  • the present invention further relates to a container comprising said coupling system and a use of said coupling system for containers, packaging, envelopes and/or bands for the containment and/or wrapping of products of various kinds.
  • the coupling system may find application in all the fields providing for the packaging of products requiring a degree of security which enables to show a possible tampering of the package.
  • the coupling system may be employed in the fields of packaging, communication (for example, for postal services), transport and logistics.
  • tamper-evident The employment of packages - made of paper or plastic material - is known, for products of various kinds and equipped with security systems defined as "tamper-evident".

  • the third sheet 56 further comprises at least one first and one second lateral connecting portion 60, 61; the central connecting portion 58 is interposed between the first and the second portion 57, 59, the first portion 57 is interposed between the first lateral connecting portion 61 and the central connecting portion 58.
  • the second portion 59 is interposed between the second lateral connection portion 60 and the central connection portion 58.
  • Each of the portions 57, 58, 59, 60, 61 comprises at least two opposite longitudinal edges and two opposite end edges.
  • the first and second portions 57, 59, central connecting portion 58 and said lateral connecting portions 60, 61 are joined along the longitudinal edges and aligned along a single connection direction.
  • the step of preparing the storage 2 further comprises a step of folding the third sheet 56, joining the lateral connecting portions 60, 61, to form the storage 2 exhibiting the passage opening 5 delimited by at least one free edge 6.
  • the lateral connecting portions 60, 61 are joined to each other by means of adhesive material.
  • the step of preparing the storage 2 may further comprise a step of preparing a fourth sheet having at least one portion connected to at least one central and/or lateral connecting portion of the third sheet and emerging with respect to the latter.
  • the portion of the fourth sheet is adapted to form a support portion 80 of the container 100.
  • the first sheet 51 is joined in a single piece to the second portion 59 of the third sheet 56; the first sheet is configured to be folded to form the closing portion 7 and the inserting portion 8 of the container 100, respectively.
  • the second sheet 53 defining the second base portion 12 of the second hooking portion 14 of the coupling system 1 is integrally joined to form a single body with the first portion 57 of the third sheet 56; in particular, the second sheet 53 emerges from the longitudinal edges of the sixth sheet 56.
  • first, second, third and optionally the fourth sheet are joined together in a single piece to define a single blank of sheet material, in particular made of paper sheet material, foldable to form said container.
