Compresa higienica
Esta divulgacion esta relacionada con un producto de higiene femenino y mas concretamente con una compresa higienica.
En referencia a la Fig. 1, se muestra una compresa higienica convencional 1 para incluir un sustrato 11 que esta formado con dos solapas laterales 111, y un cuerpo absorbente 12 que esta montado de modo que sea protuberante sobre el sustrato 11.
El uso del cuerpo absorbente 12 que esta montado de modo que sea protuberante sobre el sustrato 11 permite que la compresa higienica 1 entre en contacto de manera ajustada con la piel del usuario de manera que absorba rapidamente las secreciones, asi como para que evite que se sufra una perdida delas secreciones de la compresa higienica. Debido a que el cuerpo absorbente 12 mantiene un estrecho contacto con el sustrato 11, asi como a que cuando se utiliza el cuerpo absorbente 12 tambien se ajusta estrechamente contra la piel del usuario, la compresa higienica 12, por tanto, presenta poca permeabilidad al aire. La utilizacion de la compresa higienica convencional durante un largo periodo de tiempo puede que cause la emision de olores extranos, asi como que la comodidad de su uso tambien se vea negativamente afectada.
El documento de patente US 2014/358106 A1 divulga una compresa higienica que se compone de una serie de canales en relieve que son visibles cuando se mira a la compresa desde la superficie que se orienta hacia el usuario.
El documento de patente 2003/153232 A1 divulga un articulo absorbente que se compone de fibras de celulosa que estan presentes al menos de manera parcial en forma de granulos.
Por lo tanto, un objetivo de esta divulgacion es proporcionar una compresa higienica que pueda mitigar al menos uno de los inconvenientes del estado anterior de la tecnica.
La invencion proporciona una compresa higienica de conformidad con la reivindicacion numero 1.
De conformidad con esta divulgacion, la compresa higienica incluye: un sustrato que tiene una capa de base y un cuerpo absorbente que esta montado de modo que sea protuberante sobre la capa de base, y que define un sentido longitudinal y un sentido del ancho que es perpendicular al sentido longitudinal; y al menos una unidad absorbente que incluye una pluralidad de secciones de conexion que estan conectadas al cuerpo absorbente del sustrato y que estan separadas entre si en el sentido longitudinal, una seccion absorbente que se extiende a lo largo del sentido longitudinal y que esta conectada a las secciones de conexion, y una pluralidad de pelusas de algodon que estan colocadas sobre la seccion absorbente. El cuerpo absorbente del sustrato, las secciones de conexion y la seccion absorbente definen de manera conjunta una pluralidad de canales de aireacion donde cada uno de ellos se extiende a lo largo del sentido del ancho.

Antes de que se describa la divulgacion con mayor detalle, cabe senalar que cuando se ha considerado oportuno, se han repetido numeros de referencia o partes terminales de los numeros de referencia entre las figuras para indicar elementos correspondientes o analogos, los cuales puede que opcionalmente tengan caracteristicas similares.
En referencia a las Figs. que van de la numero 2 a la numero 4, se muestra una primera realizacion de una compresa higienica 2 de conformidad con la divulgacion con el fin de incluir un sustrato 3 y una unidad absorbente 4 que tiene la forma de una capa.
El sustrato 3 tiene una capa de base 31 y un cuerpo absorbente 32 que esta montado de modo que sea protuberante sobre la capa de base 31, y define un sentido longitudinal (X) y un sentido del ancho (Y) que es perpendicular al sentido longitudinal (X).
La unidad absorbente 4 incluye una pluralidad de secciones de conexion 41 que estan conectadas al cuerpo absorbente 32 del sustrato 3 y que estan separadas entre si en el sentido longitudinal (X), una seccion absorbente 42 que se extiende a lo largo del sentido longitudinal (X) y que esta conectada a las secciones de conexion 41, y una pluralidad de pelusas de algodon 45 que estan colocadas sobre la seccion absorbente 42. Dicho de otro modo, la seccion absorbente 42 esta conectada al cuerpo absorbente 32 del sustrato 3 a traves de las secciones de conexion41. La seccion absorbente 42 podriaestar formada por partes donde cada una de ellas tiene una forma arqueada. El cuerpo absorbente 32 del sustrato 3, las secciones de conexion 41 y la seccion absorbente 42 definen de manera conjunta una pluralidad de canales de aireacion 44 donde cada uno de ellos se extiende a lo largo del sentido del ancho (Y).
La unidad absorbente 4 esta formada con una pluralidad de perforaciones 43. Todas estas perforaciones estan separadas entre si, se extienden a traves de la seccion absorbente 42 y estan colocadas en comunicacion fluidacon los canales de aireacion 44. Dicho de otro modo, una pluralidad de perforaciones 43 se extienden a traves de la seccion absorbente 42 y estan colocadas en comunicacion fluida con los canales de aireacion 44 que estan formados debajo de la pieza absorbente 42.
Cabe senalar que dos extremos opuestos de la unidad absorbente 4 en el sentido longitudinal (X) podrian estar conectados con el cuerpo absorbente 32 o separados de el. En esta realizacion, los dos extremos opuestos de la unidad absorbente 4 estan separados del cuerpo absorbente 32.
En esta realizacion, la seccion absorbente 42 y la pluralidad de pelusasde algodon 45 que estan colocadas sobre la seccion absorbente 42 proporcionan los efectos de absorcion y de difusion de las secreciones, y las perforaciones 43 y los canales de aireacion 44 mejoran la permeabilidad al aire de la compresa higienica 2 con el fin de evitar que se generen olores extranos, asi como para potenciar la comodidad de su uso.
En referencia a las Figs. que van de la numero 5 a la numero 7, se muestra una variacion de la primera realizacion que es casi identica a la primera realizacion, donde la diferencia reside en que la seccion

absorbente 42 se extiende a lo largo del sentido longitudinal en forma de ola, con picos que sobresalen por fuera del cuerpo absorbente 32 del sustrato 3 y con valles que estan marcados hacia el cuerpo absorbente 32 del sustrato 3. En esta variacion de la primera realizacion, las Figs. 6 y 7 ilustran que los dos extremos opuestos de la unidad absorbente 4 estan conectados al cuerpo absorbente 32.
La unidad absorbente 4 podria incluir tambien una pluralidad de filas de bolas de pelusa de algodon (las cuales no se muestran) que esten colocas sobre la seccion absorbente 42, y los diametros de las bolas de pelusa de algodon en una de las filas son diferentes de los diametros de las bolas de pelusa de algodon en una fila contigua de entre todas las filas.
Las bolas de pelusa de algodon potencian el efecto de absorcion y de difusion de las secreciones. Ademas, debido a que los diametros de las bolas de pelusa de algodon en dos filas contiguas cualquiera son diferentes, hay muchos huecos entre las bolas de pelusa de algodon 46, lo que mejora la permeabilidad al aire con el fin de evitar que se generen olores extranos y que de ese modo se potencie la comodidad de su uso.
En referencia a la Fig. 8, una segunda realizacion de una compresa higienica 2 de conformidad con esta divulgacion incluye un sustrato 3 y una pluralidad de unidades absorbentes 4 que estan separadas entre si a lo largo del sentido del ancho (Y). Cada una de las unidades absorbentes 4 tiene una forma de banda alargada y se extiende a lo largo del sentido longitudinal (X).
En la segunda realizacion, cada una de las unidades absorbentes 4 incluye una pluralidad de secciones de conexion 41 que estan conectadas al cuerpo absorbente 32 del sustrato 3 y que estan separadas entre si en el sentido longitudinal (X), una seccion absorbente 42 que se extiende a lo largo del sentido longitudinal (X) y que esta conectada a las secciones de conexion 41, y una pluralidad de pelusas de algodon 45 que estan colocadas sobre la seccion absorbente 42. La seccion absorbente 42 de cada una de las unidades absorbentes 4 podria estar formada por partes donde cada una de ellas tiene una forma arqueada. Las secciones de conexion 41 y la seccion absorbente 42 de cada una de las unidades absorbentes4 cooperan con el cuerpo absorbente 32 del sustrato 3 para definir una pluralidad de canales de aireacion 44 donde cada uno de ellos se extiende a lo largo del sentido del ancho.
Gracias a que las unidades absorbentes 4estan separadas a lo largo del sentido del ancho (Y) y a los canales de aireacion 44, la compresa higienica 2 ha mejorado la permeabilidad al aire con el fin de evitar que se generen olores extranos, asi como para potenciar la comodidad de su uso. Asimismo, como la pluralidad de pelusas de algodon 45 estan colocadas sobre la seccion absorbente 42, la compresa higienica 2 podria ajustarse estrechamente a los genitales del usuario con el fin de mejorar las propiedades de absorcion y de difusion.
Cabe senalar aqui que los dos extremos de cada una de las unidades absorbentes 4 podrian estar conectados al cuerpo absorbente 32 del sustrato 3, asi como tambien podrian estar configurados para estar separados del sustrato 3.
En referencia a las Figs. 9 y 10, se muestra una tercera realizacion de una compresa higienica 2 de conformidad con esta divulgacion que, en general, es identica a la segunda realizacion y solo difiere de ella en que: cada una de las unidades absorbentes 4 tambien incluye una pluralidad de bolas de pelusa de algodon 46 que estan colocadas sobre la seccion absorbente 42, y los diametros de las bolas de pelusa de algodon 46 sobre una de las unidades absorbentes 4 son diferentes de los diametros de las bolas de pelusa de algodon 46 sobre una unidad contigua de entre todas las unidades absorbentes 4.
Esta realizacion podria conseguir los mismos efectos que la segunda realizacion. Debido a que los diametros de las bolas de pelusa de algodon 46 sobre dos unidades absorbentes 4 contiguas cualquiera son diferentes, existen muchos huecos entre las bolas de pelusa de algodon 46, lo que mejora la permeabilidad al

aire con el fin de evitar que se generen olores extranos y que de ese modo se potencie la comodidad de su uso.
En referencia a las Figs. 11 y 12, se muestra una cuarta realizacion de una compresa higienica 2 de conformidad con esta divulgacion que, en general, es identica a la primera realizacion, y solo difiere de ella en que: las secciones de conexion 41 estan colocadas en dos filas que se extienden en el sentido longitudinal (X), y la seccion absorbente 42 tiene dos secciones de conexionplisadas 47 que estan separadas entre si a lo largo del sentido del ancho (Y) y que se extienden en el sentido longitudinal (X), y una pieza absorbente (49). Cada una de las secciones de conexionplisadas (47) interconecta la pieza absorbente (49) con una fila respectiva de las dos filas de las secciones de conexion (41). El cuerpo absorbente (32) del sustrato (3), las secciones de conexion (41), las secciones de conexionplisadas (47) y la pieza absorbente (49) definen de manera conjunta los canales de aireacion (44) donde cada uno de ellos se extiende a lo largo del sentido del ancho (Y) y un canal de ventilacion (48) que se extiende a lo largo del sentido longitudinal (X) y que se encuentra en una comunicacion espacial con los canales de aireacion (44). Esta realizacion podria conseguir los mismos efectos que la primera realizacion y tambien podria proporcionar una permeabilidad al aire mejorada con el fin de potenciar la comodidad de su uso.
En resumen, gracias a la seccion absorbente 42 que esta conectada al cuerpo absorbente 32 del sustrato 3, asi como a los canales de aireacion 44, la compresa higienica 2 presenta una permeabilidad al aire superior con el fin de evitar que se generen olores extranos y que de ese modo se potencie la comodidad de su uso.
En la descripcion anterior, a los efectos de esta explicacion, se han expuesto numerosos detalles especificos con el fin de proporcionar un conocimiento integral de la realizacion. No obstante, para cualquier experto en la materia sera evidente que una o mas realizaciones se podrian practicar sin algunos de estos detalles especificos. Cabe apreciar tambien que la referencia que se ha hecho a lo largo de esta memoria descriptiva a “una realizacion”, a una realizacion con la indicacion de un numero ordinal y asi sucesivamente, significa que un distintivo, una estructura o una caracteristica en particular se podria incluir en la practica de la divulgacion. Cabe apreciar tambien que en la descripcion a veces se agrupan varias caracteristicas dentro de una sola realizacion, figura o descripcion de dicha descripcion con el proposito de optimizar la divulgacion y de ayudar a comprender los diversos aspectos inventivos.
