Description

Cigarette with hygienic protection structure and manufacturing method thereof

The present invention relates to a cigarette wrapped with a protective cover in a filter portion of a cigarette, and a method of making the same. Background technique

As shown in Fig. 1 and Fig. 2, at present, the manufacturing process of the filter cigarette is roughly as follows: 1 roll the cigarette main body, prepare the filter rod and the tipping paper; 2 use the crimping device to connect the cigarette main body and the filter rod by the tipping paper. Together, make finished cigarettes; 3 use packaging equipment to package finished cigarettes into boxed cigarettes.

It is well known that when people smoke cigarettes, they usually take the cigarettes from the filter box and take them out of the cigarette case. Then they can take it or pass it on to others. Because people often carry many germs on their hands, they are in the process of taking cigarettes. These germs easily adhere to the filter of cigarettes and cause various diseases through the inhalation of people into the body. In addition, it is not difficult to see from the above process that after the finished cigarettes are made, they are packaged into boxed cigarettes. In the process, there is also the possibility of being contaminated; therefore, the existing structural form of the filter cigarette has certain health and safety risks. To this end, on May 30, 2001, the China Consumers Association issued the sixth consumer warning in the same year: Smoking is an important way to get sick from the mouth.

A variety of solutions have been proposed for the health and safety of cigarette filters. There are three typical types:

1. Start with the cigarette pack of the cigarette, by changing the structure of the cigarette box, such as: side open box, open box at two ends, open box at the side corner, open box at the bottom, drawer type cigarette case, push-pull cigarette case, pop-up cigarette case Etc., in order to change the traditional way of smoking, change the original hand-held filter to a cigarette in the middle or bottom of the hand-held cigarette, so as to avoid contamination of the cigarette filter as much as possible. The technical solution described in Chinese Patent ZL011 31 3951. 1 is representative of such a method.

For the current soft pack and hard pack cigarettes, although the above method has a certain effect, it does not completely prevent the cigarette filter from being contaminated. Because when people pick up the cigarette case, it is still possible to bring the germ into the box. Even if the hand touches the middle of the cigarette, the hand must be in contact with other cigarettes in the cigarette case, such as bacteria on the hand. Other cigarettes in the box must be contaminated Dyeing. In addition, the cigarette case is placed in the pocket, and the gap in the cigarette case may also become a passage for the bacteria to enter. In addition, the cigarette making process is complicated and consumes a lot of materials (if too much paper, pad spring, belt line, etc.), the production cost is high, and the form is single, which is also disadvantageous for its promotion and application.

2. Start with the handling of the cigarette into the mouth, by placing a protective sheath outside the cigarette filter to avoid contamination. Specifically, there are only two ways of adding a protective cover to the cigarette filter and a protective cover for the entire cigarette. Chinese Patent No. 94206093. 8 describes the application form in which only a protective cover is applied to the filter.

Although such methods can prevent cigarettes from being contaminated before smoking, there are still defects such as repeated packaging, complicated manufacturing processes, and large consumption of packaging materials.

3. Starting from antibacterial and bactericidal aspects, the sunscreen is opened on the cigarette case, the ultraviolet ray is used for sterilization, and the tipping paper with antibacterial and bactericidal function is used to inhibit the growth of bacteria. Such a method is described in Chinese Patent Application No. 02146697.

This kind of method belongs to passive anti-pollution. It does not contain pollution from the source. The chemical composition of the antibacterial and sterilized tipping paper itself will cause certain harm to the human body. Summary of the invention
