| Abstract: |
The weighted garbage can with legs has a receptacle with a rounded weighted base such that the empty garbage can will tend to remain upright and will upright itself if tipped. The weighted garbage can with legs also has retractable legs that function in conjunction with a spring suspended inner platform to retract when the garbage can is empty and extend as the receptacle is filled. The legs extend as the receptacle is filled to stabilize the can as the self-uprighting tendency is overcome when the filled receptacle becomes top-heavy.
