Description

OPERATION AREA

The invention relates to a container for receiving goods of any kind, especially goods that can be managed by electronic means.

STATE OF THE ART

There are countless container types for goods known, even as a box shape. They differ because of the material they are made of, their mass and construction details.

Among these, those made of cardboard are particularly popular because of their light weight, sufficient strength, low cost and recyclability.

Some containers also have the advantage of being stackable. This facilitates storage before, during and after the transport of goods.

Among the containers, one type provides the presence of protrusions protruding from the uppermost portion of their vertical side walls. Such upper projections engage in cavities whose shape and dimensions are compatible with the sinking or pinching and realized at the base of the vertical side walls. The projections and the slots are coplanar.

WO 2004/087512 A1 describes one of these containers. It includes a base surface, end panels that protrude from the opposite end of the base surface, and side panels. Lateral edges are connected to the end panels and extend parallel to the side edges of the base surface, but slightly inwardly with respect to said side walls. The sheet is punched so that blocking tabs and cavities for receiving the blocking tabs of a container on which it is stacked.

EP 0 863 081 A1 describes another container of this type. This container is equipped with tabs and cavities. The tabs protrude from the upper side and engage in the slots of another container which is stored on the container to achieve good stack stability. Of course, other arrangements are possible to provide stability to a stack of stacked containers, for example, in a configuration where the tabs are active for a greater length of the corresponding side (e.g., greater number or longer tabs) and do not interfere with the bottom slots of the container placed thereon but block the ground therebetween.

However, the goods transport technology provides for the use of more and more electronic means for detecting each individual container and controlling its movements.

The laser readers are part of this electronic means. Some of these provide for the continuous and automatic reading of at least one vertical container sidewall, i. H. by the one who has the most important data of the goods contained therein. Unfortunately, the above-mentioned cavities in the lower edge of the vertical sidewalls cause a disruption or discontinuity of the reading process with the interruption of the system or with the generation of false data, with the conceivable consequences.

SUMMARY OF THE INVENTION

The invention has for its object to provide a container without slots on the lower sides of the vertical side surfaces in order to solve the above problem.

Another object is to provide a box container having at least one slot for insertion of an easily removable information label.

The objective stackable container created from the stamped sheet solves these and other tasks. It contains a front panel or wall, a base panel or wall, at least one rear panel or wall and side panels or walls. The base panel is connected along fold lines to the at least one front panel, to the at least one rear panel and to the side panels.

The front panel is connected along fold lines to a first side edge and to a second side edge. The rear panel is connected along further fold lines to a first side edge and to a second side edge.

From the upper side of each of the at least two panels or walls, at least one upper flap is formed during the punching process. Each upper flap is formed along a cutting line. Each upper flap is coplanar with the panel or wall from which it was formed.

In the lower part of each of the at least two panels, at least one lower flap along or at the cutting line and one fold line are obtained in the punching process.

Said fold lines are parallel to the fold lines between the panel from which each lower Tab was formed, and the lower panel, and extend in the base panel itself.

In use, the box container is assembled by assembling its different parts. During these operations, the upper flaps remain coplanar with the panels from which they extend. The lower flaps already cut along the cut lines are folded along the corresponding fold lines which extend into the base panel. Each lower flap extends parallel to the panel from which it is received, but displaced in the direction of the container inside with respect to this panel.

The space left free from the folding of each lower flap with respect to the panel from which the flap is obtained has dimensions compatible with that of the upper flap. This free space forms a seat for receiving the upper tab of a second container and thus allows the stacking of multiple containers. The dimensions of the seat correspond to those of an upper flap or sufficient for locking the upper flap in this seat. Such seats are located under the upper flaps.

But even if the container here is not stacked, no cavities are present at the base of the vertical side walls, since the lower tabs close the seats to the inside of the container. The laser readers can thus perform a correct reading.

In the slot between each lower tab and the panel from which the tab is obtained, also an easily removable information label can be inserted.

Detailed Description of a Preferred Embodiment

With reference to the u. a known box container for goods is realized with a punched cardboard sheet or blaff.

With particular reference to The known container has the shape of a parallelepiped and comprises a front panel 1 , a basic panel 2 , a rear panel 3 and two side panels 4 . 5 ,

The front panel 1 is along a first horizontal fold line 6 with a front side edge or strip 7 along a second horizontal fold line 8th with the base panel 2 along a first vertical fold line 9 with a side edge or strip 10 and along a second vertical fold line 11 with a second side edge or strip 12 connected.

The front margin 7 is along a third vertical fold line 13 with a side edge or strip 14 and along a fourth vertical fold line 15 with a second side edge or strip 16 connected.

The basic panel 2 is along a third horizontal fold line 17 with the rear panel 3 , along a fifth vertical fold line 18 with the side panel 4 and along a sixth vertical fold line 19 with the side panel 5 connected.

The rear panel 3 is along a fourth horizontal fold line 20 with a rear edge or strip 21 along a seventh vertical fold line 22 with a side edge or strip 23 and along an eighth vertical fold line 24 with a second side edge or strip 25 connected.

The front edge 21 is along a ninth vertical fold line 26 with a side edge or strip 27 and along a tenth vertical fold line 28 with a second side edge or strip 29 connected.

To the front part of the front panel 1 becomes a square tab during the punching process 30 formed in middle position in the front edge 7 extends. The tab 30 has longer baselines parallel to the first horizontal fold line 6 up and along a first cut line 31 receive.

From the front panel 1 , near the base panel 2 , the punching process becomes a first square area 32 away. This has longer baselines parallel to the second horizontal fold line 8th on and is in center position along a second cut line 33 that completely surrounds him. The second cutting line 33 has a respect to the Basispaneels 2 slightly inside page.

From the back panel 3 , next to the base panel 2 , the punching operation becomes a second square area 34 away. This has longer baselines parallel to the third horizontal fold line 17 up and in middle position along a third cutting line 35 that completely surrounds him. The third cut line 35 has a respect to the Basispaneels 2 slightly inside page.

In the back part of the rear panel 3 becomes a second tab during the punching process 36 formed with square shape, located in central position of the front edge 21 extends. The second tab 36 has longer baselines parallel to the fourth horizontal fold line 20 up and down along a fourth cut line 37 receive.

When used, both edges are 10 . 12 of the front panel 1 perpendicular to this along the first and second vertical fold line 9 . 11 folded. Likewise, in use, both edges are 23 . 25 the rear panel 3 perpendicular to this along the seventh and eighth vertical fold lines 22 . 24 folded.

The front panel 1 and the rear panel 3 are therefore rectangular with respect to the Basispaneels 2 along the second and third horizontal fold lines 8th . 17 folded.

The two side panels 4 . 5 are perpendicular to the base panel 2 along the fifth and sixth vertical fold lines 18 . 19 folded. The two side panels 4 . 5 thus touching the lateral edges 10 . 12 of the front panel 1 and the two side edges 23 . 25 the rear panel 3 ,

Thus, the lateral edges 14 . 16 the front edge 7 perpendicular to this along the third and fourth vertical fold lines 13 . 15 folded. Likewise, the side edges 27 . 29 the rear edge 21 perpendicular to this along the ninth and tenth vertical fold lines 26 . 28 folded. Finally, the front edge 7 and the back edge 21 perpendicular to the front panel 1 and to the back panel 3 along the first horizontal fold line 6 and the fourth horizontal fold line 20 folded.

The lateral edges 14 . 16 thus touching the side panels 10 . 12 of the front panel 1 , and the side edges 27 . 29 touch the side panels 23 . 25 the rear panel 3 ,

During these operations, they are in the front part of the front panel 1 located flap 30 and those in the back of the back panel 3 located flap 36 that go along the first cut line 31 and the fourth cut line 37 are pre-cut, in the upper part of the front panel 1 and the rear panel 3 , and indeed coplanar with the same front 1 and rear 3 Panels.

By removing the areas 32 . 34 from the front panel 1 and the rear panel 3 Two cavities form 38 at the base of the front panel 1 and the rear panel 3 , with dimensions those of the upper flaps 30 . 36 correspond. The upper tabs 30 . 36 are located vertically above the cavities 38 ,

When the known container is placed on another container, the upper tabs slide 30 . 36 of the lower container into the cavities 38 of the upper container and thus allow their perfect stacking.

Regarding to The container according to the present invention has essentially the same components.

However, he has a third square tab 39 during the punching process in the front panel 1 is realized and located near the base panel 2 located. The third tab 39 becomes along a fifth cutting line 40 and a tenth horizontal fold line 41 receive. The fifth cutting line 40 the third tab 39 is laterally wider or more expansive compared to the second cutting line 33 the known area 32 , As a result, the tenth horizontal fold line extends 41 more inside the base panel 2 ,

A fourth square flap 42 becomes in the punching process in the rear panel 3 is realized and is located near the base panel 2 , The fourth tab 42 becomes along a sixth cutting line 43 and an eleventh horizontal fold line 44 receive. The sixth cutting line 43 of the fourth tab 42 is laterally wider or more expansive compared to the third section line 35 the known second area 34 , As a result, the eleventh horizontal fold line also extends 44 more inside the base panel 2 ,

During the folding process, the lower flap 39 of the front panel 1 and the lower flap 42 the rear panel 3 that already along the fifth line of intersection 40 and the sixth cutting line 43 are cut in the direction of the base panel 2 until they move along the tenth horizontal fold line 41 and the eleventh horizontal fold line 44 wrinkles. The lower tabs 39 . 42 extend parallel to the plane of the front panel 1 and the rear panel 3 , but shifted to the inside of the container with respect to the front 1 and rear 3 Panels.

The because of the folding of the lower tabs 39 . 42 from the front panel 1 and the rear panel 3 in the direction of the container interior vacant spaces have dimensions corresponding to those of the upper flaps 30 . 36 on and form seats 45 for holding the upper tabs 30 . 36 a second container. The upper tabs 30 . 36 are located vertically above the seats 45 ,

When the subject container is superimposed on another container, the upper tabs engage 30 . 36 of the lower container in the seats 45 of the upper container and thus allow their perfect stacking.

However, even if the container herein is not stacked, there are no cavities at the bottom of the vertical side walls because the bottom flaps 39 . 42 the seats 45 close to the inside of the container. This allows for correct reading by the laser readers.

The stackable container thus developed can be subjected to many other changes and variants, which are part of the inventive concept. All items are interchangeable with other technically equivalent ones as well.
