Definitions

• the invention relates to a container for cooled storing of drinks, for instance beer.
• Such containers are generally known, for example in the form of large containers used in catering establish- ments with a capacity in the order of magnitude of 1,000 litres, wherein at least a part of the walls of the con ⁇ tainer takes a double-walled form and wherein a coolant flows in the spaces enclosed by the double-walled parts.
• This coolant can for instance be formed by water but it is equally possible to use another liquid, for instance glycol or a mixture of water and glycol. In such a case this coolant is usually supplied from a separate cooling apparatus.
• cooling apparatus which are formed by a cooled housing in which beer canisters are placed. This is likewise the case for instance in catering es ⁇ tablishments with the 50-litre canisters typical therein.
• the canister wall which is usually manufactured from metal, is per se sufficiently heat-conducting, although the drink, in this case beer, is generally considerably less heat-conducting so that, when a canister coming from outside is placed in such a refrigerator, it takes a long time before the beer pre ⁇ sent in the interior of the canister is fully cooled. It must be noted herein that the beer canister is at rest so that no forced flows occur in the beer.
• the container according to the invention is provided with cooling means extending into the interior of the container.
• the entire content of the container is located a short distance from the cooling means so that the cooling means are used effectively and the whole content of the container can be cooled within a comparatively short period.
• An additional advantage is that temperature gradients hardly occur inside the beer. The temperature of the beer is thus everywhere equally low in the whole container so that the danger of secon ⁇ dary fermentation and occurrence of spoiling in other manner are prevented.
• the invention is for instance likewise applicable to the 10-litre canisters of beer often used in a "home tap". These containers are not generally provided with cooling means. It is customary to store such containers in a cold place, for instance in the domestic refrigera ⁇ tor. In many situations this is less attractive; on an occasion when a home tap is used the domestic refrigera ⁇ tor is usually filled with other articles.
• the invention is otherwise applicable to containers suitable for stor ⁇ ing drinks other than beer, for example soft drinks, mineral water, fruit juice or white wine. By likewise providing such a container with cooling means arranged in the interior these drawbacks can be obviated.
• the cooling means are formed by a conduit which extends through the con- tainer and which extends through all areas of the inte ⁇ rior of the container.
• the cooling means are formed by a cooling spiral arranged in the interior of the container and provided with feed and drain con ⁇ duits carried through the container wall.
• fig. 1 shows a schematic sectional view of a first embodiment of the invention
• fig. 2 shows a side view of the device depicted in fig. 1
• fig. 3 is a sectional view of a second embodiment of the device according to the invention
• fig. 4 is a sectional view of a second embodiment of the invention.
• the container 1 shown in fig. 1 is formed by a con- tainer wall 2 which is provided on its outside with an insulating layer 3.
• the container wall 2 supports by means of supports 4 on the ground.
• a cover 5 is arranged on one side of the container in which a drain conduit 6 is arranged by means of a bush, as is a feed conduit 7 for supplying compressed air or oxygen.
• Cover 5 takes a removable form so that access can be acquired to the interior of the container, for instance for cleaning operations.
• a cooling spiral 8 Arranged in the container is a cooling spiral 8 which is manufactured from zinc-plated copper, stainless steel or aluminium.
• the feed and drain pipes 9, 10 are formed through the container wall 2 outward of the cover 5.
• the cooling spiral 8 is thus arranged fixedly in con ⁇ tainer 1.
• the cooling spiral rests by means of supports 11 against the inside of the container.
• the diameter of the spiral is chosen such that no single point in the interior of the container is located a great distance from the cooling spiral. According to a preferred embodi ⁇ ment the diameter of the cooling spiral amounts to sligh- tly more than half the internal diameter of the con ⁇ tainer.
• a cooling medium is supplied to the cooling spiral or drai ⁇ ned therefrom.
• cooling medium in such a stationary beer container use can be made of for instance glycol which is cooled by means of a separate cooling apparatus not shown in the drawings.
• a cooling apparatus comprises a compressor, a throttle valve and a condenser in addition to associated control valves.
• Such a cooling apparatus will of course likewise comprise a thermostat with which it is possible to keep the temperature of the beer inside the container constant within narrow limits.
• the embodiment shown in fig. 3 relates to a movable beer container; for instance in the form of a 10-litre canister often used on occasions when a home tap is used.
• a beer container 12 is formed by a container wall 13 on the outside of which is arranged insulation material 14.
• a connecting device 15 onto which the home tap can be connected.
• This home tap does not form the subject of this patent application so that neither this nor the construction of the connecting point will be elucidated further.
• a cooling spiral 8 which is carried through the top part of the container wall 13 with the feed and drain conduits 9, 10. These feed and drain conduits are provided with connections with which it is possible to cause mains water to flow through the cooling spiral. In view of the temperature of this mains water it is possible to at least partially cool the beer herewith. In some situations it will be desirable to apply an additional cooling, for which pur ⁇ pose use can once again be made of for instance glycol cooling.
• a con ⁇ tainer 15 is shown that is formed by a metal container wall 16 around which is arranged an insulating wall 17.
• a recess which can be closed by means of a cover 18.
• the cover 18 can be fixed on the container wall 16 so that the container 15 is closed.
• a tap tube 19 which extends to the bottom of the container 15.
• the tap tube 19 is provided with unspecified connecting means 20 with which the tap tube can be connected onto a tap device.
• a connection (not shown) for feeding gas, for instance carbon dioxide, to the container.
• a cooling jacket 21 is arranged round the tap tube.
• This cooling jacket is provided with a connec ⁇ ting piece 22, while the bottom connects onto a tube 23 which also extends through cover 18.
• a flow of a cooling medium for instance water, can be applied in the jacket 21.
• this embodiment has the advantage that it can be manufactured more easily; all the cooling-specific com ⁇ ponents are connected to the cover.
• a cool ⁇ ing spiral can be arranged round tap tube 19 instead of a cooling jacket.
• the medium flowing out of the container through the tap tube is in the first instance cooled, in view of the fact that the liquid comes into contact with the outside environment for the first time only when it moves out of the container, the danger of spoiling is limited before this time; of course the cooling jacket likewise has a cooling effect on the beer located in the vicinity; an excellent solution is obtained when a cooling spiral is arranged in the vicini ⁇ ty of the tap tube; this can be embodied making contact with the tap tube, but can also be arranged in the vici ⁇ nity thereof without making contact therewith. In both cases a better cooling will still be obtained than when cooling takes place from outside. It is of course pos ⁇ sible to apply a specific cooling of the tap tube as well as cooling by means of a separate cooling spiral; even with different cooling media.
