[0005] The invention is based on the object of improving a packaging unit with simple constructive measures.

[0006] The problem is solved by a packaging unit, in particular a drilling tool packaging unit, for an insert tool, in particular a drilling tool, having a first means, in particular a fastening means, for fastening the packaging unit in or on a presentation device, in particular a presentation shelf or a sales shelf, and having a receiving means for receiving an insert tool, which is positively connected to the receiving means, in or on the packaging unit. The receiving means is provided to hold the insert tool in or on the packaging unit in a holding state of the packaging unit, in which the receiving means is formed integrally with the first means. According to the invention, the receiving means remains on the insert tool in a separated state, in which the receiving means is separated from the first means of the packaging unit.

[0007] The invention makes it possible to easily design a packaging unit that securely holds an insert tool and prevents it from accidentally coming loose or falling out. Furthermore, the packaging unit according to the invention enables advantageous detachment of the insert tool and the receiving means from the fastening means of the packaging unit. Furthermore, it can be provided that the insert tool and the receiving means can be detached from at least the first means of the packaging unit using only an aid, such as pliers or scissors, in order to advantageously hinder or even prevent shoplifting of such insert tools.

[0008] The receiving means according to the invention makes it possible to hold the insert tool on the packaging unit when the packaging unit is held in place, such that the insert tool is firmly connected to the packaging unit and secured against accidental release. The receiving means is further designed such that when the packaging unit is separated, the receiving means remains positively connected to the insert tool. In addition, the receiving means can be materially connected to the insert tool, in particular by means of an adhesive. Separation of the packaging occurs between the receiving means and the first means, in particular the fastening means, of the packaging unit, wherein the receiving means of the packaging unit remains positively connected or both positively and materially connected to the insert tool.

[0009] "Material bonded" is understood in particular to mean that the holding device is held together with the insert tool by atomic or molecular forces, such as during soldering, welding, gluing, and / or vulcanization. This advantageously allows a reliable and structurally simple design of the holding device to be achieved in a simple manner.

[0010] The receiving means should, in particular, be of solid construction. In particular, the receiving means should not be packaging film, which is used in conventional packaging units and can, for example, remain temporarily attached to the insert tool during unpacking of the packaging unit. The receiving means is intended to remain attached to the insert tool when the insert tool is operated with a power tool, in particular a handheld power tool, so that the receiving means leaves a characteristic impression on the operator of the drilling tool. The receiving means is, in particular, made of plastic material.

[0011] In this context, a “first means” is to be understood as meaning, in particular, a part of a packaging which is intended to present the insert tool, in that the part is designed, in particular, as a stand-up means, such as a stand-up base, for securely setting up the packaging unit, as an advertising means, such as an advertising carrier, for advertising the insert tool and / or as a fastening means, such as a hanger, for hanging the insert tool on a shelf.

[0012] In this context, a "holding state" is understood to mean a packaged or unopened state of a packaging unit in which the insert tool is held by the receiving means. A "separated state" is understood to mean an open state of a packaging unit in which an insert tool is, in particular, essentially separated from a packaging unit.

[0013] In this context, "positively locking" is understood to mean a connection of at least two parts that hinder or prevent relative movement to one another in at least one direction, such that such a connection of the two parts can only be separated from one another with the aid of separating tools, such as a saw, in particular a mechanical saw, etc., and / or chemical separating agents, such as solvents, etc. The at least two parts are to be connected to one another while avoiding further components or further means, such as adhesives. The at least two parts are designed, in particular, as mutually corresponding positively locking elements.In this case, a form-locking element, in particular a surface of a form-locking element, interacts with at least one corresponding form-locking element, in particular a contra-facing surface of the corresponding form-locking element. The two parts are to be understood as a connection of at least two components that can only be separated from one another with the aid of separating tools, such as a saw, in particular a mechanical saw, etc., and / or chemical separating agents, such as solvents, etc. One of these two parts can be designed, in particular, as a receiving means and the other part as an insert tool.

[0014] In this context, “directly connected” should be understood to mean at least form-fitting and / or connected without the need for additional components.

[0015] The term “one-piece” should be understood in particular as meaning at least materially connected, for example by a welding process, an adhesive process, an injection-molding process and / or another process that appears appropriate to the person skilled in the art, and / or advantageously formed in one piece, such as by production from a casting and / or by production in a single-component or multi-component injection-molding process and advantageously from a single blank.

[0016] In this context, "presentation device" is understood to mean a device intended to present an insert tool, in which the insert tool is stored, for example, in a lying, standing, or hanging position. The presentation device can be designed as a sales shelf with, for example, a support device for hanging packaging units.

[0017] The subclaims specify expedient developments of the packaging unit according to the invention.

[0018] It may be expedient for the packaging unit to have a holding means, particularly designed as a holding element, for holding the receiving means in a holding state, particularly in or on the packaging unit. Preferably, several holding means can be provided for holding the receiving means.

[0019] In this context, a "holding means" is understood to mean a means for holding a receiving means of the packaging unit and / or an insert tool. The holding means can be designed as a single piece with the receiving means.

[0020] In particular, the packaging unit can have a receiving area, in particular intended for receiving an insert tool, which contains the receiving means and / or the holding means of the packaging unit.

[0021] In this context, a "receiving area" is understood to mean an area of ​​a packaging unit intended to receive an insert tool and hold it in or on the packaging unit. In particular, the insert tool is held in or on the packaging unit by the holding means and / or the receiving means.

[0022] Preferably, the packaging unit can have a fastening area adjacent to or following the receiving area, preferably provided for fastening the packaging unit in or to a presentation device. The fastening area can have the first means, in particular the fastening means.

[0023] Furthermore, it may be expedient for a connecting means, particularly one having a weakened material, to be formed between the holding means, which is particularly designed as a holding element, and the receiving means. This advantageously allows the receiving means to be separated from the holding means, so that the receiving means remaining on the insert tool provides a high level of recognition for an operator and advantageously identifies the insert tool. Furthermore, the receiving means can be provided to dampen vibrations in the insert tool during operation of the insert tool.

[0024] A connecting element of the packaging unit, particularly designed as a weakened material, serves as a predetermined breaking point, which advantageously separates the receiving element from the holding element, in particular the receiving area. In particular, when separating the receiving element from the holding element, a user receives direct feedback, for example, through a click or crack, which clearly indicates to the user that the insert tool has now been released from the holding element of the packaging unit and that the insert tool can be used with the receiving element remaining on the insert tool.

[0025] In this context, a “connecting means” is to be understood as a structural element provided by design, mechanical or physical measures or designs that fails in a targeted or predictable manner, particularly when an intended load is exceeded. In particular, the connecting means can be designed as a weakened material. The weakened material can be designed as a perforation. The perforation can comprise a single material opening or a plurality of material openings. The weakened material can be designed as a predetermined breaking point. The weakened material can be a notch, a depression, a taper, such as a recess, or a weakening, in particular a targeted weakening, of the material or the material structure of the packaging unit.The connecting means can extend, in particular partially or completely, in the circumferential direction, preferably in a plane by 360°, around the insert tool in order to firmly and reliably hold or connect the holding means to the receiving means.

[0026] In particular, the connecting means is formed integrally with the holding means and the receiving means. This ensures that the holding means securely holds the receiving means in a held state and is reliably separated from the receiving means in a separated state, for example, by a tensile and / or torsional movement and / or an alternative relative movement.

[0027] It may also be expedient for the receiving means to be designed as a sheathing element and intended to positively engage the insert tool. The sheathing element can form a sheath around a portion of the insert tool. A "sheath" is understood, in particular, to mean a covering of the insert tool made of at least one additional material, which can, in particular, have a protective function.

[0028] It may also be expedient for the receiving means to be at least substantially hollow-cylindrical. In particular, the receiving means can enclose the insert tool in one plane by 360°. This allows the receiving means to form a firm and robust connection between the receiving means and the insert tool. In this context, "at least substantially hollow-cylindrical" is understood to mean a hollow-cylindrical basic shape, preferably with a deviation from this basic shape that is typical for a person skilled in the art.

[0029] It may be expedient for the receiving means to be provided to at least partially cover a recess in the insert tool, in particular a recess formed as a tapered portion. In particular, the tapered portion can enclose the insert tool in the circumferential direction in a plane by 360°. The tapered portion is preferably provided in or on an intermediate region of the insert tool.

[0030] In this context, an “intermediate region” is understood to mean a region of the insert tool arranged between the insertion region and the working region. The intermediate region can in particular be provided to bridge a desired distance between the insertion region and the working region, so that a desired tool length is achieved. The intermediate region can in particular have an outer contour that differs from the insertion region and / or working region. The intermediate region is preferably at least substantially rotationally symmetrical. In particular, the intermediate region can be provided to transmit forces and moments between the insertion region and the working region. In this context, “at least substantially rotationally symmetrical” is understood to mean a radius deviation around the tool axis of less than 10%, preferably less than 5%, particularly preferably less than 1%.Preferably, the intermediate region is formed integrally with the insertion region and / or at least parts of the working region.

[0031] In this context, a “taper” should be understood in particular to mean a partial area of ​​the intermediate area with a diameter that is reduced compared to a largest diameter of the intermediate area. In particular, the taper reduces a material cross-section of the intermediate area. In this context, a “material cross-section” should be understood in particular to mean a cross-section of the material of the intermediate area that is intended to transmit more than 50%, preferably more than 80%, particularly preferably more than 90% of the forces and moments between the insertion area and the working area. The material cross-section is preferably formed by a metallic material. In this context, a “diameter” of the intermediate area should be understood in particular to mean a diameter measured perpendicular to the longitudinal axis of the tool.In this context, a “partial area” is understood to mean a section of the intermediate area with a reduced diameter compared to the largest intermediate area diameter.

[0032] This allows the holding means to be reliably connected to the insert tool. Furthermore, increased stresses in the insert tool, which arise due to the recess and the associated reduced load-bearing cross-section of the insert tool, can be at least partially compensated for by the holding means. In particular, the holding means can serve as a damping element and be designed to dampen vibrations in the insert tool that occur during operation of the insert tool. In this context, "dampening" should be understood in particular as a reduction of extreme values ​​through a spring effect of the portion of the insert tool with the reduced diameter.

[0033] Furthermore, it may be advantageous for the holding device to be molded onto the insert tool. This ensures a firm and stable connection between the holding device and the insert tool.

[0034] In particular, the receiving means can limit the maximum extension of the packaging unit in a direction opposite to the first means. This allows the greatest possible force or moment to be applied to the connecting means in the event of exposure or separation of the receiving means from the at least one holding means, thus ensuring easy and safe release of the insert tool or the receiving means from the holding means.

[0035] Furthermore, it may be expedient for the receiving means to have a maximum outer diameter, and for an insertion region and / or a working region of the insert tool to have a maximum outer diameter, wherein the maximum outer diameter of the receiving means is less than or equal to the maximum outer diameter of the insertion region and / or the working region of the insert tool. As a result, the insert tool, in particular the insertion region of the insert tool, can be inserted particularly easily into, for example, a receiving device of a hand-held power tool, without reducing or preventing a clamping effect of the receiving device on the insertion region of the insert tool due to the receiving means being set back in the radial direction relative to the insertion region of the insert tool.

[0036] Furthermore, it may be expedient for the receiving means to have a maximum outer diameter, and for an insertion area and / or a working area of ​​the insert tool to have a maximum outer diameter, wherein the maximum outer diameter of the receiving means is larger than the maximum outer diameter of the insertion area and / or the working area of ​​the insert tool. As a result, when clamping an insert tool in a holding device of a machine tool, the receiving means can serve as a stop element that specifies or limits the clamping depth of the insert tool in the holding device.

[0037] Furthermore, it may be expedient for the packaging unit, in particular the receiving means of the packaging unit, to have at least one information element embodied as a number, a letter, a color, and / or a symbol. In particular, the information element can be designed as a raised portion and / or a recess. This allows a user to advantageously retrieve information from the receiving means, even after repeated use of the insert tool. This information is usually embossed, for example, on conventional insertion areas of drilling tools and becomes difficult to read with increasing wear or use of the drilling tool.

[0038] Furthermore, it may be expedient for the holding means to be designed as a holding arm or as a retaining ring. With a holding means designed as a holding arm, the insert tool and the receiving means can be separated from the holding means in a particularly simple manner by moving the insert tool and the receiving means relative to the holding means and / or the fastening area. The operator can freely choose between a rotational and / or a translational and / or another relative movement. With a holding means designed as a retaining ring, the retaining ring can be designed to be more stable than with a holding means designed as a holding arm, so that the retaining ring can proportionally absorb and reliably hold a greater weight of the insert tool. This can simplify packaging.

[0039] Furthermore, it may be expedient for at least the holding means to have a separating device for exposing or separating the insert tool and / or the receiving means from the holding means. In this case, particularly heavy insert tools or even popular insert tools, which are, for example, conspicuously often stolen without authorization, can be additionally secured against theft. As a result, a potential thief has to put in a relatively large amount of effort to separate the insert tool from the packaging unit or the first means and could thus refrain from stealing the insert tool. In particular, the separating device can be provided on the holding means and / or on the receiving means. The separating device can be designed as a connecting means, in particular as a weakened portion of the material and / or a material opening. The separating device can have a separating recess and / or a separating recess.The separating device is intended to weaken the packaging unit in a first step at a position provided for this purpose, in particular by means of an auxiliary tool, such as a clamping pliers or a screwdriver, and to at least partially expose the insert tool and to very easily separate the insert tool with the receiving means from the holding means of the receiving area in a subsequent step.

[0040] It may be expedient for the first means, in particular the fastening means, to have a material opening in the packaging unit and to be intended for suspending or fastening the packaging unit in or on a presentation device, in particular a display shelf or a sales shelf. In particular, the first means can be substantially triangular in shape, so that the packaging unit or the fastening area can be suspended on support rails comprising a single rail and / or a double rail or Euro-hole hooks. This allows the first means to be suspended securely and reliably in or on a sales device.

[0041] Preferably, the substantially triangular first means is oriented in the packaging unit such that a single suspension corner of the first means is aligned relative to the two further corners, starting from the receiving area in the direction of the fastening area. In particular, the suspension corner delimits the first means in a direction pointing from the receiving area to the fastening area. Preferably, the suspension corner of the first means is arranged at a distance from the two further corners of the first means in a direction pointing from the receiving area to the fastening area.

[0042] In this context, a “material breakthrough” is to be understood as meaning in particular a reduction in the material thickness, preferably of the first means, of the packaging unit by in particular 100% and / or a complete severing of the material thickness, preferably of the first means, of the packaging unit.

[0043] This has the particular advantage that the first means suspends the packaging unit more securely than, for example, a Euro hole, so that the support rails holding the packaging unit suspended can be changed from a double rail to a single rail without any problems, without the single rail becoming caught in an area of ​​the essentially triangular first means intended for the double rail if accidentally hung up, and thus resulting in the packaging unit being at an incorrect angle of alignment when hanging. The essentially triangular first means ensures that if the packaging unit is accidentally hung incorrectly on a support rail designed as a single rail, the weight acting on the packaging unit and the insert tool will align itself automatically, with the single rail sliding into the suspension corner or a central area of ​​the first means.

[0044] The invention further relates to a system comprising a packaging unit and an insert tool provided for receiving the packaging unit.

[0045] Brief Description of the Drawings Further advantages will become apparent from the following description of the drawings. The drawings illustrate exemplary embodiments of the invention. The drawings, the description, and the claims contain numerous features in combination. Those skilled in the art can also consider these features individually and combine them to form further meaningful combinations.

[0046] In the figures, identical components are provided with identical reference symbols.

[0047] The following figures each refer to a packaging unit in a substantially commercially available form with an insert tool, particularly designed as a drilling tool, a chisel, a bit, or a saw blade, with a rotary working movement and a translatory feed on a workpiece to be machined. The packaging unit is particularly intended to accommodate at least one insert tool designed as a rock drilling tool and to reliably hold it in or on the packaging unit.

[0048] Fig. 1 shows a perspective view of a handheld power tool 101 with an insert tool 1 received or clamped in a receiving device 105. The handheld power tool 101 has a handheld tool housing 103 with at least one gripping area 109 for gripping with at least one hand of a user. The receiving device 105 has a clamping device 107 with, for example, a plurality of clamping jaws. The clamping device 107 is intended to hold the insert tool 1, in particular to clamp or clamp it radially in the receiving device 105.

[0049] Fig. 2 shows a first embodiment of a packaging unit 3 according to the invention with a fastening area 5 and a receiving area 7 adjoining the fastening area 5 in the longitudinal direction L. The packaging unit 3 is designed for storing or receiving insert tools 1, such as drilling tools or bits or screwdriver bits. The packaging unit 3 is intended to accommodate precisely one insert tool 1. In an alternative embodiment, the packaging unit 3 can also be intended to accommodate multiple insert tools 1. The packaging unit 3 enables easy holding and storage of an insert tool 1 in the packaging unit 3, so that the largest possible area of ​​the insert tool 1 is displayed and accessible to a user or interested party.

[0050] The packaging unit 3 is at least substantially rectangular in shape with a main extension in the longitudinal direction L. In this exemplary embodiment, the packaging unit 3 is substantially flat, so that the packaging unit 3 is substantially flat and thin, with a main extension in the longitudinal direction L and a transverse extension spanning a plane orthogonal to the main extension in the transverse direction Q. The flat design of the packaging unit 3 has a front side V and a rear side R of the packaging unit 3 facing away from the front side V.

[0051] A “longitudinal direction” is to be understood as a direction along a main extension of the packaging unit 3 and / or in particular along a rotation axis a of an insert tool 1 held or received in the packaging unit 3.

[0052] In this context, a "transverse direction" is understood to mean a direction that is angled to the longitudinal direction, in particular at an angle in a range of approximately 85° to 95°, in particular in a range of 88° to 92°. In particular, the transverse direction can be understood to mean a direction that runs perpendicular or at a right angle to the longitudinal direction of the packaging unit 3.

[0053] The packaging unit 3 further has a longitudinal axis a, which is arranged parallel to the longitudinal direction L and in particular forms an axis of symmetry a, preferably of the receiving area 7, of the packaging unit 3, so that the axis of symmetry a divides the packaging unit 3 into two symmetrical packaging parts along the longitudinal axis L. This achieves a symmetrical alignment of the packaging unit 3 with an insert tool 1 received in or on the packaging unit 3, provided that the insert tool 1 is received coaxially to the longitudinal axis a in or on the packaging unit 1.

[0054] The fastening area 5 of the packaging unit 3 expediently has a first means 61 formed as a material opening 61a through the packaging unit 3, which serves to fasten the packaging unit 3 in or to a presentation device not shown in detail, in particular a presentation shelf or a sales shelf. The first means 61 is designed as a fastening means 61. The fastening means 61 is designed such that a support rail 121, for example of a presentation device, is guided through the fastening means 61 in order to suspend the packaging unit 3 or the fastening area 5 in a form-fitting and / or force-fitting manner on the support rail 121. The fastening means 61 can have an open shape, such as, for example, according to the hook-shaped fastening means 61 corresponding to Fig. 2, or a closed shape, such as according to the triangular fastening means 61 according to Fig. 4, have.

[0055] With the open form of the fastening means 61, it is not absolutely necessary to guide the support rail 121 through the fastening means 61, so that the support rail 121 can also be hooked laterally onto the fastening means 61. The open form of the fastening means 61 has a circular or elliptical material opening 61 which extends in the longitudinal direction L or along the longitudinal axis a and along the transverse direction Q of the packaging unit 3. The open form of the fastening means 61 additionally has a further material opening 61 which adjoins a lower part of the circular or elliptical material opening 61 and is arranged at a distance from the longitudinal axis a of the packaging unit 3. The further material opening 61 extends in the transverse direction Q to one side of the packaging unit 3 and makes it possible to provide an open or hook-shaped fastening means 61.As a result, the fastening area 5 is hook-shaped, so that the packaging unit 3 can also be guided transversely to the longitudinal direction L through the material opening 61 open to the side in order to hang the packaging unit 3.

[0056] The fastening area 5 further comprises a marking area 91 on the front side V of the packaging unit 3, which can be intended, for example, to be labeled or to be provided with labeling elements in the form of stickers or labels containing, for example, information and / or advertising material. The marking area 91 comprises a marking surface 93. The marking surface 93 is flat.

[0057] The receiving area 7 has two holding means 9 and a receiving means 11 designed as a sheathing element 11. The receiving area 7 is intended to receive an insert tool 1. The holding means 9 are elongated and extend essentially in the longitudinal direction L. The holding means 9 are designed as holding arms 9a and, in particular, connect the receiving means 11 to the fastening area 5 of the packaging unit 3.

[0058] The insert tool 1 in Fig. 2 to Fig. 5 is designed as a drilling tool. The drilling tool is a commercially available drilling tool with an insertion area 13 and a working area 15 adjoining the insertion area 13. The insert tool 1 has an insertion area 13 and a working area 15 with a diameter D4 and with a head (not shown in detail) with a cutting element 21. The working area 15 further has at least one groove 17 for removing accumulating drilling debris and two webs 19 delimiting the at least one groove 17. However, all possible embodiments of a working area 15 of the drilling tool 1 are conceivable here. The insertion area 13 and the working area 15 are connected by an intermediate area 14. The drilling tool 1 has an overall length which is divided into a working area length, a length of the intermediate area 14 and an insertion length. The drilling tool 1 is intended to produce rotationally symmetrical bores in a workpiece.The insertion area 13 serves to mount the drilling tool 1 in a tool holder of the handheld power tool and conforms to a suitable industry standard. The insertion area 13 can have at least one retaining recess 16 for the positive connection of the drilling tool to the holder device 105 of the handheld power tool or the handheld tool. In principle, further insertion areas 13 that appear appropriate to a person skilled in the art are also conceivable, such as insertion areas 13 comprising a plurality of retaining recesses 16 and / or grooves (not shown) that are at least partially analogous to, in particular similar to, and preferably identical to, an insertion area 13 corresponding to an SDS drilling tool.

[0059] The intermediate region 14 has a recess 23 in the form of a taper in a partial region 24. The length of the partial region 14a is greater than one-third of the insertion length and less than the sum of the insertion length and half the working region length. The partial region 14a is delimited by radii R. Starting from a largest diameter D2 of the intermediate region 14, the partial region 14a tapers in the region of the taper 23a with a diameter D3 down to a smallest diameter D4. Towards the working region 15, the diameter D3 of the intermediate region 14a increases again, starting from the smallest diameter 40a, until it has once again reached the largest diameter D2. The change in the diameter D3 occurs continuously in a shape approximating a parabola. The partial region 14a with the reduced diameter D3 extends over almost the entire length of the intermediate region 14.The smallest diameter D4 is reduced by 60% compared to the largest diameter D2 of the intermediate area 14.

[0060] The reduction of the diameter D3 of the taper 23a of the intermediate region 14 to the smallest diameter D4 dampens and limits torque peaks which can occur, among other things, during operation of the insert tool 1 when the cutting elements 21 of the insert tool 1 become caught in a workpiece to be machined.

[0061] Fig. 4 shows the insert tool of Fig. 3 shows a receiving means 11 designed as a casing element. The receiving means 11 forms a casing 11a that extends from an insertion region 13 to a working region 15 along an intermediate region 14. The receiving means 11 is made of a plastic material and is injection-molded onto the drilling tool 1. An outer diameter D1 of the receiving means 11 corresponds to a diameter D2 of the insertion region 13. The outer diameter D1 is advantageously 1-5% smaller than a diameter D5 of the working region 15, so that the receiving means 11 can be inserted into a borehole in a workpiece produced by the insert tool 1. The receiving means 11 covers a taper 23a of a partial region 14a of the intermediate region 14.

[0062] The recess 23 is designed as a taper 23a in diameter, such as in accordance with patent application DE 10 2012 224 437 A1 or DE 10 2012 224 434 A1 of the insert tool.

[0063] The receiving means 11 is arranged along the longitudinal direction L in a direction of the receiving area 7 of the packaging unit 3 facing away from the fastening area 5 of the packaging unit 3 and limits a maximum extension of the packaging unit 3 in the longitudinal direction L. The receiving means 11 is circular and completely encloses the recess 23 of the insert tool 1 on one plane by 360°. The receiving means 11 is integrally connected to the holding means 9. The two holding means 9 limit the receiving means 11 in the transverse direction Q. The receiving means 11 limits a maximum extension of the packaging unit 3 in the longitudinal direction L in order to be able to detach the receiving means 11 from the holding means 9 as easily as possible. The receiving means 11 is provided to hold the insert tool 1 on the packaging unit 3.

[0064] The receiving area 7 has a connecting means 27 between the receiving means 11 and the two holding means 9, which connecting means 27 connects the receiving means 11 to the holding means 9 in a materially bonded manner. Alternatively, the connecting means 27 can be provided between the receiving means 11 and a single one of the two holding means 9. The connecting means 27 has a material weakening 27. The connecting means 27 is designed as a predetermined breaking point and is intended to fail specifically at this predetermined breaking point when an inadmissibly high tension is reached. The connecting means 27 can be designed as a notch or a depression or as a perforation. The user of the packaging unit 3 can, for example, grip the fastening area 5 of the packaging unit 3 with one hand and, with the other hand, the working area 15 of the insert tool 1 in order to load the fastening area 5 relative to the working area 15.to twist and thus generate a maximum force on the connecting means 27. As a result, the insert tool 1 with the receiving means 11 can be separated from the holding means 9 particularly easily, as shown, for example, in . Fig. 5. The receiving means 11 remains on the insert tool 1 after successful separation or exposure from the holding means 9.

[0065] The receiving area 7 further has a viewing area 41. The viewing area 41 is delimited by the holding means 9 and the receiving means 11. The viewing area 41 allows both visual and tactile access to the insertion area 13 of the drilling tool, allowing the user to inspect and preselect, for example, the insertion area 13 of the drilling tool.

[0066] The receiving means 11 further comprises an information element 47 that can provide a user with information, such as a company name, a purpose, or other information useful to an operator. For example, the information element 47 can be configured as a color that is assigned to a color table, for example, information that can be retrieved from the marking area 91, in order to facilitate a suitable selection of the insert tool 1 for the operator. Furthermore, the information element 47 can enable advantageous recognition of the insert tool 1 for the operator.

[0067] The Fig. 6 shows a second embodiment of the packaging unit 3 according to Fig. 2. The packaging unit 3 also has a viewing area 41, which in this embodiment, however, is essentially circular. The viewing area 41 is delimited by a substantially hollow-cylindrical wall 43.

[0068] The wall 43 has an inner region 45a and an outer region 45b surrounding the inner region 45a. The inner region 45a has an inner surface 43a. The outer region 45b has an outer surface 43b facing away from the inner surface 43a. The inner region 45a delimits the viewing area 41 of the packaging unit 3.

[0069] The wall 43 further has a first recess 49a and a second recess 49b opposite the first recess 49a, which are provided for passing the insert tool 1 through and receiving or holding it in the packaging unit 3. The first recess 49a and the second recess 49b are arranged concentrically to one another, whereby the insert tool 1 can be securely and reliably fixed in the packaging unit 3. The two recesses 49a, 49b are arranged along the longitudinal axis a of the packaging unit 3 extending in the longitudinal direction L of the packaging unit 3. The first recess 49a is provided in an area adjacent to the fastening area 5. The second recess 49b is provided in a freely projecting area of ​​the receiving area 7 of the packaging unit 3 facing away from the fastening area 5.

[0070] Adjacent to the first recess 49a, the inner surface 43a of the inner region 45a has a fixing means 51 for fixing the insert tool 1 in or on the packaging unit 3. The fixing means 51 is hook-shaped. The fixing means 51 extends in the longitudinal direction L, projecting from the inner surface 43a of the inner region 45a. The fixing means 51 protrudes into the viewing area 41. The fixing means 51 additionally extends orthogonally to the longitudinal direction L and the transverse direction Q, so that the fixing means 51 protrudes, for example, into a holding recess 16 of the insert tool 1 accommodated in the packaging unit 3 and thus positively protects the insert tool 1 from falling or slipping out.The fixing means 51 can further be provided to hold the insert tool 1 in the packaging unit 3, so that the connecting means 27 is relieved and thus the connecting means 27 can be designed to be less robust than a connecting means 27 of a packaging unit 3 which does not have a fixing means 51.

[0071] The closed fastener 61 in Fig. 6 is essentially triangular in shape. The fastening means 61 has three rounded corners and three straight edges connecting the rounded corners. Alternatively or additionally, the fastening means 61 can have at least partially rounded or even pointed corners. Alternatively or additionally, the corners can be polygonal. Alternatively, at least one of the edges can be at least partially curved. The fastening means 61 is aligned in the packaging unit 3 such that a corner designed as a suspension corner 97 is spaced apart from the two other corners of the fastening means 61 in the longitudinal direction L and delimits the fastening means 61 in a direction pointing from the receiving area 7 to the fastening area 5.

[0072] The marking area 91 has a first marking surface 93a and a second marking surface 93b. The two marking surfaces 93a, 93b are flat. In an alternative embodiment, the marking surfaces 93a, 93b can be curved. The marking surfaces 93a, 93b are angled relative to one another and adjoin one another along the longitudinal direction L of the packaging unit 3.

[0073] In Fig. 7 and Fig. Figure 8 shows the holding means 9 of the second embodiment of the packaging unit 3. The holding means 9 is designed as a holding arm 9b. The holding arm 9b is flat and extends in the longitudinal direction L and in the transverse direction Q. An extension orthogonal to the longitudinal direction L and the transverse direction Q is substantially smaller than an extension in the longitudinal direction L or in the transverse direction Q.

[0074] The retaining means 9 has a taper in the transverse direction Q, which adjoins the connecting means 27 in the longitudinal direction L and forms a minimal extension of the retaining means 9 in the transverse direction Q. The taper adjoins the connecting means 27 and redirects forces and stresses acting upon loading of the retaining means 9 to the connecting means 27. The connecting means 27 is designed as a material weakening. The connecting means 27 is designed as a notch.

[0075] Furthermore, the viewing area 41 has two stabilizing elements 53, which are located opposite one another and protrude into the viewing area 41. The stabilizing elements 53 are intended to compensate for a weakening of the wall 43 due to the recesses 49a, 49b provided in the wall. The two stabilizing elements 53 are designed as stabilizing tongues. The two stabilizing elements 53 are arranged on the rear side R of the packaging unit 3 and delimit the viewing area 41 in the longitudinal direction L and in the transverse direction Q. The two stabilizing tongues are each arranged adjacent to the recesses 49a, 49b of the wall 43.

[0076] Fig. 9 and Fig. 10 show a third embodiment of the packaging unit 3 according to the invention according to Fig. 2. The holding means 9 is designed as a retaining ring 9c and adjoins an outer surface 43b of the wall 43. The holding means 9 is at least substantially hollow-cylindrical. The holding means 9 encloses the insert tool 1 in a plane by 360°. The holding means 9 is arranged concentrically to the receiving means 11. The holding means 9 is connected to the receiving means 11 via the connecting means 27. The connecting means 27 has a perforation such that the connecting means 27 has a plurality of material openings 85 in the circumferential direction around the longitudinal axis a, which are separated from the material webs 87 connecting the holding means 9 and the receiving means 11. The material openings 85 have a maximum extension along the circumferential direction around the longitudinal axis a that is greater than a maximum extension of the material webs 87 along the circumferential direction.

[0077] The wall 43 of the receiving area 7 has a separating device 71 for exposing the receiving area 7 of the packaging unit 3 from the insert tool 1 and / or the receiving means 11. The separating device 71 comprises a material weakening 73 extending substantially orthogonally to the longitudinal direction L and the transverse direction Q. The material weakening 73 can be designed as a separating notch and / or as a separating recess. The separating notch 73 is provided to enable easy separation of the wall 43 of the receiving area 7 by the user separating the wall 43 at the separating notch 73 using an auxiliary tool, such as, for example, gripping pliers or scissors. As a result, the load-bearing effect of the wall 43 of the receiving area 7 and / or of the stabilizing element 53 on the insert tool 1 is reduced orminimized, so that, for example, a tensile and / or bending load on the fastening area 5 essentially affects the connecting means 27 between the holding means 9 and the receiving means 11. This also achieves particularly reliable protection against theft of the insert tool 1 located in the packaging unit 3, in that the separating device 71 of the receiving area 7 prevents a tensile and / or bending load from essentially affecting the connecting means 27 or the material weakening 27, and thus an overly rapid removal of the insert tool 1 from the packaging unit 3 is reliably prevented.

[0078] The separating device 71 further comprises, for example, Fig. 9, a separating recess 75 extending in the longitudinal direction L of the holding means 9. The separating recess 75 is delimited in the longitudinal direction L by the separating notch 73 and a separating web 77 opposite the separating notch 73. The separating recess 75 is provided to generate a rotary movement separating the separating web 77 by means of an auxiliary tool engaging in the separating notch 73, such as a screwdriver or scissors.

[0079] In contrast to the second embodiment, the second marking surface 91b of the third embodiment has a security recess 81. However, the security recess 81 is not limited to the third embodiment, but can also be provided in the first or second embodiment of the packaging unit 3. The security recess 81 is intended to accommodate a security element (not shown in detail), such as an RFID transponder, for protection against theft. The security recess 81 extends along the longitudinal direction L of the packaging unit 3.

[0080] Fig. 11 shows various embodiments of the first means 61 designed as a fastening means 61, wherein Fig. 11a and Fig. 11b the preferred fastening means 61 compared to the Euro hole fastening means 62 already known from the prior art according to Fig. 11c and Fig. 11d shows examples of Fig. 11a and Fig. 11c shows how the fastening means 61 is suspended from a support rail 121 designed as a double rail. The support rail 121 designed as a double rail defines two support areas that securely fix the packaging unit 3 and align the longitudinal axis a of the packaging unit 3 substantially parallel to a center of gravity of the packaging unit 3, so that the packaging unit 3 and the insert tool 1 are vertically aligned in or on a presentation device, such as a sales shelf. Fig. 11b and Fig. 11d, the fastening means 61 is suspended from a support rail 121 designed as a single rail. The support rail 121 designed as a single rail merely defines a support area that fixes the packaging unit 3. In this case, a Euro-hole fastening means such as in Fig.11d, an unfavorable alignment of the packaging unit 3 in or on a presentation device can occur if the longitudinal axis a of the packaging unit 3 is angled to a center of gravity of the packaging unit 3. This occurs, for example, when the single rail rests on a support area provided for the double rail. As a result, the packaging unit 3 is aligned laterally so that it is no longer aligned vertically along the longitudinal direction L of the packaging unit 3, but rather angled to the longitudinal direction L of the packaging unit 3. This is an undesirable effect that can arise if a packaging unit 3 is inadvertently hung up in an unfavorable manner using a Euro hole fastener.This is prevented with the preferred, substantially triangular-shaped fastening means 61, since even if the individual rail is inadvertently positioned unfavorably on the fastening means 61, the fastening means 61 aligns itself due to the force of gravity acting on the packaging unit 3, so that the individual rail moves or slides into the position of the fastening means 61 predetermined for the individual rail.
