Definitions

  • the invention relates to a method of packaging a convex body, or equivalent convex volume circumscribed to any body, produced from a thin film.
  • the packaging, object of the invention is produced in a preferred version from a rectangular sheet of length L and width K.
  • Figure 1 shows a fold formed by symmetrical folds.
  • FIG. 2 represents the previous folding, the ends of which have been fixed.
  • FIG. 3 represents a folding of the type Fig. 1 carried out on a sheet one side of which has been folded longitudinally to form a double thickness of film.
  • FIG. 4 represents the folding of FIG. 3, an angle of which has been entered in the zone where there are two thicknesses of film.
  • FIG. 5 represents the folding of FIG. 3 deployed to obtain a change of direction of the folds according to the invention.
  • FIG. 6 represents a package according to the invention comprising two changes of direction.
  • Figure 7 shows a package according to the invention deployed around an object.
  • FIG. 8 represents a method of fixing the folds by adding a flexible tape.
  • the packaging is in the form of a parallelepiped (fig. 2) of length K, width A and thickness 6 corresponding to the number of N folds; the thickness 6, of the folds to be fixed at their ends 7 and 8, is directly proportional to the number N of folds; the fixing techniques must be adapted according to the uses to be made of them and the number N of folds.
  • the folds are attached to the ends in various ways; first there are the methods of fixing sheets to each other, from binding, such as stapling, pinching, sewing, gluing on the edge, the use of a ring passing through a hole made with a cookie cutter, this list not being exhaustive; then there are the high frequency, ultrasonic, thermal welding methods of films that can be welded or made weldable by depositing a layer of plastic material or single-sided or double-sided heat-activated adhesive, this list not being exhaustive.
  • the attachment may concern the entire width A of the ends 6 and 7 of the plies and the two sides of the film.
  • each fold fixing zone is then separated from the next by a strip of film of width A; it constitutes a border making it possible to improve the aesthetics of the whole; however, it should not be forgotten that the fasteners thus produced work on peeling during deployment of the packaging, that the fixing remains fragile and that the packaging can be prematurely damaged.
  • the maximum number of folds tolerated depends on their method of fixing their ends and it may vary significantly.
  • the deployment of the central part of the packaging, as it is produced, does not allow the ends to systematically fold back towards the center of the upper and lower parts of the object to be packaged; folds that are usually quite wide have trouble deploying to cover the top and bottom surfaces.
  • One way to facilitate this deployment consists, by appropriate folding, in giving the folded packaging a more complex shape (fig. 6); one way to do this is to try to obtain folds, no longer made up of flat rectangular bands 1 (fig. 1) but of rectangular bands 9 (fig. 6) folded on themselves so as to give them a direction chosen in advance ; for example, we can give the folded packaging (fig.
  • One way of making this kind of folding manually with a change of direction is to first define strips of width A and length K (fig. 3); to fold the end 20 longitudinally whose direction you want to change, and to perform the folding as described above of the rectangles 1 (fig. 1) one side of which 20 (fig. 3) has two thicknesses of film with a folding edge 23. Then we enter each angle 22 of the folds obtained to mark the oblique line 24 (fig.4) which will allow each strip 1 to fold back on itself; once the edges are well marked, unfold the previous fold (fig.4) and put in place the following folds the creases made (fig. 5); all that remains is to fold the folds over each other and fix the ends as shown (fig. 6).
  • FIG. 8 represents a method of fixing the pleats or of reinforcing their fixing by adding a flexible tape.
  • This flexible tape 26 (fig.8) is fixed by welding or gluing and avoids the work of peeling the fixing of the folds in the vicinity of the edge 13 when it only interests one side of the film; the strip alone can constitute a method of fixing the folds.

Claims (10)

  1. Verpackung aus einem dünnen, gefalteten Blatt für Gegenstände mit konvexer oder ähnlicher Form, dadurch gekennzeichnet, daß sie durch Faltung des Blattes zur Bildung von identischen rechteckigen Streifen (1), von Parallelogrammen oder von gleichschenkligen Trapezen gebildet wird, wobei jeweils zwei davon bei beliebiger Form in Bezug auf die gemeinsame Faltkante (4) symmetrisch sind, genau aufeinanderpassen und an mindestens einem Ende aneinander befestigt sind.
  2. Verpackung nach Patentanspruch 1, dadurch gekennzeichnet, daß die Richtung der Faltung durch Umfalten der Streifen entsprechend einer schräg verlaufenden Linie (12) verändert wird, sodaß die Innenkanten (10) zu Außenkanten (14) und die Außenkanten (11) zu Innenkanten (13) werden.
  3. Verpackung nach Patentanspruch 2, dadurch gekennzeichnet, daß die beiden Enden (16) und (17) der die Falten bildenden Streifen die Richtung ändern, sodaß bei zusammengefalteter Verpackung ein U gebildet wird, das dem Halbprofil des zu verpackenden Gegenstandes weitestgehend entspricht, sodaß die Falten beim Auffalten der Verpackung um den zu verpackenden Gegenstand herum eine ästhetische Form behalten.
  4. Verpackung nach Patentanspruch 2 und 3, dadurch gekennzeichnet, daß die Richtungsänderung der Falten von Hand durch vorherige Längsfaltung eines Streifens (20) entlang einer Kante (23) des ursprünglichen Papierbogens vor dem Umfalten in symmetrische Falten und anschließendes Eindrücken der Ecken (22) zur Markierung der schräg verlaufenden Linien (24) vor dem Auffalten erfolgen kann, sodaß die Innenkanten (10) zu Außenkanten (14) und die Außenkanten (11) zu Innenkanten (13) werden.
  5. Verpackung nach einem der obengenannten Patentansprüche, dadurch gekennzeichnet, daß die Falten eine oder mehrere ähnliche oder unterschiedliche Richtungsänderungen erfahren.
  6. Verpackung nach einem der obengenannten Patentansprüche, dadurch gekennzeichnet, daß die Befestigung der Enden durch Techniken des Buchbindens bzw. Brochierens oder durch Techniken des Warmschweißens von Kunststoff bzw. thermoaktivierbarem Klebstoff erfolgt.
  7. Verpackung nach einem der obengenannten Patentansprüche, dadurch gekennzeichnet, daß die Befestigung der Enden durch Befestigen der Enden der die Falten bildenden Streifen erfolgt.
  8. Verpackung nach Patentanspruch 1 bis 7, dadurch gekennzeichnet, daß die Befestigung der Enden nur auf einer Blattseite erfolgt, sodaß jeweils zwei über eine Faltkante (4) miteinander verbundene aufeinanderfolgende und so die Falte bildende Streifen an ihren Enden aneinander befestigt sind, jedoch zwei aufeinanderfolgende Falten untereinander nur durch die Faltkante (5) verbunden sind.
  9. Verpackung nach Patentanspruch 8, dadurch gekennzeichnet, daß die über die Kante (4) erfolgende Befestigung der Enden der Falten nur auf einem Teil der Breite der Faltenstreifen erfolgt und der auf der Seite der Kante (5) befindliche Streifenteil keine Verklebung erfährt und somit eine teilweise Umgruppierung der Falten möglich ist.
  10. Verpackung nach Patentanspruch 9, dadurch gekennzeichnet, daß die Befestigung der Enden durch ein flexibles Band (26) verstärkt wird, das gegebenenfalls auch allein zur Befestigung der Enden der Streifen verwendet werden kann.
