Patent number: 11058147Abstract: A freezable smoking pipe with integrated reflective particles for producing a cool, dry smoke that flows to the mouth, and providing an ornamental smoking experience. The pipe comprises a bowl and a mouthpiece that are in communication through a shaft. The shaft is defined by a transparent and continuous shaft outer wall and shaft inner wall that form a channel. The bowl is defined by a transparent and continuous bowl outer wall and bowl inner wall. A cooling composition consisting of isopropyl, water, and reflective particles is sealed between the walls. The cooling composition can be frozen to cool the smoke that flows through the channel of the shaft. The duration of cooling is at least partially dependent on the space between the inner and outer walls, and the concentration of isopropyl. The reflective particles are visible through the walls and reflect light to create an ornamental smoking experience.Type: GrantFiled: June 21, 2017Date of Patent: July 13, 2021Inventor: Christopher L.

Patent number: 6006757Abstract: A cigarette holder completely encloses the lit end of a cigarette providing purification for both sidestream smoke and mainstream smoke. It has two concentric tubes with the lit cigarette placed in the inner tube and purifying agent placed in the volume between the inner tube and the outer tube. A chimney effect is produced wherein air flows through an air port past the lit cigarette to keep it burning. The sidestream smoke passes through the purifying agent and is discharged into the environment. The filter tip of the lit cigarette extends through a mouthpiece and the smoker exhales smoke through openings in the same mouthpiece. The mainstream smoke passes through the same purifying agent, in a direction opposite to the flow of the sidestream smoke, and is then discharged into the environment.Type: GrantFiled: May 14, 1998Date of Patent: December 28, 1999Inventor: Edward Lichtenberg

Patent number: 5529078Abstract: A smoker's box for reducing pollution caused by smoking a cigarette. A housing has a first and second portion, the first portion defining a cavity, and the second portion defining a fan chamber. A venting channel allows gases to pass between the first and second housing portions. A lighter is provided to light a cigarette within the cavity. A mouthpiece and a cigarette sleeve for holding a cigarette define an inhalation channel open to the surrounding atmosphere. A replaceable cartridge includes a burn chamber in which the cigarette burns, a smoke treatment chamber adjacent to the burn chamber, a particulate filter between the burn chamber and the smoke treatment chamber, and smoke treatment means within the smoke treatment chamber for absorbing exhaled smoke passing within the smoke treatment chamber to produce a decontaminated gaseous mixture.Type: GrantFiled: May 9, 1994Date of Patent: June 25, 1996Assignee: Truce, Inc.Inventors: Miles R. Rehder, Richard D. Iwanski, Judson R. Meyers, Steven M. Patten
