Description of the invention

In order to achieve the objectives and avoid the drawbacks mentioned in the previous sections, the invention proposes improvements introduced in cardboard boxes that they comprise in principle a first laminar body and a second body laminate, including both bodies respectively, a waist outer and an inner waist that make up at least the walls sides of the box generating a concentric structure, including the box plus a bottom, while the extreme sections of both waists join to form the closed contour of the double waist

The improvements of the invention are applicable both to boxes with free mouth as to boxes with mouth closed.

The improvements are characterized by the sections ends of the waist, exterior and interior, are joined together independent in a common confluence zone through a first adhesive material and a second adhesive material that are in contact with facing surface portions that are part of such waists; further characterized by that in the area of Common confluence cited, an inner portion of the waist exterior is arranged in the same coplanar plane as a portion outer of the inner waist, so that in the area of union a thickness formed by the sum of three is generated from both waistlines partial thicknesses that are part of the two laminar bodies of cardboard: a first central thickness formed by the two portions cited coplanarians, a second internal thickness that is part of the inner waist and a third outer thickness that is part of the outer waist.

The improvements are also characterized by the fact that facing free edges of the coplanar portions, exterior and inside, they are in contact with each other.

Another possibility is that the free edges facing the aforementioned coplanar portions, exterior and inside, be separated, conforming in this case a hole intermediate between such free edges facing each other.

The improvements are also characterized by the fact that in the common confluence zone where the extreme sections of both meet There is a corresponding bending line with one of the vertical corners of the box and which conforms to the confluence of the free edges facing the portions, exterior and interior, of both waists.

The laminar bodies that make up the box Cardboards comprise a multiple corrugated of up to 4.5 or more channels. It should also be noted that the structural elements are reinforced that have to endure efforts during stacking boxes. In addition, the structure presented by the box of the invention facilitates its handling during assembly improving ergonomics. Too It should be noted that the flaps are thinner (not laminated), folding more easily than for example a triple box curly.

Next to facilitate a better understanding of this descriptive report and being an integral part of the same accompany some figures in which with character illustrative and not limiting the object of the invention.

A cardboard box 3-3 ' it comprises in principle a first laminar body 1 and a second laminar body 2, including both respectively, at least one 1 'outer waist and a 2' inner waist that make up the less side walls of the box generating a structure concentric, also including the box at least one bottom 4-4 'formed by extensions that are part of al minus one of the laminar bodies mentioned 1-2.

Starting from this premise, the improvements of the invention focus on the arrangement of the extreme sections of both 1'-2 'waistlines that both join together independent and also focus on improvements in the provision of the relative position of such extreme sections of both waistlines 1'-2 '.

So, the extreme sections of the waist exterior 1 'are joined by a first adhesive material 1' 'that is in contact with two surface portions that are part of both sides of such outer waist 1 ', joining such sections ends with each other through said first adhesive material 1 '' to ensure the closed perimeter formation of the outer waist one'.

Likewise, the extreme sections of the waist 2 'inside are joined by a second 2' 'adhesive material that is in contact with other surface portions that are part of both sides of such inner waist 2 ''.

It should be noted that an inner portion 5 of the 1 'outer waist is arranged in the same coplanar plane that an outer portion 6 of the inner waist 2 ', so that in the zone of union of both waists 1'-2 'is generated a total thickness formed by the sum of three partial thicknesses that they are part of the two laminar bodies 1-2 of paperboard:

- a first central thickness that corresponds with the inner portion 5 of the outer waist 1 'and the portion outer 6 of the inner waist 2 ', both portions being 5-6 in the same plane and facing their edges free.

- a second internal thickness that corresponds with an inner portion of the inner waist 2 '.

- a third external thickness that corresponds with an outer portion of the outer waist 1 '.

According to figure 1, the fold lines 7 to form the vertical corners of the box are made in the areas where the box has double thickness, this being applicable solution in cases where two consecutive side walls they form a right angle and in cases where the angle is smaller of 90º.

Instead, when two side walls Consecutive form an angle greater than 90º, as shown in Figure 2, one of the corresponding fold lines 7 'with a from the vertical corners of the 3-3 'box, you can make such a fold line 7 'through the joining area of the two waistlines 1-2 and more specifically for the area of confluence on the free edges facing the portions, outer 6 and inner 5 of said inner 2 'and outer waists 1 ', respectively, whereby said fold line 7' affects in this case to the three partial thicknesses mentioned above.

The free edges facing the portions, exterior 6 and interior 5, in one embodiment they are in contact (Figure 2), while in the other embodiment shown in the Figure 1, such facing free edges are separated, generating in this case an intermediate gap 8 to compensate or tolerate small variations in die cutting or cutting 1-2 laminar bodies that integrate such waists, exterior 1 'and interior 2'.

In order to improve corner bends 7-7 'and therefore the assembly of the box, before performing such folds is done in correspondence with them a drawing that generates an internal depression 9 along such corner folds 7-7 '.

In summary, then, the union of the extreme sections of both waistlines 1'-2 'is performed in a characteristic common confluence zone 10 where the three partial thicknesses that are part of extreme portions of both waist 1'-2 '.
