Abstract:
A hole-forming device comprising:a support plate fittable to a bottom of a can;said support plate having a cut-out opening formed therein;a hole-forming body formed within said cut-out opening of said support plate;deformable means for permitting raising of said hole-forming body from an orientation co-planar with the surface of said support plate to a roughly perpendicular orientation;said deformable means including at least first and second twistable connecting pieces connecting said hole-forming body and said support plate; anda hole-formation support slidably supporting said hole-forming body in a raised state at a position separated from the surface of said support plate; andwhen said hole-forming body is in a raised state, a lower side of said hole-forming body projects beyond a surface of said support plate, whereby a lower part of said hole-forming body is available to receive a force effective to urge said hole-forming body upward into piercing contact with a bottom of said can.
