Definitions

  • the invention relates to a dispenser for drinkable liquids.
  • a dispenser of the type mentioned at the outset is known from EP 438 451.
  • a housing there is a reservoir for holding the liquid, which can be cooled or heated using suitable means.
  • the reservoir is connected to a filling tube which is arranged in the housing and projects into the interior of a bottle neck when the bottle is placed on the housing with the mouth facing downward.
  • the bottle or the area near the neck is supported on a conical seat of the housing.
  • the bottle has a suitable closure which, when placed on the conical seat is opened automatically.
  • a flap or a breakable membrane or the like inside the bottle neck, which is opened by the filling tube.
  • EP 438 451 it is known to close the mouth of the bottle by a cap which has a hollow cylindrical section protruding into the bottle neck.
  • the hollow cylindrical section is designed to be breakable in its inner region. It is separated by the filling tube, so that the liquid can flow downward into the reservoir of the dispenser by gravity through lateral openings in the filling tube. If the bottle is lifted off, the broken closure element is telescopically moved into the remaining part of the hollow cylindrical section.
  • the reservoir is connected to the atmosphere via an opening in the housing.
  • a filter sits in the opening, which prevents dirt particles from entering the interior of the reservoir through the inflowing air.
  • the inflow of air into the reservoir is necessary so that air can flow in when the bottle is emptied.
  • the invention has for its object to improve a dispenser of the type mentioned in that when a bottle is removed from the conical seat, the connection between the reservoir and the atmosphere is automatically interrupted, so that no contamination from the outside can take place.
  • the hygienic conditions should thus be improved.
  • the upper end section of the filling tube has a valve arrangement with a valve element which is biased by gravity and / or a spring into a closed position in which it closes the opening at the upper end section.
  • the valve element can be from the bottle neck itself, i.e. can be adjusted from its mouth or from a closure element in the bottle neck into the open position.
  • a connection to the reservoir is thus automatically shut off as soon as a bottle is removed, e.g. because it is empty. Dirt particles can therefore no longer get into the reservoir via the fill pipe and contaminate the liquid.
  • the opening in the filling tube is provided on the side at the upper end, and the valve element is a slide guided by the tube, which is connected to an actuating projection located outside the tube.
  • valve element is a sleeve which is displaceable on the outside of the upper end section. Section is arranged and in the closed position bears against a seal on the upper end portion.
  • the seal is, for example, an O-ring seal seated on the filling tube, which at the same time limits the upward movement of the sleeve.
  • a plate connected to the sleeve is preferably provided, against which the mouth of the bottle neck abuts when the bottle is placed on the conical seat. As a result, the sleeve moves into the open position and the liquid can flow from the bottle through the filling tube into the reservoir.
  • the sleeve can be returned to the closed position, for example, by a snap connection being made between the bottle neck and suitable means on the plate, so that when the bottle neck is pulled back, the plate and thus the sleeve are also pulled upward into the closed position. A frictional connection or a snap connection can then ensure that the plate remains in this position.
  • prestress the sleeve or the plate in the direction of the closed position by means of a spring.
  • the plate preferably has a circumferential seal which interacts with a cylindrical cavity below the conical seat which surrounds the upper end section of the filling tube. When a biasing spring is used, the cavity is preferably provided with an upper shoulder or shoulder, against which the plate rests in the closed position of the sleeve.
  • a sealing sleeve can be provided below the actuating plate for the sleeve, which is sealingly connected to the underside of the plate and to the bottom of the cavity, so that the filling tube is sealed below the plate and does not contaminate the Opening in the fill pipe can penetrate into the reservoir.
  • a sleeve closing the opening can also be dispensed with. In the closed position, the plate closes the sleeve from the atmosphere, while the actual sealing takes place through the sleeve. It goes without saying that the cuff must be made of a sufficiently flexible material so that it can yield when the plate is moved into the open position.
  • the valve element is a sleeve which is closed at the upper end and which is telescopically displaceable in the upper end section of the tube.
  • the closed end of the sleeve sealingly cooperates with the upper end of the tube.

  • the sleeve is preferably biased into the closed position by a spring.
  • valve element is actuated by the end of the bottle neck or a configuration of the bottle neck.

As a result, liquid can flow into the pipe via the openings 174, 178 and into the pipe section 160 via the valve seat 164.
  • An air filter 188 is also installed in component 142 in the upper region, so that there is always a connection between the atmosphere and the reservoir 184. This allows air to flow into the volume released in the bottle.

Abstract

Un distributeur de boissons liquides comprend un boîtier dans lequel est situé un réservoir (60) de liquide, de préférence réfrigérable. Le boîtier comprend une surface d'appui (16) conique, ouverte vers le haut, pour soutenir la zone (20) proche du goulot d'une bouteille (64) renversée avec le goulot vers le bas ou similaire. Un tuyau (40) qui pénètre de haut en bas dans le boîtier est connecté au réservoir (60). Une section terminale supérieure du tuyau pourvue d'une ouverture (22) plonge dans le goulot de la bouteille et actionne le cas échéant un élément de fermeture situé dans le goulot de la bouteille afin d'établir une communication fluide entre la bouteille et le réservoir à travers le tuyau. La section terminale supérieure du tuyau comprend un système à clapet (24) avec un clapet maintenu par gravité et/ou par un ressort (44) dans une position de fermeture dans laquelle il ferme l'ouverture de la section terminale supérieure. Le clapet peut être mis dans la position d'ouverture par le goulot de la bouteille ou par un élément de fermeture situé dans le goulot de la bouteille.
