US-A-6,086,523 discloses a pouring spout accessory that has an annular flange and an integral and removable membrane with a pull lug. The membrane has a weakened peripheral line attached to an inward projection, located halfway along the inner wall of the pitorro. The lower end of the pitorro can have a continuous internal heel to be frictionally coupled, releasably, to a spigot of application of the accessory, which is inserted into the lower end of the pitorro. The pitorro has a cover provided with thread fillets and elastic jump adjustment, with a band that shows improper handling. Instead of a continuous internal heel, it is possible to employ a ring of segments that extend peripherally with respect to the spout, or a ring of vertical ribs formed such that they extend upwardly from a position adjacent to the bottom edge of the spout.

El documento GB-A-2.396.151 divulga un sistema de cierre integralmente moldeado y que evidencia la manipulacion indebida, destinado a formar un accesorio de pitorro de vertido y que comprende una tapa, un cuello provisto de brida y medios que evidencian la manipulacion indebida. La estructura permite la aplicacion de la tapa al cuello presionando axialmente, uno contra otro, la tapa y el cuello, con lo que los medios que evidencian la manipulacion indebida impiden que la tapa sea retirada del cuello, en tanto que los medios que evidencian la manipulacion indebida permanecen intactos. El sistema de cierre incluye medios de transition entre la parte superior del cuello y la parte inferior de una banda de los medios de evidencia de manipulacion indebida, una pared de bloqueo y unos filetes de rosca correspondientes, de tal manera que los medios de transicion estan fijados al cuello por un acoplamiento rompible, y pueden venir proporcionados por una pluralidad de elementos espaciados separados por aberturas, o bien pueden incluir uno o mas pliegues o dobleces. Con el sistema de cierre en el estado ensamblado, el accesorio puede ser aplicado a un carton de una manera convencional. El interior del extremo inferior del cuello viene definido por una superficie inclinada hacia abajo y radialmente hacia fuera, que facilita la insertion de una espita de un aplicador del accesorio. Una pluralidad de lenguetas espaciadas circunferencialmente y que sobresalen radialmente hacia dentro facilitan la retention del accesorio en la espita. El accesorio puede ser adherido al exterior o al interior de un panel de carton, segun se desee.Document GB-A-2,396,151 discloses an integrally molded closure system that evidences undue manipulation, intended to form a spout piping accessory and comprising a cover, a neck provided with a flange and means evidencing undue manipulation . The structure allows the application of the cap to the neck by pressing axially, against each other, the cap and the neck, whereby the means evidencing the improper manipulation prevent the cap from being removed from the neck, while the means evidencing the improper handling remain intact. The closure system includes means of transition between the upper part of the neck and the lower part of a band of tamper evident means, a blocking wall and corresponding thread fillets, such that the transition means are fixed to the neck by a breakable coupling, and may be provided by a plurality of spaced elements separated by openings, or they may include one or more folds or folds. With the closure system in the assembled state, the accessory can be applied to a cardboard in a conventional manner. The inside of the lower end of the neck is defined by a surface tilted downward and radially outward, which facilitates the insertion of a spigot of an attachment applicator. A plurality of circumferentially spaced and radially protruding tongues facilitate retention of the attachment in the spigot. The accessory can be attached to the outside or inside a cardboard panel, as desired.

El documento US 2004/0245262 A1 divulga un pitorro de vertido provisto de una brida, dentro del cual se ha dispuesto al menos un saliente, en una superficie interna del pitorro de vertido, a fin de retener de forma liberable el pitorro de vertido en una espita que se utiliza para aplicar el pitorro de vertido a la pared de un recipiente. Esta divulgation reconoce como conocida una version en la que el saliente adopta la forma de un talon o labio anular alrededor de un borde interno inferior del pitorro de vertido, as! como otra version en la que se han proporcionado varios salientes separados entre si, en forma de talon, distribuidos en la circunferencia del pitorro, en su superficie interna y cerca del borde interno inferior. La divulgacion explica que, si los pitorros de vertido son de diferentes tamanos, deben cambiarse las espitas que sujetan estos pitorros, debido a que un tamano de pitorro dado unicamente puede ser sujetado en una espita conjugada adecuada, extiendo tan solo un pequeno juego con el fin de, por una parte, garantizar la retencion y el transporte del pitorro de vertido en la espita, a la vez que, por otra parte, se facilite una facil retirada de la espita del pitorro aplicado. La divulgacion explica, de manera adicional, que el cambio de las espitas para adaptarse a tamanos de pitorro diferentes lleva una relativa cantidad de tiempo y esfuerzo y reduce significativamente la productividad, y que incluso dimensiones ligeramente diferentes que se producen durante la fabrication de un mismo tipo de pitorro de vertido pueden traer consigo disfunciones durante el ensamblaje, ya que el pitorro, bien se desliza entonces con demasiada facilidad con respecto a la espita, o bien es sujetado demasiado fuertemente en la espita. Esta divulgacion propone que el, o cada, saliente debe tener la forma de un tabique susceptible de ser doblado y que es oblicuo a la superficie interna del pitorro de vertido, a saber, se encuentra en un angulo menor que 90° y mayor que 0° con respecto a esta.Document US 2004/0245262 A1 discloses a pouring spout provided with a flange, within which at least one projection is disposed, on an internal surface of the pouring spout, in order to releasably retain the spout spout in a tap that is used to apply the pouring spout to the wall of a container. This disclosure recognizes as known a version in which the protrusion takes the form of a heel or annular lip around a lower inner edge of the spout, as! as another version in which several protrusions separated from each other have been provided, in the form of a heel, distributed in the circumference of the spout, on its inner surface and near the lower inner edge. The disclosure explains that, if the spouts are of different sizes, the spindles that hold these spouts must be changed, because a given spout size can only be held in a suitable conjugated spigot, extending only a small play with the in order, on the one hand, to guarantee the retention and transport of the spout in the spigot, while, on the other hand, an easy removal of the spout from the spout applied is facilitated. The disclosure explains, additionally, that changing the spikes to adapt to different sizes of pitorro takes a relative amount of time and effort and significantly reduces productivity, and that even slightly different dimensions that occur during the manufacture of the same The type of spout can lead to malfunctions during assembly, since the spout, either then slides too easily with respect to the spigot, or is held too tightly in the spigot. This disclosure proposes that the, or each, protrusion must have the form of a partition that can be folded and that is oblique to the internal surface of the spout, namely, is at an angle less than 90 ° and greater than 0 ° regarding this.

El documento US 2003/0071042 A1 divulga un accesorio que incluye una brida de pitorro, un pitorro, una membrana rompible y un miembro de agarre. El pitorro sobresale hacia arriba desde la brida de pitorro y tiene unas porciones cillndricas superior e inferior, de las cuales la inferior tiene un area de section transversal de flujo pasante que es mayor que la de la superior, de tal manera que se forma un hombro interno entre ellas. La membrana rompible obtura por completo el pitorro en la portion cillndrica superior y tiene un borde periferico que esta unido a la superficie periferica interior de esa porcion superior a lo largo de una llnea debilitada. El miembro de agarre se ha configurado para facilitar la retirada de la membrana rompible del pitorro. Un proposito de esta invencion anterior es proporcionar un miembro de agarre mejorado con el fin de facilitar la apertura inicial del accesorio por parte de un usuario. Sin embargo, se divulgan realizaciones en las que, de manera adicional, el accesorio tiene una estructura de acoplamiento con una espita, en un caso, en el extremo inferior del pitorro y en la forma de prominencias discretas para acoplamiento con protuberancias, que son de forma sustancialmente semicircular, y, en otro caso, en la forma de chavetas de acoplamiento con protuberancias que se extienden verticalmente, las cuales se extienden radialmente hacia dentro desde la superficie periferica interior de la porcion superior cillndrica.US 2003/0071042 A1 discloses an accessory that includes a spout flange, a spout, a breakable membrane and a gripping member. The pitorro protrudes upward from the pitorro flange and has upper and lower cylindrical portions, of which the lower one has a cross-sectional cross-sectional area that is larger than the upper one, such that a shoulder is formed internal between them. The breakable membrane completely seals the spout in the upper cylindrical portion and has a peripheral edge that is attached to the inner peripheral surface of that upper portion along a weakened line. The grip member has been configured to facilitate removal of the breakable membrane from the spout. A purpose of this prior invention is to provide an improved grip member in order to facilitate the initial opening of the accessory by a user. However, embodiments are disclosed in which, additionally, the accessory has a coupling structure with a spigot, in one case, at the lower end of the spout and in the form of discrete prominences for coupling with protuberances, which are of substantially semicircular shape, and, in another case, in the form of coupling keys with vertically extending protrusions, which extend radially inwardly from the inner peripheral surface of the cylindrical upper portion.

una espita, que comprende producir un movimiento relativo axial entre el pitorro y la espita para hacer que una zona de extremo de avance de la espita entre en el pitorro y, por tanto, provoque un resalte de la espita que se extienda en torno a la espita para estrujar a su paso una serie de prominencias que se extienden desde una superficie periferica interna del pitorro y estan distribuidas en torno a dicha superficie, y para acoplarse de forma liberable por detras de dichas prominencias.a spigot, which comprises producing a relative axial movement between the spout and the spigot to cause a leading end zone of the spigot to enter the spout and, therefore, cause a spout of the spigot extending around the spout. It spits to squeeze in its path a series of prominences that extend from an inner peripheral surface of the pitorro and are distributed around said surface, and to engage releasably behind these prominences.

De acuerdo con un segundo aspecto de la presente invencion, se proporciona una combinacion que comprende una espita que incluye un resalte que se extiende en torno a ella, y un pitorro de vertido que incluye una serie de prominencias que se extienden desde una superficie periferica interna del pitorro y estan distribuidas en torno a esa superficie, de tal manera que el resalte tiene un radio maximo, desde un eje longitudinal de la espita, que es mayor que los radios desde ese eje de las porciones radialmente mas internas de las prominencias respectivas, y de modo que la espita puede insertarse dentro del pitorro de vertido lo suficientemente lejos para que las porciones radialmente mas exteriores del resalte queden situadas mas alla de dichas porciones radialmente mas interiores.According to a second aspect of the present invention, a combination is provided comprising a spigot that includes a projection that extends around it, and a pouring spout that includes a series of prominences that extend from an inner peripheral surface. of the pitorro and are distributed around that surface, so that the projection has a maximum radius, from a longitudinal axis of the spigot, which is greater than the radii from that axis of the radially innermost portions of the respective prominences, and so that the spigot can be inserted into the pouring spout far enough so that the radially outermost portions of the projection are located beyond said radially innermost portions.

En la combinacion, el pitorro de vertido puede comprender unas primera y segunda porciones cillndricas de las cuales la segunda porcion es de un area en seccion transversal de flujo pasante que es mayor que la de la primera porcion, un hombro interno entre las primera y segunda porciones, de tal manera que la serie de prominencias se extienden desde la superficie interna de la segunda porcion y estan distribuidas en torno a esa superficie, y de modo que las porciones radialmente mas interiores de las prominencias estan espaciadas con respecto al hombro interno.In combination, the pouring spout may comprise first and second cylindrical portions of which the second portion is of a cross-sectional area of through flow that is larger than that of the first portion, an internal shoulder between the first and second portions, such that the series of prominences extend from the inner surface of the second portion and are distributed around that surface, and so that the radially innermost portions of the prominences are spaced relative to the inner shoulder.

En virtud de la invencion, es posible mejorar la fiabilidad de retencion del pitorro de vertido en la espita, al tiempo que, sin embargo, se permite que el pitorro de vertido sea facilmente liberable con respecto a esta.By virtue of the invention, it is possible to improve the reliability of retention of the spout spout on the spout, while, however, the spout spout is allowed to be easily released with respect to this.

Ventajosamente, las prominencias son tales, que se deforman elasticamente a medida que el resalte pasa por ellas estrujandolas.Advantageously, the prominences are such that they deform elastically as the protrusion passes through them by squeezing them.

Preferiblemente, el resalte es anular y sustancialmente coaxial con la espita.Preferably, the shoulder is annular and substantially coaxial with the spigot.

Es ventajoso que las porciones radialmente mas interiores de las prominencias esten sustancialmente alineadas con la superficie periferica interna de la primera porcion del pitorro, a saber, la porcion que tiene el area de seccion transversal de flujo pasante mas pequena, ya que esto facilita el moldeo por inyeccion del pitorro de vertido, en comparacion con una disposicion en la que esas porciones radialmente mas interiores sobresalen significativamente hacia dentro mas alla de la superficie periferica interna de la primera porcion.It is advantageous that the radially innermost portions of the prominences are substantially aligned with the inner peripheral surface of the first portion of the pitorro, namely, the portion that has the smaller cross-sectional cross-sectional area, since this facilitates molding by injection of the pouring spout, in comparison with an arrangement in which those radially innermost portions protrude significantly beyond the inner peripheral surface of the first portion.

Las prominencias pueden adoptar la forma de nervaduras que se extienden longitudinalmente con respecto al pitorro de vertido, de tal manera que esas nervaduras pueden adoptar la forma de tiras, y las tiras pueden extenderse sustancialmente en planos axiales respectivos del pitorro de vertido. Estas caracterlsticas, de nuevo, facilitan el moldeo por inyeccion.The prominences may take the form of longitudinally extending ribs with respect to the pouring spout, such that these ribs may take the form of strips, and the strips may extend substantially in respective axial planes of the pouring spout. These features, again, facilitate injection molding.

A fin de que la invencion pueda describirse clara y exhaustivamente, se hara referencia a continuacion, a modo de ejemplo, a los dibujos que se acompanan, en los cuales:In order that the invention can be described clearly and thoroughly, reference will now be made, by way of example, to the accompanying drawings, in which:

La Figura 1 es una vista en corte axial a traves de un accesorio de pitorro de vertido; la Figura 1A muestra un detalle de la Figura 1, en la region circunscrita por llnea discontinua; la Figura 2 es una vista en planta inferior del accesorio de pitorro de vertido;Figure 1 is an axial sectional view through a pouring spout attachment; Figure 1A shows a detail of Figure 1, in the region circumscribed by a broken line; Figure 2 is a bottom plan view of the pouring spout attachment;

la Figura 3 es una vista en corte axial a traves del accesorio, y una vista en planta de una espita que se aproxima al accesorio; yFigure 3 is an axial sectional view through the fitting, and a plan view of a spigot approaching the fitting; Y

la Figura 4 se corresponde con la Figura 3, pero muestra la espita insertada dentro del accesorio.Figure 4 corresponds to Figure 3, but shows the tap inserted into the accessory.

Haciendo referencia a los dibujos, el accesorio 2 de pitorro de vertido incluye un pitorro de vertido 4 provisto de una brida, el cual comprende unas porciones superior e inferior, 6 y 8, sustancialmente cillndricas circulares, de las cuales la porcion inferior 8 es de un area de seccion transversal de flujo pasante que es mayor que la de la porcion superior 6. Existe, de esta manera, formado entre las porciones 6 y 8, un hombro interno 10. Una serie de prominencias 12 se extienden desde la superficie interna 14 de la porcion 8 y estan distribuidas en torno a esa superficie, de tal manera que las porciones radialmente mas interiores 16 de esas prominencias 12 estan separadas del hombro interno 10. Como puede observarse en la Figura 1A, estas porciones radialmente mas interiores 16 estan sustancialmente alineadas con la superficie periferica externa 18 de la porcion 6. Las prominencias 12 adoptan la forma de tiras de cierto perfil que se extienden en respectivos planos axiales del pitorro de vertido 4. El accesorio 2 de pitorro de vertido se completa con una tapa roscada 20 provista de una banda 22 de evidencia de manipulacion indebida.Referring to the drawings, the pouring spout accessory 2 includes a pouring spout 4 provided with a flange, which comprises upper and lower portions, 6 and 8, substantially circular cylindrical, of which the lower portion 8 is of a cross-sectional area of through flow that is larger than that of the upper portion 6. There is, thus, formed between portions 6 and 8, an internal shoulder 10. A series of prominences 12 extend from the internal surface 14 of the portion 8 and are distributed around that surface, such that the radially innermost portions 16 of those prominences 12 are separated from the inner shoulder 10. As can be seen in Figure 1A, these radially innermost portions 16 are substantially aligned with the outer peripheral surface 18 of the portion 6. The prominences 12 take the form of strips of a certain profile that extend in respective axial planes of the pitor pouring pipe 4. The pouring spout accessory 2 is completed with a threaded cap 20 provided with a band 22 of evidence of improper handling.

Haciendo referencia, en particular, a las Figuras 3 y 4, la espita 24 incluye un resalte anular 26 en derredor de ella, y tambien incluye una brida 28 y un teton internamente roscado 30, en virtud del cual la espita puede ser fijada de forma liberable a un brazo de un aplicador de accesorio de pitorro de vertido.Referring, in particular, to Figures 3 and 4, the spout 24 includes an annular shoulder 26 around it, and also includes a flange 28 and an internally threaded stud 30, by virtue of which the spigot can be fixed so releasable to one arm of a pouring spout accessory applicator.

Como se comprende facilmente por las personas con conocimientos ordinarios de la tecnica, para el montaje del accesorio 2 en la espita 24, una vez que el accesorio ha llegado al extremo inferior de una rampa de suministro y, de esta forma, esta listo para su montaje, la espita 24 es hecha avanzar al objeto de hacer que la zona del extremo de avance de la espita entre en el pitorro 4. Esto provoca que el resalte 26, que es de un radio maximo mayor que los 5 radios de las porciones radialmente mas interiores 16 de las prominencias 12, estruje las prominencias l2 a su paso por ellas de manera tal, que las prominencias se deforman elasticamente, y que se acople de forma liberable por detras de las prominencias 12, esto es, entre las prominencias 12, por una parte, y el hombro 10, por la otra parte, tal como se muestra en la Figura 4. La union entre el pitorro 4 y la espita 24 adopta la forma de una union de ajuste por salto elastico en la que el resalte 26 se ajusta entre el hombro 10 y las prominencias 12 y, de este modo, retiene 10 el accesorio 2 firmemente, pero de forma liberable, en su posicion durante su transferencia al recipiente, en la que el accesorio 2 es fijado, particularmente por ultrasonidos, al recipiente. Una parte cillndrica 32 de la zona de borde de avance de la espita 24 es recibida por la superficie periferica interna 18 de la porcion 6. Seguidamente a la soldadura por ultrasonidos de la brida del pitorro de vertido 4 de la superficie interna del panel del recipiente en cuestion, la espita 24 es retirada del accesorio 2, de modo que las prominencias 12 se deforman de nuevo 15 elasticamente, esta vez para permitir que el resalte 26 las estruje a su paso por ellas en la direccion opuesta.As is easily understood by persons with ordinary skill in the art, for mounting the accessory 2 on the spigot 24, once the accessory has reached the lower end of a supply ramp and is thus ready for assembly, the spigot 24 is advanced in order to make the area of the leading end of the spigot enter the spout 4. This causes the protrusion 26, which is a maximum radius greater than the 5 radii of the portions radially more interior 16 of the prominences 12, squeeze the prominences l2 as it passes through them in such a way that the prominences are elastically deformed, and that it is releasably coupled behind the prominences 12, that is, between the prominences 12, on the one hand, and the shoulder 10, on the other hand, as shown in Figure 4. The joint between the spout 4 and the spout 24 takes the form of an elastic jump adjustment joint in which the shoulder 26 fits between shoulder 10 and the s prominences 12 and, thus, 10 retains the accessory 2 firmly, but releasably, in its position during its transfer to the container, in which the accessory 2 is fixed, particularly by ultrasound, to the container. A cylindrical part 32 of the leading edge area of the spout 24 is received by the inner peripheral surface 18 of the portion 6. Following ultrasonic welding of the flange of the pouring spout 4 of the inner surface of the container panel in question, the spout 24 is removed from the accessory 2, so that the prominences 12 are elastically deformed again 15, this time to allow the protrusion 26 to squeeze them as it passes through them in the opposite direction.

Como consecuencia de la provision de las prominencias elasticas 12, el sistema descrito con referencia a los dibujos es capaz de manejar el juego variable requerido por un abanico de diferentes tipos de accesorios de pitorro de vertido, as! como las tolerancias de fabricacion de tales accesorios dentro de tipo concreto, al tiempo que el ajuste 20 por salto elastico del resalte 26 por detras de las prominencias y el encaje entre estas prominencias, por un lado, y el hombro interno 10, por otro lado, retienen el accesorio de forma mas fiable y mas firme en la espita 24 durante su extraccion de la rampa de calda y su transporte hasta el recipiente.As a consequence of the provision of elastic prominences 12, the system described with reference to the drawings is capable of handling the variable clearance required by a range of different types of pouring spout accessories, as! such as the manufacturing tolerances of such accessories within a concrete type, while the adjustment 20 by elastic jump of the shoulder 26 behind the prominences and the fit between these prominences, on the one hand, and the internal shoulder 10, on the other hand , they retain the accessory more reliably and firmly on the spout 24 during its removal from the broth ramp and transport it to the container.
