Description

New collapsible packaging of the crate type- pallets, including a container in the shape of a right prism with an octagonal cross-section. The present invention relates to a variant of the collapsible pallet box type, comprising a container in the shape of a right prism with an octagonal cross-section and a plane of symmetry, in accordance with the main patent. It is recalled that this pallet box comprises: - a packaging body in the shape of a right prism with an octagonal cross-section having a plane of symmetry, the edges of which are formed by fold lines and two of whose walls are parallel to this plane of symmetry; - and a base integral, on one side, with this packaging body, so as to close it at one end, and, on the other side, with a handling pallet, which may be in one piece or made up of two half-pallets arranged symmetrically with respect to the plane of symmetry. of the packaging body. According to claim 1 of the main patent, this pallet box is characterized by the fact that: - the base comprises two first flaps, each joined, on the one hand, by a fold line, to the base of two parallel walls of the packaging body arranged symmetrically with respect to the plane of symmetry, and on the other hand, by means of a triangular tab hinged by a fold line on said first flaps, to the base of the two walls adjacent to each of said parallel walls, said triangular tab being itself hinged by a fold line on said adjacent walls and being such that, in the assembled position of the packaging body, it comes to rest against the adjoining flap, perpendicular to the walls of said body, projecting outwards from it; - optionally, two second flaps are joined respectively by a fold line at the base of the two last walls of the packaging body arranged perpendicularly - aligned with the plane of symmetry, these second panels, in the assembled position, come into contact with the inner face of the first panels facing the interior of the packaging body; - the last walls perpendicular to the plane of symmetry are divided along this plane by a fold line parallel to the edges of the body and extend in the same plane along the entire length of the second panels to allow the packaging body to be folded flat, whether attached to the half-pallets or not; - each of the first panels is attached, respectively, by its outer face, to the pallet or to one of the half-pallets. The base and the packaging body may form a single unit from a single piece of cardboard or corrugated cardboard (claim 5 of the main patent) or constitute two separate parts, the base portion comprising a imitation body with very low-profile walls adjoining said flaps, which are fixed to the corresponding walls of the packaging body. (claim 6 of the main patent). This addition aims to offer a simpler and more robust variant of the pallet box according to claim I of the main patent. In this variant, the packaging body remains unchanged and the base still comprises two first flaps, each joined, on the one hand, by a fold line, to the base of two parallel walls of the packaging body arranged symmetrically with respect to the plane of symmetry, and on the other hand, by means of a triangular tab hinged by a fold line on said first flaps, to the base of the two adjacent walls of each of said parallel walls, said triangular tab being itself hinged by a fold line on said adjacent walls and being such that, in the assembled position of the packaging body, it comes to rest against the adjoining flap, perpendicular to the walls of said body, protruding outwards. of this one. According to this addition, however, the said first panels, attached to two parallel walls of the packaging body, constitute a single base element, divided in two by a fold line which, in the assembled packaging, is located in the plane of symmetry of the packaging body, and the two walls perpendicular to this plane of symmetry are attached by fold lines to said base element and are divided along the plane of symmetry by a fold line which extends that dividing the background element in two. Preferably, the base of the packaging and the body of the packaging will constitute two parts distinct, as described in the main patent. These are such forms of realization of the invention tion, wherein the base of the packaging constitutes by itself a packaging conforming to the invention with very low-profile walls, fixed to the walls of the the actual packaging body, which will be described below then in detail, by way of non-limiting example. In For this description, please refer to the attached drawings, on of which: Figure 1 is an exploded perspective view of a first embodiment of the packaging; Figure 2 is a plan view of the base; Figure 3 is an exploded perspective view illustrating a second embodiment of the packaging according to the invention; Figure 4 is a plan view of the base of this second form of realization. Figure 1 of these drawings can be compared to Figure 1 of the main patent. It shows: - a packaging body C, made of a semi-rigid material such as corrugated cardboard, in the shape of a right prism with an octagonal cross-section, open at both ends and whose edges are formed by fold lines; - a base portion F, octagonal in shape, intended to seal the body C at one of its ends. - two half-pallets P attached to the part of base and articulated together by a hinge. Body C and background F present a plane of symmetry passing through the joint plane of the half-pallets. Two opposite walls, VII and VIII respectively, of body C are perpendicular to the plane of symmetry and are divided vertically into two equal parts by folding lines arranged in this plane of symmetry. An unshown lid may cover the end upper body. According to the invention, the base comprises eight low-profile side panels, 1, 2, 3, 4, 5, 6, 7, and 8, intended to be glued to the outside of the corresponding panels, I, II, III, IV, V, VI, VII, and VIII, of the body C. The body C is formed from a single blank of corrugated cardboard of the type shown in Figure 2a of the main patent. Panels 2 and 5 are positioned respectively between panels 1 and 3, on the one hand, and panels 4 and 6, on the other, to which they are hinged by fold lines. In the assembled position of the packaging, these fold lines are substantially aligned with the corresponding lines by which the panels are hinged. between them the walls of the packaging bodies. The walls of the base section F are hinged on a single octagonal element 10, which forms the actual base of the packaging, either directly by a fold line, for walls 2 and 5, or via a triangular connecting piece, respectively 11, 13, 14, 16, 17 and 18, for the walls 1, 3, 4, 6, 7 and 8. Each triangular piece is itself- even articulated by a folding line, on the one hand, on the associated wall, on the other hand, on element 10. A folding line 20, arranged along the line of symmetry of the bottom part F and, in the assembled position of the packaging, in the plane of symmetry thereof, divides into two symmetrical parts l0a and 10b, the element 10, as well as the walls 7 and 8 and the triangular pieces adjoining 17 and 18. As described in the main patent, the packaging body can be delivered flat to users with the walls 1 to 6 of the base pre-bonded to the corresponding walls of the packaging body. In this section, the base element is folded around the fold line 10 with the two halves of parts 17 and 18 and the adjoining walls 7 and 8 applied against the two halves of element 10. To shape the packaging, the body C is first shaped. This straightens the walls of the base section attached to it and brings element 10 and the triangular pieces 17 and 18 into a horizontal position. Meanwhile, the triangular pieces are pressed against element 10, protruding outside the packaging body. In this position, the walls 17 and 18 of the base section are straightened to press them against the outer face of the walls. associated with the packaging body. All these operations can be easily implemented by the user themselves on site instructions for use of the packaging. The bottom of the packaging can be glued or stapled onto at least one of the half-pallets. Of course, we would not depart from the scope of the invention by producing packaging conforming to the invention, the base and body of which would be contiguous and made from a single blank of cardboard or corrugated cardboard suitably cut and pressed. This blank would then be of the type shown in Figure 2, but the walls 1 to 6 would then constitute the walls of the packaging itself. said and would have much greater heights. In such an embodiment, walls 7 and 8 should naturally be made integral with the adjoining walls, respectively 1, 4 and 3, 6, after installation. packaging volume. In the embodiment shown in Figures 3 and 4, we find: - a packaging body C', in the shape of a right prism - octagonal section, open at both ends, and whose edges are formed by fold lines; - a base part F', octagonal in shape, intended to close the body C' at one of its ends; two half-pallets P', attached to the base part base and articulated together by a hinge. The body C' and the bottom part F' have a plane of symmetry passing through the joint plane of the halves pallets. Two opposite walls, respectively VII' and VIII', of body C' are perpendicular to the plane of symmetry and are divided vertically into two equal parts by folding lines arranged in this plane of symmetry. The base section comprises an octagonal flat element ', constituting the base itself, and eight low side walls 1', 2', 3', 4', 5', 6', 7', 8', intended to be glued to the outside of the corresponding walls I', II', III', IV', V', VI', VII' and VIII' of the packaging body. Walls 2' and 5' are hinged to the bottom by fold lines, while walls 1' and 3', on the one hand, and 4' and 6', on the other hand, are adjoining, are articulated on the ground by the inter- diary of a triangular connecting piece, respective- 11', 13', 14', 16'. Each triangular piece is itself hinged by a fold line, on one side to the associated wall, and on the other side to the base element 10'. The walls 1', 2' and 3', on the one hand, and 4', 5' and 6', on the other, are hinged to each other by fold lines, which, in the assembled position of the packaging, are perpendicular to part 10' and coincide approximately with the corresponding lines (vertical edges) by which the walls of the body C' are articulated with each other. As in the embodiment shown in Figures 1 and 2, two other walls 7' and 8' are hinged to the flat part O10' by a fold line perpendicular to the plane of symmetry of the bottom part F' and are perpendicular to this plane of symmetry in the mounted position. A 20' fold line divides the flat 10' bottom section into two equal parts, 10'a-10'b, as well as the walls 7' and 8'. These walls 7' and 8' are internally lined by two half-walls, respectively 7'a-7'b and 8'a-8'b, joined by a fold line to walls 1', 4', 3', and 6'. Walls 7' and 8' can be externally bonded between the associated half-walls. Walls 7' and 8' can also be possibly absent, the half-walls 7'a-7'b and 8'c- 8'b are then joined together by gluing or stapling to form the walls. Heels 17', 18', 19' and 20', articulated by fold lines respectively on the half-walls 7'a, 7'b, 8'a, 8'b, are applied against the bottom part 10 against which They are glued or stapled. As in the case of Figure 2, the triangular parts 11', 13', 14', 16' protrude in position mounted outside the bottom section. In this embodiment, the packaging body can be delivered flat to users with all the walls of the base section pre-glued to the walls corresponding to the packaging body.
