Abstract

This packaging device for consumer use for food or non-food products, liquids, powders, or in aggregate form, capable of being used by natural persons, adults or children, comprises at least one deflector located at the interior of the general overall volume delimited by the packaging and partially partitioning the interior of the packaging, deflector making it possible in particular, thanks to the hydrodynamic brake phenomenon that it constitutes, to regulate the flow of the packaged product that is wants to use or consume and also allowing, when it is sufficiently rigid, to play a role of stiffener and reinforcement for the entire packaging, which allows in particular the reduction of the thicknesses of the other walls of the packaging or the choice of deformable materials.

Description

PACKAGES FOR LIQUID, POWDERY PRODUCTS

OR IN THE FORM OF AGGREGATES

  The present invention relates to a new type of packaging for food or non-food products, preferably produced in liquid, pulverulent or aggregate form, but more particularly belonging to the field of mass consumption, and packaging (generally for single use) capable of '' be used manually by natural persons (adults or children), as well as a device to regulate the flow of the product out of the packaging, when

  you want to consume or use the product.

  This invention therefore applies in particular as well to edible liquids of the milk, various beverages or vegetable oils type for example, as to non-edible liquids of the motor oil type, liquid product for dishwasher, liquid unblocker, etc .; it also applies to powdered products, granules or aggregates, food (flour, sugars,

  flakes, etc.) or non-food (detergents for example).

  This invention is capable of being applied to any type of packaging, bottles, boxes, cans, and whatever its constituent material (polymer, glass, metal, paper or cardboard, textile, fiber, vegetable material, or complex produced at from

some of these materials).

  Traditionally used packaging is either

  rigid, either flexible or semi-rigid.

  For practical, ecological and economic reasons, the wall thicknesses of the packaging are increasingly reduced; research relating to the constituent materials generally goes, and for these reasons, in the direction of a greater mechanical resistance with often

  use of multilayer materials, integration of layers

  barriers' etc., but the limits are unfortunately quickly reached; in addition to the ecological requirements linked to the destruction or recycling of packaging after use (which reduces the possible choices of the materials making up the packaging), the requirements specific to each packaging: chemical and mechanical resistance to the product it contains and to ambient air (humidity, ultraviolet, etc.), sufficient mechanical strength to allow its storage, stacking or handling, sufficient mechanical strength to allow its manual handling including by inexperienced or clumsy hands (children, example) taking into account its consumer vocation ', means that the packaging still requires a significant amount of constituent material. Indeed, the packaging which contains a certain quantity of product must have a minimum of 'hold' in itself (this is besides, besides aesthetic considerations one of the reasons for which completely flexible packaging does not occupy only a minority share in the wide range of packaging). This minimum resistance imposes a minimum thickness of constituent material, and therefore a non-negligible, even high cost, as well as a mass which is also non-negligible (mass which adds nothing to the product consumed, but which must be transported , and mass of material that will sooner or later have to be destroyed without pollution or recycled,

often costly).

  The 'minimum holding' has therefore often become a minimum holding 'and insufficient, and it is not uncommon to see packaging of the type: box of milk or fruit juice for example, making the belly' under the load of objects placed on it, or when we want to use this type of box; te, the fact of holding it in the hand implying a pressure of the fingers on the walls, we do, after opening and almost without fail, ' squirt 'the product of

  uncontrolled way out of the package.

  In the same way, bottles of drinks (lemonade for example) with very thin polymer walls crush very easily on hand and the liquid spills

  as much on the table as in the glass.

  In addition, packaging designers cannot optimize the product outlet section after opening; the ideal would be to have a fast flow, as well in filling as in flow, but regular and easily controllable, whereas we have today most often, that is a flow almost regular but too weak, either a correct flow in quantity but very

  irregular and difficult to control.

  In addition, in terms of packaging creation, and to reduce the proportion (in terms of mass and cost in particular) of the packaging in relation to the packaged product, the designers are not only moving towards the thinnest possible packaging walls, but also to the largest possible individual containers (example: bottles of 1.5 to 2 liters or more instead of the classic 1 liter or 1/4 gallon bottles

  that have been used for a long time).

  In addition to the mass that the user must manually handle in the case of these large containers, and by the very fact in particular of the mass of the assembly, the use is delicate and, very frequently, the product contained (liquid, powdery product or in aggregates) flows even more irregularly and jerky and overflows or splashes its

  new container or the immediate environment.

  The greater the mass, the more the user squeezes the box, the can or the bottle so as not to escape it, and the more he tends to make the product 'squirt', in an uncontrolled manner. The air entering the packaging at that time, also irregularly, further increases the anarchic nature of the flow of the product. To try to alleviate these problems, more and more packaging designers are planning to use handles integrated or not in the packaging, but this is only a one-off help which is far from solving all the problems and which creates problems. '' others (more material and more cost for packaging, larger external volume, handle

  often placed too close to the neck, etc.).

  Furthermore, there are also devices for adjusting or closing the outlet opening of the packaging (for example: sliding plastic tab on certain milk cans for example) but they are generally external to the packaging, they are expensive and they do not really solve the problem of regularity of flow of the product to be consumed, they reduce this flow. In fact, they are generally only used

as shutters.

  The present invention aims to remedy very

  sensitive to all these drawbacks.

  To this end, the packaging concerned comprises at least one deflector situated inside the overall overall volume delimited by the packaging, this deflector making it possible, thanks to the phenomenon of internal turbulence of the product and of the air around its faces and therefore thanks to the hydrodynamic brake phenomenon which it constitutes during filling, but especially during the flow of the packaged product, of regulating the flow of the product whatever the filling flow rate or, in the flow phase for use of the product, the skillful or unskillful manner and the

  manual clamping pressure demonstrated by the user.

  This deflector is made either by the same material as that of the packaging, or by another material (polymer, metal, glass, paper-cardboard, textile, vegetable or complex material

  of these materials) and is preferably rigid or semi-rigid.

  It is placed inside the packaging and is then fixed by gluing, welding or stapling for example, or can be formed by a variation in the shape of the packaging (in this case it can also play the role of a diffuser thermal contributing to the faster warming up of a drink contained by it for example, or it can easily be combined with a handle which is also integrated in the packaging); it is advantageously located in one third of the volume of the packaging comprising the orifice or orifices for the flow of the product contained. It may consist of one or more internal transverse tongue (s) (rigid (s), semi-rigid (s) or flexible), or even a trellis, partially partitioning inside the volume of the packaging. In this case, the main passage area left free by the deflector thus formed will preferably be at the bottom when the packaging is tilted for product flow, so as not to 'trap' upstream of the deflector and thus be able to empty the packaging easily and completely; moreover, preferably at least one hole or a small passage section in the upper part will be provided so that the air can pass in the upper part of the deflector thus helping to regulate the filling or flow rate. The deflector may also consist of two tabs each linked to a wall of the package, these two walls facing each other, and the two tabs not touching leaving each other so a section of passage between them for the product to be sold. In all cases, the partition effect partially retains the product during its flow and almost automatically regulates this flow whatever the movements imprinted on the packaging by the user's hand.

  during the flow of the product.

  This or these tab (s) can or (can) constitute in its or (their) general shape a complete partition, it (s) will be (or will be) in this case provided (s) through holes of sufficient size to allow the flow of the product on the one hand and the necessary air inlets on the other hand. It (s) may or may also constitute an incomplete partition, but it (s) preferably constitutes (s) a filling greater than forty

  percent of the general internal section of the package.

  In the case where a deflector is linked to the two internal side walls of the packaging which face each other, or to 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 risks of bursting observed on the packages as soon as they are a little too thin or too weak taking into account the loads which they have to support and thus confers thus is a better safety to packaging, i.e. a possibility of reducing the thickness of

  identical safety packaging walls.

  It should be noted that packaging with an integrated handle generally has a narrowing of the section to the right of the area where the handle begins, but this is generally only five to thirty percent of the general section of the packaging and is not a sufficient deflector. The deflector device according to the invention can be generally planar, ribbed, or itself comprise several bosses, walls, fins or holes of various shapes (cut holes, conical holes, stamped or others). It will be adapted to the best of the flow of the product according to the general shape and size of the packaging and according to the nature of the packaged product. It should be noted that for containers for repetitive use (type: gourd, teapot, 'shaker', vinegar maker, etc.), partitioning devices of the type: sieve, perforated plate or fins which are placed in the inside the container, but they are designed and arranged in such a way that they act as a filter or stop for large solid particles (ice cubes, leaves, coffee grounds, etc.) or possibly a role of agitator or homogenization of the liquid contained, but they are not applied to packaging (generally for single use) and they do not play the role of deflector or deflector-stiffener as

that it is described here.

  In certain cases, the deflector could be of variable geometry or orientation in order to perfect the flow regulation as a function of the quantity of product remaining in the packaging, or possibly to constitute a second obturation, inside the same packaging which has the advantage of being able to close the packaging internally when the product is partially consumed, this by trapping less air above and therefore better preserving the initial quality of the product contained. In a preferred form of the invention, the deflector is made of a rigid or semi-rigid material and it constitutes at least one transverse stiffener of the packaging in an area close to the place where the user's hand grasps the packaging to dispose of the product. This stiffener thus contributes to the holding of the packaging not only thanks to its tensile strength, but also thanks to its compressive strength. To this end, it may be either sufficiently rigid in itself (sufficient thickness and resistance of its material), or rigidified by any suitable means (ribs, frames, etc.) and constitute

  thus a spacer or stiffening element of the packaging.

  The very big advantage of the deflector-stiffener is, in addition to the advantages of regularity of flow mentioned above, that it makes it possible to further thin the walls of the packaging concerned in a large proportion. Indeed, a packaging with very thin walls, or even a completely flexible packaging, can, thanks to the internal rigid deflector-stiffener, combine, on the one hand, sufficient resistance to the crushing pressure exerted by the hand of the user or by shocks and pressures due in particular to transport or storage, and on the other hand perfect

o10 regularity of flow.

  It is thus possible to produce packaging with very thinned walls, therefore very economical (walls a few hundredths of a millimeter thick instead of several tenths of a millimeter encountered most often at present), lighter and less polluting for the environment. Furthermore, in the case of boxes made of complex materials of the cardboard / metal / polymer type used either for the packaging of dairy products (milk, cream, etc.), or for fruit juices, there is a very often share the phenomenon of "belly" due to the own mass of the packaged product or of what is placed on the packaging, as mentioned above, or on the contrary a phenomenon of "hollow" to the right of the handle often reported to middle of the pack of six boxes (which limits the number of boxes per unit of grouping) and on the other hand a certain difficulty in opening these boxes without knife or scissors taking into account the thickness of the complex material cardboard / metal / polymer used , thickness precisely necessary and often insufficient to ensure the mechanical strength of the assembly. We also note an often anarchic exit of the product taking into account the pressure exerted by the hand on the central part or the "belly" of the box, pressure which contributes to make the product squirt

  irregularly out of the package.

  The present invention overcomes all these drawbacks in this case; Indeed, the fact of providing inside the box and, preferably linked to the internal walls, a semi-rigid deflector for example, makes it possible to avoid both the phenomenon of "belly" and that of "hollow" and therefore to thin the walls, therefore to facilitate the simply manual tearing (without cutting tool) of the folded part which then traditionally serves as a pouring spout, and this deflector also makes it possible, of course, to regulate in a large proportion the flow. This type of packaging then becomes almost

perfect in use.

  One can also also constitute almost completely flexible packaging provided only with one or more stiffeners which allows, in addition to the advantages of manual strength and regularity of flow added to a significant reduction in cost (very thin thickness for the part flexible), a significant reduction in the empty volume of the packaging, before initial filling or after use (saving in volume at the manufacturing level or at the level of disposal in household waste bins). Thus boxes, cans or bottles according to the invention may consist of a completely flexible envelope comprising one or more internal deflectors-stiffeners. In the case where the flexible material of the envelope is an elastomer, the advantages (unbreakability, automatic adaptation of the volume of the container to the residual volume of the product, etc.) are numerous but the cost of an elastomer generally being greater than the cost of '' a conventional thermoplastic material, it will be advantageous to design the packaging as being a reusable container (thickness of

sufficient walls, etc.).

  In the case of a flexible envelope (thermoplastic, textile or elastomeric) and in a preferred form of the invention, filling under pressure of the product in the box, the can or the bottle contributes to ensuring the mechanical strength of the assembly thanks to the tensile prestress exerted by the pressure in the flexible walls. In this case, the deflector (s) - stiffener (s) makes it possible in particular to prevent the product from spurting suddenly out of the packaging when the

spout or outlet.

  In order to mechanically reinforce the assembly, the internal stiffener (s) can (can) additionally provide longitudinal stiffening and not only transverse inside the packaging and in some cases, can combine internal deflector and stiffener, or even stiffening element of the packaging, external to the packaging

well said.

  In general, the deflector (stiffener or not) will be placed transversely to the main axis of the packaging and, as said above, preferably in the region of one third of the volume of the packaging on the outlet orifice side. However, depending on the nature of the product and the general shape of the packaging, the optimum inclination of the deflector will be sought, which will generally be between minus sixty degrees and plus sixty degrees relative to the plane perpendicular to the axis.

general packaging.

  Given the advantages provided by the invention, it will then be possible to go much more easily towards larger containers, which will further improve the ratio of

  mass or cost: packaged product / packaging.

  Furthermore, in the case of bottles containing wine for example, one or more deflectors may be provided which are integral with the bottle and come from molding for example (whether the bottle is made of glass or of polymer), deflector (s) which, in addition to the advantage of the regularity of flow or the rigidity and resistance of the whole of the bottle, gives (s) to the whole a partitioning effect suitable for preventing the wine from being too agitated during transportation; for wine indeed, the fact of calming or preventing the movements of liquid internal to the bottle, during transport for example, is extremely

  advantageous for the conservation of the quality of the wine.

  In any case, the invention will be well understood using

neck (2).

  Figure (2) shows in perspective a classic cardboard box with semi-rigid walls (la), equipped with a spout

integrated pourer (2a).

  FIG. 3 shows in section along a vertical plane passing through the axis AA a conventional polymer container capable of containing a liquid or a powder, a container generally obtained by extrusion blow molding and provided with an integrated handle (3). Note that zone (4) corresponds to a narrowing of the general section of the container perpendicular to the axis AA which does not exceed o10 thirty percent of said section and which, as such, does not really play a role. role of deflector to control

liquid flow.

  FIG. 4 is a perspective view of a conventional milk can provided with the folds (2b), one of which can serve as a pouring spout after unfolding and cutting or tearing, a box which here is full of milk and which shows a

  phenomenon of 'belly' in the central part of the walls (lb).

  FIG. 5 represents in perspective a can of engine oil with metallic walls here (lc), a can with a neck (2c) itself equipped with a flexible polymer tube (2d) intended to facilitate the pouring of the in the engine, but device which does not regulate the phenomenon of uncontrolled flow of oil due to the mass of oil laden above the neck during the engine oil pouring operation and due to air jolting

in the can.

  FIG. 6 represents a deflector (5) which may be metallic, plastic, cardboard or other, of generally planar shape, provided with two fins (6) intended to facilitate its fixing to

  the inside of the packaging it relates to.

  Figure 7 is a representation of a deflector of the type described in Figure 6 but comprising a rear fin (6a) for fixing instead of side fins and further comprising transverse ribs (5a) intended for both him give transverse rigidity and 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 a retraction of the deflector thanks to the small cords (6u) and (6v) the free end of which can be brought outside the packaging. Figure 8 is a representation of a deflector of the type described in Figure 6 but comprising a rear fin (6a) for fixing instead of side fins and having a hollow rib (7) playing a role both of stiffening deflector and air passage. This deflector further comprises

a hole of the stamped type (8).

  Figure 9 is a representation of a deflector of the type described in Figure 6 but having a main face (5c) provided with through holes (9) and (9a) for the

  product and holes (10) for the passage of air.

  FIG. 10 shows a deflector of the type described in FIG. 6 but comprising a main face (5d) curved along a radius (R) to give it better rigidity

  transverse and to facilitate the regularity of flow.

  FIG. 11 represents a deflector capable of being integrated into a packaging of circular section (bottle for example). Here it has a flat main face (5th) bordered by a circular fin (6b), the main face (5th) being truncated here along the straight line (11) in particular to allow passage to

liquid and air.

  FIG. 12 represents a polymer bottle (polyethylene, terephthalate, polyvinyl chloride, etc.) obtained here by the conventional extrusion-blowing process; in addition to its neck (2) provided with a conventional thread, the wall (1) has been shaped in the mold around two tongues which have thus made it possible to constitute the two deflectors (5f) and (5g) each with double wall, shaped so that they respectively leave the passage sections (11f and 11g) for the liquid in one direction, and for the air in the other direction during

evacuation of the liquid.

  Figures 12a and 12b show a bottle of the type described in Figure 12 but with deflectors inclined in the other direction relative to the plane perpendicular to

  the general axis of the bottle, and also with armatures-

  connections respectively (19f) for the deflector (5f) and (19g) for

the deflector (5g).

  The purpose of these reinforcement links coming from molding during the extrusion blow molding 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 armatures-connections being hollow and having a passage orifice 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 flow of

  outflow of cash during payment.

  FIG. 13 represents a perspective view of a fine and completely flexible bottle (here constituted by a transparent envelope) of the polyvinyl chloride type for example, flexible envelope which has been heat sealed (by means of a high frequency generator for example ) around a rigid assembly made of injected thermoplastic (polypropylene or polyethylene, rigid polyvinyl chloride, etc.) rigid assembly itself consisting of a rigid neck (2d) provided with an external thread to receive a screwable plastic plug , neck which is extended by three frames (2e, 2f, 2g) conforming to the general profile of the bottle and which rigidly connect lower two deflectors which are themselves rigid (5h and Si), these defectors 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 it is inclined for a pouring of liquid outside, deflectors each provided in the upper part (during the pouring operation) with an orifice (10h) for (5h) and (O10i) for (5i) for regulated passage of the air which enters of itself in the bottle when one

drains the liquid.

  The defectors (5h) and (Si) have a general truncated elliptical shape, the elliptical shape (5'h) or (5'i) being chosen to cooperate with the internal cylindrical shape of the flexible envelope (ld) and with l inclination of the deflectors with respect to the plane perpendicular to the general axis of the bottle. The flexible envelope (ld) is moreover welded or glued in a leaktight manner to the base of the neck (2d) and is fixed in a conventional manner (welding or bonding) inside a rigid bowl (2h) ( well-known base system). The advantages of such a bottle are numerous because the presence of the deflectors makes it possible to immediately view the manual holding area of the bottle, their rigidity makes it possible not to crush the bottle at the pressure of the hand, the deflectors ensure a flow regular and the more the bottle empties, the less it occupies volume,

  which facilitates its elimination after use.

  FIG. 14 shows another type of bottle here consisting of a rigid external reinforcement in injected thermoplastic, itself comprising eight vertical telescopic tie rods (14) integral with two octagonal rings (15a) and (15b) and with a rigid neck (2i) by means of the rigid truncated cone (16), rigid external reinforcement into which has been introduced an elastomeric envelope (le) (of the natural rubber, butadiene, neoprene, silicone, nitrile or other type), expandable envelope sealed manner (here bonding plus tightening by means of the inner ring (2j)), to the rigid neck (2i), and envelope itself sealed and which here comprises a flexible deflector (5j) of the same basic material as (the ), roughly flat deflector, truncated elliptical in shape, adhesive on the non-rectilinear part of its outline inside the wall (the)

  by vulcanization or by heat sealing for example).

  This bottle is obviously unbreakable for its leaktight part, and, the constituent material of (the) 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 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 trapped air above the liquid like what exists when you store a classic partially emptied bottle which generally greatly affects the quality of the remaining liquid (degasification, oxidation, etc.). Here in this case, as the liquid consumption and the reduction in volume of the envelope (le) can be easily compressed the telescopic holders (14) to adapt them to the strict length required . This elastic envelope solution is possible here without there being any squirt on the outside as soon as the bottle is opened thanks to the deflector (5d) which prevents any rapid movement of liquid, this guarantee being increased by a judicious choice of elasticity and mechanical strength

the envelope.

  The telescopic nature of the tie rods (14) can be replaced by a breakable or fragile nature of the rigid frame

  external, to reduce volume after use.

  Figure 15 is a sectional view of a glass wine bottle (1) provided with three deflectors (5p) (5q) (5r) coming from molding, the deflector (Sq) being shorter than the other two and arranged staggered in relation to them in order to create a 'chicane' effect capable of blocking the internal movements of the wine as much as possible during transport, without however

  prohibit the disposal of wine for consumption.

  FIGS. 15bis and 15ter respectively represent from the front and in section a polymer container provided with an integrated handle 3 and deflectors (5s) and (5t) coming directly from molding and leaving a longitudinal passage section (11r)

  for the product contained in the container and for the air.

  a pouring spout (2a) and a deflector (51) coming from molding.

  FIG. 17bis is a sectional view of a cardboard packaging box provided with a pouring spout (2a) and a deflector consisting of a rectangular cardboard sheet folded so as to constitute two faces (Sm) and ( 5n) and a triangle in profile view after fixing by gluing the tabs (6b) and (6c) on a

inside of the box.

  side tabs (6) Inside the container.

(12) in the container (13).

  The operator's hand (18) squeezes the box

  naturally in the central area near the deflector-

  stiffener (5) linked to the internal side walls of the box by means of heat-sealed tabs (6). This stiffening deflector (5) does not completely partition the interior of the box; it lasisse the orifices of passage (11s) and (11t) for the air and the liquid (12), and it plays a role at the same time of regulation of flow and

  increase in resistance of the box.
