Definitions

• the present invention relates to a new unrolled wooden packaging.
• the shapes of the trays are limited by the characteristics of the unrolled wood, presenting fibers that lead to the risk of breakage in case of folding with a small radius angle. Moreover, the dimensional variations as a function of the degree of humidity also limit the achievable forms.
• the object of the present invention is to provide a new form of container, compatible with a manufacture by folding and assembly of a wooden sheet unrolled.
• the invention relates more particularly to a tray made of unwound wood characterized in that it has an octagonal section, consisting of a bottom having the general shape of a cross, two arms are two sides of the trays , the other two arms being laterally extended by sections forming the side walls of the tray after shaping.
• said two arms constituting the sides of the trays extend in the direction of the wood fibers.
• said arms constituting the sides of the trays have at least one prerine line perpendicular to the fiber direction, to allow formatting.
• said arms constituting the sides of the trays have two pre-shaped lines perpendicular to the fiber direction, to allow shaping.
• the tray preferably has three pairs of opposite sides at least having the same dimension measured on the upper edge.
• the arms extended by the sides have on both sides two tabs separated by pre-formed lines, said tabs forming two adjacent sides after attachment to the arms forming the other two sides.
• the laterally extended arms are longer than the arms forming the sides, before drying the wood.
• the legs and arms are assembled by snapping on the sides, gluing, stapling or sewing.
• the difference in length between the two arms is between 3% and 10%.
• FIG. 1 represents an exemplary embodiment of a regular octagonal container
• FIG. 2 represents an exemplary embodiment of FIG.
• An irregular octagonal tray - Figure 3 shows a tray shaped in plan view
• Figure 4 shows a tray shaped in a bottom view.
• Figure 1 shows a first embodiment of a tray according to the invention.
• She is formed from a poplar leaf unrolled, cut with a matrix.
• the cutout has the general shape of a cross, with a bottom (1) of octagonal shape, extended by a first pair of arms (2, 3) whose central axis (10) extends parallel to the axis of wood fibers, and by a second pair of arms (4, 5) whose median axis (20) extends perpendicularly to the axis of the wood fibers.
• the first arms (2, 3) are hinged to the bottom (1) by means of two sets of half-cuts (21, 31) and (22, 32).
• the tabs (2, 3) thus have a first pair of facets (23, 33) which will form cut sides when the tray is shaped, and a second pair of facets (24, 34) forming two opposite sides of the tray .
• the bottom (1) is extended, in the direction parallel to the wood fibers, by two lugs (4, 5) which are extended on both sides by sections (41, 42, 51, 52). These sections will form four sides of the tray after shaping, two additional sides being formed by the end of the tabs (4, 5).
• Sections (51, 52) and (41, 42) are delimited on either side by cut-to-flesh cuts (45 to 48 and 55 to 58), oriented perpendicular to the wood fibers.
• the consecutive cuts (45, 47), (46, 48), (55, 57), and (56, 58) are not quite parallel, but form an angle of about 18 ° between them.
• the ends (53, 54, 43, 44) are secured to the sides (24, 34) after shaping, and held by gluing, stitching, sewing, latching or any other means.
• the sides of the bottom which are not extended by tabs (2, 3, 4, 5) have convex cuts (6 to 9) avoiding tearing of the wood during the shaping.
• the bottom has a dimension L1 measured before drying between the imaginary lines (49, 59) delimiting the lower edge of the sides (4, 5) less than L2, where L2 represents the distance between the fold lines (22, 32) delimiting the lower edge of the sides (24, 34).
• the difference in length is about 5%. This difference in length appears in the area (40, 50) extending between the pre-line (49, 59) and the bottom (1).
• the length of this zone (40, 50) is greater than the length of the homologous zone (20, 30) between the lines (22, 32) and the bottom (1).
• the sides of the tray are formed by the parts (52, 5, 51, 24, 41, 4, 42) each having a width of 60 millimeters.
• Figure 2 shows a variant of tray shaped irregular octagon.
• the tabs (4, 5) are wider than the portions (51, 52, 41, 42) constituting the complementary sides.
• Figures 3 and 4 show views of the shaped tray respectively in top view and in view from below.
• the tray is shown when the wood still has a high degree of moisture, usually just after the shaping operation.
• the shaping is carried out using a tool comprising a domed matrix, having a surface substantially corresponding to the surface of the bottom (1), and bearing elements which fold the arms (2 to 4) and the lateral extensions of these arms.
• a counter-matrix is placed inside the tray and serves as a support for receiving the arms and their extensions, until the complete assembly.
• the bottom (1) has a convex shape with two beads (70, 71) resorbing the excess length according to the direction parallel to the fibers, between the bottom (1) and the arm (4) on the one hand, and between the bottom (1) and the arm (5) on the other.
