Description

[0036] The invention will be explained in greater detail by the accompanying figures, in which:

[0037] FIG. 1 shows a drinking bottle according to the invention according to variant (a) in the largely empty state;

[0038] FIG. 2 shows a drinking bottle according to the invention according to variant (a) in the full state;

[0039] FIG. 3 shows a drinking bottle according to the invention according to variant (b); and

[0040] FIG. 4 shows a drinking bottle according to the invention according to variant (c).

[0041] FIG. 1 shows a drinking bottle according to the invention in the empty or unfilled state. The drinking bottle has a case 1 and a dome 2 with a valve 3 and is closed by an openable or removable cap 4. The cap 4 protects the sensitive valve 3 from damage and contamination.

[0042] The dome 2 is designed as a screw top (not shown). The valve 3 arranged in the dome 3 has a fluid-tight top and projects through the dome 2 into the interior of the drinking bottle.

[0043] Beneath the dome 2 there is a bag 5, which is designed as a bellows. In the illustrated state, the bag is empty and folded together. The upper edge of the bag 5 is formed by a sealing element 6, which seals with respect to the inside edge of the drinking bottle and the underside of the dome 2.

[0044] Beneath the bellows 5 there is a support element 7, which supports the bellows 5 on the underside. The support element 7 is itself supported by a helical spring 8, which in turn is arranged on the base 9 of the drinking bottle. The helical spring 8 is fully relaxed in the illustrated state and has compressed the bellows 5 more or less completely. The support element 7 and the helical spring 8 are advantageously integrally connected to one another. Alternatively, the support element 7 can also be fixedly connected to the bellows 5.

[0045] Position 11 denotes a guide element for the helical spring 8. Generally, two such guide elements 11 are required.

[0046] FIG. 2 shows the drinking bottle according to FIG. 1 in the full state. The bag/bellows 5 is filled and expanded over its full length, and the helical spring 8 is fully tensioned.

[0047] When fluid is taken from the bellows 5, the helical spring 8 compresses the bellows, in dependence on the fill level, and pushes it in the direction towards the valve 3.

[0048] In the embodiment illustrated, the cap 4 is fastened to the drinking bottle by means of a hinge 10 and can be opened. Not illustrated is a pressure equalisation valve arranged in the base region of the drinking bottle, which correspondingly serves to take fluid from the bellows 5 for pressure equalisation.

[0049] FIG. 3 shows a drinking bottle according to the invention according to variant (b). Unless indicated otherwise, the elements of the drinking bottle correspond to those of FIG. 1 or 2. The drinking bottle contains inserted stages 11, which are each at a defined distance from one another and are able to contain a defined amount of fluid. The stages are interconnected centrally by openings, at which flaps 12 are arranged, which flaps are closed when the bottle is stored horizontally but open when fluid is taken by tilting of the bottle, so that the drinking fluid is able to flow in the direction towards the valve. The inserted stages 11 in the insert 5 reliably prevent sloshing of the fluid when the drinking bottle is partially empty.

[0050] FIG. 4 shows a drinking bottle according to the invention according to variant (c). In this case, the insert 5 contains a filling 13 of a material forming honeycombs or cells, which can be formed integrally with the insert 5. A passage 14, which can serve, for example, to receive a drinking straw, runs centrally. The honeycombs or cells are interconnected, so that the drinking fluid is able to move between the honeycombs or cells. This variant also reliably prevents sloshing of the drinking fluid.
