Definitions
- the invention relates to a container with at least one vacuum chamber with a Access opening, in particular beverage container with a vacuum chamber having self-cooling device such as beer keg or the like, which access opening closed by a closure means after the generation of the vacuum is.
- Form of a self-cooling beer keg is e.g. from EP 1 054 222.
- several chambers are present, namely on the one hand a bubble to hold the drink, a chamber that encloses the bubble and forming an evaporator space, and one enclosing these two chambers third chamber forming an absorber space in which an absorber material, in particular zeolite granules is arranged.
- the evaporator room and the absorber room are via a partition, in which a valve device is arranged, separated from each other. Water is used as evaporator material.
- the absorber space is first with the help of a Heating step evacuated and dried.
- the contained in the absorber room Zeolite granules are brought back to ambient temperature before the drink is filled into the bladder, or while it is already in the bladder. Is now opened before tapping the valve device and thus the evacuated Absorber space connected to the evaporator room, steam flows from the evaporator room into the absorber room. So it finds an evaporation process instead, which requires heat, which in turn withdrawn from the drink becomes, which thereby cools. This evaporation and absorption runs for so long until the crystalline zeolite is saturated with water or the valve is closed and the Wasserdampfionattritt is interrupted.
- the valve arranged in the partition wall can be moved from the outside by a suitable movement mechanism be operated with an opening lever or the like.
- Such a beverage container is a reusable container, that is, there is the Possibility to regenerate the self-cooling device and after filling the bladder to start up again.
- Decisive for the function of the self-cooling device is the vacuum in the vacuum chamber of the self-cooling device. This must be maintained for a long time to the reversible evaporation mode to ensure and thus the multiple usability of Container.
- the invention is therefore based on the problem of specifying a container, the even after closing the vacuum chamber a way to check a possible leakage offers.
- one of the access openings downstream Chamber is provided, in which a valve element is arranged, which when generating the vacuum is opened and closed after the generation of the vacuum is which chamber with a medium containing a diffusible element or a diffusible compound is filled, the or in the case of a leaking closure of the chamber and thus the vacuum chamber through the Access opening diffused.
- the vacuum chamber can be evacuated only through the chamber.
- the valve member closes the chamber, that is, the vacuum chamber is sealed above this valve member opposite the access port.
- the chamber itself is filled with a liquid having the diffusible element or the diffusible compound, which liquid remains in the chamber after sealing the closure opening. If the chamber closure is sealed, the diffusible element or diffusible compound from the chamber can not pass outwardly through the access opening. However, in the event of leakage, the diffusible element or compound will exit at a low concentration, which may be detected using a suitable measuring device sensitive to the element / compound used. A container is still considered tight if the leak rate ⁇ 1 x 10 -7 mbar l / s.
- the container of the invention thus allows a simple way a leak test to, with any leakage very quickly after closing would show the access opening.
- a leak the closure a rework done by the closure again is opened and - if necessary, after replacement of the located in the chamber Liquid while the chamber is sealed by the valve element - be set again.
- the medium used is expediently a liquid, preferably water.
- Helium is preferably used as the diffusible element.
- the chamber itself is in view of the particular in the above-described Beverage drum given space conditions advantageous tubular formed and fastened with one end in the area of the access opening, while at the other end the valve element is provided.
- the chamber itself, so in particular the tube forming it, in particular in the case of the beverage container attached to a threaded opening defining the access opening be in whose thread a screw plug for closing the chamber and thus the vacuum chamber can be screwed.
- a optionally surrounding tubular first chamber, optionally also tubular second chamber is provided, which is in an area below the Valve element communicates with the first chamber and the upper side in particular Has at least one air inlet opening in the region of its attachment.
- this embodiment of the invention is a double chamber arrangement for Use, with the air to be sucked first on the top of the Outer second chamber located air intake openings is sucked, then the outer second chamber passes through and through the passage connection into the first chamber. An aspiration directly into the first chamber is excluded because the two chambers are closed on the bottom side, it Thus, the air can only be drawn through the air inlet opening.
- a chamber connection having holding part, in particular comprising a sealing seat of the valve element, can be arranged over which Holding part, the two chamber are closed on the bottom side.
- valve element can serve any attachable in the chamber valve, the one reversible opening and closing of the chamber opening leading to the vacuum chamber allows. Conveniently, it is as a ball valve with respect to a Seal seat movable ball formed.
- a ball valve with respect to a Seal seat movable ball formed.
- the ball at the sealing seat there is the possibility of the ball from a deformable material and the sealing view of a non-deformable material to form or vice versa, that is, the ball of an undeformable material and form the sealing seat of a deformable material.
- the possibility of both of a deformable material optionally with train different behavior.
- the deformable material is expediently a silicone-based material, but also any other elastic sealing material, while the non-deformable Material is suitably a metal.
- the ball of the ball valve which evacuates the Chamber from its seal seat due to the activity of the access opening coupled pump is moved in the chamber, in the area of the access opening arrives and closes them unintentionally, so that the vacuum no longer could be increased
- the ball over appropriate retention means in the chamber in a close fit position, e.g. above one or more inwardly projecting retaining webs or the like.
- the tubular chamber expediently for this purpose may be formed bent near the access opening. This bend represents a constructive restraint after the ball is not attached to it but the chamber is still open to the vacuum chamber.
- the valve may also be a needle valve with a movable with respect to a sealing seat needle, about the same a secure seal is achieved.
- An advantageous embodiment of the invention - whether in a single-chamber or double-chamber design - Foresees that the seal seat has a central opening with one with a needle seat the needle for sealing cooperating sealing ring, the of the Needle is penetrated, with a positioned below the sealing seat Holding part is provided with an opening with an internal thread, in which the needle with an external thread provided in the region of its lower end is screwed.
- This needle valve can be reversibly opened and closed several times be, that is, it can be made several evacuation steps become.
- the needle valve between different positions be positioned where it either interacts with the thread or is unscrewed from this.
- screwing is expediently on upper end of the needle an engagement for a screwing the needle serving Tool provided.
- the length of the holding part side should Internal thread and the needle-side external thread and the length of the Nadeldichtsitzes be sized so that the needle Oberschraubbar by the thread is and the seal obtained after screwing remains.
- the sealing ring itself should expediently consist of a deformable Material exist.
- a liquid, in particular water, filled which liquid or which water is preferred with helium diffusible element is enriched or enriched after filling becomes.
- the access opening to close what expediently a screw plug in a threaded opening defining the access opening is screwed in, followed by a covering cap completely covering cap on all sides is welded.
- Fig. 1 shows an inventive container 1 in the form of a barrel. Shown is as an example, the bladder 2 of the barrel, in the about a filling 3 a drink or the like, e.g. Beer, can be filled. Also shown is a Partition wall 4, via which an evaporator chamber 5, in which an evaporator 6, with Water is saturated, arranged, and an absorber room 7, filled with a Absorber material 8, e.g. Zeolite, is separated.
- a valve device 9 which is not shown in detail in FIG. In such a Valve means may be e.g. to those from the German patent application DE 102 56 739 known valve device act. Shown is also the Movement mechanism 10, via which the valve device 9 can be actuated.
- the actuation takes place via a manually accessible from outside by the operator Opening and closing lever 11, via which the valve device is opened and closed and the self-cooling process can be started or stopped.
- the passage from the evaporator chamber 5 to the absorber space 7, in which at the beginning of the self-cooling process vacuum prevails is opened.
- the water stored in the evaporator evaporates, for which energy is required, which is the present in the bubble 2 drink in the form is removed from heat.
- the evaporating water passes through the valve device 9 into the absorber space and is absorbed by the absorber material 8, e.g. the Zeolite, absorbed.
- the evaporation process and thus the self-cooling Continue until either the absorber material is completely saturated with water is, or until the valve device 9 is closed manually by the user.
- FIG. 1 in the upper right area, the access opening 12 is further shown on the evacuation of the evaporator chamber 5 and optionally also the absorber space 7 takes place with open valve device 9, both a vacuum chamber represent.
- Figures 2 and 3 show a detailed view of this area. Shown is on the one hand, the lid 13 of the container 1 of FIG. 1 and the access opening 12, which has a threaded sleeve 14 which is provided with an internal thread 15 provided is formed. The threaded sleeve 14 is firmly welded to the lid 13. At the lower nozzle portion of the threaded sleeve 14 is a bent Welded tube 16, which forms a chamber 17, the access opening 12 is connected downstream.
- the tube 16 and thus the chamber 17 extends in the Area of the evaporator chamber 5.
- a sealing seat 18 is provided, which in the following still described meadow interacts with a ball 19.
- the sealing seat 18 in conjunction with the ball 19 together forms a ball valve, via which access to the vacuum space 5 can be opened and closed.
- Fig. 2 shows in the form of a schematic diagram of the arrangement during the generation of the vacuum, so while the evaporator chamber 5 and possibly also the Absorber space 7 are evacuated.
- an evacuation pump 21 via which the air is sucked out of the spaces 5, 7, as indicated by the arrow A. is shown.
- the ball 19 is due to the pressure prevailing over her pulled up. Due to the curved shape of the tube 16 and thus the Chamber 17 in the upper, the access opening 12 near area, the ball 19 held in a position that prevents them from sealingly in front of the access opening 12 sets, which would prevent further pumping.
- the vacuum chamber can evacuated in the form of the evaporator chamber 5 and optionally the absorber chamber 7 become. This takes place until the pressure in the vacuum chamber is equal to the is pressure generated by the pump. In this case, the ball 19 falls due to weight down and engages the sealing seat 18. Because of in the vacuum chamber prevailing vacuum deforms the ball 19, which consists of a silicone material or silicone is, as shown in Fig. 3.
- the sealing seat 18 itself is preferably made of metal. Nevertheless, the configuration can also be reversed that the ball 19 is made of metal, while the sealing seat 18 of a deformable Material such as Silicone is. In this way, access from the Chamber 17 to the vacuum chamber, here the evaporator chamber 5, closed.
- a Screw plug 23, here a collar screw, with a sealing ring 24 firmly screwed in the threaded sleeve 14 .
- a cap 25 is placed on the locking screw 23 and welded to the edge of the threaded sleeve 14 to another seal to realize.
- the inventively provided chamber allows multiple opening and Close to what during the preparation of the described beverage container with the self-cooling device is required.
- the manufacturing process is designed as follows:
- the tube 16, the threaded sleeve 14 and the sealing seat 18 form a preassembled Unit, at a suitable time on the threaded sleeve 14 in the lid. 5 is welded.
- the deformable ball 19 via the access opening 12 is pressed into the chamber 17.
- the pump 21 to the Access port 12 coupled and the evaporator chamber 5 and optionally also the absorber room 7 is evacuated. This migrates as already described the ball 19 up so that the chamber valve is open. Upon achieved desired Vacuum drops the ball 19 back down and closes the valve as a result of the investment in the sealing seat 18th
- the chamber 17 is filled to the brim with cold water. This protects that Valve consisting of the ball 19 and the sealing seat 18 from overheating in subsequent regeneration process. Then the locking screw 23 screwed, whereby the water in the chamber 17 displaced and a hydraulic pressure in the chamber is built up on the ball 19.
- the container is regenerated.
- the absorber room or the Absorber material is saturated with water.
- the container is heated from the outside, whereby the water evaporates from the absorber material and over the now open Valve device migrates into the evaporator chamber and the evaporator 6 saturates. This raises a pressure build-up in the container chamber to about 1,000 mbar,
- a counter-pressure is created by extending the water column above the Ball 19 is constructed, which closes the ball valve. Should still be a leak Adjusting in this area would only release water from the chamber 17 flow into the vacuum chamber, the vacuum generated would be substantially unchanged.
- valve device After regeneration, the valve device is closed and it follows the actual Nachevaku réelle or end evacuation.
- Fig. 4 shows another chamber and valve embodiment. Shown is also shown here a first tube 27 which defines a tubular chamber 28, and with its upper end to a threaded sleeve 29 and with its lower end a holding part 30, whose function will be discussed below, arranged is.
- the first chamber 28 is encompassed by a second outer tube 31, a second outer chamber 32 between the first tube 27 and limited to the second tube 31.
- the second tube 31 is also on the top side on the Threaded sleeve 29 and the bottom side also arranged on the holding part 30. in the upper portion of the attachment of the second tube 31 to the threaded sleeve a plurality of air inlet openings 33 are provided, via the air into the second chamber can be sucked during evacuation.
- the holding part 30 seals both chambers 28, 32 downwards. It has one Air passage opening 34, via the air from the second chamber 32 in a Chamber 35 of the holding part can enter.
- the valve element 36 which is designed here as a needle valve, positioned.
- This valve element 36 comprises on the one hand a needle 37, on the other hand a sealing seat 38 with a Sealing ring 39, which is loaded by a spring ring 40 inside.
- the diameter of the sealing ring 39 is dimensioned so that the sealing seat 41 of the needle 37, formed by their elongated outer circumference, received positively in the sealing ring 39 can be.
- the elongated sealing seat 41 of the needle 37 is followed by a conically tapering section 42, which merges into a connecting portion 43, in which a section 44 with an external thread 45 connects.
- This external thread engages in an internal thread 46 of an opening 47 on the holding part 30, so it can in this be bolted.
- the needle 37 via the at the top provided tool engagement 48 screwed up until the needle sealing seat 41 is released from the sealing ring 39, see Fig. 5.
- the sealing ring 39 as appropriate the entire sealing seat 38 is made of silicone, springs slightly inward. Obviously, however, the valve is opened, air can after putting on the pump via the top air intake openings 33, as shown by the arrow in the outer second chamber 32, from there via the air passage opening 34 in the inner holding part-side chamber 35 and via this via the valve opening 49 in the first chamber 28 and from there to the pump. Visible is the Needle 37 is still screwed into the thread 46.
- valve After opening the screw plug over the Tool the needle 37 gripped and back up in the in Fig. 5 shown Evacuation position screwed. So it is possible at any time, this valve device to press several times.
