ABSTRACT:
A vacuum sealer includes a base member formed with a hollow platform having a first sealing ring secured on the platform and a support. A drawing hole is defined in the top of the platform within the first sealing ring. A heating plate is laterally secured on a front edge of the platform. A pumping device is mounted on the support for drawing out the air in a plastic bag that is purposed to be sealed. A transparent presser has a rear side pivotally mounted on the platform and selectively pressed on the top of the platform. A second sealing ring is secured on a bottom of the presser and fully airtightly abuts the first sealing ring when the presser is pressed on the platform.
