Tapón de seguridad para envases flexibles.Safety cap for flexible packaging.

Objeto de la invenciónObject of the invention

La presente invención se refiere a un tapón de seguridad para envases flexibles, especialmente uno que es de indicada aplicación en los tubos flexibles de aluminio y de materiales plásticos sintéticos que contienen materiales cuya utilización requiere un cierto grado de profesionalidad, como son algunos de los adhesivos de polimerización rápida y muchas de las pomadas farmacéuticas, que no deben ser manipulados ni entrar en contacto con personas inexpertas, como pueden ser los niños.The present invention relates to a plug of security for flexible packaging, especially one that is indicated application in the flexible tubes of aluminum and synthetic plastic materials containing materials whose use requires a certain degree of professionalism, as they are some of the fast polymerization adhesives and many of the Pharmaceutical ointments, which should not be handled or entered into contact with inexperienced people, such as children.

Antecedentes de la invenciónBackground of the invention

Se tiene conocimiento de la existencia de una pluralidad de tapones de seguridad destinados a obturar recipientes del tipo de los frascos, que están constituidos por un casquillo de maniobra que aloja un casquillo de obturación complementario del gollete del frasco, presentando ambos casquillos una base plana cerrada en mutua correspondencia y medios de relación que permiten una ligera separación axial y el giro relativo, estando mediatizados dichos medios por medios de distanciación automática de las dos bases planas citadas, medios de arrastre giratorio unidireccional y medios de arrastre giratorio bidireccional, cooperando los medios de distanciación con los medios de arrastre unidireccional.There is knowledge of the existence of a plurality of safety caps intended for sealing containers of the type of the jars, which are constituted by a cap of maneuver that houses a complementary sealing sleeve of the flask of the bottle, presenting both caps a flat base closed in mutual correspondence and means of relationship that allow a slight axial separation and relative rotation, being mediated said means by means of automatic distance of the two aforementioned flat bases, rotating drive means Unidirectional and bi-directional rotating drag means, cooperating the means of distance with the means of drag unidirectional

Los medios de arrastre giratorio bidireccional están constituidos por sendas disposiciones de engrane situadas circunferencialmente en posición enfrentada en las caras adyacentes de las dos bases planas de los casquillos de maniobra y de obturación, de modo que el engrane se produce al vencer los medios de distanciación automática mediante el presionado axial del casquillo de maniobra contra el casquillo de obturación en la carrera permitida por los medios de relación.Bi-directional rotating dragging means they consist of two gear arrangements located circumferentially in facing position on adjacent faces of the two flat bases of the maneuver bushings and of shutter, so that the engagement occurs when the media beat automatic distance by axial pressing of operating sleeve against the sealing sleeve in the career allowed by the means of relationship.

Los medios de distanciación automática están constituidos por unas aletas flexibles inclinadas y dispuestas circunferencialmente que, solidarizadas por un extremo en la cara de la base plana de uno cualquiera de los casquillos, se aplican elásticamente por el borde opuesto en voladizo contra la cara enfrentada de la base plana del otro casquillo.The automatic distance means are consisting of inclined and arranged flexible fins circumferentially that, in solidarity with one end in the face of the flat base of any one of the bushings, apply elastically by the opposite edge cantilever against the face facing the flat base of the other bushing.

Por su parte los medios de arrastre giratorio unidireccional, en el sentido de obturación, están constituidos por unos relieves cuneiformes que, dispuestos circunferencialmente en la cara plana enfrentada a la cara plana de las aletas elásticas flexibles de los medios de distanciación automática, oponiendo un borde vertical de los mismos al borde en voladizo de las referidas aletas elásticas flexibles.On the other hand the means of rotating drag unidirectional, in the sense of shutter, are constituted by cuneiform reliefs that, arranged circumferentially in the flat face facing the flat face of the elastic fins flexible means of automatic distancing, opposing a vertical edge thereof to the cantilever edge of the referred flexible elastic fins.

Con los precedentes tapones, si se trata de aflojar el tapón para la apertura del frasco, el giro en el sentido inverso al de cierre resulta ineficaz, dado que las aletas flexibles se flexan al quedar aplicadas sobre los relieves superando a los mismos. En ello estriba precisamente la condición de seguridad del tapón, o sea que una manipulación normal del mismo en el sentido de apertura no proporciona resultado algu-
no.
With the previous caps, if it is a question of loosening the cap for opening the bottle, the rotation in the opposite direction to that of closing is inefficient, since the flexible fins flex when they are applied on the reliefs overcoming them. This is precisely the safety condition of the cap, that is to say that normal handling of the cap in the direction of opening does not give any result.
no.

Para conseguir la citada apertura debe procederse causando un empuje axial sobre el casquillo de maniobra contra el casquillo de obturación para conseguir el engrane de los rebordes del primero en los rebordes del segundo, venciendo la resistencia de las aletas flexibles y en esta situación realizar el giro normal de apertura, con lo que los primeros rebordes empujan a los segundos rebordes para el desenroscado de apertura consiguiente. Evidentemente, este proceder solo será realizado por personas conocedoras del procedimiento de apertura, lo que imposibilita o reduce las posibilidades de que los niños puedan realizar la apertura del frasco.To achieve the aforementioned opening must proceed causing an axial thrust on the bushing against the sealing sleeve to achieve flange engagement of the first on the flanges of the second, overcoming the resistance of the flexible fins and in this situation perform the normal rotation opening, so the first flanges push the second flanges for subsequent opening unscrewing. Obviously, this procedure will only be carried out by people aware of the opening procedure, which makes it impossible or reduces the chances that children can perform the bottle opening

Entre los tapones de seguridad que presentan las características expuestas precedentemente pueden citarse los modelos de utilidad nºs. 245.727, 291.125 y 9101286.Among the safety plugs that the characteristics set forth above may be cited utility models no. 245.727, 291.125 and 9101286.

A mayor abundamiento puede citarse el modelo de utilidad nº 287.969 según el cual un tapón de seguridad está constituido por un cuerpo que presenta una cavidad cilíndrica en la que puede enchufarse el correspondiente gollete de un frasco y en el interior del que ajusta, pudiendo deslizar a los largo de la misma, un disco obturador que es aplicado contra la boca del gollete por un muelle helicoidal que queda comprimido entre el mismo y el fondo de la cavidad, habiéndose previsto en uno de los indicados elementos al menos una regata en la que puede ajustar y a lo largo de la que puede deslizar un correspondiente pitón solidario del otro elemento, y presentando la regata, a partir del borde de aquel elemento, una forma acodada, de manera que el pitón queda retenido en el tramo extremo de la misma merced a la fuerza expansiva desarrollada por el muelle.To greater abundance the model of utility No. 287,969 according to which a safety plug is constituted by a body that has a cylindrical cavity in the that you can plug the corresponding neck of a bottle and in the interior of the adjuster, being able to slide along the same, a shutter disc that is applied against the mouth of the neck by a coil spring that is compressed between it and the bottom of the cavity, having been foreseen in one of the indicated elements at least one regatta in which you can adjust and to along which you can slide a corresponding python solidarity of the other element, and presenting the regatta, from the edge of that element, an angled shape, so that the python is retained in the extreme stretch of the same mercy by force expansive developed by the pier.
