[0098] Note that in the present detailed description corresponding parts illustrated in the various figures are shown with the same numerical references. The figures may illustrate the subject matter of the invention by means of representations that are not to scale; therefore, parts and components illustrated in the figures related to the subject matter of the invention may relate only to schematic representations.

[0099] By the term product is meant an article or a compound of articles of any nature. The term product may also be used to mean packaging, for example, carrying a plurality of articles.

[0100] The term paper material means paper or paperboard, optionally having at least 50% by weight, preferably at least 70% by weight, of organic material comprising one or more of cellulose, hemicellulose, lignin, lignin derivatives. The paper sheet material that can be used to make the container can have a weight between 50 and 500 g / m2, optionally between 150 and 400 g / m2. The paper sheet material in question extends between a first and second prevalent development surface. The sheet paper material used to make the container may be covered for at least part of the first and / or second prevalent development surface by a plastic coating, such as a film, the object of which is to reinforce the paper material. The coating can also be used to define a kind of water and / or moisture barrier that is useful in preventing the weakening and loss of structure of the coupling system and container (optionally of the band or envelope) resulting in uncontrolled deformation of the paper material constituting the latter component. The coating may be applied to the paper material in the form of a so-said “coating” or lacquer laid down by solution or sprayed, the thickness of which is generally, but not limited to, between 0.2 and 10 μm. Alternatively, the coating may comprise a plastic film, such as a polycoating, applicable by a lamination process, on one or both sides of the paper material. Wherein the coating is applied by lamination, the values of the plastic film (coating) may, for example, vary between 5 and 400 μm, optionally between 10 and 200 μm, even more optionally between 10 and 100 μm, of coating material (i.e., polythene). The plastic coating material can be chosen, by way of example, from the following materials: PP, PE (HDPE, LDPE, MDPE, LLDPE), EVA, polyesters (including PET and PETg), PVdC.

[0101] The term “first closure condition” refers to a condition wherein the closure system is first arranged in occlusion of the storage passage opening to allow engagement between the first and second coupling portions. In the first closed condition, the first and second coupling portions define the locking condition of the container to occlude the passage opening of the storage. In the locking condition, the first and second coupling portions are intact (undamaged) and obstruct the passage of the container from the first closed condition to a first opening condition.

[0102] The term “first opening condition” means the passage of the container, for the first time, into the opening condition after it has been arranged (for the first time) in the first closed condition. In fact, the first opening condition is defined when for the first time the container is arranged in the opening condition after the first and second coupling portions have defined the locking condition.DETAILED DESCRIPTIONContainer

[0103] A tamper-evident container made of sheet material, e.g., paper material, for the containment and / or wrapping of products was collectively identified by 1.

[0104] The container 1 comprises a storage 2 made of sheet material, optionally paper material, extending in thickness between an outer surface and an inner surface, respectively delimiting at least part of an outer surface of the container and an internal volume 3 configured to house one or more products. The storage 2 comprises at least one lateral wall wrapped around itself and engaged at longitudinal sections. The lateral wall may be engaged by means of a glued portion, optionally by one or more glue points, such as hot glue or cold glue. Alternatively, the lateral wall may be glued by means of a glued portion defined by one or more layers of adhesive material, optionally adhesive material strips, or similar means of attachment.

[0105] The storage 2 defines a tubular body with a closed profile, which may have a substantially prismatic shape, such as having a polygonal, rectangular, trapezium shape or round base.

[0106] As shown in the accompanying figures, the storage 2 may comprise a front wall 4a and a back wall 4b facing and parallel to each other: the front wall 4a and the back wall 4b are connected to each other by a first and second connecting wall 4c, 4d, also facing and parallel to each other. The front wall 4a is spaced and opposed to the rear wall 4b; the first and second connecting walls 4c, 4d are also spaced and opposed to each other. The front and back walls 4a, 4b have an identical rectangular outline (walls identical in shape and size), similarly connecting walls 4c, 4d have an identical rectangular outline (walls identical in shape and size). Thus, the first and second connecting walls 4c, 4d, in the closed condition of the container, are interposed between the front wall 4a and the back wall 4b.

[0107] The front wall 4a and back wall 4b are joined in one piece to the first and second connecting walls 4c, 4d, which have a smaller surface area than a surface area of the front walls 4a and back walls 4b. In fact, the ratio between a surface area of front wall 4a or back wall 4b and the surface area of the first or second connecting wall 4c, 4d is comprised between 1.5 and 15.

[0108] The front, back and connecting walls (walls 4a, 4b, 4c, 4d) define two passage openings 5 opposed to each other and delimited, at opposing longitudinal ends, by a respective free edge 6. Each passage opening 5 defines a respective part of the container 1 suitable, in use, for the passage of products, i.e., for the withdrawal and / or insertion of products from / into the container 1. The storage 2 may comprise only one passage opening 5 and have at least one of lateral walls and a back wall, stably occluded and engaged with each other by glued portions.

[0109] Alternatively, the storage 2 can be substantially conformed as an envelope, that is, having the front wall 4a folded over the back wall 4b, to directly engage the same back wall 4b.

[0110] The front wall 4a may comprise a cutout defined at the free edge 6, which is configured to define a drop of the free edge 6 to facilitate the holding of a closure system 7 (described in the following) to allow the opening of the container 1. Optionally, the front wall 4a may comprise a cutout defined at each passage opening 5. The cutout may have a substantially “C”, “U”, or “V” shape.

[0111] As mentioned above, the container 1 further comprises at least one closure system 7 made of sheet material, optionally paper material, disposed at each passage opening 5 of the storage 2 and configured to occlude a respective passage opening to define a closed condition of the container 1. In particular, the closure system delimits, in cooperation with the storage, the internal volume 3 of the container. The closure system 7 is also movable with respect to the storage 2 at least between a closed condition of the container, wherein it prevents the passage of products from passage opening 5, and an open condition of the container, wherein it allows the passage of products from passage opening 5. In fact, the closure system 7 defines a lid of the container employed to manage, in use, the passage of products from passage opening 5.

[0112] The closure system 7 comprises a closure portion 9 engaged at the free edge 6 and movable, optionally by rotation, relative to the storage 2. As, for example, shown in FIG. 7, in the closed condition of the container, the closure portion 9 prevents communication between the internal volume 3 and the external environment, preventing the passage of products from the passage opening 5, while, in the open condition (see, for example, FIG. 10), the closure portion 9 allows communication between the internal volume 3 and the external environment, thus allowing the passage of products from the passage opening 5.

[0113] The closure portion 9 is made of sheet material, optionally paper material, extending in thickness between an inner surface, seamlessly connected with the inner surface of the storage 2, delimiting part of the internal volume 3 and an outer surface, seamlessly connected with the outer surface of the storage, delimiting part of an outer surface of the container. The closure portion 9 has a polygonal profile, for example having rectangular or square outline, fully countershaped to the free edge 6.

[0114] In the variant of the container 1 having two passage openings 5, the container 1 has two closure systems 7 comprising respective closure portions 9 engaged at free edges 6 of the storage 2 longitudinally opposed to each other. The closure systems 7 are therefore arranged in opposition to each other with respect to the storage 2 itself, in the form of a tubular body. Each closure system 7 can be joined in one piece to the storage 2 by a closure portion 9, joined in one piece to the free edge 6 and movable by rotation about it. Alternatively, the closure system 7 may be removably engageable to the storage 2. For example, the closure system 7 may have a plurality of lateral walls defining a compartment countershaped to the passage opening 5, configured to at least partially house the storage 2 and prevent the insertion and withdrawal of products from the storage.

[0115] The closure system 7 comprises an inserting portion 10 configured to be inserted at least partially, in the closed condition, into the internal volume 3, which is engaged to the closure portion 9 at a fold edge 9a opposed to the free edge 6. The inserting portion 10 extends from the closure portion 9 and, in the closed condition, is positioned in the internal volume 3 of the storage 2. The inserting portion 10 is also made of a flat sheet of paper material, extending in thickness between an inner surface seamlessly connected with the inner surface of the closure portion 9 facing, in the closed condition of the container, toward a central area of the internal volume, and an outer surface seamlessly connected with the outer surface of the closure portion 9 that, in the closed condition of the container, faces and at least partially contacts the front wall 4a of the storage 2.

[0116] The inserting portion 10 may be delimited by a perimeter border 10a defining a polygonal profile, e.g., rectangular, square, or having a trapezium shape.

[0117] The inserting portion 10 is seamlessly engaged to the closure portion 9 at a fold edge 9a opposite to the free edge 6 of the storage 2, around which the inserting portion 10 is movable by rotation. The inserting portion 10 can be constrained to a section of the free edge 6 defined by the back wall 4b by defining, in cooperation with the closure portion 9, a substantially “L-shaped” outline (see, for example, FIGS. 7-10, 24 and 27).

[0118] The container 1 may comprise at least one control opening 24 defined on the closure system 7 or the storage 2, to allow a user to verify the presence and / or engagement between a first and a second coupling portion 12, 13 of the container (these portions will be better described later), before a first open condition of the container (a condition subsequent to a first closed condition). The control opening 24 is at least partly delimited by a perimeter edge, which may have a closed profile, for example having a polygonal or circular conformation, or open profile.

[0119] If the control opening 24 is defined on the closure system 7 (see, for example, FIGS. 6 and 7), it may be entirely made on the inserting portion 10, extending from the fold edge 9a toward a central area of the inserting portion 10 to define a depth of said control opening 24. Alternatively, the control opening 24 may be entirely defined on the closure portion 9, extending from the fold edge 9a toward a central area of the closure portion 9 (toward the section of the free edge 6 delimited by the back wall 4b) to define a depth of said control opening 24.

[0120] If control opening 24 is defined on the storage (as shown in FIGS. 11 and 12), it may be present on the front wall 4a of the storage 2 and facing, in the closed condition, the first coupling portion 12.

[0121] As mentioned above, the container 1 comprises at least a first coupling portion 12 carried by the closure system 7, optionally by the inserting portion 10, and at least a second coupling portion 13 carried by the storage 2, which are configured to engage with each other during a first closed condition of the container (see for example FIGS. 7-9, 14-17). In the first closed condition, the first coupling portion 12 is entirely contained in the internal volume 3 of the storage 2 and is spaced from the free edge 6, allowing the engagement with the second coupling portion 13 placed entirely in the internal volume 3 of the storage 2.

[0122] The accompanying figures show two embodiments of the first coupling portion 12. In a first embodiment shown, for example, in FIGS. 7-9, 19, 22, the first coupling portion 12 comprises a panel consisting of a single sheet of paper material, joined in one piece to the inserting portion 10 at a lateral section of the perimeter edge 10a transverse to the fold edge 9a. The panel of the first coupling portion 12 has a surface area substantially equal to or lower than a surface area of the inserting portion 10; in fact, the ratio between the surface area of the inserting portion 10 and the surface area of the panel of the first coupling portion 12 is comprised between 1 and 5.

[0123] The panel of the first coupling portion 12 extends in thickness between an outer surface seamlessly connected with the outer surface of the inserting portion 10, and an inner surface seamlessly connected with the inner surface of the inserting portion 10, resulting in the panel of the first coupling portion 12 being folded and overlapping the inserting portion so that the respective inner surfaces of the panel of the first coupling portion 12 and the inserting portion 10 face each other. The inserting portion 10 is then arranged, in the closed condition of the container, in interposition between the front wall of the storage 2 and the gripping tab 12a. The inner surface of the panel of the first coupling portion 12 may be engaged to the inner surface of the inserting portion 10, and e.g., by means of an adhesive element such as a glue point or label, to define at least one constraining portion 12c having a surface area lower than a surface area of the inserting portion. In particular, the ratio between the surface area of the inserting portion 10 and the surface area of the constraining portion 12c is comprised between 1.3 and 5, optionally between 2 and 5. The constraining portion 12c may lie on a plane parallel to a plane of lying of the inserting portion 10 and have a polygonal shape, such as triangular, square or having a trapezium shape.

[0124] In the first embodiment, the first coupling portion 12 may also comprise at least one coupling portion 12a, adjacent and joined in one piece to a constraining portion 12c, which is suitable to cooperate with the second coupling portion 13 to determine a locking condition of the container. The gripping tab 12a has a polygonal outline, e.g., square, rectangular, or having a trapezium shape, and, like the constraining portion 12c, faces the inner surface of the inserting portion 10, resulting in at least partial spacing from the latter. In fact, the gripping tab 12a lies in a plane transverse to a plane of laying of the inserting portion 10. In other words, the gripping tab 12a of the first coupling portion 12 is inclined with respect to the plane of lying of the inserting portion, optionally with respect to the inner surface of the inserting portion, by an angle comprised between 1° and 20°, optionally comprised between 1° and 15°. The gripping tab 12a defines, in cooperation the inserting portion 10, a substantially “V” or “U” shape whose concavity, in the closed condition of the container, has an outgoing direction from the storage 2. The gripping tab 12a has a predetermined surface area that is lower than a predetermined surface area of the panel of the first coupling portion 12, but greater than the surface area of the constraining portion 12c; in fact, the ratio between the surface area of the gripping tab 12a and the surface area of the constraining portion 12c is comprised between 0.5 and 5.

[0125] The gripping tab 12a may have a gripping edge 12b spaced apart from the inserting portion 10 and consequently, spaced from the perimeter edge 10a of the same inserting portion, which is configured to abut against a respective undercut of the second coupling portion 13.

[0126] As shown in figures, the first coupling portion 12 according to the first embodiment may comprise a plurality of gripping tabs 12a, spaced from each other by a constraining portion 12c. The gripping tabs 12a of said plurality may be identical to each other and have the same shape and size. In particular, the first coupling portion 12 may comprise two coupling tabs 12a spaced apart from each other by the constraining portion 12c. Each gripping tab 12a may have a respective gripping edge 12b spaced from the inserting portion 10 and configured to engage distinct sections of the same undercut of the second coupling portion 13 or two distinct coupling portions.

[0127] The first coupling portion 12 according to the first embodiment may comprise at least one notch 46 defined on the panel of the first coupling portion 12, interposed between the constraining portion 12c and the gripping tab 12a, which effectively separates the constraining portion 12c and the gripping tab 12a. The notch 46 may be notch 46 passing through the panel of the first coupling portion 12, extending in length transversely, optionally orthogonally, to the gripping edge 12b of the gripping tab 12a of the first coupling portion 12. Note also how notch 46, at one longitudinal end, is spaced apart from the gripping edge 12b of the panel of the first coupling portion 12, such that the gripping tab 12a is spaced apart from a surface of the inserting portion 10.

[0128] A variation of the first coupling portion 12 according to the first embodiment is shown in FIG. 22; this first coupling portion 12 comprises:

[0129] a first constraining portion 12c′ engaged, optionally by gluing, to an inner surface of inserting portion 10,

[0130] a first gripping tab 12a′ joined in one piece and flanked to the first constraining portion 12c′,

[0131] a second constraining portion 12c″ spaced apart from the first constraining portion 12c″,

[0132] a second gripping tab 12a″ joined in one piece and flanked to the second constraining portion 12c′, resulting spaced from both the first constraining portion 12c′ and the first gripping tab 12a′.

[0133] Thus, the first constraining portion 12c′ is interposed between the first gripping portion 12a′ and the second constraining portion 12c″, while the second constraining portion 12c″ is interposed between the first constraining portion 12c′ and the second grip tab 12a″. The panel of the first coupling portion 12 may also have a notch 46 interposed between the first constraining portion 12c′ and the first gripping tab 12a′, to allow the same first gripping tab 12a′ to be spaced from the inserting portion 10. In other words, the first and second constraining portions 12c′, 12c″ are engaged at a central or inner zone of the inserting portion 10, while the first and second gripping tabs 12a′, 12a″ are arranged at an outer zone of the inserting portion 10 with respect to the first and second constraining portions 12c′, 12c″, resulting in opposition to each other. In such a variant, the closure system 7 may have a through opening defined on part of the inserting portion and the panel of the second coupling portion 12, which distances the first and second constraining portions 12c′, 12c″.

[0134] In a further variant of the first coupling portion 12 according to the first embodiment, the first coupling portion 12 may comprise at least one spacer 12d engaged to the panel of the first coupling portion 12. The spacer 12d may be defined by an additional tab joined in one piece to the tab 12a of the second coupling portion 12, folded with respect to the latter such that it faces the inner surface of the panel of the second coupling portion 12. The spacer 12d is at least partially countershaped and overlapped with the tab 12a, resulting in interposed between the same tab 12a and the inserting portion 10. The spacer 12d can also be glued to the tab 12a, increasing its thickness.

[0135] The first coupling portion 12 according to the first embodiment may further comprise a support tab 12f (FIGS. 16 and 17) joined in one piece to the constraining portion 12c of the second coupling portion 12 and facing the outer surface of the panel itself. In the closed condition of the container, the support tab 12f is facing the second coupling portion 13 so that the latter is interposed between the support tab 12f and the panel of the second coupling portion 12. In this way, if a user attempts to tamper with the container by moving the coupling portion 9 toward the internal volume of the storage 2, the support tab 12f forces the weakening 14 (described below) e.g. defined on the second coupling portion 13, to break. In other words, the support tab 12f prevents the insertion of the closure portion 9 of the closure system 7 without breaking the weakening 14.

[0136] In fact, in the first embodiment described above, the first coupling portion 12 is defined by a panel superimposed on the inserting portion that defines the engagement portion suitable for constraining, in the first closed condition of the container, to the second coupling portion 13.

[0137] In the second embodiment shown in FIGS. 24, 25, 27 and 28, the first coupling portion 12 emerges from the closure system 7: the first coupling portion 12 protrudes from the inserting portion 10, optionally from an opposite side to the inserting portion 9 and without overlapping with said inserting portion 10. In such a configuration, the inserting portion 10 is interposed between the first coupling portion 12 and the closure portion 9. In other words, the first coupling portion 12 according to the second embodiment, extends seamlessly from the inserting portion 10 and lies on a plane substantially parallel to the plane of laying of the inserting portion 10: the first coupling portion 12 lies on of plane coincident with a plane of laying of the inserting portion 10.

[0138] Also in the second embodiment, the first coupling portion 12 has a tab 12a. In that embodiment, the tab 12a comprises at least one hook 120 configured to define the engagement portion of the first coupling portion 12 configured to engage to the second coupling portion 13, in the first closed condition of the container. The at least one hook is delimited by a gripping edge 120′ which may have a substantially “C” shape. The concavity defined by the “C” shape of the hook 120, in the closed condition of the container, faces at least one of the first and second connecting walls 4c, 4c of the storage 2. The at least one hook 120 of the tab 12a may comprise at least one first and one second hook, each of which is delimited by a respective gripping edge 120′ having opposing concavities. In detail, each of said first and second hooks of the first coupling portion has a substantially “C” shaped outline. The concavity defined by the “C” shaped outline of the first hook is facing opposite to the second hook, while the concavity defined by the “C” shaped outline of the second hook is facing opposite to the first hook.

[0139] In still greater detail, the tab 12a comprises a central body 125 that supports the at least one hook 120 which is laterally engaged to the central body. In detail, as shown in FIGS. 24 and 27, the central body 125 is interposed between said first and second hooks of the first coupling portion 12a.

[0140] The tab 12a of the first coupling portion 12 comprises an inserting portion 127 spaced apart from the inserting portion 10: optionally, the inserting portion 127 is placed, with respect to a central portion of the tab 12a, in opposition to the inserting portion 10. The insertion portion 127 of the tab, during the transition from an open condition to the first closed condition of the container, is configured to contact the second coupling portion 13 and guide the insertion of the first coupling portion 12 in engagement to the second coupling portion 13. In detail, the insertion portion 127 is defined on the central body 125 of the tab 12a and is delimited, optionally on the opposite side from the insertion portion 10, by a perimeter edge 127′ having a substantially conical shape; the conical shape of the perimeter edge 127′has a tapered conformation facing the insertion portion 10.

[0141] The second coupling portion 13 comprises a locking tab 13a coplanar to a plane of lying of the front wall 4a of the storage 2 and configured to delimit, in cooperation with the lateral walls, the interior volume 3 of the storage. As shown in the accompanying figures, the container comprises a through notch 13c which can be defined directly on the lateral wall of the storage bearing the second coupling portion 13 and configured to inferiorly delimit the locking tab 13a which is then interposed between a section of the free edge 6 and the through notch 13c. The through notch 13c can extend across an entire width of the front wall 4a, from the first connecting wall 4c to the second connecting wall 4d (see, for example, FIG. 2), along a direction parallel to the section of the free edge defined by the front wall 4a. Alternatively, the through notch 13c may develop for a preponderant part of the width of the front wall 4a, resulting in spacing from the first and second connecting walls 4c, 4d (see for example FIG. 4). The ratio between the width of front wall 4a and the length of through notch 13c may be comprised between 0.2 and 1.

[0142] The through notch 13c also defines:

[0143] a gripping edge 13b of the locking tab 13a, which may be parallel and spaced from the free edge 6 of the storage and configured to engage the first coupling portion 12,

[0144] a passageway designed to receive in crossing the inserting portion 10 and the first coupling portion 12 to allow it to be engaged with the second coupling portion 13.

[0145] The locking tab 13a can have a predetermined height defined by the minimum distance between gripping edge 13b and the free edge 6 of the storage 2, greater than 2 mm, optionally comprised between 3 mm and 30 mm, even more optionally comprised between 3 mm and 20 mm.

[0146] In the accompanying figures, the through notch 13c is defined, in a non-limitingly way, on the front wall 4a. The through notch 13c may comprise a single section spaced from the free edge 6; the single section of through notch 13c may be at least partially parallel to a section of the free edge 6 of the storage 2. Additionally, the through notch 13c may be delimited by a perimeter edge having a closed profile to define, in a condition wherein the locking tab 13a lies on a plane parallel to the lateral wall of the storage directly bearing the second coupling portion 13, a through-access 40 delimited by a perimeter edge having closed-profile (see, for example, FIG. 25). The through notch 13c delimits the gripping edge 13b, spaced from the free edge 6 of the storage 2: the gripping edge 13b is offset from the free edge 6 of the storage 2, optionally from a central portion of the locking tab 13a. At least one section of the gripping edge 13b defines the perimeter edge of the through access 40.

[0147] The locking tab 13a essentially defines a hook 130 configured to be engaged to the tab 12a of the first coupling portion 12, optionally to the at least one hook 120 of the tab 12a of the first coupling portion 12. The gripping edge 13b has a substantially “C” shaped profile; in detail, the gripping edge 13b has a central section 13b′ and two opposing end sections 13b″ (FIG. 25): the central section 13b′ can be substantially straight, optionally parallel to the section of the free edge 6 defined by the lateral wall directly bearing the second coupling portion 13 (e.g., front wall 4a). Instead, the end sections 13b′ can be slanted with respect to the central section 13b′, optionally slanted with respect to the section of the free edge 6 of the storage 2 defined by the lateral wall of the storage 2 directly bearing the second coupling portion 13. In detail, the through notch 13c may have:

[0148] a central through notch suitable for defining the through access 40,

[0149] a first and second lateral through notch opposed and spaced apart from each other with respect to the central through notch.

[0150] The first and second lateral notches can be joined to the free edge 6 of the storage 2 to delimit, together with the central through notch, the locking tab hook 13a of the second coupling portion 13.

[0151] Further embodiments of the second coupling portion 13 are shown, for example, in FIGS. 2-5, which have respective differentiating structural features compared to the second coupling portion 13 previously described, but which equally allow engagement with the first coupling portion 12 previously described. In particular, the variant of the second coupling portion 13 shown in FIG. 2 has a locking tab 13a made by means of an upper notch and a lower notch defined on the front wall 4a along sections parallel to each other and spaced from the free edge of the storage 2. The upper notch and the lower notch 13c′, 13c″ may have the same length extending fir an entire transverse footprint of the front wall 4a or may have a reduced length, resulting spaced from fold edges of the front wall 4a with the first and second connecting walls 4c, 4d, respectively.

[0152] The lower notch 13c″ defines a passageway suitable for receiving in crossing the inserting portion 10 and the first coupling portion 12 to allow the latter to be engaged with the locking tab 13a of the second coupling portion 13. The locking tab 13a is then spaced from the free edge by a distance greater than 2 mm, optionally comprised between 3 mm and 15 mm. Note that this distance essentially coincides with the distance of the upper notch 13c′ from the free edge 6, while the lower notch 13c″ is spaced from the free edge 6 by a distance greater than 4 mm, optionally comprised between 6 mm and 45 mm.

[0153] The second coupling portion 13 may have a protrusion that defines a projection that, in the first closed condition of the container, protrudes from the container to be felt by touch. In the first closed condition of the container, the control opening 24 is configured to allow the protrusion to pass through and thus escape from the storage 2. The protrusion provides to the user a tactile information and not exclusively visual, allowing even blind users to verify the integrity of the container.

[0154] Alternatively, the through notch 13c may comprise two end sections 13e defined on the locking tab 13a that develop transversely, optionally orthogonally, to the free edge 6 (FIG. 3). Each end section 13e is spaced from the free edge 6, having a height measured along a direction orthogonal to the free edge that is lower than the height of the locking tab 13a. The end sections 13e are opposed to each other with respect to the centerline plane, defining weakening points to facilitate the breaking / separation of the locking tab 13a subsequent to the first open condition of the container.

[0155] A further variant of the second coupling portion 13, the through notch 13c extends between two ends respectively coincident with the end sections 13e. In such an embodiment, the through notch 13c is spaced by fold edges of the front wall 4a with the first and second connecting walls 4c, 4d, respectively. The control opening 24 can be made at side areas of the inserting portion 10 and the panel of the second coupling portion 12, resulting, in the first closed condition of the container, facing respective end sections 13e of the locking tab 13a. As a further variant, the second coupling portion 13 may have a locking tab 13a defined by a through notch 13c having two distinct and aligned sections along a same direction parallel to the section of the free edge defined by the front wall 4a. Note that the minimum distance between the two adjacent ends of the two sections of the through notch is lower than a minimum distance between the two notches 46 respectively delimiting the first constraining portion 12c′ with the first gripping tab 12a′ and the second constraining portion 12c″ with the second gripping tab 12a″, thus allowing the first and second gripping tabs 12a′ and 12a″ to be inserted into a respective notch.

[0156] A further variant of the second coupling portion 13 not shown in the accompanying figures comprises a through notch 13c having two pairs of parallel sections, opposed to a centerline plane of the front wall 4a orthogonal to a section of the free edge 6 defined by the same front wall 4a. In such embodiment, the sections of each pair of sections extend along straight directions parallel to each other.

[0157] The locking tab 13a may have a height measured along a direction orthogonal to the section of the free edge defined by front wall 4a, ranging from 30 mm to 60 mm, optionally comprised between 30 mm to 55 mm.

[0158] A further variant of the second coupling portion, the panel of the second coupling portion 13 separating the locking tab 13a from the free edge 6 has a through opening that allows the first coupling portion 12 to engage within the second coupling portion itself. The second coupling portion 13 may also have two or more through openings defined on the panel of the second coupling portion 13 that are distinct and spaced apart from each other.

[0159] As shown in the accompanying figures, the locking tab 13a may have oblique weakenings 14, which are interposed between the through notch 13c and the free edge 6 and inclined with respect to the through notch 13c by an angle comprised between 5° and 50°, optionally comprised between 8° and 45°. Also note that the weakenings 14 develop for the entire height of locking tab 13a and are symmetrical with respect to a centerline plane of the front wall 4a orthogonal to the section of the free edge 6 defined by the front wall 4a. The control opening 24 may be made at lateral areas of the inserting portion 10 that, in the first closed condition of the container, face a respective weakening 14.

[0160] In a further variant, the through notch 13c may have:

[0161] at least one upper section 20a spaced from the free edge 6 of the storage 2,

[0162] at least one lowered section 20b joined to the upper section and extending away from the free edge of the storage 2.

[0163] The through notch 13c may also have two opposing upper sections 20a, in interposition of which is the lowered section 20b that joins together the upper sections 20a. The upper sections 20a may develop along respective straight directions, orthogonal to the free edge 6 of the storage 2 and symmetrical to a container centerline plane orthogonal to the section of the free edge 6 defined by the front wall 4a. In contrast, the lowered section 20b has a convex conformation, e.g., having a “C” or “U” shape, with concavity facing the free edge of the storage 2. The locking tab 13a can be countershaped to the through notch 13c and delimited, on the side opposite the free edge 6, by:

[0164] at least one gripping section coincident with the upper section 20a of the through notch 13c, which defines at least part of the gripping edge 13b configured to engage, in the first closed condition, the gripping tab 12a of the first coupling portion 12,

[0165] a lowered section coincident with the lowered section 20b of the through notch 13c, which is joined to the gripping section and extends away from the latter.

[0166] Since the gripping section defining the gripping edge 13b is coincident with each upper section 20a of the through notch 13c, the locking tab 13a may have two or more gripping edges 13b countershaped to a respective upper section 20a, each configured to engage a respective gripping tab 12a of the first coupling portion 12. Note that only the gripping edge 13b of the locking tab 13a defined by the gripping section is configured to engage the first coupling portion 12 in the first closed condition of the container, while the lowered section is, in the closed condition of the container, spaced away from the gripping edge 13b.

[0167] As previously mentioned, the locking tab 13a can be countershaped to the through notch 13c and directly constrained to the storage at least through a first and second attachment portions 22a, 22b defining a weakening 14 configured to break during the first open condition of the container. In particular, the locking tab 13a is constrained to a section of the free edge 6 of the storage by the first attachment portion 22a and is constrained to the front wall 4a of the storage 2 by the second attachment portion 22b.

[0168] Turning now to describe the engagement between first and second coupling portions 12, 13, the inserting portion 10 is partially inserted into the passage defined by the through notch 13c, in interposition between the front wall 4a of the storage and the locking tab 13a. Note that the inserting portion 10 is only partially overlapping the locking tab 13a, leaving one surface of the locking tab 13a exposed. In other words, the inserting portion 10 is spaced from the second inserting portion 22b, wherein at least a portion of the lowered section 20b, together with the inserting portion 10 define, in the first closed condition of the container, a control opening 23 (FIG. 21) configured for displaying from outside the container, part of the lower portion of the locking tab joined to the lateral wall of the storage by means of said second inserting portion 22b.

[0169] The control opening 23 may be spaced away from the free edge 6 to allow, following the first open condition of the container, the display from the outside the container, the internal volume of the storage, or the damage or breakage of the weakening 14. If the container has not been subject to a tampering attempt, the control opening 23 allows the locking tab 13a to be displayed, allowing a user to verify the integrity of the container. To facilitate the user to verify the presence of the locking tab 13a, the area of the same locking tab 13a defined at the control opening 23 may have a different color from a color of the storage 2 or the inserting portion 10.

[0170] If the container has been subjected to a tampering attempt resulting in the breaking of the locking tab 13a, the control opening 23 allows to verify the separation of the locking tab 13a from the storage 2, giving evidence of tampering.

[0171] In a further variant, the second coupling portion 13 comprises a base body 35 engaged to a lateral wall of the storage 2 internally to the interior volume 3 (see, for example, FIGS. 14 and 15). In such a configuration, the second coupling portion 13 can be directly engaged to the storage 2, for example, by means of a glued portion, or it can be joined in one piece to a section of the free edge 6 and folded with respect to the latter in the internal volume 3 of the storage. Note that the base body 35 of the second coupling portion 13 is engaged to the front wall 4a of the storage, resulting in facing the first coupling portion 12 at least after the first closed condition of the container. The second coupling portion 13 may have a locking tab 13a that engages, in the closed condition of the container, the first coupling portion 12, defining the locking condition. In contrast to what has been previously described, the locking tab 13a extends in a plane of lying parallel to a plane of lying of the front wall 4a of the storage 2; the locking tab 13a is therefore facing the inner surface of the storage 2. The locking tab 13a is defined by at least one through notch 13c made on the base body 35 of the second coupling portion 13, which allows the inserting portion 10 and the first coupling portion 12 to be received in passage for engaging the second coupling portion 13. The through notch 13c also defines a gripping edge 13b that inferiorly delimits the locking tab 13a and is configured to engage with the first coupling portion 12. The locking tab 13a has a height defined by the minimum distance between the gripping edge 13b and the free edge 6, greater than 2 mm, optionally comprised between 3 mm and 30 mm.

[0172] The container may further comprise at least one support element 19 located in the internal volume 3 of the storage 2 and configured to contact the locking tab 13a at least during the transition of the container from the open condition to the first locking condition. In fact, the support element 19 prevents the hook 130 of the locking tab 13a from bending excessively with respect to the lateral wall of the storage directly bearing the second coupling portion or even from completely tipping over, thereby preventing the engagement with the first coupling portion 12. In other words, the support element 19 is configured to allow correct relative movement of the hook 130 of the locking tab 13a relative to the storage such that engagement with the first coupling portion 12 is ensured.

[0173] In a first embodiment, the support element 19 is engaged directly to the locking tab 13a (optionally to the hook), on the side opposite to the gripping edge 13b, e.g., by the weakening (see e.g., FIG. 19). The support element 19 is folded with respect to said hook 130 in the internal volume of the storage 2 and constrained, e.g., by glue, to the inner surface of the storage at an area of the same support element 19 opposite to the aforementioned section of the free edge 6. Note that the panel of the first coupling portion 12, in the closed condition of the container, is interposed between the inserting portion 10 and the support element 19, which supports the locking tab 13a both during insertion of the panel of the first coupling portion 12 and during extraction of the latter, keeping the first coupling portion 12 engaged to the second coupling portion 13. In other words, the support element 19, preventing the movement of the panel of the first coupling portion 12, prevents attempts to tamper the container involving tool insertion through the control openings 24.

[0174] Following the first open condition of the container, the weakening of the support element 19 is configured to break at the weakened section coincident with the free edge 6, allowing the separation of the locking tab 13a from the storage.

[0175] FIG. 28 shows a variant of the support element 19 which is solely constrained, optionally by glue, to the lateral wall of the storage 2 directly bearing the second coupling portion 13. Such support element 19 is spaced from the free edge 6 of the storage 2 and faces the through notch 13c. In detail, said support element 19 extends between:

[0176] a base portion 19′ constrained to the lateral wall of the storage directly carrying the second coupling portion 13, and

[0177] a top portion 19″ facing the through notch 13c.

[0178] In an aspect according to the preceding aspect, the top portion 19″ of the support element 19 is configured to contact a central portion of the hook 120 defined by the tab 12a of the first coupling portion 12: the top portion 19″ of the support element 19 is spaced from the free edge 6 of the storage 2. In fact, the hook 130 of the locking tab 13a of the second coupling portion 13 extends in height between the gripping edge 13b and an opposing top edge (an edge substantially aligned with the free edge of the storage of the lateral wall directly supporting said second coupling portion 13). The top portion 19″ of support element 19 is spaced from the top edge of the hook 130 of the locking tab 13a: the top portion 19″ of the support element 19 is substantially interposed between the base portion 19″ and the top portion 19″ of the support element 19.

[0179] The support element 19 may further comprise a protrusion 19c having an arcuate shape that emerges from the top portion 19″; said protrusion 19c is facing the hook 130 of the second coupling portion, substantially located at a distance from the through notch 13c (optionally above the through access 40). This protrusion 19c allows to intercept the first coupling portion 12, during the first inserting condition of the latter in the storage, preventing the tab 12a from abutting against the edge of the second coupling portion delimiting the through access 40. In fact, the support element 19 acts as a guide for the tab 12a of the first coupling portion 12 for the proper engagement of the latter with the panel 13a of the second coupling portion 13.

[0180] As seen for example from FIG. 28, the support element 19 may comprise one or more notches 19d configured to allow relative movement of the top portion 19″ relative to the base portion 19″, optionally to properly support the panel 13a of the second coupling portion. Each notch 19d may be a through notch and have a length comprised between 1 mm and 15 mm. As mentioned above, the panel 13a of the second coupling portion 13 can be joined to the storage by at least the weakening 14; the through notch 19d on the support element (19) can then be defined close to the weakening 14, optionally facing the weakening portion of the second coupling portion. The length of the notch 19d may vary depending, for example, on the height of the hook 130 of the second coupling portion 13 and / or depending on the movement allowed to the panel 13a during engagement with the first coupling portion 12.

[0181] The container may further comprise one or more lateral tabs 8, each engaged to a respective one of the first and second connecting walls 4c, 4d by a weakening. Each lateral tab 8, at least in the first closed condition of the container, is folded into the compartment of the container and facing the closure portion 9. The coupling portions 8 may define respective second coupling portions 13 that when folded into the internal volume 3 and in contact with a respective gripping tab 12a of the first coupling portion 12, define the locking condition of the container. In such an embodiment, the removable portion is defined by each of the lateral tabs 8, which are configured to break and separate from the storage after the first open condition of the container to give a user evidence of tampering. In fact, the lateral tabs 8 are engaged to a respective lateral connecting wall 4c, 4d of the storage 2 by the weakening 14 to allow each lateral tab to separate from the container during the first open condition.

[0182] At least one among the closure system 7, the storage 2, the first coupling portion 12, and the second coupling portion 13 comprises a weakening 14 configured to allow, following a first open condition of the container 1, the brake and / or separation of at least one of said first and second coupling portions 12, 13 to give evidence of tampering with the container 1. For example, the weakening 14 may be defined on the second coupling portion 13. In an embodiment of the container, the weakening 14 is defined at a central area of the inserting portion 10 that separates the perimeter edge section 10a joined in one piece to the panel of the second coupling portion 12, with the section of the perimeter edge 9a joined in one piece to the closure portion 9 of the closure system 7. The weakening 14 may develop along a straight direction connecting two side sections of the perimeter edge 10a of inserting portion 10, or the weakening 14 may have a curvilinear conformation surrounding the section of the perimeter edge 10a joining the panel of the second coupling portion 12 with the inserting portion 10. The weakening 14 may then develop along a trajectory having an open profile conformed as a “U”, “V”, or “L” shape. The removable portion may then be defined by part of the inserting portion 10 joined in one piece to the panel of the second coupling portion 12, which is separable from the remaining part of inserting portion 10 joined in one piece to the closure portion 9 of the closure system 7, allowing evidence of a tampering attempt to be given after the first open condition of the container.

[0183] In a further variant of the container, the weakening 14 may be on the closure portion 9. The removable portion is then defined by the panel of the second coupling portion 12, the inserting portion 10, and part of the closure portion 9 connected to the inserting portion 10, such that after the first open condition of the container, the weakening 14 allows its separation. In such a configuration, only part of the closure portion 9 hinged to the free edge 6 is integral to the storage. In a further variant, the weakening 14 may be entirely defined on closure portion 9 and extend along a trajectory having a closed profile conformed as a circular or polygonal shape, e.g., square, rectangular, or having a trapezium shape. The weakening 14 thus allows the closure portion 9 to be broken and consequently to give evidence to a user of a tampering attempt involving the movement of the closure wall 9 into the internal volume 3 of the container. The weakening 14 is then configured to break as a result of the application of a force on the closure portion 9 directed toward the internal volume 3 of the storage, thus giving evidence of an attempt to tamper with the container. The weakening 14 can further be defined on the second coupling portion and / or the storage 2 such that the locking tab 13a can be broken and / or separated during the transition of the container from the first closed condition to the first open condition. The second coupling portion 13 may then have the removable coupling portion at least partially defined by the locking tab 13a and configured to break and / or separate from the container after the first open condition of the container to give evidence of a tampering attempt.

[0184] For example, the second coupling portion 13 may comprise at least one weakening 14 defined by a cut on the locking tab 13a transverse to a section of the free edge 6 and extending for the entire height of the locking tab 13a, i.e., from the through notch 13c to at the free edge 6. The weakening 14 may be made in a central area of locking tab 13a, aligned with a centerline plane of the lateral wall 4 of the container carrying the second coupling portion 13 to allow the breaking of the locking tab 13a into two panels of equal size. However, it is possible to provide a lateral weakening, close to a respective fold edge between the front wall 4a and one of the first and second connecting walls 4c, 4d.

[0185] After the first open condition of the container and the consequent breaking or separation of the locking tab 13a of the second coupling portion 13, a user determines that the container has been tampered, for example, if it is returned to the closed condition, by verifying the absence of the locking tab through the control opening 24, which will directly show the internal volume 3 of the storage 2. Thus, note that the control opening 24 may, for example, be made on the inserting portion 10, resulting, in the first closed condition of the container, facing the tab 13a of the second coupling portion 13, allowing its presence to be verified if the container is intact, or its absence if the container has already been opened a first time.

[0186] As another alternative, the weakening may be present at the hook 130, specifically to connect the locking tab 130 to the storage 2. In such a configuration, the entire hook 130 of the second coupling portion 13 defines the removable portion of the container configured to be removed during the transition of the container from the first closed condition to the first open condition.Process for Making the Container 1

[0187] It is also an object of the present invention to provide a process for making a container 1 according to one or more of the above claims and / or description.

[0188] The process involves arranging the storage 2 which, as described above, is made of sheet material, optionally paper material. This step involves arranging at least a first sheet 51 comprising at least a first and a second portion 52, 54 interconnected by a central connecting portion 53. The first sheet 51 further comprises at least one first and one second lateral linking portion 55, 56. The central connecting portion 53 is interposed between the first and second portions 52, 54, the first portion 52 is interposed between the first lateral linking portion 56 and the central connecting portion 53, and the second portion 54 is interposed between the second lateral linking portion 55 and the central connecting portion 53. The first and second portions 52, 54 have substantially the same shape and size, while the lateral linking portions 55, 56 also have substantially the same rectangular profile. Each of said portions 52, 53, 54, 55, 56 comprises at least two opposing longitudinal edges and two opposing end edges: the portions 52, 54, the central connecting portion 53 and said lateral linking portions 55, 56 are joined along longitudinal edges and aligned along a single connecting direction.

[0189] The step of arranging the storage 2 involves a step of folding the first sheet 51 at the side edges of the portions 52, 53, 54, 55, and 56 in such a way as to join together the lateral linking portions 55, 56. The first sheet is wrapped around itself so as to bring the lateral linking portions 55 and 56 into contact (overlap). To maintain the storage 2 in the folded three-dimensional form, the process may involve, in a non-limiting manner, the application of a predetermined amount of glue, such as a cold glue, to at least one of the lateral linking portions 55, 56 that are suitable for resting on each other: joining said portions allows the storage 2 to be locked in the folded configuration. In the accompanying figures, a process involving the application of a predetermined amount of glue only on a lateral linking portion has been illustrated in a non-limiting way. The possibility of applying glue to both portions 55 and 56 is not excluded.

[0190] The process also involves arranging the closure system 7. This step involves arranging at least a second sheet 57, joined in one piece to the first sheet 51 at an end edge of the first and / or second portions 52, 54 of the first sheet 51. The second sheet 57 comprises at least one first and second portions 58, 59 joined together in one piece: the first portion 58 of the second sheet 57 is connected to the first sheet 51 such that said first portion 58 is interposed between the second portion 59 of the second sheet 57 and the first sheet 51. A preferred, but not limiting configuration of the invention is illustrated in the accompanying figures, wherein two second sheets 57 are engaged to the first sheet 51 and arranged in opposition to the first sheet 51. Each second sheet 57 is, for example, connected to a respective end edge of the first and / or second portions 52, 54 of the first sheet 51.

[0191] The process also includes folding steps of the first and second portions 58, 59 of the second sheet 57 to respectively form the closure portion 9 and the inserting portion 10 of the closure system 7. The folding step of the second sheet is preferably performed in a non-limiting way, following the engagement of the portions 55 and 56 of the first sheet 51.

[0192] The step of arranging the closure system 7 may also include a sub-step of arranging at least one portion 61 connected to at least one central and / or lateral connecting portion of the first sheet 51 and emerging from the latter on the same side from which the second sheet 57 emerges.

[0193] The process may further include a step of forming, on each second sheet 57, at least one through notch 69 defined at least on the second portion 59 of the second sheet 57, optionally in interposition between the first and second portions 58, 59 of the second sheet 57, configured to define the control opening 24. The notch 69 is executed substantially at a connecting edge between the first and second portions 58, 59 of the second sheet 57.
