Definitions

  • the present invention relates to a new device for packaging and dispensing fluid products, and more particularly to a device for packaging and dispensing fluid, liquid or pasty products, of the type comprising at least two flexible bags placed in the same rigid container, and associated with at least two pumps, ensuring, in good conditions of efficiency, the separate storage of at least two fluid products protected from the air and their distribution, separately.
  • the patent application FR-A-28 33,577 in the name of the applicant, describes a device of the pocket-bottle type comprising two pockets placed in parallel in the same bottle, associated with two extraction pumps and one or two pushers to operate the pumps.
  • this device comprises two independent pushers each acting on a pump, so that the user can choose to operate only one of the two pushers to dispense the fluid of his choice.
  • the two pushers being placed next to each other, the user can confuse them and operate by mistake one instead of the other, or inadvertently cause the movement of the second push button by operating the first if his finger is not properly placed on it.
  • Fluid conditioning and dispensing devices of this type are well known. They generally comprise a rigid shell container in which is placed a flexible bag which retracts as the product is extracted.
  • the expulsion of the product out of the bag can be obtained by means of a pump without air intake, or "airless", or under the pressure of a propellant gas acting on the wall of the bag, in the bottle.
  • a vent is provided, generally in the bottom or in the neck of the bottle, to allow the outside air to penetrate in the space between the bottle and the bag each time the pump is actuated and thus allow the bag to retract while maintaining sufficient pressure on its walls.
  • An embodiment according to this technique is described in the patent FR 2.723.356 relating to a device comprising a flexible plastic bag, such as polyethylene or polypropylene, in a rigid container whose neck has an air inlet.
  • the present invention specifically relates to a device for packaging and dispensing fluid products, liquid or pasty, of the type comprising at least two flexible flexible bags placed in the same single rigid container, associated with at least two pumps, ensuring effective distribution of both products, separately.
  • the invention also relates to a device for packaging and dispensing a plurality of fluid products each contained in a separate bag, providing a very good ease of filling bags without the need to resort to complex or specially adapted tools.
  • the subject of the invention is also a device for packaging and dispensing a plurality of fluid products, of the type comprising at least two flexible flexible bags placed in the same single rigid container, ensuring perfect packaging of the product by means of an excellent sealing of the pockets and pumps.
  • the invention finally relates to a device of the type indicated above, which can be manufactured in good conditions of profitability.
  • the device for packaging and dispensing fluid products according to the present invention is of the type comprising at least two flexible flexible bags placed in the same single rigid container, associated with at least one pump, and it is distinguished in that the rigid container is constituted by an open cylinder and the pockets are each provided with a pump and a pusher, and are mounted in opposition on each opening of the cylinder.
  • the bags are fixed by their neck on the openings of the rigid container, each pocket is fixed on each of the two opposite openings of the rigid cylindrical container and, preferably, the bags are fixed to the container via of a ring. It may be advantageous to provide that the ring is incorporated in the neck of the pocket.
  • the cylinder forming the rigid container is in one piece, and a pocket is attached to each of its openings.
  • the cylinder consists of two cylindrical elements assembled end to end.
  • the open cylinder constituting the rigid container may be made in one part, or in two parts, for example two cylinders assembled by their base, by gluing, latching, screwing, welding or any other fastening means appropriate.
  • the cylinder constituting the rigid container may have any cross section, for example circular or polygonal.
  • the pockets can have any shape, adapted to that of the rigid container.
  • the pockets, and the rigid container which contains them have a cylindrical shape on a polygonal, elliptical or circular base.
  • Such a cylindrical shape can be easily made, as indicated below, by blowing or injection-blowing the bag, and by this technique the shape of the bag can be adapted to that of the rigid container, which has the consequence that the Volume losses are reduced to a minimum.
  • the pumps used in the invention are pumps without air intake, type "airless”, as commonly used in the art. These pumps are generally made of plastic material such as polyethylene or polypropylene.
  • the pumps are preferably dual-valve, which gives them a good seal and satisfactory operation regardless of the position of the rigid container.
  • the pump generally comprises a first valve at the inlet of the metering chamber, and a second valve at the outlet, for example at the inlet of the exhaust duct.
  • each pocket is preferably attached to the container via a ring, to which it is affixed in a conventional manner, for example by interlocking, gluing or welding.
  • the ring and the pocket can be made in one piece.
  • the plastics used for the manufacture of the bags may be chosen for example from polyethylene, polypropylene, polyamide, ethylene and vinyl alcohol copolymer (EVOH), low density polyethylene, etc. They may be monolayer materials or multilayer complexes including a metal layer, for example an aluminum layer forming a barrier reinforcing the seal, combined with one or more layers of plastic material.
  • the manufacture of the bag from these materials can be carried out by techniques such as injection blow molding or extrusion blow molding of a parison in a suitable mold. It is also possible to manufacture the bag by welding a plastic or metal film, or a metal / plastic multilayer complex on a support forming the neck of the pocket.
  • each of the bags is made of a material adapted to the product it contains, and the device may therefore comprise at least two bags formed in different materials.
  • the first pouch can be made of low density polyethylene and contain a cream that is not very sensitive to the effects of the external medium, while the second pouch contains a more fragile product and can be made of a polyamide providing better protection. against the effects of oxygen and against the evaporation loss of water vapor.
  • the material used for the ring may be a plastic material of the same kind as that used for the bag, treated so as to confer sufficient rigidity, for example by using a greater thickness of material. It is thus possible to use polyethylene or polypropylene rings, the ring and the pockets being able to be manufactured in one piece, by injection blow molding or any other appropriate technique.
  • the rigid container may be made of plastic or any suitable rigid material. For example, rigid containers made of polypropylene, polyethylene terephthalate (PET), acrylonitrile butadiene styrene (ABS), glass or metal such as aluminum or an aluminum alloy can be made.
  • the dosing chamber of each pump then being preferably adapted to the volume of the corresponding bag.
  • the dosing chamber of each pump may be proportional to the volume of the corresponding bag. This is particularly advantageous in the case of dispensing complementary fluid products which must be used in specific amounts.
  • a rigid container device and two flexible bags, each communicating with a pump, according to the invention can be adapted to the mixing ratio of the two products contained in the pockets, and if this ratio must be for example 2/1, it can be expected that the volume of the second bag is equal to half of that of the first, and the same for the volume of the dosing chamber of the second pump relative to the first.
  • the pockets being placed joined by their bottom in the same rigid container, the volume of the latter is used integrally, without dead volume, even if the pockets have different volumes.
  • an outside air supply is provided in the form of a vent or an air suction circuit so that the bags can retract inside the rigid container.
  • the vent is provided in the wall of the rigid container, and it can be provided with a valve and / or a filter.
  • One or more vents may be provided.
  • the air circuit is constituted by a passage arranged in the edge of the fixing ring of each of the pumps, communicating with the space between the pumps and the pusher.
  • the air circuit allowing outside air to enter the volume between the wall of the rigid container and the pockets, is preferably designed to remain closed as long as the fluid is kept in each pocket and not open each time the pumps are operated so as to allow only one volume of air equivalent to the volume of fluid expelled from each pocket.
  • the air circuit is automatically closed, which ensures optimal preservation of the products contained in the pockets by limiting evaporation through the wall of the pockets. It therefore comprises closing means closing the circuit as the pumps are not actuated.
  • the air circuit may comprise shutter means constituted by valves, which remain closed until the pump is actuated.
  • the two-pocket device according to the present invention has the advantage of being easily filled without the need for complex tooling. It is possible to fill simultaneously the two pockets, to set up the pumps on each pocket, then to place each of the full pockets on the rigid container, or conversely to fix the two pockets on the rigid container, preferably by means of rings , fill the first pocket and fix the corresponding pump, then fill the second pocket and fix the second pump after turning the device. According to the present invention, the filling can be carried out with standard tools, by simple gravity, which ensures a very good regularity of filling.
  • each pocket retracts regularly, limiting the risk of cracking or tearing.
  • the rate of release of the product that is to say the ratio between the volume of product introduced into the bag during filling and the volume extracted during use, is excellent, and can be greater than 90%.
  • the device according to the present invention is particularly useful in the fields of application where two products must be used independently, for example alternately, such as that of cosmetic or dermatological compositions, such as creams and gels, where it may be useful to use a first product at a fixed period and a second product at another period, for example a day cream and a night cream.
  • cosmetic or dermatological compositions such as creams and gels
  • part of the rigid container of opaque material and the other of translucent or transparent material, especially when the container is constituted by the assembly of two cylinders by their bases.
  • the device of the pocket-bottle type represented on the Figure 1 comprises a rigid container (1) of cylindrical shape whose two ends are masked by two covers (2a, 2b).
  • the rigid container (1) and the covers (2a, 2b) are made of polypropylene.
  • Two polypropylene injection-molded flexible bags (3a, 3b) are inserted into the container (1) to which they are attached via the rings (4a, 4b).
  • the rings are secured to the wall of the container (1) by a known technique, for example by fitting through a rib on the periphery of each ring, cooperating with a groove formed in the inner wall of the container.
  • the pockets are assembled to the rings by interlocking their neck in the central hole of the ring, in known manner.
  • a pump (5a, 5b) of the type without air intake is placed on the neck of each pocket, by interlocking according to a conventional technique.
  • Each of these pumps can be actuated by a pusher (6a, 6b), an outlet nozzle (7a, 7b) being provided for the expulsion of the product at each actuation of the pumps when the covers (2a, 2b) have been removed by the user.
  • An air inlet circuit (8a, 8b) is provided on the edge of each ring (4a, 4b) so that air can penetrate in the volume between the pockets and the inner wall of the rigid container (1) each actuation of one or other of the pushers.
  • the user removes one or the other of the two covers (2a, 2b) and presses the corresponding pusher to obtain the product of his choice coming out of one or the other of the two pockets (3a ) or (3b).
  • the container (1) can be formed of two cylinders (1a, 1b) of the same diameter.
