DESCRIPCIONDESCRIPTION
Bomba, particularmente bomba de pulverizacion para la gargantaPump, particularly throat spray pump
La invencion se refiere a una bomba, particularmente a una bomba de pulverizacion para la garganta, con una carcasa, que presenta una abertura de alojamiento con una geometrla de conexion a presion, un elemento de accionamiento, que esta dispuesto en el lado de la carcasa alejado de la abertura de alojamiento, y que durante un accionamiento en una direction de accionamiento puede desplazarse hacia la carcasa, y una boquilla expendedora, que esta dispuesta en un saliente que sobresale transversalmente con respecto a la direccion de accionamiento.The invention relates to a pump, particularly a throat spray pump, with a housing, which has a housing opening with a pressure connection geometry, an actuating element, which is arranged on the side of the housing. away from the housing opening, and that during a drive in a drive direction it can move towards the housing, and a vending nozzle, which is arranged in a projection protruding transversely with respect to the drive direction.
Una bomba de este tipo se conoce por ejemplo, del documento DE 102 00 595 A1.A pump of this type is known, for example, from DE 102 00 595 A1.
Con una bomba de este tipo ha de poder pulverizarse un producto de manera controlada a un determinado lugar. Cuando se trata en el caso del producto, de un medicamento, el cual ha de pulverizarse por ejemplo, en la garganta de una persona, entonces el saliente sirve para acercar la boquilla expendedora lo mas posible a la zona a tratar. Cuando el usuario acciona entonces el elemento de accionamiento, se expende una cantidad dosificada del producto.With such a pump, a product must be sprayed in a controlled manner to a certain place. In the case of the product, of a medicine, which has to be sprayed, for example, in a person's throat, then the projection serves to bring the vending nozzle as close as possible to the area to be treated. When the user then drives the drive element, a dosed quantity of the product is dispensed.
Particularmente en el caso de los medicamentos, es de cierta importancia que estos se protejan frente a una contamination. Por lo tanto, ha de mantenerse cerrado el recipiente en el que esta alojado el medicamento y del cual ha de extraerse el medicamento con la ayuda de la bomba. Debido a este motivo, la carcasa de la bomba se conecta a presion sobre el recipiente, por ejemplo, una botella de vidrio o de material plastico. Debido a ello se une la carcasa de tal manera con el recipiente, que el recipiente en cualquier caso ya no puede ser abierto por el usuario normal.Particularly in the case of medications, it is of some importance that they are protected against contamination. Therefore, the container in which the medicine is housed must be kept closed and from which the medicine must be extracted with the help of the pump. Due to this reason, the pump housing is pressurized on the container, for example, a glass or plastic bottle. Because of this, the housing is connected in such a way with the container, that the container can no longer be opened by the normal user.
Para la conexion a presion se coloca la bomba con la abertura de alojamiento de la carcasa sobre el recipiente. Ha de reunirse entonces una fuerza en parte considerable sobre la bomba, para poder mover la geometrla de la conexion a presion mas alla de una correspondiente geometrla en el recipiente. Las fuerzas necesarias para ello se encuentran absolutamente en varios cientos de Newton.For the pressure connection, the pump is placed with the housing opening of the housing on the vessel. A considerable force must then be gathered on the pump, in order to be able to move the pressure connection geometry beyond a corresponding geometry in the container. The forces necessary for this are found in several hundred Newtons.
Hasta ahora se ha introducido la fuerza necesaria para la conexion a presion a traves del elemento de accionamiento. Esto tiene varias desventajas. Por un lado, el elemento de accionamiento, y con ello la bomba, puede danarse durante la conexion a presion. Por otro lado, es diflcil dosificar exactamente la fuerza necesaria para la conexion a presion, dado que el elemento de accionamiento actua por norma en contra de un resorte.Until now, the force necessary for the pressure connection through the drive element has been introduced. This has several disadvantages. On the one hand, the drive element, and with it the pump, can be damaged during the pressure connection. On the other hand, it is difficult to dose exactly the force necessary for the pressure connection, since the actuator acts as a rule against a spring.
El documento US 2009/0152303 A1 muestra otra bomba con una carcasa, que presenta una abertura de alojamiento con una geometrla de bloqueo, un elemento de accionamiento que esta dispuesto sobre el lado alejado de la abertura de alojamiento, de la carcasa, y puede desplazarse durante el accionamiento en una direccion de accionamiento hacia la carcasa, y una boquilla expendedora, que esta orientada transversalmente con respecto a la direccion de accionamiento. Ademas de ello, hay colocada una caperuza protectora sobre un anillo de fijacion, que rodea la carcasa. La caperuza protectora presenta una pared de tapa alejada de la abertura de alojamiento, que esta unida a una pared lateral, que se alza al menos parcialmente sobre una disposition de superficie en el anillo de fijacion, que se extiende perpendicularmente con respecto a la direccion de accionamiento. Para colocar la bomba sobre un envase, se coloca la bomba provista de la caperuza protectora sobre el envase, de manera que los salientes de la geometrla de bloqueo pueden engancharse detras de un saliente circundante en el envase. Despues de ello, con la ayuda de la caperuza protectora se empuja el anillo de bloqueo sobre el envase, de manera que el faldon, que presenta la geometrla de bloqueo, ya no puede descomprimirse hacia el exterior, y de esta manera la bomba se sujeta de manera fija sobre el envase.Document US 2009/0152303 A1 shows another pump with a housing, which has a housing opening with a locking geometry, a drive element that is arranged on the side away from the housing opening, of the housing, and can move during the drive in a drive direction towards the housing, and a vending nozzle, which is oriented transversely with respect to the drive direction. In addition, a protective cap is placed on a fixing ring, which surrounds the housing. The protective cap has a cover wall away from the housing opening, which is attached to a side wall, which is raised at least partially on a surface arrangement in the fixing ring, which extends perpendicularly with respect to the direction of drive To place the pump on a container, the pump provided with the protective cap is placed on the container, so that the projections of the locking geometry can be engaged behind a surrounding projection in the container. After that, with the help of the protective cap, the locking ring is pushed over the container, so that the skirt, which has the locking geometry, can no longer be decompressed outwards, and in this way the pump is held fixedly on the container.
La invencion se basa en la tarea de poder llevar a cabo el montaje de la bomba en un envase sin influir negativamente en la bomba.The invention is based on the task of being able to carry out the assembly of the pump in a container without negatively influencing the pump.
Esta tarea se soluciona en el caso de una bomba del tipo mencionado inicialmente, debido a que hay colocada una caperuza protectora sobre la carcasa, que presenta una pared de tapa alejada de la abertura de alojamiento, que esta unida a una pared lateral, que se alza al menos parcialmente sobre una disposicion de superficie en la carcasa, que se extiende perpendicularmente con respecto a la direccion de accionamiento, presentando la pared lateral en la zona del saliente una interruption en la direccion perimetral, que llega hasta un extremo de la pared lateral dirigido hacia la carcasa, y estando dimensionada la caperuza protectora para la transmision de fuerzas de conexion a presion.This task is solved in the case of a pump of the type mentioned initially, because a protective cap is placed on the housing, which has a lid wall away from the housing opening, which is attached to a side wall, which is at least partially, it rises on a surface arrangement in the housing, which extends perpendicularly with respect to the direction of operation, the side wall in the area of the projection presenting an interruption in the perimeter direction, which reaches an end of the side wall directed towards the housing, and the protective cap being dimensioned for the transmission of pressure connection forces.
Con una caperuza protectora de este tipo es posible conectar a presion la carcasa sobre el envase, sin cargar por lo demas la bomba. Las fuerzas necesarias para la conexion a presion se transmiten a traves de la caperuza protectora y su pared lateral directamente a la carcasa. Los componentes de la bomba no son solicitados con fuerzas durante la conexion a presion, de manera que queda casi excluido el riesgo de un dano. Las fuerzas, las cuales se necesitan para la conexion a presion, pueden dimensionarse de manera relativamente exacta, de manera que la bomba tambien queda dispuesta de manera fiable sobre el envase y el envase no es danado. Ademas deWith a protective cap of this type it is possible to press the housing on the container under pressure, without otherwise loading the pump. The forces required for the pressure connection are transmitted through the protective cap and its side wall directly to the housing. The pump components are not forcefully requested during the pressure connection, so the risk of damage is almost excluded. The forces, which are needed for the pressure connection, can be sized relatively accurately, so that the pump is also reliably arranged on the container and the package is not damaged.

ello, puede incorporarse ahora en la bomba un cierre de seguridad en union con el elemento de accionamiento, de manera que un usuario puede reconocer, si el envase provisto de la bomba ya ha sido utilizado una vez o no. Debido a la interrupcion, la caperuza protectora puede colocarse sobre la carcasa de la bomba a pesar del saliente, para introducir las fuerzas necesarias para la conexion a presion.in this way, a safety seal can be incorporated in the pump in conjunction with the drive element, so that a user can recognize whether the container provided with the pump has already been used once or not. Due to the interruption, the protective cap can be placed on the pump housing despite the projection, to introduce the necessary forces for the pressure connection.
La pared lateral esta en contacto preferiblemente con la pared perimetral de la carcasa con una tension previa. Tambien puede dejarse la caperuza de protection en la carcasa de la bomba tras el montaje de la bomba. La caperuza de proteccion no sirve por lo tanto solo para el montaje de la bomba en el envase, sino que tambien asume otras funciones protectoras, por ejemplo, durante el transporte del envase.The side wall is preferably in contact with the perimeter wall of the housing with a pre-tension. The protective cap can also be left in the pump housing after pump assembly. The protective cap therefore does not only serve to mount the pump in the container, but also assumes other protective functions, for example, during transport of the container.
La pared perimetral presenta preferiblemente al menos en una section, en la que la pared lateral esta en contacto con ella, la forma de una superficie de revestimiento cillndrica. Esto hace relativamente sencilla la production de la tension previa deseada.The perimeter wall preferably has at least one section, in which the side wall is in contact with it, the shape of a cylindrical coating surface. This makes the production of the desired pre-tension relatively simple.
Se prefiere que la pared lateral rodee la carcasa por al menos 185°, preferiblemente por al menos 210° y de manera particularmente preferida por al menos 240° en direction perimetral. En todos los casos queda asegurado, que puede reunirse en la carcasa la fuerza necesaria para la conexion a presion a traves de la caperuza de proteccion, sin que resulten posiciones inclinadas o similares. Tambien existe suficiente espacio para dejar pasar el saliente a traves de la pared lateral.It is preferred that the side wall surrounds the housing by at least 185 °, preferably by at least 210 ° and particularly preferably by at least 240 ° in the perimeter direction. In all cases, it is ensured that the force necessary for the pressure connection through the protective cap can be assembled in the housing, without resulting in inclined or similar positions. There is also enough space to let the projection pass through the side wall.
La pared de la tapa presenta preferiblemente una prolongation que cubre la interrupcion, que cubre el saliente. De esta manera tambien se protege el saliente mediante la caperuza protectora, y concretamente durante la conexion a presion de la carcasa sobre el envase, como tambien durante un transporte del envase.The wall of the cover preferably has an extension covering the interruption, which covers the projection. In this way, the projection is also protected by the protective cap, and specifically during the pressure connection of the housing on the container, as well as during a transport of the container.
En este caso se prefiere que la prolongacion este provista de un lado frontal acodado, que cubra la boquilla expendedora. De esta manera se mantiene reducido el riesgo de que acceda suciedad desde fuera a la zona de la boquilla. Naturalmente esto no puede excluirse del todo. Debido al recubrimiento se impide no obstante, por ejemplo, la solicitation directa de la boquilla con suciedad, cuando la caperuza protectora esta colocada.In this case it is preferred that the extension is provided with a bent front side, which covers the vending nozzle. In this way the risk of dirt entering from outside the nozzle area is reduced. Naturally this cannot be excluded at all. Due to the coating, however, the direct solicitation of the nozzle with dirt is prevented, for example, when the protective cap is in place.
El lado frontal esta unido preferiblemente mediante paredes de union a la pared lateral. Esto da como resultado una estabilidad mejorada de la caperuza protectora, lo cual se hace notar de manera positiva tanto durante la conexion a presion de la bomba sobre el envase, como tambien durante el transporte posterior.The front side is preferably joined by connecting walls to the side wall. This results in improved stability of the protective cap, which is positively noted both during the pressure connection of the pump on the container, and also during subsequent transport.
La pared lateral presenta de una manera preferida al menos dos zonas de elevation, que estan en contacto con la carcasa a diferentes distancias de la abertura expendedora. Las zonas de elevacion tambien tienen eventualmente diferentes posiciones en direccion radial. De esta manera se amplla la superficie que se encuentra a disposition para la transmision de la fuerza a la carcasa. Cuanto mayor sea la superficie, menor es la tension de presion a introducir por lo demas con condiciones no modificadas, a traves de la caperuza protectora. Esto mantiene reducida la carga de la caperuza.The side wall preferably has at least two elevation zones, which are in contact with the housing at different distances from the vending opening. The elevation zones also eventually have different positions in the radial direction. In this way the surface that is available for the transmission of force to the housing is extended. The larger the surface, the lower the pressure tension to be introduced at least with unmodified conditions, through the protective cap. This keeps the hood load reduced.
Una primera zona de elevacion esta en contacto preferiblemente con una pared anular, la cual rodea el elemento de accionamiento, y una segunda zona de elevacion esta en contacto con una ampliation del diametro de la pared anular. Esta ampliacion del diametro puede formar por ejemplo, un paso desde una primera seccion de carcasa, en la que esta dispuesto el elemento de accionamiento, a una segunda seccion de carcasa, en la que esta configurada la abertura de alojamiento. De esta manera se introduce la fuerza necesaria para la conexion a presion en este tipo de partes de la carcasa, que puede recoger esta fuerza tambien sin mas. La conexion a presion puede producirse debido a ello con una alta fiabilidad.A first elevation zone is preferably in contact with an annular wall, which surrounds the actuating element, and a second elevation zone is in contact with an enlargement of the annular wall diameter. This enlargement of the diameter can form, for example, a passage from a first housing section, in which the drive element is arranged, to a second housing section, in which the housing opening is configured. In this way the necessary force for the pressure connection is introduced in this type of housing parts, which can also collect this force without further ado. The pressure connection can occur because of this with high reliability.
La primera zona de elevacion presenta preferiblemente varias nervaduras dirigidas radialmente hacia el interior distribuidas en direccion perimetral. Pueden proporcionarse por ejemplo, cinco nervaduras distribuidas en direccion perimetral. Las nervaduras no solo transmiten la fuerza necesaria para la conexion a presion de la carcasa a la carcasa, sino que tambien rigidizan la pared lateral, de manera que la pared lateral misma tambien puede transmitir fuerzas mayores.The first elevation zone preferably has several ribs directed radially inwardly distributed in the perimeter direction. For example, five ribs distributed in the perimeter direction can be provided. The ribs not only transmit the force necessary for the pressure connection of the housing to the housing, but also stiffen the side wall, so that the side wall itself can also transmit greater forces.
En este caso se prefiere que las nervaduras presenten en la direccion perimetral y/o en la direccion radial, un grosor que sea mayor que el grosor de la pared lateral en direccion radial. De esta manera puede configurarse la caperuza protectora en general con una masa relativamente pequena, ya que la pared lateral puede mantenerse relativamente delgada. Esto por un lado ahorra costes y facilita por otro lado el manejo.In this case it is preferred that the ribs present in the perimeter direction and / or in the radial direction, a thickness that is greater than the thickness of the side wall in the radial direction. In this way the protective cap can be configured in general with a relatively small mass, since the side wall can be kept relatively thin. This on the one hand saves costs and facilitates on the other hand the handling.
Preferiblemente al menos una nervadura presenta una distancia con respecto a la interrupcion, que es menor que el grosor de la nervadura en direccion perimetral. De esta manera, una nervadura esta por lo tanto directamente al lado de la interrupcion, de manera que la pared lateral presenta directamente junto a la interrupcion una rigidez mejorada y tambien puede transmitir aqul correspondientes fuerzas. Preferiblemente hay dispuestas correspondientes nervaduras incluso a ambos lados de la interrupcion.Preferably at least one rib has a distance from the interruption, which is less than the thickness of the rib in the perimeter direction. In this way, a rib is therefore directly next to the interruption, so that the side wall has an improved rigidity directly next to the interruption and can also transmit corresponding forces. Preferably corresponding ribs are arranged even on both sides of the interruption.
Las nervaduras estan unidas preferiblemente a la pared de la tapa. Resulta de esta manera una introduction deThe ribs are preferably attached to the wall of the lid. This results in an introduction of

fuerza directa a traves de la pared de la tapa a las nervaduras, de manera que pueden transmitirse aqul fuerzas lo suficientemente grandes.direct force through the wall of the lid to the ribs, so that forces large enough can be transmitted.
Tambien es ventajoso cuando las nervaduras estan en contacto con el elemento de accionamiento radialmente por el exterior. Debido a ello la caperuza protectora se gula aun mejor por la carcasa. No se relaciona con ello una influencia negativa en la bomba, dado que no actuan sobre el elemento de accionamiento fuerzas actuantes en la direccion de accionamiento. La caperuza protectora se sujeta no obstante, tras el montaje de la bomba en el envase, mejor sobre la carcasa.It is also advantageous when the ribs are in contact with the drive element radially from the outside. Because of this, the protective cap glides even better through the housing. A negative influence on the pump is not related to this, since no forces acting on the driving direction do not act on the drive element. The protective cap is held, however, after mounting the pump in the container, better on the housing.

la caperuza protectora en representacion en perspectiva.the protective cap in perspective representation.
Una bomba 1 representada en la Fig. 1, que esta configurada como bomba de pulverization para la garganta, esta conectada a presion sobre un envase 2. El envase 2 esta configurado por ejemplo, como botella de vidrio o de material plastico y presenta un espacio de almacenamiento 3, en el que hay dispuesto (no representado) un medicamento para el tratamiento de molestias en una garganta de una persona.A pump 1 shown in Fig. 1, which is configured as a throat spray pump, is connected to a pressure on a container 2. The container 2 is configured, for example, as a glass or plastic bottle and has a space of storage 3, in which there is arranged (not shown) a medicament for the treatment of discomfort in a person's throat.
La bomba 1 presenta una carcasa 4 con una abertura receptora 5, en la que se coloca un cuello 6 del envase 2. Para sujetar la carcasa 4 en el cuello, la abertura receptora 5 esta provista de una geometrla de conexion a presion 7, por ejemplo, un saliente circundante saliente radialmente hacia el interior. El cuello 6 esta provisto de un correspondiente saliente contrario 8. Para fijar la carcasa 4 sobre el envase 2, la carcasa 4 con la abertura receptora 5 primeramente tiene que colocarse en el cuello 6. Despues de ello, ha de ejercerse una fuerza sobre la carcasa en direccion del envase 2, la cual es tan grande, que la carcasa 4, al menos en la zona, en la que esta dispuesta la geometrla de conexion a presion 7, se ensancha de tal manera, que la geometrla de conexion a presion 7 puede deslizarse mas alla del saliente contrario 8. Debido a la elasticidad de la carcasa 4, la geometrla de conexion a presion 7 se engancha detras del saliente contrario 8. Las fuerzas necesarias para este tipo de fijacion, que tambien se denominan como “fuerzas de conexion a presion”, se encuentran absolutamente en el rango de varios cientos de N. Las fuerzas de conexion a presion se encuentran en el presente caso en el orden de magnitud de 400 N.The pump 1 has a housing 4 with a receiving opening 5, in which a neck 6 of the container 2 is placed. To hold the housing 4 on the neck, the receiving opening 5 is provided with a pressure connection geometry 7, by example, a surrounding projection radially inwardly protruding. The neck 6 is provided with a corresponding opposite projection 8. To fix the housing 4 on the container 2, the housing 4 with the receiving opening 5 must first be placed on the neck 6. After that, a force must be exerted on the housing in the direction of the container 2, which is so large, that the housing 4, at least in the area, in which the pressure connection geometry 7 is arranged, widens in such a way that the pressure connection geometry 7 can slide beyond the opposite projection 8. Due to the elasticity of the housing 4, the pressure connection geometry 7 engages behind the opposite projection 8. The forces necessary for this type of fixing, which are also referred to as "forces of pressure connection ”, are absolutely in the range of several hundred N. The pressure connection forces are in the present case in the order of magnitude of 400 N.
La bomba 1 presenta un elemento de accionamiento 9, que puede desplazarse en contra de la fuerza de un resorteThe pump 1 has a drive element 9, which can move against the force of a spring
10, en el caso de un accionamiento, en una direccion de accionamiento (flecha 18) hacia el interior de la carcasa 4. El elemento de accionamiento 9 se sujeta en este caso en la carcasa 4 mediante un aseguramiento contra la calda10, in the case of an actuation, in an actuation direction (arrow 18) towards the inside of the housing 4. The actuation element 9 is then held in the housing 4 by means of a clamp against the broth
11. En el caso del accionamiento, el elemento de accionamiento 9, reduce con un empujador 12 un espacio de bomba 13, que esta configurado entre el empujador 12 y una carcasa auxiliar 14. El espacio de bomba 13 esta cerrado mediante una valvula antirretorno con un elemento de valvula 15 hacia el espacio de almacenamiento 3. Cuando se reduce el espacio de bomba 13, entonces se expulsa un llquido que se encuentra dentro a traves de una boquilla 16, que esta configurada en un saliente 17, que se extiende transversalmente con respecto a una direccion de accionamiento 18. La boquilla 16 esta unida al espacio de bomba 13 a traves de canales 19. Cuando se libera el elemento de accionamiento 9, entonces es empujado nuevamente hacia el exterior debido a la fuerza del resorte 10, de manera que aumenta el espacio de bomba 13 y en este caso succiona a traves de la valvula antirretorno con el elemento de valvula 15, llquido del espacio de almacenamiento 3.11. In the case of the drive, the drive element 9, reduces with a pusher 12 a pump space 13, which is configured between the pusher 12 and an auxiliary housing 14. The pump space 13 is closed by a non-return valve with a valve element 15 towards the storage space 3. When the pump space 13 is reduced, then a liquid that is inside is ejected through a nozzle 16, which is configured in a projection 17, which extends transversely with with respect to an actuation direction 18. The nozzle 16 is connected to the pump space 13 through channels 19. When the actuation element 9 is released, it is then pushed back outwards due to the force of the spring 10, so which increases the pump space 13 and in this case sucks through the non-return valve with the valve element 15, liquid from the storage space 3.
La funcion de una valvula de este tipo es conocida en si y se describe en el documento mencionado inicialmente DE 102 00 595 A1.The function of such a valve is known per se and is described in the document initially mentioned DE 102 00 595 A1.
Las fuerzas necesarias para la conexion a presion de la carcasa 4 sobre el envase 2, han sido introducidas hasta ahora a traves del elemento de accionamiento 9. Esto ha resultado ser desventajoso.The forces necessary for the pressure connection of the housing 4 on the container 2 have been introduced so far through the drive element 9. This has proved to be disadvantageous.
Para poder introducir en la carcasa 4 estas fuerzas, las cuales han de actuar en la direccion de accionamiento 18, se proporciona ahora una caperuza protectora 20, que esta colocada sobre la carcasa 4. La carcasa 4 presenta una primera section 21 en forma de cilindro, en la que esta dispuesto el elemento de accionamiento 9, y una segunda section 22 tambien configurada en forma de cilindro, en la que esta configurada la abertura receptora 5. Entre las dos secciones 21, 22 hay configurada una ampliation del diametro 23. La ampliation del diametro 23 forma aqul enIn order to be able to introduce these forces into the housing 4, which must act in the driving direction 18, a protective cap 20 is now provided, which is placed on the housing 4. The housing 4 has a first section 21 in the form of a cylinder , in which the drive element 9 is arranged, and a second section 22 also configured in the form of a cylinder, in which the receiving opening 5 is configured.

el lado dirigido hacia la caperuza protectora 20, una disposicion de superficie 24, sobre la cual se alza la caperuza protectora 20 con una pared lateral 25. La pared lateral 25 de la caperuza protectora 20 esta unida por su parte a una pared de tapa 26. Cuando se ejerce una fuerza sobre la pared de la tapa 26 en direction de accionamiento 18, entonces se introduce esta fuerza a traves de la pared lateral 25 en la carcasa 24. La pared lateral 25 esta dimensionada en este caso de tal manera, que puede transmitir las fuerzas de conexion a presion necesarias. Debe presentar por lo tanto una determinada rigidez, para evitar una abolladura. La magnitud de las fuerzas de conexion a presion se gula por determinados criterios, por ejemplo, la configuration de la geometrla de la conexion a presion o el tamano de la bomba. Las fuerzas de conexion a presion pueden determinarse no obstante, facilmente y de manera correspondiente puede dimensionarse la caperuza protectora 20.the side directed towards the protective cap 20, a surface arrangement 24, on which the protective cap 20 is raised with a side wall 25. The side wall 25 of the protective cap 20 is joined in turn to a cover wall 26 When a force is exerted on the wall of the cover 26 in the direction of operation 18, then this force is introduced through the side wall 25 into the housing 24. The side wall 25 is sized in this case in such a way that It can transmit the necessary pressure connection forces. It must therefore have a certain stiffness, to avoid a dent. The magnitude of the pressure connection forces is regulated by certain criteria, for example, the configuration of the pressure connection geometry or the size of the pump. The pressure connection forces can, however, be determined easily and correspondingly, the protective cap 20 can be sized.
La pared lateral 25 esta en contacto con la pared perimetral de la primera section 21 con una determinada tension previa, es decir, se necesita tambien una pequena fuerza, para poder retirar la caperuza protectora 20 de la carcasa 4. La caperuza protectora 20 puede servir entonces tambien como protection durante un transporte o entre dos manejos de la bomba 1.The side wall 25 is in contact with the perimeter wall of the first section 21 with a certain pre-tension, that is, a small force is also needed, in order to remove the protective cap 20 from the housing 4. The protective cap 20 can serve then also as protection during transport or between two pump 1 handles.
La pared de la tapa 26 presenta una prolongation 27, que cubre el saliente 17. La prolongation 27 presenta un lado frontal acodado 28 hacia abajo, que cubre la boquilla 16. El lado frontal 28 esta unido a la pared lateral 25 a traves de paredes de conexion 29 (solo se representa una) con la pared lateral 25.The wall of the cover 26 has an extension 27, which covers the projection 17. The extension 27 has a front side angled 28 downwards, which covers the nozzle 16. The front side 28 is connected to the side wall 25 through walls connection 29 (only one shown) with side wall 25.
De la pared lateral 25 se reconoce una seccion 30, que se gula alrededor de la primera seccion 21 de la carcasa 4. La pared lateral no se gula en este caso por la totalidad del perlmetro de la primera seccion 21 de la carcasa 4, sino que presenta una interruption, a traves de la cual se gula el saliente 17. Esta interruption se describe en relation con un segundo ejemplo de realization de la caperuza protectora en relacion con las Figs. 3 a 6.From the side wall 25 a section 30 is recognized, which is rotated around the first section 21 of the housing 4. In this case the side wall is not glided by the entire perimeter of the first section 21 of the housing 4, but which presents an interruption, through which the projection 17 is gula. This interruption is described in relation to a second example of realization of the protective cap in relation to Figs. 3 to 6
La pared lateral 25 se extiende en todo caso al menos por 185° de la carcasa 4 en direccion perimetral. La pared lateral 25 se extiende preferiblemente por al menos 210° o incluso por al menos 240° en direccion perimetral. Esto asegura que la pared lateral es capaz de transmitir las fuerzas necesarias para la conexion a presion de la carcasa 4 sobre el envase 2, tambien en una medida suficiente de manera distribuida en direccion perimetral.The side wall 25 extends in any case at least 185 ° of the housing 4 in the perimeter direction. The side wall 25 preferably extends by at least 210 ° or even at least 240 ° in the perimeter direction. This ensures that the side wall is capable of transmitting the forces necessary for the pressure connection of the housing 4 on the container 2, also to a sufficient extent distributed in a perimeter direction.
La Fig. 2 muestra un ejemplo de realizacion modificado, en el que los mismos elementos estan provistos de las mismas referencias que en la Fig. 1. Ha cambiado la caperuza protectora 20.Fig. 2 shows a modified embodiment example, in which the same elements are provided with the same references as in Fig. 1. The protective cap 20 has changed.
La caperuza protectora 20 presenta distribuidas en direccion perimetral varias nervaduras 31 que se extienden radialmente hacia el interior, que estan unidas a la pared lateral 25 y con la pared de la tapa 26 y configuradas preferiblemente de una pieza con ellas. Las nervaduras 31 se alzan con una zona de elevation 32 sobre un lado de la primera seccion 21 de la carcasa 4 alejado de la abertura receptora 5. De esta manera, la caperuza protectora 20 presenta ahora dos zonas de elevacion, que estan en contacto a diferentes distancias de la abertura expendedora 5 con la carcasa 4. Una zona de elevacion 32 se alza, como se ha mencionado, sobre el lado frontal de la primera seccion 21 de la carcasa 4. La otra zona de elevacion se alza sobre la ampliation del diametro 23 de la carcasa 4, como tambien en la forma de realizacion segun la Fig. 1.The protective cap 20 has several ribs 31 distributed in a perimeter direction that extend radially inwardly, which are connected to the side wall 25 and with the wall of the cover 26 and preferably configured in one piece with them. The ribs 31 are raised with an elevation zone 32 on one side of the first section 21 of the housing 4 away from the receiving opening 5. In this way, the protective cap 20 now has two elevation zones, which are in contact with different distances from the vending opening 5 with the housing 4. An elevation zone 32 is raised, as mentioned, on the front side of the first section 21 of the housing 4. The other elevation zone is raised on the extension of the diameter 23 of the housing 4, as well as in the embodiment according to Fig. 1.
Como puede verse en la Fig. 3, se proporcionan en total cinco nervaduras 31. Las nervaduras 31 estan dispuestas, como se ha mencionado, radialmente hacia el interior desde la pared lateral 25. Las nervaduras 31 tienen en direccion radial y perimetral un grosor, que es mayor que el grosor de la pared lateral 25 en direccion radial. En muchos casos sera suficiente no obstante, cuando las nervaduras 31 presenten solo en direccion perimetral o solo en direccion radial un grosor mayor que el grosor radial de la pared lateral 25. Las nervaduras 31 tienen dos tareas. Sirven por una parte para la transmision de fuerza de la pared de la tapa 26 a la carcasa 4. Por otro lado, tambien rigidizan la pared lateral 25, de manera que la pared lateral 25 puede transmitir fuerzas mayores.As can be seen in Fig. 3, a total of five ribs 31 are provided. The ribs 31 are arranged, as mentioned, radially inwards from the side wall 25. The ribs 31 have a thickness in the radial and perimetral direction, which is greater than the thickness of the side wall 25 in the radial direction. In many cases it will be sufficient, however, when the ribs 31 have only a perimeter direction or only in a radial direction a thickness greater than the radial thickness of the side wall 25. The ribs 31 have two tasks. They serve on the one hand for the transmission of force from the wall of the cover 26 to the housing 4. On the other hand, they also stiffen the side wall 25, so that the side wall 25 can transmit greater forces.
Como se ha mencionado anteriormente, la pared lateral 25 presenta una interrupcion 33, que se extiende desde la pared de la tapa 26 hasta el extremo de la caperuza protectora 20 dirigido hacia la carcasa 4. De esta manera es posible colocar la caperuza protectora 20 sobre la bomba 1 a pesar de la existencia del saliente 17.As mentioned above, the side wall 25 has an interruption 33, which extends from the wall of the cover 26 to the end of the protective cap 20 directed towards the housing 4. In this way it is possible to place the protective cap 20 on the pump 1 despite the existence of the projection 17.
Hay dispuestas dos nervaduras 31a, 31b, al lado de la interrupcion 23. Su distancia desde la interrupcion 23 es menor que su grosor en direccion perimetral. Correspondientemente se rigidiza aqul la pared lateral 25 directamente junto a la interrupcion 23, de manera que tambien es posible aqul una transmision de fuerza suficiente.Two ribs 31a, 31b are arranged, next to the interruption 23. Its distance from the interruption 23 is less than its thickness in the perimeter direction. Correspondingly, the side wall 25 is stiffened directly next to the interruption 23, so that a transmission of sufficient force is also possible.
Como puede verse particularmente tambien en la Fig. 2, las nervaduras 31 estan en contacto con el elemento de accionamiento radialmente desde el exterior o solo tienen una pequena holgura con respecto al elemento de accionamiento 9. Debido a ello se estabiliza el elemento de accionamiento 9 durante un transporte de la bomba 1.As can also be seen in Fig. 2, the ribs 31 are in contact with the drive element radially from the outside or only have a small clearance with respect to the drive element 9. Due to this the drive element 9 is stabilized during a transport of the pump 1.
