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.

  • 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.

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.

  • 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.

  • 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.
