Design rectangular bin outline with total 30 L inner volume to occupy minimal floor area and raise space utilization rate inside compact kitchen layouts. Paste anti slip rubber pads on bin bottom corners to increase ground friction force and stop pets or accidental bumps from tipping the whole bin over. Build outer frame from rust proof stainless steel to blend harmoniously with various kitchen decoration styles and wipe surface stains conveniently for lasting sleek look. Integrate damping slow close mechanism on lid parts to eliminate closing noise, and lift lids manually to ninety degrees angle to fix open state for continuous waste throwing. Add external pull handles on inner barrel sides to take out containers for dumping waste, and punch dedicated holes to fix trash bags and avoid liner shifting during usage.
