Definitions
- the invention relates to packaging, comprising on the one hand, a container having side walls meeting at corners, a bottom and an upper opening, as well as a cover intended to close the upper opening of the container.
- the field of the invention is that of plastic packaging conventionally obtained by injection molding of the lid and the container, and both cooperating elastically.
- a package is known from the state of the art in which the container and the lid respectively have a first engagement part, at the level of the upper opening of the container, and a second engagement part, at the periphery of the lid intended to fit into one another, elastically.
- the first engagement part of the container comprises an edge directed outwards, and extending over the periphery, the second engagement part of the lid being provided with an edge, directed inwards, arranged on a skirt of the second engagement part, which is able to hook below the edge directed towards the outside of the container, to ensure the locking of the lid on the container.
- the outward-facing edge of the container, on the one hand, and the inward-facing edge of the lid, on the other hand, have curved angle sections in the corners where said side walls meet, said sections curved angles connecting the side sections of the respective edges.
- Removing the lid is typically carried out by the end user, and may prove difficult for some, or even require the help of a tool such as a screwdriver to detach the lid from the container.
- One of the solutions is disclosed by the document EP 0 110 859 and consists of providing a folding skirt section on the cover, at one of the curved angle sections of the edge directed inwards, articulated to a folding zone, such as a flexible hinge, at the upper part of the second engagement portion of the cover.
- This folding skirt section is able to fold from an engagement position towards a position directed outwards so that a central part of said at least one angle section of the edge directed inwards is moved away by leverage from the edge directed towards the outside of the upper opening, and that the engagement between the edges respectively directed towards the inside and the outside is thus weakened on the central part.
- the folding skirt section In the engaged position, the folding skirt section is separated from the remaining skirt section by means of two grooves formed in the outer surface of the skirt and extending downwardly from a folding area to the lower edge of the skirt, said grooves reducing the wall thickness of the skirt so that the skirt can be broken along the grooves to fold the folding skirt section, from its engaged position, towards its facing position the exterior.
- Such a solution comprising a folding skirt section greatly facilitates the opening of the lid where it is most difficult (ie a corner), by weakening the connection between the lid and the container in this corner, and advantageously combines an opening indicator function, the two breakable grooves being broken irreversibly, after raising the skirt section.
- the inwardly directed edge is carried by the folding skirt section, located below the flexible hinge between the folding skirt section and the second engagement part. It is however possible to provide the edge directed inwards above the flexible hinge, as disclosed by the document EP2523866 , and so that this edge is not cut when lifting the folding skirt section, and in order to preserve the seal between the lid and the container after the first opening.
- the two grooves separating the skirt and the folding skirt section are broken, indicating that the packaging has been opened.
- the end customer may notice that the breakable grooves, which act as opening indicators, have been broken during transport, and thus decide to refuse delivery, which constitutes a significant financial loss.
- such an opening indicator is however not completely reliable: it remains possible to detach the lid from the container, while maintaining the folding skirt section in its engaged position, this that is to say without having to raise it, and thus cut the two breakable grooves.
- the aim of the present disclosure is to overcome the aforementioned drawbacks by proposing a packaging comprising a lid and a container of the type as described in the document EP 0 110 859 or FR 3 081 449 A1 , which includes a folding skirt section making it easy to detach the cover, drastically reducing the number of accidental openings of the folding skirt sections.
- Another aim of the present disclosure is to propose, at least according to one embodiment, such packaging limiting the risks of fraudulent openings, namely the detachment of the cover without breaking the breakable grooves serving as an opening indicator.
- Another aim of the present invention is to provide such packaging whose design does not complicate the injection molding equipment necessary for its manufacture, and therefore its cost price.
- Another aim of the present invention is to provide such packaging whose resistance to load during stacking of the packaging is significantly improved compared to the aforementioned state of the art.
- the invention also relates to a method of manufacturing a package according to the invention in which said cover and said container are obtained by injection molding.
- the present invention firstly relates to packaging as described in claim 1 comprising, on the one hand, a plastic container, comprising side walls meeting at corners, a top opening and a bottom, and on the other hand, a cover, detachable plastic configured to cover the upper opening of the container, and in which the container is provided at its upper opening with a first engagement portion carrying an edge directed outwards, and extending over the periphery, said cover being provided on its peripheral part with a second engagement portion extending folded downwards provided with an edge, directed towards the inside which is able to hook below the edge directed towards the outside of the container, and in which the second portion engagement portion of the lid has a skirt extending over the lower part of the second engagement portion, and in which the edge of the container directed outwards, on the one hand, and the edge of the lid directed towards the interior, on the other hand, having curved angle sections in the corners where said side walls meet, said curved angle sections connecting the side sections of the respective edges, where at least one of the curved angle sections of the in
- the container comprises, at the level of the folding skirt section of the cover, a receiving portion forming a shield for the free end of the folding skirt section, with a housing receiving said free end in the position of engagement of the folding skirt section, said receiving portion being configured to prohibit folding of said folding skirt section to said outwardly directed position, and wherein said receiving portion is configured to be deformed to release the end free and allow the pivoting of the folding skirt section from the engagement position towards said position directed outwards.
- the housing comprises a front wall, extending overlapping, in front of the free end of the folding skirt section in the engagement position of the folding skirt section, said front wall then constituting a stop preventing the folding of said folding skirt section towards said position directed outwards, and in which said front wall is configured to be deformed by an operator to a retracted position allowing the free end to be released and the folding skirt section to be able to pivot around the folding zone from the engagement position towards the outward pointing position.
- the free end of the folding skirt section has a curved profile, along a plane parallel to the cover, and in which the housing of the receiving portion has, in length, a curved trajectory receiving the curved profile of the free end.
- the front wall is secured to its longitudinal ends via material bridges respectively connecting the longitudinal ends of the front wall and the side or corner walls of the container, and in which a groove reducing the thickness of the wall frontal is provided at one of the longitudinal ends of the front wall, configured so as to break by separating the longitudinal end of the material bridge when the front wall is deformed to the retracted position.
- the front wall deformed after breaking the groove to the retracted position and allowing the skirt section to be folded towards the position directed outwards is still adjacent to the container via the other longitudinal end .
- the engagement portion of the container carrying the edge directed outwards extends and extends below the edge, called the first edge, and ends below the first edge, by a second edge, also directed outwards
- the housing receiving the free end of the folding section comprises a dorsal wall whose upper end is secured to said second edge, the dorsal wall being secured to the front wall via a bottom wall connecting the lower end of the back wall and the lower end of the front wall, the section comprising the front wall, the back wall and the bottom wall forming a section of the U-shaped housing receiving the free end of the folding skirt section
- the folding skirt section carries at least one lug, directed inwards, which in the engagement position of the folding skirt section, is able to hook under the second edge directed towards the exterior of the first engagement portion, at least when a force is applied to the cover tending to detach it, and in which the attachment of said at least one lug on the second edge is carried out, in the engagement position of the folding skirt section in a local zone only along the curved angle section of the second edge directed towards the exterior, and with a hooking overlap between the mutually engaging faces of said at least one lug and the second edge, when seen in a radial direction to the curved section of the second edge, of dimension greater than the hooking overlap between the mutually engaging faces of the inwardly directed edge and the first outwardly directed edge, when viewed in a direction radial to the curved section of the first edge.
- the attachment of said at least lug under the second edge is carried out at the level of a local zone devoid of dorsal wall.
- the folding skirt section of the cover having a through recess extending along the height of the folding skirt section, above and to the right of said at least one lug.

- said foldable skirt section is separated from the remaining skirt section by means of two grooves formed in the outer surface of the skirt and extending downward from the folding zone to the lower edge of the skirt, said grooves reducing the wall thickness of the skirt so that the skirt can be broken along the grooves to fold the collapsible skirt section from its engaged position to its outward facing position
- the container has four side walls meeting at four corners, the edge directed towards the inside of the cover having four sections of curved angle with four sections of folding skirt, and four receiving portions respectively receiving the ends free of the four sections of folding skirt
- the folding skirt section carries said at least one lug, as well as the edge directed inwards, both positioned under the folding zone, in the engagement position of the folding skirt section .
- the first engagement part of the container extends below the edge directed outwards by first clipping means and the second engagement part extends below the directed edge inwards by second clipping means, said first clipping means and second clipping means being mutually engaging; at an intermediate local area along the edges of the container on the side sections between the curved angle sections where the inward-facing edge of the lid engages the outward-facing edge of the container.
- the first clipping means comprise at least one opening
- the second clipping means comprise an elastically deformable tooth, configured to be inserted elastically into said opening by hooking it.
- the peripheral wall of the cover immediately extending the second engagement part comprises along the edges of the cover on the lateral sections between the curved angle sections, where the edge directed towards the inside of the cover hooks the 'edge directed towards the outside of the container, counter-support ribs, projecting, vertical, positioned under the cover, oriented towards the outside, forming between the curved angle sections a plurality of counter-supports on the internal faces of the side walls of the container, distributed over the periphery of the container, reinforcing the hooking between the ridges hooking along the edges of the cover between the curved angle sections.
- said packaging comprises wedging ribs, extending projecting over the periphery of the cover, inwards relative to the second engagement part and upwards relative to the horizontal wall of the cover , said wedging ribs being distributed over the inner periphery of the second engagement part, so as to receive between them by centering it the lower part of a container of identical packaging superimposed on the horizontal wall of the cover, said ribs of wedging constituting stops with the lower part of the side walls of the superimposed container.
- the container has external ribs each extending vertically below the first engagement portion, each rib having at its lower end a plate intended to cooperate in abutment with the upper edge of the upper opening of the container inside which the container is stacked, the exterior ribs being provided at least partly in the corners, extending vertically below each receiving portion, at least up to the height of the receiving portion .
- the present invention also relates to a method of manufacturing a package according to claim 16 in which said cover and said container are obtained by injection molding.
- the invention relates to a packaging 1 comprising, on the one hand, a plastic container 2, comprising side walls 20, 21, 22, 23 meeting at corners 24, an upper opening 25 and a bottom 26, and on the other hand, a cover 4, detachable plastic configured to cover the upper opening of the container.
- the side walls 20, 21, 22, 23 can be substantially divergent, forming a truncated pyramid between them, configured so that the container is stackable inside an identical container.
- the container 2 is provided at its upper opening 25 with a first engagement portion 27 carrying an edge 28 directed outwards, and extending over the periphery, said cover 4 being provided on its peripheral part with a second engagement portion 40 extending folded downwards, provided with an edge 41, directed towards the inside which is able to hook below the edge 28 directed towards the outside of the container.
- the first engagement part 27 penetrates a groove of the second engagement part 40, open downwards.
- the first engagement part 27 comprises an inverted U-shaped section, including a first length section extending the wall interior upwards, followed by a second length section, inclined relative to the first section, for example horizontal, followed by a third length section, inclined relative to the second section and extending downwards, this third section carrying the edge 28 directed outwards.
- the second engagement part 40 forms a groove open downwards, receiving the first engagement part 27.
- the second engagement part 40 comprises an inverted U-shaped section, including a first section of length extending the upper wall of the cover, followed by a second length section, inclined relative to the first section, for example horizontal, followed by a third length section, inclined relative to the second section and extending downwards by forming a skirt 42, this third section carrying the edge 41 directed inwards.
- the second engagement portion of the cover thus has the skirt 42 which extends over the lower part of the second engagement portion 40, the edge 28 of the container directed towards the outside, on the one hand, and the edge 41 of the cover 4 directed inwards, on the other hand, having curved angle sections 29, 43 in the corners where said side walls meet, said curved angle sections connecting the side sections of the respective edges.
- At least one of the curved angle sections 43 of the edge 41 directed inwards is provided with a folding skirt section 44, articulated to a folding zone 46 at the upper part of the second engagement portion 40 which is able to fold from an engagement position P1 towards a position directed outwards so that a central part of said at least one angle section of the edge directed inwards 41 is moved aside by leverage of the edge 28 directed towards the outside of the upper opening, and that the engagement between the edges 28, 41 is thus weakened on the central part.
- folding skirt section makes it easier for the user to detach the cover, and without requiring the use of a tool such as a screwdriver: the weakening is obtained simply by moving the section of the skirt outwards. folding skirt 44 which pivots relative to the rest of the cover around the folding zone 46.
- said folding skirt section 44 is, in its engaged position, separated from the remaining section of the skirt by means of two grooves 45 formed in the outer surface of the skirt and extending downwardly from the folding zone 46 to the lower edge of the skirt: said grooves 45 reduce the wall thickness of the skirt so that the skirt can be broken along the grooves in order to fold the folding skirt section, from its position engagement P1, towards its position directed outwards.
- These grooves 45 once irreversibly broken, constitute indicators of openings.
- the container comprises, at the level of a folding skirt section 44 of the cover 4, a receiving portion 7 forming a shield for the free end El of the folding skirt section 44, with a housing 70 receiving said free end El of the folding skirt section 44 in the engagement position P1 of the folding skirt section 44.
- Such a receiving portion 7 is illustrated in detail according to an exemplary embodiment according to the views of the figures 7 to 11 .
- Said receiving portion 7 is advantageously configured to prevent the folding of said folding skirt section 44 towards said position directed outwards when said free end El of the folding section is received captive in the housing 70.
- the receiving portion is a shield preventing the inappropriate support from accidentally folding the skirt section outwards, and thus break any grooves 45 with an opening indicator function
- This receiving portion 7 is also configured to be deformed by an operator to release the free end and authorize the pivoting of the folding skirt section 44 from the engagement position P1 towards said position directed outwards.
- the operator first deforms the receiving portion 7, in order to release the possibility of pivoting of the folding skirt section 44 around the folding zone 46, then folds the section of foldable skirt; from the engagement position P1 towards a position directed outwards which makes it possible to weaken the connection at this corner.
- the operator successively performs these two operations for each corner 24.
- the housing can comprise a front wall 71, extending overlapping, in front of the free end of the folding skirt section 44 in the engagement position P1, the free end of the skirt section folding 44 then positioned between the corner 24 and said front wall 71, said front wall 71 then constituting a stop preventing the folding of said folding skirt section 44 towards said position directed outwards.
- Said front wall 71 is configured to be deformed by an operator up to a retracted position PE, in particular illustrated in dotted lines at the figure 8 making it possible to release the free end and to authorize the pivoting of the folding skirt section 44 from the engagement position P1 towards said position directed outwards
- the front wall 71 is secured at its longitudinal ends via material bridges 75 respectively connecting the longitudinal ends of the front wall 71 and the side or corner walls of the container. These bridges of material 75 take the form of vertical ribs.
- a groove 72 reducing the thickness of the front wall 71 can be provided at one of the longitudinal ends of the front wall 71 configured so as to break by separating the longitudinal end of the bridge of material when the front wall 71 is deformed to the retracted position PE.
- the groove 72 is broken, but preferably the front wall 71 is still adjacent to the body of the container, for example by the other longitudinal end of the front wall 71, and/or also via sections of the bottom wall 24.
- the engagement portion 27 of the container carrying the edge 28 directed outwards extends and extends below the edge, called the first edge, and ends below the first edge, with a second edge 30, also directed outwards.
- the housing 70 receiving the free end of the folding skirt section 44 may comprise a dorsal wall 73 whose upper end is in particular secured to said second edge 30, the dorsal wall 73 being secured to the front wall 71 via a wall of bottom 74 connecting the lower end of the dorsal wall 73 and the lower end of the front wall 71.
- the section comprising the front wall 71, the back wall 73 and the bottom wall 74 forms a section of the U-shaped housing 70 receiving the free end El of the folding skirt section 44 in the engagement position P1.
- the free end of the folding skirt section 44 has a curved profile, following a plane parallel to the cover.
- the housing 70 of the receiving portion 7 has, in length, a curved trajectory receiving the curved profile of the free end of the folding skirt section 44.
- the receiving portion 7 extends according to an advantageous embodiment over the entire length of the free end of the folding skirt section 44. This receiving portion 7 then forms a shield preventing unwanted support, advantageously over the entire length of the free end of the folding skirt section 44.
- said folding skirt section 42 can carry at least one lug 47.
- Said minus one lug 47 is directed inwards.
- said at least one lug 47 is able to hook under the second edge 30 directed towards the outside of the first engagement portion, at least when a force is applied to the cover tending to detach it.
- the attachment of said at least one lug 47 to the second edge 30 is carried out, in the engagement position P1 of the folding skirt section in a local area only, along the curved section of the second edge 30 directed outwards: the lug 47 extends along the length of the second edge 30 only on part of the second edge 30: for example the lug extends along the second edge along a dimension less than 1 /3, or even 1/5 of the length of the second edge 30 on the curved angle section.
- the hooking overlap Rac2 between the mutually engaging faces of said at least one lug 47 and the second edge 30, in a direction radial to the curved section of the second edge 30, is of greater dimension than the overlap of hooking Rac1 between the mutually engaging faces of the edge 41 directed towards the inside and the first edge 28 directed towards the outside, in a radial direction to the curved section of the first edge 28.
- said at least one lug 47 always hooks the second edge 30, due to a greater hooking overlap Rac2: for example, the hooking overlap Rac2 between said at least one lug 47 and the second edge 30 is at least two times greater than the hooking overlap Rac1 between the edge 41 directed towards the inside and the first edge 28 directed towards the outside.
- the dimension of the lug 47 directed towards the inside is much greater than the dimension of the edge 41 directed towards the inside.
- the folding skirt section 42 of the cover 4 may have a through recess 48 extending along the height of the folding skirt section 44, above and to the right of said at least one lug 47. The function of this obviously is to facilitate the unmolding of the cover after injection molding during its manufacture: otherwise the large dimension of the lug towards the inside, necessary to obtain the Rac2 hooking cover, makes demolding tedious, if not impossible without any particular arrangement of the mold.
- this through recess 48 implicitly weakens the folding skirt section 44: also this recess extends only over the area necessary to facilitate demolding, that is to say that this recess is located to the right of said at least lug 47, which itself extends over a short section of length following the angle section 43, and in order to limit the size of this recess.
- this through recess 48 implicitly weakens the folding skirt section 44: also this recess extends only over the area necessary to facilitate demolding, that is to say that this recess is located to the right of said at least lug 47, which itself extends over a short section of length following the angle section 43, and in order to limit the size of this recess.
- said through recess 48 extends, for example from its lower part from said at least one lug 47 and to the folding zone 46 between the folding skirt section 44 and the upper part of the second part d engagement 40, and only on the length of lug 47.
- the attachment of said at least lug 47 under the second edge is carried out at the level of a local zone Z devoid of dorsal wall and as visible at the Figure 11 .
- the dorsal wall 73 can extend discontinuously along the curved trajectory of the housing 70, leaving one or more local zones Z, to allow one or more lugs 47 to come into hooking overlap on the second stops 30.
- such an embodiment with lug 47 further improves the resistance to stacking of the packaging, and more particularly the holding of the lid of the lowest packaging in the stack: under the effect of the weight of the column, in state-of-the-art packaging it can happen that the lid comes off and literally finds itself pushed through the opening of the container.
- This embodiment allows, by the attachment of said at least lug, better resistance to depression.
- at least one lug 47 and at least one folding skirt section can be provided on each corner of the packaging.
- the folding skirt section 44 carries said at least one lug 47, as well as the edge 41 directed inwards, both positioned under the folding zone 46, in the engagement position P1 of the folding skirt section 44: the edge 41 directed inwards is therefore sectioned when the folding skirt section 44 is raised, from its engagement position P1.
- the edge 41 directed inwards can be located above the folding zone 46, so that the lifting of the folding skirt section does not sever the edge 41 directed inwards, preserving the properties sealing the lid with the first opening.
- the container has four side walls meeting at four corners, the edge 41 directed towards the inside of the cover having four sections of curved angle iron 43 with four sections of folding skirt 44, each carrying at least one lug 47 of the folding skirt section, capable of hanging with the second edge 30 directed towards the outside of the container.
- At least four lugs 47 ensure reliable attachment of the lid to the four corners of the container, which further increases the attachment connection between the lid and the container.
- the folding skirt section(s) 44 are protected from accidental openings, each by a receiving portion 7, the housing 70 of which holds the free end of the folding skirt section captive, and for example over the entire curved length of the free end El.
- each section of folding skirt 44 from its engagement position P1 (prohibiting removal of the cover) towards the position directed outwards (facilitating removal of the cover) after deformation of the portion reception 70, and in particular deformation of the front wall 71 in the retracted position PE where said front wall no longer constitutes a stop opposing the folding of the folding skirt section to the position directed outwards.
- any accidental folding of the skirt section 44 is eliminated, or at least drastically limited, and thus the rupture of the grooves 45 between the folding skirt section and the skirt 42, with the function of an opening indicator: these grooves 45 cannot be accidentally broken.
- lugs 47 at least according to one embodiment, in particular in the four sections of curved angle irons 43, first of all considerably increases the reliability of the opening indicators, forcing the user to break the grooves 45 to disengage the lugs 27 of the second edge 30
- the present disclosure further makes it possible to improve the resistance to stacking of the packaging, and more particularly the holding of the lid of the lowest packaging in the stack: under the effect of the weight of the column, when the sections of skirt are provided with lugs 47.
- peripheral wall 49 of the cover immediately extending the second engagement part 40 can include along the edges of the cover on the lateral sections between the sections of curved angles 43 where the edge 41 directed towards the inside of the cover hooks the edge 28 directed towards the outside of the container, counter-support ribs 50, projecting, vertical, positioned under the cover, oriented towards the outside.
- These counter-support ribs 50 are notable in that they advantageously form a plurality of counter-supports Ap on the internal faces of the side walls 20, 21, 22, 23 of the container, distributed over the periphery of the container on the side sections edges 28, 41 between the curved angle sections 43.
- These counter-supports Ap advantageously reinforce the attachment between the edges 28, 41 along the edges of the cover on the lateral sections of the edges 28,41 between the curved angle sections 43.
- the second engagement part 40 forms a groove G open downwards, receiving the first engagement part 27.
- the second engagement part 40 comprises an inverted U-shaped section, including a first length section, extending the upper wall of the cover immediately including the peripheral wall 49 extended by a central horizontal wall of the cover followed by a second length section, inclined relative to the first section, for example horizontal, followed by a third section of length, inclined relative to the second section and extending downwards forming a skirt 42, this third section carrying the edge 41 directed towards the inside.
- the peripheral wall 49 extends the second engagement part 40 by connecting the second engagement part to the horizontal wall of the cover. As visible at Figure 5 , this peripheral wall 49 can be inclined relative to the horizontal, central wall of the cover, for example by an angle ⁇ for example between 30° and 70° in particular between 45° and 70°. This wall 49 descends, from the second engagement part 40 towards the horizontal wall. This peripheral wall 49 delimits with the side walls 20; 21; 22; 23, when the lid is fixed to the container (by hooking the ribs 28, 41) a groove G, opening onto the underside of the lid 4 and which runs on the inner periphery of the container.
- the density of the ribs 50 for counter-support along the edge of the cover 4 can be, on the middle part of the lateral section between two sections of curved angles 43, greater than the linear density of the ribs 50 for counter-support on the end parts of the lateral section near the curved angle sections 43, on either side of the middle part
- Each counter-support rib 50 can be triangular in shape, adjoining the peripheral wall 49 by the largest side 51 of the so-called first triangle. side, while a second side 52 of the triangle, substantially horizontal, is oriented in the extension of the horizontal wall of the cover and in particular its underside, the third side 53 forming a support zone on the internal face of the container.
- the third side 52 has a section of greater length, forming the counter-support Ap on the internal face of a side wall of the container, and a section of lower length, notched, so as not to press on the side wall.
- the angle formed between the second side 52 and the third side 53 is advantageously rounded. This avoids the presence of a sharp angle likely to alter the contents, or even to pierce a flexible bag used to package materials inside the container.
- the cover 4 may also include wedging ribs 54, extending projecting over the periphery of the cover, inwards with respect to the second engagement part 40 and upwards with respect to the horizontal wall of the cover .
- the wedging ribs 54 are distributed over the inner periphery of the second engagement part 40, so as to receive between them by centering it the lower part of a container of identical packaging superimposed on the horizontal wall of the cover. Said wedging ribs constitute stops with the lower part of the side walls of the superimposed container, ensuring its centering on the cover.
- the counter-support ribs 50 may be, at least in part, ribs located, relative to the peripheral wall 49, in the extension of the wedging ribs 54; said counter-support ribs 50 and said wedging ribs 54 being coplanar, in pairs.
- Each wedging rib 54 extends in height from the horizontal wall of the cover and up to above the lower part of the second engagement part 40, and inwards, from the second engagement part 40 up to 'to the horizontal wall, partially covering the horizontal wall of the cover. As visible at Figure 6 each wedging rib 54 adjoins the rest of the cover at the level of a first edge 55 along the horizontal wall, at the level of a second edge 56 along the inclined peripheral wall 49, and over part of the height of the second part of engagement along of a third edge 57. In combination with the counter-support ribs 50, these wedging ribs 54 can help limit the transmission of forces under the load towards the second engagement part.
- the first engagement part 27 of the container extends below the edge 28 directed towards the outside and the second engagement part 40 extends below the edge 41 directed towards the outside. inside, by first clipping means 6 and second mutually engaging clipping means 8; at an intermediate local area along the edges of the container on the side sections between the curved angle sections.
- the first clipping means and the second clipping means cooperate only in the intermediate zone and reinforce the connection between the edges 28,41.
- the first clipping means 6 may comprise at least one opening 60, for example two openings, and the second clipping means comprise an elastically deformable tooth 80, configured to be inserted elastically into said opening by hooking it.
- the openings and teeth can each be doubled as shown.
- the shoulder carrying the openings 80 of the first engagement portion of the container is extended downwards by a wing 9f forming a handle Pg, projecting laterally from the side wall of the container.
- the container may have external ribs N extending under the first engagement portion 27. These external ribs N each thus extend vertically below the first engagement portion 27 of the container ( carrying the edge 21 directed outwards). Helmet external rib N has at its lower end a flat intended to cooperate in abutment with the upper edge of the upper opening of the container inside which the container is stacked: Such vertical external ribs N have the primary function of guaranteeing a no constant stacking between two containers when the latter are stacked one inside the other as described in the application FR 1854484 of the Applicant
- These ribs N can be provided in the corners, and extend vertically below each receiving portion 7, at least up to the height of the receiving portion 7. Two ribs N can be provided below each receiving portion . These ribs N can also be provided connecting wing 9 forming the handle Pg and the side wall 20 or 33 juxtaposed
- vertical ribs can advantageously be provided between the receiving portion 7 and the corner wall to the right of the zones Z devoid of a back wall: these can in particular be ribs N with a stacking pitch function, alone, or in combination with additional ribs NS, in particular of smaller vertical dimensions, and as visible figures 12 And 13 .

Description
L'invention est relative à un emballage, comprenant d'une part, un récipient présentant des parois latérales se rencontrant en des coins, un fond et une ouverture supérieure, ainsi qu'un couvercle destiné à obturer l'ouverture supérieure du récipient.The invention relates to packaging, comprising on the one hand, a container having side walls meeting at corners, a bottom and an upper opening, as well as a cover intended to close the upper opening of the container.
Le domaine de l'invention est celui des emballages plastiques obtenus classiquement par moulage par injection du couvercle et du récipient, et coopérant l'un et l'autre de manière élastique.The field of the invention is that of plastic packaging conventionally obtained by injection molding of the lid and the container, and both cooperating elastically.
Il est connu de l'état de la technique un emballage dans lequel le récipient et le couvercle présentent respectivement une première partie d'engagement, au niveau de l'ouverture supérieure du récipient, et une deuxième partie d'engagement, en périphérie du couvercle destiné à s'emboiter l'une dans l'autre, de manière élastique.A package is known from the state of the art in which the container and the lid respectively have a first engagement part, at the level of the upper opening of the container, and a second engagement part, at the periphery of the lid intended to fit into one another, elastically.
La première partie d'engagement du récipient comprend une arête dirigée vers l'extérieur, et s'étendant sur la périphérie, la deuxième partie d'engagement du couvercle étant pourvue d'une arête, dirigée vers l'intérieur, disposée sur une jupe de la deuxième partie d'engagement, qui est à même de s'accrocher en dessous de l'arête dirigée vers l'extérieur du récipient, pour assurer le verrouillage du couvercle sur le conteneur.The first engagement part of the container comprises an edge directed outwards, and extending over the periphery, the second engagement part of the lid being provided with an edge, directed inwards, arranged on a skirt of the second engagement part, which is able to hook below the edge directed towards the outside of the container, to ensure the locking of the lid on the container.
L'arête du récipient dirigée vers l'extérieur, d'une part, et l'arête du couvercle dirigée vers l'intérieur, d'autre part, ont des sections cornières incurvées dans les coins où lesdites parois latérales se rencontrent, lesdites sections cornières incurvées raccordant les sections latérales des arêtes respectives.The outward-facing edge of the container, on the one hand, and the inward-facing edge of the lid, on the other hand, have curved angle sections in the corners where said side walls meet, said sections curved angles connecting the side sections of the respective edges.
Dans un tel état de la technique, la mise en place et le verrouillage du couvercle sur le récipient est mis en place à force, classiquement au moyen d'un actionneur à vérin qui appuie au centre du couvercle afin de provoquer l'emboîtement de la première partie d'engagement du récipient dans la deuxième partie d'engagement, et jusqu'à ce que l'arête dirigée vers l'intérieur du couvercle passe en dessus de l'arête dirigée vers l'extérieur du récipient. Les surfaces mutuellement en engagement entre les deux arêtes s'opposent au détachement du couvercle.In such a state of the art, the positioning and locking of the lid on the container is put in place by force, conventionally by means of a jack actuator which presses on the center of the lid in order to cause the nesting of the first engagement part of the container in the second engagement part, and until the edge directed towards the inside of the cover passes above the edge directed towards the outside of the container . The mutually engaging surfaces between the two edges oppose the detachment of the cover.
Le retrait du couvercle est typiquement réalisé par l'utilisateur final, et peut s'avérer pour certains difficile, voire même requérir l'aide d'un outil tel qu'un tournevis pour détacher le couvercle du récipient.Removing the lid is typically carried out by the end user, and may prove difficult for some, or even require the help of a tool such as a screwdriver to detach the lid from the container.
L'état de la technique connait toutefois de tels emballages équipés en soi de parties fonctionnelles du couvercle et/ou du récipient, permettant de faciliter le retrait du couvercle.However, the state of the art knows such packaging equipped in itself with functional parts of the lid and/or the container, making it easier to remove the lid.
Une des solutions est divulguée par le document
Dans la position d'engagement, la section de jupe repliable est séparée de la section restante de la jupe au moyen de deux rainures formées dans la surface externe de la jupe et s'étendant vers le bas d'une zone de pliage jusqu'au bord inférieur de la jupe, lesdites rainures réduisant l'épaisseur de paroi de la jupe de sorte que la jupe puisse être rompue le long des rainures afin de replier la section de jupe repliable, depuis sa position d'engagement, vers sa position dirigée vers l'extérieur.In the engaged position, the folding skirt section is separated from the remaining skirt section by means of two grooves formed in the outer surface of the skirt and extending downwardly from a folding area to the lower edge of the skirt, said grooves reducing the wall thickness of the skirt so that the skirt can be broken along the grooves to fold the folding skirt section, from its engaged position, towards its facing position the exterior.
Une telle solution comprenant une section de jupe repliable facilite grandement l'ouverture du couvercle à l'endroit où elle est le plus difficile (i.e un coin), en affaiblissant la liaison entre le couvercle et le récipient dans ce coin, et combine avantageusement une fonction de témoin d'ouverture, les deux rainures sécables étant rompues de manière irréversible, après le relevage de la section de jupe. Dans le document
Un défaut de tels emballages, en particulier lors de leur transport, par exemple lorsqu'ils sont gerbés sur des palettes, est que des chocs peuvent provoquer des appuis malheureux sous la section de jupe repliable et être à l'origine de leur repliage accidentel. Dans un tel cas les deux rainures séparant la jupe et la section de jupe repliable sont rompues, témoignant d'une ouverture de l'emballage. Dans le cas d'un transport de produit à haute valeur, le client final peut constater que les rainures sécables, à fonction de témoin d'ouverture, ont été rompues lors du transport, et ainsi décider de refuser la livraison, ce qui constitue une perte financière importante.A defect of such packaging, in particular during their transport, for example when they are stacked on pallets, is that shocks can cause unfortunate supports under the folding skirt section and be the cause of their accidental folding. In such a case the two grooves separating the skirt and the folding skirt section are broken, indicating that the packaging has been opened. In the case of transport of a high value product, the end customer may notice that the breakable grooves, which act as opening indicators, have been broken during transport, and thus decide to refuse delivery, which constitutes a significant financial loss.
La présente Demanderesse a proposé d'adresser ce problème dans le document
- ces nervures extérieures s'étendent chacune ainsi verticalement au-dessous de la première portion d'engagement du récipient (portant l'arête dirigée vers l'extérieur), et présente à son extrémité basse un plat destiné à coopérer en butée avec le bord supérieur de l'ouverture supérieure du récipient à l'intérieur duquel est empilé le récipient : Des telles nervures verticales ont pour fonction première de garantir un pas d'empilage constant entre deux récipients lorsque ces derniers sont empilés l'un dans l'autre,
- de manière notable toutefois, et tel qu'enseigné par
FR 3 081 449 A1
- these external ribs each extend vertically below the first engagement portion of the container (carrying the edge directed outwards), and present at its lower end a plate intended to cooperate in abutment with the upper edge of the upper opening of the container inside which the container is stacked: The primary function of such vertical ribs is to guarantee a constant stacking pitch between two containers when the latter are stacked one inside the other,
- in a notable way, however, and as taught by
FR 3 081 449 A1
Selon les constatations de la présente Demanderesse, un tel positionnement des nervures extérieures au droit des sections de jupe repliable, permet de faire chuter le nombre d'ouvertures accidentelles et le nombre de rupture des rainures sécables à fonction de témoin d'ouverture lors du transport et des livraisons. Toutefois, et même si le taux des ouvertures accidentelles des témoins d'ouverture est fortement diminué, ce dernier n'est toujours pas nul. Il s'agit d'un premier problème auquel la présente divulgation apporte une solution.According to the findings of the present Applicant, such positioning of the external ribs to the right of the folding skirt sections makes it possible to reduce the number of accidental openings and the number of ruptures of the breakable grooves serving as an opening indicator during transport. and deliveries. However, even if the rate of accidental openings of the opening indicators is greatly reduced, the latter is still not zero. This is a first problem to which the present disclosure provides a solution.
Par ailleurs, et selon les constatations des inventeurs, un tel témoin d'ouverture n'est toutefois pas totalement fiable : il reste possible de détacher le couvercle du récipient, en maintenant la section de jupe repliable dans sa position d'engagement, c'est-à-dire sans avoir à la relever, et ainsi à sectionner les deux rainures sécables. Par exemple, il est bien souvent possible de détacher le couvercle au niveau d'un coin, en appuyant simultanément, d'une main, fortement sous la section de jupe, exerçant un effort tendant à décrocher le couvercle, et de l'autre main, en contraignant la section de jupe radialement vers le récipient, et de sorte à éviter que les rainures se sectionnent. On obtient ainsi le détachement du couvercle sans rupture des rainures sécables. Il est encore connu de l'état de la technique, de doubler les arêtes en accroche au niveau des coins, avec une autre paire d'arêtes, respectivement dirigées vers l'extérieur et vers l'intérieur, mutuellement engageantes à même de s'accrocher entre elles, disposées respectivement sur la première partie d'engagement du récipient et sur la deuxième partie, et afin d'augmenter l'accrochage au niveau du coin. Selon les constatations des inventeurs, prévoir une double paire d'arêtes mutuellement accrochées au niveau des coins n'interdit toujours pas une ouverture frauduleuse, car il reste possible de jouer sur l'élasticité du plastique afin de parvenir à détacher le couvercle, et toujours sans rompre les rainures sécables. Il s'agit d'un deuxième problème auquel la présente divulgation compte apporter une solution, au moins selon un mode de réalisation.Furthermore, and according to the findings of the inventors, such an opening indicator is however not completely reliable: it remains possible to detach the lid from the container, while maintaining the folding skirt section in its engaged position, this that is to say without having to raise it, and thus cut the two breakable grooves. For example, it is often possible to detach the cover at one corner, by simultaneously pressing, with one hand, strongly under the skirt section, exerting an effort tending to unhook the cover, and with the other hand , by constraining the skirt section radially towards the container, and so as to prevent the grooves from being severed. This results in the detachment of the cover without breaking the breakable grooves. It is still known from the state of the art to double the hooking edges at the corners, with another pair of edges, respectively directed outwards and inwards, mutually engaging capable of hang between them, arranged respectively on the first engagement part of the container and on the second part, and in order to increase the hooking at the corner. According to the findings of the inventors, provide a double pair of edges mutually attached to the The level of the corners still does not prevent fraudulent opening, because it remains possible to play on the elasticity of the plastic in order to detach the cover, and always without breaking the breakable grooves. This is a second problem to which the present disclosure intends to provide a solution, at least according to one embodiment.
Le but de la présente divulgation est de pallier les inconvénients précités en proposant un emballage comprenant un couvercle et un récipient du type tel que décrit dans le document

Une telle section de jupe repliable facilite le détachement du couvercle par l'utilisateur, et sans nécessiter l'utilisation d'un outil tel qu'un tournevis : l'affaiblissement est obtenu simplement en écartant vers l'extérieur la section de jupe repliable 44 qui pivote par rapport au reste du couvercle autour de la zone de pliage 46.Such a folding skirt section makes it easier for the user to detach the cover, and without requiring the use of a tool such as a screwdriver: the weakening is obtained simply by moving the section of the skirt outwards. folding
Selon la présente divulgation, ladite section de jupe repliable 44 est, dans sa position d'engagement, séparée de la section restante de la jupe au moyen de deux rainures 45 formées dans la surface externe de la jupe et s'étendant vers le bas de la zone de pliage 46 jusqu'au bord inférieur de la jupe : lesdites rainures 45 réduisent l'épaisseur de paroi de la jupe de sorte que la jupe puisse être rompue le long des rainures afin de replier la section de jupe repliable, depuis sa position d'engagement P1, vers sa position dirigée vers l'extérieur. Ces rainures 45, une fois rompues de manière irréversible constituent des témoins d'ouvertures.According to the present disclosure, said
Selon la présente divulgation, le récipient comprend, au niveau d'une section de jupe repliable 44 du couvercle 4, une portion de réception 7 formant un bouclier pour l'extrémité libre El de la section de jupe repliable 44, avec un logement 70 recevant ladite extrémité libre El de la section de jupe repliable 44 dans la position d'engagement P1 de la section de jupe repliable 44.According to the present disclosure, the container comprises, at the level of a
Une telle portion de réception 7 est illustrée en détail selon un exemple de réalisation selon les vues des
Ladite portion de réception 7 est avantageusement configurée pour interdire le repliage de ladite section de jupe repliable 44 vers ladite position dirigée vers l'extérieur lorsque ladite extrémité libre El de la section repliable est reçue prisonnière dans le logement 70. Lors du transport des emballages, et même en cas de chocs et d'appuis inappropriés dus au transport au niveau des sections de cornière incurvées, la portion de réception est un bouclier faisant obstacle à ce que l'appui inapproprié vienne malencontreusement replier la section de jupe vers l'extérieur, et ainsi rompre les éventuelles rainures 45 à fonction de témoin d'ouvertureSaid receiving
Cette portion de réception 7 est par ailleurs configurée pour être déformée par un opérateur pour libérer l'extrémité libre et autoriser le pivotement de la section de jupe repliable 44 depuis la position d'engagement P1 vers ladite position dirigée vers l'extérieur.This receiving
Ainsi et pour permettre le retrait du couvercle, l'opérateur déforme tout d'abord la portion de réception 7, afin de libérer la possibilité de pivotement de la section de jupe 44 repliable autour de la zone de pliage 46, puis replie la section de jupe repliable ; depuis la position d'engagement P1 vers une position dirigée vers l'extérieur qui permet d'affaiblir la liaison à ce coin. Dans le cas de plusieurs sections repliables à différents coins du récipient, l'opérateur effectue successivement ces deux opérations pour chaque coin 24.Thus and to allow the removal of the cover, the operator first deforms the receiving
Comme visible à titre indicatif à la
Ladite paroi frontale 71 est configurée pour être déformée par un opérateur jusqu'à une position escamotée PE, notamment illustrée en pointillés à la
La paroi frontale 71 est solidarisée à ses extrémités longitudinales via des ponts de matière 75 reliant respectivement les extrémités longitudinales de la paroi frontale 71 et les parois latérales ou de coin du récipient. Ces ponts de matière 75 prennent la forme de nervures verticales.The
Une rainure 72 réduisant l'épaisseur de la paroi frontale 71 peut être prévue au niveau de l'une des extrémités longitudinales de la paroi frontale 71 configurée de sorte à rompre en désolidarisant l'extrémité longitudinale du pont de matière lorsque la paroi frontale 71 est déformée jusqu'à la position escamotée PE.A
Une fois déformée dans la position escamoté PE, la rainure 72 est rompue, mais de préférence la paroi frontale 71 est toujours attenante au corps du récipient, par exemple par l'autre extrémité longitudinale de la paroi frontale 71, et/ou encore via des sections de la paroi de fond 24.Once deformed in the retracted position PE, the
Selon un mode de réalisation, avantageux, et tel que compréhensible de la
Le logement 70 recevant l'extrémité libre de la section de jupe repliable 44 peut comprendre une paroi dorsale 73 dont l'extrémité supérieure est notamment solidaire de ladite seconde arête 30, la paroi dorsale 73 étant solidaire de la paroi frontale 71 via une paroi de fond 74 reliant l'extrémité inférieure de la paroi dorsale 73 et l'extrémité inférieure de la paroi frontale 71.The
Comme compréhensible de la
Comme compréhensible des figures, l'extrémité libre de la section de jupe repliable 44 présente un profil incurvé, suivant un plan parallèle au couvercle. Le logement 70 de la portion de réception 7 présente, en longueur, une trajectoire incurvée recevant le profil incurvé de l'extrémité libre de la section de jupe repliable 44.As can be understood from the figures, the free end of the
La portion de réception 7, s'étend selon un mode de réalisation avantageux sur toute la longueur de l'extrémité libre de la section de jupe repliable 44. Cette portion de réception 7 forme alors un bouclier faisant obstacle à un appui non souhaité, avantageusement sur toute la longueur de l'extrémité libre de la section de jupe repliable 44.The receiving
Selon l'invention et de manière notable, et lorsque la première portion d'engagement 27 du récipient portant ladite première arête 28 dirigée vers l'extérieur s'étend et se prolonge en dessous de l'arête, et se termine en dessous de la première arête par une seconde arête 41, ladite section de jupe repliable 42 peut porter au moins un ergot 47.According to the invention and notably, and when the
Ledit moins un ergot 47, est dirigé vers l'intérieur. Dans la position d'engagement P1 de la section de jupe repliable 4, ledit au moins un ergot 47 est à même de s'accrocher sous la seconde arête 30 dirigée vers l'extérieur de la première portion d'engagement, au moins lorsqu'un effort est appliqué sur le couvercle tendant à le détacher.Said minus one
De manière notable, l'accrochage dudit au moins un ergot 47 sur la seconde arête 30 est réalisé, dans la position d'engagement P1 de la section de jupe repliable en une zone locale seulement, le long de la section incurvée de la seconde arête 30 dirigée vers l'extérieur : l'ergot 47 s'étend suivant la longueur de la seconde arête 30 seulement sur une partie de la seconde arête 30 : par exemple l'ergot s'étend suivant la seconde arête suivant une dimension inférieure à 1/3, voire même 1/5 de la longueur de la seconde arête 30 sur la section de cornière incurvée.Noticeably, the attachment of said at least one
De manière notable, le recouvrement d'accrochage Rac2 entre les faces mutuellement engageantes dudit au moins un ergot 47 et de la seconde arête 30, suivant une direction radiale à la section incurvée de la seconde arête 30, est de dimension supérieure au recouvrement d'accrochage Rac1 entre les faces mutuellement engageantes de l'arête 41 dirigée vers l'intérieur et de la première arête 28 dirigée vers l'extérieur, suivant une direction radiale à la section incurvée de la première arête 28.Notably, the hooking overlap Rac2 between the mutually engaging faces of said at least one
Les recouvrements d'accrochage Rac2 et Rac1 sont visibles à titre indicatif à la
Aussi, et en cas de tentative d'ouverture frauduleuse, et même à supposer que l'arête 41 dirigée vers l'intérieur se décroche de la première arête 28, en raison du plus faible recouvrement d'accrochage Rac1, ledit au moins un ergot 47 vient toujours accrocher la seconde arête 30, en raison d'un recouvrement d'accrochage Rac2 plus important : à titre d'exemple, le recouvrement d'accrochage Rac2 entre ledit au moins un ergot 47 et la seconde arête 30 est au moins deux fois supérieur au recouvrement d'accrochage Rac1 entre l'arête 41 dirigée vers l'intérieur et la première arête 28 dirigée vers l'extérieur.Also, and in the event of a fraudulent opening attempt, and even assuming that the
Ainsi, il devient seulement possible de décrocher ledit au moins un ergot 47 de la seconde arête 30 par le repliement de la section de jupe repliable 44 et avantageusement suivant une amplitude de déplacement obligeant la rupture des rainures 45. On augmente ainsi sensiblement la fiabilité de ce témoin d'ouverture.Thus, it only becomes possible to detach said at least one
A ce titre, on constate que la dimension de l'ergot 47 dirigé vers l'intérieur est bien supérieure à la dimension de l'arête 41 dirigée vers l'intérieur. A ce titre, la section de jupe repliable 42 du couvercle 4 peut présenter un évidement traversant 48 s'étendant suivant la hauteur de la section de jupe repliable 44, au-dessus et au droit dudit au moins un ergot 47. La fonction de cet évidement est de faciliter le démoulage du couvercle après moulage par injection lors de sa fabrication : à défaut la dimension importante de l'ergot vers l'intérieur, nécessaire à l'obtention du recouvrement d'accrochage Rac2, rend le démoulage fastidieux, voire impossible sans disposition particulière du moule.As such, we see that the dimension of the
On remarque que cet évidement traversant 48 fragilise implicitement la section de jupe repliable 44 : aussi cet évidement s'étend seulement sur la zone nécessaire pour faciliter le démoulage, c'est-à-dire que cet évidemment est situé au droit dudit au moins ergot 47, qui s'étend lui-même sur une faible section de longueur suivant la section de cornière 43, et afin de limiter la taille de cet évidement. On obtient au final un compromis entre la facilité de mise en oeuvre lors du procédé de fabrication par moulage par injection, et la résistance de l'accrochage entre la section de jupe repliable et le récipient dans ce coin.We note that this through
Tel qu'illustré à la
Dans la position d'engagement P1 de la section de jupe repliable, et lorsque qu'aucun effort extérieur n'est appliqué sur le couvercle tel qu'illustré à la
On remarque encore que l'accrochage dudit au moins ergot 47 sous la seconde arrête est réalisé au niveau d'une zone locale Z dépourvue de paroi dorsale et comme visible à la
A ce titre, un tel mode de réalisation avec ergot 47, permet encore d'améliorer la résistance au gerbage de l'emballage, et plus particulièrement la tenue du couvercle de l'emballage le plus bas dans l'empilement : sous l'effet du poids de la colonne, dans les emballages de l'état de la technique il peut arriver que le couvercle se décroche et se retrouve littéralement enfoncé au travers de l'ouverture du récipient. Ce mode de réalisation permet, par l'accrochage dudit au moins ergot, une meilleure résistance à l'enfoncement. Dans un tel cas, au moins un ergot 47 et au moins une section de jupe repliable peut être prévu sur chaque coin de l'emballage.As such, such an embodiment with
Selon le mode de réalisation illustré à la
Selon un mode de réalisation illustré, le récipient comporte quatre parois latérales se rencontrant en quatre coins, l'arête 41 dirigée vers l'intérieur du couvercle présentant quatre sections de cornière incurvée 43 avec quatre sections de jupe repliable 44, chacune portant au moins un ergot 47 de la section de jupe repliable, apte à accrocher avec la seconde arête 30 dirigée vers l'extérieur du récipient. Au moins quatre ergots 47 assurent un accrochage fiable du couvercle aux quatre coins du récipient ce qui augmente encore la liaison d'accrochage entre le couvercle et le récipient.According to an illustrated embodiment, the container has four side walls meeting at four corners, the
On remarque tout d'abord de la
La ou les sections de jupe repliables 44 sont protégées des ouvertures intempestives, chacune par une portion de réception 7, dont le logement 70 vient maintenir prisonnier l'extrémité libre de la section de jupe repliable, et par exemple sur toute la longueur incurvée de l'extrémité libre El.The folding skirt section(s) 44 are protected from accidental openings, each by a receiving
Il n'est possible de replier chaque section de jupe repliable 44, depuis sa position d'engagement P1 (interdisant le retrait du couvercle) vers la position dirigée vers l'extérieur (facilitant le retrait du couvercle) qu'après déformation de la portion de réception 70, et notamment déformation de la paroi frontale 71 dans la position escamotée PE où ladite paroi frontale ne constitue plus une butée s'opposant au repliage de la section de jupe repliable jusqu'à la position dirigée vers l'extérieur.It is only possible to fold each section of folding
Avantageusement on supprime, ou à tout le moins on limite drastiquement tout repliage accidentel de la section de jupe 44, et ainsi la rupture des rainures 45 entre la section de jupe repliage et la jupe 42, à fonction de témoin d'ouverture : ces rainures 45 ne peuvent être rompues accidentellement.Advantageously, any accidental folding of the
La présence des ergots 47, au moins selon un mode de réalisation, notamment aux quatre sections de cornières 43 incurvée augmente tout d'abord considérablement la fiabilité des témoins d'ouverture, obligeant l'utilisateur à rompre les rainures 45 pour désengager les ergots 27 de la seconde arête 30The presence of
La présente divulgation permet encore d'améliorer la résistance au gerbage de l'emballage, et plus particulièrement la tenue du couvercle de l'emballage le plus bas dans l'empilement : sous l'effet du poids de la colonne, lorsque les sections de jupe sont pourvues des ergots 47.The present disclosure further makes it possible to improve the resistance to stacking of the packaging, and more particularly the holding of the lid of the lowest packaging in the stack: under the effect of the weight of the column, when the sections of skirt are provided with
De manière notable également, on remarque encore que la paroi périphérique 49 du couvercle prolongeant immédiatement la deuxième partie d'engagement 40 peut comprendre le long des bords du couvercle sur les sections latérales entre les sections de cornières incurvées 43 où l'arête 41 dirigée vers l'intérieur du couvercle accroche l'arête 28 dirigée vers l'extérieur du récipient, des nervures de contre-appui 50, saillantes, verticales, positionnées sous le couvercle, orientées vers l'extérieur.Also notably, we note that the
Ces nervures de contre-appui 50 sont notables en ce qu'elles forment avantageusement une pluralité de contre-appuis Ap sur les faces internes des parois latérales 20, 21, 22, 23 du récipient, répartis sur la périphérie du récipient sur les sections latérales des arêtes 28, 41 entre les sections de cornières 43 incurvée. Ces contre-appuis Ap renforcent avantageusement l'accrochage entre les arêtes 28, 41 le long des bords du couvercle sur les sections latérales des arêtes 28,41 entre les sections de cornières 43 incurvée.These
Lors du gerbage d'un emballage en appui sur le couvercle d'un emballage identique, on obtient avantageusement notamment grâce aux présences combinées des ergots 47, sur les sections de jupe repliable 44, au niveau des coins, d'une part, et des nervures de contre-appui 50, le long des bords entre les coins, d'autre part, un bon maintien de l'accrochage du couvercle sur le récipient, sans décrochage des nervures 28, 41 sur toute la périphérie du couvercle, c'est-à-dire non seulement au niveau des coins, mais plus encore le long des bords entre les coinsWhen stacking a package resting on the lid of an identical package, this is advantageously obtained in particular thanks to the combined presence of
Comme visible à la
La paroi périphérique 49 prolonge la deuxième partie d'engagement 40 en reliant la deuxième partie d'engagement à la paroi horizontale du couvercle. Comme visible à la
La densité des nervures 50 de contre-appui le long du bord du couvercle 4 peut être, sur la partie médiane de la section latérale entre deux sections de cornières 43 incurvée, supérieure à la densité linéaire des nervures 50 de contre appui sur les parties extrêmes de la section latérale à proximité des sections de cornières 43 incurvée, de part et d'autre de la partie médianeThe density of the
Chaque nervure 50 de contre-appui peut être de forme triangulaire, attenante de la paroi périphérique 49 par le plus grand côté 51 du triangle dit premier côté, tandis qu'un deuxième côté 52 du triangle, sensiblement horizontal, est orienté dans le prolongement de la paroi horizontale du couvercle et notamment de sa sous face, le troisième côté 53 formant une zone d'appui sur la face interne du récipient. On remarque encore que le troisième côté 52 présente une section de longueur supérieure, formant le contre-appui Ap sur la face interne d'une paroi latérale du récipient, et une section de longueur inférieure, grugée, de sorte à ne pas appuyer sur la paroi latérale. L'angle formé entre le deuxième côté 52 et le troisième côté 53 est avantageusement arrondi. On évite ainsi la présence d'angle vif susceptible d'altérer le contenu, voire de percer une sache souple utilisée pour conditionner des matières à l'intérieur du récipient.Each
Comme visible à la
Les nervures 50 de contre-appui peuvent être, au moins en partie, des nervures situées, par rapport à la paroi périphérique 49, dans le prolongement des nervures de calage 54 ; lesdites nervures de contre appui 50 et lesdits nervures de calage 54 étant coplanaires, par paires.The
Chaque nervure de calage 54 s'étend en hauteur depuis la paroi horizontale du couvercle et jusqu'au-dessus de la partie basse de la deuxième partie d'engagement 40, et vers l'intérieur, depuis la deuxième partie d'engagement 40 jusqu'à la paroi horizontale, en recouvrant partiellement la paroi horizontale du couvercle. Comme visible à la
Selon un mode de réalisation, la première partie d'engagement 27 du récipient se prolonge en dessous de l'arête 28 dirigée vers l'extérieur et la deuxième partie d'engagement 40 se prolonge au-dessous de l'arête 41 dirigée vers l'intérieur, par des premiers moyens de clipsage 6 et des deuxièmes moyens de clispage 8 mutuellement engageant ; au niveau d'un zone locale intermédiaire le long des bords du récipient sur les sections latérales entre les sections de cornières incurvées.According to one embodiment, the
Les premiers moyens de clispage et les seconds moyens de clipsage coopèrent seulement en la zone intermédiaire et viennent renforcer l'accrochage entre les arêtes 28,41. Les premiers moyens de clipsage 6 peuvent comprendre au moins une ouverture 60, par exemple deux ouvertures, et les deuxièmes moyens de clipsage comprennent une dent 80, élastiquement déformable, configurée pour s'insérer de manière élastique dans ladite ouverture en l'accrochant. Les ouvertures et les dents peuvent être chacune doublés, tel qu'illustré.The first clipping means and the second clipping means cooperate only in the intermediate zone and reinforce the connection between the
Ces moyens 6, 8 permet de renforcer la tenue du couvercle et son accrochage sur le récipient via les arêtes 28, 41, en particulier lorsque ce dernier reprend une charge importante, telle que la charge d'un emballage en appui sur le couvercle. On augmente la résistance du couvercle à la charge, en particulier lors du gerbage des emballages l'un sur l'autre.These means 6, 8 make it possible to reinforce the hold of the lid and its attachment to the container via the
Sur deux opposés des parois latérales, l'épaulement portant les ouvertures 80 de la première portion d'engagement du récipient est prolongée vers le bas par une aile 9f formant une poignée Pg, saillante latérale de la paroi latérale du récipient. Ces deux poignées, Pg saillante latéralement de deux des parois latérales du récipient permettent de soulever l'emballage.On two opposite sides of the side walls, the shoulder carrying the
Il est encore à noter que le récipient peut présenter des nervures extérieures N s'étendant sous la première portion d'engagement 27. Ces nervures extérieures N s'étendant chacune ainsi verticalement au-dessous de la première portion d'engagement 27 du récipient (portant l'arête 21 dirigée vers l'extérieur). Caque nervure extérieure N présente à son extrémité basse un plat destiné à coopérer en butée avec le bord supérieur de l'ouverture supérieure du récipient à l'intérieur duquel est empilé le récipient : Des telles nervures extérieurs N, verticales ont pour fonction première de garantir un pas d'empilage constant entre deux récipients lorsque ces derniers sont empilés l'un dans l'autre tel que décrit dans la demande
Ces nervures N peuvent être prévues dans les coins, et s'étendre verticalement en dessous de chaque portion de réception 7, au moins jusqu'à hauteur de la portion de réception 7. Deux nervures N peut être prévues en dessous de chaque portion de réception. Ces nervures N peuvent encore être prévues reliant aile 9 formant la poignée Pg et la paroi latérale 20 ou 33 juxtaposéeThese ribs N can be provided in the corners, and extend vertically below each receiving
Comme visibles aux figures, des nervures verticales peuvent être avantageusement prévues entre la portion de réception 7 et la paroi de coin au droit des zones Z dépourvues de paroi dorsale : il peut notamment s'agir des nervures N à fonction de pas d'empilage, seules, ou en combinaison avec des nervures supplémentaires NS, notamment de plus petites dimensions verticales, et comme visibles aux
La position de ces nervures notamment des nervures N (seules ou en combinaison avec les nervures supplémentaire NS) permet de faire obstacle dans l'inter-espace entre la portion de réception 7 et la paroi de coin, au décrochage frauduleux des ergots 47 de la seconde arête 30 (à savoir sans nécessiter le repliage de la de la section de jupe 44, et la rupture des rainures 45, à fonction de témoin d'ouverture). On augmente plus encore la fiabilité du témoin d'ouverture.The position of these ribs in particular of the ribs N (alone or in combination with the additional ribs NS) makes it possible to obstruct, in the inter-space between the receiving
