Definitions
- the present invention relates to the field of packaging for good preservation of the product it contains, in particular dairy product that can be kept cool, and more particularly the field of containers with no lost part.
- the product can be solid at refrigeration temperature, semi-liquid, liquid or in a viscous state, optionally in a form which facilitates its recovery / distribution, the product can optionally be consumed by means of a spoon for example.
- Containers having an integrated closure system of the type not separated from the side wall, are known.
- US 6164488 discloses a cup made of paper or similar material which includes a flexible panel formed in its side wall. The flexible panel is folded down to close over the cup, leaving a narrow passage opening for drinking.
- these designs rely on creating a seal between the flexible panel and the inner wall it abuts.
- GB 2269811 provides a similar arrangement for closing a container with an integrated closure part on one side of the side wall.
- a hinge effect makes it possible to change the closure part (thinner than the stop region, opposite) from an externally convex conformation, corresponding to the open state of the container, to an externally conformation concave corresponding to a state attached against a complementary inner 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 nature of the closure part, which limits the value of this solution.
- 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 which engage each other and around a straw when the legs are folded flush with the top edge of the cup.
- 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 be problematic, for example, in the field of fast food restaurants where a large number of drinks are served in a relatively short period of time, or in the field of packaging at high speed. of products, requiring an easy closing operation. This is the case, for example, for containers that are filled and have to be immediately refrigerated and transported to marketing destinations. It would also be desirable W Q reliability of the seal (well hermetic) in order to be ÎPSJJ 1 ; 3 ⁇ 4 iu of the container remains intact, the seal having to withstand the constraints of transport (vibrations in particular).
- a container intended for packaging a product comprising: a bottom, a side wall delimiting an interior volume, the side wall extending upwards ( vertically / ascending) from the bottom to an annular end defining an opening for access to the interior volume; the container having a closed configuration and further comprising two distinct protrusions (or two ears) to obtain the closed configuration, in which the two protrusions are (in particular simultaneously):
- the container having two gripping portions, distributed over the two protrusions, each of the two gripping portions being arranged beyond the sealing area.
- the container can be simple and the sealing robust.
- a spoon, fork, straw (if the product is sufficiently liquid), chopsticks, or tongs can be used to retrieve the product through the opening.
- This design is also well suited for the use of paper or cardboard or laminates comprising a layer of paper or cardboard, easy to recycle.
- Both protrusions result for example from a cutout and protrude upward before and after tubular shaping of the side wall, the side wall and the protrusions being formed from a sheet material, preferably one. same room.
- the sheet material can be a material based on paper or cardboard, for example a laminate comprising at least one layer of paper or caton and optionally one more layers of metal and / or plastic and / or other materials improving properties.
- barrier The sheet material can be in the form of coils or pre-cut units.
- the material for constituting the bottom can be identical to that for forming the side wall and the protrusions. More generally, it is understood that the two protrusions are captive. After emptying the container, the consumer can throw it away in one piece.
- the container has an open configuration (in a vertically upright 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 or folded over an outer face of the side wall, down.
- the container can therefore be placed by its base on store shelves.
- one of the protrusions can be used to form rows of receptacles supported by a support rod passing through an orifice included in the protrusion, or to assemble receptacles into a group held together by a collar, cord or fixing element. common crossing 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 an access to the interior volume from above, which makes it possible, for example, to hold the container in the hand vertically 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 discarded and keeps the gripping zones away from the internal surfaces of contact with the product (surfaces located under the sealing zone, below the level of the opening in practice).
- the expression “the side wall extending upwardly (vertically) from the bottom” is to be understood broadly, i.e. it is not necessary that the side wall either cylindrical: it should 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 level of height of the wall).
- tubular should be understood in the broad sense when it qualifies the side wall, that is to say that it is not necessary for the side wall to have a symmetry of revolution: on the contrary, a tubular wall can denote 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 one another.
- the container is of the quick opening type.
- a simple gesture is enough to obtain the opening, without tools.
- carrying out the gesture of separating the gripping portions can be conditioned on unlocking or removing a security element (removable and / or peelable).
- At least one of the two protrusions is a protrusion having or consisting of a flap towards the outside.
- it is a folding protrusion (fully folding) outwards.
- the folding protrusion is of the folding type between a protruding position Q ?, w, t 2! l ! .U! ) relative to the level of the opening and a position of the level of the opening.
- the hinged protrusion may include a region forming a peelable securing layer for forming the seal area. Such a region may for example extend intermediate between the upper end of the side wall and the gripping portion provided in the folding protrusion.
- the side wall and the protrusions are made of sheet materials based on paper or cardboard, for example laminates comprising at least one layer of paper or cardboard and optionally one several layers of metal and / or plastic and / or other materials improving barrier properties.
- the sheet material can be in the form of coils or pre-cut units.
- the side wall is shaped as a sleeve, so that the default positions of the two protrusions are upward extension positions with a horizontal distance between them.
- each of the two protrusions has a base connected to the side wall, the two bases forming two halves of a periphery surrounding the opening of the container.
- one of the two protrusions preferably only one of the two protrusions, is connected to the side wall by a predetermined fold line, a groove in the part (part forming the side wall and the two protrusions) making it possible to define the fold line predetermined.
- the two protrusions are integral with the side wall.
- the side wall and the two protrusions are made in one piece, preferably one in the form of a cutout of a laminate or sheet material.
- the part to form the side wall and the protrusions is based on a deformable material including a cellulosic material and shaped into a sleeve by overlapping two strip portions.
- the two strip portions each include a side edge of the side wall, and are attached to each other to form a liquid-tight barrier.
- a gas-tight barrier effect can be achieved, in an annular / tubular retaining junction area / line of the side wall), in particular by means of an external coating on an area of overlap of the two portions of tape.
- wo 5S 2 .3 ⁇ 4 iWS3 ⁇ 4.ne of the two protrusions is a folding protrusion ⁇ .I /? 3 ⁇ 491 ° 95 ?. 256
- the opening is partly delimited by a fold line allowing the folding protrusion to be folded down, preferably so that the folding protrusion extends downwards from the fold line.
- the folding protrusion is movable between a first position to close the container and a second position; this protrusion is typically butted against the inner face of the other of the two protrusions in the first position (the folding protrusion extending upward from a fold line parallel to the bottom), while in a second position the container is opened thanks to the folding of the folding protrusion, this folding being carried out outwardly opposite the other protrusion (which preferably remains projecting upwards).

- these gripping portions 4 and 5 W Q ⁇ .VJlJ 'brs the top over the rest of the protrusions which corresponds to the deployed closed configuration. More generally, it is understood that in the closed configuration deployed / allowing the opening operation, we find the folding protrusion 2b in a position projecting upwards, from the fold line 14.
- the folding protrusion 2b may be folded outward and come into contact with a part of the adhesive face of the patch 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 down position. In the example illustrated, the gripping portion 4 comes into contact against the adhesive face 61. It should be noted that this embodiment avoids completely detaching the pellet 60, so that it does not constitute a loose and lost part. Indeed there remains a fixed part 62, belonging to the pellet 60, which is not detached from the side wall 2.
- the gluing of the patch 60 can be achieved with two different adhesion strengths: stronger for the part 62 which is fixed and weaker for the part 61 which is peelable.
- the pellet 60 is made in one piece and may consist of a multi-layered sheet material, preferably without a metallic layer.
- Obtaining a large opening O is typically obtained in the same way already described with reference, for example, to FIG. 7. Pressure inwards by the user on the side wall 2, on either side. of the folded protrusion 2b, allows the section of the opening O to be enlarged without however raising the flap formed by the protrusion 2b.
- the 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 shelves or store shelves.
- the gripping portions 4, 5 are typically integrated into the protrusions 2a, 2b, without bending or changing direction, projecting upward / extending higher respectively from an opposite edge. other protrusion 2a or 2b.
- the upper end of the container 10 can then include these two gripped 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 may be provided for different shapes, symmetrical or non-symmetrical, may be provided for the gripping portions 4, 5.
- at least one of the gripping portions 4, 5 may not reach the upper end of the container 10 in the state. closed and / or may form a tab placed externally to the sealing plane SP.
- Each grip portion may extend, vertically or at an angle, from a baseline to a free upper end.
- Each base line of the input portion 4 or 5 is then aligned with a delimiting edge of the other protrusion, the delimiting edge of which exceeds the considered input portion 4 or 5.
- that line 2 ⁇ m / ij ( ⁇ 'elongated and exceeds 25 or 30 mm for each of the ⁇ Ji3 ⁇ 49?. 2 / ⁇ , 3 ⁇ 4 ⁇ e which makes these protrusions robust and easy to grip.
- They are optionally made from laminated cardboard or material cellulosic like sufficiently compressed and / or protected by a coating to be resistant to tearing, so that they are in practice impossible to tear accidentally.
- the protrusions 2a, 2b may each - or at least one of them narrow upward in the closed configuration being delimited by two delimiting edges 41, 42 or 51, 52. It will be understood that the gripping portion 4, 5 may correspond to a region of the protrusion towards which the two delimiting edges 41, 42 or respectively 51, 52 converge.
- the part 200 illustrated in Figure 5 can be obtained after a few steps including one or more cutting steps and processing steps to define the fold line 14 to fold the second folding protrusion 2b as well as other fold lines and / or material weakening.
- a cutting step 51 is carried out, optionally at high speed, by a cutting tool UC in order to obtain pieces of sheet, here of trapezoidal shape. It is understood that the part 200 may result from a cut made all at once or possibly decomposing into an initial cut and a secondary cut of a piece of MF sheet material. In the example shown, for simplicity, the protrusions have been omitted in step 51 of cutting. However, it may be preferred to make 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.
- the part 200 is therefore obtained.
- lateral edges B1, B2 are provided which move away from each other as one moves away from the lower edge 25 and when approaching the level of the opening O.
- This type of geometry of the lateral edges B1, B2 is advantageous in order to benefit 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, it is possible to directly heat the portions of strip formed in the lateral margins of each piece (margins including the edges B1, B2) and to shape the part 200 into a sleeve.
- a rotating indentation with frustoconical geometry can form a support so that the part 200 is wrapped around this indentation, so that they form a sleeve due to the overlapping of the margins or portions of the strip w Q * ? 5i3 ⁇ 4il ⁇ ⁇ î ⁇ 2tte shaping step 52 can optionally c £ G! / i5? 9J ° $ 3 ⁇ 423 ⁇ 4ge and winding of the part 200.
- an edge protection step 53 is performed in order to cover the edge or edges B1, B2, which intervene to form the junction part J, with a coating which improves the liquid tightness.
- the junction part J of the side wall 2 is permanently sealed (taking into account the duration of transport / storage in, store and then at the consumer, in particular if it is a product to be kept at the store. fresh in a refrigerator).
- the part 200 is in its final conformation and already forms the side wall 2 provided with the protrusions 2a, 2b, without however being connected to the wall of bottom 1.
- a rib S14 or similar weakening can be made to form the fold line 14 before the shaping step 52.
- the groups of horizontal ridges FL1 in the protrusion 2b and / or of ridges FL2 with a vertical component on either side of the groove S14 can be produced before step 52, respectively by pressure of at least an organ with indentations / reliefs.
- a sachet with a content that can be associated with the product P of the container can accompany the container 10 by also being attached to the cord, collar, carabiner or similar connecting element.
- the bottom walls 1 are also made from a rolled material reel, preferably comprising a layer of paper or cardboard, for example the same material as the side wall. 2.
- a shaping step 55 is performed to bend the shape. peripheral annular region of the corresponding part, so as to obtain the peripheral bend LP and create the border 1b, here surrounding an assembly member 18 with a frustoconical footprint.
- connection between the wall elements 1 and 2 is for example made by a step 61 of positioning with overlap of the fixing part FP1 on the edge 1b, after which the side wall 2 is held in a fixed predetermined position. relative to the back wall 1.
- FIG. 8 illustrates a last step 62 consisting of a hot fixing of the bottom wall 1.
- the receptacle 10 ready to be filled can then be obtained by carrying out heating and possibly a pressure treatment, making it possible to attach in a sealed manner. the external face of the border 1b inside the fixing part FP1.
- one or more waterproofing treatments can be carried out WQ ⁇ J / yS ⁇ P at step 62 or after step 62.
- the filling as shown in Figure 1, using any type of product P dose pouring system, can then be carried out, before the final closing step, by making the sealing zone Z or Z1, Z2.
- FIG. 1 shows a container 10 of which the side wall 2 is made in one piece
- a side face including added parts can be provided. It is also possible to insert in the side wall 2 all kinds of elements facilitating the grip, in particular one or more textured surfaces, ribs or other comparable surface characteristics, only on the side of the protrusion 2b or elsewhere.
- a ring possibly with an elastic return effect
- a sleeve may be provided, for example configured to surround an upper part of the external face of the side wall 2.
- a rigid cup with a section comparable to the section of the opening O of the container 10 in an open state can also form a support for the container 10.
- Such a reusable ring or cup makes it possible for the cross section of the upper end of the side wall 2 d to pass more easily.
- 'an elongated oval shape elongated in the direction of the respective interstices N1, N2 formed between the two protrusions 2a, 2b) to a substantially circular shape which can facilitate the consumption of the product P, if necessary using a spoon.
- the ring or cup can be used to obtain the conformation shown on the right of figure 7, typically after having folded the protrusion 2b.
- filling from the top is preferred as illustrated in FIG. 1, filling with product P can be carried out in various ways, possibly from the bottom before carrying out a final closing step from below in certain variants. , the filling can then be carried out opposite the opening O provided to recover / consume the product P.
