Molde de inyección para moldeo de un envase de material plástico y envase obtenido.Injection mold for molding a container plastic material and container obtained.
La presente solicitud de Patente de Invención tiene por objeto un molde adaptado para moldeo por inyección de un envase de material plástico, concebido para permitir un dilatado tiempo de operación con mínimas operaciones de mantenimiento.The present invention patent application It aims at a mold adapted for injection molding of a plastic container, designed to allow dilated operating time with minimal maintenance operations.
Más concretamente, la invención hace referencia a un molde para moldeo por inyección de un envase de material plástico, el cual comprende un cuerpo de recipiente y una tapa hueca, abatible, interconectados entre sí a través de una bisagra que no abarca por completo la arista del cuerpo del envase de articulación, dejando dos porciones extremas libres. Dicho cuerpo de recipiente, tapa y bisagra son integralmente obtenidos por moldeo, y la bisagra es sensiblemente estrecha pudiendo disponerse la citada tapa adosada y quedando muy próxima a una pared exterior, trasera, del envase, en situación de apertura, liberando por completo la boca de dicho cuerpo de recipiente.More specifically, the invention makes reference to a mold for injection molding of a container of material plastic, which comprises a container body and a lid hollow, foldable, interconnected with each other through a hinge which does not fully cover the edge of the container body of joint, leaving two free end portions. Said body of container, lid and hinge are integrally obtained by molding, and the hinge is noticeably narrow and the aforementioned can be arranged lid attached and being very close to an exterior, rear wall, of the container, in an opening situation, completely freeing the mouth of said container body.
El molde de inyección propuesto está formado por un bloque metálico provisto de una primera cavidad para la conformación del cuerpo de recipiente y una segunda cavidad para la conformación de la tapa adyacente quedando separadas las embocaduras de las dos cámaras por un tabique intermedio, delgado. Dado que la bisagra no abarca toda la longitud de la arista de articulación del envase, dejando en los dos extremos unas zonas libres, ello determina que el citado tabique se extiende en voladizo entre las citadas embocaduras y debe proporcionar unas condiciones de rigidez estructural que garanticen la operativa del molde.The proposed injection mold is formed by a metal block provided with a first cavity for the conformation of the container body and a second cavity for the conformation of the adjacent cover leaving the openings separated of the two chambers by an intermediate, thin partition. Given that the hinge does not cover the entire length of the articulation edge of the container, leaving free zones at both ends, it determines that said partition is cantilevered between the cited mouthpieces and must provide stiffness conditions structural that guarantee the operation of the mold.
En el mercado existen una amplia variedad de envases de plástico, por ejemplo, aquellos formados por un cuerpo recipiente y una tapa superior hueca, destinados a conservar una sustancia líquida o sólida de forma encapsulada (tal como un producto farmacéutico), por ejemplo, en sobres.In the market there is a wide variety of plastic containers, for example, those formed by a body container and a hollow top lid, intended to preserve a liquid or solid substance in encapsulated form (such as a pharmaceutical product), for example, in sachets.
Son asimismo conocidos envases del tipo
indicado, comprendiendo un cuerpo recipiente y una tapa hueca, en
donde ambos están unidos por medio de una bisagra flexible producida
en el mismo instante en que se lleva a cabo la configuración por
moldeo de los dos cuerpos por ejemplo obtenidos integralmente
mediante un molde de inyección. Pueden citarse, únicamente a título
de Ejemplo el modelo de utilidad
ES-A-1038812 (ver Fig. 1) y la
patente US 4 759 478.Containers of the indicated type are also known, comprising a container body and a hollow lid, where both are joined by means of a flexible hinge produced at the same moment in which the configuration by molding of the two bodies obtained for example obtained is carried out. integrally through an injection mold. The utility model can be cited only as an example
ES-A-1038812 (see Fig. 1) and US 4 759 478.
Para la obtención de un tal envase, el molde suele estar configurado de tal modo que existen dos cavidades adyacentes destinadas a conformar el cuerpo recipiente y la tapa hueca y una porción intermedia a modo de tabique, que una vez el molde está cerrado, define una estrecha comunicación entre las dos cavidades que proporciona la bisagra que une el cuerpo recipiente y la tapa.To obtain such a container, the mold it is usually configured in such a way that there are two cavities adjacent to form the container body and the lid hollow and an intermediate portion as a partition, which once the mold is closed, defines a close communication between the two cavities provided by the hinge that joins the container body and the lid
Si, como ocurre con el presente envase, dicha bisagra es estrecha, es decir la tapa cuando está alzada y abatida contra la pared exterior del cuerpo del envase, queda muy próxima a dicha pared, ello implica que el citado tabique es delgado y dicho tabique constituye un elemento en voladizo que debe resistir la presión de inyección, elevada necesaria por otro lado si se quiere conseguir una consistencia y rigidez adecuada de la pared del envase.Yes, as with the present package, said hinge is narrow, that is the lid when it is raised and dejected against the outer wall of the container body, it is very close to said wall, this implies that said partition is thin and said septum constitutes a cantilever element that must resist the injection pressure, high required on the other hand if desired achieve adequate consistency and stiffness of the wall of the container.
En la práctica se ha observado que dicho tabique intermedio que se extiende entre las dos embocaduras del molde adoptando una configuración a modo de "una viga en voladizo" tiende a romperse al cabo de un número determinado de ciclos debido a los esfuerzos por fatiga que debe soportar dicha porción en cada ciclo de inyectado, teniendo en cuenta además la presión de inyección elevada y el mantenimiento de tal presión durante un período de tiempo relativamente elevado que aceleran la fatiga de dicho tramo.In practice it has been observed that said partition intermediate extending between the two mouths of the mold adopting a configuration like "a cantilever beam" tends to break after a certain number of cycles because to the fatigue efforts that such portion must withstand in each injected cycle, also taking into account the pressure of high injection and maintenance of such pressure during a relatively high period of time that accelerate the fatigue of said stretch.
La rotura se inicia en un extremo de la bisagra y finaliza en el otro extremo adoptando una forma curva y alcanzando un máximo en una zona donde finaliza la parte delgada del citado tabique o entrehierro que queda entre cuerpo y tapa.Breaking begins at one end of the hinge and ends at the other end adopting a curved shape and reaching a maximum in an area where the thin part of the aforementioned ends partition or air gap between body and lid.
Para resolver este problema se conoce el recurso al uso de materiales termoplásticos distintos con propiedades de fluidez diferentes o bien la modificación de parámetros de fabricación, tales como la presión de la inyección.To solve this problem the resource is known to the use of different thermoplastic materials with properties of different fluency or the modification of parameters of manufacturing, such as injection pressure.
Sin embargo tales alternativas no proporcionan en general una solución suficiente que permita ofrecer una medida de la boca del envase y un peso del mismo con una estrecha tolerancia además de una fuerza de cierre y de apertura de la tapa determinadas, adecuada a los requisitos solicitados. Así, por Ej. el uso de un material plástico de mayor fluidez implica un aumento en la rigidez del material y en consecuencia el envase obtenido resulta más frágil y, por lo tanto, quebradizo con las consecuencias negativas que tiene en el proceso de llenado del citado envase.However such alternatives do not provide in general a sufficient solution that allows to offer a measure of the mouth of the container and its weight with a narrow tolerance in addition to a closing and opening force of the lid determined, appropriate to the requested requirements. Thus, for example the use of a more fluid plastic material implies an increase in the rigidity of the material and consequently the package obtained results more fragile and therefore brittle with the consequences negative that you have in the process of filling the aforementioned container.
La presente invención se ha desarrollado con el fin de proporcionar un molde de inyección que resuelva los inconvenientes anteriormente mencionados, aportando, además, otras ventajas adicionales que serán evidentes a partir de la descripción que se acompaña a continuación.The present invention has been developed with the in order to provide an injection mold that solves the drawbacks mentioned above, also providing other additional advantages that will be apparent from the description which is accompanied below.
Es por lo tanto un objeto de la presente invención proporcionar un molde adaptado para moldeo por inyección de un envase de material plástico que comprende un cuerpo de recipiente y una tapa hueca, interconectados entre sí a través de una bisagra solidaria a ambas partes del envase, es decir, todo el envase está obtenido por moldeo de una sola pieza, siendo la bisagra estrecha y quedando dicha tapa, en situación de máxima abertura muy próxima a una pared lateral exterior del envase. Además la bisagra no abarca toda la arista de articulación al envase, dejando unas porciones extremas libres.It is therefore an object of the present invention provide a mold adapted for injection molding of a plastic container comprising a body of container and a hollow lid, interconnected with each other through a hinge integral to both parts of the package, that is, all the container is obtained by molding one piece, being the hinge narrow and remaining said lid, in a situation of maximum opening very next to an outer side wall of the container. Also the hinge does not cover the entire articulation edge to the container, leaving some Extreme free portions.
El recipiente a obtener ha de tener una rigidez estructural suficiente para evitar que el contenido pueda resultar dañado y una configuración de la boca del envase y de unos elementos de cierre asociados a tapa y envase que garantice una seguridad y una apertura con una fuerza dada.The container to be obtained must have a rigidity structural enough to prevent the content may result damaged and a configuration of the mouth of the container and some elements of closing associated to cover and container that guarantees a security and an opening with a given force.
El molde de inyección que se propone está formado por un cuerpo metálico provisto de una primera cavidad para la conformación del cuerpo de recipiente y una segunda cavidad para la conformación de la tapa hueca adyacente y separada de la primera mediante una porción intermedia a modo de listón de separación que se extiende entre las dos cavidades a las que comunica por su arista libre superior cuando el molde está cerrado.The injection mold proposed is formed by a metal body provided with a first cavity for the conformation of the container body and a second cavity for the conformation of the adjacent hollow lid and separated from the first by means of an intermediate portion as a slat that it extends between the two cavities to which it communicates by its edge Top free when the mold is closed.
El molde propuesto se caracteriza por el hecho de que dicha porción o tabique intermedio de separación, en voladizo, presenta al menos un tramo con una sección transversal que se ensancha desde la parte superior hasta la parte inferior o nacimiento, donde confluye en la superficie de fondo de la segunda cavidad. Dicha confluencia tiene lugar además a través de un diedro curvo-cóncavo.The proposed mold is characterized by the fact that said portion or intermediate partition, in cantilever, it has at least one section with a cross section that widens from the top to the bottom or birth, where it converges on the background surface of the second cavity. This confluence also takes place through a dihedral curved-concave.
Según una realización preferida de la invención dicho tabique intermedio comprende una porción central de ligera menor altura, dando lugar a dos tiras de bisagra franqueadas por una hendidura central en el envase formado. En cualquier caso dichas dos bisagras no alcanzan los extremos de la arista de articulación del envase.According to a preferred embodiment of the invention said intermediate partition comprises a central portion of light lower height, resulting in two strips of hinge franked by one central groove in the formed container. In any case these two hinges do not reach the ends of the articulation edge of the container.
De acuerdo con otro aspecto de la invención dicho tabique intermedio presenta unas porciones de menor altura en dos tramos de igual longitud junto a sus extremos, de manera que la bisagra obtenida queda limitada a un sector central que enlaza cuerpo y tapa hueca.In accordance with another aspect of the invention said intermediate partition has smaller portions in two sections of equal length next to its ends, so that the hinge obtained is limited to a central sector that links hollow body and lid.
Según otro aspecto del molde de la invención, la zona cercana a los extremos de la porción intermedia del molde presenta una sección transversal progresiva.According to another aspect of the mold of the invention, the area near the ends of the intermediate portion of the mold It presents a progressive cross section.
De forma ventajosa, el ensanchamiento de la porción intermedia es gradual a lo largo del desarrollo en altura de la misma, y proporciona una sección transversal del citado listón intermedio, aproximadamente en forma de triángulo rectángulo, con la superficie inclinada orientada hacia la cavidad formadora de la tapa.Advantageously, the widening of the intermediate portion is gradual along the height development of the same, and provides a cross section of said ribbon intermediate, approximately in the form of a right triangle, with the inclined surface facing the forming cavity of the top.
Es otro objeto de la invención proporcionar un envase de material plástico que comprende un cuerpo de recipiente y una tapa sensiblemente interiormente hueca interconectados entre sí a través de una bisagra solidaria a ambas partes del envase obtenido mediante el molde anteriormente expuesto.It is another object of the invention to provide a plastic container comprising a container body and a substantially internally hollow lid interconnected with each other through a hinge integral to both parts of the container obtained by the mold set forth above.
En este envase, la tapa presenta una de las paredes laterales mayor inclinada con respecto al eje transversal de la tapa. Dicha pared inclinada es la que queda adosada contra la trasera del envase cuando este es abierto. La citada pared inclinada termina en una arista en canto romo correspondiente a la superficie superior de la tapa, en situación operativa de cierre.In this container, the lid has one of the side walls greater inclined with respect to the transverse axis of the lid Said inclined wall is the one that is leaned against the Rear of the container when it is opened. The said inclined wall ends in a blunt edge corresponding to the surface upper cover, in operative closing situation.
En una realización preferida, el tramo con la sección transversal que se ensancha desde la parte superior hasta la parte inferior tiene una longitud equivalente a la bisagra del cuerpo del envase. Cabe mencionar que la bisagra puede ser de tipo continua o discontinua, es decir, disponer de dos o más tramos de bisagra.In a preferred embodiment, the section with the cross section that widens from the top to the bottom has a length equivalent to the hinge of the container body It should be mentioned that the hinge can be of type continuous or discontinuous, that is, have two or more sections of hinge.
Gracias a las características del molde de inyección aquí expuesto, se incrementa considerablemente la rigidez de la porción intermedia del molde de tal manera que se evita su rotura no deseada, y como resultado se mejora la productividad en la fabricación del envase a obtener y se consigue una reducción en los costes de mantenimiento para las operaciones de extracción y reparación del molde. Esta característica afecta mínimamente el diseño de la pieza obtenida con el molde tradicional, puesto que la citada pared inclinada apenas afecta a la capacidad del envase.Thanks to the mold features of injection exposed here, stiffness is greatly increased of the intermediate portion of the mold in such a way that its unwanted breakage, and as a result productivity in the manufacture of the package to be obtained and a reduction in the maintenance costs for extraction operations and mold repair. This feature minimally affects the design of the piece obtained with the traditional mold, since the said inclined wall hardly affects the capacity of the container.
Además, el envase obtenido por medio del procedimiento descrito anteriormente presenta unas características que se adecuan eficazmente a las exigencias requeridas en lo que se refiere a un funcionamiento correcto de la bisagra, un peso y tolerancias adecuado, la fuerza de cierre de la tapa y un aspecto superficial y rebabas.In addition, the container obtained by means of The procedure described above has some characteristics that are effectively adapted to the requirements required in what is refers to the proper functioning of the hinge, a weight and Adequate tolerances, the closing force of the lid and an appearance superficial and burrs.
Otras características y ventajas del molde inyección objeto de la presente invención resultarán evidentes a partir de la descripción de una realización preferida, pero no exclusiva, que se ilustra a modo de ejemplo no limitativo en los dibujos que se acompañan, en los cuales.Other features and advantages of the mold Injection object of the present invention will be apparent to from the description of a preferred embodiment, but not exclusive, which is illustrated by way of non-limiting example in the accompanying drawings, in which.

De acuerdo con las figuras esmentadas, una realización del molde de inyección de la invención destinado a ser montado en una máquina de inyección de tipo convencional (no representada en la invención ya que no forma parte de la invención) comprende un cuerpo metálico 10 hecho de metal conocido el cual está provisto de una primera cavidad 11 para la conformación de un cuerpo de recipiente del envase a fabricar, que se describirá más adelante, y una segunda cavidad 12 correspondiente a la conformación de la tapa adyacente del envase, estando ambas cavidades 11 y 12 separadas por medio de un tabique intermedio de separación 13 que forma parte del propio cuerpo metálico 10.According to the structured figures, a embodiment of the injection mold of the invention intended to be mounted on a conventional type injection machine (no represented in the invention since it is not part of the invention) it comprises a metallic body 10 made of known metal which is provided with a first cavity 11 for the conformation of a body container container to be manufactured, which will be described later, and a second cavity 12 corresponding to the conformation of the adjacent container lid, both cavities 11 and 12 being separated by means of an intermediate partition 13 that forms part of the metal body itself 10.
Dicho tabique de separación 13 presenta un tramo con una sección transversal que se ensancha desde su arista superior hasta la parte inferior en donde confluye con el fondo de la segunda cavidad 12 del molde, siendo el ensanchamiento gradual a lo largo del desarrollo en altura del mismo, en forma de una superficie inclinada, tal puede verse con mayor claridad en la figura 3. De esta manera, se aporta una mayor rigidez al conjunto del molde de inyección evitando así la posible rotura del mismo que conllevaría inconvenientes destacables durante el proceso de fabricación de un envase en un proceso industrial continuo. En el ejemplo mostrado la sección transversal que se ensancha tiene una longitud equivalente a la longitud de la bisagra del envase.Said separation partition 13 has a section with a cross section that widens from its upper edge to the bottom where it meets the bottom of the second cavity 12 of the mold, the gradual widening being along of its height development, in the form of a surface inclined, as can be seen more clearly in Figure 3. From in this way, greater rigidity is provided to the mold assembly of injection thus avoiding possible breakage that would lead to notable inconveniences during the manufacturing process of a container in a continuous industrial process. In the example shown the cross section that widens has a length equivalent to the length of the hinge of the container.
Como se aprecia en la figura 4, se muestra un envase de material plástico con un espesor de material de aproximadamente 3 mm., indicado de forma general con la referencia 20, obtenido por medio del molde de inyección anteriormente descrito que comprende esencialmente un cuerpo de recipiente 21 y una tapa sensiblemente interiormente hueca 22, cuya tapa 22 presenta una altura menor con respecto al cuerpo recipiente 21 que están interconectados entre sí a través de una bisagra 23 solidaria con ambas partes 21 y 22, cuya bisagra 23 está dispuesta en la parte posterior del envase. Como puede verse con mayor claridad, la tapa 22 presenta en una de las paredes laterales mayores una inclinación 24 con respecto al eje transversal de la tapa 22. El material plástico empleado puede ser cualquiera de los habitualmente empleados en la fabricación de envases, tal como por ejemplo polipropileno.As seen in Figure 4, a plastic container with a material thickness of approximately 3 mm., indicated generally with the reference 20, obtained by means of the injection mold described above essentially comprising a container body 21 and a lid substantially internally hollow 22, whose lid 22 has a smaller height with respect to the container body 21 that are interconnected with each other through a hinge 23 integral with both parts 21 and 22, whose hinge 23 is arranged in the part back of the container As you can see more clearly, the lid 22 has an inclination on one of the major side walls 24 with respect to the transverse axis of the lid 22. The material plastic used can be any of the usual used in the manufacture of packaging, such as Polypropylene.
En el ejemplo aquí mostrado la bisagra 23 presenta un recorrido continuo si bien será evidente para cualquier experto en la materia que en vez de una sola bisagra continua, pueden estar formados por dos o más tramos discontinuos aportando las mismas propiedades mecánicas requeridas que en el caso de un solo tramo continuo de bisagra.In the example shown here, hinge 23 presents a continuous tour although it will be evident for any subject matter expert who instead of a single continuous hinge, they can be formed by two or more discontinuous sections contributing the same mechanical properties required as in the case of a only continuous hinge section.
Con referencia a la figura 5 corresponde a una segunda realización de un envase obtenido por medio de un molde de inyección según la invención donde las mismas partes tienes referencias numéricas idénticas, cuya diferencia principal se localiza en el tramo inclinado que abarca toda la longitud de la pared lateral mayor indicado también con la referencia 24.With reference to figure 5 corresponds to a second embodiment of a container obtained by means of a mold of injection according to the invention where the same parts you have identical numerical references, whose main difference is locates in the inclined section that covers the entire length of the larger side wall also indicated with reference 24.
