Description

Disposable container

The invention relates to a disposable container such as a cup, pot, can or the like. in particular for the absorption of at least partially liquid food such as coffee, tea, soup or the like., With a bottom wall and a side wall containing cup wall and a receiving space surrounded by the two walls for the food.

Such disposable containers are used, for example, in the form of a cup, to provide portioned amounts of coffee in coffee machines. The coffee is heated by the coffee machine and placed in a cup-shaped container provided poured off, which can then be removed. Other areas of application of the above Disposable containers called are in the packaging industry, for example in the packaging of ready-made soups. In this case the container is disposable with a removable cover, for example a film or the like.

sealed and contains a product that no longer requires any ingredients and only needs to be heated. The number of areas of application described above Disposable containers can be continued at will. All known embodiments have the disadvantage that a heating of the received in the container food just outside the container itself and usually using an additional one Vessel and a heat source such as a stove, cooker, immersion heater or the like Device can be carried out. However, these devices are in those places where the above products, e.g.

Ready-to-use soups, which should be consumed, are often not available, for example at work. Furthermore are for camping and hiking needs Although smaller cooking appliances are available, these are usually relatively bulky and depending on an energy source such as gas or petrol. In addition, are the cooking appliances that can be used are relatively expensive and therefore often unprofitable.

The invention is based on the object of remedying the above disadvantages and to create a disposable container that makes it possible to use those contained therein Food or the like. with cheaper production and compared to known ones Disposable containers of only insignificantly larger dimensions without the need for equipment quickly to be heated to the desired level.

This task is solved by dat! the bottom wall and / or the side wall contains a cavity in which two spatially separated reagents that can be connected to one another from the outside are accommodated, which, when brought together, react with one another to give off heat.

According to the invention, the heating of the disposable container contents, e.g. Coffee or soup, can be carried out directly in the disposable container itself, so that no additional vessel is required. There is no device for heating required, the heat required for heating is only provided by the heat that is released Heat of reaction delivered when the two reagents are mixed. This has the special The advantage that the contents of the cup are heated completely in almost every situation can be done independently of a bulky, expensive cooking appliance.

The disposable container according to the invention can also be used primarily in the camping area can be used cheaply or for a short coffee or at work to warm a soup. The disposable container according to the invention is advantageously constructed Known disposable containers that are only slightly larger than comparable contents, its production can also be carried out very inexpensively due to its simple structure. This is in the single-use industry, where experience has shown that a product is packaged the most expensive are, especially beneficial. The disposable container according to the invention is can be used in a variety of ways, for example two embodiments are conceivable, the container being offered in the one embodiment without content, so to speak as a mere "heating container". This "heating container" can be used at any time with any warming contents are filled.

The other embodiment sees one already with certain content filled and closed container. Furthermore, the invention can Disposable container advantageously at the same time both as a still and as a drinking device be applied, the effort to prepare a smaller meal is thus kept as low as possible. Disposal the disposable container in the Connection to their use is unproblematic and can be done through the usual waste disposal routes take place. The end product resulting from the reaction of the two reagents is neither toxicologically nor in any other way of concern, so that the environment is not burdened more than by the usual disposable containers mentioned at the beginning Art.

Advantageous further developments of the invention are set out in the subclaims listed.

The developments according to claims 2 and 3 are particularly simple produce, in particular the development according to claim 3 additionally one fastest possible heating of the container contents guaranteed. Between the the The mixed product of the two reagents and the contents to be heated deliver heating heat the largest possible heat transfer surface is given, which takes up the heating time shortened to a minimum.

The development according to claim 4 prevents one of the two Reagents inadvertently escapes from the cavity. This is particularly advantageous when the disposable container is being transported.

The advantageous development according to claim 5 ensures on the one hand, that the two reagents do not come into contact with one another inadvertently, on the other hand but can be mixed with one another without any effort if necessary. Preferably only one movement is necessary to get the reaction going.

Claim 7 describes an advantageous development that is optimal Mixing of the two reagents guaranteed when the separation chamber is opened.

The further development according to claim 9 is in particular also viewed together with the development according to claim 8 of advantage, as due to natural gravity it is always ensured that the two reagents meet when the separation chamber is opened. At the same time, the development according to claim 9 can be particularly simple and without produce great effort.

The development according to claim 10 is simple and inexpensive to produce, at the same time, the plastic material serves as an insulator, so that the disposable container can be grasped without the risk of burns even if there is a lot of heat in the cavity can.

Claim 12 describes an advantageous development in which a rapid transfer of the heat of reaction to the container contents to be heated can. In connection with the measure according to claim 11 is again to the outside a good insulation is given.

The development according to claim 13 is particularly easy to manufacture. Preferably, an inner and an outer container are each manufactured and separately after introducing the two reagents assembled together. Preferably if the two containers overlap in the edge area of the container opening, see above that a gluing or welding can be carried out that the two containers in a fixed assignment to each other.

The development according to claim 14 enables simple opening the separation chamber from the outside. Particularly in the case of further training one of claims 15 to 17 can open the separation chamber without any noticeable effort be performed. The development according to claim 18 facilitates the opening of the From the outside of the reagent container.

The advantageous development according to claim 19 guaranteed by simple means an intense heat release that a rapid heating of the Disposable container contents enabled.

The further development according to claim 20 is characterized in particular when viewed together with the measure of claim 21 characterized by a high level of responsiveness, wherein at the same time the two funds used can be obtained cheaply. This affects favorably on the total production costs of the disposable container according to the invention the end. Advantageously, the combination of potassium permanganate takes place with glycerine without external heat an exothermic reaction, the heat released is used to heat the contents of the container.

By the measures of claims 22 and 23, a dilution of the Oxidizing agent take place, so that the ferocity of the reaction can be limited when the two reagents are mixed. Depending on the mixing ratio between the passive agent and the oxidizing agent can be the reaction rate can be varied while maintaining the final amount of heat released. Farther the passive means preferably also ensures that after the reaction of the two Reagents remaining liquid is bound. A "leakage" is thereby avoided.

Through the development according to claim 24, a dilution of the Reagent are made to contribute to the violence and speed of the reaction Control connection of the two reagents. The measure according to claim 25 is in particular of advantage with regard to claim 21, since glycerine can be very easily diluted with water leaves. In addition, water is very cheap, which is the cost of the invention Keeps disposable container low.

The measures of claims 26 to 28 are the prerequisite for that a foam can arise after the reaction of the two reagents, which, among other things, ensures that the heat generated is evenly distributed in the cavity will. The foam preferably fills the entire cavity, so that the to be heated Contents, with the exception of the surface facing the filling opening, from all sides is surrounded by the heat-emitting foam. This keeps the heating time to a minimum.

At the same time, the foam serves as an insulation medium after it has cooled down between the inner and outer walls of the container , so that on the one hand the heat radiation of the heated container contents and thereby their Cooling is prevented and, on the other hand, grasping the cup without the risk of burns is possible because the heat radiation to the outer wall of the container is largely prevented is.

The developments of claims 29 and 30 have in particular in Their combination has the advantage that an optimal mixing of the two reagents after initiation of the reaction is guaranteed.

The development according to claim 32 promotes the formation of foam Interaction of the gas with the foaming agent. At the same time, however, this is the case with the Reaction resulting gas bound in the foam, so that no to the outside of the beaker Gas leakage or only in very small amounts is detected. The measure according to claim 33 ensures that the released gas is harmless.

The development according to claim 34 ensures that the end product resulting from the reaction of the two reagents does not come out of the cavity can escape, even if the same has an opening, for example for implementation having a pull cord for opening the separation chamber. This also makes it possible that the disposable container according to the invention transported after completion of the reaction what is desirable, for example, in the camping or hiking sector is because there are not always appropriate waste bins to hold the used ones Disposable container be available.

The measure according to claim 35 ensures that the end product is toxicologically is not questionable.

The development according to claim 36 describes an advantageous mixing ratio of the individual components of the reagents, in which an optimal reaction between the two reagents is guaranteed. It is advantageous with this mixing ratio achieved that the resulting end product within a very short time of about 10 to Heated to a desirable temperature of 70 to 80 degrees Celsius for 15 seconds is. On the one hand, this temperature is favorable for rapid heating of the To ensure the contents of the container and on the other hand prevents the container itself is destroyed by too high a temperature.

However, it is still possible, in particular by changing the mixing ratio the amount of heat generated between the oxidizing agent and the reactant to control and to enlarge or reduce as needed.

The invention is explained in more detail below with reference to the accompanying drawings explained. 1 shows the disposable container according to the invention in a first one Embodiment in the form of a cup and in a longitudinal diagram, Fig. 2 shows a section from the disposable container from FIG. 1 according to the Section II and FIG. 3 shows an enlarged section of the area of the separation chamber in a further embodiment of a disposable container.

Referring first to Fig. 1, a first embodiment of the Disposable container according to the invention shown. This is in the present example Cup-shaped and contoured in the manner of a conventional drinking cup. the entire container wall 3 is composed of a circular disk-shaped bottom wall 1 and a hollow cylindrical side wall 2 attached to its outer circumference. In an axial longitudinal section according to FIG. 1, there is thus an approximately U-shaped Shape.

The free container front edge 4 pointing away from the bottom wall 1, which is also circular, encloses a container opening 5, which in a laterally limited by the side wall 2 and below by the bottom wall 1 Receiving space 6 for preferably liquid food such as coffee, tea, soup tastes good.

or the like / in the illustrated embodiment is the recording space 6 is filled with a liquid 7 to about 3/4 of its volume. The recording room 6 has the shape of an upside-down truncated cone, which is due to that the side wall 2 starting from the bottom wall 1 in the axial direction one has a steady increase in diameter. The shape of the container or the receiving space 6 is of course not specified, any other container shape, for example cuboid or circular cylindrical would be possible.

The one-way container shown in FIG. 1 is a disposable container already filled with a liquid 7 offered on the market, its container opening 5 in the manner of a commercially available cream or milk cup with a cover 8 is closed. This cover 8 consists for example of a Aluminum foil and is in the area of the container opening 5 on all sides around the outer circumference of the container front edge 4 flanged (not shown). Another mounting option is for example the gluing of the lid 8 directly on the container front edge 4th

Both the bottom wall 1 and the side wall 2 are complete Double-walled, with the container inner wall pointing in the direction of the receiving space 6 9 and the outwardly pointing container outer wall 10 have a common cavity 11 lock in. The cavity 11 extends both in the side wall 2, as well as in the bottom wall 1 and is in the area of the container front edge 4, below Release of a smaller opening to be explained later, completely closed (at 12). In other words, the cavity 11 can be characterized by that the container inner and container outer walls 9,10 delimiting it in their shape are similar and both have approximately the shape of a U, but with the inner wall of the container has a smaller diameter and a smaller axial length than the container outer wall; the two walls 9, 10 are arranged coaxially to one another. Technically lets This arrangement can be realized particularly easily by having two different Size, but similar Containers with shape under preservation an axial and radial intermediate space (cavity 11) inserted coaxially into one another.

In the interior of the cavity 11, two are spatially separated from one another housed externally connectable reagents that react with each other in the brought together state giving off heat. According to Figql the second 13 of the reagents is filled directly into the cavity 11, wherein they located in the bottom wall cavity portion 14 and partially the cavity section 14 'located in the side wall 2 fills. At the inside of the cavity 11 is also a separation chamber 15 in the form of a reagent container 16 housed, in which the first reagent 17 is contained.

According to FIG. 1, the reagent container 16 in the cavity section 14 'is the Side wall 2 provided, both the contents of the reagent container 16 as the reagent container 16 itself is also spatially separated from the second reagent 13 are. Another embodiment, not shown, provides that the reagent container 16 embedded in the second reagent 13 located in the cavity and from this at least is partially surrounded (not shown).

Still referring to Fig. 1, the cavity section 14 ' arranged reagent container 16 on one of the facing into the interior of the cavity 11 Inner surfaces of the container inner resp.

-external wall set. In the exemplary embodiment is the reagent container 16 glued or welded to the inner surface 18 of the container outer wall 10.

With the reagent container 16, a pull cord 22 is firmly connected, which is passed through an opening 23 in the side wall 2 to the outside. As special The opening 23 in the end wall 24 of the container end edge has proven advantageous 4 excepted. The rip cord 22 is preferably glued to the reagent container 16 or welded on, which reagent container is expediently a foil pouch, which on the one hand receives the contained reagent 17 in a completely sealed manner and on the other hand is easy to tear by pulling on the pull cord 22 without great effort. The reagent container can be opened from the outside by pulling the pull cord 22 16 can be made by simply destroying it by tearing it.

Another embodiment of the disposable container according to the invention provides for the reagent container 16 to be loose when it is firmly connected to the pull cord 22 to be accommodated in the cavity 11, as shown in FIG. A tear of the reagent container 16 is then carried out by pulling the pull cord 22 in contact with the inner surface 25 of the end wall 24 pointing into the cavity 11 device and is destroyed with further pull on the pull cord 22. Appropriately carries the rip cord 22 according to FIG.

1 at its outwardly guided free end 27 a holding body 26, which on the one hand facilitates pulling on the pull cord 22 and on the other hand an accidental one The rip cord 22 does not slip into the cavity 11. Another possibility, the Securing the rip cord against slipping in exists, as in Fig.

3 shown therein, the rip cord 22 in the region of its free end 27 to be glued to the surface of the cover 8, for example.

The disposable container according to the invention is preferably made of two materials produced, the container outer wall 10 made of plastic material and the container inner wall 9 made of a material that conducts heat well, e.g. aluminum material such as aluminum foil, consists. To manufacture the disposable container, the first step is to use this structure Cup-shaped container outer wall 10 produced and according to FIG. 2 in the region of the container front edge 4 bent radially inward, so that a radial, in the direction of the receiving space 6 pointing annular projection 28 is formed. Now is in this from the container outer wall 10 quasi-formed "outer cup" is filled with the second reagent 13 and the reagent container 16 introduced with the rip cord 22. The rip cord is through a hole provided 23 (Fig. 3) outwards. Then it is made of thermally conductive material existing container inner wall 9 used, these at their free edge area 29 in the direction of the container outer wall 10, radially outwards with formation an annular projection 30 is kinked. The two ring projections 28,30 advised in the assembled state of the two container walls 9, 10 in contact with one another and are glued or welded to one another at this point (at 31).

Of course, the disposable container can also be made entirely of plastic material exist, making it a particularly inexpensive one Manufacturing can be carried out.

The following is the mode of operation of the disposable container according to the invention are explained in more detail: in the one in Fig. 1 in the cavity section 14 'of the side wall 2 arranged reagent container 16 contains the first reagent, which consists of a Reactant, a solvent for the reactant and one in the solvent also detachable foaming agent consists. The preferred reactant is Glycerin, water as a solvent and saponin as a foaming agent. These three components are mixed as a liquid.

The second reagent 13, which is housed directly in the cavity 11 itself contains an oxidizing agent that interacts with the reactant mentioned above Heat emission can react (exothermic oxidation), preferably potassium permanganate, and as a further component a passive agent that does not react with the oxidizing agent, preferably fumed silica.

The second reagent is in the form of a powdery substance.

If the rip cord 22 is now pulled, the burning chamber opens 15 or the reagent container 16 and the liquid first reagent 17 overflows the powdery second reagent 13 so that a reaction takes place as follows can: the reactant, e.g. glycerine, is replaced by the oxidizing agent, e.g. potassium permanganate, oxidizes with the release of heat, in the present example to brownstone. The initiation of this reaction takes place automatically without external heat input.

During this reaction a gas, e.g. carbon dioxide, is produced, which reacts with the Foaming agent, e.g. saponin, forms a foam. The gas is bound on the one hand, so that outwardly hardly any gas evolution can be registered, on the other hand However, the foam is distributed in the cavity 11 and even rises in the cavity section 14 'of the side wall high. This causes the heat of reaction stored in the foam the above-mentioned reaction from the side and from below to that in the recording room 6 The liquid contained 7 acts and heats it up very quickly.

This is particularly advantageous if the inner wall of the container 9 is made of highly thermally conductive material, e.g.

Aluminum material. The heat transfer can be done without any noticeable heat loss take place. Another advantage of foam formation is the insulating effect of the Foam when it has cooled. The heat then stored in the liquid 7 is prevented from penetrating the container outer wall 10. This has the consequence that on the one hand the liquid is prevented from rapidly cooling and on the other hand the container can be gripped safely without the risk of burns.

The main warming takes place through the resulting brownstone, the is in a solid aggregate state. The ferocity of the reaction, i.e. the The rate at which the reaction takes place and the time within which the resulting amount of heat is released can be controlled depending on how strongly the reactant through the solvent and the oxidizing agent the passive agent is diluted. This is how the response time is in the present example delayed by increasing the amount of water added to the glycerin.

The passive agent is used to dilute the oxidizing agent (Silicon dioxide) on top of that, the liquid components formed during the reaction, including water, to bind and absorb. This is especially important because of leakage the end products avoided following the use of the container according to the invention shall be.

With regard to the severity of the reaction, it remains to be added that; the The amount of heat released remains almost constant regardless of the "dilution rate". It can be reduced by choosing the mixing ratio between oxidation and reactants and by the absolute amount of this mixture. So will be preferable the mixing ratio is optimally "adjusted", i.e. for optimal specific heat output, and depending on the amount of liquid to be heated such as soup or the like.

the absolute amount of reagents chosen.

For an optimal and particularly effective reaction, a Mixing ratio of 30 parts of potassium permanganate, 30 parts of highly dispersed silicon dioxide, 30 parts of glycerin and 10 parts of water including 0.5 parts of saponin as special proved beneficial.

The resulting end product is neither toxicologically nor otherwise questionable, so that there is no environmental hazard.

The liquid 7 contained in the receiving space 6 is heated very quickly and, above all, much faster than when using conventional ones Heating methods, e.g. by means of an electric heating plate. This is how the Brownstone, for example, with the above proportions within 15 seconds a final temperature of 70 ° C to 80 ° C.

The cup according to the invention is advantageously very inexpensive manufacturable, so that the price increase compared to comparable conventional Cups without "integrated heating" are in the range of penny amounts.

It should be added that the shape of the disposable container according to the invention is of course not limited to that of the exemplary embodiment, rather all imaginable forms are possible. The size of the container is also variable; according to the volume of its receiving space 6, the required amount of Reagents selected.

Of course, the disposable cup according to the invention can also be used can be drunk directly, so it is not only used as a "heating container". For this it would be conceivable to reduce the thickness of the front edge of the container and make a bite-sized one Make shaping.

Another expedient development of the invention provides that the two reacting reagents 13, 17 75 parts of copper oxide, 25 parts fine grain aluminum, 1 part silicon dioxide and 0.01 part turkey red oil, the with cc. Sodium chloride solution is wetted contain. Preferably these are turkey red oil and the salt water solution in the reagent container 16 and the solid components (CuO, Al, SiO2) was added to the cavity 11. With this composition also results a very good heat development, so when mixed already occur after approx. 15 seconds about 1000 C.

The resulting end product is toxicologically harmless.
