Description

TITLE: ?CONTAINER WITH EVIDENCE OF TAMPERING AND PROCEDURE FOR ITS CREATION?

DESCRIPTION

FIELD OF FOUND

The present invention concerns a tamper-evident container and a process for its production. The container can be used in sectors involving the packaging of products and in which security is required that allows evidence of any tampering with the packaging. For example, the container can be used in the sectors of packaging, communication (for example for postal services), food, transport and logistics.

BACKGROUND OF THE FINDING

Tamper evident containers made of paper sheet material are known in the packaging industry. A first example described in patent application No. EP2239203A1 shows a tamper evident container comprising a magazine that can be closed by means of a closing system. The container comprises two tabs emerging laterally from the closing system which, during a closed condition of the container, are configured to be folded by the user and inserted into the magazine, in engagement with a folded tab. The lateral tabs carried by the closing system are configured to break during a first opening condition of the container.

A second example described in patent application No. US2008308619A1 shows a tamper evident container comprising a magazine closable by a closure system. The container includes a tab emerging from the closure system which, during a closed condition of the container, is configured to be folded by the user over an external surface of the closure system and inserted into the magazine, in engagement with a folded tab. The tab carried by the closure system is configured to break during a first open condition of the container.

The Applicant noted that the containers described in the first and second examples are easily tampered with and are also incapable of providing evidence of tampering.

A third example described in patent application No. WO 2015/170203 A1 shows a tamper-evident container having a magazine that can be closed by means of a locking system. The container comprises a first hook portion defined on the locking system and a second hook portion arranged in the magazine: the first and second hook portions are configured to engage during a first closing condition of the container. The second hook portion defines a removable portion configured to separate from the container during a first opening condition of said container, subsequent to the first closing condition. The magazine has a through opening that allows viewing of the removable portion.

A fourth example described in patent application No. EP3461756A1 shows a tamper evident container similar to the container in patent application No. WO 2015/170203 A1. Unlike the container in the third example, the second removable attachment portion described in patent application No. EP3461756A1 is hinged directly onto an external side wall of the magazine.

Although the known containers described above are currently used to define tamper-evident solutions, the Applicant has noted that these can be improved in several respects.

PURPOSE OF THE FINDING

The aim of the present invention is therefore to substantially resolve at least one of the drawbacks and/or limitations of the previous solutions.

A first objective of the invention is to provide a container with a simple structure, easily realizable using existing systems, and at the same time capable of effectively providing evidence of a tampering attempt; in particular, the aim of the invention is to provide a tamper-evident container realizable at low cost, which does not require modification of existing systems used for the production of standard containers.

DEFINITIONS AND AGREEMENTS

Please note that in this detailed description corresponding parts illustrated in the various figures are indicated with the same numerical references. The figures may illustrate the subject matter of the invention by means of representations not to scale; therefore, parts and components illustrated in the figures relating to the subject matter of the invention may concern exclusively schematic representations.

The term product means an article or a composite of articles of any nature. The term product can also be understood as a package, for example carrying a plurality of articles.

The term paper material means paper or cardboard, optionally containing 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 used to make the container can have a weight of between 50 and 500 g/m?, optionally between 200 and 400 g/m?. The paper material in question extends between a first and a second prevalent development surface. The paper sheet material used to make the container can be covered for at least part of the first and/or second prevalent development surface by a plastic coating, for example a film, the purpose of which is to reinforce the paper material. The coating can also be used to define a sort of barrier to water and/or humidity. useful to avoid the weakening and loss of structural integrity of the attachment system and the container (optionally the band or bag) with consequent uncontrolled deformation of the paper material constituting the latter component. The coating can be applied to the paper material in the form of a so-called ?coating? or lacquer deposited from solution or sprayed whose thickness is generally between 0.2 and 10 ?m. Alternatively, the coating may comprise a plastic film, for example a polythene, applicable by means of a lamination process, on one or both sides of the paper material. In the case in which the coating is applied by lamination, the values of the plastic film (coating) may for example vary between 5 and 400 ?m, optionally between 10 and 200 ?m, even more optionally between 10 and 100 ?m, of coating material (i.e. polythene). The plastic coating material may be chosen, for example, from the following materials: PP, PE (HDPE, LDPE, MDPE, LLDPE), EVA, polyesters (including PET and PETg), PVdC.

The term softening point refers to a thermodynamic state represented by a temperature value at which a material that does not have a defined melting point (for example a plastic material) begins to change its state of aggregation from solid to fluid.

The term heat-sensitive material refers to the property of the material to vary at least one of an optical and physical property following a change in temperature. In particular, the heat-sensitive material used for the container which is the subject of the present invention is configured to vary at least one of an optical and physical property at temperatures higher than room temperature, for example at temperatures equal to or higher than 50 °C.

The term "first closing condition" refers to a condition in which the closing system is arranged for the first time to occlude the passage opening of the warehouse to allow the first and second hook portion to engage. In the first closing condition, the first and second hook portions define the locking condition of the container, to occlude the passage opening of the warehouse. In the locking condition, the first and second hook portions are intact (not damaged) and hinder the passage of the container from the first closing condition to a first opening condition.

The term "first opening condition" refers to the passage of the container, for the first time, into the open condition after it has been placed (for the first time) in the first closed condition. In fact, the first opening condition is defined when the container is placed in the open condition for the first time, after the first and second hook portions have defined the locking condition.

DETAILED DESCRIPTION

Container

With 1? a tamper-evident container made of sheet material, for example paper material, for the containment and/or wrapping of products has been indicated overall.

The container 1 comprises a magazine 2 made of sheet material, optionally paper, extending in thickness between an external surface and an internal surface, respectively delimiting at least part of an external surface of the container and an internal volume 3 configured to house one or more products. The magazine 2 comprises at least one side wall 4 wrapped around itself and engaged at mutually opposite sections to achieve a three-dimensional configuration of the magazine: the stable engagement of the side wall allows the magazine 2 to define the internal volume 3. The side wall can be engaged by means of a glued portion, optionally by means of one or more glue points, for example hot glue or cold glue. Alternatively, the side wall can be glued by means of a glued portion defined by one or more layers of adhesive material, optionally strips of adhesive material, or similar fastening means.

Note how the side wall 4 extends in thickness between an internal surface that at least partially delimits the internal volume 3 and an external surface that separates the internal volume 3 from an environment external to the container.

The warehouse 2 is a closed-profile tubular body, which may have a substantially prismatic shape, for example having a polygonal, rectangular, trapezoidal or cylindrical base. As shown for example in figures 12-16, the warehouse 2 may comprise a front wall 4a and a rear wall 4b facing and parallel to each other: the front wall 4a and the rear wall 4b are connected to each other by means of a first and a second connecting wall 4c, 4d, also facing and parallel to each other. The front wall 4a is spaced apart and opposite the rear wall 4b; the first and second side walls 4c, 4d are also spaced apart and opposite each other. The front and rear walls 4a, 4b have an identical rectangular shape (walls identical in shape and size), similarly the connecting walls 4c, 4d have an identical rectangular shape (walls identical in shape and size).

The front wall 4a and the rear wall 4b are joined as a single piece to the first and second connecting walls 4c, 4d, which have a much smaller extension than the surface extension of the front walls 4a and rear walls 4b. In fact, the ratio between the surface extension of the front wall 4a or the rear wall 4b and the surface extension of the first or second connecting walls 4c, 4d is between 1.5 and 15. The first and second connecting walls 4c, 4d have the function of joining the front wall 4a and the rear wall 4b together, without the need to directly engage the front and rear walls. The first and second connecting walls 4c, 4d, when the container is closed, are therefore interposed between the front wall 4a and the rear wall 4b.

The front, rear and side walls (4a, 4b, 4c, 4d) define two passage openings 5 opposite each other and delimited, in correspondence with the opposite longitudinal end edges, by a respective free edge 6.

Each passage opening 5 defines a respective part of the container 1 intended, in use, for the passage of products, or for the collection and/or insertion of products from/into the container 1. The warehouse 2 may comprise a single passage opening 5 and have at least one of the side walls and a bottom wall, stably closed and engaged together by portions of glue.

As an alternative to what was previously described and in accordance with what is shown for example in figure 11, the magazine 2 can be substantially shaped like an envelope, in which the front wall 4a is folded upwards and overlaps the rear wall 4d, to directly engage the same rear wall 4d.

The front wall 4a may include a recess (shown in the relevant blanks in figures 24-27 with reference 71) defined at the free edge 6, which is configured to define a recess in the free edge to facilitate a user's grip on a closure system 7 (described below) to allow the opening of the container 1. Optionally, the front wall 4a may include a recess defined at each passage opening 5. The recess may have a substantially "C", "U" or "V" shape.

As mentioned above, the container 1 also comprises at least one closing system 7 made of sheet material, optionally paper, arranged in correspondence with each passage opening 5 of the warehouse 2 and configured to occlude a respective passage opening to define a closing condition of the container 1. In particular, the closing system delimits, in cooperation with the warehouse, the internal volume 3 of the container. The closing system 7 is also movable with respect to the warehouse 2 at least between a closing condition of the container, in which it prohibits the passage of products from the passage opening 5, and an open condition of the container, in which it allows the passage of products from the passage opening 5. In fact, the closing system 7 defines a sort of movable lid of the container used to manage, in use, the passage of products from the opening 5.

The closing system 7 comprises a closing portion 9 engaged at the free edge 6 and movable, optionally by rotation, relative to the magazine 2. As shown for example in figure 13, in the closed condition of the container, the closing portion 9 prevents communication between the internal volume 3 of the magazine 2 and the external environment, preventing the passage of at least one product from the passage opening 5, while, in the open condition (figures 12 and 16), the closing portion 9 allows communication between the internal volume 3 and the external environment, therefore allowing the passage of products from the passage opening 5.

The closing portion 9 is made of sheet material, optionally paper, extending in thickness between an internal surface, in continuity with the internal surface of the warehouse 2, delimiting part of the internal volume 3 and an external surface, continuous with the external surface of the warehouse, delimiting part of an external surface of the container.

The closing portion 9 has a polygonal profile, for example rectangular or square in shape, entirely counter-shaped to the free edge 6.

In the configuration of the container 1 featuring two passage openings 5, the container 1 features two closing systems 7 comprising respective closing portions 9 engaged with free edges 6 of the magazine 2 longitudinally opposed to each other. The closing systems 7 are therefore arranged in opposition to each other with respect to the magazine 2 itself, in the form of a tubular body. Each closing system 7 can be joined as a piece to the magazine 2 by means of a closing portion 9 joined as a piece to the free edge 6 and movable by rotation around it. Alternatively, the closing system 7 can be removably engaged with the magazine 2. For example, the closing system 7 can feature a plurality of side walls defining a compartment shaped counter to the passage opening 5, configured to house at least in part the magazine 2 and prevent the insertion and removal of products from the magazine.

The closing system 7 comprises a coupling portion 10 configured to fit, in the closed condition, into the internal volume 3 of the magazine 2, which is engaged with the closing portion 9 at a folded edge 9a opposite the free edge 6. The coupling portion 10 extends from the closing portion 9 and, in the closed condition, is positioned completely within the internal volume 3 of the magazine 2. The coupling portion 10 is also made of a flat sheet of paper material, extending in thickness between an internal surface in continuity with the internal surface of the closing portion 9 facing, in the closed condition of the container, towards a central area of the internal volume, and an external surface in continuity with the external surface of the closing portion 9 which, in the closed condition of the container, faces and is at least partly in contact with the front wall 4a of the magazine 2.

The graft portion 10 may be delimited by a perimeter edge 10a defining a polygonal shape, for example rectangular, square or trapezoidal.

The coupling portion 10 is seamlessly engaged with the closing portion 9 at a folded edge 9a opposite the free edge 6 of the magazine 2, around which the coupling portion 10 is movable by rotation. The coupling portion 10 can be constrained to a section of free edge 6 defined by the rear wall 4b, defining, in cooperation with the closing portion 9, a substantially "L"-shaped shape (see for example figures 12, 16, 20, 21).

The container may comprise at least one control opening 24 defined on the closing system 7 or on the magazine 2, to allow a user to verify the presence and/or engagement between a first and a second hooking portion 12, 13 of the container (these portions will be better described later), prior to the first opening condition of the container (condition following a first closing 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 shape, or an open profile.

If the control opening 24 is defined on the closing system 7 (see for example figures 11-16), this can be entirely present on the engagement portion 10, extending from the folding edge 9a towards a central area of the engagement portion 10 to define a depth of said control opening 24. Alternatively, the control opening 24 can be entirely defined on the closing portion 9, extending from the folding edge 9a towards a central area of the closing portion 9 (towards the free edge section 6 delimited by the rear wall 4b) to define a depth of said control opening 24. If the control opening 24 is defined on the warehouse (as shown for example in figures 20 and 21), this can be present on the front wall 4a of the warehouse 2 and facing, in the closed condition, the first engagement portion 12.

As mentioned above, the container 1 comprises at least a first hook portion 12 carried directly by the closing system 7, optionally by the coupling portion 10, and at least a second hook portion 13 carried directly by the magazine 2, which are configured to stably engage with each other during a first closing condition of the container (see for example figures 14, 15A and 15B). In the closed condition, the first hook portion 12 is entirely contained in the internal volume 3 of the magazine 2 and is spaced from the free edge 6, allowing engagement with the second hook portion 13 entirely in the internal volume 3 of the magazine 2.

The first attachment portion 12 comprises a panel made of a single sheet of paper material, joined in one piece to the insertion portion 10 at a lateral section of the perimeter edge 10a transversal to the folding edge 9a. The panel of the first attachment portion 12 has a surface area that is substantially equal to or smaller than the surface area of the insertion portion 10; in fact, the ratio between the surface area of the insertion portion 10 and the surface area of the panel of the first attachment portion 12 is between 1 and 5.

The panel of the first hook portion 12 extends in thickness between an external surface in continuity with the external surface of the coupling portion 10, and an internal surface in continuity with the internal surface of the coupling portion 10, resulting folded and superimposed on the coupling portion in such a way that the respective internal surfaces of the panel of the first hook portion 12 and of the coupling portion 10 face each other (see for example figures 14, 15A and 15B). The coupling portion 10 is therefore arranged, in the closed condition of the container, in interposition between the front wall of the magazine 2 and the grip tab 12a. The internal surface of the panel of the first hook portion 12 can be engaged to the internal surface of the coupling portion 10, for example by means of an adhesive element such as a glue point or a label, to define at least one constraint portion 12c having a surface extension smaller than a surface extension of the coupling portion. In particular, the ratio between the surface extension of the coupling portion 10 and the surface extension of the constraint portion 12c is between 1.3 and 5, optionally between 2 and 5. The constraint portion 12c can lie on a plane parallel to a plane of the coupling portion 10 and have a polygonal shape, for example triangular, square or trapezoidal.

The first coupling portion 12 may also comprise at least one gripping tongue 12a, adjacent to and integrally joined to a constraint portion 12c, which is designed to cooperate with the second coupling portion 13 to determine a locking condition of the container. The gripping tongue 12a has a polygonal shape, for example square, rectangular or trapezoidal and, like the constraint portion 12c, faces the internal surface of the coupling portion 10, resulting at least partially spaced from the latter. In fact, the gripping tongue 12a lies on a plane transversal to a plane of arrangement of the coupling portion 10. In other words, the gripping tongue 12a of the first coupling portion 12 is inclined with respect to the plane of arrangement of the coupling portion, optionally with respect to the internal surface of the coupling portion, by an angle between 1? and 20?, optionally between 1? and 15?. The gripping tongue 12a defines, in cooperation with the coupling portion 10, a substantially "V" or "U" shaped shape whose concavity, in the closed condition of the container, has a direction exiting from the magazine 2. The gripping tongue 12a has a predetermined surface extension that is smaller than the surface extension of the panel of the first coupling portion 12, but larger than the surface extension of the constraint portion 12c; in fact, the ratio between the surface extension of the protruding portion 12a and the surface extension of the constraint portion 12c is between 0.5 and 5.

The gripping tongue 12a may have a gripping edge 12b spaced from the coupling portion 10 and consequently, spaced from the perimeter edge 10a of the same coupling portion, which is configured to act in abutment against a respective undercut of the second coupling portion 13. As shown for example in figures 15A and 15B and in the related blanks in figures 1 and 9, the first coupling portion 12 may comprise a plurality of gripping tongues 12a, spaced from each other by a constraint portion 12c. The gripping tongues 12a of said plurality may be identical to each other and have the same shape and dimensions. In particular, the first coupling portion 12 may comprise two gripping tongues 12a spaced from each other by means of the constraint portion 12c. Each gripping tab 12a may have a respective gripping edge 12b, spaced from the engagement portion 10 and configured to engage distinct sections of the same undercut of the second engagement portion 13 or two distinct engagement portions.

The first coupling portion 12 may also have at least one notch 46 defined on the panel of the first coupling portion 12, interposed between the constraint portion 12c and the gripping tab 12a, which effectively separates the constraint portion 12c and the gripping tab 12a. The notch 46 may pass through the panel of the first coupling portion 12, extending lengthwise transversely, optionally orthogonally, to the gripping edge 12b of the gripping tab 12a of the first coupling portion 12. It should also be noted how the notch 46, at one longitudinal end, is spaced from the gripping edge 12b of the panel of the first coupling portion 12, so as to allow the gripping tab 12a to distance itself from a surface of the coupling portion 10.

The panel of the first attachment portion may comprise a plurality of notches 46 that are distinct and spaced apart. Two adjacent notches 46 may for example be spaced apart by a length of between 2 mm and 55 mm or, in other words, the ratio between a length of the panel of the first attachment portion 12 measured along the folding edge 9a and the distance between two adjacent notches 46 is between 1.5 and 8. Each notch 46 has a predetermined length along a transverse direction, optionally orthogonal, to the gripping edge 12b, where the ratio between a height of the panel of the first attachment portion 12, measured parallel to the direction of extension of the notch 46 transverse to the gripping edge 12b, and the length of the notch 46 is between 1.1 and 4.

As will be detailed later, the variant of the first hook portion 12 shown in figures 11-16 can be engaged with a second hook portion 13 featuring a removable portion on which a weakening 14 is defined which, following a first opening condition of the container, breaks, allowing for example the separation of the removable portion from the container, to provide evidence of a tampering attempt.

An embodiment of the first attachment portion 12, for example shown in figure 15B (the corresponding rough drawing of which is shown in figure 9), comprises:

- a first portion of the constraint 12c? engaged, optionally by gluing, to an internal surface of the coupling portion 10,

- a first gripping tongue 12a? joined as a single piece and placed next to the first constraint portion 12c?, - a second constraint portion 12c?? spaced apart from the first constraint portion 12c?,

- a second gripping tongue 12a?? joined as a single piece and placed alongside the second constraint portion 12c??, resulting in a distance from both the first constraint portion 12c? and the first gripping tongue 12a?. The first constraint portion 12c? is therefore interposed between the first gripping portion 12a? and the second constraint portion 12c?, while the second constraint portion 12c? is interposed between the first constraint portion 12c? and the second gripping tongue 12a?.

The panel of the first attachment portion 12 may also have a notch 46 placed between the first constraint portion 12c? and the first gripping tongue 12a?, to allow the first gripping tongue 12a? to distance itself from the coupling portion 10. In other words, the first and second constraint portions 12c?, 12c? are engaged in correspondence with a central or internal area of the coupling portion 10, while the first and second gripping tongues 12a?, 12a? are arranged in correspondence with an external area of the coupling portion 10 with respect to the first and second constraint portions 12c?, 12c?, resulting in being opposite to each other.

Note that in this variant, the locking system 7 has a recess (indicated by 71 in figure 9), which has a through opening defined on part of the coupling portion and the panel of the second coupling portion 12, which allows the first and second constraint portions 12c?, 12c? to be spaced apart from each other so that they can be independently constrained, for example by gluing, to the coupling portion 10 and to allow the offset of each gripping tab 12a from the same coupling portion 10.

In a variant embodiment of the container shown in figures 20 and 21, it differs from the variant embodiment shown in figures 11-16, due to the presence of a weakening 14 (identified with 82 in the relevant rough drawing shown in figure 16) defined in a central area of the coupling portion 10 which separates the section of the perimeter edge 10a joined as a single piece to the panel of the second coupling portion 12, from the section of the perimeter edge 9a joined as a single piece to the closing portion 9 of the closing system 7. The weakening 14 can develop along a rectilinear direction which connects two lateral sections of the perimeter edge 10a of the coupling portion 10 or, in accordance with what is shown in figures 20 and 21, the weakening 14 can have a curvilinear shape that surrounds the perimeter edge section 10a that joins the panel of the second attachment portion 12 with the insertion portion 10. The weakening 14 can therefore develop along an open profile trajectory shaped like a ?U?, ?V? or ?L?.

In the embodiment shown in figures 20 and 21, the removable portion is defined by part of the coupling portion 10 joined as a piece to the panel of the second coupling portion 12, which is separable from the remaining part of the coupling portion 10 joined as a piece to the closing portion 9 of the closing system 7, allowing evidence of a tampering attempt following the first opening condition of the container.

A further embodiment of the container shown in figures 20 and 21 and shown in figure 18, provides for the provision of the weakening 14 on the closing portion 9. The removable portion is defined by the panel of the second hooking portion 12, by the coupling portion 10 and by part of the closing portion 9 connected to the coupling portion 10, so that after the first opening condition of the container, the weakening 14 allows its separation. In this configuration, only part of the closing portion 9 hinged to the free edge 6 is integral to the magazine.

A further embodiment shown in the relevant sketch in figure 19 differs from the container shown in figures 20 and 21 due to the presence of a weakening 14 entirely defined on the closing portion 9 and extending along a closed profile trajectory, of circular or polygonal shape, for example square, rectangular or trapezoidal. The weakening 14 shown in figure 19 allows the breaking of the closing portion 9 and consequently to give evidence to a user of an attempted tampering involving the movement of the closing wall 9 in the internal volume 3 of the container. The weakening 14 is therefore configured to break following the application of a force on the closing portion 9 directed towards the internal volume 3 of the warehouse, thus giving evidence of an attempted tampering with the container.

A further embodiment shown for example in figures 37 and 38 and in the related sketch of figure 35, presents a first attachment portion 12 which differs from the attachment portion 12 shown in figures 11-16, due to the presence of a spacer 12d engaged with the panel of the first attachment portion 12. In particular, the spacer 12d is a tab joined integrally to the gripping tab 12a of the second attachment portion 12, folded relative to the latter in such a way as to appear to face the internal surface of the panel of the second attachment portion 12. The spacer 12d is at least partly counter-shaped and overlapped with the gripping tab 12a, resulting interposed between the gripping tab 12a and the engagement portion 10. The spacer 12d can also be glued to the 12a grip tab, increasing its thickness.

The first coupling portion 12 may comprise a plurality of spacers 12d, optionally in an equal number to the number of gripping tabs 12a, so as to further detach the gripping tab 12a from the coupling portion 10, facilitating its engagement with the second coupling portion 13.

A further embodiment shown for example in figures 39 and 40 and in the related sketch of figure 36, presents a first hook portion 12 which differs from the hook portion 12 shown in figures 11-16, due to the presence of a support tab 12f joined as a piece to the constraint portion 12c of the second hook portion 12 and facing the external surface of the panel itself. When the container is closed, the support tab 12f is facing the second hook portion 13, so that the latter is interposed between the support tab 12f and the panel of the second hook portion 12. In this way, if a user attempts to tamper with the container by moving the closing portion 9 towards the internal volume of the warehouse 2, the support tab 12f forces the breaking of the weakening 14 defined on the second hook portion 13. In other words, the support tab 12f hinders the insertion of the closing portion 9 of the closing system 7 without breaking the weakening 14.

A further variant of the first coupling portion 12, the blank of which is shown in figure 34, has the panel of the first coupling portion 12 which differs from the panel of the first coupling portion 12 shown in figures 11-16, in that it is engaged with at least one lateral section of the perimeter edge 10a of the coupling portion 10. The panel of the first coupling portion 12 is joined in one piece to a single lateral section of the perimeter edge 10a of the coupling portion 10 and is configured to overlap above the internal surface of the coupling portion 10. It should also be noted that the panel of the first coupling portion 12 has a further constraint portion 12c which extends along the entire length of the panel and is designed to engage the coupling portion 10. In this case, the panel of the first coupling portion 12 has a surface extension substantially equal to the coupling portion 10.

A further variant of the first coupling portion 12, the blank of which is shown in figure 31, features a first coupling portion 12 having two panels joined in one piece to respective lateral sections of the perimeter edge 10a of the coupling portion 10, both of which are superimposed and constrained to the internal surface of the coupling portion 10.

A further embodiment of the first attachment portion 12 shown in the blank of figure 33 differs from the first attachment portion 12 shown in figure 15B due to the presence of a recess (indicated with 71) defined exclusively on the panel of the second attachment portion 12, unlike the recess shown in the configuration of figure 15B and in the related blank of figure 9, defined on the panel of the second attachment portion 12 and on the coupling portion 10.

In a variant embodiment not shown in the attached figures, the panel of the first attachment portion 12 can be superimposed and facing the external surface of the coupling portion 10. The constraint portion 12c can therefore be engaged with the external surface of the coupling portion 10 and the gripping tongue 12a is spaced from the external surface of the coupling portion by an angle between 1? and 20?, optionally between 1? and 15?.

Moving now to describe the second attachment portion 13 and referring to figures 11-16, this comprises a locking tab 13a coplanar to a plane of the front wall 4a of the warehouse 2 and configured to delimit, in cooperation with the side walls, the internal volume 3 of the warehouse (see for example figures 11, 13-16). As shown in the attached figures, the container comprises a through-cut 13c defined on the side wall of the warehouse which carries the second attachment portion 13 and configured to delimit the locking tab 13a at the bottom which is therefore interposed between a section of the free edge 6 and the through-cut 13c. The through-cut 13c can develop along the entire width of the front wall 4a, starting from the first connecting wall 4c up to the second connecting wall 4d (see for example figure 16), along a direction parallel to the freeboard section defined by the front wall 4a. Alternatively, the through-notch 13c develops along a predominant part of the width of the front wall 4a, resulting spaced from the first and second connecting walls 4c, 4d (see for example figure 6). In other words, the ratio between the width of the front wall 4a and the length of the through-notch 13c is between 0.2 and 1.

The 13c through notch also defines:

- a gripping edge 13b of the locking tab 13a, which may be parallel and spaced from the free edge 6 of the magazine and configured to engage the first engaging portion 12,

- a passage suitable for receiving the coupling portion 10 and the first coupling portion 12 through it to allow their engagement with the second coupling portion 13.

The locking tab 13a has a predetermined height defined by the minimum distance between the gripping edge 13b and the free edge 6 of the magazine 2, greater than 2 mm, optionally between 3 mm and 30 mm, even more optionally between 3 mm and 20 mm.

As previously mentioned, the second latching portion 13 has a removable portion at least partly defined by the locking tab 13a and configured to break and/or separate from the container following the first opening condition of the container to provide evidence of a tampering attempt.

To further facilitate the breaking of the locking tab 13a and as shown for example in figure 16, the second hook portion 13 may comprise at least one weakening 14 defined by a cut on the locking tab 13a transversal to a section of the free edge 6 and extending along the entire height of the locking tab 13a, i.e. starting from the through notch 13c up to the free edge 6. The weakening 14 may be created in a central area of the locking tab 13a, aligned with a mid-plane of the side wall 4 of the container carrying the second hook portion 13 to allow the breaking of the locking tab 13a into two panels of equal dimensions. However, it is possible to provide for the creation of a lateral weakening, close to a respective folding edge between the front wall 4a and one between the first and second connecting walls 4c, 4d.

After the first opening condition of the container and the consequent breakage or separation of the locking tab 13a of the second coupling portion 13, a user can verify that the container has been tampered with, for example when it is returned to the closed condition, by checking the absence of the locking tab through the control opening 24, which will directly show the internal volume 3 of the magazine 2. It should therefore be noted how the control opening 24 can be made, for example, on the coupling portion 10, resulting, in the first closing condition of the container, in a position 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 for the first time.

Further embodiments of the second attachment portion 13 that allow for the engagement of a first attachment portion 12 featuring the previously described structure are shown in figures 3-5 and 7, which have respective structural characteristics that differ from the second attachment portion 13 described previously, but which equally allow for engagement with the first attachment portion described previously and shown in figures 11-16.

In particular, the variant of the second attachment portion 13 shown in figure 3 has a locking tab 13a ? made by means of an upper notch 13c? and a lower notch 13c? defined on the front wall 4a along sections that are parallel to each other and spaced from the free edge of the magazine 2. The upper notch and the lower notch 13c?, 13c? may have the same length extending across the entire transverse bulk of the front wall 4a or they may have a reduced length, resulting in being spaced from the folding edges of the front wall 4a with the first and second connecting walls 4c, 4d respectively.

The lower notch 13c? defines a passage suitable for receiving the coupling portion 10 and the first hooking portion 12 through each other to allow the latter to engage with the locking tab 13a of the second hooking portion 13. The locking tab 13a is therefore spaced from the free edge by a distance greater than 2 mm, optionally between 3 mm and 15 mm. Note that this distance substantially 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 between 6 mm and 45 mm. In the embodiment shown in figure 4, the second hooking portion 13 may have a protrusion 25 carried by the removable portion which, in the embodiment shown in figure 4, is spaced from the free edge 6 by a distance greater than 4 mm. at least partly defined by the locking tab 13a. In practice, the protrusion 25 defines a protuberance that, in the first closed condition of the container, emerges externally from the container itself to be perceived by touch. In the first closed condition of the container, the control opening 24 is configured to allow the passage of the protrusion 25 and therefore the exit from the magazine 2. Note how the protrusion 25 provides additional information to the user of a tactile and not exclusively visual type, allowing even blind users to verify the integrity of the container.

The variant of the second hook portion 13 shown in figure 5, has a structure that differs from the structure of the second hook portion 13 shown in figures 3, 11-16, due to the presence of a through notch 13c comprising two end sections 13e defined on the locking tab 13a that develop transversely, optionally orthogonally, to the free edge 6. Each end section 13e is spaced from the free edge 6, having a height measured along a direction orthogonal to the free edge, lower than the height of the locking tab 13a. The end sections 13e are opposed to each other with respect to the centre plane, defining points of weakness to facilitate the breakage/separation of the locking tab 13a following the first opening condition of the container.

A further variant of the second attachment portion 13 is shown in figure 7, which differs from the second attachment portion 13 of figure 5 due to the presence of a through notch 13c extending between two ends respectively coinciding with the extreme sections 13e. In this embodiment, the through notch 13c is spaced from the folding edges of the front wall 4a respectively with the first and second connecting walls 4c, 4d.

In the embodiments shown in figures 5 and 7, the control opening 24 can be created in correspondence with the lateral areas of the coupling portion 10 and of the panel of the second coupling portion 12 (figure 2), resulting, in the first closed condition of the container, in front of the respective extreme sections 13e of the locking tab 13a.

Note how the variants of the second hook portion 13 shown in figures 3-5 and 7 can be used with the variants of the first hook portion 12 shown in figures 11-16, 20, 21, 37-40 and with the variants of the first hook portion 12 obtainable by folding the blanks shown in figures 2, 6, 9, 31, 33, 34.

A further variant of the second attachment portion 13, for example shown in figure 8, may have a locking tab 13a defined by a through-cut 13c having two distinct sections aligned along the same direction parallel to the free edge section defined by the front wall 4a. Note how the minimum distance between two adjacent ends of the two sections of the through-cut is less than a minimum distance between the two cuts 46 which respectively delimit the first constraint portion 12c? with the first grip tab 12a? and the second constraint portion 12c? with the second grip tab 12a?, thus allowing the insertion of the first and second grip tabs 12a? and 12a? in a respective cut. A further variant of the second attachment portion 13 not shown in the attached figures and which allows engagement with the variant of the first attachment portion 12 shown in figure 15B, comprises a through notch 13c presenting two pairs of parallel sections, opposite with respect to a mid-plane of the front wall 4a orthogonal to a section of the free edge 6 defined by the same front wall 4a. In this embodiment, the sections of each pair of sections extend along rectilinear directions parallel to each other.

This last variant of the second hook portion 13 and the embodiment of figure 8 can be engaged with the variant of the first hook portion 12 shown in figure 15B and in the first hook portion obtained by bending the blanks shown in figures 9, 31 and 33.

In a variant embodiment of the second coupling portion 13 shown in figures 20 and 21, it differs from the variant previously described and shown for example in figures 11-16, due to the presence of a second coupling portion 13 with a locking tab 13a having a height greater than the height of the locking tab 13a previously described. In fact, the locking tab 13a can have a height measured along a direction orthogonal to the free edge section defined by the front wall 4a, with dimensions between 30 mm and 60 mm, optionally between 30 mm and 55 mm. The engagement between the first and second coupling portions 12, 13 occurs in the same way as previously described, while still remaining the possibility of checking, by means of the control opening 24, the presence or absence of the part of the coupling portion 10 removable from the closing system 7.

A further variant of the second attachment portion 13 shown in the blanks of Figures 30 and 32, which differs from the embodiment shown in Figures 28 and 29 in having a through opening defined on the panel of the second attachment portion 13 that separates the locking tab 13a from the free edge 6 that allows the insertion of the first attachment portion 12 to engage inside it. The second attachment portion 13 may also have two or more through openings defined on the panel of the second attachment portion 13, distinct and spaced from each other and configured to allow the insertion of the variant of the first attachment portion 12 shown in Figures 9, 15B, 31 and 33.

In the embodiments of the second coupling portion shown in figures 30 and 31, the control opening 24 can be made on the front wall 4a of the magazine 2 and on the coupling portion 10, in a manner completely analogous to that shown in the sketch of figure 23.

A further variant of the container shown in figure 44 and in the related draft of figure 43, differs from the container shown in figure 42 and in the related draft of figure 41, due to the presence of a locking tab 13a presenting oblique weakenings 14, which are interposed between the through-cut 13c and the free edge 6 and inclined with respect to the through-cut 13c by an angle between 5? and 50?, optionally between 8? and 45?. It should also be noted how the weakenings 14 extend along the entire height of the locking tab 13a and are symmetrical with respect to a centre plane of the front wall 4a orthogonal to the section of the free edge 6 defined by the front wall 4a.

This embodiment can be combined with variations of the first attachment portion 12 shown in figures 2, 6, 9, 11-16, 18-21, 31 and 33.

In the embodiment shown in figure 44 (sketch figure 43), the control opening 24 can be created in correspondence with the lateral areas of the coupling portion 10 which, in the first closed condition of the container, face a respective weakening 14.

A further variant of the container, for example shown in figure 42 and in the related draft of figure 41, has a second attachment portion 13 which differs from the second attachment portion 13 described in figures 11-16, due to the presence of a support element 19 engaged with the locking tab 13a by means of a weakening coinciding with a section of the free edge 6. The support element 19 is folded with respect to said weakening in the internal volume of the magazine 2 and bound, for example by glue, to the internal surface of the magazine in correspondence with an area of the same support element 19 opposite to the aforementioned section of free edge 6.

Note how the panel of the first hook portion 12, in the closed condition of the container, is interposed between the coupling portion 10 and the support element 19, which supports the locking tab 13a both during the insertion phase of the panel of the first hook portion 12 and during the extraction of the latter, keeping the first hook portion 12 engaged with the second hook portion 13. In other words, the support element 19, by preventing the movement of the panel of the hook portion 12, prevents attempts to tamper with the container that involve the insertion of tools through the control openings 24.

Subsequent to the first opening condition of the container, the weakening of the support element 19 is configured to break at the weakened section coinciding with the free edge 6, allowing the separation of the locking tab 13a from the magazine.

In the embodiment shown in figure 42, the container can have a first hook portion 12 structurally shaped like any of the first hook portions 12 shown in figures 11-16, 20, 21, 37-40 or a variant of the first hook portion 12 obtainable by folding the blanks shown in figures 2, 6, 9, 31, 33, 34, while it can have a second hook portion 13 shaped like any of the hook portions 13 shown in figures 3-5, 7, 8, 11-16, 20, 21, 24-29, 32. In the embodiment shown in figure 42, the control opening 24 can have a first hook portion 12 structurally shaped like any of the first hook portions 12 shown in figures 11-16, 20, 21, 37-40 or a variant of the first hook portion 12 obtainable by folding the blanks shown in figures 2, 6, 9, 31, 33, 34, while it can have a second hook portion 13 shaped like any of the hook portions 13 shown in figures 3-5, 7, 8, 11-16, 20, 21, 24-29, 32. be made on the coupling portion 10 and/or on the magazine depending on the selected embodiment of the first and second coupling portion 12, 13, so as to face, in the first closed condition of the container, the removable portion. A further variant of the container shown in figures 46-48 and in the related sketch of figure 45, has a locking tab 13a of the second coupling portion 13 coplanar to a plane of the front wall 4a of the magazine 2 and configured to delimit, in cooperation with the side walls, the internal volume 3 of the magazine.

The locking tab 13a is made from a through-cut 13c made on the front wall 4a of the magazine 2, which defines a through-access to allow the insertion of the coupling portion 10 into the internal volume 3 of the magazine and the consequent engagement between the first coupling portion 12 and the locking tab 13a of the second coupling portion 13. In detail, the through-cut 13c has:

- at least one upper section 20a spaced from the free edge 6 warehouse 2,

- at least one lowered section 20b joined to the upper section and extending away from the free edge of the warehouse 2.

The through notch 13c may also have two opposing upper sections 20a, between which there is the lowered section 20b which joins the upper sections 20a together. The upper sections 20a may develop along respective rectilinear directions, orthogonal to the free edge 6 of the warehouse 2 and symmetrical with respect to a centre plane of the container orthogonal to the free edge section 6 defined by the front wall 4a. The lowered section 20b instead has a convex shape, for example having a ?C? or ?U? shape, with the concavity facing the free edge of the warehouse 2.

The locking tab 13a can be shaped counter-to the through notch 13c and delimited, on the opposite side to the free edge 6, by:

- at least one grip section coinciding with the upper section 20a of the through notch 13c, which defines at least part of the grip edge 13b configured to engage, in the first closing condition, the grip tab 12a of the first hook portion 12,

- a lowered section coinciding with the lowered section 20b of the through notch 13c, which is joined to the grip section and extends away from the latter.

Since the gripping section defining the gripping edge 13b coincides with each upper section 20a of the through notch 13c, the locking tab 13a may have two or more gripping edges 13b shaped counter-to a respective upper section 20a, each of which is configured to engage a respective gripping tab 12a of the first hooking portion 12. Note how only the gripping edge 13b of the locking tab 13a defined by the gripping section is configured to engage the first hooking portion 12 in the first closed condition of the container, while the lowered section is, in the closed condition of the container, spaced from the gripping edge 13b.

As previously mentioned, the locking tab 13a can be shaped counter-to the through notch 13c and directly constrained to the magazine at least by means of a first and a second attachment portion 22a, 22b defining a weakening 14 configured to break during the first opening condition of the container. In particular, the locking tab 13a is constrained to a section of the free edge 6 of the magazine by means of the first attachment portion 22a, and is constrained to the front wall 4a of the magazine 2 by means of the second attachment portion 22b.

Moving now on to describe the engagement between the first and second hook portions 12, 13 in accordance with what is shown for example in figure 46, the coupling portion 10 is partially insertable in the passage defined by the through notch 13c, in interposition between the front wall 4a of the magazine and the locking tab 13a. Note how the coupling portion 10 is only partially superimposed on the locking tab 13a, leaving a surface of the locking tab 13a exposed. In other words ... spaced from the second attachment portion 22b, in which at least a part of the lowered section 20b, together with the coupling portion 10 define, in the first closed condition of the container, a control opening 23 configured to allow the viewing, from the outside of the container, of a part of the lower portion of the locking tab joined to the side wall of the magazine by means of said second attachment portion 22b.

The control opening 23 may be spaced from the free edge 6 to allow, following the first opening condition of the container, the viewing of the outside of the container, the internal volume of the magazine or the damage or breakage of the weakening 14. If the container has not been subjected to an attempted tampering, the control opening 23 allows the viewing of the locking tab 13a, allowing a user to verify the integrity of the container. To facilitate the user's verification of the presence of the locking tab 13a, the area of the locking tab 13a itself defined in correspondence with the control opening 23, may have a color different from a color of the magazine 2 or of the coupling portion 10. If the container has been subjected to an attempted tampering resulting in the breakage of the locking tab 13a, the control opening 23 allows the separation of the locking tab 13a from the magazine 2 to be verified, providing evidence of tampering.

Note how the variants of the second hook portion 13 shown in figures 46-49 can be combined with the variants of the first hook portion 12 shown in figures 11-16, 20, 21, 37-40 and with the variants of the first hook portion 12 obtainable by folding the blanks shown in figures 2, 6, 9, 31, 33, 34.

A further variant of the second attachment portion 13 shown in figures 28-29 is defined by a base body 35 engaged with a side wall of the warehouse 2 inside the internal volume 3. In this configuration, the second attachment portion 13 can be directly engaged with the warehouse 2, for example by means of a glued portion, or it can be joined as a single piece to a section of free edge 6 and folded relative to the latter in the internal volume 3 of the warehouse itself. Note how the base body 35 of the second attachment portion 13 is engaged with the front wall 4a of the warehouse, resulting in it facing the first attachment portion 12 at least after the first closed condition of the container. The second attachment portion 13 can have a locking tab 13a which engages, in the closed condition of the container, the first attachment portion 12, defining the locking condition. Differently from what was previously described, the locking tongue 13a extends on a plane of arrangement parallel to a plane of arrangement of the front wall 4a of the magazine 2; the locking tongue 13a is therefore facing the internal surface of the magazine 2. The locking tongue 13a is defined by at least one through-cut 13c made on the base body 35 of the second coupling portion 13, which allows the coupling portion 10 and the first coupling portion 12 to be received through-cut for engagement with the second coupling portion 13. The through-cut 13c also defines a gripping edge 13b which delimits the locking tongue 13a at the bottom and is configured to engage with the first engagement 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 between 3 mm and 30 mm.

Note how the variants of the second hook portion 13 shown in figures 28 and 29 can be used with the variants of the first hook portion 12 shown in figures 11-16, 20, 21, 37-40 and with the variants of the first hook portion 12 obtainable by folding the blanks shown in figures 2, 6, 9, 31, 33, 34.

Always referring to the variant of the second coupling portion shown in figures 28 and 29, the control opening 24 can be made on the front wall 4a of the magazine 2 and on the coupling portion 10, in a manner completely analogous to that shown in the sketch of figure 23.

Further variants of the second hook portion 13 shown in the relevant blanks in figures 24-27 have a locking tab 13a which may have an identical shape to the locking tab 13a previously described and shown in figures 3-5, 7 and 8, with the only difference being that it is made on the base body 35 of the second hook portion 13 engaged with the internal surface of the front wall 4a of the magazine.

The variants of the second hook portion 13 obtainable by folding the relevant blanks shown in figures 24-26 can be combined with variants of the first hook portion 12 shown in figures 11-15A, 16, 20, 21, 37-40 and with the variants of the first hook portion 12 obtainable by folding the blanks shown in figures 2, 6, 34.

The variant shown in the blank of figure 27 can be combined with the variant of the first hook portion 12 shown in figure 15B and with the variants of the first hook portion 12 obtainable by folding the blanks shown in figures 9, 31 and 33.

Even in the embodiments of the second coupling portion shown in figures 24-27, the control opening 24 can be made on the front wall 4a of the magazine 2 and on the coupling portion 10, in a manner completely analogous to that shown in the rough drawing in figure 23.

In a variant embodiment shown in the relevant sketch of figure 23, the container comprises one or more lateral tabs 8 (indicated in the figure with the reference 61), each of which is engaged with a respective one between the first and second connecting walls 4c, 4d by means of a weakening.

Each lateral tab 8, at least in the first closing condition of the container, is folded into the internal compartment of the container and faces the closing portion 9. The closing tabs 8 can define respective second hooking portions 13 which, when folded into the internal volume 3 and in contact with a respective grip tab 12a of the first hooking portion 12, define the locking condition of the container.

In this embodiment, the removable portion is defined by each of the lateral tabs 8, which are configured to break and separate from the magazine after the first opening condition of the container to give a user evidence of tampering. In fact, the lateral tabs 8 are engaged with a respective lateral connecting wall 4c, 4d of the magazine 2, by means of the weakening 14 to allow, during the first opening condition, the separation of each lateral tab from the container. In a further embodiment, the container may comprise a layer of heat-sensitive material configured to irreversibly vary at least one of a property of the container. optical and physical properties of the same layer to provide evidence of an attempted tampering with the container, in accordance with what is described in the European patent application No.22177459.9 from page 20, line 11 to page 22, line 2 and in the corresponding Italian patent application No.102021000020438 from page 20, line 13 to page 21, line 13.

Procedure for making container 1

The present invention also relates to a process for manufacturing a container 1 in accordance with one or more of the appended claims and/or with the description given above.

The procedure involves the preparation of the warehouse 2 which, as described above, is made of sheet material, optionally paper. This phase involves the preparation of 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 also comprises at least a first and a second lateral connecting portion 55, 56. As can be seen for example in figures 1, 10, 17, 22, 30, 41, 43 and 45, 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 connecting portion 56 and the central connecting portion 53, while the second portion 54 is interposed between the first and second lateral connecting portion 56 and the central connecting portion 53. interposed between the second lateral connecting 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 connecting portions 55, 56 also have a substantially identical rectangular shape. 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 connecting portions 55, 56 are joined along the longitudinal edges and aligned along a single connection direction.

The preparation phase of the magazine 2 includes a folding phase of the first sheet 51 at the lateral edges of the portions 52, 53, 54, 55 and 56 in such a way as to join together the lateral connecting portions 55, 56. The first sheet is rolled up on itself in such a way as to bring into contact (overlap) the lateral connecting portions 55 and 56. In order to maintain the magazine 2 in the folded three-dimensional shape, the process may include, in a non-limiting way, the application of a pre-established quantity of glue, for example a cold glue, on at least one of the longitudinal connecting portions 55, 56 suitable for abutting each other: the union of said portions allows the magazine 2 to be blocked in the folded configuration. In the attached figures, a non-limiting way has been illustrated a process that includes the application of a pre-established quantity of glue only on one longitudinal connecting portion. The possibility of applying glue to both portions 55 and 56 is not excluded.

The process also includes the preparation of the closing system 7. This step includes the preparation of at least one second sheet 57, joined as a piece to the first sheet 51 in correspondence with an extreme edge of the first and/or second portion 52, 54 of the first sheet 51. The second sheet 57 comprises at least a first and a second portion 58, 59 joined as a piece to each other: the first portion 58 of the second sheet 57 is connected to the first sheet 51 in such a way that said first portion 58 is interposed between the second portion 59 of the second sheet 57 and the first sheet 51. The attached figures illustrate a preferential, but not limitative, configuration of the invention, in which the preparation of two second sheets 57 engaged with the first sheet 51 and arranged in opposition to the latter is envisaged. Each second sheet 57 is for example connected to a respective extreme edge of the first and/or second portion 52, 54 of the first sheet 51. The process also includes folding phases of the first and second portion 58, 59 of the second sheet 57 to form respectively the closing portion 9 and the engagement portion 10 of the closing system 7. The folding phase of the second sheet is preferably but not limited to the engagement of the portions 55 and 56 of the first sheet 51.

The preparation phase of the closing system 7 may also include a sub-phase for the preparation of at least one portion 61 connected to at least one central and/or lateral connection portion of the first sheet 51 and emerging from the latter on the same side from which the second sheet 57 emerges. The process may include the preparation of two portions 61 connected to the central connection portion 53 and emerging from the latter in opposition to each other along respective extreme edges (emerging from the first sheet 51 on the same side from which the second sheet 57 emerges). The process may also include the preparation of two further portions 61 connected to the second lateral connection portion 56 and emerging from the latter in opposition to each other along respective extreme edges (emerging from the first sheet 51 on the same side from which the second sheet 57 emerges). Each portion 61 may be engaged at the central connecting portion 53 and at the second lateral portion 56 by means of a weakening capable of allowing the separation of each portion 61 following a first opening condition of the container.

Note how the first portion 52 of the first sheet, the second portion 54 of the first sheet, the second lateral connecting portion 55 of the first sheet, the first portion 58 of the second sheet 57, may comprise at least one covering 70 in heat-sensitive material, which, following the formation of the magazine 2, defines at least a part of an external surface of the container 1, opposite to the at least one glued portion of the same, to define a layer in heat-sensitive material.

The process may also include a formation phase, on each second sheet 57, of 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 portion 58, 59 of the second sheet 57, configured to define the control opening 24. The notch 69 is performed substantially in correspondence with a connecting edge between the first and second portion 58, 59 of the second sheet 57.

The process may also include a step for creating a notch 80 on the second portion 54 of the first sheet 51 to define the gripping edge 13b of the locking tab 13a of the second attachment portion 13. Furthermore, the process may include the creation of end notches 88 made on the second portion 54 of the first sheet 51 at opposite ends of the notch 80 to define the attachment portion 22a, as well as the creation of a weakened portion 89 made on the notch 80 to define the weakened portion 22b of the second attachment portion 13 (figure 45).

The method may also include the preparation of a third sheet 62 comprising at least one panel 62a joined integrally to the second portion 59 of the second sheet 57. The panel 62a of the third sheet 62 is made of sheet material, optionally of paper sheet material, and emerges longitudinally from the second sheet 57 on the opposite side to the first sheet 51: the panel 62a of the third sheet 62 is configured to define the first attachment portion 12 of the container 1. To form the first attachment portion 12, the method includes a step of folding and constraining, for example by gluing, the panel 62a with respect to the second portion 59 of the second sheet 57, as well as a further step of making notches 83 on the same panel 62a of the third sheet 62 to define the constraint portion 12c and the grip tab 12a of the first attachment portion 12.

The third sheet 62 may also comprise at least one auxiliary tab 62b joined integrally to the panel 62a, which is made of paper sheet material and emerges longitudinally from the same panel 62a on the side opposite the second portion 59 of the second sheet 57.

In a variant embodiment shown in the sketch of figure 35, for the formation of the first attachment portion 12, the process involves a phase of folding and constraining, for example by gluing, each auxiliary tab 62b with respect to the panel 62a, in such a way that each auxiliary tab 62b is, after the formation of the container, interposed between the auxiliary tab 62a and the second portion 59 of the second sheet 57.

In a variant embodiment shown in figure 38, the auxiliary tab 62b is exclusively folded with respect to the panel 62a of the third sheet 62, resulting, subsequently in the formation of the container, in it facing the same panel 62a of the third sheet 62.

In accordance with the rough drawing of an embodiment of the container shown in figure 17, the procedure involves the creation of a weakening section 82 on the second portion 59 of the second sheet 57 to create the weakening 14.

Note how this embodiment differs from the embodiment shown in figures 1 and 10 in that a cutout 69 is made on at least one of the second portion 54 of the first sheet 51, the first portion 58 of the second sheet 57, the second portion 59 of the second sheet 57, the panel 62a of the third sheet 62 and one or more auxiliary sheets 61, to define the control opening 24.

In accordance with the present embodiment, the process may also include the creation of a weakening section 82 on the first portion 58 of the second sheet 57 to create the weakening 14 (figures 18 and 19).

In accordance with the sketch of a further embodiment of the invention shown in figures 21 and 25, the process may include a phase of forming on the first sheet 51 at least one recess 71 on the first and/or second portion 52, 54 and configured to define the recess. The recess 71 is substantially formed in correspondence with the lower and/or upper edge of at least one of said portions 52, 54, defining an open profile having a substantially “C” or “U” or “V” shape.

The process may include the preparation of at least a fourth sheet 63 emerging laterally from the first sheet 51 to the side of the second portion 54 of the same first sheet 51. The fourth sheet 63 may comprise at least a portion 63a directly joined as a whole to the second portion 54 of the first sheet 51, which is folded and constrained, for example by gluing, to the same second portion 54 of the first sheet 51.
