El documento US-B-6279779 describe un dispositivo de apertura que se puede cerrar que tiene un marco que define un orificio pasante y se encaja alrededor de una zona perforable de un paquete sellado para productos alimenticios vertibles; un tapón de rosca retirable que se enrosca al marco para cerrar el orificio; y un miembro de corte tubular, que se acopla al orificio de manera móvil a lo largo de una trayectoria de alimentación en espiral, se conecta angularmente al tapón durante la desunión del tapón respecto el marco cuando se abre por primera vez el paquete, y tiene un borde extremo que tiene a su vez, en su cara, un único cortador que actúa sobre una zona mayor de la periferia de la zona perforable para abrir el paquete. El cortador se define por un diente formado en el borde extremo del miembro de corte y que tiene un perfil sustancialmente triangular definido por un borde de corte transversal a la zona perforable de la pared, y por un borde de corte lateral que tiene un perfil curvado inclinado con respecto al eje del dispositivo y que conecta un extremo libre del borde de corte al borde extremo. Más específicamente, el cortador comprende una zona de corte que sobresale axialmente con respecto al borde extremo y definido, hacia el interior del miembro de corte, por una superficie ligeramente inclinada con respecto a la zona perforable para definir una sección transversal de la zona de corte decreciente hacia la zona perforable. Adyacente al cortador, el borde extremo del miembro de corte tiene un rebaje en forma de rampa que aumenta en profundidad hacia el cortador y que define una altura axial del borde de corte mayor que la altura axial de la zona de corte.US-B-6279779 discloses a closable opening device having a frame defining a through hole and fitting around a pierceable area of a sealed package for pourable food products; a removable screw cap that screws into the frame to close the hole; and a tubular cutting member, which engages the orifice movably along a spiral feed path, is angularly connected to the cap during disengagement of the cap from the frame when the package is first opened, and has an end edge which in turn has, on its face, a single cutter that acts on a larger area of the periphery of the pierceable area to open the package. The cutter is defined by a tooth formed at the end edge of the cutting member and having a substantially triangular profile defined by a cutting edge transverse to the pierceable area of the wall, and by a lateral cutting edge having a curved profile. inclined with respect to the axis of the device and connecting a free end of the cutting edge to the extreme edge. More specifically, the cutter comprises a cutting area protruding axially with respect to the end edge and defined, towards the interior of the cutting member, by a slightly inclined surface with respect to the pierceable area to define a cross section of the cutting area. decreasing towards the pierceable zone. Adjacent to the cutter, the end edge of the cutting member has a ramp-shaped recess that increases in depth toward the cutter and defines an axial height of the cutting edge greater than the axial height of the cutting zone.
El documento US-A1-2004/0149786 describe un complemento de espita de vertido que se dispone sobre un punto perforable de una caja de cartón llena y sellada. El complemento comprende una espita de vertido bridada, un tapón de rosca y un elemento perforador anular. Las roscas se utilizan para desplazar el elemento perforador, que está abierto en ambos extremos, hacia abajo en dirección axial de manera helicoidal bajo la acción de desenroscar el tapón. El elemento perforador tiene dos dientes de corte desplazados en un ángulo que producen líneas de corte continuas e interconectadas, y un diente de desplazamiento que desplaza un disco parcialmente recortado de la caja de cartón desde la región de la espita. Cada diente de corte tiene un ápice afilado precedido por un borde de cuchilla.US-A1-2004 / 0149786 describes a pouring spout attachment which is arranged on a pierceable point of a filled and sealed carton. The accessory comprises a flanged spout, a screw cap, and an annular piercing element. The threads are used to move the piercing element, which is open at both ends, downward in the axial direction in a helical manner under the action of unscrewing the cap. The piercing element has two cutter teeth offset at an angle that produce continuous, interconnected cut lines, and a offset tooth that moves a partially cut disk of the carton from the spigot region. Each cutting tooth has a sharp apex preceded by a razor edge.
El documento US-A1-2005/0242113 describe un complemento de espita de vertido que comprende una espita que tiene una brida inferior que se va a moldear o pegar a un paquete compuesto, un tapón de rosca asociado, así como un manguito de apertura de caja de cartón dispuesto dentro de la espita. Se puede hacer que este manguito sea rotado por el tapón de rosca al desenroscarlo. La superficie interna de la espita se provee de cuatro bandas de guía que tienen inclinaciones variables dispuestas sobre su circunferencia interna. Estos interactúan con nervaduras de guía especialmente formadas en la pared exterior del manguito, de modo que el manguito, cuando es rotado continuamente en el interior de la espita, y al ser guiado por estas nervaduras, describe un movimiento desigual dirigido hacia abajo, superpuesto a su movimiento de rotación. Por lo tanto, el manguito perfora primero un laminado de papel o cartón del paquete con la punta de un único diente perforador del mismo en un movimiento empinado, dirigido hacia abajo, y luego realiza un movimiento de rotación horizontal de aproximadamente 340°, mientras corta parte de un disco circular del laminado con un borde de corte afilado, y luego pivota esta parte del disco hacia abajo y la retiene en esa posición. US-A1-2005 / 0242113 discloses a pouring spout attachment comprising a spout having a lower flange to be molded or glued to a composite pack, an associated screw cap, as well as an opening sleeve of cardboard box arranged inside the spigot. This sleeve can be made to be rotated by the screw cap by unscrewing it. The inner surface of the spout is provided with four guide bands having varying inclinations arranged on its inner circumference. These interact with specially formed guide ribs on the outer wall of the sleeve, so that the sleeve, when continuously rotated within the spigot, and being guided by these ribs, describes an uneven downward movement, superimposed on its rotational movement. Therefore, the sleeve first pierces a package paper or cardboard laminate with the tip of a single piercing tooth thereof in a steep, downward motion, and then performs a horizontal rotational motion of approximately 340 °, while cutting part of a circular laminate disk with a sharp cutting edge, and then pivots this part of the disk downward and holds it in position.

y en donde dicho giro de dicho cortador forma a través de dicha pared un corte de carácter de bucle abierto. and wherein said rotation of said cutter forms through said wall an open loop character cut.
Según un cuarto aspecto de la presente invención, se proporciona un método para abrir un paquete que comprende una caja de cartón formada de un laminado; y un complemento de espita de vertido unido a una pared de dicho cartón y que comprende una espita de vertido anular, un cortador anular que comprende un cuerpo anular, un diente que sobresale de un extremo axial de dicho cuerpo, dicho diente, en su punta, es en forma curvada de borde de cuchilla circunferencialmente a dicho cuerpo anular, dicho cortador es sustancialmente coaxial con dicha espita de vertido, un tapón montado en dicha espita para poder girar alrededor del eje de dicha espita para girar dicho cortador alrededor de dicho eje de modo que dicho borde de cuchilla adelantado precede a dicha punta, y una disposición de guiado de movimiento efectiva entre dicha espita y dicho cortador de tal manera que dicho cortador puede ser desplazado axialmente lejos de dicho tapón y girando alrededor de dicho eje con dicho borde de cuchilla que precede a dicha punta, que comprende girar dicho cortador alrededor de dicho eje para formar a través de dicha pared un corte de carácter de bucle abierto, dicho diente tiende a deslizarse sobre dicha pared cuando dicho diente corta dicha pared, en lugar de cavar en dicha pared.According to a fourth aspect of the present invention, there is provided a method for opening a package comprising a carton formed from a laminate; and a pouring spout complement attached to a wall of said cardboard and comprising an annular pouring spout, an annular cutter comprising an annular body, a tooth protruding from an axial end of said body, said tooth, at its tip , is in curved blade edge shape circumferentially to said annular body, said cutter is substantially coaxial with said pour spout, a plug mounted on said spout to be able to rotate around the axis of said spout to rotate said cutter around said spout axis such that said leading blade edge precedes said tip, and an effective movement guiding arrangement between said spout and said cutter such that said cutter can be axially displaced away from said plug and rotated about said axis with said edge of blade preceding said tip, comprising rotating said cutter around said axis to form a loop character cut through said wall open, said tooth tends to slide on said wall when said tooth cuts said wall, instead of digging into said wall.
Debido a esos aspectos de la invención, debido a que el diente, en su punta, tiene una forma curvada de borde de cuchilla circunferencialmente al cuerpo anular, es posible disponer que cave en la pared de paquete para cortarlo y por lo tanto que desgarre la pared, dejando bordes antiestéticos e incluso zonas arrancadas que pueden entrar en el contenido de la caja de cartón que va a ser verter o se está vertiendo, en lugar de cortar de manera relativamente limpia a través de la pared. Entre los expertos en la técnica, a veces existe una disputa sobre si el verbo "cortar" está restringido a la acción habitual de un cuchilla, o si también abarca empujar sobre el material de paquete para provocar que el material se fracture a lo largo de un línea, ya sea curvada o recta. En la presente Memoria descriptiva, el verbo (y sus sustantivos, adjetivos y adverbios correspondientes) se usa en un sentido más amplio, es decir, para abarcar ambas posibilidades.Due to these aspects of the invention, because the tooth, at its tip, has a curved blade edge shape circumferentially to the annular body, it is possible to arrange to dig into the wall of the package to cut it and thus tear the wall, leaving unsightly edges and even chipped areas that can get into the contents of the carton that is to be poured or is being poured, rather than cutting relatively cleanly through the wall. Among those skilled in the art, there is sometimes a dispute as to whether the verb "cut" is restricted to the usual action of a blade, or whether it also encompasses pushing on the package material to cause the material to fracture along a line, either curved or straight. In this Specification, the verb (and its corresponding nouns, adjectives and adverbs) is used in a broader sense, that is, to encompass both possibilities.
Ventajosamente, la forma curvada de borde de cuchilla es sustancialmente parte de una forma de onda sinusoidal. Además, el diente tiene ventajosamente un borde de cuchilla adelantado que se extiende oblicuamente alejándose de la punta hacia el cuerpo anular, siendo el borde delantero de cuchilla preferiblemente otra parte de la forma de onda sinusoidal. En una realización preferida, el diente, visto radialmente del cuerpo anular, es sustancialmente la mitad de la forma de onda sinusoidal. Ventajosamente, un complemento de espita de vertido que incluye el cortador anular comprende una espita de vertido anular sustancialmente coaxial con el cortador, un tapón montado en la espita para girar el cortador alrededor del eje de modo que el borde de cuchilla adelantado precede a la punta del diente, y alguna disposición de guiado de movimiento eficaz entre la espita y el cortador de manera que el cortador pueda ser desplazado tanto axialmente lejos del tapón como girando alrededor del eje con el borde de cuchilla adelantado que precede a la punta. Ventajosamente, al girar el tapón, la disposición de guiado de movimiento hace que el cortador se desplace simultáneamente axialmente lejos del tapón y girando alrededor del eje con el borde de cuchilla adelantado que precede a la punta. Advantageously, the curved blade edge shape is substantially part of a sinusoidal waveform. Furthermore, the tooth advantageously has a leading blade edge extending obliquely away from the tip towards the annular body, the leading blade edge preferably being another part of the sinusoidal waveform. In a preferred embodiment, the tooth, viewed radially from the annular body, is substantially one half of the sinusoidal waveform. Advantageously, a pouring spout complement including the annular cutter comprises an annular pouring spout substantially coaxial with the cutter, a plug mounted on the spout to rotate the cutter about the axis so that the leading blade edge precedes the tip. of the tooth, and some effective motion guiding arrangement between the spout and the cutter so that the cutter can be moved both axially away from the plug and rotated about the axis with the leading blade edge preceding the tip. Advantageously, as the plug rotates, the motion guiding arrangement causes the cutter to simultaneously move axially away from the plug and rotating about the axis with the leading blade edge preceding the tip.
Para que la invención pueda divulgarse clara y completamente, a continuación se hará referencia, a modo de ejemplo, a los dibujos adjuntos, en los que:In order that the invention may be clearly and fully disclosed, reference will now be made, by way of example, to the accompanying drawings, in which:

Con referencia a los dibujos, el complemento de espita de vertido es del carácter general descrito en el documento US-A-2004/0149786, con la gran diferencia de que el cortador anular (referenciado aquí 2) tiene un único diente (referenciado aquí 4) que cuelga de un cuerpo anular (referenciado aquí 6) del cortador 2. El cuerpo anular 6 está formado externamente periféricamente con rosca de tornillo 8 para cooperar con la rosca interna de la espita de vertido. El diente 4, en su punta 10, tiene una forma curvada de borde de cuchilla circunferencialmente al cuerpo anular 6. El diente 4 también tiene un borde de cuchilla adelantado 12 que se extiende oblicuamente hacia arriba desde la punta 10 hacia el cuerpo 6. El diente 4, como se ve radialmente del cuerpo 6, es sustancialmente la mitad de una forma de onda sinusoidal, como se indica en la Figura 2. Como se puede ver en la Figura 3, una extensión imaginaria 12' del borde de cuchilla 12 en un sentido alejándose del cuerpo 6 está en ángulo oblicuo hacia fuera.With reference to the drawings, the pouring spout complement is of the general nature described in document US-A-2004/0149786, with the great difference that the annular cutter (referenced here 2) has a single tooth (referenced here 4 ) hanging from an annular body (referenced here 6) of the cutter 2. The annular body 6 is formed externally peripherally with screw thread 8 to cooperate with the internal thread of the pouring spout. The tooth 4, at its tip 10, has a curved blade edge shape circumferentially to the annular body 6. The tooth 4 also has a leading blade edge 12 that extends obliquely upward from the tip 10 towards the body 6. The Tooth 4, as seen radially from body 6, is substantially one half of a sinusoidal waveform, as indicated in Figure 2. As can be seen in Figure 3, an imaginary extension 12 'of blade edge 12 at a sense away from the body 6 is obliquely outward.
Como se puede ver en las Figuras 3 y 4, el borde de cuchilla adelantado 12 está achaflanado en ambos lados 12a y 12b del mismo.As can be seen in Figures 3 and 4, the leading blade edge 12 is chamfered on both sides 12a and 12b thereof.
Con referencia a la Figura 5, se ve una superficie interior de una caja de cartón formada por un laminado 14 que comprende un sustrato de cartón con capas más internas y más externas de termoplásticos de barrera contra la humedad, posiblemente con la interposición de una capa de barrera contra el oxígeno. En la Figura 5, el cuerpo anular 6 y su diente 4, así como la espita de vertido 16 son visibles. Se puede ver que el diente 4 ha cortado desde la pared 14 y ha desviado hacia adentro un segmento principal 18 de un disco. Esa etapa final se ha alcanzado desenroscando el tapón de rosca del complemento de espita de vertido, con el resultado de que el diente 4 se mueve hacia abajo y gira alrededor del eje del complemento y presiona hacia abajo sobre el laminado 14 y, especialmente si el laminado 14 contiene una capa de barrera al oxígeno relativamente resistente, tensa esa capa de barrera para promover la acción de corte del diente 4. La forma de la punta 10 y del borde adelantado 12 del diente 4 son tales que el diente tiende a deslizarse sobre la pared a medida que lo corta, en lugar de cavar en ella. En la posición relativa final del diente 4 como se ve en la Figura 5, el segmento 18 está ubicado hacia fuera del diente 4. Suponiendo que el diente gira en una trayectoria circular, el ángulo de corte por el diente 4 es, por supuesto, menos de 360°, preferiblemente aproximadamente 300°, produciendo un corte pasante en forma de bucle abierto. Sin embargo, si el diente girara en una trayectoria en espiral, el ángulo de corte podría ser superior a 360°, produciéndose así un corte pasante en forma de bucle abierto. La plataforma de prueba 20 se ve alrededor de la parte expuesta de la pared 14. With reference to Figure 5, an inner surface of a cardboard box formed by a laminate 14 is seen comprising a cardboard substrate with innermost and outermost layers of moisture barrier thermoplastics, possibly with the interposition of a layer barrier against oxygen. In Figure 5, the annular body 6 and its tooth 4, as well as the pouring spout 16 are visible. It can be seen that tooth 4 has cut from wall 14 and deflected a major segment 18 of a disc inward. That final stage has been achieved by unscrewing the screw cap from the pouring spigot insert, with the result that tooth 4 moves down and rotates around the axis of the insert and presses down on laminate 14 and, especially if the Laminate 14 contains a relatively strong oxygen barrier layer, tightens that barrier layer to promote the cutting action of tooth 4. The shape of the tip 10 and leading edge 12 of tooth 4 are such that the tooth tends to slide over the wall as you cut it, rather than digging into it. In the final relative position of tooth 4 as seen in Figure 5, segment 18 is located away from tooth 4. Assuming that the tooth rotates in a circular path, the angle of cut through tooth 4 is, of course, less than 360 °, preferably about 300 °, producing an open loop through cut. However, if the tooth were to rotate in a spiral path, the cutting angle could be greater than 360 °, thus producing a through cut in the form of an open loop. The test platform 20 is seen around the exposed portion of the wall 14.
