Retractable Dustbin / Dustbin

Retractable Dustbin

In our daily life,we use dustbins ordinarily.However,we sometimes meet
some trouble,such as :1.the trash bag is not fit for dustbin(the cover of
dustbins are too small or too big for trash bag).2.We produce many kinds
of garbage everyday but not properly separate them but fix them together
.We cut an “U-SHAPE”gap in the dustbin,then wecan use two trash bag to
separate garbage and when the trash bag is two small ,the “U-SHAPE”gap
and its easy deformation material ensures enough room for us to squeeze it
into a smaller one .
