Description

The invention relates to a container for liquids, in particular a beverage can, according to the preamble of patent claim 1.

There are containers, for example, beverage cans known, which are filled with only a single liquid, so for example a finished mixed drink. It may be necessary to freshly prepare a mixed beverage, for example a cocktail, of two components, for example an alcoholic component and a non-alcoholic component, without the need for additional vessels.

The DE 201 07 738 U1 , the AT 30 226 E and the DE 297 04 521 U1 each show a container for liquids. All of these containers have a substantially cylindrical body which encloses a first receiving space for a liquid, which is in fluid communication with a second receiving space for a further liquid. If the fluid connection between the two receiving chambers is produced in these known containers, the liquid from the second receiving chamber enters the first receiving chamber and initially mixes there in the central core region of the first receiving chamber with the first liquid contained therein. In order to produce a mixture of the two liquids, it is necessary to shake the container for a long time in all directions, with a uniform mixing is not always guaranteed especially for liquids of different specific gravity.

The US 2009/0311389 A1 discloses container pairings each comprising a container for cereals and a container for milk, wherein the two containers of each pair of containers are screwed together. In the area of the screw connection, the container pairing has a smaller diameter than in the upper and lower region of the container pairing. The lower container is provided for receiving the milk and the upper container receives the cereals. In the area of the container connection, the lower container has a removable membrane, so that after removal of the membrane and the screwing together of the two containers of each container pairing a fluid connection between the two containers is made.

The DE 297 12 783 U1 discloses a beverage can with a concertina folded peripheral wall. The purpose of this embodiment is that the beverage can after squeezing can be compressed by upsetting the accordion-like peripheral wall to a minimum.

The DE 690 24 971 T2 discloses a container for carbonated beverages, wherein the container is cylindrical in all embodiments shown there. In an embodiment shown there, a double cone shaped insert is provided for the container which is inserted into the interior of the cylindrical container. This insert is filled with a gas under a predetermined pressure and serves to occupy a first volume in the container interior in a first state of the fluid filled in the container. If the fluid present in the container expands and thereby generates an internal container pressure which is greater than the pressure of the gas in the double-cone-shaped insert, the double-cone-shaped insert-like an accordion-is folded together and thereby occupies only a smaller partial volume in the container interior. However, the container itself retains its original cylindrical shape.

The DE 196 41 732 A1 discloses a substantially cylindrical container provided slightly below its center with a constricted portion similar to a bellows. This section is intended to provide a larger volume for the container interior with an increase in the pressure difference between the container internal pressure and the surrounding pressure by radial deformation.

From the DE 34 24 936 A1 a container for mixing of liquids is known, the single receiving space has two referred to as vortex projections in the vertical direction and facing each other local indentations, by which a good and quick mixing is to be achieved.

It is therefore an object of the present invention to provide a generic container for liquids, which makes it possible to pre-portioned a liquid mixture consisting of two liquid components as needed in a simple and fast way and to make ready for use.

This object is achieved by the feature specified in the characterizing part of claim 1.

The invention accordingly relates to a container for liquids, in particular a beverage can, having a body which has a first receiving space for a liquid enclosed by a first wall, wherein the first wall has an outlet opening for the liquid, which is closed by a closing device, wherein the first receiving space with a second receiving space enclosed by a second wall for a further liquid in Fluid connection can be brought to mix the two liquids together. According to the invention, it is provided that the body is designed in the form of a rotational body which is constricted in the region of the center in the manner of a double cone, whereby the first receiving space is constricted.

This container has the advantage that it can accommodate two pre-portioned in a predetermined ratio liquids separated from each other. After establishing the fluid connection, these can then be mixed quickly and effectively directly in the container and the liquid mixture can be dispensed through the outlet opening.

Further advantageous embodiments are specified in the subclaims.

Advantageously, the second receiving space enclosed by the second wall is formed integrally in the container.

In an alternative embodiment, the second receiving space enclosed by the second wall is provided in an auxiliary container formed separately by the container, which can be mechanically connected to the container. This makes it possible, by simply combining already pre-filled container and auxiliary container to assemble different fluid combinations, which can then be mixed together if necessary.

Preferably, the fluid connection between the first receiving space and the second receiving space by rotation of an actuating element which is provided on the container or on the auxiliary container can be produced. This embodiment allows a quick opening of the fluid connection.

It is advantageous if the actuating element acts on a valve mechanism which connects the two receiving spaces with one another in the opened valve state.

In this case, the valve mechanism preferably has at least two intermediate wall elements which are provided at least one opening and which abut one another in a sealing manner but which are movable relative to one another, in particular rotatable or displaceable, such that the openings are at least partially overlapping one another Position can be brought together to form at least one passage opening to create the fluid connection between the two receiving spaces.

In an alternative embodiment according to the invention, the actuating element acts on a penetration mechanism which, in the actuated state, penetrates at least one membrane wall separating the two receiving spaces from one another. This variant has the advantage of a simple and inexpensive construction.

Preferably, the penetration mechanism has at least one fluid connection channel, which opens in the actuated state of the penetration mechanism 'with its first end into the first receiving space and opens with its second end into the second receiving space. In this way, after the penetration of the membrane wall, a fluid exchange between the two receiving spaces can be reliably effected in order to mix the liquids quickly and effectively, in particular if more than one fluid connection channel is provided. For this purpose, the penetration mechanism, for example, have a plurality of penetrators, each having such a fluid communication channel.

In another preferred embodiment, the actuator is configured to act on an action mechanism that applies a force such as a tensile force, a compressive force, a shear force, and / or moment to a membrane wall separating the two receiving spaces, and thereby the Destroys the membrane or changes its position in such a way that its two separating spaces cancel each other out. By means of the action mechanism, for example, the membrane is torn open to establish the fluid connection. For this purpose, the membrane wall can be provided with the membrane only in one region, for example in the center, or the membrane wall can be completely formed by the membrane.

The actuating element is preferably formed by a first slewing ring provided on the container, preferably arranged on the end of the container facing away from the closure device. Thus, the fluid connection can be made without additional tools, namely only by simply turning the turntable.

It is also advantageous if the closure device is formed by a lid which can be rotated to open and close the outlet opening of the first receiving space and which preferably has a second revolving ring. The lid can be configured for example as a screw cap or provided with a bayonet closure. The container can be sealed again after only partial removal of the liquid.

The rotatable lid is attached or attachable to the container so as to be rotatable to close the outlet opening in a direction opposite to the direction of rotation into which the first turntable for establishing the fluid connection is to be rotated between the two receiving spaces, it is safely prevented that in the manufacture of the fluid connection unintentionally, the lid is opened above the outlet opening. Thus, when establishing the fluid connection, no liquid can accidentally escape from the container.
