Definitions
- the present invention relates to a device for packaging and dispensing a fluid product, and more particularly to a new device for packaging and dispensing a fluid product, liquid or pasty, of the type comprising at least two flexible bags placed in a single rigid container, associated to one or more pumps or valves, ensuring the storage of at least two fluid products protected from air and their distribution, in mixture or separately, under good conditions of efficiency.
- Devices for packaging and dispensing fluid of the bottle-pocket type are well known. They generally include a rigid shell container in which is placed a flexible pouch which retracts as the product is extracted therefrom.
- the expulsion of the product from the bag can be obtained by means of an "airless" pump, or without air intake, or under the pressure of a propellant acting in the bottle, on the wall of the bag.
- a vent is provided, generally at the bottom or in the neck of the bottle, to allow outside air to enter in the space between the bottle and the bag on each actuation of the pump and thus allow the bag to retract while maintaining sufficient pressure on its walls.
- the present invention specifically relates to a device for packaging and dispensing fluid, liquid or pasty products, of the type comprising at least two flexible waterproof bags placed in the same single rigid container, associated with one or more pumps or valves, ensuring a effective distribution of at least two products separately or as a mixture.
- the invention also relates to a device for packaging and distributing several fluid products each contained in a separate bag, ensuring very good ease of filling the bags without the need for resorting to complex or specially adapted tools.
- the subject of the invention is also a device for packaging and distributing several fluid products, of the type comprising at least two waterproof flexible bags placed in the same single rigid container, ensuring perfect packaging of the product by means of an excellent seal of the pocket.
- the invention finally relates to a device of the type indicated above, which can be manufactured under good conditions of profitability.
- the device for packaging and distributing fluid products according to the present invention is of the type comprising at least two watertight flexible bags placed in the same single rigid container, associated with at least one pump or valve, and it is distinguished in that each bag comprises means cooperating with at least one fixing ring to the rigid container and with the pump or pumps or valves.
- each pocket comprises at least one flat surface for assembly with another pocket, the pockets being contiguous by their respective flat surfaces.
- the device of the invention comprises at least two pockets combined with a single ring for fixing to the container and to pumps or valves, the ring being fixed to the pockets by any known means of fixing such as welding, bonding , snap-fastening or mechanical crimping.
- the single ring used in the invention is advantageously designed to allow the pockets to be fixed by snapping their neck onto the ring, which ensures greater ease of manufacture and assembly of the elements of the device.
- the pump, or the valve can be fixed to the bag by the same fixing means, preferably by snap-fastening.
- the two pockets are formed in a single piece and are then in the form of a double pocket comprising two compartments separated by a partition, each compartment preferably having its own opening provided with a collar for fixing a pump.
- This embodiment has the advantage of stiffening the structure of the pocket by means of the partition, which has the effect of facilitating the return of the products contained in the pockets.
- the pockets and the ring are formed in a single unitary piece, manufactured by extrusion, blowing, extrusion blow molding or injection blow molding from a suitable plastic material.
- the pumps used in the invention are non-return air pumps, of the "airless" type, as commonly used in the art.
- the plastics used for the manufacture of the bags can be chosen, for example, from polyethylene, polypropylene, polyamide, a copolymer of ethylene and vinyl alcohol (EVOH), etc. It can be monolayer materials or multilayer complexes including a metallic layer, for example a layer of aluminum forming a barrier reinforcing the seal, combined with one or more layers of plastic.
- the manufacture of the bag from these materials can be carried out by techniques such as blow molding or blow molding in a suitable mold.
- the bag can also be manufactured by welding a plastic or metallic film, or a metal / plastic multilayer complex on a support forming the neck of the bag.
- the material used for the ring may be a plastic material of the same nature as that used for the pocket, but treated so as to give it sufficient rigidity, for example by using a greater thickness of material.
- Polyethylene or polypropylene rings can thus be used, and as indicated above, the ring and the pockets can be manufactured in one piece, by injection blowing or any other suitable technique.
- the rigid container may be made of plastic or any suitable rigid material.
- the device comprises a single ring associated with several pockets, the assembly being placed in a rigid container.
- the openings made in the ring are preferably arranged symmetrically with respect to the center of the ring, but they can be offset, depending on the shape of the cylinder and the desired effects.
- the cylinder formed by the pocket does not form a body of revolution, its section not being circular, but is preferably a straight cylinder with semi-circular section comprising at least one flat lateral surface serving to join the pockets together in the same container.
- Other shapes can be produced without difficulty, for example a substantially elliptical shape, or a shape any continuous or polygonal, or even a non-cylindrical shape, depending on the desired aesthetic effect or imposed by the shape of the rigid container.
- each pump adapted to each pocket can be actuated by an independent pusher, or, on the contrary, a single pusher can be actuated simultaneously actuating two or more pumps.
- a device with a rigid container and two flexible bags according to the invention can be adapted to the mixing ratio of the two products contained in the bags, and if this ratio must be, for example, 2/1, provision may be made for the volume of the second pocket is equal to half that of the first, and likewise for the volume of the metering chamber of the second pump relative to the first.
- an outside air supply is provided in the form of a vent or an air suction circuit.
- the vent is provided in the wall, for example in the bottom of the rigid container, and it is preferably provided with a valve and / or a filter.
- the air circuit allowing the outside air to enter the volume between the wall of the rigid container and the bags, is preferably designed so as to remain closed as long as the fluid is kept in each bag and not to s '' open each time the pumps are actuated so that only one volume of air equivalent to the volume of fluid expelled from each pocket. At the end of actuation of the pumps, 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.
- the air circuit is constituted by a passage arranged in the edge of the ring, communicating with the space between the pump and the pusher, and comprising shutter means as long as the pump does not is not activated.
- the fluid products contained in the pockets can be expelled separately, when the device comprises separate pushers, or simultaneously.
- the simultaneous and controlled expulsion of fluid products is advantageous in the case of products which must be mixed extemporaneously and in predetermined proportions.
- the presence of a single pusher acting on two or more pumps facilitates this simultaneous expulsion, and the choice of pumps having suitable metering chambers ensures the composition of the mixture in the appropriate proportions.
- the metering chambers of the pumps can be proportional to the volume of the bags.
- the device of the invention may include juxtaposed or concentric product outlet nozzles, to ensure an excellent mixing of the products coming from each bag.
- the outlet pipes of the pumps can be joined together to open into a common outlet nozzle, the mixing then taking place in the nozzle.
- the pocket container according to the present invention has the advantage of being able to be easily filled without the need for complex tools.
- filling can be carried out with standard tools, by simple gravity, which ensures very good filling regularity.
- the great freedom of The shape of the pocket allows it to be easily adapted to rigid containers of various shapes.
- each pocket regularly retracts, limiting the risk of cracking or tearing.
- the product return rate 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 for packaging and distributing fluid products according to the invention is particularly suitable for products with complementary actions or activities which must only be mixed during their use while they must be kept separately to prevent them from reacting. one over the other.
- An area of application where the invention can thus be used advantageously is, for example, that of two-component adhesives, one of which is intended to cause rapid hardening of the other.
- compositions such as creams and gels, where it may be useful to carry out the extemporaneous mixing of two components which must be kept separately to prevent them from reacting with each other. 'other.
