Description

Rollable end sealing block, sealing method thereof and heating cigarette comprising rollable end sealing block

Technical Field

The invention belongs to the technical field of heating cigarettes, and particularly relates to a reelable end sealing block, a sealing method thereof and a heating cigarette comprising the reelable end sealing block.

Background

With the improvement of living standard, people pay more attention to health problems of themselves, and in recent years, attention to smoking health problems is high. In order to meet the changing consumption demands, various heating nonflammable cigarettes for replacing the traditional cigarettes are developed in various enterprises at home and abroad.

The heating non-burning cigarette is the section of making a cigarette smoke of heating cigarette, and its receptivity that produces the taste of flue gas is better, and the heating non-burning cigarette of current commercialization mainly includes section of making a cigarette, cavity supporting section, cooling section and filter tip section, and the form of tobacco has in the section of making a cigarette: reconstituted tobacco sheets, cut tobacco, granular tobacco materials, blocky tobacco materials and the like which are filled orderly or unordered. When the tobacco in the smoke generating section is heated, the flavor and fragrance loaded on the tobacco and the smoke generating agent are evaporated to generate smoke.

The prior art generally fills the tobacco particles in the tobacco rod or cartridge with segments of the smoke particles, for example, the distal lip end of the segment of smoke particles is sealed with a sealing film/sleeve and the other end is sealed with a perforated closure, which can cause problems:

1. in order to facilitate filling of tobacco particles, the particulate cigarette directly uses an empty tube as the outermost reel. The sealing film/sealing sleeve is fixed at the end of the hollow pipe of the cigarette by means of adhesive or extrusion. The side end of the sealing film/the side end of the sealing sleeve are exposed outside, when the exposed part of the cigarette is easily rubbed with the outside to be stressed in the transportation or filling process of the cigarette, the sealing film/the sealing sleeve is easily separated from the empty tube when the side end of the sealing film/the sealing sleeve is stressed.
