Description

Technical area

[0001] The present invention relates to a container for filtering liquids according to the preamble of patent claim 1. State of the art

[0002] There are various products on the market that include a water bottle with an integrated filter medium. The filtering effect is achieved, for example, by pressing a container with an attached filter medium into a container filled with contaminated water. Another variant is to filter the water by sucking the contaminated water through a filter medium attached to the mouthpiece of the bottle. Products with the additional option of treating the water with pads containing flavor and / or nutrients are not yet known.

[0003] Furthermore, special containers for filtering liquids are known from the prior art, which are equipped with a first chamber for receiving an unfiltered liquid and with a second chamber for receiving a filtrate filtered from the unfiltered liquid, wherein a filter element is arranged between the two chambers, by means of which the liquid introduced into the lower second chamber can be filtered towards the first chamber.

[0004] Known containers, which are generally referred to as so-called “outdoor water filter bottles”, comprise a base part on the second chamber and a cylinder wall, wherein the filter element is arranged between the two chambers on the container, which separates the two liquid chambers from each other in a filtering manner, wherein the base part of the second chamber is received on the container in such a way that it can move with respect to the filter element that the volume of the second chamber is reduced by moving the base part in the direction of the filter element and thus the liquid flows from the second chamber through the filter element into the first chamber.

[0005] The disadvantage of these solutions is that, due to their technical design, contaminated water sometimes escapes unfiltered, and a satisfactory filtering result can often only be achieved with considerable force. Other known solutions (e.g., suction) produce inadequate filtering results, merely improving the taste and odor without filtering out bacteria and germs. No known water filter bottle currently features a system for enriching the filtered water, as described above. Description of the invention

[0006] The object of the present invention is to eliminate the aforementioned disadvantages and to create a mobile container for filtering liquids, which ensures a controlled water flow through the filter medium and at the same time achieves a very good filtering result with less effort than known solutions.

[0007] According to the invention, the above object is achieved according to the preamble of claim 1 in conjunction with the characterizing features. Advantageous embodiments and further developments of the container according to the invention are specified in the dependent subclaims.

[0008] The water to be filtered is first poured into the lower, second, cylindrical, and deformable chamber, preferably on the outside of the container. The upper, first chamber, on the underside of which the advantageously replaceable filter element is located, can then be attached (e.g., screwed) to the second chamber. The second chamber is then compressed from top to bottom by manually applying force to the container, so that the water flows through the filter element directly into the first chamber and is filtered in the process.

[0009] The filter element used preferably combines mechanical filtration, electroadhesion, and ion exchange to capture particularly fine particles. The advantageous use of various metal fibers and activated carbon filters out bacteria and viruses, as well as unpleasant odors and flavors, from the water.

[0010] The lower chamber is preferably fixed in the compressed state so that it cannot expand again on its own after the filtering process. This is achieved both by the shape and stability of the cylindrical wall of the second chamber and by a preferred fastening mechanism on the base of the second chamber, which snaps into place on the underside of the container. The water is prevented from flowing back after the filtering process by the design-specific properties of the filter element. The pressure exerted on the water in the container by gravity alone is not sufficient to transport the water back through the filter element into the lower, second chamber of the container. Since the second chamber is compressed after the filtering process and the container - as described above - is preferably flush with the base, any backflow of the filtered water is impossible anyway.
