Definitions

  • the present invention relates to a fluid product dispenser comprising a fluid product reservoir and a dispensing member through which the fluid product is discharged.
  • the dispensing member comprises a body and an actuating rod that can move axially back and forth relative to the body over a maximum rod stroke.
  • the dispenser also comprises a dispensing orifice at which a user can recover the dispensed fluid product, on the other hand, the dispenser comprises a rotary actuation member that the user can rotate on himself, and a transmission engaged both with the body or the actuating rod of the dispensing member and the rotary actuating member.
  • Cam means are formed by the rotary actuator member and the transmission member to convert rotation of the rotary actuator member into axial movement of the actuator rod or body.
  • This type of dispenser can be called a "rotary actuated dispenser". It finds a privileged application in the fields of cosmetics or even pharmacy, without excluding food and household products.
  • the document US 2017/157377 and the document EP2859958 which each describe a rotary actuated distributor comprising a rotary actuating member forming a cam track.
  • the distributor of the document EP2859958 includes a pump actuation rod forming two opposed rods which follow the cam path.
  • the actuating rod is connected to a ball applicator via a telescopic sliding connection.
  • the object of the present invention is to remedy this drawback of the prior art by defining a dispenser with rotary actuation which reliably and reproducibly delivers the entire dose of fluid product.
  • the dispenser of the invention according to claim 1 ensures that the actuating rod has been fully depressed.
  • the cam means comprise at least one cam track of variable axial height and at least one cam follower which follows the respective cam track.
  • the cam path can be secured to the transmission member or to the rotary actuation member.
  • the transmission member can act on the actuating rod or on the body.
  • the transmission device acts on the bottom of the reservoir on which the dispensing member is mounted.
  • the actuating rod can be moved relative to a fixed body or, on the contrary, the rod can be static and it is then the body and the reservoir which are moved relative to the fixed rod.
  • the transmission member comprises a central sleeve engaged with the actuating rod and a cam crown defining at least one cam path of variable axial height.
  • the elastic means can then be formed by the transmission member.
  • the cam crown can be connected to the central sleeve by several flexible bridges forming the elastic means and/or the cam crown is elastically deformable, forming the elastic means.
  • the rotary actuating member can then comprise several profiles forming cam followers which engage with and follow the cam tracks of the cam crown.
  • the rotary actuation member can comprise a rotary actuation ring that a user can grasp and a recovery cup in which the user can recover the dispensed fluid product.
  • the rotary actuator ring has no axial displacement and the recovery cup is elastically deformable to follow the axial displacement of the actuator rod.
  • the recovery cup is fixed to the central sleeve of the transmission member, which advantageously forms a connecting sleeve, connected to the actuating rod and an end piece connected to the recovery cup.
  • the elastic means can be formed by the rotary actuating member.
  • the cam crown of the transmission member could be secured to the rotary actuating member by means of flexible bridges.
  • the profiles of the rotary actuating member which follow the cam track of the cam ring could be displaceable or elastically deformable.
  • the profiles could be formed by tabs or flexible blades.
  • the spirit of the invention resides in the fact of providing an excess cam travel which is "attenuated, compensated or authorized" by an elastic deformation of at least one of the parts which intervene in the displacement transformation system (rotary in translation) per cam.
  • This elastic deformation can take place at the level of the rotary actuating member and/or of the transmission member.
  • the embodiments can be declined in numerous versions which are included in the scope of the claims and which are within the reach of a person skilled in the art. All deformations inducing axial elastic bending are possible.
  • the flexible recovery cup that connects the rotary ring to the actuating rod is an attractive feature, which can be implemented independently of excess cam travel and associated spring means.
  • this dispenser comprises several constituent elements, namely a container body 11 which defines a shoulder 111 and a neck 112, a follower piston 12, a container bottom 13, a covering hoop 6, a dispensing member 2, which here is a pump, a receiving ring 3, a rotary actuation member 4 and a transmission 5.
  • the covering hoop 6, as well as the container bottom 13 are optional elements.
  • the transmission member 5 in a very enlarged manner in order to detect the details. It comprises a central sleeve 51 which defines a cylindrical part 511 surmounted by an upper wall 512 in the shape of a dome. At its center, this wall 512 forms an outer end piece 52 whose function will be given below. Internally, as can be seen in the figure 2b , the upper wall 512 forms a connecting sleeve 53 which is axially aligned with the endpiece 52. The function of this connecting sleeve 53 will be given below. A conduit extends through the outer end piece 52 and the connecting sleeve 53.
  • the transmission member 5 also comprises a cam crown 54 which is arranged concentrically around the central sleeve 51.
  • the cam crown 54 is connected to the cylindrical part 511 of the central sleeve 51 by several flexible or flexible lugs 56 , here four in number. Therefore, the cam ring 54 is capable of moving axially with respect to the central sleeve 51 over a limited axial height, for example of the order of a few tenths of a millimeter to two millimeters.
  • the cam crown 54 defines several cam tracks 55, here four in number. Each cam track 55 includes two oppositely inclined ramps 55b, so that they meet at a high point 55c.
  • the inclined ramps of one cam track are connected to the inclined ramps of the adjacent cam tracks at the low point level 55a, where the flexible bridges 56 are advantageously formed.
  • the cam crown 54 defines four cam tracks 55 together defining eight inclined ramps 55b, four high points 55c and four low points 55a.
  • the difference in axial height between the low points 55a and the high points 55b defines an axial cam stroke, which according to the invention is slightly greater than the maximum stem travel of the distribution device 2.
  • each cam track 55 is elastically deformable along its length, creating thus elastic means which would complement the flexible bridges 56 or as a replacement.
  • the dispensing member 2 can be a pump or a valve. In both cases, the dispenser member 2 comprises a body 21 and a valve stem 22 which can be moved axially over a maximum stem stroke. In concrete terms, this maximum rod travel corresponds to the distance traveled by the actuating rod 22 between its rest position and its fully depressed position inside the body 21. This is entirely conventional for a valve or a pump.
  • the follower piston 12 is engaged inside the container body 11 and the bottom 13 is attached to the lower end of the body 11.
  • a fluid reservoir 1 is thus created, which here is of variable volume due to the displacement of the follower piston 12 in the direction of the dispensing member 2.
  • the dispensing member 2 is mounted by means of its fixing ring 3 on the neck of the container body 1.
  • the trim band 6 is snapped onto the container body 1.
  • the transmission member 5 is mounted on the dispensing member 2 by engagement of its connecting sleeve 53 around the free end of the actuating rod 22.
  • the rotary actuating member 4 is mounted on the transmission member 5 via the inside of the covering hoop 6.
  • the rotary actuating member 4 comprises a rotary actuating ring 41 that a user can grasp and a cup of recovery 44 in which the user can recover the fluid product dis tributary.
  • the lower end of the ring 41 is snapped at 42 onto a snap-fastening profile 62 formed inside the cover hoop 6.
  • the rotating actuation ring 41 forms several downward facing shoulders which act as cam followers 43.
  • cam followers 43 are located axially just above the cam ring 54. There are as many followers cam 43 that there are cam tracks 55.
  • the recovery cup 44 is arranged at the upper end of the rotary ring 41 and is made of a flexible material, such as an elastomer.
  • the rotary ring 41 and the recovery cup 44 can for example be produced by overmolding or bi-injection of different plastic materials.
  • the recovery cup 44 defines on its underside a sealed connection sleeve 45 which is in sealed engagement around the end piece 52 of the transmission member 5.
  • An outlet channel is thus defined which connects the actuating rod 22 to a dispensing orifice 46 defined at the level of the recovery cup 44.
  • the distributor On the picture 3a , the distributor is at rest with the cam followers 43 arranged at the level of the low points 55a of the cam tracks 55.
  • the recovery cup 44 is at rest, with a substantially planar shape.
  • the cam followers 43 When a user grasps this distributor, he rotates his rotary actuating ring 41, in one direction or the other: the cam followers 43 will come into engagement with the inclined ramps 55b, which has the effect of moving the transmission member 5 axially downwards, since the rotary actuator member 4 is blocked axially.
  • the cam followers 43 will thus move along the inclined ramps 55b to near the high points 55c. Shortly before reaching these peaks 55c, the actuating rod 22 is normally fully depressed, thus ensuring that the entire dose of fluid product has been dispensed.
  • elastic means are provided which act axially to compensate and thus allow this excess cam travel, thus guaranteeing that the maximum rod stroke has been fully performed.
  • These elastic means are here implemented in the form of the flexible bridges 56 and/or the deformation capacity of each cam track 55.
  • the distributor is seen in the actuated position, that is to say with the actuating rod 22 fully depressed and the cam followers 43 located at the level of the vertices 55c.
  • the deformation of the flexible bridges 56 and/or of each cam path 55 is not represented, because it is difficult to represent.
  • this first embodiment is not limiting at all. Indeed, there are many different variants and versions that achieve the same result, namely to elastically compensate for excessive cam travel relative to the maximum rod travel.
  • an actuating member 4' which is similar to that of the first embodiment.
  • the cam followers 43' here are formed by thin radial tabs which have sufficient elasticity to compensate for or overcome the excessive cam travel.
  • the elastic means are formed by the rotary actuation member, and not by the transmission member 5, as in the first embodiment.
  • This transmission member 5" may comprise an annular sawtooth profile 55" which engages corresponding teeth 43" of a crown 42" whose outer periphery engages in grooves 44" formed by a 4" rotary actuation. Crown 42" is urged against transmission member 5" by a spring 45".
  • the 55" tooth height defines a cam travel that is greater than the maximum rod travel of the actuator rod 22.
  • the crown 42 is driven in rotation so as to move the lugs 43" along the teeth 55". This has the effect of pushing the actuating rod 22 in the distribution body 2 until the maximum rod travel is reached.
  • the excess cam travel formed by the teeth 55" will be collected or taken up by the spring 45" which allows the ring gear 42' to perform a slight downward axial movement, allowing the 43" tines to pass over the tops of the 55" tines.
  • the elastic means have a resistance to deformation which is greater than the force necessary to depress the actuating rod. Therefore, the actuating rod is first moved and fully depressed, then only the elastic means (flexible bridges 56, cam path 55, flexible lugs 43', spring 45") are stressed.
