Definitions

  • the present invention relates to a distributor of a product, in particular a cosmetic product, comprising an operating member rotary.
  • dispensers have a cylindrical container open at one of its ends, a piston movable axially in translation in this body and a drive screw mounted at rotation in the container and passing through a threaded orifice piston.
  • the stick is linked to the piston and by turning the maneuver in an appropriate direction, the piston moves under the action rotation of the drive screw towards the end open of the cylindrical body to take out the product bread and allow the product to be collected by friction. While turning the operating member in the opposite direction, the piston moves in the opposite direction to bring in the product bread and allow the installation of a closure cover on the container.
  • a first solution is to climb inside the container the drive screw 'and then engage the hole threaded piston on the free end of the screw. The piston is then moved towards the inside of the container by turning the maneuver.
  • This solution can be difficult to implement when the operating member is constituted by a wheel which is only accessible through windows made in the base of the container, which reduces the accessible gripping surface and increases the number of manipulations required to rotate the wheel.
  • connection means comprise two branches coming normally engaged on the screw, and a pivoting lever connected to a actuation mechanism to spread the branches when is necessary to uncouple the piston and the drive screw.
  • Such a device is of relatively complex construction and expensive.
  • the object of the present invention is to further improve a dispenser of the type comprising a container with a cylindrical body open at one of its ends, a piston movable axially in translation in this body and a drive screw passing through a orifice of the piston provided with connecting means capable of transforming a rotational movement of the screw in an axial displacement of the piston, said screw can be rotated by a member of maneuver accessible to the user.
  • the object of the invention is in particular to make it even easier the manufacture of the distributor.
  • said means of connection being radially deformable, they are arranged to deform radially in contact with the thread of the screw when the relative axial displacement of the connecting means and the screw so as to let the latter escape.
  • the assembly of the dispenser is facilitated since the piston can be pushed inside the container without it being necessary to turn the operating member or to realize the piston with a removable central part.
  • the connecting means are preferably elastically deformable and advantageously comprise at least two sectors having a threaded cylindrical internal surface and connected to the rest of the piston so that it can move away from each other.
  • the operating member When the operating member is constituted by a wheel of circular section, the torque exerted by the user on the screw remains relatively low and the presence of the piston at the bottom stop simply causes the locking of the wheel requested to rotate in the wrong way.
  • the trend is to use operating members having a cross-sectional shape elongated in order to transmit greater torque to the screw and allow a greater axial displacement of the piston at each revolution of the operating member, the torque exerted in this case by the user in the event of blockage in the lower stop of the piston is then likely to cause the screw to break.
  • the invention makes it possible to use a maneuver having in cross section an elongated shape without risk of screw damage if rotated incorrectly sense of the operating member.
  • the aforementioned sectors have an elongated shape along the axis of the screws and are connected to the piston at one end.
  • said sectors are recalled radially inwards by a elastically deformable return member which exerts its action of recall at least at the free end of said sectors.
  • These material bridges can be made in one piece and in the same material as said sectors or be made in an elastomeric material.
  • the operating member has come from molding to less partially in one piece with the screw.
  • the latter came from molding in one piece with a skirt shaped to snap into a chimney of the container and can rotate freely in it.
  • the invention also relates to a manufacturing process according to claim 18.
  • FIG. 1 There is shown in Figure 1 a distributor 1 according to a particular embodiment of the invention.
  • This dispenser 1 comprises a container 2 with a cylindrical body 3, of axis X and having an oval cross section. Well heard the invention is not limited to this particular form of cross section.
  • the distributor 1 also includes a piston 6, the straight section corresponds precisely to the internal section of the body 3 cylindrical, so that it is immobilized in rotation in the cylindrical body 3.
  • the piston 6 can move axially in translation inside the cylindrical body 3.
  • a drive screw 7 is mounted free to rotate around of the X axis inside the container 2, being immobilized axially. This screw extends substantially over the entire height of the cylindrical body 3.
  • Connection means 8 are provided for transforming a rotational movement of the screw 7 in translation of the piston 6 along the X axis inside the cylindrical body 3.
  • the piston 6 supports a stick S, i.e. a solid bread, for example a deodorant body.
  • a stick S i.e. a solid bread
  • the product can then be removed by a dome pierced with multiple outlets and attached in the upper opening of the cylindrical body 3.
  • the piston 6 comprises a side wall 23 and a perforated transverse wall 24, linked to the stick S.
  • the screw 7 is secured at its lower end to a member maneuver 9 accessible to the user on the side opposite the opening of the cylindrical body 3.
  • the member maneuver 9 has a transverse wall 11 made in one holding by plastic molding with screw 7.
  • a skirt outer 10 is snapped onto an inner skirt 32 extending towards the bottom at its periphery the wall 11.
  • the external skirt 10 constitutes a gripping surface allowing the user to grasp the organ maneuver and rotate it around the X axis. Because the outer skirt 10 has a cross-sectional shape elongated, it is possible to transmit to the operating member 9 a significant couple.
  • the outer skirt 10 is closed below by a bottom 31.
  • the transverse wall 11 is extended upwards in its central part by a skirt cylindrical 12.
  • the skirt 12 has advantageously at least one axial slot 34 intended to facilitate the elastic crossing of the annular rib 15 by the end free of the skirt 12 during assembly of the operating member 9 and container 2.
  • the bottom 31 is provided internally with an annular lip sealing 33 which fits in the skirt 12 to close it so waterproof after filling the container 2, as will be specified in the following.
  • Screw 7 connects to its lower end on the base 16 of a cone 17 converging in the direction of the skirt 12 and fixed to the latter by three oblique connecting lugs 18, equally distributed around the X axis.
  • Reliefs 21 can be produced on the upper face from the transverse wall there to come and engage in recesses of suitable shape 22 formed on the underside of the container 2 in order to create a point of resistance in the rotation of the organ of maneuver 9 and allow a user to easily position the latter in the extension of the cylindrical body 3 of the container.
  • the container 2 is internally provided with ribs 20 to limit the downward stroke of piston 6. Note that when the piston 6 rests by the side wall 23 in bottom stop on the end upper ribs 20, the lower end of the means of link 8 is located slightly above the base 16 of the cone 17.
  • the connecting means 8 comprise in the example of embodiment describes two sectors 25 separated by two axial slots 26 diametrically opposed and a ring 27 made of an elastomeric material surrounding the lower part of sectors 25.
  • the sectors 25 are connected at their upper end to the threads of material constituting the transverse wall 24 of the piston 6 and are made by molding in one piece with the latter.
  • the sectors 25 are threaded on their radially internal face of so as to be able to engage on the thread of the screw 7 and transform a rotational movement of the latter in an axial displacement piston 6, like a screw jack.
  • the relief net of the screw 7 bears the reference 29.
  • Sectors 25 which are only connected to the transverse wall 24 that by their upper end, tend to pivot each around a geometric axis of rotation which is perpendicular to the X axis and parallel to the plane joining the slots 26.
  • the spacing sectors 25 causes ring 27 to stretch initially at rest, which exerts a restoring force-increasing with distance separating the lower ends of the sectors 25.
  • the connecting means shown in Figure 8 can advantageously be made by bi-injection, that is to say by injection molding in a first plastic material, relatively rigid, cylindrical sectors 25 'and the wall 24 of the piston and by injection molding of the bridges material 27 "in an elastomeric material, which binds to the first plastic material by local fusion.
  • a polyolefin / EPDM pair can be used, polystyrene / styrene ethylene-butadiene styrene.
  • the piston 6 is brought into the opening of the body cylindrical then lowered onto screw 7 by a thrust exerted parallel to the X axis.
  • the screw 7 escapes the means 8.
  • the threads 28 are normally engaged on thread 29 of the screw 7, and the ring 27 is no longer stressed in this relative position of the piston and of the operating member. So it keeps all its elasticity even in the event of prolonged storage before use.
  • the user removes the cover 5 and raises the product by turning the operating member 9.
  • the product is removed by friction.
  • the connecting means exercise, when the product is collected, sufficient force on the screw 7 to prevent the piston from sinking inside the container, the thrust to exert on the piston to cause the escape of the screw being chosen significantly larger than the force normally exerted on the piston when the stick is moved on the skin.
  • the screw 7 can escape the connection means without the user has to act on any unlocking member.
  • the connecting means 8 deform themselves on contact of the screw when the relative axial displacement of the means is forced connection and screw.
