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 the distribution ceases.
  • the object of the present invention is 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 subject of the present invention is therefore a distribution assembly for at least one fluid product, assembly which comprises a container and a distribution head containing at least one distribution channel for the product (s) to be distributed, a distribution system 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 the dispensing ceases, characterized in that the (or each of) the shutter (s) is subjected to the action of '' a constraint member tending to keep it (or them) applied (s) on the seat with which it (s) cooperates (s) to ensure the tightness of the closing contact.
  • 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 made of flexible material and a seat, has the advantage of being able to adapt to all of the dispensing heads, which '' 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 obturator can be constituted either by a lip moving away from the seat by bending perpendicularly to the direction of thrust of the product, or by an elastic element, a part of which is disposed opposite the outlet opening of the channel. distribution and which, in this area, departs from the seat by elasticity parallel to the direction of thrust of the product.
  • the shutter can be of any material that can deform elastically. It is preferably made of natural, synthetic or thermoplastic elastomer. Among the elastomers which can be used, there may be mentioned, for example, styrene-butadiene copolymers, nitrile rubbers, polychloroprene or neoprene, EPDM rubber, polyurethanes, silicone rubber and ethylene-vinyl acetate copolymers.
  • the shutter can when the obturator is a lip, be constituted by an aluminum sheet fixed on a sheet of plastic material: polyethylene or polyethylene terephthalate (PET) or sandwiched between two sheets of plastic.
  • the seat is preferably made of a rigid material, but can also be, in particular when the shutter has the shape of a lip, of elastic material.
  • the constraint member has the function of maintaining the shutter applied to the seat during storage and of increasing the pressure necessary to obtain the deformation of the shutter. This improves the tightness of the closure system. It can also have the function of facilitating the return of the shutter to its closed position. It is advantageously adjustable so as to make it possible to adjust the pressure of the product to be dispensed necessary for the opening of the closure system. In the absence of a constraining member, it is often difficult to maintain the seal of the closure during storage before and after the first use of the product to be dispensed.
  • the constraint member can be constituted by a rigid element pressing on the piece of flexible material so as to keep the lip applied on the seat.
  • This rigid element may be a cover or a support holding the piece of flexible material up to the vicinity of the lip, a partition perpendicular to the direction of flow pressing on a wall, which is parallel to it, of the elastic piece; this wall can be obtained, for example, using an extra thickness of the piece of flexible material.
  • the constraint member may also not be rigid but be made of elastic material: it is, for example, constituted by a bead or an elastic lug limiting the movement of the flexible lip.
  • the constraint member is, more particularly, constituted by a lug or bead of elastic material holding the flexible piece on the rigid element comprising the seat, so as to oppose the deformation of the shutter.
  • the end part of the distribution channel is preferably delimited on the one hand, by a part partially made of flexible material comprising the shutter and on the other hand, by a part comprising the seat of the shutter.
  • the channel can be formed in the room comprising the shutter and / or in the room comprising the seat.
  • the passage of the product from the channel to the closure system is by a slope, so as to facilitate the flow of the product, avoiding a threshold effect. This slope is advantageously located in the seat.
  • the channel can also be delimited by an area where the part comprising the shutter and the part comprising the seat are assembled in a sealed manner, for example by gluing or using a weld bead.
  • the shutter is constituted by a lip which departs from the seat by bending, perpendicular to the direction of thrust of the product to be dispensed.
  • the contact area between the flexible lip and the seat can be curved or wavy; it is preferably made up of a plane portion; said plane portion can be, for example, rectangular or have a shape of a rounded tongue at its end.

  • 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 edge of the partition 2546.
  • Product contained in the bag 2502 is sucked into space E by the conduit 2544 and the notch 2545.
  • the dispensing head is ready for a new distribution of the product.
