Definitions

• Pleated packaging with a fold-free area that can be brought back Pleated packaging with a fold-free area that can be brought back.
• the invention relates to packaging for objects of convex or similar shape and obtained from a pleated thin film, such as those described in patent FR 86 03956, certificate of addition FR 88 03654 and patent FR 90 13589.
• Figure 1 shows a package according to the invention fixed leather against flesh.
• FIG. 2 shows the packaging according to the invention during assembly on a hamburger.
• Figure 3 shows a package according to the invention set up on a hamburger.
• FIG. 4 represents a package according to the invention, the non-pleated part of which is made of the same film as that used to make the folds with a "TACO" in the packaging position.
• FIG. 5 represents a "TACO" during packaging.
• Figure 6 shows a packaged "TACO”.
• FIG. 7 shows a package according to the invention after fixing the crease-free zone by flesh-to-flesh fixation.
• Figure 8 shows the same packaging in the use position.
• FIG. 9 shows a package according to the invention provided with a semi-rigid reinforcing strip.
• Figure 10 is an exploded view of a hamburger to see how the reinforcing strip is placed between the deployed film and the hamburger.
• FIG. 11 shows a variant of the invention in which a reinforcing strip and a fold-free zone are used simultaneously to cover the zones not covered by the pleated part of the packaging when it is deployed.
• a crease-free zone 1 (Fig.l) generally consisting of a thin film or a semi-rigid thin material depending on the perfor ⁇ mance sought; the fold-free zone 1 is either a product attached and fixed by any means compatible with the pleated film, or an enlarged fold-free zone 2 (FIG. 4) integrated as an element of the pleating as described in the cited patents.
• the length 3 (Fig.l) and the width 4 of the fold-free zone 1 is determined on a case-by-case basis depending on the product to be packaged; as regards a package for the "TACO" 6 (FIG. 4), it is given substantially the length 5 of the rectilinear zone corresponding approximately to the diameter of the circular pancake; as for the width 7 it can be less than the spacing 8 of the zones fixing the folds of the pleated area; in a preferred version of the invention, the fold-free zone 9 is obtained by widening the fold-free zone produced to allow the packaging to be separated from one another according to the cited patents.
• this fold-free zone may consist of an attached sheet 1a (Fig.l) fixed to the end 14 of the package 13 pleated according to the cited patents; in the case " where, for example, the film used is a polyethylene paper complex, the reported fold-free zone 1 is itself made up of polyethylene paper complex; the polyethylene face 15 of the reported fold-free zone 1 is fixed, on the edge 14 of the pleated packaging 13, either on the paper side 16 (Fig. 2), or on the polyethylene side 17 (Fig. 8) of the pleated packaging 13; when it is attached to the paper side (Fig.
• the crease-free zone 1 is positioned at the time of the seal so as to be in its final position so that the polyethylene part 15 is on the side of the product to be packaged; if the seal is made flesh against flesh the area without folds 1 (Fig. 7) attached is at the time of the welding above the pleated area 13 of the packaging and it will suffice to turn it over (Fig. 8) to obtain that the area supporting the polyethylene 15 in the crease-free zone 1 is turned towards the side of the product to be packaged r.
• a cardboard 18 (Fig. 9) of width 19 substantially equal to the height 20 (Fig. 10) of hamburger 24 and length 21 between, for example, the half-perimeter of the hamburger and the complete perimeter in a section perpendicular to its axis of symmetry 22;
• the cardboard box 18 (FIG. 9) can be, for example, made up of a polyethylene cardboard complex and fixed by a flesh-to-flesh seal, at the end 14 of the pleated part of the packaging; as in the previous case, the cardboard box 18 is positioned above the pleated zone 13 of the pleated packaging, but there is no reversal as before to allow the cardboard box 18 (Fig.
• the film when deployed around the hamburger 24 is shaped and maintains the cardboard 18 which does not need to completely surround the hamburger 24 and to be locked on itself to provide a vertical load holding function; this cardboard also constitutes a thermal barrier limiting the cooling of the packaged hamburger and may include an aluirq-nized face to further improve this insulation effect.
