DESCRIPTION

REINFORCED DIE-CUT CORRUGATED CARDBOARD CONTAINER, AND

PALLETIZED STRUCTURE THAT INCLUDES SAID REINFORCED CONTAINER

TECHNIQUE SECTOR

The technical field of the present invention is semi-rigid containers of polygonal cross section, for example, boxes, cardboard containers, formed by folding paper-based sheets.

OBJECT OF THE INVENTION

The object of the present invention is a reinforced container comprising a body obtained with a single band of die-cut corrugated cardboard. The body comprises an upper mouth, at least partially open, delimited by upper parts of side walls of the body, configured to support one or more sets of reinforced container and stacked pallet, and the body also comprising a bottom, at least partially open, configured to be supported on a pallet, the bottom being formed by the union of lower flaps connected to the lower part of at least four side walls by lower horizontal folds.

BACKGROUND OF THE INVENTION AND TECHNICAL PROBLEM TO BE RESOLVED

On the one hand, document ES2653920A1, from the same inventor as the present application, proposes a large reinforced container, that is, with a base width of 60 centimeters or more and a height of 90 centimeters or more, to be supported on a pallet. . The reinforced container is made of several pieces: a flat base piece folded and attached to a tubular body 61. The flat base piece is daisy-shaped, and is formed from the union of a plurality of flat pieces: a bottom center and a plurality of wall panels joined at their ends to the central bottom, extending radially. The base flat piece is made of a plurality of separate cardboard flat pieces in order to take advantage of the higher compressive strength of the corrugated cardboard in the same direction as the corrugated corrugated cardboard grooves.

On the other hand, document ES2717723A1, from the same inventor as the present application, concerns a reinforced body made of several pieces: a first body and a second body made of corrugated cardboard, with lower and upper open mouths. Both bodies are joined together by adhesive that joins the inner lateral contour of one body with the outer lateral contour of the other body, by linearly introducing one body inside the other according to a relative linear movement parallel to the axis of vertical symmetry of the bodies.

On the other hand, document EP3616896A1, by the same inventor as the present application, proposes a reinforced polygonal drum made of glued corrugated laminar material. The drum comprises two pieces of cardboard: a tubular body and a base body. The polygonal tubular body includes a band made of at least one corrugated sheet and one flat sheet joined together, for example, single-sided corrugated cardboard, rolled at least two full turns, and a base body of single-walled corrugated cardboard in background functions that completely closes the background of the body. Depending on the number of complete turns, a multilayer wall is obtained with a desired number of smooth and corrugated sheets, that is, a container with personalized mechanical resistance to compression and expansion that is easily manufactured, and with a low-cost raw material such as simple cardboard. expensive. Said drum is for containing bulk products, to replace the classic plastic or metal drums, particularly steel drums, with volumes typically between 200 and 1250 liters.

On the other hand, document ES1276909Y9 proposes a reinforced container made from several sheets of rigid corrugated cardboard: a first sheet 40 for the formation of the body, and one or more second sheets 60 to laterally reinforce the container on at least two side walls. of the body facing each other. The body has a lateral contour formed by four or eight serrated side walls, four lower flaps 52, 53 that arise from the side walls and define a bottom, and some upper flaps attached to the side walls from which they arise that determine a reinforced upper mouthpiece. .

On the other hand, document ES1274749U, from the same inventor of the present application, proposes a palletized structural assembly for the transport and handling of fruit and vegetable products, where, instead of having a single stack of mutually nested boxes on the same pallet in a container of a road vehicle, the palletized structure comprises a single structural stack including a plurality of pallets, wherein each pallet supports a plurality of boxes limited in number to two or three boxes, and wherein each tray is made from a single flat cardboard development of five sheets joined together, three smooth sheets, and two corrugated sheets sandwiched between the smooth sheets.

The document ES2169629A1 discloses a reinforced container 1 comprising a rectangular body with a partially open upper mouth and four tubular struts 4 located in the nooks or corners of the body to support the vertical efforts, when stacking a container full of merchandise one on top of the other, and to stabilize the body avoiding undesirable deformations due to the flexibility of the semi-rigid material - preformed folded die-cut corrugated cardboard plate - with which the body is made. In the corners of the body, pairs of cuts 8 (Fig. 1) are made that delimit some sectors of material diverted towards the interior of the container that form clamps in these corners. 9 orthogonal to keep the struts 4 upright. In each corner, openings 5 folded into the sectors displaced towards the inside of the container, reveal parts of the struts 4 that serve as support and sliding surface for tensioning and closed by some straps or bands 3 that surround the container 1, ensuring stability and avoiding deformations due to expansion efforts of the side walls of the body of the container. The stability and the mitigation of the expansion strain are avoided thanks to the fact that the straps 3 are not located in the four edge portions of the corner of the rectangular body, but are located in each corner or three straps 3 are located in correspondence with three openings 5 of the clamps 9 equidistant (Fig. 2).

On the other hand, document US4874125A proposes a rectangular cardboard box (Fig. 8) with a bottom closed by four lower flaps and an upper lid also closed by upper flaps, which originate from the bottom and top of four side walls, which define together a rectangular closed box.

In said document US4874125A, the cardboard box is obtained with a single single-wall corrugated cardboard sheet, with two smooth sheets and one corrugated sheet sandwiched between the smooth sheets (Figs. 3 and 7).

However, this same document US4874125A describes that, instead of increasing the compressive strength by modifying the construction of the corrugated cardboard using a double-walled or triple-walled cardboard structure, the invention proposes, on the contrary, moving away from this alternative, elements cardboard reinforcement that can be formed with the single cardboard sheet, extending the height of the cardboard box, and positioned at the corners of two adjacent side walls. Thus, the reinforcing elements are folded (Figs. 2-3 and 6-7), forming either a double-walled multilayer reinforcing element in contact with the long side walls (Figs. 3 and 8), or a L-shaped double-walled multilayer reinforcing element in contact with both the long and short sidewalls (Fig. 7).

On the other hand, document ES1172234U, considered the closest antecedent, proposes a reinforced container comprising a body obtained with a single band of die-cut corrugated cardboard, the body comprising an upper mouth, at least partially open, delimited by upper parts of some side walls of the body, and the body also comprising a bottom, at least partially open, the bottom being formed by the union of bottom flaps connected to the bottom of at least four side walls by bottom horizontal folds.

In document ES1172234U, the reinforced container is made of cardboard, without specifically selecting a specific cardboard from among a wide variety of types of cardboard, and comprises five pieces in combination: a body obtained with a single corrugated cardboard sheet, and four column elements 300 which are struts or tubular elements. The body has a rectangular side contour of four serrated side walls, and has braces, called inner channels 115, 116, 117, defined by partially cut fold lines at the corners of the container body. The clamps serve to position the column elements 300 inside the body of the reinforced container.

On the one hand, a drawback of reinforced containers to contain large volumes is that they must offer high mechanical resistance to both vertical compression and expansion, as well as buckling, as well as a minimum manufacturing cost: raw material cost ( development from cardboard to plate) and cost of assembly of the container from the plate, depending on the manual, automatic assembly or partially manual and partially automatic assembly of the container.

A drawback of the currently used reinforced containers, for example, of the type such as the aforementioned ES1172234U, is that their mechanical resistance to compression and/or expansion and/or buckling is severely limited, and they also exhibit intolerable deformations due to the semi-rigid nature of the cardboard. what they are made with

This limited mechanical resistance produces that, for the transport of certain products, for example, a wide range of fruits and/or vegetables, the height of the container is typically limited to about 60 centimeters.

Another drawback is that, for the transport of certain products, for example, a wide range of fruits and/or vegetables, each structural assembly of pallet and reinforced container on pallet is only generally stacked at two heights, although for container measurements, the container and pallet sets can be stacked three heights, to avoid frequent losses of the contained product due to the poor mechanical resistance of the reinforced containers.

These double-height stacking practices are very frequent and common for a wide range of fruits and/or vegetables, for example, for the transport of melons and watermelons, and a very considerable part of the volume of the container of the land transport vehicle is empty, Said empty transport volume is of the order of 33.33% and only the remaining 66.66% is usually occupied with cargo, undesirably increasing the transport costs of containers full of product.

Also, this non-optimized transport with empty transport volumes of product, results in an increase in the cost of the carbon footprint (polluting emissions) of each kilogram of product transported in the reinforced container.

Another drawback of reinforced containers formed from several parts is that their assembly cost is considerable. In addition, the logistics and storage of such a large number of parts is complex and has associated costs related to storage, stock management, etc.

It would be desirable to obtain a versatile reinforced container that offers high mechanical resistance at the same time as a minimum cost, both a minimum manufacturing cost and a minimum cost of placement at the point of sale, reducing the carbon footprint per kilogram of product contained in the container. reinforced container, transported and placed at the point of sale.

EXPLANATION OF THE INVENTION

In order to solve the drawbacks described in the previous section, the present invention presents a reinforced container that comprises a body obtained with a single band of die-cut cardboard.

Corrugated cardboard is a material that has the advantage of being recyclable and also with a reduced biodegradation time, compared, for example, with the high biodegradation times of plastic materials, including extruded or molded plastic materials, or metallic materials.

In addition, corrugated cardboard is attractive for its lightness, compared to containers reinforced with plastic or metal bodies.

The body comprises an upper mouth, at least partially open, delimited by upper parts of side walls of the body, configured to support one or two structural assemblies, forming a stack of two or three structural assemblies, each structural assembly comprising a single pallet. and only one or two reinforced containers supported on said pallet at the same height.

The body further comprises a bottom, at least partially open, configured to be supported on a pallet. The bottom is formed by the union of lower flaps connected to the lower part of at least four side walls by lower horizontal folds.

The at least partially open mouth and the at least partially open bottom have the advantage of providing a minimum development of cardboard for the only band constituting the body, minimizing production costs of the reinforced container, while maintaining the structural resistance of the reinforced container configured to form part of a set of a single pallet and only one or two reinforced containers supported on said pallet at the same height during transport.

In addition, the body has a lateral contour formed by at least twelve flat side walls arranged around the bottom, and each folded perpendicular to the bottom.

The at least twelve planar sidewalls include two mutually facing first sidewalls, two mutually facing second sidewalls, and at least eight smaller sidewalls.

The at least two of said smaller side walls are sandwiched between each first side wall and each second side wall in each of the four corner areas of the body.

Likewise, in the body, the at least twelve flat side walls are connected one after the other, in series, by at least twelve mutually parallel vertical folds.

Furthermore, in the body, each side wall is laterally delimited by two vertical folds, and two of said mutually end side walls of the folded band are joined, preferably by a joining end side panel.

The folded band constituting the body is made of double-walled corrugated cardboard, with only five sheets: three smooth sheets and two corrugated sheets arranged between two of the smooth sheets.

In the folded band constituting the body, the two corrugated sheets have a different corrugation amplitude from each other, and the two corrugated sheets form vertical grooves, perpendicular to the bottom, in the at least twelve side walls, to reinforce the compression resistance of the reinforced container. .

In the reinforced container, the choice of the structure of said double-walled corrugated cardboard, of only five sheets, has the advantage of providing an optimal ratio between the mechanical resistance of the container and that which requires a minimum development of the strip surface with which the body is obtained, also making it possible to easily produce the strip in conventional corrugated cardboard installations, both due to development measures and cardboard structure, at reduced costs.

In the reinforced container, the intentional direction of the grooves of the two corrugated sheets provides a high compressive strength to the reinforced container, that is, to support vertical loads.

Also, in the reinforced container, each side wall and each vertical fold of the body, has a continuous vertical extension that extends from the bottom to the upper mouth, to reinforce the reinforced container in vertical compression and radial expansion.

The continuity of the side walls and the vertical folds significantly increases the compression and expansion resistance of the container, and decreases the deformation of the side walls of the container under stress in the stacked situation.

In other words, in the reinforced container in a stacked situation, the continuity of the side walls and folds ensures that the compression forces are transmitted between the upper mouth and the bottom of the reinforced container, distributed by the reinforcement points, like pillars of cardboard, which form said reinforcing smaller side walls and said vertical folds.

Thus, in the present invention, it will be understood that the vertical folds have an extension corresponding to the height of the container, the folds not having tucks or gaps.

Thus, in the present invention, it will be understood that the side walls include at least some continuous vertical sectors from the bottom to the upper mouth.

Preferably, some side walls, in addition to the aforementioned continuous vertical sectors, may also include ventilation holes for the product to be contained in other sectors of some of the side walls.

Likewise, in each corner zone, the at least two smaller side walls are folded by the at least three vertical folds towards an interior volume of the body, to reinforce the reinforced container in vertical compression and expansion.

These at least two folded smaller side walls and the at least three vertical folds positionally delimit, at least partially, at least one free space of the body arranged in each corner zone, each free space having a continuous vertical extension from the bottom to the mouthpiece. superior.

Thus, these at least two smaller side walls and vertical folds in each corner area act as a structural pillar. These pillars are advantageously formed from parts of the band constituting the body itself, not from separate pieces, thus minimizing the manufacturing costs of the container, including a simplification of stocks that results in lower manufacturing costs.

These at least two smaller side walls in each of the four corner areas are of less width than the first and second side walls, to provide these structural pillars in the corners strategically, while the development on the surface of the cardboard is minimal to optimize production costs.

Also, said at least one free space of each corner area is arranged adjacent to and on the outer side of the inner volume of the body.

Said interior volume is laterally enclosed by an interior lateral contour of the body defined by a plurality or all of the at least twelve side walls.

That is, the interior volume of the body enclosed by the side contour may be defined by a subset of the at least twelve side walls or by all of the at least twelve side walls.

In the reinforced container, the free spaces optionally allow the arrangement, in each free space of each corner zone, of a respective optional, elongated column element, additional to the body, which has a vertical extension that extends from the bottom to the upper mouthpiece.

In other words, the reinforced container may or may not include said column elements, depending on the load requirements to which the reinforced container will be subjected, for example, according to the needs of the order: product to be contained, handling conditions, and/or storage and/or transport, etc.

When the reinforced container comprises said column elements, preferably, each of said column elements is a slender piece of constant cross section, either of a closed cross section or of an open cross section with a V or L shape, etc.

In the event that the reinforced container comprises said column elements, these are preferably made of cardboard or several sheets of paper joined together, that is to say, of a material with several superimposed layers of paper, thus including corrugated cardboard, laminated cardboard / compact, cardboard cardboard, among others.

Alternatively, the column elements can be made of plastic, preferably extruded or injection molded.

Thanks to the provision in each corner area of at least two smaller side walls folded by at least three vertical folds, which extend continuously from the bottom to the upper mouth for a distance corresponding to the height of the reinforced container, the mechanical resistance of the reinforced container is increased, for example, before stacking, and the deformations due to the flexibility of the semi-rigid material (double-wall corrugated cardboard) are reduced, avoiding the collapse of the reinforced container in a stacked situation.

The twelve vertical folds act as vertical pillars of increased resistance, both in compression and expansion. The increased resistance to expansion and the lower deformation of the side walls under expansion stresses is due to the fact that, thanks to the at least twelve vertical folds and at least twelve side walls, in the lateral contour of the body, the linear distance between adjacent folds is reduced, for example, compared to a reinforced container with a rectangular side contour.

Optionally, the clearances contribute to increased versatility in mounting the optional column elements to the body, should column elements be required. For example, when the column elements are arranged in the reinforced container, the free spaces and the at least two flat minor side walls and vertical connecting folds between flat minor side walls provide the possibility of arranging column elements with a wide range of shapes: triangular, rectangular, circular section, in V in L, etc.

That is, depending on the transport needs, for example, the type of product to be contained and/or the type of shipment (by land, sea and/or air), the reinforced container offers the possibility of having a respective column element, elongated, additional to the body, which has a vertical extension that extends from the bottom to the upper mouth, to optionally adapt the resistance of each reinforced container to each order: conditions of the product to be contained, handling, storage, and/or transport .

Preferably, the corrugated cardboard strip constituting the body is a single die-cut sheet that includes a plurality of panel sectors connected one after the other, in series, the side walls of the body being formed by said panel sectors.

This preferred option maintains all the advantages related to improved resistance, while optimizing the manufacturing costs of the container, by using a single blank blank to obtain the body of the reinforced container.

Optionally, in the band, the plurality of panel sectors includes at least twelve panel sectors: two major sectors, two intermediate sectors and at least eight minor sectors, the at least twelve panel sectors being connected to one another, one after the other, in series, by respective weakened vertical lines stamped, parallel to each other, which define the at least twelve vertical folds in the folded body that connect some side walls with others.

In another option, the corrugated cardboard band constituting the body consists of several plates die-cut with end panels of each plate joined together. In the band constituting the body, each of the plates comprises a plurality of panel sectors, the side walls of the body being formed by the plurality of panel sectors of the plates.

This band option made up of several plates has the advantage of simplifying the production, and therefore the production costs, of reinforced containers with a development of considerable measurements, for example, those reinforced containers with measurements such that their internal volume covers at least least 80% of the plan surface of a pallet measuring approximately 1,000 x 800 millimeters or approximately 1,000 x 1,200 millimeters.

Preferably, in the reinforced container, each of the vertical extensions of the at least twelve side walls, each of the vertical extensions of the at least twelve folds, each of the vertical extensions of the four free spaces of the corner zones , and/or each of the optional column elements, have an equal vertical dimension between 500 and 1200 millimeters, to reinforce the compression-reinforced container and to enable the stacking of two or three palletized structural assemblies, each palletized structural assemblage comprising one or two reinforced containers supported at the same height on a respective pallet.

That is, thanks to the reinforcement provided by the structural pillars formed by the at least two smaller side walls and at least three vertical folds in each corner area, the reinforced containers:

- They do not have a height - distance between bottom and upper mouthpiece - limited to about 60 centimeters, said distance being any one between 50 and 120 centimeters, or even more; and

- The containers can be stacked in palletized structural assemblies both two and three heights, one on top of the other, each reinforced container being supported on a respective pallet.

For example, the reinforced containers of the present invention can be stacked in two palletized structural assemblies, each container having a height of 100 centimeters, and also the reinforced containers of the present invention can be stacked in three palletized structural assemblies, each container having a height of 60 centimeters.

Thus, the volume occupied in transport containers is increased, reducing the carbon footprint per kilo of product transported, and the cost can be optimized associated with the development of cardboard (cardboard band) needed per kilo of product transported.

In one option, in the reinforced container, each corner zone includes two smaller side walls, arranged diagonally with respect to the adjoining side walls or forming a right angle to each other arranged on the outer side of the interior volume of the body.

The diagonal or straight angulation of this option improves the compressive strength of the container, and increases the resistance of the container and its deformation in the face of lateral forces applied to the reinforced container, for example, during its handling, storage and/or transport. , which causes side-to-side movement of the sidewalls known as swaying.

In another option, each corner area includes two smaller side walls that form a right angle arranged on the outer side of the inner volume of the body.

The right angle of this option further improves the compressive strength of the container, and increases the resistance of the container and its deformation against both transverse and longitudinal lateral forces (in two mutually perpendicular horizontal directions) applied to the reinforced container, for example , during its handling, storage and transport, which causes side-to-side movements of the side walls (swaying).

In case the container includes such column elements, the right angle makes it possible to arrange a wide range of column elements in different shapes.

Thus, for example, the right angle favors the placement of column elements with a triangular cross section, L or V-shaped cross section, square cross section, square cross section, cylindrical tube cross section, among others, whether these options are with hollow or solid interior.

In the event that the container comprises first and/or second optional folded top flaps, described below, the right angle favors that the lateral end portions of these top flaps abut reliably on surface portions or flat edges, in order to increase the lateral resistance of the reinforced container.

In one option, in the reinforced container, each corner area includes at least two smaller side walls in contact forming a multilayer wall comprising at least one double smaller side wall.

In one option, in the reinforced container, each corner zone includes at least three side walls in mutual contact forming a multilayer wall comprising at least a triple lesser lateral wall.

The multilayer walls reinforce the structural resistance of the container with a minimum addition of material to the development in the surface of the body, minimizing cardboard costs.

In a preferred option, in the reinforced container, each corner area comprises only two smaller side walls, folded by three vertical folds, towards the internal volume of the body, forming a twelve-sided body with an outer and inner lateral contour.

This preferred option optimizes an improved mechanical resistance of the container with a minimal surface development of the band constituting the folded body of the reinforced container, saving raw material and production costs.

In the event that the reinforced container includes the optional column elements, this preferred option also simplifies and facilitates the arrangement (assembly) of the column elements in the free spaces of the reinforced container, due to improved accessibility to the free spaces, reducing time assembly, reducing manufacturing costs of the reinforced container.

Optionally to the previous preferred option, in each corner area, the only two smaller side walls form a right angle to each other.

In another option, in the reinforced container, each corner area includes a multi-layer wall arranged diagonally with respect to the adjacent side walls, forming a body with an octagonal inner lateral contour with a multi-layer chamfer of at least triple minor side walls in each corner area. .

In another option, in the reinforced container, each corner area comprises six smaller side walls folded by vertical folds, towards an interior volume of the body. In addition, three minor side walls are in contact with each other forming a multilayer lateral minor triple wall, and another three minor side walls are in mutual contact forming another multilayer lateral minor triple wall, one multilayer forming a right angle with the other, and forming a twelve-sided outer and inner lateral contour body.

According to another option, in the reinforced container, each corner zone includes four side walls in mutual contact forming a multi-layer wall comprising a quadruple smaller side wall. In addition, the multilayer wall is arranged diagonally with respect to the adjoining side walls, partially delimiting two acute-angled free spaces in each corner area, forming a body with an external lateral contour of twenty-four sides and an inner contour of sixteen sides.

According to another option, in the reinforced container, each corner area comprises three smaller side walls folded by vertical folds that delimit a free space of triangular cross section. In each corner zone, on the hypotenuse side of the triangle, the multi-layer wall is arranged, comprising two smaller side walls in contact with each other, forming a double smaller lateral wall. In each corner zone, one leg of the triangle is bounded by a smaller side wall, and the other leg of the triangle is bounded by an end portion of a side wall. The body forms a rectangular outer side contour and an octagonal inner side contour with a chamfer in each corner area.

According to another option, in the reinforced container, each corner zone comprises six smaller side walls folded by vertical folds that delimit a free space of rectangular cross section. In each corner zone, on each of the two contiguous sides of the rectangle forming a right angle, a respective multi-layer wall with double minor side wall is arranged, and on each of the other two sides of the rectangle forming a right angle, a respective wall is arranged minor lateral, forming a body with a rectangular outer lateral contour and a dodecagonal inner contour.

According to another option, in the reinforced container, in each corner area, the at least one free space is partially delimited laterally by the lateral contour, the free space being accessible by the outer side of the lateral contour of the body, to make it possible to arrange each element column according to a lateral movement perpendicular to the plane where the bottom is contained.

This option simplifies and facilitates the arrangement (assembly) of the column elements in the free spaces of the reinforced container, due to improved accessibility to the free spaces, reducing assembly times, and reducing manufacturing costs of the reinforced container.

Preferably, in each corner zone, the at least two smaller side walls and the at least three vertical folds are immobilized at their lower and/or upper ends by parts of the strip constituting the body.

Thus, the container offers improved resistance to compression and/or expansion and/or bending both in storage conditions and in handling and transport conditions.

According to the previous preferable option, in each corner zone, a lower part of the lower flaps cooperates with a lower part of the smaller side walls to serve as a transverse and/or longitudinal lower immobilization stop for the smaller side walls.

In a first variant of the previous option, in each corner zone, said lower part of the lower flaps includes at least one lateral cut line of the lower flaps adjacent to a lower part of the smaller side walls.

In a second variant of the previous option, in each corner zone, said lower part of the lower flaps includes at least one cavity of the lower flaps into which a lower part of the smaller side walls corresponding to a lower projection of the lower flaps is introduced. side walls.

Preferably, in the reinforced container, the upper mouthpiece comprises first folded upper flaps, by upper horizontal folds perpendicular to the vertical folds, and joined to the upper part of at least two mutually facing side walls.

Optionally, in the reinforced container, the upper mouthpiece comprises second upper flaps, folded by other upper horizontal folds, and joined to the upper part of the other two mutually facing side walls. In addition, in the reinforced container, each first and/or second upper flap comprises a horizontal shelf flap for stacking support and/or an end flap for joining the upper flaps to the side walls.

Thus, the at least partially open upper mouthpiece is reinforced with high resistance to expansion in at least two mutually facing side walls.

Optionally, in the reinforced container, each first and second top flap further comprises a horizontal shelf flap for stacking support. In addition, each first and second upper flap also comprises an end flap for joining the upper flaps to the side walls.

Thus, the at least partially open upper mouth is reinforced, in the face of expansion and compression forces, in the upper part of the two first and two second side walls.

Preferably, in the reinforced container, in each corner zone, at least part of a lateral end of a first and/or second top flap is adjacent to at least one of the smaller side walls to serve as a longitudinal and/or transverse top stop. of the lesser lateral walls.

Optionally, in each corner zone, at least part of a lateral end of a first and/or second upper flap is in contact with at least one of the smaller lateral walls.

Thus, this upper longitudinal and/or transverse stop is adjacent in such a way that it reinforces the pillar formed by the smaller side walls and vertical folds in each corner of the container, under longitudinal and/or transversal load stresses due to handling and/or transportation, this stop of each corner being in contact with the smaller side walls, keeping in position the pillars formed by the parts of the body itself, parts such as the smaller side walls and the vertical folds of the corner areas.

Preferably, in the reinforced container, in each corner area:

at least part of a lateral end of a first top flap is adjacent to a smaller side wall to serve as a longitudinal top stop for the smaller side walls, and

at least part of a lateral end of the second upper flap is adjacent to another smaller side wall to serve as a transverse top stop for the smaller side walls.

Thus, this double upper limit, longitudinal and transversal, in each corner area, reinforces the pillar formed by the smaller side walls and vertical folds in each corner of the container, and under both longitudinal and transversal load stresses due to handling, and /or storage, and/or transport, this double stop at each corner remains in contact with a respective minor side wall, keeping in position the pillars formed by parts of the body itself, parts such as the minor side walls and the vertical folds of the corner areas.

Preferably, in each corner zone, an upper part of the first and/or second upper flap cooperates with an upper part of the smaller side wall to serve as an upper immobilization stop for the smaller side walls.

Optionally, in each corner zone, the upper part of the first and/or second upper flap includes at least one upper recess, in which an upper projection of the side walls is immobilized by interlocking.

Complementarily, in each corner zone, the upper lateral extension of the shelf flap of the first and/or second upper flap cooperates with an upper part of the smaller side wall to serve as an upper immobilization stop for the smaller side walls and to delimit free space above.

Optionally, in each corner zone, the at least two smaller side walls and the at least three vertical folds are immobilized at their lower and upper ends. by respective parts of the constitutive band of the body.

DETAILED DISCLOSURE OF PREFERRED EMBODIMENTS

In the figures, the reference 40 designates generically the reinforced container (40) of the first aspect of the invention.

In the following, express reference is made to the figures of the first embodiment of Figs.

1 to 8, although these features are common to all embodiments, unless otherwise stated.

The Figs. 6 and 8 show that the reinforced container (40) comprises a body, obtained with a single band (20) of die-cut corrugated cardboard shown in Fig. 1.

The Figs. 6 and 8 show that the body comprises flat side walls, a top mouthpiece, and a bottom.

The upper mouthpiece is at least partially open and is delimited by upper parts of the flat side walls of the body.

In the specific case of the embodiments of Figs. 1-18, an upper punched cut line (17) delimiting the upper parts of the side walls, once folded into folded cut lines (57) delimit the upper open mouth of the reinforced container (40).

The upper mouth is configured to support a stacked reinforced container (40) and pallet (70) assembly, in the three-high stacks of Figs. 32, 33 and 36.

The upper mouth is configured to support two sets of reinforced container (40) and stacked pallet, in the two-high stacks of Figs. 30 and 34.

The Figs. 2, 3, 6 and 8 show that the body further comprises a bottom, at least partially open. The bottom is formed by joining lower flaps (47, 48) connected to the lower part of at least four side walls by respective lower horizontal folds (49).

Thus, in Fig. 1, the only band (20), which corresponds in this specific case to a single die-cut plate (10), with weakened fold and cut lines, the bottom is formed by folding the two lower panels (8 ), in this specific case larger, and two lower panels (7), in this specific case smaller, around the respective lower weakened horizontal lines (9) punched, becoming larger lower flaps (47) and smaller lower flaps (48). perpendicular to the side walls of the body, folded around the respective lower horizontal folds (49), as shown in Figs. 6 and 8.

The Figs. 30 to 36 show that the bottom of each reinforced container (60) supported on a respective pallet (70).

Common to all embodiments, for example, Figs. 6 and 8 show that the body has a lateral contour formed by at least twelve flat side walls of the body arranged around the bottom and perpendicular to it, forming a cross section closed traverse.

Common to all embodiments, following in Figs. 6 and 8, the at least twelve side walls include two mutually facing first side walls (44), two mutually facing second side walls (45), and at least eight smaller side walls (46).

Continuing in Figs. 6 and 8, the at least two of said smaller side walls (46) are sandwiched between each first side wall (44) and each second side wall (45), in each of the four corner areas of the body, each area being corner delimited by a respective first and second side wall (44, 45).

In the body of the reinforced container (40) of Figs. 6 and 8, the at least twelve flat side walls are connected one after the other, in series, by at least twelve vertical folds (42) parallel to each other. Furthermore, each side wall is laterally delimited by two vertical folds (42).
