Description

FIELD OF THE INVENTION



[0001] The present invention relates to a childproof container and a process of making the same. The container may be used in fields that require the packaging of products and where it is required, for safety reasons, the inhibition of opening the container by children. For example, the container may be used in the packaging fields for products containing tobacco, such as cigarettes, or similar products.

BACKGROUND



[0002] As is well known, childproof containers are available on the market which are designed to be difficult to open by a majority of children under 5 years of age; for example, these types of containers are used in the pharmaceutical field to prevent children from ingesting medications potentially harmful to them and thus prevent accidental poisoning.

[0003] A known type of childproof container is described in patent application No. WO 2016/198978 A1. Such container comprises a store for the storage of products: the store has a passage opening at which a closure system is hinged. Inside the store there is a hook suitable to cooperate with a respective hook carried by the closure system; the hooks of the store and of the closure system are configured to stably engage each other during a closing condition of the closure system so as to prevent the opening of the container. Moreover, the container has one or more slots, defined on a top wall of the closure system, which allow the insertion of a tab inside the container to allow the release of said hooks and thus the opening of the container.

[0004] A different type of container is described in US patent application No. US 2001/030135 A1. Such application describes a tamper evident cigarette package comprising a store for containing cigarettes closable by means of a closure system; during the manufacturing step, the closure system is joined in one piece to the store by means of weakened portions configured to break following a first opening of the package to give evident of a first opening of the package.

OBJECT OF THE INVENTION



[0005] The object of the present invention is therefore to substantially solve at least one of the disadvantages and/or limitations referred to in the state of the art.

[0006] A first objective of the present invention is to provide a childproof container with a simple and compact structure, which can be realized quickly and economically, for example by means of standard apparatus; in particular, it is aim of the present invention to make a container which does not require the modification of the common plants used today for the realization of standard type containers and which also do not require the modification of the existing packaging plants for the filling of the container itself. It is then the purpose of the present invention to provide a container that can be effectively childproof but at the same time can be easily opened by an adult; in particular, it is the purpose of the present invention to provide a container flexible in use that can be opened by an adult with different and common opening devices. The purpose of the present invention is to provide a container that is structurally compact, resistant and at the same time light. It is also the purpose of the present invention to provide a container with a stable structure able to guarantee its integrity following multiple openings and closures of the same.

[0007] These purposes and others, which will appear more from the following description, are substantially achieved by a container and a process of making the same according to one or more of the enclosed claims and/or the following aspects, taken alone or in any combination between them or in combination with any one of the enclosed claims and/or in combination with any one of the further aspects or features described below.

DETAILED DESCRIPTION


Container



[0112] A childproof container is indicated with 1. The container 1 comprises a type of closure and an unlocking portion, which will be described in detail below, which allow the container 1 to be opened only under certain conditions and in particular to prevent it from being opened by children.

[0113] The container 1 comprises a store 2 defining a compartment 3 configured to house one or more products. In more detail, the store 2 comprises a prefixed number of walls and has a substantially parallelepipedic shape. As illustrated in the enclosed figures, store 2 can have a substantially rectangular parallelepiped shape. The store can comprise, in its parallelepipedic form, a front wall 4a, a rear wall 4b opposite the front wall 4a, a first side wall 4c between the front wall 4a and the rear wall 4b and a second side wall 4d opposite the first side wall 4c: the first side wall 4c and the second side wall 4d are interposed between the front wall 4a and the rear wall 4b by opposite parts of the store 2 and connect the front wall 4a and the rear wall 4b at opposite longitudinal edges. The store 2 may also include a rear wall 4e to delimit the compartment 3 below. Alternatively, the store 2 may include a number of side walls other than four. The bottom wall 4e, the front wall 4a, the rear wall 4b and the side walls 4c, 4d cooperate to define a concavity of the compartment 3 facing towards the external environment.

[0114] The front wall 4a, the rear wall 4b and the side walls 4c, 4d define at least one passage opening 5 delimited by a free edge 6. The free edge 6, as well as the passage opening 5, is defined as opposed to bottom wall 4e. The passage opening 5 is configured to connect the compartment 3 of the store 2 with the external environment. The enclosed figures show the container 1 with a single passage opening 5; however, it is not excluded the possibility of creating, for example, a the store 2 without a bottom wall and with two openings defined at the opposite longitudinal ends of the store 2.

[0115] As can be seen in the attached figures, the store 2 can extend longitudinally along a direction of prevalent development, along which a length of the store 2 is defined. The store 2 can be suitably sized according to the type of product and the quantity of product to be contained in the store 2. The container 1 may be of small dimensions, namely it may have a store 2 with a compartment 3 whose volume is substantially comprised between 40,000 and 200,000 mm3. The container 1 may be used for the packaging of medium-sized products; in this condition, the store 2 may have a compartment 3 whose volume is greater than 500,000 mm3, and optionally between 800,000 and 1,400,000 mm3. However, the possibility of using the containers 1 for the packaging of large-sized products is not excluded; in such a case, the store 2 may have a compartment 3 whose volume is greater than the volumes specified above, for example more than 10,000 cm3.

[0116] As can be seen from the attached figures, the container 1 also comprises at least one closure system 7, optionally joined together in one piece, at the rear wall 4b of the store 2 at the free edge 6 and movable in relation to the store 2. In particular, the closure system 7 is hinged to the free edge 6 of the store 2 and movable by rotation in relation to the latter. The closure system 7 is configured to define at least one locking condition (see for example figures 4, 5, 6, 16, 19) and at least one opening condition (see for example figures 2, 9 and 13). In the closing condition, the closure system 7 prohibits the communication between the passage opening 5 and the external environment and consequently between the compartment 3 and the external environment, while in the closing condition the closure system 7 is configured to allow the communication between the passage opening 5 and the external environment and consequently between the compartment 3 and the external environment. From a functional point of view, the closure system 7 essentially represents a lid suitable for cooperating with the store 2 in order to manage access to the compartment 3. In a possible embodiment in which the container 1 comprises a number of passage opening 5, the container 1 may include a closure system 7 for each passage opening 5 in the store 2.

[0117] In more detail, the closure system 7 comprises a top panel 7a, a front panel 7b and a first and second side panel 7c, 7d. The first and second side panels 7c, 7d emerge from opposite parts of the top panel 7a to essentially define the sides of closure system 7. The front panel 7b emerges frontally from top panel 7a in between the first and second side panel 7c, 7d. The closure system 7 may also include a rear panel 7e engaged at the free edge 6 of the store 2. As illustrated in the attached figures, the rear panel 7e of the closure system 7 may be the only constraint of the closure system 7 to the free edge 6 of the store 2. The engagement between the rear panel 7e and the free edge 6 of the store 2, for example engaged by means of a hinge-type constraint, allows the rotation of the closure system 7 between the closed and the opening condition, and vice versa. The rear panel 7e emerges from the top panel 7a on the opposite side to the front panel 7b in interposition between the first and second side panel 7c, 7d. In other words, the rear panel 7e emerges at the rear from top panel 7a. In the closure condition of the closure system 7, the top panel 7a, the front panel 7b, the first side panel 7c, the second side panel 7d and the rear panel 7e cooperate to interdict the access to compartment 3. In structural terms, top panel 7a, the front panel 7b, the first side panel 7c, the second side panel 7d and, where provided, the rear panel 7e, shall cooperate to define a compartment 8 of the closure system bounded by a respective free edge 9 and having a concavity facing, in the closing condition of the closure system 7, towards the compartment 3 of the store 2. In the closing condition of the closing system 7, the concavities of the compartment 3 of the storage unit and the compartment 8 of the closing system 7 shall be opposite each other: the compartment 3 of the storage unit 2 and the compartment 8 of the closing system 7 shall cooperate to define an internal volume of the container 1.

[0118] The container 1 also comprises a panel 10 engaged to the front wall 4a of the store 2. The panel 10 is located in the compartment 3 and faces the rear wall 4b of the store 2. The panel 10 straddles the free edge 6 of the store 2; in other words, the panel 10 comprises a basic portion 10a extending below the free edge 6 of the store 2, namely between the bottom wall 4e and the free edge 6 of the store 2, and an end portion 10b extending beyond the free edge 6 of the store 2. The end portion 10b is joined to the base portion 10a.

[0119] The container 1 also comprises at least one safety device 11 having at least a first coupling portion 12 carried by the front panel 7b of the closure system 7 and at least a second coupling portion 13 engaged to the front wall 4a of the store 2. The first and second coupling portion 12, 13 are configured to stably engage each other during a locking condition of the closure system 7 (see for example Figures 4, 6 and 16). In the closing condition of the closure system 7, the safety device 11, and consequently the container 1, assumes a locking condition in which the opening of the container 1 is prevented by the engagement between the first and second coupling portion 12, 13.

[0120] With regard to the first coupling portion 12, in the closing condition of the closure system 7, it is configured to fit at least partially into the compartment 3 of the store 2 in order to stably engage the second coupling portion 13. As shown in Figures 4 and 6, in the closing condition of the closure system 7, the first coupling portion 12, in the closing condition of the closure system 7, is entirely contained in the internal volume of the container 1 and it is spaced from the free edge 6 of the store 2. In addition, in the closing condition of the closure system 7, the engagement between the second coupling portion 13 and the first coupling portion 12 is completely defined in the internal volume of the container 1. The engagement between the first and second coupling portion 12, 13 is of reversible type; in other words, after reaching the opening condition of the closure system 7, the first and second coupling portion 12, 13 may be engaged again to define again the closing condition of the closure system 7 and consequently a new locking condition of the safety device 11. This is possible because, when switching between the closing and the opening condition, the first coupling portion 12 is simply disengaged from the second coupling portion 13. In other words, according to the embodiments of the container 1 shown in the attached figures, during the passage between the closing condition and the opening condition, the first and second coupling portion 12, 13 are not removed or detached respectively from the closure system 7 and the store 2, but remain engaged to the latter's. In this way, since no removable portions are provided of the safety device 11, the first and second coupling portions 12, 13 are configured to reversibly define, following every opening condition of the closure system 7, a locking condition in which these portions 12, 13 are stably engaged with each other.

[0121] The attached figures illustrate the embodiments of the container 1 in which the first coupling portion 12 is engaged in the front panel 7b of the closure system 7. The first coupling portion 12 and the front panel 7b can be joined together to form a single body. In the embodiments shown in the attached figures, the first coupling portion 12 and front panel 7b are joined together in one piece and the first coupling portion 12 comprises a flat sheet body coplanar to the front panel 7b. In the embodiments shown in the attached figures, the first coupling portion 12 is made of paper sheet material and is elastically deformable. Figure 14 illustrates a deformation condition of the first coupling portion 12 which is generated by the push of a user's finger on the same portion 12 to allow its insertion inside the compartment 3 of the store 2 and the engagement to the second coupling portion 13.

[0122] In more detail, the first coupling portion 12 has at least one hook 14 configured to stably engage the second coupling portion 13 located inside the store 2 in the closing condition of the closure system 7. As illustrated in the accompanying figures, the hook 14, in the closing condition of the closure system 7, is distinct and spaced from the free edge 6 of the store 2. As illustrated in figure 2, the hook 14 defines an undercut 14a having a seat a 14b with a concavity. As illustrated in the attached figures, the the first coupling portion 12 may comprise two hooks 14 with respective undercuts 14a and respective seats 14b whose concavities are opposite each other. The undercut 14a of the hook 14 is configured to engage the second coupling portion 13, as will be seen in more detail below.

[0123] As shown in the attached figures, the second coupling portion 13 is defined at the base portion 10a of the panel 10. The second coupling portion 13 comprises a main body 15 and a hook 16 engaged to the main body 15. The hook 16 is configured to allow the engagement of the hook 14 of the first coupling portion 12 to the second coupling portion 13 in the locking condition of the safety device 11. Between the hook 16 and the main body 15 is defined as a passage seat 17 having a concavity facing opposite the free edge 6 of the store 2; the passage seat 17 is at least partially bounded by the hook 16. In the attached figures, a passage seat 17 is shown whose concavity points towards the bottom wall 4e of the store 2. The passage seat 17 basically defines a window in the panel 10 act to allow the insertion of the first coupling portion 12; the first coupling portion 12 is inserted in passage seat 17 (see figure 3 illustrating the phase of insertion of the first coupling portion 12 in passage seat 17) to be guided in engagement to the second coupling portion 13 (see figure 6 illustrating the closing condition of the closure system 7). As illustrated for example in Figures 3, 4, 6 and 8, the passage seat 17 may be formed by a notch defined on the second coupling portion 13 between the main body 15 and the hook 16.

[0124] From a structural point of view, the hook 16 comprises a central body 16 'and a first and second connecting ends 16",16'" opposed to the central body 16' (figure 6). The first and second connecting ends 16", 16'" develop laterally to the central body 16', which is therefore interposed between them, and constrain the central body 16' to the main body 15 of the second coupling portion 13.

[0125] The central body 16' and the first and second connecting ends of the 16", 16'" define an undercut 16a of the hook 16 and delimit the passage opening 17. The passage seat 17 allows the undercut 14a of the first coupling portion 12 to engage the undercut 16a of the second coupling portion 13 in the locking condition of the safety device 11; the locking condition is illustrated for example in figure 6.

[0126] The container 1 also comprises at least an unlocking portion 18. The unlocking portion 18 is defined at the front panel 7b of the closure system 7. The unlocking portion 18 is configured to allow the closure system 7 to switch from the closing condition to the opening condition. The unlocking portion 18 is configured to define at least a through access 19. The through access 19 allows the access, under certain conditions and by means of appropriate opening devices detailed below, to the internal volume of the container 1 to operate on the closure system 7 to allow the passage of closure system 7 from the closing condition to the opening condition. The through access 19 is distanced from the free edge 9 of the closure system 7 and shall be spaced from the top panel 7a of the closure system 7. The through access 19 is configured to allow, in the locking condition of the safety device 11, the insertion of an opening device 20 into the inner volume of the compartment of the container 1. The opening device 20 is designed to allow the disengagement between the first and second coupling portion 12, 13 and consequently the passage of the closure system 7 from the closing condition to the opening condition. The through access 19 is perimetrically delimited by a closed path profile developing completely on the front panel 7b of the closure system 7. The closed path profile delimits a free passage section of the through access 19. The free passage section may be suitably sized to allow easy insertion of the opening device 20. Optionally, the free passage section of through access 19 is at least partially counteshaped the opening device 20. As illustrated in the attached figures, the through access 19 is defined in correspondence of a portion of the front panel 7b intended to be facing, in the closing condition of the closure system 7, to the extremal portion 10b of panel 10. The attached figures illustrate embodiments in which the unlocking portion 18 has two through accesses 19 having the same rectangular profile, spaced out each other and defined completely in correspondence with the front wall 7b of the closure system 7 at the same distance from the top panel 7a. In possible variants, the number of the through accesses 19 may differ from two, the profile of the through accesses 19 may differ in shape or size and the through accesses 19 may be located at different distances from the top panel 7a.

[0127] The container 1 may include an opening device 20. The opening device 20 may have one or more of the characteristics described above. The opening device 20 is configured to allow the passage of the closure system 7 from the closing condition, corresponding to the locking condition of safety device 11, to the opening condition. The opening device 20 can therefore ensure the opening of the container 1 by operating on the safety device 11 in such a way as to determine the disengagement between the first and second coupling portion 12, 13. The opening device 20 may be supplied to a user together with the container 1. In this embodiments, the free passage section of the through access 19 and the opening device 20 may be at least partially counter-shaped from each other. The opening device 20 is dimensioned and designed to be inserted, in the closing condition of the closure system 7, at least partially into the internal volume of the container 1 through the through access 19. The opening device 20 may be made of paper sheet material; however, the opening device 20 may be made of other materials, such as plastic sheet or metal sheet material. From a structural point of view, the opening device 20 has a gripping portion 21 from which one or more appendices 22 emerge (see, for example, Figures 7 and 9). The appendices 22 may have a polygonal shape, for example substantially square or rectangular or trapezoidal. The appendices 22 are configured and dimensioned to fit inside a respective through access 19 in such a way that they are guided to the safety device 11, to contact, in the closing condition of the closure system 7, the first and the second coupling portion 12, 13 and to disengage them. The appendices 22 are developed away from a stop edge 23 interposed between them. The stop edge 23 allows the opening device 20 to enter, in the closing condition of the closure system 7, partially into the internal volume of the container 1, in such a way that the appendices 22 are arranged inside the volume of the container 1 while the gripping portion 21 remains outside the container 1. At a condition of maximum penetration of the opening device 20 into the inner volume of the container 1, the stop edge 23 may be at the stop with a section of the unlocking portion 18 interposed between the through access 19; said section acts as a stop limit for the opening device 20 and prevents the opening device 20 from entering completely, in the closing condition of the closure system 7, the inside volume of the container 1. The opening device 20 may have substantially shaped 'C' or 'U' or 'W' or 'H' or 'A'.

[0128] The container 1 also comprises a guide body 24. The guide body 24 is configured to guide, in the closing condition of closure system 7, the opening device 20 towards the safety device 11. For this purpose, the guide body 24 is arranged with respect to the through access 19 in such a way that it is contacted, for example by the appendix 22 of the opening device 20, when inserting the opening device 20 into the internal volume of the container 1, by the opening device 20. In other words, the guide body 24 is arranged in such a way that it is intercepted by the opening device 20 when it is inserted into the internal volume of the container 1; by intercepting the opening device 20, the guide body 24 directs the opening device 20 towards the safety device 11. In essence, the guide body 24 is arranged in such a way that a plurality of possible inserting directions of the opening device 20 into the inner volume of the container 1 intercept the guide body 24. With reference to the closing condition of the closure system 7, the guide body 24 is placed in the internal volume of the container 1 and faces the unlocking portion 18; in more detail, the guide body 24 develops in the compartment 8 of the closure system 7 (see figure 3). The guide body 24 can be directly facing the through access 18. Providing that guide body 24 faces the unlocking portion 18, and in particular directly facing the through access 19, allows the guide body 24 to guide, in the closing condition of the closure system 7, the opening device 20 to the safety device 11. The guide body 24 is made of sheet material and is carried by at least one between the second coupling portion 13 and the closure system 7. The attached figures illustrate the embodiments of the container 1 in which the guide body 24 is carried by the second coupling portion 13. The guide body 24 can develop at the extremal portion 10b of the panel 10 and can therefore be defined as the portion of the panel 10 that emerges beyond the free edge 6 of the container 2. The guide body 24 therefore develops at a greater height, defined as the distance from the bottom wall 4e, to the height at which the free edge 6 of the storage 2 develops. Under the functional point of view, the guide body 24 basically defines a ramp, with respect to which the opening device 20 can slide or slide towards the safety device 11. In order to guide the opening device 20 towards the safety device 11 to work on it, the guide body 24 is facing and positioned behind the through access 19; in that regard see figure 16.

[0129] As will be described in detail below with reference to the method of opening the container 1, the guide body 24 guides the opening device 20 towards the first coupling portion 12 of the safety device 11 in such a way as to contact it and consequently allow the disengagement from the second coupling portion 13.

[0130] The container 1 may also include a pushing device 25; in that regards see for example figures 13 to 16. the pushing device 25 is placed in the compartment 3 of the storage unit 2 near the second coupling portion 12. The pushing device 12 shall be configured to allow the engagement between the first and second coupling portion 12, 13 and, in the locking condition of the first and second coupling portion 12, 13, keep the safety device 11 in the locking condition. For this purpose, the pushing device 25 is configured to act in push on at least one of the first and second coupling portions 12, 13. As shown in Figures 13 to 16, the pushing device 25 is configured to act in push on the first coupling portion 12. The pushing device 25 passes through the passage seat 17 of the hook 16 of the second coupling portion 13; this arrangement allows the pushing device 25 to operate on the first coupling portion 12. The pushing device 25 is of the elastically deformable type. As shown in the attached figures, the pushing device 25 is elastically movable between a thrusting and a resting condition. In the thrusting condition the pushing device 25 operates in push on the first coupling portion 12, in the closing condition of the closure system 7, to maintain the first coupling portion 12 in engagement on the second coupling portion 13. The pushing device 25, on the other hand, assumes the resting condition in the opening condition of the closure system 7, in which the pushing device is not stressed by the first coupling portion 12. Figure 15 shows an operating condition of the container 1 intermediate between the opening condition of the closure system and the closing condition of the closure system 7; this intermediate operating condition is reached by the movement of the closure system starting from the closing condition and provides the partial insertion of the first coupling portion 12 into the passage seat 17. In the configuration of figure 15, the pushing device 25 is placed inside the passage seat 17 and operates, in the thrusting condition, on the first coupling portion 12, which results wedged between the pushing device 25 and the second coupling portion 13. Figure 16 illustrates the closing condition of the closure system 7 which, with reference to the passage of the closure system 7 from the opening to the closing condition, is subsequent to the configuration illustrated in figure 15 with reference to a closing operation of the container 1. In the closing condition, the pushing device 25 is in the thrusting condition and operates in push on the first coupling portion 12 in order to maintain it engaged with the second coupling portion 13 in order to maintain the locking condition of the safety device 11. Upon transition of the container 1 from the intermediate condition shown in figure 15 to the closing condition of the closure system 7 shown in figure 16, the pushing device 25 acts on the hook 14 of the first coupling portion 12 to move it away from the front wall 4a and allowing the step engagement at the hook 16 of the second coupling portion 13. In the locking condition of the safety device 11 thus reached, the undercut 14a of the hook 14 of the first coupling portion 12 and the undercut 16a of the hook 16 of the second coupling portion 13 are attested to each other. From a structural point of view, the pushing device 25 comprises a tab made of sheet material. In order to provide elasticity to the pushing device 25 to allow its elastic movement as described above, the tab may be made of paper sheet material. In possible variations, the tab 25 may be made of elastically deformable material different from paper sheet material. The tab 25 is joined in one piece to the front wall 4a of the store 2. The tab 25 is joined in one piece to the free edge 6 of the store 2 and is folded around the free edge 6 in such a way that it results placed inside the passage seat 17 in front of the panel 10. The positioning of the tab 25 inside the passage seat 17 defined on the panel 10 can help prevent the springback of the tab 25 after it has been folded over the free edge 6 of the store 2. As shown in the attached figures and with reference to a lateral section of the container 1, in the resting condition, the tab 25 assumes with respect to a front wall 4a of the store 2 a first angular position (see figure 14) with a certain angular width, while in the thrusting condition, the tab 25 assumes with respect to a front wall 4a of the store 2 a second angular position (see figure 16) having a respective angular width smaller than the angular width that the tab 25 assumes in the first angular position. The tab 25 is elastically movable between the first and the second angular position by means of the first coupling portion 12; for example, the tab 25 is elastically movable between the first and the second angular position when inserting the first coupling portion 12 into the passage seat 17 (see figure 15), while it is movable from the second to the first angular position when disengaging the first coupling portion 12 from the second coupling portion 13.

[0131] As shown in Figure 18, the container 1 may include a tamper evident portion 26. The tamper evident portion 26 is configured to operate between an intact condition and a violated condition (see Figure 19). In the intact condition the tamper evident portion 26 prevents access to the through access 19, while in the violated condition the tamper evident portion 26 allows access to the through access 19, for example to allow the opening of the container 1 by the opening device. The tamper evident portion 26 assumes the intact condition in an unbroken condition of the container 1 in which the container 1 has not yet been opened for the first time, while at the first opening or first attempt to open the container 1, the tamper evident portion 26 is configured to pass non-reversibly from the intact condition to the violated condition. Figure 18 shows the transition of the tamper evident portion 26 from the intact condition to the violated condition. The tamper evident portion 26 comprises a removable portion that can be associated with the unlocking portion 18. In the intact condition, the removable portion 26 is engaged frontally to the unlocking portion 18 in such a way as to occlude the through access 19, while in the violated condition the removable portion 26 is at least partially removed from the unlocking portion 18 and allows the access to the through access 19. The removable portion 26 may include a removable panel, such as a tear-off panel (see Figure 18). In another possible embodiment, the removable portion 26 may include a plastically deformable membrane, such as a fracturable membrane.

Method of opening the container



[0132] This invention also relates to a method of opening a container 1 according to any one of the accompanying claims. The method of opening the container 1 involves the preparation of the container 1 according to any one of the embodiments described above. The previously prepared the container 1 has the closure system in closing condition. If the container has no through access, the method of opening the container 1 involves the definition of at least a through access 19 on the unlocking portion 18. The phase of defining at least one through access 19 may involve releasing the through access 19, for example by removing a removable panel act to occlude the through access 19; the removable panel may, for example, be counter-shape to the through access 19. The method involves the at least partial insertion of the opening device 20 through the through access 19. The at least partial insertion of the opening device 20 involves the insertion of at least an appendix 22 within the respective through access 19. In case the two appendices 22 are provided, the at least partial insertion of the opening device 20 involves the insertion of each appendix 22 within the respective through access 19. The method may involve inserting the opening device 20 into the inner volume of the container 1 through the through access 19 until a condition of maximum penetration of the opening device 20 into the inner volume of the container 1 is reached; said step involves bringing in hammering the stop edge 23 of the opening device 20 with a section of the unlocking portion 18 interposed between the through accesses 19. The configuration for inserting the opening device 20 into the inner volume of the container 1 is exemplarily shown in figure 7 and figure 8. When the opening device 20 is inserted into container 1, the opening device 20 contacts the guide body 24, which guides the opening device 20 towards the safety device 11. Under the guidance of the guide body 24, the opening device 20 reaches the safety device 11 and contacts at least one between the first coupling portion 12 and the second coupling portion 13 to disengage the first and second coupling portion 12, 13. According to the embodiments of the container 1 shown in the attached figures, the guide body 24 is configured to guide the opening device 20 towards the safety device 11 such that it contacts the first coupling portion 12. in the following will be described the embodiments of the method in which the opening device 20 contacts the first coupling portion 12 to unlock the safety device 11; however, in a possible variant, the method may involve contacting the second coupling portion 13 to unlock the safety device 11 or both the first coupling portion 12 and the second coupling portion 13. The guide body 24 guide the opening device 20 in interposition between the first portion of coupling 12 and the passage seat 17; in said condition, illustrated as an example in Figure 8, the appendices 22 of the opening device 20 are interposed between the first coupling portion 12 and the passage seat 17. The interposition of the opening device 20 between the first coupling portion 12 and the passage seat 17 makes it possible to disengage an undercut 14a of the first coupling portion 12 from a undercut 16a of the second coupling portion 13. In the embodiment of the method involving the provision of a the container 1 comprising the pushing device 25, such as the container 1 shown in Figures from 13 to 16, when the opening device 20 is inserted into the internal volume of the container 1, the method involves, at the stage when the opening device 20 is placed in interposition between the first coupling portion 12 and the passage seat 17, to overcome an elastic thrust exerted by the pushing device 25 on the first coupling portion 12 in such a way as to disengage the undercut 14a of the first coupling portion 12 from the undercut 16a of the second coupling portion 13. After disengaging the first coupling portion 12 from the second coupling portion 13, the method involves moving by rotation the closure system 7 with respect to the store 2. Said phase may involve moving the opening device 20 integrally with the closure system 7, optionally by rotation; in this respect, see figure 9.

[0133] An embodiment of the method that provides for the preparation of the container 1 with a tamper evident portion 26, in order to determine the opening of the container 1 the method provides, at the time of a first opening of the container 1 or a first attempt to open the container 1, to non-reversibly determine the passage of the tamper evident portion 26 from the intact condition to the violated condition in such a way as to make accessible the through access 19. Said step is prior to the phase of the at least partial insertion of an opening device 20 through the through access 19 and may involve removing a removable portion 26 or tearing a tearable portion from the unlocking portion 18 and, in addition or alternatively, plastically deforming a membrane, for example by fracturing it.

Container manufacturing procedure



[0148] Furthermore, it is an object of the present invention a procedure for making a container 1 according to any of the accompanying claims. The container 1 made by said process is of the type described above.

[0149] The container 1 is made from a single sheet of blank 50, for example in paper material, of the type described above. As will be seen in detail below, the procedure involves folding the blank 50 and the connection of some of its portions, for example by gluing, to form the container 1.

[0150] The procedure for the realization of a the container 1 involves the arrangement of a blank 50 of the type previously described. Optionally, the process may include the arrangement of at least one product. The procedure may involves the preparation of several products, for example the type containing tobacco, such as cigarettes or cigars, or the type suitable for use with a product containing tobacco.

[0151] The process of making a the container 1 starting from the blank of figures 1 and 12 is now described.

[0152] The procedure involves folding the side connection portions 69, 70 of the third sheet 67 with respect to the first portion 68 of the third sheet 67 and involves the arrangement the first portion 68 of the third sheet 67 in front of the first portion 52 of the first sheet 51. The phase prior the arrangement of the first portion 68 of the third sheet 67 frontally to the first portion 52 of the first sheet 51 is shown in figure 10, while the phase in which the first portion 68 of the third sheet 67 is arranged frontally to the first portion 52 of the first sheet 51 is shown in figure 11. Said phase involves the disposition of a notch 170 (see blank 50 of figure 1) or of a window (see blank 50 of figure 12) in front of the first portion 52 of the first sheet 51; the window defines, in an assembled condition of the container 1 obtainable through the procedure of realization of the container 1 here described, the passage seat 17. The phase of arrangement of the first portion 68 of the third sheet 67 frontally to the first portion 52 of the first sheet 51 also involves for the formation of the second coupling portion 13 and of the guide body 24. Said step can be carried out in such a way that the first lateral connecting portion 69 of the third sheet 67 and the second lateral connecting portion 70 of the third sheet 67 are arranged at an inner space of the first sheet 52 defined between the first and second lateral connecting portion 55, 56 of the first sheet 51 (condition shown in Figure 11); surfaces of the first lateral connecting portion and the second lateral connecting portion 69, 70 of the third sheet 67 facing the inner space are essentially inner surfaces of the first lateral connecting portion and of the second lateral connecting portion 69, 70 of the third sheet 67. The procedure involves joining the first lateral connecting portion 69 of the third sheet 67 to the first lateral connecting portion 55 of the first sheet 52 by gluing an outer surface of the first lateral connecting portion 69 of the third sheet 67 to an inner surface of the first lateral connecting portion 55 of the first sheet 51. Similarly, the procedure may involve joining the second lateral connecting portion 70 of the third sheet 67 to the second lateral connecting portion 56 of the first sheet 51 by gluing an outer surface of the second lateral connecting portion 70 of the third sheet 67 to an inner surface of the second lateral connecting portion 56 of the first sheet 51. In this way, the third sheet 67 is engaged at the inner space of the first sheet 51 defined between the first and second lateral connecting portion 55, 56 of the first sheet 51.

[0153] The procedure may involves the arrangement of at least one product on an area of blank 50 intended to form an inner surface of a wall of storage room 2. For example, the product or a number of products may be placed on an area of sheet 51, for example, an area of the first portion 52 of sheet 51 intended to form an inner surface of the rear wall 4b of storage room 2 facing compartment 3 of store 2. Said phase is realized such that the product is interposed between the first portion 52 of the first sheet 51 and the first portion 68 of the third sheet 67. The arrangement of the product on blank 50 may be carried out earlier than the arrangement of the first portion 68 of the third sheet 67 compared to the first portion 52 of the first sheet 51.

[0154] The procedure involves the formation of the store 2. The store 2 is formed by folding and joining the lateral connecting portions 55, 56, 57, 58. The lateral connecting portions 55, 56, 57, 58 can be joined by gluing. The formation of the store 2 involves the arrangement, by folding the blank 50, first and second portion 52, 53 of the first sheet 51 in front of each other so that the central connecting portion 54 forms a bottom wall 4e of the store 2. During the phase of arrangement of the first and second portion 52, 53 of the first sheet 51 facing each other, the third lateral connecting portion 57 of the first sheet 51 and the first lateral connecting portion 55 of the first sheet 51 are brought closer and the fourth lateral connecting portion 58 of the first sheet 51 and the second lateral connecting portion 56 of the first sheet 51 are brought closer each other; said condition can be achieved by bringing the second portion 53 of the first sheet 51 closer to the first portion 68 of the third sheet 67 starting from the condition of the blank 50 shown in figure 11. The third lateral connecting portion 57 of the first sheet 51 and the first lateral connecting portion 55 of the first sheet 51 are then joined together and the fourth lateral connecting portion 58 of the first sheet 51 and the second lateral connecting portion 56 of the first sheet 51 are joined together, for example by gluing. The joining phase between the third lateral connecting portion 57 of the first sheet 51 and the first lateral connecting portion 55 of the first sheet 51 can be carried out by gluing an outer surface of the first lateral connecting portion 55 of the first sheet 51 to an inner surface of the third lateral connecting portion 57 of the first sheet 51. Similarly, the joining phase between the fourth lateral connecting portion 58 of the first sheet 51 and the second lateral connecting portion 56 of the first sheet 51 can be performed by gluing an outer surface of the second lateral connecting portion 56 of the first sheet 51 to an inner surface of the fourth lateral connecting portion 58 of the first sheet 51.

[0155] The procedure also comprises the formation of the closure system 7. Said phase involves folding the first, second and third portions 60, 61, 62 of the second sheet 59 so as to respectively form the rear panel 7e, the top panel 7a and the front panel 7b of the closure system 7. The formation phase of the closure system 7 also involves the formation of the first and the first and second side panels 7c, 7d of the closure system 7 as described below. The formation of the side panels 7c, 7d of the closure system 7 involves folding the sixth portion 65 and the seventh portion 66 of the second sheet 59 with respect to the third portion 62 and approaching it in such a way as to define an internal space between them; surfaces of the sixth and seventh portion 65, 66 facing the internal space are essentially internal surfaces of the sixth and seventh portion 65, 66. The formation phase of the closure system 7 also involves folding the fourth and fifth portions 63, 64 of the second sheet 59 with respect to the first portion 60 of the second sheet 59 and approaching with respect to it; at this point, the fourth and fifth portions 63, 64 of the second sheet 59 are placed in correspondence with the internal space defined between the sixth and seventh portions 65, 66 of the second sheet 59. The formation phase of the closure system 7 also involves joining the sixth portion 65 to the fourth portion 63 of the second sheet 59, for example by gluing an inner surface of the sixth portion 65 to an outer surface of the fourth portion 63, and involves joining the seventh portion 66 to the fifth portion 64 of the second sheet 59, for example by gluing an inner surface of the seventh portion 66 to an outer surface of the fifth portion 64. The sixth and fourth portions 65, 63 of the second sheet 59 thus joined form the first side panel 7c of the closure system 7 and the seventh and fifth portions 66, 64 of the second sheet 59 thus joined form the second side panel 7d of the closure system 7.

[0156] The procedure also comprises the arrangement of the fourth sheet 71 to form the first coupling portion 12 of the safety device 11. The first coupling portion 12 is defined by the first portion 72 of the fourth sheet 71.

[0157] The procedure may also include the phase of forming the pushing device 25. With reference to the blank of figure 12, the formation of the pushing device 25 involves folding the fifth sheet 73 with respect to the extremal edge 53a of the second portion 53 of the first sheet 51 so that it results facing the second portion 53 of the first sheet 51. With reference to the formation of the store 2 described above, when the second portion 53 of the first sheet 51 is placed frontally with respect to the first portion 68 of the third sheet 67, the procedure involves moving the fifth sheet 73, already folded, integrally with the second portion 53 of the first sheet 51 and inserting the first portion 74 of the fifth sheet 73 into the slot 170 or into the window 17 of the third sheet 67 in such a way as to form the pushing device 25 in rest condition in the compartment 3 of the store 2.

[0158] The process of making a the container 1 from the blank of Figure 17 is now described.

[0159] The procedure involves forming the store 2 by joining the lateral connecting portion 69 of the third sheet 67 to the central connecting portion 54 of the first sheet 51, optionally by gluing. This phase is carried out by moving the third sheet 67 in such a way that, following the joining of the lateral connecting portion 69 of the third sheet 67 to the central connecting portion 54 of the first sheet 51, the first portion 68 of the third sheet 67 is placed frontally with respect to the first portion 52 of the first sheet 51 to form the panel 10 and then the second coupling portion 13 and the guide body 24. In this way, window 17 of the first portion 68 of the third sheet 67 results facing the first portion 52 of the first sheet 51. The formation of the store 2 also involves folding the foldable portion 51a of the first sheet 51 with respect to the second portion 53 of the first sheet 51; in essence, the foldable portion 51a of the first sheet 51 is flattened to the second portion 53 of the first sheet 51. The foldable portion 51a of the first sheet 51 is then joined to the second portion 53 of the first sheet 51, for example by gluing together the mutually facing inner surfaces of the second portion 53 of the first sheet 51 and the foldable portion 51a. The procedure then involves folding the fifth sheet 74 with respect to the extremal edge 51a' of the tilting portion 51a as it approaches an outer surface of the tilting portion 51a to form the pushing device 25. Following the joining of the lateral connecting portion 69 of the third sheet 67 to the central connecting portion 54 of the first sheet 51, the tilting portion 51a and the second coupling portion 13, which are now joined together as they were previously joined, are moved in such a way that the outer surface of the tilting portion 51a is located at an outer surface of the first portion 68 of the third sheet 67. The outer surface of the first portion 68 of the third sheet 67 may be defined as the surface opposite an inner surface of the first portion 68 of the third sheet 67, which is facing and directly facing the first portion 52 of the first sheet 51 forming the rear wall 4b of the store 2. The step that involves placing the tilting portion 51a on the outer surface of the first portion 68 of the third sheet 67 involves to insert the pushing device 25 in the window 17 of the third sheet 67 in such a way as to position the pushing device 25 in compartment 3 of the store 2. Optionally, the tilting portion 51a may be glued to the outer surface of the first portion 68 of the third sheet 67 to form the front wall 4a of the store 2. The step involving placing the tilting portion 51a on the outer surface of the first portion 68 of the third sheet 67 also involves placing the fourth portion 51c of the first sheet 51 in front of the third portion 51b of the first sheet 51, or vice versa. These portions may be folded with respect to the respective folding edges defined at the respective extremal edges 53a, 52a of the second portion 53 and the first portion 52 in such a way as to arrange the third portion 51b of the first sheet at the fourth portion 51c of the same first sheet 51. The third and fourth portions 51b, 51c of the first sheet 51 can then be joined together, for example by gluing, to form the bottom wall 4e of storage room 2. The procedure may also involve forming the tamper evident portion 26. The formation of the tamper evident portion 26 involves folding the third portion 78 of the sixth sheet 75 with respect to the first and second portions 76, 77 of the sixth sheet 75 and also involves moving the sixth sheet 75 towards the second sheet 59. The sixth sheet 75 can be moved together with the second portion 53 of the first sheet 51 in such a way as to bring, for example in the phase involving the arrangement the tilting portion 51a joined to the second portion 53 of the first sheet 51 to the first portion 68 of the third sheet 67, the tilting portion 51a joined to the second portion of the first sheet to the first portion 52 of the first sheet 51 and simultaneously bring the sixth sheet 75 to the second sheet 59. The third portion 78 of the sixth sheet 75 can be joined, for example by gluing, to the second portion 61 of the second sheet 59 and optionally to the seventh portion 66 of the second sheet 59. The joining of third portion 78 of sixth sheet 75 to the second portion 61 of second sheet 59 may be made by gluing an outer surface of the third portion 78 of sixth sheet 75 to an inner surface of the second portion 61 of second sheet 59 intended to face, in the assembled condition of the container 1, the compartment 8 of the closure system 7.

[0160] Eventually, the process of making the container 1 may include a stage of providing the seventh sheet to form an opening device 20.

[0161] The manufacturing process therefore makes it possible to create a childproof the container 1 of the type described above. At the end of the procedure, a the container 1 is obtained whose closure system 7 is in the opening condition and, where provided, in which the pushing device 25 is in the resting condition and, in addition or alternatively, in which the tamper evident portion 26 is in the intact condition, in which it prevents access to through access 19. The closure system 7 of the container 1 may then be brought into the closing condition; in this condition, the container 1 may be opened, by an adult, by means of the opening device 20 according to the opening method previously described.
