ABSTRACT:
Disclosed herein is a vacuum sealer, which exhausts air from a thermal adhesive vacuum bag containing products and then heats and seals the open end of the vacuum bag. The vacuum sealer includes a lower body. An upper body is pivotably mounted to the lower body in such a way as to engage with the lower body. A heater is installed in either or both the lower body or/and the upper body, and heats and seals a vacuum bag. A vacuum space creating member is installed in either or both the lower body or/and the upper body, and isolates an end of the vacuum bag which is evacuated from an exterior, thus creating a vacuum space. A vacuum pump is coupled via a tube to an exhaust hole communicating with the vacuum space created by the vacuum space creating member.
