The height of the two opposed lateral faces (2 and 6) is greater than the height of the other two lateral faces (4 and 8). On the bottom side (26), each angle face includes a slot (27) having a shape corresponding to its opposite end (28) connecting the free edges of the adjacent lateral faces.

Description

The invention relates to the field of packaging of articles, namely folding containers, and includes containers made of sheet material such as cardboard or corrugated cardboard in the form of an open box.

Known folding box described in German patent no. No. 3,150,677 for storing and transporting articles is made of sheet material having fold lines parallel to its sides for forming the bottom of the box, a hinged lid, two side walls and two end walls joined by interconnecting members having diagonal bend lines, which, when forming the box, form folds within it, having tongues inserted into the recesses 1 in the rear walls, thereby securing the resulting box.

Also known as foldable article packing boxes are described in the English patent no. 2,110,184, manufactured from a sheet material cutter having parallel bending lines which divide the cut into a base, side walls and cover, in addition to the base and lid bending lines, mutually parallel bending lines serve to form end walls with sliding lugs which secures the vessel by folding it.

Foldable vessels may be formed by folding through said bending lines and joining the wall sequences of the wall and then folding and joining the foldable edges in various known ways, but the closest of these to the present invention is described in French patent no. A 2,665,137 in the description.

The drawbacks of the known sheet-type cut-off trays are that the lids used to secure them do not allow them to be stacked. y. for open-type vessels, the projections and furrows provided for staging shall be provided therein so that the projections of the lower base vessel reach the furrows of the upper container. However, in order to connect the said protrusions and rows, which are intended to ensure the stalling and good stability of this stacked headquarters, it is necessary that the side walls of these vessels are twice the thickness of the sheet material. This greatly increases the cost of sheet material.

The object of the present invention is to eliminate the aforesaid disadvantages and to produce stacking vessels of ordinary thickness, thereby reducing the cost of sheet material.

To this end, a palletized container made of a sheet material such as cardboard or corrugated cardboard according to the invention is an open parallelepipedal box according to the overall exterior view.

The said container shall consist of:

- four side walls, square or rectangular, arranged in pairs opposite and parallel and connected by primary folding lines which are parallel to each other;

and

- a bottom on the opposite side of the aperture having four foldable edges connected respectively to said side walls by secondary lines, mutually parallel pores and all perpendicular to the primary folding lines;

By the way

- said parallelepiped open box having cut corners and two oblique corner walls, each inserted between two adjacent side walls and connected to each of said side walls by one of said primary folding lines;

- said two opposite side walls parallel to said primary folding lines have a height greater than the other two respective side walls, such that at said opening side the two adjacent side walls have free edges at two different levels and said corner wall located between said adjacent side walls of walls, protrusion connected;

and

- on each side of said bottom, each corner wall has a notch corresponding to a projection on the opposite side joining the free edges of said adjacent side walls when said notch is open on the said side so that when two such identical vessels are placed on top of each other:

- the highest portions of the two side walls adjacent to the respective secondary folding lines and belonging to the upper vessel are located in an opening of the adjacent vessel spaced transversely to the highest side walls of said lower vessel;

- the secondary fold lines of the two smallest side walls of said upper vessel rest on the free edges of the lower side walls of said lower vessel;

and

- the projections of the corner walls adjacent to the aperture of the lower leaf enter into said upper vessel furrows.

Thus, according to the invention, the headquarters is robust and the limited possibility of transverse opening of these vessels is exploited. Indeed, it is noticeable that such an expansion occurs when the contents of these vessels press against the inner walls of these side surfaces, especially when packaged articles are stacked or tiled.

The present invention encompasses stackable vessels made of sheet corrugated or plain cardboard, with an exact parallelepiped shape with cut corners, no lid, four main walls and a bottom, characterized in that:

- the height of the two side-walls is greater than the height of the other two side-walls, respectively, so that the free edges of the two adjacent side-walls are at different levels,

- each cut corner on the bottom has a notch corresponding to the opposite protrusion and

- the side walls and the cut corners are arranged so as to allow the upper edges of the two said counter walls to be recoil from one another under the pressure of the contents of the container, said contents consisting of tiles and articles facing each other which depress said side walls and cut corners.

Incision angles of planes and sidewalls usefully formed to ensure good loading of articles and best fit between corresponding walls, for example, at corners or at many angles formed by the sidewalls of said articles.

Finally, in order to increase the expansion potential contemplated by the present invention, it would be desirable for the aforementioned side walls, in parallel with the respective secondary fold lines, to be longer than said lower side walls.

Useful if the length of the lower side walls is between one third and two thirds of the length of the higher side walls.

In one embodiment of the present invention, the projection of each corner wall adjacent said opening is limited by the first edge extending the free edge of the adjacent side wall of the superior wall and the secondary edge at least approximately parallel to said primary folding lines and connecting said primary edge to the free at the edge of the lowest sidewall such that said furrows are rectangular.

According to an embodiment of the invention, the projection of each corner wall adjacent to said opening is limited by an oblique edge, joining the free edges of said adjacent side walls so that said ridges are triangular. In this way, it is possible to lay layers of free edges of the walls of said wart for the manufacture of such a dish into the folds of an identical wart for the manufacture of an identical dish, as described below. This results in extra sheets being saved.

Whatever the embodiment, it is useful to have a notch on each corner wall extending beyond at least one primary folding line and connecting said corner wall to adjacent side walls. Mostly said furrow extends beyond said primary folding line and connects said corner wall to an adjacent high side wall.

This makes it easy to insert the corner protrusions of the lower vessel into the grooves of the upper vessel.

In addition, the present invention relates to a sheet material such as cardboard or corrugated cardboard for the production of a paperboard for the above described container.

For this purpose, in another aspect of the present invention, such a wart includes:

- a sequence of four main rectangular or square walls joined by parallel primary bending lines;

and

- four hinged edges joined, respectively, to the side walls by secondary fold lines perpendicular to said primary fold lines and aligned with each other;

and besides,

- said wall sequence includes narrow auxiliary walls sandwiched between said main walls;

- the height of the two adjacent adjacent main walls parallel to the primary folding lines is greater than the respective two other main panels so that the free edges of the two adjacent main walls are at different levels and the projection of said narrow auxiliary wall inserted between the main walls;

i have

- on the side of said fold edges, the free edges of said narrow auxiliary walls are spaced relative to the secondary folding lines so that said narrow walls may, on the basis of the arrangement of said secondary folding lines, form furrows having the shape of said auxiliary narrow walls inserted between adjacent main walls. .

Thus, according to the invention, the vessel may be formed by folding through said primary folding lines, said main and auxiliary walls, and joining the outer walls of the wall sequence, and then folding and joining said folding edges. Such formation may be accomplished by any known means, but it is recommended that the technology described in French patent A 2 665 137 be used.

From the foregoing, it appears that it is desirable that the upper said main walls be parallel to the respective secondary folding lines longer than said main lower walls.

Further, the projection of each auxiliary narrow wall opposite to the bottom may be limited by the leading edge extending the free edge of the adjacent top main panel and the secondary edge approximately parallel to the primary folding lines and joining said first edge to the free edge of the smallest adjacent main wall. said auxiliary narrow walls would be rectangular.

However, it is preferable for the projection of the narrow auxiliary wall on the opposite side of the folded edges to be limited by a diagonal edge joining the free edges of the adjacent main panels so that said narrow auxiliary walls have a parallelogram shape. It is possible to stack or combine, as will be shown later, successive cuts of two identical vessels to form additional sheet material furrows.

Further, in order to facilitate insertion of the lower vessel corner wall projections into the upper vessel furrows, it is contemplated that an additional narrow wall furrow extends beyond at least one of said primary folding line by connecting said auxiliary narrow wall to adjacent said main walls. Preferably said furrow extends beyond said primary folding line by joining said auxiliary narrow wall to an adjacent main upper wall.

In the latter case, where said narrow walls are parallelepiped, the folded edges joined to the highest main walls have an expanding shape away from said secondary linked fold line and the free edge of said folded edges is at least partially contoured by a contour. the upper edges of the main wall and the diagonal edges of the two auxiliary narrow walls adjacent to said edges. In this way, it is possible to prepare two consecutive identical cuts in parallel and save additional sheet material.

The accompanying drawings show how the invention is realized. In these drawings, identical elements are designated identically. In particular, the same markings shall be used to designate the relevant elements of the cuts and dishes.

FIG. 21 and FIG. Fig. 22 is a side and longitudinal view of Figs. 13 and FIG. 17 images of visible stapled vessels.

The sheet material cut Fl, such as cardboard or corrugated cardboard, is shown in FIG. 1, comprises a sequence of eight rectangular or square walls 1 through 8 interconnected by parallel fold lines 9 through 15. Behind the free edge of wall 8 of said wall sequence is a strip 16 connected to boundary wall 8 by a fold line 17 which is parallel to bend lines 9 through 15.

In addition, folded edges 18.2, 18.4 are provided on one side of walls 2, 4, 6 and 8, respectively,

18.6 and 18.8. Each side has a curved edge

18.2, 18.4, 18.6 and 18.8 are connected to, respectively

2, 4, 6 and 8 forming a fold line

20.2, 20.4, 20.6 and 20.8. These folding lines 20.2,

20.4, 20.6 and 20.8 are at least approximately matched (except for sheet material thickness to accommodate fold edges 18.4 and 18.8 on fold edges 18.2 and 18.6 as illustrated below) and perpendicular to fold lines 9 to 15 and 17. Walls 1, 3 , 5 and 7 have no lateral fold edges.

The mutually identical walls 2 and 6 are parallel to the folding lines 9 to 17, the same height H1 and the same width L1 (parallel to the folding lines 20.2 to 20.8). Further, the two walls 4 and 8 are i

are identical with each other and have a height of H2 and a length L2 and less than H1 and L1 respectively.

In addition, walls 1, 3, 5, and 7 have lengths _1, for folding lines from 20.2 to 20.8 compared to L1 and L2.

parallel is small,

Walls 2, 4, 6, and 8 are main walls, and walls 1, 3, 5, and 7 are narrow auxiliary walls sandwiched between said main walls.

Opposite folded edges 18.2, 18.4, 18.6 and

In side 18.8, walls 1 through 8 and strip 16 are respectively bounded by free edges 19.1 through 19.6. The free edges of the walls 1, 2, 3, 5, 6, 7 and the strip 16 are aligned with each other. In addition, the free edges 19.4 and 19.8 of the walls 4 and 8 are also aligned with each other. In fact, the height H2 is less than the high H1 and consequently the free edges 19.3 and 19.5 of the walls 3 and 5 are joined by the free edge 4 of the wall 19.4 by the edges 21.3 and 21.5 which almost coincide with the fold lines 11 and 12 respectively. The edge 7 of 19.7 and the free edge 19.16 of the strip 16 are joined to the free edge of the wall 8

19.8 with edges 21.7 and 21.16 nearly coinciding with the folding lines 15 and 17. On the opposite side of the folded edges 18.2 to 18.8, the projections 3, 5 and 7 of the auxiliary narrow panels form a step 28.

On the side of the folded edges 18.2 to 18.8, the walls 1, 3, 5 and 7 and the strip 16 are bounded by the free edges 22.1, 22.3, 22.5, 22.7 and 22.16 respectively. These latter free edges are aligned with each other and form a shortening of height d (for example equal to 5 to 10 mm) relative to the folding lines 20.2, 20.4, 20.6 and 20.8. Each truncation 29 creates the shape of a step 28 that needs to be maintained. Each step passes behind the fold line 9, 10, 13 or 14, respectively, penetrating 1 adjacent main wall 2 or 6.

The fold edges 18.4 and 18.8 may be rectangular and have the same length L2 as the walls 4 and 8 to which they are attached. Their height is H3.

The folded edges 18.2 and 18.6 may extend 1 outside through the fold lines 20.2 and 20.6 with the diagonal edges 23.2,

Thanks to 24.2, 23.6 and 24.6. Their height is H4.

Useful when H1 + H3 = H2 + H4, which allows insertion of the projections of parts 18.4 and 18.8 into recesses mutually limited by the respective lines 21.3, 19.4 and 21.5 on one side and 21.7, 21.6 on the other, which belong to the adjacent truncation.

In order to form an open container according to the invention based on the cutter F1 (see Figures 2 to 6), it is sufficient to fold said cutter through the fold lines 9 to 17 and connect the strip 16 to the wall 1 so that its outer edge 25 coincides with a folding line 17, and then secured, for example, by gluing or fastening in this position said strip 16 and said wall 1. Thereby a side bar is formed. The folding edges 18.4 and 18.8 are then folded through the folding lines 20.4 and 20.8 in the middle of the side bar, and later also inside the side bar, through the folding lines 20.2 and

20.6 foldable fold edges 18.2 and 18.6 followed by said fold edges 18.2, 18.4, 18.6 and 18.8, glued or stapled together.

The diagonal edges 23.2, 24.2, 23.6 and 24.6 form an angle of 45 ° with respect to the folding lines 20.2 and 20.6 outwards, relative to the folded edge to which they belong. They end with vertical lines 23.2 ', 24.2', 23.6 'and 24.6'. which are located inside the container with respect to the folding lines 20.4 and 20.8 of the walls 4 and 8 as shown in the drawing in FIG. 6th

This arrangement helps to lift vertical loads on top of each other.

In this way, an open vessel Rl, shown in the drawings from FIG. 2 to FIG. 6, which has the general shape of an almost parallelepipedal box and an octagonal section.

The vessel Rl has four side walls, square or rectangular, in pairs opposite and parallel, and these side walls are formed by main panels 2 and 6, respectively, by main panels 4 and 8. On the opposite side of the opening, the vessel Rl is closed by a bottom 26 consisting of four foldable edges 18.2. , 18.4,

18.6 and 18.8.

The additional narrow walls 1, 3, 5 and 7 form the corner walls by cutting the corners of the vessel R1 and each being connected to said side walls 2, 4, 6, 8 by two fold lines 9 through 17.

In connection with the reduction of the lengths 29 on the free edges 22.1, 22.3, 22.5 and 22.7 of the walls 1, 3, 5 and 7, each corner wall, on the side 26 of the bottom 26, has a rectangular notch 27 open to said bottom 26. 7, FIG. 8 and FIG. 9th

If two identical vessels R1 are superimposed so that the walls 1 to 8 of the upper vessel R1 are vertically aligned with the walls 1 to 8 of the lower vessel R1 (see Fig. 2), the two vessels R1 can be joined by grooves such that ( see Figure 10 and Figure 11 solid line):

- the folding lines 20.2 and 20.6 of the two side walls 2 and 6 of the upper vessel Rl enter the opening 25 of the lower vessel Rl beyond its free edges 19.2 and 19.6.

- the fold lines 20.4 and 20.8 of the two side walls 4 and 8 of the upper vessel Rl rest on the free edges 19.4 and 19.8 of the lower walls of the lower vessel which is possible due to the edges 23.6 ', 24.6' and 24.2 ', 23.2' in respect of; and

- steps of lower vessel Rl 28 Entering grooves 27 of upper vessel Rl.

A solid stack is formed. It should be noted that penetration of the inner portion of the upper vessel Rl adjacent to the folding lines 20.2 and 20.6 into the opening of the lower vessel Rl causes the edges 19.2 and 19.6 of this opening to open. This self-expansion is possible by stacking. However, this usually occurs in a natural way, since the load of the lower vessel R1 is pressurized by the side walls 2 and 6. In this case, self-diffusion is required.

The spillage thus obtained is further illustrated by a dashed line in the drawings of FIG. 10 and FIG. 11 to better illustrate the characterization of the present invention which is relevant to the embodiment of the present invention.

A method of realizing a wart F2 according to the present invention is illustrated in FIG. 12 and is similar to, but different from, the embodiment of wart F1 described above:

- narrow auxiliary walls 1, 3, 5 and 7 and strip not rectangular but parallelepiped;

- free edges 19.1 ', 19.3', 19.5 'opposite the fold edges 18.2 to 18.8 opposite the auxiliary walls 1, 3, 5 and 7 and the strip 16,

19,7 'and 19.16' are oblique to directly connect the free edges 19.2, 19.4, 19.6 and 19.8 without the intermediate edges 21.3, 21.5, 21.7 and 21.16 provided in the cut F1 so that the respective narrow wall projections form a rib 30;

- the free edges 22.1 ', 22.3', 22.5 ', 22.7' and 22.16 'of the folded edges 18.2 to 18.8, the narrow auxiliary walls 1, 3, 5 and 7, and the strip 16 are oblique to parallel the edges 19.1', 19.3 respectively. ', 19.5', 19.7; and 19.16 ', wherein one of said free edges 22.1', 22.3 ', 22.5', 22.7 'and 22.16' is at level 20.4 and 20.8 of the folding lines and the other projection of the latter free edges is d spaced relative to the folding lines 20.2 and 20.6, that the triangular notch 31 is formed by the fold lines 20.2, 20.4, 20.6 and 20.8, such incision being externally behind the fold lines 9, 10, 13 and 14 and having the shape 30 that they may have; and

- Free edges 32.2 and 18.6 of folded edges 18.2 and 18.6

32.6 are not linear (as illustrated in Fig. 1), but with reciprocal recesses corresponding to the free edges 19.1 ', 19.7' and 19.3 ', as well as the free edge sequence such that two successive cuts F2 may overlap slightly, which is makes it possible to save material as illustrated in FIG. 12th

Thus, in the manner described above for the cuticle FI and the vessel Rl, it is possible to realize the drawings from FIG. 13 to FIG. 17, according to FIG. 12 shown in blanks F2.

In connection with the notches 31, each wall of the vessel R2 has a triangular notch on the bottom side 1, 3, 5, 7 open to said bottom 26 as shown in larger scale in the drawings in FIG. 18, FIG. 19 and FIG. 20th

Similarly, the drawings of FIGS.

, what is said of inserting into the notch 13, fig. 21 and FIG.

Rl, it can be seen that (see full image 22) such that:

- the fold lines 20.2 and 20.6 of the two side walls 2 and 6 of the upper vessel R2 penetrate into the opening 25 of the lower vessel R2 to extend beyond the free edges 19.2 and 19.6 of the latter;

the fold lines 20.4 and 20.8 of the two side walls 4 and 8 of the upper vessel R2 rest on the free edges 19.4 and 19.8 of the two side walls 4 and 8 of the lower vessel R2, which is possible since the edges 23,6 ', 24.6', 24.2 'and 23.2 'does not reach the fold lines

20.4 and 20.8; and

- the edge 30 of the lower vessel R2 is within the triangular notches of the upper vessel R2.

In addition, the breakdown occurs in particular due to the deformation of the container by the action of its contents and, in addition, to illustrate the invention in more detail by the dashed line in FIGS. 21 and FIG. 22nd
