Description
DESCRIPCIÓNDESCRIPTION
Un recipiente resellable A resealable container
Campo de la invenciónfield of invention
La presente invención se refiere a recipientes, en particular a recipientes para productos domésticos. The present invention relates to containers, in particular containers for household products.
La invención fue desarrollada en particular con vistas a su aplicación a recipientes para su aplicación a detergentes para colada y lavavajilla, en particular a cápsulas detergentes. The invention was developed in particular with a view to its application to containers for application to laundry and dishwashing detergents, in particular to detergent capsules.
Técnica anteriorPrevious technique
Hoy día, los recipientes resellables para productos domésticos son casi enteramente fabricados a partir de plásticos (mono o poli acoplados, flexibles o rígidos), que son fabricados a partir de recursos fósiles y, en consecuencia, presentan un impacto energético y medioambiental considerable tanto respecto a su producción como a su reciclado. El impacto energético y medioambiental no se reduce incluso cuando se utilizan plásticos reciclables. Today, resealable containers for household products are almost entirely manufactured from plastics (mono- or poly-coupled, flexible or rigid), which are manufactured from fossil resources and, consequently, have a considerable energy and environmental impact both with respect to to its production and recycling. The energy and environmental impact is not reduced even when recyclable plastics are used.
Por tanto, existe una urgente necesidad de unos recipientes para productos domésticos que sean reciclables en la cadena de papel. Therefore, there is an urgent need for containers for household products that are recyclable in the paper chain.
Sin embargo, los recipientes fabricados a partir de materiales de papel presentan limitaciones relativas a los cierres resellables. De hecho, los materiales de papel, ya se trate de pulpa de celulosa, papel, o cartón, no presentan la misma elasticidad que los plásticos, y los cierres resellables fabricados a partir de estos materiales no pueden conseguir las mismas funciones que las conseguidas utilizando material plástico. En particular, las operaciones de apertura y cierre tienden a doblar y desgastar los elementos de cierre, los cuales, después de un corto periodo de tiempo, ya no son capaces de asegurar un cierre eficaz. However, containers made from paper materials have limitations regarding resealable closures. In fact, paper materials, whether cellulose pulp, paper, or cardboard, do not have the same elasticity as plastics, and resealable closures manufactured from these materials cannot achieve the same functions as those achieved using plastic material. In particular, opening and closing operations tend to bend and wear the closing elements, which, after a short period of time, are no longer capable of ensuring effective closing.
Así mismo, si los recipientes están enteramente fabricados a partir de material de papel es difícil asegurar su conformidad con los estándares a prueba de niños, tales como el estándar UNI EN ISO 8317:2005 "Embalaje a prueba de niños - Requisitos y procedimientos de ensayo para embalajes resellables". Likewise, if containers are made entirely from paper material it is difficult to ensure their compliance with child-resistant standards, such as the UNI EN ISO 8317:2005 standard "Child-resistant packaging - Requirements and test procedures for resealable packaging".
Son conocidas las soluciones de plástico ecocompatible. Por ejemplo, el documento WO 2016/207849 divulga una composición termoplástica hecha de celulosa y de un polímero polihidroxilado hidrolizable o hidrosoluble que es soluble en agua. Eco-friendly plastic solutions are known. For example, WO 2016/207849 discloses a thermoplastic composition made of cellulose and a hydrolyzable or water-soluble polyhydroxylated polymer that is soluble in water.
Un recipiente fabricado a partir de este material sería reciclable a partir de este papel en cuanto se disolvería en agua y el residuo después de la disolución estaría compuesto por celulosa. A container made from this material would be recyclable from this paper as it would dissolve in water and the residue after dissolution would be composed of cellulose.
Sin embargo, los materiales plásticos solubles en agua no son adecuados para fabricar recipientes para productos domésticos, como por ejemplo, cápsulas de detergentes, polvos de detergentes y similares. De hecho, los recipientes de productos domésticos a menudo están almacenados en compartimentos de cocinas y de cuartos de baño y quedan a menudo expuestos a la humedad y al agua, lo que rápidamente deterioraría los recipientes. Así mismo, el usuario puede sujetar dichos recipientes con las manos húmedas, lo que dejaría residuos pegajosos en las manos del usuario y deterioraría las partes de los recipientes que han estado en contacto con el agua. However, water-soluble plastic materials are not suitable for making containers for household products, such as detergent capsules, detergent powders and the like. In fact, containers for household products are often stored in kitchen and bathroom compartments and are often exposed to humidity and water, which would quickly deteriorate the containers. Likewise, the user may hold said containers with wet hands, which would leave sticky residue on the user's hands and deteriorate the parts of the containers that have been in contact with the water.
Así mismo, los materiales plásticos solubles en agua presentan una apariencia de tipo plástico, la cual puede confundir al usuario acerca de la forma de otorgar el tratamiento correcto a la recogida de los desechos de reciclado. De hecho, los recipientes fabricados con materiales plásticos solubles en agua deben ser desechados en la cadena de plástico en cuanto contaminarían la cadena de reciclado de plástico frente a una primera e inmediata evaluación que podría conducir al usuario a su desecho como plástico. Likewise, water-soluble plastic materials have a plastic-like appearance, which can confuse the user about how to provide the correct treatment when collecting recycling waste. In fact, containers made with water-soluble plastic materials must be discarded in the plastic chain as they would contaminate the plastic recycling chain in the face of a first and immediate evaluation that could lead the user to discard them as plastic.
Así mismo, los materiales plásticos solubles en agua son costosos e incrementarían considerablemente los costes de envasado en comparación con los costes de los envases de papel. El documento WO 2021/183629 A, que constituye la técnica anterior en los términos del apartado (3) del Artículo 54 del EPC, divulga una bolsa con cremallera repulpable, en la que los perfiles de la cremallera están compuestos por un material soluble en agua. Likewise, water-soluble plastic materials are expensive and would considerably increase packaging costs compared to the costs of paper packaging. Document WO 2021/183629 A, which constitutes the prior art in terms of paragraph (3) of Article 54 of the EPC, discloses a repulpable zipper bag, in which the zipper profiles are composed of a water-soluble material .
El documento WO 9411257 A1 divulga un recipiente de acuerdo con el preámbulo de la presente reivindicación 1, que incluye un cuerpo de recipiente y una cubierta móvil hecha de cartón, y un medio de pestillo compuesto por una pieza unitaria de polímero resistente al rasgado, como por ejemplo, polietileno reciclado. WO 9411257 A1 discloses a container according to the preamble of the present claim 1, including a container body and a movable cover made of cardboard, and a latch means composed of a unitary piece of tear-resistant polymer, such as for example, recycled polyethylene.
Objetivo y sumario de la invenciónObjective and summary of the invention
Un objetivo de la presente invención es proporcionar un recipiente ecosostenible para productos domésticos que solvente los problemas de la técnica anterior.
