayer

The invention relates to a packaging and bactericidal treatment device for contact lenses (L), said device being characterized in that it comprises: firstly a housing (,) provided with at least one cavity (,) receiving a support element (,) which has bactericidal action and whose outside face (,) has curvature matching the curvature of the contact lenses (L); and secondly, at least one lid (,) designed to cover said cavity (,) and whose inside face is provided with at least one socket (,) which is suitable for being engaged in guided manner into said cavity (,), and which receives a wedge element (,) having bactericidal action and whose outside face (,) has curvature complementary to the curvature of the support element (,) so that it protects and/or decontaminates a contact lens (L) by holding it stationary in said cavity (,) between said support element (,) and said wedge element (,).

Device for packaging and treating bactericide for contact lenses

Nasal applicator

A dispenser for substances packaged in the form of a liquid, cream, or gel, and particularly intended for cosmetic, dermatological, pharmaceutical, ophthalmic, or perfumery applications. The dispenser includes a tank (,) containing the substance (,) and is connected at one of its ends to a head provided with a pump (,) fitted with a fixing collar (,) and with a controlled shutter device for the vent (,) formed on the body (,) of the pump (,). The shutter device includes an air-permeable diffuser element (,) containing non-migratory agents for bacteriological and/or chemical treatment of air by contact. The diffuser element (,) is engaged on the pump body (,) and held by leakproof peripheral radial clamping of at least one annular zone, and by its top portion being engaged in the fixing collar.

Dispenser for liquid, cream or gel with a filter

The invention relates to an endpiece for dispensing and/or measuring out liquid pharmaceutical substances, the endpiece comprising a cylindro-conical body (,) fitted with a bottom base (,) for receiving thrust and for coupling to a tank capable of being put under pressure, and an axial ejection duct (,) containing a central core (,) and communicating firstly at its top end with a spray nozzle, and secondly at its bottom end with the tank, it is characterized in that the top end of the ejection duct (,) is closed in temporary and leakproof manner by a wall (,) which is secured to the top portion (,) of the body (,) and which extends perpendicularly to the duct, the wall being movable in reversible manner under drive from the substance, said wall being provided with a central orifice (,) capable of being closed in the closed position by a stud (,) secured to the core (,) being forced thereagainst, the periphery of the wall being attached to said body (,) via an elastically deformable link element (,) enabling the wall (,) to move in axial translation under pressure.

Sprayer nozzle with closing membrane

Antibacterial device for spraying a liquid

A device for packaging and dispensing a sterile liquid product. The device comprises a reservoir on which a nozzle is mounted. The nozzle is provided with an inner conduit which has an upstream end communicating with the reservoir and a downstream end opening to the outside via an evacuation orifice. The inner conduit is at last partially obturated by an insert of selective porosity which allows both a metered flow of the product to the outside and a filtration of air sucked towards the inside, stopping biological polluting and/or contaminating agents.

Device for packaging and dispensing sterile liquid products

Nozzle for dispensing a liquid or pasty material

A bottle for dispensing a liquid particularly intended for cosmetic, dermatological, or pharmaceutical applications, or any perfume product. An opening of the bottle is connected to a dispensing head provided with an airless pump, with a valve and with a cap. All or some of the walls of the bottle are made of a plastic having a very high air permeability so as to allow air to pass through the walls of the bottle.
