Description

Device for cleaning teeth containing a dental floss

Technical Field

The invention concerns a device for cleaning teeth containing a dental floss holder with two forked arms for manual fixing the dental floss, which holder may be integrated with a toothbrush into one functional unit.

Background Art

For the oral hygiene, there is at present most often used a toothbrush alone. Only a small percentage of population proceeds also to the next phase of oral hygiene, which is final cleaning of interdental spaces by a dental floss, produced as one piece of several meters length. It may be wound into a ball or on a bobbin, of which the necessary piece, usually of 15 to 25 cm length, is unwound, wound around index fingers of both hands and stretched between them.

This method of using dental floss requires considerable manual skill and is time consuming, thus causing, especially to elderly people or people having thicker and shorter fingers, problems with manipulation in the mouth, discouraging them from regular use of dental floss. Moreover, this fact discourages from using dental floss also a further part of population - the very busy part.

In case of separate dental floss holders, the floss is wound on the floss holders, but this method is relatively complicated and impractical.

These disadvantages are partially eliminated by the manual device for teeth cleaning according to US 2006/0011211 A1 , which consists of a handle, a floss holder and a bobbin for winding the floss. Nevertheless, the device is mechanically relatively complicated and structurally robust and it is a single-purpose device, so that it has not won recognition in practice. Similar principle is used also by other devices for teeth cleaning with a holder and a floss dispenser (WO 03/043523; US 2006/0011212 A1 ; US 2005/0279379 A1 ; DE 103 57 838 A1 ; WO 2004/006800), some of them even with electrical driving mechanism (GB 2 402 341 A). Although manipulating the said devices in a mouth is simpler compared with manipulating the floss alone in a mouth, a disadvantage is a relatively complicated construction and, consequentially, rather high costs, resulting in small interest in these devices. A further disadvantage is also the fact that the dental floss in the dispenser within the handle comes into contact with water, when rinsing the holder, in consequence of which hygienic conditions for the floss cannot be guaranteed.

The aim of the present invention is to provide such device for teeth cleaning which eliminates persistent problems with using dental floss and allows to its user comfortable and, therefore, massive using.

Disclosure of Invention

The above aim is achieved by a device for teeth cleaning containing a dental floss holder, the subject-matter of which consists in that it consists of a handle, provided at one of its ends with a holder with forked arms for manual attaching the dental floss, and at the other end with a toothbrush. The toothbrush is detachably attached to the handle, for example by a lock-matrix and lock-patrix, or it forms one functional unit with the handle. The forked holder arms may be preferably twice broken or possibly slightly goosenecked.

The forked holder arms are provided at their ends with a clamping mechanism for clamping the dental floss, wherein the clamping mechanism may preferably be formed by unilaterally closed tunnels, which have at their vault top a longitudinal groove with guiding notch or noses, preferably spikes in the form of arrowy projections which continuously merge into the guiding notches. Alternatively, manual attaching the dental floss may be achieved by solid embedding the dental floss into the arms, so that the holder arms have no clamping device.

The dental floss, produced all of a piece, contains clamping elements, which simultaneously serve as dividing elements and allow clamping the floss in the clamping mechanism of forked holder arms. These elements divide the dental floss into regular working sections which are longer, and shorter connecting sections in which individual working sections will be separated (cut or trimmed off) from the dental floss before use. The working sections, delimited at both ends by the clamping elements, correspond in their length to the width of the span between both forked holder arms with clamping mechanisms and the clamping element shape corresponds to the clamping mechanism type. - ό -

The clamping elements may be three-dimensional or two-dimensional. Three-dimensional clamping elements exhibit preferably the shape of a ball, a cone, a teardrop or a pyramid, possibly also other suitable derived shapes. Two- dimensional (flat) clamping elements have preferably a shape of a loop, a ring, a square, a triangle, or possibly another shape, and they form a fixing "eye" for fixing to the clamping mechanism of the forked holder arm, formed by a nose, possibly having a shape of an arrowy projection.

The dental floss is alternatively made so that the working sections, delimited at both ends by the clamping elements, form separate pieces (prefabricated elements) ready to be fixed to the arms of the forked holder, which is especially advantageous for prefabricated elements with clamping elements having the shape of loops which are made directly from the material of the dental floss.

Naturally, the clamping elements of the dental floss are made of hygienically suitable material like, for example, polyvinylchloride (PVC), polypropylene (PPR), polyethylene (PET) and others, or they may be made directly of the dental floss material (above mentioned clamping elements in the form of loops).

The device for teeth cleaning containing at one end a holder with forked arms for manual attaching the dental floss and at the other end a toothbrush, is one functional unit, where after performing basic oral hygiene with the toothbrush one can continuously proceed to cleaning of interdental spaces by dental floss, which is provided with clamping elements, by simple attaching it to clamping mechanisms of the forked holder arms.

At the ends of the forked arms of the dental floss holder, there are located clamping mechanisms serving for attaching and fixing the clamping elements of the dental floss. They are formed by unilaterally closed tunnels, which are at their vault top interrupted by a longitudinal groove which continuously passes up to the ends of the forked holder arms with clamping mechanisms and there it forms a guiding notch for the dental floss with clamping elements, which notch directs the dental floss from one forked holder arm to the other one.

Method of clamping the dental floss with clamping elements is such that one end of the dental floss with a clamping element is inserted into the tunnel of the first forked holder arm so that the dental floss is guided through the groove and guiding notch out towards the second arm. The second forked holder arm will be W - -

pressed into the spring-loaded position N. towards the first arm so that the clamping element of the second end of the dental floss can be inserted into the tunnel of the second forked holder arm and, after subsequent releasing, this arm returns by its own elasticity into its basic position |, thus stretching the floss guided through the grooves and notches between the forked holder arms.

In another preferred embodiment, spikes in the form of arrowy projections may be used as the clamping mechanism for the dental floss with clamping elements, the shape of which corresponds to the shape of dividing-fixing elements of the dental floss in the form of loops.

When using the clamping mechanism version in the form of arrowy projections (spikes), the clamping method is essentially identical; there is a difference only in the way of attaching the clamping elements, which are fixed by getting caught by the arrowy projections (spikes) of the forked holder arms.

To exclude fully the manipulation with clamping the dental floss in the forked holder arms, in another preferred type of embodiment the dental floss holder is made as a whole, disposable, replaceable holder with a connecting lock. The dental floss is here fixed directly by embedding it in its forked arms, while the disposable holder is only slipped on the connecting lock at the end of the toothbrush handle or a separate handle.

In all above types of clamping mechanisms (unilaterally closed tunnels, arrowy projections - spikes, disposable prefabricated part of the dental floss holder), the dental floss holder may be made so that at the handle end it is equipped with detachable toothbrush head with a connecting element and thus, it may be used also as a separate tool with its own handle.

An advantage of the device according to the present invention is the fact that it simplifies manipulation of the dental floss, but especially the fact that by joining the dental floss holder with the toothbrush into one functional unit, cleaning of interdental spaces becomes automatic and natural activity, following the toothbrush use. An advantage consists also in that any type of toothbrush head may be used.

The dental floss with prefabricated elements may be produced either as a whole, wherein the arrangement of prefabricated elements (clamping elements) divides it into so called working sections, corresponding in their length to the width - O - of the span between the forked holder arms, or individual working sections are separate pieces, provided with prefabricated parts.

Examples of invention embodiments

A device (Fig. 1 , 2) for teeth cleaning consists of a handle 2, which is at one end provided with a holder with forked arms 3 and at the other end with a head of toothbrush ±. The forked holder arms 3, between which dental floss 4 is stretched, are twice broken (Fig. 2) or slightly goosenecked (Fig. 1). Both ends of the forked arm 3 of the dental floss holder are provided with clamping mechanism in the form of a unilaterally closed tunnel. A detailed view of tunnel 5 is shown in Figs. 5 and 7.

As obvious from Fig. 7, the tunnel is at its vault top interrupted by a longitudinal groove 9, which continuously passes up to the end of the forked arm of the dental floss holder and there it forms a guiding notch IQ for dental floss 4 with clamping element 6 (Figs. 7 and 5).

Dental floss 4 to be clamped in the clamping mechanisms of the forked holder arms, made as a whole (Figs. 10 to 14), is divided by the clamping elements into longer working sections 4J. and shorter connecting sections 42. The clamping element shape on the dental floss corresponds to the clamping mechanism type on the forked holder arm, in which the dental floss will be clamped.

When using a clamping mechanism in the form of a unilaterally closed tunnel, the method of clamping the dental floss is such that one end of the dental floss with a clamping element (either in the form of a ball QΛ_, Fig. 10, or in the form of a cone QJZ, Fig. 11 , a cylinder 6^3, Fig. 12, a teardrop (xA, Fig. 13, or in the form of a pyramid 6J5, Fig. 14) is inserted into the unilaterally closed tunnel of the first forked holder arm in such a way that the dental floss is led out through the longitudinal groove (Fig. 7) and the guiding notch towards the second arm (Fig. 5). The second forked arm will be pressed into a spring-loaded position towards the first arm so that the clamping element 6 of the second end of the dental floss can be inserted into the unilaterally closed tunnel of this second arm. After subsequent releasing, the arm returns into its basic position, thereby stretching the floss guided through the longitudinal grooves and guiding notches between the forked holder arms (Fig. 5).

In another preferred embodiment (Fig. 6), the clamping mechanisms are formed by noses 7, the shape of which corresponds to the shape of a clamping element of the dental floss in the form of a loop 8 (for example arrowy projections - spikes).

When using clamping mechanism formed by noses 7 in the form of spikes, the method of clamping the dental floss is such (Fig. 6) that one end of the dental floss with a two-dimensional (flat) clamping element (either in the form of a loop 8, Fig. 15, or in the form of a ring 8J_, Fig. 16, a square 8^2, Fig. 17, a triangle 8^3, Fig. 18, or in the form of an oval 8,4, Fig. 19) is caught by the arrowy projection - a spike of the first forked holder arm so that the dental floss is led out through the longitudinal groove and guiding notch towards the second forked arm. The second arm will be pressed into a spring-loaded position towards the first arm so that the loop of the second end of dental floss can be slipped over the spike of the second arm. After subsequent releasing, the arm - as in the previous case - returns into its basic position, thereby stretching the floss guided through the longitudinal grooves and guiding notches between the forked holder arms (Figs. 6, 8, 9).

To exclude fully the manipulation with clamping the dental floss 4, in a further solution (Fig. 3), the dental floss holder is made as a whole, disposable, replaceable dental floss holder with a connecting lock-matrix 12 so that the ends of dental floss 4 are directly (solidly) embedded in its forked arms 3, and the holder is then only slipped onto the connecting lock-patrix 1_3 at the end of handle 2. This means that the clamping mechanism is replaced by solid connection of the forked holder arms with the dental floss.

In all types of clamping mechanisms, but also in an alternative without a clamping mechanism, the holder of the dental floss (Fig. 4) may be provided at the end of handle 2 with a connecting lock-matrix 12, into which a releasable head of toothbrush 1 with connecting lock-patrix 13 is slid, thus forming - after removing the releasable head of toothbrush 1 - a separate tool with its own handle 2.

A device for teeth cleaning according to the present invention, formed by a dental floss holder connected with a toothbrush or as a separate tool with its own handle, may considerably contribute to more efficient performing of oral hygiene, _ _

simply said to "teeth cleaning", and thus to caries prevention and to increasing dentition quality.
