In reference to the drawings and, in particular, to Figure 1, we show a die 10 formed of cardboard or of a similar folding sheet material to form a cardboard box completely closed to be used to pack a plurality of items in a row. The die comprises a plurality of panels to form the top, the opposite sides and the ends and the base of the cardboard box.

In this embodiment, there is a first panel side wall 12, an end wall panel 14, a second side wall panel 16, a second end wall panel 18 and a locking tab 20 connected in an articulated manner one to the next in series along the fold lines 22, 24, 26 and 28 respectively.

There are also some upper wall structures and base wall to form the top wall and the base wall respectively. The upper wall structure comprises a first upper wall panel 53 connected in an articulated manner to the  side wall panel 16 along the fold line 55 and a second upper wall panel 54 connected in an articulated manner to the first side wall panel 12 along the line of fold 56.

The base wall structure is built from the first base wall panel 58 connected in one way articulated to the first side wall panel 12 along the fold line 62 and the second base wall panel 60 connected in an articulated manner to the side wall panel 16 along the fold line 64. The outer edges of the wall panels of base 58 and 60 are respectively provided with parts P1 and P2 They are adapted to fix each other.

There are also grip tabs 67 and 68 connected in an articulated way to the first and second panels of respective base wall 58 and 60 along the fold line 66 and 70 respectively. The support tabs are formed by the first support tab 72 connected in an articulated manner to end wall panel 14 along the fold line 74 and a second support tab 76 connected in one way articulated to the second end wall panel 18 along the fold line 78.

The lockout arrangement for the cardboard box of the present invention is formed by a locking flap and an opening arrangement where there is one or several flaps 80 that they extend from the upper wall panel 53. The flap 80 comprises opposing withdrawal elements 82 to define a part of support to come into contact with the corresponding edge of an opening defined in part by the cutting line 84. The part female of the locking arrangement is, in this invention, created by the opening formed when the second upper wall panel 54 is folded along the fold line 56.

There is also the division structure used to separate adjacent items contained within of the cardboard box. The division structure is created by a arrangement in end wall structures. Every wall of end 14, 18 is created by interior oriented panels that They are located in the middle of adjacent items. So the wall end 14 comprises a first partition panel 30 and a second split panel 32 connected to each other in an articulated manner along the fold line 34 and the first and second panels of respective side walls 12 and 16 along the lines of fold 22 and 24. There is also a support panel 36 connected of a mode articulated to the first and second division panels 30 and 32 along the fold lines 38 and 40.

Similarly, the end wall 18 it comprises a first division panel 42 and a second panel of division 44 connected to each other in an articulated way along the fold line 46 and the second side wall panel 16 and the fixing tab 20 respectively along the lines of fold 26 and 28. There is also a support panel 48 connected of a mode articulated to the first and second division panels 42 and 44 along the fold lines 50 and 52.

The support panels 36 and 48 are designed to keep the partition panels in the desired shape that, in This embodiment is a band shape. Obviously, the support panels may be formed in a different way according to the desired shape of the dividing part, for example, curvilinear or strophoidal.

There may also be one or more windows of exposure 94 at or in each side wall panel 12, 16. Of optional mode, a partition cross panel 90 is formed to from, and connected in an articulated way to the wall panel side 16 along the fold line 92 to define a exposure window The cross partition panel 90 is used to separate adjacent rows of items.

In order to form the entire container in flattened state from the die, a series of operations sequential bending and gluing are necessary and will be better described in reference to Figures 2 to 6 of the drawings. Bending and gluing operations can be carried out on one or several linear machines, so that it is not you need to turn or reverse the tray to complete your building. The folding procedure is not limited to what is described below and can be modified according to particular manufacturing needs.

A first stage of construction is to apply glue on locking tab 20 illustrated by strokes crossed and referenced by the letter G. The end wall 18 and the locking tab 20 are folded along the line of fold 26 in a face contact relationship with the panel side wall 16, shown on Figure 3. Next, the side wall panel 12 folds along the line of fold 22 to be placed in a face contact arrangement with the end wall 14 and is fixed on the tongue of fixing 20, as shown on Figure 4. The wall of base is partly built by folding the support tabs 72, 76 inward in a face contact relationship with the end walls 14, 18. The base wall panels 58, 60 are fold inward along the fold lines 62, 64 so that the grip tabs 67, 68 are brought to a face contact relationship with support tabs 72, 76 respectively and fix each other. In this way, the box of cardboard is in flattened state ready to be supplied to a End user for final construction and loading.

In order to complete the construction of the cardboard box, opposite side wall panels and panels Opposite end wall of the carton are folded out of face contact arrangement along the lines fold 22, 24, 26 and 28 to form a tubular structure.

This folding action makes the structure of base wall forms automatically, which makes the support tabs 72, 76 and grip panels 67, 68 are fold down what, in turn, makes the first and second Base wall panels fold outward. The parts on projection P1 and P2 act as a retention stop and then they are taken to look at each other in a provision of riding

In these embodiments with a panel of cross partition 90, the panel folds inwards at along the fold line 92 before the introduction of Items inside the cardboard box.

Items are loaded by a relative vertical movement between the cardboard box and the articles, as is well known, and the wall is formed higher. The inner upper wall panel 54 folds toward the inside along the fold line 56 to reveal a opening formed partly by the cutting line 84. The panel of upper outer wall 53 folds inward along the fold line 55 and the lock flap 80 folds so which is inserted into the opening where it is fixed. For this medium, the inner and outer upper wall panels 54 and 53 are fixed together in a face contact relationship.

The locking action of the flap 80 that is insert the side wall panels into the opening force opposites 12 and 16 towards each other, which causes the dividing part In this embodiment, the dividing part is shape by folding inward the partition panels 30 and 32 and 42 and 44 along fold lines 34 and 46 respectively. In these embodiments with the panel support, the split panels also fold along the fold lines 38, 40 and 50, 52 to be folded in one angular arrangement relative to support panels 36 and 48, as shown on Figure 6.

The edges of the defined dividing parts by the fold lines 34 and 46 are located at the point interior of the dividing part to separate adjacent items  thus improving stability and limiting unwanted movement inside the container
