La invención se refiere a una botella fabricada en material plástico con un fondo reforzado, producida utilizando la técnica de soplado de una pieza en bruto inicial o "parisón" extrusionado o coextrusionado de polietileno de alta densidad (HDPE) u otro material apropiado y particularmente adecuado para el envasado estéril de líquidos para productos alimenticios, o para otros usos en los que se requieren condiciones de envasado estéril, por ejemplo, para el envasado de líquidos para usos cosméticos, farmacéuticos o similares.The invention relates to a manufactured bottle in plastic material with a reinforced bottom, produced using the Blowing technique of an initial blank or "parisón" extruded or coextruded of high density polyethylene (HDPE) or other appropriate and particularly suitable material for the sterile packaging of liquids for food products, or for other uses where sterile packaging conditions are required, for example, for the packaging of liquids for cosmetic uses, Pharmacists or similar.
Se conoce como fabricar estas botellas, proporcionando a su fondo una forma rebajada y apropiadamente cóncava con nervios de refuerzo, con el objeto de garantizar la no deformabilidad del propio fondo de la botella, tanto durante la fase de fabricación como en la fase de utilización, cuando la propia botella está cargada con el peso del producto envasado y está sometida a las vibraciones y tensiones mecánicas que se generan durante las diversas fases del transporte: ver la patente USA-A-3 403 804. En la tecnología conocida se han apreciado problemas con la estanqueidad del fondo de las botellas, debido a la aparición a largo plazo de pequeñas grietas en la zona en la que dichos nervios de refuerzo se unen al fondo de la botella y asimismo se han hallado problemas de deformación de la parte lateral inferior de la misma botella durante las fases finales del proceso de termoformado de la propia botella mediante soplado, tal como se especifica mejor a continuación. La intención de la invención es superar estos inconvenientes de la tecnología conocida con las soluciones indicadas en las reivindicaciones adjuntas, cuyas características y ventajas se harán evidentes a partir de la siguiente descripción realizada haciendo referencia a las figuras de las cinco páginas de dibujos adjuntos, en los cuales:It is known as making these bottles, providing your bottom with a lowered and properly shaped concave with reinforcement ribs, in order to guarantee the deformability of the bottom of the bottle, both during the phase of manufacturing as in the phase of use, when the own bottle is loaded with the weight of the packaged product and is subjected to the vibrations and mechanical stresses that are generated during the various phases of transport: see the patent USA-A-3 403 804. In technology known problems have been seen with the tightness of the bottom of the bottles, due to the long-term appearance of small cracks in the area where said reinforcing nerves join the bottom of the bottle and problems have also been found deformation of the lower side part of the same bottle during the final phases of the thermoforming process of the bottle itself by blowing, as specified below. The The intention of the invention is to overcome these drawbacks of the known technology with the solutions indicated in the attached claims, whose characteristics and advantages will be made evident from the following description made by reference to the figures on the five pages of attached drawings, in which:

La botella (1), ilustrada en la figura 1, ha sido fabricada utilizando la tecnología conocida de termoformado mediante soplado, partiendo de un parisón de HDPE formado, por ejemplo, a partir de varias capas coextrusionadas, dispuestas verticalmente con su propio eje longitudinal, el cual en la fase adecuada está encerrado entre dos partes simétricas y complementarias de un molde que define el negativo de la forma de la futura botella con sus cavidades internas y que, con sus propios medios, cierra los extremos opuestos del parisón con un cierre completo del extremo inferior destinado a formar el fondo de la botella y con un cierre parcial del extremo superior, para permitir el paso de una aguja conectada a un circuito que, en la fase adecuada, insufla aire a presión en el parisón, obligando al propio parisón a hincharse y a adherirse a las paredes interiores de las dos partes del molde para adoptar la forma establecida de la botella (1). Cuando, como en el caso en cuestión, la botella está destinada al envasado estéril de productos de alimentación, cosméticos o de otro tipo, dicha operación de soplado utiliza aire esterilizado. A continuación de la fase de formación, se abren las dos partes del molde, y estando la botella conectada todavía a la aguja de soplado es sometida a ensayo habitualmente con respecto a su estanqueidad y a cualquier otra característica de calidad, y a continuación es extraída de la aguja y transferida al proceso de eliminación del residuo de colada inferior. Si las botellas han sido insufladas utilizando aire estéril, únicamente se elimina dicho aire de la aguja de soplado cuando su colada superior (101) ha sido aplastada y cerrada de forma hermética en la zona intermedia (101'), y después de haber creado un vacío en las propias botellas capaz de compensar el incremento futuro de presión producido por el calor residual en el material plástico que constituye las propias botellas. La boca superior de las botellas será abierta durante la fase siguiente de llenado del producto, llevado a cabo en un entorno con una atmósfera controlada. En esta fase, se elimina la totalidad de la parte superior de la botella indicada en la figura 1 mediante la línea de trazos y mediante (101) y, después del llenado, se cierra la botella herméticamente con un tapón de rosca, no mostrado en los dibujos, roscado a la boca (201) con rosca exterior de la propia botella. Se entiende que la forma y las dimensiones de la botella pueden ser diferentes de las ilustradas en la figura 1.The bottle (1), illustrated in Figure 1, has been manufactured using known thermoforming technology by blowing, starting from a parison of HDPE formed, by example, from several coextruded layers, arranged vertically with its own longitudinal axis, which in the phase proper is enclosed between two symmetric parts and complementary to a mold that defines the negative of the shape of the future bottle with its internal cavities and that, with its own means, close the opposite ends of the parisón with a closure complete bottom end intended to form the bottom of the bottle and with a partial closure of the upper end, to allow the passage of a needle connected to a circuit that, in the phase adequate, blows air under pressure in the parisón, forcing itself parisón to swell and adhere to the interior walls of the Two parts of the mold to adopt the established shape of the bottle (one). When, as in the case in question, the bottle is intended to sterile packaging of food products, cosmetics or another type, said blowing operation uses sterilized air. TO continuation of the training phase, the two parts of the mold, and the bottle still connected to the blowing needle It is usually tested for its tightness and to any other quality feature, and below is removed from the needle and transferred to the process of elimination of the lower wash residue. If the bottles have been blown using sterile air, only said air is removed from the blowing needle when its upper wash (101) has been crushed and hermetically sealed in the intermediate zone (101 '), and then having created a vacuum in the bottles themselves capable of compensating the future increase in pressure produced by the residual heat in the plastic material that constitutes the bottles themselves. Mouth The top of the bottles will be opened during the next phase of product filling, carried out in an environment with an atmosphere controlled. In this phase, the entire part is eliminated top of the bottle indicated in figure 1 by the line of strokes and by (101) and, after filling, the bottle is closed tightly with a screw cap, not shown in the drawings, threaded to the mouth (201) with external thread of the bottle itself. Be understand that the shape and dimensions of the bottle can be different from those illustrated in figure 1.
Las botellas (1) en cuestión tienen un fondo (301) con un ligero rebaje y con la forma de una tapa esférica, y dichas dos partes de un molde que forman la botella tienen partes inferiores, cada una de las cuales define la forma del fondo (301) y que pueden desplazarse en sentido vertical en comparación con cada una de las partes superiores del molde, con la consecuencia lógica de que estas partes móviles generalmente están levantadas en la fase inicial de cierre de las dos partes del molde. Cuando se ha completado la conformación de la botella, se abren las dos partes del molde con un ligero desplazamiento horizontal separándose mutuamente, de modo que sus partes móviles del fondo quedan liberadas del contacto con la colada inferior y pueden descender para salir de la muesca formada por el fondo de la botella, después de lo cual dichas dos partes del molde completan la fase de apertura para permitir la extracción de la botella.The bottles (1) in question have a bottom (301) with a slight recess and in the shape of a spherical cap, and said two parts of a mold that form the bottle have parts lower, each of which defines the shape of the fund (301) and that can scroll vertically compared to each one of the upper parts of the mold, with the logical consequence that these moving parts are generally raised in the phase Initial closure of the two parts of the mold. When has Once the bottle has been formed, the two parts are opened of the mold with a slight horizontal displacement separating each other, so that your moving parts of the fund remain freed from contact with the lower laundry and may descend to leave the notch formed by the bottom of the bottle, then of which said two parts of the mold complete the phase of opening to allow the extraction of the bottle.
Durante la fase de formación de la botella en dichas partes del molde, se obtienen unos nervios lineales (2) en el fondo (301) de la propia botella, en relieve hacia el exterior (figuras 2 y 3), paralelos entre sí y dispuestos de manera simétrica, y siendo, por ejemplo, en número de cinco o en otro número, preferentemente impar, de tal manera que uno de estos nervios está situado en la línea central del fondo de la botella y que estos nervios están orientados perpendicularmente en comparación con el plano vertical ideal sobre el que reposa la parte aplastada (101') de la colada superior (101) de la botella y, por consiguiente, orientados con su eje longitudinal en la misma dirección que el movimiento horizontal relativo de aproximación y separación de las dos partes principales del molde entre las cuales se ha formado la botella. Los nervios (2) tienen un perfil transversal y exterior curvado (102), con un radio de curvatura apropiado y los propios nervios están conectados a la cara inferior del fondo (301) con una línea (202) apropiadamente en forma de radio, tal como se ilustra en detalle en la figura 3a, con el objeto de impedir que se produzcan dichos fenómenos de agrietado durante la fase de enfriamiento del material del que están compuestos. Los nervios (2) tienen una sección intermedia con lados substancialmente paralelos y una profundidad substancialmente constante, y terminan con unos extremos progresivamente cónicos y con una profundidad decreciente, por consiguiente con una forma puntiaguda, situados a la distancia adecuada de la parte perimetral (401) con la cual el fondo de la botella está destinado a entrar en contacto con una superficie de soporte.During the bottle formation phase in said parts of the mold, linear ribs (2) are obtained in the bottom (301) of the bottle itself, embossed outwards (Figures 2 and 3), parallel to each other and arranged so symmetric, and being, for example, in number of five or in another number, preferably odd, such that one of these nerves is located in the center line of the bottom of the bottle and that these nerves are oriented perpendicularly in comparison with the ideal vertical plane on which the crushed part rests (101 ') of the upper wash (101) of the bottle and, for consequently, oriented with its longitudinal axis therein direction that the relative horizontal approach movement and separation of the two main parts of the mold between which The bottle has formed. The nerves (2) have a profile transverse and curved exterior (102), with a radius of curvature appropriate and the nerves themselves are connected to the lower face from the bottom (301) with a line (202) appropriately in the form of radius, as illustrated in detail in figure 3a, with the object to prevent such cracking phenomena from occurring during the cooling phase of the material of which they are composed. The nerves (2) have an intermediate section with substantially sides parallels and a substantially constant depth, and end with progressively tapered ends and with a depth decreasing, therefore with a pointed shape, located at the appropriate distance from the perimeter part (401) with which the Bottom of the bottle is intended to come into contact with a support surface.
Durante la misma fase de formación de los nervios (2), se obtiene un nervio (3) perpendicularmente a los mismos y en la línea central del fondo de la botella, el cual es adyacente y está alineado con la colada inferior de la propia botella, y se compone de una parte inferior (103) que está en contacto con el fondo de la botella y tiene una profundidad y una anchura exterior que son constantes en toda su longitud y con unos valores que son iguales o ligeramente superiores que los de las secciones intermedias de dichos nervios (2), y se cruza y está fijado a dichos nervios y sobrepasa a los nervios exteriores (2), con unas secciones cortas (103'), tal como puede apreciarse en las figuras 2 y 3. En dicha parte inferior (103), y a lo largo de toda su longitud, el nervio central (3) comprende un reborde central (203) de una anchura (A) limitada, por ejemplo, a un valor de 1/3 aproximadamente de la anchura (B) de la parte inferior (103) del propio nervio, el cual, visto lateralmente como en la figura 3, tiene un perfil ligeramente arqueado que termina con una forma redondeada apropiada en los extremos asimismo redondeados de la propia parte inferior (103) del nervio central. Una de las funciones del reborde (203) es reforzar de manera adicional el nervio central (3), mientras que otra función importante es dispersar el calor para garantizar un enfriamiento rápido y equilibrado tanto del nervio central (3) como de los nervios (2) perpendiculares al mismo y conectados estructuralmente entre sí.During the same phase of formation of nerves (2), a nerve (3) is obtained perpendicular to the themselves and in the center line of the bottom of the bottle, which is adjacent and is aligned with the lower wash of the own bottle, and consists of a bottom (103) that is in contact with the bottom of the bottle and has a depth and a exterior width that are constant throughout its length and with about values that are equal to or slightly higher than those of intermediate sections of said nerves (2), and it crosses and is fixed to said nerves and exceeds the outer nerves (2), with short sections (103 '), as can be seen in the Figures 2 and 3. In said lower part (103), and throughout its length, the central nerve (3) comprises a central flange (203) of a limited width (A), for example, to a value of 1/3 approximately of the width (B) of the lower part (103) of the own nerve, which, seen laterally as in figure 3, It has a slightly arched profile that ends with a shape appropriate rounded at the equally rounded ends of the own lower part (103) of the central nerve. One of the functions of the flange (203) is to further strengthen the central nerve (3), while another important function is to disperse heat to ensure a fast and balanced cooling of both the nerve central (3) as of the nerves (2) perpendicular to it and structurally connected to each other.
A partir del detalle de la figura 4a puede apreciarse que el nervio central (3) tiene en conjunto una sección transversal substancialmente en forma de Y, y que está conectado asimismo al fondo (301) de la botella mediante su propia parte inferior (103), con una línea exterior (303) con una forma de radio apropiada, que impide la formación de grietas durante la fase de enfriamiento del propio nervio (3). Las zonas de conexión (403) entre la parte (103) y la parte (203) del nervio (3) tienen también unos radios apropiados, mientras que el borde longitudinal (503) del reborde (203) está asimismo redondeado de manera apropiada.From the detail of figure 4a you can it can be seen that the central nerve (3) has a section together substantially Y-shaped, and that is connected also at the bottom (301) of the bottle through its own part bottom (103), with an outside line (303) with a radius shape appropriate, which prevents the formation of cracks during the phase of cooling of the nerve itself (3). Connection areas (403) between part (103) and part (203) of the nerve (3) they also have appropriate radii, while the longitudinal edge (503) of the flange (203) is also appropriately rounded.
El número (4) en las figuras 2, 3 y 4 indica dos pequeñas cavidades hundidas en el borde perimetral de soporte del fondo de la botella, alineadas con el nervio central (3) mencionado anteriormente y destinadas a cooperar con medios que son adecuados para impedir la rotación de la propia botella durante la fase en la que se está cerrando por la parte superior mediante el tapón de rosca.The number (4) in Figures 2, 3 and 4 indicates two small cavities sunk in the perimeter support edge of the Bottom of the bottle, aligned with the central nerve (3) mentioned previously and intended to cooperate with means that are appropriate to prevent rotation of the bottle itself during the phase in the which is closing at the top by means of the thread.
La figura 5 ilustra la parte del fondo de una botella en la cual, según una técnica de construcción conocida, el borde perimetral de soporte (401') del fondo de la propia botella tiene una anchura considerable en sentido radial. Este borde con una anchura considerable puede torcerse en sentido descendente y alargar la botella de una manera permanente y anómala durante la fase en que se está cerrando y en la que se está creando el vacío en ella, de manera que se compensa el incremento de la propia presión interior producida por el calor residual del proceso de termoformado por soplado. Esta deformación está indicada mediante la línea de trazos e implica asimismo a la pared lateral (501) de la botella que se caracteriza por un gran radio de curvatura y por una considerable altura en la sección incluida entre dicho borde (401') y la primera parte nervada (601) de la propia pared lateral de la botella. Se pretende que la invención supere este inconveniente mediante la solución ilustrada en las figuras 1 a 4, según las cuales se incrementa la curvatura del fondo (301) en comparación con la tecnología conocida, de tal manera que se reduce la anchura del borde de soporte (401) a una pequeña parte con un perfil redondeado y tangencial a la pared lateral (701), la cual tiene un radio de curvatura (R) menor que el de la tecnología conocida, y tiene una altura que es asimismo inferior a la de la tecnología conocida ilustrada en la figura 5 y finaliza en concordancia con una parte (801) de la propia pared lateral, que está nervada mediante el correspondiente escalón de ensanchamiento en sentido descendente, todo lo cual de tal manera que la pared (701) realizada de este modo y conectada a las partes (401) y (801) tiene una resistencia a la torsión considerable, tanto hacia el interior como hacia el exterior de la botella, solucionando completamente dichos inconvenientes de la tecnología conocida.Figure 5 illustrates the bottom part of a bottle in which, according to a known construction technique, the perimeter support edge (401 ') of the bottom of the bottle itself It has a considerable width radially. This edge with a considerable width can be twisted down and lengthen the bottle in a permanent and anomalous way during the phase in which is closing and in which the void is being created in it, of so that the increase in the internal pressure itself is compensated produced by the residual heat of the thermoforming process by blown. This deformation is indicated by the dashed line. and also involves the side wall (501) of the bottle that is characterized by a large radius of curvature and a considerable height in the section included between said edge (401 ') and the first ribbed part (601) of the bottle side wall itself. Be It is intended that the invention overcome this drawback by means of solution illustrated in figures 1 to 4, according to which increases the curvature of the bottom (301) compared to the known technology, such that the width of the support edge (401) to a small part with a rounded profile and tangential to the side wall (701), which has a radius of curvature (R) smaller than that of known technology, and has a height that is also lower than that of known technology illustrated in figure 5 and ends in accordance with a part (801) of the side wall itself, which is veined by the corresponding step of widening downwards, all of which in such a way that the wall (701) realized in this way and connected to the parts (401) and (801) has a resistance to considerable torsion, both inward and outward of the bottle, completely solving these inconveniences of The known technology.
En la botella tal como ha sido descrita, puede suceder que en algunas condiciones de utilización particularmente extremas la zona entre el borde (401) y los extremos de los nervios (2) y (3) puede torcerse hacia el exterior, mientras que la pared del fondo (301) desciende de manera proporcional. Es posible solucionar este problema con una botella mejorada, tal como se describirá a continuación haciendo referencia a las figuras 6 a 11. En las botellas (1') con fondos con un plano redondeado, como en el ejemplo de las figuras 6, 7 y 8, la anchura del borde de soporte (401') es mayor si se la compara con la (401) de la solución anterior como en las figuras 1 a 3, y esto en perjuicio de la anchura de la parte rebajada del fondo (301'), que está afectada por los nervios de refuerzo (2) y (3), que pueden ser menores que (301) que proporciona la anterior solución. El borde (401') tiene ahora forma de radio, con un amplio radio de curvatura, con el perfil de la pared lateral inferior (701') de la botella, mientras que el extremo interior del mismo borde (401') está conectado de manera disjunta ("disjointed") a la tapa esférica (301') en el fondo de la botella, con un borde en forma de cono truncado (901'), cuya generatriz forma un ángulo (\alpha) que mide menos de 90º con respecto a la horizontal y que preferentemente está comprendido entre 40 y 60º, por ejemplo, unos 48º.In the bottle as described, you can happen that in some conditions of use particularly extremes the area between the edge (401) and the ends of the nerves (2) and (3) can be twisted outward while the wall from the bottom (301) descends proportionally. it's possible solve this problem with an improved bottle, as will describe below with reference to figures 6 to 11. In bottles (1 ') with bottoms with a rounded plane, as in the example of figures 6, 7 and 8, the width of the support edge (401 ') is greater if compared to (401) of the solution above as in figures 1 to 3, and this to the detriment of the width of the recessed part of the bottom (301 '), which is affected by the reinforcing nerves (2) and (3), which may be less than (301) which provides the previous solution. The edge (401 ') has now radio shape, with a wide radius of curvature, with the profile of the lower side wall (701 ') of the bottle, while the inner end of the same edge (401 ') is connected so disjointed ("disjointed") to the spherical cover (301 ') at the bottom of the bottle, with a truncated cone-shaped edge (901 '), whose generatrix forms an angle (?) that measures less than 90º with with respect to the horizontal and which is preferably comprised between 40 and 60º, for example, about 48º.
El número (5) indica la línea cerrada de límite entre dicho borde (901') en forma de cono truncado y la tapa (301') en el fondo de la botella, que en este ejemplo consiste en una circunferencia. Los nervios (2) de refuerzo están situados con sus extremos casi en contacto con dicha circunferencia (5) y están distribuidos a una distancia mutua mayor que la de la solución anterior mostrada en las figuras 1 a 3, de tal manera que sus extremos (103') que sobresalen del nervio diametral (3) están asimismo a una corta distancia de dicha circunferencia (5). En la nueva solución comentada en esta descripción, la distancia de separación entre los nervios (2) es substancialmente igual al valor que se obtiene dividiendo el diámetro de la circunferencia (5) por el número de los propios nervios, de modo que la distancia entre los nervios (2) situados más al exterior comparada con las zonas de la circunferencia (5) que están cerca de los rebajes (4) es substancialmente igual a la separación entre los propios nervios (2).The number (5) indicates the closed limit line between said edge (901 ') in the form of a truncated cone and the cover (301') at the bottom of the bottle, which in this example consists of a circumference. The reinforcing ribs (2) are located with their ends almost in contact with said circumference (5) and are distributed at a mutual distance greater than that of the solution above shown in figures 1 to 3, such that their ends (103 ') protruding from the diametral nerve (3) are also a short distance from said circumference (5). In the new solution discussed in this description, the distance of separation between nerves (2) is substantially equal to the value which is obtained by dividing the diameter of the circumference (5) by the number of the nerves themselves, so that the distance between the nerves (2) located more outside compared to the areas of the circumference (5) that are close to the recesses (4) is substantially equal to the separation between the nerves themselves (2).
Las mejoras descritas con referencia a las figuras 6 a 8 son válidas para todas las botellas con cuerpos con una sección redondeada o con una sección poligonal regular tendiendo a una sección redondeada. En el caso en que la sección de la botella (1') es substancialmente cuadrada con lados y esquinas redondeados, como en el ejemplo de la figura 6, esta misma sección está conectada a la parte del fondo que comprende el borde (401'), con una parte (10) con un plano cuadrado con esquinas y lados adecuadamente redondeados, la cual está inscrita en la sección del cuerpo de la botella (1') y está girada 90º con respecto al mismo.The improvements described with reference to Figures 6 to 8 are valid for all bottles with bodies with a rounded section or with a regular polygonal section tending to a rounded section. In the case where the bottle section (1 ') is substantially square with rounded sides and corners, as in the example of figure 6, this same section is connected to the part of the bottom comprising the edge (401 '), with a part (10) with a square plane with corners and sides properly rounded, which is inscribed in the body section of the bottle (1 ') and is rotated 90º with respect to it.
Cuando el fondo de la botella (1'') tiene un plano ovalado, como en el ejemplo de las figuras 9 a 11, el borde de soporte inferior (401'') del fondo de la propia botella tiene un perfil y una conexión exterior a la pared lateral inferior (701'') que son muy similares a los de la solución anterior a la que se hace referencia en las figuras 1 a 3, pero en este caso el borde de soporte (401'') está conectado asimismo interiormente a la pared (301'') del fondo en forma de arco, en este caso con un plano ovalado, con un borde inclinado (901'') cuya generatriz en coincidencia con los rebajes (4) forma un ángulo (\alpha') de 45º a 50º aproximadamente, por ejemplo, de unos 48º con la horizontal (figura 10), mientras que coincidiendo con los extremos del nervio ecuatorial (2), la generatriz del mismo borde (901'') forma un ángulo (\alpha'') de 50º a 55º aproximadamente, por ejemplo, de unos 53º (figura 11) con la horizontal.When the bottom of the bottle (1 '') has a oval plane, as in the example of figures 9 to 11, the edge of bottom support (401 '') from the bottom of the bottle itself has a profile and an external connection to the lower side wall (701``) which are very similar to those of the previous solution to the one made reference in figures 1 to 3, but in this case the edge of support (401 '') is also connected internally to the wall (301 '') of the arch-shaped bottom, in this case with a plane oval, with an inclined edge (901``) whose generatrix in coincidence with the recesses (4) forms an angle (α ') of 45 ° at 50º approximately, for example, about 48º with the horizontal (figure 10), while coinciding with the nerve ends equatorial (2), the generatrix of the same edge (901 '') forms a angle (?) of approximately 50 ° to 55 °, for example, of about 53º (figure 11) with the horizontal.
En lo que se refiere al posicionado de los nervios (2) y (3) en comparación con la línea de límite (5) del borde inclinado (901''), es válido lo que se ha manifestado para la solución a la que se hace referencia en las figuras 6 a 8.Regarding the positioning of the nerves (2) and (3) compared to the boundary line (5) of the sloping edge (901 ''), what has been stated for the solution referred to in figures 6 to 8.
