We see these rubbish bins everywhere. They have been designed to outwit the roaming population of bears who manage to open pretty much every kind of bin ever used. This new bin requires you to slip your hand into the slot on the top and trigger a small latch to open it. So far the bears haven't figured out how to open them. Their paws are probably too big anyway. They could, of course, train their kids how to do it. Their little paws may just get in the slot.
