Abstract:
A device for puncturing a metal can having a cylindrical sidewall and a bottom portion with an annular concave central portion terminating in an annular base portion. The base has an annular inclined connecting wall portion extending outward from the annular base portion to the sidewall. The device includes a frame with vertical walls extending above a supporting surface to a height at least equal to the height of the metal can, and an arm rotatably attached to the walls. The arm has two or more puncturing elements extending downward when the arm is in a puncturing position in which the arm extends laterally. The puncturing elements are configured so the can is positionable upside-down on a supporting surface so that when the arm is rotated into the puncturing position, the first puncturing element punctures the connecting wall and the second puncturing element punctures the concave central portion.

Claim (Index 11):
A method of puncturing a metal can having a cylindrical sidewall having a first diameter disposed around a central axis, and a bottom portion having a concave central portion extending radially outwardly from the central axis and terminating in an annular base portion having a second diameter disposed around a central axis and less than the first diameter, and a connecting wall portion connecting the annular base portion to the sidewall, the method comprising the steps of:\n providing first and second puncturing elements, the first puncturing element configured to puncture the metal can to produce a hole having a diameter of between 3 mm and 8 mm, the second puncturing element configured to puncture the metal can to produce a hole having a diameter of between 1 mm and 5 mm; puncturing the connecting wall portion of the bottom portion with the first puncturing element to produce a first hole having a diameter of between 3 mm and 8 mm; and puncturing the concave central portion of the bottom portion with the second puncturing element to produce a second hole having a diameter of between 1 mm and 5 mm.
