Description

Palletized box

The present invention relates to a box palletized that provides sensitive characteristics of novelty and inventive activity with respect to what is currently known.

The palletized box object of this invention is intended to contain miscellaneous items with a base platform and a top closure cover preferably related to an intermediate folding laminar element or "cardboard" constituting what is commonly known as "box", widely used for transport of all kinds of parts and articles in various industries, for example, the car industry and others.

The palletized box object of this invention is specially designed for manufacturing by injection in regards to the platform and the lid and for be able to adopt a very compact folded structure in which the platform receives the laminar element or intermediate "cardboard" from folded form and the lid that is retained with with respect to the platform by means of tabs with a profile of anti-recoil retention that are inserted into platform openings integrating the very compact set and Stable for storage and transport.

In addition, the palletized box object of the present invention presents means to allow its displacement over roller paths, which take the form of removable skates coupled to the protrusions protruding from the bottom of the platform, so that the palletized box can take shape suitable for transfer on roller paths, presenting the detachable skates that have been indicated. Alternatively, the box can be arranged for stacking on other platforms when detachable skates have separated from the platform. Also, the palletized box object of the present invention features devices for locking the sheet folding or "cardboard" that have a greater ease of use and prevent the loss of the component elements of the elements that integrate the closures.

At the same time, the palletized box object of the The present invention presents conveniently arranged openings, both on the platform and on the lid, to allow the union of said elements with each other by cinching, which is especially useful in the case where the palletized box is used without intermediate closing laminar element between platform and lid, for example, for the palletized transport of several boxes of smaller dimensions that, once stacked on the platform they integrate a parallelepipedic structure whose base coincides with the rectangular box and lid shape.

For your better understanding they are attached, by title explanatory example but not limiting, some drawings of a preferred embodiment of the present invention.

Figures 18 and 19 are views representative of two palletized boxes according to the present invention in stacking position.

As can be seen in the figures, the box Palletizing of the present invention consists essentially of a lower platform or base piece (1), an upper cover (2) and a folding sheet or "cardboard" (3) whose position in assembly situation can be seen in figures 18 and 19, in which can be seen two stacked boxes designated with the numerals (4) and (5) that present respectively the base or platform (4 ') and cover (4' ') as well as the intermediate sheet (4 '' ') and, with respect to the box (5), the base (5') with its lid (5 '') and the lateral laminar piece (5``).

The constitution of the palletized box object of The present invention is suitable for the manufacture of the platform (1) and cover (2) by injection of thermoplastic material, so the existing sections and reinforcements of different zones which will be appreciated below are intended to get a great rigidity and mechanical resistance in the integral parts of the box and at the same time a great lightness of them.

The lid (2) of the palletized box presents in its upper face (figure 2) recesses (6), (7), (8) and (9) in the that the housings for the union closures of the laminar element, as will be detailed later. Also in said upper face, the cover has three stop alignments of centering adjacent to the major sides of the lid and that have indicated respectively with the numerals (10), (10 '), (10' ') and (11), (11 '), (11' '), adopting substantially truncated pyramidal shape with rounded edges and arranging a third alignment center of centering stops that have been indicated with the numerals (12), (13) and (14), being both of the extremes, that is, the indicated with numerals (12) and (14) substantially conical trunk whose base is a circle segment as you can observe in figure 5, while the centering (13) of the part Central adopts circular conical shape. These centers coincide in position and dimensions with those of the platform (1), Figures 7 and 9, in which the housings are observed conjugate of the lateral alignments (15), (15 ') and (15' ') for one side, as well as (16), (16 ') and (16' ') for the other, being the corresponding central housings indicated with the numerals (17) and (18) for the ends and (19) for the central. From this way, fast centering and cash retention is possible and lid for stacking.

To allow coupling and retention in folding position, as shown in figure 2, presenting said platform and cover nestable structures for its folded and in addition, the cover (2) has several peripheral tabs protruding from its lower face, as seen in the figures in which they have been represented in number of two for each one of the major sides, having been indicated with the numerals (20) and (21) those of the corresponding side represented in Figure 4. In on the opposite side, the same tabs are arranged with the same arrangement, as it is possible to appreciate in figure 6, in which it is observed also one of the tabs (22) on the opposite side. These tabs they have a form of anti-recoil retention or hook at its ends, such as those that have been represented with numerals (23) and (24) in figure 6, so that after its introduction into the corresponding openings in the platform, visible in figures (7) and (9) with numerals (25) and (25 ') for one of the major sides and (26) and (26 ') for the opposite side, produces the retention of the cover on the platform adopting a compact and firm structure as shown in figure 2 in which the palletized box is completely folded adopting very compact measures that allow easy storage and transport.

Another feature of the object palletized box of the present invention is based on the realization of assemblies of removable skates shown in Figures 11 to 13, each set being integrated by three elements respectively corresponding to the sides and center of the box, having shown in said figures, with numerals (27), (28) and (29). These skates are elongated pieces with flat bottom face such as it is possible to appreciate in figure 11 to allow its easy displacement on roller paths or other surfaces and presenting on the opposite face, that is, on the upper face, center groups analogously to those presenting the box and lid and which have been described above, having been indicated by its truncated pyramid shape and with the numerals (30), (30 ') and (30' ') for the skate (27) and (31), (31 ') and (31' ') for the skate (29). As soon as to the skate element (28), it has extreme centers (32) and (32 ') with a truncated conical shape with the base in the form of a segment of circle and a protrusion or central protuberance (32 '') in shape circular conical trunk. These skates complement each other groups of bumps, in some cases of male and female type in arrangement of pairs adjacent to each of the centers mentioned, observing, for example, the pair of centers (33) and (33 '), respectively male and female, corresponding to the protuberance (30) and that are combined with shape housings conjugate of the lower bumps presented by the platform, in corresponding number, having been represented in Figures 8 and 10 with the numerals (34), (35) and (36) the corresponding to an alignment of one of the major sides and with the numerals (36), to coincide with the corresponding alignment of the major side and (37) and (38) that complete the alignment of the side minor represented. Through this arrangement of centers and male and female protrusions of the skates and the bumps of the platform, it is possible to attach, in a simple and firm way each of the skates (27), (28), (29), in the corresponding alignment of platform bumps, as it is possible to appreciate especially in figures 1, 2, 18, and 19.

The lid and platform of the palletized box present means for connecting both elements to each other by cinching, which, as indicated, is especially appropriate in the case of using the platform and the cover of the box to contain other smaller boxes that integrate altogether a parallelepipedic form similar to that represented in Figures 18 and 19 corresponding to the use of element laminar side closure or "cardboard".

To allow the cinching mentioned, timely openings are arranged on the sides of the lid (2), indicated in figure 1 with the numerals (39) and (40) that are correspond to openings arranged analogously in the platform to allow cinching.

As indicated, in the case where the palletized box use the side closing laminar element or "cardboard", locking elements will be arranged on the lid and the platform to retain said laminar element. Such closures they have transversely movable tabs that are inserted in openings of said laminar element or "cardboard". The precise constitution is seen in figures 14 to 17. In said figures, one of the closures consisting of a upper part (41) and another lower part in the form of a latch (42) which receives the first embedded in its central hollow (43) and a guide (44) in which the side tabs (45) of the piece coincide lower (42). The two pieces (41) and (42) are arranged in the top and bottom respectively of one of the multiple accommodations (46) that are arranged at the bottom of the cavities corresponding to the platform and the lid and which have been represented with the numerals (6) to (9) in figure 2. The accommodation (46) has a plan similar to (figure 17) an eight, so that the protruding part gently conical (47) of the lower part (42) can slide inside said housing presenting retention positions in the parts relatively widened ends of the housing (46) in which the coincidence of the bump (47) after going through the narrower intermediate zone (48), will provide a clear feeling of retention and will indicate, even acoustically, to the user that the bolt has been displaced on either side, that is, it is located in the closed position or it is open.

The injected constitution of the lid and the palletized box platform object of the present invention allows the realization of reinforced areas in complex ways both on the lid as on the platform, having been represented, pro example in figure 5, in the cover (2) multiple ribs (49) and (50) noticeably arranged perpendicular to each other parallel to the major sides of the lid, having represented in figure 9 the platform (1) equipped with multiple ribs such as (50) and (51) perpendicular to each other and parallel on the sides of the platform that are complemented by zones, in shape modular, by other nerves arranged according to diagonals, that is, obliquely with respect to nerves (50) and (51) and with points of I find both in the center of each of the areas and in the vertices of them.

As an example, two of said reinforcement ribs with numerals (52) and (53). Without However, it is understood that the modular arrangement of sets of perpendicular nerves to each other conjugated with others in disposition diagonal extends to most of the inner face of the platform, as seen in figure 9, running out of Simply cover flat areas such as those indicated with numerals (54), (55) and (56) in which the stacking centers.

Another feature of the palletized box object of the present invention consists of the special provision for stacking in which after partial fitting of the stacked parts are arranged free zones with free steps that They allow manual grabbing.

Everything that does not affect, alter, change or modify The essence of the described box will be variable for the purposes of the present invention
