HIGH RESISTANCE BOX TO OPENING

Description

VI99 A 0 0 00 3 5 PALLADIO Industria Tipo 1 itografica SpA. Description The invention relates to a box, made of cardboard or other flexible material, shaped in such a way as to present a high resistance to opening. It is well known that, in particular in packaging sectors such as, for example, the pharmaceutical sector, boxes must guarantee the integrity of the product, that is, they must ensure that they have not been opened before a certain time, which normally corresponds to the first use of the bottle contained therein. This entails the need to produce boxes equipped with devices capable of unequivocally highlighting tampering resulting from an attempt to open the box itself. The purpose of this invention is to create a box, made of thin cardboard or other flexible material, which once closed, which happens when packaging the product, such as for example a bottle, in addition to having a high resistance to opening, can only be opened following significant tampering, which leads to the tearing of a portion of said box, resulting in easily identifiable by the user or by whoever must guarantee the integrity of the packaged product. This is achieved by providing for the realization of a box made of thin cardboard or other flexible material equipped with two flexible tabs, one obtained on the folding edge of the closing panel or lid and the other on the main panel or external wall and such that when the box is in the closed condition said two tabs are superimposed. The two overlapping tabs have a substantially equal profile and each is equipped with two opposing protrusions, preferably shaped like a cusp. The novelty of the invention consists in the fact that the distance between the ends of the two opposing protrusions, in practice between the two vertices of the cusps present in the external tongue (the one obtained on the main panel or external wall of the box) is slightly greater than the distance between the ends of the two opposing protrusions, in practice between the two vertices of the cusps, present in the internal tongue, i.e. the one obtained on the folding edge or lid. In practice, therefore, we obtain that the overall dimensions lateral of the external tongue is greater than to the lateral width of the shaped opening created by punching the internal tab and this cutting line is precisely what prevents accidental or abnormal opening of the box. This is possible because after the box has been closed, the operator, with light pressure, folds the two overlapping tabs inwards. Since the profile of the external tongue is larger than the profile of the aforementioned shaped passage opening, created on the folding edge of the lid, when said external tongue is pushed towards the inside of the box, it initially deforms slightly and then, once it has passed the aforementioned opening created on the folding edge of the lid, it springs elastically back into its normal position, that is, it returns to being stretched, thus positioning itself in contact with the internal surface of the aforementioned folding edge. In this way, a safety hook is created since to open the box, i.e. to lift the lid, it is necessary to overcome the reaction of the external tongue folded inside until it finally breaks, being the same unable to exit from the opening within which it was previously inserted. Such characteristics of the I found they are better highlighted by the description a its possible form of embodiment, made for information purposes only for illustrative and non-limiting purposes only, with the help of of the attached drawing tables where: - fig.l CTav.I) represents a plan view of the sheet of cardboard used to make the box referred to in the invention, after the die-cutting phase; - fig.E represents a perspective view of the box mentioned in the finding, in the open position; - fig.3 (Table II) represents a perspective view of the box mentioned in the finding, in the closed position; - fig.^ represents a detailed view of the two folding tabs only overlapping; - fig.5 represents a lateral section view according to line VV of fig.^; - fig.6 represents a detailed view of the two overlapping folding tabs folded inwards, - fig.7 represents a lateral section view according to the line VI-VI of fig.6. With reference to fig.1, in the cardboard are obtained four main panels or walls 1, 2, 3 and 4 consecutive, separated from each other by folding lines 5, 6, 7, 8, parallel to each other; the panel is separated, by the folding line 8, from a flap 9 intended to be glued inside the panel 1 when the box is shaped in such a way trad i ztonale. From the ends of the main panels protrude flaps 10, 11, 12, 13 and closing panels 14 and 15, all separated from the main panels by fold lines 16 and 17, perpendicular to fold lines 5-8. From each of the closing panels 14 and 15, intended to form the lids or bottoms of the box, separated by the folding lines 18 and 19 respectively, protrude the folding flaps 20 and 21 respectively, intended to be inserted and retained inside the opposing main panels 2 and 4 respectively in the packaged and closed box. The structure of the cardboard and the box that can be obtained with it, described so far, is the traditional one of most boxes. As visible in fig. 2, the realization of a box, with high resistance to opening and inviolable, except following serious tampering, is obtained by providing on the free ends 28 and, respectively, 23 of the two main panels 2 and 4-, the presence of two tabs 2^ and respectively 25 and further providing in correspondence with the lines of folding 18 and, respectively, 19 of the folding flaps 20 and, respectively, 21 the presence of two tabs 26 and, respectively, 27. The arrangement of the aforementioned tabs is such that, when the box is closed, two pairs of overlapping tabs are formed; the tabs 22 and, respectively, 23 of the front panels match the tabs 26 and 27 respectively located on the folding flaps (see fig.3> The profile of the four tabs 22, 23, 26 and 27 is similar, but the tabs 22 and 83, arranged externally, have a slightly larger overall size than the corresponding adjacent tabs 26 and 27, arranged more internally in the closed box. Specifically, as visible in fig.^ and 5, each tongue is provided with two opposing protrusions, 28, shaped preferably in a cusp shape and the distance between the ends of the two opposing ones protrusions, in practice between the two vertices of the cusps present in the external tabs 22 and 23 respectively, those obtained on the main panels or external walls of the box, is slightly greater than the distance between the ends of the two opposing protrusions, in practice between the two vertices of the cusps, present in the internal tabs, i.e. those obtained on the folding edges. This means that, since the profile of the external tongue, 22 and, respectively, 23, is larger compared to the profile of the 1st shaped opening 29, resulting from the die-cutting of the internal tab, 26 and 27 respectively on the folding edge of the lid, when said external tab is pushed towards the inside of the box slightly and, subsequently, shaped opening, then returns to rest on the aforementioned folding edge, as desired (see figs.6 and 7). Obviously, there are possibilities other than the one illustrated only with the lid equipped with the ; without however coming out first it deforms beyond the aforementioned to stretch, going to the internal surface of the realizing the hooking of the embodiments for example providing a closure as per the finding, from the scope of the patent claims.
