Description

[0001] The invention relates to a folding packaging for a tool, in particular for a sharp-edged tool such as a saw blade.

[0002] Packaging for saw blades or sharp-edged tools in general is a familiar concept. While typically used as retail packaging, it can also serve a purpose beyond sales by simultaneously acting as storage containers. For example, such packaging containing various tools can be placed on a shelf, perhaps in a tradesman's van, allowing the necessary tool for a specific task to be easily retrieved. When a different tool is needed, the previously used one is returned to its packaging. The tools can also be sharpened while still in their packaging.

[0003] A problem with this type of packaging is the risk of injury. With existing packaging, the sharp-edged tools are difficult to grip. The tool usually has to be held by its sharp edge. To prevent injuries, the sharp edges or saw teeth are now often covered with a disposable plastic protector.

[0004] It is an object of the present invention to propose a folding packaging that is easy to manufacture and has a low risk of injury.

[0005] This problem is solved by a folding packaging with the features of claim 1. Advantageous further developments are the subject of the dependent claims and will become apparent from the description and the drawings.

[0006] The folding packaging according to the invention serves as folding packaging for a tool, in particular for a sharp-edged tool. Sharp-edged tools can be, in particular, saw blades, such as round saw blades for a circular saw.The folding packaging comprises an outer packaging body with a back wall section, a front wall section, a closure section, a first side wall section connecting the back wall section to the front wall section, and a second side wall section connecting the back wall section to the closure section, wherein the back wall section and the front wall section are configured to define a receiving space between them, and wherein the closure section is detachably connected to the front wall section in order to open or close an access opening to the receiving space, and an insert for placement in the receiving space, which has a protective section that can be folded down about a fold line and a receiving area for the tool, wherein the protective section has a protective edge surrounding the receiving area at least towards the access opening.The insert is movable between a retracted position, in which it is completely located within the receiving space, and a protruding position, in which the protective section protrudes at least partially from the receiving space through the access opening.

[0007] The outer packaging body refers specifically to the outer part of the folding packaging, which forms the casing for the insert. In the outer packaging body, which is a single piece, the individual sections—back panel, front panel, closure panel, and side panels—are separated from each other by fold lines. When folded, the outer packaging body can be rectangular or square.

[0008] When the outer packaging body is folded, the receiving space is present within it and is bounded by at least the rear and front wall sections. The access opening allows the insert to be pulled or pushed from the retracted position to the protruding position using the tool after the closure section has been released from the front wall section.

[0009] The protective rim surrounds the tool, at least in the direction of the access opening. This means that after opening the package and reaching into the access opening, the protective rim prevents contact with the sharp edge of the tool, thus reducing the risk of injury as much as possible. Since the protective rim is part of the insert, no additional measures are needed to cover the sharp edge of the tool. The protective rim is therefore already integrated into the folding packaging.

[0010] However, if the insert is in the protruding position, the protective section can be folded down, particularly towards the back panel, along the fold line. This exposes the tool on the access side. The tool, which now protrudes slightly from the outer packaging, can then be grasped and removed safely by its sides, without having to touch its sharp edges.

[0011] The folding packaging according to the invention is relatively easy to manufacture, particularly by machine, thus saving costs. Furthermore, the folding packaging is sustainable because it is reusable and resource-efficient. Nevertheless, an attractive, high-quality appearance can be achieved. The risk of injury when removing tools is negligible due to the fold-down protective edge, thus ensuring safe handling.

[0012] Preferably, the insert has a front and a back, with the receiving area open towards the front and the protective section foldable towards the back. In particular, when the insert is intended to be positioned within the outer packaging, the front faces the front wall section, while the back faces the rear wall section. The receiving area can be designed to roughly correspond to the shape of the tool to be received, so that the tool is securely positioned within the receiving area, possibly with a certain amount of play. For example, the receiving area can be circular if the folding packaging is intended for a circular saw blade.

[0013] The insert can have a hinged pull tab located at the access opening when the insert is retracted. The pull tab is used to pull the insert out towards the protruding position. In particular, the pull tab can be hinged around a fold line. The front panel section can have a recess that exposes the pull tab when the insert is retracted. This ensures that the pull tab is not obscured by the front panel section, allowing it to be easily grasped.

[0014] The rear panel section or the front panel section, or both, can have a guide edge for the insert, along which the insert is guided between the retracted and protruding positions. This ensures precise guidance of the insert during its movement between the retracted and protruding positions, greatly facilitating insertion and removal.

[0015] The guide edge can have a stop that defines the protruding position. The stop is, in particular, an end stop that closes off the guide edge. When the insert rests against the stop, it is in the protruding position. Preferably, the insert has a counter-stop that rests against the stop in the protruding position.

[0016] In an advantageous embodiment, the front and rear wall sections are attached to one another, ensuring that the insert is securely positioned within the receiving space and remains there even when the closure section is detached from the front wall section. For example, the front and rear wall sections can be glued together. This can be achieved, for instance, using adhesive strips that run approximately parallel to the guide edge.

[0017] Another way to hold the front and back panels together is to use magnets. For example, magnets can be integrated into the folding packaging to create this magnetic connection. This has the advantage that the magnetic bond can also be easily broken.

[0018] The closure section and the front panel section can be detachably connected by a snap-fit ​​connection. For this purpose, either the front panel section or the closure section can have a slot, and the other section can have a snap-fit ​​tab for insertion into the slot. Preferably, the front panel section has the slot, and the closure section has the snap-fit ​​tab. The snap-fit ​​connection has the advantage of being very easy and reversible to open and close. Furthermore, the necessary components, such as the snap-fit ​​tab and slot, can be easily incorporated into the folding packaging, even during automated production.

[0019] The protective section can have a width that is at least 30%, preferably at least 40%, and particularly preferably approximately 50% of the width of the insert. This ensures that, after the protective section is folded down, a sufficiently large portion of the tool is exposed for gripping.

[0020] The outer packaging body and the insert can be made of materials such as cardboard or wood, especially birch wood.

[0021] The invention is described below by way of example with reference to an embodiment shown schematically in the drawings. Fig. 1 a perspective view of an outer packaging body in the unfolded state and an insert according to an exemplary embodiment, Fig. 2 a perspective view of the folding packaging made of Fig. 1 In the closed state, Fig. 3 shows a perspective view of the folding packaging. Fig. 1 and 2in the open state, with the insert in the inserted position, Fig. 4 shows another perspective view of the folding packaging. Figs. 1 to 3 in the open state, with the insert in the protruding position, and Fig. 5 another perspective view of the folding packaging. Figs. 1 to 4 in the open state, with the insert in the protruding position and the protective section folded down.

[0022] The folding packaging 10 according to the embodiment shown in the figures has, as Fig. 1Figure 11 illustrates a packaging body 11 and an insert 12. The packaging body 11 is a single body, made primarily of cardboard, comprising a back wall section 13, a front wall section 14, and a closure section 15. A first side wall section 16 is provided between the back wall section 13 and the front wall section 14, and a second side wall section 17 is provided between the back wall section 13 and the closure section 15. Sections 13, 14, 15, 16, and 17 are separated from adjacent sections by fold lines, around which the material of the packaging body 11 can be folded.

[0023] In Fig. 1 It can also be seen that the front wall section 14 has a insertion slot 30. The closure section 15 is provided with a corresponding insertion flap 31. If the outer packaging body 11 is folded around the fold lines, as for example in Fig. 2As shown, the tab 31 can be inserted into the slot 30 to releasably close the outer packaging body 11.

[0024] In Fig. 1 It can also be seen that the outer packaging body 11 has a protruding area on its upper and lower edges, both on the rear wall section 13 and on the front wall section 14, on which a guide edge 27 with an (end) stop 28 is provided.

[0025] Furthermore, in Fig. 1An insert 12 with a front 23 and a back 24 is shown. The insert 12 serves to receive a tool W, in particular a sharp-edged tool W, and then to store it in the closed outer packaging body 11. The insert 12 therefore has a receiving area 21 for the tool W, open towards the front 23. In this example, the receiving area 21 is designed as a recess whose shape approximately corresponds to the shape of the tool W, so that it can be received snugly, but usually with some play, in the receiving area 21. In the exemplary embodiment, the tool W is a saw blade of a circular saw, so that the receiving area 21 accordingly has a circular shape, the diameter of which is at least as large as the outer diameter of the saw blade including the saw teeth.The receiving area 21 is limited by a protective edge 20, which surrounds the outer circumference of the tool W when it is in the receiving area 21 to prevent contact with the saw teeth.

[0026] Furthermore, the insert 12 has a hinged pull tab 25 which, in this embodiment, but not necessarily, also forms part of the protective rim 20 when folded towards the receiving area 21. The pull tab 25 serves to pull the insert 12 out of the outer packaging body 11. To facilitate gripping the pull tab, a recess 26 is provided on the front wall section 14.

[0027] Figs. 2 to 5Each figure shows the outer packaging body 11 in its folded state with the insert 12 arranged within it. The front 23 of the insert 12 faces the front wall section 14, and the back 24 of the insert 12 faces the rear wall section 13. In the folded state, the rear wall section 13 and the front wall section 14 define a receiving space for the insert 12. The rear wall section 13 and the front wall section 14 adhere to each other. This can be achieved, for example, by adhesives such as adhesive strips or magnetically.

[0028] In Figs. 2 and 3 The insert 12 is fully positioned within the receiving space. This corresponds to a retracted position. Fig. 2 shows the state in which the plug-in tab 31 is inserted into the plug-in slot 30, and Fig. 3Figure 1 shows the state in which the tuck tab 31 is not inserted into the tuck slot 30, i.e., an access opening 18 of the outer packaging body 11 is open. In this state, the pull tab 25 can be grasped at the recess 26 and the insert 12 pulled out of the receiving space.

[0029] Fig. 4Figure 1 shows the insert 12 after it has been pulled from the inserted position to a protruding position. In this state, the insert 12 protrudes from the receiving space through the access opening 18, at least with a protective section 19, which in this embodiment has half the width of the entire insert 12. This protruding position is defined by the fact that counter-stops 29 formed on an upper and lower edge of the insert 12 bear against the corresponding stops 28. Once the insert 12 reaches this protruding position, it can no longer be pulled further out of the receiving space. During the movement between the protruding position and the inserted position, the insert 12 is guided by the guide edge 27.

[0030] With the insert 12 in the protruding position, the protective section 19 can be folded down along its fold line 22, i.e., towards the back side 24. This causes the corresponding part of the protective edge 20 to also fold down. This allows the protruding part of the tool W to be easily gripped from above and below without having to touch the sharp edges of the saw teeth. The saw blade can then be removed from the receiving area 21 and used. When repacking the saw blade, the operator places it back into the receiving area 21 with the protective section 19 folded down and then folds the protective section 19 back up. The insert 12 can then be pushed back into the receiving area, i.e., into the inserted position. Finally, the folding package 10 is closed using the tuck tab 31 and the slot 30.

[0031] The folding packaging 10 according to the invention can be manufactured relatively easily by machine, is reusable, and easy to use. Furthermore, the integrated protection against sharp edges ensures that the risk of injury when removing the tool W is low, without the need for additional protective measures such as disposable plastic guards. The folding packaging 10 is therefore also particularly sustainable. Reference symbol list
