Problems solved by technology

However, precisely because of the absence of apparent modifications occurring during opening and closure, it is possible for these boxes to be tampered with, with the aim, for example, of replacing the contents of the box with an undesirable product.
This solution is, however, easy to get around in terms of unauthorized first opening, it being possible for the seal to be repositioned or replaced by someone tampering with malicious intent.
Furthermore, production and affixing of the seal increase the production price of the box.

first embodiment

[0053] illustrated in FIG. 3, the zone 10 of weakening extends in a curved line from a lateral border of the flap 9. The lateral borders of the flap 9 are defined as the borders extending from the edge 29 shared by the flap and a face.

[0054] According to the embodiment illustrated in FIG. 3, the curve of the zone 10 of weakening extends from one lateral border to the other of the flap 9 in a concave shape along the first surface 11. This concavity of the side of the first surface 11 gives this first surface 11 a greater surface area as compared to the second surface 12.

[0055] In such an embodiment, the curve of the zone 10 of weakening defines an arc of a circle of which the diameter is greater than or equal to the edge 29 shared by the flap 9 and a face. For example, the diameter of the arc of the circle of the curve 10 is between 100% and 150% of the length of the edge 29.

[0056] The curve of the zone 10 of weakening may also extend from a lateral border to the end border opposi...

second embodiment

[0058] illustrated in FIG. 4, the zone 10 of weakening extends in a straight line from a lateral border of the flap 9. The zone 10 of weakening is inclined at an angle α relative to the edge 29 shared by the flap and a face. The angle α must be sufficiently large to guarantee that a first surface 11 is larger than the second surface 12 of the flap, allowing folding of the flap 9 without altering the zone of weakening at the time of industrial packing, and sufficiently small to guarantee satisfactory tearing of the zone of weakening, the tab generating a force perpendicular to the lateral border of the flap when it is unfolded. An angle α of between from about 10° and about 80°, and preferably between from about 20° and about 60°, may fulfill such conditions in the example of a four-face box.

[0059] Other zones of weakening may be provided on the box according to the invention in order to enhance detection of first opening of the box.

[0060] According to one embodiment, the first fac...

Abstract

A polygonal box comprises faces (1, 2, 3), a lid (7) provided with a tab (8) suitable for arranging in a folded position against a first face (1) of the box, and a flap (9) that can be folded down around an edge (29) shared with a second face (2) of the box, the flap (9) having a zone (10) of mechanical weakening that is inclined relative to said edge (29).
The inclined zone (10) of weakening does not tear when the box is packed industrially and shows up first opening of the box by tearing-away of a surface (12) of the flap at the time of said first opening (FIG. 2).

Description

[0001] This application claims the benefit of priority of French Patent Application No. 03 / 12,708, filed Oct. 30, 2003, which is incorporated herein by reference in its entirety. BACKGROUND OF THE INVENTION [0002] 1. Field of the Invention [0003] The present invention relates to a polygonal box for use as packaging, for example for products to be consumed or for medicinal products. [0004] 2. Description of the Art [0005] A polygonal box of this invention includes faces, an apical surface and a base surface. Conventionally, the box may include four faces, possibly three or more than four, depending on the model. [0006] With reference to FIG. 1, a brief description will be given of a known box of this type having four faces 1, 2, 3, 4, the faces 3 and 4 not being clearly visible from the perspective of the figure. The apical 5 and basal 6 surfaces are generally similar and often differ only in terms of the printing on the box, which indicates the direction in which the product has bee...
