Definitions

  • the present invention relates to the technical field of reinforcement for carton packaging, such as boxes, trays and the like which are supplied in flatpack form for its later assembly by folding along the folding lines thereof.
  • These carton packages may be enabled from simple carton or corrugated carton in order to form boxes, trays and other packaging modes.
  • the packages of corrugated carton may utilize one, two or more interior layers of corrugated carton.
  • packages were enabled with one or other type of carton, while varying certain factors, such as the thickness of the laminated carton forming it, or in the case of corrugated carton, the type of corrugation, with more or less density of flutes, in other words, of the waves of the corrugation, the number of layers of corrugation... , to obtain a greater loading capacity.
  • the reference document US8317671 refers to a method of manufacture of a piece of carton to form a carton box which has an upper wall, a lower wall, and two lateral walls.
  • This method comprises a first stage consisting of having a band of non-corrugated carton advance along the length of a trajectory, this band of non-corrugated carton configures a packaging box, on being folded along the folding lines.
  • the second stage comprises laminating at least a first band and a second band of reinforcing material over the first surface of the band of advancing non-corrugated carton.
  • the first and the second bands have a lesser width than the width of the band of non-corrugated carton.
  • the first band is positioned and adheres substantially completely but not beyond a first portion of the longitudinally extended panel of the band of non-corrugated carton, and the second band is positioned on, and adhered to, substantially all, but not beyond a second portion of the longitudinal he extended panel of the band of non-corrugated carton.
  • the first and second bands do not extend across the longitudinal folding lines.
  • the third stage comprises cutting the band of non-corrugated carton and the first and second laminated bands along their length into a carton box which has panels corresponding to the upper wall, the lower wall, and the two lateral walls of the carton box, such that the first band and the second band are situated in the interior of the carton box, when the piece of carton is folded to form the same, for the reinforcement thereof.
  • the invention consists in the enablement of the carton box and the reinforcement thereof in a single process. This complicates the manufacture thereof and is expensive, since a special machine is required to be able to complete the process.
  • the reinforcements are formed by equal layers adhered one atop the other without any sequence or order, which results in the laminate so generated being incapable of folding when in excess of a certain thickness of laminate. This presupposes the existence of a limitation on the thickness of the reinforcement.
  • That invention is focused on simple carton, which is non-corrugated, and as such excludes the option of reinforcement of packages enabled using corrugated carton, and that is currently one of the most frequently utilized.
  • the reference document US8443975 defines anedge protector, which comprises a first section formed from a laminate of layers of paper or carton.
  • the first section is formed with an angular configuration which defines the first and second sides, defining a first vertex there between.
  • the first vertex defines a first interior corner and a second exterior corner, and said first and second sides, as well as the first vertex which define a first width.
  • the protector comprises a second section formed from a laminate of layers of paper or carton which cover a central or nuclear element. This nucleus and the laminate are disposed in an angular configuration similarto the first section, defining the third and fourth sides, which define a second vertex there between.
  • the second vertex in turn defines a third interior corner and a fourth external corner, and the third and fourth sides and the second vertex defines a second width which is less than the first width, wherein the layers which cover the central or nuclear element wrap around the fourth external corner and extend inward towards the third interior corner.
  • the first and second sections are mutually adhered with the first and third sides joined there between, as well as the second and fourth sides also been joined there between.
  • anedge protector which presents an angular shape and is formed from a series of mutually superimposed layers and constitutes two sections, one with longer sides than the other and both adhered by their respective two sides.
  • This edge protector is disposed on the corners of the packets and serves to improve the resistance thereof.
  • the proposed edge protector does not facilitate its disposition in the unassembled packages, since the disposition thereof would involve the previous assembly of the package and the transportation thereof in the assembled state, since the protectors present a right angular shape and the configuration of the same based on sheets thereof being adhered along the length of the width of the sections which form them, and that disposition in a right angle being fixed and invariable.
  • the support points of the base of the package do not present any type of reinforcement, such that this support of each protector presupposes a concentration of forces at said points of the base, resulting in the package possibly collapsing.
  • the reinforcement forcarton packages such as boxes, trays and the like, which are supplied in flatpack form, for their later assembly by folding along their fold lines which is presented here, comprises a longitudinal profile of reinforcement formed from two longitudinal segments disposed in the same horizontal forming an angle of 180° and a joining central zone of the same, which can be folded to form an angle of from 0 to 180° between the segments.
  • the longitudinal profile presents a laminated structure formed by at least a first and second superimposed layers and means for joining between the layers.
  • Said first and second layers are formed by a first sheet of carton whose width is equal or greater than double the width of the longitudinal profile, while the first layer is formed by an intermediate zone of said first sheet which has a width equal to the width of the longitudinal profile, and the second layer is formed by folding lateral strips of the first sheet to both sides of the intermediate zone and folding over the same.
  • each longitudinal profile segment comprises at least one additional layer disposed between the first and second layer, wherein said at least one additional layer is formed by a sheet of carton whose width is equal to the width of said profile segment, wherein both segments present the same number of additional layers.
  • the longitudinal profile additionally comprises at least one intermediate layer, disposed between the first layer and the second layer, formed by a sheet of carton of a width equal to the sum of the values of the width of both profile segments and that of the central zone of the same.
  • the at least one intermediate layer of the longitudinal profile is located over the central line of the transverse section of the same.
  • the transverse section of the longitudinal profile comprises at least two intermediate layers, not only in the case where there is an intermediate layer over the central line of the transversal section of the longitudinal profile, but also when that is not the case, wherein the intermediate layers are disposed in a symmetric manner with respect to the central line of said transversal section.
  • the reinforcing longitudinal profile is capable of been bent to both sides, both in the case where there is an intermediate layer with a longitudinal profile disposed over the central line of the transverse section of the same, or intermediate layers disposed in said section in a symmetrical manner, or better still intermediate layers disposed symmetrically about the central line of the section.
  • the transverse section of the longitudinal profile comprises at least one intermediate layer disposed in an asymmetric manner with respect to the central line of said transverse section, proximal to the first or the second layer of the section, and the profile is capable of being bent to the opposite side to that in which the intermediate layers are disposed.
  • the width of the central zone of the joint of both longitudinal profile segments is equal to or greater than the thickness of the profile of said segments and less than double said thickness, as well as the longitudinal profile being capable of forming a minimum angle of 90° between the segments.
  • the width of the central zone of the joint of both segments of the longitudinal profile is equal to or greater than double the thickness of said segments and is capable of forming a minimum angle of 0° between the segments.
  • the joint means between the layers of the longitudinal profile are formed by a glue or adhesive material.
  • This invention also comprises a carton package with reinforcement for packages, wherein the reinforcement is that defined in this invention and wherein the carton package is formed by a planar laminate of carton with folding lines for its later assembly by folding via said folding lines.
  • each longitudinal profile is suited to the disposition thereof in at least two parallel folding lines of the packaging, wherein each folding line starts at the side of the laminate of planar carton, and the end thereof is in the opposite side of said laminate and wherein, in the folded position of the package, each of these folding lines comprises at least two vertical joint edges between the sides and the horizontal edge of the base of the package.
  • the package is formed by a laminate of corrugated carton, which comprises two external layers of lining and at least one layer of corrugation there between, and each longitudinal profile of reinforcement is integrated in the interior of said laminate, on at least one of said layers of corrugation of the laminate of carton.
  • each longitudinal profile of the reinforcement is situated over said laminate of carton of the package.
  • the disposition of the reinforcements may be enabled manually, by the adherence thereof over the folding lines, or in a mechanized manner in the case of corrugated carton packages, integrating the disposition of the reinforcements, enabled previously, in the same process of implementation of the corrugated carton laminate. In this manner, the reinforcement is introduced between the external layers of lining of the corrugated carton during the manufacture thereof.
