Figure 17 is a perspective view of the closure shown in figures 14 to 16, with the elements disassembled and partially in section.

Figures 18 and 19 are respective views that show two palletized boxes according to the present invention in the stacked position.

As shown in the figures, the box Palletizing of the present invention consists substantially of a lower platform or base part 1, an upper cover 2 and a foldable laminar part or cardboard box whose position, when it is assembled, shown in figures 18 and 19 illustrating two boxes stacked designated by reference numerals 4 and 5 and that it has the base or platform 4 'and the cover 4' 'as well as the part 4' '' intermediate laminar and, with respect to box 5, the base 5 'with its 5 '' lid and 5 '' 'side laminar part, respectively.

The constitution of the palletized box that forms The object of the present invention is suitable for production of platform 1 and cover 2 by injection molding of thermoplastic material, since existing sections and reinforcements Several areas that will be evaluated later are designed to give great rigidity and mechanical resistance to the parts that They constitute the box, as well as a light weight to it.

On its upper face, the lid 2 of the box palletized (Figure 2) includes cavities 6, 7, 8 and 9 in the that the seats of the connection closures of the laminar element, as will be described in detail below. Similarly, on said upper face, the cover comprises three rows of adjacent location lugs to the large sides of the lid and which are indicated by numerals 10, 10 ', 10' 'and 11, 11', 11 '' of reference, respectively, which take the form substantially of a truncated pyramid with rounded edges and comprising a third central row of location lugs that are indicated by reference numbers 12, 13 and 14 of the two lugs of the extremes, in other words, those indicated by the numerals 12 and 14 reference which are substantially cone-shaped truncated whose base is a circle segment, as shown in the Figure 5, while the means 13 for location of the central part It takes the form of a circular truncated cone. These means of location match in size and position with those of platform 1 shown in figures 7 and 9 illustrating the seats of the shape of coupling of rows 15, 15 'and 15' 'of one of the sides and 16, 16 'and 16' 'on the other side, the corresponding ones being indicated  central seats by reference numbers 17 and 18 of the seats of the ends and 19 of the central seat. This allows the fast centering and retention of the box and lid for stacking the same.

To allow the coupling and retention of themselves in the folded position, as shown in figure 2, said platform and cover have hookable structures in the folds thereof, and the lid 2 also has a plurality of peripheral tabs that project through its lower face, as shown in the figures illustrating two of them in each one of the large sides, those on the corresponding side shown in figure 4 which are indicated by numerals 20 and 21 reference. Identical eyelashes are arranged in a identical arrangement on the opposite side, as shown in the Figure 6, which also shows one of the tabs 22 on the side opposite. These tabs are in the form of retention means antiseparation or hook at its ends, shown in figure 6 with reference numerals 23 and 24, so that, after its introduction into the corresponding openings of the platform, shown in figures 7 and 9 with numerals 25 and 25 'of reference on one of the large sides and 26 and 26 'on the side opposite, the lid is retained on the platform, adopting a compact and rigid structure as shown in figure 2 in the that the palletized box is fully folded adopting dimensions very compact that facilitate the storage and transport of the same.

Another feature of the palletized box that form the object of the present invention refers to the production of removable slide assemblies, which are illustrated in the Figures 11 to 13, each set of three elements being made corresponding to the sides and center of the box, respectively and which are designated in said figures by numerals 27, 28 and 29 reference. These slides are elongated parts with a flat bottom face, as shown in figure 11, to allow the easy movement of them on roller tracks or other surfaces and comprising, on the opposite side, said of another way, on the top side, location media groups that they are similar in shape to the box and lid that have been described previously herein, which have been indicated by their form of truncated pyramid and designated by numerals 30, 30 and 30 '' of reference on slide 27 and 31, 31 'and 31' 'on slide 29. Sliding element 28 has means 32 and 32 'of location truncated cone-shaped terminals with the base in the form of circular segment and a projection or protuberance 32 '' central in Circular truncated cone shape. These slides are complemented by other groups of bumps, sometimes of the type male and female arranged in pairs adjacent to each of the location means mentioned above, showing, for example, the pair of respective means 33 and 33 'of male and female location that they correspond to protuberance 30 and are combined with seats of coupling form with the lower protuberances of the platform, in a concordant number, those corresponding to a row of one of the major sides that are designated by the reference numerals 34, 35 and 36 in figures 8 and 10 and by 37 and  38 that complement the row on the smaller side shown by the reference numerals 36 to match the corresponding big side row. Thanks to this means provision of male and female location and projections of the slides and of the protuberances of the platform, it is possible to attach each of the slides 27, 28 and 29 in the corresponding row of platform bumps simply and rigidly, as You can see especially in figures 1, 2, 18 and 19.

The lid and the palletized box platform they have means for joining two elements together by cinching them which, as indicated, is especially appropriate when the platform and box cover are used to contain other boxes less than, once assembled, constitute a form parallelepipedic similar to that shown in figures 18 and 19 that correspond to the use of a laminar element of lateral closure or box of cardboard.

To facilitate the aforementioned cinching, suitable openings are arranged on the sides of the box 2, indicated in figure 1 by reference numerals 39 and 40 that are correspond to openings arranged analogously on the platform to facilitate cinching.

As mentioned, when the palletized box use the laminar element for the side closure of the box cardboard, locking elements will be arranged on the lid and the platform to retain said laminar element. Such closures they comprise transversely movable tabs that are inserted in openings of said laminar element or cardboard box. The Precise constitution is shown in Figures 14-17. figures show one of the closures formed of an upper part 41 and another lower part in the form of a coupling 42 that receives the part 41 superior in its central hollow 43 and a guide 44 in which find the side flanges 45 of the bottom 42. The two parts 41 and 42 are arranged on the respective part upper and lower of one of the multiple seats 46 arranged at the bottom of the corresponding cavities of the platform and lid, as shown with numerals 6 to 9 of reference in figure 2. The seat 46 has a shape that it looks like a figure eight in a plan view (figure 17), so the projecting part in the form of cone 47 truncated polished from the bottom part 42 can slide through the inside of said seat that has retention positions on the end parts relatively enlarged seat 46 in which the entrance of the protrusion 47 after passing through intermediate zone 48 narrower will present a clear sense of retention and indicate acoustically to the user that the bra has been shifted to one or another side, in other words, which is in the closed position or is open

The formation by injection molding of the lid and box platform that forms the object of the The present invention allows the production of reinforcement zones of complex shapes on both the lid and the platform, showing Figure 5, for example, multiple ribs 49 and 50 on the cover 2, which are substantially arranged in a mutually disposable arrangement perpendicular parallel to the large sides of the lid, showing the Figure 9 platform 1 equipped with multiple flutes such like 50 and 51 that are mutually perpendicular and parallel to the platform sides complemented in certain areas, so modular, by other diagonally arranged ribs, said of another way, obliquely to the grooves 50 and 51 and with points of intersection both in the center of each of the zones and in the vertices of them.

As an example, two of said nerves of reinforcement have been designated by numerals 52 and 53 of reference. However, it can be seen that the provision modular sets of mutually perpendicular nerves that are they cross with other diagonally arranged nerves, it extends over most of the internal face of the platform, as shown in figure 9, without covering only flat areas such as indicated by reference numerals 54, 55 and 56 in which the means of location of the stack are arranged.

Another feature of the palletized box, which forms the object of the present invention, resides in the arrangement special for stacking in which, after partial hitching of the stacked parts, free zones are established with supports free for manual clamping.
