Definitions

  • the present invention relates to a distribution assembly for one or more fluid product (s) in the form of a liquid or cream (or paste) of varying thickness. This set makes it possible in particular to distribute cosmetic or pharmaceutical products.
  • Numerous dispensing assemblies comprising a container containing the product to be dispensed, on which a dispensing head is fixed, removably or not.
  • This dispensing head comprises a device allowing the user to actuate the dispensing, and at least one dispensing channel communicating, on the one hand, with the container containing the product to be dispensed, and, on the other hand, with the 'outside.
  • the container when there are several products to be distributed, the container may comprise several parts, either that it consists of several independent containers, or that it consists of a single container divided by internal partitions into several compartments, each of the containers or compartments being connected to a channel of the same dispensing head.
  • the dispensing head may also contain a compartment for a product different from that contained in the container, this compartment being connected to the distribution channel for the product contained in the container or to a different channel.
  • the closure system consists of the edge of the sleeve of elastic material which rests on the two opposite faces of the end of said planar partition; this edge is in contact with these two faces of the partition when there is no distribution, deviates from these faces when there is distribution of the product to be distributed and returns by elasticity in contact with these faces when ceases the distribution.
  • the present invention aims to provide for the distribution assemblies, a closure system which is perfectly sealed at rest, that is to say when there is no product distribution, which opens only under the pressure of the product to be dispensed, and which practically does not allow, by itself, air intake.
  • This system is, therefore, aseptic by itself, which is not the case for the patent 4,099,651 cited above.
  • the invention also aims to provide an assembly whose dispensing head ensures, by itself, effective pumping of the product.
  • the present invention therefore relates to a distribution assembly of at least one fluid product, assembly which comprises a container and a distribution head containing at least one distribution channel of the product (s) to be distributed, a system for closure being located at the terminal part, opening on the outside of (or each) distribution channel, said system being formed by at least one obturator which is part of a piece of elastically deformable material of the distribution head and by at least one seat, which is part of another part of the dispensing head, the shutter (s) being in contact with their associated seat when there is no dispensing, s '' spreading from said seat by elastic deformation under the pressure of the product to be dispensed and returning by elasticity in contact with said seat when dispensing ceases, characterized in that the dispensing head contains a second associated valve to the closing system.
  • the (or each) shutter (s) is subjected to the action of a constraint member tending to keep it (or them) applied (s) to the seat with which it (s) cooperates (s) to seal the closing contact.
  • the tightness mentioned in the definition below is only ensured with production imperfections. According to the invention, it must be sufficient to prevent practically any aspiration of air through the closure system after the end of the dispensing of the product, whatever the viscosity of the product to be dispensed. Since the tightness is somewhat a function of the contact zone between the shutter and the seat, the invention provides for choosing a zone of contact of sufficient size for sealing to be ensured.
  • the closure system therefore forms a valve or a valve which can only open in one direction: the direction of distribution of the product.
  • the closure system according to the invention which, in practice, consists only of a small contact area between a shutter of flexible material and a seat, has the advantage of being able to adapt to all of the dispensing heads. , whether they are mounted on welded tubes, distributors with follower piston or flexible bag or on rigid bottles. It can also easily be integrated with dispensing heads having very variable aesthetic shapes. Indeed, the flexible part comprising the shutter and the part carrying the seat of the shutter can have various shapes.
  • the push button may advantageously include a flexible membrane accessible from the outside which acts as a piston by modifying the volume of the internal space.
  • the volume of the pump body formed can be arranged parallel to or perpendicular to the longitudinal axis of the assembly, the push-button being actuated parallel or perpendicular to said longitudinal axis.
  • part of the wall of the dispensing head is made of thin elastic material, so that it can be pierced using a hypodermic needle; said needle is used either to create a vacuum and, consequently, to eliminate the air and suck the product contained in the container in the dispensing head, without contaminating the dispensing orifice, or to create an overpressure which makes it possible to purge the dispensing head using a sterile gas, for example nitrogen.
  • the thinned part can constitute a portion of the blade fitted with a closure system lip.
  • FIG. 1 schematically represents a dispensing assembly 2101 in which the product to be dispensed is contained in a flexible bag 2102 protected by a rigid enclosure 2110 provided with an air intake opening 2110 a .
  • the dispensing head 2103 is of the type with lateral outlet fitted with a nozzle 2103 a and which acts as a pump.
  • Said head 2103 comprises a piece 2104 comprising the seat on which is fixed the flexible pocket 2102 and which is fixed on the edge of the rigid enclosure 2110.
  • a blade 2105 is placed on the piece 2104 comprising the seat and is held by a cover 2106.
  • the part 2104 comprising the seat is constituted by a plate 2141 perpendicular to the longitudinal axis of the assembly 2101 generally having the form of a disc provided with a spout.
  • the piece 2104 comprises a bead 2104 a having an oblique flat surface 2104 d forming a seat facing the axis of the assembly and towards the container. It has a cylindrical skirt facing the cover 2142 which surrounds the blade except at the end of the spout 2103 a and a skirt 2143 facing downwards, onto which the flexible tube is welded.
  • the part is pierced in the vicinity of its axis with a circular opening 2144 on which is fixed a non-return valve with bell constituted by a valve 2113 illustrated in more detail in FIG. 2.
  • This bell valve consists of two capsules 2114 and 2115, the lower capsule 2114 being made of relatively rigid plastic and the capsule 2115 being relatively flexible so as to be able to deform.
  • the two capsules are fixed to each other by fitting.
  • the two capsules 2114 and 2115 are each provided with a skirt 2116 and 2117 turned towards each other by forming a tight seal and capable of sliding against each other until separating leaving a space between them during the deformation of the capsule 2115.
  • the capsules 2114 and 2115 have openings 2118 and 2119 respectively which can only be brought into communication when the skirts 2116 and 2117 are separated.
  • the blade 2105 has, in the beak 2103 , a bevelled part 2105 a which presses tightly on the surface 2104 d forming a seat and a thinned part in the form of a dome 2111, the dome having at its base a diameter greater than that of the bell valve 2113. Between the dome 2111 and the closing system F, the blade 2105 is hollowed out with a channel 2105 b .
  • the cover 2106 covers the blade except in its part corresponding to the closing system F and it is provided in its center with a circular opening 2161 through which the dome 2111 projects outside.
  • the device of Figure 1 operates as described below.
  • the user wishes to dispense the product contained in the flexible tube 2102, he presses on the elastic dome 2111 which reduces the internal space E contained under said dome 2111, the valve 2113 being closed.
  • the product contained in the space E and in the channel 2105 b undergoes an overpressure and opens the closing system F.
  • the closing system F closes again and the dome resumes its forms by elasticity which causes the formation of a depression in the internal space E.
  • the valve 2113 opens and product is transferred from the flexible tube 2102 in the space E.
  • FIG. 3 schematically represents a distribution assembly 2501, the distribution head 2503 of which forms a pump because it comprises two valves.
  • the distribution assembly 2501 comprises a flexible pocket 2502 protected by a rigid enclosure 2510 provided with an air intake opening 2510 a .
  • the dispensing head comprises, firstly, a piece 2504 comprising the seat, secondly, an O-ring piece 2505 molded in one piece with a flexible blade forming a dome 2507 and carrying a lug 2508 forming part of a second valve 2513, and, thirdly, a cover 2506.
  • the part 2504 comprising the seat has the general shape of a disc fixed on the upper edge of the rigid enclosure 2510 and it is provided with a cylindrical inner skirt 2541 on which the flexible pocket 2502 is welded. On a portion of its periphery, it is hollowed out of a groove 2542 having in section the shape of a segment of circle into which opens a radial channel 2543 hollowed out in the part 2504.
  • the part 2504 is hollowed out by a channel 2544 parallel to the longitudinal axis of the assembly 2501 which opens into the flexible pocket 2502 at one end and is in communication with a notch 2545 of the part 2504, separated from the channel 2544 by a wall 2546 parallel to the axis of the assembly 2501 whose upper edge is beveled.
  • the O-ring 2505 has, in section, the shape of a circle provided with a lug 2552 at the level of the closure and it fits into the groove 2542.
  • the dome 2507 is located above the support 2504 and it defines above said support 2504, an internal space E which communicates, on the one hand, with the channel 2543 and, on the other hand, with the notch 2545.
  • the base of the dome 2507 is extended on the side opposite to the opening of the channel 2543 by a plate carrying a lug 2508 which cooperates with the wall 2546 to form a valve 2513. In this valve 2513, the lug 2508 rests tightly on the surface of the rim of the wall 2546.
  • the cover 2506 is fixed to the periphery of the support 2504 and it is provided with an opening 2561 through which the dome 2507 projects.
  • the cover 2506 is hollowed out by a groove 2562 having the shape in section, of a circle segment which adjusts to the groove 2542 to form together (in section) a larger circle segment.
  • the groove 2562 and a fraction of the groove 2542 are dug by a product supply channel 2509.
  • the assembly 2501 operates as follows.
  • the user wishes to distribute the product, he presses on the elastic dome 2507 and reduces the internal space E, the valve 2513 being closed.
  • the product contained in this space undergoes an overpressure and exerts a thrust via the channel 2543 on the torus 2505. It causes the displacement of the latter by elasticity in the direction of the arrow f 2 , which opens the channel of brought 2509 on the outside.
  • the product is distributed.
  • the pressure of the product to be distributed on the torus 2505 ceases and the latter resumes its place by elasticity and closes the channel 2509.
  • the dome regaining its shape by elasticity, it occurs a depression in space E.
  • This depression causes the valve 2513 to open, the lug 2508 moving apart by bending the rim from the partition 2546.
  • Product contained in the bag 2502 is sucked into space E through the conduit 2544 and the notch 2545.
  • the dispensing head is ready for a new distribution of the product.
