Definitions

  • the invention relates to the field of packaging made of cardboard or other semi-rigid material. It relates in particular to a packaging of the type comprising a part with four panels forming a belt and at least one part constituting a bottom wall.
  • the packaging known as American crates is widely used for the storage and transportation of everyday consumer items.
  • the crates include a belt with four panels and two walls, one lower and the other upper. The latter are produced, after shaping the belt, by folding flaps which extend the four panels of the belt. More precisely, glue blocks are deposited on the external face of two opposite flaps, they are folded at 90 ° and then the other two flaps are folded on the first. Thus the four flaps are joined together two by two, one inside the other outside, and form the bottom wall. After loading, the box is closed in the same way. It is certain that these operations can be automated.
  • the box After use, the box is dismantled to facilitate its storage and evacuation with a view to its destruction or recycling of the cardboard, if necessary.
  • the number of cases that staff have to handle can be very large. It is therefore desirable to provide a means allowing these cases to be easily flattened out after they have been emptied of their contents.
  • the present invention proposes to solve this problem.
  • a cardboard or other semi-rigid material of the type comprising four walls forming a belt and at least one bottom wall formed by two parallel inner flaps and two parallel outer flaps joined together in pairs, one inside the other outside, by fastening means, characterized in that the bottom wall comprises a means of folding along a diagonal and two means for separating the inner flaps from the outer flaps on either side of the so-called diagonal.
  • Such packaging can be easily flattened thanks to the combined implementation of the means under the action of a simple pressure exerted on the bottom wall inward.
  • the means for attaching the flaps to each other preferably consist of blocks of glue, in particular hotmelt glue, applied hot by means of applicator guns.
  • the folding means consists, for example, of an alternating cut made on at least one of the outer flaps from one of the corners of the bottom.
  • the folding axis thus formed has the function of facilitating the scissors coming together of the two walls forming the said angle.
  • the folding is made even easier if an alternate cutting is provided on the inner flap parallel to that of the outer flap. Alternate cutting is preferred to simple creasing because it allows more efficient folding. Creasing is not to be excluded, however.
  • the means for separating the inner flaps from the outer flaps on each side of the diagonal are preferably constituted by pre-cuts delimiting a detachable portion of the inner flaps. This portion includes the attachment means between the inner flap and the corresponding outer flap. Thus, it facilitates the opening of the angle formed by the two walls located on the same side of the diagonal.
  • a particular advantage of the solution of the invention is that it does not modify the cutting of the cardboard.
  • the user can volume this packaging like a traditional packaging without having to modify his training facility and closing the flaps.
  • FIG. 1 a plate 1 of cardboard or other equivalent material, cut and grooved to form an American box.
  • the plate 1 comprises, as is well known, panels 2, 4, 6, 8, delimited by the respective grooves 21, 24, 46, 68 (shown by broken lines) and the edge 85, as well as a stud 3 between the creasing 21 and the edge.
  • the panels 2, 4, 6, 8 are extended respectively by panels 21, 22, 41, 42, 61, 62, 81, and 83.
  • the belt is first formed by folding the panels around the grooves and fixing the post 3 to the panel 8 along the edge 85, by gluing or stapling.
  • the panels 22 and 62 which constitute then the interior flaps.
  • Glue is deposited on these two flaps, for example two blocks of hotmelt glue, each in an area close to the free angles. Then fold the other two flaps, keeping them pressed against the first two until the glue hardens.
  • the flaps 42, 82 constitute the outer flaps.
  • the adhesive pavers constitute the means for attaching the flaps together.
  • the flaps are joined in pairs, that is to say an inner flap with an outer flap. There are thus four connections: 22/42, 22/82, 62/42 and 62/82.
  • a preferential folding means has been provided for the outer flap 42.
  • This consists of an alternating straight cut 43 of the flap 42, traced from the angle adjacent to the creasing 24 to its free edge.
  • precut or alternate cutting is meant cutting the plate along a succession of segments separated by uncut areas and constituting tenons or attachment points. In the case of alternating cutting, the attachment points are longer than in the precut.
  • This cut 43 forms an angle alpha with the edge of the flap located in the extension of the creasing 24. This angle is for example 45 ° but it can deviate substantially.
  • a second alternating cut 83 identical to the first, has been provided on the flap 82 which is not adjacent to the flap 42.
  • This precut forms the same angle alpha with the edge of the flap 82 situated in alignment with the creasing 68.
  • two alternate cuts are also provided, 23 'and 63' respectively, on the flaps 22 and 62. They form an alpha angle with the creasing delimiting their respective flap
  • a means 23 for separating the flaps 22 and 82 and a means 63 for separating the flaps 62 and 42 have also been provided. These means 23 and 63 are formed by precuts which delimit a portion, 25 and 65 respectively, capable of being detached from the flap. This portion extends over the flap, 22 resp. 62, so that the attachment means, 22/82 resp. 62/42, that is to say included in the zone thus delimited.
  • FIG. 2 shows the body turned over so as to see the bottom wall.
  • the inner flaps 22 and 62 are visible by transparency.
  • auxiliary grooves 26, 46, 66, 86 can be provided.
  • FIG. 3 There is shown in FIG. 3 a cardboard plate allowing the production of a display packaging as described in patent application EP 93402026.
  • This plate has the advantage of being able to be set in volume in the same way as an ordinary American fund.
  • the present invention is advantageously applied to part I of the box which constitutes the cover of the packaging. This can be flattened after being detached from the portion II forming a display tray.
