BREVE EXPLICACIÓN DE LA INVENCIÓN BRIEF EXPLANATION OF THE INVENTION
La invención consiste en un cepillo de dientes que ofrece unas ventajas apreciables sobre el estado de la técnica. Su realización más básica viene definida en la reivindicación primera. The invention consists of a toothbrush that offers appreciable advantages over the state of the art. Its most basic embodiment is defined in the first claim.
Este cepillo de dientes es del tipo formado por un mango, con un asidero rígido y un cuello que puede ser flexible. En un extremo se dispone un cabezal de donde surgen cerdas por al menos dos lados opuestos, preferiblemente por todo el perímetro (360e), y, opcionalmente, en el extremo libre del cabezal. De la misma forma, es posible que surjan cerdas por el extremo del cabezal más próximo al cuello, ya sea en combinación con las del extremo libre o de forma independiente. This toothbrush is of the type formed by a handle, with a rigid handle and a neck that can be flexible. At one end there is a head from which bristles emerge from at least two opposite sides, preferably around the entire perimeter (360 e ), and, optionally, at the free end of the head. In the same way, it is possible that bristles emerge from the end of the head closest to the neck, either in combination with those of the free end or independently.
En una realización preferida, el cabezal es desmontable, ya sea de forma independiente o formando conjunto con el cuello. In a preferred embodiment, the head is removable, either independently or together with the neck.
Cuando las cerdas surgen por todo el perímetro, las cerdas pueden definir una envolvente cilindrica, prismática poligonal, prismática elíptica... Por envolvente se entiende la curva que circunscribe los extremos libres de las cerdas perimetrales. Es decir, ignorando las posibles cerdas del extremo libre del cabezal u orientadas hacia el cuello, que pueden ser poliédricas o semiesféricas u otras formas similares. When the bristles appear around the entire perimeter, the bristles can define a cylindrical envelope, polygonal prismatic, elliptical prismatic... By envelope we mean the curve that circumscribes the free ends of the perimeter bristles. That is, ignoring the possible bristles at the free end of the head or oriented towards the neck, which can be polyhedral or hemispherical or other similar shapes.
Por su parte, las cerdas pueden ser de diferentes tipos, independientes o combinados: sintéticas, de goma o caucho, orgánicas y/o biodegradables. For their part, the bristles can be of different types, independent or combined: synthetic, rubber, organic and/or biodegradable.
En una realización, el cepillo comprende cerdas de diferente longitud, generalmente de dos o más materiales diferentes, definiendo dos envolventes con forma igual o diferente. In one embodiment, the brush comprises bristles of different length, generally of two or more different materials, defining two shells with the same or different shape.
Todas estas realizaciones son combinables entre sí, obteniendo así un cepillo de dientes extremadamente versátil. All these embodiments can be combined with each other, thus obtaining an extremely versatile toothbrush.

MODOS DE REALIZACIÓN DE LA INVENCIÓN MODES OF EMBODIMENT OF THE INVENTION
Se procede a describir un ejemplo de la invención a partir de las figuras anteriores. Este ejemplo es orientativo, siendo las reivindicaciones quienes definen de forma inequívoca las características de la invención. We proceed to describe an example of the invention from the previous figures. This example is indicative, being the claims who unequivocally define the characteristics of the invention.
El cepillo de dientes de la figura 1 comprende un mango (1), que generalmente es anatómico y que puede tener un motor para girar el cabezal (2). El mango (1) representado tiene una primera parte rígida formando un asidero (1 a) y un cuello (1 b) que puede ser algo flexible. El mango (1) está rematado en el cabezal (2) que posee una serie de cerdas (3) por todo su perímetro. El cabezal (2) puede ser desmontable del mango (1 ), con o sin el cuello (1 b), para su sustitución por desgaste o cuando se necesita otro tipo de funcionalidades. The toothbrush in figure 1 comprises a handle (1), which is generally anatomical and which may have a motor to rotate the head (2). The handle (1) shown has a first rigid part forming a handle (1a) and a neck (1b). which can be somewhat flexible. The handle (1) is finished in the head (2) that has a series of bristles (3) around its entire perimeter. The head (2) can be detachable from the handle (1), with or without the neck (1 b), for replacement due to wear or when other types of functionalities are needed.
El cabezal (2) puede tener diferentes secciones (circular (figura 1), poligonal (hexagonal, pentagonal...), elíptica, pletina plana (figura 2) ...) siendo las cerdas (3) de la longitud adecuada en cada punto para que la envolvente del conjunto tome la forma deseada, que puede no corresponder a la forma de la sección del cabezal (2). En las figuras sólo se han representado las envolventes, por sencillez. The head (2) can have different sections (circular (figure 1), polygonal (hexagonal, pentagonal...), elliptical, flat platen (figure 2)...) with the bristles (3) of the appropriate length in each point so that the envelope of the assembly takes the desired shape, which may not correspond to the shape of the head section (2). In the figures only the enclosures have been represented, for simplicity.
En la figura 3 se aprecian varias formas de realización, en las cuales el cabezal (2) posee, o no, cerdas (3) en su extremo libre (4). De la misma forma, puede tener cerdas traseras (5) orientadas hacia el cuello (1b). Figure 3 shows various embodiments, in which the head (2) has, or does not have, bristles (3) at its free end (4). In the same way, it can have rear bristles (5) oriented towards the neck (1b).
Las cerdas (3) pueden ser de diferentes tipos, variando su rigidez y su dureza (capacidad de rayar y arrancar el sarro). Así, las cerdas (3) pueden ser sintéticas, de goma o caucho, orgánicas, biodegradables o de cualquier tipo conocido. Cada tipo de cerdas (3) puede tener longitud diferente, de forma que generan dos o más envolventes. The bristles (3) can be of different types, varying in stiffness and hardness (ability to scratch and remove tartar). Thus, the bristles (3) can be synthetic, rubber, organic, biodegradable or of any known type. Each type of bristles (3) can have a different length, so that they generate two or more envelopes.
Por ejemplo, en la figura 3 se aprecian seis ejemplos de realización, que pueden estar creados con cerdas (3) de uno o más tipos, y de una o más longitudes y formas de envolvente. Se aprecia como la envolvente puede tener forma prismática (figura 3A), cilindrica (de base circular o elíptica...), esférica... y con cerdas traseras (5) o en el extremo libre (4) del cabezal (2). For example, in figure 3 six examples of embodiment can be seen, which can be created with bristles (3) of one or more types, and of one or more lengths and wrapper shapes. It can be seen how the envelope can have a prismatic shape (figure 3A), cylindrical (with a circular or elliptical base...), spherical... and with bristles at the back (5) or at the free end (4) of the head (2) .
No se considera necesario representar todas y cada una de las opciones, por ser un número excesivo y ser todas evidentes para el experto en la materia a partir de esta descripción. It is not considered necessary to represent each and every one of the options, since there is an excessive number and they are all obvious to those skilled in the art from this description.
