ANIMAL TRAP
The mouse's own weight tilts the tube and seals it inside.
A hollow airtight tube pivots on a base, with a disposable bag rubber-banded to one end and a magnetically latched door at the other. The mouse enters the open end and moves toward bait in the bag; once its weight passes the pivot point, the tube tilts to the catch position. The tilting cams the door shut, where a permanent magnet and a rubber sheet hold it hermetically sealed. The mouse asphyxiates inside the bag, which is then pulled off the tube and discarded without being touched.
“Preferably the bags are of an opaque color so that the rodent inside cannot be seen. This makes the disposal problem more palatable especially to housewives.”— William A. Lindelow, from the specification
And the world did not beat a path to his door.
