according to Austrian patent application: A 1340 / 67-3Ob from 13 _O 2.1967, "elastic toothpick"

The invention relates to a plastic toothpick. Compared to wooden toothpicks, plastic toothpicks have a number of advantages, they are cheaper to manufacture, do not break like that " easily and can be sterilized more easily.

The known toothpicks, plastic can not · ■ fully satisfactory, especially as regards their elasticity. Either due to their shape, especially due to sharp bends, they are as stiff as a toothpick made of wood) they then only penetrate the spaces between the teeth to a certain depth, whereby the point between the teeth can only exert an insufficient cleaning effect deeper.

Other versions are completely or almost flat. This toothpick penetrate though well into the interdental spaces, but there are $ The total ä

Arched tooth surfaces are only inadequately cleaned, as the edges of the toothpicks only inadequately anoint the curved ones when the handle is turned To the tooth surfaces. It is still a disadvantage that the handle is a has low rigidity against torsion.

The toothpick according to the invention differs from these known designs in that the Bkolett surface of the toothpick material is a spatial surface that can be developed on a plane, and that cuts through this skeletal surface are perpendicular to the IjKngsachee des

Toothpick curves without significantly reducing the elasticity of the toothpick diminishing kinks are. The one under the skeleton area should be Area to be understood to be anywhere from the two opposite Surfaces of the material have the same distance.

In this embodiment of the toothpick according to the invention, even if a relatively stiff plastic is used, a threefold elasticity achieved: the toothpick can be bent twist, and it adapts itself in its strength to the tooth gap.

The handle part is advantageously made much stronger than the active part, which is achieved, for example, by means of a circular cross-section can be*

Further advantages of the toothpick according to the invention go atis the following description of an exemplary embodiment. The invention however, should not be limited to this, in particular the Reference numbers for explanation only.

Figures 1 to k represent different views of the toothpick. Figure 5 shows the punched plastic tape before deforming. Figure 6 illustrates the effect of the toothpick in use.

As FIG. 5 shows, a strip of plastic is made into a strip punched out on both sides of a central part 1 at one end a Point 2 and at the other end two points 3 in the shape of a dovetail has · It is advantageous that the punching takes place in the subsequent cut. Any advertising imprint (see Fig. 4) is expedient already applied to the middle part t beforehand.

Then, advantageously on the same machine, the tape is rolled in its central part on a cylindrical handle part, the pointed ends a correspondingly curved. Take shape. How nua the

Representation of the finished toothpick can be seen in FIGS. 1 to k , the cuts XX at the active ends are then arcs perpendicular to the longitudinal axis AA of the toothpick, i.e. they have no clicks (see also

This results in a threefold elasticity! Once it fits Strength "s" (Fig. 3 and 6) by feathers on the circular arc of the tooth gap, The edges of the toothpick slide along the surface of the teeth in a scraping process. Second, a bend in the direction of arrow "B" is possible, which also cleans badly accessible tooth gaps easily and effectively «Finally, the toothpick can also be turned around the axis A-A turn, which further increases its adaptability «

, The tips 3 of the toothpick form an active part with raised Elasticity, which can also act in the manner of a pair of pliers "

The handle part is in contrast to this by its cylindrical shape stiff enough to withstand strong finger pressure.
