Technical Examples
  1. A vacuum sealing apparatus has an inlet portion and an intermediate portion. The inlet portion is adapted to couple to, or insert into, a container to be vacuum sealed. The intermediate portion connects to a vacuum source, such as an in-house vacuum system. When the vacuum source is active, air is drawn in through the inlet portion. The vacuum sealing apparatus may also have a contamination filter disposed therein that substantially impedes contaminants from entering the vacuum source. In another configuration, the vacuum sealing apparatus is self-contained and includes a dedicated vacuum source.
