Description

Packaging for a windshield wiper blade State of the art The present invention relates to packaging for a windshield wiper blade. From the state of the art, windshield wiper blade packaging is known to consist of a box and an insert piece, the latter being designed to house a wiper blade and insert it into the box. In the state of the art, these boxes are usually designed in such a way that, once packaged, the insert piece and the brush are completely enclosed. In addition, there are blister packs, in which the brush, for example, is completely surrounded by a transparent plastic material. There are also blister packs in which one side of the packaging is made of cardboard and the other sides of a transparent plastic material. Disclosure of the invention The present invention proposes a packaging for a windshield wiper blade, wherein the wiper blade may be, in particular, a wiper for a vehicle window (e.g., for a rear window or windshield). The wiper blade is, for example, a wiper blade consisting of a spring guide and a wiper blade and, if applicable, other components. The packaging consists of a box with at least one viewing window and an insert (also called a "tray"), where the viewing window is made of a cellulosic material that is at least partially transparent and closes the opening of the box. For this purpose, the viewing window is attached to the box using an adhesive, for example. The shape of the viewing opening in the housing is determined by the required rigidity of the housing and the desired visibility of the brush through the viewing opening. The required rigidity is determined, for example, by a minimum housing stiffness necessary for assembly during a mechanical and / or manual processing stage. It should be noted that the necessary rigidity of the case can be provided entirely by the case itself or in combination with the viewing window when it is mounted on the case. The necessary rigidity of the box can be achieved, for example, by a suitable determination of an opening surface and / or a shape and / or a position of arrangement and / or a distance of the viewing opening from the respective edges of the box. Furthermore, the box is designed as a support frame for the viewing window, so the viewing window does not have to be self-supporting and can be flexible in terms of thickness and / or rigidity. The insert has external dimensions that essentially correspond to the internal volume of the housing. Furthermore, the insert is designed to accommodate the windshield wiper blade by means of an internal shape that matches the blade's shape, and to be inserted into the housing along with the blade. The windshield wiper blade packaging described in the present invention offers the special advantage that, thanks to the use of a cellulosic material that is at least partially transparent for the viewing window, it allows for particularly environmentally friendly disposal of at least the viewing window due to its biodegradability, while at the same time allowing a view of at least part of the windshield wiper blade housed within the packaging. It is particularly advantageous that the entire packaging, or at least a large part of it, is made of biodegradable materials, thus providing a complete and particularly environmentally friendly windshield wiper blade package. By designing the box as a support frame for the viewing window, a particularly high flexibility is achieved in the design of the viewing window, which may exhibit lower rigidity due to the cellulosic material, so the viewing window itself cannot contribute to the overall stability of the packaging or can only do so to a lesser extent. The sub-claims show preferred developments of the invention. Cardboard and / or natural fiber-based boxes are particularly advantageous for enabling environmentally friendly packaging disposal. Furthermore, the box is preferably designed as a folding box and / or as a die-cut piece with an adhesive tab. The box is also preferably designed in the shape of a rectangular prism when assembled. The minimum rigidity of the box, as described above, is especially important for folding boxes, as it ensures that the box can be positioned, for example, in the rectangular prism shape, quickly enough and / or with minimal deformation during manufacturing. In other words, adequate minimum rigidity allows the box to be reliably unfolded manually and / or automatically into the desired shape. In an advantageous embodiment of the present invention, the distance between the edges of the box and the viewing opening is at least 0.5 cm, preferably 1 cm, and more preferably 1.5 cm. This ensures, among other things, the function of the box as a support frame for the viewing window and / or the rigidity required for mounting the box. In another advantageous configuration of the present invention, the viewing opening comprises at least a first viewing opening and a second viewing opening adjacent to the first viewing opening, the two viewing openings being separated from each other by a bridge provided in the housing. In this case, the bridge advantageously has a predefined minimum width, which is determined based on the required rigidity of the housing and / or packaging. The use of adjacent viewing windows thus allows for improved overall visibility of the windshield wiper within the packaging, while maintaining the housing's function as a support frame. It should be noted that, in such a case, the viewing window can be a single window covering both viewing openings. Alternatively, it is also possible to close each viewing opening with an individually manufactured viewing window. The width of the bridge between adjacent viewing openings is at least 0.5 cm, preferably at least 1 cm, and even more preferably at least 1.5 cm. Furthermore, the bridge can be further reinforced, preferably inside the enclosure, with a material from the enclosure and / or a different material. Packaging is particularly preferred in which the wiper blade is packed in a pre-tensioned state of a wiper blade spring rail and / or secured by a rigid box such that the forces acting on the box, in particular the forces generated by the pre-tensioned state of the spring rail, between 10 N and 20 N, preferably between 14 N and 18 N, do not cause essentially any visible deformation of the packaging from the outside. Deformation essentially not visible from the outside means that the box may undergo minor deformations, for example, bulging of the side surfaces, which do not affect the basic stability of the packaging and / or influence the optical requirements of the packaging only within a permissible range and / or do not adversely affect the stackability and / or transportability, etc., of the packaging.For example, an acceptable deformation of the packaging may include bulging of one or more sides of up to 2 mm, preferably up to 1 mm and, even more preferably, up to 0.5 mm, without this implying a limitation to the values ​​mentioned. In another advantageous embodiment of the present invention, the box and / or the viewing window and / or the insert and / or an adhesive for assembling the box and / or an adhesive for fixing the viewing window in the viewing opening area are made of biodegradable materials. In a particularly advantageous embodiment, all the aforementioned packaging components are made of biodegradable materials, so that the packaging as a whole can be advantageously disposed of as compost without having to separate the individual components beforehand. It is advantageous for the length of the box to be between 55 cm and 100 cm, without being limited to that length. It is also advantageous for the length of the viewing opening to be between 5 cm and 30 cm, preferably between 10 cm and 25 cm, and even more preferably between 18 cm and 22 cm. Alternatively or additionally, a width of the viewing opening of between 1 cm and 5 cm is preferred, preferably between 2 cm and 4 cm, and even more preferably between 2.5 cm and 3.5 cm. The above values ​​for the length and width of the viewing opening allow for particularly advantageous overall stability of the packaging and sufficient visibility of the packaged brush. Brief description of the drawings The following describes in detail examples of embodiments of the invention with reference to the accompanying drawings. In the drawing: Figure 1 shows a first example of a packaging for a windshield wiper blade according to the invention; Figure 2 shows a second example of a packaging for a windshield wiper blade according to the invention; and Figure 3 shows an example of an embodiment of a packaging box according to the invention in combination with two viewing windows. Ways of realizing the invention Figure 1 shows a first example of a packaging according to the invention for a wiper blade 10 and, in particular, for a wiper blade for a windshield and / or rear window of a vehicle, which may be, for example, a car or a truck. The packaging comprises a cardboard box 20 with a viewing opening 22, a viewing window 30, and an insert piece 40, wherein the viewing window 30 is made of a transparent cellulose material and closes the viewing opening 22 of the cardboard box 20. For this purpose, the viewing window 30 is attached to the cardboard box 20 by means of an adhesive (not shown), which is applied during the manufacturing of the packaging to the inside of the cardboard box 20 around the opening 22 to secure the viewing window 30 to the inside of the cardboard box 20. The cardboard box 20, which is preferably a folding box, is designed as a support frame for the viewing window 30, wherein the distance from the viewing opening 22 to the respective edges of the cardboard box 20 in this embodiment is 1 cm, to ensure the necessary stability or rigidity of the cardboard box 20. The length of the viewing opening 22 corresponds to 20 cm, while the width of the viewing opening 22 corresponds to 3 cm. The length of the cardboard box 20 corresponds to 55 cm. The insert piece 40, made of biofiber material, has external dimensions that essentially correspond to the internal volume of cardboard box 20. Furthermore, the insert piece 40 is designed to accommodate brush 10 by means of an internal shape that matches brush 10, and to be inserted together with brush 10 into cardboard box 20. Based on the configuration described above, the packaging of brush 10 is designed as biodegradable packaging, allowing for particularly environmentally friendly disposal. Figure 2 shows a second example of a packaging according to the invention for a windshield wiper blade 10. In comparison with the first embodiment shown in Figure 1, the box 20, which is also designed here as a cardboard box, has a first viewing opening 22 and a second viewing opening 24 arranged adjacent to the first viewing opening 22, both viewing openings 22, 24 being separated by a bridge 26 provided in the box 20, which has an example width of 1.5 cm. The viewing openings 22, 24 are closed by a continuous viewing window 30 inside the box 20, which is made of transparent cellulosic material. Furthermore, Figure 2 shows a brush 10, which is inserted into the housing 20 by means of an insert (not shown). The brush 10 has a spring rail, which is housed in the packaging in a pre-tensioned state. Since the brush 10 is inserted into the housing 20 from the side, corresponding pressure forces 60 are exerted on the insert and the housing 20, which could cause lateral deformation of the housing 20. However, this deformation is counteracted by maintaining the necessary rigidity of the housing 20. Figure 3 shows an example of embodiment of a box 20 of the packaging of the invention in combination with two viewing windows 22, 24, in which separate viewing windows 30 of a transparent cellulosic material have been glued respectively and are separated by a bridge 26 from the box 20 to increase the stability of the box 20. Box 20, which is designed as a folding box, is shown here in a state where Box 20 has been die-cut from a sheet of cardboard and is in an unassembled state. Next, the opposite sides of box 20 are glued together by means of an adhesive tab 50, and box 20 is unfolded to form a solid rectangular body, so that it can accommodate an insert piece 40 with an inserted brush 10, as shown in Figure 1.
