FR2654314A1 - Autostable toothbrush with or without refillable integral reservoir for toothpaste or gel and with interchangeable or fixed brush - Google Patents

Abstract

Device for maintaining toothbrushes in a vertical position without outside assistance, with or without an integral reservoir of toothpaste or gel and with an interchangeable or fixed brush. The invention relates to a toothbrush handle having both a characteristic shape which can be an integral reservoir (11) for tooth gel or paste and housing a non-slip (5) ballasting device (10). This device, owing to the characteristic shape (4) which it confers on the handle of the toothbrush, makes it possible to incorporate a reservoir for dental products, and owing to the possible use of flexible material, makes it possible to expel the product towards the orifice (8) and to reintegrate the reservoir (11) with the toothpaste by interrupting the pressure of the fingers of the hand (17). This novel toothbrush system is intended for the general public and relates to the dental hygiene of adults and children.

Description

The present invention is a self-stable toothbrush for humans <FIG C) with or without gel reservoir (li) or built-in rechargeable dental paw and with a brush (FIG A)
interchangeable or fixed.

Traditionally, @ human toothbrushes, for example
their shape, if you are stable only when placed on a horizontal plane, or resting in "n" toothed glass a with the tube of toothpaste; which often gives the whole an unstable balance.

This new toothbrush, by the shape of its handle (4) which can be made in one piece with a reservoir of gel or dental paste (11), which handle (4) is weighted at its lower end (10 ) by a weight covered with a non-slip surface (5) or the weight (10) itself being made of non-slip materials, can keep a vertical position given the position of the center of gravity of said toothbrush.

In use, when the consumer rests his toothbrush on a flat surface at (10), said toothbrush oscillates around a vertical axis of equilibrium (18) before stabilizing.

Self-stable, the toothbrush thus becomes a real aesthetic object, and its swollen handle (FIG B) in flexible or rigid materials can, while keeping this flared shape in its lower part (4) have an external face with different shapes. (19). Thus, by way of nonlimiting example, the sketch
(FIG. B) corresponds to a handle whose external faces form a hexagonal segment along the cut (AA).

If the freestanding toothbrush is actually provided with the gel or dental paste reservoir (11), this must be made of flexible materials such as, for example, non-limiting rubber, in order to allow the dental product to be pushed from the reservoir (11) to the outlet (8) located between the brushes (6) via the conduit (9) of the brushing part (FIG A), before being expelled at (12).

This thrust is the consequence of the pressure exerted by the fingers of the hand (17) holding the handle (FIG B) and compressing the flexible reservoir (11) and its envelope (19). Once the pressure (17) has ended, the, the handle (4) resumes its initial swollen shape and the dental product is sucked into the reservoir (11) by air intake.

This system allows a dosage of the dental product during tooth cleaning.

The upper part carrying the brush (FIG A) can be removable and detached from the handle tFIG B) so that it can be replaced. It is for this purpose that the lower part of the brushing part (FIG A) is threaded in (2) allowing a screwing of the latter (FIG A) in the orifice (3) also fi Thrown the handle (FIG B ) in order to receive the brushing part and allow a perfect junction between FIG A and FIG B.

According to a variant not illustrated, and for reasons of cost and market constraints, this self-stable toothbrush may not be separated between the brushing part (FIG
A) and the handle (FIG B). In this case, the two parts (FIG
Ai and (FIG B) form a single block and the toothbrush becomes non-refillable and disposable.

A front view of the part (1) in the figure (FIG E) shows the possible arrangement of the brushes (16) in the middle of which
The outlet (8) for the dental product can be placed.

For hygienic measures, an ultralight protective envelope (7) and detailed in (FIG D) protects the brushes from part (1) and closes with a system of clips (13), and the two parts of the shell ( 14) are interconnected in (15).

By way of nonlimiting example, the sketch (FIG D) mentions shells with octagonal segments but these shells can have different shapes.

This self-stabilizing toothbrush becomes a real object of decoration, and although keeping this swollen shape characteristic of the invention, the outer envelope (19), in the formula without a loaded integrated reservoir, can take on different aspects, and can be made of multiple materials, even rigid ones like gold or any other precious material.

By way of nonlimiting example, the self-stabilizing toothbrush with integrated reservoir has smaller dimensions especially for children.

Claims (4)

1. Self-stable toothbrush, characterized in that its handle (4) of flared shape down, is ballasted at its lower end (10) by a weight covered with an anti-slip surface (5X or the weight (10) itself being made of non-slip materials. 2. Toothbrush according to claim 1, characterized in that it further comprises a light envelope (7) protecting the head (1) of the brush, formed of two shells (14) connected together by one on their side (15) and closed together by the other side using a clip system (13). 3. Toothbrush according to claim i or 2, characterized in that it is in one piece or in two parts connecting by screwing (2,3). 4. Toothbrush according to one of claims 1 to 3, characterized in that a reservoir (11) of dental paste or gel with an envelope of flexible materials, notably rubber, is arranged in the lower part of the handle, above the ballast weight, this tank communicating with an outlet orifice (8) located between the brushes (6) via a conduit (9).
