Definitions

  • the present invention relates to a dispenser of a product, in particular a cosmetic product, comprising a rotary operating member.
  • dispensers comprise 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 mounted for rotation in the container and passing through a threaded orifice of the piston.
  • the stick is linked to the piston and by turning the operating member in an appropriate direction, the piston moves under the action of the rotation of the drive screw towards the open end of the cylindrical body to bring out the product bread and allow product to be collected by friction.
  • the piston moves in the opposite direction to return the product roll and allow the establishment of a closure cover on the container.
  • a first solution consists in first mounting inside the container the drive screw and then engaging the orifice threaded piston on the free end of the screw. The piston is then moved towards the inside of the container by turning the operating member.
  • This solution can prove to be difficult to implement when the operating member is constituted by a wheel which is accessible only through windows made in the base of the container, which reduces the accessible gripping surface and increases the number of operations required to turn the dial.
  • 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 an orifice of the piston provided connecting means capable of transforming a rotational movement of the screw into an axial displacement of the piston, said screw being able to be driven in rotation by an operating member accessible to the user.
  • the object of the invention is in particular to make the manufacture of the dispenser even easier.
  • connection means being radially deformable, they are arranged to deform radially in contact with the thread of the screw when the relative axial displacement of the connection means and of the screw is forced so as to let escape the latter.
  • 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 make the piston with a removable central part.
  • the connecting means are preferably elastically deformable and advantageously comprise at least two sectors having a cylindrical internal threaded surface and connected to the rest of the piston so as to be able to move away from one another.
  • 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 in the bottom stop simply causes the locking of the wheel urged in rotation in the wrong direction. .
  • the tendency being to use actuators having in cross section an elongated shape in order to transmit a greater torque to the screw and to allow a greater axial displacement of the piston at each revolution of the actuator the torque exercised in this case by the user in the event of blocking in the lower stop of the piston is then liable to cause the screw to break.
  • the invention makes it possible to use an operating member having an elongated shape in cross section without risk of damaging the screw in the event of rotation in the wrong direction of the operating member.
  • the aforementioned sectors have an elongated shape along the axis of the screw and are connected to the piston at one end.
  • said sectors are returned radially inwards by an elastically deformable return member which exerts its return action at least at the free end of said sectors.
  • this return member is in the form of a ring or a sleeve of elastomeric material surrounding said sectors at least at their lower part.
  • the return member may be in the form of material bridges extending between said sectors.
  • These material bridges can be made in one piece and in the same material as said sectors or be made of an elastomeric material.
  • the cylindrical body of the container has at least one stop to limit the depression stroke of the piston inside the container.
  • the operating member is molded at least 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 being able to rotate freely in the latter.
  • the drive screw has a pitch of between 2 and 16 mm, and preferably between 4 and 7 mm, which makes it possible to obtain, with each rotation of the operating member, a relatively large displacement of the piston.
  • FIG. 1 a dispenser 1 according to a particular embodiment of the invention.
  • This dispenser 1 comprises a container 2 with cylindrical body 3, of axis X and having an oval cross section.
  • the invention is not limited to this particular shape of the cross section.
  • the cylindrical body 3 is open at its upper part 4 and has, in the vicinity of this upper opening, a wall of reduced thickness to constitute the seat of a closure cover 5.
  • the distributor 1 also comprises a piston 6, the cross section of which corresponds precisely to the internal section of the cylindrical body 3, so that it is immobilized in rotation in the cylindrical body 3.
  • the piston 6 can move axially in translation with the inside of the cylindrical body 3.
  • a drive screw 7 is mounted to rotate freely around the axis X 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 into a translation of the piston 6 along the axis X inside the cylindrical body 3.
  • the piston 6 supports a stick S, that is to say a solid bread, for example a body deodorant.
  • a stick S that is to say a solid bread, for example a body deodorant.
  • the product can then be taken out by a dome pierced with multiple outlet orifices and fitted into the upper opening of the cylindrical body 3.
  • the piston 6 has 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 an operating member 9 accessible to the user on the side opposite to the opening of the cylindrical body 3.
  • the operating member 9 has a transverse wall 11 made in one piece by molding plastic with the screw 7.
  • An external skirt 10 is snapped onto an internal skirt 32 extending downwardly at its periphery the wall 11.
  • the external skirt 10 constitutes a gripping surface allowing the user to grasp the operating member and rotate it around the X axis. Because the external skirt 10 has an elongated shape in cross section, it is possible to transmit a torque to the operating member 9 important.
  • the external skirt 10 is closed below by a bottom 31.
  • the transverse wall 11 is extended upwards in its central part by a cylindrical skirt 12.
  • the latter is provided on its radially external surface with a retaining groove 13 annular allowing its fixing by snap-fastening in a chimney 14 extending towards the interior of the container and formed in the lower part of the latter.
  • the chimney 14 is provided on its radially internal surface with an annular rib 15 intended to be housed in the retaining groove 13 at the end of the insertion of the skirt 12.
  • the skirt 12 advantageously comprises at least one axial slot 34 intended to facilitate the elastic crossing of the annular rib 15 by the free end of the skirt 12 during assembly of the member operation 9 and container 2.
  • the bottom 31 is provided internally with an annular sealing lip 33 which adjusts in the skirt 12 in order to seal it after the container 2 has been filled, as will be explained below.
  • the screw 7 is connected at its lower end to the base 16 of a cone 17 converging in the direction of the skirt 12 and fixed to the latter by three oblique connecting tabs 18, equally spaced around the axis X.
  • a gasket 19 is housed in a shoulder formed at the base of the chimney 14 to be interposed between the latter and the skirt 12 in order to avoid an entry of air through the lower part of the container 2 and degradation of the product contained inside.
  • Reliefs 21 can be produced on the upper face of the transverse wall 11 in order to engage in recesses of suitable shape 22 formed on the lower face of the container 2 in order to create a point of resistance in the rotation of the member for operation 9 and allow a user to easily position it 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 the piston 6. It will be noted 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 connecting means 8 is situated slightly above the base 16 of the cone 17.
  • connection means 8 With particular reference to FIGS. 2 and 3.
  • connection means 8 comprise in the embodiment described two sectors 25 separated by two diametrically opposite axial slots 26 and a ring 27 made of an elastomeric material surrounding the lower part of the 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 produced by molding in one piece with the latter.
  • the sectors 25 are threaded on their radially internal face so as to be able to engage on the thread of the screw 7 and transform a rotational movement of the latter into an axial displacement of the piston 6, in the manner of a screw jack .
  • the hollow threads formed on the sectors 25 have been referenced 28.
  • the relief thread of the screw 7 bears the reference 29.
  • the sectors 25 can move apart in order to cross the thread of the screw 7 when the piston is not free to move inside the cylindrical body 3 because bearing against the ribs 20, or when a thrust is exerted on the piston 6 to move it down.
  • the separation of the sectors 25 causes the ring 27 to stretch initially initially at rest, which exerts a restoring force increasing with the distance separating the lower ends of the sectors 25.
  • connection means 8 which has just been described.
  • the connecting means shown in FIG. 8 can advantageously be made by bi-injection, that is to say by injection molding in a first plastic material, relatively rigid, of the cylindrical sectors 25 ′ and of the transverse wall 24 of the piston and by injection molding of the material bridges 27 ′′ in an elastomeric material, which binds to the first plastic material by local fusion.
  • a pair of materials which can be used mention may be made of a polyolefin / EPDM, polystyrene / styrene ethylene-butadiene styrene pair.
  • the distributor 1 To assemble the distributor 1, one starts by fixing the operating member 9 by introducing the screw 7 then the skirt 12 into the chimney 14 until it snaps onto the annular rib 15.
  • the operating member 9 is positioned with the internal skirt 32 substantially in the continuity of the cylindrical body 3 of the container 2.
  • the piston 6 is brought into the opening of the cylindrical body and then lowered onto the screw 7 by a thrust exerted parallel to the axis X.
  • the screw 7 escapes the connecting means 8.
  • the product S is a solid bread, it is advantageously put in place by pouring it in liquid form, the container 2 being upside down, by the skirt 12.
  • the closing cover 5 is in place on the container.
  • the openings formed in the transverse wall 24 allow the product to fill the space located in the container 2 on the side of the opening 4 of the cylindrical body 3.
  • the height of product is chosen so as to slightly cover the transverse wall 24, this which secures the stick and the piston 6 when the product cools. Then, the external skirt 10 of the operating member is snapped onto the internal skirt 32.
  • 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 exert, when the product is collected, - sufficient force on the screw 7 to prevent the piston from sinking inside the container, the push to be exerted on the piston to cause the escape of the screw being chosen significantly greater than the force normally exerted on the piston when the stick is moved over the skin.
  • the screw 7 can escape the connection means without the user having to act on any unlocking member.
  • the connecting means 8 deform themselves in contact with the screw when the relative axial displacement of the connecting means and the screw is forced.
