Definitions

  • the present invention relates to a fluid dispenser member for mounting on a fluid reservoir fluid to collect fluid.
  • the invention also relates to a fluid dispenser essentially consisting of such a dispensing member and its associated fluid reservoir. This type of dispensing member is frequently used in the fields of perfumery, cosmetics or even pharmaceuticals to produce dispensers of fluid product with manual or repeated operation at a rapid rate.
  • the dispensing member is a pump or a valve comprising a fluid product distribution chamber of variable volume.
  • the chamber conventionally comprises an inlet valve through which the chamber communicates with the reservoir.
  • the chamber also comprises a piston displaceable by pressing a pusher to vary the volume of the chamber and thus put the fluid contained in the chamber under pressure.
  • the piston is generally biased to the rest position by return spring means.
  • an outlet valve allows the fluid under pressure to exit the chamber to flow to a dispensing orifice.
  • the outlet valve comprises a valve seat and a movable valve member movable to come into sealing contact with its seat. When the pressure is sufficiently high in the chamber, the movable member is detached from its seat and thus clear an outlet passage for the fluid under pressure. This is a very classic design for a pump.
  • resilient material comprises a central portion, a peripheral portion and a stretchable elastic joining portion connecting the central portion to the peripheral portion.
  • the central portion rests on a socket forming an inlet opening.
  • the central portion forms a kind of elastically deformable tongue that selectively rests tightly on the inlet opening.
  • the tongue and the hole together form the inlet flap.
  • the connecting part serves as a return spring.
  • each part of the elastically deformable part defines a proper function, namely that of the inlet valve for the central part, of the return spring for the connecting part and the flap output for the peripheral part.
  • the present invention aims to define a dispensing member whose functional distribution is different. Another object is to provide a dispensing member whose dispensing orifice is fixed, that is to say independent in displacement of the actuating pusher.
  • the present invention proposes a fluid product dispensing member intended to be mounted on a fluid reservoir for taking fluid from it, said dispensing member comprising a fluid volume distribution chamber of variable volume, said chamber comprising an inlet valve through which the chamber is intended to be placed in fluid communication with the reservoir, said valve comprising a seat and a movable member, a piston displaceable by pressing on a pusher to vary the volume of the chamber and thus putting the fluid contained in the chamber under pressure, said piston being biased in the rest position by return spring means, and an outlet valve through which the fluid under pressure leaves the chamber to flow to a dispensing orifice, said valve comprising a valve seat and a movable valve member adapted to move in sealing contact he and out of contact of said seat, characterized in that the return spring means and the movable outlet valve member are formed by one and the same element.
  • the element is deformable by elastic stretching.
  • the outlet valve seat can be fixed relative to the seat of the inlet valve. Additionally or alternatively, the outlet valve seat may be movable relative to the pusher.
  • the element comprises a wall in sealing contact with the seat, said wall sliding tightly on the seat.
  • the element comprises a fixed end secured to anchoring means and a movable end, the piston being secured to the movable end.
  • the piston and the element are made integrally.
  • the seat is annular, the element sliding tightly inside the seat.
  • the element is formed by a sleeve which is elastically stretchable, substantially cylindrical and elastically deformable inwardly.
  • the sleeve comprises an outer wall adapted to come into sealing sliding contact with a peripheral annular seat which surrounds the sleeve.
  • the sleeve is formed by a one-piece piece also forming the piston and anchoring means.
  • the sleeve comes into pressed contact with increasing force on the seat as it is further stretched.
  • the sleeve may be in the form of a substantially cylindrical or frustoconical tube section whose outer wall comes into contact with an outer peripheral annular seat.
  • the present invention also relates to a fluid dispenser comprising a fluid reservoir and a dispensing member as defined above. '
  • the dispensing member is a pump.
  • the spirit of the invention which will be defined hereinafter can also be applied to a valve.
  • the fluid dispenser that integrates the dispensing member of the invention essentially comprises a container 2 associated with said dispensing member of the invention.
  • the container 2 defines a tank drum 21 which is formed over most of its height with a substantially cylindrical cross section which is not necessarily circular.
  • the barrel 21 internally forms a sealed sliding wall.
  • a scraper or follower piston 24 is disposed inside the barrel 21 and this piston 24 is intended to move with a sliding contact sealing against the inner wall of the barrel 21.
  • the barrel 21 and the follower piston 24 together define a reservoir 20.
  • This reservoir is here of variable volume since the piston 24 will move in the drum 21 so as to reduce the useful volume of the reservoir 20.
  • the container 2 comprises a lower end 23 and an upper end
  • the neck defines an opening often of reduced section relative to the barrel 21.
  • Figures 1 and 2 show the reservoir 20 with a maximum volume.
  • the piston 24 is then located near the lower end 23 of the barrel 21.
  • the lower end 23 may be provided with a bottom 25 advantageously pierced with one or more holes for communicating the space between the piston 24 and the bottom 25 with the outside.
  • the fluid product occupies the space formed between the piston 24 the barrel 21 and the neck 22.
  • the piston 24 moves by suction towards the neck 22, which has the effect to reduce the useful volume of the reservoir 20.
  • This is a conventional piston system, frequently used for sensitive fluid products that can deteriorate in contact with air.
  • the advantage with this type of tank is precisely that the fluid product is never in contact with the outside air.
  • the dispensing member according to the invention can be used with other types of tank, such as for example flexible bags freely deformable or more conventional containers in the form of bottles or rigid bottles.
  • the dispensing member 1 comprises a body made here in two parts, namely a base 11 and a cap 12.
  • the body is made in two parts for reasons of simplicity of molding. Indeed, it is not excluded that the body can be made in one piece.
  • the dispensing member also comprises a piece of elastic material 13, a pusher 14 and a movable member of the inlet valve 15. It can thus be said that the dispensing member is made from five separate pieces.
  • the base 11 forms a chamber shaft 111 which is here circular cylindrical in shape, but which may be of different shape, that is to say non-circular and even non-cylindrical.
  • This chamber shaft 111 is extended downwardly by an inlet sleeve 114 which defines a fluid product inlet passage.
  • This sleeve 114 forms an inlet valve seat 115.
  • the sleeve 114 accommodates a movable inlet valve member 15.
  • This movable member 15 in association with the seat 115 together form the inlet valve of the pump.
  • the movable member 15 is formed by a plastic piece forming a corolla sealingly abuts on the seat 115. This is only a particular embodiment that has no limiting scope.
  • the particular shape of the inlet valve is not critical for the present invention, and any input valve can be used in the invention.
  • the chamber shaft 111 is extended upwards by an annular flange 112 which extends radially outwards. This flange 112 is then extended downwards by a fixing ring 113.
  • This fixing ring 113 is intended to engage with the neck 22.
  • this socket is a latched engagement: the ring 113 forms a detent head intended to engage below a peripheral flange formed by the neck 22.
  • the ring 113 does not even need to be made in one piece with the chamber shaft 111. A fixation by screwing or crimping is also possible.
  • the base 11 also forms an attachment sleeve 116 which extends upwardly in the extension of the ring 113.
  • This attachment sleeve 116 can advantageously be formed only with angular sleeve sections so as to form crenellations.
  • the attachment sleeve 116 thus consists of several angular segments separated by slots.
  • the cap 12 comprises an outer skirt 121 intended to engage advantageously snapped with the ring 113.
  • the skirt can bear against the container 2.
  • the skirt 121 surrounds the ring 113.
  • the skirt 121 forms a dispensing nozzle 126 which defines a dispensing orifice 127.
  • the skirt 121 also comes into contact with the fixing sleeve 116.
  • the cap 12 comprises an inner sleeve 122 which concentrically extends inside the skirt 121.
  • the sleeve 122 and the skirt 121 are connected together at their upper ends.
  • the skirt 121 and the sleeve 122 form between them an annular which forms an outlet channel section 129 which communicates with
  • the bushing 122 extends downwardly through a bottom flange 128.
  • the bottom flange 128 supports a guide bushing 123 which extends upwardly. Still further inside, the bottom flange 128 is connected to a support sleeve 124. This sleeve 124 extends upwardly but also downwardly relative to the bottom flange 128.
  • the support sleeve 124 has at least one cutout 124 'in the form of a longitudinal vertical slot. This slot 124 'extends below the bottom flange 128. Below this slot 124', the support sleeve 124 forms an annular bead 125 which extends radially inwardly. This bead 125 forms a kind of protuberance with respect to the inner wall of the support sleeve 124.
  • the end of the support sleeve 124 engages with the upper end of the chamber shaft 111 formed by the base 11. contact between the support sleeve 124 and the base 11 is preferably sealed.
  • the bottom flange 128 remains spaced from the annular flange 112 so as to form another section of the outlet channel 129. This section 129 is connected directly to the dispensing orifice 127. It can be said that the support sleeve 124 extends substantially the chamber shaft 111 and provides a lateral outlet through the slot 124 which then communicates via the outlet channel 129 to the nozzle 126 forming the dispensing orifice 127.
  • the piece of elastic material 13 comprises an anchor ring 136, an elastically stretchable sleeve 131 and a piston 135.
  • the piece of elastic material 13 is made integrally.
  • the anchor ring 136 engages on the upper part of the support sleeve 124.
  • the ring 126 can form a lip which extends between the sleeve 123 and the sleeve 124.
  • the anchoring ring 136 is thus integral with the
  • the sleeve 131 comprises an upper end 132 connected to the ring gear 136 and a lower end 133 connected to the piston 135.
  • the sleeve 131 extends inside the sleeve 124 and the chamber shaft 111 and the piston 135 is located inside the chamber shaft 111.
  • the sleeve 131 has a stretch deformation characteristic so that the length or height of the sleeve can vary considerably.
  • the sleeve also has radially deformable inward and outward characteristics. More simply, the sleeve can be likened to a section of elastically stretchable pipe of substantially cylindrical or frustoconical shape. In the case shown in the figures, the sleeve has a slightly frustoconical shape: in fact, the section of the sleeve at its upper end 132 is slightly greater than that at its lower end 133.
  • the sleeve 131 and the piston 135 do not need to come into sealed contact inside the chamber shaft 111. Indeed, a gap may remain between the piston and the barrel.
  • the sleeve 131 extends inside the support sleeve 124, its outer wall 130 is brought into peripheral contact with the cord 125. According to the invention, this contact is sealed.
  • the barrel 111, the lower portion of the sleeve 124 extending from the cord 125, the lower portion of the sleeve 131, the piston 135 and the movable member 15 of the inlet valve together form a chamber distribution 10 of variable volume.
  • the displacement of the piston 135 in the barrel 111 by more or less stretching the sleeve 131 varies the internal volume of the distribution chamber 10.
  • the dispensing member comprises a pusher 14 forming a bearing surface 141 bordered by a retaining skirt 144 engaged around the guide sleeve 123.
  • the pusher 14 also comprises a rod actuation 142 which is engaged with the piston 135. It is easily understood that by pressing on the bearing surface 141 of the pusher 14, the rod 142 is pressed into the sleeve which has the effect of moving the piston 135 towards the valve input. The sleeve is then deformed by elastic stretching and its outer wall 130 slides sealingly against the outer peripheral bead 125.
  • the cuff which although already stretched elastically, will deform radially inwardly by peeling off the bead 125. This has the effect of clearing an outlet passage for the fluid under pressure which can then flow through the slot 124 'and the channel at the outlet 129 to reach the dispensing orifice 127.
  • the outer wall 130 of the sleeve returns in sealing contact against the cord 125.
  • the cord 125 thus fulfills an outlet valve seat function, and the outer wall of the sleeve performs a function of movable outlet valve member for selective sealing engagement.
  • the contact of the outer wall 130 of the sleeve is a dynamic contact since sliding. Indeed, at the beginning of the actuation phase, the piston 135 moves which has the effect of stretching the sleeve 131. The outer wall 130 then moves in sealing contact on or inside the cord 125.
  • the same and unique element namely the sleeve 131, defines, forms or is formed by a zone filling both the function of return spring and movable member of the outlet valve.
  • the arrangement of the sleeve inside the seat allows for a dispenser whose dispensing orifice is fixed relative to the reservoir. Indeed, the displacement of the pusher 14 is completely independent of the dispensing orifice.
  • the outlet valve seat defines a relative throttle point of the sleeve at which the dummy straight line separating the upper end and the lower end of the sleeve is broken.
  • the sealing contact of the outer wall 130 of the sleeve on the seat cord 125 is effected with a constantly increasing support force as the push-button 14 is depressed. In other words, more pressing the pusher 14 and the cuff presses against the seat.
  • the contact between the sleeve and the seat is, however, broken when the pressure reaches a sufficient value inside the distribution chamber 10.
  • the sleeve 131 here extends substantially rectilinear or straight.
  • the outlet valve seat 125 forms a larger throttle, so that the sleeve may have a shape of X or Y. The more the seat throttles the cuff and the pressure threshold more opening of the outlet valve is important.
  • a dispenser according to an embodiment not shown may comprise a deformable member by bending or compression which fills both the functions of spring and outlet valve at a single zone.
