Definitions

  • the present invention relates to the field of packaging allowing good preservation of the product it contains, in particular dairy product which can be kept cool, and more particularly to the field of containers without loseable parts.
  • the product can be solid at a refrigeration temperature, semi-liquid, liquid or in a viscous state, possibly in a form which facilitates its recovery/distribution, the product can optionally be consumed using a spoon for example.
  • Containers having an integrated closure system of the type not separated from the side wall, are known.
  • the document US 6164488 describes a cup made of paper or similar material that includes a flexible panel formed in its side wall. The flexible panel is folded down to close above the cup, leaving a narrow opening for drinking.
  • these designs rely on creating a seal between the flexible panel and the internal wall against which it abuts.
  • the document GB 2269811 provides a similar arrangement for closing a container with an integrated closure portion on one side of the side wall.
  • a hinge effect makes it possible to pass the closing part (thinner than the stop region, opposite) from an externally convex conformation, corresponding to the open state of the container, to an externally convex conformation. concave corresponding to a state joined against a complementary interior face of the side wall.
  • This type of container must, however, be made of plastic and is also relatively complex, in particular to obtain a bistable character of the closure part, which limits the interest of this solution.
  • the document US 5352466 describes a coffee package whose easy opening system has a pair of grip tabs, capable of being pulled to separate opposite walls connected together by bellows, and thus allow the package to be opened with a spacing which remains limited.
  • the document WO 01/26980 describes another configuration in which a plurality of tabs are hingedly attached to the upper edge of the side wall of the container/cup.
  • the legs are each generally trapezoidal in shape with respective hook extensions that engage with each other and around a straw when the legs are bent flush with the top edge of the cup.
  • the document DE1052305 B describes a container also provided with a complex closure to produce, this container making it possible to contain a liquid such as milk.
  • closing cups of this type can prove problematic, for example, in the fast food sector where a large number of drinks are served in a relatively short period of time, or even in the field of high-speed packaging of products, requiring an easy closing operation. This is for example the case for filled containers that must be immediately refrigerated and transported to marketing destinations. It would also be desirable to improve the reliability of the seal (well airtight) in order to ensure that the contents of the container remain intact, the seal having to withstand transport constraints (vibrations in particular).
  • the two protrusions result for example from a cut and project upwards before and after tubular shaping of the side wall, the side wall and the protrusions being formed from a sheet material, preferably a same room.
  • the sheet material may be a material based on paper or cardboard, for example a laminate comprising at least one layer of paper or cardboard and possibly several layers of metal and/or plastic and/or other materials improving properties.
  • barrier Sheet material may be in the form of reels or pre-cut units.
  • the material to constitute the bottom can be identical to that to form the side wall and protrusions. More generally, we understand that the two protrusions cannot be lost. After emptying the container, the consumer can throw it away in one piece. This type of container is thus well suited for nomadic uses, being able to be transported in a backpack or various containers, possibly thermally insulated for the case of a fresh product contained in the container, limiting the risk of losing a lid or other loseable part.
  • the container has an opening configuration (in a vertically erect state), in which a first protrusion of the two protrusions remains projecting upwardly, away from the bottom, while all or part of the other or second protrusion is turned over or folded down on an exterior face of the side wall, downwards.
  • the container can therefore be placed by its base on store shelves.
  • one of the protrusions can be used to form rows of containers supported by a support rod passing through an orifice included in the protrusion, or to assemble containers in a group held together by a collar, cord or fixing element common passing through this type of orifice.
  • the bottom and the opening can each extend along a respective transverse plane, preferably perpendicular to the side wall.
  • the opening thus forms access to the interior volume from above, which allows for example to hold the container vertically by hand when consuming the product (if necessary using a spoon or other utensil for collecting the product). It is understood that the container can minimize the parts to be thrown away and keeps the gripping areas away from the internal surfaces in contact with the product (surfaces located under the sealing zone, below the level of the opening in practice).
  • the expression “the side wall extending upward (vertically) from the bottom” should be understood in the broad sense, that is, it is not necessary that the side wall or cylindrical: it must more generally be understood that the side wall has a generally vertical extension (the wall can be flared upwards having a geometry which varies according to the height level of the wall).
  • tubular must be understood in the broad sense when it describes the side wall, that is to say that it is not necessary that the side wall have a symmetry of revolution: on the contrary, a tubular wall can designate here a wall which extends from a narrower annular end and/or having a first determined shape to another wider annular end and/or having a second geometric shape different from the first geometric shape.
  • the two input portions are offset from each other. It is understood that the container is of the quick-opening type.
  • a simple gesture is enough to obtain the opening, without tools.
  • carrying out the movement of separating the gripping portions can be conditioned on unlocking or the removal of a security element (removable and/or peelable).
  • At least one of the two protrusions is a protrusion having or consisting of an outward flap.
  • it is a folding (fully folding) outward protrusion.
  • a single part can include the side wall and each of the protrusions.
  • the folding protrusion is of the folding type between a position projecting upwards relative to the level of the opening and a folded position below the level of the opening.
  • the foldable protrusion may include a region forming a peelable attachment layer for forming the sealing zone. Such a region can extend for example intermediately between the upper end of the side wall and the gripping portion provided in the folding protrusion.
  • the present invention it is possible to provide a container which can be aesthetically pleasing, quick to open and capable of effectively preserving the contents/product, where appropriate for a fresh product to be consumed before warming to room temperature. It is also allowed great flexibility in the geometry of the protrusions which allow hermetic sealing.
  • all or part of the sealing area is part of a folded end of the container in a modified closed configuration. It can be expected that the two protrusions are in a folded state on the same lateral side of the container in the modified closed configuration. It is understood that this modification can consist of a simple folding making it possible to limit the height of the container, which is advantageous for example during transport or when presenting the container on store shelves or shelves.
  • a fastening element may be provided, for example an adhesive pad, making it possible to maintain the modified closed configuration.
  • the adhesive pad is for example located on one fixing side and stuck laterally both on the side wall and on an end part of at least one of the gripping portions (after having folded down the two protrusions on the holding side /fixation).
  • the container can be produced with a minimum of parts that can be recycled (for example paper or cardboard) and superior sealing is allowed, at the stage of a final stage of production of the container which is easy to implement, without hindrance in relation to the product which has been poured into the interior volume (pouring of product without reaching or exceeding the level of the opening located under the sealing zone).
  • the first end of the side wall is shaped in an oval manner by attaching, from the inside, to an external edge of the oval-shaped bottom.
  • the part is cut and the side wall is shaped so that it has an increasing perimeter as we move away from the bottom.
  • the fixing between the two protrusions is carried out by forming the sealing zone transversely to a central axis of the side wall.
  • a sealing zone can for example extend between two opposite ends which, in the closed configuration of the container and in a vertically erect state of the side wall, are spaced horizontally from one another by a greater determined distance to the largest characteristic dimension of the bottom (which extends horizontally).
  • the container 10 comprises a bottom wall 1 and is adapted to delimit an interior volume V above this bottom wall 1, by forming a side wall 2 connected (tightly) to the bottom wall 1.
  • the container has an opening O, here a single opening which can be substantially as wide as the bottom 1a of the container 10 (at least as wide as a smaller dimension D2 of the bottom 1a, if necessary).
  • Product P for example a food product, can be poured into the interior volume V via such an opening O, before a sealing step which is carried out by bringing together two protrusions 2a, 2b which are typically integrally formed with the side wall 2.
  • the sealing obtained by fixing the two protrusions 2a, 2b against each other, makes it possible to obtain the closed state of the container 10.
  • the top or top of this container 10 is thus of the closed type without a separate cover, as visible on the figures 2 And 3 .
  • the container 10 can be made from two parts each made of a sheet material: one to constitute the bottom wall 1, the other to constitute the side wall 2.
  • the walls 1 and 2 can be made from the same part obtained by cutting a sheet material. In other options, a larger number of coins can be used in order to obtain container 10.
  • the fold LP is continuously curved and the bottom 1a may have a non-round section, for example oval with a large diameter D1 greater than the small diameter D2.
  • the D2:D1 ratio can be less than or equal to 0.9.
  • the external face of the tubular edge 1b can be fixed against a lower annular fixing zone of the side wall 2, called in the following first fixing part FP1.
  • the lower end 10a of the container 10 can optionally extend lower than the bottom 1a.
  • the top or upper end 10b of the container 10 may, in the closed configuration, include ends of the two protrusions 2a, 2b.
  • the upper end 10b may include only one of the protrusions 2a, 2b, with in this case for example a lateral arrangement of the gripping portion associated with the protrusion of lower height.
  • the side wall 2 is shaped like a tube, around a central axis is allowed here to produce the side wall 2 and the two protrusions 2a, 2b by a single part 200, of the type illustrated on the figure 5 or similar.
  • a cut of a laminated or sheet material can for example be carried out to obtain the part 200, which is initially plane or flat before being shaped.
  • the part 200 is flexible, based on a deformable material and for example of the cellulosic type.
  • This cellulosic material can optionally form more than 90 or 95% of the average thickness of the container 10 (thickness which can correspond to the thickness of the side wall 2).
  • the part 200 is laterally cut so as to include two side edges B1, B2.
  • the two lateral edges B1, B2 diverge from one another as one approaches a zone or folding line of the folding protrusion 2b. This makes it possible to enlarge the opening O for better accessibility of the product P.
  • a folding line is provided which is obtained by the addition of two deformation lines or initial striations S14a and S14b making it possible to obtain a folding line 14 of the type illustrated on the figure 1 .
  • the lateral cut of the part 200 makes it possible to obtain an increasing profile of the perimeter of the side wall 2 (formed by this part 200), as one moves away from the bottom. 1a.
  • the section of the container 10 is progressively larger.
  • the first fixing part FP1 makes it possible to stiffen a first (lower) end of the side wall 2, by fixing it against the folded external annular face or edge 1b of the bottom wall 1. In this way the first end of the side wall 2 is stabilized and remains substantially constant/not deformed in section, without variation in geometry when passing from the closed configuration to the opening configuration of the container 10. Conversely, the second (top) end of the side wall 2 constitutes a annular end 20 of deformable section.
  • the second fixing part FP2 which can be extended following a longitudinal extension as illustrated in the Figure 5 , makes it possible to maintain the tubular conformation of the side wall 2 while allowing a spacing between the two protrusions 2a, 2b which is accompanied by a rounding of the top of the side wall 2, in top view.
  • the fixing/overlapping width corresponding to the second fixing part FP2 may be less than or equal to 10 mm, for example between 3 and 8 mm.
  • the second fixing part FP2 defines an exterior fixing surface which is covered by a corresponding interior zone (on the rear side of the part 200 as illustrated in the Figure 5 , so that the side edge B1 and the associated side margin forming the fixing part FP2 will be hidden by the other side margin including the side edge B2.
  • These side margins can be fixed one on top of the other, forming a liquid-tight barrier, for example by depositing an additional layer of coating, after fixing with overlap of edge B1 by edge B2.
  • the cut sheet or part 200 thus has an overlapping region, with an overlap of the opposite edges B1, B2 of the part 200.
  • the bottom wall 1 can possibly also already be joined from the inside against the first fixing part FP1 during the shaping of the side wall 2.
  • a single piece 200 cut from a sheet can make it possible to produce the side wall 2, which extends from a lower edge 25 to an irregular upper cutting edge 26. While the lower edge 25 can make it possible to define an annular section corresponding to a base plane of the container 10 at its lower end 10a, in the tubular conformation of the part 200, the upper cutting edge 26 includes two or three vertices T1, T2, T3 which may be part of input portions 4, 5.
  • junction line J at the level of one of the protrusions 2a, 2b, for example a longitudinal junction line passing through one of the gripping portions (here the gripping portion 5), makes it possible to extend the length of the fixing area.
  • this junction line J corresponds to a maximum length of the side wall 2. This makes the container 10 more robust.
  • One of the two protrusions 2a, 2b can be obtained by joining two protrusions 11, 12 initially formed in the part 200 at two opposite lateral ends, by overlapping and corresponding/coinciding, possibly at the same height level, the summits T2 and T3.
  • the grip portion 4 is entirely included in the protrusion 12 and forms the vertex T3 of the part 200 before assembly, the vertex T2 not being as high as the vertex T3.
  • the junction line J can stop before the input portion 4 or be offset relative to this input portion 4.
  • junction line J can be provided and the examples shown are only given by way of illustration. Although two rectilinear edges B1, B2 are shown, wavy cutouts or with one or more hollowed-out regions may possibly be provided, without this preventing the side wall 2 from being shaped in a tubular manner.
  • the part of the container 10 constituted by the part 200 may be devoid of a zone folded at 90° or more along a line or horizontal hinge zone (parallel to the bottom 1a).
  • the container 10 can be adapted for various capacities of product P, which can be a fresh food product, for example a dairy product (yogurt-based depending on one option) and/or a compote, where appropriate a mixture of a solid product (such as Muesli, cereals, chocolate chips, etc.) in a fluid or semi-fluid base product.
  • product P can be semi-liquid, solid, or contain at least partly a liquid.
  • the product P is for example well suited to being consumed using a spoon and has the ability to fit the interior face F of the side wall 2.
  • the interior face F of the side wall 2 and the upper face of the bottom wall 1 are contact faces made for example of a material and/or a film having low water permeability and approved for food contact.
  • the material may be identical to that of the interior face F, with the possible exception of an optional layer used to obtain the sealing zone Z or Z1, Z2.
  • a material and/or a covering film can be provided which optionally is not flammable.
  • the oval shape of the bottom 1a can facilitate the formation of opposite panels 24, 25 constituting two main sub-parts of the side wall 2.
  • the figure 2 shows, in front view, one of these panels 24 (front view in relation to the sealing zone or sealing plane SP).
  • these panels 24, 25 are connected to each other via narrow sub-parts folded/curved each inwards and extending vertically between the bottom wall 1 and the level of the opening O.
  • each narrow sub-part (narrow compared to the width of the panels 24, 25) has a geometric shape which is substantially triangular or frustoconical widening towards the bottom 1a. This shape is seen in side view in relation to the sealing plane SP.
  • the two opposite narrow sub-parts are complementary to the panels 24, 25 and therefore complete the panels 24, 25 in the side wall 2.

  • the level H1 of filling with product P can vary slightly downwards by going from a closed state of the container 10 to an open state.
  • the sealing zone Z can be substantially planar (with an ascending/vertical component), by defining a sealing plane SP, which typically implies, in this example, a coplanar extension of the protrusions 2a and 2b, at least for part.
  • This has the effect of making the two main panels 24, 25 converge towards each other. in the closed configuration of the container 10, so that the folding line 14 separating the folding protrusion 2b from the first panel 24 can be adjacent to the second panel 25 in its connection zone with the protrusion 2a which extends this panel 25 upwards.
  • the tightening effect between the panels 24, 25 pushes the product P upwards (this product P having a fluid or semi-fluid character), to a level H1 which is greater than the level H1' shown to the right of the Figure 7 .
  • the interior face F1 of the protrusion 2a may include a self-adhesive layer or a contact fixing part, above the annular end 20 where the fold line 14 is defined.
  • this layer is broken down into two regions 21, 22 which rise towards the upper end 10b, joining in a junction part close to the gripping portion 5.
  • the fixing parts are distributed differently on the interior faces F1, F2 of the protrusions 2a, 2b. More generally, we understand that the arrangement of the sealing zone can be planned so that a region thereof is close to at least one of the gripping portions 4, 5.
  • the sealing zone Z1, Z2 extends entirely above the annular end 20 where the fold line 14 is defined.
  • the sealing zone Z1, Z2 here has an inverted “V” shape being broken down into a first sealing sub-zone Z1 and a second sealing zone which joins the first sealing sub-zone Z2 for continuity of the sealed connection contact made by the sealing zone Z1, Z2.
  • the sealing zone can have any type of geometry to close (here from the top) the opening O. It can be advantageous for the sealing zone Z to locally have at least one upper cussing zone (intermediate between two parts descending sealing) and ends 3a, 3b approaching as close as possible to the upper level of the product P, for example by reaching the level of the opening O. It is understood that, in all cases, the sealing zone Z or Z1 , Z2 extends transversely to a central axis X of the tubular side wall 2.
  • the sealing zone Z or Z1, Z2 extends continuously in the closed configuration between the two opposite ends 3a, 3b which are spaced horizontally from one another by a determined distance D3 greater than the largest characteristic dimension D1 of the bottom 1, as illustrated for example on the figure 2 .
  • a joining edge of the side wall 2 present on the external face of this side wall 2 is covered with a plastic coating, for example deposited in the form of a jet/spray. This constitutes protection of the overlapping strip constituting the edge-to-edge junction J of the side wall 2 as shaped in a tubular manner, knowing that this junction J is located in a deformable part of the container 10.
  • the material of the side wall 2 and the protrusions 2a, 2b is compatible with the formation of streaks, obtained for example by localized crushing of the fibrous and/or cellulose material integrated into the thickness of this material.
  • One or more sets of grooves S14a, S14b, FL1, FL2, isolated groove or reliefs for assisting deformation and/or folding can facilitate obtaining, in the upper part of the side wall 2, a suitable geometry to the consumption of product P.
  • grooves can be provided which each constitute a predetermined folding line.
  • the grooves are provided exclusively in one of the two sub-parts or panels constituting the two opposite main faces of the container 10 in its closed configuration.
  • An asymmetrical character of the container 10 can thus be obtained by placing horizontal grooves exclusively on the panel 24 connected to the protrusion 2b to be folded down to free and widen the opening O.
  • the groove S14 placed in the plane of the opening O (this streak which may result from the combination of several streaks, for example the two streaks S14a, S14b shown on the figure 5 ) thus forms the fold line 14.
  • the groove S14 can have a length substantially equal to half a perimeter of the annular end 20 bordering the opening O.
  • any other local deformation or physicochemical treatment step can be used to form a folding line making it possible to form a folding protrusion 2b following a predetermined folding.
  • folding lines parallel to the folding line 14, already present in the closed configuration of the container 10 are optionally formed using ridges FL1 which can be distributed on the folding protrusion 2b, while the other protrusion 2a may be smooth and free of fold lines. It is typically expected that these fold lines, here formed by ridges spaced at least 3 mm apart from each other, are shorter than the fold line 14, as visible in front view in the closed configuration.
  • the folding of the flap formed by the protrusion 2b is done by quickly tilting the corresponding gripping/actuation portion (grasping portion 4 of the Figure 6 ) down.
  • the reversal of orientation of the gripping portion 4 can be carried out before the protrusion 2b is folded back more than 45° around the line of folding 14, which is allowed using the small folding lines FL1.
  • the end of the stroke can then consist of pulling the protrusion 2b downwards while continuing to fold and fold outwards the lowest part of the protrusion 2b, until obtaining the completely folded position of the type visible on the figure 1 , typically without significant widening of the opening O.
  • the grooves FL2 can extend vertically on either side of the folding line 14 and contribute to assisting/helping the end of the stroke in the folding movement of the protrusion 2b, for example by avoiding the formation of an angle (s) blocking the movement of the flap.
  • these FL2 grooves (here at least five or six in number) can provide a guiding effect, in order to round the side wall 2 more easily and avoiding the formation of a pronounced angle or V-shaped profile which would be visible in top view.
  • the rounding of the fold line 14 can then be close or identical to the illustration of the figure 1 , avoiding forming a pronounced angle near the junction line J.
  • a smooth surface is obtained which can make it possible to produce a print. More generally, any type of marking (possibly embossing) can be made on the surface without a fold line, such a surface being favorable to the visibility of information, for example information about the product P contained in the interior volume. V.
  • the flattened appearance of the panel 25 also makes reading such information easy for a consumer observing the container 10 in a stored state on a shelf in a store or in a similar presentation situation.
  • FIGS. 9A and 9B show the way in which the container 10 can be manipulated, going from a compact configuration to a deployed configuration, then to an open configuration allowing the consumption of the product P contained in the interior volume V of the side wall 2.
  • Fold lines FL1 can also be provided in this embodiment to facilitate the folding of the protrusion 2b with an arcuate conformation (curved outwards) compatible with a wide opening O of the container 10. This is an optional embodiment .

  • this configuration limits the height of the container 10.
  • all or part of the sealing zone can be mobile in the state sealed with the two protrusions 2a, 2b, in particular when it is desired to minimize the height of the container 10 during transport and/or storage stages.
  • the container 10 has a movable end (by pivoting or folding along the line 14') so that it can be folded down into a modified closed configuration.
  • the user can release and/or grasp the movable end of the container 10 to straighten it, in order to move from the modified closed configuration to the closed configuration as shown on the figure 2 , 3 And 6 .
  • the gripping portions 4, 5 are folded down with the protrusions 2a, 2b and thus protected from accidental opening manipulation.
  • a fastening element may be provided, for example an adhesive pad 60, making it possible to maintain the modified closed configuration.
  • the adhesive pad 60 is for example located on one fixing side and stuck laterally both on the side wall 2 and on an end part of the container including at least one of the gripping portions, here the gripping portion 5 of the protrusion 2a.

  • these gripping portions 4 and 5 extend upwards relative to the rest of the corresponding protrusions. 2a and 2b, which corresponds to the deployed closed configuration. More generally, we understand that in the closed configuration deployed/allowing the opening operation, we find the folding protrusion 2b in a position projecting upwards, from the folding line 14.
  • the folding protrusion 2b can be folded outwards and come into contact with part of the adhesive face of the pad 60. Indeed, as this part of the adhesive face 61 has been turned outwards, it constitutes a support for fixing/maintaining the protrusion 2b in the folded position. In the example illustrated, the gripping portion 4 comes into contact with the adhesive face 61. It should be emphasized that this embodiment avoids completely detaching the pad 60, so that it does not constitute a loose and loseable part. In fact, there remains a fixed part 62, belonging to the pellet 60, which is not detached from the side wall 2.
  • the bonding of the pellet 60 can be carried out with two different adhesion forces: stronger for the part 62 which is fixed and weaker for the part 61 which is peelable.
  • the pad 60 is made in one piece and may consist of a multilayer sheet material, preferably without a metal layer.
  • Obtaining a wide opening O is typically obtained in the same way already described with reference for example to the Figure 7 .
  • Inward pressure by the user on the side wall 2, on either side of the folded protrusion 2b, makes it possible to enlarge the section of the opening O without raising the flap formed by the protrusion 2b .
  • There consumption of the product P can then be done easily, for example by a utensil U such as a spoon, a fork or any other suitable utensil(s).
  • the gripping portions 4, 5 are asymmetrical and one of them has an orifice 50, 50' facilitating the support of the container in store shelves or departments.
  • the gripping portions 4, 5 are typically integrated into the protrusions 2a, 2b, without folding or change of direction, by projecting upwards/extending higher respectively with respect to an edge facing the other protrusion 2a or 2b.
  • the upper end of the container 10 can then include these two gripping portions 4, 5 in the closed state.
  • the gripping portions 4, 5 can be aligned in a plane SP which includes the sealing zone Z; Z1, Z2.
  • the gripping portions 4, 5 can be provided for different shapes, symmetrical or non-symmetrical, can be provided for the gripping portions 4, 5.

  • the protrusions 2a, 2b can each - or at least one of them - taper upwards in the closed configuration by being delimited by two delimiting edges 41, 42 or 51, 52. It is understood that the portion input 4, 5 can correspond to a region of the protrusion towards which the two delimiting edges 41, 42 or respectively 51, 52 converge.
  • Part 200 shown on the figure 5 can be obtained after a few steps including one or more cutting steps and processing steps making it possible to define the folding line 14 for folding the second folding protrusion 2b as well as other folding lines and/or weakening of material.
  • a cutting step 51 is carried out, optionally at high speed, by a UC cutting tool in order to obtain pieces of sheet, here in a trapezoidal shape. It is understood that the part 200 can result from a cut made in one go or possibly broken down into an initial cut and a secondary cut of a piece of MF sheet material. In the example illustrated, for simplification, the protrusions have been omitted in the cutting step 51. However, it may be preferred to produce the outline of the two protrusions 2a, 2b from this initial cut made in step 51.
  • this cut makes it possible to define the final lower edge 25, the two sides or lateral edges B1, B2 (in a general shape which is then close to a trapezoid) and also the two protrusions 2a, 2b.
  • side edges B1, B2 are provided which move away from each other as we move away from the lower edge 25 and as we approach the level of the opening O
  • This type of geometry of the side edges B1, B2 is advantageous for benefiting from an increased deformation effect at the level of the opening O.
  • Each part 200 is then subjected to a series of treatments for shaping. For example, we can directly heat the strip portions formed in the lateral margins of each piece (margins including the edges B1, B2) and shape the part 200 into a sleeve. A rotating impression with frustoconical geometry can form a support so that the part 200 is wrapped around this imprint, so that they form a sleeve due to the overlap of the margins or side strip portions.
