Abstract
A tip for being attached to a wrapper containing a smokable substance. The tip includes a tube having a generally cylindrical shape, having two ends each forming an opening at opposite ends of said tube. The openings are fluidly connected to each other by a chamber between the two ends, the chamber and said two ends being axially aligned. A first one of the two ends has a t-shaped opening and a second one of the two ends has a circular opening. The second end has an outside diameter less than an outside diameter of the first end. A method for making the tip is also described.

A tip for being attached to a wrapper containing a smokable substance, said tip comprising a tube having a generally cylindrical shape, having two ends each forming an opening at opposite ends of said tube, said openings fluidly connected to each other by a chamber disposed between the two ends, the chamber and said two ends being axially aligned, wherein a first one of said two ends has a t-shaped opening (105) and a second one of said two ends has a circular opening (109), said second end having an outside diameter less than an outside diameter of said first end, wherein said first end has a thickness which is greater than a thickness of a wall of said tube and said t-shaped opening extends from a surface of said first end through said thickness of said first end.
A tip manufactured according to a method of manufacturing a tip for use with smokable substances, the method comprising:
- continuously rotating a tube having a first end along its longitudinal axis in one direction;
- applying heat in a horizontal and vertical direction to said first end of the rotating tube;
- squeezing said heated first end with rollers and inserting a rotating plug, said rotating plug having a taper from a first end of said plug to a second end of said plug with a t-shape in cross-section, into said first heated end of said tube wherein said tube and said plug rotate in a same direction and a same speed, wherein said first heated end has a thickness which is greater than a thickness of a wall of said tube;
- removing said rollers and t-shaped plug and creating a scratch on said tube a distance from said heated end corresponding to a length of a manufactured tip using a scoring wheel applied to said tube at said distance, wherein after removing said t-shaped plug from said heated first end, said heated first end has a t-shaped opening which extends from a surface of said heated first end to an interior portion of said heated first end;
- applying second heat to said tube at said created scratch;
- clamping said end with a rotating chuck and spraying a mist of water at said scratch to create a thermal shock to said tube at said scratch to separate said tube into two pieces separated at said distance forming a first piece having a first end and a second end, said first piece corresponding to said manufactured tip and a second piece corresponding to a remaining length of said tube;
- applying third heat to a section of said first piece between said second end of said first piece extending a distance less than one half of said length;
- and
- squeezing said heated section with tapered rollers to taper a diameter of said first piece along said heated section wherein a diameter at said second end of said first piece is less than a diameter of said first piece extending from said second end of said first piece.
