ANTECEDENTES DE LA INVENCIÓNBACKGROUND OF THE INVENTION

En vista al amplio mercado que existe de envases y dispensadores, es de entender que sus proveedores intenten distinguirse de la competencia mediante productos más atractivos para el consumidor y a un coste menor.In view of the wide market that exists of containers and dispensers, it is to be understood that their suppliers try to distinguish themselves from the competition through more attractive products for the consumer and at a lower cost.

Uno de los aspectos clave en la distinción de los envases, sobre todo en el sector de la perfumería, la cosmética y las bebidas espirituosas, son sus tapones. Son conocidos diferentes procedimientos de fabricación de tapones, con diseños y costes de fabricación totalmente dispares entre unos y otros.One of the key aspects in the distinction of packaging, especially in the sector of perfumery, cosmetics and spirits, are their caps. Different methods of manufacturing caps are known, with totally different designs and manufacturing costs between them.

Es por tanto objetivo de cualquier proveedor de tapones de desarrollar procesos de fabricación con costes reducidos, que a la vez proporcionen tapones con un aspecto distinguido respecto al de la competencia. La presente invención contribuye a aportar varias alternativas de procesos de fabricación de tapones con dichos requerimientos.It is therefore the objective of any cap supplier to develop manufacturing processes with reduced costs, which at the same time provide caps with a distinguished appearance compared to the competition. The present invention contributes to provide several alternatives of manufacturing processes of caps with said requirements.

DESCRIPCIÓN DE LA INVENCIÓNDESCRIPTION OF THE INVENTION

La presente invención proporciona un procedimiento de fabricación que permite la obtención de tapones que comprenden una decoración tridimensional, con la ventaja de que es personalizable para cada cliente a unos costes reducidos, el cual se basa en realizar una o varias etapas de decoración de la materia prima de los tapones previamente a su individualización.The present invention provides a manufacturing process that allows obtaining caps that comprise a three-dimensional decoration, with the advantage that it is customizable for each client at reduced costs, which is based on making one or more several stages of decoration of the raw material of the plugs prior to their individualization.

El procedimiento de fabricación parte de una o varias barras macizas como materia prima, preferiblemente de madera, a las cuales se les aplica un proceso de decoración en toda la longitud de al menos una de sus superficies. Estas barras decoradas pasan a cortarse en trozos, los cuales acabaran formando el cuerpo de los tapones.The manufacturing process starts from one or several solid bars as raw material, preferably of wood, to which a decoration process is applied over the entire length of at least one of its surfaces. These decorated bars are cut into pieces, which will eventually form the body of the plugs.

Dicha materia prima puede estar constituida por una única barra maciza, a cuyo contorno entero se le aplica un proceso de decoración, sea cual sea la forma del contorno. En caso de ser circular, el proceso de decoración del contorno se puede dividir en tantos ciclos de decoración longitudinal como se desee. En caso de que el contorno comprenda más de una cara, el proceso de decoración se puede realizar en cada una o en varias de las caras longitudinales a la vez.Said raw material can be constituted by a single solid bar, to whose entire contour a decoration process is applied, whatever the shape of the contour. If it is circular, the contour decoration process can be divided into as many longitudinal decoration cycles as desired. In case the contour includes more than one face, the decoration process can be carried out on each or several of the longitudinal faces at the same time.

Por otro lado, dicha materia prima puede estar constituida por más de una barra, a las cuales se les puede aplicar el proceso de decoración en alguna de sus caras longitudinales y después unirlas de forma que se muestren las caras decoradas.On the other hand, said raw material can be constituted by more than one bar, to which the decoration process can be applied to any of its longitudinal faces and then joined so that the decorated faces are shown.

Según el objeto de la presente invención, el procedimiento de fabricación de los tapones comprende al menos las siguientes etapas:According to the object of the present invention, the method of manufacturing the caps comprises at least the following steps:

- provisión de una o más barras macizas, donde dichas barras comprenden una o más superficies longitudinales configuradas para ser decoradas,- provision of one or more solid bars, where said bars comprise one or more longitudinal surfaces configured to be decorated,

- aplicación de un proceso de decoración en al menos una de dichas superficies de las barras,- application of a decoration process on at least one of said bar surfaces,

- corte de dichas barras por una longitud predefinida para generar cuerpos de tapón, y - cutting said bars by a predefined length to generate plug bodies, and

- aplicación de un proceso de generación de medios de acople en los cuerpos de tapón, dichos medios estando configurados para acoplar dichos cuerpos de tapón de manera segura en el cuello de un envase.- application of a process for generating coupling means in the stopper bodies, said means being configured to engage said stopper bodies securely in the neck of a container.

Respecto a la etapa de aplicación de un proceso de decoración, una posible opción es la de aplicar una pasta de relieve en la superficie configurada para ser decorada, y a continuación aplicarle presión con unos medios de moldeo a dicha superficie cubierta con la pasta de relieve, de forma que los motivos contenidos en el molde se transfieren a la pasta de relieve. Regarding the stage of application of a decoration process, a possible option is to apply a relief paste on the surface configured to be decorated, and then apply pressure with molding means to said surface covered with the relief paste, so that the motifs contained in the mold are transferred to the relief paste.

Otro posible proceso de decoración de las superficies longitudinales de las barras consiste en aplicar directamente sobre la superficie de la barra una presión en caliente con unos medios de moldeo convenientes para ello. En este caso, las barras deberían ser preferiblemente de madera blanda. A su vez, existiría la posibilidad de proporcionar una lámina de color o una película de material colorante en la superficie de la barra, ya sea antes de aplicar la presión en caliente, de forma que al aplicar esta, quedaría transferida tanto la película de color como los motivos del molde, o bien después de aplicar la presión en caliente en un proceso adicional.Another possible process for decorating the longitudinal surfaces of the bars is to apply a hot pressure directly on the surface of the bar with suitable molding means. In this case, the bars should preferably be soft wood. In turn, there would be the possibility of providing a color sheet or a film of coloring material on the surface of the bar, either before applying the hot pressure, so that when applying this, both the color film would be transferred as the mold motifs, or after applying the hot pressure in an additional process.

En cualquiera de las opciones de procesos de decoración anteriores, los medios de moldeo pueden ser cualquiera de los existentes en el mercado, como por ejemplo lo podrían ser un rodillo rotativo previsto con una superficie con relieves o una plancha de prensado prevista con una superficie con relieves.In any of the above decoration process options, the molding means can be any of those existing on the market, such as a rotating roller provided with a surface with reliefs or a pressing plate provided with a surface with reliefs

Por otro lado, cualquiera de las opciones de procesos de decoración anteriores también podría comprender una etapa adicional de aplicación de pintura, de estampación, de serigrafía o similares, mediante los cuales es posible añadir elementos decorativos tales como textos o imágenes en al menos una de las superficies de la barra.On the other hand, any of the above decoration process options could also comprise an additional stage of applying paint, stamping, screen printing or the like, by means of which it is possible to add decorative elements such as texts or images in at least one of The surfaces of the bar.

Respecto a la etapa de generación de los medios de acople, una posible opción sería generar un agujero roscado en una superficie del cuerpo de tapón, estando dicho agujero roscado configurado para acoplarse a un extremo roscado de un contenedor. Otra opción sería generar un agujero ciego en una superficie del cuerpo de tapón e insertar un casquillo en dicho agujero, estando dicho casquillo configurado para acoplarse a un contenedor, sea por rosca o por presión. Dicho casquillo puede quedar fijado al tapón a través de medios ya conocidos, como puede ser mediante encolado, mediante pestañas preexistentes que se deforman al introducir el casquillo, mediante el punzonado del casquillo para la generación de resaltes que queden agarrados al cuerpo del tapón o mediante un proceso de encliquetado, por el cual un saliente de fijación se encuentra dispuesto en el agujero del tapón y el casquillo cuenta con una ranura o similar, de una geometría elásticamente deformable, tal que mediante un forzamiento adecuado se produce el acoplamiento entre el saliente y la ranura de forma perenne.With respect to the step of generating the coupling means, a possible option would be to generate a threaded hole in a surface of the plug body, said threaded hole being configured to engage a threaded end of a container. Another option would be to generate a blind hole in a surface of the cap body and insert a bushing into said hole, said bushing being configured to engage a container, either by thread or by pressure. Said bushing can be fixed to the plug through known means, such as by gluing, by means of pre-existing tabs that deform when the bushing is inserted, by punching the bushing for the generation of projections that remain attached to the body of the plug or by an enclosure process, whereby a fixing projection is arranged in the hole of the plug and the bushing has a groove or the like, of an elastically deformable geometry, such that by coupling the coupling between the projection and the perennial groove.

Indistintamente de las opciones anteriores, el procedimiento de fabricación también puede comprender una etapa suplementaria de decoración de los tapones de forma individualizada en cualquiera de las superficies de los cuerpos de tapón. Regardless of the above options, the manufacturing process can also comprise a supplementary stage for decorating the caps individually on any of the surfaces of the plug bodies.

En relación al procedimiento aquí descrito y a sus variantes, se dan por incluidos los procesos de secado que puedan necesitar cualquiera de las etapas, procesos o materiales anteriormente descritos.In relation to the procedure described herein and its variants, drying processes that may require any of the steps, processes or materials described above are included.

Gracias al presente procedimiento, se consigue la fabricación en masa de tapones que ya comprenden los contornos decorados, con dos superficies planas una superior y otra inferior, paralelas o no, donde la superficie superior y el contorno de los tapones pueden recibir un tratamiento adicional de mecanizado y/o decoración, y conteniendo la superficie inferior un orificio cuyo contorno interior está habilitado para, o bien ser insertado y retenido en el cuello de un envase o bien para la recepción de un elemento de retención al cuello de un envase. Thanks to the present process, the mass production of plugs that already comprise the decorated contours is achieved, with two flat surfaces one upper and one lower, parallel or not, where the upper surface and the contour of the plugs can receive an additional treatment of machining and / or decoration, and the bottom surface containing a hole whose inner contour is enabled to either be inserted and retained in the neck of a container or to receive a retention element to the neck of a container.
