DESCRIPTION:
BRIEF SUMMARY
BACKGROUND OF THE INVENTION
It is previously known to make packages for tools in the shape of more or less open frames protecting sharp cutting edges from damaging or being damaged by other objects, as described in patents U.S. Pat. No. 5,044,591 and GR 1 553 549. The package can also be made with a tamper-proof seal when they are first applied around the tool, requiring some clearly visible alteration to the package to remove it from the tool, possibly requiring the use some other tool, such as described in patents U.S. Pat. No. 5,148,914 and GB 2 112 731. This shows the buyer that the tool is unused and will also discourage pilfering at self-service stores.
The patent SE 8700631-8 shows a package where an indicating seal must be torn away the first time the package is opened. This package has the disadvantage of not being adaptable to tool with different lengths, and tearing of the seal may damage other part of the package, making it unsuitable for further use.
OBJECTS OF THE INVENTION
The present invention is a package which is easily adaptable to tools of different length, and which requires some tool for tearing of the seal, and where tearing of the seal will not reduce the possibility of further use.
DESCRIPTION OF THE DRAWINGS
FIG. 1 is a perspective view of a tool package according to the present invention.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
A tool package according to the invention comprises an elongated frame-type part, an upper cross-bar of which has a centering support and a lower cross-bar of which, has an hole and outside of that hole a slideable retailer. As long as a seal on the retainer is intact, the retainer can only be moved towards the hole, locking the elongated tool between the retainer and the centering support. When the seal has been torn or removed, the retainer can be moved in both directions, to allow the tool to be freed or replaced.
One embodiment of the invention is shown in FIG. 1, showing a package for an elongated tool such as a drill or drill extension shaft. The package comprises a frame with two longitudinal sides (12), one upper cross-bar (13) and one lower cross-bar (14). The frame may have a flat bottom (11) which may have one or more cutouts to make the tool visible from more directions or to simplify mounting or removal. The upper cross-bar is made with a centering support (15) which will support the tool not allowing it to be lifted out of the frame or moved to one side. For drills and similar rotatable tools this means that the support (15) at the upper cross-bar (13) can be made with a projecting collar encircling the end of the tool, or a projecting point which can enter a recess in the tool, or a narrow hole where part of the tool point but not the whole tool can penetrate, or a combination of those. The upper cross-bar (13) or the support (15) can be made with a limited resilience to hold the tool more safely.
The bottom (11) of the frame can be plain or provided with holders (16) for accessories such as hexagon kelps for setting of adjustable drills. The holder can be resilient or located where the tool will keep the accessory from falling out.
The lower cross-bar (14) of the frame is made with a hole (17) large enough that the tool end can easily be pushed through. Below the lower cross-bar the package comprises extensions (18) of the longitudinal sides (12), at least partly made as toothed racks, and a retainer (19) with hooks (20) which can engage the racks. The extensions (18) have longitudinal slots (21) adjacent the racks.
The retainer (19) is separate from the frame and the extensions (18). It has two parallel legs (22) with hooks (20) which can engage the teeth of the racks. Hooks and teeth are unsymmetrical to allow sliding the retainer upwards only, but not downwards, when they are engaged. The upper parts of the legs (22) are connected by a retaining cross-piece (23) shaped as a support for the lower end of the tool. The lower parts of the legs (22) are connected by a seal cross-piece (24) shaped to be easily broken or rem
