Definitions

  • the present invention relates to a product distribution assembly in which the product to be distributed is contained in a flexible bag.
  • Such assemblies are used more particularly in the case where the dispensing head, associated with the flexible bag, constitutes a pump without air intake or in the case of aerosol dispensers in which the product is introduced into a flexible bag and the propellant is introduced into the container around the pocket.
  • the flexible pockets are most often formed of a bag comprising two walls of variable shape, for example rectangular, the walls being welded on at least one side.
  • the flexible bag is tightly fixed, most often by welding, on a dispensing head.
  • the flexible bag gradually empties and, therefore, its walls approach each other. It is then common for the two walls to touch before all of the product is distributed and to seal one another over one or more zones, said zones possibly constituting a tight barrier. Part of the product to be distributed may thus be trapped, its distribution having become impossible. The losses due to the product thus trapped can be very significant.
  • a grid is introduced into the flexible pocket according to the present invention, parallel to the axis of the skirt and which, whatever the shape of the flexible pocket, remains parallel to this axis.
  • the present invention therefore relates to a product distribution assembly in which the product to be distributed is contained in a flexible pocket fixed on the skirt of a cover on which is mounted a distribution head comprising a tube for the outlet of the product of the pocket, said flexible pocket containing an internal part, the internal part being a semi-rigid part, the part defining with the walls of the pocket flow channels for the product distributed towards the cover and therefore towards the product outlet pipe, the internal part being fixed to the skirt by a fixing device characterized in that the mean plane of the internal part is practically parallel to the axis of the skirt, the relative dimensions of the pocket and the part being such that said part remains in its position and cannot be put in a position where its mean plane is perpendicular to the axis of the skirt.
  • the device for fixing the part is preferably movable in flexion and / or in rotation relative to the outlet pipe of the product.
  • the part can better resist deformations of the pocket.
  • the semi-rigid part only covers part of this median plane.
  • This arrangement facilitates the introduction of the part into said flexible pocket.
  • the part is preferably shorter than the pocket.
  • the bag can be shortened and come to be pressed under the dispensing head, which allows the bag to be completely emptied.
  • the fixing device advantageously comprises a hollow ball joint; the ball then allows both the passage of the product and a rotational movement of the part.
  • the semi-rigid part can be directly molded with the product outlet tubing or with the fixing device
  • the semi-rigid part is a grid. Its longitudinal and transverse elements are preferably rectilinear and perpendicular, the longitudinal elements preferably being parallel to the longitudinal axis of the pocket.
  • the longitudinal and transverse elements of the grid are advantageously arranged in two parallel planes, that is to say that they intersect and are welded to each other without any interpenetration.
  • the longitudinal and transverse elements may also have undulations in planes perpendicular to the median plane of the grid.
  • the transverse and longitudinal elements can also be somehow woven.
  • a bead intended to prevent the ends of the longitudinal and transverse elements of the grid from risking piercing the wall of the pocket.
  • the mesh size of the grid is small enough that the walls of the pocket cannot stick to the inside of the mesh.
  • the largest possible dimension is therefore a function of the stiffness of the pocket walls and the viscosity of the product dispensed. This dimension is generally between 1.5 and 20 mm, for example of the order of 9 mm.
  • the part consists of semi-rigid bands separated by slits and connected to each other at their ends, the bands being curved either on one side or on the other of the median plane of the part, two neighboring bands being curved in opposite directions.
  • the curved strips keep the walls of the bag apart.
  • the walls of the pocket press with increasing force on the curved strips.
  • the latter which have a certain flexibility, deform in the direction of the median plane of the part. The distribution of the product remaining in the pocket is thus facilitated.
  • a device forming a capillary network is fixed in the vicinity of the orifice of the outlet tube between the part and said tube, perpendicular to said grid.
  • This device has, in particular, an annular shape. It can be full and have channels or ribs on the product side. It can also be constituted by a grid.
  • This device completes the action of the grid.
  • FIGS 1 and 2 show a flexible bag 102 of a dispensing assembly according to the invention.
  • the flexible bag 102 is fixed on a dispensing head; the dispensing head is mounted on a cover 105 of which only the inner skirt 151, on which the pocket is fixed by welding, is shown.
  • This inner skirt consists of a cylindrical part 151 a on which a fixing device 108 is disposed.
  • This consists of two symmetrical brackets in the form of a square 108 a and 108 b , the part 181 a or 181 b fixed to the skirt 151 being perpendicular to the longitudinal axis of the flexible bag and the part 182 a or 182 b parallel to the axis being directed towards the bottom of the bag 102.
  • the free end of these parts 182 a and 182 b carries a bead 183, the beads 183 a and 183 b facing each other.
  • the grid 106 is held between the legs 108 a and 108 b , more particularly between the beads 183 a and 183 b .
  • FIG. 3 represents a distribution assembly 201 during assembly.
  • the assembly 201 comprises a flexible pocket 202 and a dispensing head 204 mounted on a cover 205.
  • the said cover comprises a cylindrical skirt 251 on which the pocket 202 is fixed by welding.
  • the pocket 202 contains a grid 206 and a device forming a capillary network 209.
  • the grid is fixed to the device 209 by a fixing device 208 consisting of a hollow ball joint 281 associated with a spherical cap 282 provided with slots arranged in the center of the device forming a capillary network 209.
  • the ball 281 consists of two shells 281 a and b fixed on an annular ring 281 c .
  • Said crown 281 c carries two tabs 281 d between which the grid 206 is fixed.
  • the hollow ball 281 is mounted by snap in the spherical cap 282. When the grid is mounted the product can pass through the ball 281 and the cap 282 in the direction of the dispensing head.
  • the device 209 forming a capillary network is, according to the embodiment shown in FIG. 3, fixed to the rim of the cylindrical skirt 251. It consists of a grid comprising radial elements 291 and an annular element 292. This device 209 completes the action of the grid 206 by preventing the walls of the flexible bag 202 from being sucked inside the cover 205 and blocking the opening for the outlet of the product from the container in the head 204.
  • the ball joint 281 is slammed into the cap 282.
  • the flexible bag 202 is filled with the product and the edge 221 of the flexible bag is welded.
  • the cover 205 is then fixed by fitting onto the edge of a rigid enclosure (not shown) protecting the flexible bag.
  • Figures 4 and 5 show a semi-rigid part 306 according to the second embodiment.
  • the part 306 has in projection on its median plane a rectangular shape. It consists of three curved strips 361a, 361b, 361c separated by slots 362a and 362b.
  • the strips 361a, 361b, 361c are connected at one of their ends to a strip flat transverse 363 and at their other end to another flat transverse strip 364 carrying two lugs 365 for fixing to a device for fixing to the outlet pipe of the dispensed product (not shown).
  • the bands 361a and 361c are curved so as to project from one side of the median plane M and the middle band 361b is curved so as to systematically project from the other side of the median plane M.
  • the part shown in Figures 4 and 5 has three bands. Note that the number of bands may be higher.
