Description

"Improved corner layout for cardboard box to arm and pile up".

i

The Model ·, of utility put in relation in this memory is intended to guarantee the exploit and the exclusive property everywhere the -national territory, of an improved corner arrangement for cardboard box to arm and to pile up.

This box model is used more often every day as packaging for the transport of fruit and other perishable products because the current technique has obtained and has gradually used new designs with a significant simplification of forms and assembly. which lowers the price of the finished packaging, and that naturally have been applied in collaboration with improvements obtained in the manufacture of the first material used, ie corrugated cardboard.

It is obvious that all these improvements have been applied in the most respectful way possible on the most necessary characteristics of resistance, especially when the stacked boxes must support the weight of the upper boxes and in addition its content. For this we used on a regular basis the creation of corner pillars of high resistance on the crushing as well as having very varied solutions with lasquelles avoid that the pile can be destroyed because of a sliding caused by some upper boxes on the lower ones. In this case, the solutions given by the objects of Utility Models numbers 260.715 and '2.

♦ these solutions it was possible to obtain that the assembled box embraces in all its parts, a single thickness of material except in the corners where the pillars are constituted by a double superimposition of a succession of planes which extend the side of the box and have two or three thicknesses.

In the assembly of the box, we removed the operations of gluing on the sides and on the facade which converge at each corner, because the upper parts of the components of each pillar are assembled with precision inside a socket in plastic material in the form of a triangular base prism with a lower entry to receive the necessary parts of the pillar, the only means of mounting.

In the Model-enhanced corner layout, the same guidelines are maintained as in the Utility Models mentioned, but with some variations that provide the following advantages over everything that has been experienced and disclosed:

We add on the facades of the box, the successions of the plans which constitute the triangular corner pillars when they are folded.

All this allows us to approach the development of the box as much as possible on a rectangular figure in which, in a peripheral way, we can avoid the profusion of material that has made us so far, bid the price of the box.

The box is endowed with suitable means for ensuring the coupling in superposition and which defends accidental destruction.

3.

It confers a supplement to the mounting sockets of the corners of the box, to obtain gains in the distance of the superimposed boxes.

All this means that this distance can contain a product of greater height without being necessary to increase the dimensions of its development and with that, the heights of the sides or facades.

In each corner there is an empty triangular pillar where each rib has two thicknesses of material.

For a better understanding of the object as an example, attached a sheet of plans in which:

Figure number 1 represents a plan view of a corner of the development of the box.

Figure number 2, shows in perspective the arrangement for mounting different parts of the development of the box, which contribute to form a pillar of the corner.

• Figure number 3 represents the upper plan view of the mounting cartridge.

Figure 4 shows a section of the cartridge traced from A-A in Figure 3.

From the drawing of Figure 1, we can realize that the plan. On the side -1- has in its side a rung which goes out -2-, that among a line or mark of doubling -3- is separated from a wing -4- with the same height and which is separated from the exterior -1- by a cutting line -5-.

This side -1- is separated from the bottom plane -6- by. . ’4.

an inward doubling line -7- analogous to the line which separates the plane of the bottom -1- from the plane of the facade -8-, and is separated at the same time from the extreme of the side plane -1- by a cutting line -9- which enlarges the final with a notch or a rung -10-.

The plane of the facade -8- has a staggering in the edge which determines a projecting part -11- of a height similar to the projecting part -2- relative to the edge of the plane of the side -lr and this staging of the facade -8- is extended by three successive planes -12-13-14- which go separated between themselves and the facade by parai.leles lines of doubling inward -15-.

In each corner of the bottom plane -6- there is a diagonally grooved hole -16- which is part of the center of the stacked boxes.

In the rungs which have a protruding part -2- of the side -1- and -11- of the front -8-, there are angle cuts -17- which help to retain the mounting cartridge -18- for secure the corner. The components of the rungs are placed as shown in Figure 2; that is to say with the planes -12-13-14 folded, which will form a triangle so that the extreme plane -14- will remain attached to the inner face of the protruding part -11-, with this double thickness we can form one side of a right angle of the triangular part of the prism which constitutes the pillar of the corner, the other side of a right angle formed by the superposition of the plane -12- on the projecting part -2- on the side -1 -1, while the hypotenuse is formed by the superposition of the wing -4- on the side -1- refuted on the plane -14-.

As can be seen, this triangular corner pillar 5.

of the bottom -6-, while its superiero end is introduced in a fitted manner into the interior of the cartridge -18- shown in FIGS. 3 and 4, and which has the appropriate triangular shapes, which will penetrate up to a level -19- determined by a lower plane of supreme degree, formed by the three corner steps -18a- and by the bottoms of the three notches -20a- which were made in an upper part -20- where it is extended above the cartridge, and these notches begin around a projecting part of the upper piece -21- which occupies the geometric center of the part and are directed radially outwards and which open out in the central part from each of the three sides. The three walls of the landing-20-placed corner rungs -18- are very well reinforced by means of a pair of boxes -22-.

The mounting cartridge -18- is a molded piece of very light plastic material with thin walls. All this becomes very economical as an element which assures the mounting of a corner of the box and which adjusts on the triangular projecting part in order to be able to fold the box perfectly.

This cartridge -18- has two retaining protruding parts -23- which protrude from the walls which conform the two sides of a right angle of the room because during assembly they coincide with the angle cuts -17- which were made in the steps -2- on the side -1- and -11-of the facade -8- (see figure 2) and they will remain hooked on the horizontal paths.

If we assemble a retention cartridge (see Figure 3 and 4) on a corner of the box as we see in Figure 2, we ensure a profit with the height of the box when it is stacked 6 ..

"Because the box that we placed at the top, will be placed at the corners of her. bottom and supported on the bearings -20-of the cartridges of the lower box. With that, we ensure its correct placement and we avoid any slippage -21-. i

In this way, the separation between the boxes can be increased by the distance between the inner supreme degree plane -19- and the upper bearing plane -20-which is similar in each cartridge -18-, without having to vary the dimensions of the cardboard development to obtain more elevation of the corner pillars. This altitude is given by the cartridges.

The circumstances of measurement, form and material particularly told in each of the elements which belong to the whole are variable and one can vary everything, except the elements which can suppose an alteration of all the essential of the object exposed in this description, which should be considered amply and not as a limitation of possibilities to be realized.

Once described, the object and utility of this invention, it is declared not disclosed or practiced in Spain, and it has the following:
