DOUBLE SEAL SYSTEM FOR USE WITH PROBE Russian patent published in 2015 - IPC B65D47/00 

FIELD: machine building.

SUBSTANCE: double seal system (20) is made for use with probe (21) to ensure access to the internal space (34) from the outside environment (32). The system (20) contains a casing (22) creating a channel (24) passing along the longitudinal axis (26) between an outside end (28) of the casing and an internal end (30) of the casing to ensure connection between the outside environment (32) and internal space (34); a first flexible element (40) permitting insertion in it and passing across the channel in the first position along the axis, at that the first permitting insertion element is made with possibility to create seal around the probe, when the probe is inserted in it; and a second resilient element (42) permitting insertion in it and passing across the channel at the second position along the axis, at distance in the direction towards the internal end from the first position, at that the second permitting insertion element is made with possibility to make seal after the probe insertion though it, and when the probe is removed from the second permeable element.

EFFECT: higher seal efficiency.
