Method and apparatus for eliminating oxygen in the filling of a flexible bag with a beverage utilizing sources of inert gas, vacuum, and beverage. A filling head regulates the injection of inert gas and applies a vacuum to the flexible bag the bag spout. The bag spout is separately rinsed of oxygen prior to recapping the same on the flexible bag.

Systems, methods, and apparatuses for treating and sealing perishable products in bulk bins and large bulk open top packaging are included. A modified atmosphere of industrial gas (i.e., nitrogen) and product specific treatments are injected within the contents of the liner bag or bin enclosure at the conclusion of the cooling cycle, in conjunction with or just after as the liner bag or open top bin enclosure is sealed. The methods and apparatuses provide alternative processes that can be applied manually or automated to seal of the bin liner bag or bin enclosure and then independently or in conjunction with cooling provide for the controlled and contained injection of modified atmosphere industrial gas treatments (i.e., nitrogen), sanitizer, and/or other functional substances to protect, preserve, or enhance the quality of the perishable product.

The present invention relates to an auto injector (1) comprising a prefilled liquid medicament container, a hollow auto injector body (2) housing the medicament container. The auto injector body (2) has an elongated part, a first end side (21) and a second end side (22) and at least one through hole (3) arranged between the end sides (21, 22). The through holes (3) allow for flow of gas through the auto injector body (2) when the auto injector body (2) houses the medicament container. The invention further relates to a method comprising inserting the auto injector (1) into the package via an opening in a non-inert environment, and, in a non-inert environment and under atmospheric pressure: replacing the air in the package with inert atmosphere by one or several cycles of removing air and inserting inert gas through the opening, wherein the air and inert gas in part flows through the at least one through hole (3) of the auto injector (1). The method further comprises sealing the opening under vacuum.

A method of preserving an oxygen sensitive item is disclosed. The method involves injecting at least 0.15 gram of an inert gas into a container comprising the oxygen sensitive item and oxygen, without raising a pressure within the container above 10 psig, to form a barrier layer of the inert gas between the oxygen sensitive item and the oxygen in the container without displacing all of the oxygen from the container.
