AN ENCLOSING STRUCTURE FOR CONTAINER PACKAGING MACHINES AND/OR MACHINE UNITS, IN PARTICULAR CAPPING MACHINES.

摘要

A packaging machine or machine unit, as used in particular for capping containers (5), is enclosed by a structure (1) that comprises a casing (2) positioned at least in part around the active components (3) of a packaging unit (4) supplied with open containers (5). The casing (2) comprises a fixed cowl (13) encompassing the components (3) of the packaging unit (4), and a movable cowl (23) furnished with at least one sealing element (4). The movable cowl (23) is capable of movement between an open configuration, in which a gap (23a) is created between the fixed cowl (13) and the movable cowl (23) so as to place the fixed cowl (13) in fluid communication with the surrounding atmosphere, and a closed configuration in which the sealing element (24) of the movable cowl (23) engages the fixed cowl (13), occluding the gap (23 a) and consequently isolating the interior of the fixed cowl (13) from the surrounding atmosphere.
