Definitions

  • the present invention relates to a particular fluid dispenser commonly referred to as " Duo Dispenser " because it comprises two often separate dispensing units each comprising a fluid reservoir defining an opening, a dispensing member for sampling and dispensing fluid from the reservoir and a fastener for fixing the dispensing member on the opening of the reservoir.
  • the dispensing member is a pump, but it can also sometimes be a valve.
  • the opening of the reservoir is often in the form of a neck which protrudes above a tank body for containing the fluid.
  • the fixing member it is often in the form of a ring inside which the dispensing member is fixed and fastening means for making a solid and often tight attachment to the opening or the neck of the tank.
  • This type of distributor duo finds a preferred application in the case where two basic products should be mixed at the last moment.
  • Such dispensers can be used in the field of pharmacy, cosmetics or even perfumery.
  • each dispensing unit comprises an actuating rod through which the fluid product is discharged at each actuation.
  • the duo distributor comprises two distribution units, because it can also include three or more, the two actuating rods are capped with a common dispensing head which can be pressed to simultaneously actuate the two rods actuating the two units.
  • an outer shell in which both units are installed.
  • the shell encloses at least the two tanks leaving at least the two actuating rods of the two units protruding outside the hull.
  • the shell comprises a bottom which serves as a bearing surface for the two dispensing units.
  • the units rest on the bottom of the hull.
  • a closure cap may be used which is disposed and attached to the upper end of the shell to hold the two dispensing units in place within the shell.
  • US 2002/0117516 discloses a dual dispenser comprising two aerosol cans and a housing.
  • the bombs each comprise a can, a valve and a crimping ring for fixing the valve on the opening of the can.
  • the housing defines two receiving tubes provided with internal clipping profiles.
  • the bombs are respectively held in their receiving tubes at their crimping rings engaged with the attachment profiles.
  • the casing caps the top of the aerosol cans leaving their lower parts visible.
  • the preamble of claim 1 is based on this document.
  • the object of the present invention is to overcome this aforementioned drawback of the prior art by defining a fluid dispenser of the duo type which offers great modularity as to the use of the distribution units that it incorporates. It may in particular use units whose reservoir has different capacities.
  • the present invention provides a fluid dispenser comprising two separate dispensing units each comprising a fluid reservoir defining an opening, a dispensing member for taking and dispensing fluid from the reservoir and a fastener for fixing the dispensing member on the opening of the tank, and a common outer shell in which at least the two tanks are housed, the shell comprising receiving means for receiving and holding the two distribution units inside the shell.
  • holding means for cooperating with the receiving means of the shell to separately maintain the respective unit within the shell.
  • the fastener forms the holding means.
  • each distribution unit is kept distinctly at its fastener, that is to say at the opening of the tank, in the receiving means formed by the shell.
  • each unit no longer need to rest at the bottom of the hull, so that the hull does not even need to form a bottom, which can then advantageously be reported.
  • the latching of the units in the receiving means can be done through the open bottom of the hull or from the top of the hull. It is then easily understood that it is possible to use tanks of different capacity or different shape, since the configuration of the tank, or at least its height is no longer related to the configuration of the shell dressing outside. This implies a great modularity in the use of the distribution units that are integrated into the distributor.
  • each distribution unit is completely separate, and form before assembly in the hull two completely equivalent and interchangeable units, there is no problem of arrangement of the units inside the hull.
  • the only links between the two units are constituted by the receiving means of the hull and the common distribution head which caps the two distribution units. However, it is possible to envisage application cases in which there is no common distribution head, but on the contrary two separate dispensing heads.
  • the receiving means form two detent housings, the holding means forming a peripheral profile intended to be snapped into a respective housing.
  • the fact of providing two separate detent housings shows the independence of the two distribution units, and thus the modularity of the dispenser.
  • the holding means comprise a radial flange which extends outwards.
  • the dispenser may further comprise locking means for blocking the dispensing units in the receiving means.
  • the locking means comprise a cup fixed on the shell and coming into blocking engagement with the dispensing units.
  • the dispenser comprises a dispensing head for simultaneously actuating the two units, the cup forming a sleeve inside or outside of which the dispensing head is slidably engaged, the sleeve comprising retaining means suitable for prevent the head from disengaging from the sleeve.
  • the dispensing head is adapted to be mounted on actuating rods of the respective units, the retaining means making it possible to preposition the head on the rods. actuation, the final mounting of the head on the rods occurring during the first actuation of the dispenser.
  • the shell is provided with a bottom, the tanks being out of bearing contact with the bottom.
  • the receiving means can be integrally formed by the shell.
  • the dispensing units can be engaged from above in the receiving means, so that the tanks first enter the shell through the receiving means.
  • the receiving means comprise two housings each comprising snap-in profiles and bearing surfaces, the holding means comprising a flange defining an upper face engaged with the snap-in profiles and a lower face engaged with the snap-fastening profiles. support surfaces.
  • the dispenser comprises a dispensing head movable by axial support so as to press the lower face of the flange on the bearing surfaces.
  • the dual distributor of the invention shown in the figures comprises two distribution units 1 and an outer shell 6 in which the at least some of the two distribution units are housed.
  • the two distribution units are associated with a common distribution head 5, but it could also have provided two separate heads connected by any means.
  • the dispenser comprises a bottom 8 attached to the lower end of the shell 6, a cup 7 associated with the upper end of the shell 6 and a cap 9 which caps the dispensing head 5 and which cooperates with the cup 7.
  • the bottom 8, the cup 7, and the cover 9 are optional, but advantageous.
  • the dispensing unit is generally designated by the reference numeral 1. It comprises a container 2 defining a drum 21, advantageously cylindrical, at the upper end of which is formed a neck 22 defining an opening 23 which communicates the interior. barrel 21 with the outside. On the other hand, the barrel 21 is provided at its lower end with a base member 25 which is advantageously mounted in the barrel 21.
  • the barrel 21 further comprises a scraper or follower piston 24 which is engaged to the inside of the barrel 21 so as to slide there sealingly.
  • the follower piston 24 is intended to move towards the opening 23 as the fluid contained in the reservoir 20 is extracted.
  • the fluid product stored inside the tank 20 is never in contact with the ambient air inside the tank 20.
  • the neck 22 is formed with an external reinforcement 220 which defines the upper end of the neck.
  • the container may be replaced by a bag system comprising for example a flexible bag associated with a rigid bag holder engaged with the fastener.
  • a bag system comprising for example a flexible bag associated with a rigid bag holder engaged with the fastener.
  • Other containers are also conceivable.
  • This container 2 is associated with a dispensing member 3 and a fastener 4 as shown in Figure 3 in an enlarged manner.
  • the organ of 3, which is here preferably a pump, comprises a body 31 defining at its lower end an inlet duct 32 communicating with the interior of the tank 20. At its upper end, the body 31 forms a snap-fitting flange 33 which protrudes radially outwards.
  • the dispensing member comprises an actuating rod 34 which is axially displaceable inside the body 31. This actuating rod 34 defines an internal discharge duct through which the product sampled and pumped by the pump 3 is dispensed.
  • the fixing member 4 comprises snap receiving means 41 for receiving the ratchet flange 33 of the body 31 of the pump 3.
  • These receiving means 41 comprise an inner peripheral flange 411 on which the flange 33 comes in support.
  • These receiving means 41 are located at the upper end of the fastener.
  • the fixing member forms a turret 4 which is in the form of a substantially cylindrical section disposed concentrically around the body 31 leaving an intermediate annular space.
  • the turret 40 forms a shoulder 421 which extends radially outwardly.
  • This shoulder 421 serves as a bearing surface for an O-ring seal 221 which is advantageously pre-engaged and maintained by friction around the body 31 of the pump 3 as can be seen very clearly in FIG.
  • the fastener forms snap fastening means 42 defining a snap-fitting housing partially closed by a peripheral bead 422 which extends inwardly.
  • These fixing means 42 are intended to receive the outer peripheral reinforcement 220 formed by the neck 22.
  • the housing formed by the fixing means 42 is designed such that the upper end of the neck 22 is fixedly received inside the housing by compressing the seal 221 against the shoulder 421.
  • the fastener forms a second shoulder outward 44 whose function will be given below.
  • this shoulder 44 the fastener forms a peripheral radial flange 43 which extends outwards. Its function will also be given below.
  • the dual distributor of the present invention integrates two distribution units. of that type. It is preferable, if not essential, that the units comprise an entire flange 43 identical. Likewise, it is preferable that the distance separating the flange 43 from the upper end of the actuating rod 34 be identical for all the units.
  • the fastener and the dispensing member may vary from one unit to another.
  • the containers 2 may vary in shape, that is to say in height or width.
  • FIGS. 4 and 5 illustrate an embodiment of an outer covering shell used in the dispenser of FIG. 1.
  • the shell 6 is roughly in the form of a cylindrical section of ovoid shape or ellipsoidal as can be seen in Figure 5.
  • the shell 6 thus comprises a substantially cylindrical barrel 61 which terminates at its lower end by a detent pin 63 intended to cooperate with an attached bottom 8 visible in Figure 1.
  • a its upper end, the shaft 61 defines receiving means 62 which are here in the form of two housings 620 bordered by snap profiles 621 and bearing surfaces 622. These snap profiles 621 and these surfaces Support 622 may extend over the entire periphery of the housings 620, or as shown in Figures 4 and 5, only locally in the form of sectors.
  • Each housing 620 forms a passage opening which communicates the interior of the barrel 61 with the outside. It may be noted that the shell 6 is advantageously symmetrical in a plane passing between the two housings 620, as can be seen in FIG. 5. The shell surrounds the containers 2, at least partially, the collar 22 being able to project out of the shell. The shell could extend only over part of the height of the drum 61 or be made with windows.
  • the receiving means 62 are intended to cooperate with the flanges 43 which form holding means. More specifically, the outer peripheral edges of the flanges 43 are intended to cooperate with the snap profiles 621 formed around the housings 620.
  • each distribution unit 1 can be attached from above and held in the shell 6 at a housing 620 by first passing the tank 2 through the housing 620 until the flange 43 can be snapped into force under the snap profiles 621 on the stop surfaces.
  • the upper face of the flange engages with the snap profiles and the underside with the stop surfaces.
  • the receiving means may also comprise screwing means in place of the latching sectors. Each distribution unit is thus reported and fixed in place in a completely separate and independent manner.
  • the dispensing units 1 are thus connected to the shell 6 only at the level of the housings 620.
  • the attached bottom 8 may comprise centering means 82, which may be in the form of vertical bars intended to engage with the lower end of the barrels 21 to center the containers 2 inside the shell 6.
  • centering means 82 do not participate in the fixing of the distribution units 1 in the shell 6.
  • a cup 7 is fixed on the shell 6.
  • This cup is permanently block the two distribution units in the receiving means 62 of the shell.
  • This cup 7 comprises an outer skirt 71 snapped around the upper end of the shell 6, where it forms the receiving means 62.
  • the cup 7 forms a blocking wall 72 pierced with two openings whose peripheral edges engage with the respective dispensing units, advantageously at the shoulders 44 formed by the fixing member 4.
  • the cup reinforces the fixing of the units of distribution on the shell 6.
  • the cup 7 forms a sleeve 73 which extends freely upwards.
  • the outer wall of this sleeve 73 advantageously comes into frictional contact with the inner wall of a cover 9 intended to cap the dispensing units and which abuts on the outer skirt 71. This is a classic characteristic for a protective cover.
  • the inner wall of the sleeve 73 forms retaining means 731 whose function will be given below.
  • the two distribution units 1 are associated with a dispensing head 5 which is advantageously common to both units.
  • This dispensing head 5 comprises an upper bearing surface 51 on which one can press with the aid of one or more fingers to operate simultaneously the two units.
  • the head forms two connecting sleeves 52 for receiving the upper ends of the respective actuating rods 34 of the two units.
  • These two connecting sleeves 52 are extended by outlet ducts (not shown) which open at two separate dispensing or distribution ports (not shown).
  • the dispensing head 5 comprises a peripheral skirt 53 which extends freely downwards.
  • This skirt 53 defines, for example at its free lower end, a peripheral retaining profile 530 intended to cooperate with the retaining means 731 formed for example at the upper end of the sleeve 73.
  • the dispensing head 5 is held temporarily in place relative to the cup 7, and therefore, with respect to the dispensing units 1. It can be seen in Figure 1 that the actuating rods 34 of the two units are not engaged to the The distribution head 5 is thus only pre-positioned on the actuating rods 34 and held in this position by the cooperation between the skirt 53 and the sleeve 73. The final position of the head 5 distribution will be reached after the first actuation of the distributor by pressing on the bearing surface 51.
  • the thrust on the surface 51 will cause commitment to f actuating rods 34 inside the sleeves of connection 52.
  • the temporary retention of the skirt in the sleeve 73 will be broken.
  • the protective cover 9 engaged on the cup 7 also has the function of protecting the dispensing head 5 in its pre-engaged position on the distribution units.
  • the thrust on the actuating head has the effect of pressing the lower face of the flange 43 on the bearing surfaces 622 formed by the shell. Since the bearing surfaces and the underside of the flange extend in a plane of contact perpendicular to the axis of the thrust exerted on the head, it is impossible to extract the units from their respective housings when of distribution.
  • each distribution unit is a separate entity that can be easily attached to the hull independently and separately.
