Definitions

  • the container of the invention is usefully applied in particular, but not only, for containing foodstuffs and the like; given its characteristics, the container is suitable for use both domestically and commercially.
  • Soft bags however exhibit the typical drawbacks of non-rigid containers: for example, they do not offer adequate protection to the products they contain, especially if these products, for example fruit or vegetables, are easily perishable. Bags do not enable perishables to be stacked tidily therein, and they also do not afford easy access to their contents. Also, they have the drawback of being fairly unstable when placed on chairs or in the boot of a vehicle, and break easily when the products contained therein are bulky.
  • the main aim of the present invention is to provide a container which is reusable, which solves the problems exhibits by flexible containers and which occupies a limited space when not in use.
  • An advantage of the invention is that it provides a container which is easy and economical to realise, despatch and stock.
  • a further advantage of the invention is that it provides, when needed, a big space for containing goods.
  • a further advantage of the invention is that it provides a container which is easily transportable by hand by a user.
  • the container 2 of the invention is realised from a blank 1 which is flat and made of a cardboard sheet, covered in plastic, or a plastic sheet or other materials, of known type and suitable for the purpose.
  • a sheet of cellular polypropylene is used, as this type of material, apart from being considerably flexible and resistant, can be easily heat-welded with considerable advantages both during construction of the container and, as will better emerge herein below, during the phases of its use and re-use.
  • cellular polypropylene sheets are used which have a thickness comprised between 5 and 8 millimetres.
  • the container has a parallelpiped shape which is superiorly open and defined by a bottom wall 50 and lateral walls 51, 52, 53, 54 and 55 of rectangular shape.
  • all the walls are of the same height and opposite walls 53 and 54 (long walls) are longer than opposite walls 51 and 52 (short walls).
  • the external dimensions of the container can be various; a preferred embodiment is a parallelepiped container of size 50x30x25 cm, but this is in no way a constraint on size.
  • the scored blank 1 comprises external cut-lines which define the shape of the flat blank.
  • the blank also includes scored fold-lines 11, 12, 13, 14, along which the blank is folded when the container is to be assembled, so that is assumes the parallelpiped shape of the container.
  • the internal fold lines connect a part of the blank destined to define the bottom wall 50 of the container with the parts of the blank that are destined to define the four lateral walls 51, 52, 53, 54.
  • the blank 1 comprises four connection flaps 61, 62, 63, 64, each of which is connected to one of the sides of the opposite two lateral walls 51 and 52, precisely to the short walls of the blank 1, i.e. it is made together with the same lateral wall from which it is divided by a fold line.
  • connection flaps 61, 62, 63, 64 are folded on the adjacent side of the remaining lateral walls 52 and 54, to which they are solidly connected in order to obtain a parallelepiped shape which is no longer openable.
  • This type of connection flap which can obviously be alternatively connected to the long walls of the blank 1, are in common use in blanks 1 used for making parallelepiped packaging.
  • the blank 1 further comprises four reinforcement flaps 41, 42, 43, 44, each of which is connected to one of the lateral walls 51, 52, 53 and 54 on the opposite side to the side in which each lateral wall is connected to the bottom wall 50, i.e. on the upper free side of each lateral wall.
  • each reinforcement flap is made on the same lateral wall from which it is separated by a fold line.
  • each reinforcement flap is folded and solidly connected as a reinforcement on the external edge of the relative lateral wall.
  • the blank 1 also comprises a halfway fold line 3 which crosses the whole blank 1 in the direction of the larger side of the bottom wall 50.
  • the blank 1 also comprises four fold lines 31, 32, 33, 34 which are inclined by 45° and which each depart from a corner of the bottom wall 50 and terminate at the halfway fold line 3. These inclined fold lines 31, 32, 33, 34 intersect the halfway fold line 3 at a distance from the side of the bottom wall 50 which is equal to half the length of the lateral wall connected to the side. In figure 1 these fold lines, which are normal fold lines, have been evidenced using a thicker line to distinguish them from the others.
  • the container further comprises means for gripping, of known type, which have the function of enabling the container to be easily lifted.
  • the means for gripping are connected to the container or are afforded therein in proximity of reinforcements exhibited on the external side of each lateral wall.
  • At least a pair of slots are afforded in the opposite lateral walls 53 and 54; preferably two pairs of slots are afforded, respectively 71a, 71b, 72a, 72b.
  • Each slot is afforded, on the relative lateral wall, at a distance from the free edge of the lateral wall (i.e. from the opposite edge to the edge connected to the bottom wall 50) which is at least equal to the width of the relative reinforcement flap 43, 44; the slots of each pair of slots are basically cuts made parallel to the fold line 3 and are preferably afforded in a straight direction which is perpendicular to the fold line 3.
  • Each pair of slots is equipped with a handle, respectively 71 and 72, which is realised with a ribbon of flexible material; after the formation of the container, each of the ends of a handle is threaded into a slot and is folded upon itself so that it is wound around the reinforcement located superiorly of the slot.
  • a plastic material is used in order that the folded edges of the belt can be welded by heat-welding, thus fixing the ribbon about the reinforcement.
  • the lateral short walls 51 and 52 afford a pair of openings 73 and 74 cut into the walls with a closed cut line, the parts defined internally of the wall being thrown away.
  • the dimensions of these openings are such as to enable the fingers of hands to be inserted into them.
  • the openings 73 and 74 are made at a distance from the upper edge of the wall (i.e. the opposite edge to the edge connected to the bottom wall 50) which is at least equal to the width of the relative reinforcement flap 41 and 42.
  • a parallelpiped container 2 is formed with an open top, suitable for containing a considerable quantity of goods which are protected by the rigid walls of the container.
  • the container can be easily gripped either by insertion of the hands into the slots 73 and 74, or by gripping the handles 71 and 72.
  • the container completely and stably formed, can however be compacted down to reduce its overall volume if, for example, it is to be transported or stocked.
  • the first phase of which is illustrated in figure 3 it is sufficient to exert a slight pressure from outside on the bottom wall 50 and the short lateral walls.
  • the short walls will fold inwardly along the fold line 3, while the fold lines 31, 32, 33 and 34 will fold towards the inside, creating, on the bottom wall 50, two opposite recesses internally of which the lateral walls 51 and 52 fold and fall.
  • the handles 71 and 72 can easily be contained internally of the folded container.
  • the folded container assumes a volume which is a parallelepiped, with the base thereof equal to a long lateral wall, having a thickness which is about the same as four times the thickness of the sheet of material the blank is made of.
  • the thickness of the compacted container is about 2.5 or 3 centimetres, compared with the open container size of about 20-30 cm; the compacted container is therefore reduced tenfold in size. Obviously these proportions vary according to the thickness of the blank sheet used and the external dimensions which are required for the container.
  • the main if not the only use of the container is to replace and improve on the "classic" plastic shopping bag usually provided by supermarkets and used for shopping.
  • the user receives a container which has the functionality of a box, and even has handles for its transportation. Once used, the container, differently to a normal box, be compacted down and stored, having a very small volume.
  • Another considerable advantage is that the bottom of the container is formed by a single element, and not parts which are glued together or jointed. The bottom is also connected to the external walls without any gluing, which makes the whole container more sturdy as breakages in its lower parts are unlikely.
  • the material preferably used i.e. cellular polypropylene, has advantages during the making of the box but is also notably resistant even after much folding, so it is possible to refold it many times along lines 3, 31, 32, 33, 34, which therefore behave like as series of hinges which the walls or container parts are rotated.
  • the box can therefore be used many times over, without the material used in its manufacture breaking or getting damaged.
