DESCRIPTION

attached to a patent application for an INDUSTRIAL INVENTION PATENT entitled:

"CHILD-PROOF PACKAGING AND PROCEDURE FOR MAKING THE SAME, METHOD OF CLOSING AND OPENING THIS PACKAGE"

FIELD OF THE TROVATO

The present invention relates to a child-resistant package and a process for making it, as well as a method of closing and opening the package. The packaging can be used in sectors that provide for the packaging of products in which, for safety reasons, the inhibition of opening the package by children is required. For example, the package can be used in the packaging sector for various kinds of products such as: drugs, cosmetics, cleaning products (laundry and tableware detergents), food and tobacco-based products (cigars and cigarettes).

STATE OF THE ART

As is known, child-proof packs are available on the market designed to be difficult to open by a majority of children under the age of 5; this type of packaging is used to prevent children of reduced age from coming into contact with products that are potentially harmful to them.

A first known type of child-resistant packaging provides a wrapper made of paper material having a box-like shape suitable for receiving inside a blister made of plastic material intended to contain a plurality of products. The envelope has, in correspondence with opposite longitudinal side walls, two slits which are also arranged along a diagonal of the container itself. The blister has a rectangular shape and includes two protrusions suitable for inserting and completely crossing the respective slots of the wrapping: in the condition in which the blister is housed in the wrapping, the engagement of the protrusions with the slots prevents the blister from being extracted by means of a only shooting action of the same. If you want to remove the blister from the wrapping, it is necessary to press the protrusions in order to push them towards the inside of the wrapping itself and cause them to disengage from the slots; at this point, it is possible to remove the blister from the wrapper.

Although these packages have a particular opening system designed to prevent access to the blister, the Applicant has found that these packages are not free from limitations and drawbacks. In fact, the packages described above define a closure by means of the cooperation between the wrapper and the blister; this feature makes the packages not very flexible in their use. In order to be able to define a childproof safety system, a wrapper can only receive a blister specially designed and manufactured for that particular wrapper. The blisters must therefore be made using specific production methods, preventing them from being made using standard production machinery. The blisters of the packages described therefore have a rather complex structure, which negatively affects production and product costs.

A second type of child-resistant package is described in the PCT patent application n. WO 2017/216662 A1 of the same Applicant. The package includes a casing with a passage opening and an engagement portion emerging inside the casing itself. The package further comprises a container for housing products and configured to be inserted inside the envelope and, by means of an abutment element, engage with the engagement portion to allow the container to be locked inside the envelope and consequently prevent the withdrawal of products. The disengagement between the wrapper and the container takes place following the insertion of an opening device inside the package.

Although the package described in the aforementioned patent application no. WO 2017/216662 A1 defines an improved child-resistant system with respect to packages of the first type as it is structurally simpler and more flexible in use, the Applicant has found that these packages also have improved safety (locking) systems.

PURPOSE OF THE FIND

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

An object of the present invention is to provide a package that is flexible in its use and has a highly effective safety system capable of preventing the opening of the package by children but which at the same time can be easily opened for an adult. It is also an object of the present invention to provide a package having a structure, and in particular a safety device, which is difficult for children to manipulate and therefore capable of preventing its correct grip for opening the package.

It is also an object of the present invention to provide a package having a simple and compact structure, which can be produced quickly and economically. It is also an object of the present invention to provide a package having a stable structure capable of guaranteeing its integrity following multiple openings and closings thereof.

It is also an object of the present invention to provide a method of opening a package that can be easily carried out by an adult but which is impracticable by a child.

These objects and others besides, which will become more apparent from the following description, are substantially achieved by a package, a method of manufacturing the package and a method of closing and opening the same in accordance with what is expressed in one or more of the attached claims and / or of the following aspects, taken alone or in any combination with each other or in combination with any of the appended claims and / or in combination with any of the further aspects or features described below.

DETAILED DESCRIPTION

Pack of 100

A total of 100 indicates a child-resistant package for containing products which can be applied in all sectors that require, for safety reasons, the inhibition of the opening of the same package by children; for example, the package 100 can be used to contain: drugs, cosmetics, cleaning products (detergents for linen and dishes), food and tobacco-based products (cigars and cigarettes).

As visible from figures 3 to 8, the package 100 comprises a container 1 in sheet material, for example in paper material, defining a compartment 3 for housing at least one product. The container 1 has a predetermined number of side walls 4 defining at least one opening 5 delimited by a free edge 6: the opening 5 is configured to allow the insertion and withdrawal of the product from the container 1.

The container 1 can have a quadrangular prismatic shape as illustrated in the accompanying figures, although not excluding the possibility of making a container 1 having a different shape, for example square, trapezoidal or cylindrical. In detail, the container 1 can comprise a front side wall 4a and a rear side wall 4b facing each other 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 side wall 4c, 4d, also facing and parallel to each other. The front wall 4a is spaced from and opposite to the rear wall 4b; the first and second side walls 4c, 4d are also spaced apart and opposite each other. The ends of the front, rear and side walls (4a, 4b, 4c, 4d) define the opening 5, delimited by the free edge 6.

The container 1 also comprises a bottom wall 9 having a rectangular shape and from which, starting from a perimeter edge of the bottom wall 9, the side walls 4 and in particular the front wall 4a, the rear wall 4b and the first and second side part 4c, 4d. The container 1 therefore comprises a single opening 5 defined in opposition to the bottom wall 9. However, the possibility of making a container 1 having two or more openings 5 is not excluded.

The compartment 3 of the container can have a volume greater than 40 cm³, optionally greater than 100 cm³ depending on the products to be contained. For example, if the container 1 is used to contain medium-sized products, the compartment 3 can have a volume between 800 and 1,400 cm³. For large products, compartment 3 can reach volumes greater than 10,000 cm³.

The package 100 also comprises an envelope 102 which can also be made of sheet material, for example paper, and has a predetermined number of side walls 104 defining at least one access 105 delimited by a free edge 106 configured to allow the container 1 to pass through. The predetermined number of side walls 104 of the envelope 102 delimits an internal volume 103 configured to receive at least part of the container 1; in fact, access 105 is configured to put the internal volume 103 in communication with the external environment, as well as to allow the insertion and removal of the container 1 from said internal volume 103.

The casing 102 and the container 1 are defined by elements that are distinct from each other and completely separable as shown schematically in figure 2. In particular, the casing 102 and the container 1 are relatively movable with respect to each other at least between: - a closed condition in which the envelope 102 closes the opening 5 of the container 1, and

- an open condition in which the casing 102 allows communication between the compartment 3 and the external environment.

The relative movement between the casing and the container can be obtained by moving both parts, i.e. both the casing and the container, or it can be obtained by moving only one of the parts: for example, it is possible to keep the container fixed and only move the container. casing relative to the container.

In detail, the container 1, in the closed condition (schematized for example in Figures 7 and 8), is arranged at least in part in the internal volume 103: the envelope 102, in this condition, prohibits the insertion and removal of products from the container. In the open condition, the casing 102 is completely separated (spaced apart) from the container 1 as can be seen for example in Figure 2. During the transition from the closed to the open condition, and vice versa, the container 1 and the casing slide relative to each other. to the other approaching or moving away from each other: during this relative movement, the container is placed at least in part inside the casing and moves relatively (by moving at least one of said container and casing) in a manner such that the bottom wall 9 of the container 1 and the top walls 109 of the casing 102 approach or move away from each other.

The casing 102 has a structure at least partially counter-shaped to the container 1 so that, in the closed condition, the casing 102 is fitted externally to the container 1. In detail, the casing 102 comprises a front wall 104a and a wall rear 104b opposite each other and connected by means of a first and a second side walls 104c and 104d, which are also spaced apart and opposite each other. In detail, the envelope 102 also has a rectangular prismatic shape: the front wall 104a and the rear wall 104b (with a square or rectangular shape) are facing and parallel to each other and connected to each other by means of the first and second side walls 104c , 104d (with a square or rectangular shape) also facing and parallel to each other. In the closed condition.

- the front walls 4a, 104a, respectively of the container and of the envelope, face each other directly,

- the rear walls 4b, 104b, respectively of the container and of the envelope, face directly one to the other,

- the first side walls 4c, 104c, respectively of the container and of the envelope, face directly one to the other,

- the second side walls 4b, 104d, respectively of the container and of the envelope, face directly one to the other.

However, the possibility of making a casing 102 having a different shape, for example with a trapezoidal section, is not excluded.

As can be seen for example from Figures 3, 5, 7 and 8, the casing 102 further comprises a top wall 109 having a rectangular shape and from which the side walls 104 and in particular the front wall 104a, the rear wall 104b and the first and second side parts 104c, 104d. The casing 102 therefore comprises a single access 105 defined in opposition to the top wall 109. However, the possibility of making a casing 102 having two or more accesses 105 is not excluded; for example, the casing 102 could have an access 105 on at least one of the side walls 104c, 104d of the casing 102 itself. The top wall 109 is configured to abut, in the closed condition, to the free edge 6 of the opening 5 to occlude the latter as shown in figure 6.

As mentioned above, the casing 102 is counter-shaped to the container 1. The counter-shaped configuration of the container 1 and the casing 102 allows the side walls of the casing 102 to slide (relatively) externally side by side with the side walls 4 of the container 1 during the transition from the condition closing to opening and vice versa. To allow this relative movement, the casing 102 has a slightly larger size than the container 1, sufficient to allow the latter to be inserted into the internal volume 103.

As can be seen from figures 9 and 10, the casing 102 comprises at least an external panel 10a and an internal panel 10b defining a housing seat 49 inside which a selector 90 is housed, which will be better described in the following detailed description. .

At least one side wall 10 of the casing 102, in particular at least one between the front wall 104a and the rear wall 140c, is defined by the external panel 10a. It is useful to note that the internal panel 10b is arranged, at least in the closed condition of the envelope 102 and of the container 1, in interposition between the container 1 and the external panel 10a to which it is joined in one piece at a folded edge 10c . The external and internal panels 10a, 10b face each other directly, presenting, in section, a substantially "V" shape whose concavity faces the top wall 109 of the casing 102. The external panel 10a and the internal panel 10b therefore they define a folded portion along the folded edge 10c, the latter defining at least part of said free edge 106 of the envelope 102.

The external panel 10b has at least one through opening 48 configured to allow, in the closed condition of the case 102 and of the container 1, to intervene from the outside of the container on the selector 90. The through opening 48 is therefore configured to place communication, at least in the closed condition of container and wrapper, the housing seat 49 and the environment outside the package 100.

The package 100 further comprises a safety device 11 comprising: - at least a first coupling portion 12 carried by the casing 102 and arranged at least in part in the internal volume 103,

- at least a second coupling portion 13 carried by the container 1 and arranged externally to the compartment 3.

The first and second coupling portions 12, 13 are configured to engage each other stably externally to the container 1, in the closed condition, to define a locking condition of the safety device 11 in which the first and second coupling portion 12, 13 prevent the container and wrapper from passing from the closed to the open condition.

The first hooking portion 12 is engaged to at least one side wall 104 of the casing 102 carrying the selector 90, in particular the first hooking portion can be defined on the internal panel 10b. The first hooking portion 12 can be emerging in the internal volume 103 in a direction entering the latter and comprising at least one tab 12a protruding from the side wall 104 to define an undercut delimited by at least one gripping edge 12b placed entirely in the internal volume 103 , distinct and spaced from the free edge 106 of the access 105. The gripping edge 12b of the tab 12a is inclined with respect to the free edge 106 of the access 105 optionally by an angle between 20 ° and 80 °, even more optionally by an angle between 30 ° and 70 °. In detail, the tab 12a extends along a plane and faces directly the side wall 104 of the casing which directly carries the tab 12a. The tab 12a can be inclined with respect to the side wall 104 directly carrying said tab by an angle of less than 40 °, optionally by an angle of between 1 ° and 30 °. Said angle being measured between the surface of the tongue 12a directly facing the side wall 104 of the casing 102 and the same side wall 104 of the casing 102 directly bearing (directly joined as a piece) said tongue 12a.

In the accompanying figures, a first hooking portion 12 (at least one tab 12a) has been shown directly joined in one piece to at least one side wall 104 by means of a bending edge to define a folded portion. In fact, the tab 12a is in one piece with a side wall 104 and folded with respect to the latter in such a way that the tab is at least partially overlapped and faces the side wall 104 to which said tab is directly connected (joined by piece). In this configuration, the folding edge joining the tab 12a and the side wall 104, defines at least part of the free edge 106 of the access 105. Even if the tab 12a is integrally joined to the side wall 104, only a part of it defines the undercut adapted to cooperate with the second hooking portion 13: the gripping edge 12b is always distinct and spaced from the free edge 106 of the access 105.

In fact, the at least one tab 12a of the first hooking portion faces directly the side wall 104 of the casing directly bearing said tab 12a: the tab 12a is entirely superimposed on said side wall 104 of the casing 102 directly joined in one piece to the tongue, and spaced from the free edge 106.

On the other hand, the gripping edge 12b of each first hooking portion 12 is arranged in interposition between the top wall 109 and the access 105 of the casing 102. The gripping edges 12b face the side wall 104 of the casing 102 bearing directly (directly joined together) the tab 12a, spaced both from the free edge 106 and from the top wall 109.

As mentioned above, the safety device 11 can comprise at least a first coupling portion 12. In detail, the safety device 11 can comprise at least one of:

- at least one of said first coupling portion 12 carried by the front wall 104a of the casing 102,

- at least one of said first coupling portion 12 carried by the rear wall 104b of the casing 102,

- at least one of said first coupling portion 12 carried by the first side wall 104c of the casing 102,

- at least one of said first coupling portion 12 carried by the second side wall 104c of the casing 102.

In the accompanying figures, a non-limiting configuration of the invention has been illustrated in which the safety device 11 comprises a first coupling portion 12 carried by the front wall 104a and at least a respective first coupling portion 12 carried by the rear wall 104b: said first portions hooks 12 are placed in opposition to each other. Obviously, the possibility of providing two or more first hooking portions on the same side wall and / or at least one first hooking portion for each side wall 104 of the casing 102 is not excluded.

As mentioned above, the safety device 11 also comprises at least a second coupling portion 13. In particular, the safety device 11 could comprise only one second coupling portion 13 configured to cooperate with one or more of said first coupling portions 12 Alternatively, the safety device 11 can comprise a second hooking portion 13 for each first hooking portion 12 (non-limiting configuration illustrated in the accompanying figures).

The second coupling portion 13 is engaged with at least one side wall 4 of the container 1 and emerges from the latter in a direction outgoing with respect to the compartment 3. The second coupling portion 13 comprises at least one panel 13a protruding from the side wall 4 to define an undercut delimited by at least one gripping edge 13b placed externally to the compartment 3, distinct and spaced from the free edge 6 of the opening 5. The panel 13a has a substantially triangular or substantially trapezoidal or substantially "V" or "C" shape: in which the gripping edge 13b has at least one section, optionally two straight sections, inclined with respect to the free edge 6 of the opening 5, optionally by an angle comprised between 20 ° and 80 °, even more optionally by an angle comprised between 30 ° and 70 °. In greater detail, the free edge 13b of the panel 13a has a substantially "V" or "C" shape whose concavity faces the free edge 6 of the container. In detail, the panel 13a extends along a plane and faces directly the side wall 4 of the container 1 carrying the panel 13a directly; the panel 13a can be inclined with respect to the side wall 4 directly bearing said panel 13a by an angle of less than 40 °, optionally by an angle of between 1 ° and 30 °. The angle being measured between the surface of the panel 13a directly facing the side wall 4 and the same side wall 4 of the container 1 directly bearing (directly joined as a piece) said panel 13a.

The second coupling portion 13 is defined directly on the side wall 4: the second coupling portion forms at least part of the side wall 4. In detail, the panel 13a is obtained by means of the through cut of the side wall 4 so that on the it is possible to extract the panel 13a protruding with respect to said side wall as illustrated in Figure 4A. In this configuration, the panel 13 can extend from the side wall 4, spaced from the free edge 6, moving away from the latter by an angle of less than 40 °, optionally between 1 ° and 30 °, with respect to the side wall 4 from which the same panel 13a was obtained.

Each second coupling portion 13 comprises one and only one panel 13a having a substantially triangular or in any case pointed shape suitable for cooperating with the first coupling portion 12.

The safety device 11 can comprise at least a second hooking portion 13. In detail, the safety device 11 can comprise at least one of:

- at least one of said second coupling portion 13 carried by the front wall 4a of the container 1,

- at least one of said second coupling portion 13 carried by the rear wall 4b of the container 1,

- at least one of said second coupling portion 13 carried by the first side wall 4c container 1,

- at least one of said second coupling portion 13 carried by the second side wall 4c of the container 1.

In the accompanying figures, a non-limiting configuration of the invention has been illustrated in which the safety device 11 comprises a second coupling portion 13 carried by the front wall 4a and a respective second coupling portion 13 carried by the rear wall 4b: said second coupling portions coupling 13 are placed in opposition to each other.

In an exemplary but non-limiting embodiment of the container 1, the panel 13a can comprise, as shown in Figure 9, at least two portions 13a 'and 13a ", in which each of said portions 13a' and 13a" is configured to engage respectively with one of said tab 12a to define the locking condition of the container 1 and of the casing 102. The portions 13a 'and 13a "also have a substantially triangular or substantially trapezoidal shape). The gripping edge of each of said portions 13a ', 13a' 'defines a gripping edge having a substantially "V" shape whose concavity faces the free edge 6 of the opening 5.

The portion 13a 'is also spaced apart and adjacent to the portion 13a ": the portions 13a' and 13a" are side by side and directly facing an unlocking portion 17 of the casing 102 which will be detailed in the continuation of the description.

Obviously, the possibility of providing two or more second coupling portions distinct and spaced apart, located on the same side wall and / or at least a first coupling portion for each side wall 4 of the container, is not excluded.

In the configuration illustrated in the accompanying figures, the second coupling portion 13 carried by the front wall 4a of the container 1 is configured to cooperate, in the closed condition, with the first coupling portion 12 carried by the front wall 104a of the casing while the second portion coupling 13 carried by the rear wall 4b of the container 1 is configured to cooperate, in the closed condition, with the first coupling portion 12 carried by the rear wall 104b of the enclosure.

In the closed condition, the undercut defined by the panel 13a of the second hooking portion 13 is stably engaged to the undercut of the tab 12a of the first hooking portion 12 to define said locking condition. In the locked condition, the safety device prevents the casing and container from passing from the closed to the open condition. In fact, thanks to the presence of the first and second hooking portions, the safety device 11 keeps the package stably in the closed condition, preventing access from the outside to the products housed in the container 1.

Figure 9 schematically illustrates the engagement between the first and second coupling portions 12, 13 (locking condition of the safety device 11); as can be seen, in the locked condition, the second coupling portion 13 is interposed between the first coupling portion 12 and the side wall 104 of the casing 102, carrying said first coupling portion, to define an undercut suitable for limiting the movement in separation between the casing 102 and the container 1 so as to prevent the passage from the closed to the open condition.

As mentioned above, the panel 13a has a substantially "V" shape, the pointed portion of which faces away from the free edge 6. The pointed (extremal) portion of the "V" is configured to define an opening portion adapted to facilitate engagement with the first coupling portion 12.

As mentioned above, the package 100 comprises at least a selector 90 in sheet material, optionally paper, carried by at least one between the container 1 and the envelope 102 and movable at least between a first and a second operating position.

In the first operative position, the selector 90 allows, upon the occurrence of the closed condition of container 1 and casing 102, the first and second coupling portion 12, 13 to engage stably with each other to define a locking condition of the safety device 11 in the which said first and second hooking portions 12, 13 prevent the wrapper and container from passing from the closed to the open condition. Vice versa, in the second operative position the selector 90 prevents, upon the occurrence of the closed condition of container 1 and casing 102, the engagement between the first and second coupling portion 12, 13 so that casing and container can pass freely from the closed to open condition.

It is useful to note that the selector 90 is arranged, during the movement between the first and the second operative position, inside the internal volume of the casing 102. The selector 90 is engaged at least in part and stably carried by at least one side wall of the casing 102. In detail, the selector 90 is entirely engaged inside the housing seat 49, thus lying in interposition between the external panel 10a and the internal panel 10b.

The selector 90 comprises a maneuvering portion 91 directly facing the through opening 48 of the casing and configured to allow a user, at least during the closed condition of the container and casing, to contact the gripping portion from the outside of the package and to move the selector between the first and second operating position, and vice versa. During this movement, which takes place inside the internal volume of the casing, the selector 90 translates while maintaining substantially the same distance from the top wall 109 of the casing, along a direction substantially parallel to the plane of lying of the external panel 10a of the casing 102 , in particular substantially parallel to the fold edges 10c of the outer and inner panel 10a, 10b. Finally, it is useful to note that the selector 90, during the movement between the first and the second operating position, is configured to push the second coupling portion 13 towards the compartment 3 of the container 1, allowing the wrapping and the magazine to pass through closed to open condition. The selector 90, in the second operative position, acts in thrust on the second coupling portion in interposition between the first and the second coupling portion 12, 13. In said position, the selector 90 prevents, following at least partial introduction of the container 1 inside the internal volume of the casing 102, the engagement between the first and the second coupling portion 12, 13 and consequently the occurrence of the locking condition of the safety device 11.

The package 100 can also comprise a further safety device in turn comprising a first and a second hooking portion 12, 13 in accordance with what has been previously described. As shown in Figures 5 and 6, the further safety device can comprise at least one release portion 17 configured to define at least one through access 18 on at least one side wall 104 of the casing 102, in correspondence with the first and second coupling portions 12, 13: the release portion 17 is configured to allow, at least in the locking condition of the safety device 11, direct access from the outside of the package to at least one of said first and second coupling portions 12, 13 to allow disengagement and therefore allowing the wrapper 102 and container to pass from the closed to the open condition.

In detail, the release portion 17 is configured to allow a user, at least in the locking condition of the safety device 11, to intervene from the outside of the package 100 directly on at least one of said first and second hooking portions 12, 13 manually and / or by means of an opening device which can be inserted through the through access 18 which can be defined by said release portion. In still greater detail, the release portion 17 is configured to allow, at least in the locking condition of the safety device 11, to intervene from the outside of the package 100 directly on the panel 13a of at least one of said second coupling portions 13. Not however, the possibility is excluded that, in an embodiment of the present container 1, each of the portions 13a 'and 13a "faces respectively a first and a second release portion 17a, 17b, in which said first and second release portion 17a, 17b are adjacent and spaced apart.

The release portion 17 can comprise, but is not limited to, a through access 18 defined on at least one side wall 104 of the casing 102: the through access 18 is configured to allow communication between the external environment and the internal volume 103 and in the Specifically, it allows a user to reach the panel 13a, optionally the portions 13a 'and 13a ", of the second release portion 17 in the locking condition of the safety device 11 and therefore in the closed condition of the casing and container. The through access 18 of the release portion 17 has an open perimeter profile: the through access 18 is joined in one piece to the free edge 106 of the access 105 and essentially defines a recess of said free edge 106.

Alternatively, the release portion 17 could comprise a deformable portion placed, in the locking condition, in front of the first and second coupling portions 12, 13: in this configuration, the release portion 17 essentially comprises a thrust portion configured to be moved (manually by the user or by means of an opening device) between a thrust condition and a rest condition. In the rest condition, the thrust portion is spaced from the safety device, while in the thrust condition the thrust portion operates on the safety device to allow the disengagement between the first and the second coupling portion 12, 13 and consequently the passage of casing and container from closed to open condition. In the thrust condition, the thrust portion contacts the second coupling portion 13 and allows its disengagement with respect to the first coupling portion 12. In fact, the thrust portion can functionally act as a button. The thrust of a finger of a user on the thrust portion in a direction entering the package allows the thrust portion to come into contact with the second coupling portion 13, disengaging it from the undercut of the first coupling portion 12. The thrust portion can be reversibly movable between the thrust condition and the rest condition. For this purpose, the thrust portion can be elastically deformable between the thrust condition and the rest condition.

The release portion 17, optionally the through access 18, is defined in interposition between the two tabs of the first coupling portion 12: the two tabs 12a are positioned symmetrically with respect to the release portion 17. Always in the locked condition, the second coupling portion 13, optionally the panel of the second coupling portion 13, is interposed between the release portion 17 and the first coupling portion 12. The release portion (optionally through access 18) allows the user - by means of a direct manual action or by inserting an opening device - to push the panel 13a of the second coupling portion 13 against the side wall 4 of the container carrying said portion in such a way as to cause disengagement with the at least one tab 12a of the first hooking portion 12. The opening device can be part of the package 100.

Implementation process

The present invention also relates to a process for manufacturing a package 100 in accordance with one or more of the attached claims and / or in accordance with the above description.

The method provides for the preparation of the envelope 102 which can be made by means of a first flat blank 50 made of sheet material, optionally paper. The first blank 50 includes:

- a central sheet 51,

- a predetermined number of lateral sheets 52 joined in one piece to the central sheet 51 and emerging therefrom starting from a perimeter edge,

- at least one peripheral sheet 53 engaged to at least one of said side sheets 52. The central sheet 51 has a polygonal shape, optionally rectangular or square. From each side of the central sheet 51 extends a side sheet 52 which also has a polygonal shape, optionally rectangular or square.

The preparation of the envelope 102 comprises the sub-step of folding the predetermined number of side sheets 52 to define the predetermined number of side walls 104 of the envelope 102. In detail, the side sheets are folded with respect to the central sheet 51 in such a way that from the flat blank it is possible to obtain an envelope having a three-dimensional conformation. The lateral sheets 52 are bound together in such a way that the envelope 102 can maintain its three-dimensional shape; the side sheets 52 can be bound directly to each other by glue or any adhesive material. Alternatively, the blank 50 can be provided with at least one connecting sheet 55 which integrally joins two adjacent side sheets 52 (Figure 2); in this configuration, the process - simultaneously with the folding of the side sheets 52 - provides for the overlapping and joining, for example by gluing, of the connecting sheet 55 to adjacent folded side sheets: in this way, the envelope can maintain its three-dimensional shape with the side sheets 52 defining the side walls 104 and the central sheet defining the top wall 109.

The method further provides for the definition of the at least one first hooking portion 12 by means of the at least one peripheral sheet 53. In detail, the peripheral sheet 53 is integrally joined to at least one side sheet 52 of the first blank 50; the peripheral sheet 53 of the first blank 50 emerges from a perimeter edge of at least one side sheet 52 of the first blank 50 itself on the opposite side to the central sheet 51 of the first blank. In the accompanying figures, a first blank 50 comprising two opposite peripheral sheets 53 has been illustrated in a non-limiting way. The possibility of providing one or more peripheral sheets joined together and emerging from each side sheet 52 is not excluded.

The first hooking portion 12 is made by folding the peripheral sheet 53 of the first blank 50 above the side sheet 52 of the same first blank 50 to which said peripheral sheet 53 is joined in one piece. Following the folding of the peripheral sheet, at least a part of it is bound, for example by gluing, to a part of the side sheet to which it is directly joined in one piece (directly to the side wall 104). The folding of the at least one peripheral sheet 53 can be performed previously, simultaneously or after the folding and binding of the side sheets 52. In one embodiment, the peripheral sheets are folded before the folding of the side sheets; only following the folding of the peripheral sheets, the method provides for the folding and constraint of the side sheets in such a way that, simultaneously with the definition of the side walls 104, the definition of the first coupling portion 12 is obtained.

As can be seen from Figure 1A, each peripheral sheet 53 can comprise a first and a second portion 53a, 53b spaced apart, side by side and engaged with the same side sheet 52; the first and second portions 53a, 53b of said peripheral sheet 53 are configured to define - following the folding of the peripheral sheet and of the side sheets 52 - the side-by-side tabs 12a of the first coupling portion 12.

The central sheet 51, the side sheets 52 and the peripheral sheets 53 of the first blank 50 can be joined in one piece to define a single blank in a single piece, for example at least partially in paper material. The envelope 102 can therefore be obtained by folding and gluing steps of a single blank sheet (first blank 50 flat). The first blank can be obtained by means of one or more punching steps of a single precursor sheet.

As described above, the casing 102 also carries the release portion 17 which can be obtained by providing a notch 56 of at least one side sheet 52 of the first blank 50: the notch 56 is of the type passing through the side wall 52 and is made on the side wall 52 carrying the peripheral sheet 53. In particular, the notch 56 is made in correspondence with the peripheral sheet 53 and in particular in interposition between the first and second portions 53a, 53b of each peripheral sheet 53. The notch 56 can have an open profile as illustrated in Figure 2 so that it can define the through access 18; alternatively the notch 56 can be an open portion adapted to define the thrust portion as described above. The method provides for the preparation of the container 1 which can be made by means of a second flat blank 70 made of sheet material, optionally paper. The first blank 70 includes:

- a central sheet 71,

- a predetermined number of side sheets 72 joined in one piece to the central sheet 71 and emerging therefrom starting from a perimeter edge,

The central sheet 71 has a polygonal shape, optionally rectangular or square. From each side of the central sheet 71 extends a side sheet 72 also having a polygonal shape, optionally rectangular or square. The container arrangement 1 comprises the sub-step of folding the predetermined number of side sheets 72 to define the predetermined number of side walls 4 of the container 1. In detail, the side sheets 72 are folded with respect to the central sheet 71 so that from flat blank 70, a container 1 having a three-dimensional conformation can be obtained. The lateral sheets 72 are linked together in such a way that the container 1 can maintain its three-dimensional shape; the side sheets 72 can be bound directly to each other by means of glue or any adhesive material. Alternatively, the blank 70 can be provided with at least one connecting sheet 75 which integrally joins two adjacent side sheets 72 (Figure 1); in this configuration, the process - simultaneously with the folding of the side sheets 72 - provides for the overlapping and joining, for example by gluing, of the connecting sheet 75 to adjacent folded side sheets 72: in this way, the container 1 can maintain the its three-dimensional shape with the side sheets 72 defining the side walls 4 and the central sheet 71 defining the bottom wall 9.

The method further provides for the definition of the at least one second hooking portion 13. Each second hooking portion 13 can be performed by means of the following steps of preparing a peripheral sheet 73 joined in one piece to at least one of said side sheets 72 of the second blank 70, said peripheral sheet 73 of the second blank 70 emerging from a perimeter edge of at least one side sheet 72 of the second blank 70 itself on the opposite side to the central sheet 71 of the second blank.

Subsequently, the peripheral sheet 73 is folded over the side sheet 72 of the same second blank 70 to which said peripheral sheet 73 is joined in one piece; following the folding, the peripheral sheet 73 is at least partially superimposed and facing the side sheet 72 to which it is directly joined in one piece. Following the folding of the peripheral sheet 73, at least one part of it is bound, for example by gluing, to a part of the side sheet 72 to which it is joined directly in one piece (directly to the side wall 4). The folding of the at least one peripheral sheet 73 can be performed previously, simultaneously or subsequently, the folding and binding of the side sheets 72. In one embodiment, the peripheral sheets 73 are folded before the folding of the side sheets 72; only following the folding of the peripheral sheets 73, the procedure provides for the folding and constraint of the side sheets 72 in such a way that, simultaneously with the definition of the side walls 4, the definition of the second coupling portion 13 is obtained. Alternatively, the second coupling portion 13 can be obtained by means of a step of cutting one of said side sheets 72 of the second blank 70 to define directly on said side sheet at least one through notch 76 able to define the panel 13a of the second coupling portion 13.

Figure 1B illustrates a second blank 70 presenting, on one side, a peripheral sheet 73 emerging from a side sheet 72 and, on the opposite side, a notch 76 able to define, on the side sheet 72, the panel 13a of the second coupling portion 13. The central sheet 71, the side sheets 72 and the possible peripheral sheet 73 (if present) of the second blank 70 can be joined in one piece to define a single blank in a single piece, for example at least partially in paper material. The container 1 can therefore be obtained through steps of folding and gluing a single blank sheet (first blank 70 flat). The second blank 70 can be obtained by means of one or more punching steps of a single precursor sheet.

The first and second blanks 50, 70 - although obtainable by means of a punching step of a single sheet - are distinct and separate pieces that can be processed separately to obtain a wrapper 102 separate from the container 1.

Closing method

The present invention also relates to a method of closing a package 100 in accordance with one or more of the attached claims and / or in accordance with the above description.

The method comprises a first step of positioning the wrapper 102 outside the container 1 so that the latter can be at least partially housed in the internal volume of the wrapper 102. Previously, the step of positioning the wrapper 102 outside the container 1 - said casing and container are completely separate and distinct from each other.

Subsequently, envelope 102 and container 1 are moved relatively with respect to each other so as to define the closed condition. The relative movement of the wrapper and container in the closed condition allows the first coupling portion 12 to be brought into correspondence with the second coupling portion 13 where the two portions can engage with each other. The relative movement provides for the relative translation of the casing 102 outside the container 1 with the side walls 104 of the casing 102 closely facing the side walls 4 of the container 1. The relative movement provides for the relative translation of the casing 102 with respect to the container 1 up to to an end-of-stroke position in which the top wall 109 of the casing 102 abuts the free edge 6 of the container 1 (Figure 6); in the end-of-stroke position, the free edge 106 of the casing 102 is arranged in correspondence with the bottom wall 9 of the container 1. In the end-of-stroke position the free edge 6 of the container rests on the top wall 109 of the casing 102 and prevents a further relative approach between the bottom wall 9 of the container 1 and the top wall of the casing 102. In the end-of-stroke position, the first hooking portion 12 faces the second hooking portion 13 of the container 1 and is ready to receive the latter as a commitment.

In fact, once these portions (12, 13) correspond to each other (for example in the end-of-stroke position), engagement of the first and second coupling portion 12, 13 of the locking device is obtained. safety 11 to define the locking condition. By relative movement of the envelope with respect to the container is meant the movement of both parts, i.e. envelope and container, or the movement of only one of said parts (only the envelope 102 or only the container), keeping the other of the two parts (keeping the casing 102 or the container fixed) in such a way that a relative motion is defined between these (casing and container).

Opening method

The present invention also relates to a method of opening a package 100 in accordance with one or more of the attached claims and / or in accordance with the above description.

Previously carrying out the method of opening the package 100, the latter is in the locking condition of the safety device. The opening method comprises a step of contact, from the outside of the package 100, of at least one of the first and the second hooking portion 12, 13 through the release portion 17. The contact can be direct through or it can take place indirectly to for example by means of the thrust portion of the casing 102. For example, the step of contacting at least one of the first and the second coupling portion 12, 13 comprises at least one of the following sub-steps:

- insert at least one opening device through the through access 18 of the release portion 17,

- manually and directly contacting at least one of the first and second coupling portions 12, 13, for example by inserting a finger of a user through the through access 18 of the release portion 17, - deforming a thrust portion thereof casing 102 so that said thrust portion can contact at least one of the first and second coupling portion 12, 13.

Subsequently, the opening method provides for a disengagement step of the first and second coupling portion 12, 13. The disengagement step comprises pushing the second portion of the container 1 towards the compartment 3 (figure 7), optionally by means of a manual intervention of a user (directly on the second portion 13 or indirectly by means of the elastic deformation of the thrust portion) or by means of an opening device.

Following the disengagement of the first and second coupling portions 12, 13, the opening method provides for a phase of relative movement away from the container 1 and casing 102 (condition illustrated in Figures 8 and 10) until the opening condition of the Casing 102. The relative movement can be obtained by moving both the container and the casing or it can be performed by keeping one of said container and casing stationary and moving only the other between said container and casing.
