DETAILED DESCRIPTION

Container 1

[0118] The reference 1 indicates a container suitable for housing various products, such as medicines, cosmetics, cleaning products (laundry and dishwashing detergents), food and tobacco products.

[0119] As may be seen in FIG. 1, container 1 includes a storage 2 made of sheet material, e.g., paper material, defining a compartment 3 for housing products. The storage 2 has at least one side wall defining at least one passage opening 5 delimited by a free edge 6. The storage 2 may have a substantially prismatic shape, e.g., rectangular prismatic as illustrated for example in the attached figures, although the possibility of making a storage 2 with a different shape, e.g., having a square, trapezium shape or cylindrical shape, is not excluded. The free edge 6 substantially defines an upper section of the storage 2, which lies substantially on one plane.

[0120] The storage 2 may include 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 by a first and a second side wall 4c, 4d, also facing and parallel to each other. The front wall 4a is spaced and opposite to the rear wall 4b; The first and second side walls 4c, 4d are also spaced and opposed to each other. The front, rear and side walls (4a, 4b, 4c, 4d) define the passage opening 5, delimited by the free edge 6.

[0121] The storage 2 also includes a bottom wall 4f from which the front wall 4a, the rear wall 4b and the first and second side parts 4c, 4d emerge, starting from a perimeter edge. The storage 2 may therefore include a single passage opening 5 opposite to the bottom wall 4f. In detail, the front wall 4a, the rear wall 4b, the first side wall 4c and the second side wall 4d, in cooperation with the bottom wall 4f, delimit the compartment 3.

[0122] The storage 2 may be obtained by means of a process of folding and gluing a flat blank made of sheet material, e.g., paper material; said process involves providing of a side wall where a glued overlapping area is defined that allows the storage to maintain a three-dimensional shape, wherein the side wall (e.g., walls 4a-4d) emerges from the bottom wall 4f.

[0123] The distance between the free edge and the bottom wall determines the extension of the side walls of the storage: this extension basically defines the height of the storage 2 which may be, in a non-limiting way, more than 50 mm, optionally more than 70 mm, even more optionally between 80 mm and 150 mm. The compartment 3 may have a volume of more than 40 cm.sup.3, optionally more than 100 cm.sup.3 depending on the products to be housed. For example, if container 1 is used to house medium-sized products, the compartment 3 may have a volume between 800 and 1,400 cm.sup.3. For large products, the volume of the compartment 3 may reach 10,000 cm.sup.3.

[0124] One or more side walls of the storage 2 may comprise at least one flat sheet emerging from the bottom wall 4f and delimiting at least part of the compartment 3. In particular, each side wall may consist of a single sheet of paper material. In detail, the storage 2 may be substantially identical to the container of the package as described in the PCT patent application No. WO 2021/044266 A1 as published, from page 14, line 26, to page 15, line 7. Alternatively, at least one side wall of the storage 2 may include at least one outer panel 41 and at least one inner panel 42 facing and stably engaged to each other. In detail, the storage 2 may be substantially identical to the storage of the container as described in the Italian Patent Application 102021000025892, from page 16, line 13, to page 17, line 24, which is incorporated by reference and corresponds to US 2023/113321.

[0125] In detail, at least one side wall of the storage 2 may include an outer panel 41 and an inner panel 42 facing and engaged each other, or at least partially overlapping each other. The outer panel 41 and the inner panel 42 may be joined together at a folding edge to define a folded portion; for example, the folding edge may define at least one section of the free edge 6 of the storage 2. In fact, the outer panel 41 and the inner panel 42 lie on their respective planes substantially parallel and are fixed to each other, for example by means of glue: the outer panel 41 defines at least part of an external surface of the storage 2, optionally delimiting a part of the compartment 3, whereas the inner panel 42 defines at least a part of an internal surface of the storage 2, optionally delimiting at least part of the compartment 3. As may be seen in FIGS. 5-8, the inner panel 42 may have a smaller surface extension than the surface extension of the outer panel 41; for example, the inner panel 42 may be overlapped only on a portion of the top of the outer panel 41 and may, in a non-limiting way, cover only 5% to 40%, optionally 7% to 30%, of the surface extension of the outer panel 41.

[0126] For example, at least one of the front wall 4a and the rear wall 4b of the storage 2 may be defined by said outer and inner panel 41, 42. The following figures illustrate, in a non-limiting way, a configuration of the storage 2 wherein both the front wall 4a and the rear wall 4b are defined by the said outer panel 41 and inner panel 42; the first and second side walls 4c, 4d may be defined by a single panel (single sheet) that delimits at least part of the external and internal surface of the storage 2.

[0127] The container 1 includes a closure system 7 made of sheet material, optionally paper material, configured to define a lid. In detail, the closure system 7 is movable with respect to the storage 2 at least between: [0128] a closure condition where the closure system 7 prevents communication between the compartment 3 of the storage 2 and the external environment (FIG. 3), [0129] an open condition where the closure system 7 allows communication between the compartment 3 and the external environment.

[0130] The closure system 7 and the storage 2 may be distinct and completely separable elements and therefore mobile with respect to each other at least between: [0131] the closure condition where the closure system 7 occludes the passage opening 5 of the storage 2, and [0132] the open condition where the closure system 7 is separated from the storage 2 and allows the communication between the compartment 3 and the external environment.

[0133] The closure system 7 comprises a predetermined number of side walls defining at least one access delimited by a free edge 7b configured to allow the passage of the storage 2. The predetermined number of side walls of the closure system 7 emerges from a top wall 7a which delimits, in cooperation with said side walls, an internal volume 7f configured to receive at least part of the storage 2 (e.g., at least 50% of the side wall of the storage); in fact, the access is configured to connect the internal volume 7f with the external environment, as well as to allow the insertion and removal of the storage 2 in/from the internal volume 7f.

[0134] The storage 2, in the closure condition (FIG. 3), is arranged in the internal volume 7f: the closure system 7, in said condition, prevents the insertion and removal of products from the storage 2. During switching from the closure condition to the open condition, and vice versa, the storage 2 and the closure system 7 slide relatively close to each other in approach or away from each other: during said relative movement, the storage 2 is placed at least in part in the closure system 7 and moves relatively (due to the movement of at least one of these storages and the closure system) in such a way that the bottom wall 4f of the storage 2 and the top walls 7a of the closure system 7 move closer or farther away from each other.

[0135] The closure system 7 has a structure that is at least partially countershaped to the storage 2 in such a way that, in the closure condition, the closure system 7 is fitted on the outside of the storage 2. In detail, the closure system 7 includes a front wall 8a and a rear wall 8b opposite to each other and connected by a first and a second side wall 8c and 8d, also spaced and opposite to each other. In detail, the closure system 7 also has a rectangular prismatic shape: the front wall 8a and the rear wall 8b (square or rectangular) are facing and parallel to each other and connected to each other by means of the first and second side walls 8c,8d (square or rectangular) which are also facing and parallel to each other. In the closure condition: [0136] the front walls 4a and 8a of the storage 2 and the closure system 7 respectively directly face each other, [0137] the rear walls 4b, 8b, respectively of the storage 2 and the closure system 7 respectively directly face each other, [0138] the first side walls 4c, 8c, respectively of the storage 2 and the closure system 7, respectively directly face each other, [0139] the second side walls 4d, 8d, respectively of the storage 2 and the closure system 7, respectively directly face each other.

[0140] However, the possibility of creating a closure system 7 with a different shape, for example with a trapezoidal section, is not excluded.

[0141] The closure system 7 comprises the top wall 7a from which the front wall 8a, the rear wall 8b and the first and second side parts 8c, 8d emerge from a perimeter edge of the top wall 7a. The closure system 7 therefore comprises a single access defined in opposition to the top wall 7a and delimited by the free edge 7b.

[0142] The counter-shaped configuration of the storage 2 and the closure system 7 allows the side walls of the closure system 7 to slide (relatively) externally side by side with the side walls of the storage 2 during switching from the closure to the open condition, and vice versa. To allow said relative movement, the closure system 7 has a slightly larger size than the storage 2, sufficient to allow the latter to be inserted into the internal volume 7f.

[0143] Alternatively, in an alternative embodiment not shown in the following figures, the closure system 7 may be engaged at the free edge 6 of the storage and may be rotated relative to the latter between the open and closure conditions, and vice versa. Also in the latter embodiment, the closure system 7 includes a predetermined number of side walls defining at least one access delimited by a free edge 7b configured to allow the insertion of the storage 2. The predetermined number of side walls of the closure system 7 may be defined by a front wall 8a that connects a first and a second side wall 8c, 8d facing each other; the predetermined number of side walls emerges from a top wall 7a which, in cooperation with said side walls, delimit the internal volume of the closure system 7 configured to receive at least part of the storage 2. The closure system may then be hinged to a section of the free edge 6 of storage 2 by means of the top wall 7a; relative movement by rotation between closure system 7 and storage 2 may be obtained by moving (in particular rotating) both parts, i.e., both closure system 7 and storage 2, or it may be achieved by moving only one of the parts.

[0144] At least one side wall of the closure system 7optionally the front wall 8a, the rear wall 8b, the first side wall 8c and the second side wall 8demerge from the top wall 7a, optionally from an outer perimeter edge of the top wall, for a predetermined extension: this extension essentially defines the height of the closure system 7 which may be, in a non-limiting way, greater than 30 mm, optionally between 35 mm and 70 mm. In detail, the height of the closure system 7 may be equal to or lower than the height of the storage 2. As shown in FIG. 3, in the closure condition, the free edge 6 of the storage 2 may be placed in proximity, optionally in contact, with the top wall 7a of the closure system 7 while the free edge 7b of the closure system 7 is placed in proximity, optionally in contact, with the bottom wall 4f of the storage 2. The internal volume 7f of the closure system may be greater than 40 cm.sup.3, optionally higher than 100 cm.sup.3 depending on the size of the storage to be closed.

[0145] One or more side walls of the closure system 7 may comprise a single panel or flat sheet emerging from the top wall 7a, or it may comprise two or more panels at least partially overlapping. In detail, the closure system 7 may be substantially identical to the case of the package as described in the PCT patent application No. WO 2021/044266 A1 as published, from page 15, line 8, to page 16, line 17, which is incorporated by reference. Alternatively, at least one side wall of the closure system 7 may be substantially of the type described in the Italian patent application 102022000014821 from page 23, line 14, to page 27, line 17, which is incorporated by reference.

[0146] The closure system 7 may also be made by folding and gluing processes of a blank in flat sheet material, optionally paper, or it may take advantage of a slot/graft portion system as described above for the storage.

[0147] As mentioned above, the closure system may be hinged to the free edge of the storage 2. In addition, the closure system 7 may only comprise the top wall 7a hinged to the free edge of the storage 2 and a single side wall that emerges from the opposite side to the free edge 6, with respect to the top wall. The closure system 7, in the closure condition, may be configured to place the side wall outside the compartment 3 of the storage. Alternatively, the closure system 7, in the closure condition, may be configured to place at least part of the side wall (e.g., at least part of the side wall) in the compartment 3 of the storage (condition not shown).

[0148] The container 1 may include at least a first portion of coupling 12 carried by the closure system 7 and at least a second portion of coupling 13 carried by the storage 2 and configured to cooperate with the first portion of coupling 12; the first and second portion of coupling 12, 13 are configured to engage each other in the closure condition of the storage 2 and the closure system 7 to define a locking condition where the first and second coupling portions 12, 13 prevent the closure system 7 and the storage from switching from the closure to the open condition.

[0149] The first coupling portion 12 is carried by at least one side wall of the closure system 7.

[0150] In one embodiment, the first portion of coupling 12 is carried by the front wall 8a and the rear wall 8b of the closure system 7. Obviously, the possibility of providing one or more first coupling portions 12 on the same side wall and/or at least a first portion of hooking 12 for each side wall of the closure system 7 is not excluded.

[0151] The first coupling portion 12 is placed at least in part in the internal volume 7f of the closure system 7; the first coupling portion 12 is spaced from the free edge 7b of the closure system 7, optionally interposed to the top wall 7a and the free edge 7b. In detail, the first coupling portion 12 includes at least one tab 12a in sheet material, optionally paper material, configured to engage, in the closure condition of the closure system and the storage, the second coupling portion 13 to define said locking condition; tab 12a is delimited by a perimeter edge 12b placed entirely at the internal volume 7f, distinct and spaced from the free edge 7b, which is interposed to the top wall 7a and the free edge 7b of the closure system 7.

[0152] The tab 12 may be rectangular, square or trapezoidal in shape. The possibility of making a 12a tab with a different shape, e.g., semicircular, is not excluded. For example, the perimeter edge 12b of tab 12a may be, at least for one section, tilted to the free edge 7b of the access, optionally by an angle between 20? and 80?, even more optionally by an angle between 30? and 70?. For example, the perimeter edge 12b of the tab 12a of the first coupling portion 12 may have a C or V shape whose concavity faces the free edge 7b of the closure system 7.

[0153] In more detail, the first coupling portion 12 may be of the type described in the PCT patent application WO 2021/044266 A1 as published, from page 16, line 18, to page 17, line 35, and incorporated by reference. Alternatively, the first coupling portion 12 may be substantially of the type described in the Italian patent application No. 102022000014821 from page 27, line 18, to page 29, line 16 which is incorporated by reference. The closure system 7 may further comprise a spacer as described in the Italian patent application No. 102022000014821 from page 29, line 17, to page 31, line 2, wherein this Italian patent application is incorporated by reference.

[0154] As mentioned above, the container 1 includes at least a second coupling portion 13 configured to cooperate with one or more of the first coupling portions 12 to define the locking condition. In detail, the container 1 may include a second coupling portion 13 for each first coupling portion 12. The second coupling portion 13 is carried by at least one side wall of the storage 2 and emerges outside the compartment 3 of the storage 2, distinct and distanced from the free edge 6 of the latter. In fact, the first and second coupling portions, in the locking condition, are engaged externally the compartment 3 of the storage 2 and internally the internal volume 7f of the closure system 7.

[0155] The second coupling portion 13 may comprise at least one tab 13a protruding from the side wall of the storage, e.g., located outside the compartment 3. The tab 13a is delimited by a separate perimeter edge 13b spaced from the free edge 6 of the passage opening 5. The tab 13a may have a substantially rectangular or triangular or substantially trapezium shape or substantially V or C shape: wherein the perimeter edge 13b has at least one section, optionally two straight sections, tilted with respect to the free edge 6 of the passage opening of the storage, optionally by an angle between 200 and 80?, even more optionally by an angle between 30? and 70?. In more detail, the perimeter edge 13b of tab 13a may have a substantially V or C shape whose concavity faces the free edge 6 of the storage 2.

[0156] The tab 13a extends substantially along a plane and directly faces the side wall of storage 2 directly supporting tab 13a; the tab 13a may be tilted with respect to the side wall of the storage 2 directly carrying said tab 13a by an angle of less than 40?, optionally by an angle between 1? and 30?; the angle is measured between the surface of the tab 13a directly facing the side wall of the storage and the same side wall directly carrying (directly joined in a single piece to) said tab 13a. The second coupling portion 13 may be directly joined to at least one of the side walls of the storage 2 by means of a folding edge to define a folded portion. In this configuration, the tab 13a is in one piece with a side wall and folded with respect to the latter in such a way that the tab 13a at least partially overlapping and facing the side wall to which said tab 13a is directly connected (piece unit). Only a part of the tab 13a cooperates with the first coupling portion 12.

[0157] In fact, the second coupling portion 13 of the container 1 may be similar or identical to the second coupling portion carried by the container of the package as described in the PCT patent application No. WO 2021/044266 A1 as published from page 18, line 1, to page 20, line 15. Alternatively, the second coupling portion 13 may be identical to the second coupling portion carried by the storage as described in the Italian patent application No. 102021000025892, from page 21, line 23, to page 24, line 8, which is suitable for cooperating with a spacer also described in the Italian patent application No. 102021000025892 from page 24, line 9, on page 26, Line 5, wherein this Italian patent application is incorporated by reference and corresponds to US 2023/113321.

[0158] In detail, as described above, at least one side wall of the storage 2 on which the second coupling portion 13 is defined (e.g., on the front wall 4a and on the rear wall 4b) may be of the type including the outer panel 41. In this configuration, the second coupling portion 13, optionally tab 13a, is defined on the outer panel 41; the second coupling portion 13 protrudes from the outer panel 41 outside the compartment 3: the tab 13a emerges from panel 41 of the storage 2 and away from the free edge 6 of storage 2.

[0159] In even more detail, the tab 13a of the second coupling portion 13 protrudes from the outer panel 41 of the storage starting from an attachment portion 13c: the attachment portion 13c of the second coupling portion 13 is connected in a single piece to the storage 2. As may be seen, for example, in FIG. 1, the tab 13a of the second coupling portion extends from the attachment portion 13c to an opposite end portion 13d; the end portion 13d of tab 13a, at least in the locking condition, is spaced from the outer panel 41 of the storage 2.

[0160] The tab 13a of the second portion of coupling 13, in the locking condition of the container, is movable at least between: [0161] a first operating position where the end portion 13d is distanced from the outer panel 41 of the side wall of the storage 2 to allow the engagement of the tab 13a of the second coupling portion with the first coupling portion 12 to define said locking condition, [0162] a second operating position where the end portion 13d is placed at a distance from the outer panel 41 of the storage 2 that is less than the distance between said outer panel 41 and said end portion 13d when tab 13a is placed in the first operating position. The tab 13, in the second operating position, is configured to disengage the first coupling portion 12 and allow the closure system and the storage to switch from the closure to the open condition.

[0163] The tab 13a of the second coupling portion 13 is normally placed in the first operating position; the tab 13a of the second coupling portion 13 is configured to reach the second operating position only after the user has intervened by pushing the tab 13a closer to the outer panel 41 of the storage 2.

[0164] As may be seen from the attached figures, the tab 13a may be obtained by carving the outer panel 41; the notch is through the thickness of the panel 41 and distance from the free edge 6 in such a way as to define said second portion of the hook 13 distanced from the free edge 6 and emerging outside the compartment 3. The notch essentially defines a pocket 43 where the tab 13a is at least partially housed. The pocket 43 defines a recess for the tab 13a configured to prevent the tab itself, in the second operating position or when it is folded towards the compartment 3, from interfering with the outer panel 41; in fact, an undesirable interaction with the outer panel could block the tab 13a of the second coupling portion 13 in the second operating position, thus preventing it from returning to the first operating position, thus preventing its subsequent engagement with the first coupling portion 12.

[0165] In the following figures, a storage 2 has been shown, in a non-limiting way, where the front wall 4a and the rear wall 4b are defined by the outer panel 41 and the internal panel 42: on both the outer panels 41 of the front wall 4a and the rear wall 4b there is the second coupling portion 13, defined by cut-out of the outer panel 41.

[0166] The first and second coupling portions 12, 13 may be disengaged, for example, by means of a release portion 60 configured to define at least one through access 61 on at least one side wall of the closure system, at the first and second coupling portions 12, 13. The release portion 60 is configured to allow, at least in the locking condition, direct access from the outside of the container 1 to at least one of the said first and second coupling portions 12, 13 to allow its disengagement.

[0167] In detail, the release portion 60 is configured to allow a user, at least in the locking condition, to intervene from the outside of the container directly on at least one of the first and second coupling portions 12, 13 manually and/or by an opening device that may be inserted through the through access 61. In even more detail, the release portion 60 is configured to allow, at least in the locking condition, to intervene from the outside of the container in thrust directly on the tab 13a of the second coupling portion 13.

[0168] The release portion 60 may include, in a non-limiting way, a through access 61 defined on at least one side wall of the closure system 7. Alternatively, the release portion 60 may include a deformable portion (not shown in the attached figures) placed, in the locking condition, in front of the first and second coupling portions 12, 13: in this configuration, the release portion 60 essentially includes a thrust portion configured to be moved (manually by the user or by means of an opening device) between a push condition and a rest condition. In the rest condition, the thrust portion is distanced from the second coupling portion 13, while in the thrust condition the thrust portion operates on the second coupling portion 13 to allow it to be disengaged with the first coupling portion 12; in this latter configuration described, the thrust portion of the release portion 60 may functionally act as a button. The thrust of a user's finger on the thrust portion in a direction entering the container allows the thrust portion to come in contact with the second coupling portion 13, disengaging it from the first coupling portion 12. The thrust portion may be reversibly moveable between the thrust condition and the rest condition. For this purpose, the thrust portion may be elastically deformable between the thrust condition and the rest condition.

[0169] In other words, the release portion 60 allows the user to push on the tab 13a of the second coupling portion 13 to push the latter from the first to the second operating position, or to push said tab 13a towards the compartment 3 of the storage 2 in such a way as to disengage it from the tab 12a of the first coupling portion 12.

[0170] The container 1 may additionally comprise a support panel 20 carried by the storage 2. In detail, at least one support panel 20 is placed, at least in the locking condition, at least in part in the compartment 3 of the storage 2 and is configured to contact at least the side wall of the storage 2 directly supporting the second portion of coupling 13. In fact, the function of the support panel 20 is to contact the side wall of the storage carrying the second coupling portion to limit its deformation towards the central area of the container; as may be understood, in fact, during the pushing action on the tab 13a exerted by the user, the side wall directly supporting the second coupling portion 13 tends to deform towards an internal area of the storage 2. This deformation may also be unwanted triggered in the event that a child attempts to open the container by squeezing the side walls of the storage 2; in this condition, an excessive deformation of the side wall of the storage 2 directly carrying the second coupling portion 13 could lead to an undesirable disengagement of the tab 13a of the second portion of coupling 13 with the tab 12a of the first coupling portion 12.

[0171] The support panel 20 is configured to avoid such undesirable deformation that would lead to an undesirable opening of the container; in other words, the support panel 20, in the locking condition, is configured to limit the movement of the side wall of the storage (optionally of the front wall 4a and/or the rear wall 4b) directly carrying the second coupling portion 13, away from the closure system, optionally facing at least one side wall of the storage directly carrying the second portion of coupling 13 (optionally of the front wall 4a and/or the rear wall 4b).

[0172] The support panel 20 is engaged, optionally hinged, to the free edge 6 of the storage; in detail, at least one support panel 20 is engaged to the section of the free edge section 6 of the storage 2 defined by at least one side wall of the storage immediately adjacent to the side wall directly supporting the second coupling portion 13. In the attached figures, the second coupling portion 13 is carried directly from the front wall 4a and from the rear wall 4b; In this configuration, at least one support panel 20 may be carried directly from at least one of the first and second side walls 4c, 4d of the storage 2; in particular, the support panel 20 is directly engaged to a section of the free edge 6 of the storage 2 defined by at least one of the first and second side walls 4c, 4d

[0173] As may be seen from the attached figures, at least one support panel 20 may include a first and a second support panel respectively engaged to the free edge section 6 respectively defined by the first and second side walls 4c, 4d of the storage 2; the first and second support panels, in the locking condition, substantially face each other.

[0174] From a structural point of view, each support panel is delimited by the following edges: [0175] an attachment edge 20a directly engaged to the storage 2, optionally hinged to free edge 6 of the storage 2, [0176] a distal edge 20b opposite to the attachment edge 20a, [0177] a first and a second lateral edge 20c, 20c opposite to each other which connect the attachment edge 20a and the distal edge 20d.

[0178] The distal edge 20d, in the locking condition, is placed in the compartment 3 of the storage 2; at least one section of at least one of the first and second lateral edge 20c, 20d of the support panel 20, in the locking condition, may be configured to contact at least one wall of the storage 2 directly supporting the second coupling portion 13, optionally respectively at least one of the front wall 4a and the rear wall 4b of the storage. In the configuration in which the second coupling portion 13 is defined on the outer panel 41 of the front wall 4a and on the outer panel 41 of the rear wall 4a, at least one section of at least one of the first and second lateral edges 20c, 20d of the support panel 20, in the locking condition, may be configured to contact the outer panel 41 and/or the inner panel 42 respectively of at least one of the front wall 4a and the rear wall 4b of the storage. In a non-limiting embodiment, at least one section of the first lateral edge 20c of the support panel 20, in the locking condition, is configured to contact at least one of the outer panel 41 and the inner panel 42 of the front wall 4a while at least one section of the second lateral edge 20d of the support panel 20, in the locking condition, it is configured to contact at least one of the outer panel 41 and the inner panel 42 of the rear wall 4b.

[0179] In fact, in the event that the side wall of the storage directly carrying the second coupling portion 13 is defined by the outer panel 41 and the internal panel 42, the support panel 20, in the condition of locking, may contact on one or both panels 41, 42 to limit, in the event of unwanted crushing of the wall, an undesirable deformation of the same.

[0180] As shown in the figures below, at least one support panel 20, optionally the first and second support panels, may include at least one protruding section configured to contact at least one side wall of the storage directly supporting the second portion of coupling 13; in detail, the first lateral edge 20c of each support panel 20 may comprise a protruding section 20c configured to contact the front wall 4a of the storage, optionally configured to rest against at least one of the outer panel 41 and the inner panel 42 of the front wall 4a, while the opposite second side edge 20d may comprise a respective protruding section 20d configured to contact the rear wall 4b of the storage, optionally configured to rest against at least one of the outer panel 41 and the inner panel 42 of the rear wall 4b.

[0181] From a dimensional point of view, at least one support panel 20 may have a width, defined by the maximum distance between the first and second lateral edge 20c, 20d, substantially identical to the distance between the front wall 4a and the rear wall 4b of the storage 2. This configuration may be used in the event that both the front part 4a and the rear wall 4b carry at least a second coupling portion; in this configuration, the width of the support panel allows it to come in contact with both walls (front and rear wall) to prevent/limit unwanted deformation during a storage crushing action. In other words, support panel 20, in such a configuration, would essentially define a cutsheet that contacts the front wall 4a and the rear wall 4b.

[0182] In fact, the support panel 20 is movable by rotation around the free edge 6 of storage 2 at least between: [0183] a first operating position where the support panel is placed outside the compartment 3 of the storage, and [0184] a second operating position where the support panel is folded in the compartment 3 of the storage.

[0185] In the locking condition of the container, the support panel is configured to remain in the compartment 3.

[0186] As may be seen from the combined figures, at least one side wall directly supporting the second coupling portion 13 may have at least one seat 30 configured to receive a portion of the support panel 20. For example, at least one of the frontal wall 4a and the rear wall 4b includes at least one seat 30. At least one seat 30 is delimited by a gripping edge 30a configured to engage, at least in the locking condition, the support panel 20; in fact, the gripping edge 30a is configured to engage, after the support panel 20 is folded in the compartment 3, said support panel 20, thus keeping it in the compartment 3.

[0187] The seat 30 may be defined on at least one of the outer panel 41 and the inner panel 42 of the front wall 4a and/or the rear wall 4b; on the other hand, the gripping edge 30a is configured to engage at least one section of at least one between the first lateral edge 20c and the second lateral edge 20d of the support panel 20.

[0188] FIGS. 5 and 6 show a storage 2 having a second coupling portion on the front wall 4a and the rear wall 4b which are defined by the outer panel 41 and the internal panel: the storage 2 also carries a first and a second support panel, respectively engaged at the free edge 6 of the storage defined by the first and second side wall 4c, 4d. In this configuration, both the outer panel 41 and the inner panel 42 of the front wall 4a and the rear wall 4b have two opposing seats 30; these seats 30 are defined on the free edge 6 of the storage (on the front wall 4a and on the rear wall 4b): the seats are substantially opposite to each other with respect to the second coupling portion 13. These seats 30 essentially define a recess of the free edge 6, capable of accommodating the protruding section of the support panel in support. In detail, the seats 30 defined on the front wall 4a are configured to support the protruding section 20c of the first lateral edge of the first and second panels; similarly, the seats 30 defined on the rear wall 4b are configured to support the protruding section 20d of the second lateral edge 20d of the first and second panels. In this configuration, during a crushing phase of the front wall 4a and/or rear wall 4b, the crushed side wall (optionally directly the internal panel 42) rests on the first and/or second section 20c, 20d of at least one of the support panels to prevent an unwanted deformation of the side wall capable of causing the unwanted disengagement of the first and second coupling portion 12, 13. It should be noted that, in this configuration, the protruding sections 20c, 20d do not prevent/limit the deformation of the side walls of the storage but essentially act as support portions that prevent the first and second panels from bending completely inside the compartment 3.

[0189] FIGS. 7 and 8 show a storage 2 having a second coupling portion 13 on the front wall 4a and the rear wall 4b which are defined by the outer panel 41 and the internal one: the storage 2 also carries a first and a second support panel, respectively engaged at the free edge 6 of the storage defined by the first and second side wall 4c, 4d. In this configuration, the seats 30 are defined only on the internal panel 42 and extend from the free edge 6 of the storage (on the front wall 4a and on the rear wall 4b): the seats 30 are substantially opposite to each other with respect to the second coupling portion 13. Said seats 30 essentially define a cut-out with an arched shape on the inner panel 42, capable of allowing the protruding section of the first and second support panels to pass through to allow that protruding section to contact the outer panel 41. In detail, the seats 30 defined on the front wall 4a are configured to allow the protruding section 20c of the first lateral edge 20c of the first and second panels to contact the outer panel 41 of the front wall 4a; Similarly, seats 30 defined on rear wall 4b are configured to enable the projecting section 20d of the second lateral edge 20d of the first and second panels to contact the outer panel 41 of the rear wall 4b. In this configuration, during a crushing phase of the front wall 4a and/or rear wall 4b, the outer panel 41 of the crushed side wall rests directly on the protruding section 20c, 20d of the first and/or second section 20c, 20d of at least one of the support panels to prevent an unwanted deformation of the side wall capable of causing the unwanted disengagement of the first and second coupling portions 12, 13. It should be noted that, in this configuration, it is directly the protruding sections 20c, 20d that contact the outer panel 41 and thus prevent/limit the deformation of the side walls of the storage.

[0190] FIGS. 9 and 10 show a storage 2 having a second portion of coupling 13 on the front wall 4a and the rear wall 4b which are defined by the outer panel 41 and the internal one: the storage 2 also carries a first and a second support panel, respectively engaged at the free edge 6 of the storage defined by the first and second side wall 4c, 4d. In this configuration, the seats 30 are defined only on the inner panel 42: in fact, a section of the perimeter edge of the inner panel 42 defines the gripping edge 30a of the seat: the gripping edges 30a defined on the inner panel 42 are substantially opposite each other with respect to the second coupling portion 13. In fact, in this configuration it is precisely the inner panel 42 that receives at least one support panel 20 to keep it in the second operating position. In detail, the support panel 20 extends in thickness between an upper surface 20 and a lower surface 20; The gripping edge 30a of the seat 30 defined by a section of the perimeter edge of the inner panel 42 is configured to directly contact the upper surface of the support panel 20, in particular a first and second side portion, to keep said panel 20 in the compartment 3 of the storage.

[0191] Additionally, the gripping edges 30a defined on the inner panel 42 of the front wall 4a are configured to allow the protruding section 20c of the first lateral edge 20c of the first and second panels to contact the outer panel 41 of the front wall 4a; Similarly, the gripping edges 30a defined on the inner panel 42 of the rear wall 4b are configured to allow the protruding section 20d of the second lateral edge 20d of the first and second panels to contact the outer panel 41 of the rear wall 4b. In this configuration, during a crushing phase of the front wall 4a and/or rear wall 4b, the outer panel 41 of the crushed side wall rests directly on the protruding section 20c, 20d of the first and/or second section 20c, 20d of at least one of the support panels to prevent an unwanted deformation of the side wall capable of causing the unwanted disengagement of the first and second coupling portions 12, 13. It should be noted that, in this configuration, it is directly the protruding sections 20c, 20d that contact the outer panel 41 and thus prevent/limit the deformation of the side walls of the storage.

[0192] FIGS. 11 and 12 show a storage 2 having a second coupling portion 13 on the front wall 4a and rear 4b which are defined by the outer panel 41 and inner panel 42: the storage 2 also carries a first and a second support panel, respectively engaged at the free edge 6 of the storage defined by the first and second side wall 4c, 4d. In this configuration, both the outer panel 41 and the inner panel 42 of the front wall 4a and the rear wall 4b have two opposing seats 30; these seats 30 are defined only on inner panel 42, at a distance from the free edge 6 of the storage (on the front wall 4a and rear 4b): the seats 30 are substantially opposite to each other with respect to the second coupling portion 13 and are delimited by a closed perimeter edge, optionally rectangular in shape. Said seats 30 essentially define a through-recess on the inner panel 42, capable of allowing the protruding section of the first and second support panels to pass through to allow that protruding section to contact the outer panel 41. In detail, the seats 30 defined on the front wall 4a are configured to allow the protruding section 20c of the first lateral edge 20c of the first and second panels to contact the outer panel 41 of the front wall 4a; similarly, seats 30 defined on rear wall 4b are configured to enable the projecting section 20d of the second lateral edge 20d of the first and second panels to contact the outer panel 41 of the rear wall 4b. In this configuration, during a crushing phase of the front wall 4a and/or rear wall 4b, the outer panel 41 of the crushed side wall rests directly on the protruding section 20c, 20d of the first and/or second section 20c, 20d of at least one of the support panels to prevent an unwanted deformation of the side wall capable of causing the unwanted disengagement of the first and second coupling portions 12, 13. It should be noted that, in this configuration, it is directly the protruding sections 20c, 20d that contact the outer panel 41 and thus prevent/limit the deformation of the side walls of the storage.

[0193] As may be seen, the support panel 20 also lies substantially on a plane, which may be tilted with respect to the plane of the free edge. As may be seen in FIGS. 7, 9 and 11, the position plane of the support panel 20 is tilted with respect to the position plane of the free edge 6 by an angle greater than 5?, optionally between 10? and 50?. In fact, in FIGS. 7, 9 and 11, the support panel 20 defines a descent entering the compartment of storage 2 which is in any case distanced from the bottom wall 4f of the storage. The support panel 20 in cooperation with storage free edge 6 defines the passage for products; in fact, the support panel reduces the cross-section of the products defined by the free edge 6. The presence of a support panel 20, for example tilted, makes it possible to stiffen the structure of storage 2 and at the same time guides the products inserted in compartment 3, a condition that may facilitate a filling phase of storage 2 with one or more products.

Process

[0194] In addition, the present invention related to a process of making a container 1. The process includes a phase of providing a storage 2; this phase may involve the die-cutting of a flat sheet of paper material to define a blank 50 which, thanks to successive folding and gluing phases, defines said storage 2. The blank 50 for making the storage 2 includes: [0195] at least one central sheet 51, [0196] at least one first and second side sheet 52, 520 opposite to the central sheet 51, said the first and second side sheets 52, 520 being aligned with the central sheet 51 along a first direction, wherein at least one of the said first and second side sheets 52, 520 includes at least one portion suitable for defining said second coupling portion 13 of the container, [0197] at least one first and second peripheral sheet 53, 530 opposite to the central sheet 51 and opposite to the said first and second side sheet 52, 520, said first and a second peripheral sheet 53, 530 being also aligned with the central sheet 51 along the first direction, [0198] at least four closing sheets 55a, 55b, 55c, 55d respectively emerging from the same side, from the central sheet 51, from the first side sheet 52, from the second side sheet 520 and from the second peripheral sheet 530, said closing sheets being aligned with each other with respect to a second direction parallel to that first direction, [0199] at least one additional sheet 56a, 560a joined in a single piece to at least one of the central sheet 51 and the second peripheral sheet 530 on the opposite side with respect to the closing sheets 55a, 55b, 55c, 55d.

[0200] The process includes the following steps: [0201] fold the first and a second side sheet 52, 520 in relation to the central sheet 51 in such a way as to arrange the first and second side sheets substantially facing each other, [0202] fold the first and second peripheral sheets 53, 530 respectively with respect to the first and second side sheets 520 as they approach the central sheet 51, [0203] overlap and join, optionally by gluing, at least part of the first and second peripheral sheets 53, 530 in such a way as to define said at least one side wall of the storage 2, [0204] fold and at least partially overlap the closing sheets 55a, 55b, 55c, 55d, [0205] join at least two of these closing sheets in such a way that they define the bottom wall of the storage 2.

[0206] In fact, the folding steps described above allow the closing sheets to define the bottom wall 4f of the storage and the central, lateral and peripheral sheets to define at least one side wall of the storage. In particular, the first and second side sheets 52, 520, at the end of the folding and constraining phase of the sheets described, are respectively configured to define the front wall 4a and rear 4b of the storage. In detail, these sheets are configured to define the outer panel 41 of the storage; the central sheet 51 and the two overlapping peripheral sheets 53, 530, at the end of the folding and constraining phase of the sheets described above, are instead configured to define respectively the first and second side walls 4c, 4d of the storage 2.

[0207] The process also includes a folding phase of that additional sheet in such a way that, at the end of the folding phase, it defines the support panel 20. As may be seen from FIGS. 13-16, at least one additional sheet of the first blank sheet 50 may include a first additional sheet 56a joined in a single piece with the central sheet 51, directly emerging from said central sheet 51 on the opposite side with respect to the closing sheets, and a second additional sheet 560a joined in a single piece with the second peripheral sheet 530 also emerging directly from said second peripheral sheet 530 on the opposite side with respect to the closing sheets; at the end of the folding phase, the first and second sheets 56a and 560a define the first and second support panels respectively.

[0208] As may be seen from the attached figures, the first blank 50 may also include at least one overlapping sheet 57, 570 joined in a single piece with at least one of the first and second side sheets 52, 520 and emerging on the opposite side with respect to the closing sheets 55a, 55b, 55c, 55d; the process may therefore involve the folding and constraining, for example by gluing, of said at least one overlapping sheet to at least one of the said first and second side sheets 52, 520 to define the internal panel 42 of the storage. In detail, at least one overlapping sheet includes a first overlapping sheet 57 joined in a single piece with the first side sheet 52, said the first overlapping sheet 57, at the end of the folding phase, defining the inner panel of the front wall; at least one overlapping sheet, including a second overlapping sheet 570 joined in a single piece with the second side sheet 520, said the second overlapping sheet 570, at the end of the folding phase, defining the inner panel of the rear wall.

[0209] At least one of these first and second overlapping sheets 57, 570 may include at least one through notch 58a, 58b, 580a, 580b configured to define the seat 30. FIG. 13 shows a first blank that may be used for making the storage shown in FIGS. 5 and 6. As may be seen, this first blank 50 comprises: [0210] a first and a second additional sheet 56a, 560a which, at the end of the folding phase, are configured to define the first and second panels, [0211] a first and second overlapping sheets 57, 570 which, at the end of the folding phase and constraint to the respective first and second side sheets 52, 520, respectively define the inner panels 42 bound to the outer panels 41 of the front wall 4a and rear 4b of the storages, [0212] a cut-out on the first side sheet 52 to define a portion 52a which, at the end of the various folding phases, is suitable for defining the tab 13a of the second coupling portion 13 defined on the outer panel 41 of the front wall 4a, [0213] a cut-out on the second side sheet 520 to define a portion 520a which, at the end of the various folding phases, is suitable for defining the tab 13a of the second coupling portion 13 defined on the outer panel 41 of the rear wall 4b, [0214] two through-notches 58a, 58b defined partly on the first side sheet 52 and partly defined on the first overlapping sheet 57 to define the seats 30 of the front wall 4a, [0215] two through-notches 580a, 580b defined partly on the second side sheet 520 and partly defined on the second overlapping sheet 570 to define the seats 30 of the rear wall 4b.

[0216] FIG. 14 shows a first blank draft that may be used for making the storage shown in FIGS. 7 and 8. Unlike the blank in FIG. 13, the blank 50 in FIG. 14 exhibits: [0217] two through-notches 58a, 58b defined only on the first overlapping sheet 57 to define the seats 30 defined on the inner panel 42 of the front wall 4a, [0218] two through-notches 580a, 580b defined only on the second overlapping sheet 570 to define the seats 30 defined on the inner panel 42 of the rear wall 4b.

[0219] FIG. 15 shows a first blank that may be used for making the storage of FIGS. 9 and 10. Unlike the blank of FIG. 14, the blank 50 of FIG. 15 has: [0220] two through-notches 58a, 58b defined only on the first overlapping sheet 57 to define the seats 30 defined on the inner panel 42 of the front wall 4a, the two notches essentially delimit two opposite sections of the perimeter edge of the first overlapping sheet 57, [0221] two through-notches 580a, 580b defined only on the second overlapping sheet 570 to define the seats 30 defined on the inner panel 42 of the rear wall 4b, the two notches essentially delimit two opposite sections of the perimeter edge of the second overlapping sheet 570.

[0222] FIG. 16 shows a first blank that may be used for the construction of the storage shown in FIGS. 11 and 12. Unlike the blank in FIG. 14, the blank 50 in FIG. 16 has through notches 58a, 58b, 580a, 580b spaced from the first and second lateral sheets, having a substantially rectangular shape.

[0223] The second blank for making the closure system 7 may be joined in a single piece or distinguished from the first blank 50. The closure system may be substantially realized by means of the process for making case described in the patent application PCT No. WO 2021/044266 A1 as published from page 22, line 16, to page 23, line 26, which is incorporated by reference. Alternatively, the closure system may be substantially implemented by means of the process described in the Italian patent application 102022000014821, from page 34, line 18, to page 36, line 24, which is incorporated by reference.

[0224] Compared to the state of the art, the present invention has considerable advantages. In fact, the presence of at least one support panel prevents the side wall of the storage carrying the second coupling portion from undergoing an undesirable deformation, such as to cause the undesirable disengagement of the second coupling portion with the first coupling portion. Thanks to the presence of at least one support panel, it is possible to create an extremely safe container 1, designed to effectively prevent attempts to open it by children.
