DETAILED DESCRIPTION OF EMBODIMENTS OF THE INVENTION

[0032] A first embodiment of a dental floss holder according to the invention is disclosed in FIG. 1. This specific embodiment has four floss supporting arms 1, wherein each arm has a first end 2 and a second end 3. The first end 2 of each supporting arm 1 is joined to the connecting section 4 (or hub). In this embodiment, the connecting section is formed by the four first ends 2 joined, or connected together. At the second end 3, the supporting arms 1 feature a rounded surface 5 in the form of a knob 5 or ball. The rounded surface ensures that the dental floss holder is comfortable to have in the mouth by avoiding any sharp edges which may hurt or scratch the gums or palate. Each of the supporting arms 1 is connected to a neighboring supporting arm by a string of dental floss 6. In this particular embodiment, each of the supporting arms 1 is connected to three neighboring supporting arms, each connection by a string of dental floss 6. Each string of dental floss is connected to a floss fastening portion 7 at the second end of a supporting arm. The fastening portion 7 is preferably arranged between the rounded surface 5 and the connecting section 4. As can be seen, the multiple strings of dental floss are arranged to constitute the edges of a polyhedron, or more specific in this case, a tetrahedron.

[0033] In use, a person may put the present dental floss holder into the mouth and the shape/form of the holder makes it easy to guide the dental floss between the teeth by a combination of chewing on the holder and moving it around by using the tongue. The size of the dental floss holder is such that it can be put into the mouth and used in a comfortable manner.

[0034] Further embodiments of the invention are shown in FIGS. 2-4. The main difference between the embodiments is the number of supporting arms and consequently the number of strings of dental floss and thus the geometric shape of the holder.

[0035] A dental floss holder comprising eight floss supporting arms 1 is shown in FIG. 2. The multiple strings of dental floss are arranged to constitute the edges of a cube. In this specific embodiment, two strings of dental floss 6, 6 are aligned and arranged on opposite sides of the connecting section 4.

[0036] A dental floss holder comprising twelve floss supporting arms 1 is shown in FIG. 3 (the side view hides the four supporting arms which are mirror images of the four supporting arms extending towards the viewer). The multiple strings of dental floss are then arranged to constitute the edges of a polyhedron having 16 faces.

[0037] A dental floss holder comprising six floss supporting arms 1 is shown in FIG. 4. The multiple strings of dental floss are arranged to constitute the edges of an octahedron.

[0038] A dental floss holder comprising twelve floss supporting arms 1 is shown in FIG. 5. A strengthening section 8 is shown arranged between two of the neighboring supporting arms. Such strengthening sections may be arranged between any number of supporting arms provided they do not interfere with the insertion of the strings of dental floss between adjacent teeth.

[0039] Various alternatives regarding the shape or form of the floss supporting arms are shown in FIGS. 6a-f. The shape/form of the supporting arms may be varied in a multitude of ways, but they should be substantially longitudinal and comprise a fastening portion 7 to which a string of dental floss may be fastened. In the alternatives of FIGS. 6a and 6d, the fastening portion 7 is shown as a slight narrowing of the supporting arm close to the rounded surface 5, while in FIGS. 6b and 6c, the fastening portion 7 is shown as holes. In FIGS. 6e and 6f, the fastening portion 7 is shown as slots. The illustrated fastening portions 7 are especially useful in embodiments where the strings of dental floss may be replaced. In embodiments where the strings of dental floss are permanent (e.g. for single use) they may be attached to the fastening portion 7 by molding, melting, embedding or gluing. When the latter methods for attaching are used the fastening portion is not restricted to any shape or form, and may only denote a position on the supporting arm, at which position a string of dental floss is, or may be, attached.

[0040] An alternative feature of a dental floss holder according to the invention is shown in FIG. 7. In this case, a compressible material 9 is placed in the space between the strings of dental floss 6, the floss supporting arms and the connecting section, such that the compressible material 9 will help to push the strings of dental floss back out once inserted between adjacent teeth.

[0041] The dental floss holder according to the invention, excluding the strings of dental floss per se, may be manufactured in any suitable material such as metals and synthetic polymers having the required mechanical properties with regards to strength and flexibility/rigidity. A requirement of such materials is their suitability for oral use by humans. In view of the present disclosure, and known examples of materials used in prior art dental floss holders, the skilled person would easily find a number of materials fulfilling the required properties.

[0042] Preferably, the dental floss holder is manufactured in one piece by molding. In such manufacture, the attachment of the strings of dental floss may advantageously be performed during the molding process, or in a subsequent manufacturing step wherein the strings of dental floss are fastened by melting or gluing.
