Description

System for serving portioned and tempered drinks in mobile use

The invention relates to a system for providing portioned and tempered drinks in mobile use, wherein the use in aircraft is particularly advantageous. At least individual elements of the system are also suitable for the transport and safe storage of other foods or pharmaceutical products.

For the presentation of different drinks that are to be made available as hot drinks or chilled drinks, previously recorded in different containers or containers drinks are stored as finished product in a cooled form, transported and then administered. This requires a high logistic effort for the desired different drinks. In addition, a far too large number of vessels is usually transported or containers without being needed. Thus, about 70% of the drinks carried in airplanes are not consumed during a flight. This results in a transport mass that is not really required, which in turn increases energy or fuel consumption.

For hot drinks, it is customary on site, ie also in a vehicle, to heat water to the required temperature and then to prepare the respective beverage with the hot water. For this purpose, an increased energy requirement is also required, which is unfavorable in mobile use and negatively affects the fuel consumption of a vehicle.

In mobile use, therefore, incur increased costs or a reduction in the useful mass is accepted, which in turn is reflected in increased costs.

Frequently, however, cooling or holding devices are also used in mobile applications, with the help of which the respective temperature of beverages or other foods should be maintained over a longer period of time. Again, the required energy consumption and the intrinsic mass of such facilities adversely affect.

It is therefore an object of the invention to provide opportunities with which a variety of tempered drinks can be made available for consumption and thereby the plant technical effort and energy consumption can be reduced.

According to the invention, this object is achieved with a system having the features of claim 1. Advantageous embodiments and further developments of the invention can be achieved with features described in the subordinate claims.

The system according to the invention is formed with a plurality of elements which can be variably combined with one another and supplemented by further elements. There is at least one heat-insulating container available. In the container then at least one container containing tempered water can be used.

In addition, at least one vessel for the actual presentation of the respective tempered drink may be present. The vessel may be a glass or a cup for a beverage portion but also a jug for several portions. To provide different drinks, at least one dispenser element is present. The dispenser element contains a liquid or powdered concentrate for the respective beverage, the concentrate content should be such that it corresponds to a beverage portion of the respective container to be administered, ie it can be dimensioned for a glass or a cup but also for the contents of a jug. For example, different juices, tea or coffee drinks with a concentrate and the appropriately tempered water can be prepared for consumption on the spot. On request, it is also possible to prepare a hot soup with a suitable concentrate.

A container containing water may be centrally heated, eg at a caterer, or cooled and then placed in a thermally insulated container. In the closed container, the insulation can then be used to maintain the temperature of the water for a sufficiently long period of time, whereby a slight heating or cooling are tolerable. So the tempered water can be transported and transported for example in and to a vehicle (eg aircraft). If necessary, then a required amount of water can be removed from the container and placed in a vessel together with the concentrate from the donor element, where appropriate, a stirring can take place. For stirring, a dispenser element designed for this purpose, for example a rod-shaped or spoon-shaped element, can be used. The particular concentrate may be contained in a closable cavity.

In addition, when transporting from a caterer to the place of actual consumption (e.g., a vehicle), suitable insulation for heated or refrigerated or refrigerated containers should also be employed.

In a further development of the invention but also the thermally insulated container or another similar or similar trained thermally insulated container can be used to keep a vessel with the respective already prepared beverage on the temperature. Thus, one or more cans can be inserted into such a container. In the sealed container, the temperature of the drink over a longer period of time can be kept constant or with only slight warming or cooling. This period can also be increased by the vessel is also formed heat-insulating.

Containers may be of standard standard dimensions so that they can be integrated or used in existing facilities, such as This is the case, for example, in galleys.

A container should have a heat transfer coefficient of less than 0.05 W / mK, preferably less than 0.005 W / mK.

In order to improve the Thermostatierwirkung containers, but possibly also containers for water or vessels with at least one vacuum insulation panel element should be formed. These are with one

Carrier and / or a porous material formed, which is sealed gas-tight to the outside, wherein the cavities have been evacuated before the closure. For sealing, suitable films, preferably also multilayer, can be used. The gas-tight closure can also be achieved alone or in addition with a rigid closed outer shell or shell of a metal or a suitable plastic. More concrete possibilities for a suitable structure will be discussed in more detail below.

In a heat-insulating container, a further container or a contoured insert element can be used. A heat-insulating container may also be accommodated in a container that can fulfill a protective function against external mechanical impact. Such containers may be formed of a suitable plastic in or on the walls of which insulation layers may be present. But it is also possible such a coating on the outside of a container.

A pressure compensation opening may also be present on a heat-insulating container and / or a container, via which, for example, outgassing vapor can be discharged. escape or with which condensation can be avoided. There may also be a suitable membrane or valve.

It is particularly advantageous to geometrically design and dimension the interior of heat-insulated containers in such a way that the internal volume can be optimally utilized. With accordingly designed and dimensioned containers for water or vessels, this can be achieved. square

Geometries are particularly suitable for this. So cuboid interiors of containers in combination with containers for water or vessels with a square (rectangular, square) cross-section of a set and dead spaces in a container can be largely avoided.

But containers for water can also be used from a plastic film in bag form, which is due to the flexibility of the interior geometry of a

Adjust the container well and have it completely filled.

However, it is also possible to provide such containers for water with an outer shell having increased mechanical strength and a liquid-tight inner film. The outer shell may be made of a compostable material, such as e.g. Kartonage, consist and a cuboid shape of a container can be selected.

However, flexible containers for water or other liquids can also be kept tempered in an insert element. At least one such container can be inserted into an insert element. An insert element can be an open tray be.

It is advantageous to form the bottom of a heat-insulating container, insert element or a container inclined at an oblique angle. With an inclination angle in the range of 5 ° to 10 °, a gravitational force-related leakage of the liquid or of water can be achieved without further aids. However, such a tendency of the soil can also be present preferably in an insert element.

Then, a cavity kept underneath the insert element in a heat-insulating container or container can be used to accommodate further elements, such as e.g. Latent heat storage elements, electrical energy storage elements, heating or cooling elements u.a.m. be used. Insert elements can also be easily and simply replaced.

In the invention, heat pipes or two-phase thermosiphons can also be used for a temperature control. In this case, the internal pressure and the fluid contained can be tuned to the particular desired temperature. So a temperature can be kept better and longer. In this case, a cooling or a longer keeping warm can be achieved.

Even with latent heat storage elements, an adaptation to desired temperatures can be taken into account if a medium is used for which a phase transition takes place in the region of the desired temperature. Thus, while holding a medium can be used, in which a phase transition occurs a few degrees Kelvin above the desired temperature.

Within heat-insulating containers, a homogeneous temperature can be maintained. For this purpose, suitable elements may be present with which a targeted influencing of the air flow inside can be achieved. For example, flow masks or channels can be used. With fans, a circulation but also advantageously the flow of heating, cooling or storage elements are directed into other interior areas, so that heat or cold can also reach into more distant interior areas. In this case, a control o- the control of fans made, which can preferably be temperature-dependent. It is also possible for a plurality of fans to be present on one unit, which achieve their maximum power in different directions, so that different flow conditions can be set and increased variability in temperature compensation in the interior can be achieved. Several fans can be arranged side by side but also one behind the other.

To determine the average temperature in the interior, the fans can be operated so that a flow is initiated for a short time in one direction and then in another or the opposite direction. The temperature change can be detected and taken into account.

Fans may conveniently be interchangeable. They can be plugged onto appropriate plug-in contacts for use and easily removed for a required cleaning. With a watertight design of fans, they can be easily, quickly and inexpensively cleaned and then used again without problems.

The containers can also be at least one outlet element for the portioned delivery of tempered Have water or other liquids in vessels, which may be formed for example with a closable valve. Containers may be formed with a plurality of separate chambers, so that correspondingly more liquids or different drinks may be included. At the individual chambers can then be an outlet element. It is particularly preferred to use interchangeable outlet elements, which can also be used as a disposable article. They can then be attached to suitable nozzles of the container, insert elements or a heat-insulating container for use, for example by simply plugging or plugging. Outlet elements can be designed as single or reusable valves. With multi-way valves, for example, a pressure equalization during filling of liquid is possible.

The spout can be arranged on the container so that water alone expires gravitational force caused and to another valve or a waterproof membrane can be present so as to allow the inflow of ambient air and avoiding a negative pressure in the container. However, the water can also be removed by the assistance of a gas under increased pressure from the container. For a gas pressure vessel can be connected to the container. Here, a combination with a suitable compressor can be used to provide an increased gas pressure. This can be, for example, a pump, which can also be operated by hand if necessary.

In order to further reduce the unwanted heating or cooling of water or a drink in a thermally insulated container, there is the possibility insert appropriate latent energy storage in the container. In this case, may be present inside a thermally insulated ^• Behältnises recesses or receptacles with an adapted contour of such Latentenergiespeicherele- elements. But it is also possible alone or in addition to form such contours of containers for water, inserts or vessels, so that cavities are present, in which such latent energy storage elements or other suitable for a temperature control elements (heat pipes) can be introduced. Thus, an intimate contact can be achieved and, in addition, a form-fitting hold, avoiding slipping of containers or vessels within a container, can be achieved. Latent energy storage elements can be adapted with their outer design complementary to contours of a container and / or to outer contour elements of containers or vessels to be enclosed in containers and kept isolated. You can, for example, have a concave contour into which a convex contour of a container or vessel is almost exactly insertable.

It can also be advantageous to design and dimension latent energy storage devices so geometrically that they can be used in various containers in combination with various insert elements, containers or vessels, but in each case in the same form as a standard element.

In addition to the latent energy storage already mentioned but can also be provided on a container use of cooling or heating elements. However, since it is desired for the invention to operate autonomously, ie without connection to a power supply, for example an electrical system of a vehicle, the Power supply locally there done. Accordingly, fuel cells or photovoltaic systems are suitable. With the electrical energy thus obtained, pelletizing elements can be used for cooling or heating. However, an externally accessible connection, for example a low-voltage connection, may also be present for an electric power supply. However, other types of voltage can be used. This connection can be designed so that it can also be used as an interface for a data transfer, eg stored temperature data.

However, a supply of electric energy can also be effected without contact by inductive or capacitive transmission. Then, corresponding antennas or capacitors may be present, for example, in the housing of heat-insulating containers.

In the invention, it is also convenient, the individual

To provide elements with identification elements that may be useful for logistics, use and data verification. For this purpose, bar codes which are known per se but also RFID-based identification elements which can be operated by wire and without contact can be used. Identification elements can be attached to containers, containers, containers and dispenser elements.

Donor elements can, as already mentioned, be rod-shaped or spoon-shaped. But it can also tubular bags, preferably narrow elongated, are used. Since it is possible to use, in addition to powdered, preferably liquid concentrates, a cuff which at least partially covers an outlet opening should be provided on one end face. be present, which can avoid contamination of the fingers when opening and emptying.

Donor elements can also be held together with a vessel. A donor element can be arranged within a vessel (cup or jug). Before filling with tempered water, a closing element can be opened or removed, so that a mixture of concentrate and water is contained in the vessel after filling with water. A donor element can also be arranged on the bottom of a vessel or also form the bottom of the vessel.

With donor elements, it is also possible to produce it completely or else in sections from a material, substance or mixture of substances which is water-soluble, so that the concentrate can be released on contact with water. It is also possible with preference to use materials or substances which are only water-soluble or better water-soluble at a predeterminable temperature. These may be, for example, cellulose or sugar-based substances.

Thermally insulated containers may be provided with closable openings for refilling or removing containers, vessels, other food, articles or pharmaceuticals contained therein. These can be simple slides or cover elements. But a closure can also be achieved with a door element, in particular in a stationary use, for example in a galley. This should be a secure closure, which can prevent unintentional opening or leave open. A closure can be used as a double Be formed final, with both closure elements act independently and one alone sufficient to ensure a tight closure of the container. In addition, further EIe- elements, such as magnetically acting, may be present. At doors or cover elements seals, preferably labyrinth seals can be formed.

However, a closable opening can also be formed there, via which a refilling with water or liquid can take place.

Particularly in the case of containers used in a stationary manner, it can be advantageous to provide an outlet element for water directly from a container to which a container of water can be connected. Tempered water can then be filled from the container received in the container protected via the outlet element in a vessel for providing the respective beverage prepared with the concentrate without the water-containing container must be removed from the thermally insulated container. The outlet element can be formed from a material (for example ceramic, plastic) with a low thermal conductivity.

Heat-insulated containers can also be designed for transport with at least one carrying handle element. There is also the possibility that guide rails are attached, with which an insertion into an existing galley system is possible. This allows compatibility with existing systems and elements (drawer, ovens, trolleys, ünits, SpiceBox), taking into account the dimensions of these and thereby existing breakpoints, - elements or fixing elements can be achieved. In thermally insulated containers and insert elements can be used. Contour elements in the form of recesses or receptacles may be formed on such insert elements, into which correspondingly suitably contoured objects, packaging, containers, vessels or other are inserted and held therein positionally secure even during transport. Insert elements should be made of materials or materials that have low thermal conductivity and, if possible, low physical density. They should have sufficient strength and, if necessary, be reusable. This can be achieved for example with cardboard or plastics, such as plastic foam parts. The latter can also be cleaned.

On or in heat-insulated containers, the internal temperature optically indicating elements should be present. These can be reusable temperature strips, in which temperatures are displayed, for example, by different shades or even analog (towing) pointer thermometer.

A temperature determination or temperature monitoring can also be achieved with suitable sensors and possibly an electronic storage medium. Here then electrical energy can be used by a suitable element on site (fuel cell, photovoltaic) or from an energy storage element. The respective temperature can also be displayed on a display. It can also be provided with evidence of compliance with certain temperatures to consumption with suitable data storage. The reading or reading of data can also done wirelessly. However, this is also possible with a suitable externally accessible standardized interface.

This is also possible in connection with wireless RFID technology, wherein possibilities of wireless energy transmission can also be used in combination with an existing electric energy storage.

The indoor temperature indicating elements should be waterproof to meet required hygiene requirements and allow cleaning.

It can also be advantageous if it is readily apparent from the outside whether cooled or heated water or correspondingly other articles, foods or other objects are / are contained in the interior of heat-insulated containers. This can be achieved with an indicator element attached thereto. Such an indicator element may be obtained, for example, by showing a color, e.g. blue or red, show this. In this case, a corresponding indicator element can simply be inserted into a receptacle or indicate the respective state by means of a pivoting movement. But it can also be the state displayed by a readable lettering.

To allow optimum space utilization and also good handling, vessels for administering tempered drinks, in which preferably several beverage portions are contained, can have an outlet element (discharge spout) and / or a gripping element into which a hand can engage. The design and dimensioning with appropriate arrangement on a vessel can be chosen so that complementary contours are present. In this case, a projecting spout can be contoured so that it can be inserted into a corresponding contour, which is formed for example in the region of a grip element of another vessel, when both vessels are adjacent. This also means that a movement of the juxtaposed vessels can be avoided even when acting from the outside accelerations. Thus, with improved functionality of the vessels a secure hold and optimal space utilization can be achieved, and this is also possible if a plurality of such vessels are accommodated in a thermally insulated container.

The already mentioned vacuum insulation panel elements can be produced with porous materials or materials, such as, for example, microporous aerogels (silicic acid). In addition, a honeycomb structure made of a material of low thermal conductivity can be present as a carrier structure in such a panel element. The hollow honeycombs (octahedra or other geometries) may be filled with the microporous material. The material used can be a synthetic resin coated Nomex paper but also a suitable plastic. The whole can be enclosed in a cover foil, which can also be glued to the honeycomb structure. In the cover sheet, a perforation may be formed for evacuation. The openings of the perforation can be gas-tight again after the evacuation, which can be achieved by an additional film but also by a carrier which can be connected to the film. The carrier may be a plate or a differently shaped carrier element, which is the desired shape is adapted, as may be the case for example in such an insulated vessels. Carrier (made of eg metal or plastic) can form an all-round closure and the gas-tightness can be achieved by welding.

Strength and insulation effect can be further increased if two honeycomb structural elements are arranged one above the other. Although the honeycombs are aligned in the same direction but offset from one another, so that the respective contact surface is reduced.

With vacuum insulation panel elements, a large thermal insulation effect can be achieved with a very small wall thickness. With a wall thickness of 7 to a maximum of 12 mm, the same effect can be achieved with a heat conduction coefficient of about 0.005 W / mK as with other thermal insulation materials known per se having at least twice the thickness, which has an advantageous effect in mobile use.

Thermal bridges should be avoided or preferably no thermal bridges should be present. A reduction is, as explained above, possible by the staggered arrangement of the honeycomb structures. No thermal bridges are achieved, for example, when a homogeneous porous material is enclosed in a vacuum-tight manner and also a constant wall thickness is maintained.

By standardized dimensions of the heat-insulated containers used and the consideration of these dimensions even in the case of the invention can be used for containers for water and vessels improved handling, security and a more optimal use of space is possible. Additional connections for energy or in a vehicle previously existing tanks and lines for the preparation of hot drinks, which cause a very high maintenance, are no longer necessary.

By a variety of different concentrates containing donor elements is a great deal of flexibility for the disposal of diverse drinks given without the mass that must be transported along with this is considerably increased, which in turn reduces transport costs and / or increases the potential payload.

Vessels, in particular those which are provided for receiving a portion, can be designed as a compostable disposable article.

The invention will be explained in more detail by way of example in the following.

Showing:

Figure 1 used in the invention elements;

Figure 2 is a heat-insulating container with container for water and

FIG. 3 shows an example of a cable guide which can be used in the invention.

FIGS. 1 and 2 each show a heat-insulating container 1 which can be closed with a cover element. From an outside

Protective casing protected from a plastic are Vacuum insulation panels in the container 1 and cover element 2 available.

The upper end face of the container 1 and the corresponding circumferential edge region of the cover element 2 are designed to be complementary so as to form a labyrinth seal. In this case, additional sealing elements, such as sealing lips may be present, which are insertable into depressions.

Outside there are handles 3 and bars 4 for improved handling. The cover element 2 can be connected to the heat-insulating container 1 by means of two hinge elements 5 and this can thereby be closed.

In the heat-insulating container 1 can here a container 6, which is also heat-insulating, are used. In the container 6 tempered liquid or water can be directly contained. However, there is also the possibility not shown in Figure 1 to use at least one further flexible container, which has been made of a flexible film. The shown container 6 can then be understood as an insert element.

Like the container 1, the container 6 can be closed with a lid member 7. Again, the seal should be formed as has already been described for the container 1. In this example, a filling opening 9 is present in the cover element 7 of the container 6, which can be closed with a closure element 8. At the filling opening 9 and closing element 8, sealing elements are again present. The closure element 8 can be used alone or additionally with the aid of the cover element 2 of the container 1 are kept closed in the filling opening 9 when the lid element 2 closes the container 1 and thus the closure element 8 is pressed into the filling opening 9, so that the outer edge of the closure element 8 is pressed against the inner edge of the filling opening 9 ,

On the outside of the heat-insulating container 1, a closable outlet element 10 is provided in this example, from which temperature-controlled liquid or water can be removed in portions. In this case, a connection in the form of a line to the interior of the container 6 (not shown) is present. In the closure element 8, a pressure compensation opening, a valve or a membrane for pressure equalization may be present.

FIG. 2 shows an example of a container 6, which has a cylindrical shape and can be inserted into a heat-insulating container 1, which is formed analogously to the container 1 according to FIG. Here it can be seen that an outlet opening 11 is provided on the container 6 and arranged there so that it communicates with a further outlet opening 12 on the container 1. Thus, the outlet element 10 can be easily guided through the two outlet openings 11 and 12 and withdrawn from the container 6 tempered liquid. The container 6 is closed on all sides except for the outlet opening 11 and the filling opening 9 in this example.

Due to the cylindrical shape remain within the heat-insulating container cavities that are available for other elements, such as energy storage, sensors, Datenentrans- and storage, heating, cooling and temperature homogenization available. However, it can be used in an unillustrated form in the container 1, an insert element with complementary contour with which the container 6 in the container 1 can be securely fixed. However, an insert element can also receive and fix the additional elements mentioned above.

FIG. 3 shows a very advantageous example of a cable guide. Since it may be necessary in the invention, signals, data or even electrical energy can not be transmitted wirelessly, which may be required in the interior of a container 1 or in or to a container 6 or an insert element, suitable lines must be introduced from the outside become.

A passage of a cable 13 or a line through the wall and in particular by a vacuum insulation panel significantly reduces the insulating effect and should be avoided as far as possible. It would also be a high cost for a possibly required replacement of a defective line or a cable 13 is required, since the heat insulation must be observed and renewed after replacement.

Since, however, openings are present anyway on the containers 1 or containers 6, they can be used to guide cables 13 or lines into the interior.

As already mentioned, cover elements 2 and 7 or otherwise formed openings may be provided on containers 1 or containers used in the invention Container 1 or container 6 must be connected, this can be done by means of hinges.

Preferably, double hinge joints can be used.

Also, it may be critical to bend such flexible cables 13 or lines frequently, as this can lead to cable breaks. To counteract this, a line or a cable 13 may be spirally wound at least in one area. This area may be wound on a hinge about the axis of rotation 14. During a movement, no kinking or excessive bending of a line or a cable 13 occurs in this otherwise critical area, since during the pivoting movement of the cable 13 or the line, the spirally wound area there picks up the movement. The diameter of the spiral increases and decreases depending on the direction of movement. A cable 13 or a line can be attached to the heat-insulating container 1.

Advantageously, there may be an interruption on a hinge at a transition point for a cable 13 or a line.

At one end of a cable 13 or line, a plug with connection contacts can be present, which can be inserted into a counterpart for transmitting signals, data or electrical energy. Such a counterpart may be installed on a heat-insulating container on the outer wall. Thereby, a possibly required replacement of a cable 13 or a line can be simplified.
