Description

Semi-rigid material packaging with indicator of inviolability.

The present invention relates to a packaging of the box type with flaps, or with flaps and lid, of a material semi-rigid such as cardboard or corrugated cardboard, comprising a inviolability indicator.

US 449 265 and EP 0 519 389 describe packaging of this type.

Currently, one faces acts every time criminals, which aim at packages sent by mail or by courier, which are open during transport, emptied of its content, and close again with more or less care, before Get empty to your recipients.

These recipients, if they do not pay attention to package they receive, they open this one, they discover that it is empty and then, with all their good faith, they reproach the sender for not having them delivered the expected merchandise.

The invention wants to solve this problem, in the case of box-type packaging that includes flaps external and internal flaps, articulated by fold lines on the walls of the packaging, or also internal flaps adjacent to two opposite walls and a pivotally mounted lid with respect to one third wall, and proposes to provide the packaging with an indicator of inviolability, which, without knowing the individuals who have fraudulently opened the packaging, it shows from the outside of this one the fact that it has been violated and allows for this mode to its recipient reject it without opening it when receives.

To this end, the invention aims at a Packaging of a semi-rigid material, such as cardboard or cardboard corrugated, comprising this packaging:

-

     side walls adjacent to each other by fold lines parallel;

-

     at least a bottom portion adjacent to at least one of said walls;

-

     two sheets called internal flaps, articulated in the part top of two opposite walls by fold lines perpendicular to the previous ones and apt to be folded perpendicular to said walls;

-

     two sheets called external flaps, articulated in the part upper of two other walls perpendicular fold lines to those of the internal flaps, in order to be folded over the latter, or also an articulated cover on another wall by a folding line perpendicular to those of the internal flaps, to in order to be folded over the latter;

-

     a locking means in the folded position of the outer sheets or of the lid;

characterizing this packaging because one of the outer flaps or the cover, includes, along at least one of its lateral edges, at least one suitable fin to be folded perpendicularly to said flap, intended to be inserted into a slit in a position corresponding on the adjacent inner leaf, having the slit a longitudinal dimension smaller than the corresponding dimension of the fin, so that it can only be introduced after folding or deformation, to then recover its shape initial due to the elasticity of the semi-rigid material, remaining locked in this way under the inner flap, being arranged a cut in the wall adjacent to said flap, in front of at least a part of said fin, in order to distinguish it from the outside and check if it has been broken during a attempt to break the packaging.

To be more easily visible from the outside, the part of the fin face arranged in front of the Clipping may include a distinctive sign or be colored.

Advantageously, they can be provided respectively two fins along the two lateral sides of the same flap external and therefore two slits will be arranged in one corresponding position in the two internal flaps.

To be able to be introduced more easily in the associated clipping, the fin may include a protruding part laterally in front of the associated cutout and articulated by a highlighted on the rest of the fin. This fin can be separated easily from the outer flap, during a break attempt, and It therefore serves as an indicator of inviolability.

Other features and advantages of the invention they will appear in the following detailed description of one of their ways of implementation. In this description, it will be done reference to the attached drawings, in which:

Figure 1 is a view of the cardboard plate pre-cut and stressed corrugated from which the illustrated packaging;

Figure 2 is a perspective view of the assembled, partially open packaging;

Figure 3 is a perspective view of the assembled and closed packaging, as normally arrives at your addressee.

The box-type packing with flaps illustrated in the drawings it comprises two longitudinal walls 1 and 2, parallel each other and two transverse walls 3 and 4, perpendicular to the above, on which they are articulated by folding lines parallel. The four walls have the same height.

A band 5 articulated on the wall 2 by a folding line parallel to the previous ones is counter-bonded against the inside of the wall 3.

At the base of walls 1-4, They are articulated by folding lines perpendicular to the previous and arranged in the same plane, some background parts 6-9, here a well-known automatic fund, It is not necessary to describe in more detail. The bottom of packaging has no relation to the invention and can obviously be of any other type.

On top of walls 1 and 2 are articulated by parallel folding lines, some sheets, here essentially rectangular 10, 11, folded perpendicularly to the associated walls to form external flaps that overlap, while on top of walls 3 and 4 they are articulated by folding lines perpendicular to the above and located in the same plane as these, two sheets 12, 13, essentially rectangular here, folded perpendicular to the associated walls under the outer flaps 10, 11 to form Internal flaps

From two side edges of the flap external 10 laterally project two fins 14, 15, intended for be introduced respectively into two slits 16, 17, arranged in a corresponding position on the internal flaps 12, 13, in a position adjacent to the folding line by which you are flaps are articulated on the walls 3, 4, associated.

The grooves 16 and 17 have a length less than the corresponding dimension of fins 14 and 15, of way that once the packaging has been filled with the items conditioned, the legs can be introduced into the slits associated only after deformation or folding in said slits As depicted in the drawings, for facilitate its introduction, fins 14 and 15 comprise preferably a part that projects laterally, respectively, 14th and 15th, articulated on the rest of the fin by a folding line, in order to be able to be retracted during the introduction of the fin into the corresponding slit.

After inserting fins 14 and 15 into the grooves 16, 17, associated, projecting portions 14a, 15a, they recover their initial position due to the elasticity inherent in corrugated cardboard with which they are constituted. Obviously the same occurs if the fin is introduced into the slit due to deformation.

The fins 14, 15 are thus blocked. in position under the internal flaps 12, 13 with the flaps 10-11 external folded on top of the latter, and You can then lock the full packaging in closed position, by example applying on the two outer sheets 10, 11, along its continuous edges, a simple adhesive strip 18.

Cutouts 19 and 20 are arranged, respectively in walls 3 and 4, below the recesses 16 and 17, at a height such that they are in front of fins 14 and 15 and, more particularly, in the case represented, in front of the parts 14a and 15a, when the fins are introduced into the corresponding slits, which fins or parts of fins are of this mode visible from the outside.

If during the transport of the full packaging, produces a break attempt, by unraveling the band 18 and lifting of the flaps 10 and 11 to access the content of the packing, the displacement of the flap 10 has the effect of breaking fins 14 and 15, which fall to the bottom of the packaging and stop be visible from the outside through cuts 19 and 20.

The fold lines that connect the fins 14, 15 with the outer flap 10 may be provided with precuts to facilitate the breakage of the fins during a attempt to break up As a variant, such precuts may be provided on the fold line between fin parts 14a, 15a and fins 14, 15, thereby facilitating the breakdown of the fin parts 14a, 15a during a break attempt.

Even if the individuals who have opened the packaging replace the tape more or less carefully adhesive 18, the recipient of the package, upon receiving it, can, with a simple look through cuts 19 and 20, distinguish if the fins or parts of fins are apparent or not, and know so, without having to open the packaging, if it has undergone an attempt to breaking off. In this way it is possible, proceeding to verifications in each phase of transport, determine at what stage a packaging has could possibly be violated.

The face of the fin or part of the fin visible from the outside through cuts 19 and 20 will be preferably colored, to thus constitute an indicator of inviolability easy to distinguish.

It is clear that the packaging can comprise a only outer flap 10, which will cover the entire upper part of the packaging and serving as a cover, without leaving the frame of the invention.
