Definitions

• the present invention relates to a fluid dispenser comprising a fluid reservoir, a pump mounted on the reservoir and a pusher mounted on the pump for actuating it.
• a fluid dispenser comprising a fluid reservoir, a pump mounted on the reservoir and a pusher mounted on the pump for actuating it.
• dispensers comprising a fluid product applicator which is in direct communication with the fluid product stored in the reservoir.
• the applicator can be integral with the reservoir, or on the contrary a gripping member that can be detached or separated from the reservoir.
• the loading of the applicator fluid product can be done by turning or shaking the dispenser, or by suction, as for example in the document ...
• dispensers (applicator and pump) belong to distinct families and differentiated applications.
• the object of the present invention is to define a new type of fluid dispenser whose basic characteristics are those of a conventional pump and pusher dispenser. Another object of the present invention is to combine in a single distributor the advantages of the two types of distributors (applicator and pump). Yet another object of the present invention is to ensure a repetitive and controlled loading of a fluid applicator. Yet another object of the present invention is to combine the characteristic gestures of dispenser applicators and pump dispensers.
• the pusher comprises a base mounted fixedly on the pump and a gripping member removably mounted on the base, the body of gripper comprising a fluid product applicator, the gripping member defining a bearing surface on which can be axially pressed to drive the base in displacement and thus actuate the pump to charge the applicator fluid product.
• the dispenser of the invention is distinguished by the presence of the applicator which is integral with the pusher, itself incorporated into a gripping member.
• the present invention is distinguished by the presence of a pump for conveying the fluid to the applicator and a pusher on which the applicator of a fluid product is mounted.
• the user combines the two gestures, the two types of dispensers, namely the actuation of a pusher to dispense a dose of fluid and the use of the gripping member which is detached from the rest of the dispenser to be applied to an application surface such as skin, nails, hair, etc.
• the base comprises a receiving cup for the applicator, the cup forming a supply port connected to the pump.
• the receiving cup can be directly mounted on the actuating rod of the pump.
• the cup conforms to the shape of the applicator, and advantageously defines supply channels that extend radially outwardly from the supply port. This ensures that the entire dose dispensed by the pump reaches the fluid applicator, and this in a controlled manner, thanks to the presence of supply channels that extend in a specific direction.
• the gripping member is sealingly mounted on the base, advantageously by crushing a seal.
• the applicator is hermetically sealed inside its receiving cup.
• the gripping member is removably connected to the base by magnetic means. It is not necessary that the magnetic means be located on the base, but simply that the magnetic means allow a detachably connecting between the gripping member and the base.
• the magnetic means, as connecting means are particularly advantageous because they allow a repositioning of the gripping member on the base without having to exert a pressing force on the base. This avoids inadvertent or involuntary operation of the pump.
• the magnetic means allow a quasi-automatic and centered repositioning.
• the magnetic means because of the force of attraction exerted, allow the crushing of the seal which allows to hermetically isolate the applicator inside its receiving cup.
• the base slides, advantageously sealingly, in an axial guide sleeve integral with the reservoir. This ensures that there is no leakage of fluid inside the dispenser during its sliding movement inside the guide sleeve.
• a fluid return passageway connects the base to the reservoir.
• the fluid dispensed by the pump into the receiving cup returns to the reservoir, as soon as the applicator is filled or saturated with fluid.
• a user presses the pusher several times so as to dispense a very large quantity of fluid product.
• the excess fluid product injected into the receiving cup may thus be redirected towards the reservoir. This ensures that the applicator is always filled or impregnated with the same amount of fluid and avoids any risk of fluid leakage created by an overpressure inside the receiving cup.
• the gripping member comprises a gripping body in which a push button is movable back and forth, the applicator being integral in displacement of this push button, which is advantageously solicited by rest position by a return spring which acts between the gripping body and the push button.
• the applicator is connected to a mounting bracket which slides tightly in the gripping body, the pushbutton being engaged with this mounting bracket.
• the spirit of the present invention resides in the fact of associating a fluid applicator with a pusher serving to actuate a pump for charging the applicator, the pusher being part of a gripping member which the user can grasp for separate it from the remainder of the dispenser and bring the applicator into contact with an application surface such as the skin.
