Description

Box with bag for illustrative leaflet.

This invention relates to a box formed of a single piece of cardboard, which has an inner bag for accommodate a sheet, illustrative leaflet, or the like.

Many items are housed, preserved, and transported in boxes or carriers made of cardboard. With frequency, illustrative leaflets or similar are inserted also inside these boxes. The most frequent case is that in the that the items inserted in those boxes are containers of several kinds, multi-material jars, pill bubble containers or capsules containing pharmaceutical products; in this case, the leaflet illustrating said product must necessarily be present in the box in which the bottle, container, or Similary.

In the known technique, the boxes are produced by specialized companies, and the pharmaceutical industry inserts directly the jars or the like inside those together with The illustrative prospects. This operation is relatively laborious and slow, especially as a result of difficulties found in the insertion of the leaflet (often large dimensions and folded several times) inside the box, in such a way which still allows said bottle to be freely inserted without It is wrinkled.

Documents DE-U-8618368 and EP-A-0911266 show boxes that they have an inner bag to accommodate an illustrative leaflet, separate from jars or other items that can be inserted or removed separately from the box. Inside each of said boxes protrudes a fin that on one side Longitudinal is rigid with one of the side walls main of the box, whose fin is facing a wall main different from the same box to form with it said bag to accommodate the leaflet. Since you can't make that said fin rotate freely in the box (as this would prevent Automatically introducing any item within the box), its free end is folded 90º around itself to form a tongue that is fixed (glued) to the side wall adjacent main box, whose fin divides the cavity of the box in two different longitudinal parts similar to each other, and the free upper edge or side of the fin (perpendicular to its sides longitudinal) will thus produce interference with certainty Items that are introduced in the box.

Therefore, the main purpose of this invention is to provide a box formed of a single piece of cardboard, which has inside a bag in which the leaflet be inserted directly by the manufacturer of said box, and the recipient of this one simply has to insert the article (bottle, etc.) intended to be contained within said box.

Another object is to provide a box of the type cited, in which the prospectus is retained, adhered with safety to the interior surfaces of the box, so that it just allow that item to be inserted easily and fast inside it by the user of the box.

Another object is to produce a box in which the illustrative leaflet can be inserted easily and quickly by the box manufacturer, directly
during the stages of her formation.

These and other objects are achieved by a box formed from a single piece of die cut cardboard and with marked fold lines, or the like, comprising:

- at least four main panels consecutive;

- a fin protruding from the first of said main panels, whose fin is superimposed and glued on the last of the main panels of the finished box;

- at least two panels to close the two ends of the box, and protruding from the ends of at least one of the main panels, whose main panels and said fin are separated from each other by fold lines parallel longitudinals, and whose closing panels are separated of the main panels by transverse fold lines substantially perpendicular to said fold lines longitudinal; and where since the last of said panels main protruding a supplementary panel separated from that by a fold line parallel to said fold lines longitudinal, and the width of the supplementary panel is smaller than the total width of the two main panels consecutive to said supplementary panel, which is divided into two parts by one intermediate fold line parallel to said fold lines longitudinal, and whose supplementary panel is folded into the box around the fold line that separates it from said panel the main protrusion, and also partially folded around to said intermediate fold line, such that each of the two parts of the supplementary panel face a respective one of the main panels, to form a bag inside the box to accommodate said illustrative leaflet;

- and characterized in that the free edge longitudinal end of the supplementary panel can freely interfere with the adjacent inner surface of the panel main consecutive to the main panel in front of said part of the supplementary panel, and because said bag to house the leaflet is formed between the supplementary panel and the two main panels that remain in front of him.

Preferably, said fold line intermediate supplementary panel, and also the fold line which separates it from said last main panel, comprises some cutouts made in cardboard and spread from a limited part of the length of said fold lines.

Again and preferably, a part of the end of said pair of supplementary panels that is directly connected to said last main panel, it is glued to the Inner surface of the main panel facing.

Finally and advantageously, in at least one of the two main panels remaining in front of said panel supplementary, an open window is arranged in a position corresponding to said bag, to allow a part of the illustrative leaflet inserted into said box bag be seen from the outside.

The structure and characteristics of the box are they will appreciate better in the following description of an embodiment of it, which is presented as a non-limiting example and with reference to accompanying drawings, in which:

- fig. 1 is a plan view of a piece cardboard extended, stamped and with fold lines marked, usable to form a box, and whose figure shows the surface of the cardboard to be inside said box;

- figs. 2 to 5 show the cardboard piece of fig. 1 in its successive folding operations to form the box;

- fig. 6 is a perspective view of the box finished with its upper lid open, with a part of the box omitted to allow a clearer view of its interior:

- fig. 7 is a cross section extended to through the box, taken on line 7-7 of the fig. 6; Y

- fig. 8 is similar to fig. 7, but shows a different arrangement of the folded panels inside the box.

First reference will be made to fig. 1, which It shows an extended piece of cardboard stamped and with the lines of marked fold, seen from its inner side, that is, the side opposite to the one on which the writing visible from The outside of the finished box.

The cardboard piece comprises four panels consecutive main 1 to 4, and a fin 5 protruding from the first of the main panels, that is, from panel 1; said panels and fin are separated from each other by lines of 6 to 9 parallel folds. From the two opposite ends of the panel main 3 project two closing panels 10 (separated from the main panels by transverse fold lines 11, perpendicular to the fold lines 6 to 9) intended to form the lid, and respectively the base of the box. From the sides opposite of the main panels 2 and 4 also protrude folding side pieces, which for simplicity purposes have not been numbered

The structure of the cardboard piece described So far it is totally traditional.

The characteristics of the cardboard piece illustrated in the drawings is that since the last of the panels main, that is, panel 4, a supplementary panel protrudes 12A, 12B separated from said panel 4 by a fold line 13 parallel to lines 6 to 9. The supplementary panel is divided into two parts (12A and 12B, respectively) by means of a line of intermediate fold 14, also parallel to lines 6 to 9.

In the drawings (and in particular in fig. 3) it can be seen that the total width of the supplementary panel 12A, 12B is less than the total width of the two main panels 3, 4 consecutive to that, so when the supplementary panel is folded over the two panels 3,4, the two fold lines 9 and 14 they will not overlap each other while the free edge longitudinal part 12B of the supplementary panel is parallel but slightly separated from the fold line 8 (as can be seen in particular in fig. 3).

Preferably, along the lines of fold 13 and 14 of the supplementary panel there are some cutouts short longitudinal 15, 16 respectively, which facilitate the fold of said supplementary panel around said lines 13, 14.

Also preferably, the panel length Supplementary 12A, 12B is less than the length of the panels main 1 to 4 faces in the folded box, and the upper edge of the supplementary panel is profiled, that is, defined by an arc line (see figures), or in any case not perpendicular to lines 6 to 9, in order to facilitate the insertion of a bottle (or other item) into the box completed

Finally, in the drawings it can be seen that in the main panel 3 there is arranged a window 17 (which could also extend to panel 4 and could be obtained by detachment of a knurled part of the panel), with a window 18 also provided in the supplementary panel, whose presence of Such windows may be useful but not strictly necessary.

Suppose now that the manufacturer you have tried the cardboard from which the die-cut cardboard sheet has been produced and with the marked fold lines of fig. 1, folds then to form the box to be sent to the recipient her.

In a first operation, a leaflet Illustrative 19 already printed and folded on itself, is located automatically on the main panels 3, 4, and a glue a point 20 is applied to panel 4 (fig. 2). The panel supplementary 12A, 12B, is then folded back over the two panels 3, 4, so that said illustrative leaflet 19 remains interposed between the two main panels and the superimposed panel (fig. 3), forming between them an open bag at its end higher. The cardboard sheet is also folded along the line of fold 8, so that the supplementary panel rests on the inner surface of panels 1, 2, and two glue bands 21 are applied to the outer surface of the main panel 4 (fig. 4). It will be appreciated that the glue bands applied to the panel 4 could be just one, or also, the glue could cover The entire inner surface of the panel.

Finally, the cardboard sheet is folded in around the fold line 6, to superimpose the flap 5 on the main panel 4 and fix it to it by means of said glue (fig. 5).

All the operations described above can be carried out quickly and easily by the factories of cardboard treatment that produce traditional boxes, with the use of automatic machines commonly used by such factories

The purpose of window 17 is to leave without cover, and visible from the outside of the box, a part of the illustrative leaflet 19, on which a code can be printed of identifier bars of said leaflet. Window 18 allows verify the presence of the illustrative leaflet even if the box finished be open only by its lower end. The company recipient, who receives the box already glued and folded as shown in fig. 5, then use the automatic machines normally used to form the box and close the panel base, while leaving the top panel or lid open, then of which the article intended to be inserted into said box stayed in it. For example, if the target company produces Pharmaceutical specialties, the item that is inserted in the box It can be a bottle (not shown in the drawings).

Since the operation of inserting the bottle inside the box can be carried out at high speed by known techniques, the aforementioned company has the great advantage of not having to also insert the illustrative leaflet into said box (as is the case today), and not having to extreme the care to prevent said bottle (during insertion into the box) interferes with the leaflet, deforming or wrinkling it.

With the use of the box of the invention, when it is pressed to pass from the condition of fig. 5 to that of fig. 6, the supplementary panel automatically folds towards outside around its intermediate fold line 14 (by interfering with the longitudinal free edge of the supplementary panel with the surface adjacent inner panel 2), to form the bag containing the illustrative leaflet, which can be easily extracted from the box holding it by its top, where it is free by the edge of the supplementary panel, as can be clearly seen in fig. 3, and especially in fig. 6.

The curved or sloped top edge of the panel supplementary also facilitates the insertion of said bottle in the box, preventing the aforementioned bottle from wedging against this edge free of supplementary panel.

The box represented in fig. 7 has a substantially square cross section, but it is obvious that said section may be rectangular, in which case some of the panels will be larger than others.

Fig. 8 is very similar to fig. 7 (and for the purpose for simplicity the same numbers of reference) and differs from the second in that in a simple way and essential the supplementary panel has been folded inwards, in such a way so that parts 12A and 12B of said supplementary panel remain in front of panels 1 and 2, respectively, of the box. In this case, part 12A of the supplementary panel can be glued preferably on the inner surface of panel 1, and the leaflet 19 can be retained between panels 1, 2, and the parts 12A, 12B of the supplementary panel.
