Description

[0001] The present invention relates to a blank for manufacturing the container. The present invention further relates to a container made of paper, cardboard, corrugated board or the like for holding goods, comprising a bottom wall, a lid wall and side walls connecting the bottom and lid walls to form a receiving space for holding the goods.

[0002] Containers, in particular packaging containers and blanks for the manufacture of containers of the type mentioned above, are known in great variety. Comparable containers are known, for example, from CN 2 21 829 622 U and JP 2007-50 920 A. Furthermore, DE 20 305 912 U1 describes a tray-like container made of cardboard, paper, or the like, wherein the container is manufactured from a single blank and has a base defined by bend lines with side surfaces integrally connected via the bend lines to form a receiving space for goods. Subdivisions of the receiving space are not provided here. However, it is also known that such receiving spaces can be further subdivided by means of separately manufactured inserts. Such inserts are usually made of paper or cardboard.A disadvantage of these known containers, however, is that at least two separate elements are required for their manufacture to create subdivisions within the storage space. An additional lid element would also have to be manufactured separately. Furthermore, the shape of these known containers often presents difficulties when stacking and storing multiple containers.

[0003] It is therefore an object of the present invention to provide a blank of the type mentioned above and a container which are easy and inexpensive to manufacture, wherein the container should also have improved stackability.

[0004] The stated problems are solved by a blank with the features of claim 1, by a container with the features of claim 8, and by a set with the features of claim 13. Advantageous embodiments of the container, the blank, and the set according to the invention are described in the respective dependent claims. Advantageous embodiments of the blank are to be considered advantageous embodiments of the container, and vice versa. The same applies to advantageous embodiments of the set.

[0005] A first aspect of the invention relates to a blank made of paper, cardboard, or corrugated board for manufacturing a container comprising a bottom wall, wherein the bottom wall has a central bottom wall and side bottom walls hinged to it at opposite ends. The blank also comprises a lid wall comprising a central lid wall and side lid walls hinged to it at opposite ends, as well as a first side wall for hingedly connecting the bottom wall to the lid wall, and a second side wall hinged to the end of the bottom wall opposite the first side wall. At least two inner walls are connected to the second side wall and to each other via bend lines running parallel to each other, and in the folded state of the blank divide a receiving space of the container into at least two compartments. In particular, the blank is formed in one piece.This allows for cost-effective production of the blank and the resulting container. The intended compartments within the container allow for the advantageous storage of different types of goods in separate sections, providing a practical and attractive solution for product sales. Using an integrated partition, meaning one-piece construction with the other container elements, simplifies manufacturing and eliminates the need for additional parts, thus saving costs and reducing environmental impact.

[0006] In further advantageous embodiments of the blank according to the invention, at least four inner walls are formed, wherein the first inner wall, hinged to the second side wall, rests against an inner surface of the side cover wall when the blank is folded; the second inner wall, hinged to the first inner wall, projects into the receiving space when the blank is folded and subdivides it; the third inner wall, hinged to the second inner wall, rests against an inner surface of the middle bottom wall when the blank is folded; and the fourth inner wall, hinged to the third inner wall, projects into the receiving space when the blank is folded and further subdivides it. It is also possible that at least one adhesive tab is hinged to the side of the fourth inner wall opposite the third inner wall via a bending line.This design and arrangement of the inner walls allows them to be formed as a single unit with the other elements of the container, which in turn simplifies and reduces the cost of manufacturing both the blank and the finished container. Such a construction avoids the need for additional parts, which saves costs and reduces environmental impact.

[0007] In further advantageous embodiments of the blank according to the invention, a front and a rear closing flap are hinged to opposite sides of the central bottom wall for lateral closure of the receiving space when the blank is folded. Furthermore, the front closing flap may comprise a front central flap and lateral flaps hinged to it, and the rear closing flap may comprise a rear central flap and lateral flaps hinged to it, with the front and rear lateral flaps projecting obliquely from the front central or rear central flap, respectively. It is also possible for the closing flaps to have identical surface shape and size. This design of the closing flaps results in improved stability of the resulting container.Furthermore, the container can be closed easily and securely. Finally, the stackability of the resulting container is also improved, since the bottom wall and the lid wall follow the outer shape or circumference of the locking tabs and together form a recess into which another container, produced from the blank according to the invention, can be inserted, so that both containers are aligned in a saddle-like manner with respect to each other.

[0008] The container can be made from cardboard, corrugated board, paper, or a combination of these materials. In particular, the use of cardboard and / or paper contributes to a sustainable, resource-efficient, and therefore ecologically desirable production process. This allows for the largely or entirely avoidable use of plastic.

[0009] A second aspect of the invention relates to a container for storing goods manufactured using a blank according to the first aspect of the invention. The container consists of paper, cardboard, or corrugated board and comprises a bottom wall, a lid wall, and side walls connecting the bottom and lid walls to form a receiving space for the goods. The bottom wall comprises a central bottom wall and side bottom walls hinged to it at opposite ends, the side bottom walls each extending at an angle from the bottom wall towards the lid wall. The lid wall comprises a central lid wall and side lid walls hinged to it at opposite ends. The central bottom and lid walls, as well as the side bottom and lid walls, are arranged parallel to each other.The technical advantages of the container according to the invention lie in the fact that the container can be manufactured from environmentally friendly and cost-effective materials such as paper, cardboard, or corrugated board. Due to its novel shape, the container's design allows for improved stackability, enabling multiple containers to be stacked on top of each other in a space-saving manner.

[0010] In a further advantageous embodiment of the container according to the invention, the container has a front and a rear closing flap, which serve to close the receiving chamber laterally. These closing flaps have identical surface shape and size. In other words, the container is provided with two flaps for closing the receiving chamber laterally, both of which have the same shape and size.

[0011] This arrangement offers several technical advantages. Firstly, the identical shape and size of the surfaces allow for simple and precise assembly of the locking tabs, which in turn simplifies and reduces the cost of the container's manufacturing process. Secondly, the side locking mechanism improves the container's structural properties.

[0012] In a further advantageous embodiment of the container according to the invention, the container's receiving space is divided into at least two, and in particular three, compartments by means of corresponding internal walls. In other words, the invention relates to a container that is a one-piece box with integrated partitions. The partitions divide the interior into several separate compartments. The internal walls can be articulated to one another via bending lines, and the compartments are formed by a predetermined folding within the receiving space. Advantageously, different types of goods can thus be stored in separate compartments, which represents a practical and attractive solution for product sales.By using an integrated partition, meaning one that is integrally connected to the other elements of the container, container manufacturing is simplified and the need for additional parts is avoided, which in turn saves costs and reduces environmental impact. Overall, this invention offers a cost-effective yet efficient solution for manufacturing containers from paper, cardboard, or corrugated board, enabling improved stackability and organization of goods.

[0013] In a further advantageous embodiment of the container according to the invention, the container is designed in a saddle shape when viewed in the direction of the front and / or rear closing flap, with the lid wall having a saddle recess for receiving another saddle-shaped container. In other words, the container is designed in such a way that the lid wall forms a recess into which another container can be inserted, so that both containers are aligned in a saddle shape relative to each other. The side walls of the bottom may extend from the bottom wall at an angle of between 10° and 80° towards the lid wall. Angles between 10° and 80° are understood to include, in particular, the following angles: 10°, 15°, 20°, 25°, 30°, 35°, 40°, 45°, 50°, 55°, 60°, 65°, 70°, 75°, 80°. However, intermediate values ​​between the specified angles are also conceivable.This container design offers several advantages. Firstly, the saddle shape improves stackability, as the recess in the lid allows the containers to be securely placed on top of each other. Secondly, the saddle shape provides a space-saving solution for transporting and storing containers, as one container can be nested inside another for a more compact form. Overall, this container design offers numerous benefits in terms of stackability, flexibility in combining products or packaging, space-saving storage, and cost-effective manufacturing.

[0014] In a further advantageous embodiment of the container according to the invention, it is provided that the container is manufactured from a single piece. This enables cost-effective production of the container.

[0015] In a further advantageous embodiment of the container according to the invention, the front and rear locking flaps each have at least one locking tab that serves to engage with receiving openings arranged in the bottom and top walls. In other words, the container's locking flaps are equipped with specific locking tabs that can be engaged in special openings in the bottom and top walls. This arrangement enables a secure and reliable closure of the container, thereby preventing accidental opening during transport or storage.

[0016] Further features and their advantages can be found in the descriptions of the first aspect of the invention, whereby advantageous embodiments of the first aspect of the invention are to be regarded as advantageous embodiments of the second aspect of the invention and vice versa.

[0017] A third aspect of the invention relates to a set comprising at least two stackable containers according to the second aspect of the invention. The set may include at least one pedestal-like base element for storing and stacking the containers.

[0018] The individual features and their advantages of the third aspect of the invention can be found in the descriptions of the second aspect of the invention, whereby advantageous embodiments of the second aspect of the invention are to be regarded as advantageous embodiments of the third aspect of the invention and vice versa.
