Abstract
A vacuum sealer includes: a housing comprising a vacuum chamber therein; a vacuum pump in fluid communication with the vacuum chamber; a sealing mechanism adjacent a periphery of the vacuum chamber; a valve positioned and configured to releasably seal the vacuum chamber, the valve movable between a first position, in which the valve forms a seal with the sealing chamber, and a second position, in which the valve does not form a seal with the sealing chamber; and a controller operatively connected with the vacuum pump, the sealing mechanism, and the valve. The controller is configured to move the valve from the first position to the second position during sealing.
