Description:
REFILL STAPLES HAVING END MARK

FIELD OF THE INVENTION

[0001] The present invention relates to refill staples and especially to refill staples in stick form.

BACKGROUND OF THE INVENTION

[0002] Staplers for applying staples are often designed for receiving refill staples in stick form. The staplers are often made of opaque material and a user of the staplers may inconveniently run out of staples without warning.

SUMMARY OF THE INVENTION

[0003] The present invention avoids the inconvenience of the prior art.

[0004] According to the invention, there is provided refill staples in stick form. The stick of the refill staples has substantially a first color. The stick of the refill staples has at one end an end mark having a second color. The second color contrasts with the first color. The end mark having the second contrasting color extends over a plurality of staples.

[0005] Advantageously, the second contrasting color as it starts appearing on stapled staples provides a user with an early warning that the stick of the refill staples is about to run out of staples. The early warning allows for the plurality of staples to be still available for use.

BRIEF DESCRIPTION OF THE DRAWINGS

[0006] The drawings illustrate the preferred embodiments of the invention by way of example only.

Figure 1 shows a perspective view of a preferred embodiment of the invention;

Figure 2 shows a top view of a variant of the preferred embodiment of the invention; and Figure 3 shows a top view of another variant of the preferred embodiment of the invention.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0007] The following descriptions describe the preferred embodiments of the invention by way of example only. [0008] Figure 1 shows a perspective view of refill staples in stick form 100 as a preferred embodiment of the invention. The refill staples stick 100 has substantially a silver metallic color. The refill staples stick 100 has on one end a rectangular mark 102 having a black color. The black color contrasts with the silver metallic color. The end mark 102 extends over a plurality of staples, for example 12 staples, thus providing a user with an early warning that the refill staples stick 100 is about to run out of staples. In this numerical example, the early warning allows for the final 12 staples to be still available for use.

[0009] Figure 2 shows a top view of a variant of the preferred embodiment shown in Figure 1 . A black end mark 104 has a triangular shape, thus providing the user with an early and gradual warning on how few staples are left in the refill staples stick 100, the less silver metallic color the staples have, the less staples are left in the refill staples stick 100.

[0010] Figure 3 shows a top view of another variant of the preferred embodiment shown in Figure 1 . An end mark 106 has a black triangular shaped part 108 and a red rectangular shaped part 110. The red color of the rectangular shaped part 110 contrasts with the black color of the triangular shaped part 108. The black triangular shaped part 108 of the end mark 106 provides an early and gradual warning that the refill staples stick 100 is about to run out of staples. The red rectangular shaped part 110 of the end mark 106 at the very end of the refill staples stick 100 provides a final warning to the user that only a few final staples are left in the refill staples stick 100. As a second numerical example, the red rectangular shaped part 110 extends over the final 3 staples of the refill staples stick 100, thus providing the user with the final warning for the final 3 staples of the refill staples stick 100.

[0011] Silver metallic, black, and red have been used in the hereinbefore as an example of contrasting first, second, and third colors, but any set of contrasting colors may be used for marking the one end of the refill staples stick 100. The contrasting colors may be applied using a coloring agent such as ink.

[0012] A person skilled in the art will have by now appreciated the full scope of the invention. In particular, the scope of the invention is not limited to the preferred

embodiments described by way of example in the above.
