Definitions

  • the present invention relates to a packaging for packaging batches of objects having different volumes. It also relates to a method of manufacturing such packaging.
  • French patent N ° 2498561 proposed to cover the full tray with a cardboard or corrugated element with a U-section, the parts corresponding to the branches of the U have a height equal to that of the highest walls of the tray.
  • the cost of such packages is moderate, but their resistance to vertical compression remains unimportant, which affects the stacking of full packages.
  • the products to be packaged can only have a relatively moderate weight, because, in the event of a fall or a violent impact on the packaging, there are significant risks of detachment of the plastic film. and packaging at the bonding points.
  • the present invention relates to cardboard or corrugated cardboard packaging, in particular American boxes of the type in which a film of heat-shrinkable plastic material is secured to the bottom part.
  • the invention more specifically aims to strengthen the assembly of the film and the packaging, while proposing an assembly capable of being produced at high speed and, consequently, of low cost, which is capable of being filled and mechanically closed, regardless of the volume of the batch of objects to be packaged.
  • the subject of the invention is a packaging for packaging batches of objects of different volumes, of the type comprising an American box or the like and a film of heat-shrinkable plastic material secured to the bottom of the box, characterized in that the plastic film is pinched between the outer flaps, adjoining two parallel walls of the box and constituting the bottom proper of the package, and the inner flaps, adjoining the other two walls and lining this bottom internally.
  • the heat-shrinkable e film Due to the fact that it is trapped between the bottom and the interior flaps of the box, on which the conditioned objects rest, the heat-shrinkable e film will not risk accidentally detaching from the packaging, especially since after thermore- traction, it will tightly grip the inner flaps. This produces a much more reliable packaging than those in which one or more plastic films are glued against the bottom or against the side walls of the American box.
  • flaps will preferably be joined, but the choice of the precise type of packaging in cardboard or corrugated cardboard will depend on the nature and volume of the products packaged, since a relatively large object, resting on both flaps at the same time, will not require adjoining flaps.
  • the packaging will be formed at its lower part (outer flaps at the bottom of the American body) and at its upper part (outer flaps at the upper face), using adhesive or gummed tape. Bonding can be carried out using “Hot Melt” or cold glue.
  • the packaging according to the invention can be produced by various methods. Advantageously, however, the following process can be used, which constitutes another object of the invention.
  • This process is characterized in that, the packaging being open at its upper part and at its lower part, the film of heat-shrinkable plastic material, unwound from a reel using a drive means, is lowered inside the package using a piston or the like, parallel to two opposite side walls, until it exceeds the free edge of the flaps, in that the two flaps adjoining the other two side walls , preferably those having the smallest width, are then folded towards the inside of the packaging perpendicular to the adjoining walls and are optionally glued in spots on their external face, in that the film is then brought back into contact with the external face.
  • previously folded flaps in that the other two flaps are folded in turn and applied against the outer face of said film, and in that the latter is cut laterally, so as to define parts intended to be folded back nt on conditioned objects, prior to shrinking the plastic film.
  • Figures 5 to 8 are schematic vertical sections illustrating a mechanization of this process.
  • the packaging in accordance with the invention comprises an American box 1 and a film of heat-shrinkable plastic 2.
  • This film is pinched between the bottom proper of the box, constituted by the external flaps 3 adjoining the side walls 4 (preferably the widest), these flaps 3 being assembled together by an adhesive tape not shown, and the internal flaps 5, adjoining the side walls 6 of the body.
  • this packaging can be produced in a simple manner by introducing the film 2 inside the box 1, open at its two ends, with the flaps 3 and 5 arranged in the extension of the adjoining walls or deviating from the plane thereof towards the outside.
  • the film is introduced into the packaging with its two strands 2a, 2b applied to the internal face of the walls 4, until the part 2c joining the strands 2a and 2b exceeds the end of the flaps 3 and 5 (FIG. 1 ).
  • the flaps 5 are then folded at right angles towards the inside of the box (FIG. 3), then the two strands 2a, 2b of the film 2 are then reassembled along the walls 4 (FIG.
  • flaps 3 are then folded perpendicular to the walls 4 (FIG. 1) and assembled together by means of an adhesive strip, so that the film 2 is firmly pinched between the flaps 3 and 5, with the advantages which will result therefrom, c that is to say the elimination of the risks of separation of the film 2 and of the body.
  • the film may possibly be made integral, for example by collage, shutters 3 or, preferably, shutters 5.
  • FIGS 5 to 8 illustrate in schematic form a simple mechanism for implementing the method which has just been described.
  • the film 2 is unwound below the piston 11 from a reel 12, passing over relay rollers such as 13, using a clamp 14 controlled by a jack 15.
  • a counterweight 16 exerts on the film 2 a pull, against the jack 15.
  • the upper flaps of the American box will preferably be applied laterally against the external face of the side walls, as shown in the figure. 7.
  • two adjoining flaps with two contiguous side walls may advantageously, in a manner known per se, be integral with one another at their free edge, the cut which separates them not extending up to at this edge. The case being flattened, the flaps are applied against the side faces and the box is then opened.
  • the piston 11 is then introduced into the box 1 (FIG. 6) by pushing the film 2 inside of it, until it exceeds the lower end of the lower flaps 3 and 5.
  • the two strands of the film 2 which protrude from the lower part of the packaging are then separated from each other, for example using a system of suction cups 17 controlled by jacks 18, which will have for effect of spreading the flaps 3 from one another.
  • the flaps 5 are then folded towards the inside of the American box, perpendicular to the adjoining walls, using a system of pressing pads or the like and their external face is optionally glued (FIG. 8).
  • the action of the suction cups 17 is then eliminated, the piston 11 is raised to an intermediate stage and, by acting on the counterweight 16 (or using an auxiliary motor), the film 2 is also raised until its lower part comes into contact with the external face of the flaps 5 (FIG. 8), pressing pads 19 then fold the flaps 3 against the film 2.
  • the flaps 3 are then assembled using an adhesive tape or Hot Melt or cold bonding (not shown) and the film 2 is cut using a knife 20.
  • the products to be packaged are then placed in the packaging and the parts 2a and 2b of the heat-shrinkable film are folded over these products.
  • a pulsation of hot air is then sufficient to ensure the self-welding of the parts 2a and 2b and the retraction of the film.
