Abstract

The utility model provides a dislocation slot filter rod relates to cigarette technical field, including circular shape filter core (1) and parcel cellulose paper (2) outside, be provided with a plurality of sections slot segments (3) on cellulose paper (2), slot (4) of every section slot segment (3) all encircle filter core (1) and arrange and along axial parallel arrangement, wherein slot (4) of some slot segments (3) are divided into a plurality of groups, be equipped with blank section (5) interval between every group slot (4), slot (4) of at least one section slot segment (3) adjacent rather than are also divided into a plurality of groups equally, and every group slot (4) all correspond with a blank section (5) position of adjacent slot segment (3), form the slot segment group of staggered arrangement. Have the advantage that the outward appearance is novel, the degree of distinguishing is high, the filter effect is good, make behind the filter tip ditch groove section and blank section interval can see through the outer packaging layer and show, can improve the product degree of distinguishing.

Description

Staggered groove filter rod

Technical Field

The utility model relates to the technical field of cigarette, concretely relates to staggered arrangement's slot filter rod.

Background

The traditional grooved filter stick is made by processing cellulose diacetate tow, special cellulose paper and filter stick wrapping paper as main raw materials, and the grooves are arranged on the cellulose paper between the tow and the wrapping paper. The effect of slot is the region that forms a section low pressure drop, makes the flue gas pass outer shaping paper when passing through from the low pressure drop district easily, produces high-efficient filter effect. However, the longitudinal groove structure enables the smoke of the cigarette to only travel along a single direction, so that the impact force of the smoke is too large, and the filtering effect of the special cellulose paper cannot be fully exerted.

Disclosure of Invention

The utility model discloses the technical problem that will solve is: aiming at the problems, the groove filter stick arranged in a staggered mode is provided.

The technical solution of the utility model is that: a staggered groove filter stick comprises a circular filter element and cellulose paper wrapped outside the filter element, wherein a plurality of groove sections are arranged on the cellulose paper, grooves of each groove section are arranged around the filter element and are arranged in parallel along the axial direction, grooves of some groove sections are divided into a plurality of groups, blank section intervals are arranged among the grooves of each group, the grooves of at least one adjacent groove section are also divided into a plurality of groups, each group of grooves corresponds to a blank section of an adjacent groove section in position to form a staggered groove section group, and after the grooves are cut into filter stick sections, each filter stick section at least comprises a group of staggered groove sections formed by two groove sections containing blank sections.

The technical effects of the utility model are that: have the advantage that the outward appearance is novel, the degree of discerning is high, the filter effect is good, make behind the filter tip ditch groove section can see through the outer packaging layer with blank section interval and show, can improve the product degree of discerning. When the smoke passes through the staggered grooves, the smoke flow direction can also be staggered, the flow path and the flow time of the cigarette smoke in the filter tip are increased, harmful impurities such as tar and nicotine in the smoke are reduced under the same groove length, and the smoke is more relaxed. Is suitable for all thick cigarette filter sticks, medium cigarette filter sticks, thin cigarette filter sticks and the like.

Detailed Description

As shown in fig. 1 and 2, a staggered grooved filter stick comprises a circular filter element 1 and a cellulose paper 2 wrapped outside the filter element 1, and is characterized in that a plurality of groove sections 3 are arranged on the cellulose paper 2, grooves 4 of each groove section 3 are arranged around the filter element 1 and are arranged in parallel along the axial direction, grooves 4 of some groove sections 3 are divided into a plurality of groups, blank sections 5 are arranged between every two groove sections 4, the grooves 4 of at least one adjacent groove section 3 are also divided into a plurality of groups, each group of grooves 4 corresponds to the blank sections 5 of the adjacent groove section 3, staggered groove section groups are formed, and after the grooves are cut into filter stick sections, each filter stick section at least comprises a staggered groove section group formed by two groove sections 3 containing blank sections 5.

The number of the blank sections 5 of one section of the groove section 3 is 1 to 3.

After being cut into the filter rod segments, each filter rod segment comprises three groove segments 3, wherein one groove segment 3 is formed by arranging grooves 4 without blank segments 5, and the other two groove segments are formed by arranging the groove segments 3 with the blank segments 5 in a staggered mode.

The thickness of the cellulose paper 2 is 160 to 220 μm.

2 or 4 filter rod segments can be obtained after each filter rod is cut.

The cut filter stick sections can be compounded with other functional filter stick sections to form filter sticks with more functions. Blank segment intervals can be arranged between the groove segments to adjust the resistance absorption value.
