Description

DESCRIPCIÓN DESCRIPTION
ENVASE CILINDRICO DE CARTÓN RECICLABLE CON CIERRE INFERIOR MANUAL DE CAZOLETA Y SUS USOSRECYCLABLE CYLINDRICAL CARDBOARD PACKAGING WITH MANUAL BOTTOM CLOSURE AND ITS USES
OBJETO DE LA INVENCIÓN OBJECT OF THE INVENTION
La presente invención se refiere a un envase cilindrico de cartón reciclable con cierre inferior manual de cazoleta y su uso para contener una bolsa dispensadora de líquidos, siendo el cartón su único material constructivo del envase, por lo que dicho envase es plenamente reciclable. The present invention relates to a recyclable cylindrical cardboard container with a manual bottom cup closure and its use to contain a liquid dispensing bag, with cardboard being the only material used to construct the container, so that said container is fully recyclable.
Se conocen envases con bolsas de plástico en su interior conteniendo productos líquidos y semilíquidos, tales como vinos, licores, jarabes, aceites, leche, infusiones..., que se dispensan a través de un grifo incorporado en dicha bolsa, el cual sobresale del envase por una abertura troquelada en su franja inferior. There are known containers with plastic bags inside containing liquid and semi-liquid products, such as wines, liquors, syrups, oils, milk, infusions..., which are dispensed through a tap incorporated in said bag, which protrudes from the container through a die-cut opening in its lower strip.
Estos envases conocidos se fabrican con un tubo de cartón, y dos discos de cierre de hojalata provisto el inferior de pestaña para su fijación en el tubo. El superior se fija al tubo en fábrica del envase por medio de maquinaria especial, mientras que el inferior lo tiene que fijar el envasador después de introducir la bolsa con el líquido, por lo que dicho envasador no tiene más remedio que tener una máquina especial para fijar el disco de hojalata con pestaña que cierra el envase. La manipulación y fijación de estos discos de hojalata entraña un gran riesgo de accidentes por atrapamiento y cortes en las manos. These well-known containers are made from a cardboard tube and two tinplate sealing discs, the lower one having a tab for fixing it to the tube. The upper one is fixed to the tube in the container factory using special machinery, while the lower one has to be fixed by the packer after inserting the bag with the liquid, so the packer has no choice but to have a special machine to fix the tinplate disc with tab that closes the container. The handling and fixing of these tinplate discs entails a great risk of accidents due to entrapment and cuts to the hands.
Debido a la composición de estos envases conocidos que comprenden un tubo de cartón, dos discos de hojalata y una bolsa de plástico con grifo que sobresale al exterior de dicho envase, presentan el inconveniente de que su reciclado por el consumidor final es altamente complicado y peligroso, ya que al comprender tres materiales diferentes, cartón, plástico y hojalata, por lo general suelen terminar los tres en el contenedor de la basura orgánica. Due to the composition of these known containers, which include a cardboard tube, two tin discs and a plastic bag with a tap that protrudes from the outside of said container, they have the disadvantage that their recycling by the final consumer is highly complicated and dangerous, since, as they include three different materials, cardboard, plastic and tin, they usually all end up in the organic waste container.
Sin embargo, el envase cilindrico de cartón reciclable objeto de la presente invención consta de un tubo de cartón con las aberturas rebordeadas hacia dentro, que se cierran la superior por un disco de cartón ajustado a presión en fábrica y el inferior por una cazoleta de cartón de bordes cónicos lo suficientemente flexibles como para que una vez que la bolsa se encuentre dentro del envases, el envasador con un mínimo esfuerzo introduzca la cazoleta en el borde inferior del envase quedando la citada cazoleta aprisionada contra las pared interior del tubo However, the cylindrical recyclable cardboard container object of the present invention consists of a cardboard tube with the openings flanged inwards, the upper ones being closed by a cardboard disk fitted under pressure in the factory and the lower one by a cardboard cup with conical edges that are flexible enough so that once the bag is inside the packaging, the packer can insert the cup into the lower edge of the packaging with minimal effort, leaving the cup pressed against the inner wall of the tube.
El envasador recibe el envase con el disco de cartón fijado de fábrica en el cierre superior del tubo, después introduce en el envase la bolsa llena de líquido por la apertura inferior del tubo, y a continuación monta la cazoleta introduciéndola por la abertura inferior del tubo con los bordes cónicos hacia abajo, realizándose el encaje de dicha cazoleta con el peso de la bolsa. El tubo presenta en su franja inferior una ventana troquelada que permite su ruptura para que el usuario final, extraiga por esa ventana ya abierta el grifo dispensador. The packer receives the container with the cardboard disc factory-fixed to the upper closure of the tube, then inserts the bag filled with liquid into the container through the lower opening of the tube, and then assembles the bowl by inserting it through the lower opening of the tube with the conical edges facing downwards, the bowl being fitted with the weight of the bag. The tube has a die-cut window on its lower strip that allows it to be broken so that the end user can extract the dispensing tap through this window, once it is already open.
Las ventajas de esta invención son además de ser el envase totalmente reciclable, que el montaje de su cierre no requiere de maquinaria alguna, sino que la cazoleta se puede montar manualmente, por lo que es un envase apto tanto para pequeñas como para grandes producciones. The advantages of this invention are that, in addition to the fact that the packaging is completely recyclable, the assembly of its closure does not require any machinery, but the bowl can be assembled manually, making it a container suitable for both small and large productions.
Para mejor comprender cuanto se ha descrito el envase se entrega boca abajo, con un disco de cartón ajustado en fábrica a presión en la abertura superior del tubo. El envasador sólo tiene que introducir en el interior de éste la bolsa llena del líquido, e insertar por la apertura inferior del tubo la cazoleta con una ligera inclinación. La forma de la cazoleta le facilita la entrada en el tubo pero no su salida, ya que su forma cónica se ajusta en la parte interior del tubo y el reborde de éste le impide la salida. Una vez que el envasador coloca el envase en su posición, el peso de la bolsa del líquido hace que la cazoleta se encaje desplazándola hacia abajo, quedando ésta ajustada en la base del tubo. In order to better understand what has been described, the container is delivered upside down, with a cardboard disc fitted at the factory under pressure to the upper opening of the tube. The packer only has to place the bag filled with liquid inside the tube and insert the cup at a slight angle through the lower opening of the tube. The shape of the cup makes it easier for it to enter the tube but not to exit, since its conical shape fits into the inner part of the tube and the rim of the tube prevents it from exiting. Once the packer places the container in its position, the weight of the bag of liquid causes the cup to fit, moving it downwards, remaining adjusted to the base of the tube.
Otra ventaja de este envase es que una vez que el usuario final consume el contenido de la bolsa, dará la vuelta al conjunto del envase, y extraerá la cazoleta presionando ligeramente en un costado hacia dentro y tirando de ésta hacia fuera, y acto seguido sacará la bolsa de plástico, quedando los materiales separados para que puedan depositarse en sus correspondientes contenedores de reciclado, permitiendo finalmente el objetivo de un reciclaje responsable. Los materiales utilizados consisten en elementos estructurales plenamente reciclables fabricados novedosamente sólo a base de cartón, siendo en consecuencia un sistema original, económico y eco-responsable que adapta la geometría de la invención a los requerimientos técnicos del uso. Another advantage of this packaging is that once the end user consumes the contents of the bag, he or she will turn the entire packaging over and remove the bowl by lightly pressing inwards on one side and pulling it outwards, and then remove the plastic bag, leaving the materials separated so that they can be deposited in their corresponding recycling containers, finally allowing the objective of responsible recycling. The materials used consist of fully recyclable structural elements manufactured in a novel way only from cardboard, thus being an original, economic and eco-responsible system that adapts the geometry of the invention to the technical requirements of use.
La aplicación industrial de esta invención se encuentra dentro de los sectores de reciclaje de envases, y más concretamente, el reciclaje de envases de cartón cien por ciento reciclables. The industrial application of this invention is within the packaging recycling sector, and more specifically, the recycling of 100% recyclable cardboard packaging.
ANTECEDENTES DE LA INVENCIÓN BACKGROUND OF THE INVENTION
Aunque no se ha encontrado ninguna invención idéntica a la descrita, exponemos a continuación los documentos encontrados que reflejan el estado de la técnica relacionado con la misma. Although no invention identical to the one described has been found, we present below the documents found that reflect the state of the art related to it.
Así el documento ES2823925A1 se refiere a un procedimiento de obtención de un material reciclado a partir de envases de polietileno multicapa, los cuales son procedentes de post-consumo y/o post-industrial. Se trata, por tanto, de la obtención de un material obtenido del tratamiento de envases de PET multicapa, y no de una base estructural, como propone la invención solicitada. Thus, document ES2823925A1 refers to a process for obtaining a recycled material from multilayer polyethylene containers, which are post-consumer and/or post-industrial. It is, therefore, about obtaining a material obtained from the treatment of multilayer PET containers, and not from a structural base, as proposed by the requested invention.
El documento EP3634865A1 hace referencia a un recipiente para líquidos, que consta de al menos dos capas (11 , 12) de un material compuesto de cartón hecho de papel kraft (18) arrollado en una dirección perpendicular a su eje para obtener un cilindro hueco como cuerpo de la lata (2), en donde las juntas de conexión (15, 16) de las al menos dos capas (11 , 12) de material compuesto de cartón están en puntos desplazados con respecto a la circunferencia de los arrollamientos y un lado (6) del cilindro hueco abierto así formado está cerrado con un elemento de base (4) y el otro lado abierto (7) del cilindro hueco o el cuerpo de la lata puede cerrarse o está cerrado de la misma manera con una tapa (5) con un cierre después del envasado, caracterizado por que, para la capa más interior, los bordes se conectan a tope en la dirección de arrollamiento, mientras que la lámina más interior de la capa más interior, es decir, la lámina de barrera, se solapa con el papel kraft (18) en sus bordes en la dirección de arrollamiento, o bien las zonas de borde de la capa más interior se solapan conjuntamente en la dirección de arrollamiento, en donde en ambos casos los solapamientos, después de su doblado en ángulo recto quedan en contacto entre sí, con sus láminas de barrera alejadas de la capa arrollada (11) , se sueldan entre sí y luego se pliegan a un lado sobre la capa y se encolan a la misma, mientras que para cada capa adicional (14, 12) , las zonas de borde se solapan en la dirección de arrollamiento, en donde las zonas solapantes (45) están cortadas o rectificadas en todo su espesor oblicuamente en una superficie biselada (44) o formando un escalón (21) , de manera que las zonas solapantes quedan superpuestas en unión positiva y dichas zonas solapantes (45) no resultan más gruesas que el espesor del propio material compuesto de cartón. EP3634865A1 relates to a container for liquids, consisting of at least two layers (11, 12) of a cardboard composite material made of kraft paper (18) wound in a direction perpendicular to its axis to obtain a hollow cylinder as a can body (2), wherein the connecting joints (15, 16) of the at least two layers (11, 12) of cardboard composite material are at points offset from the circumference of the windings and one side (6) of the thus formed open hollow cylinder is closed with a base element (4) and the other open side (7) of the hollow cylinder or the can body is closable or is closed in the same way with a lid (5) with a closure after packaging, characterized in that, for the innermost layer, the edges are connected abutting in the winding direction, while the innermost sheet of the innermost layer, i.e. the barrier sheet, overlaps with the paper. Kraft (18) at its edges in the winding direction, or the edge areas of the innermost layer overlap together in the winding direction, where in both cases the overlaps, after being folded at right angles, remain in contact with each other, with their barrier sheets facing away from each other. the rolled layer (11), are welded together and then folded to one side over the layer and glued to it, while for each additional layer (14, 12), the edge regions overlap in the rolling direction, whereby the overlapping regions (45) are cut or ground over their entire thickness obliquely on a bevelled surface (44) or forming a step (21), so that the overlapping regions are superimposed in a positive fit and said overlapping regions (45) are not thicker than the thickness of the cardboard composite material itself.
ES2673488A1 propone un envase (1) aplicable al depósito y conservación de productos alimenticios, que comprende unas paredes (1a, 1b, 1c, 1d, 1e, 1f) dispuestas de manera que definen un recinto con al menos una abertura (A) para la introducción de productos alimenticios en su interior, donde al menos parte de dichas paredes (1a, 1b, 1c, 1d, 1e, 1f) permiten el paso de aire a través de la pared para airear el envase, estando el envase caracterizado porque al menos una de sus paredes (1a, 1 b, 1c, 1d, 1e, 1f) , contiene en su interior o adosado a una de sus caras, al menos un agente conservante protector frente a la humedad y apto para contacto alimentario. ES2673488A1 proposes a container (1) applicable to the storage and conservation of food products, comprising walls (1a, 1b, 1c, 1d, 1e, 1f) arranged in such a way that they define an enclosure with at least one opening (A) for the introduction of food products inside it, where at least part of said walls (1a, 1b, 1c, 1d, 1e, 1f) allow the passage of air through the wall to aerate the container, the container being characterized in that at least one of its walls (1a, 1b, 1c, 1d, 1e, 1f), contains inside or attached to one of its faces, at least one preservative agent that protects against humidity and is suitable for food contact.

DESCRIPCIÓN DE UNA REALIZACIÓN PREFERENTEDESCRIPTION OF A PREFERRED EMBODIMENT
Una realización preferente del envase cilindrico de cartón reciclable con cierre inferior manual de cazoleta y sus usos objeto de la presente invención, con alusión a las referencias numéricas, se basa en una estructura cilindrica toda de cartón reciclable para contener una bolsa dispensadora de líquidos, consistente en un tubo (1 ) cilindrico con cierre superior de disco de cartón (2) e inferior de cazoleta (3). La utilización de cartón como único material constructivo de la invención hace que dicho envase (1 ) sea plenamente reciclable. A preferred embodiment of the cylindrical recyclable cardboard container with a manual bottom cup closure and its uses, object of the present invention, with reference to the numerical references, is based on a cylindrical structure made entirely of recyclable cardboard to contain a liquid dispensing bag, consisting of a cylindrical tube (1) with an upper cardboard disk closure (2) and a lower cup closure (3). The use of cardboard as the only construction material of the invention makes said container (1) fully recyclable.
Las aberturas del tubo cilindrico (1 ) son rebordeadas (9) hacia dentro, estando cerrada la superior por un disco (2) de cartón encajado a presión en fábrica y la inferior por una cazoleta (3) de cartón de bordes cónicos lo suficientemente flexibles como para que el usuario la pueda introducir con una simple presión dejando aprisionada dicha cazoleta (3) en el reborde hacia dentro (9) inferior del tubo (2). The openings of the cylindrical tube (1) are flanged (9) inwards, the upper one being closed by a cardboard disk (2) fitted under pressure at the factory and the lower one by a cardboard cup (3) with conical edges that are flexible enough so that the user can insert it with a simple push, leaving said cup (3) trapped in the lower inward flange (9) of the tube (2).
La bolsa (5) llena de líquido es introducida por el envasador en el tubo (1 ) por su abertura inferior y la cazoleta (3) cierra la abertura inferior del tubo gracias a sus bordes cónicos hacia abajo, reforzándose el encaje de dicha cazoleta (3) con el peso de la bolsa (5). El tubo (1 ) cilindrico presenta en su franja inferior una ventana troquelada (10) que permite su ruptura para que el usuario extraiga por dicha ventana el grifo dispensador. The bag (5) filled with liquid is introduced by the packer into the tube (1) through its lower opening and the bowl (3) closes the lower opening of the tube thanks to its downward-facing conical edges, the fit of said bowl (3) being reinforced by the weight of the bag (5). The cylindrical tube (1) has a punched window (10) on its lower strip which allows it to be broken so that the user can extract the dispensing tap through said window.
El montaje de su cierre no requiere de maquinaria alguna, sino que la cazoleta (3) se monta manualmente. The assembly of the closure does not require any machinery, but the cup (3) is assembled manually.
Para mejor comprender cuanto se ha descrito el envase se entrega con el disco (2) de cierre superior de cartón ajustado en fábrica a presión. El envasador sólo tiene que introducir por su abertura inferior la bolsa (5) contenedora del líquido, y a continuación encajar sobre el reborde de esa misma abertura inferior la cazoleta (3) con una ligera inclinación. La forma de la cazoleta (3) facilita la entrada de ésta en el tubo (1 ) cilindrico pero no su salida, ya que la forma cónica de su borde se ajusta sobre el reborde interior del tubo (1 ) que le impide su salida. Una vez que el envase se encuentra en su posición vertical, el peso de la bolsa (5) contenedora del líquido hace que la cazoleta (3) se termine de encajar desplazándose hacia abajo, quedando así plenamente ajustada en la base del tubo (1 ). In order to better understand what has been described, the container is delivered with the upper cardboard closing disk (2) fitted at the factory under pressure. The packer only has to insert the bag (5) containing the liquid through its lower opening, and then fit the bowl (3) onto the rim of that same lower opening at a slight angle. The shape of the bowl (3) facilitates its entry into the cylindrical tube (1 ) but not its exit, since the conical shape of its edge fits over the inner rim of the tube (1 ) which prevents its exit. Once the container is in its vertical position, the weight of the bag (5) containing the liquid makes it easier to insert the liquid into the tube (1 ). that the bowl (3) finishes fitting by moving downwards, thus remaining fully adjusted in the base of the tube (1).
Una vez que el usuario final consume el contenido de la bolsa (5), dando la vuelta al envase extrae la cazoleta (3) presionando ligeramente en el costado de ésta hacia dentro y tirando de la misma hacia fuera, y acto seguido saca la bolsa (5) de plástico, quedando los materiales separados para que puedan depositarse en sus respectivos contenedores de reciclado, permitiendo así el objetivo de un reciclaje responsable.Once the end user consumes the contents of the bag (5), turning the container upside down, he/she removes the bowl (3), pressing lightly on the side of it inwards and pulling it outwards, and then removes the plastic bag (5), leaving the materials separated so that they can be deposited in their respective recycling containers, thus allowing the objective of responsible recycling.
Los materiales utilizados para el envase consisten en elementos estructurales plenamente reciclables fabricados novedosamente sólo a base de cartón, siendo en consecuencia un envase original, económico y eco-responsable que adapta su geometría a los requerimientos técnicos del uso. The materials used for the packaging consist of fully recyclable structural elements manufactured in a novel way only from cardboard, resulting in an original, economical and eco-responsible packaging that adapts its geometry to the technical requirements of use.
