Filter tip and filter stick pre-buried with solid capsules

Abstract

The invention provides a filter tip and a filter stick pre-buried with solid capsules. The filter tip comprises forming paper, a filter element and the solid capsules, wherein the forming paper wraps the periphery of the filter element, and the solid capsules are pre-buried in the filter element. The solid capsule is composed of a large hemispherical shell, a solid medical material and a small hemispherical shell; and the solid capsule presents a sphere shape, an ellipsoid shape or a medical capsule shape. The solid medical material has the ingredients of a natural flavour, an artificial flavour or Chinese herbal medicines or an absorbent material. When the filter tip is kneaded by fingers of a human body, the large hemispherical shell and the small hemispherical shell are deformed, and an obvious gap is generated therebetween, and the smell of the solid medical material can be emitted, or an adsorption effect is generated simultaneously. A filter stick pre-buried with solid capsules is formed in the case that a plurality of filter tips are integrally connected. According to the invention, the solid medical material is slowly released and slowly sucked, thus meeting requirements on the production and the storage life of the filter tip; and the solid medical material is good for exerting effects by the kneading during sucking. According to the filter tip and the filter stick pre-buried with solid capsules provided by the invention, the flavour of a cigarette can be added, the adsorption capacity of the filter tip is improved, and the harm on human health is reduced.

Description

technical field [0001] The invention relates to a filter tip or a filter stick of a cigarette, in particular to a filter tip and a filter stick pre-embedded with a solid capsule capable of flavor and adsorption. Background technique [0002] The filter tip (or filter rod) of an existing cigarette is constructed of a filter element and a forming paper (or forming paper). The structure and shape of the filter tip are single, and it is not good enough in terms of flavor enhancement, flavor preservation and enhanced adsorption. [0003] The utility model with the patent No. 201020664191.9 filed by the applicant discloses a "capsule-containing rayon filter", which is composed of rayon filter core, capsule and forming paper. Forming paper is wrapped on the periphery of the man-made fiber filter core, and the man-made fiber filter core contains capsules, and the capsules contain solutions of natural flavors, artificial flavors or Chinese herbal medicines. The liquid capsule in th...
