Definitions

  • This invention relates to a box with a security closure destined to contain, for instance, bottles for medicinal substances.
  • This type of box must also satisfy other requirements: it must allow the user to close and reopen the box again when necessary.
  • the box must be low cost, easy to assemble and capable of being assembled with high-speed packing lines.
  • One purpose of the present invention is to furnish a box that is able to satisfy these demands simultaneously.
  • the projecting portion that projects internally into the box, and/or the flap that engages this projecting portion are provided with means that allow for at least partial laceration once the box has been opened.
  • the die-cut blank 1 is shown in its open form and from the printed side, i.e. from the side that corresponds to the external side of the assembled box.
  • the die-cut blank is divided into portions, 3, 5, 7, 9 respectively by parallel fold lines 11, 13, 15 and comprises an edge 4 that allows the die-cut blank to be folded and glued to form a tubular body 2 (Fig. 2).
  • the closure of the tubular body 2 is normally effected by means of wings and flaps like, for instance, the lower wings 17 and 19 and the flap 21 that project downward from the die-cut blank portions 3, 7 and 9 respectively. They serve to close the bottom of the box.
  • Secondary lower fold lines 23, 25, 27 are respectively provided between each wing or flap and its respective portion.
  • the flap 21 presents, in its free extremity, a fold 33 that finishes in its two extremities with cuts 37, 35 respectively.
  • the fold 33 is more internal with respect to the cuts 37 and 35, i.e. it is offset slightly toward the fold 27.
  • the cuts 37, 35 are around 2 mm longer than the teeth 29, 31 as they serve to engage the same teeth respectively after the closure of the lower base of the box.
  • This type of closure is known in the art but doesn't guarantee the inviolability of the packaging in that it is not possible to say whether the box has been opened and closed again. Therefore, in the box according to the present invention this system of lower closure will have been completed or replaced by a glued system, of a type known in the art, between wings and flap 21.
  • the flap 39, the wings 41 and 45 and the additional wing 43 respectively project upward from the portions 9, 7, 5, 3.
  • Lines of secondary upper fold 40, 42, 44, 46 are provided between the upper elements 39, 41, 43, 45 and the portions 9, 7, 5, 3 respectively.
  • the wing 43 is equipped with an opening 47.
  • This opening 47 has such a profile as to define a tongue 49 that projects towards the inside of the opening and is directed substantially toward the free extremity of the flap 43.
  • the secondary upper fold line 44 extends for about the length of the opening 47 and finishes each extremity with partial cuts, i.e. "half cuts" of the thickness of the die-cut blank, 57 and 59, which facilitate the folding of the flap.
  • the flap 43 is subsequently folded up and its free extremity is glued to the inside surface of the portion 5 as shown in Fig. 2, so that, due to the fold 44 and to the partial cuts 57 and 59, the tongue 49 projects toward the interior of the box, distancing itself from the portion 5.
  • the flap 39 is provided in proximity of its free extremity with a slot 55 in which (with box closed) the tongue 49 engages and with a fold line 61 that terminates with cuts 63, 65 to facilitate the folding of the same free extremity.
  • the flap 39 could also be equipped with two break-off lines 51, 53 that link the slot 55 to the free extremity of the same flap.
  • flap 39 On the flap 39 there are also provided a pair of fold lines 67, 69 that converge in direction of the slot 55. These lines together with the cuts 63 and 65 serve for make the flap 39 elastic and permit the flap 39 to be pressed toward the interior of the box in the packing phase until the slot 55 engages with the tongue 49. In this way, when the flap 39 is released, it returns elastically to its position of rest, hooking the tongue 49 in a secure way.
  • the wing 41 is provided, in correspondence with the side that lies on the prolongation of the fold 13, with a missing portion forming a tooth 71.
  • Equally the wing 45 is provided, in correspondence of the side that lies on the prolongation of the fold 11, with a missing portion forming a tooth 73.
  • the teeth 71 and 73 present a greater height than the depth respectively of the cuts 65 and 63 to prevent the first from getting jammed in the second during the assembly of the top base.
  • the fold line 61 is not offset, like in the traditional flap 21, but is aligned with the cuts 65 and 63. In this way, the closure of the box in this extremity is entrusted to the joint between the tongue 49 and the slot 55 of the flap 39.
  • the die-cut blank is made to assume a tubular condition by gluing the edge 4 to the inside of the portion 3.
  • the box is still flat and is kept flat up to the moment of packing, when it is erected and formed in a known way by folding the lower base up and superimposing the flap 21 and the wings 19 and 17; preferably flap and wings are glued to give a permanent closure.
  • the free extremity of the wing 43 is glued in the zone 43a to the inside surface of the portion 5, in this way affords the tongue 5 projects elastically toward the lower part inside the tubular body.
  • the fold 44 and the partial cuts 57 and 59 also favour the position engaged by the tongue.
  • the product for instance a bottle, is introduced into the box from the top, then the wings 41, 45 are folded toward the interior of the tubular body.
  • the converging fold lines 67, 69 facilitate closure of the box.
  • a small pressure on the top flap directed towards the interior of the box causes the flap to bend slightly downwards. This causes the slot 55 to sink further to hook the tongue 49 more easily.
  • the flap recovers its former shape as soon as this pressure is removed.
  • the user When, to open the box, the user lifts the flap 39, the effort is transmitted the tongue 49 and the opening causes the partial separation of the tongue 49 from the flap 43 along the lines outlined 49a.
  • the tongue 49 remains attached to the box only along the fold line 44 and remains lifted toward the top; the only resistance to opening is given by the tongue-slot engagement since, as said, there is no teeth-half cuts joint in the upper base like that in the lower base. This allows easier sizing of the length of the lines 49a so that the tongue tears along 49a on the application of a certain strength (fig. 3).
  • the flap 39 In the case that the flap 39 is equipped with the break-off lines 51, 53, they will break as well as the tongue in the zone indicated by the lines 49a. In this embodiment, because the box is closed again after it has been opened the first time, the flap 39 needs to be pushed toward the interior until it engages under the (broken) tongue 49, i.e. until the tongue rises above the flap (Fig. 4). Obviously, this can also happen if there is only partial breaking of the tongue.
  • the box allows to the user to see if it has been previously opened. As mentioned above, the cuts 63 and 65 are not able to engage the teeth 71 and 73 and the closure of the box, after the first opening, is entrusted to the tongue alone.
