Abstract

Device for hygienization of an implement (1) for oral hygiene having at least one head (11) and a handle (12) for cleaning teeth, the hygienization device comprising a casing (3) having a cavity complimentary to the head (11) of the implement (1) and at least one internal part (31) made of silver or silver-coated in contact with the head (11) in order to transfer ions released from the internal part (31) of the head (11).

Description

Field of the invention

The present invention refers to a hygienization device for an oral hygiene implement.

State of the art

Tooth-brushes are well-known.
Pipe cliners are additional devices for cleaning the interdental spaces between the teeth. This is an oral hygiene implement consisting of a handle and a rigid metal wire with a series of bristles arranged in a 360° radial pattern with respect to the rigid wire, with diameter increasing towards the handle or the junction of the rigid wire to the handle. Arranged all around, the bristles are capable of cleaning and removing food residues from the interdental spaces, under fixed bridges, under the fixed prosthetics on implants, and under the fixing bars of dental prosthetics. Tooth-brushes having a portion of the brush made of silver or in any case silver-coated, are also known. For example, one known brush comprises a support for the bristles that is made of silver.
The reasons for using silver reside in the fact that, in contact with water, silver releases active ions that attack bacteria, thus achieving an antibacterial function. The head of said brushes can be replaced when the bristles are consumed or deformed, but this is costly.

Summary of the invention

The scope of the present invention is to provide a hygienization device for an oral hygiene implement that can be reused independently of the lifetime of the consumable parts of such implements.
A subject of the present invention is a hygienization device for an oral hygiene implement in compliance with claim 1.
According to one preferred embodiment of the invention, ions are transferred indirectly to the head of the toothbrush or the pipe cliner by means of a vector liquid retained by a sponge that is essentially interposed between the head of the implement and the silver-coated part.
Another scope of the present invention is to present a system comprising an pipe cliner and a hygienization device for the head of the pipe cliner.
Said device is particularly applicable for travel pipe cliners.
A further scope of the present invention is to present a system comprising a toothbrush and a hygienization device for the head of said toothbrush.
Said device is particularly applicable for travel toothbrushes.
Another scope of the present invention is to propose hygienization methods for the head of a toothbrush or pipe cliner.
Toothbrush or pipe cliner head hygienization methods, as described more precisely in the claims, are also a subject of the present invention.
The claims describe preferred embodiments of the invention, forming an integral part of the present description.

Detailed description of one preferred embodiment of the invention

According to the present invention, a hollow casing 3 is adapted to enclosing the head of an implement 1 intended for every day oral hygiene, such as a toothbrush or an pipe cliner, at least when said implement is not being used. In other words, said casing is such that the head 12 of the implement can be inserted therein. Said casing essentially defines a cap or cover for at least the head of the implement 1.
Said casing comprises a silver or silver-coated element 31 inside the cavity.
The head may be that of a toothbrush, i.e. essentially flat and having natural or synthetic bristles attached to one of the two faces of the head, or with the bristles arranged radially around a rigid conical-shaped or cylindrical core.
According to one preferred variant of the invention, with the insertion of the head 12 into the casing 3, the bristles are in direct contact with said silver or silver-coated part 31. The bristles, previously wet or humid, typically after each use of the implement, are capable of releasing ions from the silver element 31, thus remaining sanitized. Therefore, the casing size is designed so that the bristles are in direct contact with the silver part.
According to one preferred embodiment of the invention, the casing is adapted to retain a vector liquid at least while the head 11 of the toothbrush or pipe cliner is inserted therein, so that said liquid allows the release of active ions from the silver, contributing towards the hygienization of the head 11 of the toothbrush or pipe cliner. Said liquid may be, for example, water or a mouthwash or a disinfectant suitable for the present purpose of hygienization of the head 3 by means of ions.
In this sense, both variants comprise means adapted to transferring ions released from said internal part 31 to said head 11.
According to the variants reported in figures 3 - 5, the interior of the casing 3 contains a sponge 2, preferably pliable and shaped so as to be complimentary to the shape of the head 11 of the implement 1.
Said sponge may be advantageously soaked in water or mouthwash or another suitable disinfectant, as above, acting as the vector liquid.
This variant is that ensuring the best performance of the device, especially when coupled with an pipe cliner, in that the latter possesses bristles that are shorter on average than a toothbrush and that therefore tend to become less deformed due to contact with the sponge.
According to the variant of figure 3, the portion of the casing is at least partially silver coated, defining a layer of silver 31, preferably achieved by means of a galvanic process. Or alternatively, a plate, figure 4, of silver coated material may be placed inside the cavity of the casing 3. Said sponge may contribute to maintaining the position of said plate. According to the variant of figure 5, the sponge may be made by incorporating the silver or silver coated component 31, for example a small pellet.
Advantageously, the deterioration and replacement of the head 11 does not involve the replacement of a silver coated part.
Figure 6 represents a preferred example embodiment of the device wherein an pipe cliner 1 with a straight head 11, i.e. essentially aligned with the longitudinal development of the related handle 12, comprises a cap 3, similar to that represented in figure 3, that engages over the head of the pipe cliner 1 until it partially locks with the handle 12 of the pipe cliner. In this case, the cap 3 may also be liquid-tight.
One of the advantages of using a sponge inside the cover 3 is that of not necessarily having to use a hermetic seal on the cover, in that the vector liquid for the ions is held within the sponge.
Another advantage is that hygienization of the head 11 of the implement 1 occurs over a much longer time compared to that for toothbrushes of the known art, in that, both the presence of the sponge, and the closure of the cover over the body of the toothbrush or pipe cliner do not allow evaporation of the vector liquid, whereby it remains wet, even for days.
According to another aspect of the invention, the antibacterial effect of the ions is combined with the effect of the mouthwash, which plays both its own role as mouthwash and that of vector liquid for the ions released from the silver. Therefore, it is certainly very advantageous to use a mouthwash or a suitable disinfectant/antibacterial agent as vector medium for the ions.
The same principle may be used for any suitable oral hygiene implement, independently of the shape of the body of said implement, in that it is not strictly necessary that the cover 3 closes over the body. That which is of primary importance is that the head 11 of the implement 1 is in direct or indirect contact with the silver coating by means of the vector liquid, in order to achieve hygienization by the ions released from the silver part 31 contained inside the cover 3.
It is preferable that the sponge 3 be removable so as to be able to be easily rinsed and wrung out, for easier maintenance of the device. To this end, it may be fixed to the cover permanently or reversibly, by means of a retaining ring for example, not represented, or in any other way.
Said silver or silver coated part 31 may in turn be removable from the cover, should it be necessary to replace the cover or should it be necessary to replace said silver coated part 31.
According to another preferred variant of the invention, the cover is made from at least partially flexible material, so that the sponge can be rinsed and wrung out without its removal from the cover. In this case, the role played by the cover 3 is limited to preventing the moisture contained in the sponge from being released. This indeed would constitute a problem for travel implements, which could, for example, be kept in a pocket.
Therefore, this solution is best applied to travel toothbrushes and pipe cliner.
The elements and the characteristics illustrated in the various preferred embodiments can be used in combination together, without however deviating from the scope of protection of the present patent application.
