Description

BOX THAT CHANGES THE CONFIGURATION OF ITS CLOSURE AFTER OPEN FOR THE FIRST TIME AND PROCESS FOR ITS MANUFACTURE FIELD OF THE INVENTION The present invention is related to the packaging manufacturing industry, more specifically to the breakfast cereal box manufacturing industry and even more specifically to the breakfast cereal box manufacturing industry which allows the changing of the packaging system. close after the box was opened the first time.

BACKGROUND OF THE INVENTION The packages of the state of the art consist of traditional rectangular boxes that allow to handle and contain the bags of cereal, which have a seal that is feasible to take off to allow the output of the product. The boxes in which the bag is contained have a simple closing system by means of a tab that is inserted in a slot.

Additionally, there are simple bags that contain cereal and that are distributed and sold in that way. These bags have different characteristics in terms of rigidity, thickness of the sheet with which they are manufactured, densities, etc.

In the case of the bags there is a lack of protection to the integrity of the product, and a difficulty in the handling of the product during its distribution and placement on the shelf.

In the case of traditional cereal boxes, the disadvantages are the way to close the box, since the clamping tab can easily be broken, not allowing the subsequent closing.

On the other hand is known the density of this type of product called breakfast cereals, where the density is very low, occupies a large volume for low quantities, occupying too much space that occupies the cupboards. This is mainly because the packaging is carried out with a large air space in between the product and the bag that contains it and between the bag and the box. This causes that the box occupies a relatively vo-luminous space in the cupboard.

It is clear that the use of the box under current conditions is very advantageous for handling packaging and distribution, however it is not for the storage of the packing in the cupboard.

Also taking into account that the inner bag must be sealed so that the humidity does not modify the organoleptic characteristics of the product. This seal is normally carried out by winding the free end of the bag on itself. This form of seal is not suitable since the bag tends to unwind allowing air to enter. Another solution is the use of a clamp or any other device that holds the different sides of the bag together.

A box design that allows normal handling in the packaging, storage, shipping, transport and distribution and allowing a closure that provides more resistance and occupies less space in the cupboard of houses, and also allows a closure with a certain seal The air, more or less permanent, of the internal bag would be an important advance in the state of the art.

OBJECTIVES OF THE INVENTION One of the objectives of the present invention is to make possible a closure system that allows the consumer easier to handle and protect the product.

Another objective of the present invention is to give the package characteristics that allow a better use of space in the cupboards of the houses, after having opened the package for the first time.

Still another object of the present invention is to achieve the above advantages without affecting the excellent stowage, distribution and shelf-placement qualities.

Other objects and advantages of the present invention may be apparent from the study of the following description and the accompanying drawings for illustrative purposes only and not limitation.

BRIEF DESCRIPTION OF THE INVENTION In short, the present invention is reflected in a box of breakfast cereals. Said box comprises inside the bag containing the product. Said box comprises a front face, a rear face, two side faces, an upper face and a lower face, the front face and the front face or the face face having a larger surface.

The characteristic of this box is to understand on the lateral sides, at its upper end, marked lines forming an isosceles triangle with the vertex upwards, reaching the end and having the base and sides of the triangle in curved shape, with the convex base down and the concave sides facing outwards.

In addition to the opening that has one of the flaps forming the upper face of the boxes of the state of the art, the box comprising the teachings of the present invention comprise an opening in the face opposite to that which has the flange which normally, in the boxes of the state of the art is inserted in the opposite flap.

This arrangement of the isosceles triangle lines described above allows joining the upper ends of the front and rear faces of the box, folding on the lines the side faces at their corresponding ends with these lines and folding the flap of the upper face comprising the flange, hugs the ends and said flange is inserted in the opening to lock the flange-opening closure.

Prior to this operation, the upper end of the inner bag is kept closed by means of the flap of the upper face of the box that folds down and inwards. The ends of the bag and the flap of the upper face are held in place by the approaching of the upper ends of the front and rear faces and the locking of the flange and the aforementioned opening.

The folding operations of the lateral faces in their upper ends allow, also evacuate the air that could have been trapped in the bag, and preventing the entry of air from the environment, thus prolonging the shelf life of the product contained in said bag.

In another of the aspects of the present invention is the manufacturing process of the box, this consists of the preparation of a template where the different faces of the already formed packaging will be marked by means of plie-gue lines, as well as the flaps that will form the upper and lower faces. The crease lines of the isosceles triangle and the opening of the padlock on the face opposite the face attached to the flap of the top face comprising the pad forming tab will also be reflected.

In order to better understand the characteristics of the invention, the present description, as an integral part thereof, is accompanied by the drawings, which are illustrative but not limiting, which are described below.

BRIEF DESCRIPTION OF THE DRAWINGS Figure 1 shows the template from which the box containing the teachings of the present invention will be obtained by means of its assembly.

Figure 2 shows the box before its opening, in a conventional perspective.

Figure 3 shows the open box with the flaps forming the upper face.

Figure 5 shows the box with the upper flap opposite the flap comprising the tab of the padlock, keeping the upper ends of the inner bag.

Figure 6 illustrates a conventional perspective view of the box with the shape it acquires with the closed after having opened the box for the first time, after packing.

For a better understanding of the invention, a detailed description will be made of some of the modalities thereof, shown in the drawings that are attached to the present description for non-limiting illustrative purposes.

DETAILED DESCRIPTION OF THE INVENTION The characteristic details of this novel package for breakfast cereals will be shown with the detailed description of the modality illustrated in the attached drawings, indicating the same parts with the same reference signs.

Figure 1 shows the template from which the box containing the teachings of the present invention will be obtained by means of its assembly. The main sections that will form the body of the box are the one corresponding to one of the lateral faces 1, it will become either the front or rear face 2, the lateral face opposite to the face 1, that is to say the face 3, the face that will become, when the box is armed the back or front face 4 and finally the eyebrow 5, which may be attached to the back or front face 4 or to the side face 1.

On the side faces 1 and 5 there are folding lines 6 in the form of an isosceles triangle with the base and curved sides, the base being convex with downwards and the sides with concavity facing outwards. This triangle meets the upper vertex very close to the upper end of the lateral face. This triangle is on both side faces.

Corresponding to each of the faces already mentioned, have at their upper ends separate skirts 7, 8, 9 and 10 to fold and adhere to form the upper face of the box. These skirts have certain elements that allow them to carry out a function in the closing procedure of the lock of the opening of the box, when the box has been opened for the first time.

The skirt 8 has a folding line 11 surrounding the padlock closure flange 12. This folding line 11 allows a certain deformation of the skirt area where the flange is located so that it can be maneuvered to enter the slot that consists of the other element of the padlock.

In the skirt 10, which is the one corresponding to the face opposite the corresponding face of the skirt with the flange, a truncated triangle shape 13 is received very close to the base.

The corresponding face with this skirt containing the suction, also has a suture of the same configuration and dimension. The position of this suture on the face is located centered longitudinally and very close to the upper end of said face.

The skirts that are going to form the lower face, that is to say the skirts 14, 15, 16 and 17 have no characteristics that should be noticed, unless the service 18 corresponds to the dimensions and configuration of, but complementary to, the flange 12. This maybe in order to make the most of the sheet material from which the template is cut.

Figure 2 shows the box before its opening, in a conventional perspective. In this case, the female element 14 of the locking lock of the closure can be seen on the rear face 4. You can also see some of the elements already described in the detailed description of Figure 1.

Figure 3 shows the open box with the flaps forming the upper face. The flap 8 comprising the flange 12, the rear face 4 comprising the female element 14 of the padlock and the side face 1 comprising the fold line 6 and some more elements already described and which would not provide any advantage in the description to repeat them.

Figure 4 shows the open box to which the side flaps have been detached. The flap 8 comprising the flange 12, the rear face 4 comprising the female element 14 of the can-die and the side face 1 comprising the fold line 6 and some more elements already described and which would not provide any advantage in the description repeat them As can be seen from a comparison of this figure with respect to figure 3, the elements 7 and 9 consisting of the upper flaps of the lateral faces are missing.

Figure 5 shows the box with the upper flap 10 opposite the flap comprising the flange 12 of the padlock, keeping the upper ends of the inner bag 19. The additional element that appears in the present figure in relation to the others already described is the bag containing the cereal inside, whose upper part is seen and is indicated by the numeral symbol 19, part of which is locked by the flap 10.

Figure 6 illustrates a conventional perspective view of the box with the shape it acquires with the closed after having opened the box for the first time, after packing. As can be perceived, the upper ends of the faces 2 and 4 were joined through the folding of the fold line 6 decreasing the space occupied by the package. For this, the flap 8 wraps the upper ends of the front and rear faces of the package and the corresponding flange 12 is inserted in the slot 14 to lock the lock of the closure. The folding of the upper part of the side faces also makes it possible to keep the flap 13 locking the upper part of the inner bag containing the product. With this, as already mentioned, space is gained in the place where the package is stored and also allows to expel the air contained in the internal bag and prevents the entry of air inside it, increasing the shelf life of the product.

The invention has been described sufficiently so that a person with average skill in the art can reproduce and obtain the results mentioned in the present invention. However, any person skilled in the art who is competent in the present invention may be able to make modifications not described in the present application, however, if for the application of these modifications in a certain structure or in the manufacturing process thereof, the subject matter claimed in the following claims is required, said structures should be understood within the scope of the invention.
