Vacuum sealer

Abstract

A vacuum sealer of the present invention includes a main body and a hood hinged to the main body. A heater is installed on the main body, and engages with a pressing member provided on the hood to heat and seal an open end of a bag. A vacuum pump is provided in the main body to be coupled to a suction nozzle communicating with the open end of the bag. Further, a straight line-shaped sealing member is provided as a predetermined position on the main body and another sealing member is provided as a position corresponding to the straight line-shaped sealing member.
