Definitions

  • the present invention relates to a reinforced carton box, of the type obtained by overlapping two monoblock laminated elements, an external one, intended to form the wrapping of the case box and provided with an articulated cover obtained from the same external element, and the other one internal, intended to form a reinforcing element at the walls of the external wrapping.
  • the case box may be used to contain a granulated product such as washing powder, even with large volumes and weights of about 3 ⁇ 5 kg.
  • the case box could be used to package cigarettes, sweets, pills, medicines, etc.
  • object of the reinforcing element is to strengthen the side walls of the case box, usually parallelepiped-shaped, with the cover occupying an end portion of the case box.
  • the technical problem underlying the present invention is that of providing a case box overcoming the drawbacks mentioned with reference to the known art.
  • a reinforced case box characterised in that the internal element has at least one first extension and at least one second extension, integral to the internal element and articulated thereto at an edge thereof, which are folded so as to lie interposed between the internal element and the external element in correspondence of a line separating, in the external element, a portion intended to make said articulated cover, said first extension being glued to the cover portion and said second extension being glued to the external element or to the internal element so that they, upon having separated the first extension from the internal element, reciprocally interfere during the opening up and the closing of the cover.
  • the main advantage of the case box according to the present invention lies in allowing an easy assembling and providing a system that prevents the accidental or unknowing opening up of the case box itself.
  • the case box 1 is parallelepiped-shaped, with an end or bottom wall 2, four side walls of which two greater ones 3, opposite and with a greater width, form the two front portions of the case box, whereas the other two smaller ones 4, opposite and with a lesser width, operate as connections.
  • the case box 1 In a position opposite to the bottom wall 2, the case box 1 comprises a cover 5 that, in this embodiment, entirely occupies the end portion and is articulated to the body of the case box at an edge of one of the greater walls 3.
  • the case box 1 comprises interference means 6 comprising a pair of first interfering elements 7, connected to the cover 5 and substantially hook-shaped, and a second interfering element 8, connected to the wall 3 of the case box 1 and operating as stop.
  • the first interfering elements 7 are intended to be inserted into a slot 9 formed by the approaching of said greater wall 3, as part of the external wrapping of the case box 1, and of an internal reinforcing element 10.
  • the second interfering element 8 is instead interposed between the greater wall 3 and the reinforcing element, it being connected to the greater wall 3.
  • the first and second interfering elements 7, 8 are intended to cooperate for hindering the undesired, accidental or unknowing opening up of the cover 5, when the first interfering elements 7 are completely inserted into said slot 9 in a stopping position with respect to the second element 8.
  • the walls 2, 3, 4 and the cover 5 of the case box 1, forming the external wrapping thereof, are made up, by folding and gluing steps, of a plane monoblock laminated element, of paper material and in particular carton with a face suitable for being printed, hereinafter referred to as external element 100, shown in figure 1.
  • the external element 100 is formed by four rectangular panels, denoted by 101, 102, 103 and 104, respectively, arranged in sequence and separated by respective transversal central creasing 105, 106, 107, corresponding to the drawn-near long side of each panel. They are subdivided into greater 101, 103 and smaller 102, 104 panels, respectively intended to form the greater 3 and smaller 4 walls of the case box 1.
  • bottom flaps 108 and bottom tabs 109 respectively articulated to the greater panels 101 and 103 and to the smaller panels 102 and 104 at a longitudinal bottom creasing 110.
  • the bottom flaps and tabs 108, 109 are intended to form, by folding and adequate gluing, the bottom wall 2.
  • top flaps 111 and top tabs 112 respectively articulated to the greater panels 101 and 103 and to the smaller panels 102 and 104 at a longitudinal top creasing 113.
  • top flaps and tabs 111, 112 are intended to form, by folding and adequate gluing, the cover 5.
  • the external element 100 comprises, at a side edge thereof, a fastening flap 114 articulated on a transversal side creasing 115.
  • the external element 100 Near to the longitudinal top creasing 113, the external element 100 has a separation line 116 extending parallelly thereto.
  • the separation line 116 is obtained by associating, e.g. gluing it according to a conventional technology, a thread or a thin strip of resisting material.
  • the thread could also be buried into the thickness of the external element 100.
  • One end of the thread, not shown, is contained into a grip tang 117 arranged at the side edge 118 of the external element 100 opposed to the fastening flap 114.
  • the strip could also be laid continuously and without interruptions, over the entire longitudinal extension of the external element 100.
  • the one to which the fastening flap 114 is articulated said strip, corresponding to the continuous separation line 116, is interrupted with respective notches arranged near the respective transversal creasing 105, 115 delimiting the external element 100.
  • the separation of the external element 100 is effected only at the fourth, third and second panel 104, 103, 102 in order of separation, whereas at the first panel 101, at the first opening up of the cover, it is formed a longitudinal central creasing 119 corresponding to the portion of separation strip punched by the notches.
  • Said creasing 119 forms the articulation between cover 5 and body of the case box 1.
  • Said separation line 116 could also be made otherwise, e.g., by a nicking, a notching with total detachment of the portion thus defined and intended to form the cover 5, or a preferential tearing line.
  • the internal reinforcing element 10 is a plane monoblock laminated element 10, made of carton of a reinforcing type, formed by four rectangular panels, denoted by 11, 12, 13 and 14, respectively, arranged in sequence and separated by respective transversal central creasing 15, corresponding to the drawn-near long side of each panel. They are subdivided into greater 11, 13 and smaller 12 and 14 panels, respectively intended to be overlapped to the greater 3 and smaller 4 walls of the case box 1.
  • the internal element 10 comprises a fastening flap 16 articulated on a transversal side creasing 17.
  • the height of the panels 11, 12, 13 and 14 is substantially equal to that of the corresponding panels 101, 102, 103 and 104 of the external element 100. Also the widths of the respective panels are equal, so as to obtain, by overlapping the two elements 10, 100, also an overlapping between the transversal central creasing 105, 15.
  • a greater panel, denoted by 13, of the internal element 10 has, in correspondence and at the centre of the top edge 18, at least one first extension 7 and at least one second extension 8, integral to the internal element 10 and articulated thereto at said top edge 18.
  • the first extensions are two and correspond to said first interfering elements 7, whereas the second extension corresponds to said second interfering element 8. For this reason, their number references are the same.
  • the second extension 8 is articulated onto the reinforcing element 10 by a creasing 19 corresponding to said top edge 18.
  • the former is symmetrical with respect to a transversal central axis and has a pair of stopping edges 20 separated by a central extension 27.
  • the distance between stopping edges 20 and creasing 19 is substantially equal to the distance lying, in the external element 100, between separation line 116 and longitudinal top creasing 113, for the reason that will be explained hereinafter.
  • the distance between stopping edges 20 and creasing 19 may be slightly greater than the distance, in the external element 100, between separation line 116 and longitudinal top creasing 113.
  • the first extensions 7 are substantially hook-shaped, having respective hooking edges 21 corresponding to said stopping edges 20.
  • the extensions 7 are articulated onto the reinforcing element at additional separation lines 22, parallel to the top edge 18 yet slightly staggered with respect to the creasing 19 of the second extension 8, such as to be traced into the reinforcing element 10.
  • Additional separation lines 22 operate also as creasing and, in the present embodiment, are formed by preferential tearing lines 22 made by a sequence of through notches.
  • glue depositions are carried out, in particular onto the first greater panel 101, onto the first smaller panel 102 and also on the second greater panel 103, which contains the separation line 116, with glue points arranged above the separation line 116, then onto the portion intended to form the cover 5, and onto the body of the second greater panel 103, below the separation line 116 (figure 3).
  • the glue depositions are carried out according to conventional modes.
  • the glue points below the separation line 116 are preferably a single wall glue point 23, whereas the glue points thereabove are a pair of cover glue points 24.
  • the overlapping will be such that the longitudinal top creasing 113 of the external element 100 overlaps the top edge 18 of the internal element 10, and that the transversal creasing of the two elements overlap therebetween.
  • the extensions 7 and 8 Prior of carrying out said overlapping, the extensions 7 and 8 are folded (figure 4) onto the face of the internal element 10 intended to contact the external element 100, so that, once the overlapping is carried out (figure 5) said extensions 7 and 8 lie overlapped between the internal element 10 and the external element 100 at a separation line, i.e. the line separating, in the external element 100, a portion intended to form said articulated cover 5.
  • the distance between the top edge 18 of the internal element 10 and the separation lines 22 of the first extensions 7 causes, once the folding of the extensions 7, 8 has ended, a spacing between the stopping edge 20 and the hooking edge 21.
  • the glue points 23, 24 arranged onto the second greater panel 103 are positioned so that the first and second extensions 7, 8, respectively, overlap thereon.
  • said first extensions 7 glue to the portion of the cover 5 and said second extension 8 glues to the body of the external element 100 at the panel intended to form the front wall (figure 5).
  • the making up of the case box 1 occurs substantially conventionally: onto the fastening flaps 114 and 16 of the external 100 and internal 10 elements there are carried out adequate glue depositions 25, 26 (figure 6) and then the two elements are folded (figure 7) so that said flaps 116, 14 be adhered to the opposite panels 104, 14 (figure 8) thereby forming the side walls 3, 4 of the case box 1.
  • the bottom flaps and tabs 108, 109, as well as the top flaps and tabs 111, 112 are selectively provided with glue depositions (figure 9) and folded (figure 10) to form respectively the bottom wall 2 and the cover 5 of the case box 1 (figure 11), that thereby is completely formed.
  • step of filling the case box 1 is omitted from the illustration; said step will occur entirely conventionally thanks to an intermediate step.
  • the extensions 7 and 8 are respectively glued to the external element 100 so that they, upon having separated the first extension 7 from the internal element 10, reciprocally interfere during the opening up and the closing of the cover 5 of the case box 1.
  • this pressing will allow, by acting on the separation lines 22, to detach the first extensions 7 from the internal element 10.
  • the shape and number of the extensions linked to the cover and/or body of the case box are variable.
  • the second extension 8 could be glued also to the internal element 10, by suitably positioning a glue point on the sense of the second extension 8.
  • the extensions 7, 8 could also be both positioned below the top edge 18, so as to glue the element 8 onto the cover 5 without folding it and therefore without folding the two additional elements 7, so that the blocking system works in the same manner, albeit mirror-like, and with a reduced carton consumption, the two interfering elements being comprised in the height of the reinforcing element 10.
  • the present invention could be made with a case box even different from the parallelepiped-shaped one.
  • the cover could only partially occupy one wall of the case box, or even be transversal to two or three of them.
