  • Patent number: 8342185
    Abstract: The present document describes a twin-chamber humidifying tube that permits an even spread of moisture on each side of a cigar for up to six months without drying out thanks to the twin chamber system in the tube. The present invention also allows the recovery of dried cigars. Apart from the humidifying role, the invention provides an advertising opportunity since cigars stored in it can be viewed from the outside.

  • Patent number: 8327856
    Abstract: An environmentally degradable cigarette filter includes a filter element of a bloomed cellulose acetate tow and a plug wrap surrounding said filter element. A weak organic acid and a pH adjusted inorganic ester salt are encapsulated in a matrix material which is in contact with the tow. The pH adjusted inorganic ester salt has a pH less than or equal to 8. When the cigarette filter is discarded into the environment, water liberates the weak acid and the ester salt from the matrix material. The weak acid hydrolyzes the ester liberating a strong acid. The strong acid catalyzes the degradation of the cellulose acetate tow. (The weak acid also hydrolyzes the cellulose acetate tow, but after the strong acid is generated, the strong acid becomes the dominant acid catalyst for the cellulose acetate tow degradation.

  • Patent number: 8307833
    Abstract: An ashtray assembly for temporarily storing and containing rubbish, such as the ash and butts of cigarettes and cigars. In one aspect, the ashtray assembly can include a base assembly and an insert assembly. The base assembly can comprise a flexible body. The flexible body can include a storage container adapted to receive the rubbish. The flexible body can be made of a flexible material, such as a silicon-containing polymer, such that the flexible body can be manufactured by a molding process. Because the flexible body can be a silicon-container polymer, it may discolor when a lit end of a cigarette makes contact with the base assembly. The insert assembly can comprise an extinguishing member adapted to extinguish cigarettes, cigars, or both. The extinguishing member is preferably made of a generally non-marking and rigid material. The insert assembly can provide structural integrity and can be removably secured within the base assembly.
