Definitions

  • the present invention relates to the packaging described in patents FR-A-2 595 666 and EP-A-0 333 605 and produced from a thin pleated sheet whose edges of the folds are fixed together by various means .
  • the folds are coated folds whose characteristics derive from the nature of the object to be packaged as well as the spacing of the welds. Said folds, being fixed on the edges, are free in the middle, so that their deposition constitutes a cavity capable of receiving a convex object.
  • These patents describe a method making it possible to obtain this type of shape from a flat sheet by making parallel coated folds which give the folded packaging a substantially planar shape which becomes volume by unfolding.
  • the object of the invention is to generalize this packaging process not only for sandwiches, but for all kinds of objects as diverse as dishes, pizzas, fruits, sanitary napkins, or beauty products.
  • Fig. 1 shows a cylindrical shape supporting a package according to the invention.
  • Fig. 2 partially shows a rectangular sheet before folding, on which the position of the folds and their orientation are shown.
  • Fig. 3 represents the folded packaging corresponding to the folds indicated in fiG. 2.
  • Fig.4 shows any convex volume capable of being packaged with a package according to the invention.
  • Fig. 5 shows a package where the folds are replaced by gathers located on the side edges.
  • Fig. 6 shows a package whose distance between the pleat fixing zones varies to facilitate the recovery of the package by itself in assembly course.
  • Fig.7 shows a detail of a method of strengthening the fixing of the folds by adding a band; this strip is shown widened towards the outside of the packaging to allow the filling of the uncovered area limited by the border of the folds.
  • Fig.8 shows a detail of a method of strengthening the fixing of the folds by folding their ends.
  • Fig. 9 shows a detail of the fold fixing area in which the folds have been extended to cover the area delimited by the fold fixing area.
  • Fig.10 shows a variant of the method of strengthening the fixing of the folds shown in Fig.7 in which the enlargement is made on the internal side then the band is turned over, after fixing to cover the area delimited by the area for fixing the folds.
  • Fig.11 shows a method of fixing the end of the folds as in Fig.8 but the width of the fold has been increased so that the end of the folds can be turned outwards to fill the area delimited by the pleat fixing area.
  • Fig.12 shows a method of fixing the folds combining the reversal of the end of the folds as shown in Fig.8 and the installation of an enlarged band inward as shown in Fig.10.
  • Fig.13 shows in section of the folds folded which do not overlap any more when one has "B ⁇ (A / 2)".
  • Fig.14 shows an object partially covered by the packaging according to the invention, so that the latter serves to grasp it, without, for example grasping it between the hands.
  • Fig.15 shows a sheet allowing to make a package according to the invention, and which has the shape of a parallelogram. As an example, a possible position of the folds has been presented.
  • Fig.17 shows a portion of a sheet allowing to make a packaging according to the invention, and which is constituted of two successive reference sectors "i" and "i + 1" whose characteristics differ. As an example, a possible position of the folds has been presented.
  • Fig.18 shows a method of filling the non-covered areas combining the solutions described in Fig.7 and Fig.10.
  • Fig. 19 shows one of the methods of fixing the folds by sewing.
  • Fig.20 shows a package according to the invention whose folds are fixed on one side.
  • the packaging is determined from the perimeter "P1" (3), obtained by the intersection with a plane perpendicular (5) to the axis of revolution (4) of the cylinder, which is equal to "pi * D" ( “pi” being the constant of the circle), of the perimeter "P2” which is obtained by the intersection of the cylinder with a plane (6) passing through the axis of revolution (4) of the cylinder, which is equal to “2 * (H + D) ";
  • this packaging must surround the cylindrical part of the object and then delimit on the upper and lower parts two zones (33) and (32) substantially circular in diameter "DS" (7) and "DI” (8) having the point at the center intersection of the axis (4) of the cylinder with the plane of the zones (33) and (32).
  • K the total width of the starting sheet before folding and fixing the folds
  • M the free width of the folds between the fixing zones which is measured from from the inner edge of the pleat fixing zones (15) and (16); the length of the edges "LI” and “LS” is taken at the inner edge of the areas for fixing the pleats (16) and (15).
  • the packaging Before unfolding, in the event that the folds (29) are substantially perpendicular to the fixing zones (15) and (16) of their ends, the packaging takes up substantially the form of a developed from a truncated cone of revolution whose diameters of the upper and lower circles are "DS" and "DI"; when the packaging is laid flat Fig.3, the folds fixing areas (15) and (16) then form two arcs of concentric circles; the folds (29) are no longer parallel to each other and converge towards a zone adjacent to the center (17) of the two arcs of concentric circles formed by the zones for fixing the folds (15) and (16).
  • the packaging Fig.6 is no longer formed by two concentric circles (15) and (16) Fig.3; the increase in spacing of the two fold attachment zones (30) and (31) Fig. 6 is between 5% and 15%; one way of proceeding may consist in giving the edge corresponding to the opening (32) Fig.1 the largest, the shape of a centrifugal Archimedes spiral (30) and the edge corresponding to the opening (33) the smaller the shape of a centripetal Archimedes' spiral (31); but there are many other ways to vary this spacing.
  • the object to be packaged has been defined as a cylinder of revolution to simplify the explanations; but it is possible to pack with this type of packaging all kinds of convex or non-convex objects; in the case where an object has concavities, it suffices to consider the smallest convex object capable of being circumscribed to said object having concavities; the smallest circumscribed convex object is considered to have the smallest volume; we then take the convex volume thus defined, which is a fictitious convex volume, to size the packaging; in the rest of this description we will only take into account convex volumes; to determine the axis (19) Fig.4 around which the packaging will be wrapped, it is known that it passes through the isobarycenter (20) of the convex volume; one can, if desired, choose any direction for this axis (19), and it will always be possible to determine a packaging; but it will not be optimized, in particular from the point of view of the sheet surface used; generally the choice is made empirically and it is dictated by common sense
  • the fixing of the folds can be carried out, for example, by a prior coating of the sheet, at least in the zones concerned by the fixing of the folds, and on at least one face, with a heat-sealable material;
  • a hot electrode of suitable shape and the faces coated with heat-sealable material located opposite are welded; if one is satisfied with this type of attachment, it may be that, for certain applications, the method of fixing the pleats is not not strong enough; in particular the welds work on the peeling and there is tearing off of the layer of heat-weldable material; in order to be able to reinforce them, it is possible to use a thin strip (34) Fig.7 correctly cut and fix it on the folds (51); the shape of this strip (34) is derived from the shape of the edges of the packaging; for example, in the case where the packaging is an involute of cone Fig.
  • the strip (34) Fig. 7 may itself be an involute of cone whose radius of the arcs of circles which limit it internally and externally frame the radius of the arc of a circle Fig.3 formed by the area for fixing the folds (15) or (16); if the packaging is a cylinder involute with parallel folds, this strip is also becomes a cylinder involute; such a strip becomes tensioned as soon as the folds are subjected to forces, and the fixing zones then work no longer on peeling, but on shearing; the strip (34) Fig.7 must be wide enough so that the forces are not transmitted to its edge (35) where the incipient fractures could appear.
  • the packaging a sheet coated on one face (36) Fig. 8, at least in the areas (37) for fixing the folds (38), of a sticky or thermo product. -solderable, and by folding the edge (39) of the folds (38) on itself so that the sticky or heat-weldable material is inside; the folds (38) are glued on themselves and a lock is obtained at the fold (40); when the packaging is in an involute of a cone Fig. 3 this operation results in a deformation of the folded upside down zone (39) Fig. 8 whose folds, if they were converging as indicated in (15) Fig. 3, become divergent, and, if on the contrary they were divergent as indicated in (16), they become convergent.
  • FIG. 19 this can be done directly or after having folded the edges (56) to make a hem or to replace or add to all the forms of fasteners described, in particular by thermal welding.
  • the fastening strip extends beyond the outer side (57) as shown in Fig. 7 as well as the inner side as shown in Fig. 10 or Fig. 12, and the inner side is turned over. (58) outwards, so as to obtain two protruding bands which after assembly it is possible to push back to fill the zones (32) and (33).
  • the fixing of a strip (46) Fig.12 is combined with the reversal of the end (47) of the folds; the purpose of this solution is on the one hand to avoid having a raw cutting packaging edge which can be sharp, and to arrange to close the areas of type (32) and (33) Fig. 1 of a strip (46) Fig.12 having the advantage of limiting the accumulation of paper there as it can be the case when using the excess width (43) Fig.11 of the folds themselves to fill this function.
