Abstract: An apparatus is disclosed. The apparatus has a body member including a beverage-container-receiving cavity, an aperture disposed on the body member, and a movable member disposed on the body member, the movable member having a beverage-container-puncturing portion. The beverage-container-puncturing portion is selectively movable into the beverage-container-receiving cavity via the aperture.

Abstract: A paint can channel perforating apparatus includes a perforating member, a stiffening brace and a plurality of perforating bits. The perforating bits are arranged normal to the plane defined by the perforating member. A protective housing may be adapted to enclose the perforating member and the rim of a paint can. The protective housing includes at least one cross member arranged parallel to the stiffening brace and a plurality of guides sized to accept and direct the stiffening brace linearly. A shaft may be fixedly attached to the stiffening brace and slideable relative to an orifice defined within one of at least one of the cross members. Further a spring may be positioned around the shaft and between a handle and the cross member to return the perforating bits to a rest position after the channel has been pierced by the perforating bits.

Abstract: The invention features implementation of a flat triangular blade which has wo cutting edges and a sharp point. The blade is caused to move pointwise across a cylindrical can's diameter, with the plane of the blade perpendicular to the can's axis, so that the point pierces the can, the two cutting edges slice through the can in both directions around the can's circumference, and the point again, diametrically oppositely, pierces the can. The inventive removal of the residual contents and propellants from a spent aerosol can is optimally effective, because the invention divides the can into two separate parts, concomitantly subdividing the can's internal components.

Abstract: A can opener has an elongated rectangular base plate on which a can support box is centrally mounted. Four right angle corner rails extend upwardly from corners of the support box. The rails are connected by side support braces which form a square around midpoints of the corner rails. A top guide plate is secured to upper ends of the corner rails. A pair of slide bearings in the top guide plate mount a pair of slide rods. A transversely extending cross bar is secured to upper ends of the slide rods. The cross bar has a handle grip at each end. A blade mounting plate is secured to the lower ends of the slide rods. Four triangular tempered steel blades are secured to the side edges of the blade mounting plate. The blades extend perpendicularly downwardly from the blade mounting plate. L-shaped side support rods extend from opposite sides of the base plate to the side support braces. A pair of coiled springs extend between the transverse cross bar and the side support rods.
