Abstract
The device is characterised in that the obturating means are constituted by an obturating screw (24) capable of co-operating with the whole set of mounting pieces (3) and, if required, with a ring-shaped obturating joint (25) and in that the capturing means are constituted by a threaded joining piece (25) to co-operate with the whole set of mounting pieces (3) by replacing the obturating screw (24) and, if required, the ring-shaped obturating joint (25) during the control, so as to break the imperviousness of the receiving cell (6) with respect to the container or box and comprising a perforation (34) linked to continuous analysing means so as to enable capture of the gas that has entered the receiving cell (6).
Claims27
A method of forming a sealed container from which gasses can be sampled without contaminating contents of the container, the method comprising the steps of:
- providing a lid member having an opening formed therein;
- providing a base member defining a control chamber;
- defining receiving and collecting portions of the control chamber by arranging a filter member within the control chamber, where the filter member is impermeable to pathogens but is permeable to gasses;
- providing a first sealing member;
- mounting the base member and first sealing member onto the lid member such that the first saling member forms a first seal between the lid member and the base member;
- mounting the lid member onto the container such that the first sealing member isolates an interior of the container from the receiving portion of the control chamber;
- processing the container to preserve the contents thereof;
- and
- moving the base member and the lid member relative to each other to disrupt the first seal between the lid member and the base member and thereby allow gasses within the container to flow into the receiving chamber, through the filter member, and into the collecting chamber for analysis.
A system for analyzing the contents of a hermetically sealed container to check the consumable nature of the contents of the container by collecting gases in the container without allowing micro-organisms into the container, the system comprising:
- a can body filled with consumable material;
- a lid having a lid opening formed therein, the lid being attached to the can body to form the hermetically sealed container;
- a base part attached to the lid to define a control chamber;
- a filtering membrane that divides the control chamber into receiving and collecting cells, where the filtering membrane is permeable to gases but impermeable to micro-organisms;
- a first seal member for preventing fluid from flowing between the interior of the container and the control chamber when the base part and lid are in a first configuration relative to each other and allowing fluid to flow between the interior of the container and the receiving cell of the control chamber when the base part and the lid are in a second configuration relative to each other;
- and
- a moving structure for moving at least one of the base part and the lid relative to at least one of the other of the base part and the lid such that the base part and the lid move between the first and second configurations.
