Description

Sept g 6 PACKING CASE ESPECIALLY FOR TRANSPORTING HEAVY GOODS Filed May 18, 1964 R m w W United States Patent 8 Claims. (:1. 229-23 The present invention relates to a composable packing box or case suitable to be piled with many other similar boxes, especially for the transportation of heavy goods.

An object of the invention is to solve in an economical way the problem of packing products and in particular heavy products, which at present have to be packed into cases made of Wood or of some other expensive material,

by primarily using paper or cardboard material or some other cheap laminated material which is going to be suitably reinforced.

Another main object of the invention consists in that the packing boxes of the invention may be easily assembled into their final form, while for the transportation of the empty boxes, these may be transformed into a sheet and superposed to each other.

Another object of the invention consists in that the boxes or cases may be easily assembled just before their utilization, said assembling operation being very simple and rapid and not requiring any trained person, as it will be explained hereinafter.

These and other objects will be attained by the cases according to the present invention which substantially consists in that it comprises at least one sheet of foldable material which is suitably sheared and provided with bending lines to be assembled into a parallelepiped box, said sheet including a central rectangular bottom surface with a hole at each corner, first appendant portions extending from each side of said bottom surface and adapted to be bent at right angle thereto, second appendant portions extending from said first appendant portions having a hole at each of their corners, and being adapted to be bent parallelly to the bottom surface inwardly With respect to the box and at right angle to the first appendant portions, four angle rods with a blind hole axially extending from each of their base, and four connecting members, said angle rods being intended to be placed with their axis perpendicular to the central bottom surface and, with their lower blind holes in register with the holes thereof and, upon binding of said first and said second appendant portions, with part of their side walls in contact with said appendant portions, whereby the upper blind holes of each angle rod and the holes of the second appendant portions, which are bent to cover the upper surface of said angle rods, are brought in reciprocal register relation to be in a position to receive said four connecting members which penetrate therein for holding together the different components of the box, each of said connecting members comprising a pin, a flange like spacer body and a tapered extension projecting from said spacer body in a direction opposite to the one of the pin, the holes of the bottom surface and the lower blind holes of the relative angle rods located thereupon being adapted to be engaged by the tapered extensions of the connecting members belonging to the box situated below in the pile of boxes.

Although the angle rods are connected with the cardboard box only through said second appendant portions at the boxs side opposite to the bottom surface, said boxes are additionally stabilized during the piling by having the lower holes at each corner of the bottom surface engaged by the extensions of the connecting members of the box below which also enter into the lower blind holes provided in the angle rods of the superposed box, thereby making the piles of boxes very stable.

3,270,943 Patented Sept. 6, 1966 It results that the packing boxes of the invention are very Well suited to be piled upon each other and to be transported with large transport means since the larger is the number of piled boxes the stronger becomes the structure of each single box.

In virtue of the fact that the angle rods are made of rigid material and have a considerable resistance to compressive stress, the boxes of the invention are capable of sustaining much higher loads than the conventional boxes.

The invention will be described hereinafter by referring to an embodiment which has been illustrated by way of example only in the accompanying drawing, in which:

FIG. 1 is a perspective view of a packing box of the invention;

FIG. 2 is a vertical section along the line 2-2 through an angle rod assembled in a box identical to the one shown in FIG. 1, said box being placed on an identical box;

FIG. 3 is a view in a reduced scale of the surface development of the laminated cardboard to be formed into the packing box of the invention;

FIG. 4 is a perspective view of a box corner with the angle rod mounted and the connecting member ready for entering the angle rod hole;

FIGS. 5 and 6 show in a perspective view the lower part of the box;

FIG. 7 represents a different way of forming the box by means of two rectangular sheets crossing each other. This form has the advantage of giving a double bottom and avoiding swarfs of material of the concave corners.

With reference to the accompanying drawing, the laminated sheet A e.g. of cardboard material is shown in combination with the rigid angle rods B and with the connecting members C.

The sheet A, as shown in FIG. 3, is sheared hard paper or cardboard surface provided with bending lines and capable of assuming upon bending of its sides, the shape of a parallelepiped box. In particular, said sheet consists of a central bottom surface 1 and of two pairs of first appendant portions 22 and 3-3 forming the lateral walls of the box which are respectively connected to the central bottom surface 1 by means of the bending lines 2a and 311. Second appendant portions 2' and 3' extend from said first appendant portions 2 and 3 and serve to secure the angle rods B to the box (as shown in FIG. 1) and contemporaneously as ribs for the crosswise stiffening of the box walls.

A cover portion of the box could be formed by having at least one of the second appendant portions 2 and 3' extend for a larger amount than the other ones forming a lid 3" to cover the upper box opening.

The angle rods B (FIG. 4) are right prisms with triangular base preferably made of wood. They may be made of other material as well as long as it is rigid and resistant to compressive stresses.

Said angle rods may have a quadrilateral base or a circular one, in any case they have two blind holes 4-4 axially projecting from their lower and upper base surface.

The sheet A is provided with holes 5, one at each corner of the bottom surface 1, With holes 6, one at each lateral end of the second appendant portions 2, and with holes 7 one at each side corner of the second appendant portions 3.

Each connecting member C comprises a pin 8 which may be of a cylindrical form or any other suitable shape -at head 9 and a tapered extension 8' which, in assembled 3 in one corner of the central bottom surface 1 with its longitudinal axis perpendicular thereto and with its lower blind hole 4 in register with the hole of the bottom surface, then the first appendant portions 2 and 3 are bent along the bending lines 2a and 3:: at right angle to said central bottom surface, whereafter the second appendant portions 2' and 3' are bent inwardly with respect to the box and at right angle to said first appendant portions 2 and 3. The corner portions of said second appendant portions 3' and 2' are superposed two by two and cover the upper surface of the angle rod B (FIG. 4) so that their holes 6 and 6 are brought in register with the upper hole 4 of the angle rod B. Thereafter the pin 8 of the connecting member C is pressed into said holes, this operation having to be carried out at all four corners.

In the piling phase, the head portion 8' of the connecting member projecting upwards from the flange-like spacer body 9, penetrates into the hole 5 of the central bottom surface 1 of the box placed immediately above and then in the corresponding holes 4' the lower base of the angle rod B, thereby securing the lower bottom surface 1 of sheet A to the angle rod B.

As it clearly results from the foregoing, the piling of a large number of boxes improves the connection properties of the pile of boxes which is the more stable the larger is the weight upon each box.

This is a very desirable feature since it is just in their piled-up state that the boxes, being subjected to the largest loads and especially to the largest perpendicular stresses, must be very firmly connected to each other.

While in FIG. 3 there is shown a unique sheared sheet used to form the box according to the invention, said box may be also made up of two cross-wise superposed sheets with holes 5 in register with each other. The resulting box having a double bottom surface is stronger and more resistant than the boxes made of only one sheet. In the case of boxes made of two superposed sheets there would be no discarded material at the four corner sections. If corrugated cardboard is used, the direction of corrugations in the two superposed sheets are preferably at right angle to each other to attain a further reinforcing effect. When two superposed sheets are used one of said sheets may have openings cut therein with the same section as the angle rods, said opening being adapted to receive the base portion of said angle rods to stabilize same during the assembling operation and piling.

The extensions pins 8 of the connection members are preferably of tapered conical shape and extend for a short amount. They merely serve as centering means for the piled up boxes. In the embodiment of FIG. 3 it Will not be necessary to completely out out the disc corresponding to the hole 5, but it will sufiice to cut it partially and push it into the hole 4' of the angle rod B to consent the engagement of the extension 8 of the lower box with the hole 4' of the angle rod B relative to the box immediately above, whereby the bottom surface of the box above is secured to its respective angle rod B.

What is claimed is:

1. Composable packing box suitable to be stacked with many other similar boxes in particular for the transportation of heavy goods comprising at least one blank of foldable material which is suitably sheared and provided with bending lines to be formed into a parallelepiped box, said blank including a central rectangular bottom surface with a hole at each corner, first appendant portions extending from each side of said rectangular bottom surface and adapted to be bent at right angle thereto, second appendant portions with a hole at each corner of their lateral ends, said second appendant portions extending from said first appendant portions and being adapted to be bent parallelly to the bottom surface inwardly with respect to the box and at right angle to said first appendant portions, further four angle rods with a blind hole axially extending from each of their base, and four connecting members, said angle rods being placed on the central bottom surface with their axis perpendicular thereto, with their lower blind holes in register with the holes thereof and, upon bending of said first and second appendant portions, with part of their surface in contact with said appendant portions, whereby the upper blind holes of each angle rod and the holes of the second appendant portions, which are bent to cover the upper surface of said angle rods, are brought in reciprocal register relation to be in a position to receive said four connecting members penetrating therein for holding together the different components of the box, each of said connecting members comprising a pin, a flange-like spacer body and a tapered extension projecting from said spacer body in a direction opposite to the one of the pin, the holes of the bottom surface and the lower blind holes of the relative angle rods resting thereupon being adapted to be engaged by the tapered extensions of the connecting members of an adjacent box positioned below.
