The device includes a cylindrical casing to hold a heat sealer, a battery power supply and a vacuum pump. The vacuum pump includes a piston reciprocated by a transmission rod and a flywheel through a motor to draw off air from a thermoplastic bag for making it into a vacuum status. The heat sealer includes a head having a sealing tip extended out of the cylindrical casing and electrically connected to the battery power supply to produce heat for sealing thermoplastic bags.

Abstract: A garment hanger comprises a hook member coupled with a garment supporting frame by a pivot joint. The hook member can be rotated within a fixed degree of angle relative to the garment supporting frame so that the garment hanger can be conveniently hung on a clothes-line for holding a garment to keep it in shape. Several garment hangers can be connected in series by a hook joint, for holding several garments, to reduce space occupation.
