Definitions
- the present invention relates to a new type of packaging for food or non-food products, produced in liquid form or which may flow from analogous to a liquid, and products belonging more particularly to consumer goods, these packaging (generally used unique) being likely to be used manually by natural persons (adults or children).
- This invention therefore applies in particular as well to packaging. of liquid foods such as milk, various drinks or vegetable oils by example, than packaging of non-food liquids such as motor oils, liquid product for dishwasher, liquid unblocker, etc. ; it applies also to packages of products containing powder, granules or aggregates, food (flour, sugars, flakes, etc.) or non-food (detergents for example) likely to flow analogously to a liquid.
- This invention can be applied to any type of packaging, bottles, boxes, cans, and whatever its constituent material (polymer, glass, metal, paper or cardboard, textile, fiber, plant material, or complex produced from some of these materials).
- minimum holding has therefore often become a “minimum holding” and insufficient, and it is not uncommon to see packaging of the type: milk can or fruit juice, for example, "make the belly” under the load of the objects placed on it, or when you want to use this type of box, holding it at the hand involving finger pressure on the walls, we do, after opening and almost without fail, "squirt" the product in an uncontrolled way out of packaging.
- bottles of drinks with very thin polymer walls very easily crushed on hand and the liquid spreads as much on the table as in the glass.
- Another well-known device which now equips a number important cardboard boxes, milk, fruit juice or various drinks, consists of a shutter that can be locked with one or more material clips plastic generally lined below by a tab (itself in plastic or metallic material), tongue that is pressed most often to create the opening of the box, the shutter fixing by one or more clips, allowing to close the box after partial use.
- the shutter is of certain interest, however the tongue, which remains attached to this reported "neck” and which, in certain cases, creates, according to the position it takes after pushing in, some interesting braking of the liquid flow through the neck when you are in the pouring phase, do not not really regulate this flow of liquid; further and on the contrary, according to its position, it can cause the liquid to come out insufficiently, deflected, or anarchic with respect to a normal direction of flow; including the liquid can partially "run” along the outside of the box which does not not allow to respect the hygienic conditions that we are entitled to expect packaging; moreover, at the time of the insertion of this tab, the user often makes the liquid squirt, or puts it in physical contact with one of his fingers or any object used for this insertion, which, there still, does not guarantee sufficient hygiene.
- This device like those of the same family mentioned above, improves of course the regularity of the liquid outlet flow; however, if the wall of the packaging is thin and if the packaging is tightened a little too irregularly by a clumsy hand, it will not prevent an uncontrolled exit of the product (squirt under pressure of the hand), or, if the packaging is too inclined, the flow will be immediately (and thanks precisely to the air intake) very important, which is not necessarily sought by the user.
- the present invention aims to remedy very sensitively all of these disadvantages. It relies for this on the hydrodynamic brake phenomenon created by a deflector placed in a flow, and which, applied judiciously to the field of product packaging preferably consumer goods gives quite amazing and interesting results and benefits.
- the hydrodynamic brake phenomenon created by a deflector placed in a flow is well known in the field of fluid mechanics (or mechanics of products behaving like a fluid), it implies that it there is a fluid flow with a general direction of flow and a deflector which comes, by the disturbance it creates in the flow, to play a role of brake and regulator in this flow (the more the deflector is in a transverse position at this flow or more its section is large compared to the flow section the more "braking” and "regulation” are important).
- the vacuum zone "retains" the fluid and the more the fluid tends to go fast, the greater the dynamic depression at the rear of the deflector and therefore the more the fluid is “retained”, which has the general physical effect, excellent flow regulation.
- the "hydrodynamic brake” that we are talking about here is well known in mechanics or fluid dynamics, and the present invention consists, basically, but with a number of technical options described below, by installing a deflector inside a package in an approximately transverse position relative to the general direction internal liquid flow when you want to use or consume it, which allows in particular to regulate said flow. So if we suddenly tilt for example a box of milk or any drink provided transversely, to inside, of a deflector according to the invention, as usual, impulses are a high speed to the fluid, but this will be immediately and automatically braked and therefore regulated thanks to internal friction and depression which is instantly created at the rear of the deflector and which retains the fluid. If the milk container does not have this type of deflector, an inclination or a strong pressure on the box makes the liquid squirt out of the packaging with a great speed.
- the invention provides a packaging device such as defined in claim 1.
- the preamble to claim 1 is based on the state of the art according to FR-A-1462362.
- This deflector is made either of the same material as that of the packaging, either by another material (polymer, metal, glass, paper, cardboard, textile, plant material or complex of these materials) and it is preferably rigid or semi-rigid.
- obtaining this or these deflector (s) can advantageously be made from the same material as that constituting of the packaging and simultaneously with the operation of obtaining the packaging (a simple modification of the mold is sufficient), which is particularly economical and does not creates no significant additional cost.
- the deflector is placed inside the packaging and is not preferably not in direct contact with the neck or the outlet of the product so that the phenomenon of depression which occurs downstream of the deflector (s) plays its role too close to the outlet, and therefore of the pressure atmospheric, would be harmful for a good regularity of flow; otherwise, he could, if he was too close to the outlet, take on too easily bacteria in case of partial use of the product contained in the package, which would harm the hygienic preservation of the product.
- one of the advantages resulting from the installation of this or these deflector (s) inside of packaging and not in direct contact with the outlet is that, the disturbances likely to occur when the liquid flows produce at the level of the internal passage section left free by the deflector or just downstream of the deflector, and no longer in the vicinity of the outlet; when the liquid arrives at the outlet, its flow has already been "broken”, “calmed” and regulated by the (s) deflector (s) (analogy with one or more dams on a river).
- the packaging It is fixed by gluing, welding or stapling for example, or can be constituted by a variation in the shape of the packaging (in this case it can also play a role in thermal diffuser contributing to the faster heating of a drink contained by it for example, or it can easily be combined with a handle also integrated in the packaging); it is advantageously located in the half the volume of the package with the drain opening (s) of the product contained, and the total sealing surface of the deflector (s) is preferably greater than sixty percent of the cross section of the package (transverse means along a plane perpendicular to the general axis of the packaging which is most often the general axis of product flow).
- transverse tab internal (s) rigid (s), semi-rigid (s) or flexible (s) or even a partitioning trellis partially inside the volume of the packaging;
- the passage area main left free by the deflector thus formed will preferably be partly low when the packaging is tilted for product flow, so as not to "trap" product upstream of the deflector and be able to empty easily and completely packaging; in addition and preferably, at least one hole or one small passage section in the upper part will be provided so that the air, which is returned also inside the packaging during the pouring of the product, can pass in the upper part from one side to the other of the deflector thus helping to regulate the filling or flow rate.
- the outlet opening of the packaging allowing the product to flow will be of fairly large section, the deflector ensuring a non-excessive flow, this fairly large opening facilitating the air inlet in the packaging, air inlet which is obviously necessary from the made the product release.
- the optimal shape and inclination of the internal deflector (s) will be determined as well as the internal passage section left free by the deflector and the section opening for product flow out of the packaging.
- the deflector may consist of two tabs each linked to a wall of the package, these two walls facing each other, and the two tabs do not not touching, or only partially touching, leaving a section of passage between them for the product to be disposed of. In all cases, the effect of partition partially retains the product during its flow and regulates almost automatically this flow regardless of the movements printed at the packaging by the hand of the user during the flow of the product.
- This or these tab (s) can or (can) constitute in its or (their) generally forms a complete partition, it (s) will be (or will be) in this case fitted (s) passage holes of sufficient size to allow product to flow on the one hand and advantageously the passage of air from one face to the other on the other hand. It (s) may or may also constitute an incomplete partition, but it (s) preferably constitutes, as said above, a filling greater than sixty percent of the general internal section of the package, or even greater than eighty percent (the greater the fluidity of the product, the more the deflector must have a large filling).
- a deflector In the case where a deflector is linked to the two internal side walls of packaging facing each other, or more than forty percent of the internal perimeter in the case of a circular section, it prevents their separation under the action of the dead weight of the product or under the action of the various masses likely to be placed on the packaging containing the product. It thus prevents the phenomenon of "belly" and the risk of bursting observed on packaging as soon as it is little too thin or too weak given the loads they have to bear and thus gives either better safety to the packaging, or a possibility of reduction in thickness of the walls of the same security packaging.
- packaging with an integrated handle includes general a narrowing of the section to the right of the area where the handle but this is usually only five to thirty percent of the general section of the packaging and is not really a deflector sufficient.
- the deflector device according to the invention can be of general shape flat, ribbed, or itself comprise several bosses, walls, fins or holes of various shapes (cut holes, conical holes, stamped or other). he will be best adapted to the flow of the product according to the shape and size terms of packaging and according to the nature of the product packaged.
- the deflector may be geometry or orientation variables to perfect the flow regulation according to the quantity of product remaining in the packaging, or possibly to constitute a second sealing, inside the packaging itself, which has the advantage of being able to close the packaging internally when the product is partially consumed, this in trapping less air above and therefore better preserving the initial quality of the product contained.
- the deflector consists of a rigid or semi-rigid material and it constitutes at least one stiffener transverse of the packaging in an area close to where the hand of the user grasps the packaging to dispense the product.
- This stiffener contributes thus the holding of the packaging not only thanks to its tensile strength, but also to its compressive strength. To this end, it may be either sufficiently rigid in itself (sufficient thickness and strength of its material), be rigidified by any suitable means (ribs, reinforcement, etc.) and thus constitute a spacer or stiffening element of the packaging.
- deflector / stiffener thus formed is, in addition to the advantages of regularity previously mentioned, that it makes it possible to further thin the walls of the packaging concerned to a large extent.
- packaging with very thin walls, or even a completely flexible packaging can, thanks to the internal rigid deflector / stiffener, as described here, combine on the one hand sufficient resistance to crushing pressure exerted by the user's hand or by shocks and pressures due in particular to transport or storage, and other share a perfect regularity of flow and an easy compaction possibility before filling or after use.
- the art can in a single operation easily obtain rigid deflectors and thin wall thicknesses of the packaging where they are desired by playing on the temperatures of the mold and / or on the thicknesses of metal walls of the mold.
- the present invention overcomes all these drawbacks in this case; in effect, the fact of providing inside the box and, preferably linked to the walls internal, a semi-rigid or rigid deflector for example, avoids both the phenomenon of "belly” than that of "hollow” and therefore of thinning the walls, therefore of to facilitate the simply manual tearing (without cutting tool) of the folded part which then traditionally serves as a spout, and this deflector also allows, of course to regulate in a large proportion the flow. This type of packaging then becomes almost perfect in use.
- boxes, cans or bottles according to the invention can be formed a completely flexible envelope comprising one or more internal transverse deflectors / stiffeners.
- the flexible material of the envelope is an elastomer
- the advantages are numerous but the cost of an elastomer generally being greater than the cost of a classic thermoplastic material, it will sometimes be beneficial to design the packaging as being reusable (sufficient wall thickness, etc.).
- the can or the bottle contributes to ensure the mechanical strength of the assembly thanks to the tensile preload exerted by the pressure in the flexible walls.
- the deflector (s) / stiffener (s) allows (in particular) to prevent the product from spurting suddenly out of packaging at the opening of the neck or outlet, which would occur almost certainly if this type of packaging was not equipped with deflector (s) / stiffener (s) (this, in particular, explains that we only found very few flexible or elastomeric packaging on the market despite their benefits otherwise); the deflector / stiffener overcomes this drawback.
- the flexible packaging thus formed can, after partial use, shrink also in section and come, if the deflector / stiffener is large enough and of adequate position and shape, tighten all around the free periphery of the deflector (s) / stiffener (s) which ensures a fairly good seal when closing above the remaining product, thereby ensuring better conservation of the said product.
- Figure 1 shows schematically in section a liquid (26) flowing upstream of a deflector (27) in a tube (25).
- the liquid (26) which is driven by a certain speed passes in the passage zone (30) left free by the deflector (27) and flows into the zone (29), its general flow being regulated by to pressure losses caused by the deflector (27) and thanks to the vacuum dynamic (directly related to the speed of the liquid) which is created in the area (28) immediately downstream of the deflector (27), depression which "retains" the liquid in function of its own speed and therefore helps regulate its said speed.
- FIG. 2 represents a front view of a conventional bottle with rigid or semi-rigid walls (1) equipped with a neck (2).
- Figure 3 shows in section along a vertical plane passing through the axis AA a conventional polymer container capable of containing a liquid, container generally obtained by extrusion blow molding and provided with an integrated handle (3).
- zone (4) corresponds to a narrowing of the general section of the container perpendicular to the axis AA which does not exceed thirty percent of the said section and which, as such, does not really play a deflector role for control the flow of the liquid.
- Figure 4 shows in perspective a conventional milk box provided folds (2b), one of which can serve as a spout after unfolding and cut or tear, box which here is full of milk and which shows a phenomenon of "belly" in the central part of the walls (1b).
- FIG. 5 shows in perspective a can of engine oil with here metallic walls (1c), canister provided with a neck (2c) itself fitted with a tube flexible polymer (2d) intended to facilitate the pouring of oil into the engine, but device which does not regulate the phenomenon of uncontrolled flow of oil due to the mass of oil loaded above the neck during the pouring operation engine oil and due to the "jerky" entry of air into the container.
- FIG. 6 represents a deflector (5) which may be metallic, plastic, cardboard or other, generally planar, provided with two fins (6) intended to facilitate its fixing inside the packaging it concerns.
- Figure 7 is a representation of a deflector of the type of that described in Figure 6 but having a rear fin (6a) for fixing instead lateral fins and further comprising transverse ribs (5a) intended to play a role on the regularity of flow of the product, but also to allow, in the case of flexible bending of the ribs, an extension or retraction of the deflector thanks to the small cords (6u) and (6v) whose free end can be brought back to the outside of the package.
- FIG. 8 is a representation of a deflector of the type of that described in Figure 6 but having a rear fin (6a) for fixing instead lateral fins and comprising a hollow rib (7) playing a role both stiffening of the deflector and air passage.
- This deflector further comprises a "stamped" type hole (8).
- Figure 9 is a representation of a deflector of the type of that described in Figure 6 but having a main face (5c) provided with orifices passage (9) and (9a) for the product and holes (10) for the passage of air.
- Figure 10 shows a deflector of the type described in Figure 6 but having a main face (5d) curved along a radius (R) for it provide better transverse rigidity and to facilitate regularity of flow.
- FIG. 11 represents a deflector capable of being integrated into a circular section packaging (bottle for example). It has a side here main plane (5th) bordered by a circular fin (6b), the main face (5th) being truncated here along the straight line (11) to allow in particular the passage to liquid and air.
- FIG. 12 represents a polymer bottle (polyethylene, terephthalate, polyvinyl chloride, etc.) obtained here by conventional process extrusion blow molding; in addition to its neck (2) provided with a conventional thread, the wall (1) was shaped in the mold around two tabs which thus made it possible to constitute the two deflectors (5f) and (5g) each with a double wall, shaped so that they respectively leave the passage sections (11f and 11g) for the liquid in one direction, and for air in the other direction during the evacuation of the liquid.
- the wall (1) was shaped in the mold around two tabs which thus made it possible to constitute the two deflectors (5f) and (5g) each with a double wall, shaped so that they respectively leave the passage sections (11f and 11g) for the liquid in one direction, and for air in the other direction during the evacuation of the liquid.
- FIGS. 12bis and 12ter represent a bottle of the type described in FIG. 12 but with deflectors inclined in the other direction relative to the plane perpendicular to the general axis of the bottle, and with, in addition, reinforcement links respectively ( 19f) for the deflector (5f) and (19g) for the deflector (5g).
- reinforcement links coming from molding during the extrusion-blowing operation is to "mechanically" bridge "the two faces of each deflector so that the bottle does not” open “around the end lines (20f) or (20g) but also these linkages being hollow and having a passage opening of a few square millimeters in section, they allow the air to circulate in a controlled manner in the upper part (when the bottle is inclined for pouring the liquid ), which regulates its passage above the level of the liquid and thereby contributes to regulating the rate of exit of the liquid during pouring.
- Figure 13 shows a perspective view of a bottle (here consisting of a thin and completely flexible transparent envelope of the type polyvinyl chloride for example, flexible envelope which has been heat-sealed (at using a high frequency generator for example) around a rigid assembly made of injected thermoplastic (polypropylene or polyethylene, polychloride rigid vinyl, etc.) rigid assembly itself consisting of a rigid neck (2d) fitted with an external thread to receive a screwable plastic cap, neck which is extended by three frames (2e, 2f, 2g) conforming to the general profile of the bottle and which rigidly connect two rigid baffles themselves (5h and 5i), these deflectors having a limit (11h) for (5h) and (11i) more important for (5i) allowing the liquid to circulate in a controlled manner when the bottle contains liquid and is tilted for a payment of liquid outside, deflectors each provided in the upper part (during operation (10h) for (5h) and (10i) for (5i) for regulated passage from the air which
- the deflectors (5h) and (5i) have a general truncated elliptical shape, the shape elliptical (5'h) or (5'i) being chosen to cooperate with the cylindrical shape internal of the flexible casing (1d) and with the inclination of the deflectors relative in the plane perpendicular to the general axis of the bottle.
- the flexible envelope (1d) is otherwise welded or glued in a leaktight manner to the base of the neck (2d) and is conventionally fixed (welding or bonding) inside a rigid bowl (2h) (well known base system).
- FIG. 14 shows another type of bottle here consisting of a rigid external frame made of injected thermoplastic, itself comprising eight vertical telescopic tie rods (14) integral with two octagonal rings (15a) and (15b) with a rigid neck ( 2i) by means of the rigid truncated cone (16), external rigid frame into which an envelope (1e) of elastomer (of the natural rubber, butadiene, neoprene, silicone, nitrile or other type) has been introduced, the envelope fixed so waterproof (here bonding more tightening by means of the inner ring (2j), to the rigid neck (2i), and envelope itself waterproof and which here comprises a flexible deflector (5j) of the same basic material as that of the envelope (1e), roughly planar deflector, of truncated elliptical shape, adhesive on the non-rectilinear part of its contour inside the wall (1e) by vulcanization or by thermobonding for example).
- an envelope (1e) of elastomer of the natural
- This bottle is obviously "unbreakable” for its waterproof part, and, the constituent material of (1e) and its thickness having been judiciously chosen, it allows thanks to a filling under pressure to contain the desired quantity of liquid (like a balloon that we would inflate) while then reducing volume during the use of the liquid, which, in addition to the gains in volume in intermediate storage or household waste, avoids having too much air trapped above the liquid like what exists when a classic partially emptied bottle is stored, which generally greatly affects the quality of the remaining liquid (degasification, oxidation, etc.).
- the telescopic tie rods (14) can adapt them to the strict length required .
- Figure 15 is a sectional view of a box provided with a neck outlet (2am) and two deflectors (5p) and (5r).
- This box was obtained by the rotational molding or extrusion blow-molding technique which made it possible to obtain it quickly in a single operation and which allowed to give it two thicknesses different: one, classic (from five to ten tenths of a millimeter) at the deflectors (5p) and (5r), and of the corresponding peripheral zone (1ae), and the other, much weaker (less than two tenths of a millimeter) for the whole rest of the box (1am).
- Figure 16 is a sectional view of a prismatic packaging box of injected-blown polymer comprising a pouring spout (2a) and a deflector (5k) combined with an integrated handle (3).
- Figure 17 is a front view of a prismatic packaging box in injected-blown polymer comprising a pouring spout (2a) and a deflector (51) come from molding.
- Figure 17bis is a sectional view of a cardboard packaging box provided with a pouring spout (2a) and a deflector consisting of a cardboard sheet rectangular folded so as to constitute two faces (5m) and (5n) and a triangle in side view after fixing by gluing the tabs (6b) and (6c) on an internal face of the box.
- Figure 18 is a sectional view of a metal can of oil for automobile engine fitted with a neck (2c) and a deflector (5) fixed by welding by points thanks to its lateral tabs (6) inside the container.
- Figure 19 is a side view of a prismatic packaging box (1b) of complex cardboard / metal / polymer material provided with a pouring spout (2b), box inclined at an "alpha" angle with the horizontal level in order to drain the liquid (12) in the container (13).
- This deflector / stiffener (5) does not not completely partition the inside of the box; it leaves the passage openings (11s) and (11t) for air and liquid (12), and it plays both a regulatory role of flow and increase in resistance of the box.

Description
- la maítrise et la régularité de l'écoulement d'un produit hors de son emballage, malgré une manutention manuelle pouvant être malhabile,
- le coût le plus faible pour l'emballage,
- et d'autres considérations additionnelles mais importantes concernant ledit emballage (attrait esthétique, compactage possible, considérations écologiques, impératifs pour le distributeur, etc.), mais il est de fait que tous ces dispositifs ne respectent qu'imparfaitement ou que partiellement cet ensemble de critères.
- des dispositifs permettant de créer un petit orifice supplémentaire, avec ou sans bouchon, généralement en partie "haute" de l'emballage, permettant à l'air de passer de l'extérieur à l'intérieur de l'emballage,
- des dispositifs consistant en un petit tuyau placé près du, ou dans le, goulot ou orifice de sortie et permettant de faire communiquer l'intérieur de l'emballage avec l'atmosphère extérieure au cours de l'opération de versement,
- des dispositifs analogues mais intégrés à l'emballage lui-même ;
Cependant, le problème de régulation de débit qui se pose pour la plupart des emballages de produits de grande consommation ne peut être réglé par ces moyens décrits ici.
Il existe également des dispositifs de séparation de liquides au sein même d'un emballage comme celui décrit dans le document US.A.1 955 853 (L. LAWSON et AL.). La séparation est ici réalisée au moyen d'une coupelle souple ou semi-rigide reliée à une tige extérieure, mais ce dispositif à applications réduites ne règle pas notamment le problème général d'écoulement d'un produit hors de son emballage ; de plus il est encombrant et peut poser des problèmes d'étanchéité.
Dans un autre document, de référence EP.A.0 368 757 (Société ALIZOL), il est décrit un emballage souple muni de raidisseur(s) interne(s), mais si ceux-ci permettent à l'emballage de se tenir sur sa base, même lorsque le produit qu'il contient est partiellement ou totalement consommé, ils ne confèrent pas vraiment à l'emballage décrit une solidité suffisante pour résister à des pressions exercées par les mains d'utilisateur(s) plus ou moins malhabile(s), et le produit liquide a toutes les chances de gicler inconsidérément hors du dit emballage. Pour limiter ou réduire ce problème, il est prévu dans ce document la création d'une chambre séparée obtenue au moyen d'une soudure transversale et permettant un dosage du produit. Mais là encore, il s'agit d'un cycle discontinu (versement/redressement ou versement/compression manuelle) qui ne permet pas de régler notamment le problème général d'écoulement continu d'un produit hors de son emballage.
Ces armatures-liaisons venues de moulage lors de l'opération extrusion-soufflage ont pour but de "ponter" mécaniquement les deux faces de chaque déflecteur afin que la bouteille ne "s'ouvre" pas autour des lignes d'extrémités (20f) ou (20g) mais également ces armatures-liaisons étant creuses et présentant un orifice de passage de quelques millimètres carrés de section, elles permettent à l'air de circuler d'une façon maítrisée en partie haute (lorsque la bouteille est inclinée pour versement du liquide), ce qui régule son passage au-dessus du niveau du liquide et contribue par là même à réguler le débit de sortie du liquide au cours du versement.
Cette bouteille est évidemment "incassable" pour sa partie étanche, et, la matière constitutive de (1e) et son épaisseur ayant été judicieusement choisies, elle permet grâce à un remplissage sous pression de contenir la quantité de liquide souhaitée (comme un ballon de baudruche que l'on gonflerait) tout en rediminuant ensuite de volume au cours de l'utilisation du liquide, ce qui, outre les gains de volume en stockage intermédiaire ou ordures ménagères, permet d'éviter d'avoir une trop grande quantité d'air emprisonné au-dessus du liquide comme ce qui existe lorsque l'on stocke une bouteille classique partiellement vidée ce qui nuit généralement grandement à la qualité du liquide restant (dégazéification, oxydation, etc.). Ici en l'occurrence, au fur et à mesure de la consommation de liquide et de la réduction de volume de l'enveloppe (1e), l'on peut aisément comprimer les tirants télescopiques (14) pour les adapter à la stricte longueur nécessaire. Cette solution d'enveloppe élastique est ici possible sans qu'il y ait de "giclement" à l'extérieur dès que l'on ouvre la bouteille grâce au déflecteur (5j) qui interdit tout mouvement rapide de liquide, cette garantie étant accrue par un choix judicieux de l'élasticité et de la tenue mécanique de l'enveloppe (1e).
Le caractère télescopique des tirants (14) peut être remplacé par un caractère sécable ou fragile de l'armature rigide externe, afin de réduire le volume après utilisation.
