Detailed description of the embodiments preferred

Referring to the drawings and, in particular, to figure 1, there is an example of a semi-finished 10 made from cardboard or sheet material similar folding to form a wrapping box according to the invention presenting a plurality of panels to form a beam-shaped structure 14 arranged therewith, for packing One or more items. Said semi-finished comprises a plurality of panels in series to form a box that presents a cover, a base and opposite side walls. In this way of realization the semi-finished one comprises a first wall panel of base 12, the beam-shaped structure 14, a first panel of side wall 16, a lid wall panel 18, a second panel of side wall 20 and a second base wall panel 22 attached each other in a series-articulated manner along the lines of fold 30, 32, 24, 26, 28 respectively.

The beam-shaped structure 14 extends between the first base wall panel 12 and the first panel of side wall 16, being joined in an articulated manner thereto through a couple of provisions of cartouche. In this way, the beam-shaped structure 14 can be interposed between parts of the article (s) to support it (s). Preferably the beam-shaped structure 14 is stamped at least in part on the first base panel 12 and on the first side wall panel 16, so that the parts of the panels previously mentioned that do not form the structure in the form of beam, are part of the outer walls.

In this embodiment, each provision of cartouche comprises a cartouche panel 34, 36 attached so articulated along one edge to the first base wall panel 12 along the fold line 30 and to a first panel of side wall along the fold line 32 respectively. Preferably, the panel panels 34, 36 have a shape substantially trapezoidal and fold lines are provided 30, 32 along its longer edges. Each panel of cartouche 34, 36 is articulated along each of its edges oblique sides opposite a pair of reinforcement panels 42a, 42b and 42c, 42d along the fold lines 44a, 44b, 44c, 44d respectively. Reinforcement panels 42a, 42b, 42c, 42d they have a substantially triangular shape in the form of preferred embodiment of Figure 1. Of course, the shape of the panel and / or reinforcement panels are not limited to the ways described above and are expected to used other ways to provide, for example, a beam of a substantially "V" shaped cross section inverted

The reinforcement panels 42a and 42b are joined by articulated way along a fold line 46a to the first and to the second support panel of article 38 and 40 respectively. Also, the reinforcement panels 42c and 42d are joined together articulated along the fold line 46b to the ends opposites of the first and second support panel of article 38 and 40 respectively.

In this embodiment, an intermediate panel 48 separates the support panels from article 38, 40 and is joined by articulated way to them along their side edges via the fold lines 50, 52. The intermediate panel 48 is jointed together, in the preferred embodiment, to the shortest edge of the panel panels 34 and 36 by means of the fold lines 46a and 46b.

Returning to the construction of the illustrated box in figures 2, 3 and 4, it is provided that the present box invention can be shaped by a series of operations sequential folding and, optionally, gluing that can be performed on a known continuous production machine in a manner that it is not required to turn or invert the box to finish your building. The folding procedure is not limited to that It is described below and can be modified according to particular manufacturing needs. The items are shown Invested only for the sake of clarity.

Referring first to the figure 2, the lid wall panel 18 of the box semi-finished 10 is puts in contact with the flat upper face of the items A by a relative vertical displacement between them. Returning to figure 3, the semi-finished 10 is then mounted to provide a pair of side walls arranged in opposition by folding the side wall panels 16, 20 towards inside around fold lines 24 and 26. The panels of cartouche 34, 36 fold out of alignment with the first base wall panel 12 and the first side wall panel 16, of so that the first base wall panel 12 is arranged on the basis of articles A.

At the same time, or simultaneously, it build the beam-like structure 14 by folding the first and the second support panels 38, 40 along the lines of common fold 50, 52 in an angular relationship with each other and with the intermediate panel 48 (figure 4), so that intermediate panel 48 be taller The folding of the first and the second support panel 38, 40 allows simultaneous reinforcement panels 42a, 42b and 42c, 42d fold out of alignment with the brackets 34, 36.

Advantageously, the first and second panels of support fold automatically under the introduction of the beam-shaped structure in the free space included between adjacent items A. To achieve this folding automatic, the width of the intermediate panel 48 is equal to or less than the spacing between adjacent jars but the width displayed total beam-shaped structure 14 is wider than the Jars spacing. The intrinsic resilience of the folded cardboard ensures that an adjustment is maintained without strike between the support panels 38, 40 and the articles.

Then the second base panel is folded 22 on the basis of articles A and fixed to the first panel of base wall 12 using a glue, or other suitable means known in the art, such as interlocking means mechanical, thus forming, for example, a base wall compound. The box is now fully assembled, as is shown in figures 4, 5 and 6 with a beam of a section transverse substantially in the form of an inverted "U".

The angular relationship between the Support panels 38 and 40 can be modified by moving the lines fold 44a, 44b, 44c, 44d and / or fold lines 46a, 46b according to the particular requirements of the beam-shaped structure 14. Poster panels 34, 36 are not limited to presenting a  trapezoidal shape. In other types of embodiment, it is provided that the support panels can be folded up to form an inverted structure beam. In some ways of embodiment, the second base wall panel can be extended to cover the entire base, and can possibly be foreseen with a fin to be fixed to the first side wall panel 16.

In some embodiments, the panels of Beam support can be curved, as shown in Figure 5, to fit the articles in order to improve the rigidity of box. In these embodiments the support panels They work as coupling bands. Preferably the panels 38, 40 are curved along the fold lines 44a, 50, 44d; Y 44b, 52, 44c and these fold lines can be oriented to better fit the shape of the adjacent article.

Returning to a second embodiment of the invention as illustrated in figures 7, 8 and 9, the parts equals, if possible, are represented by equal reference numbers with the addition of the prefix "1". The second embodiment is similar to the first form of realization, so that only the differences are described in more detail.

Referring in particular to semi-finished 110 as illustrated in figure 7, this form of embodiment differs from the first embodiment in that the first side wall panel has been omitted and the structure in beam form 114 is therefore linked in an articulated manner to the lid wall panel 118 along the fold line 132. Additionally, the beam-shaped structure has been extended in length to compensate for the omission of the first wall panel side.

Going back to the beam-shaped structure 114 in more detail, it can be seen that in this way of embodiment the support panels 138 and 140 are connected between yes articulated along a common crease line 143 and that, in addition, reinforcement panels have been omitted so that support panels 138 and 140 have a trapezoidal shape and are directly linked in an articulated manner to the panels of cartilla 134 and 136 along the fold lines 135, 139 and 137, 141 respectively.

Going back to building the box for form a fully assembled box as illustrated in the Figures 8 and 9, it is planned again that the box of the second embodiment can be shaped by a series of sequential folding and gluing operations that can be performed in a continuous production machine so that it is not required turn the box or invert it to finish its construction.

The folding operation is developed substantially as described in the first embodiment and results in the semi-finished that forms a tubular box surrounding articles A. Next, the first and the second panel 112 and 122 each other using a queue or other means suitable known in the art to form a base wall Composed as shown in Figure 8.

The beam-shaped structure 114 is constructed folding the first and second support panels 138 and 140 at along its common fold line 143 in an angular relationship each other so that fold line 143 is higher, in This embodiment.

Advantageously, the first and second panels of support fold automatically under the introduction of the beam-shaped structure 114 in the free space comprised between adjacent items A. To achieve this folding, the width of support panels 138, 140 when in state coplanar is wider than the space between jars Again, the intrinsic recovery capacity of cardboard folding ensures that an adjustment is maintained without strike between support panels 138, 140 and articles.

Those skilled in the art will appreciate that the combination of an enclosure arrangement with an inclined beam interposed between items substantially prevents displacement relative between items A and the box you can if not compromise the automatic handling of the boxes and the stacking of the same. In this way, the beam arrangement can be used to replace the end retention means that have been used so far to avoid relative displacement horizontal between the items and the box, but that generally requires that an additional folding stage be performed as part of the assembly procedure.

It will be recognized that as they have been used in the present report, the terms "cover", "base", "lateral", "superior" and "inferior" with respect to box panels are relative terms, and that box can redirect as necessary or desired. Any reference to articulated joints should not be construed as referring necessarily only to a single fold line; in fact it is provided that an articulated joint can be formed from a marked line, a frangible line or one, two or several lines of fold without departing from the scope of the invention.

The present invention and its embodiment preferred refer to a beam-shaped structure in a box envelope that is configured to provide resistance satisfactory to keep at least one item safely but with a degree of flexibility so that the load that is transfers to the beam-shaped structure be absorbed by the box. The semi-finished shape minimizes the amount of cardboard required. The box can be applied to an item arrangement manually or by automatic machinery.
