Filter Cigarette Holder

Abstract

This invention relates to a filtering device for use with cigarettes and other smoking products. Embodiments of the invention include a cigarette holder equipped with pressure filtering. Embodiments may be smaller than about 20 mm, include a separate semi-closed collection chamber to prevent “backwash” of tar which would otherwise occur due to the filter's small size, require less material than current cigarette filters, enable more effective filtration, increase filter capacity for holding tar, and provide additional benefits resulting from the greater likelihood of use by smokers. Another embodiment would include the replacement of the plastic casing with paper, creating a filter made mostly of naturally biodegradable material.

Description

[0001]This application claims priority benefit of: U.S. Provisional Patent Application Ser. No. 62 / 337,483, filed May 17, 2016.FIELD OF THE INVENTION AND DESCRIPTION OF THE PRIOR ART[0002]In conventional cigarette filtration technology, pressure filter cigarette holders used both in the United States and abroad consist of a filter about 25 mm in length, which includes a transparent cigarette holder with a mouthpiece. Current, known pressure cigarette filters are longer than at least about 25 mm, or 2.5 cm.[0003]The function of pressure-based filtered cigarette holders is to reduce the damage of cigarettes by means of capturing the tar contained in the cigarette smoke along with reducing the nicotine and carcinogenic compounds that cigarettes deliver.SUMMARY[0004]Embodiments of the invention include a cigarette pressure filter device 20 mm or smaller designed for removing and retaining 66% to 90% or more of tar or nicotine in a cigarette, which filter is held in place by the cigarett...

AI Technical Summary

Benefits of technology

The invention is a new cigarette filter that has improved filtration efficiency and durability. It can filter more cigarettes and has a longer lifespan compared to existing filters. The filter requires less plastic and reduces waste. Additionally, it prevents tar from flowing back towards the user and can be used with multi-bore cigarette holders. Overall, the invention provides a more effective and durable filtering solution for smoking.

Problems solved by technology

Given the much smaller inner area and volume, chamber and overall size of embodiments of this innovative filter, should the design aspects not fall within the parameters required, the filter will either not filter sufficiently or it will be unable to retain accumulated tar resulting in a sudden massive release, also called “backwash”.

Other failures caused by designs outside the parameters include overly restricting air flow, resulting in a difficult “draw” and making an otherwise functioning filter very difficult or impossible to for a smoker to use.

Also, changes to the affixation spike and sleeve can result in the filter constantly falling off the cigarette.

A reduction of the length of the collection chamber below the design length may result in a reduction of filtration below acceptable parameters and or in “backwash” situation.

Plastic cigarette holders are known to have harmful effects on the environment.
