Moisture-preserving method for cigarettes

Abstract

The invention discloses a moisture-preserving method for cigarettes. After a smoker firstly opens a cigarette case to get out a cigarette, a sealed moisture-preserving body made of a moisture-preserving material is opened and arranged at the space of the taken-out cigarette inside the cigarette case, so that the moisture-preserving body can create a small environment which is suitable for preserving the moisture of the cigarettes inside the cigarette case to prevent excessive interference of the surrounding big environment to the moisture of the cigarettes. The moisture-preserving body is an integral body which is similar to the cigarette in shape, or comprises a plurality of sections; when the moisture-preserving body is adopted integrally, the outer part of the integral body is sealed by a plastic thin film; when the moisture-preserving body comprises a plurality of sections, the outer part is sealed in a segmented manner; the moisture-preserving body is opened in a segmented manner during usage to adjust the exposed area of the moisture-preserving material for controlling a moisture absorption rate or a moisture desorption rate of the moisture-preserving material, so that the moisture of the cigarette is not insufficient or excessive, thereby preserving appropriate moisture of the cigarette during smoking, and preserving the taste of the cigarette to be not worsened due to moisture change.

Description

technical field [0001] The invention relates to a method for keeping cigarettes with suitable moisture, and is especially suitable for keeping moisture in cigarettes sold in cigarette packs. Background technique [0002] At present, the moisture in shredded tobacco has a great influence on the taste of cigarettes when smoking. Too dry or wet will make the taste drastically worse. It is usually used to increase the airtightness of the box and stick packaging to keep the moisture in the cigarette, but when the consumer buys and opens the package to smoke, the sealing function of the cigarette is destroyed, and the cigarette gradually absorbs or loses moisture, reaching the temperature and humidity of the surrounding environment. Balanced and consistent moisture. In the dry season or region, the moisture in the cigarette is lost, and in the wet season or region, the cigarette absorbs moisture and the moisture increases, making the cigarette too dry or humid. At present, there...
