In the recent years there have been some attempts at bins that specifically addresses the usage of plastic bags. The ‘Urbano’ is another similar attempt – with the design thoughtfully being doubled up as a plastic-bag storage:
Another twist to make this design even more compelling: extra bags can be stored under the one in use, pushed down by the handles and tucked beneath them. Replacing the bags, then, is even easier than in a traditionally designed trash can – you just pull up the new bag after your remove the old one and hook its handles around the catches provided.
My little question is just – when the bin has some rubbish in it (but not full enough to throw it away yet), you can’t really store it (it’s too much of a mess to lift the rubbish-bag up, tuck the bag in, and put the rubbish bag in again). But overall, neat design!
