Abstract

Cardboard box, presenting an octagonal outline, based on four major walls and four walls of lesser light width, and including a bottom that can be closed by flaps derived from its walls, and a top closure lid, from the open mouth itself of the box, is characterized in that two of the larger walls extend in essentially rectangular flaps but that are related to the adjacent smaller walls from triangular portions delimited by respective fold lines, said triangular portions folded external extensions that increase the support surface of the box; with the particularity that these closing flaps of the bottom have in their external free edge a notch at an angle of mutual engagement between flaps when they are folded inwards; it being further provided that alternated with said bottom closing flaps are defined two other rectangular closing flaps, affected by a groove in one case and a tongue accommodatable in the latter in the other, defining a second means of closure for the bottom of box.

Description

DESCRIPTION

Carton box.

OBJECT OF THE INVENTION 5

The present invention relates to a cardboard box, and more specifically to an octagonal base box, which has structural characteristics that offer great resistance to the box in order to contain heavy products, such as feed, granulated products, etc., where The box constitutes a container of great resistance in the storage and 10 full transport of product.

BACKGROUND OF THE INVENTION

Numerous types of cardboard boxes are known for the transport of various products, more than 15 or less heavy, but which generally suffer from a lack of resistance that results in deformations of the box and even breakage during transport and handling thereof, with the consequent spill or fall of the product.

 In the utility model 201230473 of the applicant himself, an octagonal base box 20 is described that offers a high resistance, derived as a result of the octagonal contour of the box itself, where there are four major walls and faces and four smaller ones, as chamfers and that complete the octagonal outline of the box.

 In this box, one of the edges has flaps that will form the bottom when folded, and whose flaps, in pairs, have a step that derives in a complementary fin from the other side, to crimp the flaps with each other and form the bottom, which is complemented by two other flaps derived from two other major faces to reinforce the bottom itself.

 30

However, this octagonal base case and of great strength referred to above, suffers from the disadvantage that the external reinforcing flaps that hold the closing flaps require means to keep them stable, such as gluing, staples, etc.

In addition, the box when loaded with very heavy products can carry with it a deterioration of its walls, regardless of the fact that the means of crimping the flaps that will form the bottom closure do not offer sufficient security in the crimping.

DESCRIPTION OF THE INVENTION

 40

The box that it advocates, and being of the type that has an octagonal contour, has been designed to solve the problem described above.

More specifically, the box of the invention is characterized in that two of the flaps that are going to close the bottom are derived from their corresponding sides with triangular portions with a bisector-shaped fold line, and also those two flaps that are to form The bottom closure has an angled recess so that in the closed position they engage with each other and said bottom is perfectly closed, with the particular feature that these triangular portions with the folding bisector fold outwards and extend the surface of box support, providing optimal stability to the box. fifty

On the other hand, the two flaps inserted between the aforementioned, are rectangular

and are derived from their respective sides, in order to overlap with those that form the bottom closure, and engage with each other to maintain the closure in question, so that these rectangular and interlocking flaps with each other present in one case a groove and in another one folding flap intended to engage in the groove of the other flap to keep said flaps properly stabilized, reinforcing the closure formed by the other two flaps 5 mentioned above.

The two flaps that form the initial closure of the bottom, by virtue of the triangular portions with the fold line according to one of its bisectors, determine a semi-automatic assembly of said bottom, derived precisely from the folding of said triangular portions. 10

On the other hand, it is foreseen that the box can be complemented with an internal reinforcement wall attached to that of the box itself, in order to increase its resistance and to be able to store and transport any type of bulk product, whatever its weight.

 fifteen

In addition, the box is intended for the bulk product to be housed in a bag that is disposed inside the box.

In addition, the box is assisted by an upper cover which in its central area has a climbed sector through which the mouthpiece of the bag is capable of being extracted and thus allow the extraction of the contents thereof without the need to remove or cover No bag

PREFERRED EMBODIMENT OF THE INVENTION

As can be seen in the aforementioned figures, the box of the invention is constituted from the development of a rectangular sheet, such as that of Figure 1, with transverse fold lines 50 that will form eight faces or walls, according to an outline octagonal defining four major faces (1) alternated with smaller faces (2) of slightly smaller amplitude than the

previous ones that are fixed by an extreme tab.

Well, from the development of this sheet, the novelty of the invention focuses on the fact that two of the major walls extend into rectangular flaps (3) but which are related to the adjacent minor faces from triangular portions (4 ) delimited by 5 respective fold lines, such that these triangular portions (4) in the assembly and bottom closure fold and overlap each other through the fold lines to form external lateral extensions (5) increasing thus the stability of the box in rest position, since said portions (4) when folded and projected outward increase the contour or support surface of the bottom of the box increasing its stability. 10

The flaps (3) have an angled recess (5) which, when folded thereto to form the bottom or closure thereof, engage in a complementary manner, which in combination with the folded sectors or portions (4) form a semi-automatic closure. of the commented fund. fifteen

Said bottom formed by the flaps (3) is complemented by two flaps (6), alternated with the flaps (3), said flaps (6) being affected by a window (7) in one case and a tongue (8) in the another, that when folded and superimposed on the flaps (3) they interlock with each other, specifically the tongue (8) being housed in the window (7) to keep said flaps 20 properly fixed, achieving a quick, simple and efficient closure, without the need for gluing, staples or other additional elements as conventionally required.

The box thus constituted is capable of being complemented with a sheet like that shown in Figure 2, of the same contour and which is attached to the main sheet 25 internally to form a double stiffening wall of the reinforced box.

Said sheet of Figure 2 also has four major faces (1 ’) and four minor faces (2’) analogous to the main case.

 30

Figure 3 shows the development of a lid (9), attachable on the mouth of the box, and presenting an octagonal contour with lateral wings (10), folding and fins (11), alternated with those, to form a body as an inverted bowl, adjustable to the mouth of the box, with the special feature that this lid (9) has a central and die-cut sector (12) whose breakage brings with it an opening to be able to extract through it mouth of the corresponding bag that is housed inside the box with the product contained in said bag.
