Abstract

A device for reducing the germ population on taps used for dispensing drinks such as beer or non-alcoholic drinks, comprises a container vessel (1) filled with a disinfecting agent (3) consisting of non-denatured ethyl alcohol having a concentration of at least 60 vol. % alcohol, into which the delivery pipe (4) of the drink dispensing tap is inserted. The vessel (1) is preferably of glass or transparent plastic to allow visual inspection of the alcohol (3), which can be replaced if it becomes contaminated with the beer etc. dispensed from the tap. Preferably the container (1) is sealed by a rubber bung (2) which is drilled with a hole (5) of such dimensions that the device can be pushed onto the delivery pipe (4) and will be held in place by friction. The bung (2) carries an air vent (6) to allow the vessel (1) to be completely filled with the alcohol disinfectant (3).

Description

The invention relates to a device reduction the number of bacteria in dispensing systems for beverages, in particular of beer and soft drinks dispensers where in the device has a vessel which Mouthpiece of the tap includes.

The problem with such dispensing systems is that that this with little use with a longer service life tend to be in the area of air-contacting beverages The tap taps run through the surrounding area existing various microorganisms, fruit flies, To germinate flies etc. Headlines in the day press of the year 1995 about poor hygiene in Dispensing systems not only led to consumers, son also unsettling in the catering trade. Patho gene germs could not be detected, ever however, indicator germs such as E. coli and coliforms have been Germs, found to detect pathogenic germs serve, as well as increased aerobic bacterial counts. Due to the The fact that the beers tend to hy breweries  gienisch perfect and a microbial loading load only takes place through the dispensing system from the state medical food and veterinary Central Hesse Investigation Office, casting the proposal according to table 1 for assessing the hygiene status makes (see BRAUWELT, 1936, No. 21/22, pp. 1014-1016).

Table 1

From US 1 850 359 is a beverage tap known, where a pan bar container is pushed over the mouthpiece to prevent the ingress of dust, dirt etc. However, this known device is not suitable for Prevent germ growth.

The invention has for its object a Vorrich to propose a system that allows simple and way the formation of Effectively prevent germs.

This object is achieved with the features of claim 1 solved.

According to the invention, a tap is on each tap plant a vessel pushed on, which is a disinfectant contains medium from non-denatured ethyl alcohol, so that  the inside of the tap is removed from the ambient air is closed. The ethyl alcohol in the jar, which is undenatured and has an alcohol concentration of has at least 60 vol.%, continues to work germicidal and prevents the multiplication of germs. Measurements have shown that the requirements Table 1 can be reached and in the case of aerobic germ number is clearly undercut after 14 days, d. H. only 4 germs were detected (Table 2).

Table 2

It is assumed that the entire dispensing system here a thorough mechanical cleaning in min at least every 14 days in accordance with the Ordinance on Ge drinking machine is subjected.

In an advantageous embodiment of the device according to the invention the container made of a transparent plastic or glass, which is advantageous with a rubber stopper is closed, the opening for pushing through of the lower end of the tap. The diameter The opening in the rubber stopper is chosen so that the vessel on the tap is held by friction alone is. In this way it is possible to short the tap to be sealed against germs in good time or how the open. A venting cannula is advantageous provided as available in medical stores is. The simplicity of use and the possibility the observation of ethyl alcohol within the Vessel makes it possible to get aerobic germs and indicators avoid germs as much as possible.

In the embodiment shown in the drawing, one end of a tap 4 can be seen, over which a vessel 1 is pushed from a plastic, which is closed by a rubber stopper 2 . This rubber stopper 2 is fixed on the one hand with relatively large friction on the vessel 1 , so that the vessel 1 hangs on the rubber stopper 2 , on the other hand, the bore 5 in the rubber stopper 2 is selected so that a sufficiently large friction between stopper 2 and tap 4 is given , so that the vessel 1 is held as such on the tap 4 . For complete filling of the vessel 1 with ethyl alcohol 3 , a vent 6 is inserted into the rubber stopper 2 . Inside the vessel 1 is an ethyl alcohol 3 with a concentration greater than 60 vol.% Alcohol. If larger contaminations with beer occur here, this can be observed from the outside, so that an exchange of the ethyl alcohol 3 can take place quickly.
