Definitions
- the present invention relates to a pressurized fluid product dispenser comprising an external canister, an internal flexible bag and a valve mounted on an opening of the bag.
- An intermediate space is thus created between the can and the bag and this intermediate space is intended to be at least partially filled with a gas under pressure so as to exert pressure on the flexible bag.
- a movable member of the valve By actuating a movable member of the valve, the fluid product stored under pressure inside the bag can be dispensed through an outlet formed by the valve.
- This is a conventional dispenser in many fields of application, such as cosmetics, pharmaceuticals, body care products, food, etc.
- valve outlet may be formed by the free end of a hollow valve stem, internally defining an outlet conduit, or alternatively, this valve outlet may be formed by an orifice for receiving a connecting sleeve, formed by a dispensing head which is pressed to actuate the valve.
- gas and fluid are injected through the valve outlet. It is therefore essential that the gas finds a passage from the valve outlet to the intermediate space without penetrating inside the pocket.
- the fluid product injected through the valve outlet must find a passage from the valve outlet to the pocket without penetrating the intermediate space. It is therefore necessary to create two separate passages, namely a passage for the gas to the intermediate space and a passage for the fluid to the flexible bag.
- these two separate passages may for example be generated by a valve located inside the valve.
- This valve is adapted to open from a certain predetermined pressure threshold.
- the gas can be injected into the intermediate space with a pressure lower than the predetermined threshold, while the fluid product can be injected into the pocket with a pressure greater than the predetermined threshold.
- This is a first filling technique.
- this technique requires precisely determining the injection pressures of the gas and the fluid product so as not to mix the gas and the fluid in the intermediate space and / or in the pocket.
- Another conventional technique is to use the movable member of the valve to temporarily seal the passageway communicating the valve outlet and the bag.
- the passage connecting the outlet of the valve to the bag is open, so as to suck the contents of the bag through the open valve from its output.
- the evacuation or emptying of the bag is usually performed by the manufacturer of the valve and the bag before shipment to the filler gas and fluid.
- the dispenser bag is thus delivered in its folded or wound state, so that the gas and fluid filler can easily introduce the bag into the can, and fix the valve on the edge of the can, for example using a fixing cup.
- the bag remains folded or rolled up, and it is only when filling the bag with the fluid that the bag will unfold and occupy a substantial part of the internal volume of the can, the other part of the can being occupied by the gas under pressure. Therefore, with this particular type of pressure distributor, it is necessary at first that the passage connecting the outlet of the valve to the pocket is open to allow evacuation of the pocket, it is necessary in a second time to close the connecting passage the outlet of the valve to the pocket to allow the filling of the intermediate space with a gas under pressure, and it is finally necessary that the passage connecting the outlet of the valve to the bag is again open to allow the filling of the bag with a fluid to be dispensed. It has been seen above that the filling techniques in gas and fluid product of the prior art are not fully satisfactory.
- the present invention aims to overcome the aforementioned drawbacks of the prior art by defining a fluid dispenser under pressure in which the gas filling and fluid filling operations, as well as possibly the evacuation operation of the pocket, are particularly simple and without risk of mixtures of gas and fluid product.
- Another object of the present invention is to allow these easy filling operations while not substantially complicating the structure of the valve. This valve must be able to be produced at a relatively small cost.
- the present invention provides a fluid dispenser under pressure comprising a substantially rigid outer container, an internal flexible pouch for containing a fluid, the bag being disposed in the container so as to define an intermediate space between the can and the bag, this intermediate space being intended to be at least partially filled with a pressurized gas so as to exert pressure on the flexible bag, a valve mounted on an opening of the bag, the valve comprising an actuatable movable element of so as to allow the pressurized fluid product to be dispensed through an outlet of the valve, the dispenser further comprising closure means adapted to close the passage between the bag and the valve outlet, regardless of the pressure at the of the valve outlet and / or actuation of the movable member.
- the sealing means seal the passage between the bag and the valve, without it being necessary to act on the movable member of the valve or to adjust the injection pressure of the gas and / or fluid product.
- the sealing means seal the passage between the bag and the valve, even when the valve is at rest, and subjected to no particular pressure, other than the atmospheric pressure.
- the movable element engages with the closure means, at the end of travel of the movable element, to break or undo the closure generated by the closure means and thus release the passage between the pocket and the valve outlet.
- the movable member is used to break or undo the closure of this passage.
- the closure means comprise two parts initially connected in a sealed manner, these parts being able to be separated from one another, thus making it possible to establish a passage between the pocket and the exit of valve.
- the movable member engages one of the parts to separate it from the other end-of-travel part of the movable member.
- the valve comprises a return spring which returns the valve in the closed position, the spring bearing on the sealing means.
- the spring is supported on a part of the closure means which rests on a stop formed by a pocket support on which the opening of the pocket is fixed.
- the valve comprises a fixed valve body and a movable valve stem, the valve outlet being formed by a free end of the valve stem, the means shutter being movable relative to the body between a non-sealed initial position and a sealed end position.
- the sealing means are biased in sealing engagement against the body.
- the opening of the bag is fixed on a pocket support engaged with the valve body, the support being movable relative to the body so as to urge the sealing means sealingly against the body.
- the initial unsealed position it is possible to evacuate or empty the contents of the pocket to be able to fold or wind it.
- the closure means Once the closure means have been moved to their final sealed position, it is possible to fill the gap with pressurized gas. Once this gas filling step is performed, it is then necessary to undo or break the closure generated by the closure means to allow the injection of the fluid into the flexible bag.
- the sealing means comprise a ring intended to bear tightly against the body and a plug disposed in the ring, the cap and the ring being sealingly connected before their separation.
- the cap and the ring are made integrally by being connected together by a bridge of material capable of breaking to allow their separation.
- the cap rests tightly on the crown before their separation.
- the ring and the plug, while sealed together, can be moved in one piece from the unsealed initial position to the sealed end position. Then, it is possible to separate the plug of the ring, either by breaking the material bridge, or by disengaging the cap of the ring, which can advantageously be achieved by means of the movable element when it arrives at the end of race.
- the invention also relates to a method of filling a fluid dispenser as defined above, the method comprising the steps of: filling the intermediate space with gas under pressure, while the closure means prevent any passage between the valve outlet and the bag, to actuate the valve so as to break the closure means to create a passage between the bag and the valve outlet, then fill the bag through the valve.
- the method comprises the initial step of evacuating the contents of the valve, while the sealing means are in initial unsealed position.
- the method comprises exerting a thrust on the pocket support between the gas evacuation and filling steps to bring the closure means to the sealed end position.
- An interesting feature of the invention that can be independently protected is that the displacement of the pocket support relative to the body of the valve is used to seal the passage connecting the outlet of the valve to the valve. poached. This shutter operation is advantageously performed after the evacuation operation of the pocket. The passage being thus closed, the filling of gas is possible. Then, it is the deep depression of the movable member of the valve that allows to break, break, or undo the closing of the passage between the valve outlet and the pocket.
- FIGS. 1a, 1b, 1c, 1d, 1c and 1c represent various stages of assembly and filling of a pressure fluid dispenser according to a first embodiment of the invention
- Figures 2a and 2b correspond to Figures 1a and 1f for a second embodiment of the invention
- Figures 1a and 1f for a second embodiment of the invention
- Figure 3 is a view corresponding to Figure Id for a third embodiment of the invention. Reference will firstly be made to FIGS. 1a-1e to explain in detail the structure and operation of the pressure fluid dispenser according to the first embodiment of the invention.
- the other embodiments of Figures 2a, 2b and 3 have a structure and operation substantially identical to those of the first embodiment, with the exception of the closure means.
- FIG. 1a will serve as a basis for describing in detail the structure of the distributor, and more particularly of the valve, which is generally designated by the digital cooling 3.
- the device also comprises a substantially rigid outer container 1 which can for example be made of metal or plastic.
- the dispenser also includes a flexible pouch 2 which can be made of any flexible material, such as plastic, metal or a laminated complex of plastic and metal.
- the dispenser also comprises a fixing cup 4 which serves to hold the valve 3 on the can 1.
- the valve 3 comprises a valve body 31 having a substantially cylindrical or tubular general configuration. At its upper part, the body 31 forms a flange 301 intended to engage inside a housing 43 formed by the fixing cup 4.
- This housing 43 is partially closed on the top by a flange 42 which defines a central opening.
- the attachment cup 4 forms a fixing ring 41 intended to be crimped on the can 1. More particularly, as can be seen in Figure 1a, the can forms an edge 11 defining an opening which gives access inside the can. According to a conventional embodiment, the edge is The fixing ring 41 is advantageously crimped on this hemmed edge 11.
- the crown may be provided with a flat seal which extends over the entire periphery of the crown, which It is a characteristic quite conventional for fixing a valve cup for an external can.
- the valve body 31 also forms an interior shoulder 312 which is oriented downward and which is located on an inner periphery of the body. Below this shoulder 312, the body 31 forms a skirt 313 which is advantageously provided at its inner wall with several attachment profiles.
- the valve 3 also includes a valve seal 33 which is disposed within the body 31 just below the flange 42 formed by the cup 4.
- the valve seal 33 is a flat seal defining a central opening which is disposed of concentrically with that of the flange 42.
- the valve 3 also includes a valve stem 32 which extends substantially axially through the passage openings formed by the valve seal 33 and the flange 42.
- the valve stem 32 extends upwardly and comprises a free upper end which defines an outlet 321 of the valve. It is through this outlet 321 that the first pressurized fluid inside the distributor leaves the valve 3.
- valve 3 defines a movable cap 34 which is urged against the valve seal 33 by a return spring 35.
- the movable cap 34 defines a lip 343 which is pushed into sealing contact under the seal
- the spring 35 also pushes the movable cap 34 into pressed contact against the valve stem 32. It may be envisaged to make the valve stem 32 and the movable cap 34 integrally: however, in practice these two pieces are often made separately.
- the valve 3 is also provided with a pocket support 36 on which an opening 21 of the bag 2 is sealed, for example by welding.
- This pocket support 36 comprises a sleeve 361 engaged within the skirt 313 of the valve body 31.
- the sleeve 361 of the pocket support 36 is also provided with hooking profiles intended to engage the profiles of the body. corresponding hooking, formed inside the skirt 313 of the valve body 31. According to the invention, the sleeve 361 can be received inside the skirt 313 at different heights, so that it is possible axially displacing the pocket support 36 relative to the body 31.
- the pocket support 36 also forms a bearing flange 362 which extends radially outwardly from the lower end of the sleeve 361. Below the flange 362, the pocket support 36 forms a fastener 364 on which the opening 21 of the pocket 2 is fixed, for example by welding.
- the pocket support defines an axial central passage duct which passes through the plastic sleeve 61 and the attachment ferrule 364.
- one or more stops 363 are formed inside the support. .
- these stops may be made by ribs that extend radially inwardly. These ribs, however, do not obstruct the axial passage formed by the pocket support 36.
- the valve 3 is further provided with closure means 5 which are able to close the passage which makes the bag support 36 communicate with the dispensing outlet 21 of the valve.
- These sealing means 5 are here partially disposed inside the sleeve 361 of the bag support 36 resting on the upper end of this sleeve.
- these sealing means 5 comprise a sealing ring 51 in non-sealing engagement on the upper end of the sleeve 361 and a plug 52 which extends inside the the ring 51 and inside the sleeve 361, without come into tight contact with it.
- the sealing ring 51 is disposed below the shoulder 312 of the body 31 without being in contact therewith.
- the ring 51 is not in sealing contact with the skirt 313 of the body 31. Consequently, in the position of FIG. 1a, there is a passage which bypasses the sealing means 5, which do not play. therefore by their role of filling. Indeed, by pressing lightly on the valve stem 32, it is possible to communicate the dispensing outlet 321 with the inside of the pocket holder 36, and thus with the inside of the pocket 2. D ' On the other hand, we can also notice that the return spring
- the sealing means 5 are here advantageously made in one piece, the ring 51 being in fact integrally connected to the cap 52 by a bridge of brittle material 53 which extends over the entire outer periphery of the button 52.
- Figure Ib shows a subsequent assembly step of fixing the opening 21 of the bag 2 on the attachment end 364 of the pocket holder 36.
- the fixation is most often by welding.
- FIG Ic illustrates a subsequent step of assembling the dispenser, of moving the pocket support 36 relative to the body 31.
- the flanges 362 are used to exert a thrust in the direction of the arrows annotated "PUSH". This has the effect of raising the sleeve 361 inside the skirt 313.
- the dispenser or more precisely the valve 3 equipped with its cup 4 and provided with its pocket 2, is thus sent to people who will fill the gas or fluid.
- the bag 2 which has been removed from its contents, is maintained anyway in this empty state because the closure means 5 seal the passage between the bag and the valve outlet 321. It is not It may not be necessary to keep the pouch folded or rolled up using a tear tape. Indeed, the pocket remains in this configuration, since it is isolated from the outside by the closure means 5. This is a characteristic that can be protected in itself. More specifically, the sealing means 5 can be used in a valve for the sole purpose of initially allowing the evacuation of the bag 2 and then the isolation of the bag 2 relative to the outside.
- closure means 5 are movable between a non-sealed initial position and a sealed end position is itself a protectable feature.
- the displacement of the sealing means is here carried out using the pocket support which is mounted axially displaceable with respect to the valve body.
- the valve thus fully equipped as shown in Figure Id, can be mounted in a can 1, engaging the crown of the fixing cup 4 on the edge 11 of the can. This is possible because the bag 2 is kept in its folded or rolled compact state. It is then sufficient to crimp the crown 41 on the edge 11 to make a tight connection of the cup 4 on the can.
- the effective internal volume of the can 1 is thus partially occupied by the folded or wound pocket 2, the valve 3 and an intermediate space E located between the can and the pocket 2.
- This intermediate space E will serve as a receiving space for the gas thruster under pressure. Indeed, in this particular type of fluid dispenser under pressure, the propellant gas is not mixed with the product to be dispensed, but stored in an intermediate space that surrounds the bag.
- the pressurized gas stored in this intermediate space E thus exerts pressure on the bag 2 and its contents are then pressurized.
- the step of filling this intermediate space E with a pressurized gas G can be performed while the dispenser is in the configuration shown in Figure 1c.
- the closure means 5 seal the passage communicating the interior of the bag 2 with the dispensing outlet.
- the fluid filling step can then be carried out as shown in FIG.
- the sealing means 5 are first broken by separating the ring 51 from the plug 52. This is done by means of the movable member 34 which is provided with a support bushing 345 intended to to engage with the plug 52.
- the movable member 34 By pressing the valve stem 32 down fully, the movable member 34 will push on the plug 52, which will cause the rupture of the bridge of brittle material which connects the ring 51 and the plug 52
- the separation of the closure means into two distinct parts separated and spaced apart from each other makes it possible to ensure a passage between the inside of the bag 2 and the valve stem 32. Indeed, the passage 54 formed between the plug 52 and the sleeve 361 allows the passage of the fluid as soon as the valve is open.
- the plug 52 once separated from the ring 51, comes to rest on the stops 363 formed by the pocket support. The plug 52 is held in a perfectly stable manner on these stops 353, since it is urged by the return spring 35. Once the closure means have been separated, a bell 6 can be brought back onto the valve stem. 32 and inject fluid product F into the valve which is held slightly open. The fluid product can flow inside the bag since the sealing means no longer seal.
- the gas and fluid filling operations can be performed safely without the risk of mixing the gas and the fluid product.
- a slight actuation of the valve stem 32 is not sufficient to break the closure means. For this, it is necessary to push down and exert enough pressure to separate the cap 52 of the ring 51.
- the means of shutter does not yet provide sealing.
- FIGS 2a and 2b illustrate an alternative embodiment.
- Figures 2a and 2b correspond to Figures 1a and 1f of the embodiment, illustrating gas filling and fluid filling operations respectively.
- the sealing means 5 ' here consist of two separate parts, namely a ring 51' and a plug 52 '.
- the ring and the plug are made separately and the plug 52 'is attached to the inside of the ring 51'.
- the plug 52 ' forms a peripheral annular bead 521 which extends radially outwardly.
- This cord 521 provides sealingly on an inner peripheral edge 511 formed by the ring 51 '.
- the cap 52 ' is in sealing contact with the ring 51', so that the closure means 5 'cut the passage connecting the inside of the bag 2 to the valve outlet, just as the sealing means 5 of the first embodiment.
- the gas can then be injected through the valve stem to fill the intermediate space E defined between the can and the pocket.
- FIG. 3 illustrates a third embodiment in which the closure means 5 "also comprise a ring 51 and a plug 52, which are here permanently connected integrally.
- the plug 52 forms a pierceable membrane 55 which can be pierced when the movable cap 34 is fully depressed.
- the movable cap 34 forms a piercing needle 346 capable of piercing or cutting the membrane 55 formed by the sealing means 5 ".
- the valve is devoid of valve stem and the valve outlet 321 is directly formed at the seal 33 and cup flange. This valve is more particularly adapted to be associated with a dispensing head which comprises a sleeve which will bear against the movable cap 34.
- closure means fulfill their shutter function independently of the pressure of the injected fluid gas and independently of the actuation of the valve.
- the maximum actuation of the valve is necessary to break the sealing means.
- valve stem and / or the movable cap 34 together or individually constitute a movable member of the valve on which one can act to actuate the valve. It is of course possible to remove the stem first and second embodiment of the valve and equipping the valve of the third embodiment of a valve stem.
- the sealing means of the invention thus successively provide a passage for carrying out the evacuation of the bag, a sealed seal for injecting the gas under pressure, again a passage for injecting the fluid product.
