Description

[0001] The invention relates to a packaging made of folding material, for example corrugated cardboard, which can be produced from a blank by folding, bending and joining, preferably by gluing, with an inner contour that is approximately form-fitting to the packaged goods, preferably for sensitive and / or round packaged goods.

[0002] The invention relates to a one-piece packaging, wherein the inner contour of the packaging is designed to almost form-fittingly enclose the product and thus provide support and protection. It lies in the technical field of packaging technologies, with a focus on product protection and convenience.

[0003] Current technology does not allow for a one-piece package that can be filled and sealed by machine and has an inner part that securely holds the product. Existing packaging, for example for frozen cakes, consists of a corrugated cardboard or solid board box, in some versions additionally with a packaging aid made of EPS (expanded polystyrene) that has a rectangular outer contour and a cylindrical inner contour. This "cake ring" has to be manually placed over the cakes during packaging before the cake, with the EPS ring, can be mechanically inserted into the packaging and the box sealed.This two-part construction consists of two materials that consumers must dispose of separately. The cake ring is made of plastic, which is viewed critically as a packaging material and is subject to increasing legal restrictions. A further disadvantage is that the cake rings have a large transport and storage volume. Without this cake ring, simple corrugated or solid cardboard packaging can be erected, filled, and sealed by machine. However, non-square items, such as round ones, can shift and be damaged during transport in a square package. Furthermore, the EPS cake ring increases the load-bearing capacity of the packaging, which is particularly important for product protection, especially for items that are not intended to bear weight.

[0004] The object of this invention was therefore a construction that can be delivered and stored flat, that can be filled, erected and closed by machine, that consists of a one-piece blank which fixes the, preferably but not exclusively, round and / or sensitive goods in the packaging in an almost form-fitting manner, whereby easy handling when removing the goods, tamper protection and good stacking or load-bearing capacity must also be ensured.

[0005] The invention consists of a one-piece blank that is transported and stored flat and is only erected during filling and sealing. The form-fitting enclosure is divided into two parts (3), allowing the goods to be mechanically placed centrally on the base (1) of the packaging and then the inner contour to be folded around the goods (cf. Fig. 2 to Fig. 3) This invention is not only machine-erectable and sealable, but also fillable. Furthermore, the internal structure increases the stability of the packaging without increasing its external dimensions. The preferably square outer contour allows for easy stacking. The proportions of both the internal and external contours are determined by the dimensions of the product being packaged. The design of the internal contour can be adapted to the shape of many products and is therefore not limited to round items. To remove the product, the flap on the lid must first be opened, and the packaging then broken / folded apart before the product can be removed. This also ensures tamper protection. Since opening the packaging exposes half of the product, it can, if desired, slide out of the packaging without being touched.

[0006] The packaging is explained below using exemplary embodiments. Reference is made to the drawings, which show the following: Fig. 1 the inside of the flat-lying blank of an embodiment of the invention for a cylindrical packaged item Fig. 2 an embodiment of the invention for a cylindrical packaged item with an already formed inner contour by connecting the fastening tab (10) with the tab (6) Fig. 3 an embodiment of the invention for a cylindrical packaged item with a formed inner contour that rests on the bottom part (1) Fig. 4 An upright embodiment of the invention for a cylindrical package with an unsealed lid Fig. 5 an embodiment of the invention for a cylindrical package in a completely closed and already opened state as intended

[0007] In Fig. Figure 1 shows the various surfaces comprising the invention, the sizes and proportions of which may differ for other application examples. The various lines are also shown, with the outer contour, as well as some other lines, being dividing lines (13). Furthermore, crease and / or fold lines (12) and separable lines (11) are used. These separable lines (11) are designed to hold the two adjacent surfaces together, but allow the two surfaces to separate when the packaging is opened.

[0008] The invention consists, as described in Fig. As shown in Figure 1, the package consists of a base surface (1) and a lid surface (7), which are connected to each other via a side surface (5). The lid also has three surfaces (8, 9) for closing the packaging, for example, by gluing. In addition to the side surface (5), the base has a side surface (4) opposite the side surface (5), as well as two side surfaces (2). Each of the side surfaces (2) has the inner contour-forming side part (3) opposite the base surface (1), and a tab (6) on each of the other two sides. In this embodiment, the tab (6) and the fastening tab (10), which is attached to the inner contour-forming side part (3), are shaped such that their outer edges are congruent when the inner contour is correctly formed.In other embodiments, the tab (6) can also be shortened, whereby the tab (6) and the fastening tab (10) are each attached separately to the side part (5).

[0009] This can be, as in Fig. As can be seen in Figure 2, the inner contour is formed by connecting the fastening tab (10) and the tab (6) together, for example by gluing. Subsequently, these two inner contours can be folded or bent over along the crease and / or fold line (12) between the base (1) and the side panel (2), onto the base, as shown in Figure 2. Fig. 3. The packaged goods that were previously placed on the floor are enclosed.

[0010] The fixed outer contour can then be achieved by attaching the side parts (4, 5) to the tabs (6). This can be seen in Fig. 4. Next, the lid must be folded or creased onto the packaging and the lid closure flaps (8, 9) must be attached to the packaging, for example by gluing them to the side parts (2, 4).

[0011] To open the packaging, a portion of the lid must first be opened by grasping the opening mechanism (14). The packaging can then be separated along the separable lines (11) and unfolded over the fold and / or crease line (12) in the base (1). In this embodiment, these separable lines (11) run centrally across the side panels (5, 4), the lid closure flap (9), and in an arc over the lid (7). However, the position of these fold and / or crease lines (12) and separable lines (11) can be arbitrarily chosen, and an asymmetrical position may be advantageous depending on the shape of the packaged goods. When fully opened, as shown in Fig.As can be seen in step 5, in this application example half of the packaged goods are exposed and can therefore be easily removed.

[0012] The invention is a single-piece design, thus saving on transport and logistics costs. It can be filled, erected, and sealed by machine and simultaneously provides a form-fitting hold for the packaged goods. Furthermore, the packaging offers tamper protection, easy removal of contents, and greater stability than comparable packaging without a form-fitting inner contour.
