Definitions

• the invention relates to a locking device for a
• Dispensing systems have a manually or automatically operated metering and closing valve, which determines the amount of beverage served.
• vermin such as small mosquitoes
• a disadvantage of conventional dispensing systems is that vermin, such as small mosquitoes, are attracted by the beverage drops adhering to the mouth of the tap, particularly in the warm season, and crawl into the tap. During the next dosing process, these mosquitoes are then washed out with the drink and are then in the container holding the drink, which often leads to complaints from guests due to poor hygiene.
• No. 3,885,711 shows a device for metering liquids, in which a closing device is provided in the mouth area, in which a closing flap is pivotally mounted on a tap.
• the flap is preloaded into its closed position via spring preload.
• DE-PS-1 187 148 discloses a lamellar closure which is brought into an open position by the liquid jet.
• Such a closing device has an extremely complex structure and there is also the risk that even the slightest contamination will not make it possible to close the tap tightly.
• Furthermore, such a device makes it very difficult to dispense small amounts of liquid, since a minimum liquid pressure is required in order to bring the closing slats into their open position.
• Another disadvantage of this Known solution can be seen in the fact that the slats always protrude into the liquid flow, so that, for example, there is considerable foaming when pouring beer.
• the invention has for its object to provide a locking device that ensures proper closing with a simple structure.
• a type of closing valve is assigned to the tap, via which the mouth area is closed in such a way that the entry of vermin or other contamination in the periods between two pouring operations is practically impossible.
• This closing valve is designed such that the interior of the tap can be virtually completely shut off from the environment. Upstream of this closing valve, the metering and closing valve that is usually used is provided in the tap, which is only intended for beverage metering - but this is not suitable for preventing the occurrence of flies etc.
• the closing device has a closing body which is prestressed into its closed position which closes off the mouth region and which can be brought into its open position by hand or by the beverage jet. This closing body is pivoted.
• the closing body has a stop lever which is pivoted when positioning a glass with respect to the tap and thus leads to the opening of the closing body. According to the invention, the closing body is reset so that tight closing is ensured with a simple structure.
• the tap can be provided with a closing device ex works, but it is preferred to design this closing device as a retrofit part.
• the retrofittable locking device preferably has a plug-in sleeve which is, for example, attached to the tap as a slotted sleeve.
• the construction of the locking device is particularly simple if a joint projection is formed in the area of the locking body, which is articulated on the plug-in sleeve. This variant ensures that the closing body can be pivoted away from the tap at a sufficient distance, so that the glass is correspondingly easy to attach.
• Figure 1 is a schematic representation of a tap, which is provided with a closing device according to the invention.
• FIG. 2 shows a schematic diagram of a first exemplary embodiment of a closing device for a tap according to FIG. 1.
• FIG. 1 shows a greatly simplified representation of a tap 1.
• This has a connector 2 for flange mounting on a beverage line.
• the beverage is dosed via a dosing and shut-off valve 4 indicated by dashed lines, which in the exemplary embodiment shown can be actuated by means of a pivotable hand lever 6.
• a closing device 10 is fastened, via which the mouth area of the tap 1 can be closed between two pouring operations in such a way that the entry of mosquitoes or other vermin into the interior of the tap 1 is prevented.
• the closing device 10 is designed such that it is automatically brought into an open position, for example by the impulse of the emerging beverage jet or when a glass is attached or - in the case of more complex solutions - so that the beverage can flow out essentially without pressure loss and deflection. As soon as the pouring process is finished, the mouth is reliably closed to improve hygiene.
• a side effect associated with this invention is that the closing device 10 prevents the beverage from dripping.
• the locking device 10 is designed as a retrofit part that is plugged onto conventional taps. In principle, it is also possible to integrate this closing device 10 into the tap 1 by the manufacturer.
• FIG. 2 shows a preferred embodiment in which the closing device 10 is actuated through a glass into which the drink is to be filled.
• This locking device 10 has a plug-in sleeve 12 which engages around the mouthpiece 8 of the tap 1.
• the receptacle 12 is clamped or screwed onto the mouth piece 8.
• the receptacle 12 carries a plate-shaped closing body 14 which seals the outlet cross section.
• the closing body 14 has an articulated projection 16 on the top, which is articulated on one or more swivel cheeks 18 of the plug-in sleeve 12 via a swivel axis, not shown.
• the joint projection 16 can for example be between two Immerse neighboring swivel cheeks 18 or grasp a single swivel cheek in a U-shape.
• the closing body 14 is extended beyond the joint projection 16. This extended part forms a balance weight 20, which is selected so that the closing body 14 acts on its closing position.
• the closing body 14 swivels approximately into a vertical position and then extends at a distance from the tap which is determined by the length of the joint projection 16 and the swivel cheek 18.
• Joint projection 16 or the counterweight 20 abuts. This prevents the tap from dipping into the drink, so that
• the closing body 14 is opened by means of a stop leg 22 formed thereon, which extends obliquely or in an arc shape downwards in the illustration according to FIG.
• a stop leg 22 formed thereon, which extends obliquely or in an arc shape downwards in the illustration according to FIG.
• the weight and the lever arm of the balance weight 20 must be selected so that the effective torque is greater than the torque applied by the weight of the closing body 14, which acts in the opposite direction.
• This construction has an extremely simple construction and the particular advantage that the opening cross section of the tap 1 is only released when a glass is attached.
• the closing body 14 is pivotally mounted. In principle, it is also possible to use the
• Lead closing body axially adjustable in the socket 12, so that this is moved up (or down) when attaching a glass and releases the mouth cross-section.
• a carrier 24 for advertising can be attached to the stop leg 22 or to the counterweight the advertising is printed directly, a corresponding printing area should be provided.
• a closing device for a tap of a dispensing system via which the opening cross section of the tap can be closed in order to prevent vermin, for example flies, etc., from entering.
