Abstract
The invention relates to an inert gas flow which is directed through a channel. The channel includes walls (19,21) which limit the flow. A container having a charging inlet is fed through a recess (10) which is arranged in the first wall (21) adjacent to the flow. According to the invention, the channel includes limiting structures for the flow which are arranged in the area opposite the recess and the first wall can be displaced in a parallel manner in relation to the limiting structures. The channel, together with the container, forms a closed inert gas rinsing chamber.
Claims8
A device for flushing at least one can with inert gas, comprising:
- an upper housing connected in a stationary manner to a table top and gripping around part of a top of an inner and outer edge of a perforated disc, said perforated disc being rotatable about an axis of rotation and arranged above a turnstile and coaxially therewith at a predetermined distance from the table top, wherein said perforated disc and turnstile are configured to execute the same rotational movements about said axis of rotation;
- a lifting device for lifting and lowering said can;
- and
- a channel bound by an upper wall formed by said stationary upper housing and a lower wall formed by said rotatable perforated disc, said channel having an inert gas feed pipe and a gas discharge pipe, wherein the lower wall has at least one passage through which a filling opening of the can can be introduced into the channel for the purpose of flushing, and wherein the lower wall can be moved parallel relative to the upper wall.
