The present disclosure relates to a liquid injecting container for storing liquid and injecting the liquid into a refillable device. The liquid injecting container includes a hollow housing, a sealing component, and a rotating body. The housing has an open end configured for connecting the refillable device. The sealing component and the rotating body are arranged in the open end. The rotating body is rotatable relative to the sealing component, the sealing component defines at least one liquid outlet, the rotating body is capable of rotating driven by the refillable device between a first position where the rotating body seals the at least one liquid outlet, and a second position where the at least one liquid outlet is opened, such that the liquid in the liquid injecting container can flow into the refillable device.

The invention relates to a method for refilling a bottle with liquid, in a system (10) comprising, vertically: a liquid refill (12) and a bottle (14) to be refilled, which is or are produced in the form of a manually deformable container, a device (16) for transferring liquid, arranged between the refill (12) and the bottle (14) and comprising two parts (18, 20), a first part (18) being attached to the refill (12),
the method comprising: rotating one part relative to the other part in order to bring them into a first rotational position in which they jointly define a passage for the liquid from the refill to the bottle, applying external pressure to a manually deformable container with a view to transferring liquid from the refill (12) to the bottle (14) through the liquid passage, rotating one part relative to the other into a second rotational position in which the passage of liquid is obstructed.
