Definitions

• the present invention relates to a fluid reservoir comprising a bottom and an opening.
• This reservoir is intended to be associated with a dispensing member, such as a pump or a valve, to form a fluid dispenser.
• the present invention also relates to a fluid dispenser comprising a reservoir according to the invention.
• the preferred fields of application of the present invention are those of perfumery, cosmetics or even pharmacy.
• the documents FR358354 and FR358564 describe bottles with a neck in which a ball is hermetically engaged. Using a pusher in the form of a tube, the ball can be pushed to make it fall by gravity to the bottom of the bottle. These bottles are not suitable for mounting a pump or a valve and thus constitute a fluid dispenser.
• the present invention aims to overcome the aforementioned drawbacks of the prior art by defining a removable tank of simple structure which is initially sealed by a sealing ball and whose opening can be released simply by the establishment of a dispensing member, such as a pump, of standard design.
• Another object of the present invention is to use a single push member to both release the sealing ball from the opening of the tank and seal between the reservoir and the dispenser member.
• the present invention provides a fluid reservoir comprising a bottom and a conduit defining an opening, a sealing ball being engaged in the conduit so as to seal the opening, the ball being movable by a thrust member external so as to drop the ball by gravity to the bottom of the tank so that the opening is thus released,
• the conduit is connected to a dip tube which extends to near the bottom of the reservoir, the conduit having a diameter which is smaller than that of the dip tube, the ball being in sealed engagement with the conduit prior to to be pushed into the dip tube in which it falls freely to the bottom of the tank.
• the dip tube is thus integrated in the tank, so that the pump or valve that is mounted on it does not need to have a dip tube. It is also easier to dislodge the ball from the conduit with the inlet of the pump or valve, which is hard, rather than with a dip tube, which is very often flexible.
• the sealing ball is not a ball valve, and serves only to seal or initially seal the opening of the tank. Once it has been pushed by the external thrust member, it falls freely into the tank and no longer fulfills any function, except to inform the user that the connection of the dispensing member to the tank has been correctly performed. . For this, it must of course that the tank is transparent or at least translucent.
• the ball is trapped in the plunger tube.
• the conduit and the plunger tube are integrally formed by an insert.
• the conduit may be considered as a local constriction or constriction of the dip tube located at the reservoir opening.
• the opening is formed by a conduit comprising a protruding internal sealing bead, the sealing ball being in sealed engagement in the conduit below the bead.
• the sealing bead is intended to come into pressed contact with an element of the dispensing member, such as for example the external thrust element.
• the ball may be placed above the bead.
• the opening is formed by a conduit comprising a protruding internal sealing bead, the ball being in sealing engagement with the protruding internal sealing bead.
• the ball may be disposed below or above the cord, or at the cord.
• the contact between the ball and the cord forms a sealed annular contact which can be added to the contact between the ball and the conduit.
• the reservoir comprises a reservoir body forming the bottom and an insert forming the conduit and the opening, the insert also forming a collar which extends radially outwardly from the conduit, the flange engaging the tank body.
• the ball can thus be pre-assembled in the conduit of the insert before returning and fixing the insert on the tank body.
• the fixing of the insert on the tank body can be carried out by any means, such as, for example, the snap-in seal, the waterproof-sealing plug, the welding, the gluing, etc.
• the tank can also be made in one piece.
• the present invention also defines a fluid dispenser comprising a pusher and a dispensing member, such as a pump, removably mounted on a reservoir as defined above, the dispensing member comprising a thrust member adapted to to be introduced into the opening of the tank to push the ball and make it fall to the bottom of the tank.

• the thrust member is formed by an inlet tube which communicates upstream with a chamber of the dispensing member, the inlet tube sealingly engaging in the opening tank to establish a communication between the tank and the chamber.
• the inlet tube serves a dual function, namely that of pushing the ball out of the conduit and that of sealing between the reservoir and the dispenser member. This seal can be improved by the presence of a sealing bead inside the conduit.
• the thrust member is formed by a dip tube which communicates upstream with a chamber of the dispensing member, the dip tube being connected to an inlet tube sealingly engaged in the opening the tank, thus establishing a communication between the tank and the chamber.
• the dip tube pushes the ball out of the conduit, and the inlet tube seals with the conduit.
• the plunger tube is made integrally with the inlet tube, so that the inlet tube can be considered as an integral part of the plunger tube. In this case, it can be considered that the plunger tube also performs a dual function, namely that of pushing the ball and that of sealing between the reservoir and the dispenser member.
• the dispenser comprises a holster which envelops the pusher, the dispenser member and a portion of the reservoir so that the holster is movable relative to the reservoir by displacement of the pusher with respect to the hinge member. distribution.
• the spirit of the invention lies in the fact of very simply sealing a reservoir, preferably removable, with the aid of a ball which is disengaged from the opening of the reservoir by a pushing member of a dispenser member (pump for example) and falls by gravity into the tank.
• the thrust element also fulfills a sealing function between the reservoir and the dispenser member.
• the presence of a dip tube integrated in the tank allows to use a dispensing member without a dip tube and to keep the ball captive of the dip tube once clear of the opening.
• the reservoir of the invention can be used with any standard or conventional pump since they all include an inlet tube that connects a pump or valve chamber through an inlet valve.

• the pusher comprises a dispensing orifice 51 which advantageously allows the fluid to be dispensed in spray form or spray form. By pressing on the pusher 5, the actuating rod 44 is moved, driving with it the piston 42, so as to reduce the useful volume of the pump chamber 40.
• the inlet valve 41 is then closed, and the Opening of the outlet valve 43 takes place when the pressure inside the pump chamber 40 reaches a predetermined threshold. From this moment, the fluid under pressure in the chamber 40 can flow through the actuating rod 44 to reach the dispensing orifice 51. As soon as the pressure on the pusher 5 is released, the actuating rod 44 returns to its rest position under the action of a return spring. The pump chamber 40 then increases in volume, the outlet valve 42 closes and the inlet valve opens to suck fluid from the reservoir through the plunger tube 46 and the open inlet valve 41. This is a quite conventional operation for a pump associated with a pusher in the fields of cosmetics, pharmacy or perfume.
