El objeto de la presente invención recae, en un filtro para tabaco, es decir, del tipo que se utiliza, ya sea en cigarrillos fabricados industrialmente o para liar cigarrillos manualmente, con el objetivo de filtrar partículas tóxicas del humo que dichos cigarrillos desprenden al quemarse para hacerlo menos nocivo para el fumador, el cual, en lugar de estar fabricado con estopa a base de acetato de celulosa, que tarda mucho tiempo en degradarse, está fabricado en un material hidrosoluble, concretamente un material basado en Alcohol de polivinilo o PVA, con lo cual se solventa el problema medioambiental de las colillas de cigarrillos con filtro convencional. The object of the present invention falls on a tobacco filter, that is, of the type that is used, either in industrially manufactured cigarettes or for rolling cigarettes manually, with the aim of filtering toxic particles from the smoke that these cigarettes give off when burned to make it less harmful to the smoker, which, instead of being made with tow based on cellulose acetate, which takes a long time to degrade, is made of a water-soluble material, specifically a material based on polyvinyl alcohol or PVA, This solves the environmental problem of cigarette butts with a conventional filter.
CAMPO DE APLICACIÓN DE LA INVENCIÓN FIELD OF APPLICATION OF THE INVENTION
El campo de aplicación de la presente invención se enmarca dentro del sector de la industria dedicada a la fabricación de tabaco, centrándose particularmente en el ámbito de los filtros para cigarrillos, abarcando tanto los que se comercializan ya incluidos industrialmente en los cigarrillos como los que se comercializan de manera independiente para liar cigarrillos manualmente. ANTECEDENTES DE LA INVENCIÓN The field of application of the present invention is framed within the sector of the industry dedicated to the manufacture of tobacco, focusing particularly on the field of filters for cigarettes, encompassing both those that are commercialized already included industrially in cigarettes and those that are They market independently to roll cigarettes manually. BACKGROUND OF THE INVENTION
Actualmente, la materia prima para la manufactura de los filtros de cigarrillo es la celulosa (obtenida de la madera). La celulosa es acetilada (esto es convirtiéndola en un material llamado acetato de celulosa o simplemente "acetato" para abreviar), disuelta, e hilada como fibras sintéticas continuas ordenadas en un atado llamado estopa. Esta estopa es abierta, plastificada, se le da forma, y se corta a una longitud adecuada para actuar como un filtro. Currently, the raw material for the manufacture of cigarette filters is cellulose (obtained from wood). Cellulose is acetylated (this is by turning it into a material called cellulose acetate or simply "acetate" for short), dissolved, and spun as continuous synthetic fibers arranged in a bundle called tow. This tow is open, plasticized, shaped, and cut to a length suitable to act as a filter.
El problema es que, teniendo en cuenta que en todos los países del mundo se fuma, las colillas, que son la parte del cigarrillo que contiene el filtro y es lo que queda tras su consumo, se tiran y son el principal residuo recogido en el medio ambiente mundial, con millones de kilos diseminados por todo el planeta. Estos desechos de los cigarrillos, aunque el papel se deshace enseguida, los filtros pueden tardar décadas en desaparecer y contaminan los mares, dañan la biodiversidad o pueden provocar incendios forestales. The problem is that, taking into account that in all the countries of the world it is smoked, butts, which are the part of the cigarette that contains the filter and is what remains after its consumption, are thrown away and are the main residue collected in the global environment, with millions of kilos scattered across the planet. These cigarette wastes, although the paper soon disposes, filters can take decades to disappear and pollute the seas, damage biodiversity or can cause forest fires.
El objetivo de la presente invención es, pues, proporcionar una solución a dicha problemática mediante el desarrollo de un nuevo tipo de filtro fabricado en un material que, sin dejar de cumplir su función protectora durante el quemado del tabaco para el fumador, se deshaga rápidamente y, en consecuencia, deje de suponer un residuo problemático para el medio ambiente como lo es el de los filtros actuales. The objective of the present invention is, therefore, to provide a solution to this problem by developing a new type of filter made of a material that, while still fulfilling its protective function during the burning of tobacco for the smoker, quickly dissolves and, consequently, stop supplying a problematic waste for the environment as it is the one of the current filters.
Por otra parte, y como referencia al estado actual de la técnica, cabe señalar que, al menos por parte del solicitante, se desconoce la existencia de ningún otro filtro para tabaco, ni ninguna otra invención de aplicación similar que presente unas características técnicas y estructurales iguales o semejantes a las que presenta el que aquí se reivindica. EXPLICACIÓN DE LA INVENCIÓN On the other hand, and as a reference to the current state of the art, it should be noted that, at least on the part of the applicant, the existence of any other tobacco filter, or any other invention of similar application that has technical and structural characteristics, is unknown. equal or similar to those presented by the one claimed here.
