In this embodiment the semi-finished can also comprise a pair of support fins sides 34 and 38 joined in an articulated way to the edges outer side panels 14 and 22 respectively along the longitudinal fold lines 36 and 40.

An aspect of the invention provides about fixing means of the cover flap to close the cover after opening. Cover flap 42 is provided to cover the front face of the box. In this form of embodiment, is articulatedly attached to the outer edge of the end panel 18 along the side fold line 44. Optionally, an inner cover fin 46 is attached to articulated way to the outer cover flap 42 along its extreme edge determined by the fold line 48, in which said inner cover flap corresponds in shape with the outer cover fin.

A type of fixing means is provided by means of a pair of fixing panels 54, 56 joined together articulated with each other around the fold line 48 that can fold to determine a two-layer lug. Figure 1 illustrates a fixing panel 54 removably attached to the fin of cover 42 along the break line 50 and a panel of fixing 56 removably attached to the cover flap interior 46 along the fold line 61. Preferably, a second pair of fixing panels 58 and 60 are attached to the cover fins 42 and 46 along the break lines 52 and 63 respectively. The shape of each pair of fixing panels 54, 56 and 58, 60 determines the extreme lugs 72 and 73 that extend outward from the cover fins 42 and 46 respectively. Panels 58 and 60 are articulated together with each other. fold line length 48. Fixing panel 58 is attached to the cover flap 42 along the break line 52 and the fixing panel 60 is attached to the inner cover flap 46 along the break line 63.

From figure 1 it can be seen that the configuration of break lines 50 and 52 is different from that of break lines 61 and 63. Therefore, the fixing panels 54 and 58 comprise a projecting part 62 and panels 56, 60 they include an inclined part 64. Thus, the extreme lug 72 of the outer cover flap 42 is determined along its lateral edges along the break lines 50, 52 and it is provided with a recess and, the second extreme lug 73 that extends from the inner cover flap 46 presents its edges laterals determined by break lines 61, 63 for chamfer out at base 64 of the neck of the lug.

The construction of the box is illustrated by reference to figures 2 and 3: the inner cover fin 46 and the fixing panels 56, 60 fold first around of the fold line 48 for fixing in contact relation of faces with the outer cover flap 42 and the panels of fixation 54, 58 respectively to form a cover flap of two layers and a double layer lug 72, 73. In this form of embodiment, the fixing means are provided by a glue layer 66 applied to the outer side parts of the inner cover fin 46 and lug panels 56, 60. The cover flap 46 folds in direction A around the line fold 48 shown in figure 2.

Then the box is loaded with one or more articles so that the article is arranged on the panel back manually or by automatic machinery and the side panels 14 and 22 and side support fins 34 and 38 respectively fold inwards in direction B in relation overlay, spaced, with back panel 12, illustrated in figure 3. Next, the end panel 26 and the panel front 30 fold inward in direction C around the fold lines 28 and 32 respectively in a relationship of overlay, spaced, with back panel 12 and panel front is fixed to the lateral support fins 34, 38 by glue or other suitable means known in the art. In this way of embodiment, glue is applied to the lateral support fins 34, 38 in position 71 so that its fixation to the front panel 30

Finally, the two-layer cover flap 42, 46 and end panel 18 fold inward in direction D around the fold lines 20 and 44 respectively to form the front face of the box and panels 56 and 60 are fixed to the front panel 30, preferably, by means of glue applied to the 68 positions or other suitable means known in the art.

In this way, the box is in its finished form with an article, for example an information disc or similar retained in the holster as shown in figure 4.

The box or case of the The present invention can be shaped by a series of sequential folding and gluing operations that can be performed in a continuous production machine so that it is not required Turn or invert the box to finish its construction. The process folding is not limited to the one described below and can be altered according to particular manufacturing requirements or of the user. For example, the case could be built in part, whereby the lateral fins and the front panel are fixed each other (after folding operations B and C), before Load it with items. Alternatively, it is planned that you can supply the fully constructed box in a folded state flat with one of the side panels or ends not fixed at along one edge to provide an opening in the part side or to load the cover with the article or each item.

Figure 4 shows that it includes a cover 70 for containing information discs or the like that comprises a cover flap that can be closed again 42/46 to close the open end and a front opening of the case, said cover flap 42/46 comprising fixing means 76 removably attached to cover flap 42/46 and glued to the front panel 30. Once they have separated from the fin cover 42/46 the fixing means 76 can be coupled in new by means of the cover flap 42/46 by means of a relative displacement between cover flap 42/46 and panel front 30, as shown in figure 5.

Returning in more detail to the feature that it can be closed again from the embodiment of the present invention, represented in figure 5, the means of fixing 76 comprise a double layer fixing panel 54, 56 in the front panel 30 and, when separated, the double layer panel 54, 56 determines between its outer layer 54 and the front panel 30 a housing 78 to receive a complementary part 80 of the fin cover 42/46. It will be appreciated that accommodation 78 is determined by break lines 50 and 52 and break lines 61 and 63 respectively. Complementary part 80 of the fin of cover 42/46 is formed by the recessed part 82 and the corresponding part of sides tilted out of the layer interior 46 for reception in housing 78. Thus, cover flap 42/46 is adapted for coupling using the double layer panel 54, 56 on the front panel 30 by a relative sliding displacement between fin 42/46 and panel 30.

Returning to the second embodiment illustrated in figures 6 to 9a, there is shown a box to pack one or more items, for example for a food Frozen or chilled food products. The semi-finished 108 is formed from cardboard or a foldable sheet material similar for example plastic or similar. In the second form of embodiment, the box comprises an outer side wall panel 110, a cover wall panel 112, a second wall panel side 114, a base wall panel 116 and a wall panel inner side 118 joined together in series along the fold lines 120, 122, 124 and 126 respectively.

Said box may further comprise a structure end closure joined in an articulated way to the ends opposite sides of semi-finished 108. Each closing structure  end, in this embodiment, comprises a wall panel outer end 128 and a wall panel inner end 130 attached articulated to the base wall panels 112 and 116 respectively along the fold lines 132 and 134. In their use, the outer and inner end wall panels 128, 130 are configured to overlap when arranged in A mounted state. One or more of the extreme wall panels they can further comprise a reinforcement panel structure for join the respective end wall panel to the panel adjacent side wall. Figure 6 shows that the box can comprise a pair of reinforcement panel structures 136, 142 jointedly connected to the inner end wall panel 130 along its opposite side edges by an extension of fold lines 124 and 126 respectively.

Each reinforcement panel structure 136, 142 can comprise a pair of panels 137, 139 joined so articulated to the respective side wall panels 114, 118 at along fold lines 138 and 144 respectively. The reinforcement panels 137, 139 are joined together by a line of fold 146 oriented at an acute angle to the lines fold 124 and 126 respectively to determine panels of triangular reinforcement 137, 139. Said triangular panels 137, 139 can be folded into a face contact relationship with each other during assembly of the box.

The opposite extreme structure is substantially the same as the one described above with panels similar that are designated by the same reference numbers with the letter "a" added to the reference and therefore not It is described in greater detail.

Referring to figure 7, it shows an access fin structure that can be returned to close 148, according to a type of embodiment of the invention, which is illustrated in greater detail in Figure 6. Structure 148 preferably has two layers and comprises an outer wall formed from the side wall panel 110. The outer wall it comprises an access panel 150 and, optionally, a pair of parts outer panel 152, 154 arranged along edges opposite sides of panel 150. Access panel 150 is attached articulated to parts 152, 154 along the lines of rupture 156 and 158 respectively and is joined so articulated to cover panel 112 along the fold line 120. Part 152 is removably attached to the wall panel outer side 110 along the break line 163.

The inner wall of the access structure 148 it is provided by the inner panel 160 which is formed from a part of the inner side panel 118 and comprises a line of cut 162 relative to the free edge of panel 160, which is formed to receive the front edge of the access panel 150 of the outer wall. Said inner panel may comprise also a recess 166 formed to receive a user finger to Help your opening. The inner panel 160 is attached so frangible to the inner side wall 118 along the line of break 164. This may further comprise fixing means to fix the box access fin structure to allow Let it close again. In this embodiment, the means of fixing are provided by means of a locking lug 168 which is determined by break line 164. Closing lug 168 is oriented in a direction outside the fin structure of access 148.

The construction of the box, referring to figures 7, 8, 9 and 9a. In first place a tubular structure is formed which folds a outer side panel 110 and cover panel 112 around the fold line 120 in a substantially perpendicular relationship. Similarly, the second side wall panel 114 folds out of alignment with cover panel 112 and base panel 116 around fold lines 122 and 124 for disposal in a substantially perpendicular relationship with the panels previously mentioned. Then the wall panel inner side 118 folds in a substantially relationship perpendicular to the base panel 116 around the line of fold 126 whereby panels 110 and 118 are arranged in overlap relationship and fix each other by means suitable fasteners, for example glue or other suitable means known in the art.

As regards the fin structure of access that can be closed again, the outer parts 152 and 154 are fixed to the inner panel 160 by means of glue or other means of suitable fixation known in the art. Then you load items P at one end or each end of the box manually or by automatic machinery.

Next, the structures of extreme wall which folds the panel structures of reinforcement 136, 142; 136a, 142a around the fold lines 138, 124 and 144, 126 respectively, thereby making the inner end panels 130, 130a fold around the fold lines 134 and 134a respectively in relation substantially perpendicular. As described formerly triangular panels 137, 139 of the structures reinforcement wall fold in face contact ratio around the fold line 146 and adjoining the respective side wall, or as the inner panel 160 of the access structure

The outer end wall folds around the fold line 132 in relation to overlap with the wall inner end 130 and are fixed together by tail or other suitable means known in the art. The box is in a state fully raised, loaded, as shown in figure 7.

In order to have access to the articles contained in the box, the access fin structure that can re-closing 148 is opened by a user of the box. For open the box, the user first tears the access panel 150 pulling it out and up to separate it from the outer parts 152 and 154 along the break lines 156 and 158 respectively to discover the inner panel 160, as shown in figure 8. The panel is then pulled interior 160 in a designated outward and downward direction by the arrow X, which causes its lateral edge to separate from the side wall panel 118 along break line 164 and so that the outer part 152 is separated from the side wall panel exterior 110 along the break line 163. The line of break 164 is formed to determine a recess 167 to receive a corresponding closure lug 168 formed as an extension of the inner panel 160, shown in figure 9.

In those embodiments with a reinforcement panel structure, reinforcement panels 142a collaborate in maintaining the inner panel 160 of the structure of access flap 148 in the position shown in figure 9. Of In this way, a user has access to the items P to remove them  individually or as a group. The length of the flap that can be closed again can be altered to allow that only one item be removed at once, without departing from the scope of the invention. In order to achieve this provision, break lines 163 and 164 will move along the panels 110 and 118 respectively to increase or decrease the opening size, represented in figure 9.

To close the box again, reference is made to figure 9a in which the interior access panel 160 is folded inward in the Y direction which makes the panel reinforcement 137 folds in and towards the contact with the another reinforcement panel 139 and inner panel 160. The lug of closure 168 comes into contact with the outer reinforcement panel 110 and the inward folding action causes the lug to deform 168 and push in beyond the free edge of panel 110 to be received by the corresponding rebate 167 and be coupled in it. Next, the outer panel 150 is folds down and the front edge 169 (figure 9A) is introduced to through cut line 162 to fix the two panels between yes. It is envisaged that other suitable means may be used to removably join the outer panel to the inner panel in the access fin structure, for example queue to provide an airtight box with an access flap that can be closed from new.

A third embodiment is illustrated, referring to figures 10a, 10b and 10c in which the panels equal to those of the second embodiment are designate by the same reference number and therefore not They are described in greater detail.

Said third embodiment discloses a double locking lug arrangement with which the line of break 163 that separates the outer side panel 110 from the fin of external access 150 is formed to determine means of fixing that in this embodiment are a locking lug exterior 180 and a corresponding recess 182. Preferably, the outer closure lug 180 is offset with respect to a inner closure tab 186 shown in figure 10c. The inner closure tab 186 is similar to closure tab 168 described in the second embodiment and therefore not will describe in more detail.

Figure 10a illustrates the fin structure of access in its closed state when the box is in its state fully raised and closed. Figure 10b shows the first stage at the opening of the access structure, with which the panel of exterior access 150 separates from its adjacent exterior parts 152 and 154 and folds in a direction up and towards outside.

The next stage is to fold the panel inside 160 of the access flap out in the X direction thereby separating the locking lugs 180 and 186 from their respective side panels 110 and 118 and move out of alignment with panel 160 to get into position represented in figure 10c. It will be seen in figures 10B and 10C that the side panels comprise recesses 182 and 184 determined by forming the locking lugs 180 and 186 respectively and the closure lug 180 protruding in the recess 182 to engage with a part of the side wall panel inside 118 and thus prevent panel 160 from being pushed inward beyond panel 118. Thus the structure of access fin can be maintained in a substantially relationship coplanar with adjacent side wall. To close the access fin folds first the inner panel 160 in upward and inward direction similar to how it described above so that the lug of the inner closure 186 be pushed under the side wall panel outside 110 for coupling with recess 184. Next the outer panel 150 is fixed to the inner panel 160 as it has been described above to close the box again.

Figures 11, 12 and 13 illustrate a fourth form of embodiment of the invention that is substantially the same as the second embodiment and therefore numbers are used of equal reference with the addition of the number "2". Box it is constructed similarly to the second embodiment although, in this example, there is no panel structure of reinforcement to form the end panels and the side panel 218 form the outer side wall by providing the side wall interior by panel 210. Thus, it will be appreciated that the inner and outer panels 250, 260 of the fin structure of Access have been reversed. Again, the outer parts 252 and 254 they are fixed to panel 260 but in this embodiment to the face inside by glue or other suitable means known in the technique.

To open the access fin structure, you fold outer panel 260 in an upward direction and toward outside Z that causes it to separate from the rest of the box along break line 264. This action also makes the panel interior 250 separates from its adjacent exterior parts 252, 254 along the break lines, so that it is free to be folded in a downward and outward direction and as it shown in figure 13. In this embodiment, the lug closure 268 is formed from an extension of the part exterior 252 and can be folded out of alignment with respect to the same during the opening and closing of the access flap by interfering with the panels that form the wall side, to thereby make the outer panel 260 engage With the side wall. In this embodiment, the panel interior 250 is fixed to panel 260 by fixing means adequate. It is envisioned that the inner panel 250 can be fixed to the outer face of panel 260 when closed again without thereby departing from the scope of the invention.

Advantageously, in the fourth embodiment it is made that during the opening of the outer panel 260 take place a single tearing action, instead of two tearing actions separated as is the case in the first embodiment.

The fifth embodiment of the invention is illustrated in figures 14, 15 and 16 showing a shaped box from semi-finished 308 of cardboard or of a sheet material Similar folding to contain one or more items. The construction of semi-finished 308 is illustrated with reference to Figure 14 in which said semi-finished comprises a panel of inner side wall 310, one end wall panel 312, one panel opposite side wall 314, an opposite end wall panel 316 and an outer side wall panel 318 attached so articulated together in series along the fold line 320, 322, 324 and 326 respectively. Said semi-finished comprises also a panel structure to form the lid and the base that it is substantially identical and therefore reference is made only to the panels that form the lid.

Said box comprises a first wall panel of lid 328, a gluing fin 330, a second wall fin of lid 332, a glue flap 334 and a flap wall flap outside 336, each of them configured in an adjacent position to the next and jointly attached to the panels that form the side parts and the ends along the line of fold 338. In this embodiment, panels 328, 332 and 336 are sized to overlap in order to provide a closed lid wall.

The box can also comprise a panel of inner support 340 extending from the inner side panel 310 to provide a double layer structure for one part from the side wall. Along the fold line 346 you can be glued together to panel 340 a gluing fin 342

In the lid wall and the upper parts of the lateral and extreme walls is formed a structure of access fin 380, shown in Figure 15. Said structure of access fin 380 is determined in part by the line of break 348 that extends through the side panels and ends 310, 312 and corresponding to the break line 356 that extends through the side wall 318 and the end wall 316. Said access fin structure further comprises the line fold 354 extending through panel 314: crossing its ends with break lines 348 and 356 respectively. From this mode when the box is formed, the break lines 348, 356 and the fold line 354 form an endless fold line.

Said box may further comprise means of fixing that in this embodiment are provided by a locking lug 358 and a recess to allow it to close the access fin structure again. In this form of embodiment, the locking lug 358 is attached so articulated to the side wall panel 318 along the line of fold 360 and is separated from it by a cutting line 362 which determines the edge of the recess. Optionally, the box comprises in addition a second locking lug 350 joined together in an articulated manner to side panel 310. In this embodiment, the lug of closure 350 is off center with respect to the first lug of closure 358 to provide fixing means and allows the upper and lower parts of the side and end walls are coupled again by sliding relative.

In order to build the box, this conforms by the first folding panels 310, 312, 314, 316, 318 around the fold lines 320, 322, 324 and 326 to form a tubular structure, whereby the side wall panels interior and exterior 310 and 318 overlap, at least in part, and are fixed to each other by suitable fixing means, by glue example or other suitable means known in the art. Optionally, support panel 340 and gluing fin 342 they are fixed to the inner face of the outer side panel 318 and of the end panel 316 respectively. Then, the items at the top or base of the box using a relative displacement

Next, the lid and base are formed with which folds the outer panels 328, 336 around the fold line 338 in overlapping relationship with the panel inner wall 332 and are fixed thereto along the fins of glued 330 and 334 respectively. In this way the box is in a raised and loaded state represented in figure 15.
