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 a flexible bag placed in a rigid container, associated with a pump. or a valve, ensuring the storage of the fluid product away from air and its distribution under good conditions of efficiency.
- Devices for packaging and dispensing fluid of the bottle-pocket type are well known. These devices generally include a rigid shell container in which a flexible retractable pocket is placed, 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.
- An exemplary embodiment according to this technique is described in patent FR 2,723,356 relating to a device comprising a pocket made of flexible plastic material, such as polyethylene or polypropylene, in a rigid container whose neck has an air inlet.
- patent FR 2,770,834 Another exemplary embodiment of a pocket bottle is described in patent FR 2,770,834, which relates to a device intended to prevent piercing and tearing of the pocket during its emptying.
- the pocket made of flexible material such as plastic or aluminum foil, contains a free float preventing excessive shrinkage of the pocket and thus limiting the risks of tearing.
- the aluminum pockets are made in the form of superimposed sheets, welded by their edge, generally adapting to a neck or a rigid ring ensuring the connection with the pump, or the valve, and the rigid container.
- the manufacture of such bags is relatively simple, and various mentions and drawings can be easily printed there, but this system has the disadvantage that the sheet, before filling, has a flattened shape, requiring the use of complex tools specially adapted to be able to introduce the product.
- the filling operations generally imply having to first empty the bag before carrying out partial filling, then operating in a last step under neutral gas.
- plastic bags for example polyethylene or polypropylene bags like that described in patent application WO 97.09124, make it possible to simplify the filling operation of the bag, but do not guarantee a satisfactory seal capable of being suitable for the packaging of very fragile products degrading on contact with air.
- the extrusion or blow molding techniques used for the manufacture of such plastic bags are totally unsuitable for bags comprising one or more metal sheets.
- the object of the present invention is precisely a device for packaging and dispensing a fluid, liquid or pasty product, of the type comprising a watertight flexible pouch placed in a rigid container, associated with a pump or a valve, ensuring very good ease. filling the bag without the need for complex or specially adapted tools.
- the invention also relates to a device for packaging and dispensing a fluid product of the type comprising a sealed flexible pouch placed in a rigid container, ensuring perfect packaging of the product by means of excellent sealing of the pouch.
- the invention finally relates to a method of manufacturing a cylindrical pocket as indicated above.
- the device for packaging and dispensing a fluid product is of the type comprising a sealed flexible pocket placed in a rigid container, associated with a pump or a valve, and is distinguished in that the pocket comprises a cylindrical wall constituted by at least one metal or plastic sheet wound in a cylinder, the edges of which are tightly fixed to two flanges, one of which forms the bottom of the bag and the other a ring for fixing to the container and to the pump or to the valve.
- the cylindrical pocket comprises a multilayer complex associating several metallic films or a metallic film, preferably made of aluminum, coated with a plastic film on at least one of its faces.
- This multi-layer complex is wound on two metal or plastic flanges.
- a particularly advantageous embodiment comprises an aluminum foil sandwiched between two plastic films.
- the plastic films used in the multilayer complexes can be chosen from polyethylene, polypropylene, polyamide, etc.
- the multilayer sheet is fixed by its edges to the periphery of each flange, and closed along a generatrix of the cylinder.
- Such a multilayer composite coating proves to be particularly useful when a tight seal is essential, or when the nature of the product contained in the pocket requires it.
- the multilayer sheet is a plastic material / barrier polymer / plastic material complex, and for example an EVOH film interposed between two films of polyethylene or polypropylene.
- EVOH is an ethylene-vinyl alcohol polymer offering good barrier characteristics to gases, in particular to oxygen and water vapor.
- a four-layer complex can be used, namely polyethylene / polyamide / aluminum / polyethylene terephthalate.
- the metal sheet, or the multilayer sheet is fixed to the periphery of each of the two flanges, preferably by gluing or by welding, depending on the nature of the material used for the flanges.
- One of the two flanges forms a solid disc and constitutes the bottom of the pocket, while the other has an opening and serves as a fixing ring, on the one hand to the rigid bottle, on the other hand to the pump or to the valve used for the extraction of the product contained in the bag.
- the opening in the flange serving as a ring is preferably axial, but it can be offset, depending on the shape of the cylinder and the desired effects.
- the cylinder formed by the metal sheet, or the multilayer complex, and the two flanges is preferably a straight cylinder with circular section, the flanges then being in the form of circular disks, but other shapes can be produced without difficulty, and by example the flanges can have an elliptical shape, or any continuous or polygonal shape, depending on the aesthetic effect sought or imposed by the shape of the rigid bottle.
- the two flanges preferably have the same shape to facilitate the fixing of the metal sheet, but if necessary they can have a different shape, or a homothetic shape.
- the flanges can be metallic or made of plastic, for example by molding. he is also possible to give the flange forming the bottom a hollow shape in its center, the flange then having a toric shape, the central opening of which can be closed by the film of the cylindrical wall, or another film.
- the manufacture of the cylindrical pocket according to the present invention is carried out by means of a conventional apparatus making it possible to wind a metallic, plastic or multilayer sheet, by its edges on the periphery of the two flanges maintained on the same axis, one in opposite each other.
- the sheet is cut to the desired length, corresponding to the circumference of the flanges increased by a length sufficient to allow closing by edge-to-edge welding, after bonding of the lateral edges on the periphery of the flanges.
- the pocket bottle according to the present invention has the advantage of being easy to fill without the need for complex tools, unlike conventional aluminum pockets.
- filling can be carried out with standard tools, by simple gravity, which ensures very good filling regularity.
- the great freedom of shape of the bag makes it easy to adapt it to rigid bottles of various shapes.
- the rate of return 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, greater than 90%, and greater than that generally obtained with conventional flat pockets.
- the pocket Due to its cylindrical shape pressing on the two rigid flanges, during its use and extraction of the product contained therein, the pocket does not wrinkle as in the case of flat aluminum pockets, but shrinks regularly, limiting the risk of cracking or tearing. In addition, the number of welds is limited compared to a conventional aluminum pocket, and the reliability of the pocket is improved.
- the bag can be assembled to the bottle without prior folding, and therefore without risk of deterioration of its sealing qualities.
- the assembly of the bag to the bottle can be carried out at high rates.
- Figure 1 a sectional view of a pocket according to the present invention comprising a sheet of multilayer complex attached to a bottom and a ring of thermoplastic material.
- Figure 2 a sectional and perspective view of the pocket of Figure 1.
- Figure 3 a perspective view of the pocket of Figure 1 showing how the longitudinal welding of the aluminum foil constituting the wall of the pocket takes place.
- Figure 4 a sectional view of the pocket of Figure 1 placed in a rigid bottle with a pump.
- the pocket (1) shown in Figure 1 comprises a cylindrical wall (2) formed by an aluminum foil wound on the two flanges (3) and (4).
- the lower flange (3) has the shape of a solid disc (5) with raised edge forming an annular surface (6) on which the edge of the sheet (2) is fixed by gluing.
- the upper flange (4) has the shape of a ring crossed in its center by an orifice (7) and comprising a raised edge forming an annular surface (8) on which the other edge of the sheet (2) is stuck, limited by a rim (9) of diameter slightly greater than that of the cylindrical wall (2).
- the two edges (2 ', 2 ") of the aluminum sheet (2), cut to the desired length, are welded to each other along a generatrix of the cylinder, after bonding of the two lateral edges (2a, 2b) on the annular surfaces, (6) and (8) respectively, the flanges.
- the pocket (1) is introduced into a cylindrical bottle (10) as shown in Figure 4.
- the edge (9) of the ring (4) is fixed by snap-fastening in a groove (11) formed in the internal surface of the wall (12) of the rigid bottle.
- a pump (13) supplemented by a pusher (14) is mounted in leaktight manner on the neck of the pocket (1). Sealing can be ensured in the usual way, for example by means of an annular seal (15).
- a pressure on the pusher (14) causes the exit of a dose by the nozzle (16), causing a retraction of the bag (1).
- a vent in the bottle allows the outside air to enter the volume between the bottle (10) and the pocket (1) and the pocket to retract as the pusher is actuated (14).
- the pocket used in the device of Figure 4 has a flange (3) whose bottom is hollowed out, the opening being masked by an aluminum sheet (17) improving the flexibility of the pocket (1).
