A self-extinguishing safe cigarette

Background technique

The utility model relates to a cigarette with self-extinguishing function.

technical field

Smoking may also cause fires. In many cases, careless smokers, such as falling asleep while smoking, drop their cigarettes on flammable items such as clothes, furniture or paper; or throw cigarette butts around irresponsibly, Fire caused by negligence.

According to the American Burn Association and the U.S. federal government, in the United States, fires caused by smoking kill about 900 people and injure 2,500 people each year, causing economic losses of up to 400 million U.S. dollars. The Canadian federal government plans to force cigarette manufacturers to produce cigarettes that are less likely to cause fires. The country's health department has routinely proposed changes to relevant management regulations, aiming to change the way cigarettes are burned and reduce the number of deaths caused by fires. In December 2002, the country issued a consultation paper listing new fire protection requirements and new standards. The new regulations can force tobacco companies to produce products that prevent careless smokers from inadvertently causing fire hazards. Cigarettes designed in accordance with the new regulations can burn at a relatively low temperature, and can also self-extinguish within a few minutes without continuous puffing.

Philip Morris is urging the U.S. government to ask Congress to implement a national standard for tobacco companies to produce cigarettes that automatically extinguish quickly when smokers are not smoking. The purpose is to reduce the number of smoking-related fires in the United States each year. The number of hundreds of deaths. A key reason Philip Morris supports the federal request has to do with a New York state law. Namely New York State Law 2000 Chapter 284 (New York State 2000 Chapter 284). The law was revised to establish cigarette fire safety standards and limit fire risks. It became law on August 16, 2000 with the approval of the Governor, and came into effect after January 1, 2003. The transition period is 180 days.

Its main contents include:

1. Cigarettes sold in this state:

(1) After being lit, the cigarette will automatically extinguish after a period of non-puffing; or (2) The cigarette will not ignite office items, furniture, linens, or interior items.

2. The safety cigarettes shall comply with:

(1) Does not increase the hygienic standards for consumers' health; (2) The safety cigarettes should meet the food hygiene management standards.

Beginning in July 2003, only self-extinguishing cigarettes may be sold in New York State, the law said.

The United States has been brewing for decades to formulate corresponding regulations, and New York has become the first state to require the use of fire-safe cigarettes.

Massachusetts, Minnesota, New Jersey and Rhode Island are all considering similar measures, according to the National Conference of Federal Legislators.

If these states approve the law, it will be a nightmare for cigarette production and sales, said Mark Berlinder, deputy general counsel of Philip Morris Management. New Zealand is also considering similar regulations.

There are not many patents on safe cigarettes that are automatically extinguished without smoking for a period of time after being ignited in China, but there are some deficiencies in all of them.

Publication No. CN2520682Y (safety cigarette), application number 93241773.6 (safety cigarette case), 92202727.7 (fireproof safety cigarette case), 95214416.6 (flame-stop safety cigarette) etc. relate to a set of cigarettes that can move toward the other end with a flame-retardant Material sleeves. Obviously, the cigarette case is an additional tool for smoking, which is inconvenient to use and cannot completely eliminate the flameout problem of the cigarette butt.

Publication No. CN1376828A (fireproof and dustproof cigarette paper) involves weaving glass fibers into a mesh (shape), and bonding ultra-thin cigarette paper with ordinary adhesive on the inner surface, which has the functions of isolation and fire prevention, self-extinguishing, and overall treatment of soot. Function. However, this method has complex manufacturing process and high cost, and is not suitable for large-scale industrial production, and its application value is extremely low.

Utility model content

The purpose of this utility model is to provide a self-extinguishing safety cigarette that can be automatically extinguished within a few minutes under the premise of discontinuous smoking.

The purpose of this utility model is achieved in the following manner:

The utility model comprises a filter tip and a shredded tobacco part, and one or more flame-retardant annular bands coated with a flame-retardant coating are printed on the cigarette paper coated outside the shredded tobacco.

According to the fire-proof self-extinguishing cigarette according to claim 1, the width of the flame-retardant ring is 3mm-5mm.

The flame retardant coating can be coated on the front or back of the cigarette paper, and coating on the back of the cigarette paper, that is, the side contacting the shredded tobacco, will have a better flame retardant effect and will not affect the appearance of the cigarette.

By having the utility model structural feature in the cigarette finished product as the test sample, the cigarette finished product that the ordinary paper coil is connected is the control sample, carry out automatic flame-out comparison test:

Light several test sample and control sample cigarettes respectively, gently clamp the end of the filter tip of the cigarette, place the filter tip downwards upright, or place it horizontally, and let it ignite until it extinguishes itself.

The test shows that: when the test sample of cigarettes wound by flame-retardant coil paper reaches the flame-retardant band, the cigarettes will automatically extinguish; while the cigarettes of the control sample coiled by ordinary coil paper will continue to burn. Burn until close to the filter tip, and some will burn off part of the filter tow before extinguishing.

The utility model has the advantages of simple structure, easy further processing, and is more suitable for the actual situation of cigarette production.
