Description

[0001] The invention relates to a container attachment with a container lid provided with a lid top and a lid bottom, a pressurized gas line extending through the container lid, which has a pressurized gas inlet opening on the lid top side and a pressurized gas outlet opening on the lid bottom side, a liquid line extending through the container lid, which has a liquid outlet opening on the lid top side and a liquid inlet opening on the lid bottom side, a shut-off valve connected in the liquid line and a shut-off valve actuating element mounted on the container lid, by means of which the shut-off valve can be actuated.

[0002] Such a container attachment can be placed on the opening of a liquid-filled container, such as a drinking bottle, and secured with its lid. If a gas capsule filled with pressurized gas is then connected to the pressurized gas inlet, gas flows into the interior of the liquid container. This gas, when the shut-off valve is open, can be used to force the liquid through the liquid line, causing it to flow out of the outlet. The pressurized gas thus acts as a propellant for the liquid. The liquid exiting the outlet can then be poured, for example, into a drinking vessel or directly into the user's mouth. If a neutral-tasting liquid, such as water, is used, there is often a desire to flavor it.However, this requires choosing a single flavor for the entire contents of the liquid container. Furthermore, there is the problem that traces of the flavoring remain on the inner wall of the container after it has been emptied, potentially pre-flavoring subsequent liquid fillings, which is generally undesirable. Another issue is that introducing flavoring into the liquid container by a user can contaminate the liquid with germs, causing it to spoil prematurely.

[0003] Based on this, the invention is primarily aimed at creating a way of flavoring a liquid taken from a liquid container while avoiding at least one of the aforementioned disadvantages.

[0004] This problem is solved according to the invention with a container attachment according to claim 1 and with a liquid container having such a container attachment according to claim 11. Preferred embodiments of the invention are given in the dependent claims and in the following description.

[0005] A container attachment comprising a container lid provided with a lid top and a lid bottom, a pressurized gas line extending through the container lid, which has a pressurized gas inlet opening on the lid top side and a pressurized gas outlet opening on the lid bottom side, a liquid line extending through the container lid, which has a liquid outlet opening on the lid top side and a liquid inlet opening on the lid bottom side, a shut-off valve connected in the liquid line, and a shut-off valve actuating element mounted on the container lid by means of which the shut-off valve can be actuated, is further developed according to the invention in particular by an aroma capsule detachably connectable and / or connected to the container lid on the lid top side, which has a capsule outlet opening,comprising a capsule inlet opening and a capsule interior connecting these capsule openings, wherein the capsule inlet opening is connected to the liquid outlet opening in the aroma capsule in the state of being connected to the container lid.

[0006] If a flavoring agent is introduced into the interior of the aroma capsule, a liquid flowing from the capsule inlet opening through the capsule interior to the capsule outlet opening can be flavored with the flavoring agent. If this liquid is drawn from a liquid container using the container attachment, the liquid is not flavored inside the container, but rather outside of it, by means of the aroma capsule. Since the aroma capsule is detachably connected to the container lid, it can be replaced by another aroma capsule, particularly one of identical design, with a different flavoring agent or without a flavoring agent. Thus, the flavor can be varied without changing the liquid in the container.Furthermore, the aroma capsule is positioned downstream of the shut-off valve in the direction of liquid flow, preventing any liquid from flowing back from the aroma capsule into the liquid container when the valve is closed. This prevents or at least significantly reduces the introduction of germs into the liquid container via the aroma capsule.
