Description

The invention relates to a refillable bottle dispensing a fluid, and an assembly comprising such a bottle and a product source for filling said bottle.

In particular, the refillable bottle allows the dispensing of a liquid product, for example a cosmetic care, makeup or perfume product, or a pharmaceutical product.

The refillable bottle comprises a body in which a product conditioning tank is formed, as well as a dispensing device of the packaged product which is sealingly mounted on said body. In particular, the dispensing device may comprise sampling means in the form of a manually operated pump which is fed with conditioned product, said pump being arranged to distribute the product under pressure, for example in the form of an aerosol . Alternatively, the dispensing device may comprise means for applying the product, for example in the form of a ball.

In an exemplary application, the refillable vials according to the invention allow the distribution of product samples, especially for a volume of packaged product in the reservoir which is between 1 and 10 ml. In particular, the samples thus distributed can allow a customer to test the product, the bottles then being called sample vials. Alternatively, the bottles can be called "bag" in that they can easily transport a reduced volume of product, as opposed to bottles of higher capacity which are usually heavy and bulky because affluent.

In these applications, for example for logistical, practical or environmental recycling reasons, it may be desirable to be able to recharge the reservoir product from a source of said product. Indeed, it is impractical for a user to fill the tank with using a small funnel and unecological to discard an empty flask to replace it with a full constituent refill.

Refillable bottles are already offered for sale, in which the body is equipped with a tank filling valve which is arranged to allow the communication of a product source with said tank for filling. In particular, the valve comprises a communication passage between the source and the reservoir, said passage having a seat equipped with a valve which is movable relative to said seat between a closed position and an open position of said passage.

To perform the filling, the prior art proposes to use a source bottle comprising a dispensing pump, the valve being moved by means of the nozzle of said pump. In particular, the valve is elastically constrained in the closed position and the sealing support of the nozzle on the valve allows the reversible opening of said valve and the actuation of the pump for injecting the source product into the reservoir through the valve . However, this embodiment poses sealing problems during filling, in particular because of the difficulty in properly positioning the nozzle in sealing engagement with the valve by exerting sufficient force to jointly cause the opening of the valve and the actuation of the valve. pump, especially since the pump must be actuated several times to inject a sufficient volume of product. The embodiment of FIGS. 13a to 14c disclosed in the patent application FR 2 802 447 describes a filling bottle according to the preamble of claim 1.

The invention aims to improve the prior art by providing in particular a refillable bottle whose actuation of the filling valve is made so as to make the sealing more reliable during filling, and with a gesture particularly easy and intuitive.

In the description, the terms of positioning in space are taken with reference to the straight position of the refillable bottle as shown in particular on the figures 3 , 4 and 9a .

In connection with the figures, described below a refillable bottle for containing a fluid for distribution. In particular examples, the product may be liquid, in particular a cosmetic care, make-up or perfume product, or a pharmaceutical product.

The refillable bottle comprises a body 1 in which a container 2 for packaging the product is formed. According to a particular application, the tank 2 may have a capacity of between 1 and 10 ml so as to allow the distribution of product samples.

In the embodiments shown, the body 1 is rigid, in particular having sufficient rigidity so that the volume of the reservoir 2 remains substantially constant, even if the internal pressure varies. The body 1 may be integral, for example produced by injection-blow molding or extrusion-blow molding, or in several parts injected and then assembled, for example by ultrasonic welding, or by laser, or by rotary friction, made of rigid plastic material, metal, for example aluminum, or glass.

The bottle comprises a device for dispensing the packaged product which is sealingly mounted in the body 1. In the embodiment shown, the dispensing device comprises a pump 3 manually actuated by means of a pushbutton 4, said pump being fed product through a dip tube 5 which is disposed in the tank 2.

However, the invention is not limited to a method of dispensing the product. In particular, other types of means for taking the product from the tank 2 can be envisaged. The dispensing device may also comprise means for applying the product, for example in the form of a ball.

The push button 4 comprises a dispensing orifice 6 and an upper zone allowing the user to exert a digital support on him in order to move the nozzle of the pump 3 on its supply stroke of said orifice in pressurized product. In the embodiment shown, the push button 4 is equipped with a spray nozzle which is arranged to radially distribute an aerosol of the product through the dispensing orifice 6. However, especially for a nasal spraying nozzle, the push button 4 may allow axial distribution of the product. Alternatively, the product can be dispensed in the form of a hazelnut or a web.

The bottle is equipped with a filling valve 7 of the tank 2 which is arranged to allow the communication of a source 8 of product with said tank for filling. In connection with the figures, the body 1 has an upper opening 1a in which the pump 3 is mounted by means of a collar assembly 9, and a lower opening 1b which is equipped with the filling valve 7.

The lower opening 1b is formed in the bottom of the body 1 and the filling valve 7 comprises a skirt 10 which extends axially peripherally under said opening. Thus, a communication passage 11 is formed between the source 8 of product and the reservoir 2, said passage extending in the skirt 10.

In the figures, the skirt 10 is attached under the body 1, but it could also be formed in one piece with said body. More specifically, the filling valve 7 comprises a hollow housing 10a whose upper wall 10b is fitted into the lower opening 1b, the skirt 10 being formed under said upper wall to extend outside the body 1.

The passage 11 of communication has a seat 12 equipped with a valve 13 which is movable relative to said seat between a sealed position and an open position of said passage. In particular, the seat 12 can be formed on the inner periphery of the skirt 10.

The bottle comprises a locking device of the valve 13 in the closed position which makes it possible to prevent the displacement of said valve in the open position, in particular between two fillings, in order to prevent product leakage through the valve 7. in addition, the locking device is arranged to be deactivated leaving the valve 13 in the closed position to release the subsequent movement of said valve in the open position.

Thus, the gesture of unlocking the valve 13 is dissociated from that of its opening to perform the filling, in particular to be able to to overcome the constraints of unlocking to make the sealing more reliable during filling. In particular, in the unlocked state, the displacement of the valve 13 between its closed and open positions is free, that is to say, in particular by not being constrained by an added means, in order to limit the necessary effort. at the opening of the valve 13.

In the embodiments shown, the valve 13 is arranged to be movable between its closing and opening positions under the effect of the gravity which is induced by the positioning of the refillable bottle respectively in a straight position ( figure 9a ) and in an inverted position ( figure 9b ). Thus, after unlocking the valve 13, the filling is effected by simple gravitational flow of the product and a transfer of air in the opposite direction through the passage 11 between the source 8 of product and the reservoir 2 to fill, the filling can be achieved by a simple gesture mounting the refillable bottle in the upright position on the source 8 of product followed by a reversal of the whole refillable bottle - source 8 of product.

In particular, the upright position corresponds to the normal position of use of the refillable bottle in which the push button 4 is arranged upwards. Alternatively, the refillable bottle in the upright position can be oriented differently, provided that the valve 13 is there in the closed position under the effect of gravity.

The refillable bottle in the upright position can be mounted and connected to the source 8 of product without inducing product transfer, in particular because of the lack of pressurization of said product. Then, the returned position corresponds to a rotation of the refillable bottle assembly - source 8 of product for disposing said source above the tank 2 to induce filling by flow. On the figures 9 , the rotation is 180 ° but it could have a different angle, provided it is sufficient to open the valve 13 under the effect of gravity.

After filling, the refillable bottle - source 8 of product is returned to the initial position before disconnecting said bottle for later use. In particular, this reversal induces the closing of the valve 13 under the effect of gravity.

According to another embodiment, after unlocking the valve 13, the filling of the bottle can be achieved by suction, for example by providing that the reservoir 2 has an air depression which is sufficient to actuate the opening of the valve 13 and the transfer of the product from source 8 of product.

According to another embodiment, after unlocking the valve 13, the filling of the bottle can be performed by injection, for example by providing for opening the valve 13 by placing on it a nozzle of a source bottle, the effort necessary to said support being then reduced because of the freedom of movement of the valve 13 unlocked between its closed and open positions.

In relation with the figures, the valve 13 comprises an annular bearing surface 14 which, in the closed position, comes into sealing engagement with the seat 12 which has a complementary bearing surface ( figure 9a ), said range in the open position being disposed at a distance from said complementary bearing ( figure 9b ). To improve the tightness in the closed position, the bearing surface 14 and the complementary bearing surface of the seat 12 may be frustoconical.

Furthermore, the valve 13 is equipped with a ballast 16 whose weight is sufficient to move said valve between its open and closed positions. In particular, the ballast 16 induces a tight plating force of the annular bearing surface 14 on the seat 12 and ensures the detachment of said bearing during the overturning.

In the embodiment shown, the valve 13 is movable in axial translation between its closed and open positions. Alternatively, possibly complementary, the valve 13 can be movable between its closing and opening positions by deformation induced by gravity, in particular by deformation of the annular bearing surface 14 on the seat 12.

In the figures, the valve 13 comprises an upper cage 17 having a lower bead on which the annular bearing surface 14 is formed, an attached weight 16, for example based on metal, being fixed in said cage. Alternatively, the ballast 16 may be integrated with the valve 13, in particular by making said valve based on a material of high density, for example a polymer loaded with metal particles or directly metal material.

The valve 13 comprises a lower rod 18 which extends under the cage 17, said rod being slidably mounted in a tube 19 integral with the skirt 10, said rod and said tube being arranged to define the end of travel of the valve 13 in the open position. In the embodiment shown, the upper end of the rod 18 is snapped into a lower hole of the cage 17, but said rod could be formed integrally with said cage.

Furthermore, the cage 17 is equipped with a lid 20 which makes it possible to isolate the ballast 16 from contact with the packaged product in the tank 2. In addition, the lid 20 forms a bell 21 which is integral with the valve 13 while being disposed in the tank 2, said bell being arranged for, in the upright position ( figure 9a ), be in communication with said reservoir and, in the inverted position ( figure 9b ), be isolated from said tank so as not to be filled with the product from source 8.

To do this, the cover 20 has an axial peripheral wall 20a which extends on a radial bottom wall, the bell 21 being formed inside said walls to form a retention volume which is open at the top. In particular, the walls 20a are arranged so that the retention volume in the inverted position is not in flow communication with the passage 11.

Thus, during the emptying of the tank 2, a volume of air is formed which, during the overturning, is retained in the bell 21 to be released into said tank during the return to the upright position, which makes it possible to guarantee the presence of a sky of air in said tank after filling. In particular, the air space allows expansion of the product during a rise in temperature without exceeding the permissible pressure in the tank 2, for example of the order of 5 bars. This embodiment is particularly advantageous when the product contains alcohol, for example by providing that the retention volume of the bell 21 is of the order of 5 to 7% of the conditioning volume of the tank 2.

The tube 19 is mounted in the skirt 10 via at least one rib 22. In connection with the figures 5 three ribs 22 are provided to form three openings in the passage 11 of communication. The ribs 22 are arranged to promote a parietal flow of the product in the communication passage 11, in particular by being connected inside the skirt 10 over substantially its entire axial dimension and each having a free edge which converges towards a radial base connected to the periphery of the tube 19.

Thus, during the return of the refillable bottle in the upright position at the end of filling, the flow in the source 8 of the product contained in the passage 11 of communication is facilitated to prevent product leakage under the refillable bottle upon its disconnection. .

Similarly, the filling valve 7 may have surfaces whose hydrophobicity is arranged to promote the flow of the product in the passage 11 of communication. In particular, the inside of the housing 10a can be rendered hydrophobic, for example by fluorinated plasma treatment, by dipping in a silicone bath or by producing said casing of hydrophobic material such as PTFE.

The source 8 of product comprises a reservoir 23 of product, in particular formed inside a bottle of capacity greater than that of the bottle fillable. According to another embodiment, the source reservoir 23 is formed inside a flexible bag which can be filled with product without air or gas for the proper preservation of said product.

The source reservoir 23 is equipped with a bushing 24 which is arranged to allow the sealing connection of the filling valve 7 to said source reservoir by putting the passage 11 in communication with it. In addition, the filling valve 7 is equipped with a device for sealing the bottle on the source 8 of the product, the sleeve 24 being equipped with a connection device which is complementary to that of the filling valve 7.

In relation to Figures 1 to 3 and 5 to 9 , the locking device of the valve 13 is arranged to be deactivated by sealing connection of the bottle to the source 8 of product. In particular, the sleeve 24 comprises means for deactivating the locking device of the valve 13 by sealing connection of the bottle on the source 8 of product. In addition, the locking device is arranged to be reactivated when disconnecting the refillable bottle.

In relation to figures 6 , the sleeve 24 comprises a collar 25 for mounting on the neck of the source bottle 8, said collar being fixed on said neck by means of a collar 27. The collar 25 has an upper opening which is surmounted by a sleeve 28 extending axially in a peripheral manner. Advantageously, the bushing 24 is devoid of means for pressurizing the filling product. Thus, the bottle 8 can not be diverted from its source role since without propellant or internal pressure.

The skirt 10 of the filling valve 7 is arranged to slide axially with respect to the sleeve 28 of the sleeve 24. In particular, the skirt 10 and the sleeve 28 are annular, the outer diameter of the skirt 10 being slightly smaller than the inside diameter. of the sleeve 28 to allow axial mounting without play of the refillable bottle on the source 8 of product. In addition, the skirt 10 may be slightly frustoconical and have a chamfer lower to ensure a radial clamping during axial sliding of said skirt in the sleeve 28.

In the embodiment shown, the connecting devices comprise pins 30 integral with the skirt 10 or the sleeve 28 which are intended to cooperate with ramps 31 secured to the sleeve 28 or the skirt 10 to allow mounting and immobilization of the refillable bottle in position connected to the source reservoir 23. In the figures, a set of two diametrically opposed lugs 30 is formed around the skirt 10 to cooperate with a set of two ramps 31 formed in the sleeve 28, said lugs having a lower chamfer facilitating their introduction into the ramps 31.

The ramps 31 comprise an axial portion 31a of sliding lugs 30 and a peripheral portion 31b of rotation of said lugs. Thus, a bayonet-type gesture is obtained for sealingly connecting the refillable bottle to the product source 8, namely an axial mounting of the filling valve 7 in the sleeve 24 followed by a relative rotation of immobilization of the bottle. refillable in position connected to the source 8 of product, the unlocking of the valve 13 being thus made by relative rotation between said bottle and the source 8 of product.

In the figures, the peripheral portions 31b comprise a boss 32 for locking the pins 30 in the connected position. In addition, the sleeve 28 comprises lights 33 which are arranged under the bosses 32 to facilitate their deformation during locking.

An annular seal 34a is interposed between a radial bearing surface 28a of the sleeve 28 and the neck of the source 8 of product and, during assembly of the refillable bottle on the source 8 of product, the lower end of the skirt 10 comes in axial support on another annular seal 34b which is disposed on said radial bearing. Thus, by compression of the seals 34a, 34b, it ensures the sealing of the connection of the passage 11 through which the product flows during filling. To realize a locking device which is deactivated by connecting the refillable bottle to the product source 8, the rod 18 comprises a raised profile and the tube 19 comprises a low reach 19a and a high reach 19b. In the figures, the profile is formed by two projecting notches 35 on either side of the rod 18, the lower surface of the tube 19 comprising two diametrical notches which are angularly offset by 90 ° to form the respectively low and high bearings 19a 19b.

The rod 18 and the tube 19 are relatively movable between a locked position in which the profile 35 is arranged on the lower bearing 19a to maintain the valve 13 in the closed position ( figures 7 ) and a free position in which the profile 35 can slide towards the high reach 19b to allow the displacement of the valve 13 in the open position ( figures 8 ). In addition, this embodiment makes it possible to define the end of displacement travel of the valve 13 in the open position by axial support of the notches 35 on the high reach 19b.

To make the unlocking movement during the connection, the sleeve 24 comprises a cavity 36 in which a fin 37 of the rod 18 is disposed in the mounting position of the valve 7 in the sleeve 24 (FIG. figure 7 ), said fin and said cavity being arranged so that the rod 18 is integral in rotation with the sleeve 24 so that the connection rotation moves the tube 19 relative to the rod 18 between their locked and free positions.

Likewise, after filling, the return to the upright position of the refillable bottle - source 8 of product has the notches 35 at the bottom of the high reach 19b, that is to say in the unlocked closed position of the valve 13 , so that the disconnection rotation of the bottle induces a displacement of the tube 19 relative to the rod 18 to their locked position.

In particular, the connection rotation angle is equal to the unlocking rotation angle which corresponds to the angular offset between the low bearing 19a and high 19b. Therefore, depending on the gesture desired for the connection, for example more or less than a quarter turn, the angular offset of the low bearing 19a and high 19b must be adapted.

In the figures, the sleeve 24 comprises a central stud 38 disposed in the sleeve 28 by means of arms 39, the cavity 36 being formed in said stud, for example in the form of a cross-shaped orifice in which four fins 37 formed under the notches 35 are arranged. Alternatively, the recess 36 may be arranged to allow the engagement of the notches 35 to secure in rotation the rod 18 and the sleeve 24 during connection.

Advantageously, the filling valve 7 and / or the sleeve 24 are equipped with a cap 40 arranged to maintain the tightness of the tanks 2, 23 between two fillings. Each cap 40 comprises a connecting device which is complementary to that of the filling valve 7 or the sleeve 24. Thus, the caps 40 can be removed before filling and delivered after filling according to a gesture which is similar to that respectively of the disconnection and connection of the refillable bottle on the source 8 of product.

In relation to figures 4 , the cap of the bottle comprises a locking means of the valve 13 in the closed position to disable said locking by removing said cap prior to filling.

In particular, the locking means may comprise a magnet 41 integral with the cap 40, the rod 18 having magnetic properties for its magnetic immobilization when said cap is mounted. Thus, after removal of the cap 40, in the absence of magnetic force, the movement of the valve 13 between its closed and open positions becomes free in order to perform the filling, in particular by reversal.
