Zusammenfassung: | The present invention discloses a method and apparatus for closing a resealable vacuum bag while the vacuum bag is still inside the vacuum chamber of a heat-sealing vacuum packing machine. The resealable bag may be automatically closed, at least temporally, by either (1) the compressive forces that vacuum packing machines exert against the sides of vacuum bags, or (2) an autonomous, vacuum-activated device that closes the open section of the vacuum bag's sealing strip. Finally, the cost of the resealable vacuum bag may be minimized by eliminating the air valve that is imbedded in the sides of conventional resealable vacuum bags, but which is superfluous for the present invention. |
