Description

FIELD OF THE INVENTION

The present invention relates to a package for receiving an accessory of a tool.

BACKGROUND OF THE INVENTION

In the prior art blister packs for packaging accessories are known. In a blister pack several accessories can be arranged. As a result, packaging of each accessory can be avoided. Power tools may in particular be hand-held tools having a support means, such as a handle, with which the power tool can be held by a user, carried and guided in the machining of a workpiece. The power tool has a drive motor that drives a drill, grinding or cutting disc, circular saw, etc., and can bring about rotation or oscillation, for example. The oscillation may in particular be a rotational oscillation. To connect the drill, the grinding or cutting disc or circular saw with the power tool a tool interface is provided.

SUMMARY OF THE INVENTION

Blister packs largely replicate the outer contours of an accessory to be packaged. This makes blister packaging a very compact package to protect against damage to the accessories. It is advantageous to provide only one type of blister packaging for several similar accessories of a power tool, such as saw blades, sanding plates, etc. As a result, the production and stockpiling of different blister packs can be avoided. The disadvantage here can be the lack of adaptation of the blister pack to the corresponding accessory to be packaged, whereby the accessory can slip, twist and damage within the blister pack. A risk of damage exists in particular if several accessories are arranged within a blister pack. In particular, a plurality of accessories may be stacked within a blister pack.

It is therefore an object to provide a blister pack which is suitable for several different accessories of power tools and which reliably prevents slippage of the accessories within the blister pack.

As a first embodiment of the invention there is provided a package for receiving an accessory of a tool, the tool having a tool interface for transmitting torque to the accessory, comprising: a first protrusion for engaging the accessory and a second protrusion for receiving an area the accessory, wherein the first survey in one or more sections or along a complete circumference of the survey has a replica of the tool interface as an outer structure and / or wherein the second survey in one or more sections or along a complete circumference of the survey a replica of the tool interface as Has inner structure.

By forming a replica of the tool interface of the power tool as a contour of the blister packaging secure recording of an accessory to be packaged can be guaranteed. As a result, a translational displacement of the accessory is prevented within the blister pack. In addition, a rotational movement of the accessory is avoided because the accessory is stored in the replica of the tool interface, which prevents rotation.

Advantageously, in the embodiment according to the invention, only a small number of cardboard inserts are required in order to prevent a displacement of the accessories to be packaged, since rotation, slipping, twisting or shifting of the accessories can be precluded by simulating the tool interface.

Exemplary embodiments are described in the dependent claims.

According to an exemplary embodiment of the invention, a package is provided, the replica being a circular or cup-shaped structure with a wave pattern or a star-like polygon.

By a corresponding design of the survey, a slipping or rotating the packaged accessory to the survey, which is a replica of the tool interface can be avoided.

In a further embodiment of the invention, a package is provided, the package having a top and a bottom, wherein the first bump is located on the bottom and the second bump is on the top.

According to an exemplary embodiment of the invention, a packaging is provided, wherein the upper side is pivotable towards the lower side in order to a pivoted state to achieve encapsulation of the accessory and / or wherein the top and bottom are connected to each other.

A pivoting of two corresponding parts allows easy to achieve encapsulation, whereby the relevant accessories are fully protected against environmental influences.

In accordance with another embodiment of the present invention, a package is provided wherein the package is adapted to receive stacked 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, or any number of accessories, with one twist is prevented by the first and / or second survey and / or the replica.

Packaging multiple accessories with a single blister pack allows for economical packaging.

Proper packaging of the accessories prevents slippage or twisting of the packaged accessories. As a result, a risk of damage can be excluded.

In a further embodiment of the invention, a packaging is provided, wherein the first elevation in conjunction with the second elevation leads to a clamping of the accessory.

By clamping by means of two corresponding elevations a "rattling" of the accessories can be prevented within the package.

According to an exemplary embodiment of the invention, a packaging is provided, wherein the tool is a power tool or a pneumatically driven tool and / or wherein the tool is a hand-held tool.

In a further embodiment of the invention, a packaging is provided, wherein in the packaging optionally a first or a second accessory can be arranged and / or wherein several accessories can be arranged simultaneously in the packaging, wherein the accessories may be the same or different and / or or optionally wherein a first or a second number of accessories may be arranged in the package.

By arranging an "anti-twist device" by means of replicating the tool interface, different and / or different quantities of accessories can be arranged in a package without the risk of slippage or twisting and damage to the accessories.

According to an exemplary embodiment of the invention, a package is provided, the package being made of plastic, in particular polyvinyl chloride (PVC), polypropylene (PP), acryl-butadiene-styrene (ABS), polymethyl methacrylate (PMMA), polyurethane, polyvinyl alcohol or polycarbonate (PC).

In a further embodiment of the invention, a package is provided, the package being a blister package.

According to an exemplary embodiment of the invention, a package is provided, wherein the replica deviates in one or more dimensions by + - 3/10 mm, preferably by + - 5/10 mm, particularly preferably by + - 1 mm from the tool interface ,

As an idea of the invention can be considered to form a blister pack in such a way that the blister pack is adapted to the tool interface of a power tool and otherwise provides clearance for the formations of different accessories to be packaged. The accessories for a particular power tool may be appropriate for the tool to be machined or be formed differently for the activity to be performed. However, all accessories for a particular power tool have the same shape for the tool interface of the power tool. Because of this, this tool interface can be completely formed by the blister package. Furthermore, by means of this tool interface, the accessories can be stacked within the blister pack, whereby slipping is prevented by the shape of the tool interface. Overall, results in a blister packaging, the slipping of accessories, even if different accessories are to be packed, safely avoids.

Of course, the individual features can also be combined with each other, which can also be partially beneficial effects that go beyond the sum of the individual effects.
