Double-layer visual cavity blasting bead filter stick

Abstract

The invention discloses a double-layer visual cavity blasting bead filter stick, and relates to a filter stick for manufacturing a cigarette filter tip. A functional filter stick section comprises a functional filter stick section a (2) and a functional filter stick section b (3); an empty space for containing a blasting bead (1) is reserved between the blasting bead and a base; a layer of inner transparent forming paper (4) wraps the peripheries of the functional filter stick section a (2), the functional filter stick section b (3) and the blasting bead (1); the positions, corresponding to the functional filter stick section a (2) and the functional filter stick section b (3), outside the inner transparent forming paper (4) are each wrapped with a cellulose diacetate tow layer (5), and the two cellulose diacetate tow layers (5) and the space between the two cellulose diacetate tow layers (5) are wrapped with outer transparent forming paper (6). The double-layer visual cavity blastingbead filter stick is more novel in appearance, brings strong impact to human vision, better improves smoke circulation and suction feeling, and is superior to a ternary visual cavity blasting bead filter stick in the aspects of tar reduction and harm reduction.

Description

technical field [0001] The present invention relates to filter rods for use in the manufacture of cigarette filters. Background technique [0002] The existing ternary visible cavity pop-bead filter rods for manufacturing cigarette filters have thick, thin, medium and medium-fine specifications. This kind of ternary visible cavity blasting bead filter rod is relatively novel in appearance, but its form is relatively simple, and there is only one direction of smoke flow, the feeling of suction will be poor, and its performance in reducing coke and harm is not obvious enough. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a double-layer visible cavity blasting bead filter rod with better suction feeling and more obvious defocus and damage reduction performance. [0004] The technical solution of the present invention is: a double-layer visible cavity pop-up bead filter rod, including a functional filter stick sec...
