Definitions

  • the invention relates to a device for applying a pasty product, in particular a cosmetic product such as lipstick, presented in the form of grapes and mounted sliding in a case.
  • Such a lipstick grape must be crumbly and is, for this reason, usually of a relatively soft consistency, which causes difficulties in making it integral with a support such as a grape dish, in order to its application on the lips.
  • shocks during transport or vibrations during use can cause the grapes to become fragile at the level of the cup.
  • a more or less significant play of the cup in the case can be observed.
  • a device aimed at reducing the vibrations of the grape during its use is known, in particular, from FIG. 19a of document EP-A-0 658 325.
  • This device comprises: - a tubular slide element in which is slidably mounted a cup intended to receive the product grape and comprising two lugs engaged in longitudinal slides; a cylindrical casing, the internal wall of which is provided with helical grooves, this casing being fitted free in rotation on the tubular element, the lugs of the cup being engaged in the grooves of the casing; - Flexible friction means provided between the cup and the tubular element, these friction means comprising at least one tongue, flexible in the radial direction, provided on the tubular element, and adapted to cooperate with a bearing surface of the cup.
  • Document FR 1 501 043 describes a mechanism for lipstick, comprising, a cup provided with two diametrically opposite lugs and each engaged, on the one hand in an axial slide, and on the other hand in a helical groove.
  • Each lug is provided with a slot, giving it a radial elasticity capable of allowing friction of said lug either in the slide or in the helical groove. This provision does not does not, however, compensate for significant dimensional variations between the lug and the slide and the elasticity of a split lug is, generally insufficient to ensure adequate friction.
  • a mechanism for lipstick comprising a tubular element, provided with a first axial slot, acting as a slide for a lug which is provided with a product cup.
  • the invention aims, in particular, to provide a device of the kind defined above which is of a relatively simple embodiment, and which does not risk, in particular, leading to blocking of the cup.
  • the invention aims to suppress the wobbling and the vibrations appearing during transport and / or during the use of the grape, whatever the position of the grape in the case. Thanks to the invention, the grape of pasty product is then better protected against impact.
  • the device according to the invention for applying a solid, disintegrating product, in particular a cosmetic product such as lipstick, presented in the form of a grape comprises: - a tubular slide element (s) provided with a longitudinal axis, in which a cup intended to receive the grape is slidably mounted, and comprising at least one lug engaged in a corresponding slide delimited by two longitudinal edges; a cylindrical envelope having an internal wall in which at least one helical groove is provided, said tubular element being free to rotate inside the envelope, the lug (s) of the cup engaging in the helix groove (s) of the envelope; - And braking means to ensure flexible friction between the cup and the tubular element.
  • This device is characterized in that the flexible friction is ensured by elastic deformation tangentially to the walls of the tubular element, of at least one of the longitudinal edges of at least one slide at the passage of said lug, the width of which is slightly greater than the width of said slide.
  • the difference between the width of a lug and that of a slide is advantageously between 0.02 mm and 0.3 mm, and preferably between 0.08 mm and 0 , 15 mm.
  • the means for ensuring a gentle friction between the cup and the tubular element consist of one or more longitudinal bands constituting at least one of the edges of the slide (s).
  • this longitudinal strip consists of an elastomeric material.
  • the tubular element can then be produced by bi-injection of two materials: an elastomeric material for the longitudinal strip (s), and a rigid or semi-rigid thermoplastic material for the rest of the element tubular.
  • the strip forming the edge of the slide is made of the same material as the tubular element.
  • at least one slot is formed in the tubular element, over substantially the entire height of the slide (s), said slot delimiting with a corresponding slide an elastically deformable strip delimited on the one hand by an edge longitudinal of the slot, and on the other hand, by a longitudinal edge of the corresponding slide, said strip being able to deform elastically as the lug passes through the slide.
  • this (or these) slot (s) are provided in the vicinity of each of the slides, so as to define for each slide an elastically deformable strip.
  • the width of the strip is approximately 1 mm to approximately 5 mm. Thus one can ensure a constant tightening of the lug in the slide during its entire stroke.
  • the cup is provided with two longitudinal slides, formed parallel to the axis of the tubular envelope, diametrically opposite.
  • the cup has two lugs also arranged diametrically opposite so as to each engage in a corresponding slide.
  • the tubular element may further include a base with a closed bottom, capable of strengthening its rigidity and facilitating its gripping.
  • the base, the tubular element forms axial stop means, suitable for cooperating with a lower end of the cylindrical envelope, so as to limit the axial engagement of the tubular element in said cylindrical envelope.
  • the second end of the cylindrical envelope is in abutment against an external bead, carried by the end opposite the base, of the tubular element.
  • the material used for the cylindrical envelope comprising the helical grooves is chosen from the group of polystyrenes, polyolefins, polyacetals, polyamides, polyesters.
  • the material of the tubular element is advantageously a rigid or semi-rigid thermoplastic material and is preferably chosen from the group of polyolefins, polystyrenes, cellulose acetates and propionates, vinyl polymers, polyacetals, polyamides.
  • an elastomer capable of forming, by thermofusion, a solid bond with the rigid or semi-rigid thermoplastic material is advantageously chosen from the rest of the tubular element.
  • the tubular element in two materials can be produced according to the bi-injection technique.
  • Figure 1 is a vertical axial section of a device according to the invention for applying a grape-shaped lipstick.
  • Figure 2 is a perspective view of the tubular member of the device of Figure 1 and the grape cup.
  • the device D comprises a tubular element 1 with slides 2 constituted by a longitudinal slot of width d 2 , extending substantially from bottom to top in the direction of the generatrices of the element 1.
  • slides 2 constituted by a longitudinal slot of width d 2 , extending substantially from bottom to top in the direction of the generatrices of the element 1.
  • two diametrically opposed slides 2 are planned.
  • a cup 3 of generally cylindrical shape is slidably mounted inside the tubular element 1.
  • the base of the grape B of lipstick is received and held tight in the cup 3.
  • This cup, of cylindrical shape has two lugs 4 diametrically opposite, projecting radially outwards.
  • the lugs 4 are engaged in the slides 2 and pass through these slides, emerging on the outside surface of the tubular element 1.
  • These lugs 4 have a diameter d 1 , slightly greater than the width d 2 of the slide 2.
  • d 1 is of the order of 2.5 mm
  • d 2 is approximately 2.4 mm.
  • this clamping action can correspond to a difference in width d 1 -d 2 of between 0.02 mm and 0.3 mm.
  • Flexible friction means F are provided on the tubular element.
  • these flexible friction means F comprise two flexible strips 8 provided over substantially the entire height of the tubular element 1, each strip 8, of elongated rectangular shape, being delimited on either side other, by the slide 2 and by a longitudinal slot 9 parallel to this slide 2.
  • a single strip 8 is provided, associated with a single slide.
  • a band is provided associated with each slide.
  • the width d 3 of the strip 8 is chosen according to the rigidity of the material used for the production of the tubular element. .
  • the width d 3 of the strip 8 is between approximately 1 mm and approximately 5 mm.
  • d 3 is advantageously 2 mm.
  • the height of the strips 8 (that is to say their dimension in a direction parallel to the axis of the tubular element 1) is substantially equal to that of the slide 2.
  • Each end of the slide 2 has a lateral recess 17, 18 serving to ensure a locking position of the cup 3, when the latter is, respectively in the fully retracted position, or in the fully extended position.
  • the diameter d 4 of each recess 17, 18 corresponds substantially to the diameter d 1 of the lugs 4.
  • the recess 17 is oriented opposite the recess 18 relative to the slide 2.
  • the tubular element 1 is extended by a cylindrical base 6, itself closed at its lower end, by a transverse bottom 7 which gives good rigidity to the base 6.
  • the height of the base 6 is sufficient to accommodate the cup 3 in the low position when the pins 4 are in the lateral recesses 17.
  • a cylindrical envelope 11 of plastic material, of reduced thickness, is fitted onto the tubular element 1.
  • the envelope 11 is retained axially, in the upper part, by a flange 12 of the cylindrical element 1 which is crossed, during the engagement of the casing 11 on the element 1 by deformation of this element 1.
  • This deformation is allowed, in particular, by the fact that the fact that at least one slide 2 opens out at the top 12a and cuts the edge 12.
  • the base 6 forms with the tubular element a shoulder 16 on which the lower end 15 of the cylindrical envelope 11 comes to bear.
  • the cylindrical envelope 11 is immobilized axially between the shoulder 16 and the rim 12, but it is free to rotate relative to the tubular element 1.
  • the casing 11 has on its internal wall two helical grooves 13 offset by 180 °, in which the free ends of the lugs 4 are engaged.
  • the grooves 13 open at the bottom 11a of the casing 11 to allow, in particular, the engagement of the pins 4.
  • the bands 10 constantly exert an elastic support against the lugs 4, which ensures permanent play take-up and gives a "flexible" character to the movement of rotation, with a braking effect and an anti-vibration effect.
  • the flexible friction is ensured by elastic deformation of the lug 4 in the slide, the diameter d 1 of the lug in the rest position being slightly greater than the width of the corresponding slide.
  • the cup can be produced by bi-injection of two materials: an elastomeric material to form the lug (s) and a rigid or semi-rigid material for the rest of the cup.
  • the elastic deformation of the lug 4 can be ensured by its structure. As can be seen in FIG. 3, the lug 4 is provided with a central recess 4a making it possible to elastically reduce the diameter d 1 of the lug in the corresponding slide.
  • the lug 4 is crossed by a slot 4b making it possible to reduce the width of the lug in a direction perpendicular to the slot 4b.
