Detailed description of the embodiments preferential

In reference to the drawings and, in particular, to Figure 1, we show an elongated die 10 made of cardboard or of functionally similar sheet material comprising, in series, a first assembly to form a cover 12 comprising a panel of fixing 14, an inner cover panel 16, an edge panel 18, and an outer lid panel 20 articulated each to the next at along the transverse fold lines 22, 24 and 26 respectively. In one type of embodiment, the set of cover 12 also includes a tongue 28 that facilitates the opening and the closure of the lid assembly during use.

The cover assembly 12 is articulated to the first side wall panel 30 along the fold line transverse 32, the side wall panel 30 is articulated to a base panel 34 of the main body of the cardboard container at along a transverse articulation line 36. Preferably, the side wall panel 30 has a pair of closing legs of end 38 and 40 articulated to panel 30 along the lines of longitudinal fold 42 and 44 respectively.

The base has, at each of its ends opposite end panels 46 and 48 that are joined together folding to the main base panel 34 along the lines of Longitudinal fold 50 and 52 respectively. End panel 46 procures a lock panel 54 that is fixed to panel 46 at length of the longitudinal fold line 56. The locking panel 54 includes a rectangular retract element 58 to supply a part of the stop means to the covers, described in more detail later. Similarly, at the opposite end of the panel base, end panel 48 is provided by a panel of lock 60 that is articulated to panel 48 along the line with longitudinal fold 62. Locking panel 60 also includes a rectangular retract element 64 to supply a part from the stop to the covers.

The die assembly on the opposite side of the base panel 34 is similar to that adjacent to fold line 36 in which there is a second side wall 30 'that is articulated to the base panel 34 along the transverse fold line 36 '. Preferably, the side wall 30 'is provided, in each one of its opposite ends, by a closing end panel 38 ' and 40 'articulated to the side wall panel 30' along the longitudinal fold lines 42 'and 44' respectively.

In this embodiment, the rest of the die comprises a second cover structure 12 'that includes a fixing panel 14 ', an inner cover panel 16', a panel edge 18 'and an outer cover panel 20'. 14 'fixing leg it is articulated to the inner cover panel 16 'along the fold line 22 ', the edge panel 18 is fixed to the panel inner cover 16 'along the fold line 24' and is articulated to the outer cover panel 20 'along the line of cross fold 26 '. The outer cover panel is connected to the side wall panel 30 'along the fold line transverse 32 '.

The die assembly to form the body shown in Figure 6 is relatively simple as it is illustrated in Figures 3 to 5 respectively.

In Figure 3 it can be seen that bands of G adhesive (shown in shading) are applied on each of the side wall panels 30 and 30 'and therefore, such and As shown in Figure 4, the lid panels bend following the transverse fold lines 24 and 24 'in one riding ratio on the base panel 34 of the die such that the fixing legs 14 and 14 'are fixed with the adhesive on side wall panels 30 and 30 ' respectively, as shown in Figure 4.

The die can then be assembled in its three-dimensional shape, folding the end panels 46 and 48 and the side wall panels 30 and 30 'up from the panel base and then the end fixing legs 40, 40 ', they bend inwards towards each other of the same so that the end closure legs 38, 38 'fold towards the inside through the ends of the body. Panels lock 54 and 60 are then folded along the lines of fold 56 and 62 respectively in a riding relationship with the end wall panels inside the die such and as shown in the left end of Figure 5 (the end right of figure 5 shows the open end of the right body before being closed) and can be fixed by a means of appropriate fixation known in the bouquet. Cardboard body assembled with the closing caps seen in its open position it shown in figure 6.

Referring to figure 2, the element inserted 64 is a simple cardboard or cardboard structure corrugated comprising a base panel 66 having panels of side walls 68 and 70 fixed thereto along the lines of  Longitudinal fold 72 and 74 respectively. Panels end 76 and 78 are fixed to the opposite end edges of the base panel 66 along the transverse fold lines 80 and 82. The inserted element is formed by simply folding the side and end panels in the same direction outside the plane of the base panel 66 to create a box with opening in the upper part. The element inserted with opening in the part upper is then simply snapped in place in such a way that the base, the side walls and the end walls of the inserted element are placed in a face riding relationship face to face with base, side and body end panels main thus seeking a multipliegue structure to accommodate a fragile item like a glass container. In certain modes of embodiment, the end wall panels 54, 60 are maintained is its place by the inserted element where panels 54, 60 are located between the end wall panels 46, 48 and panels 76, 78 respectively.

The body with opening in the upper part such and as shown in Figure 8 it can be closed by articulating the two closing caps towards each other through the top open body

When the covers open fully, the interior and exterior wall panels are practically in flat face contact, so that the body content It can be removed at the desired time for use. Without However, when the covers are articulated towards their closed position, the inner and outer lid panels are separated from each other to form, for each of the caps, a section structure of hollow box B (Figure 9). This provision is possible because of the offset ratio between the fold line 22, 22 ', on the which the inner cover panel 16, 16 'is articulated to the panel of fixation 14, 14 'and the fold line 32, 32' on which the outer cover panel 20, 20 'is articulated to its side wall respective 30, 30 '. So, when the covers are completely open, the edge panels 18, 18 'are practically in the same plane as its attached inner lid panel 16, 16 'but, in the moment when the cover panels are brought into position closed, the edge panels 18, 18 'are separated from the outer panel 20, 20 and the inner and outer cover panels 16, 16; 18, 18 they separate to the point where, when the doors are fully enclosed, interior and exterior cover panels they are separated as much as they can be, that is, by the width of the edge panels 18, 18 'themselves and the box sections They are thus completely assembled.

In the closed position, of course, the edge panels of the respective doors are carried to a close relationship to face to face in the center of the body.

In order to ensure that the doors receive an aid to remain in their closed position, each of the inner cover panels 16, 16 'has locking projections "p" (Figure 1) that are introduced under the created locking edge by the retracted elements 58 and 64 of the lock panels 54 and 60
respectively.

The tongue 28 formed from the panel of outer lid of the lid assembly 12 is brought to a ratio of riding with the other cover set 12 'when the covers They are in their closed position.

So, when the carton is closed, the doors form a protective barrier for the container crystal, together with the multi-body in which the Article is introduced. However, the carton can be easily open to access your desired moment content and remove it without removing the packaging material and this then provides a convenient packaging for the consumer but tear resistant.

The present invention and its embodiment preferential refer to a provision to supply a structure with an access to open and close in a cardboard container completely closed. However, it is provided that the invention can be applied to a variety of packaging to transport items and that she is not limited to those of the type completely closed described above and that can be used for numerous applications, for example, a cardboard container envelope

It will be noted that directional references used in the present text such as "top", "base", "end", "side", "inside", "exterior", "superior", and "inferior" do not limit the respective panels to a certain address, but serve only to distinguish these panels from each other. All reference to an articulated connection should not be interpreted as necessarily referring to a single fold line: indeed, it is provided that the articulated connection may be formed by one or more than one line of the following lines: a line of points, a dashed line or a fold line, without moving away of the framework of the invention.

It should be noted that many changes can be made within the framework of the present invention, for example the dimensions and shape of panels and openings can be adjusted to accommodate items of different dimensions or shapes, and alternative closure structures can be used in the top or base. The carton can accommodate more of an article in different rows.
