Filter tip and filter stick pre-filled with large-particle materials

Abstract

The invention provides a filter tip pre-filled with large-particle materials. The filter tip is composed of a filter element, the large-particle materials, forming paper or groove-shaped cellulose paper. The forming paper wraps the filter element, and the large-particle materials are pre-buried in the filter element. The particle diameter of the large-particle materials ranges from 1.0 to 4.0 mm, and the distance between the buried position and the sucking end of the filter tip is greater than 6.0 mm. A flavour ingredient is contained in the large-particle material, or an absorbent material ingredient is contained in the large-particle materials. A layer of surface film may be arranged on the outer surface of the large-particle materials, and the surface film is broken due to the temperature of smoke in the case that the filter tip is sucked, so that a flavour is easy to emit, or an adsorption effect is easy to act. A filter stick pre-filled with large-particle materials can be formed in the case that a plurality of filter tips pre-filled with large-particle materials are integrally connected. The filter tip provided by the invention can add the flavour of a cigarette, or improve the adsorption capacity for smoke. The internal large-particle materials cannot be sucked in a mouth by mistake, and moreover, the flavour and the adsorption capacity of the large-particle materials are greatly preserved during production and storage, and can exert the corresponding effects during sucking.

Description

technical field [0001] The invention relates to a filter tip or a filter stick of a cigarette, in particular to a filter tip or a filter stick pre-prepared with fragrance or adsorption function particles. Background technique [0002] The filter (or filter rod) of a cigarette is constructed from a filter element and a forming paper (or forming paper). The filter element of the commonly used filter tip (or filter rod) is completely made of acetate fiber or polypropylene fiber, and its filtering effect on smoke is completely realized by acetate fiber or polypropylene fiber, which has poor filtering effect and no fragrance enhancement , personalized display and other special functions. [0003] In the patent specification with the application patent number 201020509008.8, a "cigarette filter with activated carbon particles" is introduced. ; Activated carbon is sprayed in the filter rod near the end of the cigarette. When the smoke passes through the filter rod, it is first a...
