i

  CARDBOARD PACKAGING FOR FRAGILE OBJECTS

AND USE OF SUCH A PACKAGING

  The present invention relates to a corrugated cardboard packaging for fragile objects and the use of such packaging. It is known to pack heavy objects which

  must be protected against impact during transit

  wearing by means of foam blocks placed in a cardboard box or using PVC blocks or using beads

of polystyrene.

  The first packaging in foam blocks or PVC blocks has the disadvantage of using a lot of space for storage and of being not very compliant with environmental protection standards In addition, the use of such blocks increases the cost of packaging

  in significant proportions.

  Packages using beads or bottles

  cons of foam are certainly less bulky but this type of packaging also has the drawback of being not very compatible with environmental protection standards and of causing pollution to the user by

  the scattered beads. A first object of the invention is therefore to propose

  be a packaging that is less expensive to produce while offering effective protection that is not harmful to the environment and whose storage takes up less space. This object is achieved by the fact that the packaging in

  corrugated cardboard for fragile objects requiring

  tection against shocks during transport and comprises a corrugated cardboard box of determined thickness in which is disposed a pair of shock absorbing bellows each consisting of a sheet of corrugated cardboard of determined thickness comprising a cut-out allowing the object to be nested to be protected in an opening formed by the lateral bands of the cutout which

  hold the object laterally, this cut allows

  both the creation of depreciation means in the neighboring

  swims from the bottom of the box, said packaging also comprises an upper padding allowing the upper part of the object to be pressed to be pressed in determined locations. According to another particularity, the thickness of the cardboard must be between 5 and 7 mm for a weight

  of packed object between 6 and 7 kilos.

  According to another particular feature, the damping bellows consist of a diagonal cutout connected on the one hand to the side strip and on the other hand to the bottom of the cutout, said bottom forming a U-shaped fold oriented towards the sides of the cardboard box, said fold

  extending by a U-shaped interlocking direction

  opposite and having a side adjacent to the fold for envelope

  lopper the end of the object and cutouts forming

  shims to keep the faces of the socket at a distance

  sides of the cardboard box.

  According to another particularity, U-shaped shims are arranged at the four corners to reinforce the angles of the cardboard and press by their central part on the

sides of the object to be packed.

  According to another particular feature, the upper padding consists of two cylinders with a square section connected by a central part. Another object of the invention is to propose a

use of packaging.

  This goal is achieved by the fact that the packaging

  is used to pack printers and the padding

  rage presses on the printer cover.

  According to another particularity, each shock-absorbing bellows is extended upwards by a portion folded in a square and oriented so that one of the branches is parallel to the sides of the box, the other branch is both parallel to the branches of the nesting in

  U shape and perpendicular to the sides of the box.

  According to another particularity, the angle of the square comprises over a portion of its length a

  cantilever in the form of a bend at right angles to the direc-

  tion opposite the angle of the square.

  According to another particularity, the cantilever-

  allow the sheet guide to be maintained

  printer and user manual.

  According to another particularity, the cylinders of the upper padding comprise, on a portion of their edge situated opposite, a bending at right angles towards the interior of the cylinder to constitute an overhang.

  support of a respective shoulder of the printer cover.

  In another feature, the upper padding presses on the shoulder of the printer cover

  and, by means of protection, on the flanks of the

  tection of the leaf pulling mechanism.

  According to another particularity, one of the protection means is wedged on the side of the drive gear between the gear of the tractor and the gear of the plate and the other means of protection

  is fixed by an opening to the release lever.

  According to another particularity, lateral wedges

  between the printer chassis and

the roller.

  Other features and advantages of the pre-

  sente invention will appear more clearly on reading

  of the description below made with reference to the drawings

  annexed in which: FIG. 1 represents a perspective view

  exploded view of the packaging and its use for packaging

  lers printers; FIG. 2 represents a top view of a damping bellows arranged on one of the sides of the printer; FIG. 3 represents a top view of the upper padding element; FIG. 4 represents a side view of this same padding element after shaping; Figure 5 shows a perspective view

  of the printer, protective cover removed.

  The packaging, as shown in FIG. 1, consists of a corrugated cardboard box comprising, as usual, flaps forming the upper cover and cutouts on the lateral sides forming grip handles This box receives a first bellows shock absorber (2) and a second shock absorber bellows (4) in which U-shaped sockets (29, 49) are formed to receive the sides (56, 58) of a printer

  (5) Above the sockets, the bellows extend

  gent by angled parts, one side (275) of which faces the lateral side of the package and the other side (267) of which is parallel to the lateral side of

  packaging A padding (3) consists of a

  central tie (30) provided at its ends with two cylinders (31, 32) of square section to press on the shoulders (510, 511) of the cover (51) of the printer (5) The damping bellows (2 , 4) have, at the upper part in the U-shaped socket, a cutout allowing reverse folding to form a shoulder (270, 470) on which is placed the sheet guide (8) and the user manual (7 ) This

  sheet guide (8) and manual (7) are arranged transversely

  versally with respect to the axis of symmetry of the printer roller The damping bellows (2) forms with the interlocking a U-shaped part, the central part of which consists of a tongue (212) connected to a base (200) forming one of the legs of the U, the other leg being constituted by one of the legs of the U-shaped socket which is oriented in an opposite direction This U-shaped bellows is oriented towards the empty space of the packaging,

  so that the two sockets (29, 49) are found

  wind with their openings facing each other Above each socket is a third square-shaped portion, one side of which faces in the direction

  opposite to the U of the socket towards the lateral sides

  corrals of the corrugated box (1) Bellows

  shock absorbers (2, 4) are formed in a square sheet

  wavy tone, as shown in Figure 2 This sheet has a groove (20) formed on the face opposite the face visible in the figure and a groove (21) also formed on the same face at a distance allowing to achieve between the two grooved the tongue (212) of the bellows Two points of the grooved (21) leave two oblique cutouts (211, 210) constituting a bevel which is connected to lateral bands (22, 23) obtained in

  the sheet of corrugated cardboard by the cutouts (220, 230).

  These cutouts (220, 230) are arranged between fold lines (24, 26) The fold lines (21, 26) form the ends of the legs (214, 256) of the U of the U-shaped socket when the sheet is arranged around the object to be wrapped Two grooves (24,) constitute the joints between the central part

  (245) of the U and the legs of the U All the grooves mentioned above

  above or thereafter are made on the face opposite to that visible in FIG. 2, some grooves are

  provided during manufacture of a counterform allows

  both the folds according to the configuration shown

  figure 1 Cut-outs (250, 251, 253, 252), respectively

  vement (240, 241, 242, 243) form tongues which, when folding the U-shaped socket, extend the lateral legs (256, 214 respectively) in the direction opposite to the opening of the U so that these tongues constitute support wedges on the lateral faces of the box (1) The upper part of the cardboard sheet (2) is extended upwards by a portion folded at right angles and oriented so that one of the branches ( 267) is parallel to the sides of the box and the other branch (275) is both parallel to the branches (256, 214) of the socket and perpendicular5 to the sides of the box The branch (267) is delimited by a side by the groove (26) and on the other side by a groove (27) which, in the central part, is interrupted by two perpendicular cuts (273, 271) This groove (27) is made on the face opposite to the front face of the figure The ends of the cutouts (273, 271) are delimited by s grooves (272, 274) formed on the rear face of the cardboard, these grooves are reinforced by dotted cutouts and, in the central part, a groove (270) is formed in the extension of the groove (27) but disposed on the opposite side, on the visible side of FIG. 2 The lateral bands (22, 23) participating in the nesting of the sides of the printer (5) to be packaged have two grooves (231, 234), respectively (221, 224), arranged on the face opposite to that shown in FIG. 2, and two other grooves (232, 233) respectively arranged on the opposite face The grooves (232, 222) are in the extension of the groove (25) while the grooves (233 , 223) are arranged in the extension of the groove (24) The grooves (231, 221) are arranged in the extension of the groove (26) and the grooves

  (234, 224) in the extension of the groove (21).

  FIG. 3 represents the upper padding element which makes it possible to press the upper part of the object to be packaged, in this case the cover (51) of the printer (5), on the shoulders (510, 511) by the

  sockets (34, 33) shown in Figure 4 The rem-

  stuffing (3) consists of a central part (30)

  which is extended on both sides by two dry cylinders-

  square tion (31, 32) in which sockets (33,

  34) are practiced over part of the width of the

  stuffing These sockets (33, 34) being intended to press on the shoulders (510, 511) of the printer cover The sheet of corrugated cardboard constituting the padding has a central part at the end of which two grooves are formed ( 320, 310) and, at a certain distance from these two grooves, two other grooves (321, 311), at a certain distance from the grooves (321, 311), a third groove (313, 323), these three grooves being practiced on the face opposite to that shown in FIG. 3 and finally, at a certain distance from the third groove (313, 323), a fourth groove (312, 322) is made on the face visible in FIG. 3 The third groove (313 , 323) is interrupted by transverse cuts, respectively (332, 334; 342,

  344) performed at a certain distance from each other.

  These cutouts are delimited at their ends by grooves (341, 340), respectively (331, 330), formed on the face opposite to that shown in FIG. 3 and finally a central groove (343, 333) is located in the extension grooves (323, 313) and formed on the face opposite to the face of the groove (323, 313) This makes it possible to constitute the sockets (33, 34), as shown in

Figure 4.

  The printer is held in place by the two damping bellows (2, 4) which rub against the walls of the box (1) The printer rests on the side (214) respectively (414) of the bellows (214, 200, 212) and respectively (414, 412, 400), the sides of the printer (56, 58) being nested respectively in the sockets (245), respectively (445) The sides (214, 414) of the bellows are not not horizontal but

  slightly tilted towards the top of the box.

  In addition, before mounting the printer in the bellows, the tractor carriage is raised to allow a first damping strip (81 figure 5) to be slid between the roller drive gear (53) and the gear (52) carriage drive

  tractor On the opposite side, the tractor cart

  carries a release lever (54) on which a

  second damping strip (80), made of material

  riau of the type commerialized under the brand "EPERAN", is mounted on the lever (54) thanks to a non-visible slot made on this strip (80) Then the strips are wound on the respective flanks (501, 502) of the element tractor, so that the two strips (80, 81) are disposed between the sides (501, 502) of the tractor element and the bosses of the printer cover constituting the shoulders (510, 511) Before putting into operation place the printer cover (51), we also slide, between the printer chassis and its roller,

  shims made of rigid material which allow trans-

  printer roller side These shims rectan-

  gulars consist of a square portion (700, 710)

  adopting a rectangular tongue (701), respectively

  tively (711), the tongue (701, 711) being placed between the frame and the roller The material of the shims may be of the type sold under the brand

  "Akylux" by the company Kaysersberg.

  In this way the roller is immobilized trans-

  versally and the tilting movements, which can cause the pulling carriage to pivot, are prevented by the wedging of the bands (80, 81) and the padding (3) which presses on the shoulders

(510, 511).

  The shock absorbing bellows play a role

  printer weaving in the event of a fall and the tabs (212) and (412 not shown) lastly describe the total weight of the printer Finally, U-shaped shims (6 figure 1) are arranged at the four corners of the packaging and press on the sides (57, 59) to keep the printer in the packaging and thus relieve the side bands (22, 23; 42, 43) These wedges (6) in the shape of a U reinforce the cardboard box and prevent crushing of

corners of the box.

  The thickness of double-corrugated cardboard

  will be chosen to satisfy, for the front setting

  tal and back constituted by the bellows (2, 4), the following references marketed by Kaysesberg: Bico 240 corresponding for the upper sheet to a grammage of 240 gr / m 2-P 112 corresponding to a groove in recycled paper of grammage 12- P 150 corresponding to a recycled paper forming the intermediate sheet between the grooves having a grammage of 150-P 112 corresponding to a groove made of recycled paper of grammage 12-Bico 240 or Kraft 200 corresponding for the sheet less than a grammage of 240 gr / m 2 RC flute; for wedging

  upper consisting of the padding (3), the references

  following references: Bico 240-P 112-Bico 240 or Kraft 200

  groove C; for the cardboard holds (6), the references

  following references: Bico 240-P 112-P 150-P 112-Bico 240 or

  Kraft 200 flute BC; and for the box (1) the references

  following frequencies: Bico 200-MM 112-Gray 150 MM 112-Bico flute BC This corresponds to cardboard thicknesses of 5 to 7 mm which are suitable for effective shock absorption in the event of a falling object to be packed

weighing approximately 6.4 pounds.

  Other modifications within the reach of the skilled person are also part of the spirit of the invention.
