Device and method for atmosphere modification in a container during the sealing process
A method for atmosphere modification in a container during the sealing process that includes deploying a closure head on the container so as to enclose at least the container-opening and create an air-tight seal such that an interior volume of the closure head is isolated from the ambient atmosphere. The closure head having at least one conduit providing fluid communication between the interior volume and at least one of a vacuum source and a pressure source. The method also includes creating at least a partial vacuum inside the container, inserting a replacement atmosphere into the container by means of the pressure source, sealing the container; and removing the closure head from the container. Devices for implementing this method are also disclosed.
1. A method for atmosphere modification in a filled container during the sealing process, the container having a container-opening for insertion and removal of contents of the container, the method comprising:
(a) attaching a sealing element on the container, the container being implemented as a rigid container, so as to close the container opening, said sealing element configured with at least two layers so as to provide a passageway having at least a first opening open to the interior region of the container and at least a second opening open to the outside of the container;
(b) deploying a closure head on the container so as to enclose at least said second opening, so as to create an air-tight seal such that an interior volume of said closure head is isolated from the ambient atmosphere, said closure head implemented so as to have at least one conduit in fluid communication between said interior volume and at least one of:
(A) a vacuum source;
(B) a pressure source;
(c) creating at least a partial vacuum inside the container,
(d) inserting a replacement atmosphere into the container by means of said pressure source;
(e) bonding together at least a portion of said at least two layers of said sealing element so as to close said passageway, thereby sealing the container; and
(f) removing said closure head from the container.
2. The method of claim 1 , wherein said deployment of said closure head brings said closure head into direct contact with the container.
3. The method of claim 1 , wherein said bonding together said least a portion of said at least two layers of said sealing element includes bringing a bonding head into contact with a top layer of said sealing element so as to close said passageway.
