PACKAGING.

Description

The subject of the present invention is a circumference of a box, in particular

foldable pallet box, its

  manufacture and crate including.

  Container-pallet type or similar packages currently on the market consist of different materials, each providing its specific properties in these composite structures.

  Thus, the armed box is usually formed of veneer or plywood panels, battens forming the side frames of the panels and reinforcing the structure, and stapled wires which maintain the structure and distribute

mechanical stresses.

  The hinged raised boxes include walls of wood or other rigid materials, assembled by metal hinges, and risers for placing the assembly on a pallet. In particular, such plywood boxes may comprise walls made up of

  plywood panels and hinge angles allow the assembly to bend.

  Foldable pallet boxes have also been proposed comprising a pallet of wood surmounted by a set of panels, especially of cardboard, folded for transport and capable of being erected for use, the structure thus formed being, where appropriate, reinforced by means of cleats (see for example requests for

  published patents FR-A-2,102,883 and 2,480,240).

  All these achievements require relatively large handling during their assembly (stapling, riveting, gluing ...) and often unnecessary consumption of materials unnecessarily weighing the product.

  A new structure has now been found for constituting crates, in particular pallet boxes, which effectively integrate all the elements used in a saving of material and weight, and by reinforcing by a choice of suitable materials the strength of the material. together, in the form

continuous web.

  The present invention therefore relates to a

  body rim, including foldable pallet box, 10 comprising a rectangular flexible ply having substantially the length corresponding to the periphery of the body, and rigid elements secured to the ply and defining rectangular frames respectively forming the lateral sides of the body.

  The flexible sheet consists of a material

  one-component or reinforced synthetic material, in particular a sheet of plastics material optionally laminated to other materials such as paper, aluminum, etc. The plastics material may be, for example, a polyolefin (polyethylene, polypropylene, their copolymers ...), a polyamide, a polyurethane or other materials, and it may be plain or in the form of fibers, woven or non-woven, depending on the resistance or impermeability desired, provided that its strength is sufficient for use.

  The rigid elements, secured to the web (by stapling, nailing, gluing, riveting, sewing or other means) delimit the lateral sides of the body and ensure its rigidity in repre 30 nant the mechanical forces that can not be by

the flexible tablecloth.

  The rigid elements include battens, sleepers, uprights or panels and are in particular wood or wood derivatives such as reconstituted wood, plywood, chipboard, fibreboard, but may be where appropriate

  of synthetic material (eg polystyrene).

  The body rim according to the invention com5 takes the number of rectangular frames corresponding to the number of lateral sides of the box, generally 4, but can comprise 3 or more sides, for

example 6 or 8.

  According to one embodiment, each rectangular frame consists of 4 battens (2 uprights

  and 2 sleepers), which can be fixed on the outside.

  or inside the flexible tablecloth). However, some rectangular frames (at most one in two) may include only two horizontal battens (tra15 verses), which allows a saving of material. According to various variants: the rectangular frames are all inside the sheet and the adjacent edge of the battens of two consecutive frames is bevelled in order to facilitate the folding of the periphery, without stretching the sheet, during assembly of the box; the rectangular frames are outside the sheet; the horizontal battens (crosspieces) are inside the web and are bevelled, while the vertical battens (uprights) are outside the web; the vertical battens (uprights) are inside the web and are bevelled, while the horizontal battens (crosspieces) are outside the web; - at least two of the frames delimited by

  the battens inside the sheet are separated from each other by

  to leave room for a candle that can be inserted when mounting the box; - at least one of these candles can be

attached to the tablecloth.

  'These candles fixed or inserted in the

  angles provide a triple function: stiffening angles, reinforcement stacking and securing vis-avis a fault positioning of the upper box.

  According to a variant, the vertical battens

  (uprights) have a length greater than the width of the web (that is to say the width of the periphery), this configuration to obtain a raised pallet.

  An important function of the flexible tablecloth

  according to the invention is the possibility of folding the perimeter structure. The size of the folded periphery may be substantially equal to the half-perimeter of the periphery or reduced to the length of the larger side.

  One of the main advantages of the invention lies in the simplicity of mass production

perimeters.

  According to a first preferred method, a flexible ply is placed on which the rigid elements are fixed before cutting the ply to the length of the periphery (or to a slightly greater length) and then, if necessary, the periphery thus obtained is closed. According to a second method, the sheet 30 is cut along a half-perimeter or a perimeter with

  possible surotes before fixing the rigid elements and possibly close the periphery (process mainly reserved for medium and small series).

  It is obviously possible to close the tablecloth first

then fix the rigid elements.

  The following description with reference to the accompanying drawings gives examples of

  the invention. In these drawings: - Figures 1 to 6 are top views of various embodiments of the body perimeter according to the invention; - Figures 1A to 3A are respectively views of the periphery of Figures 1 to 3; FIGS. 4A to 6A represent respectively the

  around 4 to 6 in the folded state.

  The body periphery shown in FIGS. 1 and 1A comprises a rectangular flexible sheet 1 (for example a sheet of plastic material) 15 and rigid elements 2, 3 made integral with the sheet (for example by stapling) and defining rectangular frames. forming respectively the lateral sides of the box. Each frame, inside the sheet, consists of four rigid elements which are horizontal battens 2 (or sleepers) and vertical battens 3 (or uprights), for example made of wood, the vertical battens 3 being bevelled so to facilitate the folding of the periphery and to make the structure more solid. The horizontal battens can be made integral with the adjacent vertical battens by

bonding or nailing.

  On the perimeter of cash represented on the

  2 and 2A, the rectangular frames are outside the flexible sheet 1 and are also composed of two horizontal battens 2 and two vertical battens 3. These vertical battens 3 have a length greater than the width of the web 1 , the excess length forming the base of a crate raises.

  The body rim shown in FIGS. 3 and 3A comprises battens on either side of the ply 1, the horizontal battens 2 (crosspieces) inside the ply 1 being sealed for the reasons indicated above. (Fig. 1), while the vertical battens 3 (uprights) are

the outside of the sheet 1.

  According to a variant of this last embodiment shown in FIG. 4, the tower frames formed by horizontal and vertical battens 2 2 are spaced two by two, so as to leave room for two movable candles 4 which are inserted during assembly of the body. Fig. 4A represents this same circumference in the folded state, the candles 4 being obviously not set. The perimeter of the folded perimeter

  is about the same as mounted.

  The periphery shown in FIGS. 5 and A comprises, in addition to the horizontal and vertical battens 2 and 3 on either side of the web 1, two movable chanels 4 and two candles 5 attached to the

  web, for example in the same way as the battens 2, 3 (stapling, nailing, gluing, etc.). As before, the movable candles 4 are not used when folding the periphery (FIG 5A).

  The periphery shown in FIGS. 6 and 6A comprises horizontal battens 2a and 2b inside the web 1 and vertical battens 3 outside the web 1, the relative position of two adjacent horizontal battens 2a and 2b. being end 30 against face and the battens 2b being fixed to the web only about half of their length. This arrangement allows the folding of the periphery with a smaller footprint.

  It is obvious that other variants of this type are possible, in combination with the embodiments described above and given by way of examples, without departing from the scope of the invention.
