  • the purpose of the present invention is, in particular to propose a dispensing head which can be actuated by pressing on any point of its external surface related.
  • This dispenser can be used in different fields of application and serve for the distribution of cosmetic products (hairspray, deodorant, foam hair, body milk, depilatory foam, liquid foundation, sun milk, gel styling, self-foaming shaving gel) or dermopharmaceuticals (insect repellent, pain reliever or anti-inflammatory), household products, paint, etc., as a liquid, gel, spray or foam.
  • Such dispensers comprise, in known manner, a reservoir containing the product and a propellant, fitted with a distribution valve fitted with a rod control, a dispensing head comprising a movable part provided with a connection means for communicating the mobile part with the valve and order the opening thereof.
  • the connection means is clean to act on the actuating means of the valve.
  • the mobile part includes plus a conduit passing through the connection means and connecting one end from the valve stem to a dispensing orifice provided in the movable part.
  • the head further comprises a fixed part such as a retaining band, capable of being fixed on the tank and provided for the maintenance of the mobile part.
  • the moving parts and fixed are linked together by elastic connecting means.
  • connection means is constituted by a pin integral with the movable part, and able to cooperate with the valve stem, when using a valve with emerging stem.
  • a dispenser has been described in document FR-A-2 718 720, at name of the applicant. This comprising a product reservoir under pressure fitted with a side tilt valve, and surmounted by a distribution.
  • the dispensing head of this dispenser is made in one piece. She has a push button provided with the dispensing orifice, connected to a hoop of fixing, by a set of flexible tabs. Thus, a reentrant zone is formed between the mobile part and the fixed part.
  • the mobile part has a extended support surface for actuating a distribution valve, of the type tilting sideways, pressing any point on the surface of the mobile part.
  • the above dispensing head may have the following disadvantages: when the user presses with his finger on the part mobile, it pivots towards the tank, and the finger can undergo a pinching between the fixed hoop and the movable part.
  • you rinse the dispensing head for example under the tap, you trap a considerable amount of water, this amount of water flowing, so untimely, when changing the inclination of the dispenser.
  • a distribution head comprising a movable part carrying a porous applicator member, and a fixed part, such as a fixing band, a flexible connection between the mobile and fixed parts being produced by a flexible veil, continuous, thin.
  • This distribution head is made up of two parts and has an application member.
  • the dispenser is supported on the surface, which causes opening the valve and dispensing the product.
  • document EP-A-0 669 268, in the name of the applicant, describes, in particular with reference to FIGS. 4 and 5, a dispensing head mounted on a product tank.
  • This head includes a fixing band, snapped onto the tank and a push button fitted with a dispensing nozzle.
  • the push button is linked to the hoop by means of an annular junction zone made in elastomer.
  • the push button has mobility by relative to the tank, sufficient to activate the dispensing valve.
  • the object of the present invention is to perfect distributors of the kind of those described above by improving their comfort of use, in particular, by recommending a bearing surface, in order to trigger the distribution of the product, of a widened extent so that the distribution of the product can be performed by pressing on substantially any point on its surface.
  • the invention provides a dispensing head with a smooth surface that does not have no discontinuity, in particular no cutting line or re-entrant part, between mobile actuating means and head fixing means on the tank. Thanks to the invention, the entire external surface of the head can serve of product sampling area. In addition, the whole head can be rinsed under the tap, without risk of trapping water in the space defined by the fixed and moving parts of the head.
  • the head can be made of a non-slip material, allowing the dispenser to be used of the invention, with wet hands.
  • the actuation and distribution means and the means of connection form a single piece, made of elastomeric material thermoplastic, said valve being operable by an applied pressure at any point on an external surface defined by the means actuation and distribution and connecting means.
  • the elastomeric material has a Shore A hardness included between 30 and 70.
  • This material is advantageously chosen from silicones, natural or synthetic rubbers, nitrile rubbers, polyurethanes, blends of polypropylene and styrene block copolymers - butadiene - styrene, polypropylene and styrene-ethylene block copolymers - butylene - styrene, polypropylene and block copolymers ethylene - propylene - diene.
  • the attachment means consist of a cylindrical hoop forming a single piece with the flexible connection means and the actuation and distribution means, the external surface of the head having substantially no reentrant part.
  • the entire dispensing head is made of material elastomeric.
  • the attachment means advantageously include, a cylindrical portion of greater thickness than that of the means of link.
  • the attachment means are constituted by a cylindrical hoop, made of rigid or semi-rigid thermoplastic material, this hoop, on the one hand, carrying the connecting means and the means actuation and distribution and on the other hand, clinging to said reservoir, the external surface of the head having substantially no reentrant part.
  • a cylindrical hoop made of rigid or semi-rigid thermoplastic material
  • this hoop on the one hand, carrying the connecting means and the means actuation and distribution and on the other hand, clinging to said reservoir, the external surface of the head having substantially no reentrant part.
  • bonding or thermal welding of the respective parts.
  • it is more advantageous to make this connection during molding of the head for example by a technique of bi-injection of the material rigid thermoplastic to form the hoop, and elastomeric material to train the means of actuation and distribution as well as the means of flexible binding.
  • the connecting means and the actuation and distribution means have a general form of dome.
  • the dome thus formed comprises, the dispensing orifice which is connected by the distribution channel to the valve stem.
  • This channel has advantageously a terminal part in the form of a pawn, capable of fitting onto said valve stem.
  • the counter consists of a relatively wall thick, required to provide shape stability necessary for actuation of the valve.
  • the constitution of the dispensing orifice depends on the nature of the product to be distribute and the desired form of distribution. So, to dispense a dose a relatively viscous product such as a shampoo, a styling gel or a cream, a simple orifice can be produced by molding. When we want distribute a relatively liquid product, such as hair spray, under form of spraying into fine droplets (spray), it is desirable to have a nozzle attached to the end of the distribution channel. So you can use commercial vortex or semi-vortex nozzles, allowing to obtain an improved spray, the droplet size of which is much smaller than the droplet size produced by a non-vortex nozzle.
  • a foaming liquid in the form of foam for example example a shaving foam or a styling foam
  • a grid or any other attached device it is possible, in end of the distribution channel, a grid or any other attached device, to create the desired foam texture.
