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 fixed in a sealed manner, 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.
  • the present invention therefore relates to a product dispensing assembly in which the product to be dispensed is contained in a flexible bag fixed on a dispensing head and comprising a tube for removing the product from the bag, the flexible bag containing an internal part, characterized in that the internal part is a semi-rigid part, the mean plane of which is practically parallel to the outlet axis of the dispensed product, and that the relative dimensions of the bag and the part are such that said part remains in its position and cannot be placed in a position where its mean plane is perpendicular to the outlet axis of the dispensed product, and the part defines flow channels of the dispensed product, towards the outlet pipe of the product .
  • the piece thus arranged makes it possible to keep the walls of the flexible pouch apart, so as to prevent them from sticking to one another and to form a tight barrier preventing the flow of a part of the product to be distributed towards the product outlet tubing.
  • the part is semi-rigid so that it cannot twist, or bend, for example to spiral. Indeed, the flow of the product to be distributed would be disturbed.
  • the semi-rigid part can cover a more or less large surface of the median plane of the flexible bag, insofar as its dimensions do not allow it to be placed in a position perpendicular to the axis of exit of the dispensed product.
  • the semi-rigid part covers only part of this median plane.
  • This arrangement facilitates the introduction of the part into said flexible pocket.
  • the part when the part is free, it can move slightly in the flexible pouch, which makes it possible to mix the product, possibly to break its thixotropy and to avoid the formation of preferential channels.
  • 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 part can be free in the flexible pocket. It is preferably fixed to the product outlet tubing. This always gives a junction between the part and the product outlet orifice and thus prevents any risk of formation between the part and the outlet orifice, of a tight barrier by bonding the walls of the bag.
  • the device for fixing the part is preferably movable in flexion and / or in rotation relative to the outlet pipe of the product. Thus the part can better resist deformations of the pocket.
  • 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 rigidity of the walls of the bag and the viscosity of the product dispensed. This dimension is generally between 1.5 and 20 mm2, for example of the order of 9 mm2.
  • the part is made up of semi-rigid bands separated by slots 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 pipe between the part and said pipe, 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.
  • the distribution assembly according to the invention shown in FIGS. 1 and 2 is designated as a whole by 1. It comprises a flexible pocket 2 contained in a rigid enclosure 3 and a distribution head 4 mounted on a cover 5, the pocket flexible containing as a semi-rigid part a free grid 6.
  • the rigid enclosure 3 has, for example, a cylindrical shape and has a side wall 31 and a bottom 32. In this bottom 32 is formed an air inlet opening 33.
  • the cover 5 carries on its face facing the rigid container 3 a cylindrical skirt 51 on the outer wall of which the flexible bag 2 is welded, in particular by rotary ultrasonic welding.
  • This pocket 2 is constituted by a tube of flexible plastic material closed at its lower part by a weld 21.
  • the cover 5 comprises a neck on which is fixed by screwing or snapping the dispensing head 4 forming a pump, comprising two valves and without recovery of air.
  • the flexible pocket 2 contains a grid 6 with bi-oriented mesh made of flexible plastic.
  • This grid 6 for example with square meshes, is made up as visible in FIG. 2 of longitudinal elements 61 and of transverse elements 62 situated in two parallel planes, that is to say that they cross and are welded to each other without interpenetration.
  • the longitudinal 61 and transverse 62 elements have regular undulations 63 as shown in FIG. 2.
  • This grid has dimensions smaller than those of the sachet, which allows it to move within the product and to mix said product, but its length being significantly greater than the width of the flexible pouch, it can not move significantly.
  • the grid 6 remains in its position and cannot be put in another position where its mean plane is perpendicular to the longitudinal axis of the pocket.
  • the longitudinal elements 61 are oriented substantially in the direction of flow of the product towards the head 4, that is to say vertically according to the representation in FIG. 1. These elements 61 determine channels 7 directed in the general direction of product flow. The channels 7 are continuous and free of obstacles since all the transverse elements 62 pass above or below the elements 61.
  • the assembly 1 operates in the manner described below.
  • the user wishes to dispense the product contained in the flexible bag 2, he presses on the dispensing head 4 so as to remove the product.
  • the flexible bag 2 empties and the side walls come closer.
  • the side walls are kept spaced apart by the grid 6, and the formed channels 7 allow the product to be used up.
  • FIGs 3 and 4 show the flexible bag 102 of a dispensing assembly according to the invention.
  • the flexible bag 102 is fixed to a dispensing head similar to that shown in FIG. 1, 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 is disposed the fixing device 108.
  • 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 pocket 102.
  • the free end of these parts 182 a and 182 b carries a bead 183, the beads 183 a and 183 b being made opposite.
  • the grid 106 is held between the legs 108 a and 108 b , more particularly between the beads 183 a and 183 b .
  • FIG. 5 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 281 associated with a spherical cap 282 provided with slots arranged in the center of the device forming 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. 5, fixed to the rim of the cylindrical skirt 251. It is constituted by 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 product outlet 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 6 and 7 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 planar transverse strip 363 and at their other end to another planar transverse strip 364 carrying two tabs 365 for fixing to a device for fixing to the product outlet pipe. distributed (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 6 and 7 has three bands. Note that the number of bands may be higher.
