Abstract

Provided is a interdental cleaning agent comprising at least one blade for insertion into a tooth space, wherein at least one blade edge in the region of the blade, which is introduced for cleaning in the interdental space, is truncated in order to avoid gum injuries.

Description

Provided is a means for cleaning a interdental space of contaminants, such as food scraps.

To clean the interdental space toothpicks or dental floss are known from the prior art.

Furthermore, the document describes DE 602 17 543 T2 a tooth cleaning paper in conjunction with dental floss. It is a square sheet of paper whose side edges have concave sections. These inwardly curved edge sections are bridged in a straight line by sewn-in dental floss. The tooth cleaning paper is used to remove food residue left on or between the teeth. To remove food scraps from the interdental spaces, the floss is used in a known manner. Remains of food adhering to the tooth surfaces are removed by rubbing the tooth surfaces with the tooth cleaning paper.

It is the object of the present application to provide an alternative means of removing food residues from interdental spaces that is easy to carry in everyday life.

This object is achieved by the interdental cleaning agent having the features of claim 1.

The interdental cleaning agent in the sense of the present application comprises at least one sheet for insertion into a tooth space. At least one blade edge in the region of the blade, which is introduced into the interdental space for cleaning, is blunted in order to avoid gum injuries.

In order to meet different interdental spaces, that is to say different distances between adjacent teeth, the at least one leaf can have a corresponding layer thickness. In other words, a sheet may be provided and purchased in different layer thicknesses depending on the individual tooth pitches.

It is also conceivable that the at least one sheet has different layer thicknesses in sections. These sections, different layer thicknesses can be provided according to individual tooth spaces. For example, the incisor spacing may be greater than the molar spacing. If the sheet now has a first section with a first layer thickness and a second section with a second layer thickness, then z. B. the first layer thickness be selected according to the incisive tooth spacing and the second layer thickness according to the molar distance.

Alternatively or additionally, the at least one sheet may be foldable. By folding the sheet, the layer thickness can (again) be varied. With a uniform layer thickness of the sheet, the layer thickness can be multiplied by folding. Depending on the direction of the fold and the number of folds, a multiple of the section thickness, a thickness corresponding to the sum of the individual layer thicknesses, or even a thickness corresponding to the sum of multiples (Σn × layer thickness per section, n = 1, 2, 3 , ...) of the individual layer thicknesses are achieved.

The at least one sheet may have a coating. For example, the coating can help lubricate the blade between the teeth during the cleaning process. For this purpose, for example, a wax coating would be conceivable. The coating may also be antibacterial to contribute to oral hygiene. To provide a fresh breath, a fragrance-containing coating is used. The aforementioned coating types can also be combined as desired.

For the sheet different materials are conceivable. For example, paper or plastic can be used. However, other materials which can be provided in sheet form are also conceivable.

If the sheet of paper so truncated sheet edges can be realized for example by a "fraying" of the paper. Frayed leaf edges, for example, are the result of ragged edges. On the other hand, sharp edges are known to occur when cutting paper sheets.

If the sheet is made of plastic, truncated sheet edges can be realized, for example, by deburring. When deburring the sheet edges can be rounded in an advantageous manner.

Preferably, the at least one sheet has four leaf edges in the form of two pairs of opposing leaf edges. Leaf edges of a pair do not necessarily have the same shape or the same edge course. You can z. B. have along a central axis of the blade axis mirrored course.

At least one sheet edge may be rectilinear or have a concave or convex curvature. It is also conceivable that a sheet edge has different shapes in sections. Any combination of rectilinear and concave or convex curved is possible. For example, a blade edge may be rectilinear in its end portions and have a concave or convex curvature in a central portion. Alternatively, the blade edge can also be arched in the end sections and be rectilinear in the central section. An at least central convex curvature, for example, is particularly well suited to clean molar spaces due to their limited accessibility. For the cleaning of incisors, however, an at least partially concave curvature is well suited. The incisors are more accessible and the inwardly curved edge shape counteracts a cutting into the gums. A sheet therefore particularly advantageously has an opposite edge pair with a concave and a convexly curved edge or an edge with at least a central concave curvature and an edge with at least a central convex curvature.

Preferably, the interdental cleaning agent comprises a plurality of sheets provided in a releasable composite. From this composite, the leaves are individually herauslösbar.

Such a composite can be realized in various ways, for example by stitching or by spiral binding of the individual sheets. Particularly in the case of stapled but also spiral-bonded sheets, it is advantageous to provide these with perforated tear-off lines in order to facilitate controlled detachment of the individual sheets from the composite.

Alternatively, the sheets may also have a pressure-sensitive adhesive-coated strip on their rear side, by means of which they can be fastened to the front side of another sheet opposite the back side. Such a composite form is known from Post- ^it® blocks. In the composite adhesive bonding of the sheets can always be done on the same edge side or alternately on opposite edge sides. In the latter variant, the sheets adhesively bonded in the composite can be pulled apart in concertina form.

As a further alternative composite form, the block bond can be selected.

Each or at least one sheet of the plurality of sheets may differ in layer thickness from the composite preceding and / or following sheet. For the layer thicknesses of the sheets, reference is made to the above.

The plurality of leaves may have leaves with different leaf edge profile. In other words, each or at least one sheet of the plurality of sheets in the sheet edge course may differ from the composite preceding and / or following sheet.

In the 1 to 3 exemplified three different sheet designs are shown, which are not construed limiting the present application.

1 shows a square leaf 10 a toothpaste cleaning agent according to the application. Two opposite leaf edges 12 . 14 are straightforward. The two other leaf edges 16 . 18 are each concave, in other words curved inwards.

The leaf 10 ' out 2 is different from the sheet 1 only by the fact that the two the opposite, straight leaf edges 12 . 14 connecting leaf edges 16 ' . 18 ' each convex, that is arched outward.

Close light shows 3 a leaf 10 '' extending from the leaves according to the 1 and 2 it differs in that the two the opposite, straight leaf edges 12 . 14 connecting leaf edges 16 '' . 18 '' each are also rectilinear.

Generally, a quadrangular and in particular rectangular configuration of the leaves 10 . 10 ' . 10 '' prefers. Two opposite edges 12 . 14 and at least a portion of the subsequent sheet area then serve to be held by a user, e.g. B. by this attacks with his thumb and forefinger on corresponding areas of opposite leaf sides. The leaf edges joining these attack area leaf edges 16 . 18 . 16 ' . 18 ' . 16 '' . 18 '' These are the leaf edges that can be inserted into the interdental space to clean the interdental spaces and that are blunted to prevent gum injuries. The leaf edges associated with the attack areas 12 . 14 In particular, they may be shorter than the leaf edges connecting the engagement region blade edges and usable for cleaning the interdental space 16 . 18 . 16 ' . 18 ' . 16 '' . 18 '' ,
