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.

Claims22

Dependent claims

In combination, a puncturing device and a metal can, the metal can comprising:

a cylindrical sidewall having a first diameter disposed around a central axis;
and
a bottom portion comprising:
a circular concave dome-shaped central portion extending radially outwardly from the central axis and terminating in an annular base portion spaced axially apart from the sidewall and having a second diameter disposed around the central axis and less than the first diameter;
and
an annular inclined connecting wall portion extending between the circular central portion and the sidewall,
the metal can having a height,
the puncturing device comprising:
a frame comprising one or more vertical walls extending vertically above a supporting surface, perpendicular to the supporting surface, to a height at least equal to the height of the metal can, an upper portion of one or more of the vertical walls providing an arm support;
and
an arm rotatably attached to the arm support, the arm comprising first and second puncturing elements extending downward when the arm is in a puncturing position in which the arm extends laterally, parallel to the supporting surface,
wherein the puncturing elements are spaced apart from each other, and are positioned and configured so that the metal can is positionable upside-down on the supporting surface with the sidewall extending vertically above the supporting surface and the annular base portion above the sidewall, so that when the arm is rotated from a position above the metal can to the puncturing position, the first puncturing element punctures the connecting wall portion of the metal can and the second puncturing element punctures the concave dome-shaped central portion of the metal can.

and
an annular inclined connecting wall portion extending outward from the annular base portion to the sidewall,
the puncturing device comprising an arm rotatably attached to a vertical support, the arm comprising first and second puncturing elements that extend downward when the arm is in a puncturing position in which the arm extends laterally from the vertical support,
wherein the puncturing elements are spaced apart from each other and positioned so that the metal can is positionable upside-down on a supporting surface with the sidewall extending vertically above the supporting surface and the annular base portion above the sidewall, so that when the arm is rotated from a position above the metal can to the puncturing position, the first puncturing element punctures the connecting wall portion of the metal can and the second puncturing element punctures the concave dome-shaped central portion of the metal can.
