Definitions

  • This invention relates to a box of the type used to pack fragile articles, and particularly, but not exclusively to a box for packing lithographic printing plates.
  • Lithographic printing plates are generally rectangular or square in shape, and very thin in cross-section. When packing such plates for transit, it is important to ensure that the plates cannot become damaged.
  • a problem with this known box is that the process of fitting the polystyrene pieces into the box is time consuming, and therefore expensive.
  • the polystyrene is harmful to the environment in that it is not recyclable.
  • a box adapted to receive articles for storage or transit, the box comprising: a box forming blank comprising a base portion defined by a first pair of oppositely disposed fold lines, and a second pair of oppositely disposed fold lines, a first pair of flaps extending from the first pair of fold lines respectively, and a second pair of flaps extending from the second pair of fold lines respectively; a retaining insert for retaining the one or more articles, which insert is shaped to be attachable to the base portion of the blank.
  • An object to be stored or transported for example one or more lithographic printing plates may thus be placed within the area defining the base portion of the box forming blank.
  • the retaining inserts may be placed over the article and fixed to the base portion towards the fold lines defining the base portion. The retaining insert ensures that the article cannot move within the box.
  • both the box forming blank and the retaining insert may be made of cardboard. As such the process of packing and forming the box is more easily automated, and in addition the box is recyclable. A further problem is that the process of assembling and packing the box is not. easily automated.
  • the box according to the present invention is particularly applicable to transport or storage of fragile articles which are relatively thin in cross section and have a substantially square or rectangular shape.
  • the retaining insert is substantially cross shaped having a central portion and two pairs of oppositely disposed flaps extending from the central portion.
  • One or more lithographic printing plates to be packed in the box may be placed substantially centrally on the box forming blank, within the base portion, which base portion is preferably shaped to be larger than the shape of the plate.
  • the retaining portion may then be placed over the plate and attached to the base portion of the blank by means of adhesive applied to the flaps of the retaining insert *
  • each of the flaps of the retaining insert comprises two parallel folds extending parallel to the extreme edge of each flap, which folds are positioned to correspond with the thickness of the plates being packed in the box. These folds may be pre-formed or may be formed during the process of attaching the retaining inserts to the blank when the plates are in place.
  • the retaining insert comprises a bottom layer and a top layer.
  • the article to be packed is positionable o the bottom layer, and the top layer is then positionable ove the article and attachable to the bottom layer along the edge of each layer.
  • the two layers may be attached together by an convenient means for example by means of adhesive, bu preferably they are attached together by means of a threa which is sewn around the edges of the layers thus completel enclosing the object within the layers.
  • the bottom layer of the insert may then be attached to the bas portion of the box forming blank by any convenient means, b for example means of adhesive.
  • the advantage of forming the retaining insert from a doubl layer in this manner adds further protection to the object, and also reduces problems due to delamination of the cardboar used for the different components forming the box.
  • each of the flaps of the box forming blan comprises a second fold line parallel to the first fold line, and spaced apart from the fold line to define the thickness o the complete box.
  • the second fold lines may be pre-formed o formed during the process of assembling the box.
  • first pair of flaps of the blank are deeper, and thus extend further out from the central portion than th second pair of flaps.
  • the depth of each of the second pair o flaps will thus form a side wall of the finished box, whereas the first pair of flaps is sufficient to form a side wall, an also to extent to form a portion of a top surface of the box.
  • Each of the blank flaps thus comprises a portion defined between the two parallel fold lines which portion defines the thickness of the side walls of the box, and an edge portion extending from the second fold line to the edge of the flap.
  • the two second flaps of the blank are positioned to define the thickness of the side walls, and the edge portions of each flap are folded over.
  • a first of the first pair of flaps is folded such that the edge portion extends over the two edge portions of the second pair of flaps.
  • the edge portion of this first flap of a first pair of flaps may be attached to the edge portions of each of the second pair of flaps.
  • the remaining flap of the first pair of flaps may be folded over and attached to all three of the other flaps. This final flap forms the opening flap, and in use is separated from the remainder of the box in order to gain access to the box.
  • the retaining insert comprises a drawstring extending substantially parallel to the fold lines of the opening flap of the blank.
  • the drawstring is used to detach one of the flaps of the retaining insert from the remainder of the retaining insert. It is then possible to remove the plates from within the retaining insert.
  • An advantage of the box according to the present invention is that although the opening lap is detached from the remains of the box, and one of the flaps of the retaining insert is detached from the rest of the retaining insert, the remainder of the box remains intact, and can be used to store the plates after delivery.
  • the retaining means is attached to the blank by means of hot melt adhesive.
  • a range of different sizes and/or numbers of plates may be accommodated in a particular size of box.
  • box forming blank may be made in a number of different sizes, with the retaining insert made in a corresponding number of compatible sizes. This further increases the range of different sizes and numbers of plates which may be packed in a box according to the present invention.

  • the box forming blank comprises a base portion 12 which is defined by top and bottom fold lines 13, 14 and side folds 15, 16.
  • the blank 11 further comprises a first pair of side flaps 17, 18 and a second pair of side flaps 19, 20.
  • the base portion 12 has a generally rectangular shape and side flaps 17, 18 extend along the long lengths of the base portion 12, whereas side flaps 19, 20 extend along the short length of the base portion 12.
  • Each side flap 17, 18, 19, 20 comprises a second fold line 21, 22, 23, 24 each of which extend substantially parallel to the first fold line 15, 16, 17, 18 respectively.
  • the distance between the two fold lines defines the thickness of the box when assembled.
  • each side flap comprises a further pair of fold lines 25, 26 extending substantially parallel to the fold lines 15, 16. These fold lines are used to add strength to the box as will be described later.
  • the box 10 comprises a box forming blank 11.
  • the box forming blank comprises a
  • retaining insert 27 which is generally cross shaped comprising a central portion 28 and flaps 29, 30, 31, 32.
  • one or more lithographic printing plates 33 are positioned substantially centrally within the base portion 12 of the blank 11.
  • the box will be used to hold a pack of plates, containing a plurality of lithographic printing plates.
  • the fold lines 15, 16, 25, 26 in the blank are positioned substantially centrally within the base portion 12 of the blank 11.
  • the retaining insert 28 is then placed over the plates 33.
  • the size of the insert 28 is chosen to correspond with the size of the base portion 12.
  • Hot melt glue is applied to the base portion 12 in a position corresponding to the position of the flaps 29, 30, 31, 32 of the insert 28.
  • the flaps 29 to 32 are then pressed down to adhere to the base portion 12.
  • fold lines 35, 36 are formed which define the thickness of the plates 33. Alternatively, the fold lines 35, 36 could be pre-formed.
  • side flaps 19, 20 are first of all folded into position as will be described in more detail later.
  • the flap 18 is then folded over the two flaps 19, 20, and finally flap 17 is folded over all three flaps.
  • Flap 17 may be secured to the remaining flaps by means of an adhesive tape (see Figure 6) .
  • flap 17 is detached from the remains of the box to allow access to the inside of the box.
  • the flap 29 of insert 28 comprises a drawstring 37.
