Sector técnico de Ia invenciónTechnical sector of the invention
La presente invención se refiere al sector técnico de los precintos destinados a mantener Ia inviolabilidad de artículos transportados o manipulados y a almacenar y proporcionar información sobre el propio artículo y sobre el historial del mismo. Más específicamente, Ia presente invención se refiere a un precinto de alta seguri- dad, que comprende una tira flexible de plástico o similar, Ia cual está rematada en un ensanchamiento dotado de un regruesamiento atravesado por un canal, a través del que puede introducirse Ia tira a partir de su extremo libre, disponiendo el canal de medios de retención que permiten el paso de Ia tira en el sentido de introducción de Ia misma, pero impiden su desplazamiento en sentido contrario.The present invention relates to the technical sector of the seals intended to maintain the inviolability of items transported or handled and to store and provide information about the article itself and its history. More specifically, the present invention relates to a high security seal, which comprises a flexible plastic strip or the like, which is finished off in a widening provided with a thickening through a channel, through which the strip from its free end, providing the channel of retention means that allow the passage of the strip in the direction of introduction thereof, but prevent its displacement in the opposite direction.
Antecedentes de Ia invenciónBackground of the invention
Son conocidos en el sector técnico de los precintos de seguridad aquellos dispositivos de cierre de tipo brida que incluyen una tira alargada y flexible que se cierra formando un bucle sobre sí misma y queda retenida en dicha posición de cierre por medio de un acoplamiento de los dientes realizados en Ia tira y de unos medios de retención dispuestos en Ia ranura en Ia que se introduce Ia tira cuando se cierra el precinto. Este tipo de dispositivos de cierre permite garantizar parcial¬ mente Ia inviolabilidad del contenido del artículo o el recipiente precintados. Cuando el artículo o recipiente precintados se reciben con el dispositivo de cierre intacto, el receptor del artículo o recipiente tiene Ia seguridad de que no se han producido mo¬ dificaciones en los artículos precintados desde que se cerró el dispositivo ya que, como es sabido, el mismo- no es reutilizable. En el presente documento, a dichos dispositivos de seguridad se les denomina precintos.In the technical sector of safety seals, those flange-type closing devices are included, which include an elongated and flexible strip that closes forming a loop on itself and is retained in said closing position by means of a coupling of the teeth. made in the strip and with retention means arranged in the slot in which the strip is introduced when the seal is closed. This type of closing device allows partially guaranteeing the inviolability of the contents of the sealed article or container. When the sealed article or container is received with the closure device intact, the recipient of the article or container is assured that no modifications have been made to the sealed articles since the device was closed since, as is known, The same - it is not reusable. In this document, these security devices are called seals.
Por los modelos de utilidad ES-LM 027598 y ES-U-1030846, de los cuales es titular el mismo solicitante, se conocen sendos precintos de seguridad, constitui¬ dos por una brida flexible de plástico o similar, Ia cual queda rematada en un en¬ sanchamiento dotado de un pasaje a través del que puede introducirse Ia brida, a partir de su extremo libre, incluyendo el pasaje medios de retención de Ia brida,
dispuesíos en el interior de un alojamiento a tal efecto. Específicamente, el docu¬ mento ES-U-1027598 está "caracterizado porque el pasaje lleva montado una placa metálica transversal que dispone de una abertura, de cuyo contorno parten escota¬ duras o cortes aproximadamente radiales que delimitan pestañas o lengüetas in- termedias flexibles, las cuales están ligeramente inclinadas en un mismo sentido, a partir de su arranque; delimitando el borde interno de estas lengüetas un pasaje de contorno mínimo aproximadamente igual al de Ia sección de los tramos de Ia tira flexible carentes de encastres o dientes, pero inferior al delimitado por dichos en¬ castres o dientes; flexando las lengüetas o pestañas citadas en el sentido de su inclinación, para permitir el paso de los encastres o dientes de Ia tira flexible, mien¬ tras que en sentido contrario actúan como anclajes de retención, contra los que apoyan los encastres o dientes, impidiendo su retroceso.".For the utility models ES-LM 027598 and ES-U-1030846, of which the same applicant owns, two safety seals are known, constituted by a flexible plastic or similar flange, which is finished off in a en¬ sanchamiento provided with a passage through which the flange can be introduced, from its free end, including the passage means of retention of the flange, Arrangements inside a housing for this purpose. Specifically, document ES-U-1027598 is "characterized in that the passage is mounted on a transverse metal plate that has an opening, the contours of which are notched or roughly radial cuts that delimit flexible intermediate tabs or tabs, which are slightly inclined in the same direction, from their start; delimiting the internal edge of these tabs a minimum contour passage approximately equal to that of the section of the sections of the flexible strip lacking inserts or teeth, but less than delimited by said braces or teeth; flexing the tongues or tabs mentioned in the direction of their inclination, to allow the passage of the inserts or teeth of the flexible strip, while in the opposite direction they act as retention anchors, against those who support the inserts or teeth, preventing their recoil. "
Uno de los inconvenientes de que adolecen este tipo de precintos hasta ahora conocidos, es que aplicando calor a Ia zona de cierre del dispositivo, por ejemplo con un simple secador de pelo, se puede conseguir que Ia ranura de inser¬ ción de Ia tira se dilate suficientemente como para retirar dicha tira sin causar des¬ perfectos en el material. A continuación, y con Ia tira introducida nuevamente en el precinto, se puede hacer que Ia ranura recupere sustancialmente su forma original con Io cual el destinatario del artículo no tiene conocimiento de que su contenido ha sido violado.One of the disadvantages of this type of seals known so far, is that by applying heat to the closing area of the device, for example with a simple hair dryer, it is possible to achieve that the slot for inserting the strip is dilate sufficiently to remove said strip without causing flaws in the material. Then, and with the strip inserted back into the seal, the groove can be made to substantially recover its original form, with which the recipient of the article is not aware that its content has been violated.
La presente invención plantea una mejora con respecto a los precintos men¬ cionados de manera que los medios de retención que mantienen Ia tira en su posi¬ ción de cierre son metálicos con Io cual Ia aplicación de calor no consigue deformar¬ los suficientemente como para extraer Ia cinta. El calor necesario para dilatar dichos medios metálicos destruiría totalmente Ia parte normalmente plástica del resto del precinto con Io cual quedaría patente el intento de acceder al contenido del artículo precintado.The present invention proposes an improvement with respect to the aforementioned seals so that the retention means that hold the strip in its closed position are metallic, whereby the application of heat does not deform sufficiently enough to extract The tape. The heat necessary to dilate said metal means would completely destroy the normally plastic part of the rest of the seal with which the attempt to access the contents of the sealed article would be evident.

Descripción detallada de los dibujosFig. 9 is a top view of the box shown in Figs 6 and 8. Detailed description of the drawings
En dichos dibujos puede apreciarse una forma de realización de Ia presente invención.In said drawings an embodiment of the present invention can be seen.
En cuanto sigue se describe un ejemplo de realización del precinto de alta seguridad 1 de Ia presente invención.As soon as an example of embodiment of the high security seal 1 of the present invention is described.
En las Figs. 1 a y 1 b pueden apreciarse unas vistas en perspectiva del pre¬ cinto 1 en Ia posición de abertura y de cierre respectivamente. La estructura externa de dicho precinto 1 es similar a Ia correspondiente a los precintos de este tipo co¬ nocidos. El precinto 1 comprende esencialmente una tira flexible 2, un ensancha¬ miento 3, un regruesamiento 4 y un canal 5 en el regruesamiento 4 para el paso de Ia tira 2. Estos son los componentes básicos comunes a todos los precintos de este tipo de Ia técnica anterior. Tal como es sabido, estos precintos funcionan de manera que Ia tira flexible 2 se introduce a través del canal 5 del regruesamiento 4, y dicho canal o ranura 5 dispone de unos medios de retención que permiten el avance de Ia tira 2 pero evitan Ia extracción de Ia misma.In Figs. 1 a and 1 b, perspective views of the seal 1 can be seen in the opening and closing position respectively. The external structure of said seal 1 is similar to that corresponding to known seals of this type. The seal 1 essentially comprises a flexible strip 2, a widening 3, a thickening 4 and a channel 5 in the thickening 4 for the passage of the strip 2. These are the basic components common to all seals of this type of Ia prior art As it is known, these seals work so that the flexible strip 2 is introduced through the channel 5 of the thickening 4, and said channel or slot 5 has retention means that allow the advance of the strip 2 but prevent the extraction of it.
Estos medios de retención son el elemento que constituye Ia novedad con respecto a los dispositivos conocidos. En el caso de Ia presente invención, en el regruesamiento 4 se realiza un receptáculo 5 adaptado para contener un bloque o cajetín 8. A su vez, este cajetín 8 tiene insertada en su interior, de forma rígida, es decir, sin posibilidad de desplazamiento, una armadura de retención 10, preferen¬ temente metálica. En Ia Fig. 6 se ha representado Ia armadura de retención 10, habiéndose omitido en las Figs. 7 a 9 por motivos de claridad.These retention means are the element that constitutes the novelty with respect to the known devices. In the case of the present invention, in the thickening 4 a receptacle 5 adapted to contain a block or box 8 is made. In turn, this box 8 has rigidly inserted inside it, that is, without the possibility of displacement , a retaining frame 10, preferably metal. In Fig. 6, the retention reinforcement 10 is shown, having been omitted in Figs. 7 to 9 for reasons of clarity.
De forma similar, el receptáculo 5 así como el cajetín 8 están adaptados pa- ra que este último quede alojado en el interior del primero también sin posibilidad de desplazamiento mutuo.Similarly, the receptacle 5 as well as the box 8 are adapted so that the latter is housed inside the former also without the possibility of mutual displacement.
En Ia forma de realización preferida de Ia presente invención, este bloqueo del cajetín 8 dentro del receptáculo 5 se consigue con un sistema de enclavamiento por arpón 11. El arpón 11 forma parte del cajetín 8, tal como puede verse claramen- te en las Figs. 6 a 9, y dicho arpón 11 queda enclavado en un alojamiento 13 reali¬ zado en el regruesamiento 4 a continuación del receptáculo 7. Al mismo tiempo el canal 9 del cajetín 8 debe coincidir con el canal 5 del regruesamiento 4; de esta manera se crea un conducto a través del cual puede pasar Ia tira 2.
La armadura de retención 10 esta dispuesta en el interior del cajetín 8 de forma que parte de ella, o algunos elementos de Ia misma a modo de dientes, so¬ bresalen ligeramente por el contorno del canal 9 y, por Io tanto, del canal 5. La parte de Ia armadura de retención metálica 10 que sobresale es Ia adecuada para dejar pasar Ia tira 2 en el sentido de cierre del precinto 1 pero para evitar Ia retirada de dicha tira 2 en el sentido opuesto. Esto se puede conseguir de manera que dicha parte o dientes estén inclinados en el sentido de avance de Ia tira 2 con Io cual, cuando se intenta extraer dicha tira 2, estos dientes se "clavan" en el material plás¬ tico de Ia misma y no permiten su retroceso. En Ia mayoría de los precintos de Ia técnica anterior, esta retención de Ia tiraIn the preferred embodiment of the present invention, this blockage of the box 8 inside the receptacle 5 is achieved with a locking system by harpoon 11. The harpoon 11 is part of the box 8, as can be clearly seen in Figs. . 6 to 9, and said harpoon 11 is embedded in a housing 13 made in the thickening 4 following the receptacle 7. At the same time the channel 9 of the box 8 must coincide with the channel 5 of the thickening 4; in this way a duct is created through which strip 2 can pass. The retaining frame 10 is arranged inside the box 8 so that part of it, or some elements thereof as teeth, protrude slightly along the contour of the channel 9 and, therefore, of the channel 5 The part of the metal retaining reinforcement 10 that protrudes is suitable to allow the strip 2 to pass in the direction of closure of the seal 1 but to avoid the removal of said strip 2 in the opposite direction. This can be achieved so that said part or teeth are inclined in the direction of advance of the strip 2 whereby, when trying to extract said strip 2, these teeth are "stuck" in the plastic material thereof and They do not allow its recoil. In most of the seals of the prior art, this retention of the strip
2 se consigue con un acoplamiento mutuo de relieves plásticos realizados en Ia tira 2 del mismo material que todo el precinto 1. Se ha descubierto que con Ia aplicación de calor, es posible dilatar Ia ranura 5 (que también es de material plástico) y pue¬ den hacer correr Ia tira 2 para abrir el precinto 1. A continuación, volviendo a aplicar calor, pueden devolver Ia forma original al precinto 1 con Io cual resulta muy difícil, y a veces imposible, detectar una posible violación del contenido a proteger.2 is achieved with a mutual coupling of plastic reliefs made in strip 2 of the same material as the entire seal 1. It has been discovered that with the application of heat, it is possible to dilate the groove 5 (which is also made of plastic material) and can ¬ Den run strip 2 to open the seal 1. Then, by reapplying heat, they can return the original form to seal 1 with which it is very difficult, and sometimes impossible, to detect a possible violation of the content to be protected.
El precinto 1 de Ia presente invención evita este tipo de intrusión al introducir una armadura de retención metálica 10 que se puede considerar insensible a Ia aplicación de calor en cuanto a Ia variación de sus dimensiones. De esta manera, incluso a temperaturas bastante elevadas que normalmente consiguen dilatar mate¬ riales plásticos, Ia armadura de retención 10 permanece siempre enclavada en Ia tira 2 y se evita Ia extracción de esta última. Esto permite superar los inconvenien¬ tes de Ia técnica anterior.The seal 1 of the present invention avoids this type of intrusion by introducing a metal retention reinforcement 10 that can be considered insensitive to the application of heat in terms of the variation in its dimensions. In this way, even at quite high temperatures that normally manage to expand plastic materials, the retention frame 10 always remains locked in the strip 2 and the removal of the latter is avoided. This allows to overcome the drawbacks of the prior art.
La forma y los materiales de los componentes de este sistema de retención no son esenciales para cumplir el objetivo de Ia presente invención siempre que el material de Ia armadura de retención 10 tenga un coeficiente de dilatación mucho mayor que el del receptáculo 7 y el regruesamiento 4, y, en general, de todo el pre¬ cinto 1. De este modo se evita que dicho precinto 1 pueda ser abierto con Ia simple aplicación de calor. En Ia forma de realización preferida de Ia invención, Ia tira flexible 2 es plana con unos bordes longitudinales 12 dotados de regruesamientos circulares y, eviden¬ temente, los canales 5 y 9 tienen una forma correspondiente para dejar pasar dicha tira 2. La armadura de retención 10 insertada rígidamente en el cajetín 8 también
esíá adaptada para aplicar sus dientes, y, por Io tanto, su acción de retención, so¬ bre dichos regruesamientos de los bordes longitudinales 12 de Ia tira flexible 2.The shape and materials of the components of this retention system are not essential to fulfill the objective of the present invention provided that the material of the retention reinforcement 10 has a coefficient of expansion much greater than that of the receptacle 7 and the thickening 4 , and, in general, of the entire seal 1. In this way it is avoided that said seal 1 can be opened with the simple application of heat. In the preferred embodiment of the invention, the flexible strip 2 is flat with longitudinal edges 12 provided with circular thickening and, obviously, the channels 5 and 9 have a corresponding shape to let said strip 2 pass. retention 10 rigidly inserted in the box 8 also It is adapted to apply its teeth, and, therefore, its retention action, on said thickening of the longitudinal edges 12 of the flexible strip 2.
Descrita suficientemente la naturaleza de Ia presente invención, así como Ia manera de ponerla en práctica, se hace constar que todo cuanto no altere, cambie o modifique su principio fundamental, puede quedar sujeto a variaciones de detalle.
Describing sufficiently the nature of the present invention, as well as the way of putting it into practice, it is stated that everything that does not alter, change or modify its fundamental principle may be subject to variations in detail.
