Aerosol Can Disposal Device
The safe disposal of aerosol cans requires that the containers be
depressurized to permit the removal and treatment of content. This is
accomplished using a device which works in the following manner.
In use, an aerosol can 1 (Fig. 1) which is to be disposed of is placed on an
adjustable holder 2. The holder is adjustable by means of a removable pin 3
which is placed into the appropriate hole 4 which meets the desired height
requirements for the can.
The device's head assembly 5 is actuated downward on a Z axis by the
action of a lever 6 which makes contact with a top plate 7. This causes springs 8
to be placed under compression and head assembly 5 is lowered such that an
opening 9 in head assembly 5 moves over the top of can 1, thus securing the
can. A seal between the top of can 1 and the opening 9 is provided by a Teflon
gasket 10 on the beveled surface of the opening.
As lever 6 continues downward, a second set of springs 11 (Fig. 2) is
similarly placed under compression, and cylindrically shaped protusion 12 on
head assembly 5, which houses punches 13, fits into a mating counterbore 14 of
base 15 to prevent the uncontrolled venting of material from the aerosol can 1.
As the device continues downward, three hollow punches 13 are used to pierce
the can 1.
A second seal 16, a rubber gasket, makes contact with the bottom of the
counterbore 14 (Fig. 2) to prevent the uncontrolled venting of can contents. The
punches 13 are tapered to m...
