Definitions

  • the present invention relates to a fluid dispenser comprising a reservoir and a dispensing head through which the fluid product of the reservoir is dispensed.
  • the reservoir comprises an opening and the dispensing head comprises a fixing ring that engages in the opening.
  • the ring and the opening form sealed final mounting means which fix, in final mounting position, the dispensing head stably and tightly in the opening of the tank.
  • Such fluid dispensers are frequently used in the fields of cosmetics, perfumery or pharmacy.
  • reservoirs whose opening is particularly large, which may have a diameter greater than 3 or 4 cm.
  • the reservoir may for example be in the form of a cylindrical cup inside which is slidably mounted a follower piston which is intended to move in the bucket as fluid is extracted from the reservoir.
  • the opening of the reservoir then extends in the extension of the bucket and has the same diameter as the reservoir.
  • a distribution head of large diameter, but of reduced height is frequently used. This means that the dispensing head penetrates only weakly inside the opening of the tank.
  • a known type of dispensing head has a substantially flat bottom face, against which the follower piston comes into contact when the reservoir is empty.
  • such a dispenser comprises a reservoir whose opening is large and a dispensing head which penetrates weakly inside the tank.
  • the dispensing head When mounting such a dispenser, it first begins by filling the tank with fluid. Then, the dispensing head is deposited in the opening of the tank without performing the final assembly. There is still no seal between the dispensing head and the reservoir. An optional next step, but more and more common, is to subject the dispenser to a vacuum to evacuate the air in the tank. The final final step is to permanently mount and seal the dispensing head on the tank.
  • the distributors are routed through different stations by means of a conveying path. More specifically, the tank is deposited on the conveying path which allows to convey it from one station to another where different stages of assembly are performed.
  • the dispensing head is simply deposited in the tank opening after the filling step, it sometimes happens that the dispensing head falls from the reservoir when it is routed to the next vacuum conditioning stage. or final assembly.
  • the drop of the dispensing head can be caused by the sudden start of the conveying path which takes the reservoir filled with fluid product.
  • the dispensing head falls all the more easily as it penetrates very weakly inside the tank, and the tank opening is important. It only takes one dispensing head that falls from its tank to block the entire assembly line.
  • the document DE 197 41 957 discloses a fluid dispenser according to the preamble of claim 1 and its filling process wherein the head is temporarily mounted and sealed on the reservoir.
  • the document EP 0 823 288 discloses a dispenser provided with an initial vent device facilitating on the one hand the insertion of the dispensing head on the tank during its mounting force, and secondly the priming of the pump.
  • the document FR 2 900 643 provides for discharging the air from the reservoir through grooves formed by a fixing sleeve which supports a pump. This document does not describe a pre-arranged provisional position.
  • An object of the present invention is to prevent the drop of the dispensing head while retaining the possibility of subjecting the dispenser to vacuum packaging.
  • the present invention is particularly applicable to the field of cosmetics with the type of dispenser above, but it can also apply to other areas with different types of tank and dispensing head.
  • the present invention proposes that the ring and the opening also form temporary snap-fastening means for fixing, temporarily in the pre-assembled position, the dispensing head temporarily and unsealed in the opening of the reservoir.
  • the final mounting means are latching means.
  • the dispensing head is secured to the tank in premounted provisional position, which avoids any risk of loss or of falling of the dispensing head.
  • the provisional pre-assembly is not waterproof, it is possible to subject the dispenser, and more particularly the contents of the tank, to a vacuum to evacuate the air contained therein. Then, the dispensing head is mounted permanently and sealed on the tank.
  • the dispensing head is first preassembled in a non-sealed manner on the reservoir, then in a second step, the head is permanently snapped tightly on the reservoir. Between the two snaps, the dispensing head is integral with the reservoir, but it is still possible to perform vacuum packaging.
  • the mounting means comprise a first detent groove formed at the opening and a first detent rib formed by the fixing ring, the first rib being engaged snapped into the first groove. in final assembly position.
  • the pre-assembly means comprise a second detent groove formed at the opening and the first detent rib formed by the fixing ring, the first rib being in engagement snapped into the second groove in the premounted position.
  • the opening defines an upper annular edge, the second groove being located closer to the annular edge than the first groove.
  • the ring forms a second rib which snaps tightly into the second groove in the final mounting position.
  • the dispensing head is doubly snapped into the opening of the tank, thus increasing the stability of the head on the tank, but also the seal between the ring and the opening.
  • the opening defines an upper annular edge, the fixing ring forming a peripheral flange which bears on the edge of the opening in the final mounting position.
  • the reservoir comprises a follower piston which slides in a sealed manner inside a barrel closed by the reservoir, this follower piston moving between the pre-assembled position and the final mounting position to avoid any rise in pressure in the tank.
  • the dispensing head has a lower face oriented towards the reservoir, this lower face forming a closing roof for the reservoir, this lower face being substantially flat and projecting very little into the reservoir below the reservoir. fixing ring.
  • the present invention finds a particular advantage when the dispensing head has a flat bottom face which penetrates only slightly inside the tank. As mentioned above, this is the case of cosmetic pumps which are mounted on tanks having a large section opening.
  • the reservoir comprises a sliding shaft and a follower piston which slides in the barrel, the opening extending in the extension of the barrel. This means that the opening of the reservoir has a diameter substantially equal to that of the reservoir where the follower piston slides.
  • the fluid dispenser shown on the Figures 1 to 4 is a cosmetic product dispenser with a pasty or creamy consistency. This dispenser can nevertheless be used to dispense pharmaceutical products, such as ointments.
  • the dispenser comprises two main subsets, namely, a fluid reservoir 1 and a dispensing head 2.
  • the fluid reservoir 1 comprises a substantially cylindrical bucket comprising a cylindrical sliding shaft 15 closed at its lower end by a bottom 16.
  • the opposite end of the shaft 15 defines an opening 11 whose section is substantially or perfectly identical to that of the 15. Consequently, the tank 1 defines an opening 11 of large section, since it extends exactly in the extension of the barrel 15.
  • the tank 1 also comprises a follower piston 17 which is slidably mounted in a sealed manner. 15.
  • the follower piston 17 is initially disposed near the bottom 16, but it can be seen on the figure 1 that the follower piston 17 is not in contact with the bottom 16, but is instead separated from this bottom by a short distance.
  • the bucket and the follower piston can be made by injection molding material plastic. One can also consider making the bucket glass or metal.
  • the opening 11 comprises an outer wall and an inner wall connected at the upper end of the tank 1 by an annular edge 14.
  • the inner wall of the opening 11 defines from bottom to top a first groove of 12, a second ratching groove 13 and a frustoconical inlet chamfer 141 which joins the upper edge 14.
  • the two ratchet grooves 12 and 13 are separated by a first bead 123.
  • the second ratchet groove 13 is separated from the frustoconical chamfer 141 by a second bead 134. It can be seen from the figures that the internal diameter of the first ratchet groove 12 is smaller than the internal diameter of the second ratchet groove 13.
  • the dispensing head 2 comprises a pump 3 defining an inlet 31 communicating with the reservoir 1.
  • the pump 3 defines a pump chamber 32 of variable volume for putting the fluid under pressure.
  • the pump also includes an attachment ring 33 which engages with the opening 11 of the reservoir.
  • the dispensing head also comprises a pusher 4 associated with the pump 3 for actuating it.
  • the dispensing head comprises a protective cover 5 removably mounted on the fixing ring 33 and masking the pusher 4. This is a quite conventional design for a dispensing head in the field of cosmetics, pharmacy or perfumery.
  • the fixing ring 33 comprises a first detent rib 34 and a second detent rib 35 separated by a groove 345.
  • the maximum outside diameter of the first detent rib 34 is smaller than the maximum outside diameter
  • the fixing ring 33 also forms a peripheral flange 36 projecting radially outwards and which is intended to bear against the annular edge 14 of the opening 11.
  • the fixing ring 33 is seen in the provisional pre-assembly position in the opening 11 of the tank 1.
  • the peripheral flange 36 does not bear against the annular edge 14.
  • the second ratchet rib 35 is in contact with the input chamfer 141, while the first ratchet rib 34 is housed in the second ratching groove 13.
  • the first ratching groove 12 is empty.
  • no sealing is performed between the ring 33 and the opening 11. Therefore, the contents of the tank 1 still communicate with the outside. It is possible to subject the dispenser in this pre-assembled temporary position to a vacuum in order to evacuate the air present inside the tank.
  • the dispensing head is perfectly stable on the tank 1 in the pre-assembled provisional position. It is sufficient that the head is integral with the tank, even if it still has a certain degree of freedom.
  • the first sealing rib 34 is loosely received inside the second latching groove 13, and the bearing of the second detent rib 35 on the entry chamfer 141 is not squeezing.
  • the first ratchet rib 34 is trapped in the second ratchet groove 13.
  • the maximum external diameter of the first ratchet rib 34 to be smaller than the maximum internal diameter of the second ridge. snap 13.
  • the dispenser in this premounted provisional position can thus be conveyed on the conveyor path to the sealed final assembly station, and optionally to a vacuum evacuation station.
  • the fixing ring 33 is seen in the final sealed mounting position inside the opening 11 of the tank.
  • the peripheral flange 36 is now resting on the edge
  • the first ratchet groove 34 is housed inside the first ratchet 12, while the second ratchet 35 is housed inside the second ridge 12.
  • the locking ring 33 is then in sealing contact with the opening 11 over the entire periphery so as to isolate the inside of the tank from the outside.
  • the sealing can be performed at any point of contact between the ring 33 and the opening 11.
  • a seal can for example be made at the rib 34 in contact with the groove 12.
  • Another seal can be achieved at the level of the rib 35 in contact with the groove 13.
  • Another sealing contact can be made between the flange 36 and the edge 14.
  • two seals are made, respectively at the two ribs 34 and 35 in contact with each other. grooves 12 and 13.
  • it ensures a perfect seal of the dispenser, and increased stability.
  • two separate snaps on the height of the opening 11 provide perfect stability, and advantageously an inguermontact distributor.
  • the dispensing head has a bottom face 3i which is substantially flat and which penetrates very weakly inside the tank.
  • this is a particular configuration of dispensing head which is often used in the field of cosmetics. With this type of configuration, the head penetrates very little inside the tank and would normally tend to fall from the tank on the assembly line between the moment when the head is simply deposited on the tank and the moment when the head is mounted permanently on the tank. With the present invention, it eliminates any risk of falling from the dispensing head premounted temporary position, while maintaining the possibility of vacuum packaging.
