Description

Container for holding a liquid

The present invention relates to a container for holding a liquid.

Containers for holding liquids are basically known in various embodiments. They are used in many areas, for example both in the commercial and private environment, such as in the household, to absorb liquids, at least temporarily. They are also used as drinking containers.

A conventional container is in terms of its functional structure of only a single chamber, which serves both for the storage and for the removal of the liquid contained.

If you fill in the container in particular a hot or very warm liquid, it is distributed in it and has substantially the same temperature or cools this depending on the material on the ground and on the vessel walls and collects density mainly on the ground. When removed, e.g. Drinking, the fluid from above is therefore always taken from the hottest part first. In order to remove the liquid at a desired temperature or in such a temperature range, which is lower than the filling temperature, so a certain waiting time must be taken into account, during which the entire liquid cools evenly.

Accelerated cooling can be achieved by actively cooling or stirring, eg with a spoon, or by introducing a heat (ab) conductive article, eg a metal spoon. However, these methods are expensive or not very efficient. Also, for example, the spoon must be removed before drinking, as it would interfere with drinking. In addition, because of the single chamber, the liquid in the container cools down equally everywhere, so that it initially takes a long time to reach a desired temperature. When this is finally achieved, the liquid continues to cool rapidly and soon reaches a possibly too low temperature.

The object of the invention is to improve a container to the effect that as quickly as possible after filling over as long a period as possible, the liquid in it can be removed at a desired temperature.

The solution of this object is achieved by a device having the features of claim 1.

According to the invention, the container has a partition wall extending between two wall sections, which is designed to divide the container into at least one removal and one storage chamber, the chambers being connected or connectable to one another at least at a lower region ,

The partition wall preferably connects directly to the wall. In particular, the dividing wall can be integrally formed with the wall or attached to the wall as a separate component.

Alternatively, the container comprises a thick-walled, at least partially closed partition which is designed to divide the container into at least one withdrawal and one storage chamber, the chambers being devoid of at least, in particular exclusively, are interconnected or connectable at a lower area. The partition may be formed for example as a thick-walled pipe. The closed partition may in particular be arranged centrally in the container. Preferably, this does not protrude down to the ground. Alternatively, this may protrude to the bottom and have one or more recesses in the region of the bottom.

The interior of the container is divided by the partition wall, preferably exactly, into a removal chamber and a storage chamber. However, it would also be conceivable to subdivide the container into more than two chambers.

The partition may be straight or curved, e.g. curved or undulating, extending between the wall sections. Also, the closed partition may have a curved outer surface. By a curved shape of the partition, the area can be increased and thus the heat absorption capacity of the partition can be improved.

The removal region is the divided region which is used to remove, in particular to drink, the liquid contained in the container.

In contrast, the storage chamber serves as a reservoir for the liquid. The storage chamber may preferably receive a larger amount of liquid than the removal chamber.

A filling of the container with a liquid preferably takes place via the storage chamber. However, the container can alternatively or additionally be filled via the removal chamber. Due to the connection between the two chambers, an exchange of the liquid from the storage to the removal chamber takes place. If liquid is removed from the extraction chamber, then liquid from the storage chamber flows into the extraction chamber. The level is thus always the same in both chambers, comparable to communicating tubes.

In order to be able to remove the liquid from the container, in particular to drink it, it can, at least in the area of the extraction chamber, be open or otherwise open at the top or otherwise, e.g. through a drinking straw, be guided to the outside. In a preferred embodiment, removal chamber and storage chamber are open at the top. The container may also have a lid which at least partially closes the top. An opening may in this case also be provided, for example, in the form of a drinking nozzle. The container may be a drinking container, for example a cup, a glass or a cup, in particular a thermo mug, but also a bottle, e.g. for baby food, which may have none, one or more handles or handles. A handle is preferably located on the outside in the region of the storage chamber. The removal region can be arranged in a region perpendicular to the handle. This allows for an optimal drinking position.

The container may be formed of a refractory material, such as porcelain, ceramic, glass, plastic, wood, metal and / or cardboard. The liquid may be, for example, a hot beverage, for example tea, coffee, cocoa, milk or mulled wine, a hot dish, for example soup, or industrially processed liquids, for example water. In industry, the container according to the invention can be used in all applications in which a liquid with a suitable temperature is to be removed over as long a period as possible. The material of the container, in particular also the partition, can, for example, depending on the heat capacity of the liquid, for example a specific heat capacity of at least 1.0 J / (gK), in particular of at least 1.5 J / (gK), preferably of at least 1 , 7 J / (gK). The cooling takes place mainly via the temperature delivery to the container material. Especially in the initial phase, in particular within the first minute or the first two, three, four or five minutes after filling, the container material, so for example, the material of the outer wall, the container bottom and / or the partition, therefore, the heat and saves these. Until the optimum drinking temperature is reached in the sampling chamber, the cooling is thus mainly due to the temperature output to the container material. In particular, a cool withdrawal channel forms up to a cooler liquid region. The cooler liquid accumulates in particular at the bottom of the storage chamber. The heat capacity of the container material depends, in addition to its volume, in particular on its specific heat capacity, its density and temperature, in particular before filling the container.

The container material may for example have a heat capacity of at least 1.0 J / (cm ³ K), in particular of at least 1.5 J / (cm ³ K), preferably of at least 1.7 J / (cm ³ K). The cooling can be done because of this value in conjunction with the associated volume of container material via the temperature output to the container material. The density can, for example, at least 0.9 g / cm ^3, preferably at least 1, be 1 g / cm ^3. The heat capacity is thereby maximized or optimized at a given container material thickness for heat absorption. By choosing the material with a certain specific heat capacity, the cooling strength and thus also the range of the desired temperature can be controlled. By contrast, the cooling rate of the material can be adjusted via the thermal conductivity of the material.

The container wall, so the outer wall, the container bottom and / or the partition can be relatively thick. Thus, the thickness may be at least 2 mm, preferably at least 4 mm or 5 mm. In the sampling chamber, the cross-sectional area for the liquid can be kept as small as possible, however, the cross-sectional area of the material surrounding the sampling chamber as large as possible, i. thick-walled. If the thickness of the material is greater, the specific heat capacity may be correspondingly lower and vice versa. Both parameters can also be maximized. The desired properties of the container can consequently be achieved in different ways.

The effect (cooling) of a wall as thick as possible and at the same time of the smallest possible cross-sectional area in the removal chamber can be enhanced, in particular, by an additional component which is inserted into the removal chamber. Through this component, an additional heat absorber and / or storage can be introduced into the removal chamber. At the same time, the volume of liquid to be cooled is reduced. The filled liquid may in particular be in a very hot range, for example more than 60 ° C or 80 ° C. The immediate ingestion of hot liquids can be unhealthy for the human body. A lowering of the temperature by heat release according to the invention container leads to a drinking or consumption temperature of approx. 50 ° C, which is considered ideal, and can thus help the user to permanently reduce the risk of damage to health. In the container according to the invention, the liquid in the extraction chamber cools faster than in the storage chamber. In the removal chamber thus a desired discharge temperature is thus achieved comparatively quickly, while the storage chamber keeps the temperature of the liquid at a higher level. Especially in the central area of the storage chamber, the temperature remains high. On the underside, the liquid cools by dissipating heat and on the container bottom more strongly. Also, the warm liquid rises, so collects at the bottom of a comparatively cool liquid. By contrast, the cooler liquid, in particular at the edge, sinks in the storage chamber.

Because the extraction chamber and the storage chamber are connected to one another in a lower region, the cooler liquid first flows from the storage chamber into the extraction chamber from the bottom and can be removed immediately or at least earlier. It may also be provided a Verschließme- mechanism through which the chambers can be connected or disconnected if necessary.

The fact that the temperature in the central region of the storage chamber remains at a higher level, the heat over a longer period is stored, so that the liquid does not cool down so quickly after reaching a desired temperature and remains in the desired range longer.

Further developments of the invention can be found in the dependent claims, the description and the accompanying drawings. According to one embodiment, the container is designed such that the ratio of the outer surface to the volume of the removal chamber is greater than the ratio of the outer surface to the volume of the storage chamber. The outer surface of the sampling chamber is composed of the removal section outwardly bounding wall portion and possibly bottom portion of the container together, so all surfaces that are in contact with the environment. On the other hand, the dividing wall does not count toward the outer surface, since it is adjacent to the storage chamber and not to the surroundings. The partition serves as an insulator or as an additional heat absorber and / or heat storage between the extraction chamber and the storage chamber. The volume of the sampling chamber corresponds to the space available to a liquid to be picked up or taken up in the sampling chamber. Correspondingly, the outer surface of the storage chamber is composed of the wall section delimiting the storage chamber to the outside and optionally the bottom section of the container. The volume of the storage chamber corresponds to the space available to a liquid to be taken up or taken up in the storage chamber.

These external surfaces allow a temperature exchange with the environment. The liquid in the container releases temperature to the container wall and also to the outside, which leads to a decrease in the temperature of the liquid in the container.

Due to the larger ratio of the outer surface to the volume in the extraction chamber in relation to the storage chamber, the liquid in the extraction chamber is relatively more temperature. The liquid contained in the storage chamber has due to the relatively smaller outer surface a higher temperature. If liquid flows out of the storage chamber after removal of the more rapidly cooled liquid from the removal chamber, then this liquid that has flowed after also cools more quickly in the removal chamber. This leads, for example, that a hot drink can be drunk faster. This reduces the risk of burns and / or scalds.

Alternatively or additionally, the outer surface of the removal chamber may have a greater thermal conductivity and / or greater specific heat capacity than the outer surface of the storage chamber. The container may thus have, for example, different materials and / or different material thicknesses. The liquid can thus cool faster in the removal chamber than in the storage chamber. According to a further embodiment, the container is designed such that the ratio of the boundary surfaces to the volume of the extraction chamber is greater than the ratio of the boundary surfaces to the volume of the storage chamber. The boundary surfaces of the removal chamber are all surfaces that limit the removal chamber, ie in particular the outer surface of the removal chamber, optionally with bottom portion of the container, and the partition. In a thick-walled, at least partially closed partition wall, the partition itself forms the boundary surface.

Accordingly, the boundary surfaces of the storage chamber all surfaces that limit the storage chamber, ie in particular the outer surface of the storage chamber, optionally with bottom portion of the container, and the partition. Because the ratio of the boundary surfaces to the volume of the removal chamber is greater than the ratio of the boundary surfaces to the volume of the storage chamber, relatively more heat can be released to the boundary surface in the removal chamber than in the storage chamber. The liquid in the extraction chamber thus cools faster and faster than in the storage chamber.

According to a further embodiment, the volume of the extraction chamber is smaller than the volume of the storage chamber. Because the withdrawal chamber has a smaller volume than the storage chamber, the liquid present in the removal chamber can cool more quickly than in the larger storage chamber. With a removal of liquid from the removal chamber flows from the larger storage chamber liquid in this after and can in turn cool faster in the smaller removal chamber.

According to one embodiment, the container is designed so that the volume of the removal chamber is at most a third, a quarter or a fifth of the volume of the storage chamber. The removal chamber is thus significantly smaller than the storage chamber.

According to a further embodiment, at least part of the partition wall does not extend to the container bottom. In this way creates a passage in the lower part of the container. In this case, the dividing wall may, for example, be shorter overall than the cup wall or have one or more recesses, in particular a centrally arranged recess, in the region of the bottom.

According to one embodiment, the dividing wall, in particular convex, is bent. The partition does not extend on the shortest path between the wall areas. With regard to the outer wall of the sampling chamber, In particular, the dividing wall extends convexly from the outer wall into the container. In a plan view of the removal chamber, this leads to a substantially elliptical or ship-shaped surface. In this way, the removal, in particular the drinking, of the liquid in the removal chamber is particularly simple. Alternatively, the partition may also be concavely bent. In this way, the ratio of outer surface to volume is further optimized.

According to a further embodiment, the cross section and thus the volume of the extraction chamber decreases from top to bottom. In the removal chamber, the distance between the outer wall and the partition in the upper area is greater than in the area of the floor. The removal chamber tapers, in particular funnel-shaped, from top to bottom. Accordingly, the cross section and thus the volume of the storage chamber can increase from top to bottom.

Since the extraction chamber thus has a larger cross-sectional area in the upper region, the evaporative cooling responds relative to the volume below it.

The invention will now be described by way of example with reference to the drawings. Show it:

1A is a perspective view of an embodiment of a container according to the invention,

Fig. 1 B further perspective view of the container of FIG. 1A _;

Fig. 2 is a sectional view of the container, and 3A to 3E are schematic sectional views of an embodiment of a container according to the invention.

First, it should be noted that the illustrated embodiments are purely exemplary in nature. In particular, the partition may be configured as desired, for example, straight, curved, bent or extend in any other form between the two wall sections. Alternatively, the partition may be formed as a thick-walled, at least partially closed partition. Furthermore, the container may have no or more than one handle or handle. The recess may extend over the entire underside of the partition wall, be larger or smaller or have a different shape. In addition, one or more smaller recesses in the area of the floor would be conceivable. Furthermore, the funnel-shaped removal chamber can also have a different, for example, stepped, shape.

1 A and 1 B each show a perspective, slightly oblique view of the container from above. The container comprises an outer wall 10, a container bottom 11 and a handle 12. A partition wall 14 extends between a first wall section 16 and a second wall section 16 'and divides the cup into a removal chamber 18 and a storage chamber 20. The chambers 18, 20 are connected to one another via a substantially rectangular recess 22 on the bottom 1 1.

As can be seen in FIG. 1A, the cross section of the removal chamber 18 is semicircular in the upper region. Towards the bottom, the removal chamber 18 tapers in a funnel shape, which can be seen in FIG. 1B.

Fig. 2 shows a sectional view of the container. Recognizable here is the recess 22 in the partition wall 14. The partition wall 14 may be from the outer wall of the removal mekammer 18 convex in the direction of storage chamber 20 to be curved. Alternatively, the partition wall 14 may also be concavely curved or straight as shown in Figs. 1A and 1B. FIGS. 3A to 3E show various stages with and without liquid 30.

In the sectional view of FIG. 3A, there is no liquid in the container. The partition wall 14 does not extend in a partial area to the bottom 1 1 of the container, so that a connection between the storage chamber 20 and the smaller removal chamber 18 is made.

In Fig. 3B, the container is filled with a hot liquid 30. The liquid 30 initially has the same temperature everywhere after filling. As can be seen in FIG. 3C, the liquid 30 in the extraction chamber 18 cools faster than in the storage chamber 20. In the storage chamber 20, a central region 32 with an elevated temperature remains. Since the liquid 30 is cooled in the removal chamber 18 to a desired temperature, it can be drunk easily.

As can be seen in FIG. 3D, liquid 30 was removed from the inclined container 18 from the removal chamber 18. The liquid 30 now flows, as indicated by the arrow, out of the storage chamber 20 into the removal chamber 18 and cools there to a desired temperature. In the central area 32, by contrast, the hot liquid 30 is stored over a longer period of time so that the liquid 30 does not cool down too quickly overall when the desired temperature has been reached. After a certain time, as shown in Fig. 3E, no central area 32 more available, ie the liquid 30 is cooled and thus can be drunk altogether. According to the invention, the liquid cools faster in the removal chamber, so that they can be removed faster, for example, drunk, can be.
