Abstract
Description
[0001] The present invention relates to a container for storing goods, in particular a folding box made of cardboard, paper or the like, comprising a front wall and a rear wall, side walls connecting the front and rear walls and at least one bottom wall and a lid construction, wherein the lid construction comprises at least one upper lid element hinged to the end of the rear wall opposite the bottom wall via a bending line and a front lid flap at the end of the upper lid element opposite the rear wall as well as side flaps laterally closing the lid construction, and at least one locking flap for locking the lid construction to the front wall in the closed state of the container is hinged to the end of the front wall opposite the bottom wall via a bending line in such a way that it rests against an outer side of the front wall or projects outwards from the container.The invention also relates to a blank for producing a container for storing goods, in particular for producing a folding box made of cardboard, paper or the like.
[0002] A wide variety of containers and blanks for producing containers of the type mentioned above are known. In many areas of everyday life, however, it is necessary that these containers cannot be opened easily. In particular, when storing fragile goods or goods such as medicines, it is necessary to secure the containers against accidental opening. This particularly applies to accidental opening of the containers by children. Such containers are known, for example, from DE 94 03 624 U1 and IT MI20 110 947 A1. A disadvantage of these known containers, however, is that they can be very easily deformed by applying pressure in the area of the locking tabs and thus in the area of the opening and closing mechanism. Frequent opening and closing of the container can therefore lead to irreversible deformation, which can destroy the closing and opening function.
[0003] It is therefore an object of the present invention to provide a container for storing goods and a corresponding blank for producing this container, which can be securely closed, is secured against accidental opening and ensures safe opening and closing even when used frequently.
[0004] To achieve these objectives, a container having the features of claim 1 and a blank having the features of claim 12 are provided. Advantageous embodiments of the container according to the invention and the blank according to the invention are described in the respective subclaims. Advantageous embodiments of the container are to be regarded as advantageous embodiments of the blank, and vice versa.
[0005] A first aspect of the invention relates to a container for storing goods, in particular a folding box made of cardboard, paper or the like, comprising a front wall and a rear wall, side walls connecting the front and rear walls, and at least one bottom wall and a lid construction, wherein the lid construction comprises at least one upper lid element hinged to the end of the rear wall opposite the bottom wall via a bending line and a front lid flap at the end of the upper lid element opposite the rear wall, as well as side flaps laterally closing the lid construction, and at least one locking flap for locking the lid construction to the front wall in the closed state of the container is hinged to the end of the front wall opposite the bottom wall via a bending line, in such a way that it rests against an outer side of the front wall or projects outwards from the container.At least one inner flap is hinged to the end of the front lid flap opposite the upper lid element, such that the inner flap at least partially rests on and / or is connected to an inner side of the front lid flap, and at least one first reinforcing element is hinged to the inner flap, such that the first reinforcing element at least partially rests on and / or is connected to an inner side of the upper lid element. In particular, the first reinforcing element can be at least partially glued to the inner side of the upper lid element. The design according to the invention ensures, on the one hand, secure and automatic closure of the container by means of the locking flaps. The locking flaps lock in particular to an inner side of the lid construction and thus secure the lid construction automatically, i.e. without any further measures being necessary, against unintentional opening.To open the container, the locking tabs must be released from their engagement with the lid structure. This can be achieved, for example, by applying pressure to the front wall of the container or a front wall of the lid structure. The inner tab and the first reinforcement element hinged to it significantly reinforce the lid structure, so that even after repeated opening and closing of the container, no irreversible deformation can occur in the area of the locking tabs. The term "bending line" can be understood as all lines that allow elements of the container or the blank to be bent relative to one another along a defined path. In addition to the bending lines mentioned above, folding, perforation, or creasing lines, or a combination of these lines, can also be used.It is also possible to use combinations of these lines with intersection lines.
[0006] In a further advantageous embodiment of the container according to the invention, at least one second reinforcing element is hinged to the end of the first reinforcing element opposite the inner flap, such that it at least partially rests on the first reinforcing element and / or is connected to it. This advantageously results in further reinforcement of this area of the container or the lid structure in this area. In particular, the second reinforcing element can be at least partially glued to the first reinforcing element.
[0007] In further advantageous embodiments of the container according to the invention, at least one recess for receiving the locking tab and at least one pressure tab are formed in the region of the recess on an inner side of the lid construction, wherein, when the container is closed, the locking tab can be brought out of its locking engagement with the recess upon pressure being exerted on the pressure tab in the direction of an interior of the container. The appropriate design of the pressure tabs ensures easy opening of the lid construction or the container. When pressure is applied, the pressure tabs touch the locking tabs and disengage them from the aforementioned recess. The pressure tab can also be designed as a pressure field, a simple opening, or a haptic touch field.Additional security against accidental opening of the container is provided by the fact that when several, in particular two, locking tabs and corresponding pressure tabs are designed, the container can no longer be opened with one hand. Two hands must always be used to open the container, which provides additional security against accidental opening of the container or the lid construction. The recess for receiving the locking tab can be formed entirely in the inner tab or in the inner tab and the first reinforcing element. The pressure tab can be formed in the front lid tab. It is also possible for at least two recesses to be formed on the inside of the lid construction for receiving the locking tabs. The recesses can be connected to one another via a connecting section and form a continuous recess.Overall, this results in a very stable and load-bearing design of the lid construction.
[0008] In further advantageous embodiments of the container according to the invention, the locking tab can be designed as an element of an intermediate tab hinged to the front wall of the container via a corresponding bending line. Designing the locking tab as an element of the intermediate tab also enables simple and cost-effective production of the container. The intermediate tab can, in particular, also serve as a partial cover for the interior of the container or as an intermediate floor in the interior of the container.
[0009] In advantageous embodiments of the container according to the invention, an outline of the locking tab is defined by a cut or perforation line formed in the intermediate tab and the bending line connecting the ends of the cut or perforation line, which is formed between the front wall and the intermediate tab. The outline of the locking tab can also be defined by a cut or perforation line formed in the intermediate tab and the front wall. Furthermore, it is possible for the cut or perforation line to be surrounded by another cut or perforation line to form a gap between the cut or perforation line and the intermediate tab. The formation of this gap ensures a high degree of mobility of the locking tab. This is particularly important since the locking tab is intended to rest against the outside of the front wall or to protrude outwards from the container.
[0010] In further advantageous embodiments of the container according to the invention, at least one further, third reinforcing element is hinged to the end of the intermediate flap opposite the front wall, such that the third reinforcing element at least partially rests against and / or is connected to an inner side of the intermediate flap. In particular, the third reinforcing element can be at least partially bonded to the intermediate flap over its entire surface. At least one engagement recess or engagement opening can be formed at the end of the intermediate flap opposite the front wall. The intermediate flap, which - as mentioned above - can also serve in particular as a partial cover for the interior of the container or as an intermediate floor in the interior of the container, is made more stable and thus more resilient by the third reinforcing element.The possibility of creating an access recess or opening makes it easier to fold back the intermediate flap and thus to release the interior of the container.
[0011] Furthermore, it is possible for the lid construction to be designed such that, when the container is closed, an inner side of the upper lid element, which forms the end of the lid construction, rests at least partially on an end of the side walls and / or the front wall opposite the base construction. This also serves to securely close the container, in particular ensuring that, for example, free-flowing goods can be safely stored inside the container.
[0012] A second aspect of the present invention relates to a blank for producing a container for storing goods, in particular for producing a folding box made of cardboard, paper or the like. The blank comprises a front wall, a rear wall and corresponding side walls as well as at least one bottom wall and a lid construction, wherein the lid construction comprises at least one upper lid element hinged to the end of the rear wall opposite the bottom wall via a bending line and a front lid flap hinged to the end of the upper lid element opposite the rear wall via a bending line. In addition, at least one locking flap is hinged to the end of the front wall opposite the bottom wall via a bending line (80).According to the invention, at least one inner flap is also formed, which is hinged to the end of the front lid flap opposite the upper lid element, and at least one first reinforcing element is formed, which is hinged to the end of the inner flap opposite the front lid flap. The blank according to the invention ensures, on the one hand, that the container produced therefrom can be securely and automatically closed, is secured against unintentional opening, and is ruggedly constructed. According to the invention, the blank can be formed in one piece.
[0013] In a further advantageous embodiment of the blank according to the invention, at least one second reinforcing element can be arranged at the end of the first reinforcing element opposite the inner flap. This advantageously results in further reinforcement of this area of the container produced by the blank according to the invention, or of the lid construction in this area.
[0014] In further advantageous embodiments of the blank according to the invention, at least one pressure tab can be formed in the front cover flap, wherein at least one recess for receiving the locking tab is formed in the inner flap when the blank is folded. The pressure tab serves to easily open the locking tab or to release the locking tab from the aforementioned recess. In addition, the recess for receiving the locking tab can be formed entirely in the inner flap or in the inner flap and the first reinforcing element. Furthermore, it is possible for the recess for receiving the locking tab to be formed entirely in the inner flap or in the inner flap and the first reinforcing element, and for the locking tab to be formed as an element of an intermediate flap hinged to the front wall via the bending line.
[0015] In a further advantageous embodiment of the blank according to the invention, at least one third reinforcing element can be hinged via a bending line at the end of the intermediate flap opposite the front wall. Furthermore, it is possible for at least one engagement recess or opening to be formed at the end of the intermediate flap opposite the front wall. The third reinforcing element allows for a stable design and thus improved load-bearing capacity of the intermediate flap in the folded state.
[0016] In further advantageous embodiments of the blank according to the invention, an outline of the locking tab is defined by a cut or perforation line formed in the intermediate tab and the bending line connecting the ends of the cut or perforation line. However, it is also possible for an outline of the locking tab to be defined by a cut or perforation line formed in the intermediate tab and the bending line connecting the ends of the cut or perforation line, and for the cut or perforation line to be surrounded by a further cut or perforation line to form a gap between the cut or perforation line and the intermediate tab. This ensures, on the one hand, the simple and cost-effective production of the locking tab and, on the other hand, the mobility of the locking tab through the design of the aforementioned gap.
[0017] Further advantages and embodiments of the blank according to the second aspect of the invention can be found in the description of the first aspect of the invention.
[0018] Further features of the invention emerge from the claims, the exemplary embodiments, and the drawings. The features and combinations of features mentioned above in the description, as well as the features and combinations of features mentioned below in the exemplary embodiments, can be used not only in the respective combinations specified, but also in other combinations without departing from the scope of the invention. They show: Figure 1 shows a schematic side view of a container according to the invention in a closed state; Figure 2 shows a schematic side view of the container according to Figure 1a in an open state; and Figure 3 shows a schematic representation of a blank according to the invention.
[0019] The Figure 1shows a schematic side view of a container 10 in the closed state. Figure 2 shows the container 10 in the open state. The Fig. 1 and 2 are described in summary below, wherein the same reference numerals in the figures designate the same features of the container 10.
[0020] The one in the Fig. 1 and 2 The container 10 shown is used for storing goods. It is a folding cardboard box. The container 10 comprises a front wall 12 and a rear wall 14, side walls 16, 18 connecting the front and rear walls 12, 14, as well as a bottom wall 20 and a lid structure 22. It can be seen that the lid structure 22 is hinged to an end of the rear wall 14 opposite the bottom wall 20 via a bending line 86.
[0021] Furthermore, it is clear that two pressure tabs 118, 120 are formed in a front lid flap 36 of the lid construction 22. The pressure tabs 118, 120 are formed by means of the cut or perforation lines 122, 124. By exerting pressure towards the interior of the container 10 (see arrows shown), corresponding locking tabs 58, 60 can be released from their locking engagement with recesses 76, 78 formed in the lid construction 22 (see also Fig. 2 ).
[0022] Furthermore, it can be seen from the figures that the lid construction 22 has an upper lid element 34 hinged to the end of the rear wall 14 opposite the base wall 20 via the bending line 86. Furthermore, the lid construction 22 comprises the front lid flap 36 formed on the end of the upper lid element 34 opposite the rear wall 14, as well as side flaps 40, 42 that laterally close the lid construction 22. The side flaps 40, 42 are connected, in particular glued, to dust and closure flaps 44, 46 hinged to the front lid flap 36. It can also be seen that an inner flap 38 is hinged to the end of the front lid flap 36 opposite the upper lid element 34 in such a way that it at least partially rests against an inner side of the front lid flap 36 and is connected, in particular glued, thereto.Recesses 76, 78 for receiving locking tabs 58, 60 are formed in the inner flap 38. According to the illustrated embodiment, the recess 76, 78 is formed in the inner flap 38 and a first reinforcing element 32 and is connected to one another via a connecting section 132. In the illustrated embodiment, an edge flap 48 is also formed between the front cover flap 36 and the inner flap 38.
[0023] From the Fig. 1 and 2 The arrangement of the pressure tabs 118, 120 in the area of the recesses 76, 78 also becomes clear. The pressure tabs 118, 120 are arranged in such a way that, when appropriate pressure is applied toward the interior of the container 10, they push the locking tabs 58, 60 out of the recesses 76, 78.
[0024] Furthermore, it can be seen that the inner flap 38 is articulated at the end of the front lid flap 36 opposite the upper lid element 34, such that the inner flap 38 rests against and / or is connected to an inner side of the front lid flap 36. A first reinforcing element 32 is in turn articulated to the inner flap 38, such that the first reinforcing element 32 rests against and / or is connected to an inner side of the upper lid element 34. In particular, the first reinforcing element 32 is glued to the inside of the upper lid element 34. Furthermore, it can be seen that a second reinforcing element 70 is articulated via a bending line 98 at the end of the first reinforcing element 32 opposite the inner flap 38, such that it rests on and / or is connected to the first reinforcing element 32. In particular, the second reinforcing element 70 is glued to the first reinforcing element 32.
[0025] Furthermore, it can be seen that the locking tabs 58, 60 are designed as elements of an intermediate tab 50. The intermediate tab 50 is hinged to the front wall 12 via a bending line 80. The same applies to the locking tabs 58, 60, which are also hinged to the end of the front wall 12 opposite the bottom wall 20 via the bending line 80. It is clear that the locking tabs 58, 60 are designed such that they rest against the outer side of the front wall 12 or protrude outward from the container 10. Two lateral gaps 62, 64 are formed between the locking tabs 58, 60 and the intermediate tab 50. When the container 10 is closed, the locking tabs 58, 60 securely engage in the recesses 76, 78 of the lid structure 22.
[0026] From the Fig. 2It is also clear that the intermediate flap 50 serves as an additional cover for the interior of the container 10. It can be seen that a third reinforcing element 52 is hinged to the end of the intermediate flap 50 opposite the front wall 12, such that the third reinforcing element 52 at least partially abuts and / or is connected to an inner side of the intermediate flap 50. In particular, the third reinforcing element 52 is at least partially glued to the intermediate flap 50. This significantly increases the overall stability and load-bearing capacity of the intermediate flap 50.
[0027] The lid structure 22 is also designed such that, when the container 10 is closed, an inner side of the upper lid element 34 forming the end of the lid structure 22 rests at least partially on an end of the side walls 16, 18 and / or the front wall 12 opposite the bottom wall 20. This ensures secure closure of the container 10 by means of the lid structure 22. It can also be seen that the front lid flap 36 is connected to an edge flap 48 via a bending line 92. The edge flap 48 is connected to the inner flap 38 via a further bending line 94 running parallel to the bending line 92.
[0028] Fig. 3 shows a schematic representation of a blank 130 for producing the container 10 according to the Fig. 1 and 2shown embodiment. One can see the one-piece design of the blank 130, which comprises a front wall 12 and a rear wall 14. Furthermore, one can see that the blank 130 has a bottom wall 20 and a lid structure 22, wherein the lid structure 22 is hinged to the rear wall 14 via a bending line 86. It is clear that at the end of the front wall 12 opposite the bottom wall 20, two locking tabs 58, 60 are hinged via a bending line 80, wherein the locking tabs 58, 60 are designed as elements of an intermediate tab 50 hinged to the front wall 12 via the bending line 80. The outlines of the locking tabs 58, 60 are defined by a cut or perforation line 66, 68 formed in the intermediate tab 50 and the bending line 80 connecting the ends of the cut or perforation line 66, 68.Furthermore, the cutting or perforation lines 66, 68 are each surrounded by a further cutting or perforation line 126, whereby a gap 62, 64 is formed between the cutting and perforation line 66, 68 and the intermediate flap 50.
[0029] Furthermore, it can be seen that a flat reinforcement element 52 is articulated via a bending line 104 at the end of the intermediate plate 50 opposite the front wall 12.
[0030] The lid construction 22 comprises an upper lid element 34 hinged to the end of the rear wall 14 opposite the base wall 20 via the bending line 86 and a front lid flap 36 formed at the end of the upper lid element 34 opposite the rear wall 14, as well as side flaps 40, 42 that laterally close the lid construction 22 when the container 10 is folded. The upper lid element 34 is connected to the front lid flap 36 via a bending line 90. The front lid flap 36 is in turn connected to an edge flap 48 via a bending line 92 that runs parallel to the bending line 90. The edge flap 48 is connected to an inner flap 38 by a bending line 94 that runs parallel to the bending line 92. The side flaps 40, 42 are in turn connected to the upper lid element 34 via bending lines 114, 114'.At the end of the inner flap 38 opposite the front lid flap 36, a first reinforcing element 32 is articulated via a bending line 96. It can be seen that at the end of the first reinforcing element 32 opposite the inner flap 38, a further, second reinforcing element 70 is articulated via a bending line 98. Furthermore, it is clear that two recesses 76, 78 are formed in the inner flap 38 for receiving the locking tabs 58, 60 in the folded state of the blank 130. In the illustrated embodiment, the recesses 76, 78 are connected via an intermediate section 132 and form a common recess. The outline of the recesses 76, 78 and the intermediate section 132 is defined by a cutting line 128, wherein the cutting line 128 runs in the inner flap 38 and the first reinforcing element 32.
[0031] The lid construction 22 also includes two dust and closure flaps 44, 46, which are hinged to opposite ends of the front lid flap 36 via corresponding bending lines 116, 116'. It can be seen that two pressure flaps 118, 120 are formed in the front lid flap 36. The pressure flaps 118, 120 are formed via corresponding cutting or perforation lines 122, 124, which define the outline or shape of the respective pressure flap 118, 120.
[0032] Furthermore, it is clear that the rear wall 14 is connected to the side wall 18 via a bending line 112, and the side wall 16 is connected to the rear wall 14 via a bending line 110. On the bottom wall 20, an adhesive tab 24, 26 is arranged laterally along corresponding bending lines 106, 108. Furthermore, it can be seen that the front wall 12 also has laterally arranged adhesive tabs 28, 30, which are connected to the front wall 12 via corresponding bending lines 100, 102. In addition, openings 54, 56 are formed in the front wall 12 in an upper region opposite the bottom wall 20. In the folded state of the blank 130, the openings 54, 56 serve to extend the path of movement of the locking tabs 58, 60. The outline of the openings 54, 56 is defined by corresponding cutting lines 72, 74 in the front wall 12.
[0033] Furthermore, it can be seen that the intermediate plate 50 is connected to a third reinforcing element 52 via a bending line 104.
[0034] The described container 10, as well as the blank 130 used to produce the container 10, are typically made of cardboard, paper, or plastic. Other suitable materials are also conceivable.
