Definitions

  • the present invention relates to a device for packaging and dispensing fluid, liquid or pasty products, and more particularly to a flexible bag device associated or not with a rigid bottle, containing a fluid, liquid or pasty product packaged under cover of the air and intended to be delivered by means of a pump or a valve, as well as a set-pocket bottle for packaging and dispensing equipped with such a device.
  • Container-type fluid dispensing and dispensing devices are well known. These devices generally comprise a rigid-shell container in which is placed a retractable flexible bag, which retracts as the product is extracted. The expulsion of the product out of the bag can be obtained by means of an "airless" pump, or without air intake, or under the pressure of a propellant gas acting in the bottle on the wall of the bag.
  • a vent is provided, generally in the bottom or in the neck of the bottle, so that the outside air can enter the the space between the bottle and the bag each actuation of the pump, thereby allowing the bag to retract while maintaining sufficient pressure on its walls while preserving the product contained in the pocket, which remains at the shelter from the air.
  • 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.
  • Pocket systems are also known whose upper part is reinforced in order to facilitate its fixing on the rigid bottle, and the patent application WO 0058021 describes a pocket following this technique but the volume of product rendered by this type of pocket is generally unsatisfactory because the deformation of the pocket is limited essentially to the cylindrical portion of its wall, and the rate of refund can not then hope to reach 90%. This is a disadvantage all the more serious that the value of the product in the pocket is greater and a significant amount of the product is then lost to the user.
  • the difficulties encountered in these known techniques are often related to the folds formed by the wall of the pocket during its retraction, which can limit the efficiency of the distribution of the fluid by forming volumes of product retention, and the difficulty of ensure a satisfactory seal of the pocket to preserve the integrity of the product contained therein.
  • the products contained in the bags are often sensitive to oxidation under the action of oxygen in the air and can degrade if air is introduced into the pocket. Sealing defects are often encountered at the junction of the bag and the pump. They can also result from a certain porosity of the materials used for the realization of the pocket.
  • the folds formed by the wall of the bag during its retraction can cause tears likely to let air that then reaches the product in the pocket.
  • a pocket bottle is described in the patent FR 2.770.834 , which relates to a device for preventing the piercing and tearing of the bag during its emptying.
  • the pocket made of flexible material such as plastic or aluminum foil, contains a free float preventing too much retraction of the pocket and thus limiting the risk of tearing.
  • Devices of this type have the disadvantage of not ensuring a release of all the product contained in the bag and consequently to cause significant losses of product.
  • Pockets are also known whose lower part comprises several bellows.
  • the document FR 2,669,306 describes a pocket with a bellows bottom portion, which is gradually housed in the frustoconical volume of the rigid upper part, without being pressed to it.
  • Another example is described in the patent GB 2.083.142 which relates to a pasty product applicator having a retractable pocket comprising a plurality of bellows.
  • the pumps generally associated with the flexible bags must ensure a good seal and be able to work both in vertical position and inclined position.
  • the patent FR 2,669,379 describes a metering pump providing good sealing even in the case of a change of position, of the axial piston type carrying a sliding floating piston, comprising three valves.
  • the patent FR 2.726.810 describes an example of a pump without air intake in which the lower valve is flexible and frustoconical while the upper valve is carried by a disk placed at the base of the hollow rod of the pusher.
  • the present invention relates to a deformable flexible pouch, capable of containing fluid, liquid or pasty products, associated with means for ensuring the distribution of said products without air intake in the pocket.
  • the subject of the invention is also a device for packaging and dispensing fluid, liquid or pasty products, such as a rigid bag with a flexible bag, comprising a flexible bag as described above, ensuring excellent reproduction of the product contained in the invention. pocket, regardless of the position of the rigid bottle.
  • the present invention also relates to a deformable flexible pouch intended to be fixed in a rigid bottle carrying a manual pump without air intake sealingly fitting on the opening of the bag.
  • the subject of the invention is also a device for packaging and dispensing fluid or liquid products of the rigid vent-type type, comprising a flexible bag as described above, mounted in a sealed manner on a bottle provided with a vent , and associated with a device for extracting and dispensing the product contained in the pocket.
  • the deformable flexible pouch is of the monobloc type, capable of containing fluid, liquid or pasty products, comprising a rigid upper part comprising an opening neck and a flexible and deformable lower part, associated with means for to ensure the distribution of said products without air intake in the pocket, the two parts being hinged to each other so that the top of the inner wall of the lower part comes to press against the inner wall of the upper part when retracting the pocket.
  • This pocket is distinguished in that its flexible lower portion has a constriction forming a bellows having a shape such that it folds on the inner wall of the rigid upper part when it retracts, said constriction being formed in the upper part of the flexible pouch.
  • the presence of a single constriction in the upper part of the flexible bag has the advantage of allowing easy filling of the bag, and whatever the viscosity of the product used.
  • the internal diameter of the throat is slightly greater than the diameter of the neck of the pocket.
  • the rigid upper portion of the bag has a substantially frustoconical shape, and its rigidity is sufficient to prevent any deformation of this portion of the bag during the retraction thereof.
  • this upper part of the pocket has a dome shape, opening in its center to connect to the neck of the pocket.
  • the top of the flexible lower part of the pocket has a constriction, as indicated above, arranged such that the wall of the pocket adjacent to this constriction, on the side of the neck of the pocket, is of substantially frustoconical shape, the base of this flexible cone trunk connecting to the base of the rigid frustoconical upper part according to the area of articulation of the two parts with each other.
  • the diameter of the base of the rigid upper part supporting the zone d articulation with the lower part of the pocket is slightly greater than the outer diameter of the connection area of the constriction with the side wall of the pocket, so that after folding of the top of the flexible lower part of the pocket against the rigid upper part, the base of the latter protrudes slightly beyond the wall of the lower part of the pocket.
  • this embodiment has the advantage of constituting a bearing zone capable of coming into contact with a shoulder formed in the top of the wall of the bottle, to facilitate the positioning of the bag in the bottle.
  • the base of the flexible bag has a concave shape, reinforced by a diametrical cross member which facilitates the maintenance of this part of the bag when it retracts.
  • the flexible lower part of the bag is designed so that it retracts in a two-step movement, by first folding against the inner wall of the rigid upper part, and then ensuring a movement up the bottom of the pocket to the neck.
  • the flexible pouch according to the present invention has the advantage of having a rigid upper portion associated with a flexible lower portion, the shape of which, during the retraction of the bag as the extraction of the product which is there content, is complementary to that of the rigid part so that the rate of return of the product, that is to say the ratio of the extracted amount to the amount initially contained in the bag, is greater than 95% and even greater than 99% depending on the nature of the product contained in the flexible pouch.
  • the upper portion of the pocket combines good stiffness and relatively low thickness while the lower thickness of the lower portion in fact a real flexible pouch that can completely retract and not just a flexible bottle.
  • valve pumps which can function in a variety of orientations can advantageously be used.
  • the valves of the pump can be made of any material having the desired characteristics of flexibility and elasticity, and compatible with the products contained in the bottle.
  • the pump may be advantageous, in accordance with the invention, to mount the pump in a sealed manner on the rigid bottle containing the flexible bag, via a ring or a cover.
  • the pump is mounted directly on the bottle, by any usual technique, for example by interlocking, latching, gluing, welding or screwing.
  • the pump is mounted on a ring secured to the neck of the bag and resting on the edges of the bottle, in the form of an open cylinder.
  • the edges of the opening of the bottle comprise means cooperating with the ring to ensure its attachment.
  • the fixing of the pump to the ring can be done by the same technique, or by welding.
  • the ring can be integrated in the neck of the pocket and formed with it.
  • the pump is mounted directly on the neck of the pocket.
  • the good rigidity of the upper part in the form of a truncated cone or of dome, is sufficient to allow the establishment of the pump and its maintenance during use.
  • This feature of the invention is advantageous because it avoids having to use an intermediate ring. Such a ring can however be used in particular configurations involving a strengthening of the structure carrying the pump.
  • the bag In the absence of an intermediate ring, the bag is held in place on the rigid bottle by snapping or screwing, by means provided on the periphery of its rigid upper part and cooperating with the upper edge of the bottle, for example grooves formed in the periphery of the ring, corresponding to ribs in the inner wall of the bottle, or vice versa.
  • the bag is simply placed on the opening of the bottle, the periphery of its rigid upper portion resting on a shoulder formed in the inner wall of the bottle. The assembly is then locked in position by the body of the pump which is fixed on the opening of the rigid bottle, by usual means, over the pocket.
  • the pocket is itself fixed by interlocking or clamping on the plunger tube of the pump.
  • the rigidity of the upper part of the pouch is generally considered a disadvantage because it opposes the complete retraction of the flexible pouch and thus reduces the rate of restitution.
  • the present invention takes advantage of this rigid structure to facilitate the introduction of the bag on a rigid bottle, optimizing the folding of the pocket following a movement that adapts to the rigid structure, so that the refund rate is greater than 95%.
  • the rigidity of the upper part of the pocket and the flexibility of the lower part are obtained for example by giving an appropriate thickness to the wall of each of these parts, formed in a single block of the same material. For a same thickness, the rigidity also varies in known manner depending on the shape of the wall.
  • this air circuit is located at the pusher of the pump, and comprises means to ensure its closure when the pusher is raised, in the rest position.
  • the air circuit may consist of a vent, preferably in the bottom of the bottle.
  • a vent provided with a valve, to prevent leakage of the product contained in the bottle, and a filter to prevent the introduction of pollutants, such as that bacteria, which could degrade the product to be distributed.
  • the venting is formed by one or more longitudinal grooves formed on the periphery of the base of the rigid upper part of the pocket, in the articulation zone between the upper part and the lower part.
  • one or more openings are made in the ring to allow the passage of air.
  • a hood or cap removably mounted on the dispensing head.
  • Means may be provided for sealing the mounting of the cap on the head, and for example the cap may be inserted by interlocking due to a complementary shape of the inner edge of the cap and the base of the nose of the pusher receiving this assembly being supplemented by an O-ring or sealing gongs.
  • Such an accessory completing the pump and its pusher ensures excellent sealing in all storage conditions, even in the event of a drop in the external pressure, and ensures the preservation of the product contained in the bottle.
  • the pump fixed by means of a ring or directly on the neck of the flexible bag of the invention, is generally made of plastic such as polyethylene or polypropylene of appropriate density to impart the desired mechanical properties.
  • the bag may be made of a plastic material selected for example from polyethylene, polypropylene, polyamide, ethylene vinyl alcohol copolymer (EVOH), low density polyethylene, polyethylene terephthalate (PET), polyvinyl chloride (PVC), polyurethane, 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 bag can be manufactured by blowing techniques in one piece from the above materials, which substantially reduces the investment required for manufacturing, and therefore to reduce the manufacturing cost.
  • the process of making a pocket monobloc blow molding or extrusion blow molding also avoids having to make a molded component and remove an assembly operation compared to a conventional technique.
  • the flexible pouch according to the invention is preferably made of a material adapted to the product it contains.
  • a material adapted to the product it contains may be of low density polyethylene when it must contain a cream that is not very sensitive to the effects of the external environment, while it may be made of a polyamide providing better protection against the effects of oxygen and against the evaporation loss of water vapor, when it must contain a more fragile product.
  • the thickness of the wall of the pocket varies according to the desired rigidity for the upper part and the flexibility for the lower part, and depending on the material used. Suitable material thicknesses can be readily determined by those skilled in the art. For example, in the case of a polyethylene or polyamide wall, the thickness of the neck of the pocket may be between 0.5 and 1.5 mm, that of the rigid upper part between 0.2 and 0, 3mm and that of the flexible lower part between 0.1 and 0.2 mm.
