Luxembourg on behalf of: DANIEL AGUILO PANISELLO, S.A. (DAPSA) AMPOSTA (Tarragona) (Spain) for: "New folding system for cardboard boxes that can be erected and stacked." *

New folding system for cardboard boxes that can be erected and stacked.

In order to improve the mechanical characteristics of the cardboard boxes intended to contain perishable food products and also in order to increase their profitability, a new folding system has been developed which, not only increases the resistance to deformation following the crushing of the hollow corner post, but which also considerably simplifies the method of dressing the cardboard box 10, thus greatly contributing to reducing the cost thereof.

Different systems have been used in order to form corner posts allowing the cardboard box to support the weight of the other 15 boxes which are successively placed above with their contents, while keeping them centered and without this box below is overwritten.

In this regard, using corrugated cardboard as the raw material, it has been common practice to form extremely robust balusters by folding overlapping and as appropriate a succession of planes extending from the sides of the cardboard box , thus forming several thicknesses of cardboard in the baluster, this successive folding of planes in a circular direction in the same direction of 2 * * rotation.

The object of the present invention is a new version of the Spanish utility models no. 266.431 and 272.042, as well as of the Spanish utility model no. 292.019, all in the name of the Applicant, the latter utility model comprising certain improvements bringing an effective change in the way of carrying out the overlapping folding of the succession of planes i 10 extending from one of the sides of the cardboard box I, so that the two end planes fold back on themselves outward in a circular direction but in the opposite direction to that usually adopted in the aforementioned utility models, the tab on the adjacent side. remaining inserted and mechanically fixed between the two folded end planes, which combine to form the hypotenuse of a hollow prismatic triangular baluster made up of three thick-20 sors of material to support the weight of the stacked boxes, baluster whose upper end protruding spring to form the front part which will support the hollow corner post by means of a conventional socket.

This system makes it possible to form a support rib which will give the new folding system greater resistance and rigidity than those of the conventional folding systems of the prior art insofar as the end planes on one side overlap. fix them in the same way as a clamp, the tab on the adjacent side remaining firmly assembled by forming a firm support when a plastic sleeve is placed on each of the four protruding posts 35 constituting the four corners of the box cardboard-based.

: .3; The new folding system for boxes! in cardboard that can be erected and stacked brings; significant improvements with respect to conventional systems of the prior art than; 5 we apply to cardboard boxes that can be! erect and stacked and, thanks to its new con-! ception, to its performance characteristics; and shaping, as well as through speed | to which it can be trained and solidified, a new auxiliary object of great utility can be obtained, not to mention that the construction thereof is in no way complicated, thus perfectly playing the role for which it was specifically designed for, with maximum security, reliability and efficiency.

t; In order to better understand the subject of the invention, but only for information, reference is made to the accompanying drawings in which:; Figure 1 is a plan view of one of the four corners involved in the formation of the carton; FIG. 2 is a perspective view of the corner concerned in FIG. 1 during the folding process, this view showing the end planes of one of the sides closing on the judiciously folded tab on the adjacent side to form a mechanical link; FIG. 3 is a plan view of the corner concerned in FIG. 2 at the end of the folding process, this corner being thus ready to receive the sleeve whose inner walls will fix the links preventing the cardboard boxes from disassembling, this figure giving an example of a practical embodiment of the folding process; i "i. 4 Figure 4 is a perspective view of one of the four corners of the cardboard box, the sleeve being in place by covering and supporting the hollow corner post.

; 5 In Figure 1, · we can see one of the four corners involved in the formation of the corrugated box comprising the two adjacent sides (1) and (2), the latter extending through three planes (3), ( 4) and (5) joined laterally. 10 groaning to each other by internal fold lines I (6) and (7), with the exception of the plane (5), which occupies the extreme position whose fold line (8) is located outward, so much so that when the sides (1) and. 15 (2) are folded over 90 ° relative to the bottom (20)! of the cardboard box, the first plane (3), which is narrower than the other two planes (4) and (5), (folding at 90 °) will form, in section, one side, (15) of a right triangle, while the two other extreme planes · (4) and (5), which are wider, will form the hypotenuse as soon as the plane (5) falls back on the plane (4) along the line of folding (8), outwards, as shown in Figure 2.

: 25 The other side (1) of the cardboard box has a step (9) which, together with the other step (10) on the adjacent side (2) and the upper part of the three folded planes (3), (4) and (5), will form the front part: laterally and inward of the step (9) on the side (1), a tab (11) is formed which, when it is folded over 45 ° as appropriate towards the interior of the box, will be housed between the extreme planes (4) and (5) during the process of dressing the cardboard box, thus forming 'i *. 5 a support rib (12) which, thanks to the new folding system specified here, will constitute the! i \ (13) hollow prismatic triangular corner post. This new folding system gives the baluster (13) a resistance to crushing which is far superior to that of the balusters of cardboard boxes obtained by successive folding, insofar as this system confers , at the hypotenuse (14), a thickness of triple material, 10 besides incorporating the tab (11) on the side (1) which, in order to support the sleeve (16), will also increase the quantity of material up to a triple thickness, all these characteristics giving the hollow corner post 15 (13) a rigidity previously unknown.

In order to prevent accidental disassembly of the cardboard box, a hollow plastic bushing (16) will be put in place to support the baluster (13) by the front part; the triangular prismatic bush (16) has internal walls provided with separate teeth accentuating the penetration, but preventing an accidental fall when these teeth are fitted in the separate cuts (17) made at an angle in the sides of the front part.

On its flat part, the sleeve (16) comprises a nipple (18) in the form of a truncated cone projecting from the geometric center of this sleeve (16) and which, in the stacking position, penetrates into the blocking hole ( 19) made diagonally in the bottom (20) of the box, cooperating with the base of the hollow corner post (13), thereby enabling it to center the cardboard box immediately coming to the bottom. 6 1 while preventing slipping.

- We can vary the dimensions; the configurations and the materials mentioned> particularly for each of the elements of which '5 is made up of the assembly and it is also possible to make variants in all the characteristics which do not in any way modify the essential character ί of the object stipulated in the Specification above, which should be considered in its broadest sense and not as a limitation of the possibilities of realization.

Claims (4)

1. New folding system for cardboard boxes which can be erected and stacked, this system being of the type comprising, in each corner, a robust baluster formed by folding overlapping three planes extending from the side of the cardboard box , the lower end of these posts being supported on the bottom of the cardboard box at the edge of the blocking hole 10 while, together with a projection and the tab on the adjacent side, the upper end is inserted into a hollow socket in plastic material of which the lower base is open, which has a prismatic triangular shape 15 and from the upper base from which emerges a nipple on which the cardboard box immediately above is centered during stacking, characterized in that the three planes which extend from the side of the cardboard box are separated from each other by fold lines inwards, with the exception of the last extreme plane whose line of pl iage will be directed outwards, so much so that the foreground, which is narrower, defined, in section, the side of a right triangle, while the two other extreme planes wider and which are folded back 'one on the other towards the outside, form a hypotenuse jointly with a leg which will come to lodge between them and which, after having been folded 30 by 45 ° in order to better locate it between the extreme planes, will emerge on the complementary side of the box, thus forming, on the whole and together with the step emerging from the other side, the new folding system while then supporting the hollow triangular prisma- angle column. 8 '>' * * tick whose cross section will have respectively, like the sides of the right triangle, simple thicknesses of material, thus considerably strengthening the hypotenuse by a thickness 5 triple of material, thus again forming a more robust support . 2. New folding system for erectable and stackable cardboard boxes according to claim 1, characterized in that, when the prismatic triangular hollow corner post is thus formed, it will be immobilized by the addition of a socket hollow prismatic triangular whose interior walls will surround and support the hollow corner post, 15 thus preventing accidental disassembly of the cardboard box, the interior walls of this socket having separate fixing teeth which, during assembly, improve their penetration until they are accommodated in the cutouts made at a certain angle in the sides of the anterior part, thus helping to hold the socket and prevent it from accidentally falling, this socket descending until 'at the moment when its hollow bottom reaches the level of the anterior part. 3. New folding system for cardboard boxes which can be erected and stacked according to the preceding claims, characterized in that the flat portion of the socket comprises a nipple 30 in the form of a truncated cone protruding from the geometric center of the socket and which, in the stacking position, enters the blocking hole made diagonally in the bottom of the cardboard box by cooperating with the base of the colon-35 net hollow angle, thus allowing to center <. 9 the cardboard box located immediately above, preventing it from slipping. 4. New folding system for upright and stackable cardboard boxes, substantially as described in the above specification and illustrated in the accompanying drawings.
