En la figura 1 se aprecia el aspecto exterior de la caperuza de cierre aplicada sobre el extremo de un envase -4- dotado de una valona -5- en el gollete. En dicha figura se aprecia el cuerpo inferior -1- y el cuerpo superior -3- de la caperuza de cierre objeto de la invención . Figure 1 shows the exterior appearance of the closure cap applied on the end of a container -4- provided with a wall -5- on the neck. In said figure the lower body -1- and the upper body -3- of the closing cap object of the invention can be seen.
En la figura 2 se aprecian los mismos elementos que en la figura 1 mostrándose desmontada la banda desprendible -6-, que constituye el precinto externo de la caperuza de cierre y presenta la parte del anillo periférico antideslizante del cuerpo intermedio -2-. El cuerpo intermedio -2- está fabricado de un color distinto al cuerpo superior -3- y cuerpo inferior -1- para que el usuario pueda observar rápidamente que la banda desprendible -6- ha sido desgarrada, al observar la diferencia de color entre los cuerpos En la figura 3 se aprecian los mismos elementos que en la figura 2, representando una tapa acharnelada -31- abierta mediante la ala de acharnelamiento -35-, permitiendo observar parte del cuerpo intermedio -2-. En la figura 4 se aprecian los mismos elementos que en la figura 3, mostrando la membrana de seguridad -8- con su anilla de extracción -9- manual desmontada, lo que permite observar parte de la disposición interna del cuerpo intermedio -2-. Figure 2 shows the same elements as in Figure 1 showing the removable strip -6-, which constitutes the outer seal of the closing cap and presents the part of the non-slip peripheral ring of the intermediate body -2-. The intermediate body -2- is made of a color different from the upper body -3- and lower body -1- so that the user can quickly see that the removable band -6- has been torn, when observing the difference in color between the bodies Figure 3 shows the same elements as in Figure 2, representing a flanged lid -31- opened by the flanging wing -35-, allowing to observe part of the intermediate body -2-. Figure 4 shows the same elements as in Figure 3, showing the safety membrane -8- with its manual removal ring -9- removed, which allows observing part of the internal arrangement of the body intermediate 2-.
En la figura 5 se aprecian elementos constructivos de la caperuza de cierre objeto de la presente invención en posición montada en una primera realización. Se debe observar que la caperuza se ha representado incorporada en el gollete superior de un envase destinado a contener un liquido, por ejemplo, un liquido de consumo, tal y como aceite, del que se ha representado una parte superior -4- y la valona -5-, que evidentemente no forman parte de la presente invención. Figure 5 shows construction elements of the closure cap object of the present invention in a position mounted in a first embodiment. It should be noted that the cap has been shown incorporated in the upper neck of a container intended to contain a liquid, for example, a consumption liquid, such as oil, of which a top part -4- and the wall has been represented -5-, which obviously are not part of the present invention.
Tal como se puede apreciar en la figura 6, el cuerpo inferior -1- presenta un faldón externo -10- sensiblemente cilindrico destinado a quedar acoplado sobre la parte exterior del gollete -11- del recipiente (ver figura 5) . Para la sujeción del cuerpo -1- sobre el gollete -11- del envase, dicho cuerpo inferior -1- presenta una banda flexible inferior -12- en forma de una ala interior rebatida hacia adentro y hacia arriba de características elásticas, que una vez introducida se engatilla con un relieve de la parte superior del gollete -11-, a efectos de su retención axial. Dicho cuerpo inferior -1- presenta en el interior de su faldón externo -10- un nervio -13- de tipo fijo, pero con características elásticas, que queda retenido de manera similar a la banda flexible inferior -12-, en un relieve del gollete -11-, tal como se puede apreciar en la figura 5. Por lo tanto, la fijación axial del cuerpo inferior -1- con respecto al envase, quedará asegurada por la acción combinada de retención de dicha banda flexible inferior -12- y nervio -13- con los relieves externos del gollete -11-. As can be seen in figure 6, the lower body -1- has an external skirt -10- substantially cylindrical intended to be coupled on the outside of the neck -11- of the container (see figure 5). For the fastening of the body -1- on the neck -11- of the container, said lower body -1- has a lower flexible band -12- in the form of an inner wing folded inwardly and upwardly of elastic characteristics, which once introduced is hooked with a relief from the top of the neck -11-, for the purpose of axial retention. Said lower body -1- presents within its external skirt -10- a fixed -13- nerve, but with elastic characteristics, which is retained similarly to the lower flexible band -12-, in a relief of the neck -11-, as can be seen in Figure 5. Therefore, the axial fixation of the lower body -1- with respect to the container, will be ensured by the combined retention action of said lower flexible band -12- and nerve -13- with the external reliefs of the neck -eleven-.
Interiormente, el cuerpo inferior -1- presenta en una primera realización, otros dos faldones internos -14- y -15- sensiblemente cilindricos, coaxiales con el faldón externo -10- y que se pueden observar en las figuras 5 y 6. El faldón interno -14- queda acoplado al interior del gollete -11- del envase y presenta un amplio nervio inferior -16- para asegurar la unión estanca del cuerpo inferior de la caperuza de cierre sobre el envase. Inwardly, the lower body -1- presents in a first embodiment, two other internal skirts -14- and -15- substantially cylindrical, coaxial with the external skirt -10- and which can be seen in Figures 5 and 6. The skirt Internal -14- is coupled to the inside of the neck -11- of the container and has a large lower rib -16- to ensure the tight connection of the lower body of the cap on the container.
En una primera realización el otro faldón interno -15- está destinado a recibir la parte correspondiente del cuerpo intermedio -2- y por su parte superior se une mediante la zona plana -17- con el faldón intermedio -14-, facilitando una zona de tope para el cuerpo intermedio -2-, tal como se explicará más adelante. En una primera realización el cuerpo inferior -1- del ejemplo presenta interiormente una superficie cónica radial -18- dotada de un saliente central -37- y de tres ventanas -19- radiales y de tres agujeros -39- de forma arcocircunferencial , tal como se aprecia en la figura 7. Dichas ventanas -19- tienen una disposición sensiblemente cónico radial y están destinadas a permitir la salida del liquido contenido en el recipiente sobre el que está aplicada la caperuza de cierre, combinándose con la acción de giro del cuerpo intermedio, para ajusfar el caudal vertido por la caperuza de cierre objeto de la invención en el momento del vaciado del envase. In a first embodiment, the other internal skirt -15- is intended to receive the corresponding part of the intermediate body -2- and, in its upper part, is joined by the flat area -17- with the intermediate skirt -14-, facilitating a zone of stop for intermediate body -2-, as will be explained later. In a first embodiment the lower body -1- of the example internally has a radial conical surface -18- provided with a central projection -37- and with three radial windows -19- and with three holes -39- of an arc-circumferential shape, such as It can be seen in Figure 7. Said windows -19- have a substantially conical radial arrangement and are intended to allow the liquid contained in the container on which the closure cap is applied to be combined, combined with the turning action of the intermediate body , to adjust the flow discharged by the closure cap object of the invention at the time of emptying the container.
En una primera realización el cuerpo intermedio -2- se aprecia en detalle en la figura 5, en la que se ha representado la sección completa de la caperuza de cierre y en las figuras 8 y 9, que muestran una vista en perspectiva seccionada y completa de dicho cuerpo intermedio -2-. Tal como se puede apreciar, dicho cuerpo intermedio tiene una parte cilindrica -20- que encaja en el borde inferior del faldón -15- del cuerpo inferior -1-, quedando retenido en el mismo mediante las patas de fijación -21- dotadas de un nervio saliente de retención -22- que queda encajado a través de los agujeros -39- en el borde inferior del faldón -15- impidiendo, después de su introducción por elasticidad, la salida axial de dicho cuerpo intermedio -2-, se puede ver los diferentes elementos en las figuras 6 y 7. Como se observa, los agujeros -39- presentan forma de una ranura arcocircunferencial . A lo largo de dichos agujeros pueden deslizar las patas de fijación -21- permitiendo de esta manera el giro del cuerpo intermedio -2- con respecto al cuerpo inferior -1- los agujeros -39- marcan el tope de giro del cuerpo intermedio -2-, con respecto al cuerpo inferior -1-. Dicho cuerpo intermedio presenta una membrana de seguridad -8- y una anilla de extracción -9-, que integran el precinto interno que deberá ser abierto mediante desgarro después de la apertura de la tapa de cierre para dar salida al contenido del envase. La parte cilindrica -20- del cuerpo intermedio presenta una amplia valona intermedia -23- que coincide, una vez montada, sobre la zona plana -17- del cuerpo inferior llegando, por lo tanto, a tope sobre ella cuando tiene lugar la introducción a presión del cuerpo intermedio dentro del cuerpo inferior. Dicha valona intermedia -23- presenta un anillo periférico -24- dotado de relieves antideslizantes -25- para permitir efectuar manualmente el giro del cuerpo intermedio -2- sobre el cuerpo inferior. Unas proyecciones cónico radiales -26- están dirigidas radialmente desde la parte cilindrica -20- hacia el interior del cuerpo intermedio. Dichas proyecciones cónico radiales -26- delimitan unas aberturas -38- entre ellas y presentan una forma inclinada correspondiente con las ventanas -19- y la superficie cónico radial -18- del cuerpo inferior -1-. Además dichas proyecciones cónico radiales -26- como se puede observar en las figuras 8 y 9, no están unidas entre si por su punto central, permitiendo asi el encaje con el saliente central -37- del cuerpo inferior. Según la posición de giro del cuerpo intermedio se varia el grado de obturación de dichas ventanas del cuerpo inferior. De esta manera, resulta muy fácil ajusfar la cantidad de caudal vertido por la caperuza de cierre objeto de la invención. In a first embodiment the intermediate body -2- can be seen in detail in Figure 5, in which the entire section of the closing cap has been shown and in Figures 8 and 9, which show a sectioned and complete perspective view of said intermediate body -2-. As can be seen, said intermediate body has a cylindrical part -20- that fits into the lower edge of the skirt -15- of the lower body -1-, being retained therein by means of the fixing legs -21- provided with a protrusion retaining rib -22- that fits through the holes -39- at the lower edge of the skirt -15- preventing, after its introduction by elasticity, the axial exit of said intermediate body -2-, can be seen the different elements in figures 6 and 7. As can be seen, the holes -39- have the shape of an arc-circumferential groove. Along these holes they can slide the fixing legs -21- thus allowing the rotation of the intermediate body -2- with respect to the lower body -1- the holes -39- mark the rotation stop of the intermediate body -2 -, with respect to the lower body -1-. Said intermediate body has a safety membrane -8- and an extraction ring -9-, which integrate the internal seal that must be opened by tearing after opening the closing lid to give out the contents of the container. The cylindrical part -20- of the intermediate body has a wide intermediate wall -23- that coincides, once mounted, on the flat area -17- of the lower body, thus reaching butt on it when the introduction to intermediate body pressure inside the lower body. Said intermediate wall -23- has a peripheral ring -24- provided with non-slip reliefs -25- to allow manually turning the intermediate body -2- over the lower body. Radial conical projections -26- are directed radially from the cylindrical part -20- into the interior of the intermediate body. Said radial conical projections -26- delimit openings -38- between them and have a corresponding inclined shape with the windows -19- and the radial conical surface -18- of the lower body -1-. Furthermore, said radial conical projections -26- as can be seen in Figures 8 and 9, are not joined together by their central point, thus allowing the fitting with the central projection -37- of the lower body. Depending on the rotation position of the intermediate body, the degree of sealing of said lower body windows is varied. In this way, it is very easy to adjust the amount of flow discharged by the closure cap object of the invention.
El cuerpo intermedio -2- termina en su parte cilindrica -20- en un ala periférica -27-, suavemente curvada hacia el exterior, para permitir el vertido del liquido contenido en el envase. The intermediate body -2- ends in its cylindrical part -20- in a peripheral wing -27-, gently curved outwards, to allow the pouring of the liquid contained in the container.
El cuerpo superior -3- representado en la figura 10 presenta una zona anular inferior -28- dotada interiormente de una banda flexible de retención -29- similar a la anteriormente descrita banda flexible inferior -12- del cuerpo inferior -1-, que está destinada a quedar retenida dentro del cuerpo intermedio, tal como es posible apreciar en la figura 5. Por encima de dicha parte anular -28- queda situada la banda desprendible -6- de la que continua la superficie lateral -30- de la tapa acharnelada -31-, que queda abisagrada a la parte anular -28- en la zona en la que no se extiende la banda desprendible -6-, determinando un ala de acharnelamiento -35-, figuras 3 y 4. Interiormente, la tapa acharnelada -31- presenta dos salientes cilindricos internos -33- y -32-, destinados a encajar respectivamente con la parte cilindrica -20- y la valona intermedia -23- del cuerpo intermedio, figuras 5 y 10. Dicha tapa acharnelada queda retenida en el cuerpo intermedio mediante la banda flexible de retención -29- y cierra de forma estanca con ayuda de un nervio interno -34- sobre la parte cilindrica -20- del cuerpo intermedio -2- de la caperuza de cierre, objeto de la invención. The upper body -3- shown in Figure 10 has a lower annular area -28- internally provided with a flexible retention band -29- similar to the previously described lower flexible band -12- of the lower body -1-, which is intended to be retained within the intermediate body, as can be seen in Figure 5. Above said annular part -28- is the removable strip -6- from which the lateral surface -30- of the flanged lid continues -31-, which is hinged to the annular part -28- in the area in which the removable band does not extend -6-, determining a flanging wing -35-, figures 3 and 4. Inside, the flanged cover -31- has two internal cylindrical projections -33- and -32-, intended to fit respectively with the cylindrical part -20- and the intermediate wall -23- of the body intermediate, figures 5 and 10. Said flanged lid is retained in the intermediate body by means of the flexible retention band -29- and closes tightly with the help of an internal rib -34- on the cylindrical part -20- of the intermediate body - 2- of the closing cap, object of the invention.
En las figuras 10 y 11 se muestra una segunda realización de la caperuza de la presente invención. Esta segunda realización presenta un sistema de fijación distinto entre el cuerpo inferior -1- y el cuerpo intermedio -2- permitiendo una sujeción más robusta. A second embodiment of the hood of the present invention is shown in Figures 10 and 11.

Tal y como se muestra en las figuras 10 y 11, el cuerpo inferior -1- presenta una banda flexible de encaje -41- que entra en contacto con un saliente -42- del cuerpo intermedio. A su vez, dicho saliente -42- encaja mediante interferencia dimensional con el saliente interno -43- de la pieza inferior. En la figura 11 se muestran la banda flexible de encaje -41- la banda flexible de retención -29- y la banda flexible inferior -12- en sus posiciones desplegadas. Dichas bandas quedan plegadas al encajar los distintos cuerpos -1-, -2-, -3- como se observa en la figura 12 ejerciendo un efecto de retención. As shown in Figures 10 and 11, the lower body -1- has a flexible band of lace -41- that comes into contact with a projection -42- of the intermediate body. In turn, said projection -42- fits by dimensional interference with the internal projection -43- of the lower part.
