Safety disposal can for inflammable materials

Claim 2

A safety disposal can comprising a container formed of a plastics material and having a completely and continuously closed and unbroken inner surface on the walls thereof and with said inner surface being free of all attachments thereto, said inner surface terminating at a neck-like opening forming a communicating passageway through a wall of said container to receive waste material placed in said container and for emptying said container after it is filled with waste material, the outside surface of said wall of said container being formed with a thickened fin resting on a raised platform, said fin projecting outwardly away from said outside surface of said raised platform container to give added strength to the container in a plane substantially perpendicular to the surface of said container, and said platform giving added strength to the surface of said container wall in a plane normal to said fin, said fin and said platform abutting and supporting said necklike opening. attachment means fitting against said fin and said platform for securing a separate structure to the outside surface of said container, and means for attaching said attachment means to said fin without breaking through said inner surface of the container.

Claim 3

The safety disposal can of claim 1 wherein said thickened fin and raised platform are formed along a parting line produced by the multiple part mold used in forming the container.

Claim 4

The safety disposal can of claim 1 wherein said separate structure is a handle mounted in vertical alignment with the center of gravity of said container, a spring biased cap for normally closing said opening, and means responsive to movement of said handle for selectively controlling the opening and closing of said cap.

Claim 5

The can of claim 1 and a metal fire arrester means suspended and locked inside said passageway.

Claim 6

The can of claim 1 wherein said neck-like opening comprises an internal annular capture member formed therein, and a cup-like fire arrester means suspended and locked inside said opening, said cup having a perforated bottom.

Claim 7

The can of claim 1 wherein the bottom of said can has three integral dependent feet molded therein, wHerein one of said feet is approximately twice as long as each of the other two feet.

Claim 8

The can of claim 6 wherein said long foot is positioned under said opening.

Claim 9

A safety disposal can comprising a container formed of a plastics material and having a completely and continuously unbroken inner surface on the walls thereof free of all attachments thereto, said inner surface terminating at an opening forming a communicating passageway through a wall of said container to receive waste material placed in said container and for emptying said container after it is filled with waste material, the outside surface of said wall of said container being formed with a thickened fin thereon projecting outwardly from the wall, attachment means fitted against said fin for securing a separate structure to the outside of said container, means for attaching said attachment means to said fin without breaking through said inner surface of the container, said separate structure comprising a handle mounted in vertical alignment with the center of gravity of said container, a hinged spring bias cap for normally closing said opening, means responsive to the movement of said handle for selectively controlling the opening and closing of said cap, said means for attaching said attachment means to said fin comprising an elongated bracket with an L-shaped cross-section attached to each side of said fin by means of metal fasteners passing through the brackets and the fin, said bracket supporting, at least, said handle, and selectively controllable linkage means for engaging said handle for opening said container when said handle is moved to a predetermined position.

Claim 10

A safety disposal can comprising a container formed of a plastics material and having a completely and continuously unbroken inner surface on the walls thereof free of all attachments thereto, said inner surface terminating at an opening forming a communicating passageway through a wall of said container to receive waste material placed in said container and for emptying said container after it is filled with waste material, the outside surface of said wall of said container being formed with a thickened fin thereon projecting outwardly from the wall, attachment means fitted against said fin for securing a separate structure to the outside of said container, means for attaching said attachment means to said fin without breaking through said inner surface of the container, said separate structure comprising a handle mounted in vertical alignment with the center of gravity of said container, a hinged spring bias cap for normally closing said opening, means responsive to the movement of said handle for selectively controlling the opening and closing of said cap, said means for attaching said attachment means to said fin comprising an elongated bracket with an L-shaped cross-section attached to each side of said fin by means of metal fasteners passing through the brackets and the fin, said bracket supporting, at least, said handle, and selectively controllable linkage means for engaging said handle for opening said container when said handle is moved to a predetermined position.

Claim 11

The safety disposal can of claim 8 wherein said controllable linkage comprises an elongated means which may be selectively attached between said cap and said handle whereby movement of said handle opens said cap when said linkage is connected.

Claim 12

The safety disposal can of claim 9 and another of said controllable linkage is an elongated means selectively connected between said fin and said handle, to hold said handle and said cap, when said cap is in an open position.

Claim 13

The safety disposal can of claim 10 wherein each of said elongated means comprises a hook and said handle has a pin for capturing said hook.

Claim 14

The safety can of claim 11 wherein at least some of the metal parts attached to said fin are plastic coated.
