Definitions

  • the present invention relates to an assembly for dispensing a fluid product, in the form of liquid or paste, allowing aseptic storage of the product.
  • Numerous distribution assemblies comprising a container, containing the product to be distributed, and a distribution head having a distribution channel communicating, on the one hand, with the container containing the product to be distributed and, on the other hand, with the outside; a device carried by the dispensing head allows the user to distribute the product at will.
  • the present invention relates to a distribution assembly of the above type in which the fixing of the flexible membrane, while being simple, is very reliable.
  • a dispensing assembly of a liquid to pasty product comprising a container containing the product, a dispensing head having a dispensing channel, a flexible membrane having a dome-shaped part which defines in the head dispensing a variable volume compression chamber in communication with the container, an inlet valve being placed in this communication and allowing only the passage of the product from the container to the compression chamber, said compression chamber, the valve inlet and a distribution valve constituting a product distribution pump, said flexible membrane being held on the distribution head by a fixing element consisting of a ring having an opening from which emerges the compression dome of the membrane flexible, is characterized by the fact that the ring carries an annular projection surrounding said opening, the dispensing head being provided with an annular groove receiving an annular groove that has the flexible membrane and which surrounds the compression dome of the flexible membrane, the annular projection of the ring being forced into the annular groove of the flexible membrane.
  • the intake valve is advantageously molded in one piece with the flexible membrane.
  • Distribution assemblies have already been proposed comprising a closure system located at the terminal part, opening to the outside, of the distribution channel, said system consisting of a seat and an elastic blade at least partially in contact with the seat when there is no distribution, deviating at least partially from said seat by bending under the pressure of the product to be distributed and returning by elasticity to its initial position when the distribution ceases; the closure system described above with an elastic blade constituting a distribution valve, when associated with an intake valve, the assembly consisting of the variable-volume compression chamber and these two distribution valves and d The intake constitutes a product distribution pump.
  • the distribution valve consisting of the elastic blade
  • the flexible membrane is molded in one piece with the flexible membrane; consequently, the fixing of the flexible membrane, according to the invention, makes it possible to ensure the tightness of the compression chamber and that of the closing system at rest by carrying out a stressing of the elastic blade on its seat; it allows conservation of the product, during the storage period, in good conditions.
  • the dispensing head is rotatably mounted between at least two positions, a position in which a communication between the compression chamber and the container is closed and a position where said communication is open. This allows better isolation during storage of the product contained in the container.
  • the assembly comprises a rigid bottle on which a support is fixed, the dispensing head being secured axially to said support and free to rotate relative to the latter
  • the support has an internal cylindrical external skirt housed in a sealed manner in the annular space between an internal tubular part and an external tubular part that includes the dispensing head.
  • the wall of the internal cylindrical external skirt of the support is crossed by a skylight
  • the internal and external tubular parts of the dispensing head being provided respectively with a longitudinal slot and a passage located opposite, the passage opening into the compression chamber and being closable by the intake valve, the internal cylindrical internal skirt of the support and the internal tubular part of the dispensing head communicating with the container, the longitudinal slot and the passage being placed opposite of the skylight in the position of the dispensing head relative to the support for which the communication between the compression chamber and the container is open.
  • the container is a flexible pocket housed inside the rigid bottle and secured in a sealed manner to a sleeve extending towards the inside of the bottle the internal cylindrical outer skirt of the support, the bottom of the rigid bottle having an orifice air intake.
  • the container is the rigid bottle and the assembly comprises a dip tube plunging to the vicinity of the lower part of the rigid bottle and being connected, at its upper part, to the internal cylindrical outer skirt of the support.
  • a dispensing assembly according to the invention comprises a rigid bottle 1 having a neck 2 carrying at its outer periphery a snap bead 4.
  • the bottle 1 is adapted to receive a support 10 for a dispensing head 20.
  • the support 10 has concentric cylindrical skirts with circular section extending from a transverse wall 10A, on either side of said wall; said skirts extend relative to this wall 10A either towards the bottle 1, in which case they are said to be interior, or on the side opposite to the bottle 1, in which case they are said to be exterior; thus the support 10 has two external skirts, namely an external skirt 12 and an internal skirt 13, and two inner skirts, namely an outer skirt 15 and an inner skirt 14; the internal internal skirt 14 has at its lower part a snap-on bead cooperating with the snap-on bead 4 of the neck 2 of the bottle 1 to ensure the joining, in the axial direction, of the support to the bottle 1; in addition, anti-rotation fins 5 placed axially between the neck 2 and said internal inner skirt 13 also prevent the support 10 from rotating relative to the bottle 1; this joining of the support 10 and the bottle 1 is carried out in leaktight manner thanks to an annular sealing lip 11 carried by the support 10 and applied against the upper edge of the neck 2 of the bottle 1.
  • the dispensing head 20 has a generally cylindrical shape of revolution with a truncated upper part; more specifically, the dispensing head 20 has a cylindrical outer casing 22, of circular section, the lower part of which is slammed on a snap ring 16 carried by the support 10; thanks to this arrangement, the dispensing head 20 is held axially relative to said support 10 while being able to rotate relative to said support 10.
  • the dispensing head 20 has a flat surface 20A extending in a plane perpendicular to the plane of FIG. 2 and inclined on the axis of the bottle 1; this plane is interrupted at the center of the dispensing head 20 by a recess 50 bordered by a semi-cylindrical wall 20D extending to a transverse bottom 20B and intended, as described below, to constitute a compression chamber 50 .
  • the dispensing head comprises two tubular parts extending towards the support 10, an external tubular part 24 and an internal tubular part 23; the internal cylindrical outer skirt 13 of the support 10 is housed in a sealed manner in the annular space comprised between said internal tubular parts 23 and external 24; similarly, the external tubular part 24 of the dispensing head 20 is housed in a sealed manner in the annular space comprised between the internal external 13 and external 12 skirts of the support 10; this baffle mounting ensures good sealing of the chamber 50 relative to the support 10 despite the mounting in rotation of the dispensing head 20 on said support 10.
  • the container containing the product to be dispensed is a flexible bag 8 housed inside the bottle 1, secured in a sealed manner, for example by heat-sealing, to a sleeve 19 of the support 10, extending from the transverse wall 10A and extending towards the bottle 1 the internal external skirt 13 of the support 10.
  • the dispensing head 20 is mounted so as to rotate relative to the support 10 between at least two positions: a position in which a communication between the chamber 50 and the interior of the flexible bag 8 is closed, and a position where said communication is open; for this purpose, the wall of the internal external skirt 13 of the support 10 is traversed by a dormer 18, and the internal tubular 23 and external 24 parts of the dispensing head 20 are respectively provided with a longitudinal slot 26 and a passage 27 located opposite; the passage 27 opens into the chamber 50 to the right of the bottom 20B.
  • the dispensing head 20 carries at its upper part a flexible membrane 30 covering the flat part 20A of the dispensing head 20; at its highest end, the flexible membrane 30 has a bevel profile defining an elastic blade 31 applied to the end of the flat part 20A into which the terminal part opens, which opens to the outside, of a distribution channel 21 passing through the distribution head 20 and the other end of which opens into the chamber 50; said chamber 50 is bordered externally by a dome 32 which has the membrane 30 in line with the bottom 20B; the flexible membrane 30 has an annular groove 34, surrounding the base of the dome 32, which is received in a corresponding annular groove 25 hollowed out in the flat part 20A of the dispensing head 20; this arrangement makes it possible to perfectly position the membrane 30 relative to the dispensing head 20 and in particular the elastic blade 31; it also allows effective fixing of the membrane 30; for this purpose, in accordance with the invention, a ring 40 having an opening 42 for the passage of the dome 32 has an annular projection 41 force fitted into the annular groove 34 of
  • FIGS. 10 and 11 show examples of profiles of annular grooves 25 and 34 and of annular projection 41 which have given good results;
  • the annular groove 25 with which the dispensing head 20 is provided has a generally rectangular section and receives a part of complementary shape from the flexible membrane 30 defining a groove 34 having a generally also shaped section rectangular;
  • the annular projection 41 of the ring 40 is bordered by slightly conical annular faces 41A, 41B, approaching towards the flat part 20A of the dispensing head 20; the angle of the cone is for example the draft angle usually used in molding techniques.
  • the annular groove 25 has a section in the general shape of a trapezoid, the large base of which is on the side of the bottom of the groove 25;
  • the groove 34 of the flexible membrane 30 has a complementary shape, also trapezoidal, and the annular projection 41 of the ring 40 carries at its free end an annular protuberance 141 which, when the ring 40 is in place, creates a force component transverse coming to clamp the sides of the groove 34 of the membrane 30 against the sides undercut of the groove 25 of the dispensing head 20.
  • a distribution pump is thus constituted in a simple manner, the elastic blade 31 playing the role of distribution valve associated with chamber 50 with variable volume; this simplicity is increased when, as shown in FIG. 2, the valve 33 is molded in one piece with the elastic membrane 30; the annular bearing 41 being provided eccentric with respect to the opening 42, one thus spares the right of the root of the valve 33 a bearing 20C coming to stress the valve 33 in application on its seat 20B, thus improving the efficiency of the distribution .
  • the intake valve can be independent of the membrane 30, as shown in Figure 9 in which said valve is constituted by a ball valve 133 disposed in the passage 27; it can also be noted in this figure the presence of a U-shaped channel 20E hollowed out in the flat surface 20A of the distribution head 20 downstream of the distribution channel 21; the channel 20E allows the product to be guided at the outlet of the distribution channel 21, guidance which is all the more useful when the product distributed is liquid.
  • the bottom of the bottle 1 is pierced with an orifice 3 for air intake facilitating the shrinking of the flexible bag 8 as the product it contains is dispensed; at rest, after use, the product fills the bag 8 and the chamber 50; after having removed the overcap 6 which comprises the assembly and put the dispensing head 20 in the position it occupies in FIG. 2, a pressure exerted on the dome 32 pushes the product through the distribution channel 21, which product lifts the blade 31 and is dispensed; when the action on the dome 32 ceases, the blade 31 returns to its seat; during the return movement of the dome 32 to its rest position, the valve 33 lifts, letting product pass to the chamber 50; the bag 8 follows this transfer of product without constraint due to the entry of air through the orifice 3.
  • the dispensing head 20 is turned relative to the support 10 until close the communication between the chamber 50 and the pocket 8; the overcap 6 is then put in place and the product is stored securely.
  • FIGS 3 to 5 show a variant distribution assembly according to the invention; this variant is of the kind described above, the parts which constitute it and which are identical or play the same role as those of the previous variant bear the same reference; this variant differs from the previous variant in that it is the rigid bottle 1 which constitutes the container containing the product to be dispensed; a dip tube 7 connected to its part greater than the internal external skirt 13 of the support 10 plunges to the vicinity of the bottom of the bottle 1; at the upper part of the bottle, means are provided for venting the upper volume of the bottle 1 located above the product it contains; these venting means consist of an axial groove 17 formed on the inner surface of the outer outer skirt 12 of the support 10 and opening into the bottle 1, and by another axial groove 28 formed on the outer surface of the outer tubular part 24 of the dispensing head 20 and opening to the outside of the bottle 1; the position of the axial grooves 17 and 28 is such that the venting takes place, or not, depending on whether the communication between the chamber 50 and the bottle 1 is open ( Figure 4) or
  • the suction valve 33 takes place in a rebate 29 formed on the surface of the bottom 20B; the rabbet 29 has a shape corresponding to that of the valve 33 and ensures better transverse behavior of said valve 33, which increases the longevity of the latter.
  • the bottle 101 carries a support 110 of a dispensing head 120 rotatably mounted on the support 110 in an inclined plane relative to the axis of the bottle 101 in the position of the head 120, illustrated in the figure 7, for which said communication is closed, the support 110 and the head 120 have concordant cylindrical external contours allowing the fitting of a perfectly cylindrical overcap 106; as seen in Figure 8, in the dispensing position, the axes of the support 110 and the head 120 form an angle between them and it is not possible to cover the entire overcap 106; it should be noted that in this position of distribution, the distribution of the product is facilitated, the user having the bottle 101 in hand.
  • the ring 40 can be produced by superinjection of a rigid material on the flexible membrane 30.
