Definitions

  • the present invention relates to a fluid dispenser device intended to be associated with a fluid reservoir to thereby constitute a fluid dispenser.
  • a fluid dispenser device By actuation of the dispensing device, the fluid product, dosed or not, is removed from the fluid reservoir and conveyed to a fluid outlet, for example in spray form or in the form of cord or hazelnut.
  • a fluid outlet for example in spray form or in the form of cord or hazelnut.
  • Such a dispensing device can in particular be used in the fields of perfumery, cosmetics or even pharmacy.
  • the fluid dispensing devices comprise an outlet valve formed of a valve seat and a movable member sealingly urged against the valve seat.
  • the outlet valve is formed at the outlet of the chamber in which the fluid product is pressurized.
  • the valve opens when the pressure in the chamber reaches a predetermined value.
  • the opening of the valve is materialized by the detachment of the movable member from its seat, thus defining a passage for the fluid under pressure. This is a quite conventional feature for a pump or valve valve.
  • the outlet valve to ensure a perfect seal, particularly at rest, must be constrained so that the movable member exerts pressure on the seat.
  • a return or pre-compression spring is used to permanently bias the movable member against its valve seat. It must be understood that the stiffness of the spring does not weaken, so as to ensure in time a satisfactory elastic bias of the movable member against its seat. A loss of stiffness of the spring could lead to a leakage failure of the outlet valve, and the device of distribution will no longer be able to fulfill its role. In this case, the dispensing device could leak at rest.
  • dispensing devices that are switchable between a locked position, in which one can not actuate the device, and a position of use, in which one can operate the device. In both positions, the outlet flap is closed. The position of use corresponds to the rest position of the device, from which the dispensing device can be actuated so as to open the outlet valve.
  • relative displacements such as rotations or translational displacements.
  • An object of the present invention is to relieve the action of the spring when the dispensing device is not used. Another object is to maintain the bias of the movable member against its seat other than by the spring. Still another object is to use the locking mechanism of the prior art to supplant the action of the spring on the movable member.
  • the present invention provides a fluid dispensing device having an outlet valve comprising a seat and a movable member sealingly urged against the seat, the dispensing device being switchable between a locked position and a desired position. in which the outlet valve is closed, the dispensing device not being operable in the locked position, while it is operable in the position of use, the movable member being biased by resilient means against the seat in position of use, characterized in that the movable member is biased by support means, other than the elastic means, against the seat in the locked position.
  • the locking mechanism therefore serves not only to prevent the actuation of the distribution device, but also allows to press the movable member against its seat, instead of the elastic means.
  • the support means are substantially rigid, so that they are not elastic.
  • the elastic means are expanded in the locked position, so that they undergo no stress or deformation.
  • the elastic means are formed of plastics material. Indeed, there has already been in the prior art many attempts to replace the metal springs by plastic springs. However, these plastic springs, because they are permanently forced to apply the movable member against the seat of the outlet valve, tend to deform by creep so that they no longer have stiffness, and can no longer perform their function at rest. After a few weeks or months, which corresponds to the period between the manufacture of the dispensing device for sale to the consumer, the plastic spring has lost its stiffness, and the sealing of the outlet valve is no longer ensured.
  • the operation of the dispensing device would however be acceptable, since the spring would still retain sufficient stiffness to bring the movable member close to its seat, without guaranteeing the seal. This is the reason why it has not yet been marketed dispensing device incorporating a plastic spring. Thanks to the present invention, this is now possible, since it is not the elastic means (or spring) which ensure the biasing of the movable member against the outlet valve seat.
  • the elastic means can thus retain all their stiffness in the period between the manufacture of the dispensing device until its sale to the consumer.
  • the support means have almost no elasticity, so that the force exerted by the bearing means on the movable member is constant over time. Only when the user wants to use the dispensing device that the elastic means will be implemented. After actuation of the device, the user returns the device to its locked position, wherein again the elastic means no longer ensure the sealing of the outlet valve.
  • the switching between the locked position and the position of use can be generated by a relative displacement between at least a portion of the outlet valve and the elastic means.
  • the relative displacement is a rotation.
  • a translational movement, or a combined rotary / translational movement is also possible.
  • the dispensing device further comprises a pusher on which the user presses to actuate the dispensing device, the pusher being rotated to switch from one position to another.
  • the elastic means exert a force along an axis X, the movable member of the valve being urged against the seat in the direction of the axis X.
  • the elastic means comprise at least two elastic elements distributed around the axis X
  • the support means comprise at least two support elements distributed around the axis X.
  • the elastic elements and the support elements can thus be distributed alternately around the X axis in the form of a crown.
  • the elastic means and the support means are made integrally of plastics material.
  • the elastic means and the support means may constitute a separate part or be made integrally with another constituent element of the dispensing device, such as for example the body of the device intended to be mounted on a reservoir.
  • the movable member is secured to at least one contact zone bearing on the elastic means or the support means.
  • the movable member is integrally formed with at least one axial lug defining said at least one contact zone.
  • a principle of the present invention is to use the locking mechanism already known in the prior art to fulfill a new function, namely that of sealing the outlet valve at rest.
  • the non-resilient rigid support of the lock is thus used to constantly urge the movable member against its seat.
  • FIG. 1 and 2 we will first refer to Figures 1 and 2 to describe the general structure of a dispensing device according to a first embodiment of the invention.
  • the dispensing device in this illustrative example, is a pump, but it could also be a valve.
  • a pump as a dispensing device, without limitation.
  • the pump of Figures 1 and 2 comprises 4 constituent elements, plus an optional element, namely a body 1, a pusher 2, a piston member 3, a biasing member 4 and a protective cover 5 which is optional. All these elements can be made by injection / molding plastic material. Alternatively, some elements may be made of metal, such as the protective cover 5.
  • the dispensing device is intended to be associated with a fluid reservoir (not shown) to together constitute a fluid dispenser.
  • the body 1 comprises an attachment ring 11 intended to engage, for example snapped or screwed, with an opening of a reservoir fluid product that can be in the form of a protruding neck.
  • the ring 11 can engage around the neck, or alternatively inside the neck. It is essential that the fixing of the ring 11 on the opening of the tank is solid and watertight.
  • the body 1 also forms a sleeve 12 which extends in this example in the extension of the ring 11.
  • the sleeve 12 defines near its upper free end an annular bead of abutment 13 which can be continuous or discontinuous.
  • the sleeve 12 defines at its upper end an inner annular housing 14 for receiving the cover 5.
  • the cover 5 has near its free lower end a shoulder 53 facing downwards and an internal flange 54 having a snap-fitting bead adapted to be housed in the housing 14 formed by the sleeve 12.
  • the shoulder 53 and the flange 54 are formed in the wall thickness of the hood 5.
  • the shoulder 53 can come into sharp and clear abutment on the upper edge of the sleeve 12 without revealing the inner flange 54 snapped into the housing 14. This is an interesting feature that can be protected independently and implemented on any type of fluid dispenser.
  • the body 1 also defines a fluid product inlet 15 from the reservoir (not shown).
  • the upper end of the duct 15 forms an inlet valve seat 16.
  • Around the duct 15 extends a sliding shaft 17 which cooperates with the piston element 3, as will be seen below.
  • the barrel 17 extends concentrically around the duct 15 and concentrically inside the bushing 12. A substantially cylindrical annular space is thus defined between the bushing 12 and the barrel 17. This space accommodates both the loading part 4 and the lower end of the pusher 2.
  • the pusher 2 comprises a bearing surface 21 on which the user can press with the aid of one or more finger (s).
  • the pusher comprises a substantially cylindrical lateral skirt whose lower end is formed with an external reinforcement 26 which is housed inside the sleeve 12. The reinforcement 26 can cooperate with the cord 13 to forming a stop, thus defining the rest position of the pump.
  • the bearing surface 21 internally defines an annular seat 22 for the outlet valve of the pump.
  • the skirt 23 forms a dispensing orifice 24 which passes through the wall thickness of the skirt.
  • the orifice 24 is located near the valve seat 22. Below the orifice 24, the skirt 23 forms a sliding section 25.
  • the piston member 3 is a one-piece piece which is housed inside the pusher 2.
  • the piston member 3 comprises a main piston lip 32 sealingly engaged in the barrel 17 and a differential piston lip 35 engaged. sliding in the sliding section 25 of the skirt of the pusher. These two lips 32 and 35 are connected together by an axial trunk 31 traversed by a passage duct 33.
  • the piston member 3 also forms a movable outlet valve member 36 adapted to cooperate with the valve seat 22 to form together the outlet valve of the pump.
  • the movable member 36 is in the form of an annular ring intended to engage around the annular seat 22.
  • the outlet valve defines the outlet of the pump chamber C which is defined on either side of the In fact, part of the chamber C is formed between the piston element 3 and the bearing surface 21, and another part of the chamber C is formed inside the drum 17.
  • the two chamber parts communicate with each other through the passage conduit 33.
  • the piston element 3 forms a movable inlet valve member 34 adapted to cooperate with the seat 16 formed by the body 1. In the two positions represented on the Figures 1 and 2 , the closed outlet valve prevents any communication between the chamber C and the dispensing orifice 24. In contrast, the inlet valve is open and communicates with the reservoir.
  • the piston element 3 further comprises one or more thrust transmission element (s) which is here in the form of axial lugs 37 which extend downwards around the trunk 31 from the section connecting the trunk 31 to the lip 35 and to the movable member 36.
  • the axial tabs 37 are located radially substantially at the same level that the movable member 36.
  • the free lower ends of the tabs 37 define contact zones 38 adapted to come into contact with the biasing part 4.
  • the purpose of the biasing part 4 is to urge the movable member 36 of the outlet valve towards its valve seat 22.
  • the bias exerted by the part 4 is transmitted to the movable member 36 by the axial tabs 37, which thus fulfill a thrust transmission function.
  • the biasing part 4 exerts either an elastic bias or a rigid non-elastic bias.
  • the biasing part 4 is in the form of a substantially cylindrical sleeve comprising six segments separated by slots 44. These six segments are connected together by a common base 40. Of these six segments, there are three resilient members 42 and three rigid support members 41. The elastic members 42 and rigid 41 are alternately arranged so that each elastic member is adjacent to two rigid members, and vice versa. At their free ends opposite the common base 40, the elastic elements 42 form a bearing zone 421. Similarly, the rigid support elements 41 define bearing zones 411. The bearing zones 411 and 421 together define the upper edge of the biasing piece 4, as can be seen on the figure 4 . This edge is, however, interrupted by the slots 44. The bearing areas 411 are further provided with two bosses 412 projecting from the bearing zone 411. It will be readily understood that the rigid support elements 41 are not not axially deformable, while the elastic elements 42 may undergo elastic axial deformation by pressing on their bearing surfaces 421. The three bearing elements 42 and fulfill a function of spring or elastic means by axial support.
  • the biasing piece 4 is arranged around the barrel 17 in the space formed between the sleeve 12 and the barrel 17.
  • the common base 40 of the biasing piece 4 bears on a connecting flange connecting the sleeve 12 to the barrel 17, as can be seen from the Figures 1 and 2 .
  • Support surfaces 411 and 421, respectively belonging to the elastic elements 42 and the rigid support elements 41, are located just below the axial tabs 37 formed by the piston member 3.
  • the figures 1 and 3 represent the pump in a locked position in which it is not possible to operate the pump.
  • the figures 2 and 5 represent the pump in a position of use, which can still be described as a rest position from which the pump can be actuated.

  • the pusher 2 is in abutment against the cord 13.
  • the relative angular positions between the piston element 3 and the biasing part 4 are different.
  • the bearing surfaces 38 of the axial lugs 37 of the piston member 3 are in contact with the bearing areas 411 of the rigid support elements 41.
  • the contact between the legs 37 and the elements support 41 is pressed so that a force is exerted by the support elements 41 on the tabs 37 which transmit this force on the movable member 36 which is in turn strongly pressed against the outlet valve seat 22
  • the support elements 41 are rigid, and therefore non-elastic and non-deformable, the pressure exerted on the tabs 37 and on the movable member 36 is constant. Because the support elements 41 are elastically deformable, it is not possible to move the pusher axially 2, and thus actuate the pump.
  • rotating securing means such as those provided at the upper end of the piston member 3 and the lower face of the bearing surface 21. These means for securing in rotation its referenced respectively 39 and 29 in the figures.
  • a rotation of the pusher 2 causes a rotation of the lugs 37 of the piston element 3, which has the effect of moving the lugs of the bearing zones 411 of the support elements 41 to the level of the zones of support 421 of the elastic elements 42.
  • the contact surfaces 38 of the tabs 37 must pass over the bosses 412. The passage on these bosses is perceptible by the user who knows as he moved from one position to another.
  • the pump of the invention is switchable between a locked position, in which the outlet valve is biased in the closed position by the rigid support means 41, and a position of use, but nevertheless of rest , in which the outlet valve is biased in closed positon by resilient means which will then perform a normal function of return spring or precompression during the actuation of the pump.
  • the elastic means remain completely at rest in the locked position. In this way, they are only subjected to stress for a very short period, which corresponds to the periods of actuation of the pump. In any case, between the manufacture and the first use of the pump by the user, the pump is in the locked position.
  • the switching between the locked position and the position of use is effected by a relative rotation between the biasing member 4 and the piston member 3.
  • the switching between the locked and use positions is generated by another type of displacement, for example translational or a combination of a translational and rotary displacement.
  • the biasing part 4 has been presented as a separate part reported inside the pump. However, without departing from the scope of the present invention, it is conceivable to form the biasing part 4 integrally with the body 1 or the piston member 3.
